On April 25th, the new AI human security instrument was released at the 35th Institute of China Civil Aviation Science and Technology. It announced that the performance index of this security instrument equipped with an artificial intelligence processor has reached the international advanced level.
HiSC Human Security System is a new generation of human security products independently researched and developed by China Aerospace Science and Industry No. 3 Institute of Aerospace Science and Technology. The HiSC system realizes non-contact three-dimensional imaging of human body with millimeter wave technology and completes hiding under human clothing. A comprehensive inspection of hazardous materials/prohibited items and the use of computer vision analysis technology to effectively protect human privacy. The product has passed the human body radiation safety testing of the national authoritative department, which combines security and comprehensive security. The system three-dimensional holographic imaging, hidden objects Automatic labeling, human intelligence privacy protection, key technologies such as broadband frequency source and microwave transceiver system have reached the world advanced level of similar products, and obtained more than 40 national invention patents.
The safety instrument performance is eye-catching. No radiation security system, millimeter resolution, 0.7 seconds of reading speed, up to 95% detection rate, performance indicators are the first in the country.
Most friendliness: No radiation, no invasion of privacy
This security tester, which has invented and used new-type patents in more than 40 countries, is the first in China. The system is different from the current universal human security inspection equipment. At present, the human body security inspection methods commonly use magnetic metal detection plus artificial hand detection mode. The biggest drawback is speed. Slow labor intensity, and a small number of places using X-ray human security instrument, will cause radiation damage to the examinee. And the space security instrument is an absolute advantage in efficiency and radiation safety. Its built-in antenna can capture human skin Millimeter wave reflected from the surface, the electromagnetic radiation is less than 0.00014mW/CM2, the radiation amount of a security inspection is only one thousandth of the mobile phone signal.
In terms of detection ability, the subject only needs to stand on the security tester and raise his hands. Within 2 seconds, the security door can read all the information except for the skin of the subject, 360°, and the imaging resolution is in the order of millimeters. The map is instantly generated. The non-metallic dangerous goods, including corrosive, flammable and explosive liquids, gels, etc., which cannot be detected by the current security inspection equipment, are prohibited.
However, this kind of 'overview' is only for items. According to 35 designers, in order to protect the subject’s privacy, the security instrument adopts intelligent privacy protection technology, and the imaging record shows the human face and gender organs in a blurry manner. Virtual human mapping technology is used to display virtual figures on the screen on the outside of the security instrument. If there is any contraband, the logo will be made in the corresponding area of the doll. Privacy and security are guaranteed.
The smartest: IQ first, continuous learning
The most eye-catching performance at the press conference came from the first exposure of space AI technology. It is reported that although the proportion of similar products in the domestic market has exceeded 90%, the product was still one of the top international automatic identification technologies for dangerous goods a year ago. There is a gap in the level. In order to sit steadily in the country, the 35th carried out the automatic identification of dangerous goods technology. Experts from the China Artificial Intelligence Industry Development Alliance led the use of artificial intelligence technology for automatic identification of dangerous goods.
This round of research called 'brain change' has increased the automatic identification rate of dangerous goods for security devices to 95%, and the automatic identification time has been reduced to 0.7 seconds. In other words, 89 types of dangerous goods samples can be identified within one second. , And map the results to the virtual doll, marking the product far exceed domestic similar products, reaching the international top level.
'Domestic security products, IQ first', artificial intelligence experts expressed confidence, welcome from all walks of life test and challenge.
This 'best-brain' security tester is equipped with superior learning capabilities and can continuously learn from the endless variety of contraband products. The upgrade of the software platform can meet the needs of future security upgrades. The upgrade service is also very convenient. , No hardware changes, 'simple as mobile APP upgrade'.
Most professional: From military security to service livelihood
It is reported that as the backbone research institute of China's missile weapons, the 35th Aerospace Institute has actively participated in the military-civilian integration. In the civilian industry, it focuses on security and information, and oil and geology.
As the most typical military-civilian fusion product, the AI security instrument is supported by many of the leading advanced industries in the country. From structural design to radar detection, from image recognition to artificial intelligence, all core technologies are transformed from military technologies. Has a completely independent intellectual property rights. Although it is a civilian product, but from product design to production, they all adhere to the military high quality, high reliability standards.
'Knock on the blackboard, focus on the key'
Finally, we must sum up, the AI human security instrument unique three major product advantages, four innovative technologies.
Three product advantages: advanced, comprehensive, and safe
advanced ——The HiSC system can achieve greater coverage of hazardous materials, health and safety, and specific forms of expression through active millimeter-wave imaging systems. The imaging is clear and the inspection efficiency is high.
comprehensive - The HiSC system allows full inspection of all types of metal/non-metal guns, explosives, basic weapons, corrosives, flammable liquids, gels, drugs, cash, media data and other contraband.
Safety - The HiSC system emits no particles, and the amount of electromagnetic radiation is only one thousandth of the mobile phone.
Four innovative technologies: hologram, array, logo, privacy
holographic -Three-dimensional holographic imaging technology . The HiSC system scans the human body once, enabling 360-degree rapid imaging. The image resolution is in the order of millimeters. The information is rich and comprehensive.
Array -Array signal processing technology HiSC system adopts electric scanning sensor array, high stability servo control, stable and efficient security inspection processing with ultra-high speed signal processing system.
Marked -Hide items automatically marked . HiSC system utilizes advanced computer vision analysis technology to automatically mark objects hidden in human clothing to improve detection efficiency and efficiency.
privacy -Intelligent Privacy Protection Technology The HiSC system adopts the human body privacy intelligent fuzzy display technology, and the virtual human mapping display technology realizes comprehensive, strict privacy protection for the testee without worries.

Focusing on 35 areas in the field of security, in recent years, many types of security products have been developed to serve the national economy and the people's livelihood, and have gradually been put into the market. With the upgrading of the domestic security situation, the public’s attention to civil security has also increased. 35 security inspections Instrument products have been used in many domestic courts, prisons, ports, etc., and have been tested in airports in Beijing, Xinjiang, Hainan, and Guangzhou, and have received favorable reviews for their innovative security effects and experiences.
It is reported that civil aviation millimeter-wave security inspection standards will also be issued in the near future. The domestic airport security inspection equipment will be fully replaced. Aerospace science and technology will serve civil aviation security, and the era of smart security will come to an all-round end.
