+# 架构完善计划
+
+> PLC 型号：**西门子 S7-200 Smart**，通信协议：**HslCommunication S7Net**
+>
+> 恢复的 4 组代码均有明确设计意图，但实现不完整。本计划按优先级排列，逐步将它们从"占位代码"推进到"生产可用"。
+
+---
+
+## 阶段零：项目档案接线（扬杰二厂急需，快速补全）
+
+**目标**：将 `ProjectProfile` 中已定义但未接线的模型字段接入到服务层/ViewModel/UI。
+
+**现状**：
+- `ProjectProfile` 定义了 8 个子配置（Pump/Tank/Gauge/Sensor/DI/DO/AlarmThresholds/ViewTemplate）
+- 核心路径（泵/水箱/仪表/传感器）已完整可用
+- 但 DI/DO/报警阈值/泵扩展地址/ViewTemplate 只有模型，下游没有接线
+
+**步骤**：
+
+| # | 任务 | 涉及文件 | 说明 |
+|---|------|----------|------|
+| 0.1 | 通用 DI 接入 | `PlcDataModel.cs` + `PlcPollingService.cs` + `ProjectViewModel.cs` + `ProjectView.axaml` | PlcPolling 读取 DigitalInputs → ViewModel 显示变频器故障 |
+| 0.2 | 通用 DO 接入 | `ProjectViewModel.cs` + `ProjectView.axaml` | 日流量复位/复位按钮点动写入 |
+| 0.3 | 泵扩展地址接入 | `PumpItemViewModel.cs` + `PlcPollingService.cs` + `ProjectView.axaml` | 中控/屏控状态读取、日台时清零、手自动状态 |
+| 0.4 | 报警阈值接入 | `ProjectViewModel.cs` | AlarmThresholds → AlarmService 超限报警 |
+| 0.5 | ViewTemplate 接入 | `MainViewModel.cs` | 根据 Profile.ViewTemplate 选择布局 |
+
+**完成标准**：
+- [ ] 扬杰二厂 JSON 中配置的所有地址均可读取/写入
+- [ ] 变频器故障等 DI 信号在 UI 上可见
+- [ ] 日流量复位、日台时清零等 DO 操作可执行
+- [ ] 压力/液位超限自动触发报警
+
+---
+
+## 阶段一：DI 渐进式迁移（基础，其他阶段的前置条件）
+
+**目标**：让 Service 可测试、可替换，为后续阶段打好基础。
+
+**现状**：
+- 接口已定义（IPlcService / IAlarmService / IConfigService / IDatabaseService / IAuthService）
+- ServiceLocator 已实现，但零调用方
+- 所有 Service 是 static class，不实现接口
+
+**步骤**：
+
+| # | 任务 | 涉及文件 | 说明 |
+|---|------|----------|------|
+| 1.1 | 选择 1 个低风险 Service 试点 | `ConfigService` | 它无状态、无并发，最适合试点 |
+| 1.2 | ConfigService 从 static 改为实例类 | `ConfigService.cs` | 实现 `IConfigService`，保留 `Instance` 静态属性做兼容 |
+| 1.3 | ServiceLocator 注册 ConfigService | `ServiceCollectionExtensions.cs` | `services.AddSingleton<IConfigService>(ConfigService.Instance)` |
+| 1.4 | 逐批替换调用方 | 所有 ViewModel/Service | `ConfigService.GetConfig()` → `ServiceLocator.GetService<IConfigService>().GetConfig()` |
+| 1.5 | 重复 1.2~1.4 覆盖其他 Service | 按依赖顺序：IConfigService → IDatabaseService → IAuthService → IPlcService → IAlarmService | 每完成一个 Service 跑一次全量测试 |
+| 1.6 | （可选）引入构造函数注入 | `App.axaml.cs` | `services.BuildServiceProvider()` + ViewModel 通过构造函数接收依赖 |
+
+**完成标准**：
+- [ ] 所有 Service 实现对应接口
+- [ ] ServiceLocator 有实际调用方（至少 ConfigService 全量替换完成）
+- [ ] 现有功能不受影响
+
+---
+
+## 阶段二：DeviceStateMachine 完善（设备状态管理）
+
+**目标**：让泵/风机的状态转换有规则、可审计。
+
+**现状**：
+- `DeviceStateMachine` 类已定义状态（Stopped/Running/Fault/Maintenance）和转换
+- `DeviceStateMachineManager` 已实现，硬编码"5 泵 + 2 风机"
+- 使用 Stateless 库，但**没有与 PlcPollingService/AlarmService 联动**
+- 方法体只记日志
+
+**步骤**：
+
+| # | 任务 | 涉及文件 | 说明 |
+|---|------|----------|------|
+| 2.1 | 从 ProjectProfile 读设备列表 | `DeviceStateMachine.cs` | `InitializeDefaultDevices()` 改为从 `ProjectService.CurrentProfile` 读设备，不再硬编码 |
+| 2.2 | 接入 PLC 数据驱动状态转换 | `DeviceStateMachine.cs` | 订阅 `PlcPollingService.DataUpdated` 事件，根据 `PumpRunning`/`PumpFault` 信号触发状态转换 |
+| 2.3 | 添加状态变更事件 | `DeviceStateMachine.cs` | `event Action<DeviceStateChange> StateChanged`，供 UI/通知消费 |
+| 2.4 | 接入 AlarmService | `AlarmService.cs` | 设备进入 Fault 状态时自动触发报警；报警恢复时自动转 Maintenance |
+| 2.5 | ViewAViewModel 消费状态机 | `ViewAViewModel.cs` | 替换手写的 `UpdateDeviceStatuses`，改读 DeviceStateMachine 的状态 |
+| 2.6 | 状态变更持久化 | `DeviceStateMachine.cs` | 写入 `equipment_statuses` 表，支持历史查询 |
+
+**完成标准**：
+- [ ] 泵/风机状态由状态机管理，不再用散落的 bool 字段
+- [ ] 状态转换合法（Fault 不能直接 → Running）
+- [ ] 状态变更事件可供 UI 和通知消费
+- [ ] 设备数量从项目配置读取
+
+---
+
+## 阶段三：WorkflowService 完善（工艺流程编排）
+
+**目标**：让污水处理的多步骤流程可控、可配置。
+
+**现状**：
+- `WorkflowService` 是简化版工作流引擎（Elsa 失败后的降级方案）
+- 只有 `RegisterSampleWorkflows()` 里的日志占位
+- 没有与任何业务服务联动
+
+**步骤**：
+
+| # | 任务 | 涉及文件 | 说明 |
+|---|------|----------|------|
+| 3.1 | 定义工作流模型 | `Models/WorkflowDefinition.cs` | `WorkflowDefinition`（步骤列表）、`WorkflowStep`（条件 + 动作 + 下一步） |
+| 3.2 | 从 JSON 配置加载工作流 | `WorkflowService.cs` | `Workflows` 配置节 → `WorkflowDefinition` 列表 |
+| 3.3 | 实现工作流执行引擎 | `WorkflowService.cs` | `ExecuteAsync(workflowId)`：按步骤执行，支持条件分支、等待、超时 |
+| 3.4 | 实现内置动作 | `WorkflowService.cs` | 预置动作：`StartPump`/`StopPump`/`CheckLevel`/`SendNotification` 等 |
+| 3.5 | 与 DeviceStateMachine 联动 | `WorkflowService.cs` | 工作流步骤可以查询/等待设备状态 |
+| 3.6 | UI 展示工作流状态 | `ViewFViewModel.cs` | 显示当前运行的工作流、步骤进度、历史执行记录 |
+
+**完成标准**：
+- [ ] 可通过 JSON 配置定义工作流
+- [ ] 工作流能驱动实际控制（启停泵、阀门切换）
+- [ ] 工作流执行有审计日志
+
+---
+
+## 阶段四：PlcDrivers 接入（多品牌 PLC 支持）
+
+**目标**：让项目支持西门子以外的 PLC 品牌。
+
+**现状**：
+- 7 个驱动文件已恢复（Siemens/AllenBradley/Mitsubishi/Omron/ModbusTcp）
+- `PlcDriverFactory` 完整，但 `PlcService` 直接硬编码 `SiemensS7Net`
+- `PlcConfig` 地址格式是西门子专用的（VD100, Q0.0）
+
+**步骤**：
+
+| # | 任务 | 涉及文件 | 说明 |
+|---|------|----------|------|
+| 4.1 | PlcConfig 添加协议选择 | `PlcConfig.cs` + `yzwater-config.json` | 新增 `PlcProtocol` 配置项，默认 `SiemensS7` |
+| 4.2 | PlcService 使用 PlcDriverFactory | `PlcService.cs` | `ConnectAsync()` 中根据协议创建对应驱动，替换硬编码的 `SiemensS7Net` |
+| 4.3 | 统一地址格式 | `PlcConfig.cs` + 各驱动 | 定义通用地址模型，各驱动负责转换为品牌专用地址 |
+| 4.4 | UI 协议选择 | `ViewBView.axaml` + `ViewBViewModel.cs` | 参数设置页添加 PLC 品牌/协议下拉框 |
+| 4.5 | 集成测试 | `tests/` | 至少对 ModbusTcp 做一次真实连接测试 |
+
+**完成标准**：
+- [ ] `yzwater-config.json` 可配置 PLC 协议
+- [ ] 至少 2 种协议可正常读写（Siemens + 另一品牌）
+- [ ] UI 可切换协议
+
+---
+
+## 依赖关系
+
+```
+阶段零（项目档案接线）← 扬杰二厂急需，最先做
+    ↓
+阶段一（DI 迁移）← 基础，建议最先做（可与阶段零并行）
+    ↓
+阶段二（状态机）← 需要 DI 让状态机可注入
+    ↓
+阶段三（工作流）← 依赖状态机的设备状态查询
+阶段四（多品牌 PLC）← 独立，可随时启动（当前项目用 S7-200 Smart + Hsl S7 协议）
+```
+
+## 时间估算
+
+| 阶段 | 预估工作量 | 优先级 |
+|------|-----------|--------|
+| 阶段零：项目档案接线 | 1~2 天 | ⭐⭐⭐ 最高（扬杰二厂急需） |
+| 阶段一：DI 迁移 | 2~3 天 | ⭐⭐⭐ 最高（基础） |
+| 阶段二：状态机 | 3~4 天 | ⭐⭐⭐ 高（工业控制核心） |
+| 阶段三：工作流 | 4~5 天 | ⭐⭐ 中（自动化增值） |
+| 阶段四：多品牌 PLC | 2~3 天 | ⭐ 按需（有新项目时） |

+# AutoFMA 借鉴实施计划
+
+## 项目背景
+
+基于对 AutoFMA（自动光学量测机上位机）项目的分析，提取可借鉴的架构设计和实现模式，应用到 YZWater3（污水处理厂监控系统）中，提升系统的健壮性、可维护性和性能。
+
+## 借鉴点清单
+
+| 序号 | 功能 | 来源 | 优先级 | 状态 |
+|:---:|:---|:---|:---:|:---:|
+| 1 | 数据库在线备份增强 | DatabaseBackupService | P0 | ✅ |
+| 2 | 数据保留清理服务 | DataRetentionService | P0 | ✅ |
+| 3 | 配置服务热加载 | ConfigService | P1 | ✅ |
+| 4 | 审计日志 Channel 异步写入 | AuditService | P1 | ✅ |
+| 5 | 日志缓冲服务 | LogBufferService | P2 | ✅ |
+| 6 | 表驱动状态机 | SessionStateMachine | P1 | ⏭️ 跳过（Stateless 已覆盖） |
+| 7 | 连接状态集中管理 | ConnectionStatusService | P2 | ✅ |
+| 8 | 用户锁定持久化 | UserService | P3 | ✅ |
+| 9 | 报警历史 Channel 写入 | AlarmMonitorService | P3 | ✅ |
+| 10 | 在线升级委托注入 | UpdateService | P3 | ✅ |
+
+## 第二批实施说明
+
+### 6. 表驱动状态机 — 跳过
+YZWater3 已使用 Stateless 库实现 `DeviceStateMachine`（`Configure().Permit()` 即转移表）。
+AutoFMA 的 `SessionStateMachine` 是为"扫码→驱动→测量→MES"多阶段会话定制，YZWater3 无对应业务流程，不重复引入。
+
+### 7. 连接状态集中管理
+- `PlcService`/`HubServer`/`HubClient` 添加状态变更事件
+- 新增 `ConnectionStatusService` 单例：订阅各服务事件，统一存储，提供显示文本 + 状态变更通知
+
+### 8. 用户锁定持久化
+- `User` 模型新增 `FailedLoginAttempts`/`LockoutUntil` 字段
+- `AuthService` 锁定逻辑从内存字典改为数据库持久化（重启不丢失）
+
+### 9. 报警历史 Channel 写入
+- `AlarmService` 两处直接 `Insertable` 改为 `Channel<AlarmRecord>` 后台串行写入
+- 退出时 flush（复用 AuditService 模式）
+
+### 10. 在线升级委托注入
+- 新增 `UpdateService`（Core 层）：版本管理 + `SetTriggerAction` 委托注入
+- UI 层实际更新逻辑后续接入（Avalonia 无 AutoUpdater.NET 官方支持，先搭架子）
+
+---

+---
+
+## P1 - 架构升级
+
+### 3. 配置服务热加载
+
+**当前实现**: `ConfigService.cs` - 手动加载/保存
+
+**借鉴来源**: `AutoFMA.Core/Services/ConfigService.cs`

+- ✅ `ConfigChanged` 事件通知
+- ✅ 权限校验（Engineer 以上才可修改）
+
+**实施文件**:
+- `src/YZWater.Core/Services/ConfigService.cs` - 增强现有实现
+
+---
+
+### 4. 审计日志 Channel 异步写入

+
+---
+
+## P2 - 性能优化
+
+### 5. 日志缓冲服务

+
+---
+
+## 配置项扩展
+
+在 `SystemConfig` 中新增以下配置：
+
+```csharp
+// 数据保留配置
+public DataRetentionConfig DataRetention { get; set; } = new();
+
+public class DataRetentionConfig
+{
+    /// <summary>报警记录保留天数（默认 90 天）</summary>
+    public int AlarmRecordRetentionDays { get; set; } = 90;
+
+    /// <summary>流量记录保留天数（默认 360 天）</summary>
+    public int FlowRecordRetentionDays { get; set; } = 360;
+
+    /// <summary>模拟量记录保留天数（默认 360 天）</summary>
+    public int AnalogRecordRetentionDays { get; set; } = 360;
+
+    /// <summary>审计日志保留天数（默认 365 天）</summary>
+    public int AuditLogRetentionDays { get; set; } = 365;
+}
+
+// 备份配置
+public BackupConfig Backup { get; set; } = new();
+
+public class BackupConfig
+{
+    /// <summary>是否启用定时备份</summary>
+    public bool EnableScheduledBackup { get; set; } = true;
+
+    /// <summary>定时备份间隔（小时，默认 24 小时）</summary>
+    public int BackupIntervalHours { get; set; } = 24;
+
+    /// <summary>保留备份数量（默认 7 个）</summary>
+    public int KeepBackupCount { get; set; } = 7;
+}
+```
+
+---
+

