Automatic control method, device, equipment and system for running speed of train and medium

Abstract

The invention discloses an automatic control method for the running speed of a train. The method comprises the steps that the actual speed sent by a speed sensor and the actual acceleration sent by anacceleration sensor are received; according to the target speed and the actual speed, a speed error is calculated; according to the speed error, the reference acceleration is calculated; according tothe reference acceleration and the actual acceleration, an acceleration error is calculated; by adopting a preset control algorithm, according to the acceleration error, calculation is conducted; thecorresponding train control amount is output to a traction system or a braking system of the train, so that the actual speed is adjusted. According to the automatic control method, based on the acceleration error, the running speed of the train is automatically controlled, the control precision and robustness can be effectively improved, large vibration and sudden change of the driving speed of the train are restrained to a certain degree, and the riding comfort of passengers is improved. The invention further provides an automatic control device, equipment and system for the running speed ofthe train and a computer readable storage medium. The device, equipment and system has the same advantages.

Description

technical field [0001] The present application relates to the technical field of train control, in particular to a method, device, equipment, system and computer-readable storage medium for automatic control of train running speed. Background technique [0002] With the rapid development of my country's rail transit, the demand for high-efficiency and high-density train operations continues to grow, and the requirements for train control technology in rail transit are also getting higher and higher. Communication Based Train Control System (CBTC) Came into being. Automatic Train Operation (ATO) is one of the core systems in the train control system. It can adjust the train speed in real time to realize automatic train driving, thereby improving train operation efficiency and reducing transportation costs and driver workload. Labor intensity. In the prior art, the train automatic driving system generally performs traction or braking regulation directly based on the speed e...

Problems solved by technology

In the prior art, the train automatic driving system generally performs traction or braking regulation directly based on the speed error of the train, and because the speed signal generally has a delay problem, it will affect the final control accuracy, and the control method The robustness of the vehicle is poor, and when the speed changes suddenly or there is a large disturbance, it will seriously reduce the ride comfort of passengers
