鉴于单片机的农田界限 GPS 坐标检测与显示系统设计
摘 要
GPS(Global Positioning System>即全世界定位系统,是一种利用卫星支持的无线电导
航系统。目前, GPS技术宽泛应用于工业、医疗、军事和生活等很多领域,在农业,特
别是精美农业领域, GPS技术也愈来愈多地被运用。在精美农业研究中,农田界限坐标
和农田面积是农田信息中必不行少的数据,农田面积的大小决定了农业生产时种子、肥
料的用量,也是机械作业方面需要认识的数据。所以采纳 GPS 收集农田界限坐标信
息,对实现农业劳作精美化等有特别重要的现实意义。
目前,有些设计能够实现农田界限 GPS 坐标监测及面积计算,但设备价钱较高是
其最大的弊端。在实质农田界限坐标监测中,要求系统拥有稳固性和便携性,所以设计
一种便携式的农田 GPS 坐标监测与显示系统很存心义。本文提出一种鉴于 GPS 技术的
农田界限信息收集与面积计算的解决方案,该方案鉴于单片机和 GPS 开发板来设计
GPS信息收集系统。该系统采纳加强型单片机 STC12LE5A60S2 和 u-blox 的 GPS 开发板
来收集农田坐标信息,经过 TFT 屏进行显示,并经过 PC 机进行面积计算。
过去对土地坐标和面积的丈量常采纳人工操作的方法达成,该法拥有耗时费工、工
作效率低下的显然缺点。该系统利用 GPS 技术设计了便携式的农田界限坐标监测设
备,经过单片机对 GPS 报文信息进行办理,可及时获取和显示农田界限坐标信息,并
对农田面积进行计算,该系统拥有系统构成简单,保护方便,运转花费低等长处,能够
实现靠谱的数据收集和办理,能够应用于农田界限坐标信息的监测。

(College of Engineering, South China Agricultural University, Guangzhou 510642, China> Abstract:Global Positioning System (GPS>, is a use of radio navigation System supported by satellite. At present, GPS technology is widely used in industrial, medical, military and life and many other fields, in agriculture, especially in precision farming areas, the GPS technology is also increasingly being used. In the study of precision agriculture, farmland boundary coordinates, and area of farmland is an essential data in farmland information, determines the amount of seed, fertilizer and agricultural production, is also the mechanical operations need to understand the data. Therefore, using GPS to collecte coordinate information of farmland boundaries, has a very important practical significance to realize the agricultural work fine.
At present, some design can realize farmland border monitoring GPS coordinates, and area calculation, but the high price of the equipment is its biggest drawback. In actual fieldboundary coordinates monitoring system has stability and portability, so design of a portable GPS coordinates farmland mo
