网络虚拟实验室的设计与实现

Design and Implement of Network Virtual Laboratory

国内多数高校的实验教学仍然采用实物仪器加简单数据分析的传统方式,这存在着诸多问题。在此利用网络技术和虚拟仪器技术,采用B/S体系结构,建立了网络虚拟实验室的框架模型。运用图形化编程语言LabVIEW软件,设计了相位差测量等相关的虚拟实验,并实现了网络发布。实践表明,基于网络的虚拟实验室,实现了远程控制和资源共享,可以节省大量仪器设备的经费投入,为实践教学提供了一种全新的现代化手段,有助于学生创新能力的培养。

The traditional way of physical instruments and simple data analysis is still used for experimental teachings in the most domestic colleges and universities.It exists many problems.A network-based virtual laboratory framework model was established with the network technology,virtual instrument technology and B/S architecture.A related virtual experiment such as phase difference measurement was designed,and Web publishing was implemented by means of LabVIEW software.Practice shows that the remote control and resource sharing can be achieved in the Web-based virtual laboratory.It can save the financing investment for the mass of equipments and instruments,provide a modern means for practice teaching,and help students to improve their creative ability.
