An online control method for maintaining the stability of high-speed train operation

Abstract

The invention provides an online control method for maintaining the running stability of a high-speed train, and relates to the technical field of high-speed train dispatching. This method first sets the limiting parameters of the high-speed train running process, and then obtains the actual information of the train operation time during the train operation process, and then determines the train with the operation time disturbance, the route number where the disturbance occurs, the magnitude of the disturbance, and the type of time disturbance; and then Analyze and determine all trains affected by the disturbance; analyze and determine the conflict of train operation time caused by the disturbance based on the actual information of high-speed train operation, the type of time disturbance and the trains affected by the disturbance, and then forecast the abnormal delay of the scheduling plan caused by the conflict of train operation time , to determine the degree of abnormality of the dispatching plan caused by the conflict of train operation time; finally, according to the forecast result of the abnormal delay of the dispatching plan, online adjustment is made to the dispatching plan to eliminate the conflict of train operating time in the dispatching plan.

Description

technical field [0001] The invention relates to the technical field of high-speed rail dispatching, in particular to an online control method for maintaining the running stability of high-speed trains. Background technique [0002] Under the high-speed and high-density characteristics of high-speed trains, the operation of high-speed trains puts forward higher requirements for the dynamic dispatch of high-speed rail. Dynamic dispatching of high-speed rail is the core of railway traffic dispatching and command work, and determines the quality of traffic organization work in the section. Its quality directly affects the completion of transportation tasks, especially at the current stage, when there is a contradiction between transportation capacity and transportation volume. At this time, making full use of the transportation capacity of the line can alleviate the tense situation of transportation and maximize transportation benefits. While ensuring the comfort and safety of ...

Problems solved by technology

None of the above patents has conducted an in-depth analysis of the degree of impact of the disturbance on the initial dispatch plan when there is an abnormality in the operation of the high-speed train dispatch plan, especially in the case of train operation delays. The re-scheduling method will have a great impact on the initial scheduling plan, making the initial scheduling plan unable to maintain good continuity and stability, and thus making the train diagram in the process of frequent adjustments, which is not conducive to the stability and smooth operation of high-speed trains
