PowerManager系统架构优化设计方案

1. 总体架构

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

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

# 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

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

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

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...
};
