Abstract

The invention provides an MVB interface board card which comprises a single-layer board, a MVB interface, an MVB master control board card interface, a serial communication interface and a network interface. The MVB interface, the MVB master control board card interface, the serial communication interface and the network interface are formed in the single-layer board, the MVB interface is used for being inserted in a vehicle control unit, the MVB master control board card interface is used for being inserted in an MVB master control board card, and the serial communication interface is used for being inserted in a tested device; the MVB interface, the serial communication interface and the network interface are all connected with corresponding pins of the MVB master control board card interface. By the adoption of the MVB interface board card, the problem that an existing MVB interface board card is low in reliability is solved, and the stability of the MVB communication process is improved.

Description

technical field [0001] The invention relates to circuit technology, in particular to an MVB interface board. Background technique [0002] With the development of fieldbus technology, the process control mode of rail vehicles has developed from the original centralized direct digital control system to the network-based distributed control system. The train network and vehicle network of the rail vehicle use two communication modes, Wire Train Bus (WTB) and Multifunction Vehicle Bus (MVB), respectively. Among them, the MVB main control board is used as the main controller of the MVB communication method, and its function is to connect the standard equipment located in the same vehicle or in different vehicles to the train network, and perform data transmission through the MVB communication method. [0003] The MVB main control board is connected with each device in the vehicle through the MVB interface board. On the one hand, the MVB interface board is connected with the plu...
