Cable dent generation and detection system and method

Abstract

The invention belongs to the field of cable dent depth detection, and provides a cable dent generation and detection system and method. The system can generate a regular cable sample dent and is capable of automatically, rapidly and precisely detecting the cable sample dent. A dent generating mechanism generates an axially symmetrical dent with a horizontal bottom. A driver drives a laser range finder to move to collect the thickness data of a generated dent of a cable sample and the thickness data of non-pressed positions; the thickness data is sent to a processor and processed by the processor to measure the dent depth; automatic detection is realized, non-contact nondestructive detection is realized, the detection cost is reduced, the efficiency is improved, moreover, the precision of the detection result is high, and the detection result is easy to store and count.

Description

technical field [0001] The invention belongs to the field of automatic detection of the depth of cable dents, in particular to a system and method for generating and detecting cable dents. Background technique [0002] In the era of electrical informationization, cables are closely related to social life and production. Therefore, the safety performance of cables has always been a concern of people. The safety performance of cables includes not only flame retardant performance, but also insulation protection performance. Among them, the dent depth of the cable is an important technical index to measure the insulation protection performance of the cable. The dent depth of the cable generally refers to the distance between the concave surface of the dent of the cable sample and the upper surface of the unpressurized part of the cable sample after the cable is subjected to external mechanical pressure to produce a dent. [0003] Usually, those skilled in the art measure the d...
