摘要
采用软硬件结合的手段,设计了一款用于普通实验室中信号检测及处理的虚拟示波器系统,系统软件部分采用具有图形化编程语言的LabVIEW,硬件部分主要由PCI-6014数据采集卡组成,负责采集外部数据,该虚拟示波器基本具有传统示波器的功能,还能使信号在数据采集卡和虚拟信号之间进行切换。在实际的应用中也可以根据使用要求的不同增加相应的功能。实验证明,该虚拟示波器运行稳定、性能良好,能满足普通实验室的一般要求。
Combining hardware and software technologies,one kind of virtual oscilloscope system used to detect and process the ordinary laboratory signals is designed in this paper.The software part is designed with graphical language of LabVIEW and the hardware part is mainly organized by the PCI-6014 data acquisition card to collect external data.In addition to traditional oscillographic functions,the oscilloscope system can also realize switching between data acquisition card and virtual signals.According to application requirements,different functions can be increased in the practical application.
