Known as "Snow Ruyi", China's National Ski Jumping Center, located in Zhangjiakou, is one of the most iconic venues of the Beijing Winter Olympics. Under this beautiful and magnificent "Snow Ruyi", there is also a high-tech "snow screen" that will broadcast promotional videos from all over the world, including Anhui, to the audience before and after the competition. This is a panchromatic laser projector jointly developed by the enterprise of Hefei High-tech Zone and the University of Science and Technology of China, which projects thousands of square meters of projection screen on the snow under the "Snow Ruyi".
Represents the latest achievements of China's advanced display technology
Hefei Full Color Display Technology Co., Ltd., located in Hefei High-tech Zone, is one of the few laser full-color display technology enterprises in the world, which is committed to the development of ultra-high-definition full-color display and the research and development and application of a new generation of display technology. The enterprise is led by two academicians led by a scientific research team, led by a professor of the University of Science and Technology of China, adheres to the independent research and development of core technologies, undertakes the research of many major projects such as the national key research and development plan, and makes a number of new breakthroughs in the field of laser display. As one of the key special projects of the "Science and Technology Winter Olympics" "Smart Presentation of Snow Venues and Advanced Display Technology Research and Application Demonstration", the "Large-scale Complex Surface Panchromatic Laser Projection Display Technology Research", officially entered the Zhangjiakou National Ski Jumping Center, and will display the latest achievements of China's advanced display technology during the Winter Olympics.
According to Xu Lixin, chairman of The Full-Color Light Display, the project uses two 100,000 lumens ultra-high brightness high-definition laser projectors to project onto the snow surface in the middle of the football field at the end of the jump platform, "The projection display area is more than 1,000 square meters." "It is understood that compared with the general projection, the kennel laser projection has a wider color gamut, higher brightness, and the advantages of healthy eye protection and low energy consumption, so it has been adopted by the Winter Olympics to show the latest achievements of China's display technology." In view of the characteristics of fluffy snow, we have jointly carried out scientific and technological research with experts from the University of Science and Technology of China to achieve a large-scale and complex surface panchromatic display. ”
According to reports, during non-competition time, this super large "snow screen" located under "Snow Ruyi" will play wonderful images from all over the world, including Anhui, so that the audience can understand the customs and development achievements of various places after the competition, and appreciate the charm of the "Science and Technology Winter Olympics". At present, the equipment has entered the field, and the daily boot test is more than 3 hours, "from the test situation, the stability is high, and it has been trouble-free operation." Moreover, the picture quality is clear, the color is realistic, and it is not disturbed by the projection surface material, so as to achieve large-scale display. Xu Lixin said.
It is understood that when the Winter Olympics are over, "Snow Ruyi" will become a new landmark in Zhangjiakou City, and the large-screen outdoor viewing of the full-color laser display will also be retained.
The "Winter Olympic Version" translation equipment facilitates barrier-free communication
At the Winter Olympics, players from all over the world will gather in Beijing and other competition areas, and due to the requirements of epidemic prevention and control, volunteers can not use mobile phones when communicating with them. As the "exclusive supplier of automatic voice translation and translation for the Winter Olympics", iFLYTEK will provide a variety of portable and wearable translation devices to enable volunteers to communicate with foreign athletes without barriers.
It is understood that as the R&D undertaking unit of the "Winter Olympics" key special project "Key Supporting Technologies and Equipment for Multilingual Language Services for the Winter Olympics", iFLYTEK has developed core technologies such as multilingual speech processing for the Winter Olympic scenario, multilingual machine translation with the characteristics of the Winter Olympics and multilingual information acquisition and interaction based on intelligent questions and answers, built a voice and language service platform for the Winter Olympics, and developed portable translation equipment, wearable translation equipment, intelligent question answering equipment, etc. for the Winter Olympics. The event multimedia conference office and information release system, according to the unified requirements of the Winter Olympic Organizing Committee to the Winter Olympic Unified public service APP "Winter Olympic Pass" to provide voice translation services.
"For example, portable translation equipment, specifically for the Winter Olympics to add millions of professional vocabulary and industry terminology, covering a variety of sports and referee language, can meet the cross-language communication needs of athletes, coaches, spectators and so on." The wearable translation device is equipped with the function of call noise reduction for the noisy ambient sound of the Winter Olympic venues, which realizes synchronous translation and transcription while talking and mobile phone app, which can meet the multimedia interviews of the Winter Olympics and cross-language communication between the staff and coaches of the Winter Olympics. Zhang Wei, project manager of iFLYTEK Winter Olympics, introduced that these equipment and systems have been tested and demonstrated in test competitions such as the International Bobsleigh Federation World Cup, Snowboarding and Freestyle Ski Obstacle Chasing World Cup.
"Hefei Air Purification Technology" makes the Winter Olympic venues cleaner
In addition to the full-color light display, Hefei also has many high-tech enterprises that will help the Winter Olympics. Among them, thousands of air purification components produced by Beacon Electric Co., Ltd., located in Hefei Shushan Economic and Technological Development Zone, have been operating at the National Gymnasium and Speed Skating Hall in the Beijing Winter Olympic Venues, which will "escort" the air quality in the venues during the Winter Olympics.
It is understood that in 2019, the National Stadium and speed skating hall in the Venues of the Beijing Winter Olympics carried out supporting renovation and construction, and many air purification brands at home and abroad all participated in the competition of the project. "The Beijing Winter Olympics Organizing Committee set strict standards for the venue's air conditioning system, and in the end, Beacon Electric stood out." Guo Xiaoyuan, deputy general manager of Beacon Electric, said.
According to reports, in order to meet the strict requirements of the air quality of the Winter Olympic venues, the company adopts advanced technology and technology, which can efficiently purify the dust haze in the inhalable particulate matter and fresh air supply in the venue building, and has a strong treatment effect on volatile organic compounds and bacterial viruses. In recent years, Beacon's air purification products have been successively applied to the main venue of the "Belt and Road Summit", the APEC Head of State Villa in Beijing, and the headquarters of state-owned enterprises such as the Asian Infrastructure Investment Bank and Sinopec China Mobile.
