Research on the Situational Awareness and Operation Command System for the Winter Olympics Games
Ensuring the safe operation of the Beijing Winter Olympics presented three core challenges:the difficulty of identi-fying coupled risks between city and event operations,the challenge of monitoring spatial-temporal risks across urban opera-tions and pandemic contexts,and the complexities of cross-regional command coordination across the three competition zones and various departments.In order to address the challenge of identifying coupled risks,we developed a chain-based risk coupling assessment technology for the Beijing Winter Olympics,revealing the transmission and amplification mecha-nisms of these risks and filling a technical gap in the global risk identification for large-scale events.To overcome the chal-lenges of spatial-temporal risk monitoring,we established a big data monitoring and early warning model for safeguarding critical urban lifelines and developed pandemic spread risk analysis technology within social contact domains.To tackle the difficulties in coordinated command support,we pioneered a"data+task"jointly-driven command model and established a mixed-reality visualization and collaborative consultation system.This paper details the system's practical application using the specific case of warm snowmelt prediction in the Zhangjiakou competition zone.The relevant research outcomes provide a robust security support for the Winter Olympics and offer valuable insights for the safety management of other large-scale e-vents and urban security planning.