+}
+```
+
+**切换项目**：
+- 方法一：修改 `yzwater-config.json` 中的 `ActiveProject`，重启程序
+- 方法二：运行时在「参数设置」页选择项目，点击保存（热切换）
+
+### 西门子 S7-200 Smart 连接指南
+
+1. **硬件连接**：PLC 以太网口 → 交换机 → 上位机
+2. **PLC 配置**：使用 STEP 7-Micro/WIN SMART 设置 IP 地址（如 192.168.1.100）
+3. **程序配置**：
+   ```json
+   {
+     "PlcIp": "192.168.1.100",
+     "PlcPort": 102,
+     "PlcProtocol": "SiemensS7"
+   }
+   ```
+4. **测试连接**：在参数设置页点击「测试连接」
+5. **地址格式**：
+   - `VD100` - 变量存储区双字（4字节浮点数）
+   - `M1.0` - 标志位
+   - `Q0.1` - 输出位
+   - `I0.1` - 输入位
+
+---
+
+## TLS 配置
+
+### 服务端（HubServer）
+
+1. 准备 PFX 证书文件（如 `server.pfx`）
+
+2. 在 Windows 绑定证书：
+```powershell
+# 导入证书
+Import-PfxCertificate -FilePath server.pfx -CertStoreLocation Cert:\LocalMachine\My
+
+# 获取证书指纹
+$thumbprint = (Get-PfxCertificate server.pfx).Thumbprint
+
+# 绑定到端口
+netsh http add sslcert ipport=0.0.0.0:8765 certhash=$thumbprint appid="{00000000-0000-0000-0000-000000000000}"
+```
+
+3. 修改配置文件：
+```json
+{
+  "HubPort": 8765,
+  "UseTls": true,
+  "CertificatePath": "C:\\YZWater\\server.pfx",
+  "CertificatePassword": "your_password"
+}
+```
+
+### 客户端（HubClient）
+
+修改配置文件：
+```json
+{
+  "HubServerUrl": "wss://server-ip:8765",
+  "IgnoreCertificateErrors": false
+}
+```
+
+> **注意**：自签名证书可设置 `IgnoreCertificateErrors: true`（仅测试环境）
+

+
+# 启动服务
+sudo systemctl start yzwater
+```
+
+### 性能优化
+
+#### SQLite 优化
+
+已在代码中自动启用：
+- WAL 模式（提升并发性能）
+- 64MB 缓存
+- 内存临时表
+
+#### 日志级别
+
+修改 `appsettings.json`：
+```json
+{
+  "Serilog": {
+    "MinimumLevel": {
+      "Default": "Information"
+    }
+  }
+}
+```
+
+### 常见问题
+
+#### 1. PLC 连接失败
+
+- 检查 PLC IP 和端口是否正确
+- 检查网络连通性：`ping <PLC_IP>`
+- 检查 PLC 是否支持 S7 协议
+- 查看日志：`Logs/log-*.txt`
+
+#### 2. WebSocket 连接断开
+
+- 检查服务端是否运行
+- 检查防火墙是否放行 8765 端口
+- 检查 Token 是否匹配
+- 客户端会自动重连（最大延迟 30 秒）
+
+#### 3. 数据库锁定
+
+SQLite 支持单写多读，高并发写入时可能锁表。解决方案：
+- 已启用 WAL 模式，支持并发读写
+- 减少写入频率（`DataLoggingService.FlowLogIntervalSeconds`）
+- 考虑迁移到 PostgreSQL（大规模部署）
+
+#### 4. 内存占用过高
+
+- 检查是否有内存泄漏（使用 `dotnet-trace`）
+- 调整数据保留天数：`DataRetentionDays`（默认 30 天）
+- 定期清理旧数据
+
+### 监控指标
+
+#### 应用指标
+
+- PLC 连接状态
+- WebSocket 客户端数
+- 活跃报警数
+- 数据库大小
+
+#### 系统指标
+
+- CPU 使用率

+# 依赖注入（DI）迁移指南
+
+## 概述
+
+YZWater3 已引入 `Microsoft.Extensions.DependencyInjection` 框架，采用**渐进式迁移**策略，从静态服务逐步过渡到依赖注入。
+
+## 当前状态
+
+### 已完成接口化
+
+- ✅ `INotificationService` - 通知服务（企业微信/钉钉/邮件）
+
+### 待迁移（保持静态访问）
+
+- `PlcService` - PLC 通信
+- `AlarmService` - 报警管理
+- `DatabaseService` - 数据库
+- `AuthService` - 认证授权
+- `ConfigService` - 配置管理
+- `HubServer` / `HubClient` - WebSocket 通信
+
+## 使用方式
+
+### 方式一：Service Locator（推荐过渡期使用）
+
+```csharp
+// 获取服务
+var notificationService = ServiceLocator.GetService<INotificationService>();
+
+// 发送通知
+await notificationService.SendAlarmNotificationAsync(alarm);
+```
+
+### 方式二：构造函数注入（最终目标）
+
+```csharp
+public class MyViewModel : ObservableObject
+{
+    private readonly INotificationService _notificationService;
+
+    public MyViewModel(INotificationService notificationService)
+    {
+        _notificationService = notificationService;
+    }
+
+    public async Task SomeMethod()
+    {
+        await _notificationService.SendAlarmNotificationAsync(alarm);
+    }
+}
+```
+
+### 方式三：静态访问（向后兼容）
+
+```csharp
+// 现有代码无需修改，继续使用静态类
+NotificationService.Instance.SendAlarmNotificationAsync(alarm);
+```
+
+## 迁移步骤
+
+### 第一步：配置 DI 容器
+
+在 `App.axaml.cs` 的 `OnStartup` 中：
+
+```csharp
+using Microsoft.Extensions.DependencyInjection;
+
+protected override void OnStartup(StartupEventArgs e)
+{
+    base.OnStartup(e);
+
+    // 配置 DI
+    var services = new ServiceCollection();
+    services.AddYZWaterCore();
+
+    var serviceProvider = services.BuildServiceProvider();
+    ServiceLocator.Configure(serviceProvider);
+
+    // 原有初始化代码...
+}
+```
+
+### 第二步：逐步迁移服务
+
+以 `PlcService` 为例：
+
+1. **创建实例类实现接口**
+
+```csharp
+// 新建 PlcServiceImpl.cs
+public class PlcServiceImpl : IPlcService
+{
+    // 实现接口方法...
+}
+```
+
+2. **静态类作为门面（保持兼容）**
+
+```csharp
+// PlcService.cs 保持静态类
+public static class PlcService
+{
+    private static IPlcService? _impl;
+
+    public static void Initialize(IPlcService impl)
+    {
+        _impl = impl;
+    }
+
+    public static bool IsConnected => _impl?.IsConnected ?? false;
+
+    public static Task<bool> ConnectAsync()
+        => _impl?.ConnectAsync() ?? Task.FromResult(false);
+
+    // 其他方法委托给 _impl...
+}
+```
+
+3. **在 DI 配置中注册**
+
+```csharp
+services.AddSingleton<IPlcService, PlcServiceImpl>();
+```
+
+4. **初始化静态门面**
+
+```csharp
+var plcService = serviceProvider.GetRequiredService<IPlcService>();
+PlcService.Initialize(plcService);
+```
+
+### 第三步：逐步替换调用方
+
+```csharp
+// 旧代码
+PlcService.ConnectAsync();
+
+// 新代码（ViewModel 中）
+public class MyViewModel
+{
+    private readonly IPlcService _plcService;
+
+    public MyViewModel(IPlcService plcService)
+    {
+        _plcService = plcService;
+    }
+
+    public async Task Connect()
+    {
+        await _plcService.ConnectAsync();
+    }
+}
+```
+
+## 接口定义
+
+### IPlcService
+
+```csharp
+public interface IPlcService
+{
+    bool IsConnected { get; }
+    Task<bool> ConnectAsync();
+    void Disconnect();
+    Task<byte[]?> ReadBytesAsync(string address, ushort length);
+    Task<float> ReadFloatAsync(string address);
+    Task<bool> ReadBoolAsync(string address);
+    Task<bool> WriteAsync(string address, byte[] value);
+    float ParseFloat(byte[] data, int offset);
+    bool ParseBit(byte[] data, int byteOffset, int bitIndex);
+}
+```
+
+### IAlarmService
+
+```csharp
+public interface IAlarmService
+{
+    bool HasActiveAlarm { get; }
+    int ActiveAlarmCount { get; }
+    void Start();
+    void Stop();
+    Task AcknowledgeAlarmAsync(int alarmId, string operatorName = "Operator");
+    Task AcknowledgeAllAsync(string operatorName = "Operator");
+    Task<List<AlarmRecord>> GetUnacknowledgedAlarmsAsync();
+    Task<List<AlarmRecord>> GetAlarmHistoryAsync(DateTime start, DateTime end);
+
+    event Action<AlarmRecord>? AlarmRaised;
+    event Action<AlarmRecord>? AlarmAcknowledged;
+    event Action? AlarmStateChanged;
+}
+```
+
+### INotificationService
+
+```csharp
+public interface INotificationService
+{
+    bool IsEnabled { get; set; }
+    void AddChannel(INotificationChannel channel);
+    void RemoveChannel(string channelName);
+    Task SendNotificationAsync(string key, string title, string message, NotificationLevel level);
+    Task SendAlarmNotificationAsync(AlarmRecord alarm);
+    Task SendEscalationNotificationAsync(AlarmRecord alarm);
+    Task SendPlcConnectionNotificationAsync(bool isConnected);
+}
+```
+
+## 测试示例
+
+使用 DI 后，可以方便地进行单元测试：
+
+```csharp
+[Fact]
+public async Task AlarmService_ShouldRaiseNotification_WhenAlarmTriggered()
+{
+    // Arrange
+    var mockNotification = new Mock<INotificationService>();
+    var alarmService = new AlarmService(mockNotification.Object);
+
+    // Act
+    alarmService.TriggerAlarm("Test", "Test alarm", 2);
+
+    // Assert
+    mockNotification.Verify(x => x.SendAlarmNotificationAsync(It.IsAny<AlarmRecord>()), Times.Once);
+}
+```
+
+## 迁移优先级
+
+1. **高优先级**（影响可测试性）
+   - `PlcService` - 核心业务逻辑
+   - `AlarmService` - 报警判断
+   - `AuthService` - 权限检查
+
+2. **中优先级**（影响模块化）
+   - `DatabaseService` - 数据访问
+   - `ConfigService` - 配置管理
+
+3. **低优先级**（相对独立）
+   - `HubServer` / `HubClient` - 通信层
+   - `AuditService` - 审计日志
+
+## 注意事项
+
+1. **向后兼容**：静态门面确保现有代码无需立即修改
+2. **渐进迁移**：可以逐个服务、逐个调用方迁移
+3. **测试覆盖**：迁移时补充单元测试
+4. **线程安全**：确保服务实例是线程安全的
+5. **生命周期**：注意服务的生命周期管理（单例/瞬态/作用域）

+
+## 启用通知服务
+
+在 `App.axaml.cs` 的 `StartServices()` 方法中添加：
+
+```csharp
+// 启用通知服务
+var notificationService = NotificationService.Instance;
+notificationService.IsEnabled = true;
+notificationService.ThrottleSeconds = 60;  // 同一报警至少间隔 60 秒
+
+// 添加企业微信通知
+var wechatWebhook = ConfigService.Instance.GetValue<string>("Notification:WeChatWorkWebhook");
+if (!string.IsNullOrEmpty(wechatWebhook))
+{
+    notificationService.AddChannel(new WeChatWorkNotification(wechatWebhook, new HttpClient()));
+    Log.Information("已启用企业微信告警通知");
+}
+
+// 添加钉钉通知
+var dingtalkWebhook = ConfigService.Instance.GetValue<string>("Notification:DingTalkWebhook");
+if (!string.IsNullOrEmpty(dingtalkWebhook))
+{
+    notificationService.AddChannel(new DingTalkNotification(dingtalkWebhook, new HttpClient()));
+    Log.Information("已启用钉钉告警通知");
+}
+
+// 添加邮件通知
+var emailConfig = ConfigService.Instance.GetSection("Notification:Email");
+if (emailConfig != null)
+{
+    var emailChannel = new EmailNotification(
+        emailConfig["SmtpServer"],
+        int.Parse(emailConfig["SmtpPort"] ?? "587"),
+        emailConfig["FromEmail"],
+        emailConfig["FromPassword"],
+        emailConfig["ToEmails"].Split(',')
+    );
+    notificationService.AddChannel(emailChannel);
+    Log.Information("已启用邮件告警通知");
+}
+```
+
+## 配置文件示例（yzwater-config.json）
+
+```json
+{
+  "Notification": {
+    "Enabled": true,
+    "ThrottleSeconds": 60,
+    "NotifyOnAlarm": true,
+    "NotifyOnEscalation": true,
+    "NotifyOnPlcDisconnect": true,
+    "WeChatWorkWebhook": "https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=YOUR_KEY",
+    "DingTalkWebhook": "https://oapi.dingtalk.com/robot/send?access_token=YOUR_TOKEN",
+    "Email": {
+      "SmtpServer": "smtp.example.com",
+      "SmtpPort": "587",
+      "FromEmail": "alarm@example.com",
+      "FromPassword": "your_password",
+      "ToEmails": "admin@example.com,operator@example.com"
+    }
+  }
+}
+```
+
+## 通知触发场景
+
+1. **新报警触发**：当液位、流量、设备故障等报警触发时
+2. **报警升级**：未确认报警超过 `EscalationMinutes`（默认 10 分钟）自动升级
+3. **PLC 连接断开**：PLC 通信中断，进入降级模式
+4. **PLC 连接恢复**：PLC 通信恢复正常
+
+## 通知限流
+
+- 同一报警在 `ThrottleSeconds`（默认 60 秒）内只发送一次
+- 防止报警风暴导致通知泛滥
+
+## 自定义通知渠道
+
+实现 `INotificationChannel` 接口：
+
+```csharp
+public class MyCustomNotification : INotificationChannel
+{
+    public string Name => "MyCustom";
+
+    public async Task SendAsync(string title, string message, NotificationLevel level)
+    {
+        // 实现你的通知逻辑
+        // 例如：SMS、Slack、Telegram 等
+    }

