虚拟仿真电阻式传感器设计

The Design of the Virtual Simulation Resistive Transducer

针对学生难以认识和掌握传感器机理、设计和使用问题,该文将Multisim虚拟仿真技术与模拟电子技术课程相融合,并以项目为载体,设计了温度、压力和气体3种类型的虚拟仿真传感器,给学生提供了接触传感器的机会,实现从敏感元件、电路设计和使用全方位引导学生学习和掌握传感器技术相关知识。实践表明,研发虚拟仿真传感器,能够创新实验教学内容,激发学生内在学习动力,提高学生工程实践能力,同时还提升了教师育人能力,提高了理论课程实用价值,也为普及工程教育和创新创业教育提供了必要的条件。

It is difficult for students to learn and master the mechanism,design and use of transducers. In order to solve this problem,we applied the Multisim virtual simulation technology in the course of analog electronics technique and designed three virtual transducers for temperature,pressure and gas measurements. This practice provides students a chance to get in touch with transducers,learn and master the comprehensive knowledge of transducer technique,including the sensitive component,the circuit design and application. Research and development of the virtual simulation transducer could innovate the experiment teaching content,inspire the learning motivation of students,and improve their hand-on abilities. Meanwhile,it also promotes the teaching ability of teachers,improve the practical outcome of the course,and provide the necessary condition for popularizing the engineering education and innovative entrepreneurship education.
