地铁信号系统联锁故障时的行车安全保障措施

Traffic Safety Guarantee Measures for Subway Signal System Interlocking Fault

随着城市经济的快速发展和人口数量的增加,人们对于城际交通的要求越来越高,地铁轨道交通的出现,在很大程度上缓解了城市交通压力。但是,地铁交通运行中也时常出现一些故障问题,若不加以控制、改进,严重威胁着人们生命财产安全,例如,地铁车辆CBTC系统车载信号故障。为了更好地保障城市轨道交通车辆正常运行、安全行驶,结合着北京地铁X号线进一步探讨CBTC联锁子系统改造方案的技术可行性。

With the rapid development of urban economy and the increase of population, the demand for intercity traffic is getting higher and higher. The emergence of metro rail transit has alleviated the urban traffic pressure to a great extent. However, the subway traffic operation also often appear some fault problems, if not controlled, improved, a serious threat to people＇s lives and property safety,such as subway vehicle CBTC system vehicle signal failure. In order to better protect the normal operation of urban rail transit vehicles,driving safety, combined with the Beijing metro line X further explore the technical feasibility of CBTC interlocking subsystem reconstruction program.
