TrainGuard MT系统雷达测速故障探讨及解决方案

Solution of Velocity Measurement Failure in TrainGuard MT Radar

针对广州地铁信号TrainGuard MT系统在雨天环境下频发的紧急制动故障,从列车定位原理、测速融合原则及ATP系统对于测速结果的处理等方面,对故障原因进行了深入的分析,并提出了有效的解决方案。

This paper deals with emergency brake failures frequently occurring in Guangzhou Metro Line 4. We analyze the reason of emergency brake failures through working principle of train positioning and fusion of velocity sensor and ways of ATP system~ velocity measurement results handling. At last, we put forward a feasible solution
