Research on the Deep Integration and Application of Digital Twins and Virtual Debugging Technology in Teaching Experimental Platform

Abstract

Digital Twin and Virtual Commissioning are the core enablement technology of Industry 4.0, which is deeply penetrated from the industry to the field of education, providing a new paradigm for innovating the traditional experimental teaching model. This paper proposes a teaching experimental platform construction solution that deeply integrates digital twins and virtual debugging technology. This solution takes Siemens TIA Portal and UGNX/MCD as the technical base. By establishing a high-fidelity mechatronic digital twin model and using PLCSIM Advanced to achieve real-time data interaction with virtual PLCs, it builds a complete "virtual and real mapping, rehearsal optimization, and linkage verification" closed-loop system. This article not only explains the overall architecture and key technologies of the system, but also theoretically analyzes the mathematical model of the virtual debugging process driven by digital twins. Through design comparison experiments, the improvement of the platform's teaching effectiveness was quantitatively evaluated. The data shows that after adopting this plan, the pass rate of student program debugging increased by about 40%, the time of experimental equipment occupied by 60%, and the depth of understanding of complex systems was significantly enhanced. This study provides replicable technical paths and theoretical support for the new generation of practical teaching of engineering science.
