epilogue
Through the above black technology, it is not difficult to see that the Olympic Games are not only a sports arena for athletes, but also a scientific and technological testing ground that represents the highest level in the world today.
Counting the previous Olympic Games, almost all of them carry the latest technology at that time. At the 1928 Amsterdam Olympic Games, high-speed cameras were first introduced, which were equipped with the top image processing technology of the time to assist referees to make more fair decisions by replaying images at a slow speed; at the 1936 Berlin Olympic Games, the first television broadcast was used to report the event, and people could sit in front of the big screen in the Olympic Village to watch the game; at the Munich Olympic Games in 1972, for the first time, a computer system was used to count the results of various competitions in just a few seconds.
The application of new technologies also gives Olympico more missions. When the time came to 2010, the IOC decided that in addition to promoting success in sport, the Olympics should also use new technologies to set new benchmarks for education, social inclusion and sustainable development.
That's when reducing costs, driving carbon neutrality, and leaving an Olympic legacy behind became more important issues. 2010 Vancouver Winter Olympics, refining 140,000 tons of electronic waste to cast medals, "Eye on the Hog" applied to curling projects to avoid misjudgment, design waste heat recovery system to reduce energy consumption; 2014 Sochi Winter Olympics, maintain 54Tb per second of ultra-large bandwidth transmission capacity during the event, after the game venue continues to be used for athletes training; 2018 Pyeongchang Winter Olympics, DRC-HUBO robot relay the Olympic torch, Gangneung Ice Hockey Center can become a new digital performance venue after the game.
The 2022 Beijing Winter Olympics, I believe that it will definitely hand over a copy of the "China Answer Sheet".
