Description

Technical Field

[0001] The present invention relates to data processing technology, and in particular to a multi-dimensional processing method and system for cross-linked cable production. Background Art

[0002] Cross-linked power cables are equipment used for distributing electrical energy in distribution lines with an industrial frequency rated voltage of 3.6 / kV-26 / 35kV. In the field of modern power transmission, cross-linked cables are widely used in urban power grids, industrial facilities, high-rise buildings and other scenarios due to their excellent electrical properties, mechanical strength and high-temperature resistance. With the expansion of cable production scale and the increase in application demand, the quality control of cross-linked cables is particularly critical. During the production process, high-precision testing methods are required to promptly detect surface and internal defects of the cable to ensure that the cable quality meets the safety operation standards.

[0003] At present, the existing cross-linked cable defect detection technology has many shortcomings. On the one hand, traditional detection methods mostly use a single detection device or simple manual sampling, which is difficult to fully cover the complex structure and potential defects of the cable. For example, manual visual inspection is easily affected by subjective factors and has limited ability to identify minor defects, while single sensor detection can only obtain local data and cannot present the overall defect distribution of the cable. On the other hand, the versatility of existing detection equipment is poor and it is difficult to adapt to the detection needs of different types of cables. For special specifications or special-shaped cables, it is often necessary to replace the detection device or adjust the detection parameters, resulting in low detection efficiency. In addition, the processing method of detection data is relatively extensive, lacking accurate analysis of defect location, morphology and severity, and cannot provide effective guidance for production process optimization. It is difficult to meet the refined requirements of quality control in modern cable production.

[0004] Therefore, how to conduct refined inspections on cross-linked cables of different models and improve inspection efficiency has become an urgent problem to be solved. Summary of the Invention

[0018] The beneficial effects of the present invention are as follows: 1. The present invention can perform refined detection on cross-linked cables of different models and improve detection efficiency. First, the present invention matches the annular detection device by cable model and constructs an annular positioning image in combination with the positioning mark, thereby achieving precise adaptation of the detection device and precise positioning of the defect position. The present invention can automatically match the circular detection space composed of the detection probe according to the cable model to ensure that the detection device is highly consistent with the cable specifications. When the annular detection device has a positioning mark, the accurate position of each pressure detection unit is determined by the angle position and the numbering sequence. The overlapping unit of the positioning mark is used as the starting point, and the detection layout is constructed according to the preset numbering direction and unit angle. The pressure detection unit number is associated one by one with the annular image display slot, providing precise spatial coordinates for subsequent defect positioning, significantly improving the comprehensiveness and accuracy of the detection.

[0019] 2. The present invention can realize defect visualization through dynamic data processing, wherein, by collecting pressure data in real time and combining it with algorithm processing, the abstract pressure change is converted into a visual and quantitative defect graph, thereby realizing in-depth analysis of cable defects. During the detection process, the first detection value after the pressure detection unit is powered on is first obtained as a reference. When the cable passes through the detection space, the second detection value is collected in real time. The direction and height of the defect are determined by calculating the difference between the two. When the numerical difference is positive, the defect is determined to be a protrusion in the outer direction of the ring. The protrusion height is calculated according to the difference and the preset conversion ratio, and a visual defect graph is generated at the corresponding position of the annular positioning image to form the first defect data. Further, by stretching and splicing adjacent defect data, discrete defects are integrated into complete detection defect data, and the continuous distribution state of defects is intuitively presented. Through dynamic data processing, not only the visual presentation of defects is realized, but also a precise basis for defect severity assessment is provided through quantitative analysis, effectively improving the depth and efficiency of defect detection.

