Having attracted worldwide attention, Beijing 2022 Winter Olympics and Winter Paralympics came to a successful conclusion a few days ago, with “sci-tech Olympics” being one of the highlights. NCUT has received widespread media attention as it has given full play to its advantages in relevant disciplines, providing strong sci-tech support for the Games and contributing to the search for better possibilities of future urban lives.
On March 12, the TV programme "Fei Chang Xiang Shang", sponsored by Beijing Radio and Television Station, has invited Vice President Wang Li, Dean Shi Yuntao of the School of Electrical and Control Engineering, Deputy Director Han Fei of the Science and Technology Office and Professor Wang Lijun of the School of Informatics to introduce how NCUT supported the Games in scientific and technological aspects.
Vice President Wang Li introduced in detail how the Intelligent Transportation Team ensured the orderly assembly and evacuation of spectators during the Games. Specifically, the team was responsible for two major tasks: one was the assembly before and after the opening and closing ceremonies, and the other was the effective dispatching of athletes between venues. Despite the challenges of tight schedules, high expectations and high population density, the team designed an effective plan, meeting the demand of assembling 100 cars and 1000 people per day. Thanks to its geographic proximity to the Olympic Organising Committee and rich experience in smart transportation, the team secured the smooth traffic at remote assembly points while spectators were transported within the shortest time in the safest way.
Deputy Director Han Fei talked about his team's work on the development and application of a barrier-free guidance system for people with special needs. Affiliated to the special project of the National Key Research and Development Programme for the sci-tech Winter Olympics, the team researched and developed "intelligent wheelchair-assisted stairs" and "intelligent wheelchair with human-vehicle-road coordination". Aiming at "dismantling" the barriers to the Winter Olympics venues, the team provided barrier-free access services to help with crowd evacuation and to facilitate people with disabilities. To better understand the needs of people with disabilities, the team conducted thorough on-site research and survey of the stadium. The equipment was not installed in the National Stadium where games for athletes with disabilities are held until a series of rigorous tests. Moreover, these facilities are expected to help more people with disabilities in the future.
Dean Shi Yuntao presented his team's research on the "Risk Analysis System for Food Safety at Major Events". Adopting cutting-edge technologies such as deep learning, knowledge mapping, qualitative and quantitative techniques, and comprehensive integration, the system can predict personnel and food risks through its built-in AI analysis models. Specifically, information about food safety will be mapped out in terms of time and space, which will assist in decision-making at the site of major events and improve food security at major events. The system can also serve as an effective example for food safety monitoring and supervision in daily life and at major events after the Winter Olympics.
Professor Wang Lijun illustrated the development and implementation of the National Key Research and Project on "Panoramic Dynamic Exercise and Simulation of VR Emergency Medical Rescue for the Winter Olympic Games". The team developed a VR panoramic demonstration of the Winter Olympic Games emergency events, showing immersive scenarios of avalanches, terrorist attacks, infectious diseases, mass food poisoning and serious traffic accidents in a VR environment. With simulated exercises, the team helped medical personnel to familiarise themselves with the medical rescue process of emergency events in a hostile environment, so as to possibly improve rescue efficiency and minimise casualties. It was with the support of this simulation system that it took only 45 seconds for an alpine ski doctor to rescue an injured competitor at the Winter Olympics, greatly shortening the time it took for the medical team to rescue the injured and contributing to the protection of the athletes.
With its professional and disciplinary strengths, NCUT has completed major tasks in the preparation for and service of the Winter Olympic Games with high quality. Facilitating the Olympic Games with technological contributions, NCUT demonstrated its capabilities of scientific innovations and actively engaged in this global event with its wisdom and strengths.
