The Research Of Experimental Platform Of Color Sorter Data Acquisition And Transmission

Every year, China cultivates large amount of grain. But it is difficult for China to export its grain goods, because its low-level of agriculture mechanisation, most parts of China still using manpower as main work force. With the developing of the economy, more and more people pay more attention to the quality of food, including grain. Color Sorters are needed in this situation. Factories are mostly concerned about how to produce next generation color sorters with high speed and high precision.This paper is all about the Research of Experimental Platform of color sorter Data Acquisition and Transmission. It introduces the method to implement the Experimental Platform based on FPGA, LVDS, USB2.0 and VB6.0. It emphasizes on the principle outlines, design difficulties, circuits and programs. And it reports the testing results of the whole system.The system design takes full advantage of the current IC resources to control the timings of FPGA and USB unit efficiently. And settles many core problems such as:high speed data acquisition, high speed parallel to serial conversion, high speed serial to parallel conversion, system synchronization and upload data in a very high speed.Meanwhile, this paper gives a way to design the software, which is the counterpart of the device.Users can receive the data, save the data and show the data finally by using this software. This software can not only provide dynamic data to the research of color sorter arithmetic, but also give a platform for the validate of color sorter arithmetic.After many times of tests, it is proved that this Experimental Platform is feasible and exercisable. It also can give some reference to the design of next generation color sorter.
