Design of Modern Trams Monitoring System Based on BDS/GPS and Baidu Map

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。

Abstract:

To achieve the scientific management of modern trams, modern trams monitoring system based BDS / GPS and Baidu Map is designed. BDS / GPS dual-mode positioning module with intellectual property rights is adopted for positioning terminal to locate trams. GET method of HTTP sends data to a server, Baidu Map API is used by the monitoring center to display information including the coordinate of a tram, velocity, current time, conductors, train ID. A large amount of test results demonstrate the system, with the characteristics of running stably, high positioning accuracy, acquire data accurately and small delay, can meet the application requirements.
