Research And Design For Intelligent Control System Of The Environment Of The Green House

Factorized agriculture is an important aspect and part of Agricultural Modernization, and environment intelligent control of green house is the key technology,which plays an important role in green house agriculture. But, the research of environment intelligent control of the green house does not develop well in our country, especially the research of cooperation of agriculture expert system and automatic control technology. Obviously, it is important to develop the adaptive intelligent control system of the green house. The technologies, such as agricultural meteorology, plant physiology, crop cultivation, oil characters, sensor measurement, automatic control, expert system, fuzzy control, etc., are introduced in this paper. Based on these technologies, a practical and advanced green house intelligent control system is put forward and realized in this paper, the system have such functions. First, according to grow circle and requires of the crop, the system can automatically control the temperature, humidity of the air, quantity of illumination, moisture of the oil, and CO2 of the air. Second, on the basis of practical environment, control parameters of the system can be modified by users. Third, for the sake of security, alarm function has been provided by the intelligent control system, once problems and errors are taken place, the system automatically alarms. As results of preliminary experiments, the system is workable and reasonable.
