Example Embodiment
[0025] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:
[0026] This embodiment passes as figure 1 The six marshalling railway vehicles shown are described.
[0027] Such as figure 1 As shown, a railway vehicle communication network includes multiple controllers. Each carriage is equipped with a controller. Every two adjacent controllers are connected by two buses. The bus adopts a half-duplex mode. The buses are completely independent, each transmitting its own data, and the content of the data transmitted by the two buses is the same. Each controller is equipped with four bus ports, named "A, B, C, D" ports, respectively, the four bus ports are connected to the bus, forming a ladder communication network, the controller receives the data transmitted by the adjacent controller and forwards it Data transmission to another adjacent controller.
[0028] Such as figure 2 As shown, each controller transmits dat...
