Embodiment Construction

[0031] 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 creative efforts fall within the protection scope of the present invention.

[0032] An embodiment of the present invention provides a train control method, such as figure 1 shown, including the following steps:

[0033] 101. The on-board device calculates the n target points corresponding to the preset reference vehicle control curve according to the preset weight function, the current speed of the train, the predetermined target speed of the train, and the speed of the n target points before the train reaches the predetermined target speed...

Abstract

The embodiment of the invention discloses a train control method and automatic train protection equipment, relating to the field of train control and aiming to effectively prevent a train from going forward prematurely under the disturbance situation and enhance the safety of the train. The method comprises the following steps of: calculating weights corresponding to n target points on a reference train control curve according to a preset weight function, a current speed of the train, a preset target speed of the train and the speeds of n target points before the train reaches the preset target speed; calculating points on the target train control curve according to a preset traveling target position of the train, a preset target speed, a calculated step length, the weights of the n target points on the reference train control curve and the position of a train pattern drawing point; and braking the train by using the target train control curve. The method and equipment are mainly applied to train control.

Description

technical field [0001] The invention relates to the field of train control, in particular to a train control method and automatic train protection equipment. Background technique [0002] ATP (Automatic Train Protection, automatic train protection) system is an important guarantee for the safe operation of trains. Braking curve) These two control curves are compared to determine whether to output a braking command to prevent the train from overspeeding or rushing. Therefore, the design of the ATP control curve is very important in the ATP system, which can affect the safety of train operation, driving efficiency and passenger comfort. [0003] At present, the maximum normal braking force / maximum emergency braking force is selected to calculate the vehicle control curve. During the braking process, the train is affected by the braking force, basic resistance and additional resistance: among them, the braking force is related to the speed of the train, which can be obtained ...
