地铁全自动运行系统故障软化技术

Fault Softening Technology for Metro Fully Automatic Operation System

采用GoA4级的地铁全自动运行系统取消了列车司机的设置,造成在异常或降级情况下列车迫停区间时救援人员上车救援困难且耗时较多,因而会严重影响地铁运营。根据具体的故障情况,提出了相应的故障软化技术,在列车全自动运行系统发生故障时,会保留部分自动运行功能,尽可能避免列车迫停于区间,以实现异常和降级情况下服务乘客、降低救援难度、对运营影响最小的目标。

Since the metro FAO system that adopted GoA4 cancelled the setting of train driver,in some abnormal scenarios or degrade cases,the train is forced to stop in a certain section,that makes it difficult for the rescue members to work,resulting in time wasting and even serious impact on train operation safety.In this paper,according to the specific fault,a corresponding fault softening technology is proposed.In case of the AFO system failure,part of the system functions will be retained and the train stopping between stations will be avoided,and the goals of minimum impact on the operation by reducing the rescue difficulties and serving the passengers in abnormal scenarios or degrade cases will be achieved.
