Como usar o sistema distribuído de monitoramento de vibração de fibra óptica para segurança perimetral-INNO

O fiber optic cable vibration detection and alarm device is the latest perimeter alarm system successfully developed and put into use by FJINNO。

The optical cable vibration detection and warning device includes an optical cable vibration detection host, a wind and rain vibration detection ring, a linkage host, a buzzer, a main control keyboard, a vibration sensing device, and a buckle net. The wind and rain vibration detection ring is connected to the optical cable vibration detection host, the linkage host is connected to the optical cable vibration detection host and the buzzer respectively, the main control keyboard is connected to the optical cable vibration detection host, and the vibration sensing device includes a vibration optical cable, a collector, and an optical cable terminal box. Uma extremidade do cabo óptico de vibração é conectada ao coletor e à rede de fivela, respectivamente, a outra extremidade do cabo óptico de vibração é conectada à caixa terminal do cabo óptico, e a caixa terminal do cabo óptico é conectada ao host de detecção de vibração do cabo óptico.

Este sistema usa cabos ópticos como unidades de detecção e detecção, que pode alcançar alta sensibilidade, perímetro longo, e proteção perimetral em grande escala. É muito adequado para requisitos de prevenção de intrusões em aeroportos, empresas químicas, oleodutos, ferrovias, áreas residenciais, e várias áreas-chave. Depois de anos de pesquisa e desenvolvimento, nossa empresa desenvolveu um sistema de alarme de vibração de cabo óptico de alarme falso anti-vento e chuva.

Cabos ópticos de vibração tipo barramento são colocados ao longo do perímetro, and the optical path structure of the defense zone separation box is used to achieve defense zone division. One set of bus type optical cable vibration alarm host can carry 35 defense zones on its own, and multiple bus type hosts can be stacked at the same time.

The system uses ordinary communication grade optical cables as vibration cables, which have advantages such as anti magnetic, anti lightning, anticorrosão, impermeável, and UV protection. The system uses high-speed chips to analyze and process signals, which can effectively eliminate various interferences. Taking into account the numerous advantages mentioned above, it is currently the only new generation of automatic wind and rain vibration detection and processing perimeter alarm product in the world.

The most important part of this system is the wind and rain vibration detection ring. The vibration signals generated by strong winds, light winds, chuva forte, and light rain are sent to the detection system through the wind and rain vibration detection ring for automatic and accurate judgment. The judgment signal is used to control the ‘size’ of the seismic event in the defense zone, thus achieving accurate judgment of the alarm signal at all times.

Important features of vibration optical cable monitoring system:

1. The system uses single-mode communication fiber as the sensing unit, which is lower in cost and easier to maintain compared to similar products, achieving long-distance and large-scale detection of perimeter defense zones;

2. The maximum distance for different types of defense zones varies. For the large bus type, the maximum length of each defense zone optical cable is 1500 metros, for the precise positioning type it is 50 quilômetros, for the dual defense zone and network type it is 1000 metros, for the popular type it is 200 metros (dedicated optical cable), and for the airport specific type it is 1000 metros.

3. Easy to construct, no need to dig cable trenches, just lay directly; (Without damaging the foundation or lawn, it can reduce significant construction costs)

4. Forte capacidade anti-interferência, such as wind and rain vibration, construction vibration, car vibration, train vibration, and aircraft takeoff and landing vibration, can be conveniently and flexibly set to shield the signals generated by these vibrations;

5. Using fiber optic as a passive detector effectively avoids lightning interference and has lightning protection function. Suitable for flammable, explosivo, and strong electromagnetic interference environments;

6. Suitable for various complex terrains, capable of detecting irregular perimeter defense zones;

7. Fiber optic cables have high sensitivity and can be directly laid on various iron grids, iron crafts, plastic steel, brick walls, and irregular fences, as well as buried underground to form concealed protection systems. Directly prevent criminals from crossing over and invading, damaging walls and stepping into areas;

8. Any obstructions such as birds, grass vines, etc.. do not affect the normal operation of the system;

9. Long service life and low maintenance costs;

10. The alarm host will not affect the overall system response speed due to the expansion of linked devices;

11. The automatic detection function for wind and rain greatly reduces errors and missed reports;

12. The defense zone can be infinitely expanded, Atendendo plenamente aos requisitos de proteção antifurto de perímetro de longa distância e grandes áreas;

13. O teclado e o computador para armar e desarmar podem ser usados simultaneamente, or separately;

14. O próprio software de alarme pode extrair o sinal de vídeo da zona de alarme;

15. O software de alarme pode extrair sinais de vídeo da zona de alarme mesmo em estados sem alarme;

16. Adotando chipsets de nível militar e industrial, adequado para vários ambientes agressivos;

17. Obtendo informações livres de cobre, com um consumo de energia de apenas 60-80 watts por 100 quilômetros, atende plenamente aos requisitos de conservação de energia e proteção ambiental.
