Design And Implementation Of Environmental Monitoring System Of Greenhouse Based On WSN Technology

Greenhouse is planting crops in the controlled environment of modern agricultu ral production, monitoring, and control unit of agricultural production growth enviro nment to crops through greenhouse technology, realize the efficient production of ag ricultural crops. Compared to the greenhouse technology development in the greenh ouse, in China there is a serious shortage in the scientific and technological innovat ion and production technology, especially in the environmental monitoring and contr ol and other key links, because the agricultural equipment behind or inadequate, res ulting in the low level of production automation, the lack of suitable for China’s ag ricultural products.In view of the above problems, this paper proposes a wireless sensor network environmental monitoring system, the system through the environmental temperature, WSN technology of greenhouse environment humidity, soil temperature, soil moistu re, carbon dioxide, light intensity and greenhouse physicochemical indexes were mo nitored in real time, with acquisition, automatic alarm, trend prediction and statistica 1 query functions. According to the user the use effect, the system can be 7*24 ho urs monitoring of greenhouse environment, physical and chemical index error rate o f<1% environment, the environment factor forecast early recognition algorithm of a griculture risk, reduce the risk of agricultural planting.In the process of design and implementation of this thesis, relates to the power electronic technology, computer technology, information and network control technolog y, electromechanical integration technology, the design of the wireless sensor network protocols a tree structure, forecast the trend of the change of environment factor by d ata fitting technique, developed a support communication technology of wireless senso r network 2.4GHz environmental physicochemical index monitoring equipment.
