2013 ( )( ) () PLC IO PLC I Abstract Color sorting system has been widely used for discriminant surface quality ( discriminant surface quality refers to the use of light reflection characteristics, in accordance with the skin color differences separating, according to with or without appearance damage sorting ) discrimination and internal quality ( discriminant internal quality refers to the use of light transmission properties, separation, in accordance with the maturity difference according to the internal damage between sorting in accordance with the internal quality difference, sorting, etc.). Use color sorter replaces manual election, exclude the interference of human factors, not only improves the production efficiency ( such as sorting accuracy, consistency, and reduces the production cost ). From the economics point of view or from the ecology viewpoint, application of color sorter is extremely beneficial and effective. Then the mechanism design of control system by PLC. The system was designed, the principle, IO
