Li Weihong, a professor of the School of Geographical Sciences of SCNU, shared how her team utilized technology to contribute to the security work for the Beijing 2022 Olympic Winter Games in an activity held by the Guangzhou News Center on February 22.
Prof. Li Weihong shares the experience of her team's engagement in the Winter Olympics at the meeting held by the Guangzhou News Center on February 22.
The meeting themed on "Guangzhou' s Power during the Beijing Winter Olympic Games: Storytelling of Sporting Technology" invited guests from local companies and scientific research institutions to share the experience of their engagement in the Winter Olympics. Professor Li, also founder of a high-tech company in Guangzhou, said her team made use of digital technology to provide solutions of emergency management during the games.
According to Professor Li, a large number of emergency response plans needed to be made for possible emergencies prior to the Winter Olympic Games. Usually a mass of response schemes are made and conveyed in the form of words and schematics before the Games, but it is difficult for the security department to recreate every element in the emergency scene in traditional ways. Consequently, Dr. Li and her team made use of the advantages of virtual reality, spatio-temporal intelligence and digital twinning (a process in which a physical object, system or a being is recreated on a virtual interface) to propose an all-digital process including pre-plan, simulation, scenario inference and emergency command.
Premised on the all-digital process, a large amount of three-dimensional models were built up by Li’s team, including 3D-models of buildings and facilities such as the Wukesong gymnasium and dynamic models of athletes, volunteers, security personnel and audience. They formed a digital twin of competition venues for the Olympic Winter Games. On top of that, Dr. Li’s team took three months to design a plan evaluation and scheme optimization through field work and cooperation with the security department. It is with the help of this all-digital process that plan formulation was optimized, the actual effect of planning was improved and the Olympic Games proceeded smoothly and safely.
Professor Li has long been dedicated to the combination of spatio-temporal big data and public security, and her team’s preliminarily industrialized research achievements were achieved after joining in SCNU Qingyuan Institute of Science and Technology Innovation in 2021. Since then, their technologies and products have been widely used in public security, with applications such as disease control and prevention, security supervision and emergency management, all reaping remarkable social and economic benefit.
In recent years, with the advantages of talents, achievements and joint industrial bases, SCNU has been greatly promoting the transformation of science and technologal achievements into practical applications. This has shaped a new pattern of transformation that is based on innovation strengthening research institutes, and is oriented toward market application.
