Our first step is to realize 'virtual reality mapping', and then gradually promote it in accordance with the goals of 'virtual reality analysis',' virtual reality optimal control 'and' virtual reality symbiosis'." Liu Bin, deputy director of Shanghai Municipal Transportation Commission, said at the "connecting the future" Shanghai traffic digital twin governance sharing meeting held on the afternoon of the 4th that nowadays, many "meta universe" application scenarios have been integrated into people's daily lives. In Shanghai, scenes such as ports, airports, construction sites and road networks have enhanced the efficiency of fine urban governance in the "virtual reality combination" of digital twins. (Shanghai has built a digital twin airport to promote the airport's intelligence in eight fields, including safety, operation, service, operation, transportation, environment, freight transport and management. (photo provided by Shanghai Municipal Transportation Commission) the new level digital twin port of the shipping center has been completed. Shanghai is a big Oriental port, and Yangshan phase IV automation terminal has taken the lead in launching the digital twin system. Shangang group said that the Yangshan phase IV digital intelligence platform is an effective application and breakthrough attempt in the field of container terminals by using twin technologies and intelligent algorithms on the basis of big data applications, and is an important direction for data enabled port production and lean management in the future. Compared with the traditional port operation management, the digital twin platform has incomparable scene advantages. Taking supervision as an example, comprehensive digital production equipment, 5g network system, producers, production managers and equipment operators can use digital twin mobile equipment at any time and at any place to fully grasp the production and operation status of the port. With its powerful 3D scene rendering capability, the digital twin platform can not only quickly locate and observe the operation situation of the port and the layout of container stacking areas, but also quickly locate and observe the movement of equipment components. It is understood that the on-site scene restoration capability of the digital twin platform is far superior to video systems and UAV Systems in breadth and depth. In addition, the digital twin can simulate the meteorological environment, which can model the impact of production processes under different meteorological environments and design corresponding production plans.

The intelligence of Shanghai airport includes two levels: individual and system. The intelligence of individual airport is the foundation, focusing on key areas such as safety, operation and service, so as to realize visible situation, command and accurate flight. The intelligent airport system is based on individual intelligence to achieve regional management of cities and fine management and control of enterprises. For example, the Shanghai Airport Group flight situational awareness platform integrates a large number of real-time information such as runway monitoring, parking capacity, aircraft support nodes, aircraft taxiing routes, and passenger distribution in the terminal
