Host de monitoramento de alarme de perímetro de fibra óptica de vibração distribuída, princípio de composição, fornecedor, fabricante-INNO

Fibra óptica vibratória In the project process of the security industry, perimeter alarm equipment is an important part, and vibration fiber optic perimeter alarm products are the best configuration to replace traditional electronic fences and infrared camera monitoring. But many people don’t know what a vibration fiber optic host is. Abaixo, FJINNO will tell you what a vibration fiber optic alarm system is.

Introdução a Vibration Fiber Optics

Vibration optical fibers, vibration optical cables, and vibration optical cables are commonly referred to as vibration optical fibers. The main installation plan is to lay and wrap around the surrounding fence or wall of the tested object. The main security installation method is to choose the installation method of light vibration according to the customer’s needs and the type of perimeter, such as hanging mesh, buckle mesh, buried and other different installation methods. Divide the scope of this vibration monitoring into different defense zones, and then transmit the alarm information back to the system industrial computer through optical fibers. Then locate the location of the abnormal vibration alarm on the GIS map.

Vibration fiber optic is divided into two equipment deployment modes;

1. Distributed vibration fiber dual zone host

The defense zone host is divided into single defense zone and double defense zone, consisting of one or more vibration fiber optic alarm systems. In the control center, o host de alarme é adicionado com módulos a cada host para receber sinais e implantar defesas.

2. Um host de fibra óptica de vibração de cabo

A zona de defesa é composta por um único ou vários relés de zona de defesa, e o equipamento front-end é instalado passivamente. In the control center, existe um dispositivo de controle de alarme usado para ajustar os parâmetros da zona de defesa, exibindo informações de alarme, implantar e desarmar, e pode ser conectado a um computador para gerenciamento usando software de alarme. O mais recente software de análise de formas de onda desenvolvido por Shanghai e Shi pode distinguir alarmes gerados por diferentes situações, como vento, chuva, pequenos animais, e batendo. Analisando as características das mudanças na forma de onda, o software pode distinguir a verdadeira situação do evento e filtrar alarmes desnecessários, minimizando a taxa de falsos alarmes.

What is the composition of a vibrating fiber optic host

The optical cable vibration sensing alarm system consists of five main parts: monitor, main controller, sensor, sensing optical cable, and external components. Entre eles, the system monitor and main controller are located in the monitoring room, and the guiding optical cable, sensing optical cable, and external components are installed outdoors.

The working principle of vibrating optical fibers:
When fiber optic sensors are affected by external interference, some of the characteristics of the transmitted light in the fiber optic will change. By configuring special sensing equipment and collecting and analyzing signals, changes in the characteristics of the light (ou seja. attenuation, fase, comprimento de onda, polarização, mode field distribution, and propagation time) can be detected. The characteristic changes of light are distinguished from normal interference by the special algorithms and analysis processing of the alarm controller, achieving alarm and positioning functions.

Composition of vibration fiber optic signal acquisition host

Mainly based on the principle of “fiber optic interferometer”. In order to detect weak vibrations, a balanced fiber optic interferometer is constructed using two core single-mode fibers. When a coherent laser is emitted from it, the interferometer composed of these two fibers outputs an interference light signal. When the fiber optic is disturbed by external factors such as excavation, touch, and tapping, the output waveform of the interference light changes and generates an interference image. This waveform change can be detected by a light detector. By analyzing the characteristics of the changed waveform through software, the true situation of the event can be distinguished, thus achieving the effect of “intrusion pattern recognition”.
