摘要
城市轨道交通的运行主要是依靠信号系统,作为机电系统,不可避免会发生故障,在信号系统出现故障时,对行车会产生安全问题。在信号系统失效,工作人员采用人工方式控制列车运行情况下,利用无线射频(RFID)技术和红外技术,配合闭路电视监控(CCTV)系统,对列车进行定位和记录,使行车指挥人员了解列车位置、运行轨迹,从而为后续的列车运行指挥控制提供依据。从技术上和管理上,保障城市轨道交通的运行安全。
Urban rail transit relies mainly upon its signaling system, which as an electromechanical system will inevitably encounter failures. Thus, rail transit will be faced with safety problems. When the signaling system is invalid and train operation is controlled in the manual way radio requency identification （ RFIDI technology and infrared technology, in combination with closed-circuit television （CCTV） monitoring system are used to locate and record the train so that train control personnel may be informed on train position and its moving trajectory to provide a basis for subsequent train command and control. With respect to technology and management this system can ensure safe operation of urban rail transit.
