【摘要】：随着物联网和移动实时地理信息系统的发展,基于地图的传感器实时监控系统将成为管理物联设备的新途径,而传感器数据的实时可视化是提高监管效率的主要方法。该文提出一种以开源OSMDroid(Open Street Map)为地图平台,基于自定义矢量地图符号实时展示传感器数据的方法,并在Android移动终端上实施验证。该方法利用可缩放矢量图形(Scalable Vector Graphic,SVG)将传感器设备抽象为自定义矢量地图符号,根据传感器数据类型设计地图符号图元与传感器数据的映射规则,据此在地图上实时刷新传感器设备地图符号。地图符号的视觉变量随传感器数据实时改变,从而实现传感器数据的实时可视化显示。实验结果表明,通过地图符号实时可视化传感器数据可有效提高传感器设备管理效率,及时获取设备数据,为传感器设备管理提供一种直接有效的途径。
[Abstract]:With the development of Internet of things and mobile real time geographic information system, the real time monitoring system based on map will become a new way to manage the device. The real-time visualization of sensor data is the main method to improve the efficiency of supervision. This paper presents a method of displaying sensor data in real time based on self-defined vector map symbols based on open source OSMDroid Open Street Map platform. The method is verified on Android mobile terminal. In this method, the sensor device is abstracted into a self-defined vector map symbol by Scalable Vector Graphics (SVG), and the mapping rules between the map symbol element and the sensor data are designed according to the sensor data type. Accordingly, the map symbol of sensor device is refreshed in real time on the map. The visual variables of map symbols change with the sensor data in real time, so that the real-time visualization of sensor data can be realized. The experimental results show that the real-time visualization of sensor data with map symbols can effectively improve the efficiency of sensor equipment management and obtain the device data in time, which provides a direct and effective way for sensor equipment management.
