LabVIEW 外部代码接口技术的研究与应用
摘要 LabVIEW是一种功能强大的图形化虚拟仪器编程软件,广泛应用于仿真、数据采集、仪器控制、测量分析等嵌入式应用系统的开发。然而,在需要进行大量数据运算处理和数据采集时,LabVIEW显得有些力不从心。为此,本文研究了LabVIEW 外部接口技术,提出了LabVIEW与其他软件之间接口的方法,并且通过举例验证了各种方法的可行性,从而有效的解决了问题。

Abstract :LabVIEW is a graphical software with strong virtual instrument function, which has been abroadly applicated in simulation, data acquisition, instrument control, measurement and analysis of the application-embedded system exploitation. However, LabVIEW has not the ability to plex mathematic operation and data acquisition.
To this point, the LabVIEW external code interface technology is studied and several kinds of method of implementing the interface between LabVIEW and other softwares are put forword in this paper. The feasibility of the whole bag of tricks is verified by giving some examples and the problems are effectively solved.
Key Words:LabVIEW,virtual instrument,external interface,mathematic operation,data acquisition
引言
当前,虚拟仪器技术已广泛应用到各种自动化测试和测量领域,虚拟化已经成为仪器领域的发展方向。使用虚拟仪器技术,工程师们可以利用图形化开发软件来创建完全自定义的解决方案,以满足他们的特殊需要,这完全不同于专门的、只有特定功能的传统仪器。虚
