Electric pole and tower maintenance and pre-warning system based on panoramas

Abstract

The invention relates to an electric pole and tower maintenance and pre-warning system based on panoramas and belongs to the field of equipment monitoring. The system is characterized in that image processing registering is used, the panoramas of the same electric pole and tower at different time periods are analyzed to extract features and obtain feature points; digital image processing Sobel operator and Canny operator extraction are used to extract the peripheral contour of the electric pole and tower, and set union is performed on the boundary contours extracted by two operators to obtain the contour point sets of the pole and tower; similarity measurement is performed on the contour point sets of two images to find out matched feature point pairs; the displacement difference relation of each feature point pair is analyzed to obtain image space coordinate change parameters and determine areas with large point pair change; the changed areas can be obtained after registering, whether harm occurs or not can be judged by the proportion of the changed areas to the panoramas, and a pre-warning message is given out if the proportion exceeds a preset proportion. By the system widely applicable to electric pole and tower maintenance and pre-warning, electric pole and tower fault rate can be further lowered.

Description

technical field [0001] The invention belongs to the field of equipment monitoring, and in particular relates to a system for monitoring and early warning of the stability and safety status of the metal member structure of a high-voltage transmission line power pole and tower. Background technique [0002] In recent years, with the development of society and economy, new problems have emerged in the maintenance of power poles and towers. [0003] In the Shanghai area, there are currently more than 4,000 kilometers of 220kV and above transmission lines and thousands of towers. It is very important to maintain and collect information on the status of these power towers, and it is of great significance to ensure the safe operation of the power grid and provide decision-making basis. [0004] The maintenance of traditional power poles and towers only has a simple data system, which describes various information of power poles and towers such as location, operation status, mainte...

Problems solved by technology

[0004] The maintenance of traditional power poles and towers only has a simple data system, which describes various information of power poles and towers such as location, operation status, maintenance records, etc. Traditional records are only text information, and all power poles and towers cannot be fully seen on the map It is impossible to see the overall information comprehensively. Some systems plus GIS information can only find the corresponding power tower location information from the map. It is also only text information and cannot get the intuitive status information of the power tower.

At present, there are digital image information of power towers added to it, and the corresponding digital images of power towers can be viewed according to the GIS information, but the information obtained by this kind of viewing is one-sided and incomplete, and it is difficult to understand continuously, intuitively and three-dimensionally Information to power towers
