Embodiment Construction

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0021] Because there are few related test instruments for MVB network, it is difficult to realize the automatic test of MVB network. The equipment using the VXI bus has rich functions and mature technology. Therefore, the mature VXI bus equipment can be connected to the MVB bus network, and the automatic test can be realized by using the functions...

Abstract

The invention provides gateway equipment which comprises an MVB network standard interface, an MVB protocol controller, a main processor, a VXI protocol controller and a VXI network standard interface, wherein the main processor is connected with the MVB protocol controller and the VXI protocol controller, is used for converting MVB data obtained through encoding of the MVB protocol controller into VXI data and sending the VXI data to the VXI protocol controller and is also used for converting the VXI data output by the VXI protocol controller into the MVB data and sending the MVB data to the MVB protocol controller. The invention achieves the purpose of interconnecting MVB bus equipment with VXI bus equipment.

Description

technical field [0001] The invention relates to the field of industrial control, in particular to a gateway device. Background technique [0002] Industrial Fieldbus is a network communication standard, which enables products from different manufacturers to communicate through the communication bus using a common protocol. Multifunction Vehicle Bus (MVB for short) based on distributed control has the advantages of strong real-time performance and high reliability, and is the recommended solution for TCN (international standard for train communication network). Due to the strong professionalism of the MVB bus, only a few manufacturers can provide related interface devices of the MVB bus. In addition, there are fewer related test instruments for the MVB bus. [0003] VXI bus is an extension of high-speed computer bus-VME bus in the field of instruments. VXI bus standard is open, compact structure, strong data throughput, up to 40MBps. It also has the characteristics of pre...
