The closing ceremony of the Winter Olympic Games, the national stadium by countless "stars" convergence of the "dream of the five rings", let the audience stunned. Little known is that the lighting of the "dream five rings" used to make the country quite proud of the aerospace team and "high precision" equipment.
Long March Tianmin, a wholly owned company of Beijing Institute of Space Launch Technology, is responsible for the ground stage system of the opening and closing ceremonies of the Winter Olympic Games. "The 'Dream Five Rings' at the closing ceremony of the Winter Olympic Games and the one at the opening ceremony of the 2008 Olympic Games were both produced in the same factory. The five rings slowly rise technical approach, also similar to the 2008, like magic." Long March Tianmin Chief Engineer Shen Jigang said, slowly rising "Dream Five Rings" on the stars, in fact, by tens of thousands of LED light beads put together, these lights are welded on a huge wire mesh, steel wire are wrapped in a layer of black plastic skin, so as not to reflect the "help ". When the lights gradually darkened, slowly rising "dream five rings" as if suspended in the air.
This "dream five rings" in the slow rise before, where to hide? Shen Jigang said with a smile: "We must remember the opening ceremony of the Winter Olympics, the ice cube and ice five rings, right? We also did. At that time, the ice rings were hidden inside the ice cube, to the closing ceremony, we took out the ice rings, freeing up space to place the dream five rings." As the Winter Olympic Games opening and closing ceremony stage system from creativity, design to assembly, commissioning, application of the first-hand experience, Long March Tianmin services to protect the opening and closing ceremonies of the team members have said that the reuse of stage devices, is the embodiment of the concept of the Green Olympics.
Compared with the 2008 Olympic Games opening ceremony, the closing ceremony of the Winter Olympics "Dream Five Rings" using LED light beads to be more energy efficient, and the brightness can be adjusted. Shen Jigang still remembers, the Winter Olympic Games opening and closing ceremony general director Zhang Yimou often said to everyone: "We are responsible for the wonderful, aerospace is responsible for success." It was this statement that gave great encouragement to the team members of the Long March Sky People's Service Guarantee for the opening and closing ceremonies, making each idea a reality. "The director team is extremely demanding, just the brightness of the LED beads this item, it was modified several times, although each change is not large, but we are pursuing this spirit of excellence, which is also the character of Chinese aerospace people." Shen Jigang said, the 2008 "Dream Five Rings" loaded battery can only last about 5 minutes, the closing ceremony of the Winter Olympics "Dream Five Rings", can continue to light up for more than 2 hours, "which also reflects the progress of science and technology On the one hand."
Control "dream five rings" slowly rise, is a wireless remote control device, compared to the equipment used in 2008, stronger anti-interference ability, higher security level. The reason why such a "high precision" device was used was that when selecting the supplier, Long March Tianmin gave full play to the advantages of the aerospace system engineering management model and selected the best among the best nationwide, successfully making the "Five Rings of Dreams" use aerospace equipment. Gao Jun, general manager of the stage business department of Long March Tianmin, said that this management model also realized "cost reduction and efficiency increase". In the whole process of the opening and closing ceremonies of the Winter Olympic Games from creativity to reality, Long March Tianmin team cooperated with Zhang Yimou's creative team and completed more than 20 rounds of continuous adjustment and optimization of creative solutions, saving nearly 10 million yuan.
