Description

Technical Field

[0001] The invention relates to the field of electric power equipment, and in particular to a cable. Background Art

[0002] Cables are commonly used materials in power engineering. In actual use, they are often connected as needed before use. The connection is made by gluing or other methods. For example, CN119017210A discloses a power cable joint polishing and processing device and a method of use, which includes a ring sleeved on the outer surface of the cable body, the outer surface of the ring is provided with a central clamping mechanism, and the central clamping mechanism also includes a transmission assembly connected to the first telescopic rod, and the transmission assembly is used to drive the clamping arc plate to clamp and fix the cable body.

[0003] CN119005278A discloses a cable joint state detection model training method and a cable joint state detection method, device, equipment, medium and program. The cable joint state detection model training method comprises: obtaining network model parameters of a neural network model to be trained; optimizing the network model parameters of the neural network model to be trained by using a PSO optimization algorithm to obtain target network model parameters; updating the network model parameters of the neural network model to be trained according to the target network model parameters to obtain a cable joint state detection model to be trained; training the cable joint state detection model to be trained according to cable joint state sample data to obtain a target cable joint state detection model; wherein the target cable joint state detection model is used to detect the cable joint state.

[0004] It can be seen that the prior art does not disclose the method of using adhesive connection, so some problems in this field need to be studied in depth. For example, it is currently impossible to perform targeted visual monitoring processing on whether the terminal connector of the cable body is blocked by the overflowing glue, which makes it difficult to determine whether the terminal connector of the cable body has poor contact or cannot be connected due to being blocked by the overflowing glue. Summary of the invention

[0005] In order to solve the technical problems in the related fields, the present invention provides a cable, which obtains a first curvature set by obtaining each curvature value of a standard contour curve of a cable body terminal joint, identifies the occupied image area of ​​the cable body terminal joint based on the grayscale imaging characteristics of the cable body terminal joint in a received content conversion image, and obtains each curvature value of the edge curve of the occupied image area to obtain a second curvature set, thereby providing key data for whether the subsequent cable body terminal joint is blocked by overflowing glue colloid, and when the ratio of the number of curvature values ​​in the second curvature set that is the same as the first curvature set value to the number of curvature values ​​in the first curvature set exceeds or equals to a set ratio threshold and there is an overlapping part in the occupied image areas respectively occupied by the cable body terminal joint and the overflowing glue colloid in the received content conversion image, it is determined that the cable body terminal joint is blocked by the overflowing glue colloid and a joint overflowing glue identification signal is issued, otherwise, it is determined that the cable body terminal joint is not blocked by the overflowing glue colloid and a joint overflowing glue non-identification signal is issued, thereby completing the reliable application of visual monitoring technology in the intelligent identification of the overflowing glue state of the cable body terminal joint.

[0006] According to the present invention, a cable is provided, including a cable body and a cable body terminal joint glue overflow identification system, the system comprising: An embedded camera is embedded in a vertical rod fixing a terminal connector of a cable body and faces the terminal connector of the cable body to perform a camera action to obtain a live camera picture corresponding to a current timestamp; A box filter device is disposed in the instrument box on the vertical pole and connected to the embedded camera, and is used to perform box filter processing on the received live camera picture to obtain and output a corresponding box filter image; An exponential enhancement device, connected to the box-type filter device and arranged on the left side of the box-type filter device, for performing image content enhancement processing based on exponential transformation on the received box-type filter image to obtain and output a corresponding exponentially enhanced image; a content conversion device, connected to the exponential enhancement device and disposed on the right side of the box-type filtering device, for performing Butterworth low-pass filtering on the received exponential enhancement image to obtain and output a corresponding content conversion image; An occlusion identification mechanism is arranged in the instrument box on the vertical rod and connected to the content conversion device, and is used to obtain each curvature value of the standard contour curve of the cable body terminal joint to obtain a first curvature set, identify the image area occupied by the cable body terminal joint based on the grayscale imaging feature of the cable body terminal joint in the received content conversion image, and obtain each curvature value of the edge curve of the occupied image area to obtain a second curvature set. When the ratio of the number of curvature values ​​in the second curvature set that is the same as the first curvature set to the number of curvature values ​​in the first curvature set exceeds or equals to a set ratio threshold and there is an overlapped portion in the occupied image areas respectively occupied by the cable body terminal joint and the overflowed glue in the received content conversion image, it is determined that the cable body terminal joint is occluded by the overflowed glue and a joint overflow identification signal is issued; otherwise, it is determined that the cable body terminal joint is not occluded by the overflowed glue and a joint overflow unidentified signal is issued; The occlusion identification mechanism is further used to identify the image area occupied by the overflowed glue based on the gray value distribution range corresponding to the overflowed glue.

[0007] It can be seen that the present invention has at least the following three important inventive concepts: Invention concept 1: Performing a camera action on the cable body terminal connector for glue overflow identification to obtain a live camera picture corresponding to the current timestamp, and successively performing box filter processing, image content enhancement processing based on exponential transformation, and Butterworth low-pass filter processing on the live camera picture to obtain a content conversion image with better image quality; Inventive concept 2: Obtaining each curvature value of the standard contour curve of the cable body terminal joint to obtain a first curvature set, identifying the image area occupied by the cable body terminal joint based on the grayscale imaging feature of the cable body terminal joint in the received content conversion image, and obtaining each curvature value of the edge curve of the occupied image area to obtain a second curvature set, thereby providing key data for whether the subsequent cable body terminal joint is blocked by the overflowed glue; Inventive concept three: when the ratio of the number of curvature values ​​in the second curvature set that are the same as the first curvature set to the number of curvature values ​​in the first curvature set exceeds or is equal to the set ratio threshold and there is an overlapping part in the occupied image areas respectively occupied by the cable body terminal joint and the overflowed glue in the received content conversion image, it is determined that the cable body terminal joint is blocked by the overflowed glue and a joint overflow identification signal is issued; otherwise, it is determined that the cable body terminal joint is not blocked by the overflowed glue and a joint overflow non-identification signal is issued.
