用基于LabVIEW的虚拟仪器控制程序实现极谱仪数据的自动采集

Realization of auto-acquisition of polarographic data by virtual instrument control program written with LabVIEW

用直接插入计算机扩展槽的A/D转换卡将JP-2型示波极谱仪输出的电信号转换为数字信号,采用虚拟仪器开发软件LabVIEW编写数据采集与存储的控制程序,实现了用计算机实时采集与显示极谱谱图。

The electric output of an oscillographic polarograph （Model JP-2） was transformed into digital signal by using an A/D card directly inserted in the extended slot of computer. The control program for data acquisition and storage was written with LabVIEW to realize the real-time data acquisition and display.