[0020] 3. The present invention aims at the situation of special specification cables or mismatched models, and realizes full coverage and flexible adaptation of detection scenarios through the innovative combination of semi-ring detection devices. When there is no suitable annular detection device, four radius-adapted semi-ring detection devices can be selected according to the cable radius, and the opening directions can be adjusted to the top, bottom, left, and right respectively to form an all-round detection array. When detecting small diameter cables or special-shaped cables, the four semi-ring devices fit tightly to the cable surface from different directions, generate a semi-ring positioning image by determining the position of the pressure detection unit, and update the pressure data in real time to detect defects. Through the collaborative working mode of multi-form detection devices, not only the detection problem of special specification cables is solved, but also the detection blind area of ​​the cable surface is reduced through horizontal spacing and direction adjustment, which greatly expands the application range of the detection method. At the same time, the flexible combination of semi-ring devices reduces the equipment investment cost, improves the adaptability of the detection system to complex production scenarios, and provides a reliable technical guarantee for the full-scene quality control of cross-linked cables.

DETAILED DESCRIPTION

[0022] The following specific embodiments are used to describe the technical solution of the present invention in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0023] like Figure 1 As shown, the present invention provides a multi-dimensional processing method for cross-linked cable production, comprising: S1. Match an annular detection device according to the model of the detection cable. The annular detection device includes a circular detection space formed by a plurality of detection probes and a pressure detection unit connected to the detection probes.

[0024] It is understandable that since the thickness of the cross-linked cable can be different, the corresponding cross-linked cables have multiple models. In order to improve the accuracy of the test results, the corresponding annular detection device can be matched according to the model of the detection cable, so that when the detection cable is subsequently tested, the detection cable can pass through the circular detection space smoothly, and the corresponding detection probe can be normally retracted, thereby improving the accuracy of the pressure detection unit value.

[0025] Among them, the detection cable is a cross-linked cable that needs to be detected for defects, the annular detection device is an annular device for performing defect detection on the surface of the detection cable, the detection probe is a probe for performing pressure detection on the detection cable, the circular detection space is a circular space formed by the detection probes, and the subsequent detection cable can pass through the circular detection interval for defect detection. The pressure detection unit is a unit module that receives pressure values, such as a pressure sensor.

[0026] Through the above-mentioned implementation manner, the present invention can determine the ring detection device corresponding to the detection cable, so as to subsequently use the determined ring detection device to perform defect detection on the detection cable, thereby improving detection accuracy.

[0027] S2, acquiring the detection position of each of the pressure detection units, and generating a ring-shaped positioning image according to the detection position.

[0028] It is understandable that since there are a large number of pressure detection units on the annular detection device, and the angle of placement of the annular detection device is different each time, the position of the pressure detection unit will change. When the detection cable is subsequently inspected, the position of the pressure detection unit will be uncertain, resulting in the inability to accurately determine the position of the surface defect of the detection cable. The detection position of the pressure detection unit can be obtained, so that the defect position corresponding to the abnormal pressure value of each pressure detection unit when inspecting the cable can be determined based on the detection position, thereby improving the detection accuracy.

[0029] The detection position is the azimuth position corresponding to the pressure detection unit, and the annular positioning image is the annular image for determining the pressure detection unit.

[0030] In some embodiments, a specific implementation of step S2 (obtaining the detection position of each of the pressure detection units and generating a ring-shaped positioning image based on the detection position) includes: S21: When it is determined that the annular detection device has a positioning mark, the angular position corresponding to the positioning mark is obtained, and the detection position of each of the pressure detection units is determined based on the angular position.

[0031] It can be understood that when there is a positioning mark on the annular detection device, such as a vertical line mark marked on the annular detection device, the current angular position of the mark can be obtained, such as the angular position corresponding to 1 o'clock, so that the angular position of the positioning mark can be used as the starting position in the future, thereby determining the detection position of the remaining pressure detection units, making the determination of the detection position more directional and accurate, so that a more realistic annular positioning image can be generated subsequently.

[0032] The positioning mark is a mark on the annular detection device for determining the position of the pressure detection unit, for example, Figure 2 As shown, it can be a bold vertical line mark on the ring detection device, and the angular position is the position of the angular orientation corresponding to the positioning mark.

