""" AI Box Sophon Adapter 插件 基于 MQTT 的 AI Box 设备心跳适配器，实现： 1. 通过 MQTT 主题接收设备心跳上报 2. 解析设备系统参数（温度、硬盘、内存、通道、任务、TPU 等） 3. 持久化心跳数据到 SQLite 数据库 4. 提供 HTTP API 查询设备在线状态和详情 5. 后台定时检查离线设备，触发异常告警 6. 视频上传接口 — 盒子告警时录制视频上传（FORM-DATA） 7. 告警上报接口 — 违规事件 JSON 报文字动解析入库 8. 告警查询接口 — 告警列表/详情查询 9. IN2 任务启停开关 — DI 输入有电启动全部任务，断电停止全部任务 心跳超时机制: - 设备按配置间隔（默认 5 秒）上报心跳 - 服务端每 check_interval 秒检查一次 - 超过 heartbeat_timeout 秒未收到心跳的设备标记为离线 生命周期: 基于 Plugin 基类统一管理（数据库/后台任务/清理钩子由基类处理）， MQTT 客户端启动块已抽取到 mqtt_clients 能力组件。 """ import asyncio import logging import shutil from datetime import datetime from pathlib import Path from chongming_worker.plugin import Plugin from .router import * #
