A track state intelligent inspection device and method

Abstract

The invention relates to an intelligent rail state patrolling device and method. The patrolling device comprises a camera shooting unit, a control unit and a data analyzing and processing unit, wherein the camera shooting unit comprises a light source, a liner camera and a laser displacement sensor; the light source is used for providing illumination; the liner camera takes photos and collects rail plane image data under the control of the control unit; the laser displacement sensor collects rail vertical direction displacement data under the control of the control unit; the data analyzing and processing unit receives the collected rail plane image data and the rail vertical direction displacement data under the control of the control unit, and a 3D modeling technology is adopted to perform data synthetizing on the rail plane image data and the rail vertical direction displacement data to form a rail perspective mold, so that a three-dimensional perspective drawing of real rail state is output, and patrolling is convenient. According to the patrolling device provided by the invention, the rail plane image data and rail vertical direction displacement data are collected at the same time, and a manner of a mold is adopted to restore the complete and continuous real rail state, so that the efficiency, the accuracy and the reliability of rail patrolling are improved.

Description

technical field [0001] The invention relates to the technical field of track detection, in particular to an intelligent inspection device and method capable of efficiently and accurately detecting track states. Background technique [0002] As an important part of the comprehensive transportation system and a major livelihood project, railways have made important contributions to my country's economic and social development. According to my country's "Twelfth Five-Year" Comprehensive Transportation System Plan, by the end of 2015, the national high-speed railway network based on the "four vertical and four horizontal" high-speed railways will be basically completed, and the central and western road network framework will be accelerated. The national railway operating mileage is more than 120,000 kilometers, ranking second in the world, of which high-speed railways are about 18,000 kilometers, accounting for more than 50% of the world's high-speed railway operating mileage, r...
