The seven black technologies of Beijing Dongdongao shocked foreigners. Do you know what these seven black technologies are?

A big "black technology": the first live broadcast of CCTV unmanned sign language AI host.

Two "black technologies": traffic black technology

Since there are three competition areas in this Winter Olympics, in order to enable athletes and the media to reach other competition areas conveniently, safely and smoothly, China "tailored" the exclusive train for the Winter Olympics, and built the Fuxing bullet train line in a short time, with a speed of 350 kilometers per hour. In addition, the train has also realized the automatic operation of sections, which is the unmanned technology of high-speed trains. In addition, there is 5G technology in the train. In order to maintain a good Russian communication signal in the tunnel, our research team spent a year in an environment above 5000 meters above sea level. The developed 5G technology can adapt to various extreme environments. The train also has the only high-definition mobile studio in the world, and the host can also broadcast the event live in high-speed sports.

Three "Black Technologies": Infrastructure Black Technologies

In order to build high-tech green venues, all six venues used in the Beijing Winter Olympics have formed a set of black technologies with independent intellectual property rights, and 19 venues all use renewable energy such as wind power, solar energy and photovoltaic power generation. Many buildings are rebuilt on the original buildings, but it is not simply "magic", but adding new functions to the original functions. The stadium in the capital will undergo 30 venue changes, such as the National Aquatics Center "Water Cube", which is the first venue to realize the conversion from ice water to ice, and realize the sustainable utilization of water cube to ice. In addition, the venue of the curling track will also be assumed to be on the pool.

Four "black technologies": robot restaurants

What makes foreign athletes sigh is the robot restaurant with about 120 robots. There are no chefs and waiters here, and the "robot chef" in the fully transparent kitchen provides meals for thousands of people 24 hours a day in an orderly manner. Foreign media can't help but sigh when they see it: it will take 30 years to exceed it!

Five Black Technologies: Athletes' Equipment

Besides the athlete's down jacket that broke the Guinness World Record, there is also a Curling brush with its own memory. This kind of Curling brush can record the indicators of athletes, provide reference data for coaches to select athletes, and can also be used as a reference for athletes to continuously improve their performance. In addition, Dong 'ao Village also provides athletes with a "bed with memory function", which is not only comfortable, but also has massage function and "wake-up service".

Six "Black Technologies": Free Use of Snow

As the basis of hosting the Winter Olympics and successfully developing the ice and snow project, although China started late and the related technologies were monopolized by foreign countries, due to the continuous efforts of our scientific research team, China realized the real "freedom of using snow" in this Winter Olympics, and the technology of making ice-like snow trails was conquered by our scientific research team.

Seven "Black Technologies": Black Technologies for Epidemic Prevention

Against the background of COVID-19 epidemic, epidemic prevention can be said to be the most important link, and China's "scientific epidemic prevention policy" is not just talk. China has adopted a large number of "black technology" epidemic prevention equipment in this Winter Olympics, and hundreds of robots have made great contributions to this epidemic prevention.
