The opening ceremony of the Beijing Winter Olympics uses the industrial Internet platform "Long March Cloud"

At the opening ceremony of the Beijing 2022 Winter Olympics held on February 4, the huge LED ground display system attracted a lot of attention. According to the news center of the State-owned Assets Supervision and Administration Commission of the State Council, 15 and 12 of the First Academy of Aerospace Science and Technology Group are responsible for the construction of the stage and the ground screen. The construction area of ​​the entire stage system is about 21,000 square meters, and the ground display screen is composed of more than 40,000 screens, covering an area of ​​more than 10,100 square meters.

According to reports, behind the display screen, tens of thousands of signals are rapidly transmitted in complex lines. Relying on the Long March Cloud Platform, the industrial Internet platform of the 12 own academies of Aerospace Science and Technology Group, tens of thousands of screens are strung together. Humidity, voltage, and other working conditions are constantly monitored.

BOE previously stated that the system is currently the largest 8K ultra-high-definition terrestrial display system provided by BOE. As the world's largest ultra-high-definition ground display system, the overall area of ​​the system reaches 10,393 square meters.

In addition, BOE adopts multiple 8K+ resolution image fusion technologies, and the ultra-large-scale optical correction algorithm can perform pixel-level optical correction on each display screen, which can present a 100,000:1 ultra-high contrast ratio and 3840Hz ultra-high refresh rate. rate, and 29900 × 15096 ultra-high-resolution ultra-high-definition picture.
