传送门：5个视频解说，30个场景案例汇总

阿里云IoT企业物联网平台提供基于GPS，挪动基站、WiFi热点等信息来进行设施定位的辅助服务，厂商能够依据设施理论状况抉择不同定位计划。

GPS定位计划

参考文档  https://help.aliyun.com/docum...
设施采纳GPS定位时物模型-地理位置属性阐明

设施端上报数据示例

Topic：/sys/{productKey}/{deviceName}/thing/event/property/postPayload：{    "id":"123",    "version":"1.0",    "params":{        "GeoLocation":{            "value":{                "Longitude":115.2334,                "Latitude":39.4563,                "Altitude":235,                "CoordinateSystem":2            }        }    },    "method":"thing.event.property.post"}

WiFi热点定位计划

物模型-事件阐明

设施通过WiFi定位通信示例：

Topic：/sys/{productKey}/{deviceName}/thing/event/LocationInfo/postPayload：{    "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"}

蜂窝基站定位计划

物模型-事件阐明

非CDMA基站，设施上报数据示例：

Topic：/sys/{productKey}/{deviceName}/thing/event/LocationInfo/postPayload：{    "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，设施上报数据示例：

Topic：/sys/{productKey}/{deviceName}/thing/event/LocationInfo/postPayload：{    "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"}

云端业务零碎获取设施地位API
业务零碎调用QueryDevicePropertyData 查问IoT设施的地位

业务零碎通过QueryDevicePropertyData API 查问具体设施的地位信息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}
