天津地铁2、3号线计轴故障处理及实例分析

Procedure with Axle Counter Failure and A Case Study of Tianjin Metro Line 2 and Line 3

天津地铁2、3号线采用基于无线通信的列车控制系统,并利用计轴设备作为冗余支持。试运营以来,列控系统运行总体稳定,但计轴设备故障较为常见,对正常运营秩序有一定影响。根据计轴设备构成和工作原理,分析计轴故障对行车工作造成的影响。从行车人员的角度,阐述了计轴故障的基本处置方式。并以空港站为例,具体分析了计轴故障处置过程中的关键环节和注意事项。

Tianjin metro Line 2 and Line 3 have adopted radio communication based train control （CBTC） system which uses the axle counter equipment as redundancy support. Since the trial operation, the whole CBTC system has been very stable, but the failures occurred in axle counter system are quite often and directly influence the normal metro operation. According to the structure of axle counter system and its operating principle, the influences on train running are analyzed. From the angle of train operators, the procedure with axle counter failures is stated, according to a case study of Tianjin Airport Economic Area Station, the key points and links in failure procedure are analyzed in detail.
