Study On Control System Of Ccd Color Sorter

CCD Color Sorter is according to the material optical character difference, theuse electro-optic sensing technology, the digital image processing technology and themicrocomputer control technology, the color existence difference, the superficialexistence flaw or the internal deterioration's bad material one kind of electro-opticalnon-destructive inspection equipment which sorts from large quantities of materials. Itis distinguished by the color of the product, choose one of the colored granules andother impurities, especially in the unqualified and qualified tablets grain size, densityand the case is very similar, the color sorting become the only method of sorting .CCD Color Sorter can be used on rice, grains, glass, plastics and other complexmaterials, as well as, it can be widely used in tobacco transplant, semiconductor andelectronics industry, and many other areas of machine vision inspection, the marketprospect is broad.Research studies by Pro-Face GP touch screen interface, based on AT89C52microcontroller control board and the PLC for the CCD color sorter to provide acomprehensive control program, the control system let the CCD color sorter systemcoordinated the various components work.CCD Color Sorter control systems need to control components generally include:feeding system, signal detection system, signal processing systems, lighting systems,air-jet valve drive system, cleaning system, color sorting machine control system toachieve human-machine interface through the touch screen parameter adjustmentand switch control to complete the entire CCD Color Sorter control of the system.As the GP touch screen built-in memory link communications protocols, makingAT89C52 microcontroller based memory link communications protocols can beprogrammed GP touch screen communication for non-generic device, this paper givesdetailed solutions to provide the corresponding program flow chart.The final paper describes the application of the control system of the CCD color sorter verify the situation on-site assessment, through experimental results verify thefeasibility and reliability of this system.
