Embodiment Construction

[0024] The train braking system generally has multiple functions such as common braking, emergency braking, and parking braking. In the actual operation of the vehicle, the common braking function is used the most. Common braking generally includes electric braking and air braking. After the braking system receives the common braking command, it will give priority to applying electric braking. When the electric braking is insufficient, it will apply air braking to supplement it. In the low-speed stage of the vehicle, since the electric brake can no longer be used, the electric-pneumatic conversion will be performed at this time, and the electric brake will be completely replaced by the air brake.

[0025] Generally speaking, electric braking is given priority to the common braking of the braking system to reduce the wear of the air brake and achieve the purpose of energy saving and environmental protection. When the subway vehicle is about to enter the station, when the speed ...

Abstract

Embodiments of the present application provide a train braking method, device, electronic equipment, and storage medium, which are applied to a train braking system. The train braking system includes a brake cylinder. The method includes: according to the received electro-pneumatic conversion The braking command obtains the target braking force value, and calculates the compensation momentum value of the train; after the air braking force value of the train reaches the target braking force value, pressure compensation is performed on the brake cylinder according to the compensation momentum value. Compensating the pressure of the brake cylinder by compensating the momentum value can increase the air braking force of the train, thus effectively solving the problem of the loss of braking force caused by the slow response speed of the air brake during the conversion process between electric braking and air braking. Problems, so as to meet the deceleration requirements of vehicle parking, so that the vehicle can be parked smoothly in the parking area.

Description

technical field [0001] The present application relates to rail transit technology, in particular to a train braking method, device, electronic equipment and storage medium. Background technique [0002] At present, most rail transit trains come from the electric braking force provided by the train traction system and the air braking force provided by the train braking system. The common braking, fast braking and other functions of the train all adopt the electric-pneumatic hybrid braking method. The basic principle of the electric-pneumatic hybrid braking is to use electric braking first. When the electric braking force cannot meet the braking demand, the air braking To make up for it, when the train enters the low-speed running stage and is about to stop, because the electric brake can no longer be used, the electric-pneumatic conversion will be performed at this time, and the electric brake will be completely replaced by the air brake. [0003] In the actual operation of ...
