According to the train head and tail vehicle-mounted signal system equipment redundancy method and system, for non-motor train modes such as a motor train unit, a dynamic set motor train unit and an urban rail train, vehicle-mounted signal systems such as ATP, LKJ and ATO and related devices and peripheral monitoring and diagnosis equipment are installed at the head and the tail of the train, and the vehicle-mounted signal equipment at the head end and the tail end is in a mutually independent state; or data interaction is carried out only through a train through line such as a communication bus or a point-to-point serial line mode, direct wireless or through line communication is carried out between the train head and the train tail, communication reliability can be improved by adopting communication means such as a relay when the train is long, and meanwhile, train-ground wireless communication is carried out between the train head and the train tail and ground equipment independently to carry out data interaction; therefore, train head and tail information sharing is realized, mutual redundancy of train head and tail equipment is realized, and availability and reliability of the system are improved.
本发明列车首尾车载信号系统设备冗余方法和系统,针对非机辆模式如动车组、动集式动车组、城轨列车等列车,列车首尾安装有车载信号系统如ATP、LKJ以及ATO等相关装置及周边监测诊断设备,且首尾两端的车载信号设备互为独立状态,或仅通过列车贯通线如通信总线或点对点串行线方式交互数据,通过列首列尾间直接无线或贯通线通信,列车较长时可采用中继等通信手段提高通信可靠性,同时或单独采用列首列尾均与地面设备间进行车地无线通信交互数据,实现列车首尾信息的共享,进而实现列车首部与尾部设备的相互冗余,提高系统的可用性和可靠性。
