地铁信号系统地面信号机常态显示方案分析

Analysis of Ground Signal Normal Display Program in Subway Signal System

移动闭塞信号系统已经逐渐成为城市轨道交通信号系统的主流方案。这种脱离传统轨道电路闭塞制式的技术给传统的信号机显示意义也带来了不小的冲击。对信号机常态点灯与灭灯方案进行了讨论,详细分析了它们的原理及优缺点。点灯方案虽然实现起来有难度,但能够更好地实现移动闭塞信号系统与信号机的匹配。但是,到底是采用常态点灯方案还是常态灭灯方案仍需根据工程实际情况进行选择。

CBTC system has gradually become the mainstream of urban rail transit signal system,this block system divorced from traditional track rcuit gives large impact on traditional cisignal display and indication significance.In the paper,consideration is given to problems of the lighting mode and the offmode,the principle,advantages and disadvantages of the two programs are analyzed in detail.Although the lighting mode is more difficult to display,it can match with the block system and signal better.In the end,a suitable program should be selected in accordance with the actual situation of the project.
