Abstract

The invention discloses a full-automatic cable multi-layer parameter intelligent detecting method and device. The thickness of a cable insulation piece is automatically measured. The method comprisesthe steps of obtaining a cable slice image; automatically selecting a proper independent light source and an industrial camera set; automatically performing micro regulation on the cable slice position; performing preprocessing; extracting an image communication region and performing multi-layer contour detection; selecting points and determining multi-layer measuring points; calculating related parameters, and generating a report. According to the full-automatic cable multi-layer parameter intelligent detecting method and device, the automatic degree is high, the detection efficiency and precision are high, and meanwhile the labor intensity of detection workers is greatly lowered.

Description

technical field [0001] The invention belongs to the technical field of precision measurement, and in particular relates to a method and device for intelligently detecting parameters of each layer of a fully automatic cable. Background technique [0002] The insulation structure of general cables is mainly composed of conductor shielding layer, insulating layer, insulating shielding layer and semiconductor shielding layer. If the insulation thickness of the cable is lower than the standard or the eccentricity exceeds the standard, it will seriously affect the performance of the cable, and even endanger the safety of the power grid, resulting in property loss and casualties. [0003] At present, there are many manual operations in the method of measuring the thickness of cable insulation. Manually fix the cable slice on the pressing plate, manually adjust the position of the cable slice, and then determine the thinnest thickness of the cable slice according to the scale of the...
