LabVIEW的虚拟仪器数据接口设计与实现

LabVIEW-based data interface designing and realization for virtual instrument

LabVIEW是一种基于G语言的虚拟仪器开发环境 ,其数据接口设计是进行系统功能扩展的重要方法。本文在分析虚拟仪器软件LabVIEW特点的基础上 ,给出了虚拟仪器的数据接口途径 ,设计并实现了两种LabVIEW的数据接口 ,重点解决了虚拟仪器中的大数据量数据处理与模块共享问题。最后给出了设计实例。实践表明 ,此机制高效、易行 。

This paper introduces virtual instrument and its development environment-LabVIEW,design and realizes the advanced technology-data interface,which is a general method for calling external code from LabVIEW 。It has been proved that this method is efficient,practicable,and it is a good way improving the LabVIEW's capacity of sharing data with other applications of Windows.
