Control system and method for controlling centralized braking of train, and brake control system for motor train unit

Abstract

Embodiments of the invention provide a control system for controlling centralized braking of a train. The system comprises a pressure acquisition device and a train pipe control device, wherein the pressure acquisition device is used for acquiring a pressure of a main blast line; a pressure signal output end of the pressure acquisition device is connected with a pressure signal input end of the train pipe control device; a brake signal input end of the train pipe control device is connected with a brake signal output end of a brake controller; the train pipe control device is pneumatically connected with the main blast line and a train pipe through an air path end respectively. According to the scheme, the mounting space of a trailer and the cost are reduced. Moreover, because an automaticbrake control system is adopted to control pressure changes of the train pipe, a train can be linked with a passenger carriage adopting automatic air braking for operation, and the pressure changes of the train pipe and five-wire system control signals are controlled according to a brake request output by the brake controller and detection of a real-time pressure of the train pipe, thus realizingflexible formation.

Description

technical field [0001] The invention relates to rail traffic control technology, in particular, to a centralized braking control system and method for controlling vehicles and a braking control system for an EMU. Background technique [0002] Passenger trains operating in China are mainly divided into two categories according to the grouping form, one is the form of locomotive + passenger car, and the other is the form of EMU. [0003] The braking control system in the form of locomotive + passenger car mainly refers to the braking control system of the locomotive. At present, the automatic braking control system controlled by the microcomputer is widely used in the locomotive. Command, precisely control the train pipe pressure, and transmit the train braking demand through the change of the train pipe pressure. The passenger car adopts an automatic electro-pneumatic brake, which generates the corresponding brake cylinder pressure according to the pressure change of the tra...

AI Technical Summary

Problems solved by technology

[0006] This existing EMU brake control system needs to be equipped with a brake control unit on each car, which is expensive, and the EBCU and PBCU are integrated in one box, which is relatively large

And it can't run in conjunction with passenger cars that use automatic air brakes

The braking command is transmitted through the network, limited by the network, the braking system cannot be flexibly organized
