Research on the architecture of fully automatic yard section train inspection operation management system based on digital twin

Digital twin (DT) is one of the key technologies to promote the digital and intelligent development of metro vehicle bases. Related research is at the initial stage. How to realize the digital twin generation of vehicle bases is an urgent problem to be solved. The article briefly introduces the application of digital twins in the automatic field inspection operation management system of the vehicle base, and studies the system architecture. The digital twin technology realizes operation standard monitoring, operation quality backtracking, production safety monitoring, and business statistical analysis. And so on, so as to realize the "intelligent, efficient and safe" intelligent maintenance workshop.
