Method and device for controlling train braking

Abstract

The invention discloses a train braking control method and equipment. When an emergency braking signal sent by a partial braking control unit BCU is obtained, a first penalty braking signal is generated, and a traction blocking signal is sent to the traction control unit DCU, In order to make the DCU control the traction motor output value to be the traction force lower than the preset value, send the first penalty braking signal to the first target BCU in the train, so that the BCU that did not send the emergency braking signal receives the first penalty When the braking signal is used, the corresponding air brake device is controlled to output the penalty braking force, and the first target BCU at least includes the BCU that does not send the emergency braking signal, which can increase the braking force of the whole train in the non-traction running state, The deceleration of the train increases, so that the high friction force and high loss suffered by the wheels of the unexpected emergency braking vehicle can be quickly dispersed to the wheels of other vehicles, reducing the high friction force and high loss suffered by the local wheels of the train, reducing the wheel Risk of bruising.

Description

technical field [0001] The invention relates to the field of train braking control, in particular to a train braking control method and equipment. Background technique [0002] With the development of train control technology, the train brake control technology has been continuously improved. [0003] The train is composed of multiple vehicles, and the vehicles can be divided into two types, one is a motor vehicle that provides traction, and the other is a trailer driven by a passive vehicle. In the straight-through brake control system commonly used in trains, the bogie of each vehicle is equipped with a brake control unit (BCU, Brake control unit), and each of these BCUs is connected to the train safety loop through an emergency brake hard line . When the train enters the emergency braking condition, the train safety loop is disconnected, and each emergency braking hard line loses power. After each BCU detects that the connected emergency braking hard Braking, so that t...

Problems solved by technology

[0004] However, if a certain emergency braking hard line loses power without disconnecting the train safety loop, only the BCU connected to the emergency braking hard line will trigger emergency braking, and only this BCU is located in the train The vehicle of the vehicle will perform emergency braking. At this time, the vehicle will be in a state of running with brakes, causing the wheels of the vehicle to be damaged due to excessive frictional heat
