Excogitation And Implementation Of Monitor System For The Greenhouse’s Host Machine

China is now during the new stage that traditional agriculture change to modern agriculture, and greenhouse environment control is one of the most important landmarks of agricultural modernization. It has become an important issue for scientists who working in agricultural industry that how to control greenhouse crops up in the best environment. In view of the existing greenhouse’s shortcoming in software and hardware, this paper studied and developed a intelligent monitoring greenhouse system, which suit to Chinese national conditions.(1)Studied the important environmental parameters in greenhouse, such as temperature, humidity, light, and analyzed the methods of regulatory control.(2)After research the structures of greenhouse control systems which already exist, a new structure for greenhouse monitoring system was given. The structure based on host and slave computer were proposed in this paper, the functional modules of this structure independent design but can cooperate in harmony, this design is suitable for small-sale greenhouse.(3)Studied of greenhouse host system implement scheme, designed and implemented the PC systems and database management systems, the results showed that the system has powerful functions, which can achieve greenhouse data management and statistical data analysis.
