摘    要:为降低成本并提高获取农田基本信息的效率,设计了一种基于GPS-OEM模块,由GPS-OEM模块、单片机、键盘、LCD显示、U盘读写模块及通讯接口等组成的采集系统。试验结果表明,该系统能够进行农田位置的定位和地块长度及面积的测量;长度测量的最大相对平均误差和相对均方差分别为0.79%和3.29%,面积测量的最大相对平均误差和相对均方差分别为2.03%和11.1%,并且面积越大,测量精度越高。理论分析表明,进一步减少测量的偶然误差,将会使测量精度有更大的提高。

Abstract:The basic information of field plays an important role in precision agriculture.In order to lower the cost,and improve the efficiency of getting the basic information of field,the acquiring system based on the GPS-OEM module was designed.The system mainly consisted of a low-cost GPS-OEM module,a micro-controller,keyboard,LCD display,U-disk module and communication interface.The experiments showed that the system could measure position,length and area of field.The mean relative error and mean standard deviation of length and area experiment were 0.79%,3.29%,2.03%and 11.1%.And the bigger the area was,the higher measuring accuracy was.Analyses indicated that decreasing the casual error could improve the measuring accuracy.
Keywords:basic information of field  acquiring system  GPS-OEM module  precision agriculture
