Description

Technical Field

[0001] The present invention relates to the field of power transmission lines, and more specifically, to an ice prism detection system on a power transmission line. Background Art

[0002] Transmission lines are composed of line towers, conductors, insulators, line fittings, guy wires, tower foundations, grounding devices, etc., and are erected on the ground. According to the nature of the transmitted current, power transmission is divided into AC transmission and DC transmission. DC transmission was first successfully realized. However, since the voltage of DC transmission was difficult to continue to increase under the technical conditions at the time, the transmission capacity and benefits were limited, so DC transmission was gradually replaced by AC transmission.

[0003] Transmission lines are widely used in complex and changeable outdoor environments. The prior art CN117371227A discloses an online prediction method, device and storage medium for transmission towers. The online prediction device is arranged on two transmission towers themselves and on the conductors and ground wires between them. The ambient temperature, ice thickness, wind speed direction, conductor tension and ground wire tension are obtained through a variety of sensors to obtain the ground wire line hanging point load and the tower body wind load and import them into the transmission tower three-dimensional simulation model for force calculation, and obtain the stress calculation value and deformation calculation value of the key parts of the transmission tower. Based on the measured deformation data of the top of the transmission tower and the measured stress data of the key parts of the tower body, the calculated values ​​are compared and analyzed, the stress state of the transmission tower is evaluated, and the hidden danger points of the key parts of the transmission tower structure are predicted in real time; the invention can digitally process and accurately calculate the influence of meteorology and environment on the transmission tower itself and the ground wire between them, and discover and predict the possible problems and hidden dangers of the tower.

[0004] Obviously, transmission lines need to withstand the test of complex and changeable outdoor environments, especially under the set meteorological conditions of high humidity and low temperature. Ice prisms of different sizes and volumes formed on the transmission lines will have varying degrees of impact on the operational safety of the transmission lines. Summary of the invention

[0005] In order to solve the technical problems in the related fields, the present invention provides an ice prism detection system on a transmission line. The system can be used to complete the intelligent identification processing of the current length value corresponding to the ice prism by using an AI identification body by introducing a targetedly designed data operation device including a network training device, a multi-parameter analysis device and a length identification device. Specifically, the deep neural network is trained multiple times to obtain the corresponding AI identification body, and the horizontal coordinate value and vertical coordinate value of each pixel point of the ice prism in the received gradient filtered image, the overall depth of field value of the ice prism in the gradient filtered image and the total number of pixels occupied by the ice prism in the gradient filtered image are input into the AI ​​identification body in parallel to run the AI ​​identification body to obtain the current length value corresponding to the ice prism output by the AI ​​identification body, thereby providing key data for the detection of excessively long ice prisms.
