Design of core fault detection system for steel cord conveyer belt

A machine vision method based on the virtual instrument has been put forward for the problem of joint elongation and rust in the steel core of mine conveyer belt.A set of fault detection system has been established for steel cores of the conveyer belt.The images of the steel core have been acquired and preprocessed and the faults have been discriminated.The joint＇s length and corrosion area have been measured.The BP neural network of automatic image classification for steel core faults has been achieved.An adaptive learning rate algorithm is proposed.Elaborate targets are recognized and measured accurately and promptly using machine vision.The measurements of steel core joint length and corrosion area are made.The detection system can detect rapidly and accurately the joint elongation and corrosion faults of the steel core,which provides security guarantee for coal transportation and production.
