城市轨道交通信号应急盘设计及其配套行车组织方法

Urban Rail Transit Signal Emergency Panel Design and Complementary Train Operation Organization Method

城市轨道交通信号的CI(计算机联锁)系统一旦发生故障,将失去对道岔的控制权,无法获知道岔状态和列车位置信息。为提高CI故障下的应急行车组织能力,提出在车站内设置信号应急盘,介绍了应急盘的设备结构及电路设计。该信号应急盘采用“应急盘监控道岔+微机监视列车位置”的方案,分析了应用应急盘可能存在的风险,并制定相关的对策措施。提出了与应急盘应用相配套的后备站控行车法,并对该方法下的基本操作规则和风险控制措施进行研究。该应急盘在实际运营生产中取得了良好的应用效果。

Once the CI(computer interlocking)system of urban rail transit signal breaks down,it will lose control of the turnout,unable to obtain the turnout status and train position information.In order to improve the train operation organization ability under CI failure emergency,it is proposed to set a signal emergency panel in the station,and the equipment structure and circuit design of the emergency panel are introduced.The signal emergency panel adopts the scheme of"emergency panel monitoring turnout+microcomputer monitoring train position:Possible risks in the application of emergency panel are analyzed,and relevant countermeasures are formulated.The backup station train operation control method that complements the application of emergency panel is proposed,and the basic operation rules and risk control measures under this method are studied.The emergency panel has achieved good application effect in actual production and operation.
