PURPOSE: A curtain controlling method for a greenhouse is provided to automatically determine an opening/closing condition of a curtain or the opened degree of the curtain for accurately and effectively controlling the inner environment of the greenhouse.CONSTITUTION: A curtain controlling method for a greenhouse controls a curtain by selecting one function from a temperature control, a light screen control, and a temperature-humidity control. The temperature control includes a step of opening the curtain when the outer temperature detected from an outer temperature sensor is greater than the set value, and a step of closing the curtain when the outer temperature is lower than the set value. The light screen control includes a step of opening the curtain when the present solar radiation is greater than the solar radiation set value. The temperature-humidity control includes a step of closing the curtain when the inner temperature of the greenhouse is lower than the maximum set temperature.COPYRIGHT KIPO 2012본발명은 온실의 커튼제어방법에 관한 것으로, 상기 커튼제어방법은 보온제어, 차광제어 및 온, 습도제어중 어느 하나를 선택하여 제어하는 것으로, 본발명은 온실의 커튼을 환경 요건에 따라 자동으로 개폐여부 및 개폐정도를 결정하여 온실 내부를 정확하고 능률적으로 관리할 수 있는 현저한 효과가 있다.
