Winter Olympics opening ceremony technology highlights are as follows:

1, machine dog inspection, safeguard the Winter Olympics power

Considering the risk of epidemic prevention and control, in the Yanqing race area, the machine dog and collision avoidance drones will be used to replace the artificial power facilities of the venues for inspection. Both types of equipment are equipped with 3D imaging and infrared detection devices to quickly capture abnormalities in the power equipment, while quickly transferring the operational status of the on-site equipment to the command center through 5G communication, as well as solving the problem of the difficulty of manual inspection under the complex mountainous environment and limited space conditions in the Yanqing race area.

2, intelligent temperature stickers can be 24-hour real-time monitoring

Each venue epidemic prevention initiatives have taken a variety of scientific and technological means. Beijing through the organization of scientific and technological anti-epidemic technology research, expert demonstration, on-site testing and other forms of body temperature monitoring, environmental disinfection and other links, to promote the application of a number of technological achievements.

Public **** space aerosol new coronavirus monitoring system can be realized in the arena air virus monitoring and early warning and rapid detection, detection sensitivity than the traditional means of detection increased by 3 times, while in the National Speed Skating Pavilion, the Ice Cube, and other venues for the relevant tests. In addition, it has also developed multi-signs sensing equipment based on open-source chips, edge computing and other technologies.

3, to the air in the arena to do "nucleic acid detection"

In order to monitor the aerosols in the air, Tsinghua University, Peking University, the Chinese Academy of Medical Sciences Institute of Pathobiology, Changping Laboratory and other scientific researchers to carry out urgent research, jointly developed a public ****space bioaerosol new coronavirus monitoring system. At present, more than one sample collector has been in the Winter Olympics a number of venues "on duty".

Compared with the nucleic acid test for people, it is not easy to do a "nucleic acid test" for the air. Due to the large volume of aerosol samples, the viral load in the air is relatively low, much lower than the direct sampling from the human throat, at the same time, the stability of the viral RNA is poor, which requires the collection method to be highly efficient, detection methods to be very sensitive.

4, "hair charging, storage and discharge" integrated charging station

National Alpine Ski Center in the Winter Olympic power supply protection environment with low cold, snow, temperature difference, complex terrain and other characteristics of the normal operation of power equipment, operation and maintenance personnel in real time to ensure that the "low-temperature" challenge.

To this end, the State Grid Beijing Electric Power vigorously promote the key technology research, combined with the actual needs of the Winter Olympics power supply protection, innovative research and development of new technologies, new equipment suitable for the Winter Olympics power protection characteristics. The "hair charging, storage and discharging" integrated charging station in Yanqing is one of them.

The State Grid Beijing Yanqing company development planning department of any Yanbin introduction, the State Grid Winter Olympic hair charging storage and discharging integrated demonstration station is the national key research and development program project "support low-carbon Winter Olympics smart grid integrated demonstration project" one of the topics, the use of the country's most advanced AC and DC hybrid distribution network technology.

5, cloud broadcast interviews can realize the dialogue

As one of the three key layout industries of the scientific and technological Winter Olympics, cloud broadcasting will be heavy assets, high threshold of the traditional broadcasting lightweight cloud, through cloud-based acquisition, editing and broadcasting technology to achieve the broadcasting equipment cloud and personnel services remotely. In addition to on-site camera equipment, all guide cutting production is completed in the cloud, as long as there is a network, the guide staff will be able to use a laptop in any location to connect to the cloud to complete the signal production.

The front-end of the cloud broadcasting system not only supports signal acquisition by professional broadcast cameras, but also supports cell phones and non-professional camera equipment, as well as other system streaming signal access. The on-site signals are backhauled to the cloud through 5G, produced in the cloud, and the final OB signals are distributed to a variety of platforms, while reliability is guaranteed through dual cloud devices. Professional live event camera, guide and mixing technical services are provided through cloud-based production.
