【摘要】 工科院校实验教学是培养学生专业素质的重要手段,基于 Internet 的远程控制实验室建设可能是解决学生数量多、实验室建设经费不足的有效途径。在详细分析了虚拟实验室、远程实验室和真实实验室的优缺点和目前国内外远程实验室存在的问题后,提出了远程实验室系统的功能需求,描述了远程实验室的系统体系结构和远程控制实验步骤,并分析了几种控制回路的特点和实现方法,最后,简要介绍了一个基于 Internet 的远程过程控制实验室的设计实例。更多还原

【Abstract】 Experiments are significant courses for cultivating students’ professional accomplishment in engi- neering institutes.Building remote control laboratory based on Internet may be an effective way of solving those problems such as large number students at school and lack of funds for buying enough experimental devices. After comparing remote laboratory with virtual laboratory and real laboratory,and pointing out the disadvantages of current remote laboratories,the functional requirements of remote laboratory are brought forward.Then the architecture of remote laboratory and the steps of performing an experiment in a remote laboratory environment are introduced.The characteristics of three types of control loop are discussed in succession.Finally,a design example of remote process control laboratory is given briefly.更多还原
