摘要:
［目的］上海轨道交通3、4号线信号系统升级改造后，其功能高度集中于车载列车控制器。一旦车载列车控制器发生故障导致列车降级,会使线路运营能力大幅下降，需要控制降级列车安全、高效地退出运营。对此，有必要研究降级列车的运行控制方法。［方法］介绍了上海轨道交通3、4号线TACS（列车自主运行系统）的设备结构特点，分析了列车降级运行场景，结合设备作用，详细阐述了列车降级后的运行控制方法。［结果及结论］列车降级运行后，轨旁列车控制器从轨旁资源控制器接管降级列车的资源，根据行车调度安排的行车任务，采用后备定位系统定位，代替车载列车管理器同轨旁资源管理器及其他列车进行资源交互，并通过信号机点灯来指挥行车。该方法维持了车-车通信的追踪逻辑，避免了在轨旁增加设备，降低了建设维护成本，适用于改造线路。
Abstracts:
［Objective］ After the upgrade of Shanghai Rail Transit Lines 3 and 4 signaling systems, their functions are highly concentrated in the on-board train controller. In the event of on-board train controller failure leading to train degraded status, the operational capacity of the line will decrease significantly, requiring a safe and efficient withdrawal of degraded trains from service. ［Method］ The structural characteristics of TACS （train autonomous circumambulate system） equipment for Shanghai Rail Transit Lines 3 and 4 are presented, the operational scenarios for train degradation are analyzed, and the operation control methods applicable after train degradation based on equipment role are elaborated. ［Result & Conclusion］ After a train enters the degraded state, the wayside train controller will take over the resource management from trackside resource controller. Based on the operational tasks assigned by train scheduling, a back-up localization system is utilized to replace the on-board train manager for resource interaction with the trackside resource managers and other trains，with signal lights serving to direct train operation. This method maintains the tracking logic for train-to-train communication, and is suitable for line upgrades by avoiding to add equipment on trackside and reducing construction and maintenance costs.
