基于LabVIEW的PCI数据采集系统设计

Design of PCI data acquisition system based on LabVIEW

利用虚拟仪器技术与PCI数据采集卡构建了一个虚拟仪器系统。详细介绍了通过Lab-VIEW CLF节点调用PCI数据采集卡驱动函数的操作过程,以及LabVIEW程序框图的开发流程。该仪器具有数据采集、波形显示、超限报警、数据存储等功能。

A virtual instrument system is established by using LabVIEW and PCI data acquisition card. This paper introduced the operation process of calling PCI data acquisition card driving function by LabVIEW CLF node, and the development of LabVIEW block diagram. The instrument has the ability of data acquisition, waveform display, overload alarm, data storage, and so on.
