摘要
以天津地铁5号线一次信号系统测试为背景,分析了信号车载系统软件升级后,出现列车在折返轨因碎石砟道床线路坡度与软件数据库中坡度参数存在较大偏差,从而导致列车触发紧急制动影响运营秩序的问题,并提出了如何避免该类问题的相应措施。
Based on a signal system test of Tianjin Metro Line 5 as the background,this paper analyzes that after the signal on-board system software is upgraded,the train turns back on the track due to the large deviation between the gravel ballast bed line slope and the slope parameter in the software database.The train triggers emergency braking to affect the operation order,and proposes corresponding measures to avoid such problems.
