Pantograph operating state monitoring method and device

Abstract

The present invention relates to a pantograph operating state monitoring method and device. The method includes: judging whether a pantograph is detected in a preset detection area, the preset detection area covering the catenary passing by the pantograph; It is assumed that when a pantograph is detected in the detection area, the three-dimensional information acquisition module is started to collect image data of the pantograph; and, the image data collected by the three-dimensional information acquisition module is analyzed and processed to construct a three-dimensional model of the pantograph, and Extract pantograph size information. This method can timely, conveniently and quickly detect the size information of the pantograph such as the thickness of the pantograph slide plate during the operation of the train, thereby ensuring that the pantograph is in normal operation and greatly reducing the risk of pantograph failure. The detection efficiency is high, and pantograph-catenary accidents caused by pantograph failures are avoided.

Description

technical field [0001] The invention relates to the technical field of rail trains, in particular to a method and device for monitoring the running state of a pantograph. Background technique [0002] The pantograph is installed on the top of the electric traction locomotive, and there is usually a sliding plate on the top of the pantograph that can slide in contact with the catenary to obtain electric energy from the catenary to provide power for the traction locomotive. In order to ensure that the pantograph can provide stable traction current, on the one hand, the length of the sliding plate is required to ensure that it can still be in contact with the catenary when the locomotive is swinging; The contact wires are in close contact, and elastic devices such as springs are usually installed at the bottom of the pantograph to push the slide plate against the contact wires, and there is a certain contact pressure between them. [0003] However, in practical applications, t...

Problems solved by technology

[0003] However, in practical applications, the pantograph travels at high speed with the locomotive, and the contact wire always slides relative to the sliding plate on the top of the pantograph during the locomotive’s moving process. The conductive material on the skateboard is worn out. Once the wear is over, the contact pressure between the skateboard and the contact wire is insufficient, resulting in a gap, and then an electric spark, which may cause a pantograph-catenary accident, or even a locomotive failure.
