摘要
后备模式是城市轨道交通信号系统在设备故障时降级运行、保证故障列车安全退出运营、保持运营效率的一种手段。介绍基于通信的列车控制(CBTC)信号系统的3种常用后备模式。计轴作为列车占用检测设备,是后备模式下的关键设备,重点介绍应用于上海地铁线路的2种计轴产品。
When signal equipment faults in urban rail transit, the fallback mode of CBTC system will be used in degraded operation to ensure the failed train to exit safely and keep certain operation ability. The paper presents three kinds of common fallback modes of the CBTC system. The axle counter, as train detection equipment, is key equipment in fallback mode. The paper mainly introduces two kinds of axle counter products used in Shanghai metro lines.
