What are the high technologies of the Winter Olympics?

As follows:

1. Robot dog inspection to ensure the power of the Winter Olympics

Considering the risks of epidemic prevention and control, in the Yanqing competition area, robot dogs and prevention Drones are used to inspect the venue's power facilities instead of manual inspections. Both types of equipment are equipped with 3D imaging and infrared detection devices to quickly capture abnormal conditions of power equipment. At the same time, through 5G communication, the operating status of on-site equipment is quickly transmitted to the command center. At the same time, it also solves the complex mountainous environment and limited conditions in the Yanqing competition area. Under space conditions, manual inspection is difficult.

2. Smart body temperature patches can be used for 24-hour real-time monitoring

Epidemic prevention measures in various venues have adopted various technological means. Beijing has promoted the application of many technological achievements in body temperature monitoring, environmental disinfection and other aspects by organizing technological research on scientific and technological epidemic prevention, expert demonstrations, and on-site testing.

The public space aerosol new coronavirus monitoring system can realize virus monitoring, early warning and rapid detection of the air in the venue. The detection sensitivity is three times higher than traditional detection methods. At the same time, it is used in the National Speed ??Skating Hall, Ice Arena Cube and other venues have conducted relevant tests. In addition, multi-sign sensing devices based on open source chips, edge computing and other technologies have also been developed.

3. Conduct "nucleic acid testing" of the air in the venue

In order to monitor aerosols in the air, Tsinghua University, Peking University, Institute of Pathogen Biology, Chinese Academy of Medical Sciences, and Changping Experiment The laboratory and other scientific researchers carried out urgent research and jointly developed a public space bioaerosol new coronavirus monitoring system. Currently, multiple sample collectors are already on duty at multiple venues of the Winter Olympics.

Compared with conducting nucleic acid testing on people, conducting "nucleic acid testing" on the air is not easy. Due to the large volume of aerosol samples, the viral load in the air is relatively low, far lower than direct sampling from the human throat. At the same time, the stability of viral RNA is poor, which requires the collection method to be efficient and the detection method to be very sensitive.

4. "Generation, charging and storage" integrated charging station

The National Alpine Ski Center has low cold, snow, large temperature differences, complex terrain, etc. in the Winter Olympics power supply environment. Characteristics pose “low temperature” challenges to the normal operation of power equipment and the real-time guarantee of operation and maintenance personnel.

To this end, State Grid Beijing Electric Power has vigorously promoted key technology research, combined with the actual needs of the Winter Olympics power supply guarantee, and innovatively developed new technologies and new equipment suitable for the characteristics of the Winter Olympics power supply. The "issuing, charging and storing" integrated charging station located in the Yanqing competition area is one of them.

He Yanbin, director of the development planning department of State Grid Beijing Yanqing Company, introduced that the State Grid Winter Olympics comprehensive demonstration station for generation, charging, storage and discharge is a national key research and development project "a smart grid comprehensive demonstration project to support the low-carbon Winter Olympics" One of the topics adopts the most advanced AC and DC hybrid distribution network technology in China.

5. Cloud broadcast interviews can realize remote conversations

As one of the three key layout industries of the Winter Olympics in science and technology, cloud broadcast will replace the asset-heavy, high-threshold traditional broadcast with lightweight cloud broadcasting. ization, through cloud-based acquisition, editing and broadcasting technology, cloud-based broadcast equipment and remote personnel services have been achieved. In addition to the on-site camera equipment, all director production is completed in the cloud. As long as there is a network, the director can use a laptop to connect to the cloud from anywhere to complete signal production.

The front-end of the cloud broadcast system not only supports signal collection from professional broadcast-level cameras, but also supports mobile phones, non-professional camera equipment, etc., and also supports access to streaming signals from other systems. The on-site signal is transmitted back to the cloud through 5G, where the production is performed and the final broadcast signal is distributed to multiple platforms. Dual cloud equipment also provides reliability guarantee. Through cloud production, we provide professional live event photography, directing and audio mixing technical services.
