虚拟仿真技术在“传感器技术及应用”教学中的应用

Application of Virtual Simulation Technology to the Teaching of “Sensor Technology and Application”

作为电子类专业的核心课程,传感器技术及应用在理论教学中理论性强、难教、难懂,实验教学中重视结果、缺乏理论分析,导致理论与实践教学不统一。针对该现象,本文提出运用LabVIEW虚拟仪器图形化编程软件和Multisim电路仿真软件创建传感器技术及应用虚拟仿真教学平台。针对铂热电阻传感器为例,通过Multisim电路设计分析,调用自定义LabVIEW虚拟仪器完成数据的获取和分析,进行虚拟仿真实验。教学结果表明:解决了理论与实践不统一问题,同时弥补了实验教学中场地不足、设备落后的问题,提高了学生的学习积极性和教学质量。

As the core course of electronic specialty, sensor technology and its application in theoretical teaching are theoretically abstract, difficult for teachers to teach and difficult for students to understand, and what's more, paying attention to the results in experimental teaching and lacking theoretical analysis result in the disunity of theoretical and practical teaching. In view of this phenomenon, this paper proposes to use LabVIEW virtual instrument graphical programming software and Multisim circuit simulation software to create sensor technology and application virtual simulation teaching platform. Taking the platinum thermal resistance sensor as an example, through the design and analysis of Multisim circuit, the data acquisition and analysis are completed by calling custom LabVIEW virtual instrument, and the virtual simulation experiment is carried out. The teaching results show that the problem of disunity between theory and practice is solved, at the same time, the problems of insufficient space and backward equipment in experimental teaching are made up, and the students' learning enthusiasm and teaching quality are improved.
