毕业论文--基于WEB的虚拟实验室设计.doc

摘 要 随着计算机技术、大规模集成电路技术和通讯技术的飞速发展，仪器技术领域发生了巨大的变化，虚拟测试技术引入了仪器领域。将网络化虚拟仪器应用到实验室建设中，构成基于网络化虚拟仪器技术的虚拟实验室，为用户提供一个基于网络的实验教学、技术交流、共同研究的平台。 本论文首先介绍了基于Web 虚拟实验室的概念，并对其意义、特点以及设计原理、方法做了描述。然后就国内外虚拟实验室的研究现状和关键实现技术进行了简略介绍,并且结合课题的目标及现有的资源情况进行了研究和设计。设计主要包括虚拟仪器的开发和网站框架的搭建、网站留言板的建立、统一网站的整体风格、网站管理和使用说明、域名的设计与申请这几个任务。 本系统在应用服务上的设计采用了ASP 动态网页技术和数据库技术,并详细介绍了应用这些技术实现对客户端的管理。 关键词：网络化虚拟仪器；网络虚拟实验室；多层结构；浏览器/服务器；LabVIEW Abstract Along with the rapid development of computer science, large-scale integrated circuit technique and communication technique, the region of instrument technique takes place enormously, and virtual measurement technique has developed in the region. Using Networking Virtual Instruments into laboratory construction result in virtual lab based on the networking virtual instruments technology, which provides experiments, experience communication and cooperation platform. First of all, this paper introduces the concept of the virtual laboratory based on Web, and describes its significance, characteristic, design theory and method. Second, researches and key technologies for implementing the virtual laboratory are introduced briefly and aiming at the objective of the paper and the actual situation of the existing resources research and design. Major design include design virtual machines and the website framework for the structures, the establishment of the website visitors book, unity for the overall style, website management and the use of that domain name with the design for these tasks. The ASP and database technology are applied in the design of application server. The paper describes in detail how to implement the control and management of the accesses by clients with these technologies.
