At 20:00 Beijing time on February 4, the opening ceremony of the 24th Winter Olympic Games was held at the Beijing National Stadium (Bird's Nest).This opening ceremony integrated technological innovation, low-carbon environmental protection, and sports and health concepts, showcasing China's modernity and future, presenting a romantic, beautiful, and warm event to the world, showcasing the beauty of nature, culture, and sports.
Spanning the Beijing, Yanqing, and Zhangjiakou competition zones, after more than 1,200 torchbearers passed the torch, the Beijing Winter Olympics torch arrived at the Bird's Nest. After the successive relay by Zhao Weichang, Li Yan, Da Yangyang, Su Bingtian, and Zhou Yang, the torch was handed over to Diniger-Yilamujiang and Zhao Jiawen.The two walked up to the torch stand and placed their torches in the center of the heavy snowflake, and the main torch tower was lit.
The 260-ton steel structure was rapidly lifted and lowered, relying on precise control by the aerospace software system, to raise the main torch from 10 meters underground to the center of the stage in 69 seconds. The torchbearer inserted the handheld torch into the center of the "snowflake,"The ground core device system for the main torch, created by Dafeng, effortlessly lifts the "snowflake" into the airThe Olympic flame, along with 96 sparkling snowflakes and 6 graceful olive branches, shone brilliantly, bringing the opening ceremony to a perfect close.
The use and creative ideas of the Beijing Winter Olympics main torch were groundbreaking. The Dafeng creative team has never been afraid of challenges. The star team that just created the stage for the Year of the Tiger CCTV Spring Festival Gala—Chief Creative Officer Feng Jialong, Chief Designer Feng Qiyun, and Chief Engineer Yan Huafeng—once again took on the challenge. The Dafeng creative team focused on technology, ingenuity, and aesthetic ideas, boldly imagining, innovating bravely, repeatedly verifying, and meticulously experimenting, ultimately transforming spontaneous ideas into magical and beautiful realities.
The main torch ground installation system consists of three parts:LED chassis, main torch auxiliary flipping and lifting device, and step step lifting device.
The main torch is developed and designed with the principles of green and sustainable development.In addition to using hydrogen as the main torch fuel, ensuring it can be used in extreme cold weather and can withstand wind level 10. The ground equipment for the main torch is also entirely designed and manufactured using environmentally friendly materials and processes. The main torch flipping and hoisting device drive system consists of four large and precise rack mechanisms. The 9-meter-long rack, under the precise control of Dafeng's unique control system, raises and lowers the rack at different heights and rotates at different angles, completing complex curve movements and lifting the main torch 8 meters high.
The step step lifting device features a clever flip compensation mechanism, allowing the 24 steps—symbolizing the 24 solar terms of China—to always remain level and maintain consistent elevation differences. Even when the steps are moving, the torchbearer can climb up the steps.
The main torch installation, full of creativity and diverse shapes, not only possesses imaginative imagination but also possesses a soul-stirring artistic impact. What Dafeng achieves is not just expanding the three-dimensional performance space at the core of the opening ceremony with cutting-edge technology, but alsoPerfectly integrating green technology with the Beijing Winter Olympics will showcase China's powerful technological innovation and artistic creativity to the world.
The ground core installation system for the Winter Olympics opening ceremony is a race against time and the environment.The ground at the Bird's Nest site is covered with LED large screens, which cannot support large loads. The core ground installation system must be installed on the steel frame of the lifting platform in the central area of the Bird's Nest, posing a major challenge for this installation.
Dafeng innovatively adopted a 260-ton crane with a lifting span diameter of over 60 meters, and at the Bird's Nest passageway, each piece of ground core equipment was hoisted into the central lifting platform for assembly. This construction plan was approved by the Olympic Organizing Committee, the supervision team, and experts.
The main torch system is the core device with the highest level of secrecy at the opening ceremony. The installation and commissioning of the project must be scheduled from midnight 24:00 to 8:00 the next morning.It was the coldest season and coldest period of the year in Beijing, with the temperature on site hovering around minus 10 degrees Celsius。 Dafeng strivers who bravely take responsibility and face hardships are filled with passion for bringing glory to the country, practicing Dafeng's core values of 'Be sincere in life, work diligently.' Even as biting winds howl in his ears, he remains meticulously focused on building the main torch, fulfilling his dreams and forging the nation's glory.
As one of the key participants in this Winter Olympics construction project, Dafeng not only provides core installation systems for the core segments of the opening ceremony,Da Fung has also been deeply involved in several projects under the National Key R&D Program for the 'Technology Winter Olympics' and undertook the development of the 'Sports Display Interactive Presentation Terminal.'
Due to the pandemic, spectators attending the games were undoubtedly affected. To make up for this regret, Dafeng installed "glow sticks" in 8,000 seats at the National Stadium and Wukesong Sports Center. These are not ordinary glow sticks; they use wireless group control technology and active positioning technology, and based on content created by staff in the cloud, they present different atmospheres such as city animations, cheerful pandas, fireworks, snowflakes, and national flags.Praised by authoritative media outlet Reference News as "black technology"。
When there are spectators, spectators can wave glow sticks in their hands, which helps create good interaction between the audience and the competition and enhances the atmosphere of the venue. When there are no spectators, these glow sticks are placed on the handrails to produce various soft glows,Each individual glow stick comes in 256 colors, creating a full audience atmosphere。
Dafeng completed the seating system for 75% of the venues with spectator seating for the 2022 Beijing Winter Olympics, among themAll venue seating systems in the Beijing division are provided by Dafeng。 In visible details, Dafeng's seating system highlights six major highlights: First, the exterior design features smooth lines; Second, all sharp corners are rounded transitions, so they do not harm the audience; Third, the bending and impact resistance are extremely high; Fourth, the seats are ergonomically designed to prevent fatigue caused by long viewing sessions; Fifth, the seats are made from internationally leading materials in terms of weather resistance and flame retardancy; Sixth, the seats have a long service life; discarded seats can be recycled, and the materials can be recycled after crushing, causing no environmental pollution. In the invisible details,Dafeng has begun focusing on using environmentally friendly processes to eliminate carbon emissions during production。
The Dafeng seating system is not only environmentally friendly but also enables venue function switching through intelligent movement changes, maximizing venue efficiency.Of the five ice venues, only the National Speed Skating Oval is newly built; the rest are renovated existing venues from the 2008 Beijing Olympics, enabling bidirectional switching between winter and summer events, maximizing the use of the Olympic "legacy."
While deeply involved in the Beijing Winter Olympics, Dafeng is also involved in multiple aspectsFully supporting the Hangzhou Asian Games, not only creating the "Smart Dance Screen" to create the spectacular "Hangzhou 8 Minutes" at the Jakarta Asian Games, but also providing comprehensive solutions and seating systems for venues such as the Hangzhou Olympic Sports Center and the Asian Games Esports Arena; Dafeng will also actively participate in the creation of core components, contributing to the "Smart Asian Games."
