摘要
采用最新集成芯片和软件设计 ,研制出以近红外LED为光源的整粒小麦成分快速分析的仪器 ,为小麦成分的现场检测提供了一个经济、快捷的便携式设备。该测量仪由近红外LED光源、窄带干涉滤光片、菲涅尔透镜、硅光电池检测器、单片机系统及校准模型等组成。与其他近红外仪器相比 ,该测量仪具有体积小、结构简单、低功耗、抗震动等特点。同时介绍了该测量仪的硬件设计 ,软件设计 ,对小麦蛋白质的建模和预测应用实例等。
A integrity wheat component quickly measuring apparatus which based on NIR LED was developed, by using new chip and designing software. While providing a lower cost apparatus, it also provides quick answer speed and smaller size for fieldwork of wheat's components measuring. The apparatus is made up of NIR LED, interference filter, lens, Si photronic detector, microprocessor system and calibration model. Compared with other instrument, the apparatus has many advantages, such as compact space, simple structure, low power waste, and anti-shake. This paper introduces the design of the apparatus, and predicts the concentration of wheat protein. The apparatus can realize non-damage measurement of wheat components' concentration on fieldwork.
