摘　　要：基于虚拟仪器技术开发了精细农业空间信息及属性信息的快速采集与实时处理系统.该系统由传感器、全球定位系统(GPS)接收机、数据采集(DAQ)卡与计算机等组成.软件平台的设计采用LabVIEW.利用多种传感器采集农田的属性信息,输出信号经数据采集卡传输到计算机;利用全球定位系统获取空间信息,经由串行端口接入计算机,由软件平台分析和处理.结果表明,该系统可实时同步地测量和分析农田的多源信息,并利用数据库系统管理测量数据,测量项目易于扩充,为精细农业田间信息快速采集和处理设备的开发以及与地理信息系统(GIS)、管理信息系统(MIS)的联结奠定了基础.A virtual instrument system capable of rapid acquisition and processing of farm field spatial information and property information was developed. This measurement system consisted of sensors, global position system （GPS） receiver, data acquisition （DAQ） card and computer. The software was developed by graphical programming language LabVIEW. The property information was acquired using various sensors, with the sensors output signal transmitted to computer via DAQ card. The spatial information was acquired using GPS receiver and its signal transmitted to computer via serial port. All information acquired was analyzed and processed on the system software. The results show that this system can in real-time and synchronously measure and analyze farm field information, and that the database can effectively manage the test data. This work provides key technology for the development of equipment for rapid information acquisition and processing and the combination of geographic information system （GIS） and management information system （MIS） in precision farming.
