Study On The Application Of Distributed Network Control System In Greenhouse

Now how to use automatic control system to control the environment efficiency, and how to manage crop efficiency, are two important tasks in greenhouse research. It has much significance to improve the level of greenhouse manufacturing. In order to control the environment efficiency, Mature and advanced method should be applied in the control-system of greenhouse. This paper fundamentally contributed to the application of distributed networking control system in greenhouse in this paper. A model of system integration of greenhouse control-system was designed by using the fieldbus model for reference in this paper. So a real greenhouse control-system can be accomplished by using this kind of model of system integration. Software of greenhouse management using visual basic was programmed. It can manage greenhouse, communication from computer to singlechip and sample data of greenhouse and so on. Aim At control ventilation of greenhouse, this paper used fuzzy controller to control natural ventilation and mechanical ventilation. A real distributed networking control-system of greenhouse using smart-sensor was devised. This control system has been adopted in Yantai, and works in order.
