In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0030] Referring to Figures 1 and 2, a grounding wire device is provided according to a specific embodiment of the present invention.

[0031] Specifically, as shown in Figures 1 and 2, the grounding device includes: a connection part 10, which has a first clamp 11 with an opening on one side for holding a wire; a movable part 20, which is movably connected to the connection part 10, and has an initial position away from the first clamp 11, and a working position that cooperates with the first clamp 11. When the movable part 20 is in the working position, the movable part 20 and the first clamp 11 form a clamping space for holding the wire; and an image processing device 30, which is disposed on the connection part 10 and is used to acquire image information of the wire being clamped by the movable part 20 and the first clamp 11, and to detect the fit between the wire and the connection part 10 and the movable part 20 based on the image information.

[0032] In this embodiment, the grounding wire device can quickly switch between the initial position and the working position through the movable part 20 and the wiring part 10, realizing the rapid clamping and release of the wire. This setting improves the efficiency of grounding wire installation and removal, reduces operation time, and can respond quickly in emergency situations or scenarios requiring frequent operation, thereby improving safety. The image processing device 30 can acquire image information of the movable part 20 and the first clamp 11 clamping the wire, and detect the fit between the wire and the wiring part 10 and the movable part 20 in real time based on image analysis technology. This real-time monitoring function can immediately provide feedback on the installation status of the wire, promptly detect poor fit, avoid safety hazards caused by poor grounding wire contact, and improve the accuracy and timeliness of detection.

[0033] It should be noted that when the movable part 20 is in the working position, the movable part 20 is connected to the first chuck 11, or the movable part 20 abuts against the first chuck 11.

[0034] Furthermore, the wiring part 10 includes: a receiving part 12, which is disposed on the side away from the first chuck 11, and the receiving part 12 has a receiving cavity 121 through which the movable part 20 passes; wherein the movable part 20 is rotatably connected to the receiving part 12, and the movable part 20 is operated to rotate so that the movable part 20 switches between an initial position and a working position.

[0035] Specifically, the movable part 20 is rotatably connected to the receiving part 12, allowing the movable part 20 to freely switch between an initial position and a working position. This design increases the flexibility of the device, enabling the operator to flexibly adjust the angle of the movable part 20 according to the specific position and direction of the wire to achieve the best clamping effect.

[0036] Furthermore, the movable part 20 includes: a movable rod 21, which is movably disposed within the receiving cavity 121; a second clamp 22, which is movably connected to one end of the movable rod 21; and an elastic member 23, which is disposed circumferentially along the movable rod 21, with one end of the elastic member 23 abutting against the second clamp 22 and the other end of the elastic member 23 abutting against the outer wall of the receiving part 12.

[0037] Specifically, when the movable rod 21 is in the initial position, the elastic element 23 is in the compressed state; when the movable rod 21 is in the working position, the elastic element 23 is in the released state. The setting of the elastic element 23 can realize the automatic reset of the movable rod 21 without external force. When the operator rotates to release the movable rod 21, the elastic element 23 can push it back to the locking state that cooperates with the first clamp 11, ensuring that the wire is firmly clamped.

[0038] Meanwhile, the second clamp 22 is movably connected to one end of the movable rod 21, so that when the operator rotates the movable rod 21, the movable rod 21 will not drive the second clamp 22 to rotate. The second clamp 22 always maintains the position and posture that cooperates with the first clamp 11, ensuring the reliability of clamping the wire.

[0039] In this embodiment, the elastic element 23 is a compression spring; in other embodiments, the type of elastic element 23 is not limited to this.

[0040] Further, the receiving part 12 includes: a bottom shell 122, one end of which is provided with a first clamp 11; a frame 123, which is disposed on the bottom shell 122 and is disposed at a distance from the first clamp 11. The frame 123 is provided with at least two threaded grooves 1231, which are spaced apart in the horizontal direction and are connected to the receiving cavity 121. An elastic member 23 is disposed between the second clamp 22 and the frame 123, one end of which abuts against the second clamp 22 and the other end of which abuts against the outer wall of the frame 123.

