Abstract

The invention discloses a pantograph slide plate detection method and device. An image of a pantograph slide plate can be obtained in real time, the upper and lower edges of the pantograph slide plate are recognized from the image based on image recognition, the real contour of the pantograph slide plate is obtained, and thus, the abnormal wear condition of the pantograph slide plate can be accurately obtained according to the real contour. By means of the design, whether the pantograph slide plate is abnormal or not does not need to be judged through human experience, the detection accuracy and efficiency are improved, the pantograph slide plate can be monitored in real time in the train running process, alarm prompting can be carried out according to the detection result, and therefore train running safety accidents are effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of train pantograph detection, and in particular relates to a detection method and device for a pantograph sliding plate. Background technique [0002] In recent years, urban rail trains have developed rapidly in my country due to their fast, safe, comfortable and energy-saving features; urban rail trains rely on the pantograph device installed on the top and the catenary arranged along the railway to receive electric energy by sliding contact, and provide Train operation provides basic kinetic energy; however, with the increase of train operating load, the increase of operating mileage and the increase of operating speed, the pantograph is prone to failure defects such as abnormal impact and / or wear; according to statistics, in my country's electrified railway power outages and In serious accidents such as outages, pantograph-catenary accidents account for about 80% of the total accidents; therefore, timely d...
