Research On Tobacco Sorter About Impurities Removed From Tobacco And Status Monitoring Based On CCD Image

The intelligent inspection system of tobacco is a special device, which is used to eliminate the impurity from the raw tobacco. It is a complicated system relating to photo-electricity, optics, computer, electronics and mechanism, etc. Its use enhances greatly the level of automation and debases the stress of work. It can ensure the quality of final products. This system can be applied widely in pharmacy industry, foodstuff industry, etc. with little revised.The system grabs tobacco digital image from the product line with the line scan CCD camera based on machine vision. And the digital image is transmitted to the image-processing unit. Computer controls the high-speed pneumatic valve by the process result, using the high-pressure airflow blow the impurity and the musty tobacco leaf. And the system function is accomplished.This paper emphasizes on the study and design on image manipulation and fault diagnosis of the intelligent inspection system of tobacco. Firstly,it discusses the value and perspective of the system,and gives the scheme of the design.Secondly, the illumination designing,the image data grabbing and manipulation scheme are presented. And fault diagnosis of the view scope illumination, arithmetic of identify impurity are presented based on these basement.And then,on the base of the C/S model structure and VPN, introduce the center control and remote control, and make remote fault diagnosis and remote maintenance possible.
