Development and implementation of field information management system based on telecommunications

Remote intelligent management meet the needs of precision agriculture development. Field Information Management System was designed and realized in accordance with the thinking of software engineering. As an important component of Mobile Field Information Intelligent Service System, Field Information Management System was the core of field information intelligent management. Field Information Management System received the real－time field information from the wireless mobile terminals (that is field PDA) through GPRS, and stored them into the field information database. The field information was visualized, analyzed, and processed according to the field information process model, and provided support for the decision－making in field variable control.?According to the primary functions of Field Information Management System, the system was divided into 4 modules, which were the map management module, the mobile terminals management module, the data management module and the system management module. Field information is real－time collected, transmitted, processed, and visualized in Field Information Management System, providing comprehensive decision information and technical support for users.
