Description

Technical Field

[0001] The present invention relates to the field of power transmission networks, and more specifically, to a power transmission network insulator string safety identification system. Background Art

[0002] The stress conditions of the tension insulator string are completely different from those of the suspension insulator string. Under normal operation, the suspension insulator string only bears vertical loads and does not bear the conductor tension, while the tension insulator string is just the opposite. It mainly bears the entire horizontal tension of the conductor. Like the suspension insulator string, after the number of insulators required for each string is determined, the method of hanging the wire points should be selected. Because the hanging point is where the force of the insulator string is more concentrated, we should choose a hanging method with a simple structure, flexible rotation, convenient construction, and clear force. Because of this, although there are many hanging methods for overhead transmission lines, the main one-point hanging method and two-point hanging method are usually used. Since these two hanging methods can be rotated freely up and down and left and right, this hanging structure is suitable for both the change of the turning angle and the need for the downward inclination of the conductor.

[0003] CN119448059A discloses a device for removing pins from a ground potential replacement insulator string, comprising: a main frame, a roller, a rack, an M-type pin removal head and an R-type pin removal head; the roller is rotatably arranged in the main frame; the rack is movably arranged in the main frame and meshed with the roller; the M-type pin removal head is fixed at one end of the rack; the R-type pin removal head is fixed at the other end of the rack. This technology solves the problem that it is difficult for traditional tools to complete the removal of R-type pins, as the M-type pin removal head and the R-type pin removal head are installed at the left and right ends of the rack, respectively. The innovatively developed pin removal device can realize the simple and fast removal of R-type pins. At the same time, the M-type pin removal head uses a forward push pin tail method to complete the pin removal, and the R-type pin removal head uses a reverse pull pin head method to complete the pin removal, so that the two operations share a torsion transmission stroke and a set of in-place locking holes, simplifying the tools while reducing their own counterweight.

[0004] CN119419638A discloses an auxiliary replacement device and method for a suspended double insulator string, which simplifies the auxiliary replacement process of the suspended double insulator string, and effectively simplifies the replacement process of the suspended double insulator string by cooperating with a load-bearing plate and a hoist. The invention can keep the second connecting plate in a horizontal state during the replacement operation, and achieves stable support for the second connecting plate by introducing a structural design of a load-bearing plate and a positioning pin in the device; a pulling force is applied by the hoist to transfer the bearing pulling force of the two insulators to the hoist; and the hoist is located on the center line to avoid the problem of uneven force caused by the "carrying the load" phenomenon, and avoids the unbalanced force on the insulator string at the untied end due to the tilting of the second connecting plate, and the insulator string on the other side tilts downward due to the influence of gravity, resulting in the inability to smoothly remove the cross arm hanging point bolts at the untied end.

[0005] CN119269983A discloses an insulator string zero-value diagnosis method and system. The method includes: analyzing insulator strings of different types to determine the voltage distribution of insulators at each position of the insulator string under normal operating conditions and under the condition of zero-value insulators; determining the position of sensitive insulators according to the determined voltage distribution; determining the light-emitting threshold of the electroluminescent material according to the voltage distribution value at the position of the sensitive insulator; selecting the electroluminescent material according to the light-emitting threshold, and using the electroluminescent material to emit light according to the voltage change of the sensitive insulator, and determining whether the insulator string to be diagnosed has a zero-value fault according to the light-emitting state. This technology realizes the single-piece or double-piece insulator alarm function when the insulator string has a zero-value fault by finding the position of the sensitive insulator in the transmission line insulator string and combining the application of the electroluminescent material. Summary of the Invention

[0006] To solve the technical problems in related fields, the present invention provides a safety appraisal system for transmission network insulator strings. By introducing a multiple enhancement mechanism with a targeted structural design to perform gamma correction, piecewise linear gray-scale transformation, and image smoothing using maximum filtering on the received tower environment image sequence, a multiple enhanced image with better image quality is obtained and output, providing reliable basic data for subsequent visual distance measurement. It also obtains the image block of the operating electrician in the multiple enhanced image as the image block occupied by the operating electrician, and obtains the image block of the insulator string in the multiple enhanced image as the image block occupied by the insulator string. It obtains each edge pixel point of the image block occupied by the operating electrician and each edge pixel point of the image block occupied by the insulator string, and determines the on-site distance between the operating electrician and the insulator string based on the horizontal coordinate values and vertical coordinate values of each edge pixel point of the image block occupied by the operating electrician and the horizontal coordinate values and vertical coordinate values of each edge pixel point of the image block occupied by the insulator string. Among them, the on-site distance between the operating electrician and the insulator string is determined based on the horizontal coordinate value, vertical coordinate value of a single edge pixel point of the image block occupied by the operating electrician with the shortest distance and the horizontal coordinate value, vertical coordinate value of a single edge pixel point of the image block occupied by the insulator string. The larger the shortest distance value is, the smaller the determined on-site distance between the operating electrician and the insulator string is.

Among them, the on-site distance between the operating electrician and the insulator string is determined based on the horizontal coordinate values and vertical coordinate values of a single edge pixel point of the image block occupied by the operating electrician with the shortest distance and the horizontal coordinate values and vertical coordinate values of a single edge pixel point of the image block occupied by the insulator string.

The larger the shortest distance value is, the smaller the determined on-site distance between the operating electrician and the insulator string is; An on-site identification component is connected to the touch judgment component, and is used to send out a touch warning signal that the operating electrician on the target tower is close to touching the insulator string when the on-site distance between the received operating electrician and the insulator string is close to zero; Among them, the on-site identification component is connected to the touch judgment component, and is used to send out a touch warning signal that the operating electrician on the target tower is close to touching the insulator string when the on-site distance between the received operating electrician and the insulator string is close to zero, including: when the value of the on-site distance between the received operating electrician and the insulator string is between zero and the set distance threshold, it is judged that the on-site distance between the received operating electrician and the insulator string is close to zero.

Since a multiple enhancement mechanism with a targeted structural design can be introduced to perform image quality optimization processing on the received tower environment images in sequence, and the on-site distance between the operating electrician and the insulator string is determined based on various visual information in the optimized images, the management level of the transmission network is improved.
