虚拟仪器的结构特点及研究进展

The Structural Features and the Research and Development of Virtual Instruments

虚拟仪器是利用计算机显示器(CRT)的显示功能模拟传统仪器的控制面板,以多种形式表达输出检测结果,利用计算机强大的软件功能实现信号数据的运算、分析和处理.由I/O接口设备完成信号的采集、测量与调理,从而完成各种测试功能的一种计算机仪器系统。

Virtual instruments are a kind of computer instrument system, the control board simulating traditional instruments by showing functions of CRT, which expresses output results of detection in various forms, and realizes operation, analysis and processing of signal data by the powerful software functions of PC and accomplishes the work to gather, measure and debug signals by the I/O joint equipment and finally accomplishes different testing functions.