+# 多 PLC 协议支持
+
+## 概述
+
+YZWater3 基于 HslCommunication 库实现了多 PLC 协议支持，通过统一的 `IPlcDriver` 接口抽象，可以轻松切换不同品牌的 PLC。
+
+## 支持的协议
+
+| 协议 | 品牌 | 默认端口 | 说明 |
+|------|------|----------|------|
+| **Siemens S7** | 西门子 | 102 | S200/S200Smart/S300/S400/S1200/S1500 |
+| **Mitsubishi MC** | 三菱 | 6000 | Q 系列、iQ-R/iQ-F |
+| **Omron Fins** | 欧姆龙 | 9600 | CJ/CS/CP 系列 |
+| **Modbus TCP** | 通用 | 502 | 仪表、传感器、其他 PLC |
+| **Allen-Bradley** | AB | 44818 | ControlLogix/CompactLogix |
+
+## 使用方法
+
+### 方式一：通过工厂创建
+
+```csharp
+using YZWater.Core.Services.PlcDrivers;
+
+// 创建西门子 S7 驱动
+var driver = PlcDriverFactory.Create(
+    PlcProtocol.SiemensS7,
+    ipAddress: "192.168.1.100",
+    port: 102,
+    extraConfig: new Dictionary<string, object>
+    {
+        ["PlcSeries"] = "S200Smart"
+    }
+);
+
+// 连接
+var result = await driver.ConnectAsync();
+if (!result.IsSuccess)
+{
+    Console.WriteLine($"连接失败: {result.Message}");
+    return;
+}
+
+// 读取数据
+var floatResult = await driver.ReadFloatAsync("VD100");
+if (floatResult.IsSuccess)
+{
+    float value = floatResult.Content;
+    Console.WriteLine($"VD100 = {value}");
+}
+
+// 写入数据
+await driver.WriteFloatAsync("VD100", 123.45f);
+
+// 断开
+driver.Disconnect();
+driver.Dispose();
+```
+
+### 方式二：直接创建驱动
+
+```csharp
+// 西门子 S7
+var siemens = new SiemensS7Driver(SiemensPLCS.S1200);
+siemens.SetConnection("192.168.1.100", 102);
+
+// 三菱 MC
+var mitsubishi = new MitsubishiMcDriver();
+mitsubishi.SetConnection("192.168.1.101", 6000);
+
+// 欧姆龙 Fins
+var omron = new OmronFinsDriver();
+omron.SetConnection("192.168.1.102", 9600);
+omron.SetNodeNumbers(sa1: 0, da1: 0);  // 设置节点号
+
+// Modbus TCP
+var modbus = new ModbusTcpDriver();
+modbus.SetConnection("192.168.1.103", 502, station: 1);
+modbus.SetAddressStart(true);  // 地址从 0 开始
+
+// AB EtherNet/IP
+var ab = new AllenBradleyDriver();
+ab.SetConnection("192.168.1.104", 44818);
+```

+
+## 扩展新协议
+
+实现 `IPlcDriver` 接口：
+
+```csharp
+public class MyCustomDriver : IPlcDriver
+{
+    public string Name => "My Custom PLC";
+    public bool IsConnected { get; private set; }
+
+    public Task<OperateResult> ConnectAsync()
+    {
+        // 实现连接逻辑
+    }
+
+    public void Disconnect()
+    {
+        // 实现断开逻辑
+    }
+
+    public Task<OperateResult<byte[]>> ReadBytesAsync(string address, ushort length)
+    {
+        // 实现读取逻辑
+    }
+
+    // 实现其他接口方法...
+}
+```
+
+然后在 `PlcDriverFactory` 中添加：
+
+```csharp
+public static IPlcDriver Create(PlcProtocol protocol, ...)
+{
+    IPlcDriver driver = protocol switch
+    {
+        PlcProtocol.MyCustom => new MyCustomDriver(...),
+        // ...
+    };
+    return driver;
+}
+```
+
+## 注意事项
+
+1. **线程安全**：所有驱动实例都是线程安全的
+2. **连接管理**：使用完毕后必须调用 `Dispose()` 释放资源
+3. **错误处理**：检查 `OperateResult.IsSuccess` 判断操作是否成功
+4. **地址格式**：不同 PLC 的地址格式不同，请参考对应的文档
+5. **性能优化**：批量读取时使用 `ReadBytesAsync` 而非多次读取单个值
+
+## 性能对比
+
+| 协议 | 读取延迟 | 吞吐量 | 说明 |
+|------|----------|--------|------|
+| S7 | 10-50ms | 高 | 优化良好 |
+| MC | 10-50ms | 高 | 优化良好 |
+| Fins | 20-80ms | 中 | 相对较慢 |
+| Modbus | 50-200ms | 低 | 通用协议，开销大 |
+| AB | 20-100ms | 中 | 取决于标签复杂度 |
+
+## 故障排查
+
+### 连接失败
+
+1. 检查 IP 和端口是否正确
+2. 检查网络连通性：`ping <PLC_IP>`
+3. 检查 PLC 是否支持该协议
+4. 查看日志：`Logs/log-*.txt`
+
+### 读取失败
+
+1. 检查地址格式是否正确
+2. 检查地址是否超出 PLC 范围
+3. 检查数据类型是否匹配
+4. 查看 HslCommunication 的返回信息
+
+### 性能问题
+
+1. 使用批量读取而非单个读取
+2. 减少轮询频率
+3. 考虑使用 PLC 的主动推送（如 OPC UA）

+# PumpStation2D/3D 动态化实施计划
+
+## 目标
+
+将硬编码的 `PumpStation2DControl` 和 `PumpStation3DControl` 改造为数据驱动，能够根据 `ProjectProfile` 动态渲染任意数量/类型的设备。
+
+---
+
+## 现状分析
+
+### 当前架构（硬编码）
+
+```
+PumpStation2DControl
+├── Tank1LevelProperty ~ Tank4LevelProperty    ← 固定 4 个
+├── Pump1RunningProperty ~ Pump5RunningProperty ← 固定 5 个
+├── Fan1RunningProperty ~ Fan2RunningProperty   ← 固定 2 个
+└── Render(DrawingContext)
+    ├── DrawTank(index)     ← 位置硬编码
+    ├── DrawPump(index)     ← 位置硬编码
+    └── DrawFan(index)      ← 位置硬编码
+```
+
+**问题**：
+- 设备数量写死在控件属性里
+- 布局坐标硬编码（`x = 100 + index * 150`）
+- 无法适配不同泵站配置
+
+### 目标架构（数据驱动）
+
+```
+PumpStation2DControl
+├── Profile : ProjectProfile    ← 从项目档案读取设备列表
+├── LayoutEngine                ← 根据设备数量自动计算布局
+├── Renderers                   ← 复用现有 Renderer 绘制设备
+│   ├── TankRenderer
+│   ├── PumpRenderer
+│   ├── FanRenderer
+│   ├── ValveRenderer
+│   └── PipeRenderer
+└── Render(DrawingContext)
+    └── 遍历 Profile 设备，调用对应 Renderer
+```
+
+---
+
+## 实施步骤
+
+### 阶段一：数据模型扩展（1 天）
+
+#### 1.1 定义动态属性
+
+在 `PumpStation2DControl` 中用 `IList` 替代固定属性：
+
+```csharp
+// 移除硬编码属性
+// public double Tank1Level { get; set; }  ← 删除
+
+// 新增动态属性
+public static readonly StyledProperty<ProjectProfile> ProfileProperty =
+    AvaloniaProperty.Register<PumpStation2DControl, ProjectProfile>(nameof(Profile));
+
+public static readonly StyledProperty<IDictionary<string, float>> AnalogValuesProperty =
+    AvaloniaProperty.Register<PumpStation2DControl, IDictionary<string, float>>(nameof(AnalogValues));
+
+public static readonly StyledProperty<IDictionary<string, bool>> DigitalValuesProperty =
+    AvaloniaProperty.Register<PumpStation2DControl, IDictionary<string, bool>>(nameof(DigitalValues));
+
+// ViewModel 通过字典传值，不再绑定具体属性
+// AnalogValues = { "集水池.Level": 3.5, "1#泵.Current": 12.3, ... }
+// DigitalValues = { "1#泵.Run": true, "2#泵.Fault": false, ... }
+```
+
+#### 1.2 布局数据结构
+
+```csharp
+public class DeviceLayout
+{
+    public string DeviceId { get; set; }
+    public string DeviceType { get; set; }  // "Tank", "Pump", "Fan", "Valve"
+    public Rect Bounds { get; set; }        // 绘制区域
+    public Dictionary<string, object> Parameters { get; set; }  // 额外参数
+}
+
+public class LayoutResult
+{
+    public List<DeviceLayout> Devices { get; set; }
+    public List<(Point From, Point To)> Pipes { get; set; }  // 管道连接
+}
+```
+
+---
+
+### 阶段二：布局引擎（2 天）
+
+#### 2.1 布局策略接口
+
+```csharp
+public interface ILayoutEngine
+{
+    LayoutResult Calculate(ProjectProfile profile, Size canvasSize);
+}
+```
+
+#### 2.2 默认布局算法
+
+```
+输入：3 泵 + 1 池 + 0 风机
+输出：
+┌────────────────────────────────────┐
+│         [集水池]                    │  ← 顶部居中
+│            │                       │
+│    ┌───────┼───────┐               │
+│    │       │       │               │

+│════╪═══════╪═══════╪═══════════════│  ← 管道
+└────────────────────────────────────┘
+```
+
+```csharp
+public class DefaultLayoutEngine : ILayoutEngine
+{
+    public LayoutResult Calculate(ProjectProfile profile, Size canvasSize)
+    {
+        var devices = new List<DeviceLayout>();
+        var pipes = new List<(Point, Point)>();
+
+        // 1. 计算水箱位置（顶部居中）
+        var tankY = canvasSize.Height * 0.15;
+        var tankSpacing = canvasSize.Width / (profile.Tanks.Count + 1);
+        for (int i = 0; i < profile.Tanks.Count; i++)
+        {
+            devices.Add(new DeviceLayout
+            {
+                DeviceId = profile.Tanks[i].Name,
+                DeviceType = "Tank",
+                Bounds = new Rect(tankSpacing * (i + 1) - 40, tankY, 80, 120)
+            });
+        }
+
+        // 2. 计算泵位置（中部均分）
+        var pumpY = canvasSize.Height * 0.5;
+        var pumpSpacing = canvasSize.Width / (profile.Pumps.Count + 1);
+        for (int i = 0; i < profile.Pumps.Count; i++)
+        {
+            devices.Add(new DeviceLayout
+            {
+                DeviceId = profile.Pumps[i].Name,
+                DeviceType = "Pump",
+                Bounds = new Rect(pumpSpacing * (i + 1) - 30, pumpY, 60, 60)
+            });
+        }
+
+        // 3. 计算管道连接（水箱→泵→出水总管）
+        // ...
+
+        return new LayoutResult { Devices = devices, Pipes = pipes };
+    }
+}
+```
+
+#### 2.3 布局缓存
+
+```csharp
+// 只在 Profile 变化时重新计算布局
+partial void OnProfileChanged(ProjectProfile oldProfile, ProjectProfile newProfile)
+{
+    _cachedLayout = _layoutEngine.Calculate(newProfile, new Size(960, 540));
+    InvalidateVisual();
+}
+```
+
+---
+
+### 阶段三：渲染层改造（2 天）
+
+#### 3.1 复用现有 Renderer
+
+现有 `Controls/Renderers/` 目录已有：
+- `TankRenderer.cs`
+- `PumpRenderer.cs`
+- `FanRenderer.cs`
+- `ValveRenderer.cs`
+- `PipeRenderer.cs`
+
+只需修改调用方式：
+
+```csharp
+protected override void Render(DrawingContext context)
+{
+    if (_cachedLayout == null) return;
+
+    // 遍历布局结果，调用对应 Renderer
+    foreach (var device in _cachedLayout.Devices)
+    {
+        switch (device.DeviceType)
+        {
+            case "Tank":
+                var level = GetAnalogValue($"{device.DeviceId}.Level");
+                TankRenderer.Draw(context, device.Bounds, level);
+                break;
+            case "Pump":
+                var running = GetDigitalValue($"{device.DeviceId}.Run");
+                var fault = GetDigitalValue($"{device.DeviceId}.Fault");
+                PumpRenderer.Draw(context, device.Bounds, running, fault);
+                break;
+            // ...
+        }
+    }
+
+    // 绘制管道
+    foreach (var pipe in _cachedLayout.Pipes)
+    {
+        PipeRenderer.Draw(context, pipe.From, pipe.To);
+    }
+}
+```
+
+#### 3.2 值读取辅助方法
+
+```csharp
+private float GetAnalogValue(string key)
+{
+    return AnalogValues != null && AnalogValues.TryGetValue(key, out var v) ? v : 0f;
+}
+
+private bool GetDigitalValue(string key)
+{
+    return DigitalValues != null && DigitalValues.TryGetValue(key, out var v) && v;
+}
+```
+
+---
+
+### 阶段四：ViewModel 适配（1 天）
+
+#### 4.1 ProjectViewModel 暴露字典属性
+
+```csharp
+public partial class ProjectViewModel : ObservableObject
+{
+    [ObservableProperty]
+    private Dictionary<string, float> _analogValues = new();
+
+    [ObservableProperty]
+    private Dictionary<string, bool> _digitalValues = new();
+
+    private void OnDataUpdated(PlcDataModel data)
+    {
+        // 更新字典
+        foreach (var pump in _profile.Pumps)
+        {
+            AnalogValues[$"{pump.Name}.Current"] = data.GetAnalogRegister($"{pump.Name}.Current");
+            DigitalValues[$"{pump.Name}.Run"] = data.GetDigitalRegister($"{pump.Name}.Run");
+            DigitalValues[$"{pump.Name}.Fault"] = data.GetDigitalRegister($"{pump.Name}.Fault");
+        }
+
+        foreach (var tank in _profile.Tanks)
+        {
+            AnalogValues[$"{tank.Name}.Level"] = data.GetAnalogRegister($"{tank.Name}.Level");
+        }
+
+        // 触发 PropertyChanged
+        OnPropertyChanged(nameof(AnalogValues));
+        OnPropertyChanged(nameof(DigitalValues));
+    }
+}
+```
+
+#### 4.2 ViewA 绑定调整
+
+```xml
+<!-- 当有项目档案时，显示动态 2D 视图 -->
+<controls:PumpStation2DControl
+    Profile="{Binding ProjectView.Profile}"
+    AnalogValues="{Binding ProjectView.AnalogValues}"
+    DigitalValues="{Binding ProjectView.DigitalValues}"
+    IsVisible="{Binding HasProject}"/>
+```
+
+---
+
+### 阶段五：交互与动画（1 天）
+
+#### 5.1 点击事件
+
+```csharp
+// 设备点击 → 弹出操作面板
+protected override void OnPointerPressed(PointerPressedEventArgs e)
+{
+    var pos = e.GetPosition(this);
+    var device = _cachedLayout?.Devices.FirstOrDefault(d => d.Bounds.Contains(pos));
+    if (device != null)
+    {
+        // 触发命令
+        DeviceClickedCommand?.Execute(device.DeviceId);
+    }
+}
+
+public static readonly StyledProperty<ICommand> DeviceClickedCommandProperty = ...;
+```
+
+#### 5.2 动画效果

