The Design Of Virtual Simulation Platform Based On LabVIEW

The main purpose of this article is to design a virtual simulation platform based on labview. With the rapid development of computer technology and promotion, the application of virtual instruments become more and more extensive. From the test and measurement to process control, From engineering design to experimental teaching, Almost across the various areas of science education. The LabVIEW programming software designed by National Instrument Company, Since its inception in 1986,which has focused on virtual instrument technology, has formed a very great advantage in the virtual instrument design after 20 years of development.The main purpose of this paper is to design a LabVIEW-based virtual simulation platform. This study is summarized below:First, introduce the concept of virtual instrumentation and software development system, the characteristics of LabVIEW. For the origins of virtual instruments, development and the advantages of teaching in the experiment were presented and summarized, The same time, LabVIEW graphical programming software, the history and characteristics of graphical programming approach to do a summary.Second, according to the virtual simulation platform architecture model, analysis and compare B/S,C/S mode which is common. Also, according to the characteristics of LabVIEW has chosen its own unique architectural pattern. And its implementation process has done a detailed.Third, the virtual simulation platform will be part of the experiment the contents were introduced. Including the design of operation amplifier circuit, the design of 555 oscillator circuit, the design of Voltage-frequency converter.Forth, introduce the network communication that LabVIEW commonly used, and made an introductory and compared.At last,make a simple summary of the platform, pointe out that the platform's innovative point, Also pointed out the shortcomings of the platform, And research for future work to further improve the prospects.
