Abstract

The invention relates to the technical field of sensing detection, in particular to a large-scale long-distance perimeter security system based on fiber bragg grating vibration sensing and a using method thereof. The large-scale long-distance perimeter security system comprises a fiber bragg grating vibration sensing array, a fiber bragg grating wavelength demodulation system and a signal processing and control system, wherein the fiber bragg grating vibration sensing array comprises a 16-core single-mode optical cable with the length of 25 kilometers and a fiber bragg grating vibration sensor; the fiber bragg grating wavelength demodulation system comprises a broadband light source for emitting broadband light; the signal processing and control system comprises a signal processing and fusion module, a main controller module and an alarm information module. The beneficial effects of the large-scale long-distance perimeter security system based on fiber bragg grating vibration sensing and the using method thereof are that the problem is solved that an optical fiber sensor of a border security early-warning system is short in sensing distance and cannot achieve the large-scale hiddenarrangement, and the long-distance and large-range early-warning of a border is achieved.

Description

technical field [0001] The invention relates to the technical field of sensing and detection, in particular to a large-scale long-distance perimeter security system based on fiber grating vibration sensing and its application method. Background technique [0002] Traditional security monitoring technology is mainly based on electrical sensors, which cannot meet people's requirements for security monitoring due to reasons such as power supply and susceptibility to electromagnetic interference. Optical fiber intrusion monitoring system has the advantages of anti-electromagnetic interference, good electrical insulation, corrosion resistance, and large-scale monitoring. It has good concealment and can be used to monitor and protect borders, military bases, power plants, nuclear design, prisons, and airports. , oil pipelines and other important facilities. With the needs of the market and the efforts of domestic and foreign researchers on optical fiber security monitoring techno...
