How does the main torch of the Winter Olympics continue to burn? The answer is in this "snowflake."

Through many simulation calculations and field tests, the "Ice Five Rings" that appeared at the opening ceremony were able to maintain structural stability in The 6 winds, and retained the light and ethereal feeling as much as possible.

According to CCTV news, at the opening ceremony of the Beijing Winter Olympics, the ceremonial links such as the raising of the five Olympic rings and the lighting of the torch were ethereal and romantic, and the core device behind these two links also aroused the curiosity of many viewers. How did they achieve the stunning visuals at the opening ceremony? Let's take a look at the secret report sent back by the reporter.

Reporter: The device that is slowly rising, the staff called it Ice Cube, and he undertook a very important ceremonial display at the opening ceremony, because our Olympic rings are hidden in this piece of ice. In fact, at the beginning, when our design was to carve the five rings, this device would throw out the ice cubes of the real thing, but in the end, why was it comprehensively displayed with floors and lighting effects? Let's listen to the technician decryption.

Wang Jian, technical leader of the Winter Olympics Special Office of China Aerospace Science and Technology Group: The earliest is to throw out simulated ice cubes, we designed 6 hatches around the perimeter, the front 4, and the two simulated ice cubes made of plastic on the side were thrown out. But the gap where the ice is thrown is ugly, too fake, a bit of a broken phase.

At the opening ceremony, the slowly rising link of the five rings pushed the atmosphere of the scene to a climax, but in the initial design, the director team proposed to project an external light source onto the five rings to make it appear to be a glittering effect. But after many attempts, the effect is not ideal. In the end, the technical team proposed an improved solution of "five rings self-emitting".

Wang Jian, technical leader of the Winter Olympics Special Office of China Aerospace Science and Technology Group: In the design of the light panel, one is the LED full-color light board and flexible light board that we are now taking, and the second is the light board cover, which is actually a good filter, so that the two colors match up, and finally through the color filter to form this ice feeling.

The problem of beauty is solved, in the case of wind, how to maintain the stability of the five rings of Weia lifting? It's a new problem. Through many simulation calculations and field tests, the "Ice Five Rings" that appeared at the opening ceremony were able to maintain structural stability in The 6 winds, and retained the light and ethereal feeling as much as possible.

Reporter: The device that is descending is another core device at the opening ceremony, and the staff called him the Snowflake Stage, so he appeared twice at the opening ceremony, once as a landscape display and the second as an important torch installation. So a small torch, his own endurance is limited, how can it achieve sustained and stable combustion? In fact, the answer is also in this snowflake.

The original design scheme was to hide the cylinder directly in 5 "petals". However, considering the difficulty of replacing the cylinder, the reliability is limited. The technical team hit the idea in the sky again.

Wang Jian, technical leader of the Winter Olympics Special Office of China Aerospace Science and Technology Group: There is a control device or Weiya called this control device or Weiya on it, and there are more than a dozen motors composed of steel cable lifting system, as well as the release system of the gas path, the release system of the cable, and the roll-up system, so the gas road is on it.

Snowflake table device, torch device, ice cube device, lifting device, the wonderful ceremonial function display at the opening ceremony, requiring them to coordinate accurately. But in fact, this kind of "precision collaboration" on the basis of the intelligent scheduling system also needs to be manually "fine-tuned".

He Guanjie, technical leader of the ground stage system at the opening ceremony of the Beijing Winter Olympics: Our ground stage system, unlike other stages, needs to be coupled with the lighting and sound, as well as a large number of LED display screens, so it is necessary to follow the director's password and follow the rhythm of the entire performance to make some ten-second or second-level adjustments. Therefore, for this reason, when we operate, we still retain a part of the operation function of human hands.

In the one-and-a-half-hour opening ceremony event, nearly a hundred command passwords were required to complete. But this is not difficult for astronauts who are accustomed to the use patterns and working characteristics of space launch sites. After nearly three months of running-in with the director team, the technicians have been able to complete the entire operation process of the opening ceremony with precision and proficiency.

He Guanjie, technical leader of the ground stage system at the opening ceremony of the Beijing Winter Olympic Games: We are the conductors of the ground stage system. He was responsible for the password interaction with the director. When to do a mechanized action, then his password will be accurately issued to our operator hand, and then the operation. In fact, the automation program of the division action has been installed in the computer in its entirety, and when you receive the director's password, you only need to press two keys, and the system will run immediately, so it can meet the requirements of accurate performance.

The Yellow River rushes, the ice cube towers, the Olympic rings rise slowly, the audience shouts tsunami-like cheers straight into the clouds, the opening ceremony of the Beijing Winter Olympic Games with the imagination of the art, the wisdom of exploring the vast universe, more than 10 months of technical support implementation, to the people of the world to show the people of the world Chinese hospitality.
