Description

TECHNICAL FIELD

[0001] The present application relates to the field of image detection, in particular to a cable comprehensive quality detection system and method. BACKGROUND

[0002] As the core component in the fields of power transmission, communication connection and mechanical transmission, the quality of cable directly determines the operation safety and service life of the related system, so it is of great significance to comprehensively detect the mechanical properties and surface quality of the cable.

[0003] In the existing cable quality detection technology, the mechanical property detection is mostly carried out by single direction tensile or fixed load loading method, which can only obtain the macroscopic parameters such as tensile strength and elongation of the cable as a whole, and cannot accurately analyze the independent stress characteristics of different layer structures (such as insulation layer, conductor layer and shielding layer) and the interlayer cooperative stress state, resulting in insufficient identification of the local mechanical property degradation caused by internal structural defects of the cable. At the same time, the surface quality detection mostly relies on manual visual inspection or single optical imaging, which can only qualitatively judge the surface scratches, depressions and other defects, and cannot quantify the influence of defects on the overall mechanical properties of the cable under stress state, resulting in the mutual fragmentation of surface quality and mechanical property evaluation.

[0004] In view of this, a cable comprehensive quality detection system and method are provided. SUMMARY

[0005] In view of the above problems, the present application provides a cable comprehensive quality detection system and method, which realizes multi-dimensional stress detection, correlates surface defects and mechanical properties, and improves the comprehensiveness and accuracy of cable quality evaluation, and is suitable for cable quality control in complex scenarios.

[0031] The central processing unit generates a test report based on the cable quality grade, quality coefficient, and related test data.

[0032] A second aspect of the present invention provides a method for comprehensive cable quality testing, comprising the following steps:

[0033] Obtain the basic parameter data of the cable, and determine the dimensions of each bearing surface of the cable, the installation data of the load unit, the grating data of the structured light, and the tensile force data applied by the load unit based on the basic parameter data;

[0035] Using any one load unit as the bearing side and at least one other load unit as the load side, a tensile force is applied to the bearing surface of the cable from the load side to the bearing side, thereby defining a plurality of detected surfaces including a first detection surface and a second detection surface;

[0036] Background light and structured light are emitted to the first and second detection surfaces respectively, the reflection signal of the structured light is obtained, and the structural model of each detection surface is obtained through three-dimensional reconstruction to determine the surface parameters and deformation parameters under the current load.

[0040] The theoretical deformation parameters are calculated based on the modified overall mechanical performance model, and the deformation deviation value is obtained by comparing it with the actual deformation parameters. The calculation weight of the cable quality coefficient is adjusted based on the deformation deviation value and the surface parameter change rate.

[0042] The cable quality change curve is compared with the standard quality curve. The cable quality grade is determined by combining the curve similarity, cable quality coefficient, and the influence coefficient of defects on local mechanical properties, and an inspection report is generated.

[0043] Compared with the prior art, the present invention has the following advantages:

[0044] This invention, by setting up multiple load units, can apply tensile force to the cable from different load-bearing directions and different load-bearing surfaces, while simultaneously covering the load-bearing surface (first detection surface) and the non-load-bearing surface (second detection surface). This breaks through the limitations of traditional detection methods that only target a single force direction or a local surface, and comprehensively captures the quality characteristics of the cable under complex stress conditions.

[0045] This invention, combining the structural characteristics of cable layers, defines the load-bearing parts that are independently or jointly stressed through a first processing module, and uses an interference source to accurately divide the stress-bearing body, enabling targeted mechanical analysis of single-layer and composite-layer structures. This solves the problem of traditional testing neglecting the differences in layered structures, leading to distorted overall mechanical performance assessments, and makes stress and strain distribution data more closely match the actual stress state of the cable. By acquiring structured light reflection signals through a first and second optical module, and based on the three-dimensional reconstructed structural model, it identifies the location, size, and shape of surface defects, and correlates them with the basic mechanical performance data of the corresponding load-bearing parts, quantifying the influence coefficient of defects on local mechanical performance. This overcomes the defect of separating surface defects from mechanical performance assessment in traditional testing.

[0046] The load adjustment module dynamically adjusts the tensile parameters based on the mass coefficient and deformation deviation value, generates multiple sets of load test data and constructs a mass change curve. By comparing with the standard curve, it effectively reflects the quality stability of the cable under different load conditions, solving the problem that traditional fixed load testing cannot simulate actual complex stress scenarios, and making the quality assessment more in line with actual application needs.

[0047] From acquiring basic cable parameters and setting load and optical parameters to establishing and correcting mechanical models, determining quality levels, and generating reports, a complete automated testing process is formed. By integrating data from multiple modules through a central processor, the testing efficiency and evaluation accuracy are significantly improved, providing a scientific and comprehensive quantitative basis for cable quality control.

A mechanical performance model is established based on the basic mechanical performance data, and then corrected by combining the influence coefficient of defects on local mechanical performance to obtain the overall mechanical performance model of the cable. The theoretical deformation parameters are calculated based on the modified overall mechanical performance model, and the deformation deviation value is obtained by comparing it with the actual deformation parameters. The calculation weight of the cable quality coefficient is adjusted based on the deformation deviation value and the surface parameter change rate. Adjust the tensile parameters of the load unit according to the cable quality coefficient and deformation deviation value, obtain multiple sets of load test data and generate cable quality change curves; The cable quality change curve is compared with the standard quality curve. The cable quality grade is determined by combining the curve similarity, cable quality coefficient, and the influence coefficient of defects on local mechanical properties, and an inspection report is generated.
