Technology is an indispensable support for the Beijing Winter Olympics and Paralympics.
On the basis of traditional Olympic technical services, there will be new technical applications in every Olympic event.
Yu Hong, director of the Technology Department of the Beijing Winter Olympics Organizing Committee, mentioned the above at the press conference on the 18th.
A batch of new technologies are applied in the test competition
The Beijing Winter Olympics Organizing Committee focuses on the actual needs of organizing and hosting events. The implementation plan includes new technical requirements in terms of infrastructure, green environmental protection, smart services, broadcast technology, and artificial intelligence.
Yu Hong said that a number of new technologies have been tested and applied in this year's test competition, which strongly supports the preparations for the Winter Olympics.
5G signal covers all venues and roads connecting venues
Yu Hong said that for the actual application of new technologies in the Winter Olympics, the Beijing Winter Olympics Organizing Committee first paid attention to the venues, which are the basic conditions for hosting the Olympics:
The only newly-built venue for the Beijing Winter Olympics in downtown Beijing is the National Speed Skating Stadium, known as the "Ice Ribbon".
This venue uses the world's largest single-layer two-way orthogonal saddle-shaped cable net roof, and the steel consumption is only one-fourth of the traditional roof.
The national snowmobile sled center known as "Snow Youlong" adopts "millimeter-level" hyperboloid concrete spraying and finishing molding technology, and the 1.9-kilometer track is sprayed and poured at one time.
The National Aquatics Center has been converted from the Water Cube to the "Ice Cube", using assembly-type quick disassembly and leveling dynamic monitoring technology to complete the "water-ice" site conversion within 20 days.
Shougang Ski Jump has developed regular tetrahedral modules and regular tetrahedral connection nodes to realize the conversion of track profiles in different competitions.
Yu Hong mentioned that the use of the Internet of Things and artificial intelligence technology is building the Bird's Nest into a digital, low-carbon, and smart stadium.
In addition, the 5G signal that has received much attention covers all venues and the roads connecting the venues, including the high-speed Beijing-Zhangjiakou high-speed rail, which also has stable and continuous 5G signal coverage.
This provides necessary network connections for new application scenarios such as ultra-high-definition video and various intelligent services.
Able to achieve "hundred-meter-level, minute-level" precise weather forecast
Yu Hong said that outdoor events such as alpine skiing, ski jumping, and aerials at the Beijing Winter Olympics require very accurate weather forecasts. The weather conditions determine whether certain events start on time or need to be postponed.
The Winter Olympics weather forecasting system can realize "hundred-meter-level, minute-level" precise weather forecasting.
In the February test event, according to the weather forecast, the schedule of 12 games and training were adjusted.
More than 700 hydrogen fuel buses will be invested to provide transportation service guarantee
She said that in order to achieve the carbon neutral goal of the Beijing Winter Olympics, through the Zhangbei flexible DC grid project, green electricity produced by wind and solar energy in the Zhangbei area will be imported into Beijing. During the competition, all venues in the Beijing Winter Olympics will achieve 100%. Green power supply.
The National Speed Skating Stadium, Wukesong Sports Center and other Winter Olympic venues use a carbon dioxide transcritical refrigeration system, the temperature difference of the ice surface is controlled within 0.5 ℃, and the carbon emissions are close to zero. This technology is widely used in the Winter Olympics. For the first time in the history of the Olympics, at the same time, the integrated design of combined cooling and heating was used to recover and reuse the cooling waste heat, which increased energy efficiency by 30-40%.
80 hydrogen fuel cell vehicles were tested in the Zhangjiakou competition area. During the competition, more than 700 hydrogen fuel cell vehicles will be deployed in Yanqing and Zhangjiakou to provide transportation services; the trial-produced hydrogen fuel cell emergency power generation vehicle will replace diesel power generation vehicles. The National Speed Skating Stadium and the National Alpine Ski Center are available for testing;
In addition, all the relay torches in the Beijing Winter Olympics will use hydrogen fuel.
Degradable tableware produced from renewable resources such as corn, potato and straw as raw materials will replace plastic products to provide relevant services for the Winter Olympics.
Media reporters can achieve cross-space interviews
Broadcasting is indispensable in the modern Olympics. It allows Olympic fans all over the world to feel the wonderful performance of athletes no matter where they are.
Due to the 5G signal coverage, there is also a new model for rebroadcasting.
Yu Hong mentioned that on the basis of the test game, the cloud broadcast technology will cooperate with OBS to provide bullet-making time in the "Slope Obstacle Skills of Yunding Ski Resort" project; cloud broadcast 5G backpack can directly collect front-end equipment The video signal of the company was uploaded to the cloud platform in real time; the 8K high-definition broadcast vehicle was recorded and broadcasted at the short track speed skating event held in October, which lasted 22 hours.
In addition, in the mixed interview area, a remote control camera system is used to realize cross-space interviews by media reporters.
Test applications have been available for the April test event. During the October test event, athletes from South Korea, the Netherlands, China and other countries received remote interviews from the media through the cloud interview system; the Beijing Winter Olympics press conference video service system (InfoAV), The game will add audio and video content for news releases on the basis of traditional text information services.
Speech recognition and translation technology can assist communication without barriers
Yu Hong said that the organizers of the Olympic Games have also felt the subtle changes in their work patterns in the application of new technologies.
Three-dimensional simulation of venues can be used for online business flow, regional planning and design, and simulation deployment of media camera positions. Online surveys and online collaborative design can be realized, not only for technical support under the epidemic, but also for improvement under normal conditions. Technical means of work efficiency.
The remote simultaneous interpretation function of the video conference provides a new solution for remote international conferences under the epidemic; the intelligent conference translation system supports multilingual real-time voice transcription and multilingual translation; voice recognition and translation technology can assist communication without barriers.
Viewers can see the 8K game screen on TV
Yu Hong mentioned that the free perspective allows the audience to freely choose the viewing angle and time on the screen; the stadium panoramic picture guide can browse the stadium online; the indoor accurate navigation helps the audience quickly reach the stadium seating area.
In addition, the upcoming 8K channel will give viewers the opportunity to watch 8K game images on TV during the game, and also have the opportunity to see ultra-high-definition images on 8K terminals in Winter Olympic venues, city squares and other places.
The mobile diagnosis and treatment vehicle for maxillofacial trauma can timely diagnose and treat athletes' injuries on the spot.
