Abstract	With the continuous development of complex system diagnosis, prediction and system health management technology, driven by the emerging industrial information system and industrial intelligence, digital twin technology has become a new research hotspot in the field of intelligent manufacturing and intelligent operation and maintenance of complex systems. Digital twinning is to make full use of physical model, sensor update, operation history and other data, integrate multi-disciplinary, multi-physical, multi-scale and multi-probability simulation process, and complete mapping in virtual space, thus reflecting the whole life cycle process of corresponding physical equipment. This paper discusses the construction method of three-dimensional model of subway station, hardware design and predictive analysis of virtual-real mapping, including environmental quality monitoring, thermal comfort research, energy consumption prediction and so on. Digital twin technology will greatly improve the quality, benefit and level of urban rail transit line design, and produce obvious economic and social benefits. © 2021 IEEE.
