Design of Intelligent Detection System for Fruit Appearance Quality

Combining advantages of all kinds of fruit grading equipment on the market，the development and design process of an intelligent fruit appearance quality detection system was proposed，which could provide reference for theoretical analysis of intelligent fruit appearance quality detection.On-line fruit grading device was mainly composed of feeding structure，conveying structure，machine vision system，pneumatic sorting structure and electrical control part.Machine vision system included industrial control computer，CCD camera，light source，light box，image acquisition card，trigger，I/O card.The pneumatic part included solenoid valve，air compressor and jet nozzle，and the electrical control part included PLC and solid state relay.
