Xie Jun: Turning the Winter Olympics into a reality that everyone can experience

Short-track speed skating Olympic champion Yang Yang and women's chess world champion Xie Jun will actually come together, all because of the "Science and Technology Winter Olympics" key special project "ice and snow sports promotion and popularization of key technology product research and development and demonstration". However, the identities of the two champions have changed now, Xie Jun is the deputy dean in charge of scientific research at the Capital Institute of Physical Education and the person in charge of the project, and Yang Yang is the head of the project participating units.

It is understood that the project includes 5 sub-topics, which involve ice rink technology, simulation equipment, science popularization platform, sports promotion and mutual assistance between science and technology and sports.

What's the content? Xie Jun sold a guanzi: "More wonderful, you can go to the China Science and Technology Museum 'Science and Technology Winter Olympics' theme exhibition to find." "With a display area of about 2,000 square meters, the audience can not only watch, but also experience the fun of ice and snow and feel the atmosphere of the Olympic Games." With the blessing of modern technical means such as 5G, 4K, VR, etc., the 15 projects involved in the Winter Olympics can be experienced personally. ”

Behind the project that ordinary people can't understand the name into a reality that everyone can understand and experience is the team's nearly 2 years of cooperation and silent efforts. Even the elite team will encounter difficulties in the process of doing projects, and the most difficult one is how to make the story of the Winter Olympics vivid and let more people participate.

"New" is the trick to breaking the problem. For example, new materials - the project project undertaking unit Beijing Institute of Technology researched and developed "ice and snow gel" and other new materials to build ice sculpture jewelry, ice and snow big jump platform and other venue buildings, so that small audiences are addicted. There are also new technologies – the study of key technologies and the development of Volkswagen simulation ice and snow sports equipment for mobile removable artificial refrigeration ice rinks. Xie Jun said that experience is the best education. Every Winter Olympic project on display, the audience can try it. This requires that the flat land be made of "snow" and "ice", and even "mountains".

In order to create a mobile, removable artificially cooled ice rink, the team developed a 6-meter-long and 1-meter-wide ice board. Each ice plate is equipped with temperature, humidity and other sensor devices. These "small" ice plates can be assembled quickly, and can also achieve full-time rink monitoring and intelligent management. Xie Jun said, "After repeated training, it only takes 46 hours for the team to build a standard mobile detachable artificial refrigeration ice rink that is 60 meters long and 30 meters wide. Not only that, the recycling rate of ice rinks has reached more than 98%, which is suitable for more than 5 kinds of ice sports. ”

The volkswagen simulation ice and snow sports equipment developed by the team is an environmentally friendly and low-cost ice board and snow grass, which can be used in different environmental scenarios such as schools, communities, shopping malls, gyms, etc. The sense of sports experience of skiing and skating can be realized, "For the southern regions and urban residents with a hot climate, the use of this equipment can more easily experience the charm of ice and snow sports."

Future projects will give more answers. Xie Jun said that one of the project tasks is to build a youth ice and snow knowledge innovation platform, the current implementation of the plan is to rely on the national science and technology museum professional authority network to build ice and snow science dissemination chain, while integrating into universities, high-tech enterprises and related social resources to build ice and snow sports science popularization platform, to create a physical ice and snow sports science museum, mobile ice and snow sports science museum, digital ice and snow sports science museum, virtual ice and snow sports science museum, the formation of a "four-in-one" ice and snow sports science popularization system. "After the exhibition, the science exhibition will also tour the country, and will also launch a science caravan to let the Winter Olympic story go to the township and give wings to more children's scientific and technological dreams and sports dreams."

Technology helps the Winter Olympics, and many Beijing universities are now in action. Indoor simulation of "alpine skiing", corrosion-resistant steel applied to venues, and high-level automatic driving computing platform Behind each project, it reflects the concept of scientific and technological innovation of universities to seek development in services.

According to the "Action Plan for the Innovative Development of Scientific Research in Beijing Universities (2022-2024)", the "science and technology dream" of Beijing universities has a small goal: by the end of 2024, basically establish a scientific research and innovation system mechanism that adapts to the innovation-driven development strategy and meets the requirements of scientific research and innovation paradigm change, the ability of independent innovation has been significantly improved, high-level innovative talents have emerged, the role of scientific research and innovation in leading talent training has been significantly enhanced, the level of service to society has been significantly improved, and the "four centers" have been built for Beijing's high-level talent highland and construction. Provide strong support.
