摘要
在当前的城市轨道交通全自动运行(FAO)系统中,不配备司机的列车其运行控制高度依赖列车自动运行(ATO)子系统。若控制端ATO设备发生故障,列车将无法维持自动运行,只能等待控制中心救援,救援难度将增大,运营效率大大降低。针对这种情况,文章提出了一种在信号系统中增加受限的自动驾驶模式(RAM),即当控制端ATO设备发生故障时,经控制中心授权后,列车可进入RAM模式,由车载列车自动防护(ATP)系统通过车辆网络系统(TCMS)控制列车,使其自动运行到下一站外停车。案例分析结果表明,该方案可大大减少救援时间,提高运营效率。
At present,in a fully automatic operation(FAO) system of urban rail transit,train operation is highly dependent on the automatic train operation(ATO) system as there is no driver in the train.If the ATO device at control end fails,the train will not be able to maintain automatic operation and can only wait for rescue from the operation control center.Especially,when a fault occurs in a long interval,the rescue difficulty will increase,and the operation efficiency will be greatly reduced.In view of this situation,this paper proposes a new solution that a restricted autopilot mode(RAM) is added to the signal system.When the ATO device at the control end fails,the train can enter into RAM after getting authorization from the operation control center.The onboard automatic train protection(ATP) system controls the train to stop outside the next station through train control and management system(TCMS),which greatly reduces the rescue time and improves the operation efficiency.
