基于LabVIEW虚拟同步积分器的设计

LabVIEW是一种用图标代替文本行创建应用程序的图形化编程语言。它采用的数据流的思想和图形化的编程语言,极大地提高了编程的效率,从而能够方便快捷地设计虚拟仪器。设计了一种基于LabVIEW的虚拟同步积分器,利用LabVIEW软件提供的控件和函数,设计了两种虚拟同步积分器的信号处理方法,即直接法和间接法。虚拟同步积分器可用于以同步积分器及微弱信号检测为核心内容的实验教学,不仅能在一定程度上缓解实验教学的仪器压力,同时能够加深学生对理论知识的理解。随着虚拟实验技术的成熟,以虚拟仪器为基础构建的新型实验室将有助于实现开放的实验教学。

Design of Synchronous Integrator Based on Lab VIEW Virtual Experiment Instrument

Lab VIEW is a graphical programming language,which uses icons instead of lines of text to create applications. It uses data stream of thought and graphical programming language,which greatly improves the efficiency of programming,enables quick and easy design of virtual instrument. Based on the use of Lab VIEW software providing controls and functions,two virtual synchronous integrator signal processing methods,namely,direct and indirect methods,are designed. Virtual synchronization integrator can be used to the synchronize integrator and the weak signal detection as the core content of the experimental teaching,not only to a certain extent,to ease the pressure on experimental teaching instrument,but to deepen students＇ understanding of theoretical knowledge. As the technology of virtual experimental instrument to build virtual instrument based on new laboratory matures,it will help to achieve an open experimental teaching.
