[0042] Combination Figure 1 to Figure 2 As shown, according to a specific embodiment of the present invention, a grounding wire device is provided.

[0043] Specifically, Figure 1 , Figure 2 As shown, the grounding wire device includes: a wiring portion 10, the wiring portion 10 has a first clamp 11 with an opening on one side, and the first clamp is used to place the wire; a movable portion 20, the movable portion 20 is movably connected to the wiring portion 10, the movable portion 20 has an initial position away from the first clamp 11, and the movable portion 20 has a working position matched with the first clamp 11, when the movable portion 20 is in the working position, the movable portion 20 and the first clamp 11 are enclosed to form a clamping space for clamping the wire; an image processing device 30, the image processing device 30 is arranged on the wiring portion 10, and the image processing device 30 is used to obtain image information of the movable portion 20 and the first clamp 11 clamping the wire, and detect the fit between the wire and the wiring portion 10 and the movable portion 20 based on the image information.

[0044] In this embodiment, through the movable connection between the movable part 20 and the wiring part 10, the grounding wire device can quickly switch between the initial position and the working position to achieve rapid clamping and release of the wire. This arrangement improves the efficiency of installation and removal of the grounding wire and reduces the operation time. Especially in emergency situations or scenarios requiring frequent operations, it can respond quickly and improve safety. The image processing device 30 can obtain image information of the movable part 20 and the first clamp 11 clamping the wire, and based on the image analysis technology, real-time detection of the fit between the wire and the wiring part 10 and the movable part 20. This real-time monitoring function can immediately feedback the installation status of the wire, promptly detect poor fitting, avoid safety hazards caused by poor contact of the grounding wire, and improve the accuracy and timeliness of detection.

[0045] It should be noted that, when the movable portion 20 is located at the working position, the movable portion 20 is connected to the first clamp 11 , or the movable portion 20 is in contact with the first clamp 11 .

[0046] Furthermore, the wiring portion 10 includes: an accommodating portion 12, which is arranged on a side away from the first clamp 11, and the accommodating portion 12 has an accommodating cavity 121 for the movable portion 20 to pass through; wherein the movable portion 20 is rotatably connected to the accommodating portion 12, and the movable portion 20 is operated to rotate so that the movable portion 20 switches between the initial position and the working position.

[0047] Specifically, the movable portion 20 is rotatably connected to the accommodating portion 12, so that the movable portion 20 can be freely switched between the initial position and the working position. This design increases the flexibility of the device, allowing the operator to flexibly adjust the angle of the movable portion 20 according to the specific position and direction of the wire to achieve the best clamping effect.

[0048] Furthermore, the movable part 20 includes: a movable rod 21, which is movably arranged in the accommodating 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 arranged along the circumference of the movable rod 21, one end of the elastic member 23 abuts against the second clamp 22, and one end of the elastic member 23 abuts against the outer wall of the accommodating part 12.

[0049] Specifically, when the movable rod 21 is in the initial position, the elastic member 23 is in a compressed state; when the movable rod 21 is in the working position, the elastic member 23 is in a released state. The setting of the elastic member 23 can realize the automatic resetting of the movable rod 21 in the absence of external force. When the operator rotates to release the movable rod 21, the elastic member 23 can push it back to a locking state that cooperates with the first clamp 11, ensuring that the wire is firmly clamped.

[0050] At the same time, the second clamp 22 is movably connected to one end of the movable rod 21, so that when the operator operates the movable rod 21 to rotate, the movable rod 21 will not drive the second clamp 22 to rotate. The second clamp 22 always maintains a position and posture that cooperates with the first clamp 11, ensuring the reliability of clamping the wire.

[0051] In this embodiment, the elastic member 23 is a compression spring. In other embodiments, the type of the elastic member 23 is not limited thereto.

