Description

Technical Field

[0001] The present invention relates to the field of electric power facilities, and in particular to an intelligent management system for insulators on transmission lines. Background Art

[0002] Transmission facilities are one of the main types of power facilities. Transmission facilities refer to the facilities that transmit electricity from power plants to the power grid, mainly including transmission lines and substations. Transmission lines are generally divided into three types: high voltage, medium voltage and low voltage. High voltage lines are mainly used for long-distance and large-capacity transmission, while medium voltage and low voltage lines are used for power distribution in cities and villages respectively. Substations are facilities that connect high voltage, medium voltage and low voltage lines. Their main function is to transform voltage and regulate power transmission and distribution.

[0003] Insulators are a type of transmission facility that is widely used. The physical shape of insulators is standard when they leave the factory. However, insulators may have problems after long-term use in the field, which may affect their working performance. However, if insulators are managed manually, there will be great inconveniences because they are on the transmission line. Summary of the invention

[0004] In order to solve the technical problems in the prior art, the present invention provides an intelligent management system for insulators on transmission lines, which can identify the occupation pattern of the target insulator in the sequence enhancement picture based on the color imaging characteristics corresponding to the target insulator, obtain the vertical coordinate data and horizontal coordinate data of each edge pixel point of the occupation pattern corresponding to the target insulator, and intelligently analyze the entity deformation level corresponding to the target insulator according to the vertical coordinate data and horizontal coordinate data of each edge pixel point of the occupation pattern corresponding to the target insulator, the total number of each edge pixel point and the reference bird's-eye view contour pattern corresponding to the target insulator, thereby completing non-contact and high-precision shape analysis of the target insulator entity.

[0005] According to the present invention, an intelligent management system for insulators on a transmission line is provided, the system comprising: A bird's-eye view camera mechanism is arranged on a transmission line tower where a target insulator is suspended, and is used to perform a camera operation on the scene where the target insulator is located using a bird's-eye view to obtain and output an instant bird's-eye view picture corresponding to the current moment; The order enhancement mechanism is arranged in the base of the transmission line iron tower and is wiredly connected to the bird's-eye view camera mechanism, and includes a first enhancement component, a second enhancement component and a third enhancement component, which sequentially performs image SVD enhancement processing, guided filtering processing and edge-preserving smoothing filtering processing on the received real-time bird's-eye view picture to obtain and output a corresponding order enhancement picture; a coordinate processing mechanism connected to the order enhancement mechanism, configured to receive the order enhancement picture, identify an occupation pattern of the target insulator in the order enhancement picture based on a color imaging characteristic corresponding to the target insulator, the color imaging characteristic corresponding to the target insulator being a numerical distribution interval of each component of the target insulator in an RGB color space, obtain vertical coordinate data and horizontal coordinate data of each edge pixel point of the occupation pattern corresponding to the target insulator, and intelligently analyze the entity deformation level corresponding to the target insulator according to the vertical coordinate data and horizontal coordinate data of each edge pixel point of the occupation pattern corresponding to the target insulator, the total number of each edge pixel point, and a reference bird's-eye view outline pattern corresponding to the target insulator, wherein the intelligent analysis is based on a BP neural network and the reference bird's-eye view outline pattern corresponding to the target insulator and is represented by a binary value; An information forwarding mechanism, connected to the coordinate processing mechanism, is used to send the entity deformation level corresponding to the target insulator of the intelligent analysis and the target insulator deformation excess information to a remote power facility server through a network when the entity deformation level corresponding to the target insulator of the intelligent analysis is greater than or equal to the set level threshold; Among them, the entity deformation level corresponding to the target insulator is intelligently analyzed according to the vertical coordinate data and horizontal coordinate data of each edge pixel point of the occupied pattern corresponding to the target insulator, the total number of each edge pixel point and the reference bird's-eye view outline pattern corresponding to the target insulator. The intelligent analysis is based on the BP neural network and the reference bird's-eye view outline pattern corresponding to the target insulator, which is represented by binary values ​​and includes: the reference bird's-eye view outline pattern corresponding to the target insulator is an imaging pattern of the target insulator taken in a factory state with a bird's-eye view and only includes the target insulator.

[0006] Therefore, the present invention has the following three outstanding technical effects: Firstly, based on the color imaging characteristics corresponding to the target insulator, the occupation pattern of the target insulator in the order enhancement picture is identified. The color imaging characteristics corresponding to the target insulator are the numerical distribution intervals of each component of the target insulator in the RGB color space. The vertical coordinate data and horizontal coordinate data of each edge pixel point of the occupation pattern corresponding to the target insulator are obtained. Secondly: intelligently analyze the entity deformation level of the target insulator according to the vertical coordinate data and horizontal coordinate data of each edge pixel point of the occupied pattern corresponding to the target insulator, the total number of each edge pixel point and the reference bird's-eye view outline pattern corresponding to the target insulator, wherein the intelligent analysis is based on the BP neural network and the reference bird's-eye view outline pattern corresponding to the target insulator is represented by a binary value, thereby completing the non-contact shape analysis of the target insulator entity; Again: when the physical deformation level corresponding to the target insulator of the intelligent analysis is greater than or equal to the set level threshold, the physical deformation level corresponding to the target insulator of the intelligent analysis and the excessive deformation information of the target insulator are sent to the remote power facility server through the network, thereby completing the network transmission of the intelligent analysis data of the deformation degree of each insulator under the use status.

[0007] The intelligent management system for insulators on transmission lines of the present invention is intelligently designed and widely used. Since it can intelligently analyze the entity deformation level corresponding to the target insulator based on various visual data of the target insulator and the reference bird's-eye view outline pattern corresponding to the target insulator, it can complete the non-contact high-precision shape analysis of the target insulator entity to avoid affecting the working performance of the target insulator.
