基于Web的网络测试仪器及应用

Web-based network instrument and its application

介绍了网络化虚拟仪器的基本概念,分析了网络化虚拟仪器的结构,提出一套基于.net框架下的Web网络化仪器的解决方案。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、数据库连接组件和数据采集组件,根据需要部署到合适的位置,实现远程测试分析。用户可以在远程登录Web服务器,用户界面组件和信号分析组件自动下载到客户端并嵌入浏览器运行,在浏览器中可以进行信号的测试与分析。

This paper introduced the basic concept and structure of network virtual instrument.A solving scheme based on the net framework for web network virtual spectrum analyst was presented.Component technology was used to construct UI component,data-service component,signal-processing component,DB-component and data-acquiring component,which can be placed properly to realize remote test and analysis.The UI component and signal-processing component can be automatically downloaded from the server when a remote user logins web server.These components embedded in the user＇s browser can communicate with data-service component to transfer dada.Users can analyze and test the signal.
