摘　　要：列控车载设备驾驶室激活信号故障会导致动车组制动停车,影响运输效率。通过对CTCS3-300T型列控车载设备驾驶室激活信号典型故障案例分析,总结故障发生的规律,提出优化软件处理逻辑,增加故障定位分析手段,以提高预防故障的有效性和定位故障的准确性。When the cab activation signal fault occurs to the on-board equipment of CTCS3-300 T train control system,it will cause the EMU to stop and affect the efficiency of transportation.Based on case study of typical cab activation signal fault occurring to the onboard equipment of CTCS3-300 T train control system,the fault rule is summed up.Furthermore,it is proposed that the processing logic of its software be optimized by adding fault pinpointing and analysis functions in order to improve the effectiveness of fault prevention and the accuracy of fault pinpointing.
