Abstract

The invention provides an integrated optimization method for dispatching and controlling high-speed railway trains under temporary speed limit. The method comprises the steps of configuring basic parameters of a railway line topological structure, a signal system characteristic and a train dynamics characteristic needed by optimized train operation regulating diagrams and speed curves; configuringbasic data of a temporary speed limiting scene; according to the basic parameters of the railway line topological structure, the signal system characteristic and the train dynamics characteristic anda train operation regulation and driving control integrated optimization model established under temporary speed limit conditions by the basic data of the temporary speed limit scene, adopting a mixed integer linear programming to solve the train operation regulation and driving control integrated optimization model, and obtaining the train operation regulation diagrams with locking time and thetrain speed curves. According to the integrated optimization method for dispatching and controlling high-speed railway trains under temporary speed limit, the train operation regulation diagrams withthe locking time and the speed curves can be automatically programmed and provided under the condition that a high-speed railway operation is disturbed by the condition of the temporary speed limit, the optimization performance and the feasibility of a train regulation plan and a recommended speed the operation curve can be ensured.

Description

technical field [0001] The invention relates to the technical field of train operation adjustment and control, in particular to an integrated optimization method for high-speed train dispatching and control under temporary speed limit. Background technique [0002] As a green travel mode with large capacity, low energy consumption and high efficiency, the high-speed railway system occupies an important position in the public transportation system. By the end of 2017, the total mileage of my country's high-speed railways had exceeded 22,000 kilometers. With the opening of more high-speed rail lines and the increase of train speed, the negative impact of wind, rain, snow, earthquake and other natural disasters on the safety and efficiency of train operation is becoming more and more significant. When the disaster monitoring system sends out early warning and alarm information, issuing a temporary speed limit order is an effective measure to control the speed of the train and ...
