Study on precision water-saving irrigation automatic control system by plant physiology

Olympic games in 2008 is not only a world sports event, but also a great opportunity to show our current level of economic development and modern science and technology strength. Precision water-saving irrigation automatic control system by plant physiology this paper described is one of the Olympic games facilities projects, which takes standards of water plant physiologically need and soil water content as the basis. Through the combination of independent research and development of irrigation monitoring controller and wireless data transmission, implement a drip irrigation, sprinkler irrigation, micro-irrigation, and low-pressure pipelines, such as different modes of irrigation automatic control. On this basis, the system monitors by GSM remote wireless communication make all irrigation incidents automatically enter into the database, and generate a variety of reports to the irrigation data for statistical analysis. This paper describes system structure on two aspects of hardware and software design, it is characterized by a flexible mode of operation, reliable control and data transmission, low-cost, remarkable water-saving effect. National road precision water-saving irrigation project´s preliminary trial implies that this new type of precision water-saving irrigation control system with independent intellectual property rights has a higher value for promotion.
