Research on the Development of Digital Twins in Construction Industry

With the development of the Internet of Things, big data, artificial intelligence and other technologies, driven by the emerging building information technology and smart city, digital twin technology has become an emerging research hotspot in the field of intelligent manufacturing and intelligent operation and maintenance of complex systems. This paper first sorts out the development of digital twin technology, the existing preliminary research planning and phased achievements, and then analyzes the application of digital twin technology in the construction industry from three aspects: the full life cycle of architecture, the smart site and the smart city. The research shows that digital twin technology can virtualize the building entity, transmit the data collected by sensors and so on, realize the comprehensive management and control of the building entity, and improve the building construction and operation efficiency. However, digital twin technology is not mature, and the interaction between entity and virtual body can be better realized by combining with other technical means such as AR. Finally, points out that digital twin technology development trend and prospect in the construction industry, the researchers in the field of management and control for complex systems provide certain reference.
