In the recently concluded "Meet in Beijing" ice hockey domestic test activities, a series of scientific and technological innovations debut in the National Stadium: the field of large screens can realize real-time interaction with the audience; through the cell phone can be completed indoor high-precision navigation of the arena; the field of the "mobile diagnostic and treatment vehicle" can be completed within five minutes, the "mobile diagnostic and treatment vehicle" can be completed within five minutes, the "mobile diagnostic and treatment vehicle" can be completed within five minutes. "can be completed within five minutes of maxillofacial trauma on-site imaging and artificial intelligence diagnosis, to enhance the efficiency of medical services at the time of the game ...... from the game to watch the game, scientific and technological innovations everywhere highlighting the "science and technology of the Winter Olympics" undertones.
From the beginning of the successful bid for the Winter Olympics, "science and technology winter Olympics" has become one of the key words in the preparation of the Winter Olympics. "Looking back at the work of science and technology Winter Olympics in the past few years, it can be summarized in nine words: there is planning, there are results, there are expectations." Yu Hong, minister of the technical department of the Beijing Winter Olympic Organizing Committee, said at a news conference on November 18 on the Beijing Winter Olympic Organizing Committee's Science and Technology Winter Olympics, looking forward to the highlights, technology-rich Beijing Winter Olympics.
"Science and Technology Winter Olympics (2022) Action Plan" centered around eight aspects, to help the Winter Olympics preparatory work
As early as the beginning of the Winter Olympics preparations, the Ministry of Science and Technology in conjunction with the Beijing Municipal Government, the Hebei Provincial Government, the Beijing Organizing Committee for the Winter Olympics, the State General Administration of Sports and other research and development of the "science and technology winter Olympics (2022) Action Plan" around the "zero-emission energy, Green travel, 5G **** enjoy, intelligent spectators, sports technology, clean environment, safe games, international cooperation" and other 8 aspects of work, through a systematic layout of scientific and technological winter Olympics key tasks, to help the winter Olympics preparatory work.
"The actual application of new technologies in the Beijing Winter Olympics, we first focus on the venues, which is the basic conditions for organizing the Olympic Games." Yu Hong said, through technological research, each competition venue has a full "technology paradigm". As the only new ice arena in Beijing, the National Speed Skating Center uses the world's largest single-layer span of two-way orthogonal saddle-shaped cable network roof, the amount of steel is only 1/4 of the traditional roof; National Swimming Center from the "Water Cube" into the "Ice Cube", the application of the The National Swimming Center is transformed from "Water Cube" to "Ice Cube" by applying the assembly fast disassembly and leveling dynamic monitoring technology, and the venue conversion from "water to ice" can be completed within 20 days; Shougang Ski Jump has developed a tetrahedron module and tetrahedron connecting nodes, which can realize the transformation of track profiles of different competitions.
Wu Yuanbin, director of the Ministry of Science and Technology's Social Development Science and Technology Department, said the establishment of the national key research and development program "science and technology of the Winter Olympics" key special projects, venue planning, construction, operation and maintenance of key technologies as one of the key tasks for the layout, to solve the snowmobile bobsled track, the National Ski Jumping Center, the National Alpine Skiing Center and the National Speed Skating Pavilion and other venues design, design, construction and operation of key technologies, to solve the problem. It has solved technical problems in the design, construction and operation and maintenance of snowmobile bobsled track, national ski jumping center, national alpine skiing center and national speed skating hall, and supported the transformation of the National Stadium and the National Swimming Center for ice and water conversion and other venues.
The National Ski Jumping Center in Zhangjiakou and the Shougang Ski Jump in Beijing applied for the first time the competitive artificial profile track design method and construction key technology in line with international standards, which is the first of its kind in China. The national snowmobile and bobsled track has a large length, large drop and many curves, and through technological innovation, it has solved the problems of track precision and temperature difference control, and for the first time, it realizes 360-degree slalom curves to be molded by one-time jetting, and at the same time, it can satisfy the anti-seismic requirements of the high intensity area in Yanqing.
