随着计算机技术的发展和各种设备控制性能要求的提高，对现场数据实现数字化，进行实时采集，处理分析成为必须。其一般应用ＶＣ、Ｄｅｌｐｈｉ等通用的高级编程语言来实现，编程较复杂。本文探讨了应用ＤＬＬｓ实现图形编程语言ＬａｂＶＩＥＷ和通用Ｉ／Ｏ卡的连接，进行数据采集和分析以及通讯。实验证明采用这种方法省去了繁杂的语言编程，同时增加了应用的灵活性。 With the development of computer technology and the improvement of various equipment control performance requirements, it is necessary to digitize field data, acquire and analyze in real time. The general application of VC, Delphi and other common high-level programming language to achieve, programming more complicated. This article explores the application of DLLs graphical programming language LabVIEW and universal I / O card connection for data acquisition and analysis and communication. Experiments show that using this method eliminates the need for complicated language programming, while increasing application flexibility.
