[Explanation] Technology is an indispensable support for the Beijing 2022 Winter Olympics and Paralympics.
On November 18th, the Beijing Winter Olympics Organizing Committee held a press conference.
Yu Hong, director of the Technology Department of the Beijing Winter Olympics Organizing Committee, said that new technologies have been fully utilized in the construction of the Winter Olympics venues.
[Concurrent] Yu Hong, Director of Technology Department, Beijing Winter Olympics Organizing Committee
The national snowmobile sled center called "Snow Dragon" 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 transformed 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.
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.
[Explanation] Currently, 5G signals have covered all Winter Olympic venues and connecting roads.
Yu Hong said that during the Winter Olympics, 5G will provide technical support in multiple scenarios.
[Concurrent] Yu Hong, Director of Technology Department, Beijing Winter Olympics Organizing Committee
From Beijing to Zhangjiakou, 5G signal coverage is achieved on the high-speed rail, and it is relatively stable and continuous.
Cloud broadcast, then the core is actually the audio and video signals collected by the front end, which can pass through the 5G backpack, which is actually equivalent to a small base station, which can be directly sent to my cloud.
The signals of our on-site diagnosis and treatment and medical diagnosis can also be transmitted to the background through the 5G individual soldier system and communication system in real time.
The transmission of weather data is currently based on our 5G signal.
In fact, with regard to 5G communication base stations, it has already withstood a number of challenges from severe cold and strong winds.
It is reported that we have all built to an altitude of more than 5,000 meters, and supported the 5G signal coverage of the Mount Everest Observation Deck and Camp 1, and supported the live broadcast of the summit.
[Explanation] In addition, green is also one of the goals of this Winter Olympics.
During the event, all venues for the Beijing Winter Olympics will achieve 100% green power supply, and all domestic relay torches will use hydrogen fuel.
[Concurrent] Yu Hong, Director of Technology Department, Beijing Winter Olympics Organizing Committee
The relay torch in the Beijing Winter Olympics will all 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.
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, the integrated design of combined cooling and heating was used to recycle the cooling waste heat, which increased energy efficiency by 30-40%.
