On February 3, the Chinese women's ice hockey team played the Czech Republic in the first match at the Wukesong Sports Center. Before the game, thousands of glow sticks placed in the audience were combined into a "screen", showing two beating panda patterns through bright extinction and color changes, cheering up the upcoming teams of both sides. According to the technical staff, these glow sticks can accept the unified control of wireless signals, setting off the warm atmosphere of the arena.
In order to create the atmosphere of the Winter Olympic Games, Gan Lihong, an engineer of Zhejiang Dafeng Sports Equipment Co., Ltd., participated in the research and development of projects such as "Interactive Experience Audiovisual Control System for Wearable Light-emitting Devices" and "Cloud-connected Audience Interactive Experience System Integration and Application Demonstration".
Gan Lihong introduced that the common glow sticks in life are mostly single-person operations, even if the centralized control of the radio can be realized, most of them can only play the content stored in the glow sticks regularly, and it is difficult to carry out real-time large-scale linkage. The glow sticks arranged in the audience of the Wukesong Sports Center realize the "wireless group control technology", the glow sticks are shaped like a sand hammer, and the rounded head is the luminous part, which can display 256 colors, and listen to the "password" of the on-site server through wireless communication, showing the pattern or effect that has been created in advance and stored in the cloud.
During the "Meet in Beijing" test match held last year, thousands of glow sticks achieved countdowns, panda strikes, and stars. But with so many glow sticks, how does the background know their exact location for precise control? Gan Lihong explained that when the glow stick is placed in the seat, the seat position information can be read and "bound" by radio frequency technology, and the positioning data can also be obtained through active positioning technology. After determining the location, only a computer is needed on site to effectively control 100,000 glow sticks.
At this Winter Olympic Games, more than 7,000 glow sticks will be combined with the lighting and sound effects of Wukesong Sports Center to show the theme of the Winter Olympic mascot, the theme of festivals, and the theme of Beijing Street View.
