摘　　要：针对基于硅光电池的色选系统色选大米的快速性和高准确率要求,采用双因素方差分析方法分析了光源类型、大米下落速度、反光板角度等因素对硅光电池接收系统响应的影响.结果表明,光源类型对硅光电池接收系统响应具有显著影响,下落速度和反光板角度影响不显著.根据实验得到了蓝光光源、3.m/s速度、3.6°反光板角度的实验参数.运用示波器对波形进行分析,证明了该方法的实用性.To meet the fast and precision requirement of color sorter,two-way ANOVA method was used to analyze the effect of light source, speed of rice and angel of reflector panel to voltage output of silicon photocell. Results show that light source has significant effects on voltage output, while speed of rice and angel of reflector panel have not significant effects on voltage output. Blue light,3m/s and 3.6° were selected as experimental condition. And the output waveform was analyzed by means of oscilloscope to prove the feasibility of the solution.
