Abstract

The invention discloses a high-speed train tracking running curve optimization setting method. According to the characteristic of 'movable and dynamic length' of a tracking section of a high-speed train under movable blocking condition, the method establishes a high-speed train echo state network speed prediction model, a movable blocking based tracking running model, a line network and a tracking running curve multi-target setting model adopting innovative evaluation indexes based on line and high-speed train running data acquired in a site; an efficient multi-target particle swarm optimization is adopted to use an algorithm convergence condition as one of model setting constraints, and high-speed train tracking running curve optimization setting is performed based on the real-time data; finally, section operation efficiency and stability are used as the evaluation indexes of the setting method, and a group of optimal running curves are screened out, so that the high-speed train running process is safe and efficient, and meanwhile the high-speed train section operating efficiency and stability under the movable blocking condition are improved.

Description

technical field [0001] The invention relates to an optimal setting method of a "speed-mileage" curve of a high-speed train under a moving block, and belongs to the technical field of high-speed train tracking operation optimization control and automatic driving. Background technique [0002] With the rapid development of society, the demand for transportation continues to increase, and high-speed railway transportation has highlighted its important position in the development of the national economy. According to the national "13th Five-Year Plan for Railways", the "13th Five-Year Plan" is still a golden period for the development of railway construction. my country will accelerate the development of passenger high-speed railways and strive to improve the national high-speed railway network. In the high-speed and high-density operating high-speed railway system, the optimal control of high-speed train tracking operation based on moving block is one of the core technologies t...
