摘要
本文设计了一种用于日光温室的光周期控制器 ,解决了日光温室自动化光照的问题。该设计采用数字电路 ,光电传感器 ,电光源 ,实现了对白天光照接续的时间和晚间增补光照的时间的自动。
A photoperiod controller applied to a heliogreenhouse was designed in this paper. It solved the problem how automatically controlling photoperiod in a heliogreenhouse. With digital circuit, photoelectric transducer and electric light source, the controller can automatically and accurately controls the time for continuing illumination at day and the time for supplementing illumination at night.
