【摘要】 TRB模式(列车通信控制限制/备份模式)是地铁列车运行中通信系统发生故障时所采用的一种列车紧急控制模式。针对地铁列车运行初期列车控制单元经常发生的通讯故障,基于列车通信系统的结构和工作原理,阐述了列车正常控制模式和紧急控制模式下的实现原理,对列车通信系统出现故障下的TRB模式应用中两种通信故障进行了分析,提出了相应的故障处理及整改措施。经后续实际运行测试证明,在TRB模式下列车的各项功能均能够正常实施。更多还原

【Abstract】 The TRB(train communication control restriction/backup mode) model is a kind of emergency control mode for metro train operation.Communication failure of train control unit in the initial stage of metro train operation.According to the frequent communication failures in control units during the early operation,and based on the structure and working principle of the train communication system,the realization principle in normal control mode and emergency control mode of metro trains are expounded,two kinds of communication failure in train TRB mode application are analyzed,corresponding fault treatment and rectification measures are proposed.Practical operation test has certificated that various functions of the train TRB mode are able to perform normally.更多还原
