An insulator recognition and detection method based on multi-feature information fusion technology

Abstract

The invention discloses a method for identifying and detecting insulators based on multi-feature information fusion technology, which is specifically implemented according to the following steps: Step 1, using a fixed-focus camera with a pan-tilt mounted on an iron tower or an iron pole to collect the insulators on a transmission line Image signal; step 2, preprocessing the image collected in step 1; step 3, extracting the texture feature vector of the insulator from the preprocessed image; step 4, extracting the color feature vector of the insulator to be identified, and collecting the insulator in step 1 The HSV color space of the insulator image is non-equally spaced; Step 5, using the Hu moment algorithm in the region description method to extract the shape features of the insulator; Step 6, extracting the three features of the insulator in Step 3, Step 4, and Step 5 After fusion, the method of the present invention can simply, reliably, quickly and automatically detect the operating state of the insulator, thereby preventing the failure of the power system caused by the breakage of the insulator.

Description

technical field [0001] The invention belongs to the field of online monitoring of power systems, and relates to an insulator identification and detection method based on multi-feature information fusion technology. Background technique [0002] With the proposal of the theoretical concept of the Global Energy Internet, with the UHV grid as the backbone grid and the strong smart grid as the basis, strengthening the real-time monitoring, safety maintenance and operation management of transmission lines is the top priority. In high-voltage transmission lines, poor insulation is the main cause of accidents, and accidents caused by broken insulators currently rank first in the failure rate of power systems. The long-term operation of the insulator outdoors, the interference of various pollutants in the atmosphere and other factors may easily cause internal cracks, surface damage, insulation strength reduction and pollution flashover of the insulator. When there are low-value or ...

AI Technical Summary

Problems solved by technology

The traditional method of checking the operation status of insulators is regular power outages or live manual inspections. These operations not only require boarding poles to inspect pieces one by one, but also high-altitude operations are greatly affected by the environment, high risk, and low work efficiency.
