Some time ago, a customer in a certain place consulted our market personnel. There is a substation project, which needs to use perimeter protection products, and requires a long transmission distance, anti-interference performance is good, to ensure no interference to the substation. In response to this request, our market personnel recommended the vibrating fiber optic system for the customer, which just met the needs of all aspects of the project. Finally, the customer selected the Ai Li'an vibrating fiber system through research and investigation.
As a special alarm system in perimeter prevention, what is the working principle of vibrating fiber? What are the unique advantages? This article takes you deeper into the Ariane Vibrating Fiber System!
First, the working principle of vibrating fiber
The vibrating fiber belongs to the high-end alarm system in the perimeter alarm system. It is different from the infrared beam-blocking beam warning. It is also different from the touch alloy wire of the pulse electronic fence. The working principle is that the laser emits DC monochromatic light and light. The signal passes through the optical module to generate two interference signals through the optical module. The signal uses the optical fiber as the vibration sensing carrier to realize the protection early warning detection. When someone illegally invades, the intensity of the light wave signal is higher than a predetermined index, thereby generating an alarm signal.
Second, the vibration fiber system composition
Ai Li'an vibrating fiber is mainly composed of zone collector, terminal box, zone division package, fiber patch cable, etc. According to different projects, different zone collectors are used. Zone collectors can be divided into double zones, four zones, and eight zones. Wait.

Four-zone vibration fiber system
Eight-zone vibration fiber system
Three, four alarm methods
After talking about its working principle and system composition, let us look at the alarm mode of vibrating fiber in the actual operation process, which can be divided into the following categories:
Intrusion alarm: direct or indirect vibration
Wire break alarm: Inductive cable disconnection
Unpacking the alarm: illegally dismantling or destroying
Communication failure: communication cable disconnection
Four, three installation methods
Different from the electronic fence and infrared radiation mounted on the fence or fence, there are some special ways to install the vibrating fiber, mainly including three methods: underground, hanging net and buried wall.

Five, Ai Li'an vibration fiber advantage
As a set of perimeter alarm system, Ai Lian vibration fiber has the advantages of long transmission distance, strong anti-interference performance and passive design, which can meet the application requirements of various perimeter types.
Long distance
Each zone (fiber length) is up to 1 km long, and the overall prevention of large-scale and long-distance is realized in the true sense.
Passive design
The system uses optical fiber as a passive detector, except that the host needs to supply power, and the entire outdoor zone is passive.
Anti-interference
The system uses fiber optic detection, which does not need to consider the influence of electromagnetic fields, and has excellent anti-interference ability. It is very suitable for oil storage, power station, military, airport, high-speed rail and other occasions.
Adaptive
Running continuously for 8 hours, the adaptive ability of the device will achieve the desired result.
Sixth, Ai Li'an vibration fiber design
Vibration fiber distribution alarm management system
Vibration fiber network alarm management system
Vibration fiber optic bus alarm management system
to sum up
Ai Li'an vibrating fiber transmission distance is long, the outdoor outdoor zone has passive design and excellent anti-interference performance, and it has a special vibration fiber optic software platform to manage and control it, which can be used for real estate, electric power, military, airport, petrochemical, national defense, The perimeter, prevention, and security are provided in many areas such as the judiciary, the government, and the civil society.
