The application of video surveillance intelligent analysis technology in airport security system

In 2019, Beijing Daxing International Airport entered the official flight. As a global super-large smart airport built with international standards, Beijing Daxing International Airport has widely applied various smart new technologies, such as big data analysis, artificial intelligence, and smart video analysis. Biometric identification of entrance and exit control technology, etc.

In the "Guiding Opinions on Promoting the Construction of New Infrastructure in the Transportation Field" issued by the Ministry of Transport this time, it is proposed to create a smart airport with data sharing, collaborative efficiency and intelligent operation for smart civil aviation. Encourage the application of intelligent operation equipment and make breakthroughs in intelligent operation monitoring, intelligent video analysis and other fields.

With the rapid development of public transportation, air travel has become a convenient and fast travel choice for people, and airports have become a public place that has attracted much attention. The airport has the characteristics of wide area, scattered flow of people, and quicker collection and distribution, which increase the difficulty of airport security construction.

Airport security needs video surveillance

Security construction has always been an important gate for airport security work. When people are full of expectations for this fast-paced mode of transportation, it also imposes more pressure on airport security. At this stage, in the construction of airport security, the general security system mainly refers to the video surveillance system, the access control system and the perimeter alarm system. The video surveillance system is an important part of the airport security system.

Large-scale international airports are generally monitored by the main runway, terminal building, air traffic control center, cargo center, fire center, garage, aviation food factory, property building, border inspection building and other areas. The aviation hub airport has a large area, a large flight area, a large terminal building, a large passenger and cargo flow, and a large amount of aircraft taking off and landing. It requires a wide range of monitoring areas. In such a large area, it is necessary to rely only on human management and control. Send a large number of staff to be on duty, stand guard, patrol, and inspect, but also pay attention to overcome the problems caused by many human factors, climate factors, and environmental factors (many corners and corners and places that are inaccessible or inaccessible to people). It can be said for sure There will be many phenomena that cannot be prevented.

Integrating AI technology video surveillance to land in a smart airport

Video surveillance intelligent analysis technology has been applied to the construction of airport security monitoring system in 2013, in the loss of items, personnel wandering, prohibited * mixing line, perimeter intrusion, face recognition, access control and surveillance video composite, fire and surveillance The application of technologies such as linkage alarm has become mature.

From the perspective of technical application, the high-definition of airport security is an inevitable trend. Although Beijing Daxing International Airport has not announced the airport’s security plan, judging from the use of all-digital video surveillance systems in airport security construction such as Capital Airport T3 and Pudong Airport T2, digital high-definition video surveillance has become a solution for airport security video surveillance. Video surveillance with higher pixels such as 1080P and 4K has gradually been widely used in airport security.

With the development of technology, the airport has gradually begun to adopt some practical, performance and relatively stable intelligent functions, such as face recognition, in accordance with its own needs. Face recognition technology has reached maturity and has been widely used in the security field. It can be used to identify criminals and track the whereabouts of key people through gun-ball linkage.

As a public place with tens of thousands of passengers entering and leaving every day, effective management of passengers is also crucial. Some domestic security companies combine high-definition video surveillance with intelligent analysis technology in airport security applications, and use facial recognition, electronic passports and other technologies to monitor each area and identify each passenger in time.

Its security system supports a built-in database that stores up to 30,000 facial images, which helps the camera achieve real-time face capture and comparison. Once a suspicious person is discovered, it can not only issue an alarm but also continue to track it. In cutting-edge airport solutions, AI technology can be seen everywhere.

Aiming at the unique security system of the airport, starting from the three aspects of vehicles, personnel, and luggage, it can also create a set of security solutions covering different areas such as airport roads, parking lots, lounges, check-in counters, airport runways, aprons, etc. .

The surveillance and alarm system around the airport uses panoramic cameras to provide 180°, 360° full video scenes, bringing people a new real life and interactive experience, and the surrounding area of ​​the airport is covered by a thermal imaging pan/tilt camera. Once someone crosses the boundary, it will immediately Detected and issued a warning.

Video surveillance improves emergency response and operation management efficiency

In addition to individual advanced technologies, the construction of smart airports also requires video surveillance systems to play a role in emergency handling, operation management, and other aspects.

Centralized command to improve emergency response efficiency

Build an efficient security command center based on the video surveillance management platform, and incorporate the main parts and areas of the airport into the command center for unified management. This is conducive to giving full play to the benefits of the entire security system when emergencies occur. The unified command and dispatch of departmental resources can effectively control the impact of emergencies and improve the efficiency of emergency response.

Technology integration improves operational efficiency

The command system, departure system, baggage system, and security inspection information analysis system form a more intelligent security business system through the integration and integration of various technologies to provide security for the airport’s various production services and enhance the airport’s emergencies Emergency response capabilities.

Stable storage of video surveillance data

The airport is a highly sensitive field that cannot afford accidents. Once an incident occurs, the retrospective video recording of the incident is crucial. This requires that the video storage at each monitoring point of the airport must be very stable, and there should be no loss or leakage. Therefore, when designing a video storage system, high stability and reliability need to be considered.

Intelligent system operation and maintenance management

Due to the high security requirements of the airport, when equipment fails, the system should be able to detect and find in time, and provide fault location information. Therefore, it is necessary to deploy an intelligent operation and maintenance management system to effectively manage the equipment in the system, realize the intelligent detection of the video surveillance system, effectively improve the operation and maintenance management efficiency of the video surveillance system, reduce the system failure rate and the operation and maintenance cost, and ensure the timely maintenance In place.
