【摘要】 随着网上教育的广泛应用,基于网络的虚拟实验的研究逐渐被人们关注。虚拟实验是现代创新教育的重要手段,是实现教学资源共享与优化配置的重要方式。本文通过对虚拟现实、虚拟实验的构建理论、建模方法以及关键技术的分析研究,提出了一种基于网络的分布式虚拟实验系统的解决方案。该虚拟实验系统平台基于实验室Intranet、采用浏览器/服务器模式,在满足实验室内部进行虚拟实验的前提下可以同时进行远程虚拟实验;该虚拟实验平台的建设以VRML技术为基础,并结合其他虚拟现实技术在计算机上模拟网络环境下实验环境、实验对象和实验过程,使用户在同一网络环境下完成虚拟实验;系统采用表示层、功能层和数据层的三层结构;系统界面根据实验教学各种环节,划分为虚拟中心、交流中心、资料中心、下载中心四个板块进行设计。系统设计过程中对系统建模问题和交互问题进行了重点研究,给出了停车场虚拟实验系统、智能照明虚拟实验系统和智能消防虚拟实验系统等应用实例。最后结合系统平台搭建中的不足对以后进一步深入研究的几个方面做简单的展望。文章提出的基于网络的分布式虚拟实验系统的解决方案,可实现对我校智能建筑实验室现有实验系统的补充(比如停车场等不宜于在实验室演示的实验),并可用于其他专业或基础实验室构建虚拟实验系统,具有较强的实际应用价值。更多还原

【Abstract】 With the extensive application of online education, research of web-based virtual experimental system is concerned gradually. Virtual experiment is an important means in modern education, for sharing and optimizing teaching resources.Based on the analysis of virtual reality, virtual experiments construction theory, modeling methods and the key technologies, the article proposes a distributed Web-based solution for Virtual experimental system. The system is based on laboratory Intranet, using browser / server model, can do long-distance virtual experiments; The system simulates experimental environment, experimental subjects and experimental process based on VRML technology and other virtual reality technology. The system adopts three-tier structure of the presentation layer, the function layer and data layer and the interface is divided into four parts of virtual center, exchange center, data center, download center according to the various aspects of teaching. The research focus on the system modeling and interactive mode, then gives application examples such as the virtual experimental system for parking, intelligent lighting system and fire fighting system. Finally, the article proposes prospects for the platform in the further study.The distributed Web-based solution for Virtual experimental system, can supply our intelligent building laboratory system ( such as parking lot that is not advisable to perform in laboratory ),also, can be used in other professional or for basic laboratory, so that it has practical value.更多还原
