Rail inspection system and method

Abstract

The invention provides a rail inspection system and method; the system applied to an operating train comprises image acquisition modules, an inertial module, an encoding module and a processing module; the image acquisition modules are arranged on two sides of an inspection beam of the operating train and are used for acquiring section images of a steel rail; the inertial module is arranged at the center of the inspection beam and is used for measuring attitude parameter information of the inspection beam relative to the steel rail when the operating train runs; an encoder is disposed on an axle of the operating trail and is used for acquiring displacement information of the operating train; the processing module is in communication connection with the image acquisition module, the inertial module and the encoder and is used for calculating according to the section images of the steel rail, the attitude parameter information and the displacement information to obtain unevenness geometric parameters of the rail, and for acquiring rail maintenance information according to the unevenness geometric parameters of the rail.

Description

technical field [0001] The invention relates to the field of track detection, in particular to a track detection system and method. Background technique [0002] The development of track detection technology has a long history. Especially since the 1970s, many developed countries such as Europe, the United States, and Japan have successively studied various advanced track detection technologies, adopted new measurement principles, and developed modern high-tech equipment. The rail inspection car improves the detection accuracy and speed, and increases the detection function. In order to meet the needs of line speed increase and high-speed development, the further developed high-speed rail inspection vehicles have played an important role in improving the smoothness of the track and ensuring the safety and comfort of train operation. After years of research and development, the Institute of Infrastructure Testing of the China Academy of Railway Sciences has developed four te...

AI Technical Summary

Problems solved by technology

2. The track detection system of analog signal transmission, when detecting the train passing the phase point, the system is often interfered by the train electricity, which affects the detection data results

3. The existing track detection system uses the car body as the inertial reference. This structure determines that its sensor layout is scattered. The system has more discrete hardware units and hardware signal processing units, and there are many fault points, which reduces system reliability and increases System overhaul and maintenance workload
