System Introduction
The vibration fiber optic alarm system uses optical cables as sensing units, and the vibration fiber optic host collects, analyzes, and processes the vibration signals of the front-end optical cables. Due to the characteristics of optical cables, the system can achieve detection of long-distance and large-scale perimeter defense zones, with each defense zone ranging from hundreds of meters to kilometers in length.
The system can be divided into fence type and buried type according to different practical applications. It can be applied to various types of surface fences such as wrought iron, wire mesh, fences, and walls, as well as to lawns, gravel layers, cement floors, and ordinary soils.
The system is particularly suitable for places that are flammable, explosive, and have strong electromagnetic interference, such as liquefied gas plants, dangerous goods warehouses, military goods warehouses, etc; It can also be used for the prevention of key facilities and areas, such as anti-theft of power facilities, anti damage of oil and gas pipelines, airport perimeter prevention, and border intrusion prevention.System Composition
The vibration optical fiber alarm system is composed of intelligent control host, alarm software, signal acquisition equipment, linkage equipment, optical cable transfer box, switch, defense division package, guidance optical cable, and vibration sensing optical cable.
External vibrations, pressures, etc. can cause deformation of the fiber optic cable vibration sensor or vibration cable, and changes in the optical path can lead to changes in the optical signal transmitted by the vibration cable. The collector detects changes in light signals, processes the detected signals, and extracts the characteristic values of intrusion signals. When the characteristic values meet the alarm conditions, an alarm signal is output.System Features
Screen display: 2.5-inch screen human-computer interaction system, which can intuitively view signal values and operation setting parameters.
Multi level networking: The collector can cascade multiple devices and form a multi-level management system with intelligent keyboards and management platform software.
Intelligent analysis: The device can intelligently analyze wind, rain, other vibrations, and human intrusion.
Software operation: The front-end can be deployed/disarmed, and its output parameters and configurations can be adjusted through intelligent debugging software.
One cable structure: The host is placed indoors with a one cable wiring method, and no power or communication lines need to be laid within the perimeter protection range.
