Thermal imaging technology measures temperature in 1 second, personnel information is registered in “second”, alarm prompt is not worn when masks are used properly ... During the epidemic, with the advantages of AI, face recognition algorithms and other advantages, China has started a new model of scientific “epidemic prevention”.

"35.7 ℃, body temperature is normal." At Taiyuan Municipal Government Service Center in Shanxi Province, people entering and leaving the office building no longer need to wait and stay. At the scene, the real-time body temperature of each person will appear on the display screen when people entering and exiting pass the temperature measurement area. This device is similar to a video camera. As long as a person passes within five meters of the detection range of the lens, it only takes one second to know whether the body temperature is abnormal.
In the body temperature detection, the temperature figures of normal body temperature are green. Once the body temperature is detected to exceed 37.3 ℃, the screen temperature figures will be red, and a voice alarm will be issued at the same time, prompting the field staff to use the handheld terminal to guide the suspected body temperature abnormality to perform the composite body temperature. Test and register well to ensure foolproofness. "Since the installation of this system, not only has it saved labor costs for epidemic prevention, but it has also greatly improved the efficiency of testing," said a staff member of the Taiyuan Municipal Government Service Center.

This system is an infrared imaging technology temperature detection system developed by Jiahua Technology using thermal imaging and edge computing technology. It has been promoted and used to accurately complete the body temperature detection and over-temperature alarm when there is a large passenger flow. A line of security.
"The ID card personnel's information is registered in seconds. Citizens no longer need to register by hand. They only need to put their ID cards on the identifier to complete their identity capture, and record the time of visiting and leaving the hall." The staff of Taiyuan Municipal Affairs Service Center introduced that the new equipment and technologies introduced have greatly improved the efficiency of epidemic prevention work, achieved more accurate information, clearer destinations, wider traceability, and efficient and accurate warfare.
The personal information registration all-in-one machine automatically generates a visitor statistics table in real time, accurately grasps its residential address, entry time, measured temperature, and to-do items, etc., enables trajectory query, and cooperates with the community to carry out risk investigation, becoming a period of prevention and control of epidemics Important boost.
The newly installed "outbreak prevention and control AI monitoring and early warning analysis service" system in the Taiyuan Municipal Affairs Service Center uses the leading face recognition algorithm to develop a posture detection algorithm model for the mask wearing problem in the current period, covering a large area of masks and hats. It can accurately recognize even when the face is blocked.
When a person who does not wear a mask is identified, the system will autonomously issue an alarm sound indicating that the body temperature exceeds the standard, and at the same time track and display the position of the person on the screen, effectively reducing the risk of cross infection.
According to Jinhua Jiping, a research and development staff of Jiahua Technology, the system can support crowd recognition from street camera angles, gates, and other perspectives. Mask wear can be analyzed from the side of the face. After testing, the model accuracy rate is 99%. It has the ability to provide hundreds of channels for simultaneous analysis and processing, and the analysis results respond in seconds.
The system can be quickly deployed in railway stations, airports, bus stations and other key transportation hubs and urban densely populated places such as shopping malls, office buildings, campuses, and communities. It can carry out early warning of epidemic conditions and rapid and accurate detection of passersby, and realize intelligent identification without wearing masks. Crowds gather early warning to reduce potential safety hazards in public places.
Since the outbreak of the epidemic, a number of Chinese enterprises have accelerated their scientific and technological research and, with the help of artificial intelligence technology, developed a number of scientific and technological achievements in combating the "epidemic" to improve the efficiency of epidemic prevention and control. Beijing, Guangdong and many other places have used epidemic prevention "high-tech" such as drones, face recognition thermometers, and AI recognition to help prevent and control the epidemic, and the "war" epidemic has become increasingly intelligent and digital.
