基于LabView信号的处理网络虚拟实验室设计方法

Design Method of Signal Process Network Virtual Laboratory Based on LabView

阐述了构建网络虚拟实验室的必要性,着重讲述了应用数据库技术和网络化虚拟仪器技术构建网络虚拟实验室的方法,即利用LabView自带的数据工具包LabSQL和LabView中的DataSocket技术进行通信虚拟仪器设计。应用基于三层C/S(Client/Server客户机/服务器)模式的DataSocket技术,设计实现了自相关函数演示仪等试验仪器及试验数据的远程共享和试验仪器设备的远程控制。

This paper elaborates the necessities of creating internet-based virtual laboratory and emphatically gives an account of constructing internet-based virtual laboratory using database technology and networked virtual instrument technology. It utilizes LabSQL and DataSocket technology of the development software LabView to design virtual instruments for communications. The entire network system applies DataSocket technology based on three C/S （Client/Server） mode. The designed experimental instruments include autocorrelation function demonstrator and the remote sharing of the experimental data and the remote control of the experimental instruments.
