Abstract

The invention discloses a pantograph sliding plate detection method and device. The invention can obtain the image of the pantograph sliding plate in real time, and based on image recognition, recognize the upper and lower edges of the pantograph sliding plate in the image, thereby obtaining the pantograph sliding plate. The real outline of the pantograph slide, thus, the abnormal wear of the pantograph slide can be accurately obtained according to the real outline; through the above design, the present invention does not need to use human experience to judge whether there is an abnormality in the pantograph slide, which not only improves The accuracy and efficiency of the detection can also be monitored in real time on the pantograph sliding plate during the operation of the train, so that an alarm can be given according to the detection results, so as to effectively prevent the occurrence of train driving safety accidents.

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...
