摘　　要：主要介绍NI教学实验室虚拟仪器套件(ELVIS)在理工科院校电类专业实验教学中的应用,探讨以虚拟仪器为核心的数据采集系统及其实现信号检测技术的设计方案。首先介绍ELVIS的软硬件构成、功能,然后将传统电路原理实验与虚拟仪器技术相结合,在ELVIS平台上搭建了RLC串联谐振实验电路,利用ELVIS内部集成的仪器实现了激励信号的输入和响应信号的采样测量,最后利用LabVIEW软件实现了串联谐振电路Q值计算和幅频特性的绘制。实验效果表明,ELVIS平台比传统实验教学装置更具创新性、灵活性,充分调动了学生对实验内容的创造性。This paper introduces the NI Educational Laboratory Virtual Instrumentation Suite （ELVIS） in engineering colleges＂ electrical experiment teaching, explores design of data acquisition system and signal detection technology by using virtual instruments at a core. The paper firstly introduces ELVIS hardware and software structure and functions. Then we build experimental RLC series resonant circuit by combining the traditional circuit-principle experiment with the virtual instrument technology in the ELVIS platform. We use the ELVIS instruments to achieve internal integration of the input excitation signal and the response signal sampling measurement, and finally use LabVIEW software to implement the Q-value calculation and drawing amplitude-frequency characteristics. Experimental results show that the ELVIS platform is more innovative and flexible than traditional experimental teaching, fully mobilize the students＂ creativity in the experimental content.
