Monitoring method and device for operating state of pantograph

Abstract

The invention discloses a monitoring method and device for the operating state of a pantograph. The method comprises the steps that whether the pantograph is detected or not is judged in a preset detection area which covers an overhead line system where the pantograph passes; when the pantograph is detected in the preset detection area, a three-dimensional information collection module is started to carry out image data collection on the pantograph; image data collected by the three-dimensional information collection module are analyzed and processed, a pantograph three-dimensional size model is built, and size information of the pantograph is extracted. In the running process of a train, the size information of the pantograph such as the thickness of a sliding board of the pantograph can be detected conveniently and rapidly in time, and therefore it is ensured that the pantograph is in a normal running state, the fault detection efficiency of the pantograph is greatly improved, and it is avoided that due to faults of the pantograph, accidents of the pantograph are caused.

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.