[0033] In some embodiments, a specific implementation of step S21 (determining the detection position of each of the pressure detection units based on the angular position) includes: S211 , taking the pressure detection unit overlapping with the position of the positioning mark as the starting detection unit, and determining the angular position as the starting position of the starting detection unit.

[0034] It can be understood that after determining the angular position, the pressure detection unit overlapping with the positioning mark position is set as the starting detection unit, and the angular position is determined as the starting position of the starting detection unit. This implementation method clarifies the starting detection unit and its starting position, and provides a reference point for the subsequent determination of the positions of other pressure detection units, so that the position determination of each pressure detection unit has a clear starting reference, which helps to determine the positions of other units in a more orderly manner and ensure the standardization and accuracy of the detection position determination process.

[0035] The starting detection unit is a pressure detection unit that overlaps with the position of the positioning mark, and the starting position is a position corresponding to the starting detection unit.

[0036] S212: Obtain a numbering sequence corresponding to each of the pressure detection units, determine the first number in the numbering sequence as the starting number of the starting detection unit, and associate the starting number with a starting position.

[0037] It can be understood that in order to facilitate the subsequent determination of the corresponding detection position of each pressure detection unit, the pressure detection units can be numbered so that the numbers and detection positions correspond to each other, so as to facilitate the subsequent determination of the defect image of the corresponding position according to the pressure detection unit corresponding to the number, so as to realize defect detection of the detection cable.

[0038] The numbering sequence is an arrangement sequence of numbers corresponding to the pressure detection units, that is, a sequence obtained by statistically arranging the numbers corresponding to the pressure detection units, and the starting number is the number corresponding to the starting detection unit.

[0039] It is not difficult to understand that through the above implementation method, the numbering information of the starting detection unit is clarified, making the identification of the starting detection unit clearer, and through the association with the starting position, a correspondence between the number and the position is established, which provides a basis for subsequent determination of the position of other pressure detection units based on the number, helps to more accurately combine the number with the actual position, and improves the accuracy and traceability of position determination.

[0040] S213 , sequentially obtaining the detection position of each pressure detection unit based on the preset numbering direction, the starting position, and the preset unit angle.

[0041] It can be understood that the preset numbering direction is a pre-set numbering direction, such as a clockwise direction, which provides directional guidance for determining the position of each unit. The starting position is used as a reference point. The preset unit angle is the interval angle between each pressure detection unit, which is predetermined and further clarifies the positional relationship between each unit. Through the combination of these three elements, the specific position of each pressure detection unit can be determined more accurately, making the position determination of the pressure detection unit more systematic and accurate, so as to generate an accurate annular positioning image.

[0042] S214: After removing the starting number from the number sequence, associate the detection positions one by one.

[0043] It can be understood that after determining the detection position of each pressure detection unit, the starting number is removed from the numbering sequence, and then the remaining numbers are associated with the corresponding detection positions one by one. This step processes the numbering sequence. After removing the starting number, the other numbers are associated with the corresponding detection positions, making the correspondence between the numbers and positions clearer and more definite, further improving the accuracy and completeness of the pressure detection unit position information, and providing an accurate reference basis for subsequent cable defect detection based on the number and position information, which helps to locate and analyze cable defects more efficiently. It should be noted that when there is no positioning mark on the annular detection device, a position verification device corresponding to the detection cable model can be selected, such as a cylindrical rod with the same thickness as the detection cable and a spiral depression on it, so that the initial azimuth angle can be selected and recorded as the starting angle, such as the angle position corresponding to directly above, and the position of the starting point of the spiral depression on the position verification device, that is, the cylindrical rod, is aligned with the starting angle of the annular detection device, and the cylindrical rod is controlled to pass through the annular detection device, and the pressure value of the corresponding pressure detection unit is recorded in real time, wherein the currently detected depression position is the detection position of the pressure detection unit corresponding to the minimum pressure value, so that the corresponding pressure detection units can be numbered in sequence with the starting position as the reference position, and the pressure detection units and detection positions can be associated, thereby obtaining the detection position corresponding to each pressure detection unit.

