摘要: 通过对虚拟仪器技术、虚拟仪器开发平台 LabVIEW 及相关方面技术进行调研，对实现虚拟仪器所用到的关键技术如前面板设计、GPIB 接口总线、远程前面板及数据采集等进行了研究。文章利用软件工具开发了虚拟万用表和示波器，展示了 Lab-view 前面板设计和程序流程图研发过程，对相应的实验过程及结果进行了验证，可以实现传统仪器的相应功能。同时基于客户机/服务器/浏览器模式组建了一种网络化虚拟仪器系统，以便于实现对虚拟仪器的远程访问和控制。Abstract: In this paper,virtual instrument technology and virtual instrument development platform-Lab-VIEW and related technologies have been investigated,and the key technologies of virtual instrument in-cluding the design of the front panel,DataSocket,GPIB interface bus,Remote Panels have been analyzed. The paper focuses on designing virtual oscillograph and virtual digital multimeter based on LabVIEW,re-spectively corresponding to the design process of front panel and the program block diagram,gives the cor-responding experimental process and results,which show the corresponding function of traditional instru-ments.This article also builds a networked system based on Client/Server/Browser pattern,which is ben-eficial to realize the remote visit and control of the virtual instrument.
