We deployed the **"Cloud Intelligent Aviation" Airport Brain and All-Scenario Perception Service System**. The solution establishes a comprehensive IoT perception network and digital twin covering the airfield, terminals, and transportation centers, enabling end-to-end, visualized, and minute-level precision management of aircraft flow, passenger flow, baggage flow, and traffic flow. For passengers, it offers seamless, contactless services and personalized dynamic guidance. For operations, AI-driven algorithms enable intelligent gate allocation, abnormal baggage alerts, and predictive maintenance of facilities, shifting decision-making from experience-based to data-driven intelligence.
