What are the black technologies for UPS in the 2008 Beijing Olympics?

The black technology of UPS for the 2008 Beijing Olympic Games is as follows:

The 2008 Beijing Olympic Games adopted a large number of the world's cutting-edge new technologies, such as ground lifting stages, multimedia, ground LED systems, and command systems. , communication systems and dozens of other high-tech technologies, covering many fields.

1. Digital light

The five Olympic rings slowly rise in the bird's nest and fly into the vast night sky; ancient Chinese calligraphy and painting scrolls slowly unfold, showing the classical artistic conception of ink painting; ancient On the Silk Road, huge wooden boats ride the wind and waves - these stunning visual effects are outlined by the gorgeous lights of the Bird's Nest. The 2008 Beijing Olympics used digital lights: PG lights, which are high-brightness projection lamps. They use optical projection principles and use high-brightness light sources to project the content on the film onto the ground in full color, which can form images at night. Very visually impactful picture effects. In the opening ceremony performance, the large scroll that runs throughout the performance in the center of the venue, and the progressive animations from ancient times to modern times are successively displayed on the scroll, were all projected to the center of the venue by this PG light after pre-production. The simplicity of the black and white contrast of Chinese ink paintings, the splendor of Western oil paintings, and the rich colors of Impressionism are all presented by this high-tech technology.

2.LED

In the 2008 Olympic Games, LED was utilized to the maximum extent. The opening scroll is opened on a huge LED screen. The screen is 147 meters long and 22 meters wide. It is a huge platform with the highest technological content and is covered with 44,000 LEDs. The light and shadow effects produced by LED are closely combined with the performance, transforming into various patterns, leading the audience into a dreamlike world. The LED has been tested repeatedly and has completely withstood tests such as being stepped on by actors and being immersed in water. Although the entire opening ceremony took a long time, technological breakthroughs such as batteries solved the energy problem of LEDs.

3. Aluminum alloy material

At the opening ceremony of the 2008 Olympic Games, a large hole was opened in the center of the stage, and an "Earth" six stories high and about 20 meters in diameter slowly opened rise from it. Where is such a big "earth" hiding? It turns out that this "earth" is first compressed underground, which means that the spherical structure must be flexible. It is oval when placed on the ground, and becomes spherical after being pulled up by the steel wire above. After the lifting platform raises the sphere, the actors need to perform on the facade of the sphere, so it needs to have strong stability after it is raised to ensure the safety and effectiveness of the performance. This all relies on high-tech aluminum alloy photosensitive materials to make the "earth" flexible and stretchable.

4. Multimedia

At the opening ceremony of the 2008 Olympic Games, "birds" and "whales" were flying and swimming freely above the huge scrolls. How were these made? ? It turns out that slide projection technology was used at the opening ceremony in the past, but this time multimedia equipment was used. It can use computers to digitize media information such as text, graphics, images, animations, sounds and videos, and then integrate them into a certain interactive interface to create a bowl-shaped screen of thousands of square meters on the top of the "Bird's Nest" , showing a clear picture of a "whale" swimming freely, expressing the harmonious coexistence between man and nature.

5. Digital Ignition

The 29 huge colorful footprints composed of fireworks kicked off the 29th Beijing Olympic Games, symbolizing that the modern Olympic event is moving towards Beijing step by step. Enter the bird's nest. The ignition of these 29 large footprints is controlled by a computer system and uses digital ignition. This technology can ignite all fireworks in a very short time, ensuring that the fireworks can cross 3.5 kilometers in just a few seconds. In addition, there are 22 launch points in the dragon-shaped water system next to the Bird's Nest. After digital control using a computer, all the fireworks bombs can be shot into the sky one after another, making the fireworks look like a giant dragon in the air. Although traditional fireworks are still used, after digital ignition, the fireworks present a different visual effect than before.
