摘要
以大米分选过程为实例，设计了一种根据亮度信号大小的变化对生产过程进行自动控制的系统。该系统利用数字信号处理专用芯片ＴＭＳ３２０Ｃ３１，采用恒虚警算法，实现自动增益实时控制。系统界面友好，操作简便，能同时完成多通道材料自动分选。
Based on an explanation of rice sorting,a sorting system which can control the process automatically according to varying light signals is designed.In this system,AGC is controlled automatically on real time basis with the aid of special Digital Signal Process Chip TMS320C31 and CAFF algorithm. This system featuring with friendly interface and easy operation can implement multi channel sorting automatically with high precision.
