The two torch runners will stay in the shape of snowflakes at the opening ceremony of the 2022 Olympic Games in Beijing. The main torch tower was lit and slowly lifted off, replacing the raging fire with a "small fire", realizing an ignition innovation in the history of the Olympic Games and passing on the concept of low-carbon and environmental protection.
"The ground device system of the main torch is like a 'lifter' for the main torch to be transmitted to the high altitude. It is composed of LED chassis, auxiliary overturning and lifting device of the main torch and step lifting device. This set of self-developed precision control system completes a series of lifting and flying actions." Zhejiang Dafeng Industrial Co.Ltd(603081) is the design unit of the ground device of the main torch. Fenghua, the person in charge of the company, can't hide his pride.
It is reported that the 260 ton steel structure rises and falls rapidly. Relying on the fine control of the aerospace software system, the main torch is lifted from the position of 10 meters underground to the center of the stage in 69 seconds. The torchbearer inserted the torch into the "snowflake" center. The ground core device system of the main torch created by Dafeng lifted the "snowflake" into the air as light as a weight. The Olympic flame complemented 96 crystal snowflakes and 6 elegant olive branches, marking a successful conclusion for the opening ceremony.
"This time, the director group gave very high requirements and imagination, which also brought great difficulties to our work. Fortunately, they were overcome and presented to the world perfectly." Yan Huafeng, chief engineer of the auxiliary overturning and lifting device of the main torch, introduced that the use mode and magical idea of the main torch of the Winter Olympic Games are groundbreaking.
"The ground core device system of the opening ceremony of the Winter Olympic Games is a race against time and environment. The ground of the bird's nest is a large LED screen, which can not bear large goods. The ground core device system should be installed in the steel frame of the lifting platform in the central area of the bird's nest, which is a major challenge for installation." Yan Huafeng said.
Zhejiang Dafeng Industrial Co.Ltd(603081) the construction scheme of innovatively using a 260 ton crane with a hoisting span of more than 60 meters in diameter and lifting a single piece of ground core equipment into the central lifting platform for splicing and installation at the bird's nest channel has been approved by the Olympic Organizing Committee, the supervision group and experts.
As one of the key participating units in the construction project of this winter Olympic Games, Zhejiang Dafeng Industrial Co.Ltd(603081) not only provides the core device system for the core link of the Winter Olympic opening ceremony, but also deeply participates in many topics of the national key R & D plan project of "science and technology Winter Olympic Games", and undertakes the R & D of "sports display interactive presentation terminal".
Affected by the epidemic, the audience entering the venue to watch the game has undoubtedly been affected. To make up for this regret, Zhejiang Dafeng Industrial Co.Ltd(603081) installed "fluorescent sticks" on 8000 seats in the National Stadium and Wukesong Sports Center respectively. This is not an ordinary fluorescent stick. Based on wireless group control technology and active positioning technology, it will present different atmosphere effects such as urban animation, happy pandas, fireworks, snowflakes, participating national flags and flags according to the content created by the staff in the cloud.
In addition, Zhejiang Dafeng Industrial Co.Ltd(603081) has also completed the seating system of 75% of the venues with auditorium for the 2022 Beijing Winter Olympic Games, of which all the seating systems of the competition venues in the Beijing competition area are provided by it.
It is worth mentioning that the 720 ° dome space of CCTV Spring Festival Gala in the year of the tiger was also completed by the Zhejiang Dafeng Industrial Co.Ltd(603081) team. It is reported that the creative design of this immersive space must be completed with high quality, high standard and high level within 50 days, and the on-site construction period is only 30 days. The Zhejiang Dafeng Industrial Co.Ltd(603081) team built the scene with three-dimensional technology, simulated the artistic scene, analyzed the structure, mechanics, dynamics, materials and other disciplines, directly applied the creative achievements to intelligent manufacturing in the form of data model, and gave the optimal on-site implementation scheme in the form of digital calculus. Finally, it achieved a breakthrough in the limitation of space and presented an "immersive space" for the global audience.
In recent years, Zhejiang Dafeng Industrial Co.Ltd(603081) has provided technical support for national events for many times with solid creative ability, technical ability and delivery ability, such as G20 summit, BRICs summit, world Internet Conference, etc. In the future, Zhejiang Dafeng Industrial Co.Ltd(603081) will create a new interactive experience with higher technology and deeper immersion.
