Embodiment Construction

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but 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 without creative efforts shall fall within the protection scope of the present invention.

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

[0033] 101. The in-vehicle device calculates, 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, corresponding to the n target points on the...

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] The ATP (Automatic Train Protection) system is an important guarantee for the safe operation of the train. The system compares the relationship between the current position and speed of the train with NBP (Normal Braking Profile, commonly used braking curve) / EBP (Emergency Braking Profile, emergency braking profile) in real time. Braking curve) These two control curves are compared to decide whether to output a braking command to prevent the train from overspeeding or rushing forward. Therefore, the design of the ATP train control curve is very important in the ATP system, which can affect the safety of train operation, the running efficiency and the comfort of passengers. [0003] At present, the maximum common braking force / maximum emergency braking force is used to calculate the vehicle...
