摘　　要：在传统数据采集系统的基础上集成了USB接口和LabVIEW图形化编程语言的优点,这样不仅提高了性价比和通用性,而且使得系统更易于开发,数据处理简单,大大缩短了开发周期。介绍了LabVIEW对外部动态链接库及WindowsAPI函数的调用,同时也清楚地说明了LabVIEW中CIN节点的使用,通过上述两种方法成功实现了LabVIEW与USB驱动程序的数据交换,从而实现了以LabVIEW为应用程序的USB实时采集处理系统。Based on the traditional data collecting and processing system, this article tells us how to integrate the USB interface and LaBV/EW which is a type of graphic programming languages on this system. By doing this, it can not only improve the quality-price ratio and the common usage on other systems, but also make the system much easier to be developed than before. It can also simplify the data processing and shorten the cycle of the development process. This article also introduces the methods to use the dynamiclink library （DLL） and Windows API functions and make the use of CIN node in LaBVIEW clear. By using the two ways referred above, we can finish the data exchange between LabVIEW and USB driven program successfully which realize the real-time data collecting and processing system using LabVIEW as its application program.
