A pantograph sliding plate wear state monitoring system and method

Abstract

The embodiment of the present invention provides a pantograph slide wear state monitoring system and method, the system includes: storage monitoring switch, car number identification module, roof monitoring module, monitoring center equipment, wear monitoring module and horn monitoring module; The warehousing monitoring switch is used to detect the state of the train warehousing; the wear monitoring module obtains a plurality of cross-sectional digital coordinate information of the skateboard when the pantograph is raised, and obtains the cloud map information of the skateboard; According to the structure and shape information of the horns of the pantograph, the cloud image information of the skateboard is reconstructed according to the shape information of the horns of the pantograph to obtain the real three-dimensional structure information of the skateboard; the monitoring center equipment uses the real three-dimensional structure information of the skateboard to The wear monitoring result is calculated based on the plane where the upper surface of the bow horn is located, and the remaining life of the skateboard is predicted according to the recent wear law. The obtained data is not disturbed by common interference factors, thereby realizing accurate and efficient detection.

Description

technical field [0001] The invention relates to the technical field of traffic engineering detection, in particular to a system and method for monitoring the wearing state of a pantograph slide plate. Background technique [0002] At present, all rail transit trains obtain electric energy from the outside through the sliding contact between the train pantograph and the catenary, and the sliding plate of the pantograph is the key equipment that affects the quality of current flow between the pantograph and the catenary. In order to obtain better current quality, on the one hand, the pantograph can maintain contact with the contact wire through the slide plate at high speed, which has good electrical conductivity; on the other hand, in order to prolong the service life of the contact wire, the pantograph and contact Always allow the slide to wear as much as possible during the mechanical contact of the wires. Therefore, pantograph slides have become consumable parts in the da...

Problems solved by technology

This solution is greatly affected by weather, light, camera cleanliness and resolution, and usually has large test errors, which cannot meet the needs of refined production and operation and maintenance. Therefore, at this stage, it is mainly through manual inspection by specialized technicians, Register to determine whether it needs to be replaced, but manual detection will inevitably lead to missed detection and unnecessary repeated detection, and for safety reasons, the pantograph slide plate is often replaced in advance
