LabVIEW 是美国国家仪器公司（National Instrument，简称NI）的软件产品，自1986年1.0版本问世以来不断升级。LabVIEW是一个具有革命性的图形化开发环境，它内置信号采集、测量分析与数据显示功能，摒弃了传统开发工具的复杂性，从简单的仪器控制、数据采集到过程控制和工业自动化系统，，LabVIEW都得到了广泛的应用。由于LabVIEW采用了图形化的编程方法，因此LabVIEW又被称为G语言（Graphic Programming Language）-National Instruments LabVIEW is the (National Instrument, referred to as NI) software products since 1986. Version 1.0 came escalating. LabVIEW is a revolutionary graphical development environment, it built-in signal acquisition, measurement analysis and data display capabilities, eliminating the complexity of traditional development tools,　simple instrument control, data acquisition, process control and industrial automation systems,, LabVIEW has been widely used. Because LabVIEW uses a graphical programming methods, so LabVIEW also known as G language (Graphic Programming Language)
