摘　　要：为了适应在野外环境对植物叶面的曲线长度和轮廓面积等数据的快速采集和查询,设计了一种基于GPS定位功能的嵌入式植物叶面长度面积求算仪。此系统采用GPS卫星定位技术,由SiRFstar III型GPS接收器接收定位信号,采用触摸屏输入技术,由ARM微控制芯片LPC2114完成植物页面长度和面积的采集与计算,实时存储地理位置信息,并对相关数据进行分析,由液晶显示屏AT070TN83显示输出。此系统采用嵌入式控制技术,可移植性高,操作界面简单、体积小、在记录标本长度面积的同时记录了此标本的地理位置,为科研工作者提供了可靠的数据信息与结果分析。实验结果表明本设计方案具有速度快、精度高、成本低等优点。In order to quickly capture and inquire plant leaf＇ s curve length and profile area etc. in field work, a leaf area and edge length measurement embedded system with GPS positioning function has been designed. The analyzer receives positioning signal by SiRFstar III GPS receiver, inputs capture and inquire instructions through touch screen, accomplishes the acquisition and calculation of plant leaf＇ s curve length and profile area by adopting ARM micro-controller chip LPC2114, records and stores geographical information of the plant in real-time, analyzes the obtained related-data and displays the data on the liquid crystal display （AT070TN83）. Moreover, the embedded control technology offers good portability. This system provides credible information of leaf area and edge length as well as location information for science researchers with simply operation and small volume. The validity and effectiveness are verified through comprehensive experiments.