[0044] S22: Generate a ring-shaped positioning image according to the detection position corresponding to the pressure detection unit.

[0045] It can be understood that generating an annular positioning image based on the determined detection position of the pressure detection unit is a key step in converting the position information into a visual image, so as to intuitively present the distribution of the pressure detection unit on the annular detection device, provide a clear visual basis for the subsequent analysis of cable surface defects based on the image, and improve the accuracy and intuitiveness of the detection.

[0046] In some embodiments, a specific implementation of step S22 (generating an annular positioning image according to the detection position corresponding to the pressure detection unit) includes: S221: Generate an annular image corresponding to the annular detection device, where the annular image includes a plurality of display slots corresponding to pressure detection units.

[0047] It can be understood that by generating an annular image corresponding to the annular detection device and setting multiple display slots corresponding to the pressure detection units in the image, preparation is made for subsequently presenting the position information of the pressure detection units in a visual manner.

[0048] Among them, the annular image is the shape image corresponding to the annular detection device, and the display slot is the display slot for displaying the pressure detection unit number, which provides a corresponding display area for the position of the pressure detection unit, so that the pressure detection unit has a clear position representation in the annular image, providing a basic framework for subsequent associated numbering sequence and image positioning, and helping to more clearly display the distribution of the pressure detection unit.

[0049] S222: Rotate and position the annular image according to the angular position of the positioning mark.

[0050] It is understandable that if Figure 3 As shown, since the angular position of the positioning mark in the generated annular image is different from the angular position of the positioning mark corresponding to the actual annular detection device, the annular image can be rotated according to the positioning mark of the actual annular detection device so that the annular image matches the angular position of the actual annular detection device.

[0051] Through the above implementation, it is ensured that the position of the pressure detection unit in the annular image corresponds to the position in the actual device, which improves the accuracy and reliability of the image, makes the cable defect detection based on the annular image more in line with the actual situation, and provides an accurate image basis for the subsequent accurate analysis of cable surface defects.

[0052] S223, displaying the numbering sequences one by one in the display slots to obtain a ring-shaped positioning image.

[0053] It is understandable that the numbering sequences are displayed one by one in association on the corresponding display slots, so that each pressure detection unit has a clear number identification in the annular positioning image.

[0054] Through the above-mentioned association method, the position and numbering relationship of the pressure detection unit in the annular image are further clarified, which facilitates the subsequent analysis of the pressure data on the cable surface according to the numbering and position information, helps to more efficiently locate the defect position on the cable surface, and improves the accuracy and efficiency of detection.

[0055] S3, receiving the pressure data of the pressure detection unit in real time, updating the annular positioning image according to the pressure data, generating first defect data, and splicing adjacent first defect data to obtain detection defect data.

[0056] It can be understood that by receiving pressure data in real time and comparing it with the initial state, defect data is generated and spliced ​​and integrated, and finally complete defect detection data is formed, so that the detected pressure changes can be converted into visual defect graphics, thereby realizing accurate positioning and presentation of cable surface defects.

[0057] Among them, the pressure data is the pressure value corresponding to the sensed pressure of the pressure detection unit, the first defect data is the image data with the detection defect information displayed, and the detection defect data is the explosion image after splicing the corresponding first defect data.

[0058] In some embodiments, a specific implementation of step S3 (receiving pressure data from the pressure detection unit in real time, updating the annular positioning image according to the pressure data, generating first defect data, and splicing adjacent first defect data to obtain detected defect data) includes: S31 , responding to power-on information of the pressure detection unit, obtaining a current pressure value of the pressure detection unit as a first detection value based on the power-on information.

[0059] It is understandable that when the annular detection device is powered on, the pressure detection unit can be used normally to perform pressure detection on the detection cable to obtain pressure data, which is convenient for subsequent analysis of defect information on the surface of the detection cable.

