However, the PID adjustment calculates only the required output traction force of the traction system, and the train will output the actual traction force during operation. If the actual output traction force of the train traction system is too small for a short period of time, the traction force calculated by the PID adjus

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] In the prior art, the constant speed control of the train is generally based on the difference between the preset speed and the actual speed of the train to perform PID adjustment on the traction system of the train, so as to keep the train running at a constant speed. However, the PID adjustment calculates only the required output traction force of the traction system, and the train will output the actual traction force during operation. If the actual o...

Abstract

The invention discloses a train constant-speed control method. The method comprises the steps that whether a first difference value between the preset speed and the current speed of a target train islarger than a first preset threshold value or not is judged; if the first difference value is smaller than or equal to the first preset threshold value, whether the second difference value is larger than a second preset threshold value or not is judged, wherein the second difference value is the difference value between the traction force theoretically output by the traction system of the target train and the currently output traction force; and if the second difference value is larger than a second preset threshold value, the traction system is controlled to keep the currently output tractionforce, so that the target train keeps running at a constant speed. Obviously, by means of the method, the overspeed problem of the target train in the running process can be avoided. Correspondingly,the train constant-speed control device, medium and equipment disclosed by the invention also have the above beneficial effects.

Description

technical field [0001] The invention relates to the control field, in particular to a train constant speed control method, device, medium and equipment. Background technique [0002] As a common means of transportation when people travel, trains have been widely promoted around the world because of their fast running speed, safety and environmental protection. In practical applications, in the existing train constant speed control method, the traction system of the train is generally PID adjusted according to the difference between the preset speed of the train and the actual speed, so as to keep the train running at a constant speed. However, the PID adjustment calculates only the required output traction force of the traction system, and the train will output the actual traction force during operation. If the actual output traction force of the train traction system is too small for a short period of time, the traction force calculated by the PID adjustment will be reduced...
