摘要
A novel armored-cable-based FBG security fence for perimeter intrusion detection with higher performance is proposed and demonstrated. The sensor is based on a unique armored-cable packaged FBG sensor array, which guarantees high sensitivity, crush resistance, and protection against rodents. It provides fine granularity perimeter intrusion detection, with a stated pin-pointing accuracy, for the tested intrusion events that include aided or unaided climbs, tampering and cutting of the fence. It is also capable of resolving nuisance events such as rain, birds sitting on the fence and seismic vibrations caused by the vehicular traffic, landing or taking off of aircrafts, etc. Moreover, it is temperature independent since the ambient temperature variation can be regarded as a direct-current (DC) signal, and has no effect on the alternating current (AC) signal of the vibration signal induced by the intruder. It is potential to be used in various scenarios where a very small physical parameter change could cause some vibration.
