Steel railroad rail breakage fault analyzing and warning method and steel railroad rail breakage fault analyzing and warning system

Abstract

The invention discloses a steel railroad rail breakage fault analyzing and warning method and a steel railroad rail breakage fault analyzing and warning system. The steel railroad rail breakage fault analyzing and warning method includes the steps of dividing a railroad line into a plurality of unit grids according to a length scaler, defining parts and events of each unit grid, and describing full-life-circle status data of a steel rail on the basis of the parts and the events; collecting and integrating the full-life-circle status data of the steel rails in each unit grid; establishing a steel rail status degradation Markov random process model for each unit grid according to the full-life-circle status data of the steel rail of each unit grid; calculating steel rail breakage probability of each unit grid in the next steel status detecting period on the basis of Markov random process model for each unit grid, assigning different threshold values to the steel rail, and warning a steel breakage fault. The steel railroad rail breakage fault analyzing and warning method and the steel railroad rail breakage fault analyzing and warning system have the advantages that by the aid of the technical scheme, calculation scale for steel rail breakage fault analyzing and warning is reduced, calculating precision is improved, and specific position and time of the steel rail breakage fault can be analyzed and warned.

Description

technical field [0001] The invention relates to the field of railway safety. More specifically, it relates to a method and system for analyzing and early warning of railway rail breakage faults. Background technique [0002] Rail breakage is one of the main factors restricting the safety and punctuality of railway traffic. On the one hand, broken rails affect the normal running of the line and cause train delays. On the other hand, it will bring the danger of derailment and overturning of trains. [0003] The fracture of railway rails is affected by comprehensive factors such as design, construction, operation, and natural environment, such as design factors such as line design and stress design of seamless lines, manufacturing and construction factors such as rail materials, laying conditions, and welding processes, and trains passing through during operation. Operating conditions such as gross weight, locomotive axle load, traffic density, train marshalling, train startin...

AI Technical Summary

Problems solved by technology

The difficulty of using the factor analysis method to analyze the fracture of railway rails is that there are too many factors to describe the fracture of rails, and many factors are difficult to quantify, resulting in too large a matrix of factor variables, difficult data collection, complex calculations and inability to exhaust all factors, and the analysis effect is great discount

[0007] Statistical law modeling generally counts the rail breakage data within the jurisdiction of a railway bureau or a public works section across the country, establishes a prediction model, and predicts the trend of the number of rail breakages. This method is difficult to determine the specific location and time of rail breakage
