为提高传统CBTC系统降级运行的效率,采用基于感知的车车通信列车运行控制系统(perception based train autonomous control system,PB-TACS)结合SIL4级感知"自主感知运行"的降级运行方案有着重要意义.通过研究增加备用通信WLAN设备,优化轨旁信号设备配置,采用自主感知后备运行级别(autonomous backup level,ABL)移动闭塞运行方案作为车车通信列车控制系统的降级系统,可减少列车区间停车等待时间、提升降级列车恢复效率、减少列车掉线问题.通过对基于感知的车车通信列车运行控制系统降级运行方案进行研究和探讨,为后续全面提升CBTC级别的后备运行方案的完整性和可用性提供有力保障.
Research and Analysis on the Perception Based Train Autonomous Control Sys-tem's Backup System
In order to improve the efficiency of traditional CBTC system's degraded mode,it is of great significance to adopt the perception based train autonomous control system(PB-TACS)combined with the SIL4 level perception"autonomous perception operation"degraded operation scheme.This article studies the addition of backup communi-cation WLAN devices,optimizes the wayside signal equipment configuration,and uses the autonomous backup level(ABL)moving block operation as the degraded system of the train-to-train communication train control system,which can reduce the interval stopping time of the train,improve the recovery efficiency of the degraded train,and reduce train disconnection problems.By studying and discussing the degraded operation scheme of the perception-based train-to-train communication train control system,it provides strong guarantee for the subsequent comprehensive im-provement of the CBTC level backup operation scheme's integrity and availability.
