DEFECT INSPECTION SYSTEM OF OVERHEAD CONTACT LINE

摘要

The present invention relates to a defect inspection system for a traction line and, more particularly, to a defect inspection system for a traction line, which can easily inspect the deformation or damage to facilities on a traction line due to vehicles or external factors by periodically photographing images of ground and underground facilities on the traction line. The defect inspection system for a traction line comprises: a left and right facility detecting device (210) which photographs images of both underground traction line facilities such as an insulator, a rigid steel wire, and a bolt, and ground traction line facilities such as an electric car line, a messenger wire, and a dropper in order to transmit the images to a data collecting and analyzing device (230) in real time; a front and back facility detecting device (220) which photographs images of an operating bracket, that is, a ground traction line facility in order to transmit the images to the data collecting and analyzing device (230) in real time; and the data collecting and analyzing device (230) which collects the front and back images of the operating bracket, that is, a ground traction line facility, detected by the front and back facility detecting device (220) and the images of an electric car line, a messenger wire, a dropper, a rigid steel wire, a bolt, an insulator, and an electric pole, that is, ground traction line facilities, and detects defects by analyzing the collected images with normal images.
