Abstract

The disclosure provides an existing railway alignment evaluation method and system, which relate to the technical field of rail transit. In the method and system, by obtaining multiple types of state data of train operation within a preset time period; processing each state data to obtain each processed state data; and performing correlation analysis and combination on each processed state data to obtain multiple correlation combinations; after multiple correlation combinations are obtained, the preset time period is divided into frames to obtain a plurality of first time frames after frame division, and each correlation combination in each first time frame is processed Correlation analysis, the correlation coefficient matrix is ​​obtained, and the existing railway alignment is evaluated according to the correlation coefficient matrix, which realizes uninterrupted measurement during train operation and effective evaluation of the existing railway alignment, with high efficiency.

Description

technical field [0001] The present disclosure relates to the technical field of rail transit, in particular, to an existing railway alignment evaluation method and system. Background technique [0002] At present, the maintenance work of the existing railway alignment mainly includes three parts: actual alignment evaluation, alignment reconstruction, and alignment correction and reinforcement. In the evaluation of the existing railway alignment, the geometric characteristics of the existing railway alignment are mainly obtained by engineering measurement technology, and the difference between the design alignment and the comparison is made to evaluate the state of the existing railway alignment and guide the maintenance and repair. However, this method pays more attention to the state of the existing railway alignment under static or quasi-static conditions, and the measurement period is long, so it cannot grasp the evolution state of the existing railway alignment in time. ...
