基于XScale和Linux的精准农业农田信息采集系统设计

针对精准农业对农田信息的采集要求,将农田数据采集与嵌入式技术、GPS和GSM通信技术相结合,以XScalePXA270处理器为核心,并辅以CPLD高精度数据采集电路,设计了一种基于XScale处理器和Linux操作系统的嵌入式农田信息采集系统.系统能将采集的农田信息以GSM短消息的形式发送到数据采集中心,解决了野外信息存储的有限性和移动测量的不便性等问题,为农田信息的远程采集提供一种有效的解决方案.

The design of farmland information collecting embedded system based on Xscale and Linux

According to the farmland information collecting requirement of precision agriculture,an embedded farmland data collecting system based on XScale processor and Linux OS is designed.In this system technique of embedded,GPS and GSM communication technique are combined with technique of farmland data acquisition.XScale PXA270 processor,which is the core,is combined with very precision data collecting circuit.The system can send the farmland information collected to the center of data collecting in form of real time GSM short message,so it solves the problems of limitation of information storage and the inconvenience of moving the device here and there in the field.Therefore,it provides an effective approach to collect long-distance farmland information
