At the closing ceremony of the Winter Olympic Games, the "Starlight Five Rings" gathered by countless "stars" in the National Stadium surprised the audience. What is less known is that the "Five Rings of Starlight" are lit with a space team and "high-tech" equipment that the Chinese people are proud of.
Long March Tianmin, a wholly-owned company of the Beijing Institute of Aerospace Launch Technology, is responsible for the ground stage system for the opening and closing ceremonies of the Winter Olympics. "The 'Starlight Rings' at the closing ceremony of the Winter Olympics, and the one at the opening ceremony of the 2008 Olympic Games, are all produced by a factory. The technique of the slow rise of the five rings is also similar to that of 2008, just like magic. Shen Jigang, chief engineer of the Long March Tianmin, said that the stars on the slowly rising "Starlight Five Rings" are actually made up of tens of thousands of LED lamp beads, which are welded on a huge steel wire mesh, and the steel wires are wrapped in a layer of black plastic skin, so as not to "wear gangs" because of reflections. When the lights gradually dimmed, the slowly rising "Five Rings of Starlight" seemed to be suspended in the air.
Where is this "Five Rings of Starlight" hidden before it slowly rises? Shen Jigang smiled and said, "Everyone must remember the ice cube and the ice ring at the opening ceremony of the Winter Olympics, right?" That's what we do. At that time, the ice ring was hidden inside the ice cube, and at the closing ceremony, we took out the ice ring and made room to place the starlight ring. As witnesses of the stage system for the opening and closing ceremonies of the Winter Olympic Games from creativity, design to assembly, commissioning and application, the team members of the Long March Tianmin Service Guarantee Opening and Closing Ceremony all said that the reuse of stage installations reflects the concept of the Green Olympics.
Compared with the opening ceremony of the 2008 Olympic Games, the LED lamp beads used in the "Starlight Five Rings" at the closing ceremony of the Winter Olympic Games are more energy-efficient, and the brightness is adjustable. Shen Jigang still remembers that Zhang Yimou, the general director of the opening and closing ceremonies of the Winter Olympics, often said to everyone: "We are responsible for the wonderful, and aerospace is responsible for success." "It is this sentence that gives great encouragement to the team members of the opening and closing ceremonies of the Long March Tianmin Service Guarantee, so that each idea becomes a reality." The director team is extremely demanding, just the brightness of the LED lamp beads, it has been modified several times, although each change is not large, but what we pursue is this spirit of excellence, which is also the character of Chinese astronauts. Shen Jigang said that the battery loaded with the "Starlight Five Rings" in 2008 can only last about 5 minutes, and the "Starlight Five Rings" at the closing ceremony of the Winter Olympics can continue to be lit for more than 2 hours, "Which is also an aspect of scientific and technological progress." ”
Controlling the slow rise of the "Starlight Five Rings" is a wireless remote control device, which has stronger anti-interference ability and higher security level than the equipment used in 2008. The reason why such "high-tech" equipment can be used is because when selecting suppliers, Long March Tianmin Company gave full play to the advantages of the aerospace system engineering management model, selected the best among the best in the country, and successfully made the "Starlight Five Rings" use aerospace equipment. Gao Jun, general manager of the stage business department of Long March Tianmin Company, said that this management model has also achieved "cost reduction and efficiency increase", in the whole process of the opening and closing ceremonies of the Winter Olympic Games from creativity to reality, the team of Long March Tianmin Company cooperated with Zhang Yimou's main creative team to complete more than 20 rounds of continuous adjustment and optimization of creative programs, saving nearly 10 million yuan in costs.
