FARM AREA-MEASURE SYSTEM DEVELOPMENT BASED ARM7 GPS

摘要

Pricing system of farm area measurement for combine was developed based on the ARM7 & GPS. In this paper, the system hardware system architecture was designed, including the design of COM port, GPS accessing circuit design. The corresponding driver program was prepared in the C environment. The experimental result shows that the system can record information in real-time, including working time, geographical coordinates, the operating area and cost, and the device was suit to irregular farmland. And it can provide the basis for real-time calculation of farmland area and billing.