[0052] Further, the accommodating portion 12 includes: a bottom shell 122, one end of which is provided with a first clamp 11; a frame body 123, which is provided on the bottom shell 122, the frame body 123 is provided at a distance from the first clamp 11, and at least two threaded grooves 1231 are provided on the frame body 123, at least two threaded grooves 1231 are provided at intervals in the horizontal direction, and at least two threaded grooves 1231 are provided to communicate with the accommodating cavity 121; wherein, the elastic member 23 is provided between the second clamp 22 and the frame body 123, one end of the elastic member 23 abuts against the second clamp 22, and the other end of the elastic member 23 abuts against the outer wall of the frame body 123.

[0053] Furthermore, a threaded protrusion 211 is provided on the movable rod 21. 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 clamp 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 clamp 11.

[0054] 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 clamp 22 and the first clamp 11 when the movable rod 21 moves 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.

[0055] Furthermore, the movable part 20 also includes: an insulating rod 24, one end of the insulating rod 24 is movably connected to the movable rod 21, and the other end of the insulating rod 24 is provided with a wire take-up drum 26; a locking piece 25, the locking piece 25 has a locking groove, the locking piece 25 is arranged on one side of the wire take-up drum 26, the locking piece 25 has a locking state for locking the wire into the locking groove, and the locking piece has an unlocking state for unlocking the wire.

[0056] Specifically, when in use, the elastic member 23 is controlled in a compressed state, and then the grounding wire device is uploaded to the tower, and the tail is hung on the tower through the locking member 25 to prevent it from falling. The camera unit 31 is opened, and the wire is hooked through the first clamp 11. The insulating rod 24 is rotated. After the tail thread is separated, it will move forward quickly through the elastic member 23 to tighten the threaded protrusion 211 of the movable rod 21 and the threaded groove 1231 close to the first clamp 11. After tightening, the camera unit 31 can take pictures in real time or control the picture taking.

[0057] Furthermore, a connecting block 221 is provided on one side of the second clamping head 22 facing the movable rod 21 , and the movable rod 21 is movably connected to the connecting block 221 .

[0058] Specifically, the connecting block 221 enables the second clamping head 22 to make a linear motion when the movable rod 21 makes a rotational motion, so as to maintain reliable contact with the first clamping head 11 .

[0059] Furthermore, the image processing device 30 includes: a camera unit 31, which is arranged on at least one side of the bottom shell 122 close to the first clamp 11, and the camera unit 31 is used to obtain image information of the first clamp 11 and the second clamp 22 clamping the wire; a data processing unit 32, which is communicatively connected to the camera unit 31, and the data processing unit 32 is used to judge the fit between the first clamp 11, the second clamp 22 and the wire based on the image information.

[0060] like Figure 3 According to another aspect of the present invention, a method for real-time identification of grounding wire fit is provided, which is performed using the grounding wire device of the above embodiment, and the method includes:

[0061] Step S10: Acquire image information of the grounding wire device clamping the wire.

[0062] In the technical solution provided in the above step S10 of the present invention, the above image information includes edge information and contour information of the contact area between the grounding wire device and the conductor, wherein the edge information includes first edge information of the contact area between the first clamp and the conductor, and second edge information of the contact area between the second clamp and the conductor, and the contour information includes first contour information of the contact area between the first clamp and the conductor, and second contour information of the contact area between the second clamp and the conductor.

[0063] In this embodiment, the camera unit 31 can collect pictures in real time or periodically. After obtaining the image information of the grounding wire device clamping the conductor in step S10, the image information is transmitted to the data processing unit 32. The data processing unit 32 determines the fit between the first clamp 11, the second clamp 22 and the conductor based on the image information.

[0064] Step S12: pre-process the image information to obtain target image information.

[0065] In the technical solution provided in the above step S12 of the present invention, the above preprocessing includes grayscale processing and denoising processing.

[0066] The above image information is initially in a color image state, which is converted into a grayscale image after preprocessing, and the grayscale value is obtained based on the grayscale image.

