Embodiment Construction

[0043] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0044] The technical problem to be solved in this application is to provide a dual-proportional-integral controller parking control method to make the parking position of the rail train as close to the obstacle as possible under the premise of ensuring safe operation, so as to save the design length of the parking line and improve the operating efficiency of the train the goal of. In the vehicle control part, it is undoubtedly the most important to grasp the braking point, because as a braking method with a fixed braking rate, the grasp of the braking timing is related to whether the train can be accurately stopped at the target parking point. The existing braking speed time control curve is as follows: figure 1 as shown, figure 1 It is a schematic diagram of an existing braking speed time control...

Abstract

The invention provides a double proportional integral controller parking control method and device, electronic equipment and a storage medium, and relates to the technical field of brake control. Themethod comprises the steps of obtaining a reference braking speed curve; obtaining a first output result through a first proportional integral control module based on the reference braking speed in the reference braking curve, and the first proportional integral control module being used for processing first-order speed control; obtaining a second output result based on the first output result through a second proportional-integral control module, the second proportional-integral control module being used for processing first-order acceleration rate or deceleration rate control; performing time domain conversion on the second output result to obtain an actual braking speed curve; and braking the controlled object based on the actual braking speed curve through a train automatic driving system. According to the method, through rapid level adjustment of the second-order PI, the problem that the speed value obtained through a common PI algorithm is large in fluctuation is solved, the speed is converged within a small range, and the subsequent parking accuracy is improved.

Description

technical field [0001] The present application relates to the technical field of braking control, in particular, to a dual proportional integral controller parking control method, device, electronic equipment and storage medium. Background technique [0002] In the field of rail transit / transportation and industrial control, the control system has the functional requirements of automatically controlling the train to start, run, and stop according to regulations or requirements. Automatic control of trains is generally achieved by controlling the acceleration of the traction / braking force or the rotational speed of the wheels, which is manifested as controlling the traction, coasting, and braking of the train. [0003] In some safety-critical systems in the above-mentioned fields, such as the subway system, the signal system needs to be responsible for safe driving, and various restrictions will be imposed on driving safety. Therefore, the signal system needs to protect the ...
