What high technologies were used in the Winter Olympics?

1, temperature monitoring technology of "underarm band-aid": epidemic prevention and control "clairvoyance"

Epidemic prevention and control is the top priority of Beijing Winter Olympics. A "band-aid" the size of a mobile phone card plays an important role in epidemic prevention and control-taking temperature. This smart thermometer is also called "underarm band-aid". The staff only need to stick the smart thermometer on the skin and display the temperature data changes in the mobile phone applet. Stick it on the body after charging, so that we can monitor the temperature of each worker in real time, and once it exceeds the standard value of 37.3℃, it will automatically call the police. Therefore, it is also known as the "clairvoyance" system for epidemic prevention and control.

2, dry blood point detection technology.

In order to maintain the Olympic spirit of fair competition, the detection method of dried blood spots will be used for the first time in this Winter Olympics. Detection of dried blood spots is a new technology for collecting biological samples. By collecting whole blood samples on cardboard, the samples can be stored and analyzed later. Compared with the traditional blood test and urine test, the detection of dry blood spots has the advantages of small blood collection, convenience and reliability, and stronger sample stability, and will become a powerful means to crack down on doping offenders in this Winter Olympics.

3, 5G 4K/8K super Gao Qingyun broadcasting equipment: more realistic.

At this year's Winter Olympics, the 5K4K/8K super-Gao Qingyun broadcast is also one of the key projects of "Technology Winter Olympics". In order to better present major events to audiences all over the world, 8K ultra HD live broadcast technology will be applied to this Winter Olympics for the first time. The 8K ultra-high-definition live broadcast technology mainly realizes the high-definition live broadcast of sports events by means of high-speed transmission of 5G signals, real-time editing of live collection and broadcast by 8K cameras, and signal transmission of 6C communication satellite of China satellite. Compared with previous Olympic Games, the 8K ultra-HD live broadcast technology adopted in Beijing Olympic Games can show more details, enhance visual impact and realistic experience, and cover a wider area, thus truly realizing the global viewing of the Olympic Games.

4. Preparation of direct drinking water by pure physical water purification technology: avoid the harm of "chlorine" to human body.

In order to ensure the water safety of Olympic venues and surrounding residents, pure physical water purification technology was used to prepare direct drinking water in this Winter Olympics. It is reported that the preparation process of this kind of direct drinking water realizes the disinfection and purification of drinking water by physical means such as volcanic rock filtration, and the obtained water quality meets the highest international drinking water standard. At the same time, compared with the traditional process, the process also has the advantages of energy saving and water saving, and can effectively avoid the harm of chlorine to human body in the traditional process.

5. Carbon dioxide refrigeration system: carbon emission is close to zero.

Environmental protection is one of the main attractions of this "Science and Technology Winter Olympics". In addition to the well-known use of hydrogen energy vehicles and 100% "green electricity" power supply in the venue, the most striking thing is the National Speed Skating Hall called "Ice Ribbon". 1 19 1 Precast members are coded by grandstand arc prefabrication technology. On the ice surface of 65,438+2,000 square meters, the independent and accurate temperature control is realized by using the environmental protection refrigerant CO2 refrigeration technology and refrigeration mode, so that the whole stadium can operate at the same time and be used differently.
