Train constant-speed control method and device, medium and equipment

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...

Problems solved by technology

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. The output traction force required by the system theory is too large, and then the actual output traction force of the traction system returns to normal and tends to be the traction force output required by the traction system theory. At this time, it will easily cause the train to run at an overspeed
