Optical fiber micro-vibration sensor alarm system
----Long-distance, large-scale defense monitoring solution
Optical fiber micro-vibration sensor alarm system is a new generation security system. The system uses fiber optic sensing technology. It can provide up to 100 kilometers security monitoring without the need for any outdoor active devices (without power supply) situation. It is particularly suitable for long-distance, large-scale regional defense.

Intrusion alarmsystem of geographic informationinterface |
The system can provide with real-time and reliable intrusion alarm information instantly and effectively. When intrusion generated by the stampede, touching, shaking, squeezing, etc., which will makes tiny cable vibrations, the system instantly alarm, and locate the alarm position (positioning accuracy of 50 meters) accurately.
Nowadays, only a few companies in the United States have succeeded in applying this technology in the field of border defense, airports, important warehouses and other defense fields. The research achievements of our company in this technology are at the international advanced level.
Optical fiber micro-vibration sensor alarm system: the sensing cable should be disposed near the monitoring perimeter by means of hanging or burying, it is sensitive to the stress changes of the external environment. When invasion occur and cause vibration, the system generates an alarm after signal processing and display the real-time GPS coordinates of intrusion location on the geographic information system software interface.

4、System Architecture
Optical fiber micro-vibration sensor alarm system is divided into two sets of "zone location" and "precise positioning" products.
Zone location: Zone location products are low-end products of fiber optic micro vibration sensing system. Its system structure is shown below:
Areaproduct positioningsystem structure diagram
Two adjacent terminal boxes and sensor cable between them form a zone. When a zone send the alarm information, the system can quickly locate the zone. But it can not determine the exact location of the anti-zone alarm. The length of the Zone can be set according to the users’ need, it can range from a few hundred meters to several kilometers. At present, the maximum number of zones that the system can test is 20.
Precise positioning: precise positioning products are high-end products of fiber micro-vibration sensor system. The system structure is shown below:
Accurate positioningsystem structure diagram
This product lay a sensor cable across the entire defense area. It do not need to add any intermediate devices. When there is an intrusion alarm, the system can quickly locate the invasion site and display in real time on the system software interface, and gives the GPS coordinates of the point of the invasion. The positioning accuracy is 50 meters. |
