摘要
为实现对现代有轨电车车辆的位置及运行状态进行实时监控,设计了一个基于BDS/GPS和百度地图的现代有轨电车监控系统;定位终端以具有我国自主知识产权的BDS/GPS双模定位模块为主,RFID系统作为辅助定位手段;数据通过HTTP的GET方法提交至服务器,由服务器端的PHP页面自动处理后存储到MySQL数据库,中心管理平台显示页面调用百度地图API,将数据显示在百度地图上;最终该系统可以实时获取并存储列车的位置坐标、速度、时间等信息,并在百度地图上以点、线和图表的形式显示出车辆的坐标和运行轨迹等;测试结果表明,该系统运行稳定,定位精度高,获取数据准确、时延小,能够满足应用需求。
In order to realize real--time monitoring on the position and operating status of the modern streetcar vehicles, we have de signed a modern streetcar monitoring system based on BDS/GPS and Baidu Maps. Positioning terminal is mainly composed by BDS/GPS dual mode positioning module of which intellectual property is owned by our country, and RFID system is as a supplement. Here, data is sub- mitred to server via HTTP--Get, the PHP page at the server--side is automatically handled and then stored in the MySQL database. Baidu map API is called by center management platform and the data is displayed on Baidu map. Finally, the system can obtain and store real--time position coordinates, velocity and time information, then Baidu map shows the coordinates and the traiectory of the vehicle in the form of points, lines and charts, etc. The test results show that the system is stable, high precise, accurate, low delayed and meet the application requirements.