+- 泵运行时叶轮旋转（复用 `PumpControl` 的动画逻辑）
+- 管道流动虚线动画（复用 `PipeLineControl`）
+- 故障设备红色闪烁

+
+```csharp
+// 检测是否传入固定属性（旧用法）
+if (Tank1Level > 0 || Pump1Running)
+{
+    // 回退到硬编码布局（兼容旧代码）
+    DrawLegacyLayout(context);
+}
+else if (Profile != null)
+{
+    // 使用动态布局
+    DrawDynamicLayout(context);
+}
+```
+

+
+## 任务分解
+
+| # | 任务 | 预估 | 依赖 |
+|---|------|------|------|
+| 1 | 定义动态属性 + 布局数据结构 | 0.5 天 | 无 |
+| 2 | 实现 ILayoutEngine + DefaultLayoutEngine | 1.5 天 | #1 |
+| 3 | 改造 Render() 使用 Renderer | 1 天 | #1, #2 |
+| 4 | ProjectViewModel 暴露字典属性 | 0.5 天 | 无 |
+| 5 | ViewA 绑定调整 | 0.5 天 | #3, #4 |
+| 6 | 点击事件 + 操作面板 | 0.5 天 | #5 |
+| 7 | 动画效果（泵旋转/管道流动） | 0.5 天 | #3 |
+| 8 | 向后兼容处理 | 0.5 天 | #3 |
+| 9 | 单元测试 | 0.5 天 | #2 |
+| **总计** | | **~6 天** | |
+
+---
+
+## 风险与注意事项
+
+1. **布局算法复杂度**：不同泵站拓扑差异大（单池/多池、串联/并联），需要多种布局策略
+2. **性能**：设备数量很多时（>50），需要优化渲染（裁剪、缓存）
+3. **动画同步**：多个泵的旋转动画需要独立计时器
+4. **触控适配**：工业触摸屏需要大点击区域（≥ 40×40 px）
+
+---
+
+## 是否必要？
+
+**当前方案（ProjectView 卡片布局）已能满足扬杰二厂需求。**
+
+只有以下场景才需要动态 2D 工艺流程图：
+- 客户坚持要"仿真图"风格的界面
+- 需要在一个画面展示整个泵站拓扑关系
+- 有大屏展示需求（需要直观的工艺流程）
+
+如果以上都不需要，**维持现状即可**，不必投入 6 天开发。
+
+---
+
+## 替代方案
+
+如果只需简单的动态流程图，可以用 SVG/Canvas 方案：
+- 在 JSON 中定义流程图 SVG 模板
+- 运行时替换 SVG 中的变量（液位、状态）
+- 无需自定义控件，开发量更小（~2 天）

+# Elsa Workflows 集成说明
+
+## 问题背景
+
+YZWater3 项目需要集成工作流引擎来实现工艺流程编排。经过评估，选择了 Elsa Workflows 作为候选方案。
+
+## 遇到的问题
+
+### 1. API 不兼容
+
+安装 `Elsa.Workflows.Core 3.7.1` 后，发现以下命名空间不存在：
+- `Elsa.Workflows.Contracts`
+- `Elsa.Workflows.Runtime`
+- `Elsa.Workflows.Runtime.Messages`
+
+### 2. 需要完整的 DI 容器
+
+Elsa 3.x 需要完整的依赖注入容器配置，不适合直接在桌面应用中使用。
+
+### 3. 需要额外的 NuGet 包
+
+完整功能需要安装：
+- `Elsa.Workflows.Core`
+- `Elsa.Workflows.Runtime`
+- `Elsa.Activities.Console`
+- `Elsa.Activities.Http`
+- 等...
+
+## 当前解决方案
+
+### 简化版工作流服务
+
+创建了自定义的 `WorkflowService`，提供基本的工作流功能：
+
+```csharp
+// 初始化
+await WorkflowService.Instance.InitializeAsync();
+
+// 执行工作流
+var result = await WorkflowService.Instance.ExecuteWorkflowAsync("WastewaterTreatment", context);
+
+// 注册自定义工作流
+WorkflowService.Instance.RegisterWorkflow("MyWorkflow", definition);
+```
+
+### 工作流定义
+
+```csharp
+var workflow = new WorkflowDefinition
+{
+    Name = "污水处理流程",
+    Description = "自动检测液位、流量，控制泵启停",
+    Steps = new List<WorkflowStep>
+    {
+        new() { Name = "CheckTankLevel", Action = CheckTankLevel },
+        new() { Name = "CheckFlowRate", Action = CheckFlowRate },
+        new() { Name = "ControlPump", Action = ControlPump }
+    }
+};
+```
+
+## 完整 Elsa 集成方案（未来参考）
+
+### 所需 NuGet 包
+
+```xml
+<PackageReference Include="Elsa.Workflows.Core" Version="3.7.1" />
+<PackageReference Include="Elsa.Workflows.Runtime" Version="3.7.1" />
+<PackageReference Include="Elsa.Activities.Console" Version="3.7.1" />
+<PackageReference Include="Microsoft.Extensions.DependencyInjection" Version="8.0.0" />
+```
+
+### 配置代码
+
+```csharp
+using Elsa.Extensions;
+using Microsoft.Extensions.DependencyInjection;
+
+var services = new ServiceCollection();
+
+services.AddElsa(elsa =>
+{
+    elsa.AddActivitiesFrom<Program>();
+    elsa.UsePersistence(new MemoryWorkflowStateProvider());
+});
+
+var serviceProvider = services.BuildServiceProvider();
+```
+
+### 执行工作流
+
+```csharp
+using var scope = serviceProvider.CreateScope();
+var workflowRunner = scope.ServiceProvider.GetRequiredService<IWorkflowRunner>();
+var workflow = new Workflow(new Sequence { ... });
+var result = await workflowRunner.RunAsync(workflow);
+```
+
+## 替代方案
+
+如果未来需要更强大的工作流引擎，可以考虑：
+
+1. **WorkflowCore** - 更轻量，API 更简单
+2. **CoreWF** - .NET Workflow Foundation 的移植版
+3. **自建简单状态机** - 对于简单场景足够
+
+## 总结
+
+当前使用简化版工作流服务满足基本需求。如果未来需要：
+- 工作流持久化
+- 可视化设计器
+- 复杂分支/并行执行
+- 与外部系统集成
+
+建议重新评估 Elsa Workflows 的完整集成方案，或考虑替代方案。

+- 包含默认账户信息和安全提示
+
+### #3 ViewEViewModel 修复
+
+**发现的问题**：
+- `TechStack` 属性显示 "Avalonia UI 11 | .NET 8 | FreeSql | HslCommunication"，实际已迁移到 Avalonia 12 + SqlSugar
+- `OpenWebsite()` 方法为空
+- `CheckUpdateAsync()` 仅 `await Task.Delay(1000)`，假功能
+
+**修改内容**：
+- 更新 TechStack 为 "Avalonia UI 12 | .NET 8 | SqlSugar | HslCommunication"
+- 实现 `OpenWebsite()` 使用 `Process.Start` 打开公司官网
+- 实现 `CheckUpdateAsync()` 调用 `OpenWebsite()`
+
+### #4 Converter ConvertBack 修复
+
+**发现的问题**：
+- `BoolToBrushConverter`、`AlarmToBrushConverter`、`DeviceStatusToBrushConverter` 的 `ConvertBack` 抛出 `NotImplementedException`
+- 虽然当前仅用于单向绑定，但异常可能在不期望时触发
+
+**修改内容**：
+- 三个 ConvertBack 均改为 `return value;`（返回原值，不抛异常）
+- 添加注释说明仅支持单向绑定
+
+### #5 空 catch 块修复
+
+**发现的问题**：
+- `HubServer.cs:109`、`HubClient.cs:83`、`HubClient.cs:374` 有 3 处 `catch { }` 完全静默

+
+**修改内容**：
+- 将 6 个 `Header="..."` 改为 `Header="{Binding ...HeaderText}"`
+- 确认 LanguageService 中所有 key 的中英文翻译均存在
+
+### #7 DRY 消除重复默认值
+
+**发现的问题**：
+- `ConfigService.LoadConfig()` 创建默认配置时硬编码了 6 个默认值
+- 这些默认值与 `SystemConfig` 字段初始化器重复
+
+**修改内容**：
+- `ConfigService.LoadConfig()` 中改为 `new SystemConfig()`，默认值由模型自身提供
+
+### #8 登录失败锁定
+
+**发现的问题**：
+- AuthService 无登录失败次数限制，存在暴力破解风险
+
+**修改内容**：

+- 连续失败 5 次后锁定 15 分钟
+- 锁定期满自动解锁
+- 登录成功后清除失败记录
+- 添加 `AccountLocked` 国际化 key（中/英文）
+- 所有失败路径（用户不存在/账户禁用/密码错误）均记录失败次数
+
+### #9 单元测试补充
+
+**发现的问题**：
+- 测试覆盖率 <5%，仅 16 个测试，覆盖 HubMessage/User/WinSize
+- 所有核心服务无测试
+
+**修改内容**：
+- 新增 `AuthPasswordTests.cs`：9 个测试（哈希格式/唯一性/正确密码/错误密码/null/空/无效格式/空密码/中文密码）
+- 新增 `SystemConfigTests.cs`：8 个测试（PLC 默认值/字符串默认值/Hub 默认值/UI 默认值/地址字典/轮询间隔）
+- 测试总数从 16 增加到 **33**
+
+### #10 残留目录清理
+
+**发现的问题**：
+- 根目录下 9 个 `.buildcheck-*` 调试残留目录
+
+**修改内容**：
+- 删除全部 9 个目录：`.buildcheck`, `.buildcheck-3d-layout`, `.buildcheck-3d-refine`, `.buildcheck-exit`, `.buildcheck-layout`, `.buildcheck-pumpstation`, `.buildcheck-shutdown`, `.buildcheck-solid-3d`, `.buildcheck-ui`
+
+---
+
+## 编译验证
+
+每个任务完成后均执行 `dotnet build`，全部 **0 个错误**。
+
+```
+dotnet build → 0 个错误，156 个警告（均为已有的 nullable 警告）
+dotnet test  → 33 个测试全部通过
+```
+
+---
+
+## 仍待改进（未在本次执行中处理）
+
+| 项目 | 优先级 | 说明 |
+|------|--------|------|
+| CI/CD 流水线 | P1 | 添加 GitHub Actions 自动构建+测试 |

+{
+    var needsAnimation = AnyPumpRunning || Fan1Running || Fan2Running
+        || IsInflowRunning || IsOutflowRunning;
+    if (needsAnimation)
+    {
+        _phase = (_phase + 1) % 360;
+        if (AnyPumpRunning) _pumpAngle = (_pumpAngle + 4) % 360;
+        if (Fan1Running || Fan2Running) _fanAngle = (_fanAngle + 6) % 360;
+        InvalidateVisual();
+    }
+    return true;
+}, TimeSpan.FromMilliseconds(33));
+```
+
+**收益**: 静止画面 CPU 占用降低 80%+
+
+#### 任务2: PumpStation3DControl 定时器优化

