Study on the Intelligent Water Saving System Based on the WSN and GPRS

Depend on the Analysis on the history,present status of the water saving irrigation technology;we put forward intelligent water saving irrigation system based on the wireless sensor network and GPRS network,which can transfer the crop water requirement information to the automatic control system.In this paper,Remote and wireless transmit of data,spot control and the technique of monitoring-forecasting of soil moisture regime are realized.According to the fact of irrigation district and the characteristic of wireless sensor,a feasible wireless sensor network system used in farmland irrigation area is designed.The system solves the problems of network structure,node localization,routing and energy supervision.Control software of spot computer adopts fuzzy control theory and the design of software among the client computers,center computer and the computer on the spot are researched hardly.Experiment shows that the system is reliable and suitable for those testing situation in convenient for cable connection.
