The invention discloses a high-speed maglev train communication method, and the method is applied to a high-speed maglev train. The train comprises a first compartment and a second compartment; the first compartment comprises a first controller, a second controller and a first switch, the second compartment comprises a third controller and a second switch, and the method comprises the following steps: the first controller receives a first message sent by the second controller through a controller area network (CAN); and the first controller sends a second message to the third controller through the Ethernet between the first switch and the second switch, wherein the second message is generated according to the first message. Due to the fact that a plurality of controllers in a single train can be connected to a bus at the same time through the CAN network for communication, arrangement of communication lines in the train is reduced, due to the fact that the carriages are connected through the Ethernet, the CAN network is only used for being connected with the controllers in the carriages, the length of routing of the CAN network is shortened, the number of used repeaters is reduced, and the interlayer space of the high-speed maglev train is saved.

    本申请公开了一种高速磁悬浮列车通信方法,该方法应用于高速磁悬浮列车,列车包括第一车厢和第二车厢;第一车厢包括第一控制器、第二控制器和第一交换机,第二车厢包括第三控制器和第二交换机,该方法包括:第一控制器接收第二控制器通过控制器局域网络CAN发送的第一消息;第一控制器通过第一交换机和第二交换机之间的以太网向第三控制器发送第二消息,第二消息根据第一消息生成。由于CAN网可以将单车内多个控制器同时连接在总线上进行通信,减少了列车内通信线的布置,且由于车厢与车厢之间通过以太网进行连接,CAN网仅用于连接车厢内的控制器,缩短了CAN网走线的长度,减少了中继器的使用个数,节约了高速磁悬浮列车的夹层空间。
