基于Web的电工电子实验系统

A Web-based Electric and Electronic Experiments System

远程实验系统的研究是我国现代远距离教育的一项重要内容。文中详细描述了建立一个新的基于Web的电工电子实验系统的关键技术和开发过程。该远程实验系统结合现代计算机网络技术和数字电子技术,采用分布式Web集群体系结构和基于内容分类的请求分配策略,设计实现了驳接专用实验硬件装置的应用服务器,以及专用的实时任务调度算法,成功地建立了一个以远程实验为主的教育网站。该网站自开通以来已成为广大学生学习电路和电子技术基础知识的工具,取得了良好的成效。

It is an important matter to research on remote experiment system. This paper presents the development of a new webbased laboratory system for electric and electronic experiments and key technique in detail. In the remote experiment system, it adopts distributed webcluster architecture and contentbased dispatching policy for requests, combining with modern computer network and digital electronic technique. It designs and achieves a special application web server to support the interface for special experiment hardware, as well as a special realtime task scheduling algorithm running on this server. At last, it successfully establishes a web site for remote experiments and distance education. Now, the laboratory site has been an educational tool for most students to learn the basic principles of circuit.
