The biggest difference between discrete event systems and traditional dynamic systems is that their state changes are driven by events rather than time. Therefore， most existing software cannot effectively study discrete event systems. With the rapid development of computer technology， virtual instrument technology has been widely applied in various fields. However， in the teaching process of virtual instrument technology， simply explaining textbook content can easily lead to students losing interest. Therefore， based on the event structure in virtual instruments， this article studied the preliminary application of virtual instrument technology in discrete event systems. This not only provides new ideas for scholars in the research of discrete event systems， but also realizes the teaching exploration of combining virtual instrument technology with discrete event systems.
