摘　　要：为满足农户和精细农业联合收割机等市场对获取农田基本信息的技术需求,利用GPS的定位功能和部分传感器,研制了农田面积快速测量仪。其由低成本的GPS模块、单片机、键盘、LCD显示、U盘读写、通讯接口及温湿度传感器等模块组成。同时,给出了GPS定位信息的获取技术、多边形农田面积的计算方法和测量仪软硬件的设计原理等,并做出了一台测量样机。试验结果表明,该测量仪性能稳定、运算快速,面积等各参数测量误差不大,可满足农田测量精度要求。In order to meet the requirements of the market, including the farmer and the combined harvester, to obtain the basic information through the GPS positioning function and some sensors, this study has developed a new instrument to measure field area. The instrument mainly consists of a low-cost GPS module, a micro-controller, a keyboard, a LCD display, a U disk module, interface modules and humidity sensors. It has provided the technology of GPS positioning function, the calculation method of measuring the polygon farmland, the design principle of hardware and software of the instrument are also introduced. Finally the measuring model machine has been made. The results of the tests indicate that the instrument is stable, operation rapidly and has small measurement errors, which could better to satisfy the accuracy requirements of the agriculture combined harvesters.
