The embodiment of the invention provides a train communication system. The system comprises a vehicle-mounted ATP host, a vehicle-mounted ATP standby, a main DMI and a standby DMI, the vehicle-mountedATP host is connected with the main DMI and the standby DMI through a Flex Ray bus, and the vehicle-mounted ATP standby is connected with the main DMI and the standby DMI through the Flex Ray bus; when the vehicle-mounted ATP host is in a normal working state, the vehicle-mounted ATP host is started, the vehicle-mounted ATP host transmits train operation data to the main DMI in the available state according to a preset Flex Ray protocol database; and when the main DMI is in the unavailable state, the train operation data is transmitted to the standby DMI through the Flex Ray bus according tothe preset Flex Ray protocol database. According to the embodiment of the invention, the safety, reliability and real-time performance of communication between the vehicle-mounted ATP equipment and the DMI are ensured.

    本发明实施例提供一种列车通信系统,包括:车载ATP主机、车载ATP备机、主DMI和备DMI,其中车载ATP主机通过Flex Ray总线分别与主DMI和备DMI连接,车载ATP备机通过Flex Ray总线分别与主DMI和备DMI连接;其中,在车载ATP主机处于正常工作状态时,车载ATP主机通过Flex Ray总线,按照预设Flex Ray协议数据库,将列车运行数据传输至处于可用状态的主DMI,并在主DMI处于不可用状态时,通过Flex Ray总线,按照预设Flex Ray协议数据库,将列车运行数据传输至备DMI。本发明实施例保证了车载ATP设备与DMI之间通信的安全性、可靠性和实时性。
