电子标签辅助GPS实现列车监控的原型系统设计与实现

DESIGN AND IMPLEMENTATION OF A PROTOTYPE SYSTEM FOR TRAINS MONITORING WITH ELECTRON-TAG AIDED GPS

针对GPS盲区无法定位的问题,设计了将无线射频标签技术(RFID)用于辅助GPS实现列车监控的解决方案,并进行模拟验证。采用RFID辅助监控,通过将RFID数据转换、与GPS数据融合等处理,实现线路全程的列车监控,了解列车在沿线的运行情况。如果有突发事件发生,车辆监控中心能够采取有效方式进行及时解决,保障行车安全。

In order to cover the problem that location can not work in GPS blind area, RFID tag is introduced into trains monitoring system as a solution designed to assist GPS to realize the trains monitoring, and the solution is evaluated by simulation. Using RFID aided monitoring, processing the data transferred by RFID and integrating it with geographic data of GPS,the overall monitoring on trains travelling route is realized by mastering the running status of the trains along the way. For any accident occurred, the trains monitoring centre is able to deal with in time with effective measures, this guarantees the train operation safety.
