城市轨道交通延伸线信号系统贯通方案

Signal Systems Connection Plan for Extension Lines of Urban Rail Transit

延伸线信号系统与主线信号系统实现贯通是影响地铁开通运营的关键因素,以苏州轨道交通2号线信号系统为例,介绍信号系统贯通测试的关键环节,以实现在不中断主线正常运营的前提条件下,实现延伸线与主线的贯通运营的目标,为后续分段开通线路提供指导和参考经验。

The connections between the signal system of the extension line and that of the existing line are a key factor affecting the operation of subways. Taking the signal system of Suzhou Rail Transit Line 2 as an example, this paper introduces the key link of the test on signal system connections in order to realize the goal of operating both the extension line and the main line after they are connected without interrupting the normal operation of the existing line, and to provide guidance, reference and experience for other lines that will start operation by separate sections.
