1、哈尔滨r拌大学硕十学{青论文摘要本设计针对建立远程可操控仿真实验仪器设备过程中所涉及的关键技术进行了研究。为网上虚拟电路实验室的客户端仿真实验平台设计了真实可交互仿真仪器界面软件，使实验室中使用的仪器以完全真实的面貌呈现在客户端仿真实验平台软件中。同时，根据网上虚拟电路实验室系统的整体要求，在系统的服务器端，利用NI的虚拟仪器产品构建了远程可操控实验仪器系统，实现了在客户端中设计的仿真仪器对应的实验仪器功能。整个远程可操控仿真实验仪器系统要模仿设计的对象是电路实验室中常用的YB4320A示波器、MF．47指针力．用表、DT9205M数字万用表、EMl716直流稳压源以及SGl69

2、2P信号源。系统设计无论是操作界面，还是仪器的各种测量功能、信源产生功能，都对这5种仪器进行了真实的模仿制作。根据仪器需要远程操控的功能要求，设计还研究了基于Intemet的远程数据传输和远程遥控的软件实现方法。本设计的创新之处在于完全真实地仿真构建了电路实验室中的5种常用仪器的交互界面和功能，实现了实验仪器的基于Internet的远程操控功能。真正意义上为网上虚拟电路实验室系统建立了一套基于Intemet远程可操控虚拟实验设备。关键词：网上虚拟电路实验室；仿真交互界面；虚拟仪器；远程操控哈尔滨¨辞人学硕十宁伊论文AbstractThedesignhasdeeplyresearc
