Application and Research of Agricultural Irrigation Fertilization Intelligent Control System Based on GPRS DTU

This paper developed a intelligent control system that can fertigate according to crops’ requirements. At first, the overall composition of this system was expounded. It used kingview 6.55 and measurement and control center software as the development platform, and HORNER OCS as the core controller, and it constructed agricultural fertigation control system. The communication module is GPRS DTU, and the system pressure adjustment was achieved by frequency converter. Secondly, related technology such as communication protocol, port mapping, dynamic DNS and peanut shells software was introduced. The system software development, database design and public based on the Internet was completed. The system test results show that the system was fully function, stable running, and met actual demand of water and fertilizer management in agriculture.
