远程虚拟实验室的研究与开发

Remote Virtual Laboratory Research and Development

由于虚拟仪器(Virtual Instrumentation,VI)和网络技术的飞速发展,通过C/S或者B/S模式和虚拟现实技术来构建分布式虚拟教学系统的方法逐渐受到关注;文章介绍了利用现代教育技术把虚拟实验引入到实验教学中,构建完整的远程虚拟实验室系统化教学平台的解决方案;这个方法基于两种模式,软件共享模式和硬件共享模式,这两种模式结合虚拟现实技术能够最大限度利用现有软硬件资源和改善系统效率并降低建立系统的成本;这个最优化的解决方案应用到现代远程教育系统中,可提高教学质量和改善实验类型。

With the rapid development of virtual instrumentation and computer network, the approaches for deploying distributed virtual education system based on C/S （client/server）, B/S （browser/server） architecture and virtual reality technologies are becoming noticeable. The paper proposed the novel approach which introduces existing virtual technologies to modern remote education system and also draws up an effective and sophisticated solution. This method depends on combination of two typical schemas： software sharing and hardware sharing, which ensures the system recourses （software/hardware） utilized most efficiently. Meanwhile, involving virtual laboratory technology will enhance system efficiency and reduce the cost. An optimization solution based on proposed method can be applied to current remote education platform for improving teaching effect and experimental type.
