摘　　要：为满足"测试技术基础"教学的需要,采用虚拟仪器技术,基于LabVIEW平台,开发了虚拟仪器教学实验平台。该平台硬件包括USB7325A数据采集模块、DHF-2电荷放大器、YD-8加速度传感器和计算机,软件用LabVIEW 8.0编写。该平台能控制16路模拟量的采集并对采集回来的数据进行滤波操作、频谱分析、自相关分析,可以同时控制16路数字量的输入和输出。基于该平台,已开设了振动加速度测试、虚拟信号分析和数字量控制等实验,取得了较好的教学效果。A virtual instrument（VI） experimental teaching platform was developed to meet the teaching requirements of measurement technique foundation.Based on VI technique and LabVIEW,this platform was consisted of the data acquirement module USB7325A,the charge amplifier DHF-2,the acceleration sensor YD-8,the computer and the software programmed under LabVIEW8.0.It can control the analog signal acquirement of 16 channels and execute the filter,frequency analysis and autocorrelation analysis,and the digital signal input and output of 16 channels as well.Three teaching experiments have already been created on this platform,i.e.,vibration acceleration testing,the virtual signal analysis and the digital signal control.The teaching effect is prompted.
