Abstract: Intelligent greenhouse can promote development of modern agriculture, realize high quality and high yield of crops, and bring great economic benefits． According to climate conditions in Northwest, a set of intelligent control system for diversified environment of solar greenhouse was designed． Greenhouse regulation was divided into six stages in a year according to optimal energy conservation． Modern detection technology was uses to collect greenhouse environmental temperature, environmental humidity, soil humidity, carbon dioxide concentration and illumination parameters under different working modes． Programmable control technology was used to realize data processing of various parameters and action control of film rolling, wet curtain fan and other actuators． Kingview monitoring software was used to realize monitoring and manual control of greenhouse environmental parameters． Operation results showed that regulation system operated stably and basically met control requirements．