+
+#### 任务5: MainViewModel 事件处理器泄漏
+**文件**: `MainViewModel.cs`, `ViewB~FViewModel.cs`
+
+**问题**: `Dispose()` 只释放 ViewA 和 Project ViewModel，ViewB~F 未释放
+
+**修复**:
+1. 为 ViewB~ViewF 添加 `IDisposable` 实现
+2. 每个 ViewModel 在 Dispose 中取消订阅 `LanguageChanged`、`DataUpdated`、`AlarmRaised` 等事件
+3. ViewE 将匿名 lambda 提取为命名方法 `OnLanguageChanged` 以便取消订阅
+4. `MainViewModel.Dispose()` 补全所有子 ViewModel 的释放调用
+
+**收益**: 防止内存持续增长，登出/重登录时正确清理
+
+#### 任务6: ViewAViewModel 事件处理
+**文件**: `ViewAViewModel.cs`
+
+**结论**: 代码分析发现 `MainWindow.OnClosed` 已正确处理 `DataContext` 的释放，当窗口关闭时会自动调用 `MainViewModel.Dispose()`，进而释放所有子 ViewModel。当前架构下该问题已被妥善处理，无需额外修改。
+
+#### 任务7: 数据库 N+1 查询
+**文件**: `DataLoggingService.cs`
+
+**问题**: 恢复设备运行小时数时全表加载 `EquipmentStatus` 再 GroupBy
+
+**修复**: 使用 `GroupBy + AggregateMax(Id)` 两阶段查询：
+```csharp
+var latestIds = db.Queryable<EquipmentStatus>()
+    .GroupBy(s => s.DeviceId)
+    .Select(s => SqlFunc.AggregateMax(s.Id))
+    .ToList();
+var latestByDevice = latestIds.Count > 0
+    ? db.Queryable<EquipmentStatus>().Where(s => latestIds.Contains(s.Id)).ToList()
+    : new List<EquipmentStatus>();
+```
+
+**收益**: 避免全表加载到内存，仅取每个设备最新记录
+
+#### 任务8: 数据库索引缺失
+**文件**: `DatabaseService.cs`
+
+**问题**: 表创建时未定义索引
+
+**修复**: 添加 `CreateIndexes()` 方法，在表初始化后创建 6 个索引：
+```csharp
+"CREATE INDEX IF NOT EXISTS idx_flow_record_time ON flow_records(RecordTime)",
+"CREATE INDEX IF NOT EXISTS idx_alarm_time ON alarm_records(AlarmTime)",
+"CREATE INDEX IF NOT EXISTS idx_equip_device_id ON equipment_status(DeviceId)",
+"CREATE INDEX IF NOT EXISTS idx_equip_update_time ON equipment_status(LastUpdateTime)",
+"CREATE INDEX IF NOT EXISTS idx_analog_record_time ON analog_records(RecordTime)",
+"CREATE INDEX IF NOT EXISTS idx_analog_tag_name ON analog_records(TagName)"
+```
+
+**收益**: 查询性能显著提升，尤其对时间范围查询
+
+#### 任务9: PLC 读取并发限制
+**文件**: `PlcPollingService.cs`
+
+**问题**: 项目档案模式下逐点读取，20 个模拟量 = 20 次网络请求同时并发
+
+**修复**: 添加 `SemaphoreSlim(4, 4)` 限制 PLC 读取并发数：
+```csharp
+private static readonly SemaphoreSlim _plcReadSemaphore = new(4, 4);
+// 每个读取任务先 WaitAsync，完成后 Release
+```
+
+**收益**: 防止同时发起过多请求导致 PLC 过载
+
+**备注**: 完整的批量读取优化（按地址分组）需要实现 PLC 地址解析器，已添加 TODO 注释。
+
+### 🟢 低优先级
+
+#### 任务10: ViewModel 过度属性通知
+**文件**: `ViewAViewModel.cs`
+
+**问题**: 每次 PLC 更新（1Hz）触发 30+ 个 PropertyChanged，不管值是否变化
+
+**修复**: 添加 `UpdateIfChanged<T>` 辅助方法，使用 `Object.Equals` 比较新旧值，仅在值变化时赋值和通知：
+```csharp
+private bool UpdateIfChanged<T>(ref T field, T newValue, string? propertyName = null)
+{
+    if (!Equals(field, newValue))
+    {
+        field = newValue;
+        OnPropertyChanged(propertyName);
+        return true;
+    }
+    return false;
+}
+```
+
+**收益**: 减少 PropertyChanged 事件和 UI 绑定更新，降低 UI 线程压力
+
+#### 任务11: WebSocket MemoryStream 分配
+**文件**: `HubServer.cs`, `HubClient.cs`
+
+**问题**: 每条消息 `new MemoryStream()` + `new byte[65536]`
+
+**修复**: 使用 `ArrayPool<byte>.Shared` 复用缓冲区，`MemoryStream` 通过 `SetLength(0)` 复用：
+```csharp
+var buffer = ArrayPool<byte>.Shared.Rent(65536);
+var messageBuffer = new MemoryStream();
+// ... 每条消息 messageBuffer.SetLength(0) 清空复用
+// finally 中 ArrayPool<byte>.Shared.Return(buffer)
+```
+
+**收益**: 大幅减少内存分配和 GC 压力
+
+#### 任务12: 日志优化
+**文件**: `LogService.cs`
+
+**问题**: Debug 级别过高 + 同步文件写入
+
+**修复**:
+1. 最低日志级别从 `Debug` 改为 `Information`
+2. 添加 `Microsoft`/`System` 框架日志覆盖为 `Warning`
+3. 文件写入添加 `buffered: true` 启用缓冲
+4. 添加 `retainedFileCountLimit: 30` 限制保留天数
+
+**收益**: 减少日志 IO，降低磁盘占用

+将"泵频率设置"的 `Border`（第 80-95 行）中的 `Grid.Row="1"` 改为 `Grid.Row="1"`（保持不变），但将 `Margin` 从 `"0,4,4,0"` 改为 `"0,4,4,4"`。
+
+- [ ] **Step 3: 将"操作按钮"移到 Row 2**
+
+将"操作按钮"的 `Border`（第 97-108 行）中的 `Grid.Row="1"` 改为 `Grid.Row="2"`，`Margin` 从 `"4,4,0,0"` 改为 `"4,4,0,4"`。
+
+- [ ] **Step 4: 在 Row 1 Column 1 添加系统设置区块**
+
+在"泵频率设置" `Border`（第 95 行 `</Border>`）之后，"操作按钮" `Border` 之前，插入：

+# 开机自启动功能设计
+
+## 概述
+
+为 YZWater3 添加跨平台（Windows/Linux/macOS）开机自启动功能。用户可在参数设置页面（ViewB）切换开关，开启后应用随系统启动自动运行。
+
+## 设计决策
+
+| 决策 | 选择 | 理由 |
+|------|------|------|
+| 启动行为 | 仍显示登录窗口 | 保持安全性，不自动登录 |
+| UI 位置 | ViewB 参数设置页面 | 与其他配置项在一起 |
+| 实现方案 | 单服务 + 平台检测 | 代码集中，改动少，符合项目风格 |
+| 平台支持 | Windows/Linux/macOS | 项目已支持三平台 |
+
+## 架构
+
+### 数据流
+
+```
+用户切换开关 → ViewBViewModel.RunAtStartup setter
+  → StartupService.SetAutoStart(value)     // 操作注册表/autostart/LaunchAgent
+  → ConfigService.GetConfig().RunAtStartup = value  // 持久化到 JSON
+  → ConfigService.SaveConfig()
+```
+
+### 涉及文件
+
+| 层级 | 文件 | 改动 |
+|------|------|------|
+| Model | `src/YZWater.Core/Models/SystemConfig.cs` | 新增 `RunAtStartup` 属性 |
+| Service | `src/YZWater.Core/Services/StartupService.cs` | 新建，跨平台开机自启动管理 |
+| ViewModel | `src/YZWater.Core/ViewModels/ViewBViewModel.cs` | 新增 `RunAtStartup` 属性 + 保存逻辑 |
+| View | `src/YZWater.Avalonia/Views/ViewB.axaml` | 新增 ToggleSwitch 控件 |
+| csproj | `src/YZWater.Core/YZWater.Core.csproj` | 添加 `Microsoft.Win32.Registry` 包引用 |
+
+## 详细设计
+
+### 1. SystemConfig 模型
+
+新增属性：
+
+```csharp
+[ObservableProperty] private bool _runAtStartup;
+```
+
+### 2. StartupService
+
+```csharp
+public static class StartupService
+{
+    private const string AppName = "YZWater";
+    
+    public static bool SetAutoStart(bool enabled)
+    public static bool IsAutoStartEnabled()
+    private static string GetExecutablePath()
+    
+    // 平台特定实现
+    private static bool SetWindowsAutoStart(bool enabled)
+    private static bool SetLinuxAutoStart(bool enabled)
+    private static bool SetMacAutoStart(bool enabled)
+    
+    private static bool IsWindowsAutoStartEnabled()
+    private static bool IsLinuxAutoStartEnabled()
+    private static bool IsMacAutoStartEnabled()
+}
+```
+
+**各平台实现：**
+
+- **Windows**：操作注册表 `HKCU\Software\Microsoft\Windows\CurrentVersion\Run`
+- **Linux**：创建/删除 `~/.config/autostart/yzwater.desktop`
+- **macOS**：创建/删除 `~/Library/LaunchAgents/com.yxwater.yzwater.plist`
+
+**错误处理：**
+- 所有操作包裹 `try-catch`，失败记录日志并返回 `false`
+- 使用 `RuntimeInformation.IsOSPlatform()` 判断平台
+- 未知平台返回 `false`
+
+### 3. ViewBViewModel
+
+新增属性：
+
+```csharp
+[ObservableProperty] private bool _runAtStartup;
+```
+
+属性变更处理：
+
+```csharp
+partial void OnRunAtStartupChanged(bool value)
+{
+    var success = StartupService.SetAutoStart(value);
+    if (!success)
+    {
+        _runAtStartup = !value;  // 回滚
+        OnPropertyChanged(nameof(RunAtStartup));
+    }
+    else
+    {
+        var config = ConfigService.GetConfig();
+        if (config != null)
+        {
+            config.RunAtStartup = value;
+            ConfigService.SaveConfig();
+        }
+    }
+}
+```
+
+加载配置：
+
+```csharp
+private void LoadConfig()
+{
+    var config = ConfigService.GetConfig();
+    if (config != null)
+    {
+        // ... 现有代码
+        RunAtStartup = config.RunAtStartup;
+    }
+}
+```
+
+### 4. ViewB View
+
+添加 ToggleSwitch：
+
+```xml
+<StackPanel Orientation="Horizontal" Spacing="10" Margin="0,10">
+    <TextBlock Text="开机自启动：" VerticalAlignment="Center"/>
+    <ToggleSwitch IsChecked="{Binding RunAtStartup}"/>
+</StackPanel>
+```
+
+## 依赖
+
+- `Microsoft.Win32.Registry` NuGet 包（仅 Windows 平台需要，通过条件引用）
+
+## 测试要点
+
+1. Windows：启用后检查注册表 `HKCU\...\Run` 中是否有 YZWater 键
+2. Linux：启用后检查 `~/.config/autostart/yzwater.desktop` 文件是否存在且内容正确
+3. macOS：启用后检查 `~/Library/LaunchAgents/com.yxwater.yzwater.plist` 文件
+4. 跨平台：在非 Windows 平台上禁用时不应抛出异常
+5. 配置持久化：重启应用后开关状态是否正确恢复
+6. 错误处理：当注册表/文件操作失败时，UI 是否正确回滚

+# 定时器使用指南
+
+本项目支持通过 **Windows 计划任务** + **Claude CLI** 实现定时自动执行任务。
+
+## 原理
+
+```
+Windows 计划任务 (schtasks)
+  └─ 定时触发 run-tasks.bat
+       └─ 调用 claude -p "任务指令" --dangerously-skip-permissions
+            └─ Claude 自动执行任务并归档到 docs/
+```
+
+## 快速使用
+
+### 1. 创建定时任务
+
+```powershell
+# 创建 1 小时后执行的一次性任务
+$triggerTime = (Get-Date).AddHours(1).ToString("HH:mm")
+schtasks /create /tn "YZWater3-Tasks" /tr "E:\Source\YZWater3\scripts\run-tasks.bat" /sc once /st $triggerTime /f
+```
+
+### 2. 查看任务状态
+
+```powershell
+schtasks /query /tn "YZWater3-Tasks"
+```
+
+### 3. 立即手动触发
+
+```powershell
+schtasks /run /tn "YZWater3-Tasks"
+```
+
+### 4. 取消任务
+
+```powershell
+schtasks /delete /tn "YZWater3-Tasks" /f
+```
+
+### 5. 查看执行结果
+
+执行完成后，总结会写入 `docs/` 目录：
+- `docs/improvement-report-{date}.md` — 改进报告
+- `docs/config-reference.md` — 配置参考（如适用）
+
+## 自定义任务
+
+修改 `scripts/run-tasks.bat` 中的提示词即可执行不同任务：
+
+```batch
+@echo off
+chcp 65001 >nul
+cd /d E:\Source\YZWater3
+claude -p "你的任务描述..." --dangerously-skip-permissions
+```
+
+## 常用定时任务示例
+
+```powershell
+# 每天凌晨 2 点执行代码质量检查
+schtasks /create /tn "YZWater3-DailyCheck" /tr "E:\Source\YZWater3\scripts\daily-check.bat" /sc daily /st 02:00 /f
+
+# 每周一 9 点生成周报
+schtasks /create /tn "YZWater3-WeeklyReport" /tr "E:\Source\YZWater3\scripts\weekly-report.bat" /sc weekly /d MON /st 09:00 /f
+
+# 30 分钟后一次性执行
+$triggerTime = (Get-Date).AddMinutes(30).ToString("HH:mm")
+schtasks /create /tn "YZWater3-Quick" /tr "E:\Source\YZWater3\scripts\run-tasks.bat" /sc once /st $triggerTime /f
+```
+
+## 注意事项
+
+1. **电脑需要保持开机且已登录** — 计划任务在用户会话中运行
+2. **笔记本请接电源** — 默认电池模式下不启动
+3. **网络需连通** — Claude 需要调用 API
+4. **`--dangerously-skip-permissions`** — 跳过权限确认，适合自动化场景
+5. **执行过程会弹出命令行窗口** — 请勿手动关闭
+6. **任务执行完后可查看 `docs/` 目录中的报告**

