【摘要】：高校传统实验教学以组为单位作实验,使部分同学难以全部参与和投入,没能充分了解和掌握实验全过程,仪器设备成本高,而且由于场地及课时的限制造成实验室设备也不能充分利用,最终浪费了学校大量的人力物力,同时学生还不能真正地掌握实验,学习效率较低。基于计算机技术的虚拟仪器的引入,不但可以节约大量仪器设备的经费投入,而且更新和调整的实验方法和手段使得实验室的实验教学设备保持其先进性,提高了实验教学和科研的质量与效率,是实验教学的一个新的发展方向,促进了实验室技术的进步。 LabVIEW编程语言灵活、开放、用软件代替了仪器功能,具有良好的用户界面、操作简单等优点,电工与电子类课程是电类相关专业学生学习的一个重要环节,课程理论性较强,在计算机上建立虚拟实验室,应用LabVIEW开发平台设计的虚拟实验仪器可以实现电工电子类课程中常见的实验,包括支路电流法、节点电压法、一阶动态电路分析、二阶动态电路分析、RLC串联谐振电路的研究、RC一阶的频率响应、3-8线译码器、8选1数据选择器、同步二进制计数器仿真等模块的设计,以及基于声卡的虚拟信号发生器设计和虚拟示波器的设计,以此可提高学生学习兴趣,弥补了硬件环境下实验教学的不足,改进了电工与电子课程实验教学的教学质量,提高了教学效果。
[Abstract]:The traditional experiment teaching in colleges and universities takes the group as the unit to do the experiment, which makes some students difficult to participate and invest fully, fails to fully understand and master the whole process of the experiment, and the cost of the instrument and equipment is high.And because of the limitation of the space and class hours, the laboratory equipment can not be fully utilized, which ultimately wastes a lot of manpower and material resources of the school, and at the same time, the students can not really master the experiment, and the learning efficiency is low.The introduction of virtual instruments based on computer technology can not only save a large amount of equipment investment, but also update and adjust the experimental methods and means to keep the laboratory experimental teaching equipment advanced.It improves the quality and efficiency of experimental teaching and research, is a new direction of development of experimental teaching, and promotes the progress of laboratory technology.The LabVIEW programming language is flexible, open, the software replaces the instrument function, has the good user interface, the operation is simple and so on. The electrician and the electronic class course is an important link which the electrician and the electronic class specialized student studies, the curriculum theory is strong,The virtual laboratory is set up on the computer, and the virtual experimental instrument designed by using the LabVIEW development platform can realize the common experiments in electrical and electronic courses, including branch current method, node voltage method, first-order dynamic circuit analysis, etc.Research on the second order dynamic Circuit Analysis of RLC Series Resonance Circuit Design of 1st order Frequency response 3-8 Line Decoder selected 1 data Selector, synchronous binary counter Simulation, etc.The design of virtual signal generator based on sound card and the design of virtual oscilloscope can improve students' interest in learning, make up for the deficiency of experiment teaching in hardware environment, and improve the teaching quality of electrical and electronic course experiment teaching.The teaching effect is improved.
