Study of mobile farmland information monitoring terminal based wireless data transmission technology

Real-time monitoring system of farmland information is the foundation to achieve ldquoprecision agriculturerdquo. the digital collection device for dynamic monitoring of agriculture resources and information dissemination process is studied in this paper. A novel embedded mobile information collection terminal is proposed based on wireless data transmission to achieve the functions of automatic data collection, transmission and the real-time promulgation. The terminal includes a humiture sensor, a module of data processing based on ARM and DSP, a GPS system, and a data link. The whole structure of system is given; The key technologies of system design and development are introduced in detail. The experimental results show that the system is reasonable and stable, data processing is nimble and convenience and so on, suiting for the inconvenience connection agricultural test situation.
