基于虚拟仪器的电工实验

Virtual instrument used in electrotechnics experiments

介绍了一种虚拟信号发生器和双通道虚拟示波器的实现方法,该仪器为PC-DAQ系统,软件部分采用基于图形化编程语言LabVIEW编写,在此基础上完成了积分电路的实验,得出了积分电路的输出波形。实验结果表明,该仪器精度和稳定性都满足大学实验教学的要求,与传统仪器相比有着自身的优势,具有较高的实用性。

This thesis focused on realization of a virtual signal generator and dual-channel virtual oscilloscope. The virtual instruments was of PC-DAQ system and its software was written by graphical programming language LabVIEW. Based upon this, the authors carried out integral circuit experiment and got its output wave. The experiment results show that this virtual instrument has obvious advantages over traditional instrument in its excellent performance in precision and stability for college experiment teaching, thus of high feasibility and practicability.
