Photoelectric detection device of color charge coupled device (CCD) color sorter

Abstract

The invention discloses a photoelectric detection device of a color charge coupled device (CCD) color sorter. The photoelectric detection device comprises an image acquisition module, which is utilized for collecting simulated images of coarse cereals needing to be detected, transforming the simulated images into the coarse cereal digital images and transmitting the coarse cereal digital images to a digital signal processor (DSP) module, the DSP module, which has the interaction with the image acquisition module, carries out pretreatment on the coarse cereal digital images transmitted by the image acquisition module, respectively carries out integrity detection, mildewing detection, germination detection and granule detection of the coarse cereal digital images according to a preset detection rule, and transmits detection results to an upper computer orderly through a synchronous serial interface and an interface board, wherein the upper computer selects a coarse cereal discharge channel according to the detection results, and a power supply and clock module, which is utilized for supplying electrical power and a working clock to the image acquisition module and the DSP module. The photoelectric detection device can respectively carry out integrity detection, mildewing detection, germination detection and granule detection of coarse cereals and can select a coarse cereal discharge channel according to detection results, and thus realizing multiple grading screening and improving a coarse cereal detection identification capability.

Description

technical field [0001] The invention relates to a miscellaneous grain color sorter, in particular to a photoelectric detection device of a color CCD color sorter. Background technique [0002] With the in-depth development of my country's reform and opening up situation, the overall national strength is getting stronger and stronger, the people are getting richer, and the living standards of the people are getting higher and higher. People pay more and more attention to the accuracy and hygiene of food, and the raw materials of processed food Requirements for precision and purity are also becoming more stringent. The accuracy of many high-grade food raw materials is significantly improved after color sorting, and their value is doubled. Color sorters came into being in my country. First, they were rapidly developed in the rice industry, and then developed in the fields of seeds, oil, and fruits. [0003] Existing photoelectric color sorters for miscellaneous grains generally...
