| Summary: | According to the characteristics of weak expandability, complex networking, poor communication ability and high running cost of existing system, a new agricultural water-saving irrigation system is design based on data transmission unit (DTU), wireless radio frequency (RF) module and microcontroller, the application of RF module in the acquisition terminal improves the expandability, data of soil moisture are collected by relay station, and then transmitted to the monitoring center by the DTU using GPRS network. Monitoring center devises water-saving irrigation schemes according to the analysis of soil moisture data collected from acquisition terminal, then it send control commands to adjust the irrigation volume of each terminal. The system completes data collection, transmission and analysis, realizes water-saving control. Experimental results show that this system can collect real-time data of soil moisture, maintain the value needed for crop growth. It lays a solid foundation for the further development of precision irrigation system. The whole system powered by solar energy, has the characteristics of simple structure, easy to expand, large volume data transmission, low cost, energy saving and environmental protection, has the value of usage and popularization. |