[0041] Furthermore, the movable rod 21 is provided with a threaded protrusion 211. When the movable rod 21 is in the initial position, the threaded protrusion 211 is located in the threaded groove 1231 away from the first chuck 11. When the movable rod 21 is in the working position, the threaded protrusion 211 is located in the threaded groove 1231 close to the first chuck 11.

[0042] By setting a precise fit between the threaded protrusion 211 and the threaded groove 1231, the device can stably adjust the distance between the second chuck 22 and the first chuck 11 during the process of the movable rod 21 moving from the initial position to the working position, ensuring precise control of the contact pressure, thereby improving the stability and reliability of the grounding wire connection.

[0043] Furthermore, the movable part 20 also includes: an insulating rod 24, one end of which is movably connected to the movable rod 21, and the other end of which is provided with a take-up reel 26; a locking member 25, which has a locking groove, is disposed on one side of the take-up reel 26, and has a locking state that locks the wire into the locking groove, and an unlocking state that unlocks the wire.

[0044] Specifically, during use, the elastic element 23 is controlled in a compressed state, and then the grounding wire device is uploaded to the tower. The tail is hung on the tower by the locking element 25 to prevent it from falling. The camera unit 31 is opened, and the wire is hooked by the first clamp 11. The insulating rod 24 is rotated, and after the tail thread is separated, the elastic element 23 will move forward quickly, tightening the threaded protrusion 211 of the movable rod 21 with the threaded groove 1231 near the first clamp 11. After tightening, the camera unit 31 can take pictures in real time or control the taking of pictures.

[0045] Furthermore, the second clamp 22 is provided with a connecting block 221 on the side facing the movable rod 21, and the movable rod 21 is movably connected to the connecting block 221.

[0046] Specifically, the connecting block 221 causes the movable rod 21 to rotate, while the second chuck 22 moves linearly to maintain reliable contact with the first chuck 11.

[0047] Furthermore, the image processing device 30 includes: a camera unit 31, which is disposed on at least one side of the bottom shell 122 near the first clamp 11, and is used to acquire image information of the first clamp 11 and the second clamp 22 clamping the wire; and a data processing unit 32, which is communicatively connected to the camera unit 31, and is used to determine the fit between the first clamp 11, the second clamp 22 and the wire based on the image information.

[0048] As shown in Figure 3, according to another aspect of the present invention, a method for real-time identification of grounding wire fit is provided, which employs the grounding wire device of the above embodiment, and the method includes:

[0049] Step S10: Obtain image information of the grounding device clamping the conductor.

[0050] In the technical solution provided by step S10 of the present invention, the image information includes edge information and contour information of the contact area between the grounding device and the conductor. The edge information includes the first edge information of the contact area between the first clamp and the conductor and the second edge information of the contact area between the second clamp and the conductor. The contour information includes the first contour information of the contact area between the first clamp and the conductor and the second contour information of the contact area between the second clamp and the conductor.

[0051] In this embodiment, the camera unit 31 can capture images in real time or periodically. After obtaining the image information of the grounding device clamping the wire in step S10, the image information is transmitted to the data processing unit 32. The data processing unit 32 judges the fit between the first clamp 11, the second clamp 22 and the wire based on the image information.

[0052] Step S12: Preprocess the image information to obtain the target image information.

[0053] In the technical solution provided by step S12 of the present invention, the preprocessing includes grayscale processing and noise reduction processing.

[0054] The image information mentioned above is initially a color image, which is then preprocessed to be converted into a grayscale image, and grayscale values ​​are obtained based on the grayscale image.

[0055] Specifically, the weighted average method is used, and the calculation formula is: Gray = 0.299R + 0.587G = 0.114B (1)

[0056] Where Gray represents the grayscale value, and R, G, and B are the values ​​of the red, green, and blue channels in the color image, respectively. This reduces the amount of data required for subsequent processing while highlighting the image's texture and edge information.

