基于虚拟仪器的近红外整粒小麦成分的测量系统

Measuring system of NIR wheat component based on virtual instrument

结合虚拟仪器技术和近红外光谱分析技术搭建了一种快速无损检测整粒小麦成分含量的系统。详细介绍了该系统的硬件和软件设计,并扫描了40个已知粗蛋白化学值的整粒小麦样品的光谱图,建立了光谱数据与整粒小麦粗蛋白含量间的关系模型来检验此系统的性能。结果表明此系统可以用于现场对整粒小麦进行快速无损检测。

A system was designed for measuring the protein content of integrity wheat quickly and non-destructively using the virtual instrument technology and near-infrared spectroscopy （NIRS） technology. The hardware and software designing were introduced, and 40 NIR spectrums of integrated wheat with known crude protein content were scanned in the experiment; the model with the NIR spectrums and integrity wheat component was established to verify the capability of this system. The results show that this system can be used in the situation of quick and nondestructive detection to integrated wheat.
