The invention relates to the field of motor train unit train data control, in particular to an Ethernet-based train-level data control method, which comprises the following steps of: setting a whole train as a network unit by optimizing a network topology structure, and communicating adjacent carriages through a vehicle-level Ethernet line, the CCU judges whether the train is in single-marshalling operation or reconnection operation, if the train is in single-marshalling operation, all control data of the CCU is not forwarded through the ETBN, and all data of subsystems in all carriages are transmitted through the ECNN; and if the vehicle is in reconnection operation, the train-level data of the CCU is forwarded to the reconnection train set through a train-level Ethernet switch ETBN. The method has significant significance in application of the single marshalling, can effectively avoid the influence on the operation of the single marshalling vehicle due to the fault of the train-level Ethernet switch, and improves the operation quality of the vehicle; and meanwhile, the configuration number of the CCU and the ETBN can be reduced, so that the vehicle cost is reduced.

    本发明涉及动车组列车数据控制领域,具体涉及一种基于以太网的列车级数据控制方法,该控制方法通过优化网络拓扑结构,将全车设置为一个网络单元,相邻的车厢与车厢之间通过车辆级以太网线路连通,由CCU判断列车处于单编组运行还是重联运行,若车辆处于单编组运行,则CCU的所有控制数据不经由列车级以太网交换机ETBN转发,各个车厢内子系统的数据全部通过ECNN进行传输;若车辆处于重联运行时,则CCU的列车级数据经由列车级以太网交换机ETBN转发到重连车组。该方法对单编组运用具有显著意义,能够有效避免因列车级以太网交换机故障对单编组车辆的运行造成影响,提高车辆的运营质量;同时,能够减少CCU和ETBN的配置数量,从而降低车辆成本。
