摘　　要：利用LabWindows/CVI虚拟仪器专用开发平台结合PCI-9112数据采集卡设计了一种多功能数据采集系统。系统充分利用了PCI-9112的通道自动扫描功能(continuous-scan-channels)和双缓冲模式(double-buffered mode),实时、高速地采集八路模拟输入信号,并将波形数据保存至计算机的硬盘,方便以后查看。应用结果表明,系统检测精度高,运行稳定,具有一定的实用性和推广价值。Based on virtual instrument technology, a data acquisition system was designed by use of the LabWindows/CVI combined with PCI-9112 data collecting card. Sufficiently utilizing the PCI-9112＇s function of continuous-scan-channels and double-buffered mode, this kind of system can synchronously display eight-channel analog input signals. And the measured shape of the waves could be stored to the hard disk of the PC, they could be saved for a long time and be showed many times. The application shows that this system rims stably and accurately. The technology and methods adopted in the system are practical and worthy to extend.
