摘要
针对构建软件仿真实验、硬件实验和虚拟实验三位一体的通信原理实验体系需求,结合数据采集的关键技术,设计了虚拟实验平台总体框架及其功能模块。采用LabVIEW和NI USB-6211数据采集卡实现了通信原理仿真和通信原理实验两大功能模块。其中,通信原理实验模块利用数据采集卡采集通信原理实验箱的实验数据,实现了实测波形与参考波形的对比,完成了远程通信原理仿真学习和虚拟实验数据采集功能。
According to the requirements of communication principle platform that is comprised of software simulation platform,hardware teaching experiment and virtual simulation platform,and combining the key technology of data acquisition（DAQ）,this article designed the whole frame and function module of virtual simulation platform.It realized the function modules of the simulation and experiment of communication principle through the data collection card based on LabVIEW and NI USB-6211.The real-data of communication principle experiment platform were collected based on the data collection card.The contrast of testing wave and reference wave was realized and the function of the data collection that can learn communication principle in the long-distance and the function of virtual experiment data collection were fulfilled.
