Problems solved by technology

Therefore, in the actual operation process, the braking deceleration of each vehicle of the freight train may be inconsistent. The longitudinal impact force of the train is relatively large, and the longer the train, the more obvious the longitudinal impact force. accident, endangering driving safety

Abstract

The invention discloses a goods train brake control system and method with inclination participation, and relates to the technical field of vehicle brake control. The control system comprises a brakesignal sending device used for sending out a brake deceleration instruction and brake force output devices installed on all vehicles, and the brake force output devices of all the vehicles are provided with inclination sensors and can detect the inclination of the vehicles in real time. Each braking force output device is in communication connection with the braking signal sending device, can receive the brake deceleration instruction sent by the brake signal sending device, and can calculate a braking force required by each vehicle in real time according to the brake deceleration instructioninformation and the vehicle inclination information so as to control vehicle braking. By implementing the technical scheme, an influence of a component force of the gravity of each vehicle parallel toa ramp on the braking rate of the vehicle can be eliminated so that the braking deceleration of the vehicle tends to be consistent in real time, and purposes of reducing a longitudinal impact force during train braking and ensuring train operation safety are achieved.

Description

technical field [0001] The invention relates to the technical field of vehicle braking control, and more specifically, to a freight train braking control system and method with gradient participation. Background technique [0002] Usually, the braking device of each car of the freight train is set in advance according to the requirement that the braking rate is consistent on a straight road. That is to say, the braking device of each car of the current freight train is designed according to the principle that the braking deceleration of each car on a straight road is consistent, which can reduce the speed of the train when braking on a straight road. longitudinal impact. [0003] However, freight trains are generally long, and in actual operation, the terrain of each vehicle may be different, and some vehicles may be on a flat road, while other vehicles are going uphill or downhill at the same time. Since the component force of vehicle gravity parallel to the ramp will par...
