Abstract: Optical fiber sensing technology has the advantages of anti-electromagnetic interference, no power supply on site, simple maintenance and high sensitivity, which is very suitable for the application of perimeter security monitoring in important places. This paper takes the optical fiber early warning system implemented in the perimeter of an oil transmission station as an application case, aiming at the problem that the high sensitivity and low false alarm rate of the optical fiber security system cannot be taken into account at the same time, and discusses system layout and signal analysis and other aspects. Through testing experiment and operation observation, the method adopted in this paper can effectively suppress the false alarm caused by wind and rain weather, and effectively improve the monitoring effect of optical fiber early warning system.
Keywords: perimeter security; vibration detection; optical fiber sensing
