Problems solved by technology

For rail vehicles equipped with non-adhesive braking devices, during the braking process, non-adhesive braking will provide the vehicle with additional deceleration independent of adhesion, which will inevitably affect the calculation of the reference speed and the identification of deceleration in the anti-skid control strategy. It may cause the anti-skid control to be judged as sliding when the track is dry and malfunction, resulting in loss of braking force

Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] At present, it is stipulated in the train control standard that when the deceleration of the tested vehicle is greater than the design deceleration, and the difference is less than 0.3m / s 2 , the anti-skid valve should not accidentally discharge air.

[0035] The original anti-skid system uses a composite matrix based on speed difference, deceleration, slip rate, etc., where:

[0036] 1) The speed difference is the difference between the wheel set spee...

Abstract

The invention provides a train anti-skid control method and device. The method comprises the steps that a train is subjected to a non-adhesion braking test, and a speed and braking force characteristic curve during non-adhesion braking of the train is obtained; the relation between the non-adhesion braking speed and the deceleration is determined according to the speed and braking force characteristic curve during non-adhesion braking of the train; and according to the determined relation between the non-adhesion braking speed and the deceleration, train anti-skid control parameters are corrected, and anti-skid control is carried out. According to the method, the anti-skid control parameters of the train are corrected according to the determined relation between the non-adhesion braking speed and the deceleration, the reference speed calculation and deceleration parameters of the train are corrected, the purpose of anti-skid protection is achieved, anti-skid misoperation is avoided, and the operation safety of the train is guaranteed.

Description

technical field [0001] The invention relates to train control technology, in particular to a train anti-slip control method and device. Background technique [0002] Rail vehicle braking includes sticky and non-sticky brakes. Non-adhesive braking can provide braking force independent of wheel-rail adhesion, meet the greater deceleration requirements of the vehicle, reduce the wear of brake pads and brake discs, and reduce the cost of vehicle use. The current anti-skid control criterion is based on the speed difference, deceleration, slip rate, etc. caused by adhesive braking. When non-adhesive braking is involved, the vehicle deceleration increases, which will affect the existing anti-skid control system and may cause anti-skid Misoperation and loss of braking force. How to solve the train anti-skid control with the participation of non-adhesive braking will directly affect the safety of vehicle operation. [0003] Non-adhesive braking refers to the braking force generate...