[0060] Among them, the power-on information is the display information prompting that the pressure detection unit is powered on, the pressure value is the value corresponding to the pressure detection unit, the first detection value is the initial pressure value corresponding to the pressure detection unit, and the first detection value represents the baseline pressure state when the detection cable does not pass through the circular detection space, so as to subsequently determine whether there are defects on the cable surface.

[0061] S32, controlling the detection cable to pass through the circular detection space, and receiving the pressure value of the pressure detection unit in real time as a second detection value.

[0062] It can be understood that the control detection cable passes through the circular detection space and receives the pressure value (second detection value) of the pressure detection unit in real time. As the cable moves, the pressure detection unit continuously collects pressure changes at various points on the cable surface. These real-time data reflect the physical state of the cable surface. By continuously monitoring pressure changes, it is possible to capture pressure anomalies caused by defects such as bumps and depressions on the cable surface, providing dynamic data support for defect detection.

[0063] The second detection number is the pressure value detected when the detection cable passes through the circular detection space.

[0064] S33, determining a defect pattern based on the difference between the second detection value and the first detection value, and updating the annular positioning image based on the defect pattern to obtain first defect data.

[0065] It can be understood that by calculating the difference between the second detection value and the first detection value, the direction (outside the ring or inside the ring) and height (defect severity) of the defect pattern are determined. A positive difference indicates that there is a bulge on the cable surface (outside the ring), and a negative difference indicates that there is a depression (inside the ring). The larger the absolute value of the difference, the more obvious the defect.

[0066] It is not difficult to understand that the defect graphics generated based on these parameters are superimposed on the annular positioning image to form the first defect data. This process converts the abstract pressure value into an intuitive graphical representation, making the defect location and degree clear at a glance, and providing a visual image for subsequent defect splicing and analysis.

[0067] Among them, the numerical difference is the difference between the second detection value and the first detection value, the defect pattern is a pattern representing the surface defect of the detection cable, such as a convex pattern and a concave pattern, and the first defect data is the image data of the defect pattern updated in the annular positioning image.

[0068] In some embodiments, a specific implementation of step S33 (determining the defect pattern based on the difference between the second detection value and the first detection value) includes: S331, determine the positive or negative value of the numerical difference between the second detection value and the first detection value. When the numerical difference is positive, determine that the defect direction is outside the ring; when the numerical difference is negative, determine that the defect direction is inside the ring.

[0069] It can be understood that the defect direction is determined by judging the positive and negative values ​​of the numerical difference, and a mapping relationship between the pressure change and the physical defect direction is established. When the numerical difference is positive, it indicates that the pressure of the detection cable surface on the detection probe increases, and there are protrusions on the corresponding cable surface (such as bulges, impurities, etc.). Therefore, the defect direction is outside the ring. Conversely, when the numerical difference is negative, it indicates that the pressure decreases, and there are depressions on the corresponding cable surface (such as scratches, damage, etc.), and the defect direction is inside the ring. This judgment logic provides a direction reference for the subsequent generation of defect graphics, ensuring that the physical form of the defect can be correctly represented.

[0070] Among them, the defect direction is the convex and concave direction of the defect on the detection cable surface, the out-of-ring direction is the direction pointing to the outside of the ring along the line connecting the detection position of the detection probe and the center point of the circular image, and the in-ring direction is the direction pointing to the inside of the ring along the line connecting the detection position of the detection probe and the center point of the circular image.

[0071] S332: Obtain a defect height based on the absolute value of the product of the numerical difference and a preset conversion ratio.

[0072] It can be understood that the quantitative mapping of pressure changes to physical heights is achieved through a preset conversion ratio. The preset conversion ratio is a coefficient pre-set according to the characteristics of the detection device and the cable material characteristics. It is used to convert the pressure difference into a height value with actual physical meaning. By taking the absolute value of the product, it is ensured that the defect height is always positive, which is convenient for subsequent graphics generation.

[0073] The defect height is the height of the concave and convex defects on the surface of the detection cable.

[0074] Through the above implementation, abstract pressure data is converted into intuitively understandable physical dimensions, providing a quantitative basis for evaluating the severity of defects.