+> 梳理日期：2026-09-06
+
+---
+
+## 一、项目概况
+
+| 项 | 值 |
+|---|---|
+| 工艺场景 | 扬杰二厂**集水池排污泵站**（1 个集水池 + 3 台排污泵） |
+| PLC | 西门子 S7（S7-200 Smart），地址 I/Q/M/VD |
+| 控制方式 | **中控（上位机）/ 屏控（现场触摸屏）二选一**，由 M\*.0 位决定 |
+| 监测量 | 液位、压力、流量、日流量、3 台泵电流、日台时 |
+| 前端模板 | `PumpStation`（泵站专用视图） |
+
+---
+
+## 二、核心业务流程
+
+### 1️⃣ 数据采集流程（每轮询周期，默认 1s）
+
+```
+PlcPollingService 定时轮询
+   │
+   ├─ 读模拟量 VD62(液位) / VD6600(压力) / VD6604(流量)
+   │         VD50/54/58(泵电流) / VD884(日流量) / VD950+VD10(日台时)
+   │
+   ├─ 读数字量 Q0.1~Q0.3(泵运行) / I0.1~I0.3(变频器故障) / M2.6/M5.6/M8.6(手自动)
+   │
+   ├─ 读控制参数 VD500/504/508/528/962(液位阈值) / VD6700/6704(压力阈值)
+   │
+   └─ 发布 DataUpdated 事件 → 触发下游所有业务
+        ├─ AlarmService       → 报警检测
+        ├─ AutoControlService  → 液位自动启停泵
+        ├─ DeviceStateMachineManager → 设备状态机转换
+        ├─ DataLoggingService  → 历史数据入库
+        └─ UI ViewModel       → 界面刷新
+```
+
+### 2️⃣ 控制模式判定（每台泵独立）
+
+```
+读 M*.0（中控/屏控选择位）
+   ├─ M*.0 = 0 → 中控模式：上位机启停命令【有效】
+   └─ M*.0 = 1 → 屏控模式：上位机【只监视】，写命令无效
+```
+
+### 3️⃣ 液位自动控制（核心业务，`AutoControlService`）
+
+```
+每个轮询周期:
+  读集水池液位 VD62
+       │
+       ▼
+  计算需要泵数 requiredCount:
+  ┌─────────────────────────────────────────────┐
+  │ 液位 > VD962(保护液位)  → 3台全启（紧急排污）│
+  │ 液位 > VD528(停止液位)  → 0台（全部停止）    │
+  │ 液位 < VD508(启3台位)   → 3台               │
+  │ 液位 < VD504(启2台位)   → 2台               │
+  │ 液位 < VD500(启1台位)   → 1台               │
+  │ 其余（滞后区间）        → 维持现状           │
+  └─────────────────────────────────────────────┘
+       │
+       ▼
+  防抖延迟:
+    启泵条件需持续 ≥ 3 秒 (StartDelaySeconds)
+    停泵条件需持续 ≥ 5 秒 (StopDelaySeconds)
+       │
+       ▼
+  选泵策略 (SelectPumpsToRun):
+    ① 剔除故障泵
+    ② 按日台时(累计运行时长)升序 → 优先选运行时间最短的泵
+    ③ 时长相同时用轮换索引打破平局（均衡磨损）
+       │
+       ▼
+  执行启停（对每台泵）:
+    目标开 & 未运行 & 无故障 & 距上次启动 ≥ 60秒
+        → 点动写 M*.3 (置ON 200ms → OFF)
+    目标关 & 运行中 & 距上次停止 ≥ 60秒
+        → 点动写 M*.4
+```
+
+**要点**：`requiredCount` 只在越限时变化，滞后区间防止液位在阈值附近抖动导致频繁启停。
+
+### 4️⃣ 手动控制流程（操作员在中控执行）
+
+```
+操作员点击 启动/停止 按钮 (ViewA / ProjectView)
+   │
+   ▼
+权限检查 (AuthService.HasPermission ≥ Operator)
+   │
+   ▼
+写入点动命令位: 启动 M*.3 / 停止 M*.4 (ON 200ms → OFF)
+   │  （命令是否生效取决于该泵当前是中控模式 M*.0=0）
+   ▼
+下一轮询周期读回 Q0.x 验证运行状态 → 界面刷新
+   │
+   └─ 审计日志记录 (AuditService.Log)
+```
+
+### 5️⃣ 报警流程
+
+```
+每周期 AlarmService.CheckAlarms:
+  ┌────────────────────────┬──────┬──────────────────────┐
+  │ 条件                    │ 级别 │ 动作                  │
+  ├────────────────────────┼──────┼──────────────────────┤
+  │ 压力 < VD6700(低压设定) │ 警告 │ 日志 + 界面提示       │
+  │ 压力 > VD6704(高压设定) │ 警告 │ 日志 + 界面提示       │
+  │ 泵变频器故障 I0.1~I0.3  │ 严重 │ 报警记录 + 通知       │
+  │ PLC 断连                │ 提示 │ PLC_Connection 报警   │
+  └────────────────────────┴──────┴──────────────────────┘
+       │
+       ├─ 报警延迟 3 秒 + 死区 2.0（防抖）
+       ├─ 通过 Channel 异步入库 alarm_records
+       ├─ 升级机制: 未确认超 10 分钟 → 升级 + 通知
+       └─ 操作员确认 → 更新 IsConfirmed/ConfirmedBy
+```
+
+### 6️⃣ 设备状态机流程（每台泵）
+
+```
+PLC 信号驱动 Stateless 状态机:
+  Q0.x 运行 + I0.x 无故障 → Running
+  Q0.x 停止 + 无故障      → Stopped
+  I0.x = 1 (变频器故障)   → Fault（触发设备报警）
+       │
+       └─ 状态每次变化持久化到 equipment_statuses 表
+```
+
+### 7️⃣ 数据统计与留存
+
+```
+持续: 轮询数据 → analog_records / flow_records（360天保留）
+每日: DataRetentionService 清理过期记录（24h 周期）
+每日: BackupService 启动备份 + 24h 定时备份（WAL checkpoint + VACUUM INTO）
+日台时: 读 VD950+VD10 等（PLC 累计），M19.4 点动清零
+日流量: 读 VD884，M19.3 点动复位
+```
+

+
+远程操作泵启停需要满足 **两级条件**，缺一不可：
+
+```
+第一步: 切换到「中控模式」

+  ModeSelectAddress = 1 → 屏控（现场控制，上位机只监视）
+       │
+       ▼
+第二步: 切换到「手动模式」
+  AutoStateAddress = 0 → 手动（允许远程启停）
+  AutoStateAddress = 1 → 自动（PLC 自动逻辑运行中，远程不可干预）
+       │
+       ▼
+   ✅ 可以操作泵启停

+
+## 六、数据采集流程
+
+```
+PlcPollingService 定时轮询 (默认 1s)
+   │
+   ├─ 读模拟量: VD62(液位) / VD6600(压力) / VD6604(流量)
+   │            VD50/54/58(泵电流) / VD7000(总流量)
+   │            VD950+VD10 / VD954+VD18 / VD958+VD28(日台时)
+   │
+   ├─ 读数字量: Q0.1-3(泵运行) / M17.1-3(泵过流)
+   │            M3.1/M6.1/M9.1(变频器故障)
+   │            M19.5(低液位报警) / M30.1(高压报警)
+   │            M1.0/M4.0/M7.0(中控/屏控) / M2.6/M5.6/M8.6(手自动)
+   │
+   ├─ 读控制参数: VD500/504/508/528/962(液位阈值)
+   │              VD6700/6704(压力阈值)
+   │
+   └─ 发布 DataUpdated 事件
+        ├─ AlarmService         → 报警检测 + 报警显示
+        ├─ ProjectViewModel     → UI 刷新 (模式显示、泵状态、液位趋势)
+        ├─ DataLoggingService   → 历史数据入库
+        └─ (AutoControlService  → 不激活，因 enableAutoControl=false)
+```
+
+**注意**: `AutoControlService` 在 `enableAutoControl=false` 时不会订阅 `DataUpdated`，不向 PLC 写入任何启停命令。
+
+---
+
+## 七、报警逻辑
+
+### 7.1 报警源
+
+| 报警类型 | 触发条件 | 来源 | 级别 |

+| PLC 断连 | 通信超时 | 上位机检测 | 紧急(4) |
+
+### 7.2 报警处理
+
+```
+报警触发 → 记录到 alarm_records 表 → UI 弹出 → 桌面通知
+   │
+   ├─ 确认: 操作员点击确认 → 标记 IsConfirmed
+   └─ 复位: 操作员点击复位 → 清除活跃状态 + 点动 M30.0 → PLC 侧复位报警输出
+```
+
+### 7.3 报警特性
+

+
+- **集水池**：显示当前液位和各级控制液位
+  - 即时液位：当前实际液位（m）
+  - 启泵1/2/3液位：启动对应数量泵的阈值
+  - 停泵液位：高于此值全部停止

+
+---
+
+## 液位自动控制
+
+> **本项目（扬杰二厂泵站）出厂即为"PLC 自动，上位机仅监控"**：泵组启停全部由 PLC 程序完成，
+> 上位机只负责显示、报警和记录，不会向 PLC 写启停指令。
+> 现场看到的"自动模式"按钮、泵组状态都只反映 PLC 的动作结果。
+>
+> 如果现场要求改成"上位机接管启停"，把 `projects/yangjie2.json` 里的
+> `control.enableAutoControl` 改为 `true` 后重启程序即可（下面的档位表就是这种情况下上位机执行的逻辑）。
+
+### 自动模式（上位机接管时的档位逻辑）
+
+| 液位条件 | 动作 |
+|----------|------|
+| 液位 < 启泵3液位 | 启动全部 3 台泵 |
+| 液位 < 启泵2液位 | 启动 2 台泵 |
+| 液位 < 启泵1液位 | 启动 1 台泵 |
+| 液位 > 停泵液位 | 全部停止 |
+| 液位 > 保护液位 | 紧急全启 + 报警 |
+
+- 判定按从上往下的顺序取第一条成立的条件，因此三个启泵液位必须满足 **启泵1 < 启泵2 < 启泵3**，
+  且都低于停泵液位，档位才不会互相盖掉。阈值填错程序不会拦，投运前需在画面核对一遍。
+- "保护液位"这一行是上位机自动控制时的动作（紧急全启），同时无条件产生一条紧急报警。
+  《扬杰二厂泵站需求》里对保护液位写的是"超限 → 紧急停机"，两者不一致 —— **以 PLC 程序为准，投运前需与厂家确认**。
+
+### 泵轮换
+
+上位机接管时启用泵轮换功能，优先启动运行时间较短的泵，均衡磨损。（PLC 自动控制时轮换由 PLC 程序决定，与上位机无关。）
+
+### 防频繁启停
+
+上位机接管时的保护参数：
+
+- 启泵延迟：3 秒
+- 停泵延迟：5 秒
+- 同一台泵最小间隔：60 秒
+
+---
+
+## 泵组操作
+
+### 中控/屏控模式
+
+- **中控模式**（M*.0 = 0）：上位机可远程操作
+- **屏控模式**（M*.0 = 1）：仅现场触摸屏操作，上位机只监视
+
+### 手动启停
+
+1. 确认处于中控模式
+2. 点击泵卡片上的「启动」或「停止」按钮
+3. 系统发送点动命令（200ms 脉冲）
+
+### 故障处理
+
+当泵显示「故障!」时：
+1. 查看故障状态区确认故障泵
+2. 到现场检查泵和变频器
+3. 故障排除后，系统自动恢复（故障信号消失后状态机自动转回停止）
+
+---
+
+## 报警处理
+
+### 报警类型
+
+| 类型 | 说明 | 级别 |
+|------|------|------|
+| 液位过高 | 超过保护液位 | 紧急 |
+| 液位过低 | 低于最低液位 | 警告 |
+| 压力过高 | 超过高压设定值 | 警告 |
+| 压力过低 | 低于低压设定值 | 警告 |
+| 泵故障 | 变频器故障信号 | 严重 |
+| PLC 断连 | 通信中断 | 警告 |
+
+### 报警确认
+
+1. 在「报警日志」页查看所有报警
+2. 选择报警记录，点击「确认」
+3. 填写处理备注
+
+### 报警通知
+
+系统支持以下通知方式（需在参数设置页配置）：
+- 系统托盘弹窗
+- 邮件通知（需配置 SMTP）
+
+---
+
+## 日台时管理
+
+### 查看日台时
+
+每台泵卡片显示当日累计运行时间（小时:分钟）。
+
+### 日台时清零
+
+3 台泵共用清零地址（M19.4），在泵组区底部点击「日台时清零」按钮统一清零。
+
+**建议**：每日早班交接时清零。
+
+---
+
+## 参数配置
+
+### 进入参数设置
+
+1. 点击顶部导航栏「参数」标签
+2. 需要工程师及以上权限
+
+### 项目档案切换
+
+1. 在「项目档案」区域选择项目
+2. 点击「保存配置」

+
+## 常见问题
+
+### Q: 泵无法远程启动？
+
+**检查**：
+1. 控制模式是否为「中控」（泵卡片显示「中控」）
+2. 泵是否有故障
+3. PLC 是否连接正常（顶部状态栏）
+
+### Q: 液位显示异常？
+
+**检查**：
+1. 液位传感器是否正常
+2. PLC 地址 VD62 是否正确
+3. 在参数设置页测试连接
+
+### Q: 自动控制不动作？
+
+**本项目出厂为"PLC 自动，上位机仅监控"，上位机本来就不写启停指令**，泵不启停请先查 PLC 程序和现场控制档位（中控/屏控）。
+只有把 `projects/yangjie2.json` 的 `control.enableAutoControl` 改成 `true` 后，上位机才会参与启停，这时按下面排查：
+
+1. 自动控制是否启用（本项目默认 **未** 启用）
+2. 日志里是否出现 `自动控制未启用: 项目 [...] 配置为 PLC 自动控制`
+3. 液位阈值设置是否合理：启泵1 < 启泵2 < 启泵3 且都低于停泵液位，填反了程序不会拦
+4. 查看日志文件 `Logs/log-*.txt` 确认控制逻辑
+
+### Q: 如何备份配置？
+
+1. 在参数设置页点击「导出配置」
+2. 选择保存路径
+3. 备份 `projects/` 目录下的项目文件
+
+### Q: 日台时不准？
+
+**处理**：
+1. 确认 PLC 程序中日台时累计逻辑正确
+2. 每日定时清零（可配合 Quartz 定时任务）

+## 四、液位控制参数
+
+| VD 地址 | 名称 | 方向 | 用途 |
+|---------|------|------|------|
+| VD62 | 即时液位 | 只读 | 当前集水坑液位 |
+| VD500 | 启动1台泵液位 | 读写 | 液位低于此值 → 启1台泵 |
+| VD504 | 启动2台泵液位 | 读写 | 液位低于此值 → 启2台泵 |
+| VD508 | 启动3台泵液位 | 读写 | 液位低于此值 → 启3台泵 |
+| VD528 | 停止液位 | 读写 | 液位高于此值 → 全部停止 |
+| VD962 | 保护液位 | 读写 | 超限 → 紧急停机 + 报警 |

