Abstract

The invention discloses a train-braking impulse control method. The train-braking impulse control method relates to a train pipe arranged on a train, a controller, a pipe communicated with the train pipe, a pressure sensor arranged on the pipe, an AD convertor, a processor, an electromagnetic valve arranged at the back portion of an air discharging opening of the pipe and a driving circuit of the electromagnetic valve; the signal output end of the pressure sensor, the AD convertor, the processor, the electromagnetic valve of the driving circuit are sequentially and electrically connected; the controller is electrically connected with the processor. The train-braking impulse control method has the advantages that the pulse separation and the pulse width can be calculated according to variation of pipe pressure, and the train can reduce pressure at the stable rate.

Description

technical field [0001] The invention relates to the technical field of rail vehicle braking, in particular to a pulse control method for train braking capable of realizing stable wind exhaust and speed control. Background technique [0002] The braking method of rail vehicles mainly adopts the air brake system. During the operation of the vehicle, the driver manipulates the brake valve to discharge the air in the train pipe, so that the pressure of the train pipe decreases, and the brake of the vehicle is controlled to achieve the purpose of deceleration and parking. [0003] When the vehicles are formed into a train, the train pipes of each car are connected into one body, and the pressure in the train pipe is controlled by the locomotive driver to achieve the purpose of controlling the synchronous braking and relief of the whole train. [0004] The on-board train control equipment is a kind of on-board safety equipment configured on the locomotive. It mainly includes GYK, ...
