Images of Chinese watches flow on huge scrolls that are slowly unfolding, "birds" and "whales" soar freely over the "Bird's Nest", and humans stroll on the azure planet rising in Ran Ran, and the twinkling starry sky turns into a crystal-clear "Bird's Nest" ...
The visual and sensory shock makes the audience truly feel the "same dream". What magic did the opening ceremony of the Beijing Olympic Games do?
Yu Jianping, head of the technical production team of the opening ceremony, said: The shock comes from the massive combination of innovative solutions and high technology. Beijing has adopted the most complicated technical system in previous Olympic Games and a large number of world-class new technologies, which have distinctive characteristics.
The extraordinary light and shadow effects laid the foundation for the success of this opening ceremony. The LED (Light Emitting Diode), which is widely used in performances, has been used to the maximum extent here, creating the highest in history.
The opening scroll opens on a huge LED screen. The screen is 147 meters long and 22 meters wide. It is a huge platform with the highest scientific and technological content, which constitutes the largest stage of previous opening ceremonies, with 44, LEDs laid on it.
the "dream five rings" rising into the air are also drawn by 45, LEDs on a big network. Even the costumes of the actors are covered with LEDs. With the change of the formation of the actors, the starry sky descends on the earth and the phantom of the "Bird's Nest" reappears ...
On the ground system, Athens' idea is to transplant the Aegean Sea with a large pool, while Beijing uses the underground stage to float out the "painting axis" and slowly unfold the 5,-year history of China.
The central stage of the performance is a 2-meter-diameter lifting platform, which is hidden in a huge "pit" in the center of the stadium, and the cover at the top of the "pit" can be translated.
The scroll and the "Earth" both rise from this "pit", in which the scroll is placed in the cover plate in advance, and how can the "Earth" with a diameter of 18 meters hide? It turns out that this "earth" is compressed underground first, that is to say, the spherical structure must be flexible. After the ball is raised by the lifting platform, 6 actors need to perform on the facade of the ball, so it must have strong stability after being raised to ensure the safety and effect of the performance.
it is indispensable to mention the fireworks display.
The fireworks implementation adopts the patented technology of "chamber pressure emission". This technology can fire dozens of projectiles at the same time by controlling the pressure in the bore and the launching height, and can also be adjusted to form different shapes. Its plane shapes such as "big footprints" and "smiling faces" are very successful and are the main force of this fireworks launch.
The opening ceremony always used dozens of high and new technologies, involving many fields, and aerospace materials were also used in the opening ceremony, among which the paper used in the painting axis was the newly developed "honeycomb material".
The ground lifting stage, multimedia, ground LED system, command system, communication system and many other devices all adopt high technology. Except the communication system is imported technology, all other core technologies are innovative technologies with independent intellectual property rights.
Pay attention to the key sentence:
"The opening scroll opens on a huge LED screen. The screen is 147 meters long and 22 meters wide. It is a huge platform with the highest scientific and technological content, which constitutes the largest stage of previous opening ceremonies, with 44, LEDs on it. "
after reading this paragraph, I feel a little dizzy from a professional perspective! 147X22=3234㎡。 44, LEDs, with a density of less than 2 LEDs per square meter? The report is flawed. Continue to search for information:
Where did "birds" and "whales" come from? In the past, slide projection technology was used in the opening ceremony, but this time, all kinds of multimedia equipment were used. Thousands of square meters of "bowl-side" screens were built at the top of the "Bird's Nest", showing a clear picture of "whales" swimming freely, which well expressed the harmony between man and nature. This equipment is often used in the basketball court of NBA, but generally only about 8 sets are used. 12 sets were used in this opening ceremony. "
after reading this passage and referring to the pictures, it suddenly dawned on me that the scroll is a combination of LED and "Pani lamp". The so-called Pani lamp is a huge "slide projector" or "projector", which can use this facade of the building as a curtain! This scroll is not the LED screen, but the real screen, only the square in the middle. That's the area where the performers are active!
1. The overall image of the scroll is completed by the computer-controlled "Pani lamp" installed at the top of the gymnasium, and other parts do not emit light by themselves except the middle part of the scroll.
2. In the center of the reel, in an area with an area of about 16X9, RGB LED modules with a lattice spacing of 1cm are installed, with a square density of 1 modules. This density is also confirmed in the subsequent report "1 meters can distinguish LED particles".
3. This design is ingenious and cost-saving. Compared with the last Asian Games in Doha, this LED design has embodied the principle of saving.
