苹果无损糖度检测系统的设计及试验

Design and Experiment of Non-Destructive Sugar Content Measurement System for Apples

本文介绍了一款利用智能手机进行苹果无损糖度检测的系统,由收发光器件将光源中有效照射至待测苹果上并反射回来的光进行汇聚传输至光谱仪进行成像,将光谱信息转换成数字信号,传递至既定的数字模型进行分析处理,最终测量数值在手机App上进行显示,从而实现对苹果糖度的无损测量。经过实测对比,该系统检测误差在0.80%~26.32%。

This paper introduces a system for non-destructive sugar measurement of apples using smart phones.The light effectively irradiated by the light source on the apples to be measured and reflected by the light receiving and emitting device is concentrated and transmitted to the spectrometer for imaging.The spectral information is converted into digital signals and transmitted to the established digital model for analysis and processing.Finally,the measured values are displayed on the mobile phone App,so as to achieve non-destructive measurement of apple sugar.Through actual measurement and comparison,the detection error of the system is between 0.80%and 26.32%.
