The Winter Olympics is not only a global sports event, but also a stage for the host country to demonstrate its technological strength.
From the use of AI to customize training programs for athletes, to environmentally friendly ice-making technology in venues, smart restaurants, heated seats, and upgrades of competition equipment, technology empowers the Beijing Winter Olympics to make ice and snow more "smart".
From hosting, participating to watching, the wonderful Winter Olympics event has won praises from athletes and spectators from all over the world.
Create sustainable smart venues
The opening ceremony of the Beijing Winter Olympics outlines a minimalist and beautiful oriental picture, showing the beauty of nature, humanity and sports.
In fact, every frame of the scene has been rehearsed thousands of times in the "big abacus" behind it.
In the past two years, Ding Gangyi, director of the Digital Performance and Simulation Technology Laboratory of Beijing Institute of Technology, led the virtual simulation team of Beijing Institute of Technology, and used an integrated service platform for intelligent creation, arrangement and performance to provide scientific and technological support for the opening ceremony of the Winter Olympics.
In Ding Gangyi's words, this platform is like the "abacus" in the planning of the opening ceremony.
The construction of smart venues is leading the direction of the construction of sports venues at home and abroad, and the Beijing Winter Olympics venues pay more attention to the use of advanced technology.
The National Speed Skating Hall "Ice Ribbon" is a new type of venue with a smart brain.
By establishing a digital twin and an intelligent integrated management platform, the data of many subsystems are brought together and managed centrally.
On this platform, the data update speed has been increased from seconds to milliseconds, contributing wisdom to the "fastest ice" on the "Ice Ribbon".
In addition to the use of carbon dioxide transcritical direct cooling system to make ice, the "Ice Ribbon" venue facilities also realize 3D visualization and hierarchical information browsing, and realize comprehensive intelligent management of venue operation data collection, trend research and judgment, early warning and analysis and decision-making.
Traffic management, intelligent driving, autonomous parking, unmanned retail vehicles... The 5G Internet of Vehicles at the Winter Olympics will make travel more efficient.
According to reports, by deploying 5G base stations, roadside units (RSUs) and edge computing servers, the traffic operation of the park is collected.
The collected data is fused with the data collected by the vehicle's own radar and camera to control the vehicle's operation after cloud computing.
Based on 5G, the interaction between the vehicle and the cloud can be realized in less than 10 milliseconds. Such a delay can enable the vehicle to respond quickly and ensure safe driving.
Also thanks to the application of smart technology, the National Aquatics Center has changed from "Water Cube" to "Ice Cube". Through the "water-ice conversion" detachable structure, it can realize the conversion of winter and summer usage scenarios.
The National Ski Jumping Center is the first large platform in the history of the Winter Olympics to use ice-assisted slides. During the construction process, an intelligent monitoring system for the temperature displacement of the ice surface of the ski-jumping slides was developed.
Zhong Bingshu, former president of the Capital Institute of Physical Education, said that from the perspective of hosting the Games, the Beijing Winter Olympics embodies world vision, international standards, Chinese characteristics, and high-level positioning, especially in key technologies, weather, and venue facilities. effect.
Embody an athlete-centred
Different from the Beijing Winter Olympics venues full of technology, the Winter Olympics Village shows more humanistic care to the athletes.
Multifunctional beds, smart restaurants, etc. make athletes shout "eat well and sleep well".
Intelligent services such as unmanned minibuses, unmanned retail, digital RMB payment, and a dedicated intelligent operation and maintenance management platform for the disabled make the Beijing Winter Olympics more convenient, efficient and safe.
According to the national key research and development plan "Science and Technology Winter Olympics" key special implementation plan, which includes not only the key technologies of the Winter Olympic Games, but also the key technologies of winter sports training and competition, the key technologies of public safety, global influence communication and wisdom The key technologies for watching the game, the construction of a green and smart comprehensive demonstration area, etc., will provide scientific and technological support for the Beijing Winter Olympics and Winter Paralympics.
"From the characteristics of special sports, the optimization of material selection technology to sports drag reduction, the application of wearable devices, etc., the preparation of the Winter Olympics has done a lot of research on the key technologies of athletes' winter sports training and competition. The promotion and application of all these technologies can greatly Improve training effects and competition monitoring capabilities." Zhong Bingshu said that from the perspective of participation, this also makes the Winter Olympics more exciting, and at the same time further promotes the opening of technology, which is in line with the IOC's "athlete-centered" concept.
It is understood that the original research on athletes was limited to the sports scientific research department itself, but the research on athletes at this Winter Olympics has been extended to different research fields and industries, including specialized research institutions, intelligent development enterprises, and others from different different majors in colleges and universities.
"Promoting athlete-centered research is to promote research and attention to people. This kind of research will play an important role in our future development of popular ice and snow sports and improvement of athletes' quality and ability." Zhong Bingshu said.
Sharing the excitement on and off the field
Based on digitalization, the Olympic Games are taking on a new splendor.
Thomas Bach, President of the International Olympic Committee, praised that the Beijing Winter Olympics has created history, allowing more people to experience the Olympic culture and splendor with an unprecedented level of digitalization.
The Beijing 2022 Winter Olympics will bring all-round and profound changes, showing the broad prospects for the application of technology to ice and snow sports.
Spectators in the stadium can enjoy different viewing experiences such as 360° viewing angle, 8K+VR box service, etc., and watch the game in real time.
Outside the venue, you can also enjoy a "cloud box"-like experience, bringing movie special effects such as super slow motion and panoramic viewing.
The Olympic Broadcasting Service (OBS) recently stated at a press conference that the Beijing Winter Olympics has become the Winter Olympics with the highest ratings so far, setting new records in terms of broadcast duration, technology, and content production methods.
The Beijing Winter Olympics also became the most-watched Winter Olympics on NBC's digital platform.
The application of technology has greatly facilitated the viewing of the game, reflecting the concept of sharing the Olympic Games.
One of the key points of sharing is to attract more young people and more spectators to participate in the Beijing Winter Olympics and learn about the Beijing Winter Olympics.
This depends on the breakthrough innovation and application demonstration of key technologies for smart viewing.
5G+4K and 8K technologies will help the Beijing Winter Olympics present wonderful games to the world.
For the first time in the history of the Winter Olympics, 3D playback technology was used in each competition event.
Some events also use virtual analysis technology.
Different from the traditional broadcasting method of the Olympic Games, the Beijing Winter Olympics will migrate the core information systems of the Olympic Games, such as event results, event broadcasting, and information release, to the cloud, and use the "Olympic Broadcasting Cloud" to broadcast to the world.
This makes remote production of content a reality, enabling timely transmission of signals.
Ianis Exarks, CEO of OBS, said in an interview a few days ago that it is precisely because China is so mature in broadcasting and telecommunications technology and industry that we have the opportunity to use these high technologies.
Each Olympic Games promotes the further development of event broadcasting technology and provides valuable experience for future sports events and activities.
The Beijing Winter Olympics uses technology to refresh the viewing experience, and those wonderful moments of the games will remain in people's memory together with the "Smart Winter Olympics", writing an immortal chapter in the Olympic history.
