摘要: 远程教学打破了时间和空间的限制,在现代教学过程中扮演着越来越重要的角色,尤其是在抗击新冠疫情期间,远程在线教学成为了教学的必要手段. 针对实验教学需要操作仪器的特殊性,本文以“示波器的使用”为例探索并实践了基于物联网的远程操作物理实验的途径,通过LabVIEW实现对仪器的控制,利用LabVIEW中Web Sever 功能实现对仪器的远程操作,让仪器联网,采用Python编程中Tornado框架自主开发网站,为管理和远程操作仪器提供入口,再整合在线会议、电子教室、微信等免费平台与工具,自主搭建了成本低、用途广的远程实验操作系统;设计了包括视频指导、集中上课、自由练习等三部分的教学方案.

Abstract: Distance teaching can break the limitation of time and space, and plays an increasingly important role in modern teaching process. Especially during the fight against COVID-19, distance teaching became a necessary means of teaching. For experimental teaching, the operation of instrument is required. In this paper the use of oscilloscope is taken as an example to explore and practice the way of remote-operating physical experiment based on internet of things. The control of instrument is realized through LabVIEW, and the remote operation of instrument is realized by using the Web Sever function in LabVIEW. A website independently developed by Tornado framework in Python programming is adopted to provide an entrance for the management and remote operation of instrument. Free platforms and tools such as online conference, e-classroom and Wechat are integrated to independently build a low-cost and versatile remote experimental operating system. Teaching scheme including video instruction, centralized class and free exercise are also designed.

Key words: physical experiment, remote operating system, internet of things, LabVIEW
