重庆单轨三号线信号系统ATP设备故障时的系统动作及应对方案

重庆单轨交通三号线信号系统ATP子系统具有各种诊断功能，当检测到故障时自动向ATP维护终端发送报警信息并对各种故障进行管理。特别是对故障会给列车运行带来障碍的设备，构成冗余系统，主备机之间相互监视状态。当单套设备故障时，系统能正常工作；当双套设备故障时，系统根据故障范围进行故障导向安全的动作。本文描述了ATP设备发生故障时的系统动作及应对方案。

System Motion and Response Scheme of Signal System ATP Equipment Failure of Chongqing Monorail Line No.3

The ATP subsystem of signal system of the Chongqing monorail traffic line No.3 has diagnosis function that when it detects failures the system can automatically send alarm reports to the maintenance terminal and manage various failures. Especially for the equipment that failures can affect the train＇s operation, the ATP system can structure redundancy system, and the host and standby supervises each other. If one of them fault, the system can work normally, otherwise, if both of them fault, the system can switch from fail to safe according to the range of the failure. In this article the system motion and response scheme are described as the ATP equipment has brokendown.
