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

The scientific and technological innovations of the Beijing Winter Olympics will be carried out throughout the construction of venues, infrastructure, services and broadcasting technology. Artificial intelligence assistance systems and wind tunnel laboratories make athlete preparation more efficient. Through technological research, the Beijing Winter Olympics competition venues "technology model" full.

Shougang ski jump developed a tetrahedron module and tetrahedron connection node, to achieve different competitions track profile transformation. National Snowmobile and Sledding Center track length, large drop, more curves, through technological innovation to solve the track accuracy and temperature difference control problems ...... the current Winter Olympics short-track speed skating competition, the application of ultra-high-speed 4k track camera system makes the game more ornamental, but also more fair.

"This is an event of science and technology for sports development." Puyana, president of the Colombian-Chinese Friendship Association, said China's use of renewable energy in venue construction, transportation and other areas complemented technology and sports. The extensive use of technological elements in the construction of venues for the Beijing Winter Olympics will bring more convenience to participating athletes and help them play better during the games. National Speed Skating Hall, Wukesong Sports Center and other venues used carbon dioxide transcritical refrigeration system, the temperature difference between the ice surface is controlled within 0.5 degrees Celsius, the carbon emissions are close to zero; the venues use the integrated design of cooling and heating supply for recycling of cooling waste heat, energy efficiency by 30%-40%; for the first time in the history of the Olympic Games to achieve 100% green power supply for all venues, large number of Hydrogen cars are put into use ...... international sources believe that the Beijing Winter Olympics will reduce carbon emissions through scientific and technological means, which is of great significance in promoting environmental protection and green development. The Beijing Winter Olympics' "technology model" is not only reflected in the hardware facilities of the venues, but also in the improvement of service quality.

For example, 5g signal coverage to all venues and roads connecting the venues has provided a strong support for rich media dissemination methods; high-tech products and technologies with free viewpoints, cloud interconnection and other features have provided more choices for the audience to watch the event. In the main media center of the Beijing Winter Olympics, a huge screen attracts attention. Relying on cloud technology, people in different regions can realize immersive interaction on the screen. Not long ago, the International Olympic Committee President Bach through the technology with the center of the journalists "face to face" communication. Bach said that China's digital technology in the digital transformation of the Olympic Games has played an active role, cloud technology and other Olympic Games to reach a new high technical standards. "The current Winter Olympics has an unprecedented level of digitization, allowing more people to participate in the Olympic movement."
