Pantograph slide plate condition monitoring system and method thereof

Abstract

The embodiment of the present invention provides a pantograph slide plate condition monitoring system and method thereof, the system comprises: an inbound monitoring switch, a train number identification module, a train roof monitoring module, a monitoring center device, an abrasion monitoring module and a horn structure monitoring module; wherein the inbound monitoring switch is configured to detect a train inbound state; the abrasion monitoring module acquires a plurality of slide plate cross-section digital coordinate information when a pantograph is raised, and obtains slide plate cloud map information; the horn structure monitoring module acquires shape information of the pantograph's horn structure, and reconstructs the slide plate cloud map information according to the shape information of the pantograph's horn structure, to obtain real three-dimensional structure information of the slide plate; and the monitoring center device calculates the abrasion monitoring result based ona plane of the upper surface of the pantograph horn, according to the real three-dimensional structure information of the slide plate, and predicts remaining life of the slide plate according to rules of recent abrasion. The acquired data is not interfered with common interference factors, thus accurate and efficient detection is achieved.

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
