【摘要】 随着计算机技术的发展,采用LabVIEW的虚拟仪器技术得到了广泛应用;使用LabVIEW对信号进行分析和处理依赖于数据的采集,数据采集通常的方法是使用数据采集卡,但如PXI,PCI等数据采集卡价格较贵,使用也不方便,影响了LabVIEW的推广和使用。USB总线具有使用方便、接口简单、传送速率高的特点,使用USB接口进行数据的采集不失为一种可供选择的方案。介绍了一种LabVIEW和USB设备进行直接数据通信的实用方法。更多还原

【Abstract】 With the development of computers technology,the application of virtual instrument which using LabVIEW becomes more and more widely.Using LabVIEW to analyze and process signal depend on the data acquisition,the traditional data acquisition cards such as ISA,PCI data acquisition card have are expensive and not convenient to use.USB interface possesses the characters of Plug-and-Play and high speed,it is also a feasible way to achieve data acquisition.This article introduces a technique to Realization of USB interface communication based on LabVIEW.更多还原
