CCTV News (News Network): During the Beijing Winter Olympics, from the opening ceremony to the construction of venues, from the organization of events to the protection of athletes, a series of high-tech applications have made the "Winter Olympics of Science and Technology" a Chinese force shining in the world.
In the past few days, freestyle skiing has attracted the attention of the world, and everyone is marveling at the superb skills of the athletes, but also praising the Shougang Ski Jumping Platform with the reputation of "Snow Flying". The big jumping platform uses a unique modular design and special steel, while cleverly using Shougang's original factory buildings and industrial buildings for transformation, Chinese wisdom makes the perfect integration of industrial heritage and modern technology.
The high-tech content is reflected in all aspects of the construction of the venue. At the Capital Stadium, co2 transcritical direct cooling technology is used for the first time, which greatly reduces the carbon emissions of the refrigeration process. At the National Speed Skating Hall, nearly 12,000 square meters of ice surface adopts sub-module control technology, which can save 1.8 million kWh of electricity a year.
Science and technology empower the Winter Olympics, and the Winter Olympics press the "acceleration button" for the transformation of scientific and technological achievements. For the first time, the China Central Radio and Television Corporation independently developed an ultra-high-speed 4K orbital camera with a maximum speed of 90 kilometers per hour, "Cheetah", so that the audience does not miss every wonderful moment. Tsinghua University's intelligent heating system, Beijing Institute of Technology's intelligent training system, HIT curling robot, etc., dozens of universities and research institutes joined the action plan of the "Winter Olympics of Science and Technology". At the opening ceremony of the Winter Olympic Games, the "ice and snow rings" that amazed the world weighed 3.2 tons and was only 35 centimeters thick, which was the structural design technology of the rocket.
Chinese science and technology, Chinese manufacturing has become an important boost to the development of ice and snow sports. Venue simulation system, mobile Internet "minute-level, 100-meter- level" meteorological forecast, winter sports clothing equipment, the first domestic snowmobile, the first use of hydrogen fuel winter Olympic torch, a batch of scientific and technological achievements to achieve breakthroughs from scratch.