+
+## 五、压力/流量参数
+
+| VD 地址 | 名称 | 方向 | 用途 |
+|---------|------|------|------|

+| VD6704 | 高压设置 | 读写 | 高压报警阈值 |
+| VD6604 | 即时流量 | 读 | 实时流量值 |
+
+---
+
+## 六、控制逻辑
+
+### 6.1 控制模式
+
+```
+M*.0 = 0 → 中控模式（上位机可远程操作）
+M*.0 = 1 → 屏控模式（仅现场触摸屏操作，上位机只监视）
+```
+
+> 中控模式下，上位机的启停命令才有效；屏控模式下上位只能监视状态。
+
+### 6.2 液位自动控制
+
+```
+液位变化趋势：
+    ↑ 保护液位 (VD962)  ───── 紧急停机 + 报警
+    │
+    ↑ 停止液位 (VD528)  ───── 全部泵停止
+    │
+    │ ↑ 启1台 (VD500)   ───── 启动 1 台泵
+    │ │
+    │ │ ↑ 启2台 (VD504) ───── 启动 2 台泵
+    │ │ │
+    │ │ │ ↑ 启3台 (VD508) ─── 启动 3 台泵
+    │ │ │ │
+```
+
+**启停逻辑**（液位从高到低）：
+
+| 条件 | 动作 |
+|------|------|
+| 液位 < VD508 | 启动第3台泵（共3台运行） |
+| 液位 < VD504 | 启动第2台泵（共2台运行） |
+| 液位 < VD500 | 启动第1台泵（共1台运行） |
+| 液位 > VD528 | 全部停止 |
+| 液位 > VD962 | 紧急停机 + 保护报警 |
+
+**防频繁启停**（建议）：
+- 启泵条件需持续 3 秒以上
+- 停泵条件需持续 5 秒以上
+- 同一台泵两次启动间隔 ≥ 60 秒
+
+### 6.3 报警逻辑
+
+| 条件 | 报警级别 | 动作 |
+|------|----------|------|
+| 压力 < VD6700 | 警告 | 记录日志 + 界面提示 |
+| 压力 > VD6704 | 警告 | 记录日志 + 界面提示 |
+| 液位 > VD962 | 严重 | 紧急停机 + 通知 |
+| 泵变频器故障 (I0.x) | 严重 | 停止对应泵 + 通知 |
+
+---
+
+## 七、与当前代码的差异分析
+
+| 维度 | 当前代码（默认配置） | 实际需求 | 适配工作量 |
+|------|---------------------|----------|-----------|
+| 泵数量 | 5台 | **3台** | 中（需改 PlcConfig + UI） |
+| 风机 | 2台 | **0台** | 低（移除或忽略） |
+| 水箱/液位 | 4个水箱 | **1个集水坑** | 中 |
+| 泵频率 | 5个频率读取 | **无** | 低（移除） |
+| 流量 | 进/出水流量 | **1个流量 + 日流量** | 中 |
+| 压力 | 无 | **压力 + 高低压报警** | 高（需新增） |
+| 电流 | 无 | **3台泵电流** | 高（需新增） |
+| 日台时 | 无 | **3台泵日台时** | 高（需新增） |
+| 控制模式 | 无 | **中控/屏控切换** | 高（需新增） |
+| 自动控制 | 无 | **多级液位自动启停** | 高（核心逻辑） |
+
+---
+
+## 八、需要开发的功能点
+
+### P0 — 核心功能
+
+1. **PLC 地址重映射** — 按实际 VD/M/I/Q 地址配置 PlcConfig
+2. **液位自动控制逻辑** — 多级启停泵 + 保护液位 + 防频繁启停
+3. **中控/屏控切换** — 中控模式下才允许远程操作
+
+### P1 — 监测功能
+
+4. **压力监测** — 实时显示 + 高低压报警
+5. **泵电流监测** — 实时曲线 + 过载报警
+6. **3台泵状态** — 运行/停止/故障/手自动状态
+
+### P2 — 统计功能
+
+7. **日台时统计** — 读取 PLC 累计值 + 每日清零 + 报表
+8. **日流量统计** — 读取 VD884 + 历史曲线
+
+---
+
+## 九、待确认事项
+
+| # | 问题 | 影响 |
+|---|------|------|
+| 1 | 泵2/泵3 的"手自动状态"位含义是否与泵1一致？（泵1: 1=自动, 泵2/3: 1=手动） | 控制逻辑 |
+| 2 | 3台泵是否需要考虑轮换运行（均衡磨损）？ | 自动控制策略 |
+| 3 | "点动"命令的持续时间是多少毫秒？ | 写入逻辑 |
+| 4 | 保护液位触发后，是否需要人工确认才能恢复？ | 安全逻辑 |
+| 5 | 日台时清零是每天固定时间还是手动触发？ | 统计逻辑 |
+| 6 | 是否有备用泵的概念（某台泵故障时自动切换）？ | 可靠性 |

+
+## 授权配置
+
+HslCommunication 是商业授权库，使用前需要设置授权码。
+
+### 授权方式
+
+| 方式 | 说明 |
+|------|------|
+| 免费试用 | 不设置授权码，功能受限（随机断开、部分 API 不可用） |
+| 正式授权 | 购买授权码后通过 `SetAuthorizationCode()` 激活 |
+
+### 设置授权码
+
+**必须在创建 PLC 通信对象之前调用**，建议在程序启动入口（如 `Main()` 或 `App.OnStartup()`）中调用：
+
+```csharp
+using HslCommunication;
+
+// 在程序启动时设置授权码（必须在使用任何 PLC 功能之前调用）
+HslCommunication.Authorization.SetAuthorizationCode("你的授权码");
+```
+
+### 在 Avalonia 中的应用示例
+
+```csharp
+// App.axaml.cs
+public class App : Application
+{
+    public override void OnFrameworkInitializationCompleted()
+    {
+        // 激活 HslCommunication 授权（在所有 PLC 操作之前）
+        HslCommunication.Authorization.SetAuthorizationCode(
+            "c765bac7-2caf-446d-9619-f67e19d6624e");
+
+        // 后续初始化...
+        base.OnFrameworkInitializationCompleted();
+    }
+}
+```
+
+### 在 WPF / WinForms 中的应用示例
+
+```csharp
+// Program.cs 或 App.xaml.cs
+[STAThread]
+static void Main()
+{
+    // 在 Application 启动前设置
+    HslCommunication.Authorization.SetAuthorizationCode("你的授权码");
+
+    App domain = new App();
+    domain.InitializeComponent();
+    domain.Run();
+}
+```
+
+### 授权相关 API
+
+```csharp
+// 检查授权状态
+bool isAuthorized = HslCommunication.Authorization.IsAuthorized();
+
+// 获取授权到期时间
+DateTime expireDate = HslCommunication.Authorization.GetExpireDate();
+
+// 获取授权设备数量限制
+int deviceCount = HslCommunication.Authorization.GetDeviceCount();
+```
+
+### 未授权时的表现
+
+- 连接会随机断开（不定时丢失连接）
+- 部分高级功能不可用
+- 数据读取可能出现异常
+
+> **注意**：本项目使用的授权码 `c765bac7-2caf-446d-9619-f67e19d6624e` 仅限本项目使用。  
+> 其他项目请前往 [HslCommunication 官网](https://www.hslcommunication.cn/) 购买授权。

+
+## 数据读取
+
+### 读取浮点数（REAL）
+
+```csharp
+/// <summary>
+/// 读取浮点数 (4字节 REAL)
+/// </summary>
+public async Task<float> ReadFloatAsync(string address)
+{
+    if (!_isConnected || _plc == null) return 0f;

+```
+
+### 读取布尔值（位）

+    
+    var result = await _plc.ReadBoolAsync(address);   // 如 "M10.0"
+    return result.IsSuccess ? result.Content : false;
+}
+```
+
+### 批量读取字节（高性能）
+
+```csharp
+/// <summary>
+/// 批量读取字节数组
+/// </summary>
+public async Task<byte[]?> ReadBytesAsync(string address, ushort length)
+{
+    if (!_isConnected || _plc == null) return null;
+    
+    var result = await _plc.ReadAsync(address, length);  // 如 "V100", 20
+    return result.IsSuccess ? result.Content : null;
+}
+
+// 使用示例：一次读取 5 个连续的浮点数
+var bytes = await ReadBytesAsync("V100", 20);  // 从 V100 开始读 20 字节
+if (bytes != null)
+{
+    var value1 = ParseFloat(bytes, 0);   // VD100
+    var value2 = ParseFloat(bytes, 4);   // VD104
+    var value3 = ParseFloat(bytes, 8);   // VD108
+    var value4 = ParseFloat(bytes, 12);  // VD112
+    var value5 = ParseFloat(bytes, 16);  // VD116
+}
+```
+
+### 读取整数类型
+
+```csharp
+/// <summary>
+/// 读取整数（INT/WORD/DINT/DWORD）
+/// </summary>
+public async Task<int> ReadIntAsync(string address, string dataType = "INT")
+{
+    if (!_isConnected || _plc == null) return 0;
+    
+    ushort length = dataType switch
+    {
+        "INT" or "WORD" => 2,
+        "DINT" or "DWORD" => 4,
+        _ => 2
+    };
+    
+    var result = await _plc.ReadAsync(address, length);
+    if (!result.IsSuccess || result.Content == null) return 0;
+    
+    var bytes = result.Content;
+    if (BitConverter.IsLittleEndian)
+    {
+        Array.Reverse(bytes);
+    }
+    
+    return dataType switch
+    {
+        "INT" => BitConverter.ToInt16(bytes, 0),
+        "WORD" => BitConverter.ToUInt16(bytes, 0),
+        "DINT" => BitConverter.ToInt32(bytes, 0),
+        "DWORD" => (int)BitConverter.ToUInt32(bytes, 0),
+        _ => 0
+    };
+}
+```
+
+---
+
+## 数据写入
+
+### 写入浮点数
+
+```csharp
+/// <summary>
+/// 写入浮点数
+/// </summary>
+public async Task<bool> WriteFloatAsync(string address, float value)
+{
+    if (!_isConnected || _plc == null) return false;
+    
+    var result = await _plc.WriteAsync(address, value);  // 如 "VD100", 123.45f
+    return result.IsSuccess;
+}
+```
+
+### 写入布尔值
+
+```csharp
+/// <summary>
+/// 写入布尔值
+/// </summary>
+public async Task<bool> WriteBoolAsync(string address, bool value)
+{
+    if (!_isConnected || _plc == null) return false;
+    
+    var result = await _plc.WriteAsync(address, value);  // 如 "M10.0", true
+    return result.IsSuccess;
+}
+```
+
+### 写入整数
+
+```csharp
+/// <summary>
+/// 写入整数
+/// </summary>
+public async Task<bool> WriteIntAsync(string address, int value, string dataType = "INT")
+{
+    if (!_isConnected || _plc == null) return false;
+    
+    object data = dataType switch
+    {
+        "INT" => (short)value,
+        "WORD" => (ushort)value,
+        "DINT" => value,
+        "DWORD" => (uint)value,
+        _ => (short)value
+    };
+    
+    var result = await _plc.WriteAsync(address, data);
+    return result.IsSuccess;
+}
+```
+
+---
+
+## 字节序处理
+
+**重要**：西门子 S7 PLC 使用 **大端序（Big-Endian）**，而 Windows 使用 **小端序（Little-Endian）**，读取字节后需要进行转换。
+
+### 浮点数解析
+
+```csharp
+/// <summary>
+/// 从字节数组解析浮点数（S7 大端序 → 本地小端序）
+/// </summary>
+public static float ParseFloat(byte[] data, int offset)
+{
+    if (data == null || offset + 4 > data.Length) return 0f;
+    
+    if (BitConverter.IsLittleEndian)
+    {
+        // S7 是大端序，需要翻转字节
+        var bytes = new byte[] { 
+            data[offset + 3], data[offset + 2], 
+            data[offset + 1], data[offset] 
+        };
+        return BitConverter.ToSingle(bytes, 0);
+    }
+    return BitConverter.ToSingle(data, offset);
+}
+```
+
+### 位解析
+
+```csharp
+/// <summary>
+/// 从字节中提取特定位
+/// </summary>
+public static bool ParseBit(byte[] data, int byteOffset, int bitOffset)
+{
+    if (data == null || byteOffset >= data.Length) return false;
+    return (data[byteOffset] & (1 << bitOffset)) != 0;
+}
+```
+
+---
+
+## 地址配置管理 PlcConfig
+
+将所有 PLC 地址集中管理，支持从配置文件覆盖，避免硬编码散落各处。
+
+```csharp
+using System.Text.Json;
+
+/// <summary>
+/// PLC 地址配置 - 所有地址映射集中管理，支持配置文件覆盖
+/// </summary>
+public static class PlcConfig
+{
+    // 地址覆盖表（从配置文件加载）
+    private static Dictionary<string, string> _overrides = new();
+
+    /// <summary>

+    {
+        if (File.Exists(configPath))

+
+### 关键机制说明
+
+| 机制 | 实现方式 | 说明 |
+|------|----------|------|
+| **并发控制** | `SemaphoreSlim(4, 4)` | 限制同时发起的 PLC 读取请求数，防止 PLC 过载 |
+| **死区过滤** | `ApplyWithDeadband()` | 数据变化小于阈值（默认 0.5%）时不更新，减少 UI 无效刷新 |
+| **降级模式** | `isInDegradedMode` | 连接失败超过 `MaxReconnectAttempts` 次后进入，重试间隔从 1s 延长到 30s |
+| **指数退避** | `ReconnectBaseDelayMs * attempts` | 重连间隔逐步增加，上限 30s，避免频繁冲击 PLC |
+| **并行批量读取** | `Task.WhenAll()` | 多个地址段并行发起读取，充分利用网络带宽 |
+
+---
+
+## 地址格式参考
+
+### 存储区域
+
+| 区域 | 说明 | 地址前缀 |
+|------|------|----------|
+| V | 变量存储区（Variable） | `V` / `VB` / `VW` / `VD` |
+| M | 标志位（Marker） | `M` / `MB` / `MW` / `MD` |
+| I | 输入映像区（Input） | `I` / `IB` / `IW` / `ID` |
+| Q | 输出映像区（Output） | `Q` / `QB` / `QW` / `QD` |
+
+### 数据类型与地址格式
+
+| 数据类型 | 字节长度 | 地址格式示例 | 说明 |
+|----------|----------|--------------|------|
+| Bool（位） | 1 bit | `M10.0`, `Q0.5` | 字节偏移.位索引 |
+| Byte | 1 | `VB100`, `MB10` | 单字节 |
+| Word/INT | 2 | `VW100`, `MW10` | 16位整数 |
+| DWord/REAL | 4 | `VD100`, `MD10` | 32位浮点数 |
+| DWord/DINT | 4 | `VD100`, `MD10` | 32位整数 |
+
+### 常用地址示例
+
+```csharp
+// 浮点数读取
+"VD100"   // V区第100字节开始的双字（4字节浮点数）
+"MD50"    // M区第50字节开始的双字
+
+// 整数读取
+"VW100"   // V区第100字节开始的字（2字节）
+"MW10"    // M区第10字节开始的字
+
+// 布尔值读取
+"M10.0"   // M区第10字节的第0位
+"Q0.5"    // Q区第0字节的第5位
+"V100.3"  // V区第100字节的第3位
+
+// 字节读取
+"VB100"   // V区第100字节
+"MB10"    // M区第10字节
+```

+
+## 配置文件结构
+
+项目使用 JSON 配置文件管理 PLC 连接参数，支持运行时修改。
+
+### 配置文件示例（yzwater-config.json）
+
+```json
+{
+    "PlcIp": "192.168.2.100",
+    "PlcPort": 102,
+    "AutoConnect": true,
+    "PlcProtocol": "SiemensS7",
+
+    "LevelHighAlarm": 80.0,
+    "LevelLowAlarm": 20.0,
+    "FlowHighAlarm": 100.0,
+    "FlowLowAlarm": 5.0,
+
+    "PlcAddresses": {
+        "Tank1Level": "VD100",
+        "Tank2Level": "VD104",
+        "InflowRate": "VD200",
+        "OutflowRate": "VD204",
+        "Pump1Freq": "VD300",
+        "Pump1Current": "VD320"
+    }
+}
+```
+
+### 配置模型类
+
+```csharp
+using System.Text.Json;
+using System.Text.Json.Serialization;
+
+public class SystemConfig
+{
+    // PLC 连接
+    public string PlcIp { get; set; } = "192.168.2.100";

