The invention provides a method for remotely isolating air braking of a metro vehicle, which comprises the following steps: when emergency braking of the vehicle is unavailable or the braking is not relieved or the emergency braking is abnormally applied, a braking system outputs a hard wire braking fault signal to a TCMS, and the TCMS feeds back a single vehicle braking fault signal and a fault quantity to a signal system; when the signal system acquires that a hard wire braking fault signal is effective, the signal system applies emergency braking; if the number of the faults is 1, the signal system forwards an OCC remote isolation instruction after parking, a remote isolation valve in the BCU is directly driven, and air braking of the vehicle with the braking faults is isolated; and if the number of the faults is greater than or equal to 2, the signal system judges that a braking heavy fault occurs, applies emergency braking and applies to a control center for entering a creeping mode or rescue. According to the invention, remote isolation air braking can be realized, faults of the vehicle are quickly solved, the availability of the vehicle is improved, and normal operation of the vehicle is ensured.

    本发明提供一种远程隔离地铁车辆空气制动的方法,当车辆发生紧急制动不可用或制动不缓解或紧急制动异常施加时,制动系统输出硬线制动故障信号给TCMS,TCMS反馈单车制动故障信号和故障数量给信号系统;当信号系统采集到硬线制动故障信号有效,信号系统施加紧急制动;如果故障数量为1,停车后信号系统转发OCC远程隔离指令,直接驱动BCU内部的远程隔离阀,隔离发生制动故障车辆的空气制动;如果故障数量大于等于2时,信号系统判定为制动重故障,信号系统施加紧急制动,向控制中心申请进入蠕动模式或者救援。本发明可以实现远程隔离空气制动,快速解决车辆不缓解故障,提高车辆的可用性,保证车辆的正常运营。
