Tortoise.subscribe(client, topic, qos: config.qos) end) state %{ client: client, topics: config.topics, qos: config.qos, last_messages: %{} } {:ok, state} end impl Jido.Sensor def handle_event({:mqtt_message, topic, payload}, state) do # 解析设备数据 data Jason.decode!(payload) # 创建信号发送给代理 signal Jido.Signal.new!(%{ source: /sensor/mqtt/#{topic}, type: device.data_received, data: %{ topic: topic, payload: data, timestamp: DateTime.utc_now() } }) {:ok, %{state | last_messages: Map.put(state.last_messages, topic, data)}, [{:emit, signal}]} end end2. 设备状态管理代理每个物联网设备都可以被建模为一个独立的Jido代理负责管理设备状态和执行控制命令defmodule IoTDeviceAgent do use Jido.Agent, name: iot_device_agent, description: 物联网设备状态管理代理, schema: [ device_id: [type: :string, required: true], status: [type: :string, default: offline], last_seen: [type: :utc_datetime], telemetry: [type: :map, default: %{}], config: [type: :map, default: %{}] ], signal_routes: [ {device.data_received, HandleDeviceDataAction}, {device.command, ExecuteDeviceCommandAction}, {device.config_update, UpdateDeviceConfigAction} ] end物联网应用架构设计3. 分层代理架构在复杂的物联网系统中我们可以构建分层的代理架构物联网设备层 → 设备代理层 → 区域管理代理 → 中央控制代理每个层级都有特定的职责设备代理直接管理单个设备处理原始数据区域管理代理管理同一区域的多个设备进行数据聚合中央控制代理全局决策和策略执行4. 数据流处理管道Jido的信号机制为物联网数据流处理提供了优雅的解决方案defmodule DataPipelineAgent do use Jido.Agent, name: data_pipeline, description: 物联网数据处理管道, plugins: [ DataValidationPlugin, DataTransformationPlugin, DataAggregationPlugin, AlertGenerationPlugin ] end每个插件负责特定的数据处理阶段形成完整的数据处理管道。设备生命周期管理5. 设备注册与发现利用Jido的发现机制实现设备的自动注册defmodule DeviceDiscoverySensor do use Jido.Sensor, name: device_discovery, description: 设备发现传感器, schema: Zoi.object(%{ scan_interval: Zoi.integer() | Zoi.default(30000) }, coerce: true) impl Jido.Sensor def init(config, context) do state %{scan_interval: config.scan_interval} {:ok, state, [{:schedule, 0}]} # 立即开始扫描 end impl Jido.Sensor def handle_event(:scan, state) do # 扫描网络中的设备 devices scan_network_devices() Enum.each(devices, fn device -
