设备采用GPS定位时物模型-地理位置属性说明
设备端上报数据示例
Topic:
/sys/{productKey}/{deviceName}/thing/event/property/post
Payload:
{
"id":"123",
"version":"1.0",
"params":{
"GeoLocation":{
"value":{
"Longitude":115.2334,
"Latitude":39.4563,
"Altitude":235,
"CoordinateSystem":2
}
}
},
"method":"thing.event.property.post"
}
物模型-事件说明
设备通过WiFi定位通信示例:
Topic:
/sys/{productKey}/{deviceName}/thing/event/LocationInfo/post
Payload:
{
"id":"123",
"version":"1.0",
"params":{
"mmac":"4c:48:da:26:ea:d9,-56,iot",
"macs":"4c:48:da:26:ea:d8,-56,iot|e6:a4:71:6e:45:83,-58,iot-LV4mshO"
},
"method":"thing.event.LocationInfo.post"
}
物模型-事件说明
非CDMA基站,设备上报数据示例:
Topic:
/sys/{productKey}/{deviceName}/thing/event/LocationInfo/post
Payload:
{
"id":"123",
"version":"1.0",
"params":{
"imei":"352315052834187",
"smac":"E0:DB:55:E4:C7:49",
"cdma":"0",
"bts":"460,01,40977,2205409,-65",
"nearbts":"460,01,40977,2205409,-65|460,01,40 977,2205409,-65|460,01,40977,2205409,-65"
},
"method":"thing.event.LocationInfo.post"
}
CDMA基站,设备上报数据示例:
Topic:
/sys/{productKey}/{deviceName}/thing/event/LocationInfo/post
Payload:
{
"id":"123",
"version":"1.0",
"params":{
"imei":"0000",
"smac":"E0:DB:55:E4:C7:49",
"cdma":"1",
"bts":"13824,1,1838,1674723,575739,-52"
},
"method":"thing.event.LocationInfo.post"
}
云端业务系统获取设备位置API业务系统调用QueryDevicePropertyData 查询IoT设备的位置
业务系统通过QueryDevicePropertyData API 查询具体设备的位置信息
CommonRequest request = new CommonRequest();
request.setSysMethod(MethodType.POST);
request.setSysDomain("iot.cn-shanghai.aliyuncs.com");
request.setSysVersion("2018-01-20");
request.setSysAction("QueryDevicePropertyData");
request.putQueryParameter("RegionId", "cn-shanghai");
request.putQueryParameter("StartTime", "1618330349204");
request.putQueryParameter("Identifier", "GeoLocation");
request.putQueryParameter("Asc", "0");
request.putQueryParameter("EndTime", "1629330349204");
request.putQueryParameter("PageSize", "10");
request.putQueryParameter("IotInstanceId", "iot-068a03kg");
request.putQueryParameter("ProductKey", "g7palBDnzmT");
request.putQueryParameter("DeviceName", "dk003");
CommonResponse response = client.getCommonResponse(request);
返回值:
{
"RequestId": "C56790F8-AC96-492C-BA86-D7F57F090795",
"Data": {
"NextValid": false,
"NextTime": 1619330564810,
"List": {
"PropertyInfo": [
{
"Value": "{\"altitude\":0,\"CoordinateSystem\":2,\"latitude\":39.9932251,\"longitude\":116.4727718}",
"Time": 1619330564811
}
]
}
},
"Code": "",
"Success": true
}
