Description

Technical Field

[0001] The invention relates to the field of power facility management, and in particular to an insulator deformation analysis system based on charge detection. Background Art

[0002] In the power supply network, insulators are devices installed between conductors of different potentials or between conductors and grounded components, which can withstand voltage and mechanical stress. There are many types of insulators with different shapes. Although the structures and appearances of different types of insulators are quite different, they are all composed of two major parts: insulating parts and connecting fittings. Insulators are a special type of insulating control that can play an important role in the power supply network. In the early years, insulators were mostly used on electric poles, and gradually developed into a high-type high-voltage electric wire connection tower with many disc-shaped insulators hung on one end. It is to increase the creepage distance. It is usually made of glass or ceramic, which is called an insulator.

[0003] However, insulators are prone to shape deformation under long-term use and in complex external environments. If the shape of the insulator is excessively deformed, it will affect the normal working performance of the insulator and further affect the overall performance of the power supply network where the insulator is located. However, there is currently a lack of effective analysis mechanisms for the deformation level of insulators. Summary of the invention

[0004] In order to solve the technical problems in the related fields, the present invention provides an insulator deformation analysis system based on charge detection, which obtains the pixel value gradients corresponding to each edge pixel point of the image block occupied by the insulator in the received continuous filtered image, and obtains the binary value sequence corresponding to the reference contour graphic corresponding to the insulator. Based on the pixel value gradients corresponding to each edge pixel point of the image block occupied by the insulator in the received continuous filtered image, the total number of each edge pixel point corresponding to the insulator, and the binary value sequence corresponding to the reference contour graphic corresponding to the insulator, an AI analysis model is used to intelligently judge the deformation value representing the deformation level of the insulator, wherein the AI ​​analysis model used for intelligent judgment is a Hoffet neural network after multiple learning of a set total number, and the fewer the edge pixel points of the image block occupied by the insulator in the received continuous filtered image, the smaller the set total number, thereby completing the customized design of the neural network and realizing the intelligent judgment of the deformation level of the insulator appearance.

[0005] According to the present invention, there is provided an insulator deformation analysis system based on charge detection, the system comprising:

[0006] The charge detection mechanism is connected to the power supply network and is used to send a lightning strike determination signal when it is detected that the charge value generated by the power supply network is greater than or equal to a set charge threshold, and is also used to send a lightning strike non-determination signal when it is detected that the charge value generated by the power supply network is less than the set charge threshold;

[0007] A directional video recording mechanism, connected to the charge detection mechanism, for performing a video recording operation facing the insulator closest to the power supply network upon receiving the lightning strike judgment signal, so as to obtain a video frame corresponding to a current timestamp;

[0008] A point image restoration device, connected to the directional video recording mechanism, is used to perform single or multiple point image restoration processing on the received video frame corresponding to the current timestamp, so as to obtain and output a corresponding signal restoration image;

[0009] A real-time enhancement device, connected to the point image restoration device, for performing image frequency domain enhancement processing on the received signal restoration image to obtain and output a corresponding real-time enhanced image;

[0010] A filtering operation device, connected to the real-time enhancement device, for performing a pulse interference removal operation and a Gaussian white noise removal operation on the received real-time enhanced image to obtain and output a corresponding continuous filtered image;

[0011] a gradient processing device connected to the filtering operation device, used to obtain the pixel value gradients corresponding to the edge pixel points of the image blocks occupied by the insulator in the received continuous filtering image, and to obtain the binary value sequence corresponding to the reference contour graphic corresponding to the insulator, and to use an AI analysis model to intelligently determine the deformation value representing the deformation level of the insulator based on the pixel value gradients corresponding to the edge pixel points of the image blocks occupied by the insulator in the received continuous filtering image, the total number of edge pixel points corresponding to the insulator, and the binary value sequence corresponding to the reference contour graphic corresponding to the insulator, wherein the AI ​​analysis model is a Hoffet neural network after multiple learning of a set total number, and the fewer the edge pixel points of the image blocks occupied by the insulator in the received continuous filtering image, the smaller the set total number;

[0012] a request triggering device connected to the gradient processing device, and configured to send an insulator replacement request including a corresponding number of the insulator to a remote line management server via a wireless communication link when a received deformation value indicating a deformation level of the insulator is greater than or equal to a set level threshold;

[0013] The request trigger device is also used to stop sending the insulator replacement request including the corresponding number of the insulator to the remote line management server through the wireless communication link when the received deformation value representing the deformation level of the insulator is less than the set level threshold.

[0014] It can be seen that the present invention has at least the following three significant substantive features:

[0015] Substantive feature 1: Obtain the pixel value gradients corresponding to the edge pixel points of the image blocks occupied by the insulator in the received continuous filtered image, and obtain the binary value sequence corresponding to the reference contour graphic corresponding to the insulator. Based on the pixel value gradients corresponding to the edge pixel points of the image blocks occupied by the insulator in the received continuous filtered image, the total number of edge pixel points corresponding to the insulator, and the binary value sequence corresponding to the reference contour graphic corresponding to the insulator, an AI analysis model is used to intelligently determine the deformation value representing the deformation level of the insulator;

[0016] Substantive feature 2: The AI ​​analysis model used for intelligent judgment is a Hoffet neural network that has undergone a set number of multiple learnings, and the fewer edge pixels of each image block occupied by the insulator in the received continuous filtered image, the smaller the set number, thereby completing the customized design of the neural network;

[0017] Substantive feature three: Only when it is detected that the charge value generated by the power supply grid is greater than or equal to the set charge threshold, a lightning strike judgment signal is issued to trigger the recording operation performed on the insulator closest to the power supply grid, thereby reducing the power consumption of the entire monitoring system. When the deformation value representing the deformation level of the insulator obtained after intelligent analysis is greater than or equal to the set level threshold, an insulator replacement request including the corresponding number of the insulator is sent to the remote line management server through the wireless communication link, thereby completing the intelligent analysis of the deformation state of the insulator most recently after the lightning strike on the power supply grid and the automatic triggering of the insulator replacement request, thereby improving the intelligence and automation levels of overhead line management.

[0018] The insulator deformation analysis system based on charge detection of the present invention is compact in design and widely used. By acquiring various targeted visual data of the insulator and using a customized AI analysis model to intelligently determine the deformation value representing the deformation level of the insulator, the intelligent determination of the deformation level of the insulator shape is achieved.
