基于计算机LabVIEW的虚拟仪器的设计实现

Design and implementation of virtual oscillograph based on the virtual instrument technology

论文采用计算机虚拟仪器开发平台LabVIEW及PCI-1200数据采集卡等相应硬件设计实现了虚拟数字示波器,所谓虚拟仪器技术,就是用户,根据测试任务的需要来定义和设计仪器的测试功能,即通过应用程序将通用计算机与功能模块硬件结合起来,用户可以通过友好的图形界面来操作这台计算机,虚拟仪器主要由硬件和软件两部分组成,其中硬件部分主要包括计算机和必要的计算机仪器硬件模块。LabVIEW图形化程序设计基于面向对象技术和数据流技术。通过实验证明虚拟实验系统能很好完成对信号的采集、分析处理等工作。具有快速、准确等特点。

the paper by using computer virtual instrument development platform LabVIEW and PCI-1200 data acquisition card etc corresponding hardware design realized the virtual digital oscilloscopes,so-called virtual instrument technique is users,according to the need of testing tasks to define and design instruments test functions,namely through the application of computer and function module generic hardware combined,users can through friendly graphical interface to operate the computer,as in operating their definition,the design of your own a single instrument,thus completing the same tested amount of collection,analysis,judgement,display,data storage,etc.Virtual instrument mainly by both hardware and software components,including hardware mainly includes computer and necessary computer instrument hardware modules.Software is the LabVIEW graphical application program design based on the object-oriented technology and data flow technology.At last,through experiment proof virtual experimental system was completed signal collection,display,analysis,etc,compared with traditional instruments work is rapid,simple and accurate etc.Characteristics.And analyzes the problems that need further in-depth study further expand the direction and with the potential economic benefits.
