摘要
虚拟仪器的绝大多数功能都是依靠软件实现的,包括仪器面板上的各种器件,如开关、按钮、传感器、数显表、显示器等,还有仪器内部需要执行的各种数据分析处理工作,如数字滤波、频谱转换等,因此NI公司曾提出"软件就是仪器"的口号。通常虚拟仪器软件编程有两种方法,一种是传统的面向对象的结构化编程,如VC++、VB、Delphi等,另一种是采用图形化编程,如LabVIEW、LabWindows/CVI等。这里以LabVIEW编程为例,介绍图形化语言在虚拟仪器编程中的优势,并以ABB公司的BSM系列伺服控制器为采集控制对象,实现了一个虚拟仪器实例。
Most of Vl＇s fmactions are achieved by software,including various data analyse processing on the front panel（switches,buttons, sensors, digital meters and digital displayers, etc. ） and inside the device （digital filtering and fl＇cquency conversion）. Normally, there are two ways to realize these functions, one is the Structured Programming based on the object, including VC ＋ ＋, VB, Delphi etc. , the other is Graphical Programming, including LabVEIW, LabWindwos/CVI,etc. Some of the advantages of Graphical Programming are described in VI＇s programming in this article,which has been proved by ABB＇s Servo Controller
