与dgiot技术群沟通，为设备设置定位，已知存储时为WGS-84坐标

如图所示，假设某点位WGS-84坐标为 120.151916,30.313093，那么转换成百度地图坐标bd09坐标系应该是120.156622,30.310774 (接近值)

通过iotapi接口查询设备发现，。百度地图点位有较大偏差（bd09坐标系，iotapi接口返回的数据，与标准的坐标转换过程（WGS-84->GCJ-02->Bd09）产生的结果有较大偏差，实际偏差距离上百米。

另外就是设备设置好的定位，与设备详情里显示的位置不一致，有较大偏差

麻烦修复下，设置的位置与显示的保持一致，最好接口中加两项，可以查询设备的WGS-84未偏移坐标，方便开发人员外换算其他非百度地图坐标。
