WTB/MVB (Wire Train Bus/Multifunction Vehicle Bus) train communication gateway

Abstract

The invention provides a WTB / MVB (Wire Train Bus / Multifunction Vehicle Bus) train communication gateway, comprising a train bus WTB communication module which is used for collecting and controlling WTB data; a multifunctional train bus MVB communication module which is used for collecting and controlling MVB data; and an embedded CPU module which is connected with the WTB communication module and the MVB communication module through external expansion parallel buses and is used for processing the WTB data and the MVB data and outputting corresponding monitoring data streams, wherein the WTB communication module, the MVB communication module and the embedded CPU module are integrated on a standard board card, so the WTB communication module, the MVB communication module and the embedded CPU module are mounted in a central control unit case conveniently, and power is supplied by a backboard bus of the central control unit case. According to the WTB / MVB train communication gateway, a modular design is employed; the application is flexible; the standard board card is convenient for integration into the standard case; and the coordination work of other components of the train network control system can be improved.

Description

technical field [0001] The invention relates to the technical field of train network control systems, in particular to a WTB / MVB train communication gateway. Background technique [0002] The train network control system is one of the core subsystems of high-speed EMUs. Like the human brain, it directs the various subsystems of the train to work in harmony to ensure the safe, stable and fast operation of the train. At present, most of the high-speed EMUs operating at home and abroad adopt the TCN (Train Communication Network, Train Communication Network) technology stipulated in the international train network communication standard IEC61375-1 to realize the data communication of the train network control system. The TCN network adopts a two-level bus structure of WTB and MVB: a train-level WTB (Wire Train Bus, train bus) and a vehicle-level MVB (Multifunction Vehicle Bus, multifunctional vehicle bus) two-level bus. The two-level bus communicates through the WTB / MVB train ...
