Insulator real-time target recognizing and tracking device based on motion background

Abstract

The invention relates to an insulator monitoring device used in a power system, in particular to an insulator real-time target recognizing and tracking device based on motion background. The device comprises flying machinery equipment, a ground control system and a communication module, wherein, the flying machinery equipment comprises a flying system and control processing equipment, and the control processing equipment is arranged on the flying system and comprises an imaging detection component and an image signal processing component. The insulator real-time target recognizing and tracking device has the advantages that an image detected by a target insulator is processed on the flying machinery equipment so that insulator detection based on motion analysis is only carried out in a small area in a video window, thus greatly reducing communication transmission time and accelerating the arithmetic operating speed; and in addition, the search range of the target insulator is reduced by means of accurate tracking so that insulator detection and human tracking are almost carried out synchronously, thus achieving the purpose of accurately tracking the insulator and ensuring the detection accuracy and precision of the insulator.

Problems solved by technology

When there are low-value or zero-value insulators in the insulator string, flashover accidents are prone to occur in polluted environments, overvoltages, and even working voltages. When the zero-value insulators are completely broken down, it will cause the insulators to explode, causing transmission lines Hazard of major accident

[0003] At present, the method of measuring zero-value insulators is regular power failure or live manual inspection. These operations need to be inspected piece by piece by climbing a pole. They belong to high-altitude operations, which are greatly affected by the environment, high in danger, and high in labor intensity.

If the zero-value insulator is measured on the ground, the accuracy is not high enough, and it is difficult to judge which insulator has a problem. Aiming at this problem, the scientific research team of this invention project invented a flying robot for detecting transmission line insulators. The patent application number is 200810224172.1 , which solves the problem of detecting insulators by climbing poles, and can greatly reduce labor intensity, which is of great significance

[0004] However, the unresolved technical problem of this technology is that the image detection and recognition of the flying robot are installed on the flight equipment and the ground station respectively. After the target insulator is recognized, it is difficult to complete the tracking of the target insulator because it is always in the moving background. The search range is large, the communication operation time is long, the algorithm operation speed is limited, and it cannot be synchronized with the human body tracking, so it is difficult to ensure sufficient accuracy and precision for the detection of target insulators
