Design of Embedded Cropland Data Acquisition and Processing System Based On Xscale and WinCE

In precision agriculture technology system, cropland data acquisition acts as the foundation as well as the weakness of our countrypsilas research on this field. In this dissertation, according to the present actual demands, an embedded cropland data acquisition and processing system is designed. The system is supposed to achieve many tasks such as agricultural sensors data acquisition, GPS information acquisition and navigation. During the process of design, factors such as performance, cost, and expansibility are all taken into account. The hardware is based on a 32-bit embedded microprocessor with high performance but low power consumption - Intel Xscale PXA270, while the real-time operating system is Windows CE 5.0. This design has very important practical significance to speed up the process of agricultural modernization in China.
