Problems solved by technology

[0003] In this way, if the rail vehicle skids, after entering the station, the skid disappears because there is no rain or snow on the track in the station, and the braking can only be completed by pure air braking, which will cause a lot of wear on the brake pads. The response timeliness and control accuracy are poor, which affects the accuracy of the rail vehicle's benchmark parking

Embodiment Construction

[0029] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] For ease of understanding and concise description, the following description will be made in conjunction with the braking control method and system for rail vehicles, and the beneficial effects will not be discussed again.

[0031] Please refer to figure 1 , figure 1 It is a flowchart of a specific embodiment of a braking control method for a rail vehicle provided by the present invention.

[0032] The braking system of a rail vehicle includes an electric braking system and an air braking system. The electric braking system applies a magnetic field force of reverse rotation to the motor to increase the rotational resistance of the motor to achieve the purpose of braking the vehicle. Here The motor is the motor that drives t...

Abstract

The invention discloses a railway vehicle brake control method and system, and the method comprises the following steps: S1, judging whether the railway vehicle slides or not through an air brake system, and if yes, entering the step S2; S2, cutting off braking of the electric braking system, providing braking force by an air braking system, performing anti-skid control, judging whether sliding ofthe rail vehicle is relieved or not, and if yes, executing the step S3; and S3, recovering braking of the electric braking system. According to the railway vehicle brake control method and system, inthe braking process, the mode that electric braking is recovered after sliding is finished is adopted, the usability of electric braking is improved, abrasion to the brake pad is reduced, and meanwhile benchmarking precision can be improved.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a braking control method and system for rail vehicles. Background technique [0002] Rail vehicles are prone to skidding in rainy and snowy weather. During the braking process, when the rail vehicle skidding is detected, the electric brake is usually cut off, and the air brake is used to provide all the braking force and the anti-skid control of the pure air brake is performed. During this process, no matter whether the taxiing is over or not, the electric braking will not be triggered until the braking is over. [0003] In this way, if the rail vehicle skids, after entering the station, the skid disappears because there is no rain or snow on the track in the station, and the braking can only be completed by pure air braking, which will cause a lot of wear on the brake pads. It is poor in response timeliness and control accuracy, which affects the accuracy of parking of ra...
