Cable section structure measuring and calculating method, system, and device and readable storage medium

Abstract

The invention discloses a cable section structure measuring and calculating method. The cable section structure measuring and calculating method comprises the steps that an image of the cable sectionis obtained; the image is binarization-processed, and a corresponding grayscale image is obtained; according to pixel points of the grayscale image, a calculation section parameter corresponding to the cable section is determined, and the calculation section parameter comprises the insulation layer thickness, the shielding layer thickness and / or the insulation layer eccentricity degree; and the calculation section parameter is converted to an actual section parameter of the cable section by using image conversion coefficient. According to the cable section structure measuring and calculating method, the actual section parameter of cable section can be obtained directly through image processing, cables do not need to be sliced up, therefore, it is not necessary to consider influence of theslicing technology on the measuring and calculating accuracy, the measuring and calculating speed is much higher than the speed of a laboratory measuring and calculating method, the time required forinspection is greatly shortened, all cables can be inspected, and reliability of the whole batch of the cables is improved. The invention further correspondingly discloses a cable section structure measuring and calculating system and device, and a readable storage medium.

Description

technical field [0001] The invention relates to the field of electrical equipment detection, in particular to a method, system, equipment and readable storage medium for measuring and calculating the cross-sectional structure of cables. Background technique [0002] In the power industry, the detection of power cables is an important part of the quality control of power cables, which directly determines the use safety of power cables. occur, affecting the safe and stable operation of the power system. At present, the detection work for power cables is of the nature of random inspection, which cannot accurately reflect the overall quality of the current cable batches to a certain extent. Sampling inspection needs to send samples to the laboratory for testing. The cable samples need to be sliced ​​on site for manual measurement.

At present, the detection work for power cables is of the nature of random inspection, which cannot accurately reflect the overall quality of the current cable batches to a certain extent.

Sampling inspection needs to send samples to the laboratory for testing. The cable samples need to be sliced ​​on site for manual measurement. The slicing process has a great impact on the measurement accuracy; and the laboratory testing process is complicated, and it is impossible to obtain results from on-site testing. The testing cycle Long, affecting the use of the cable
