中文摘要：

为解决传统虚拟仪器技术可重构性比较弱的问题,以传统虚拟仪器技术为基础,结合基于构件技术的软件开发理论,提出了一种基于软件构件化技术的可重构虚拟仪器设计方法.结合工业应用问题,采用VC＋＋及OpenGL技术构建了虚拟信号发生器和频谱分析仪,实现了虚拟仪器系统的在线重构,提高了系统构建的灵活性.

英文摘要：

A reconfigurable virtual instrument software design method is proposed,which can resolve the reconfigurability scalability of traditional virtual instrument.Based on the original virtual instrument technology research,component-based software development technologies and industrial application,this paper designes the software of the signal generator and spectrum analyzer.Thus online reconstruction and flexibility of the virtual instrument system is realized.