[0057] The above-mentioned denoising process uses methods such as median filtering or Gaussian filtering to remove noise from the image.

[0058] Median filtering is effective at removing salt-and-pepper noise, and its formula is as follows:

[0059] Where g(x,y) is the filtered image, f(s,t) is the original image, and S xy It is the neighborhood centered at (x,y).

[0060] Gaussian filtering is suitable for removing Gaussian noise, and its formula is:

[0061] Where σ is the standard deviation, noise reduction is achieved through convolution operations to improve image quality and avoid noise interference with subsequent analysis.

[0062] The aforementioned salt and pepper noise, also known as impulse noise or switching noise, is a common type of image noise, characterized by randomly appearing white and black pixels in an image. This noise typically originates from errors during image acquisition, transmission, or storage, such as sensor malfunctions, bit errors during transmission, or data reading errors.

[0063] In an image, salt-and-pepper noise manifests as pixels that suddenly become very bright (white) or very dark (black), creating a strong contrast with the normal grayscale values ​​of surrounding pixels. These aberrations occur randomly, scattered throughout the image rather than clustered in any particular area.

[0064] Step S14: Based on the target image information, determine whether the fit between the grounding device and the conductor meets the requirements.

[0065] In the technical solution provided by step S14 of the present invention, the above judgment process is mainly based on the calculation of the fitting degree based on image features and shape features, and the obtained value is compared with a preset threshold.

[0066] Among them, the fitting degree judgment based on image features:

[0067] The Canny edge detection algorithm is used to obtain the set of edge pixels A (where the first and second clamps are in contact) and the set of edge pixels B (where the wire is in contact). The algorithm first smooths the image using a Gaussian filter, then calculates the gradient magnitude.

[0068] Among them G x It is the gradient in the horizontal direction, G y It is the gradient in the vertical direction, and the direction angle. The edges are then obtained through nonmaximum suppression and double thresholding.

[0069] Calculate the number of overlapping edge pixels cC = A∩B, and define the fit index:

[0070] Taking into account different types of grounding clamps and conductors, as well as the site conditions under various working and abnormal circumstances, a threshold of 0.8 is set. If the value is below the set threshold of 0.8, it indicates that the fit may be poor.

[0071] Gap detection ratio:

[0072] Gap width threshold: Based on the manufacturing precision of the grounding clamp and conductor, and the acceptable gap size in actual operation, the width threshold for the continuous blank pixel area (gap) is determined to be 5 pixels. This value takes into account image resolution, possible installation errors, and the maximum permissible gap that will not significantly impede current conduction.

[0073] Gap length ratio threshold: Based on the analysis of the circumference of various conductor specifications and grounding safety standards, a gap length exceeding 10% of the conductor circumference is set as the standard for judging poor fit. This is because when the gap length reaches this ratio, it significantly increases the grounding resistance and affects the grounding effect.

[0074] Fit determination based on shape features:

[0075] Contour similarity calculation: extract the contour of the part of the first clamp that contacts the wire, denoted as P1; extract the contour of the part of the second clamp that contacts the wire, denoted as P2.

[0076] Using the Hausdorff distance: d H(P1,P2)=max{h(P1,P2),h(P2,P1)} (6)

[0077] in, Measure the difference in their contours. Set the threshold to 10 pixels; if d H If (P1,P2) is greater than the set threshold, there is a problem with the fit.

[0078] Area ratio determination:

[0079] Calculate the actual contact area S1 (estimated by the number of pixels) of the area where the grounding clamp and the conductor are in contact and the contact area S2 (calculated based on the standard dimensions of the grounding clamp and the conductor) under ideal contact conditions.

[0080] Define the area fit index: The threshold is set to 0.9. If the value is less than the set value of 0.9, the fit is considered insufficient.

