摘要
在CBTC(基于通信的列车控制)系统中常会出现CBTC列车和非CBTC列车(非装备列车或通信故障列车)混合运营。为保证此时的运营安全,需要设置基于次级检测设备(计轴)和信号机的后备系统。这些信号机对于CBTC列车的正常运营是不需要的,因而这些信号机在CBTC下如何点灯就成为各CBTC系统中需要考虑的问题。通过分析CBTC系统中轨旁信号的各种显示方案的优缺点,并对国内各项目的轨旁信号显示方案进行统计,经参考国内、国际的相关标准后,建议对CBTC系统中的轨旁信号机显示应采用灭灯方案。
The CBTC train and non-CBTC train（not CBTC equipped train or radio failure train）is often put in the mixed traffic in CBTC system. To ensure the safety for this mixed traffic, it is necessary to set Block Mode with secondary detection device （axle counter） and wayside signal, but these signals are not useful for the CBTC train revenue service, so the signal aspect solution in CBTC shall be taken into account. Based on the analysis of different wayside signal aspect solutions in CBTC system, and compared with various wayside signal aspect solutions applied in the current projects, this paper refers to the relevant domestic and international standards, discusses what kind of waysides signal aspect solution could be better for CBTC system.
