Study And Research On Tobacco Sorter About The Status Monitoring And Fault Diagnosis

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 the status monitoring 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 status monitoring and fault diagnosis of the system are introduced ,including the function requirement and the resolving program.Thirdly, the illumination designing, the image data grabbing and transmitting scheme, the pneumatic system designing are presented. And the status monitoring and fault diagnosis of the view scope illumination, graphic blur, the pneumatic system are presented based on these basement.And then,the C/S model structure of the LAN implement especially on the protocol of data transfer between server and client is introduced.Finally, the implementing function of the system is given out.
