Based on the digital and knowledge assets of the container terminal, combined with 3D graphics technology, a visual operation management platform can be developed to build the digital twin of the whole terminal. Artificial intelligence and real-time processing technology of big data stream are used to grasp the current situation and realize the whole life-cycle analysis of terminal operations. By means of WEB 3D technology, the system can show terminal condition in real time and realize full-perspective tracking and data display of important terminal entities such as QC, RMG, AGV, vessels and yards. The three visual modes of Dashboard, Efficiency Analysis and Cruise provide multi-angle operation views of the port area, making the terminal operation more convenient and optimized, meeting the differentiated management needs of the executive level and the decision-making level.
