Method for setting linkage type positioning optical-fibre boundary security system

Abstract

The invention discloses a method for setting a linkage type positioning optical-fibre boundary security system, and belongs to the technical field of security engineering. The method is characterizedby comprising the steps of: a, selecting an alarm detector; b, increasing the setting distance for a defence area, where persons frequently go in and out, and decreasing the setting distance for a safety protection blind area, where few persons go in and out; c, in combination with environmental requirements, selecting an alarm detector suitable for an environment; d, confirming boundary defence area division according to the selected alarm detector; e, adjusting the sensitivity of the alarm detector; f, determining the installation position of a boundary camera; and g, communicating an alarmsignal in the defence area to an intermediate system, sending a pre-set command of steering and focusing the called boundary camera through the intermediate system, and completing boundary security and video monitoring linkage. According to the method in the invention, due to the linkage mode, the disadvantage that single vision monitoring has a blind area can be avoided; the dynamic response of an alarm is effectively improved; and integrated application is improved.

Description

technical field [0001] The invention relates to the technical field of security engineering, in particular to a setting method of a linked positioning type optical fiber perimeter protection system. Background technique [0002] Most of the perimeter defense systems realize the detection of illegal intrusion by setting intrusion detection and alarm equipment on the steel mesh fence and brick wall fence. Generally, it can be divided into contact perimeter alarm system and non-contact perimeter alarm system, but no matter what type of technology the system is, the alarm detection equipment is segmented, partitioned and corresponding to the specific location, so that it can be detected in time when illegal intrusion occurs. Get location information. When an alarm signal is triggered, the perimeter cameras near the perimeter will turn to the alarm area according to the preset position, forming the linkage closed management of alarm detection and video surveillance system.

AI Technical Summary

Problems solved by technology

[0003] 1. If the alarm area is divided too finely, the number of detectors, controlled equipment, such as perimeter cameras will inevitably increase, which is uneconomical

[0004] 2. The division of the alarm area is too large, and the location information cannot be truly reflected after the actual alarm, which is not conducive to the handling of the alarm event, and the handling personnel cannot be in place in time

[0005] 3. By adding fixed video surveillance equipment at the perimeter as a supplement to perimeter defense and as a basis for evidence collection after illegal intrusion, there may be dead spots in surveillance

[0006] 4. Although there is linkage between the perimeter defense system and the video surveillance system, due to the high accuracy error or false alarm rate of the perimeter system itself, the linkage is not in place or the linkage is frequent after the early warning, and the system availability is poor

[0008] The defense zone arming and positioning method of the perimeter defense system disclosed in this patent document adopts multi-defense zone compounding, which can prevent the failure of the defense zone equipment from causing the entire security system to fail, and ensure the reliability of the system. However, the dynamic response and integrated application of the alarm are poor. high investment cost
