基于单片机的温室大棚自动卷帘控制器设计

Design of controller for greenhouse met roller based on MCU

大棚卷帘机是日光温室的重要农业机械。针对大棚卷帘机在使用中存在耗费工时、影响光照时间的问题,设计了基于AT89S52单片机的大棚自动卷帘控制器。自动卷帘控制器根据温度和光照条件控制卷帘电动机的运行,可实现卷帘机的自动卷帘和放帘。实验结果表明,该控制器可增加作物的6.97%日均光照时间,日节约工时0.3h,正常工作率为99.15%。

Greenhouse curtain rolling machine is an important agricultural machinery in greenhouse. According to the problem of time-consuming and shorten the time of illumination time in use, the greenhouse curtain rolling machine automatic controller based on AT89S52 MCU was designed. Automatic rolling curtain controller can control the motor automatic rolling and put the curtain based on the temperature and illumination condition. The experimental results show that the automatic rolling curtain controller can be increased by 6.97% average daily light irradiation time on crops, saving hours of work by 0.3h and normal operating rate is 99.15%.
