基于云的信号处理虚拟实验系统设计

Design of cloud-based signal processing virtual experiment system

虚拟实验室利用远程真实资源或虚拟设备资源构建实验系统,并通过实验教学资源的集中网络存储及数据库的统一管理来改善资源获取与信息交流方式。文中采用JSPWeb,Android应用开发,MySQL数据库等技术设计一个基于云的开放式信号处理虚拟实验系统,实现对现有实验室资源的网络化与虚拟化。该系统采用TCP协议与自定义应用层协议构建内部网络,通过云端服务器管理虚拟实验,使用应用网关监控实验板卡,并通过手机APP,Web浏览器为用户提供交互界面,用户接入网络即可进行实验操作。

The remote real resources or virtual device resources can be used to build the virtual experiment system of virtual laboratories,and the centralized network storage of experimental teaching resources and unified management of database are used to improve the resource acquisition and information exchange mode.The JSP Web technology,Android application development technology,MySQL database technology are used to design the cloud-based open signal processing virtual experiment system,which can realize the networking and virtualization of existing laboratory resources.The system uses TCP protocol and user-defined application layer protocol to build the internal network,manages the virtual experiments with the cloud server,adopts the application gateway to monitor the experimental boards,and provides a friendly interactive interface via App or Web browser.Users can perform experiment operation while accessing the network.
