Vibration fiber optic alarm system application range
The vibrating cable perimeter warning system can be applied to places such as flammable, explosive and strong magnetic interference, such as liquefied gas plants, dangerous goods warehouses, chemical plants, military supplies warehouses, etc., and can also be applied to the prevention of key facilities and areas, such as Electronic facilities anti-theft, oil and gas pipeline anti-vandalism, urban railway signal line anti-theft, Olympic village perimeter prevention, airport perimeter prevention, border line anti-intrusion, etc., can also replace traditional precautions for ordinary perimeter places, Such as waterworks, residents living in the community, villa community and other perimeter places!
Vibration fiber optic system takes sensing fiber optic cable as sensing unit to monitor and control the vibration signals of Vibration Fiber in real time and continuously by touching directly or passing through the carrier (such as earth covering, wire mesh, fence, wall, etc.).
Vibration fiber supports multi-scene installation, such as wall-mounted, wall-mounted, net-mounted, buried and other common scenes, because of its passive front-end, it is very suitable for inflammable and explosive sites, but also suitable for longer peripheral projects, such as airports.
Animals can cause major damage to a property. Stray animals such as dogs, cattle, goats and pigs not just damage the foliage but also dirty the place with their excretions.To stop stray animals from entering the property the most commonly used fence .All fencing can be divided into two types: physical barriers and psychological barriers.
Physical barriers work to create physical obstructions to block cattle movement, such as by using barb wire fencing, rail fences, board fences, or page wire fences.
1.High-precision tension sensor can detect tiny tension changes.
2.Multiple alarm monitoring: alarms for cable tension, slack, shearing, tampering, power failure, etc.
3.Adaptive temperature changes, capable of automatic tracking.
4.Anti-climbing alarm: the front-end fence detection rod, bearing rod, and steering rod have anti-climbing alarm function.
5.Environmental adaptation: the wire rope can be automatically tightened according to changes in the external environment and climate, and the alert can be adjusted tension value.
6.The front steel cable is not charged, and it is widely used in farms, ranches, schools, oil depots, ammunition depots and other occasions.

Psychological livestock fencing, like electric fences, work because cattle are easily trained to fear getting 'zapped' by an angry little wire, which makes them voluntarily resist pressuring the cattle fence.
The series energy control system includes a high-voltage pulse generator and a front-end conductive cable. The high-voltage pulse generator periodically generates a high-voltage pulse with a duration of 100us (about 1/10,000s) When an animal approaches and touches the conductive cable at the front end, the charged cable will give a strong high-voltage blow to the animal that touches it. Although the pulse lasts for a short time, the 12KV high voltage is enough to touch Its animals give a severe warning. After the animals receive this "severe warning", they will form a conditioned reflex and will no longer easily touch the front live cables. Animals in the area will be surrounded by the front live cables. Activities in the area to achieve the purpose of captive animals.

AIRPORT&PORT SECURITY SYSTEM PERIMETER PROTECTION
The airport perimeter physically separates the public activity area from the airport aircraft activity area, which plays a very important role in protecting aircraft from illegal interference and ensuring operational safety. Since the control length of the airport perimeter ranges from nearly ten kilometers to several tens of kilometers, and is affected by climate, weather, geographical environment, etc., these have brought greater challenges to the effective play of the security and defense functions of the security facilities. Combined with the complex perimeter security requirements of airports, it is very necessary to adopt more advanced, more reliable, and simpler security systems.
As the main component of civil aviation airport perimeter security system solutions, the choice of intrusion alarm system detectors is very important. In order to ensure the complete transmission of radio communication between ground and air, airport perimeter security resists radio signal interference to the front-end detectors of the intrusion alarm system There are strict requirements, combined with the external weather conditions of the airport, the temperature difference between summer and winter in some areas is extremely large, and the core components of the detector are also required to withstand the harsh temperature difference. In addition, the perimeter of the airport ranges from more than ten kilometers to dozens of kilometers long, and the detectors must also support long-distance installation. In terms of system stability, the airport has strict regulations on detection probability, false alarm rate, intrusion point positioning accuracy, and convenient installation. In combination with the airport’s perimeter security requirements, vibrating fiber optic intrusion detectors become the first choice
The optical fiber vibration early warning system realizes system early warning for airport personnel climbing, animal intrusion, illegal destruction by illegal personnel, natural disasters, and mechanical construction that may threaten the airport, etc., and combines security personnel to conduct police inspections to conduct intrusion threats to the airport area. Processing to ensure the safe and normal operation of the airport.
Vibrating optical fiber is mainly composed of front-end sensing optical cable, optical fiber host, alarm control server, etc. When an alarm signal is generated, the on-site acousto-optic equipment immediately starts to warn intruders, and the system transmits the alarm signal to the control room for management personnel to access Immediately after the alarm is issued, the police plan is activated.
