基于红外光谱的梨糖度无损检测系统设计

Design of pear sugar degree non-destructive detection system based on infrared spectrum

为了提升梨在采摘期的品质,文章设计了基于红外光谱的梨糖度无损检测系统,该系统光电探测器采集红外光照射样品梨所产生的漫反射光信号,并将其转换成相应电压值,然后,通过最小二乘法来建立其电压值与梨糖度的相关模型,再与单片机技术结合,就可以实现对梨糖度的无损检测。

In order to improve the quality of pears in the picking period,this paper designs a pear sugar-free detection system based on infrared spectrum,the system photoderactor collects the diffuse light signal generated by infrared light irradiated on the sample pear,and converts it into the corresponding voltage value,and then,by the least-two-multiplication method to establish its voltage value and pear sugar degree of the relevant model,and then by combining with the single-chip machine technology,so as to achieve the non-destructive detection of pear sugar.
