Programming And Application Of Virtual Instrument Based On USB-6009 Data Acquisition Card

Modern computer communication technology and measuring equipment, measuring tools, advanced technology combine to produce a virtual instrument. Virtual measurement technology, using a common shared hardware and software resources, data sharing, and can quickly and easily set up a variety of automated test systems. This not only can give full play PC data processing capabilities, but also real-time signal analysis and processing, storage, and graphics display.Modern test equipment and electronic test automated test technology development and a sign of maturity, performance continues to improve to improve. Digital information technology and the rapid development of computer communication technology, enables the programming and application of virtual instruments has become an emerging discipline, and in various universities, research institutes flourished, its importance is also reflected in various fields. This article discusses the methods of data collection and analysis, and the use of Lab VIEW graphical programming language development platform designed a function generator and USB-based data acquisition card application 6009, an example of the design shows the important modern equipment in the field of virtual position and prospects. In a sense, "the software is the instrument."In this paper, LabVIEW2012 software development platform, introduces the data acquisition and data processing virtual instrument development platform; On this basis, a brief introduction to the basic idea of virtual instrument software development, including instrument development process, the front panel and the block diagram of the preparation. The third chapter, chapter lists the virtual function signal generator, data processing programs based USB-6009 data acquisition card magnetostrictive sensors. The last chapter gives the full text of conclusions and outlook, further illustrate the important role of virtual instrumentation and data acquisition technology in the development of modern scientific research system.
