Rail transit train formation operation control method and control system

Abstract

The invention provides a rail transit train marshalling operation control method and system, belongs to the technical field of rail transit operation control, and the method comprises steps of calculating an actual distance error according to the spacing distance and position information of two trains; obtaining distance error transformation information in combination with the actual distance error; determining a distance coupling parameter according to the actual distance error and the distance error transformation information; calculating the actual speed error of the vehicle by combining the distance coupling parameter and the speed information of the two vehicles; combining the actual speed error to obtain speed error transformation information; determining a speed coupling parameter according to the actual speed error and the speed error transformation information; according to the speed coupling parameters, the acceleration of the vehicle is controlled in real time, and the speedof the vehicle is adjusted in real time. According to the invention, the train formation operation is realized, the relative position error and speed of the train and the preceding train are ensuredto be kept within the determined precision range, the potential rear-end collision accident caused by the formation operation is avoided, and the stability of the train formation operation is improved.

Description

technical field [0001] The invention relates to the technical field of rail transit operation control, in particular to a rail transit train marshalling operation control method and control system. Background technique [0002] The characteristics of the railway system, such as large capacity, high efficiency, low energy consumption, and low pollution, have led to the rapid development of various railway systems in my country in recent years, including subway systems, high-speed railways, and heavy-haul railways. With the increasing transportation demand, such as the morning and evening peak hours of the subway system, high-speed railway festival transportation, etc., the railway system is running close to capacity saturation. How to further improve the operating efficiency of the railway system and increase the capacity of the railway system has become a new problem faced by the industry. Train formation operation is a plan to further shorten the departure time interval be...

Problems solved by technology

Existing automatic train control usually operates in the manner of tracking the time specified by the operation plan, generating a target speed-distance curve through offline optimization, and the train tracks the target speed-distance curve. There is no interactive channel between trains, and the existing automatic driving system control mode does not Applicable to train formation operation control
