China Daily, February 11 (Reporter Sun Xiaochen) The Beijing Winter Olympics, which are currently in full swing, not only let us see the cool and heroic posture of athletes from all over the world on the ice and snow field, but also spread China's high technology all over the world. The black technology of the Beijing Winter Olympics can be described as ubiquitous, meticulous to every corner of food, clothing, housing and transportation.
At the security inspection and epidemic prevention sites of the Winter Olympic Village and various competition venues, devices with automatic identification document information and automatic temperature measurement provide convenient and rapid service guarantee for athletes from all over the world. Although the athletes of the ice and snow event are mostly "fully armed" when they enter the field, wearing hats, masks and even protective gear, and sometimes only showing their eyes, the field device can identify and display their photos and identity information on the display in just 1 second, making the athletes exclaim: "Oh my God, how did it do it?" ”
The smart restaurant of the Winter Olympic venue has also impressed many well-informed foreign journalists, and the large canteen of thousands of square meters has basically no chef, and after ordering, from ordering, stir-frying, and serving food are all completed by automated equipment and robots. The kitchen is fully transparent, the dishes are diverse, whether it is Chinese stir-fry, rice, dumplings, noodles or Western-style burgers, pasta, what you want to eat casually, do it on demand, a moment of kung fu, the robot will do a good job of food, directly to the table, to achieve zero contact between people, epidemic prevention work to the extreme. Foreign journalists can't take care of food, pick up the camera and grab a photo, release the media for the first time, and let the world feel The Chinese technology. It is much more than that that foreign journalists applaud, and the hard-core technology that supports the efficient operation of the Winter Olympics has really impressed them.
The three divisions of Beijing, Yanqing and Zhangjiakou are all connected by high-speed rail. The speed of the Winter Olympic high-speed rail is as high as 350 kilometers per hour, and the 5G network is fully covered in the carriage, even if the high-speed rail runs at the highest speed, the 5G network signal is still stable, and it will not be stuck at all while watching the game while sitting on the car. The world problem of signal stability in the high-speed rail state has been easily solved by China. Through 5G technology, China's high-speed rail has also realized driverless technology.
What is the most important thing about the Winter Olympics? Ice and snow, of course. Hosting a world-class event like the Winter Olympics is obviously not enough to rely on natural ice and snow alone, especially in the relatively dry climate around Beijing. However, natural snowfall is greatly affected by the climate, and the dry humidity and hardness cannot directly meet the technical requirements of the winter Olympic slope laying. To ensure the smooth and fair progress of skiing, high-quality and stable ski slopes are indispensable. Through the most modern artificial snowmaking technology and equipment, the Beijing Winter Olympics realized that all snow sports tracks are paved with artificial snow with controllable characteristics. The composition of this snow is exactly the same as natural snow, the most important thing is that it is more stable than natural snow, dry humidity and dosage can be intelligently controlled, the water consumption and manufacturing cost are relatively low, and non-toxic and harmless, people can enjoy close contact with it, snow meltwater can be harmlessly recycled after the game.
China's carbon dioxide rapid icemaking technology is the highlight of the venue facilities of this Winter Olympic Games. The newly built "Ice Ribbon" National Speed Skating Hall has the largest 12,000 square meters of ice surface in Asia, through the use of carbon dioxide transcritical refrigeration technology to achieve zero carbon emissions of the track ice, China's ice making program whether it is comprehensive energy efficiency or ice surface temperature difference has reached the international advanced level, to the athletes to bring soft and hardness uniform and stable high-quality ice surface, since the start of the speed skating project on a number of Olympic records refreshed, but also proved the quality of the "Ice Ribbon" ice surface.
The shocking visual effect of the opening ceremony of the Beijing Winter Olympics is also the result of the application of various scientific and technological means. The most classic moment of the full performance, the effect of the Olympic rings breaking through the ice is amazing: it will not really be carved on the spot, right? In fact, the ice bricks of the entire frozen five rings are a huge LED special-shaped screen, up to 20 meters long and weighing 3 tons, which can be said to be a perfect combination of science and technology and beauty. The waterfall flowing down the 8K screen makes people feel the shock of the water of the Yellow River in the sky; the "quicksand" that follows the actor's footsteps is also a lighting effect realized in real time by AI motion capture. The opening ceremony of the Beijing Winter Olympics left many unforgettable moments. Digital technology and Chinese aesthetics reflect each other to form this simple, aesthetic and futuristic event.
With science and technology as the medium, the opening ceremony of the Winter Olympics presented a dazzling and colorful aesthetic feast, and we had to admire the artistic talent of director Zhang Yimou. However, for the reporters in front, it is not easy to accurately capture such a rapidly changing color and pass it to the audience at the first time, which used to require a lot of professional and bulky equipment and the collaboration of many people to complete.
With the latest development of personal mobile communication equipment and the increase in demand for social media content, the media recording the wonderful moments of the Winter Olympics have become all-round reporters, taking photos, videos, recordings and so on. Fortunately, thanks to the advancement of science and technology, the reporters in front only need a mobile phone to complete some work such as taking pictures, videos, recordings, editing, and publishing. The Real Me GT2 Pro mobile phone, which was tried on the front line of the Winter Olympics coverage this time, has become a weapon for many media reports on the Winter Olympics with excellent camera and recording functions. In the highly anticipated opening ceremony scene, cool lighting changes on the camera requirements are very high, the Real Me GT2 Pro uses Sony IMX766 ultra-large bottom sensor, can provide higher dynamic range, the picture can have better color performance, the opening ceremony site fireworks and lights intertwined with brilliant colors can be perfectly displayed. The full-scene low-light imaging system is equipped to ensure that clear and dazzling photos can be taken at night. The blazing focus feature, combined with OIS + EIS dual stabilization technology, makes it easy to lock in high-speed motion, helping to capture moments of speed skating and alpine skiing on the spot. The new self-developed ProLight super-sensitive technology brings super noise reduction capabilities, even if the opening ceremony scene is low-light shooting, it can ensure a balanced detail performance of highlights and shadows. In addition, the world's first fisheye mode can bring shocking visual impact, which is very helpful for timely posting fun and interesting video content on social media.
Through the combination of science and technology and humanities, the Beijing Winter Olympics have demonstrated to the world China's great power strength and demeanor, and also made each of us Chinese deeply feel the strength of the country. At the opening ceremony of the Beijing Winter Olympics and the preparation and operation of the entire event, it can be seen that various digital technologies such as artificial intelligence, cloud computing, and digital twin technologies have been applied on a large scale. This world-renowned Olympic event is carrying the scientific and technological power behind it to "go to the future together".
