Problems solved by technology

[0010] At present, the MVB-CAN gateway products used in my country's railway industry are all foreign standard parts. Although there are related products independently developed, they are only simple replacements and substitutes. There is no MVB-CAN gateway with independent intellectual property rights for the locomotive and rolling stock industry. CAN gateway

Abstract

The invention discloses an MVB-CAN gateway based on an ARM7 core microprocessor. The invention is characterized in that the gateway comprises an MVB bus board card, a CAN bus board card, a CPU board card, a power supply board card and a backplane. The MVB board card, the CAN board card and the CPU board card are all connected by a backplane bus on the backplane, and the power supply board card provides working electric pressure for the MVB board card, the CAN board card and the CPU board card; the CAN board card is responsible for data collection and transmission of a CAN bus equipment; the MVB board card is responsible for data collection and domination of a MVB bus equipment; and the CPU board card is responsible for a central processing of the train bus and vehicle bus equipment data and the generation of ETHERNET and RS232 monitoring data flow. The gateway is a TCN network art in accord with an international standard, which is provided with the characteristics of a novel design and a high reliability etc. The gateway suits for a wide application in areas such as railroad industry etc in our country.

Description

Technical field [0001] The invention relates to an MVB network control system conforming to the TCN standard, and is an MVB network communication device with CAN communication capability. It is widely used in industrial control fields with high real-time requirements such as railway trains, subway trains and urban rail transit vehicles. Background technique [0002] With the rapid development of foreign advanced TCN network control technology, my country's electric locomotives have also begun to adopt TCN technology, that is, the collection and control of all signals on site need to be collected on the centralized control computer through the bus. However, because some door control units, monitoring units and other equipment adopt CAN bus interface, MVB-CAN gateway has become the essential key equipment of MVB network control system, which has practical significance for the technological innovation of railway locomotive industry. [0003] IEC61375-1 "Train Communication Network" (...
