摘　　要：城市轨道交通正常情况下的列车运行安全由ATP(列车自动防护)系统保障,ATP失效情况下的降级运行尚缺乏设备层面的安全保障。从技术方案、电气接口、系统定位、设备安装等方面介绍了列车辅助防撞系统。基于无线射频和声波探测技术的辅助防撞系统,在列车头、尾各设一套相同的设备,根据从列车接口电路获得的车辆状态信息,确定设备对应头尾端的不同工况和上、下行线路的不同模式,建立同一股道上后车前端和前车尾端的应答机制,实现前后列车相对距离的实时探测,为司机提供危险车距报警信息。Under normal circumstances, the safety of metro train operation is guaranteed by the automatic train protec- tion system（ATP）, but when ATP system becomes ineffec- tive, the train operation under degraded mode will need the safety guarantee at equipment level. The auxiliary anti-crash system, based on radio-frequency and sound-wave detection technologies, consists of the same set of equipment on each end of a train. In accordance with the train status informa- tion obtained from the train interface circuit, each set of this equipment will determine the working condition of the corresponding train head/end, as well as the operation mode corresponding to the northbound/southbound track. In this way, the response mechanism between the end of the front train and the head of the back train on the same track is established. The relative distance between the front and the back trains can be measured on a real-time basis and a- larms can be sent to the driver immediately upon reaching the dangerous train distance
