摘　　要：针对大米色选机中色差信号的特殊需求,设计了以CPLD为核心处理器件的色差信号处理系统,此系统可实现32路色选米道色差信号的同步采集,并输出控制指示灯和气枪。此系统应用于天津光学精密机械研究所的色选机产品,大大提高了色选机产品的性能和用户满意度。For the special needs of the rice color sorter signal, we designed a color signal processing system based on CPLD as its core. This system can collection 32 channels＇ datas and output signals to control lights and solenoid valves. This system applied in the color separator products of Tianjin institute of optics and fine mchanies. Greatly improved the performance of the rice color sorter and user satisfaction.
