基于虚拟仪器仿真的测控课堂实验演示教学方法研究

Investigation of Teaching Method of Experimental Demonstration in Measurement and Control Classrooms Using Virtual Instrument Simulation

课堂实验演示在高等教育特别是实验教学中显现了越来越显著的优势,能给予学生关于相关概念实时的验证和启发。本文探讨了一种基于虚拟仪器技术的模块化测控实验系统的开发与应用。该实验系统主要由模块化电路、数据采集器、PC摄像头和计算机组成,充分发挥了虚拟仪器技术的优势,能使教师在授课过程中使用真实的物理设备实时地解决电路问题,而不是单纯地讲解理论原理,有效地帮助了学生理解问题,符合工程专业学生传统的学习模式,对激发学生学习兴趣和创新思维起到了积极作用。

Experimental demonstrations in classrooms,which can help students validate relative concepts and thus get a good thought,are playing a more and more important role in high education especially in experimental teaching.The present paper investigated the development and application of an experimental system using the virtual instrumentation technology. The experimental system consists of module circuit,data acquisition device,PC camera and a computer,exploiting the advantages of the virtual instrument technology to the full. The proposed experimental system can help teachers avoid pure theoretical introduction and then solve the circuit problem in real time in classrooms.Besides,it conforms to the traditional learning style of engineering major,which can help students well understand knowledge and hence activate the learning interest and innovation thoughts.
