摘　　要：设计了一种基于NI ELVIS Ⅱ+的音调控制电路虚拟实验平台。该平台采用NI ELVIS Ⅱ+原型板完成电路的搭建,包括信号发生模块和信号采集模块;利用LabVIEW开发软件完成信号的发生、采集、处理和显示功能。实验平台具有良好的人机界面,能够根据学生的要求完成信号的发生、采集和处理,并自动保存波形图。实践证明,通过给学生提供开放的软件界面和自己搭建实验平台的机会,能够更好地帮助学生理解理论知识,增强实践和创新能力。A virtual experiment platform of voice control circuit based on NI ELVIS Ⅱ+ is designed. The platform uses NI ELVIS Ⅱ+ prototype board to complete the circuit construction, including signal generation module and signal acquisition module;and uses LabVIEW to develop software to complete the signal generation, acquisition, processing and display functions. The experimental platform has a good man-machine interface, and can complete the generation, acquisition and processing of signals according to the requirements of students, and automatically save the waveform. Practice has proved that by providing students with an open software interface and the opportunity to build their own experimental platform, they can better help students understand theoretical knowledge and enhance their practical and innovative abilities.
