【摘要】 远程监控与虚拟现实技术相结合是当今工业监控领域的重要研究方向。X3D标准(eXtensible 3D Standard)已经被广泛应用于创建基于网络的交互三维虚拟空间。本文针对面向远程监控扩展X3D标准的问题,从X3D技术在远程监控中的应用与扩展、基于X3DToolKit的X3D扩展方法、基于OpenVRML的X3D扩展方法、远程监控“过程控制综合实验平台”原型系统等方面进行了研究,其主要内容包括:第一,分析了目前X3D技术在远程监控中的几种应用方式和存在的问题,定义了X3D通讯组件以便扩展X3D系统的数据交互接口,实现X3D技术与远程监控技术的无缝连接。第二,基于开源工具包X3DToolKit,研究了创建X3D标准的新节点和新处理器的方法,设计了一个利用键盘等外部设备直接修改几何节点Box的size域的应用实例。第三,基于开源工具包OpenVRML,定义了应用于网络数据通讯的NetSensor节点和应用于本地数据通讯的DataSensor节点,实现了虚拟场景与外部应用程序直接通讯;提出了设计智能监控单元节点的思想和方法;开发了基于MFC的VRML/X3D浏览器。最后,利用以上的研究成果,基于扩展的OpenVRML工具包开发了具有一定实用价值的远程监控“过程控制综合实验平台”的原型系统。X3D通讯组件的引入,能够更加容易的将X3D技术整合到监控系统之中,消除了X3D在工程应用中的许多限制并改善了监控软件的交互环境,在工业监控领域具有很好的理论价值和应用前景。更多还原

【Abstract】 The integration of Remote Monitoring and Control Techniques and the Virtual Reality Techniques is an important subject in researches in Industrial Monitoring and Control Field. X3D (eXtensible 3D) standard is widely applied to create interactive three-dimensional world through the Internet. The thesis researches some problems of extending X3D standard based Remote Monitoring and Control Techniques. With the beginning of analyzing actual application and extended application of X3D Techniques in Industrial Monitoring and Control Field, the thesis researches the methods of extending X3D standard based the toolkits of X3DtoolKit and OpenVRML respectively and designs a prototype system based OpenVRML. The main content is introduced in detail as follows:Firs of all,after having analyzed the actual application mode of X3D Techniques and existent problems in Industrial Monitoring and Control Field, the thesis defines the X3D Communication Component so that extending interactive interface of X3D system and achieving seamless link of X3D Techniques and Remote Monitoring and Control Techniques.Secondly, after having researched on methods of creating new nodes and processors of X3D standard based an open source toolkit named X3DToolKit, the thesis designs an application instance in which the size field of Box node can be modified directly by keyboard.Thirdly, the thesis defines NetSensor node and DataSensor node which are used for data interacting through Internet or local applications. These nodes make Virtual Scene Graph can communicate with external monitoring and control applications directly. Otherwise, the thesis mentions consepts and methods of designing intelligent Monitoring Unit Nodes, and designs a VRML/X3D browser based MFC.Finally, the thesis designs a prototype system named remote monitor and control“The platform of process control experiment”based extended OpenVRML. This prototype system has a definite applied value.With X3D Communication Component, it is much easier to integrate X3D techniques with Industrial Monitoring and Control applications and to make X3D applied more freely and offer the applications much better environment to communicate, so X3D based Remote Monitoring and Control Techniques have great academic significance and promising applied prospect.更多还原
