In traditional electrical control and PLC experimental teaching,there are some shortcomings such as fixed content,rigid methods,easy equipment damage,untimely knowledge updates,and occupation of experimental sites.A vir-tual simulation experimental teaching platform based on Siemens PLC is designed with intelligent garage control as the ob-ject.This platform not only compensates for the aforementioned shortcomings,but also adds rich and diverse content forms such as videos,animations,voice,and images.This is beneficial for improving students'learning enthusiasm.At the same time,Web-based information technology is applied to the simulation experiment teaching process.This approach breaks the limitations of time and space,which is more conducive to students'learning and mastery of knowledge points.