[0075] S333: Generate a defect pattern according to the outer ring direction or the inner ring direction and the defect height.

[0076] It can be understood that the drawing direction of the graphic is determined according to the direction outside or inside the ring, and the size of the graphic is determined according to the height of the defect, and finally a visual mark that can intuitively reflect the surface defects of the cable is formed on the annular positioning image. This graphic generation process converts pressure data into visual information that can be directly recognized by the user, so that the operator can quickly locate the defect position and intuitively view the severity of the defect.

[0077] S34, stretching and splicing the adjacent first defect data to obtain detection defect data.

[0078] It can be understood that by splicing and integrating adjacent first defect data, complete detection defect data is formed, solving the problem of continuous display of discrete defect data. This step connects the scattered defect information into a coherent defect area through stretching and splicing operations, more accurately reflecting the actual defect situation on the cable surface, and providing a more comprehensive basis for subsequent defect analysis and repair.

[0079] In some embodiments, a specific implementation of step S34 (stretching and splicing adjacent first defect data to obtain detected defect data) includes: S341: Classify the adjacent first defect data to obtain a spliced ​​set.

[0080] It can be understood that in order to make the received detection defect data consistent with the actual detection cable, the adjacent first defect data can be classified according to the detection time to obtain a splicing set, so that the first defect data in the splicing set can be subsequently spliced ​​so that the surface defects of the detection cable can be intuitively displayed.

[0081] The splicing set is a set of adjacent first defect data.

[0082] S342 , performing thickness stretching on each first defect data in the splicing set according to the stretching thickness to obtain stretched defect data.

[0083] It can be understood that the stretched thickness is the thickness data of the first defect data stretched to show the thickness, which is a preset parameter used to expand the spatial dimension of the defect data, such as Figure 4 As shown, through the stretching operation, the original two-dimensional defect data is expanded into a three-dimensional area with a certain thickness, making the defect more visually obvious and easier to splice, thereby enhancing the visualization effect of the defect.

[0084] The stretched defect data is image data obtained by performing thickness stretching on the first defect data.

[0085] S343, determining the center point of each stretch defect data, and sequentially splicing adjacent stretch defect data according to the center point to obtain detection defect data.

[0086] It can be understood that the center point is the image center point of the stretched defect data, which provides a reference benchmark for splicing. By arranging adjacent defect data in spatial order according to the center point, it ensures that the spliced ​​defect data can accurately reflect the continuous distribution of defects on the cable surface. This step will eventually integrate the scattered defect information into a complete defect area to form defect detection data, providing operators with a more intuitive and comprehensive defect view, which is convenient for evaluating cable quality.

[0087] It should be noted that due to the small radius of the detection cable, there may not be a corresponding matching ring detection device. Therefore, multiple half-ring detection devices with larger radii can be selected to perform defect detection on the detection cable. The specific method is as follows, which also includes: A1: When the model of the detection cable is not matched, the cable radius of the detection cable is obtained, and a semi-ring set is determined according to the cable radius.

[0088] It is understandable that when a suitable ring detection device is not matched, in view of the situation where the radius of the detection cable is small, the set of semi-ring detection devices is determined by obtaining the cable radius, so as to provide the prerequisite for the subsequent use of the semi-ring detection device to detect defects in the cable, ensuring that when the ring detection device cannot be used, a suitable detection device can still be found to detect the cable, thereby improving the adaptability and flexibility of the detection.

[0089] The cable radius is the radius of the detection cable, and the semi-ring set is a set of semi-ring detection devices that can be nested on the corresponding circular ring of the detection device.

[0090] In some embodiments, a specific implementation of step A1 (determining a semi-ring set according to the cable radius) includes: A11, obtaining the radius difference between each semi-ring detection device and the cable radius, and determining the semi-ring detection device with a radius greater than or equal to the cable radius and the smallest radius difference as the target semi-ring.

