Civil aviation security market characteristics and development

In recent years, with the growing paralysis of terrorist activities in the world, the work of safety prevention in the field of civil aviation has increasingly attracted close attention from all sectors of society. How to build and manage a complete set of modern security systems that are technologically advanced, reliable, and can minimize aviation flight safety accidents has become a very important part of the daily work of all airports and airlines. The matrix switches the image and controls the camera. The image is displayed on the display device. The personnel on duty monitor the airport's business operations closely through these images, and at the same time, save the video and save these images so that in the event of an accident, they can look for the relevant clue by watching the video.

Civil aviation is a three-dimensional service system from the ground to the air. It is mainly composed of subsystems such as air transport services, air traffic services, and airport services. It covers planning, organization, and coordination in various fields such as flight, maintenance, ground support, and air traffic services. And command, and subject to the influence of environmental and social environment.

The access control system mainly undertakes the management functions for the entry and exit of personnel entering and leaving the airport. Through the card reading equipment installed at the entrance and exit points, the person passing through the passage can be qualified to determine whether to release the document, and the person entering and leaving the document can be recorded in the database. The standard communication protocol is compatible with the mainstream products of well-known domestic and foreign manufacturers. It integrates software through the network layer instead of simple hardware linkage.

In recent years, with the rapid development of computer technology, multimedia technology, digital image compression technology and network applications, network video surveillance technology has increasingly become an important means of image processing in television monitoring systems. Its working mode is different from analog CCTV monitoring system and digital video monitoring system. It fully supports networked operation, but it also supports analog CCTV monitoring system working mode, supports upgrading from analog system to networked system, so as to ensure that the user's previous investment does not appear waste. Once the network video surveillance system emerged, it used its advanced concepts and powerful functions to make up for the deficiencies of analog CCTV systems and digital video surveillance systems, and received extensive attention in the construction of airports in the field of civil aviation. According to the planning of the National Civil Aviation Administration, the management of civil aviation airports has entered the age of information and networking. The image resources of the surveillance system have been transformed from the original view of the duty personnel on the airport operation status to an important information source for airport management. This information source will be widely used in the future management work and will be used for secondary development.

The network video surveillance system utilizes the standard LAN/MAN/WAN/Internet as the backbone for transmitting video, audio and data. The video front-end can be conveniently located anywhere on the network. And video images can be flexibly received at any location on the network, instead of only seeing the images locally as before, using network technology, live video images can be sent anywhere. The system is powerfully flexible and expandable. The network video surveillance system uses open standard protocols and networks for communication. This allows the system to have a wide range of compatibility and high integration. Devices of different manufacturers can be used in one system. This reduces the investment in equipment for users. The risks and convenience of system upgrades.

The Capital Airport Terminal T3 is currently the largest airport terminal in China with a building area of ​​more than 1 million square meters and is the third largest airport in the world.

The T3 terminal's security system adopts an unprecedented large-scale networked digital surveillance system. It has become a representative project for a single security system in China and even in the world, both in terms of system scale and technological advancement. The T3 security system adopts a distributed architecture design. It is characterized by scattered risks, load balancing, and mutual backup of system devices. The video signal is accessed in the nearest place and stored in a decentralized manner, which reduces the requirement for trunk bandwidth. The entire security system includes five subsystems: digital video surveillance system, access control system (including anti-theft alarm) system, security dedicated 10G network system, security integrated system and storage system.

In the civil aviation security market, networking and digitization will test the future development trend. More and more, the airport will choose digital security systems. The core technologies involved in this system are digital video surveillance, network transportation, network storage, perimeter alarm with high precision and high reliability, intelligent access control and biometric identification technology, image analysis technology, and comprehensive security management platform.