[0081] Step S16: If it is determined that the fit between the grounding device and the conductor does not meet the requirements, an alarm command is generated. The alarm command is used to control the target device to issue an alarm.

[0082] In the technical solution provided in step S16 of the present invention, information is output to the monitoring system or mobile terminal based on the fitting degree judgment result. If the fitting degree is determined to be unsatisfactory, an alarm mechanism is triggered, and maintenance personnel are notified to handle the issue promptly via sound, SMS, APP push, or other means.

[0083] The aforementioned target device can be a light emitter or a sound emitter.

[0084] Based on the judgment result, information is output, and an alarm is triggered when the fit is insufficient. Simultaneously, relevant images and detection information are recorded in the monitoring system for easy viewing and analysis by maintenance personnel. This invention enables automated and accurate detection of the fit between the grounding clamp and the conductor, improving the operational safety of the power system.

[0085] Through the above steps, this method can acquire image information of the grounding wire clamping the conductor in real time, quickly determine the fit, and immediately generate an alarm command once the fit is found to be unsatisfactory. This enables real-time monitoring of the power system's grounding status and rapid response to abnormal situations, significantly improving the system's safety and reliability. By image preprocessing and fit judgment based on target image information, this method automates grounding wire fit detection, avoiding the subjectivity and errors of manual inspection and ensuring the objectivity and accuracy of the detection. Especially for tiny gaps or poor contact that are difficult to detect with the naked eye, image analysis can provide more accurate judgments.

[0086] Optionally, based on the target image information, it is determined whether the fit between the grounding device and the conductor meets the requirements, including:

[0087] Step S141: Obtain image feature information and shape feature information of the target image information, wherein the image feature information includes at least: edge pixel information of the first clamp and the second clamp, and edge pixel information of the wire, and the shape feature information includes at least: contour information of the contact portion between the first clamp and the wire, and contour information of the contact portion between the second clamp and the wire.

[0088] In the technical solution provided in step S141 of the present invention, the acquired image feature information and shape feature information enable the system to comprehensively evaluate the bonding state of the grounding wire and the conductor from two dimensions: edge pixels and contour. This multi-dimensional evaluation method can more accurately reflect the actual bonding situation and avoid misjudgments that may be caused by a single indicator.

[0089] Step S142: Obtain the edge fitting index based on image feature information.

[0090] In the technical solution provided by step S142 of the present invention, the edge fit index is calculated based on image feature information. By quantifying the degree of overlap between the edges of the first and second clamps and the edge of the conductor, the edge fit status of the contact area can be accurately determined. When the edge fit index is lower than a first preset value, it indicates that the edges of the grounding wire and the conductor are not aligned sufficiently, which may result in poor contact or excessive gap, affecting the grounding effect.

[0091] Step S143: Obtain the area fit index based on shape feature information.

[0092] In the technical solution provided in step S143 of the present invention, the area fit index is calculated based on shape feature information. By comparing the actual contact area with the contact area under ideal fit conditions, the fit between the grounding wire and the conductor is evaluated. When the area fit index is less than a second preset value, it means that the contact area is insufficient to ensure good conductivity, which may increase the grounding resistance and reduce the efficiency of the grounding wire.

[0093] Step S144: Determine whether the edge fit index is less than the first preset value and whether the area fit index is less than the second preset value.

[0094] Optionally, if it is determined that the fit between the grounding device and the conductor does not meet the requirements, an alarm command is generated, including:

[0095] Step S161: If the edge fit index is less than the first preset value, or the area fit index is less than the second preset value, generate an alarm command. The alarm command is used to control the target device to issue an alarm.

[0096] In the technical solution provided by step S161 of the present invention, by immediately comparing the edge fit index and the area fit index with a preset threshold, the system can instantly determine whether the grounding wire fit meets the requirements. Once insufficient fit is detected, an alarm command is immediately generated to ensure that abnormal situations can be handled in a timely manner and to avoid safety hazards caused by poor grounding.
