摘　　要：联锁失效故障是地铁运营工作中处理难度最大的一类故障,行车调度员需要在完成故障区列车定位后方可下达故障区列车按电话闭塞法组织行车的命令,而列车定位的过程耗时较长,且易产生失误,后备定位系统则采用基站定位方法,在联锁失效时通过独立运行的终端显示故障区列车的位置,可大量节省列车定位的时间。文章通过介绍后备定位系统的原理、结构,以及在运营实践中的使用情况,得出后备定位系统在地铁联锁失效故障处置中所发挥的积极作用。Interlocking failure is the most difficult to be dealt with among all the faults in metro operations.After completing the train location in the fault section,the traffic dispatcher needs to command to organize the train operation in the fault sections according to the telephone blocking.The process of train location takes a long time and is prone to mistakes.The backup location system adopts the base station location method to display the position of the train in the fault section through independent display terminals in case of interlocking failure,which saves a lot of time for locating a train.This paper introduces the principles,structure,and applications of backup location system in operation practice,and concludes that the backup location system plays a positive role in the treatment of metro interlocking failure.
