Description

Technical Field

[0001] The invention relates to the field of electric power equipment, and in particular to an insulator for a power transmission line. Background Art

[0002] Power lines mainly include overhead lines and cable lines, and their structural forms are different. Since overhead lines have many advantages over cable lines, such as low cost and low investment, easy installation, convenient maintenance and repair, easy to find and troubleshoot faults, etc., overhead lines are widely used in general factories. However, overhead lines are directly affected by the atmosphere, vulnerable to lightning strikes and polluted air hazards, and overhead lines occupy a certain amount of ground and space, which hinders traffic and appearance. Therefore, they are subject to certain restrictions. Modern factories tend to gradually reduce overhead lines and use cable lines instead. Compared with overhead lines, cable lines have the disadvantages of high cost, large investment, and inconvenient maintenance, but they have the advantages of reliable operation, not easily affected by the outside world, no need to set up poles, no ground occupation, and no obstruction of appearance. Especially in places with corrosive gases and flammable and explosive places, when it is not suitable to set up overhead lines, only cable lines can be laid.

[0003] There are many potential safety hazards in the operation of power lines that need to be checked and eliminated. The monitoring schemes of power lines in the existing technology cannot exhaust the mechanisms for checking and eliminating these potential safety hazards. For example, it is impossible to determine with high precision whether there are sand holes in the iron parts of each power line being monitored, resulting in the inability to make detailed identification of the working performance of each iron part of the power line. Summary of the invention

[0004] In order to solve the technical problems in the related fields, the present invention provides a transmission line insulator, which can issue a target identification instruction corresponding to confirming the presence of sand holes in the iron parts when there are two different types of depth of field values ​​with the same value between each first type depth of field value and each second type depth of field value and there is an overlapping area between the imaging area occupied by the iron parts in the received sequential enhanced image and the imaging area occupied by the sand holes in the received sequential enhanced image; and issue a target non-identification instruction corresponding to confirming the absence of sand holes in the iron parts when there are not two different types of depth of field values ​​with the same value between each first type depth of field value and each second type depth of field value or there is no overlapping area between the imaging area occupied by the iron parts in the received sequential enhanced image and the imaging area occupied by the sand holes in the received sequential enhanced image, thereby realizing intelligent existence identification of sand holes on the iron parts maintaining the insulators.

[0005] According to the present invention, there is provided a transmission line insulator, comprising a transmission line insulator body and an image analysis system for surface identification of the insulator body, the system comprising: A time-controlled acquisition component is arranged opposite to the iron piece attached to the main body of the transmission line insulator, and is used to use a macro lens to execute the acquisition picture corresponding to each acquisition moment executed on the surface of the iron piece based on an uneven time-sharing acquisition mode and output it as a current acquisition frame. In the uneven time-sharing acquisition mode, the frequency of executing acquisition is faster in the time segment farther away from the installation moment of the iron piece; A sequential enhancement component, connected to the time-controlled acquisition component, for sequentially performing pulse interference removal operation, histogram equalization operation, horizontal sharpening operation and vertical sharpening operation on the received current acquisition frame to obtain and output a corresponding sequentially enhanced image; A head-end analysis mechanism, connected to the sequential enhancement component, is used to obtain the depth of field values ​​corresponding to the respective pixel points of the imaging area occupied by the iron piece in the received sequential enhancement image as the first type of depth of field values, and to obtain the depth of field values ​​corresponding to the respective pixel points of the imaging area occupied by the sand hole in the received sequential enhancement image as the second type of depth of field values; The secondary end analysis mechanism is connected to the primary end analysis mechanism and is used to issue a target identification instruction corresponding to confirming that there are sand holes in the iron piece when there are two different types of depth of field values ​​with the same value among each first type of depth of field value and each second type of depth of field value and there is an overlapping area between the imaging area occupied by the iron piece in the received sequential enhanced image and the imaging area occupied by the sand hole in the received sequential enhanced image; The secondary end analysis mechanism is further used to issue a target unidentified instruction to confirm that there are no sand holes in the iron piece when there are no two different types of depth of field values ​​with the same value in each first type of depth of field value and each second type of depth of field value or there is no overlapping area between the imaging area occupied by the iron piece in the received sequential enhanced image and the imaging area occupied by the sand hole in the received sequential enhanced image; Among them, the sequential enhancement component is connected to the time-controlled acquisition component, and is used to sequentially perform pulse interference removal operation, histogram equalization operation, horizontal sharpening operation and vertical sharpening operation on the received current acquisition frame to obtain and output the corresponding sequential enhanced image, including: the sequential enhancement component includes multiple enhancement processing components, which are used to respectively perform pulse interference removal operation, histogram equalization operation, horizontal sharpening operation and vertical sharpening operation.

[0006] Therefore, the present invention has at least the following three beneficial technical effects: Firstly: obtaining the depth of field values ​​respectively corresponding to the constituent pixel points of the imaging area occupied by the iron piece in the received sequential enhanced image as the first type of depth of field values, and obtaining the depth of field values ​​respectively corresponding to the constituent pixel points of the imaging area occupied by the sand hole in the received sequential enhanced image as the second type of depth of field values, so as to provide key data for subsequent state recognition; Secondly: when there are two different types of depth of field values ​​with the same value between each first type of depth of field value and each second type of depth of field value, and there is an overlapping area between the imaging area occupied by the iron piece in the received sequential enhanced image and the imaging area occupied by the sand hole in the received sequential enhanced image, a target identification instruction corresponding to confirming the existence of sand holes in the iron piece is issued; and when there are not two different types of depth of field values ​​with the same value between each first type of depth of field value and each second type of depth of field value, or there is no overlapping area between the imaging area occupied by the iron piece in the received sequential enhanced image and the imaging area occupied by the sand hole in the received sequential enhanced image, a target non-identification instruction corresponding to confirming the absence of sand holes in the iron piece is issued, thereby realizing intelligent existence identification of sand holes on the iron pieces that maintain insulators; Again: a targeted image content enhancement mechanism including pulse interference removal operation, histogram equalization operation, horizontal sharpening operation and vertical sharpening operation is used to improve the picture quality of the ironwork imaging image to obtain a corresponding sequential enhanced image.

[0007] The power transmission line insulator of the present invention has compact logic and stable operation. When each first type depth of field value and each second type depth of field value have two different types of depth of field values ​​with the same value and the imaging area occupied by the iron piece and the imaging area occupied by the sand hole have overlapping areas, a target identification instruction corresponding to confirming the existence of the sand hole in the iron piece is issued, thereby realizing intelligent existence identification of the sand hole on the iron piece maintaining the insulator.
