摘要
无人自动折返是城市轨道交通广泛应用的一种列车折返方式,此方法有效的提高了折返效率,减少司机使用数量,降低人力成本,提高了列车自动化运行水平.针对西安地铁14号线城际列车频繁发生无人自动折返失败的故障,从车载信号控制系统与车辆牵引制动执行角度进行深入研究分析,提出三种解决方案,根据不同阶段的探索与测试,最终通过修改列车折返判定停稳条件及车辆提升列车冲击率的方式有效解决此类故障.
Abstract
Unmanned automatic turnback widely used in urban rail transit.This method effectively improves turnback efficiency,reduces the number of drivers used,reduces labor costs,and improves the level of train automa-tion operation.In response to the frequent failure of unmanned automatic turn back of intercity trains on Xi'an Metro Line 14,in-depth research and analysis were conducted from the perspectives of onboard sig-nal control system and vehicle traction and braking execution.Three solutions were proposed,and based on exploration and testing at different stages,effective solutions were finally proposed by modifying the stopping conditions for train turn back judgment and improving the train impact rate.
