摘要:
正常情况下,计轴设备故障不会对CBTC模式下的列车运行产生影响,但当计轴设备故障发生在特定情境下时,会造成故障区域道岔无法转换,列车进路无法排列,列车无法以CBTC模式或点式ATP模式运行,对运营服务造成严重影响。通过深入研究、分析该特定情境与计轴宕机的关系,并结合现有系统的实际情况,提出一种可有效减小计轴CPU板宕机故障影响的优化方案。
Abstracts:
Normally, the axle counter failure will not affect the train operation in CBTC mode. But in specific conditions, it will lead to turnout switch failures in the fault area, train route arrangement failures, train operation failures in CBTC mode or Intermittent ATP mode, and cause serious impact on operational service. Through in-depth study and analysis of the relationship between specific conditions and axle counter failures, and referring to the real situation of the existing system, an optimization scheme is put forward for minimizing the impact of axle counter system downtime failure.
