| 摘 要： | 在分析国内外近红外检测技术及仪器现状的基础上,开发了一种由三波长的近红外发光单元、信号传感检测单元、单片机数据处理分析单元、工作软件等组成的谷物蛋白质近红外检测仪。选取35个样品进行实验,数据表明,样品吸光度与蛋白质含量存在明显的非线性。因为多元线性回归模型和BP神经网络模型预测值与检验集样品实测值相关系数分别为0.6491和0.9372,平均相对误差分别为9.66%和3.46%,所以该仪器选用BP神经网络模型作为校正模型,能够满足谷物蛋白质检测的需求,而且该仪器具有结构简单、体积小、操作方便、无移动部件等特点。

| Abstract: | The current state of NIR spectrology and NIR instruments was analysed.Then a NIR detector for grain protein content was developed.This detector is composed of a radiation source unit with three single wavelength LEDs,a signal detecting unit,SCM data processing unit and software.It is characterized by simple structure,small volume and easy to use with no mobile parts.Using this detector,measurements were conducted on 35 selected samples,which show obviously non-linear relationship between the absorbency and ... |
