随着精准农业的发展,农业种植和农业研究人员需要一种手持式NDVI测量仪,以便对农作物长势进行定量测量。本文讨论了一种手持式NDVI测量仪的完整设计过程,详细论述了设计原理,并给出了详尽的单片机程序、设计电路原理图及PCB图。该NDVI测量仪采用太阳光作为光源,光电探测器采用滤光片和光敏二极管实现,用AT89C51单片机控制。其具有结构简单、成本低、轻便、低功耗的特点。-With the development of precision agriculture and farming, and agricultural researchers need a handheld NDVI measuring instrument, in order to crop growth for quantitative measurement. This paper discusses a handheld meter NDVI the integrity of the design process, discussed in detail the design principles, and gives a detailed SCM procedures, circuit schematics and PCB plans. The NDVI measuring instrument used sunlight as a light source, photodetector using filters and photodiode realized, with AT89C51 control. Its structure is simple, low cost, lightweight, low-power characteristics.

* Hardware architecture: PA0
* 硬件结构: PA0-5对应6个LED数显管的位 ,PC0-7对应各LED数显管的段 ,PB4-7为键盘。
* 软件描述: 上电后,时钟从00.00.00(时/分/秒)自动走时,在走时状态时 , 按PB4(设定
* 键)超过3秒可循环选择调整时间/工作参数 ,接着按PB5以确定选择的操作 ,进入调整操作后 ,
* 按PB5选择欲调整参数,按PB6(增加键)完成调整参数操作 。按PB7,进入时控运行,PB1亮,
* 再按PB7停止时控运行,回显走时。在定时到时,PB0点亮。- * Hardware architecture: PA0-5 corresponds 6 LED numbers to reveal the tube the position, PC0-7 corresponds each LED number to reveal the tube the section, PB4-7 is a keyboard.
* Software description: After on electricity, clock from 00.00.00 (when/a minute/second) is in luck automatically, when is in luck the condition, according to PB4 (hypothesis
