More than 200 technologies were tested in the Beijing Winter Olympics. How powerful is the scientific and technological force behind the Winter Olympics?

The Beijing Winter Olympics is full of black technology, which makes more and more people marvel at the speed and strength of China's scientific and technological progress, and the scientific and technological elements have become a highlight. Then let's take a look at the black technology used in this Winter Olympics. The first is the robot restaurant. In this smart restaurant in Dong 'ao Village, all the cooking and serving are done by robots. After the mechanical arm completes the production procedures such as cooking and wine mixing, another device delivers the dishes to customers, which not only shows the technical strength of robots in China, but also reduces the contact between people during the epidemic, killing two birds with one stone.

The opening ceremony of Beijing Winter Olympics has ended. At present, the Beijing Winter Olympics is being held fiercely. It can be seen from previous opening ceremonies and competitions that there are many high technologies in this Winter Olympics. What specific high technologies have been embodied in this Winter Olympics? In order to shorten the time for athletes to reach the competition area, the unmanned train built the Fuxing EMU line with a speed of 350 kilometers per hour. It is the first unmanned intelligent train in China, which can reach the farthest competition area within one hour, saving energy.

The staff calculated that compared with the driver's manual driving, Zhangjiakou to Beijing can save energy by 7%. The opening ceremony of the Winter Olympics was held on February 4th. The opening ceremony was held in the Bird's Nest. There was a lot of romance and black technology at the opening ceremony. For example, the performance of the opening ceremony was presented in the Bird's Nest with a large number of digital performances and simulation techniques, which also gave the audience an empty inspiration, but it was romantic. Moreover, in this opening ceremony, 2022 drones were used. These drones turned into snowflakes in the sky and then formed a melting ice mound.

Through the changes of these lights, the audience saw a 3D feeling. Non-hidden ultra-high speed 4K tracking camera system. In order to let spectators and referees watch the game more intuitively, the Beijing Winter Olympics adopted 360-degree shooting technology, which can shoot 4K ultra-high-definition pictures at a speed of 70 kilometers per hour. This system is also called? Cheetah? . This system can easily keep up with the athletes' high-speed movement, and shoot the game pictures in 360 degrees without dead ends. Especially in skiing events, the live broadcast made me really feel the black technology of the ultra-high-speed 4K track camera system.