[0067] Specifically, the weighted average method is used, and the calculation formula is:

[0068] Gray=0.299R+0.587G=0.114B (1)

[0069] Among them: Gray is the gray value, R, G, B are the values ​​of the red, green, and blue channels in the color image respectively. This can reduce the amount of data for subsequent processing and highlight the texture and edge information of the image.

[0070] The above-mentioned denoising process uses methods such as median filtering or Gaussian filtering to remove noise in the image.

[0071] Median filtering has a good effect in removing salt and pepper noise. The formula is:

[0072]

[0073] Where g(x,y) is the filtered image, f(s,t) is the original image, S xy is the neighborhood centered at (x,y).

[0074] Gaussian filtering is suitable for removing Gaussian noise, and its formula is:

[0075]

[0076] Where σ is the standard deviation, and denoising is achieved through convolution operation to improve image quality and avoid noise interference in subsequent analysis.

[0077] The above-mentioned Salt and Pepper Noise, also known as impulse noise or switching noise, is a common type of image noise, which appears as random white and black pixels in the image. This noise usually originates from errors in the image acquisition, transmission or storage process, such as sensor failure, bit errors in transmission or data reading errors.

[0078] In an image, salt and pepper noise appears as some pixels suddenly becoming very bright (white) or very dark (black), which is in sharp contrast to the normal grayscale values ​​of the surrounding pixels. These abnormal pixels appear randomly, and they are scattered throughout the image rather than concentrated in a certain area.

[0079] Step S14: Based on the target image information, determine whether the fit between the grounding wire device and the conductor meets the requirements.

[0080] In the technical solution provided in the above step S14 of the present invention, the above judgment process mainly calculates the degree of fit based on image features and shape features, and the obtained value is compared with a preset threshold.

[0081] Among them, the fit judgment based on image features:

[0082] The Canny edge detection algorithm is used to obtain the edge pixel set A where the first chuck contacts the second chuck and the edge pixel set B of the wire. The algorithm first smoothes the image using a Gaussian filter and then calculates the gradient amplitude:

[0083]

[0084] Among them G x is the horizontal gradient, G y is the vertical gradient, the direction angle Then the edge is obtained through non-maximum suppression and double threshold processing.

[0085] Calculate the number of overlapping edge pixels cC = A∩B and define the fit index:

[0086]

[0087] Taking into account different types of grounding clamps and wires, different working conditions and on-site conditions under abnormal conditions, the threshold is set to 0.8. If it is lower than the set threshold of 0.8, it indicates that there may be a poor fit.

[0088] Gap detection ratio:

[0089] Gap width threshold: Based on the manufacturing accuracy of the grounding clamp and the wire and the acceptable gap size in actual operation, the continuous blank pixel area (gap) width threshold is determined to be 5 pixels. This value takes into account image resolution, possible installation errors, and the maximum allowable gap that will not significantly hinder current conduction.

[0090] Gap length ratio threshold: For gap length, after analyzing the circumference of various specifications of wires and grounding safety standards, a length exceeding 10% of the circumference of the wire is set as the standard for judging poor fit. Because when the gap length reaches this ratio, the grounding resistance will increase significantly, affecting the grounding effect.

[0091] Fit judgment based on shape features:

[0092] Contour similarity calculation is performed to extract the contour of the contact portion between the first clamp and the wire, which is recorded as P1, and to extract the contour of the contact portion between the second clamp and the wire, which is recorded as P2.

[0093] Using Hausdorff distance:

[0094] d H (P1,P2)=max{h(P1,P2),h(P2,P1)} (6)

[0095] in, Measure the difference between the two 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.

[0096] Area ratio judgment:

[0097] The actual contact area S1 (estimated by the number of pixels) between the grounding clamp and the conductor and the contact area S2 (calculated based on the standard size of the grounding clamp and the conductor) under the ideal fitting state are calculated.

[0098] Define the area fit index: The threshold is set to 0.9. If it is less than the set value 0.9, it is judged that the fit is insufficient.

