Why is "Technology Winter Olympics" the main feature of the 2022 Beijing Winter Olympics?

Scientific and technological innovation of Beijing Winter Olympics runs through all aspects such as venue construction, infrastructure, service guarantee and broadcasting technology. Artificial intelligence auxiliary system and wind tunnel laboratory make athletes prepare for war more efficiently. Through technical research, the venues of Beijing Winter Olympics are full of "sense of science and technology".

Regular tetrahedron modules and regular tetrahedron connection nodes were developed in Shougang ski platform, which realized the track profile transformation in different competitions. The national snowmobile sled center has a long track, a large drop and many bends. Through technological innovation, the problems of track accuracy and temperature difference control have been solved ... The application of ultra-high-speed 4k track camera system in the short track speed skating competition of this Winter Olympics makes the competition more ornamental and fairer.

"This is a grand event for science and technology to promote sports development." Pouyanne, president of the Colombian-China Friendship Association, said that China has applied renewable energy in the fields of venue construction, transportation and so on, and science and technology and sports complement each other. The wide application of scientific and technological elements in the construction of the Beijing Winter Olympics venues has brought more convenience to the participating athletes and helped them to better play their level in the competition. The National Speed Skating Hall, Wukesong Sports Center and other venues have adopted the carbon dioxide transcritical refrigeration system, and the ice temperature difference is controlled within 0.5 degrees Celsius, and the carbon emission is close to zero. The stadium adopts the integrated design of cooling, heating and supply, recovers the residual heat of refrigeration, and improves the energy efficiency by 30%-40%; For the first time in the history of the Olympic Games, all venues 100% green power supply was realized, and a large number of hydrogen-powered vehicles were put into use ... International people believe that reducing carbon emissions through scientific and technological means in the Beijing Winter Olympics is of great significance to promoting environmental protection and green development. The "scientific and technological model" of Beijing Winter Olympics is not only reflected in the hardware facilities of venues, but also in the improvement of service quality.

For example, 5g signals cover all venues and roads connecting venues, which provides strong support for enriching media communication methods; High-tech products and technologies with the characteristics of free viewing angle and cloud interconnection provide more choices for the audience to watch the game. In the main media center of Beijing Winter Olympics, a huge screen is eye-catching. Relying on cloud technology, people from different regions can realize immersive interaction on the screen. Not long ago, IOC President Bach used this technology to communicate face to face with reporters at the center. Bach said that China's digital technology has played an active role in the digital transformation of the Olympic Games, and cloud technology has raised the technical standards of the Olympic Games to a new height. "The digital level of this Winter Olympics is unprecedented, allowing more people to participate in the Olympic movement."
