Abstract

The present invention provides a catenary hard point detection method and system, including a laser, an industrial area array camera and a pantograph slide, the laser and the industrial area array camera are arranged on the side of the pantograph slide, the method includes: Fix the laser to the pantograph slide by the laser, determine the position information of the laser point on the side of the pantograph slide; use the industrial area array camera, fix the laser to the pantograph slide When the point emits laser light, obtain the monitoring image monitored by the pantograph slide; determine the displacement distance set of the laser point according to the monitoring image; For comparison, determine the corresponding laser point when the displacement distance is not less than the preset distance; determine the hard point of the catenary according to the laser point, and determine the specific position of the hard point of the catenary according to the hard point of the catenary. The invention can realize accurate detection of catenary hard spots.

Description

Technical field[0001]The present invention relates to the field of railway contact network detection, and more particularly to a hard point detection method and system for contact network.Background technique[0002]At present, the detection of the skateboard structure is mainly used for artificial inspection. The defects of the carbon slider are mainly observed, or the contact measurement method is used, and the pressure sensor and acceleration sensor are applied to the electrical bow, and the power-receiving bows are measured. The stress and acceleration of the bow is a hard point.[0003]The drawings of the above methods are:[0004]1. Manual inspection cost, time consumption, the testing process needs to be occupied, the test time is subject to the runtime limit.[0005]2, the contact measurement needs to be modified, adding pressure sensors, and acceleration sensors, etc., which may have hidden dangers and risks for the structure and strength of the originally powered bow.Inventive con...
