Abstract

The invention provides a steel rail analysis early warning model construction method and system based on big data. The method includes: extracting the existing work section data to form a one-meter precision meter, associating a steel rail related ledger table; forming a complete data model, completing the setup of a data warehouse; based on the big data advantage of the data warehouse, establishing an analysis early warning model for the data in the data warehouse by using a time sequence and logistic regression; obtaining prediction values of steel rail state related parameters in a period of time in the future by analyzing the early warning model, comparing the prediction valueswith a set threshold value, obtaining decision guidance information about whether maintenance is carried out or not, and achieving automatic analysis and early warning of steel rail safety. The analysis and early warning accuracy can be effectively improved, the prediction period is shortened, automatic maintenance and overhaul plans are established, intelligent equipment maintenance is realized, and the safety and reliability of railway operation are practically guaranteed.

Description

technical field [0001] The invention relates to the technical field of rail detection, in particular to a method and system for constructing a rail analysis early warning model based on big data. Background technique [0002] Railway public works infrastructure is an indispensable technical equipment in railway transportation, mainly including tracks, roadbeds, bridges, tunnels, etc., generally accounting for about 60% of the value of fixed assets in railway transportation. The working characteristics of railway public works equipment are different from general engineering structures. They have the characteristics of randomness and repetition of load, combination and scattered structure of structure, and regularity and periodicity of maintenance and repair. Due to the influence of train load and natural environment during use, fatigue, permanent deformation, deterioration and damage will inevitably occur. In order to keep the railway public works equipment in good condition ...
