Security and monitoring systems not only play an important role in people’s daily lives, but also have obvious advantages in the application of protection in key areas such as banks, prisons, and border lines. The traditional reliance on manual inspection not only wastes a lot of manpower and material resources, but also has a small per capita monitoring range, making it difficult to achieve real-time monitoring. Infrared and laser targeting schemes are easily affected by natural climates such as high and low temperatures, rain, snow, and fog, and are also prone to being crossed or avoided. The sensing part of leakage cables or vibration cables is active, and the system power consumption is high. When the monitored range is large, the cost and maintenance cost of such systems themselves are high. A single video surveillance system also has many drawbacks, lacking a linkage mechanism, which can lead to missed detections. The intelligent fiber optic security system has a simple structure, is resistant to electromagnetic interference, corrosion, and has good insulation performance. It can be applied in special environments such as flammable and explosive, forte interferenza elettromagnetica, and harsh weather, and has broad application prospects and a wide range of applications.

Aiming at the limitations of current fiber optic perimeter detection systems, an intelligent fiber optic perimeter intrusion alarm system is proposed. The system not only includes fiber optic perimeter intrusion detection, but also integrates functions such as video monitoring and high-frequency alarm. It can achieve both local monitoring and remote B/ S-mode access, forming a larger area of information exchange, and achieving a larger range of monitoring. The system not only saves a lot of manpower and resources, but also facilitates later maintenance, making it easy to upgrade and expand the system.

Intelligent Fiber Optic Perimeter Intrusion Alarm System

Including detection optical cables, fiber optic perimeter intrusion detectors, linkage modules, network hard disk recorders, industrial switches, network ball machines, sound and light alarms, tweeters, and upper computers;
Detect the vibration signal sensed by the optical cable and provide the vibration signal to the fiber optic perimeter intrusion detector. The fiber optic perimeter intrusion detector filters out environmental interference signals, and then analyzes the target characteristics of the vibration signal to determine whether it is an intrusion signal. After identifying whether it is an intrusion behavior, based on the location of the intrusion behavior, the industrial switch sends the region location information command to the network hard disk recorder. The network hard disk recorder analyzes the information and controls the network ball machine responsible for monitoring the area through the industrial switch to switch to the intrusion location for taking photos and certificates;
In listessu tempu, the fiber optic perimeter intrusion detector controls the sound and light alarm through the linkage module to provide alarm reminders and the local high pitched horn to shout and drive away; The upper computer located in the remote monitoring center realizes the remote release and monitoring of alarm information and recording information, as well as accessing video data stored in the network hard disk recorder. It also includes fiber optic transceivers for communication connection between industrial switches and network ball machines. The linkage module controls the operation of the sound and light alarm and the high pitched horn through a serial port to a relay.

Installation of prison intelligent fiber optic perimeter intrusion alarm system

The upper computer achieves remote publishing and monitoring of alarm information and recording information through B/S access, which refers to the browser/server access method. When the detection optical cable is set on the fence, it is fixed on the fence in a circular hanging manner. When the detection optical cable is installed on the wall, a Y-shaped bracket is installed on the wall, and the hanging wire mesh is fixed on the Y-shaped bracket. The detection optical cable is fixed on the hanging wire mesh in a circular hanging manner. When the detection optical cable is installed underground, a buried steel wire mesh is buried underground, and the detection optical cable is fixed on the buried steel wire mesh in a sine curve manner.

A comprehensive intelligent fiber optic perimeter intrusion alarm system. In terms of setting up the detection optical cable, two methods were adopted: hanging network and buried laying, which are conducive to the perception of intrusion behavior and achieve three-dimensional perimeter security protection;
The fiber optic perimeter intrusion detector has the ability to detect various vibration events throughout the entire fiber optic cable section. It effectively classifies and identifies intrusion behaviors such as personnel and vehicles, and can shield and filter common disturbance signals with high accuracy;
The system comprehensively utilizes video surveillance and evidence collection as well as the high pitched speaker drive off function, making the entire system have better security effects;
The system can achieve both local and remote monitoring simultaneously, facilitating expansion and centralized large-scale monitoring.
