BatchPutMessage 暖通空调系统的示例 Amazon IoT Events

在本示例中，BatchPutMessage 用于为某个区域创建探测器实例并定义初始操作参数。

使用的 CLI 命令：

aws iotevents-data batch-put-message --cli-input-json file://seedExample.json --cli-binary-format raw-in-base64-out

文件：seedExample.json

{
  "messages": [
    {
      "messageId": "00001",
      "inputName": "seedTemperatureInput",
      "payload": "{\"areaId\": \"Area51\", \"desiredTemperature\": 20.0, \"allowedError\": 0.7, \"rangeHigh\": 30.0, \"rangeLow\": 15.0, \"anomalousHigh\": 60.0, \"anomalousLow\": 0.0, \"sensorCount\": 10, \"noDelay\": false}"
    }
  ]
}

响应：

{
    "BatchPutMessageErrorEntries": []
}

在本示例中，BatchPutMessage 用于报告某个区域中单个传感器的温度传感器读数。

使用的 CLI 命令：

aws iotevents-data batch-put-message --cli-input-json file://temperatureExample.json --cli-binary-format raw-in-base64-out

文件：temperatureExample.json

{
  "messages": [
    {
      "messageId": "00005",
      "inputName": "temperatureInput",
      "payload": "{\"sensorId\": \"05\", \"areaId\": \"Area51\", \"sensorData\": {\"temperature\": 23.12} }"
    }
  ]
}

响应：

{
    "BatchPutMessageErrorEntries": []
}

在本例中，BatchPutMessage 用于更改某个区域的所需温度。

使用的 CLI 命令：

aws iotevents-data batch-put-message --cli-input-json file://seedSetDesiredTemp.json --cli-binary-format raw-in-base64-out

文件：seedSetDesiredTemp.json

{
  "messages": [
    {
      "messageId": "00001",
      "inputName": "seedTemperatureInput",
      "payload": "{\"areaId\": \"Area51\", \"desiredTemperature\": 23.0}"
    }
  ]
}

响应：

{
    "BatchPutMessageErrorEntries": []
}
