基于虚拟仪器技术的传感器仿真实验软件开发

Development of Sensor Simulation Experiment Software Based on Virtual Instrument Technology

利用Lab VIEW和Multisim的数字和模拟仿真功能完成了传感器仿真实验开发。其实现步骤包含建立传感器模型、设计测试电路以及构建良好的人机交互界面,将理论知识、实验内容和综合应用有机结合在一起,让抽象的理论知识以图形图像的形式直观显示,形成开放式虚拟仿真平台,以便于学生能随时随地通过网络进行远程仿真实验,对教学实践起到很好的辅助作用。实践结果表明,开发的传感器仿真实验软件有利于提高学生的学习兴趣,加强对传感器原理和测量电路的理解及应用,降低实验过程中的误操作率,减少不良的实验现象,进一步提高了学生知识综合应用的能力;同时在不增加课时的前提下,提高了教学的有效性。

The implementation steps of sensor simulation experiment based on Lab VIEW and Multisim include the establishment of the sensor model,the design of measurement circuit and well-designed GUI.The simulation experiment is released to the network,so that students can perform it on the Internet anytime anywhere.The sensor simulation experiment displays the theory knowledge in the form of graph,it combines the theory knowledge,experiment and application organically.The results show that sensor simulation experiment can improve the study interest,strengthen the understanding of the principle,reduce the incorrect experimental operations,and improve the teaching and learning efficiency without increasing the class.
