Example Embodiment

[0033] Next, the technical solutions in the embodiments of the present invention will be described in connection with the drawings of the embodiments of the present invention, and it is understood that the described embodiments are merely the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art are in the range of the present invention without making creative labor premise.

[0034] At present, there are provisions in train control standards that when the speed of the test is larger than the design deceleration, and the difference is less than 0.3m / s. 2 When the non-slip valve should not survey.

[0035] The original non-slip system adopts a composite matrix based on speed difference, deception, slip rate, and the like, where:

[0036] 1) The speed difference is the difference between the rotation speed and the vehicle reference speed.

[0037] 2) ...

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...
