摘　　要：通过对当前脱绒棉种分选实现方法的对比,给出了一种双CCD(Charge-coupled device)检测FPGA(Fieldprogrammable gate array)分选实现的方法。通过图像采集模块、数据传输模块和分选模块的分析与设计,结合仿真分析和测试试验,验证了色选机系统效果。其中,图像采集模块采样彩色线阵CCD对脱绒棉种进行成熟度信息采集、黑白线阵CCD对棉种进行完整度信息采集;数据传输模块完成采集数据的传输任务;分选模块依据成熟度和完整度信息对棉种进行判别分析。试验结果表明,色选机系统能够完成对棉种特征信息的采集、数据传输以及分选判别工作,能够满足色选机设计要求。Currently the phenomenon of red-seed （the maturity of cottonseed is low ） exists in the cottonseed processing. Most of the domestic cottonseed processing companies still rely on artificial monitoring to check the red-seed. However, visual inspection of workers exists some problems such as low automation level, large subjective factors and high labor costs. And breakage of cottonseed germination rate and other issues were resulted from the process of cottonseed processing. To solve these problems, a bilateral dual CCD （Charge-coupled device） detection and FPGA （Field-programmable gate array） sorting approach were presented. Through the analysis and design of the image acquisition module, data transmission module and sorting module, and combined with simulation and test trials, the effect of color sorter system was verified. Among them, the image acquisition module can acquire the maturity and integrity information of delinted cottonseeds by using color linear CCD and monochrome linear CCD sampling. Data transmission module is to complete the transfer task of data collection. Sorting module is based on cottonseed maturity and integrity information to sort discriminant delinted cottonseed quality. The results showed that color sorter system can complete the cottonseeds feature information collection, data transmission and sorting discrimination work, which met the color sorter design requirements.
