At 20:04 on February 4, the opening ceremony of the XXIV Winter Olympic Games was held at the Beijing National Stadium (Bird's Nest). By integrating the concepts of scientific and technological innovation, low-carbon environmental protection and sports health, the opening ceremony focused on China's modernity and future, dedicated romantic, aesthetic and warm grand events to the world, and showed the beauty of nature, humanities and sports.
The main torch ground core device system created by Dafeng
It realizes the perfect combination of innovative technology and exquisite art
After crossing the three divisions of Beijing, Yanqing and Zhangjiakou, and passed by more than 1,200 torchbearers, the torch of the Beijing Winter Olympics came to the Bird's Nest. After Zhao Weichang, Li Yan, Dayang Yang, Su Bingtian, and Zhou Yang passed in turn, the torch was handed over to Diniger-Yilamujiang and Zhao Jiawen. The two men walked up to the torch stand and placed the torch in their hands in the middle of the big snowflake, and the main torch tower was lit.
The 260-ton steel structure lifts and lowers quickly, relying on the meticulous control of the control system, to lift the main torch from 10 meters underground to the center of the stage in 69 seconds. The torchbearer inserted the torch into the center of the "Snowflake", and the main torch ground core device system created by Dafeng lifted the "snowflake" into the air with a light weight, and the Olympic flame was intertwined with 96 crystal clear snowflakes and 6 flowing olive branches, which drew a successful conclusion for the opening ceremony.
How to carry out the secondary creation and implementation of the main torch
It is a challenging and exciting undertaking
The use of the main torch of the Beijing Winter Olympics and the magical idea are groundbreaking. Dafeng creative team has never been afraid of challenges, and Feng Jialong, chief creative officer of the star team who has just created the stage of the CCTV Spring Festival Gala in the Year of the Tiger, Feng Qiyun, chief designer, and Yan Huafeng, chief engineer, have once again joined forces to bravely take on heavy responsibilities. Dafeng's creative team creates around the ideas of science and technology, ingenuity and aesthetics, boldly conceiving, bravely innovating, repeatedly demonstrating, and carefully experimenting, and finally turning the whimsical ideas into magical and beautiful reality.
The main torch ground device system consists of three parts: led chassis, main torch auxiliary flip lift device and step step lift device.
The main torch adheres to the concept of green and sustainable development for R&D and design. In addition to the main flare fuel using hydrogen as fuel, it is guaranteed to be used in extremely cold weather and can withstand wind level 10. The main flare floor unit is also designed and manufactured using environmentally friendly materials and processes. The main torch flipping lifting device drive system is composed of 4 sets of large and precise rack mechanisms, up to 9 meters long rack under the precise control of Dafeng's unique control system, lifting and lowering different heights and rotating different angles, completing complex curve movements, lifting the main torch 8 meters high.
The step step lifting device is designed with a clever flip compensation device, so that the 24 steps symbolizing the Chinese 24 solar terms culture are always automatically maintained horizontally and consistently, even if the steps are in motion, the torchbearer can pick up the steps.
The creative and varied main torch installation not only has a whimsical imagination, but also has the artistic appeal of shaking the heart. What Dafeng has done is not only to use hard-core technology to expand the three-dimensional exhibition space of the core link of the opening ceremony, but also to perfectly integrate green technology with the Beijing Winter Olympics, so that the world can see China's strong scientific and technological innovation and artistic creativity.
Ingenuity to do every detail
Made in China to cast glory
The Ground Core Installation System for the Opening Ceremony of the Winter Olympics is a race against time and circumstance. The ground of the Bird's Nest site is all LED large screens, can not withstand large goods, the ground core device system to be installed in the bird's nest central area lifting table steel frame, for this installation is a major challenge.
Dafeng innovatively adopts a 260-ton crane with a lifting span diameter of more than 60 meters, and the construction plan of lifting a single piece of ground core device equipment into the central lifting platform at the bird's nest passage for splicing and installation has been approved by the Olympic Organizing Committee, the supervision team and experts.
The main torch system is the core device with the highest level of confidentiality at the opening ceremony, and the installation and commissioning of the project need to be arranged from 24:00 midnight to 8:00 am the next day, which is the coldest time of the year in Beijing, and the temperature on site is basically hovering at minus 10 degrees Celsius. The Dafeng strivers who have the courage to take responsibility and are not afraid of difficulties are full of enthusiasm for the glory of the country, practicing the core values of "sincerely being a person and doing things in a down-to-earth manner", letting his bone-chilling wind whistle in his ears, still meticulously focusing on the construction of the main torch, achieving the dreams in his heart, and casting the glory of the country.
Deep participation in the "Winter Olympics of Science and Technology"
Dafeng "black technology" shines on the field
As one of the key participating units in the construction project of this Winter Olympic Games, Dafeng not only provided the core device system for the core link of the opening ceremony of the Winter Olympics, but also deeply participated in a number of topics of the "Science and Technology Winter Olympics" National Key R&D Program project, and undertook the research and development of the "Sports Display Interactive Presentation Terminal".
Affected by the epidemic, the audience's entry into the game has undoubtedly been affected. To make up for this regret, Dafeng installed "glow sticks" on the 8,000 seats at the National Stadium and the Wukesong Sports Center. This is not an ordinary glow stick, it will be based on wireless group control technology and active positioning technology, according to the content created by the staff in the cloud, presenting different atmospheric effects such as urban animation, cheerful pandas, fireworks, snowflakes, flags of the participating countries, etc., known as "black technology".
When there is an audience, the audience can hold the glow stick in their hands and wave it, which can form a good interaction between the audience and the game and increase the atmosphere of the venue. When there is no audience, this glow stick is placed on the armrest, which can produce a variety of soft lights, and each individual glow stick has 256 colors, showing the effect of the audience full.
Dafeng provides seating systems for 75% of winter Olympic venues
Green, environmental protection, multi-functional has become a model
Dafeng completed the seating system for 75% of the spectator-seated venues of the 2022 Beijing Winter Olympics, of which all the competition venues in Beijing were provided by Dafeng. In the visible details, Dafeng's seating system highlights six highlights: first, the appearance design lines are smooth; second, all the edges and corners are rounded corner transitions, which will not cause harm to the audience; third, the bending strength and impact strength are very high; fourth, the seat is ergonomic, avoiding the fatigue caused by watching the game for a long time; fifth, the seat raw materials have reached the international leading level in terms of weather resistance and flame retardancy; sixth, the seat has a long service life, and the discarded seat can also be recycled. After crushing, the raw materials can be recycled and reused, and there is no pollution to the environment. In the invisible details, Dafeng has begun to focus on the use of eco-friendly processes to eliminate carbon emissions in the production process.
The Dafeng seating system is not only green and environmentally friendly, but also maximizes the efficiency of venue use through intelligent movement changes to achieve the transformation of venue functions. Among the five venues on the ice, only the National Speed Skating Hall is a new venue, and the rest are the existing venues of the 2008 Beijing Olympic Games, which have the ability to convert the venues in winter and summer, so that the Olympic "heritage" can be used to the greatest extent.
While deeply participating in the Beijing Winter Olympics, Dafeng also comprehensively assisted the Hangzhou Asian Games in many links, not only creating a "smart dance screen" to create a wonderful "Hangzhou 8 minutes" at the Jakarta Asian Games, but also providing overall solutions and seating systems for multiple venues such as the Hangzhou Olympic Sports Center and the Asian Games E-sports Hall; Dafeng will also actively participate in the creation of core links and contribute to the "Intelligent Asian Games".
