Description

Technical Field

[0001] The present invention relates to the field of electric power facilities, and in particular to an insulator management system for electric power equipment. Background Art

[0002] The main functions of insulators are to achieve electrical insulation and mechanical fixation, for which various electrical and mechanical performance requirements are specified.

[0003] For example, under the specified operating voltage, lightning overvoltage and internal overvoltage, no breakdown or surface flashover occurs; under the specified long-term and short-term mechanical load, no destruction or damage occurs; after long-term operation under the specified mechanical and electrical loads and various environmental conditions, no obvious degradation occurs; the hardware of the insulator does not produce obvious corona discharge under the operating voltage to avoid interfering with radio or television reception. Because insulators are widely used devices, their connecting hardware is also required to be interchangeable.

[0004] In addition, the technical standards for insulators also require that insulators be subjected to various electrical, mechanical, physical and environmental condition tests depending on the model and conditions of use to verify their performance and quality.

[0005] In the prior art, the environment in which power facilities are located is relatively complex. For example, trees near insulators are constantly growing, and the position of insulators may also change during long-term use. If insulators are too close to trees, it will cause great hidden dangers to the safety and stability of the entire power facility where the insulators are located. Summary of the invention

[0006] In order to solve the technical problems in the related field, the present invention provides an insulator management system for power equipment, the system comprising: A flight control mechanism is provided in the flight patrol device, and is used to drive the flight patrol device to perform hovering operations of the same set duration at various locations along the overhead line based on the navigation data of various locations along the overhead line received wirelessly; an aerial photography execution mechanism connected to the flight control mechanism, and configured to complete an aerial photography action on the bottom of the flight patrol device each time the flight control mechanism drives the flight patrol device to perform a hovering operation of a set duration, so as to obtain and output a corresponding on-site aerial photography image; A customized filtering device, which is arranged in the flight inspection device and connected to the aerial photography actuator, is used to perform maximum filtering processing on the received image to obtain and output a corresponding maximum filtering image; A data sharpening device, connected to the custom filtering device, for performing a spatial differential sharpening process on the received maximum value filtered image to obtain and output a corresponding data sharpened image; a content enhancement device, connected to the data sharpening device, for performing image content enhancement processing based on logarithmic transformation on the received data sharpened image, so as to obtain and output a corresponding content enhanced image; A scene detection mechanism, which is arranged in the flying inspection device and connected to the content enhancement device, is used to detect the image block occupied by the insulator in the content enhancement image based on the brightness value range corresponding to the insulator, and obtain the depth of field values ​​corresponding to the pixel points of the image block occupied by the insulator, build a stereoscopic vision model corresponding to the insulator based on the coordinate values ​​corresponding to the pixel points of the image block occupied by the insulator and the depth of field values ​​corresponding to the pixel points of the image block occupied by the insulator, and estimate the volume estimation value corresponding to the insulator based on the stereoscopic vision model and the imaging focal length of the imaging lens, and the scene identification device is used to determine whether the image block occupied by the insulator overlaps with the image block occupied by trees near the image block occupied by the insulator when the volume estimation value corresponding to the insulator does not match the physical volume value corresponding to the insulator, and send a tree occlusion detection signal when there is an overlap, and send other object occlusion detection signal when there is no overlap; The abnormality reporting mechanism is connected to the scene detection mechanism and is used for wirelessly transmitting the received tree occlusion detection signal or other object occlusion detection signal to a remote overhead line maintenance server.

[0007] The insulator management system for electric power equipment of the present invention has a compact structure and intelligent control. Since a targeted visual analysis mechanism can be used to determine the stereoscopic visual model corresponding to the insulator, and the volume estimation value corresponding to the insulator is estimated based on the stereoscopic visual model and the imaging focal length of the imaging lens, reference information is provided for whether the insulator is blocked.
