Embodiment Construction

[0025] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0026] In this embodiment, as figure 1 The six-group railcar shown is illustrated.

[0027] Such as figure 1 As shown, a railway vehicle communication network includes multiple controllers, each carriage is provided with a controller, and every two adjacent controllers are connected by two buses, the bus adopts half-duplex mode, and two The buses are completely independent, each transmits its own data, and the data content transmitted by the two buses is the same. Each controller is equipped with four bus ports, which are respectively named "A, B, C, D" ports. The four bus ports are respectively connected to the bus to form a trapezoidal communication network. The controller receives the data transmitted by the adjacent controller and forwards it. Data transfer to another adjacent controller.

[0028] Such as figure 2 As shown, each contro...

Abstract

The invention relates to a railway vehicle communication network. A controller is arranged in each compartment, every two adjacent controllers are connected through a bus, each controller immediately replies after receiving data of the adjacent controller, and the self data of the controller or the data, received by the controller, of other controllers is transmitted back; a public storage module is arranged in each controller, in addition, each bus port arranged on the controller is respectively connected with the public storage module, and each controller transfers the received data to another adjacent controller after storing data transmitted from the adjacent controller into the public storage module. The railway vehicle communication network has the advantages that the dynamic transmission mode is formed in the whole communication network, and the data transmission speed is accelerated.

Description

technical field [0001] The invention relates to a communication network, in particular to a railway vehicle communication network. Background technique [0002] Usually, the data transmission of railway vehicles is transmitted through the data bus that runs through the whole car. Controllers are installed on the front and rear cars of the car. The instructions of the controller are transmitted to the equipment of each car through the bus. Usually two buses are set up to form a dual cable redundancy method, but this method can only deal with a single point of failure, that is, if one bus fails, it can be switched to the second bus to continue transmitting data. Simultaneous failure, the system will face paralysis, and when this method fails, it will take time to switch from one way to another. For example, the previously filed and published application number is 200710126385.6, which is called the patent of railway car transmission device, which proposes an improvement to t...
