摘要
基于通信的列车控制(CBTC)系统通过数据通信子系统(DCS)构建了可靠的车地无线通信传输方式。介绍了上海轨道交通11号线CBTC系统车地通信的构成及其工作原理,分析了列车模式丢失故障的原因主要为无线接入点受潮、设备性能下降、外部信号干扰等,并提出了有效的解决方案。
A reliable wireless train to wayside communication(TWC)mode is established based on CBTC(communication based train control)system and through the data communication subsystem(DCS).In this paper,the structure and working principle of TWC mode in Shanghai metro Line 11 CBTC system are introduced,the causes for train mode loss failure like wireless access point damp,equipment performance degradation and external signal interference are analyzed,effective solutions are proposed.