[0099] Step S16: when it is determined that the fit between the grounding wire device and the conductor does not meet the requirement, an alarm instruction is generated, and the alarm instruction is used to control the target device to issue an alarm.

[0100] In the technical solution provided in the above step S16 of the present invention, information is output to the monitoring system or mobile terminal according to the above fit judgment result. If the fit is judged not to meet the requirements, an alarm mechanism is triggered to notify the maintenance personnel to handle it in time through sound, SMS, APP push, etc.

[0101] The target device mentioned above may be a light emitter or a sound emitter.

[0102] Information is output based on the judgment result, and an alarm is triggered when the fit is insufficient. At the same time, relevant images and detection information are recorded in the monitoring system, which is convenient for maintenance personnel to view and analyze. The present invention can realize automatic and accurate detection of the fit between the grounding wire clamp and the wire, thereby improving the safety of power system operation.

[0103] Through the above steps, the method can obtain the image information of the grounding wire device clamping the wire in real time, quickly make a fit judgment, and immediately generate an alarm command once it is found that the fit does not meet the requirements, so as to realize the real-time monitoring of the grounding state of the power system and the rapid response to abnormal situations, which significantly improves the safety and reliability of the system. Through image preprocessing and fit judgment based on target image information, the method realizes the automation of grounding wire fit detection, avoids the subjectivity and error of manual inspection, and ensures the objectivity and accuracy of detection. In particular, for small gaps or poor contact that are difficult to identify with the naked eye, image analysis can provide more accurate judgments.

[0104] Optionally, judging whether the fit between the grounding wire device and the conductor meets the requirement based on the target image information includes:

[0105] Step S141: acquiring image feature information and shape feature information of the target image information, wherein the image feature information at least includes: edge pixel information of the first chuck and the second chuck, and edge pixel information of the wire; the shape feature information at least includes: contour information of the contact portion between the first chuck and the wire, and contour information of the contact portion between the second chuck and the wire.

[0106] 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 ground wire and the conductor from two dimensions: edge pixels and contours. This multi-dimensional evaluation method can more accurately reflect the actual bonding state and avoid misjudgment caused by a single indicator.

[0107] Step S142: Obtaining an edge fit index based on the image feature information.

[0108] In the technical solution provided in the above step S142 of the present invention, the edge fit index is calculated based on the image feature information, and the edge fit state of the contact part can be accurately determined by quantifying the degree of overlap between the edges of the first chuck and the second chuck and the edge of the wire. When the edge fit index is lower than the first preset value, it indicates that the edge of the ground wire and the wire are not aligned enough, and there may be poor contact or too large a gap, which affects the grounding effect.

[0109] Step S143: Based on the shape feature information, obtain an area fit index.

[0110] In the technical solution provided in the above step S143 of the present invention, the area fit index is calculated based on the shape feature information, and the fit degree between the ground wire and the conductor is evaluated by comparing the actual contact area with the contact area in the ideal fit state. When the area fit index is less than the second preset value, it means that the contact area is not enough to ensure good conductivity, which may increase the grounding resistance and reduce the effectiveness of the grounding wire.

[0111] Step S144: determining whether the edge fit index is less than a first preset value and whether the area fit index is less than a second preset value.

[0112] Optionally, when it is determined that the fit between the grounding wire device and the conductor does not meet the requirement, an alarm instruction is generated, including:

[0113] Step S161: when it is determined that the edge fit index is less than the first preset value, or the area fit index is less than the second preset value, an alarm instruction is generated, and the alarm instruction is used to control the target device to issue an alarm.

[0114] In the technical solution provided in the above step S161 of the present invention, by immediately comparing the edge fit index and the area fit index with the preset threshold, the system can immediately determine whether the ground wire fit meets the requirements. Once insufficient fit is found, an alarm instruction is immediately generated to ensure that abnormal situations can be handled in a timely manner to avoid safety hazards caused by poor grounding.

[0115] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures".
