Study on Field Information Fast Collection System

A Palm-sized Personal Computer (PPC) based field information fast collection system was designed for the purpose of acquiring and analyzing field information effectively. Compared with desktop PC, the operation system of this system (Windows CE) is greatly different in many aspects. So some key technologies was analyzed and debated. They are geographic information system (GIS), spatial accessing methods, database technology on windows CE, sampling control plan, a special buffer analysis method and etc. Considering the particularity of farms, an object-oriented farm model was put forward. As a real-time system, the system can be used with global positioning system (GPS) and kinds of sensors to acquire and analyze field information instantly. The research and development of the system provided key technology for the development of precision farming field information fast collection and real-time processing equipment.
