虚拟教学实验室客户端软件研究与实现
|
摘要
随着高等教育的深化改革和招生规模的急剧扩大,我国高校普遍陷入了实验教学的困境。主要表现在硬件设施不足、教学时空受限、教学方法和内容落后。在计算机和网络通信技术快速发展的前提下,充分利用计算机资源的虚拟实验室成为解决这些现存问题、提高实验教学质量的重要选择。
论文借助于虚拟现实、可视化、虚拟仪器和网络通信等技术,对虚拟教学实验室系统及其客户端的架构、分析设计过程和实现方法进行了研究,设计实现了虚拟教学实验室系统客户端软件。客户端软件是整个系统的重要组成部分。它向用户提供丰富真实的元器件和与现实一致的实验操作平台,对实验教学具有重要的现实意义。
论文在分析虚拟实验室系统的结构模型基础上,选用改进的C/S模型,利用三层结构对系统进行设计,并且阐述了整个虚拟教学实验室系统的流程、组织结构及系统各部分完成的功能。
论文着重研究了系统客户端虚拟器件模型和模型库的建立方法,为实验者提供了丰富、逼真、规范的元件和仪器,并搭建了逼真的、操作方便的实验操作平台。同时,论文利用可视化技术和虚拟仪器技术研究了可视化计算在电路实验中的应用、实验信息的可视化显示及虚拟仪器子模块实现的方法,并研究了通信技术在数据收发传输中的应用。
论文最后对所研究实现的技术进行了功能测试。测试结果表明,利用该文阐述的技术与设计方法所构建的虚拟教学实验室客户端能模拟真实实验情景,并通过图形图像显示实验信息、进行结果分析及错误提示,拥有较好的交互性、适用性、器件的丰富性、实时性和扩展性。
With the revolution of high education and raise of number of student, the universities are puzzled by teaching of experiment. The main representations are deficiency of institutions, limitation of teaching time and place, backward in means and content of experiments. With the improvement of network technology and computer, virtual laboratory that takes full advantage of computer resource become an important choice of serving these problems and improve the quality of teaching.The paper adopts the technologies of virtual reality、 virtual instrument、 visualization and network communication and researches the structures of the virtual laboratory system and client-end. Client-end is an important section of whole system. It provides rich instruments and operation platform of experiments to users, and transmits data of experiments to server-end, and displays result of experiments. So, excellent design and technology of realization are important.This paper is based on analysis of the system model;it chooses C/S three-layer structure module. It studies working process of the whole system, structure and function of every module.The paper that emphasize studies establishment method of a model of virtual instrument and the model database, for the user provided abundant, lifelike, component instruments, and build a convenient experiment operation terrace.At the same time, the thesis makes use of techniques of visualization and virtual instrument , studies visual calculation in electric circuit experiment, visualization of method, and studiee the correspondence technique in data receiving and dispatch to deliver of application.Last, the paper tests the function of the technique of realization and study. The result shows that technique of the paper to elaborate and design virtual teaching laboratory can imitate the true experiment scene, and manifest experiment the result and information through the picture, analysis and hints of mistakes.And the system own characteristics of applicability, reciprocity,abundance,real-time and expansibility.
