摘　　要：目前,在黑龙江地区的温室大棚内种植反季节或当下蔬菜时,补光时间和补光强度全部靠人员经验,因此无法达到精准控制。本文针对这一问题设计一个基于AVR单片机的温室大棚LED智能补光系统。该系统基于ATmega16L单片机,利用光敏电阻阻值变化引起电路电流的变化,测出大棚内光照的强度,设定占空比进行间断补光,通过脉宽调制(PWM)控制LED灯光照强度,从而达到实际需要的光饱和点。本文选用蓝光、红光比例1∶8的LED补光灯补光,代替传统的一些补光手段。该系统节能环保、安全性高、稳定性好,在温室大棚智能控制方面具有很好的应用和推广前景。Staff experience is commonly used in planting the anti-season or seasonal vegetables in the greenhouse of Heilongjiang currently,which makes difficulties for precisely controlling the light supplement time and intensity.An LED intelligent light supplement system was designed for greenhouse based on AVR micro controller to solve the problem mentioned above.Based on ATmega16 L SCM,the value changing of photosensitive resistance was used to leading the changing of circuit current,and then the light intensity was measured.After the duty cycle intermittently adding light was set,LED light intensity could be controlled through PWM,thus the actual needs of the light saturation point would be achieved.Blue and red ratio of 1∶8was chosen to add light,replacing some of the traditional means.This system is energy-saving,environmental protecting,high security and good stability,having agood application and promotion prospect in the intelligence control of greenhouse.
