Power transmission line icing monitoring method and system based on image processing mode

Abstract

The invention provides a power transmission line icing monitoring method and system based on an image processing mode. The method comprises the following steps: graying an acquired power transmissionline image; enhancing the power transmission line image; segmenting the power transmission line image according to a threshold segmentation mode to form a preset number of image blocks; presetting anarea threshold of the power transmission line, calculating the area of the power transmission line in each image block, and judging whether the area of the power transmission line in each image blockis greater than the area threshold; when the area of the power transmission line in the image block is greater than an area threshold, extracting the image block; acquiring edge data of the power transmission line in the image block, calculating the distance of the edge of the power transmission line, and judging whether icing exists or not; and if the transmission line is iced, calculating the icing thickness of the transmission line by utilizing an icing thickness algorithm. The system automatically judges the icing state of the power transmission line and gives out early warning and alarm information in time, and various power accidents are effectively prevented.

Description

technical field [0001] The invention relates to the technical field of icing monitoring of power transmission lines, in particular to a method and system for monitoring icing of power transmission lines based on an image processing method. Background technique [0002] Icing on transmission lines often causes accidents such as disconnection and tower collapse. In order to grasp the icing situation of transmission lines, the traditional method is to set up ice-covered observation stations in ice-covered areas, erect simulated conductors, and regularly measure the thickness of ice-covered simulated conductors. Because the observation stations are mostly built in the mountains, the cost is high and the risk is high, and because there are many factors that affect the icing of transmission lines, this method cannot accurately reflect the thickness of ice coating on transmission lines, and the detection results are often very different from the actual ones. [0003] At present, mo...

Since the observation stations are mostly built in the mountains, the cost is high and the risk is high, and because there are many factors affecting the icing of transmission lines, this method cannot accurately reflect the thickness of icing on transmission lines, and the detection results are often very different from the actual ones.

[0003] At present, most of them use manual inspection or unmanned aerial vehicle inspection to check the icing status of transmission lines during the inspection process. However, due to the long distance of transmission lines and the use of various environments, some inspection personnel in the field cannot real-time Check it out

During the flight of the UAV, the acquired inspection images are not clear, which affects the quality of the inspection, and easily leads to misjudgment of the icing status of the transmission line, which in turn affects the stable operation of the entire transmission line.
