基于嵌入式虚拟仪器的电工测量实验研究

Research on electrician measurement experiment based on embedded virtual instrument

针对当前电工测量相关课程学时较少、学生兴趣淡等问题,以培养实践能力为出发点,在“电测仪表”和“嵌入式虚拟仪器与电工测量”等课程中,在传统的课堂授课模式基础上,增加虚拟仪器和嵌入式系统知识点,利用LabVIEW ARM平台快速高效地开发基于ARM Cortex-M3处理器的应用程序。该平台简单易学,在方案设计等环节能给学生提供更多的选择发挥空间,调动学习的主动性,较好地拓展电工测量知识面,对于电路、电工技术等课程知识及技能的巩固提高也很有裨益,并为后续虚拟仪器和嵌入式系统等课程学习和开展创新实践活动奠定基础。

There are many problems with electrician measurement related courses,such as less school time and low interest of students.In order to develop practical skills,we add virtual instruments and embedded system knowledge in“Electric Measurement Instrument”and“Embedded Virtual Instrument and Electrical Measurement”courses,based on the traditional classroom teaching mode.We use LabVIEW ARM to develop applications running on ARM Cortex-M3 processors quickly and efficiently.The platform is simple and easy to learn.It provides students with more choices in project design,also mobilizes the initiative of study and expands electrician measurement knowledge.It is also beneficial to the consolidation and improvement of knowledge and skills in courses such as circuits and electrical technology.These experiments lay the foundation for innovative practices and follow-up virtual instruments and embedded systems courses.
