Embodiment Construction

[0054] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0055] figure 2 It is a schematic diagram of the train MVB network system according to the embodiment of the present invention. In this embodiment, the bus management device 210 installed in the locomotive is connected to the train-level MVB bus 220 . The vehicle relay device 230 is arranged in each car, and is used for connecting the train-level MVB bus 220 and the vehicle-level MVB bus 240 . The bus management device 210 is respectively connected to the relay device 230 of each vehicle through the control line 250 to control the relay device 230 to open or close. The bus management device 210 is also connected to the switch device of the console via the control line 260 to receive instructions from the operator.

[0056] When the relay device 230 is in the d...

Abstract

The invention discloses a method and bus management device for configuring MVB networks and relays. The method comprises the steps of receiving a network configuration signal from a control console switching device, disconnecting the vehicle-level MVB networks to isolate all the vehicle-level MVB networks from one another, detecting target vehicles needing network configuration according to the network configuration signal, and connecting the MVB networks of the target vehicles so as to carry out network configuration on network devices in the target vehicles. The bus management device comprises a configuration switching interface unit, a vehicle switching interface unit, an MVB communication unit and a central processing unit, wherein the central processing unit switches off the relays in the target vehicles through the vehicle switching interface unit to be connected with the MVB communication unit and the MVB networks of the target vehicles so as to carry out network configuration on the network devices in the target vehicles.

Description

technical field [0001] The invention relates to the technical field of train control networks, in particular to a method for configuring an MVB network, a bus management device and a relay device. Background technique [0002] The TCN train communication network is composed of MVB vehicle bus and WTB twisted train bus two-level bus, and the two-level buses are interconnected through gateways. Among them, the MVB network is used to implement serial data communication between network devices located in the same vehicle or in different fixedly connected vehicles. [0003] On the other hand, an MVB-M (MVB in multiple-unit vehicle) network may also be used as the vehicle network. Such as figure 1 As shown, a single medium of MVB can be used to replace two different mediums of train level and vehicle level, and the MVB network of each vehicle is connected to the train level MVB network through the repeater of each vehicle. Because this scheme does not have the initial operation...
