Pantograph monitoring system

Abstract

The invention discloses a pantograph monitoring system, which comprises a CCD (Charge Coupled Device) camera, a laser group and a flash light group, wherein the CCD camera, the laser group and the flash light group are connected with a PLC (Programmable Logic Controller) and are controlled to be switched on/off by the PLC controller; the PLC controller is also connected with an industrial computer; and the industrial computer is connected with the CCD camera through a broadband network, and can receive, store and process photos sent by the CCD camera through the broadband network. The industrial computer is used for analyzing and processing an image of a part of the side face of the pantograph head of the pantograph, taken by using the CCD, so that the wearing situation of a sliding plate on the top of the pantograph head of the pantograph and the deformation situations of cleats on two sides can be known clearly and vividly. By adopting the pantograph monitoring system, the wearing situation of the sliding plate of the pantograph and the deformation situations of the cleats can be automatically monitored, high efficiency and high accuracy are achieved, error judgment does not occur easily, and the bow net accident is avoided more reliably.

Description

technical field [0001] The invention relates to a system for monitoring the wear condition of the sliding plate surface of the pantograph used on the roof of the rail electric traction locomotive and the deformation condition of the horn of the pantograph. Background technique [0002] A pantograph is an electrical device installed on the top of an electric traction locomotive to obtain electrical energy from the catenary. It usually consists of a bow head part, a hinge part, a chassis and a transmission mechanism. The bow head part includes a slide plate frame, a slide plate mounted on the frame, and horns on both sides of the frame. The slide plate is in sliding contact with the contact line to receive current. In order to ensure the smooth circulation of the pantograph traction current, the sliding plate on the top of the pantograph and the contact line of the catenary must be in reliable contact with a certain contact pressure. However, the pantograph travels at high sp...

Problems solved by technology

In addition, although the deformation of the horns of the bow head will not immediately affect the normal operation of the pantograph, but because it will cause the center of gravity of the entire bow to change, working in a deformed state for a long time will eventually affect the performance of the entire pantograph. From affecting the se
