Abstract

The invention discloses an ARM7-based MVB gateway and a working method thereof. The gateway comprises an MVB bus protocol controller, an MVB bus transceiver, an ARM7 central controller, a DeviceNet bus protocol controller and a Device Net bus transceiver, wherein the ARM7 central controller is bi-directionally connected with the MVB bus protocol controller and the DeviceNet bus protocol controller respectively; the MVB bus protocol controller is bi-directionally connected with the MVB bus transceiver; and the DeviceNet bus protocol controller is bi-directionally connected with the DeviceNet bus transceiver. Through the ARM7-based MVB gateway and the working method thereof, the data exchange between the MVB bus protocol controller and the DeviceNet protocol controller is realized by using the ARM7 central controller, and the interconnection problems of DeviceNet field buses of an MVB control network and a widely-used industrial control network special for a locomotive.

Description

technical field [0001] The invention relates to a data conversion device between different network buses, in particular to an ARM7-based MVB gateway and a working method thereof. Background technique [0002] DeviceNet field bus is the world's leading supplier of automation control and information solutions - the optimal industrial control network technology - the underlying network of NetLinx launched by Rockwell Automation (Rockwell Automation). DeviceNet has the advantages of openness, low price, reliability and high efficiency, and is especially suitable for the bottom layer control of industrial sites with high real-time requirements. DeviceNet is now listed as the international standard IEC62026-3 (2000-07) low-voltage switchgear and control equipment - controller - equipment interface, and is included in the European standard EN50325. In addition, DeviceNet is actually the DeviceNet standard in Asia and America. [0003] In recent years, with the rapid development o...
