A layout method, system, terminal and readable storage medium for intelligent reconstruction of existing track lines

Abstract

The invention discloses a layout method, system, terminal and readable storage medium for intelligent reconstruction of existing track lines. The method includes: obtaining line information of existing track lines, and constructing a reconstruction model of existing track lines; namely The model includes design variables, constraints and optimization functions, the design variables are the planar alignment information and longitudinal alignment information of the design baseline; the initial line of the design baseline for the reconstruction of the existing track line is generated; the reconstruction based on the existing track line The initial route of the model and the design baseline is optimized by an optimization algorithm to obtain the best design variable; the design route based on the optimal design variable is the layout result of the reconstruction of the existing track route. The layout method of the present invention is used to realize the intelligent reconstruction of existing track lines. Geometric constraints and bridge-tunnel constraints are considered in the layout, and multi-temporal coupling and space complex correlation constraints are effectively coordinated to obtain the optimal solution, which solves the problem of artificial experience. Disadvantages of adjustment.

Description

technical field [0001] The invention belongs to the technical field of track line reconstruction, and in particular relates to a layout method, system, terminal and readable storage medium for intelligent reconstruction of existing track lines. Background technique [0002] The railway is the infrastructure of the country, and it is also the lifeline of the national economy of our country. With the rapid development of the national economy and the continuous expansion of foreign trade, the volume of railway passengers and freight has also increased significantly year by year. Therefore, the technical equipment and transportation capacity of existing railways often cannot meet the requirements of railway modernization and traffic growth, and technical transformation and capacity enhancement are required. [0003] In order to alleviate the pressure of railway transportation and improve the quality of railway transportation, it is necessary to strengthen the construction of rai...

Problems solved by technology

However, most of the current research focuses on new railway lines, and the reconstruction of existing railway lines has the problems of multi-temporal coupling and complex spatial correlation constraints, which cannot directly apply existing optimization methods

At present, only a few studies have proposed separate reconstruction optimization methods for plane or longitudinal sections, but these methods ignore the coupling between plane and longitudinal planes. For the intelligent reconstruction of existing railway lines, there is still a research blank at home and abroad.
