CBTC信号系统计轴子系统信息及故障的处理方式

Fault Treatment of Axle Counter Subsystem in CBTC Signal System

地铁CBTC信号系统的控制通常分为CBTC控制级、点式控制级以及联锁控制级,计轴子系统在CBTC控制级下作为辅助检测设备使用,在点式及联锁控制级下是必不可少的轨旁基础检测设备,为地铁日常运营的安全及效率提供了保障。本文介绍了计轴子系统的作用及CBTC信号系统对计轴相关信息的处理方式,并对计轴故障后的处置方法进行了探讨。

The control of the CBTC signal system is usually divided into three categories of CBTC control level,spot transmission control level and interlock control level.The axle counter subsystem is used as auxiliary detection equipment under the CBTC control level while as trackside basic detection equipment under spot transmission level and interlock control level.The axle counter subsystem is essential for the safety and efficiency of smooth operation of the metro.The role of the axle counter subsystem and the processing of relevant axle counter data by the CBTC signal system are introduced.Finally,the disposal method after the axle counter fails is explored.
