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/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"
}

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/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"
}

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/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，设施上报数据示例：

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：
