Locomotive and multi-network communication interface microcomputer control device thereof

Abstract

The invention discloses a multi-network communication interface microcomputer control device of a locomotive. The control device comprises a microcomputer case, a control backboard arranged in the microcomputer case, a control daughter board arranged on a front panel of the microcomputer case and an MVB interface arranged on the control daughter board, and the control daughter board is in signal connection with the control backboard through a flexible flat cable. The control daughter board is arranged on the front panel of the microcomputer case, and the MVB interface is arranged on the control daughter board, so that the wiring of the MVB interface is very convenient, and the disassembly, assembly and maintenance operation of the control daughter board can be conveniently achieved. Besides, the control daughter board is separated from the direct connection of the control back board, and the data communication between the control daughter board and the control back board is realized byusing the flexible flat cable, so that the control device is more suitable for a narrow installation space in the microcomputer case, the occupied space on the control backboard is reduced, and the interface layout on the control back board is facilitated. The invention further discloses the locomotive which has the above beneficial effects.

Description

technical field [0001] The invention relates to the technical field of rail transit vehicles, in particular to a multi-network communication interface microcomputer control device for locomotives. The present invention also relates to a locomotive comprising the above-mentioned multi-network communication interface microcomputer control device. Background technique [0002] With the development of China's machinery industry, more and more rail transit vehicles have been widely used. [0003] There are many types of rail transit vehicles, mainly including locomotives, subways, passenger and freight trains, high-speed rails, and light rails. With the further development of railway vehicles informatization and intelligence, MVB (Multifunction Vehicle Bus) is usually installed on locomotives. MVB is a kind of interconnection equipment that is mainly used for interoperability and interchangeability. The serial data communication bus between the MVB protocol is currently an impo...

AI Technical Summary

Problems solved by technology

However, this structure still has the following problems: After the EMD (Electrical Middle Transfer, electrical middle-distance transmission) interface is made into a sub-board and the backplane is overlapped, the height of the two DB9 connectors of the MVB interface is much lower than that of the chassis The height of the panel leads to defects in the installation and disassembly of the DB9 plug in the MVB socket, the way of force, and the electromagnetic compatibility

In addition, the MVB interface and the sub-board need to occupy a certain space on the backplane, which is not conducive to the layout of the interface on the backplane, and is not conducive to the fixing of outgoing lines and wiring harnesses. Operations such as connecting the MVB interface and disassembling and maintaining the sub-board are difficult there is an inconvenience
