摘　　要：针对现代教育对远程实验的需求,采用基于RIA相关技术设计,开发了以《计算机组成原理》课程实验为背景的远程实验系统,实现传统C/S、B/S两种架构的结合。客户端通过Ajax的XMLHttp Request对象实现与服务器端的相互通信,提出了信息流最值动画算法,并利用HTML5的Canvas标签完成该算法的动画显示;服务器端利用ASP.NET完成服务器端与硬件设备的数据交互。该系统具有交互性高、实时性强、可跨浏览器等特点,能够动态地显示CPU数据通路中信息流的执行过程,满足了学生随时随地进行远程实验的需求,达到了与真实实验一样的效果,降低了学校硬件设备的成本,提高了实验资源的利用率。In view of the needs of modern education for remote experiment and the problems of C / S and B / S in the remote experiment system,the remote experiment system based on the RIA technology is adopted to design and develop the experimental system which is used to do the experiment of ＂ Principles of Computer Composition＂. The XMLHttpRequest object of Ajax is used to achieve the communication between the server and the client. The maximum and minimum animation algorithm for information flow is put forward by the client,and completed by the Canvas tag of HTML5. ASP. NET is used to complete the interaction between the server and hardware. This system has the characteristics of high interaction,real time operation and cross browser. It can dynamically display the execution process of the information flow in the CPU data path. The system allows students to do remote experiments at any time and anywhere while offering the same effect as real experiment. This system also reduces the cost of the hardware and improves the utilization of the experimental resources.
