Gentian optik getaran untuk sistem penderiaan dan pemantauan keselamatan perimeter, kaedah pemasangan dan meletakkan-INNO

The fiber optic vibration sensing perimeter security system can effectively detect illegal intrusion, suitable for any environmental, climatic, and geomorphic characteristics, and can reliably respond to various emergencies. Once an alarm occurs, the system can perform feature analysis on the intrusion signal, use environmental intelligent mode analysis to filter and shield false alarm signals, and transmit the alarm signal to the control center in the first time. It also links with cameras, penyiaran, lighting and other equipment on site to monitor and process the situation from multiple locations, thus establishing a comprehensive security guarantee system. The system is widely used in typical perimeter scenarios such as communities, penjara, lapangan terbang, and railways. The response time of the video linked fiber optic vibration sensing perimeter security system is less than 15ms, with an accuracy rate of over 92% and a false alarm rate of less than 2%. It can achieve the goal of quickly and accurately judging and protecting against external intrusion and disturbance.

Traditional perimeter defense is no longer suitable for the security needs of critical departments, and installing advanced security technology prevention systems has become an inevitable measure. The perimeter alarm system is an important component of the security technology prevention system and the first line of defense for the security alarm system. In some important areas, such as communities, penjara, lapangan terbang, kereta api, dll., perimeter security systems can be built to prevent illegal intrusion and various destructive activities, memastikan keselamatan nyawa dan harta benda rakyat. Sistem keselamatan perimeter tradisional yang menggunakan teknologi seperti sinaran inframerah, sinaran laser, pagar elektronik denyut, pagar elektronik ketegangan, dan kabel bocor mempunyai kos yang tinggi, antara empat hingga lima ratus ribu yuan hingga berjuta-juta yuan. Namun begitu, penggunaan gentian optik pengesan getaran yang dikaitkan dengan pemantauan video boleh mencapai keselamatan yang lebih tinggi dan memenuhi keperluan pelbagai senario aplikasi pada harga yang lebih rendah.

Kaedah pemasangan dan peletakan gentian optik teragih sistem penderiaan dan pemantauan keselamatan perimeter:

1. Cegah akses yang tidak dibenarkan

jaringan dawai

Peletakan linear: Kabel optik penderiaan tunggal dipasang dalam garis lurus mendatar pada grid kereta api, yang boleh mengesan kaedah pencerobohan seperti memanjat dan melintas, dan sesuai untuk majlis dengan keperluan keselamatan yang rendah.

Peletakan garis selari: Kabel optik penderiaan berbilang dipasang secara mendatar pada grid besi untuk meningkatkan kawasan pengesanan dan penderiaan, meningkatkan sensitiviti pengesanan isyarat pencerobohan, dan mengesan kaedah pencerobohan seperti memanjat, memanjat, dan memotong jaring. Ia sesuai untuk majlis dengan keperluan keselamatan yang tinggi.

Pagar logam

Disebabkan tekstur pagar logam yang keras, untuk mengurangkan penggera palsu, adalah perlu untuk menambah bilangan kabel optik sensor yang diletakkan untuk memastikan kepekaan pengesanan, seperti meletakkan satu kabel optik sensor di bahagian atas, tengah, dan bahagian bawah pagar. Apabila keperluan keselamatan tinggi, perimeter boleh ditambah

Bilangan kabel optik penderiaan diletakkan di tengah-tengah lajur.

Rangkaian besi bulat

The circular iron network is usually located at the top of the fence and has a lightweight and scattered structure, which is susceptible to environmental disturbances and false alarms. Oleh itu, sensing optical cables should be laid on both sides of the fence near the bottom of the iron network. Due to the inability of this laying method to prevent wall excavation intrusion

It is best to use it in conjunction with other laying methods.

2. Prevent wall intrusion by chiseling

Lay multiple sensing optical cables in parallel on the wall to detect the vibration alarm generated during wall chiseling. To reduce false negatives, the number of sensing optical cables should be increased according to the height of the fence, and the optical cables should be fixed at equal intervals on the wall.

3. Underground anti crossing intrusion

The buried laying of sensing optical cables is relatively concealed and not easily detected by intruders in advance. Determine the laying depth based on the ground conditions (such as grassland, sand, dll.), lay the sensing optical cable in an S-shaped or parallel manner with multiple sensing optical cables, and then re cover it. When an intruder enters the defense zone or the vibration generated by underground excavation is detected, an alarm will be triggered. The embedded fiber optic grating perimeter system can detect various vibrations around it, and through linked video surveillance, it can distinguish various intrusion behaviors. Contohnya, when someone passes within 3 meters of the vibrating optical cable, sistem boleh mengesan isyarat yang tidak normal dan mendapatkan maklumat pemantauan lokasi pencerobohan untuk menentukan sama ada ia adalah tingkah laku pencerobohan.
