摘　　要：为了实现对冶金锯片基体磨削机床的改造利用,节约资源,达到厚度测量信息化、自动化的目的,采用软件LabVIEW和硬件数据采集卡NI PCI-6221进行了厚度数据采集系统设计。其中,采用LabVIEW的DAQmx函数进行编程设计,并且通过LabVIEW中驱动程序DAQmx实现对NI PCI-6221数据采集卡的驱动,用来完成数据的采集和控制。这种基于DAQmx方法的采集系统的设计在很大程度上提高了机床的生产效率,缩短了测量时间。In order to reach the purposes of saving resources and informationize-automatically collecting thickness data,in this paper,the grinding machines used for metallurgy saw body was reformed and applied.The design was based on LabVIEW software and NI PCI-6221 hardware data acquisition(DAQ)card.In the design,LabVIEW DAQmx function was used to doing programming,and the DAQ card of NI PCI-6221 was driven by DAQmx,so that data collection and control was performed.This collecting system that is based on DAQmx method improves production efficiency in a great extent,as well as saving measurement time.
