Features of vibration optical fiber alarm system:
1. Adopting vibrating optical cable as the front-end defense zone sensor, adopting pattern interference detection technology, the entire perimeter or detection area does not need power supply, no electromagnetic radiation, will not be attacked by lightning, and will not be interfered by other electromagnetic fields itself;
2. Using special vibration sensing optical cable as sensing optical cable, a single machine can meet a large perimeter of several kilometers.
3. The system engineering construction is very simple, and the overall construction cost is very low. It is suitable for working in various terrains, and is not restricted by the terrain, such as high and low terrain, twists, turns, and bends. It realizes detection of irregular perimeter defense areas without dead angles, breaking the traditional infrared, microwave walls, etc. It is only suitable for viewing Limitations of use in distances and flat areas; suitable for the installation of various iron fences, guardrails, barbed wire and fences to achieve protection of various irregular perimeters.
4. As the detection source adopts optical cable, it has the characteristics of high strength, good toughness, cold resistance, abrasion resistance, oil resistance, high temperature resistance, water resistance, aging resistance, and harsh weather resistance. At the same time, it has high water resistance, moisture permeability, cold resistance, and UV resistance. And other excellent functions. It is suitable for working in various harsh environments and is not affected by natural factors such as high temperature, low temperature, strong light, dust, rain, snow, fog, frost, and small animals.
5. The equipment adopts modular design, good stability, low maintenance, and low false alarm rate. Various data and alarm information are displayed in real time, with a friendly interface and simple operation.
6. The host of the optical fiber vibration early warning system is installed in the monitoring center. Only the front-end module of the defense zone, the terminal module of the defense zone and the vibrating optical cable are all passive devices on site. The main unit is connected to each defense zone with ordinary communication optical cables.
7. The optical fiber vibration early warning system can be equipped with multimedia software, with local graphic display, linkage alarm function, electronic map function, linkage control on-site alarm, video and other functions.
8. The optical fiber vibration early warning system host has a standard network interface, USB interface, etc., each host's IP address can be set, and the connection with the multimedia alarm server is realized through Ethernet. The alarm software can manage multiple system hosts. It forms a large perimeter alarm system of the defense zone type.
9. The optical fiber vibration alarm system host can provide corresponding switch output signals at the same time, so as to connect to third-party software or third-party standard alarm host.
Optical fiber vibration alarm systems are currently used in community perimeter security, villa perimeter security, oil depots, large-scale World Expos, sports meets, some companies and other large perimeters, and some smart prison projects are also used.
Advantages of vibration optical fiber alarm system:
1. Long defense zone distance is reflected in the sensor configuration: each defense zone can be up to 1000 meters in length, and the recommended length is 50-100 meters (depending on site conditions)
2. Strong transmission signal: optical fiber link loss is less than 5db
3. Acceleration sensing accuracy: 1m/s2
4. Alarm reliability: After 20K tests, 0 missed reports and 0 false alarms for a single event
5. Alarm system response time: less than 1s
