摘　　要：本文结合虚拟仪器技术和近红外光谱分析技术搭建一个快速无损检测整粒小麦成分含量的系统。此系统以890nm和940nm两个波长的LED以及14个窄带干涉滤光片为光源电路部分;以检测器和运放为信号转换和调理部分;以NI公司的数据采集卡PCI-6040E为数据采集部分;数据的采集、显示、分析、保存均集成在同一个虚拟仪器面板上;此系统具有成本低廉、开发时间短、功能灵活、易扩展和维护且可进行现场无损检测等优点。The paper designed a system of measuring the protein content of integrity wheat quickly and non-destructively using the virtual instrument technology and NIRS technology. In this system, the 890nm and 940nm NIR LED and fourteen interference filters were act as the light source, detector and operational amplifier were act as the signal conversion and condition circuit, NI-DAQ card PCI-6040E was act as digital acquisition. The acquisition, display, analysis and save of data were all integrated on a panel. And...
