HVAC 温度控制

背景故事

本示例实现了具有以下功能的温度控制模型(恒温器):

  • 您定义的一个检测器模型,可以监控和控制多个区域。(将为每个区域创建一个检测器实例。)

  • 每个检测器实例都会从放置在每个控制区域的多个传感器接收温度数据。

  • 您可以随时更改每个区域的所需温度(设定点)。

  • 您可以为每个区域定义操作参数,并随时更改这些参数。

  • 您可以随时向某个区域添加传感器或从中删除传感器。

  • 您可以启用时间加热和冷却装置的最小运行,以保护它们免受损坏。

  • 探测器将拒绝并报告异常传感器读数。

  • 您可以定义紧急温度设置点。如果任何一个传感器报告温度高于或低于您定义的设定点,则加热或冷却装置将立即启动,并且检测器将报告温度峰值。

此示例演示了以下功能功能:

  • 创建事件检测器模型。

  • 创建输入。

  • 将输入传输到检测器模型。

  • 评估触发条件。

  • 参考条件中的状态变量,并根据条件设置变量值。

  • 参考条件下的计时器并根据条件设置定时器。

  • 采取措施发送 Amazon SNS 和 MQTT 消息。

输入定义

A"seedTemperatureInput"用于为某个区域创建检测器实例并定义其运行参数。

CLI 命令:

aws iotevents create-input --cli-input-json file://seedInput.json

file:seedInput.json

{ "inputName": "seedTemperatureInput", "inputDescription": "Temperature seed values.", "inputDefinition": { "attributes": [ { "jsonPath": "areaId" }, { "jsonPath": "desiredTemperature" }, { "jsonPath": "allowedError" }, { "jsonPath": "rangeHigh" }, { "jsonPath": "rangeLow" }, { "jsonPath": "anomalousHigh" }, { "jsonPath": "anomalousLow" }, { "jsonPath": "sensorCount" }, { "jsonPath": "noDelay" } ] } }

响应:

{ "inputConfiguration": { "status": "ACTIVE", "inputArn": "arn:aws:iotevents:us-west-2:123456789012:input/seedTemperatureInput", "lastUpdateTime": 1557519620.736, "creationTime": 1557519620.736, "inputName": "seedTemperatureInput", "inputDescription": "Temperature seed values." } }

A"temperatureInput"应根据需要由每个区域的每个传感器发送。

CLI 命令:

aws iotevents create-input --cli-input-json file://temperatureInput.json

file:temperatureInput.json

{ "inputName": "temperatureInput", "inputDescription": "Temperature sensor unit data.", "inputDefinition": { "attributes": [ { "jsonPath": "sensorId" }, { "jsonPath": "areaId" }, { "jsonPath": "sensorData.temperature" } ] } }

响应:

{ "inputConfiguration": { "status": "ACTIVE", "inputArn": "arn:aws:iotevents:us-west-2:123456789012:input/temperatureInput", "lastUpdateTime": 1557519707.399, "creationTime": 1557519707.399, "inputName": "temperatureInput", "inputDescription": "Temperature sensor unit data." } }

探测器模型定义

这些区域有:"areaDetectorModel"定义了每个检测器实例的工作原理。EACH"state machine"实例将接收温度传感器读数,然后根据这些读数更改状态并发送控制消息。

CLI 命令:

aws iotevents create-detector-model --cli-input-json file://areaDetectorModel.json

file:areaDetectorModel.json
