The Beijing Winter Olympics is closing. High tech robots are impressive. Let's take stock of the black technology of the Winter Olympics!
At 20:00 on February 20, the 17 day Beijing Winter Olympic Games will end at the bird's nest of the National Stadium. The shock of the opening ceremony seems to be in front of us, and the upcoming closing ceremony will bring the same surprise to the audience, forming a narrative mode of "one continuous line" with the opening ceremony, presenting Chinese romance and "double Olympics" feelings.
Looking back on the whole winter Olympics, the beginning of science and technology has amazed the media all over the world. The press corps of well-known news networks such as Japan's sports bulletin and Asahi Shimbun interviewed the Winter Olympic Games and reported the Winter Olympic information in Beijing. They not only praised the warm service of the Winter Olympic volunteers, but also praised the high-tech facilities of the Olympic village. Robots shuttling back and forth in the venue of the Winter Olympic Games, the main media center, hotels and other places have attracted the attention of people from all over the world.
Today, we take stock of the seven cool black technologies of the Beijing Winter Olympic Games that moved foreigners. Which of these advanced technologies have you seen?
1. Live broadcast black Technology
In terms of live broadcasting, traditional broadcasting often requires a huge production team and funds, and a 4K broadcasting car alone needs up to 80 million. However, the advanced equipment used in the venues of the Winter Olympic Games is rarely seen. It has appeared in science fiction films, which is similar to the high freedom viewing effect of "bullet time".
This technology is called "360 degree VR technology". It can intelligently capture and track the high-speed moving targets of the whole venue, and use multiple panoramic cameras to play back the event 360 degrees, so that those "pickpockets" have nowhere to escape.
Another technology is called VSS, which is a digital twin venue simulation system. Technicians combine the real stadium with the Internet of things through modeling to provide a better immersive viewing experience for the audience. This is also the first time that China has used the self-developed free perspective technology, which can provide 4K UHD format broadcasting, and some important events will even use 8K format broadcasting.
In this way, unmanned real-time follow-up and broadcasting can provide convenience for media reporters who are affected by the epidemic and cannot visit the scene in person. For the staff, the broadcast only needs a photographer, a notebook, a 5g backpack weighing one kilogram and a camera to complete the broadcast of the whole winter Olympic Games.
For the audience, the live broadcast will be more shocking than watching the game on site. They only need to hold a 5g mobile phone to be their own guide and change the viewing position at any time. Coupled with 3D sound and VR technology, you won't miss every highlight moment in the event, as if you were on the scene.
Of course, the concept of wisdom is inseparable from the "digital man". In order to facilitate the disabled to watch the game, the first AI sign language anchor of CCTV has successfully left the circle, and let foreigners call China our future!
2. Intelligent transportation
As the Winter Olympic Games are in full swing, China's exclusive train tailored for the Winter Olympic Games has been officially launched. As there are three competition areas in the Beijing Winter Olympic Games, China has built the Fuxing bullet train route with a speed of 350 kilometers per hour in a short time according to the needs of athletes and the media, which can be reached as far as the stadium in an hour.
The Beijing Zhangjiakou Railway itself is the first railway line independently designed and built in China. Today, a hundred years later, this railway runs China's first driverless intelligent train, which is also China's first to complete the driverless function of high-speed railway trains all over the world.
What is worth mentioning is that in order to help the stable connection of the Winter Olympics on the communication network, the scientific research team experimented in the environment of more than 5000 meters above the altitude of Mount Everest for one year, developed 5g technology that can adapt to various extreme environments and applied it to the train.
The train will pass through 13 tunnels, two sound barrier areas and bridges in the whole journey. You should know that in this environment, it is difficult for the signal to maintain a stable connection, especially the high-speed moving state with a speed of 350 kilometers per hour. But with the blessing of Huawei 5g technology, it will be difficult for you to think without signal on this train.
In addition, the train is also equipped with the world's only 5g ultra clear mobile studio, which allows the host to broadcast the Winter Olympic Games at high speed. In these carriages, each seat of the athletes is equipped with its own touch screen, tablet and wireless charging board.
This series of advanced technologies undoubtedly reflects China's top technology crystallization in the world of high-speed rail, and let people all over the world see China's strong strength in the field of high-speed rail again.
To attract global attention is to reduce the spread of the epidemic. In Shougang Park of Beijing Winter Olympic Games, more than 100 driverless vehicles have been put into trial operation before the opening of the Winter Olympic Games, and the cumulative test mileage has reached 150000 kilometers.
However, after the driverless accident of the Tokyo Olympic Games, driverless cars in the Winter Olympic Games have once again become the focus of public opinion. At that time, in the Tokyo Olympic Village, a Toyota driverless car collided with a Japanese Paralympic athlete, causing the athlete to be injured and regret to withdraw from the race.
3. Infrastructure black Technology
In order to build green and environmentally friendly high-tech venues, the six venues used in this winter Olympic Games have formed a set of black technology with independent intellectual property rights. A total of 19 venues, 100% of which use green renewable energy such as wind power, solar energy and photovoltaic power generation, which has reached the extreme on the road of sustainable development.
In this winter Olympic Games, many buildings are transformed on the original basic buildings. However, this transformation is not a simple transformation, but to retain the original use functions and add new functions during the construction process.
During the Winter Olympics, the stadium in the capital will undergo 30 venue changes, and set many world firsts. You can't imagine how they can make a perfect conversion!
For example, the water cube of the National Swimming Center, which is the first venue to realize ice water conversion, will also become the first venue in the world to set up a curling track on the swimming pool, and has the conditions to host ice and water events at the same time; The gorgeous cross dressing from water cube to ice cube has become a model for the sustainable utilization of Olympic venues.
In addition, Wukesong Sports Center can not only hold basketball matches, but also curling matches, and it takes only six hours to switch from ice hockey to basketball.

