Fence perimeter security protection system-based integrated wiring method and intrusion early warning method

Abstract

The invention relates to a fence perimeter security protection system-based integrated wiring method and an intrusion early warning method. A fence perimeter security protection system includes an optical fiber alarm subsystem and an upper platform subsystem; the optical fiber alarm subsystem is in connection communication with a remote client through the Internet; the optical fiber alarm subsystem is connected with one detection optical cable; the detection optical cable can be laid on the perimeter of a fence in a surface-laid manner, a wall-embedded manner and a ground-buried manner; the detection optical cable laid through the above three manners is the same detection optical cable; and different portions of the detection optical cable adopt different laying manners. The detection optical cable adopted in the method of the invention can sense the intrusion behaviors of people coming from the outside of the perimeter of the fence in real time; when an intrusion event causes local disturbance, once the detection optical cable receives disturbance signals, the alarm system is notified after the intrusion event is determined as a real intrusion event through comprehensive judgment, and therefore, a misjudgment rate can be decreased, and the sensitivity and accuracy of early warning can be improved.

Description

technical field [0001] The invention relates to optical fiber sensing, in particular to an integrated wiring method for perimeter security systems based on distributed optical fiber vibration sensing technology and an intrusion early warning method based thereon. Background technique [0002] Optical fiber sensing technology developed rapidly with the development of optical fiber communication technology in the 1970s. It is a sensing technology that uses light waves as the carrier and optical fiber as the medium to perceive and transmit external measured signals. These fiber optic sensors can be divided into three categories according to the scope of action: point sensors (such as fiber optic microbending sensors, fiber optic Fabry-Perot sensors, fiber optic Bragg grating sensors, etc.), integral sensors (such as fiber optic Michelson interferometers and fiber optic Mach-Zehnder interferometers) instrument), distributed sensors (such as distributed sensing based on Rayleigh ...

AI Technical Summary

Problems solved by technology

[0003] Traditional security systems based on distributed optical fiber detection generally use detection optical cables to be laid in a straight line or a curve around the perimeter of the wall. Due to irresistible environmental factors such as wind, rain, and strong winds, false alarms often occur, resulting in The alarm accuracy of the optical fiber alarm system decreases