[0091] It can be understood that by obtaining the radius difference between each semi-ring detection device and the cable radius, the semi-ring detection device with a radius greater than or equal to the cable radius and the smallest radius difference is found as the target semi-ring, so that the target semi-ring can be selected based on the radius difference, ensuring that the selected semi-ring detection device can fit the detection cable as closely as possible, making the detection more accurate, and at the same time meeting the size requirements of the detection cable, thereby improving the adaptability of the semi-ring detection device and the detection cable.

[0092] Among them, the semi-ring detection device is a device with a semi-ring shape, the radius difference is the difference between the radius of the semi-ring detection device and the radius of the cable, and the target semi-ring is the semi-ring detection device selected for detecting the detection device.

[0093] A12, matching the four target semirings to obtain a semiring set.

[0094] It can be understood that by selecting four target semi-rings to form a set of semi-ring detection devices, these semi-ring detection devices will subsequently jointly detect the detection cable and detect the cable from different directions to ensure that all parts of the cable surface can be detected, thereby improving the comprehensiveness of the detection.

[0095] A2, the semi-ring set includes four semi-ring detection devices with the same radius, and the semi-ring detection device includes a semi-circular detection space formed by multiple detection probes, and a pressure detection unit connected to the detection probes.

[0096] As can be understood, the semi-circular detection device consists of multiple detection probes forming a semi-circular detection space, equipped with a pressure detection unit connected to the detection probes. The semi-circular detection space provides a detection area for the detection cable, while the pressure detection unit is used to receive pressure data, providing data support for subsequent defect detection based on pressure data, enabling the semi-circular detection device to detect cable defects.

[0097] The semicircular detection space is the area enclosed by the detection probes corresponding to the semicircular detection device.

[0098] A3, positioning the semi-ring detection devices one by one according to preset detection positions, wherein the preset detection positions are arranged horizontally at intervals.

[0099] It can be understood that the semi-ring detection devices are positioned one by one according to the preset detection positions, and the preset detection positions are arranged horizontally at intervals. The above positioning method ensures that the semi-ring detection devices are regularly distributed in the horizontal direction, so that they can detect the detection cables from different positions and cover the surface of the detection cables as much as possible, while ensuring the orderliness and standardization of the detection.

[0100] The preset detection position is a pre-set position where the half-ring detection device performs detection on the detection cable.

[0101] A4, adjust the opening direction of the semi-ring detection device to the preset detection direction of the corresponding preset detection position, and the preset detection direction includes the upward direction, the downward direction, the left direction and the right direction.

[0102] It can be understood that the opening direction of the semi-ring detection device is adjusted to be consistent with the preset detection direction of the corresponding preset detection position. The preset detection directions include the upper, lower, left and right directions. By adjusting the opening direction, the semi-ring detection device can detect the detection cable from different directions, fully covering the cable surface, improving the accuracy and completeness of the detection, and ensuring that defects in all directions on the cable surface can be detected.

[0103] The preset detection direction is a placement direction pre-set for each pre-detection position.

[0104] A5, determining the detection position of each of the pressure detection units, and generating a semi-circular positioning image according to the detection position.

[0105] It can be understood that the determination of the detection position provides position information for the subsequent defect location based on the pressure data. The generated semi-ring positioning image intuitively shows the distribution of the pressure detection unit, and provides a visual basis for the subsequent updating of the semi-ring positioning image and detection of defects based on the pressure data, so that the inspectors can have a clearer understanding of the detection conditions of the cable surface.

[0106] Among them, the semi-ring positioning image is the detection positioning image corresponding to the semi-ring detection device.

[0107] A6, receiving the pressure data of the pressure detection unit in real time, updating the semi-ring positioning image according to the pressure data, and generating defect data.

[0108] It is understandable that by receiving pressure data in real time, the pressure changes on the cable surface can be detected in a timely manner, and then the semi-ring positioning image can be updated according to the changes in the pressure data to accurately determine the location and condition of defects on the cable surface. The generated defect data provides specific data support for the subsequent analysis and processing of cable defects, which helps to improve the efficiency and accuracy of cable detection.
