使用LabVIEW开发平台编制的程序称为虚拟仪器程序，简称为VI。LabVIEW（Laboratory Virtual instrument Engineering Workbench）是一种图形化的编程语言，它广泛地被工业界、学术界和研究实验室所接受，视为一个标准的数据采集和仪器控制软件。LabVIEW集成了与满足GPIB、VXI、RS-232和RS-485协议的硬件及数据采集卡通讯的全部功能。它还内置了便于应用TCP/IP、ActiveX等软件标准的库函数。这是一个功能强大且灵活的软件。(Using the LabVIEW development platform known as the virtual instrument programmed process, referred to as VI. LabVIEW (Laboratory Virtual instrument Engineering Workbench) is a graphical programming language, it is widely used by industry, academia and research laboratories accepted as a standard data acquisition and instrument control software. LabVIEW integration and satisfaction with GPIB, VXI, RS-232 and RS-485 protocol communications hardware and data acquisition card full functionality. It also has built easy to use TCP/IP, ActiveX software such as standard library functions. This is a powerful and flexible software.)
