Because the tr aditional agricultural has some characteristics, such as long productive period, many test data, the region dispersion and so on. Ther efore, application of virtual instrumentation in agr icultural appears the high efficiency. This paper firstly introduced the concept, characteristics, ar chitecture, software in virtual instru2 mentation, and bus technique of virtual instrumentation ar e summarized. Then virtual instrumenta2 tion application on agricultur e is introduced. Finally, the trend of application of virtual instrumen2 tation technique in agricultural is prospected. Keywor ds: virtual instrumentation, agricultural, automation, bus technique. 科学的人员专业性要求很强。虚拟仪器可完成对被 0 测样品的采集、分析、判断、显示、存储、打印及数据 虚拟仪器技术( Virtual Instrumentation, 简称 生成。因此缩短农业开发周期, 降低成本, 提高科研 VI) 是随着计算机科学和微电子技术的迅速发展和 效率和测试精度。虚拟仪器技术高性能的模块化硬 普及而逐步发展起来。 986 年, 美国国家仪器公司 件, 结合高效灵活的软件来完成各种测试、测量和自 (National Instruments, 简称NI) 首先提出了/ 虚拟 动化的应用, 因此决定了它在农业领域具有广阔的 [ ] 仪器0 的概念 。近 0 年来, 随着计算机硬件技术 发展前景。 和软件技术的飞速发展。虚拟仪器技术正朝着高性
