摘　　要：虚拟仪器是以计算机网络为基础,依据使用者的需求对仪器进行升级与改造,利用软件来完成对虚拟控制界面的布置和模拟相对应硬件设备的综合计算机系统。使用者可以通过输入设备(键盘、鼠标、触摸屏)来操控虚拟仪器面板,达到模拟使用真实仪器的目的。以LabVIEW软件为基础,针对电工电子实验中常用的虚拟示波器、虚拟信号发生器进行设计,分析设计了其工作的原理、设计流程、仪器面板、仪器各模块程序框图。The virtual instrument is an integrated computer system of the corresponding hardware device,which takes the computer network as the base.It is upgraded and reformed based on the user's demand and used to complete the layout of the virtual control interface and simulate.The user can control the virtual instrument panel through the input device(keyboard,mouse,touch screen)to simulate the real instrument.Based on LabVIEW software,this paper designs the virtual oscilloscope and virtual signal generator used in the electrical and electronic experiment,and analyzes its working principle,design flow,instrument panel and instrument block diagram.
