Optical fiber distributed disturbance and video linkage long-distance circumference security monitoring system

Abstract

The invention is applied to a circumference security system, relates to a technology for positioning an invasion position and monitoring the invasion position in real time, and aims to provide a device for monitoring and recording the invasion position in real time. According to the technical scheme, an optical fiber distributed disturbance and video linkage long-distance circumference security monitoring system comprises a sensing optical cable 2 paved at the circumference of a security protection region, wherein the sensing optical cable is connected with a disturbance pre-warning and positioning system 3; the disturbance pre-warning and positioning system 3 comprises a sensing module 4, a light source module 5, a detector module 6 and a light source module 7; the sensing module 4 comprises a sensing light path unit and a polarization control unit; a disturbance warning server 8 transmits information such as an invasion warning, an invasion mode and the invasion position to clients through a router 9; and a video hard disk tape recorder is used for automatically recording videos in real time. The optical fiber distributed disturbance and video linkage long-distance circumference security monitoring system is mainly applied to design and manufacturing for security monitoring systems.

Description

technical field [0001] The invention is applied to a perimeter security system, and relates to location and real-time monitoring of intrusion positions, specifically, to a long-distance perimeter security monitoring system linked by optical fiber distributed disturbance and video linkage. Background technique [0002] At present, the traditional perimeter security system mainly includes access and exit, installation of physical fences, personnel inspections, and video surveillance. Common video surveillance systems need to manually control the monitoring range, or set a fixed cruising route for cruising, which depends on the monitoring area and In the case of a large distance, it is difficult to monitor and record the intrusion location in real time, and there are monitoring loopholes.

AI Technical Summary

Problems solved by technology

[0002] At present, the traditional perimeter security system mainly includes access and exit, installation of physical fences, personnel inspections, and video surveillance. Common video surveillance systems need to manually control the monitoring range, or set a fixed cruising route for cruising, which depends on the monitoring area and In the case of a large distance, it is difficult to monitor and record the intrusion location in real time, and there are monitoring loopholes

[0003] At present, at home and abroad, there are still some distributed intrusion monitoring systems based on electromagnetic principles, such as intelligent electronic pulse fence system, tension electronic fence, and vibrating cable alarm system. These three intrusion alarm systems are new technologies in the field of security, but the cost is common. High, cumbersome construction, high maintenance cost and difficulty when used in large areas

[0004] These new distributed intrusion monitoring systems all have a common fatal flaw. They cannot accurately locate the location of the intrusion while monitoring, and monitor and record the location of the intrusion in real time.

In the case of a large monitoring area and distance, issuing an alarm can only block a small amount of erroneous intrusions, which obviously cannot meet the high-level security requirements of those large, special and sensitive monitoring objects.
