The Development Of VR Interactive Experiment Platform On Elvis-based AM And Demodulation Circuits

With the development of computer technology, the PC may be provided with a plurality ofexpansion slots, there have been inserted in the computer data acquisition card. It can make somesimple data acquisition, data processing after the completion of the acquisition of computersoftware, which is the prototype of the virtual instrument.Virtual instrument technology is the use of high-performance modular hardware, combinedwith efficient and flexible software to complete a variety of test, measurement and automationapplications. He is a multi-gate technology and computer technology combined with the product,is the existing computer technology and the flexibility to use software and high-performancemodular hardware together to build a powerful and flexible features variable computer-based testand measurement and control system to replace the traditional instruments (expensive, singlefunction) function. Virtual instrument technology to test measurement and automation brings aninnovation: virtual instrument technology to ready-to-use business technology and innovationintegrated hardware and software platform, providing one for embedded design, industrial controland test and measurement kind of new solutions.This paper will Multisim simulation technology, LabVIEW programming, networkcommunication technology such as the combination is designed for users to remotely use a virtualelectronic experiment platform. The platform offers a simulation of amplitude modulation anddetection experiments. Written by pure software simulation program implemented by providingLabVIEW remote front panel technology distribution network, users log in usingbrowser-experiment. Control experiments are "Virtual and" Elvis installed on the data acquisitioncard, NI Elvis tester and platform provides virtual instrumentation, test signal from the user on theremote collection of experimental apparatus, using virtual instruments for analysis and processing,and through shared variables read to your local computer, users achieve remote use. Aftercommissioning, the system is stable, it can basically meet the requirements of virtual laboratory.
