网络虚拟仪器的开发研究

介绍了网络化虚拟仪器的基本概念,提出了一套基于.net框架下的Web网络化虚拟仪器的解决方案:采用.net组件技术构造用户界面组件、数据服务组件、信号分析组件、数据库服务组件和采集控制组件,根据需要,将上述组件灵活地部署到合适的位置,实现远程测试.按照这种解决方案设计了一套基于Web的网络化示波器,可以进行远端数据采集.并将数据库技术引入网络化虚拟仪器中,实现对信号的存取管理功能.

Research and Development of the Network Virtual Instrument

This paper introduces a basic concept of network virtual instrument and presents a solving scheme based on the .net framework for web network virtual instrument in which the component technology are used to construct UI component, data-service component, signal-processing component, DB-component, controlling component and data-acquiring component, in accordance to demand these component above can be flexibly put on the right place to realize remote test and control. In the light of the scheme, a set of network oscilloscope based on web is designed to remotely sampling data, and the technology of data base is successfully used to administer the saving and taking of signals in network virtual instrument .
