【HarmonyOS】实战项目+智慧家居控制面板全解

欢迎加入开源鸿蒙跨平台社区:https://openharmonycrossplatform.csdn.net

摘要

本文详细介绍如何使用ArkTS在DevEco Studio中构建完整的智慧家居控制面板应用。通过华为IoT Kit或自定义网络请求连接智能设备,利用ArkUI的Grid、Swiper和状态管理实现动态设备卡片,支持点击开关灯、调节空调温度。借助鸿蒙分布式软总线,实现在手机控制、智慧屏同步显示,并将常用设备快捷操作封装为原子化服务卡片,一键添加到桌面。

技术栈:ArkTS 4.0.0 | DevEco Studio 6.0.0 | HarmonyOS API 12 | Huawei IoT Kit 1.0.0

八、最佳实践与性能优化

8.1 设备连接优化

typescript 复制代码
// 连接池管理
class DeviceConnectionPool {
  private maxConnections: number = 5;
  private connections: Map<string, DeviceConnection> = new Map();

  async getConnection(device: DeviceInfo): Promise<DeviceConnection> {
    // 检查是否有可用连接
    const existingConnection = this.connections.get(device.ipAddress);
    if (existingConnection && existingConnection.isAlive()) {
      return existingConnection;
    }

    // 如果连接池已满,移除最旧的连接
    if (this.connections.size >= this.maxConnections) {
      const oldest = this._findOldestConnection();
      await oldest.disconnect();
      this.connections.delete(oldest.id);
    }

    // 创建新连接
    const connection = await DeviceConnection.create(device);
    this.connections.set(device.ipAddress, connection);

    return connection;
  }

  /**
   * 查找最旧的连接
   */
  private _findOldestConnection(): DeviceConnection {
    let oldest: DeviceConnection | null = null;
    let oldestTime = Date.now();

    this.connections.forEach((connection, id) => {
      if (connection.createdTime < oldestTime) {
        oldest = connection;
        oldestTime = connection.createdTime;
      }
    });

    return oldest!;
  }
}

8.2 分布式同步优化

typescript 复制代码
// 优化的分布式同步策略
class OptimizedDistributedSync {
  // 批量同步间隔(毫秒)
  private static readonly SYNC_INTERVAL = 5000;

  // 优先级队列
  private highPriorityQueue: DistributedDeviceState[] = [];
  private lowPriorityQueue: DistributedDeviceState[] = [];

  /**
   * 添加同步任务
   */
  addSyncTask(state: DistributedDeviceState, priority: 'high' | 'low' = 'low'): void {
    if (priority === 'high') {
      this.highPriorityQueue.push(state);
      this.highPriorityQueue.sort((a, b) => b.priority - a.priority);
    } else {
      this.lowPriorityQueue.push(state);
    }
  }

  /**
   * 执行批量同步
   */
  async executeSync(): Promise<void> {
    const tasks = [
      ...this.highPriorityQueue,
      ...this.lowPriorityQueue.slice(0, 3)  // 每次最多同步3个低优先级任务
    ];

    if (tasks.length === 0) return;

    // 批量保存到分布式存储
    const success = await this._batchSaveDevices(tasks);

    // 清空已执行的任务
    this.highPriorityQueue = [];
    this.lowPriorityQueue.splice(0, 3);

    Logger.info('OptimizedDistributedSync',
      `批量同步 ${success.length}/${tasks.length} 个设备状态`);
  }

  /**
   * 批量保存设备
   */
  private async _batchSaveDevices(
    states: DistributedDeviceState[]
  ): Promise<number> {
    const savePromises = states.map(state => {
      return this.dataStore.kvStore!.put(
        `device_${state.deviceId}`,
        JSON.stringify(state)
      );
    });

    const results = await Promise.all(savePromises);
    return results.filter(r => r === true).length;
  }
}
