【摘要】：实验是专业课教学中非常重要的环节,是学生将理论知识与实际相结合的实践。但随着近年高校学生人数的增加,有限的实验资源无法满足实际教学的需求。为了解决该难题,本课题组开发了基于B/S模式的在线计算机网络虚拟实验室系统；目前,该实验系统已经建设完成并已投入使用。为了让该虚拟实验室系统的实验服务扩展至通信课程,本人研究了基于3Ds max和Virtools技术的虚拟实验开发方法,并参照《移动通信实验与实训》教材,开发了一套移动通信虚拟实验,本文详细阐述了该虚拟实验系统的开发过程。文中首先介绍了虚拟实验的背景,分析了国内外的发展情况,阐述了该课题的意义。接着,深入研究了三维虚拟实验开发技术,并通过比较若干种建模技术和交互技术给出了选择3Ds Max和Virtools作为开发工具的理由。然后从第三章开始介绍课题的设计内容,包括：(一)实验需求和设计原则、系统的B／S体系结构、虚拟实验的场景模型和功能、实验的操作流程及开发流程等。(二)在遵循建模准则的前提下,以CDMA测试板建模过程为重点对象,对三维虚拟实验场景和实验器材的建模以及模型“合并”和导出3Ds max的过程等进行了详细的描述。(三)详细地介绍了本系统交互部分的设计和开发过程,包括二维操作界面的搭建、三维漫游、设备展示、设备转载、设备连线、通信过程、实验计时、实验评分、实验数据保存等。最后,对实验的初始化和发布进行了说明。论文的结尾部分对本毕业设计的主要工作进行了总结,并结合实验室发展趋势和尚待解决的问题对课题提出了几点探讨。
[Abstract]:Experiment is a very important link in the teaching of specialized courses, and it is a practice for students to combine theoretical knowledge with practice. However, with the increasing number of college students in recent years, limited experimental resources can not meet the needs of practical teaching. In order to solve this problem, our team has developed an online computer network virtual laboratory system based on B / S model, which has been completed and put into use. In order to extend the experiment service of the virtual laboratory system to the communication course, I studied the development method of virtual experiment based on 3Ds max and Virtools technology, and referred to the teaching material of Mobile Communication experiment and practice training. A set of virtual experiment of mobile communication is developed, and the development process of the virtual experiment system is described in detail in this paper. In this paper, the background of virtual experiment is introduced, the development situation at home and abroad is analyzed, and the significance of this subject is expounded. Then, the development technology of 3D virtual experiment is deeply studied, and the reasons for choosing 3Ds Max and Virtools as development tools are given by comparing several modeling techniques and interactive technologies. Then it introduces the design content of the subject from the third chapter, including the requirement and design principle of the experiment, the B / S architecture of the system, the scene model and function of the virtual experiment, the operation flow and development flow of the experiment, etc. (2) taking the modeling process of CDMA test board as the key object, the modeling of 3D virtual experimental scene and experimental equipment, the process of model merging and the process of deriving 3Ds max are described in detail under the premise of following the modeling criteria. (3) the design and development process of the interactive part of the system is introduced in detail, including the construction of two-dimensional operation interface, 3D roaming, equipment display, equipment reprinting, equipment connection, communication process, experimental timing, experimental score. Preservation of experimental data, etc. Finally, the initialization and release of the experiment are explained. At the end of the thesis, the main work of the graduation project is summarized, and some problems that need to be solved in the laboratory are discussed.