In fact, it is not that there are no new venues. The "ice ribbon" located on the central axis of Beijing is the only new ice event competition venue in China's Beijing Winter Olympic Games, which reflects the highest level of China's construction industry and has realized multiple innovations on the road of sustainable development.
The first new ice sports venue for the Winter Olympics
The 12000 square meter all ice speed skating hall is currently the largest ice hall in Asia. In order to focus on carbon neutralization, the ice ribbon and the capital gymnasium are the first carbon dioxide refrigerants with zero carbon emission.
According to the experience of initial use at the end of 2021, the innovative technologies that do not destroy the ozone layer used in the four ice venues have reduced carbon emissions by 900 tons. Ice ribbon uses this technology to use the waste heat generated in the athletes' domestic hot water. It can save 2 million kwh of electricity a year, which is also an unprecedented 100% green power in the history of the Olympic Games.

In the Zhangjiakou competition area, the "xueruyi" big jump platform of the national ski jumping center excels in nature, creating the competition venue with the largest amount of work and the highest technical difficulty among the ancient poplar venues. It is also a ski big jump platform that can be permanently retained at present.
It is located on the mountain slope with a drop of 160 meters, creating a lot of world records. During the event, the world's fastest slope inclined elevator will be put into use. In any way, xueruyi is the most advanced ski jumping venue.

In the face of the chain challenges brought by the epidemic, China can also make preparations for the game in an environmentally friendly way, so that the world can see the strength of China's speed.
4、robot restaurant

Many foreign journalists came to the restaurant for the Winter Olympics. There are no chefs and waiters here. In the fully transparent kitchen, some special chefs will work in an orderly manner, and can complete the preparation of rich Chinese food, Western food and cocktails, and the integration of cooking, packaging and serving.
It is understood that there are about 120 catering robots in the whole restaurant, which can serve thousands of people 24 hours at the same time. There is no need to contact people or queue up hard. The novel and unique robot restaurant can bring the best experience to athletes, which makes many foreign media reporters dumbfounded.

5. Athlete equipment black Technology
In addition to the athletes' down jacket that broke the Guinness world record, the curling brush with its own memory function is also a great artifact. It will record various indicators of athletes, and then serve as the standard for coaches to select players, and even help players improve their performance and skills.

In addition, the athletes' apartment in the Winter Olympic village is equipped with a bed with memory function. Unlike the paper bed of the Tokyo Olympic Games, the mattress is also equipped with a sensor, which can sense even a feather falling. It also integrates massage, alarm clock and other functions. The height of the bed can also be adjusted according to the remote control. Every piece of hardware can kill the Tokyo Olympic Games.

6. Freedom with snow
Since there were few international events held in China in the early years, ice and snow research started late. In the previous winter Olympic Games, snow making, hail snow and snow removal are the key to ensure the smooth progress of skiing competitive events.
Freedom with snow
But for a long time, this technology has been monopolized by foreign countries, and their research team will only tell us that the quality is not up to standard, and they are silent on the technical level.
In order to ensure that China can provide good competition experience for athletes all over the world, Chinese researchers worked hard. Finally, under different climatic environments, the track production technology of ice snow has been overcome, and it has achieved to provide a green and efficient template for the post Winter Olympic era.

8. Epidemic prevention robot
All the foreigners who came to the Winter Olympic venues were shocked. He couldn't believe that China's epidemic prevention measures could reach the extreme. No matter where it is, hundreds of robots undertake services such as epidemic prevention and control, security, patrol, logistics, transmission, translation and even sign language.
It can also prove to some foreign media that scientific epidemic prevention is not just a slogan, let alone a gimmick. In addition, a small armpit band aid also plays an important role.

The report of the media press corps also specifically mentioned the intimate "media material package", which is specially prepared for media workers. "This information package feels particularly heavy, because the information package contains not only the introduction manuals, commemorative badges, notebooks, power converters of various venues, but also cold proof and thermal insulation kettles, hats and other thermal insulation facilities. These materials are very important to us."
From the first day of the torch relay of the Beijing Winter Olympic Games, the amazing "robot underwater relay of the Winter Olympic torch" began. The comprehensive application of scientific and technological innovation achievements made it so different. The "scientific and technological Winter Olympic Games" that demonstrated national strength also showed the world a modern and rapidly developing China.
