Intelligent optical fiber vibration anti-intrusion early warning method and system

Abstract

The invention relates to an intelligent optical fiber vibration anti-intrusion early warning method and system. The method comprises the steps of (S1) performing photoelectric conversion on an opticalsignal returned by a sensor, (S2) performing pattern matching on a converted digital signal, (S3) performing data processing according to the selected mode and checking whether an intrusion conditionis satisfied, and (S4) performing linkage alarm if the intrusion condition is satisfied. According to the invention, the optical fiber vibration anti-intrusion early warning is achieved, when external disturbance exists, the early warning can be effectively performed, the degree of automation is high, and the false alarm rate is low. When the intrusion condition is satisfied, the linkage alarm isperformed, the multiple modes of simultaneous alarms are achieved by TCP alarm message push, UDP alarm message push and short message push, the shortcomings of the single alarm mode are compensated,the omission of staff information reception is prevented in alarm, therefore, the reliability of system work is effectively ensured, and the probability of failures is reduced.

Description

technical field [0001] The invention relates to the technical field of perimeter protection, in particular to an intelligent optical fiber vibration anti-intrusion early warning method and system. Background technique [0002] With the continuous exploration and development of optical fiber technology in the past ten years, the optical fiber detection and alarm system using optical fiber sensing as a detection method has gradually matured and stabilized. Compared with traditional alarm detection technology, it has anti-electromagnetic wave interference, wide application range, high sensitivity, It has many advantages such as high concealment and strong anti-interference, and has been applied to the security system of airports, important warehouses, prisons, finance and other fields, as well as high-end buildings. [0003] Traditional security technologies mainly include infrared radiation, laser detection, electrostatic induction, etc. All of these technologies have the disa...
