+# PowerManager系统架构优化设计方案
+
+## 1. 总体架构
+```mermaid
+classDiagram
+    class PowerManagerCore {
+        +startup()
+        +shutdown()
+        +getSystemState()
+    }
+
+    class StateMachineService {
+        +triggerEvent()
+        +getCurrentState()
+        +addStateListener()
+    }
+
+    class CommunicationMediator {
+        +registerHandler()
+        +sendMessage()
+        +addMessageListener()
+    }
+
+    PowerManagerCore --> StateMachineService
+    PowerManagerCore --> CommunicationMediator
+```
+
+## 2. 状态机重构方案
+
+### 2.1 状态设计模式
+```cpp
+class IPowerState {
+public:
+    virtual void onEntry(PowerContext&) = 0;
+    virtual void handleEvent(PowerContext&, const Event&) = 0;
+    virtual void onExit(PowerContext&) = 0;
+};
+```
+
+### 2.2 状态转换规则
+```yaml
+# states_config.yaml
+transitions:
+  - from: STANDBY
+    event: START_CMD
+    to: OPERATING
+  - from: OPERATING
+    event: STOP_CMD
+    to: STANDBY
+```
+
+## 3. 通信中介者设计
+
+### 3.1 核心架构
+```mermaid
+sequenceDiagram
+    participant Upper as 上位机
+    participant Mediator as 通信中介者
+    participant Lower as 下位机
+    
+    Upper->>Mediator: 控制命令(JSON)
+    Mediator->>Lower: 设备指令(ProtocolBuffer)
+    Lower->>Mediator: 状态更新
+    Mediator->>Upper: 系统报告
+```
+
+### 3.2 关键实现
+```cpp
+class CommunicationMediator {
+    // 线程安全消息队列
+    moodycamel::ConcurrentQueue<Message> queue;
+    
+    // 消息处理线程
+    void processMessages() {
+        while (running) {
+            Message msg;
+            if (queue.try_dequeue(msg)) {
+                handlers[msg.type]->handle(msg);
+            }
+        }
+    }
+};
+```
+
+## 4. 数据库服务设计
+
+### 4.1 日志策略模式
+```cpp
+class ILogStrategy {
+public:
+    virtual bool log(const SystemLog& log) = 0;
+};
+
+class SQLiteLogStrategy : public ILogStrategy {
+    // SQLite实现...
+};
+
+class FileLogStrategy : public ILogStrategy {
+    // 文件系统实现...
+};
+```
+
+## 5. 实施计划
+
+### 5.1 阶段划分
+```mermaid
