【摘要】 针对当前实验教学设备资源不足的问题，本文以实验教学资源的网络共享为目的，将虚拟现实技术与设备远程控制技术结合，研究了一种虚实结合的远程控制实验系统开发方法。文中还以倒立摆实验台为控制对象，开发了一套虚实结合的倒立摆远程实验原型系统。论文主要研究工作包括：第一、介绍了远程实验系统及相关领域的国内外发展现状，论述了在教学中采用远程控制实验系统的必要性和可行性，提出了虚实结合的远程控制实验系统总体架构，分析并选定了相应的实现方案。第二、在“实”的方面，提出通过网络技术将实验设备连接到网络上，实现网络化实验设备，使学生可以通过网络接触到真实的实验控制对象。为解决学生的并发实验申请问题和提高设备的使用率，还研究了协调实验设备资源分配的网络排队管理方法。第三、在“虚”的方面，为解决用视频方法传递实验场景对网络带宽的高需求以及观察角度难以调整的问题，提出用虚拟现实技术对实验设备进行三维建模和仿真，并用真实的实验数据对三维模型进行驱动，给远程用户以临场感。最后、以倒立摆为控制对象，采用Visual C++、Simulink和VRML混合编程，开发了一套虚实结合的倒立摆远程控制实验系统。在多种网络环境下对系统进行了测试，实验结果表明，该系统运行稳定、效果良好，具有良好的实用价值。更多还原

【Abstract】 In view of the current shortage of the experimental teaching equipment resources, aimedat the experiment teaching resources’ network sharing, this paper combines the virtual realitytechnology with the equipment remote control technology and introduces a developingmethod on remote control experiment system with virtual-actual combination. TakingInverted Pendulum as the control object, a prototype system of the remote control InvertedPendulum with virtual-actual combination is developed. The paper’s main research workincludes:Firstly, the remote experiment system and the present situation of development of therelated fields’ status at home and abroad are introduced, the necessity and the feasibility ofusing remote control experiment system during teaching process are discussed, the overallframework of the remote control experiment system with virtual-actual combination ispresented, and the implementation solutions are analyzed and selected.Secondly, on the “actual” side, it is proposed to connect the experimental equipments tothe web with the network technology, so as to make the experiment equipments networked,thus the students can contact the real experimental control objects through the web. In order tosolve the problems caused by the concurrent application of students and improve theequipment utilization rate, the network queue management method used to coordinate theexperiment equipment resources allocation is studied.Thirdly, on the “virtual” side, in order to solve the problems of the high networkbandwidth demand and the difficulty in adjusting the viewing angle which come along withthe method that using video to transfer the experiment scene, it is proposed to use the virtualreality technology to build the three dimensional model of the real experiment equipment, andto use real experiment data to drive the three dimensional model so as to give the distant usersthe feel of being present.Finally, taking the Inverted Pendulum as the control object, a remote control system ofInverted Pendulum with virtual-actual combination is developed with the mix programmingof Visual C++, Simulink and VRML. The system is tested under various networkenvironments, and the experimental results show that the system is stable, effective, andpractical.更多还原
