Synchronous control communication device for brake system of electric locomotive

Abstract

The invention discloses a synchronous control communication device for a brake system of an electric locomotive, which comprises a main control unit, a memory unit, a high-speed memory unit, a programmable logic unit CPLD, a CAN bus interface unit, a MVB interface unit, a synchronous RS422 interface unit and a USART interface unit, wherein the memory unit and the high-speed memory unit are connected with the main control unit respectively; the main control unit is connected with an E-P brake controller and a control system display screen through the CAN bus interface unit; the main control unit is connected with a central control unit of the electric locomotive through the MVB interface unit; the main control unit is connected with a wireless synchronizer through the synchronous RS422 interface unit; and the main control unit is connected with a braking control unit of the electric locomotive through the USART interface unit. The synchronous control communication device for the brake system of the electric locomotive has the advantages of simple structure, low cost, various bus interfaces, wide application scope, high expandability, high control precision, high anti-interference capacity and the like.

Description

technical field [0001] The invention mainly relates to the design field of braking systems on electric locomotives, in particular to a synchronous control communication device for the braking systems of electric locomotives. Background technique [0002] In order to meet the needs of the operation of large and heavy-duty freight trains, it is necessary to realize the synchronous operation of each machine workshop through a wireless communication network. In order to realize the braking synchronous function of each locomotive workshop, it is required that the matching locomotive brakes should have the function of network communication. At present, the DK-1 locomotive electro-pneumatic brake used by domestic electric locomotives cannot meet the requirements of synchronous control because it does not have network communication functions. On the basis of the original DK-1 locomotive electro-pneumatic brake, a synchronous control communication device for the locomotive brake sys...

Problems solved by technology

However, the existing communication system generally adopts an indirect communication method, that is, the braking command needs to be relayed by other devices to establish communication with the wireless device.
