Abstract

The invention discloses a train brake control method and equipment. The method comprises the following steps: when emergency brake signals sent by a part of brake control units BCU are acquired, generating a first punishment brake signal, sending a traction blocking signal to a traction control unit DCU so as to enable the DCU to control the traction motor to output traction force with the numerical value lower than a preset value; sending a first punishment braking signal to a first target BCU in the train; when the BCU which does not send the emergency brake signal receives the first punishment brake signal, controlling the corresponding air braking device to output punishment braking force, wherein the first target BCU at least comprises a BCU which does not send an emergency braking signal, The braking force of the whole train in a non-traction running state can be increased, and the deceleration of the train is increased, so that the high friction force and high loss of the wheelsof the vehicle subjected to accidental emergency braking can be quickly dispersed to the wheels of other vehicles, the high friction force and high loss of the local wheels of the train are reduced,and the wheel scratching risk is reduced.

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...
