摘要
[目的]既有城市轨道交通线路达到一定运营年限后,需要对其信号系统进行更新改造,应制定车辆段联锁接口方案,以实现新旧车辆段室内外信号设备的平稳过渡和无扰切换。[方法]以我国某城市轨道交通车辆段信号系统改造工程为案例进行研究,介绍了改造后新车辆段与改造前既有正线车站、既有试车线的接口方式,以及新车辆段与新正线车站、新试车线的接口方式。阐述了该改造工程新车辆段与既有正线车站的接口布置方案。在此基础上,重点分析了既有车辆段信号改造过程中新旧车辆段联锁系统的倒接方案及其实施方式、特点和风险。[结果及结论]通过实施该联锁接口改造方案,可分阶段地实现改造前后车辆段与正线车站、试车线接口连接方式的转换,确保接口连接转换的平稳过渡。
[Objective]After reaching an operational lifespan,the signaling systems of existing urban rail transit lines need updating and renovation.A depot interlocking interface scheme should be developed to achieve a smooth transition and seamless switching between indoor and outdoor signaling equipment of the new and old depots.[Method]Taking the signaling system renovation project of an urban rail transit depot in China for case study,the interface modes between the renovated depot and the existing main line station,as well as the test line before renovation,between the new depot and the new main line station,as well as the new test line are introduced.The layout scheme for the interface between the new depot and the existing main line station in the renovation project is elaborated.On this basis,the reverse connection scheme,implementation method,characteristics,and risks of the interlocking system between the new and old depots during the existing depot signaling renovation process are analyzed emphatically.[Result&Conclusion]By implementing the interlocking interface renovation scheme,the conversion of interface connection modes between the depot and the main line station,as well as the test line before and after the renovation can be achieved by stages,and a smooth transition of interface connection conversion can be ensured.
