点式模式下地铁列车运行与站台屏蔽门联动及防闯红灯的系统设计

摘要

合肥地铁1号线要求,列车在点式模式下能实现站台屏蔽门联动,在出站信号机为禁止情况下能防止司机误操作而闯红灯.为了实现该功能,增加了一套独立的车-地通信网络和一套后备情况下站台屏蔽门联动及防闯红灯设备,在列车与轨旁列车自动保护通信丢失后,在列车降级为点式模式的情况下,可实现站台屏蔽门的联动和防止闯红灯功能.%According to the requirements of Hefei metro Line 1,the train could achieve PSD synchronized control and pre-vent the train from running the red signal in case of driver′s operation error. To achieve this function,one independent ve-hicle wayside communication network equipment and one ex-tra PSD control unit are installed. When the train is reduced to intermittent ATP mode,even the vehicle wayside automatic protection communication is lost,the function of PSD linkage and prevention of running red will still be performed.