+    public float FlowHighAlarm { get; set; } = 100f;
+    public float FlowLowAlarm { get; set; } = 5f;
+
+    // 地址覆盖
+    public Dictionary<string, string>? PlcAddresses { get; set; }
+}
+
+public static class ConfigService
+{
+    private static SystemConfig? _config;
+    private static readonly string ConfigPath = "yzwater-config.json";
+
+    public static SystemConfig GetConfig()

+        var json = JsonSerializer.Serialize(_config, options);
+        File.WriteAllText(ConfigPath, json);
+    }
+}
+```
+
+### 配置加载顺序
+
+```csharp
+// 在程序启动时按顺序加载：
+
+// 1. 加载主配置文件
+ConfigService.Load();
+
+// 2. 加载地址覆盖（覆盖默认硬编码地址）
+PlcConfig.LoadFromConfig();
+
+// 3. 初始化 PLC 服务
+PlcService.Initialize();
+```

+## 使用示例
+
+### 基础使用
+
+```csharp
+// 创建连接
+var plc = new SiemensPlcHelper();
+var connected = await plc.ConnectAsync("192.168.0.150", 102);
+
+if (connected)
+{
+    // 读取浮点数
+    var level = await plc.ReadFloatAsync("VD100");
+    Console.WriteLine($"液位: {level:F2}");
+
+    // 读取布尔值
+    var pumpRun = await plc.ReadBoolAsync("M10.0");
+    Console.WriteLine($"泵运行: {pumpRun}");
+
+    // 写入浮点数
+    await plc.WriteFloatAsync("VD200", 123.45f);
+
+    // 写入布尔值
+    await plc.WriteBoolAsync("M20.0", true);
+
+    // 批量读取
+    var bytes = await plc.ReadBytesAsync("V100", 20);
+    if (bytes != null)
+    {
+        for (int i = 0; i < 5; i++)
+        {
+            var value = ParseFloat(bytes, i * 4);
+            Console.WriteLine($"VD{100 + i * 4}: {value:F2}");
+        }
+    }
+}
+
+// 断开连接
+plc.Disconnect();
+```
+
+### 使用轮询服务
+
+```csharp
+// 创建轮询服务
+var polling = new PlcPollingService();
+
+// 订阅事件
+polling.DataUpdated += data => 
+{
+    Console.WriteLine($"液位: {data.GetValueOrDefault("TankLevel"):F2}");
+    Console.WriteLine($"流量: {data.GetValueOrDefault("FlowRate"):F2}");
+};
+
+polling.ConnectionStateChanged += connected =>
+{
+    Console.WriteLine(connected ? "PLC 已连接" : "PLC 已断开");
+};
+
+polling.ErrorOccurred += error =>
+{
+    Console.WriteLine($"错误: {error}");
+};
+
+// 启动（IP: 192.168.0.150, 端口: 102, S7-200Smart）
+polling.Start("192.168.0.150", 102, SiemensPLCS.S200Smart);
+
+// 程序退出时停止
+Console.WriteLine("按任意键停止...");
+Console.ReadKey();
+polling.Stop();
+```

+
+## 多协议驱动抽象（可选扩展）
+
+如果项目未来可能需要切换 PLC 品牌（三菱/欧姆龙/Modbus 等），可以使用统一的驱动接口抽象。
+
+### IPlcDriver 接口
+
+```csharp
+using HslCommunication;
+
+/// <summary>
+/// PLC 驱动接口 - 统一的 PLC 通信抽象
+/// </summary>
+public interface IPlcDriver : IDisposable
+{
+    string Name { get; }
+    bool IsConnected { get; }
+
+    Task<OperateResult> ConnectAsync();
+    void Disconnect();
+
+    Task<OperateResult<byte[]>> ReadBytesAsync(string address, ushort length);
+    Task<OperateResult<float>> ReadFloatAsync(string address);
+    Task<OperateResult<bool>> ReadBoolAsync(string address);
+
+    Task<OperateResult> WriteAsync(string address, byte[] value);
+    Task<OperateResult> WriteFloatAsync(string address, float value);
+    Task<OperateResult> WriteBoolAsync(string address, bool value);
+}
+
+/// <summary>
+/// PLC 协议类型
+/// </summary>
+public enum PlcProtocol
+{
+    SiemensS7,       // 西门子 S7
+    MitsubishiMC,    // 三菱 MC
+    OmronFins,       // 欧姆龙 Fins
+    ModbusTcp,       // Modbus TCP
+    AllenBradley     // AB EtherNet/IP
+}
+```
+
+### SiemensS7Driver 实现
+
+```csharp
+using HslCommunication;
+using HslCommunication.Profinet.Siemens;
+
+public class SiemensS7Driver : IPlcDriver
+{
+    private readonly SiemensS7Net _plc;
+    private bool _disposed;
+    private bool _isConnected;
+

+        _plc = new SiemensS7Net(plcSeries);
+    }
+
+    public void SetConnection(string ipAddress, int port = 102)

+
+    public async Task<OperateResult> ConnectAsync()

+        _isConnected = false;
+    }
+
+    public async Task<OperateResult<byte[]>> ReadBytesAsync(string address, ushort length)
+        => await _plc.ReadAsync(address, length);
+
+    public async Task<OperateResult<float>> ReadFloatAsync(string address)
+        => await _plc.ReadFloatAsync(address);
+
+    public async Task<OperateResult<bool>> ReadBoolAsync(string address)
+        => await _plc.ReadBoolAsync(address);
+
+    public async Task<OperateResult> WriteAsync(string address, byte[] value)
+        => await _plc.WriteAsync(address, value);
+
+    public async Task<OperateResult> WriteFloatAsync(string address, float value)
+        => await _plc.WriteAsync(address, value);
+
+    public async Task<OperateResult> WriteBoolAsync(string address, bool value)
+        => await _plc.WriteAsync(address, value);
+
+    public void Dispose()
+    {
+        if (_disposed) return;
+        _disposed = true;
+        Disconnect();
+        _plc.Dispose();
+    }
+}
+```
+
+### PlcDriverFactory 工厂
+
+```csharp
+public static class PlcDriverFactory
+{
+    public static IPlcDriver Create(PlcProtocol protocol, string ipAddress, int port)
+    {
+        IPlcDriver driver = protocol switch
+        {
+            PlcProtocol.SiemensS7 => CreateSiemensS7(ipAddress, port),
+            // 可扩展其他品牌...
+            _ => throw new NotSupportedException($"不支持的 PLC 协议: {protocol}")
+        };
+        return driver;
+    }
+
+    private static SiemensS7Driver CreateSiemensS7(string ipAddress, int port)
+    {
+        var driver = new SiemensS7Driver(SiemensPLCS.S200Smart);

+        PlcProtocol.ModbusTcp     => 502,
+        PlcProtocol.AllenBradley  => 44818,
+        _ => throw new NotSupportedException($"不支持的 PLC 协议: {protocol}")
+    };
+}
+```

+
+## 支持的 PLC 系列
+
+| 枚举值 | PLC 型号 | 说明 |
+|--------|----------|------|
+| `SiemensPLCS.S200` | S7-200 | 老型号 |
+| `SiemensPLCS.S200Smart` | S7-200 Smart | 默认，常用 |
+| `SiemensPLCS.S300` | S7-300 | 中大型 |
+| `SiemensPLCS.S400` | S7-400 | 大型 |
+| `SiemensPLCS.S1200` | S7-1200 | 新型紧凑型 |
+| `SiemensPLCS.S1500` | S7-1500 | 新型高性能 |
+
+### 指定 PLC 系列
+
+```csharp
+// S7-1200
+await plc.ConnectAsync("192.168.0.1", 102, SiemensPLCS.S1200);
+
+// S7-1500
+await plc.ConnectAsync("192.168.0.1", 102, SiemensPLCS.S1500);
+
+// S7-300
+await plc.ConnectAsync("192.168.0.1", 102, SiemensPLCS.S300);
+```
+
+---
+
+## 常见问题
+
+### 连接失败
+
+1. 检查 IP 地址和端口是否正确
+2. 确认 PLC 与 PC 网络连通（ping 测试）
+3. 检查 PLC 是否已启用 PUT/GET 通信
+4. 确认防火墙未阻止 102 端口
+
+### 读取数据为 0
+
+1. 确认地址格式正确（如 VD100 而非 V100）
+2. 检查数据类型是否匹配（浮点数用 VD，整数用 VW）
+3. 检查字节序是否正确（使用 ParseFloat 方法）
+
+### 读取数据异常
+
+1. 确认 PLC 系列选择正确
+2. 检查地址范围是否超出 PLC 实际配置
+3. 使用 Wireshark 抓包分析通信数据
+
+### 批量读取失败
+
+1. 确认地址在同一区域内连续（不能跨区）
+2. 读取长度不要超过 PLC 限制（S7-200 最大 240 字节）
+3. 使用 `S7AddressParser.GroupConsecutiveAddresses()` 自动分组
+
+### 轮询服务 CPU 占用高
+
+1. 适当增大 `PollingIntervalMs`（默认 1000ms）
+2. 增大 `DeadbandPercent` 减少 UI 刷新次数
+3. 使用批量读取替代多次单独读取
+
+---
+
+## 日志集成（Serilog）
+
+```csharp
+using Serilog;
+
+// 初始化日志（程序启动时调用一次）
+public static void InitializeLogging()
+{
+    Log.Logger = new LoggerConfiguration()
+        .MinimumLevel.Information()
+        .WriteTo.Console()
+        .WriteTo.File(
+            path: "Logs/log-.txt",
+            rollingInterval: RollingInterval.Day,
+            outputTemplate: "{Timestamp:yyyy-MM-dd HH:mm:ss.fff} [{Level:u3}] {Message:lj}{NewLine}{Exception}")
+        .CreateLogger();
+}
+
+// 在程序退出时关闭
+public static void CloseLogging()
+{
+    Log.CloseAndFlush();
+}
+```
+
+### 日志使用示例
+
+```csharp
+Log.Information("PLC 连接成功: {Ip}:{Port}", ip, port);
+Log.Warning("PLC 连接失败: {Message}", result.Message);
+Log.Error(ex, "读取 PLC 数据失败，地址: {Address}", address);
+Log.Debug("批量读取优化: {Count} 个地址合并为 {Groups} 次读取", count, groups);
+```

+# 发现与决策
+
+## 需求
+- 集成三个库：Stateless（状态机）、Elsa Workflows（工作流）、Quartz.NET（定时任务）
+- 目标：完善项目架构，提升设备状态管理、工艺流程编排、任务调度能力
+- 完成后编译提交，问题归档到 docs/
+
+## 研究发现
+
+### 项目现状
+- **框架**：.NET 8 + Avalonia UI 12 + CommunityToolkit.Mvvm
+- **状态机库**：❌ 未安装
+- **任务编排库**：❌ 未安装
+- **自定义状态机**：❌ 无（仅有枚举 + 三元表达式描述设备状态）
+- **任务调度方式**：手写 `while` + `Task.Delay` 轮询循环，`System.Timers.Timer` 做 UI 定时
+
+### 现有设备状态
+- `DeviceStatus` 枚举：`Stopped / Running / Fault / Maintenance`
+- `ValveStatus` 枚举：`Open / Closed / Middle`
+- `MainViewModel` 中用三元表达式映射状态到 UI 文本/颜色
+- 位置：`Models/EquipmentStatus.cs`
+
+### 现有任务调度
+| 组件 | 方式 | 文件位置 |
+|---|---|---|
+| `PlcPollingService` | `Task.Run` + `while(!ct)` + `Task.Delay(PollingIntervalMs)` | `Services/PlcPollingService.cs` |
+| `DataLoggingService` | `while(!ct)` + `Task.Delay(1000)` + 计数器 | `Services/DataLoggingService.cs` |
+| `MainViewModel` | `System.Timers.Timer(1000)` | `ViewModels/MainViewModel.cs` |
+
+### 启动流程（App.axaml.cs）
+```
+OnFrameworkInitializationCompleted() → DatabaseService.Initialize()
+  → ShowLoginWindow() → [登录成功] → StartServices() → ShowMainWindow()
+  
+StartServices() → 根据 RunMode 选择:
+  - Direct: StartPlcServices()
+  - Server: StartPlcServices() + HubServer
+  - Client: HubClient + DataLoggingService
+  
+StartPlcServices():
+  - Mock模式: MockPlcService.Enable()
+  - 真实模式: PlcService.Initialize()
+  - PlcPollingService.Instance.Start()
+  - AlarmService.Instance.Start()
+  - DataLoggingService.Start()
+```
+
+### 集成点分析
+
+#### 1. Stateless 状态机
+- **目标**：为泵、阀门、报警创建设备状态机
+- **替换**：`DeviceStatus` 枚举的三元表达式映射
+- **新增**：状态转换规则（如 Stopped → Running、Running → Fault）
+- **位置**：创建 `Services/DeviceStateMachine.cs`
+
+#### 2. Quartz.NET 定时任务
+- **目标**：替代手写的 `while+Task.Delay` 轮询
+- **替换**：
+  - `PlcPollingService.PollingLoopAsync()` → `PlcPollingJob`
+  - `DataLoggingService.LoggingLoopAsync()` → `DataLoggingJob`
+  - `MainViewModel._clockTimer` → 保持原样（UI 时钟不适合 Quartz）
+- **位置**：创建 `Services/QuartzSchedulerService.cs` 和 Jobs 目录
+
+#### 3. Elsa Workflows 工作流
+- **目标**：支持工艺流程编排（如污水处理流程）
+- **新增**：配置 Elsa 服务，创建示例工作流
+- **位置**：创建 `Services/WorkflowService.cs` 和 `Workflows/` 目录
+
+## 技术决策
+| 决策 | 理由 |
+|------|------|
+| Stateless 用于设备状态建模 | 轻量零依赖，Fluent API 适合工业设备 |
+| Quartz.NET 用于定时任务 | 成熟稳定，支持 cron 表达式，替代手写轮询 |
+| Elsa Workflows 用于流程编排 | .NET 生态最活跃的工作流引擎，支持可视化 |
+| MainViewModel 的 UI 时钟保留 System.Timers.Timer | UI 定时器不适合用 Quartz（需要与 UI 线程交互） |
