What are the mysteries of these winter Olympic black technologies?

The Beijing 2022 Winter Olympics is in full swing, and more and more people have found that scientific and technological elements have brought many valuable highlights in this international event.

△ Upper left, 13 intelligent sentries, are exerting 200 guard forces, guarding more than 15 square kilometers; in the upper right, Hisense Video helps the development of the first domestic snow wax car, and can also see the smooth competition screen at minus 30 degrees Celsius; in the lower left, Lenovo provides a self-developed single-lead three-lead electrocardiogram for the Chinese short-track speed skating national team and the Chinese speed skating national team, which can help athletes receive high-frequency sampling through the sensorless wearable device; lower right, Guangfeng Technology played the Olympic five rings above the Shenzhen branch venue at the opening ceremony of the 2022 Winter Olympic Games.

Smart "Sentinel"

The climatic and environmental conditions are harsh, and the temperature difference between day and night is as high as tens of degrees, so how to provide safety protection for the Winter Olympics has become a problem.

Zhangjiakou Secret Garden Genting Park, one of the venues for the Beijing 2022 Winter Olympic and Paralympic Winter Games, can reach minus 40 degrees Celsius at night. After deploying the intelligent sentry robot jointly developed by Zhongke Zhiyun and Yunding Technology, it can automatically and accurately determine the category of the intruder, and upload the monitored situation or the intruder's whereabouts to the background command center.

It is understood that this intelligent "sentinel" uses the leading identification algorithm and anti-intrusion technology owned by Zhongke Zhiyun. Behind it is the core self-learning framework algorithm owned by the X-Brain platform independently developed by Zhongke Zhiyun, which can distinguish low feature differences and solve the problems of anti-attack, anti-camouflage and stability.

Domestic snow wax car

Snowboard waxing requires a harsh working environment, and an advanced snow wax truck becomes particularly important. Previously, the core technology of snow wax vehicles was monopolized by developed countries in ice and snow sports for a long time. After Shandong Province received the task of developing the country's first snow wax car from the State General Administration of Sport, it set up a joint research headquarters and organized more than 1,000 people to race against the clock to carry out joint research.

Hisense Vision undertook the research and development of the display solution on the snow wax truck - it needed to be able to achieve excellent picture quality effects in minus 30 degrees Celsius, outdoor high brightness, and wind and snow.

In response to these challenges, Hisense Video chose the flagship display product that realized technological innovation this year - Hisense ULED TV U7G-PRO, through Hisense's self-developed chip and ULED backlight partition control technology, achieved XDR effect, reaching 1600 nits peak brightness and 10000000:1 dynamic contrast, which can ensure that athletes and coaches can see the real and smooth game screen even in the noon sun on the ice and snow field.

It is understood that since its delivery on October 27, 2021, the first domestic snow wax car manufactured in Shandong has traveled more than 10,000 kilometers from Beijing to Xinjiang, Shanghai and Beijing, withstanding various tests such as long-distance driving, plateau climate, low ice and snow, and strong wind and bad weather, and has become a veritable support platform for the national cross-country skiing team.

No sense of wearing

The Olympic rush is inseparable from the hard training of athletes and the blessing of innovative scientific and technological strength.

It is reported that Lenovo has provided an independently developed electrocardiometer for the Chinese short track speed skating national team and the Chinese speed skating national team, which can help athletes receive high-frequency sampling through the sensorless wearable device, and form a complete set of intelligent training solutions through the medical-grade sign data platform and cooperate with thinkplus conference tablets, which can achieve the purpose of intelligent management of athletes' competitive status. According to the data, this Lenovo three-lead medical grade wearable Holter ECG recording instrument LenovoH3 is a product independently developed by Lenovo and obtained a medical device registration certificate. To help coaches and athletes master training efficiently, Lenovo offers aerospace application-grade ThinkPad P-Series mobile graphics workstations with powerful processing power and professional-grade graphics cards to make training video ultra-high-definition image analysis stable and smooth.

"Painting the Five Rings on the Clouds"

On the evening of February 4, at the Shenzhen branch of the opening ceremony of the Winter Olympics, Guangfeng Technology used the independently developed ALPD laser display technology to write out the four characters of "one in the world" on the cloud, and typed the "five rings" logo in the cloud to add color to the Winter Olympics.

According to the on-site technical personnel, the equipment using this technology can greatly improve the electro-optical conversion efficiency, reduce heat loss, combined with the heat dissipation technology of 3DVC, the volume is doubled, and can better solve a number of technical problems such as low electro-optical conversion efficiency, large heat generation, and the need for large heat dissipation devices. At the same time, according to the needs of the project "cloud book", the ultra-long-distance projection technology is synchronously superimposed.

According to the data, as one of the first batch of listed enterprises on the Science and Technology Innovation Board, Guangfeng Technology invented ALPD laser display technology in 2007, taking the lead in realizing technology industrialization in the world.
