基于Web的网络测试仪器及应用

摘要

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.%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.
