Symmetrical track overhead line system detection device and method

Abstract

The invention belongs to the technical field of track overhead line system detection, and discloses a symmetrical track overhead line system detection device and method. The detection device comprises a movable vehicle body used for moving on a track, a console and a detection unit are installed on the movable vehicle body, the detection unit comprises an infrared laser, an industrial personal computer and two cameras, and the console and the two cameras are respectively connected with the industrial personal computer; the two cameras form a binocular camera group and are symmetrically arranged on the two sides of the infrared laser; a noise removal module, a template matching module, an edge extraction module, a gravity center extraction module and a coordinate conversion module are arranged in the industrial personal computer. The mobile vehicle body is used as a carrier of the detection system, so that continuous detection can be realized; an image processing technology is utilized to calculate a guide height value and a pull-out value of the overhead line system, and the accuracy is at a pixel level and is much higher than that of manual detection; during operation, direct contact with the overhead line system is not needed, the field of view range is wide, the detection precision is high, and the detection efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of track catenary detection, in particular to a symmetrical track catenary detection device and detection method. Background technique [0002] The catenary is erected along the "zigzag" line above the rail in the electrified track. It is a high-voltage transmission line for the pantograph to take power. The form of transmission lines has an important impact on whether the locomotive can safely increase speed and run stably at high speed. [0003] With the rapid development of rail transit, the mileage of bullet trains, high-speed rail and subways has increased year by year, and catenary detection has become an important measure to ensure traffic safety. The current catenary detection methods are mainly divided into two detection methods: manual inspection and fixed-point installation of detection devices. , both detection methods have the problems of low detection efficiency and inability to realize contin...
