Abstract

The invention discloses a contact line wear detection device. The device comprises: a first image collection unit and a second image collection unit, which are both disposed under a contact line, respectively collect images of the contact line from different positions, and coincide in an image collection region on the contact line; an image processing unit, which recognizes wear edge points according to the images of the contact line, and determines position information of the wear edge points; and a calculation unit, which calculates the wear amount of the contact line according to the position information of the wear edge points. Compared with existing manual detection methods, the device can greatly improve contact line wear detection efficiency, and avoid missed detection.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a contact wire wear detection device. Background technique [0002] Catenary power supply is one of the two commonly used power supply network methods for electrified railways. In the case of catenary power supply, the power supply is supplied through the contact between the pantograph above the train and the catenary. In this power supply mode, even if it falls in the track area, it is impossible to get an electric shock, and the safety is high. Therefore, the catenary power supply method is widely used in high-speed rail , bullet trains and subways. [0003] When performing catenary power supply, the pantograph is in contact with the catenary. With the extension of the service time of the catenary, the contact wire will inevitably wear out, which will seriously affect the quality and safety of power supply. Therefore, it is necessary to timely monitor the wear of t...
