According to the data on the official website of the Beijing Winter Olympic Organizing Committee, since January 23, the total number of people involved in the Olympic Games at the airport has accumulated 1460, and after customs testing, 40 people have been re-tested positive, of which 1 is an athlete and a team official, and the other 39 are from other stakeholders. The Beijing Winter Olympic Organizing Committee said that the inbound personnel and related staff of the Beijing Winter Olympic Games have implemented closed-loop management.
The countdown to the opening of the Beijing Winter Olympics ushered in the last 8 days, and scientific epidemic prevention has become an important prerequisite for running the Winter Olympics well. Different from the previous manpower-based service methods, "wisdom" will become the biggest highlight of the venues of this Winter Olympic Games.
During the "Meet in Beijing" ice hockey domestic test activity, the "multi-test intelligent terminal" digital sentinel, atomization disinfection robot, contactless logistics distribution cabinet, etc. have been unveiled, showing outstanding skills in information inspection, daily killing, dynamic inspection, distribution of materials and other aspects.

The digital sentinel of "multi-test-in-one intelligent terminal" is the "first line of defense" for epidemic prevention and control. It is understood that during the test match, in the south gate of the Wukesong Sports Center venue, the staff only need to scan a two-dimensional code that is, the epidemic prevention card against the terminal equipment at the door, and personal information such as my health information, vaccination and itinerary code will be displayed on the device terminal, up to 2 seconds, you can achieve rapid passage.
During the Winter Olympics, the luggage, sports equipment and food carried by athletes and accompanying people are a possible chain of transmission, how to avoid the spread of the virus through the items?
Jointly developed by Fuzhou University and Fuxia Technology, the "Cold Chain Logistics Ultraviolet Photocatalytic Compound Killing Machine" will play a role in the Winter Olympics. It is understood that 9 killing machines have been installed and debugged in the three competition areas of the Winter Olympic Games, and the luggage, sports equipment, supporting tools, food and other materials entering the Olympic Village and the Capital Gymnasium will be inspected and killed, so as to build a solid epidemic prevention barrier for the Winter Olympics.
In addition to the testing of people, objects, etc., how to detect the new crown virus in the environment inside and outside the Olympic venues?
"Compared with conventional methods such as throat swabs, it is very difficult to quickly detect the new crown virus in the air. The coronavirus is transmitted through aerosols in the air, and there has been no good way to collect aerosols. Because the content of viruses in the air is much lower than the content in the human body, and the new crown virus is an RNA virus, the stability is poor, and the air is always flowing, if it is delayed for too long, it will lose the significance of detection, which requires efficient sample collection and sensitive and accurate detection. Liu Peng, a researcher at the School of Medicine of Tsinghua University, said at the large-scale theme interview activity of the "Science and Technology Winter Olympics Enterprise Tour" jointly organized by the Propaganda Department of the Beijing Municipal Party Committee, the Beijing Municipal Science and Technology Commission and the Zhongguancun Administrative Committee on January 19.
In order to solve this problem, Liu Peng and his team have worked hard to develop and complete the nucleic acid detection system for the new coronavirus in public space bioaerosols. The system can collect and add new coronavirus particles from the air aerosol to the detection chip, and the test report can be issued in 45 minutes. This system is highly sensitive, 10 times more sensitive than conventional methods, and does not "pick" the strain, even the Omikeron strain can not escape.
