BHW01 Airport Border Security System
I. System Introduction
Tianjin Xinlong Airport Equipment Co., Ltd. as a domestic professional manufacturer of airport equipment, has developed an airport border security system based on optical fiber sensing core technology. This technology has been successfully applied in various sensitive areas such as South China Sea Underwater Detection Array, High-speed Rail Protection Network, Military Base, Power Energy, Public Security and so on. By laying sensor optical cable in the monitoring area, the monitoring area can be effectively monitored. When there is external intrusion, the sensor system identifies the intrusion type by detecting the interference signal characteristics of the light, and then gives an alarm. Sensor optical cable detection system and airport video, broadcasting, lighting and other systems constitute the airport border security management system. The system overcomes the shortcomings of high false alarm rate of existing similar systems, and can continuously update and improve the database in operation to further improve the accuracy and meet the security requirements of airports under various geographical and climatic conditions.

3. System Architecture
Airport border security system is mainly composed of five subsystems: optical fiber intrusion alarm system, video surveillance system, video display system, intelligent voice broadcasting system and vehicle license plate system.
1. Fiber-optic Intrusion Alarm System
The optical fiber intrusion alarm system obtains the illegal intrusion signal through the vibration optical cable, and feeds the intrusion signal back to the peripheral system alarm host through the communication optical cable. The host distinguishes whether the intrusion signal is a real malicious intrusion signal according to its own intelligent recognition algorithm. When an illegal intrusion occurs, the system sends the alarm information to the client of the monitoring software located in the central control room through the local area network, thus alerting the user to the alarm information, and linking up the relevant sound and light alarms.
2. Video surveillance system
Through cameras deployed in the monitoring area, the collected field images are transmitted to the central storage device through the field Gigabit ring network for video redundancy storage, and unified video surveillance management is carried out through the software of the video integrated management platform. When human intrusion occurs, the optical fiber intrusion alarm system can real-time and remote linkage related cameras for image capture and other operations. 。
3. Video Large Screen Display System
This system adopts ultra-thin wall, seamless stitching design, with built-in signal processing module, external image controller and control management software, to form a stitching display wall system with ultra-high brightness, ultra-high contrast, ultra-high resolution, high durability, high stability and ultra-strong signal display ability. It supports video, RGB and network signals to be stitched on the stitching display wall with single screen and M*N stitching. It can be widely used in various monitoring and command centers, video conference centers, advertisements and information publishing places.
4. Intelligent Voice Broadcasting System
This system adopts TCP/IP network technology which is widely used to transmit audio signals in LAN and WAN in the form of IP packet protocol. It thoroughly solves the problems of poor sound quality, complex maintenance and management, and poor interaction performance of traditional broadcasting system. The system is simple to use and easy to install and expand - only connecting the digital broadcasting terminal to the computer network can form a powerful digital broadcasting system.
5. Car License Plate System
The system is mainly composed of front-end data acquisition subsystem, network transmission subsystem and central management subsystem. The front-end data acquisition subsystem obtains the data of vehicle passing time, speed, picture, license plate number, body color and so on through video tracking and analysis technology. Data is transmitted to the central management subsystem through the network transmission subsystem. The central management subsystem manages, stores and shares data centrally.
IV. System Characteristics
Compared with traditional sensors, the sensing optical fibers used in this system have many advantages, including:
L Technical Advancement
Optical fiber perimeter security technology is the most advanced perimeter security technology in the world today. It is widely used in administrative agencies, military bases, airports and other important places in many countries. Especially for long-distance, large-scale perimeter with inherent good applicability.
Physical Preventive Separation
Using physical defense zone, the disturbance signals between different regions are independent of each other and will not interfere with each other. For the disturbance signals occurring simultaneously in different regions, the overlap of time will not lead to wrong judgment; the induction fibers in each region are not connected with each other, and the faults such as fiber breakage in one region will not affect other defense zones.
L All kinds of intrusion can be effectively monitored in real time
Climbing, overturning and destroying the fence;
Digging and drilling on the ground and underground;
The trampling and walking behavior in the clothing area without permission.
L High security level and low false alarm rateIntelligent intrusion mode discrimination can eliminate all kinds of interference factors; different levels of alarm demand response can be customized according to customer needs, system early warning or real-time alarm; for birds, small animals and other interference factors can be reduced to a minimum,
It can function stably and well under all kinds of climatic conditions.
Low energy consumption, strong environmental applicability
The sensing and communication components laid in the defense area are all optical cables without energy supply, and the whole defense area does not need electricity supply; the optical fibers and optical cables have stable performance, corrosion resistance, long-term use in humid climatic environment, green, clean, energy-saving, environmental protection, and good adaptability to wind, frost, rain, snow and other climatic conditions.
Good anti-jamming
The system uses optical fibers for transmission and detection, which determines its good anti-detection, anti-interference and anti-lightning strike, and does not interfere with and influence each other with various signal fields such as electromagnetic, radio frequency, wireless signal, high voltage electrostatic field and so on.
Free layout, concealment, harmony and beauty
It can be laid on fences, fences and other existing enclosures, or buried in concealment, free from terrain and environmental restrictions, not destroying the existing environment, harmless to personnel, fully embodies the concept of harmony and peace; optical cable is laid underground, hidden and difficult to detect, laying area width of optical cable is about 1.2 meters, larger than one-step distance of conventional people, to ensure no leakage of intrusion.
L Essential Safety
The system adopts passive working mode of defense zone. Except for the monitoring terminal located in the room, all the non-metallic devices used in the whole system do not produce any sparks. The optical fiber itself is not conductive and will not be damaged by lightning, static electricity and so on.
