Title: OPTICAL FIBER PERIMETER INTRUSION SIGNAL IDENTIFICATION METHOD AND DEVICE, AND PERIMETER INTRUSION ALARM SYSTEM
Abstract:
An optical fiber perimeter intrusion signal identification method (10), identification device (30) and optical fiber perimeter intrusion alarm system (40). The identification method (10) comprises: acquiring a real-time signal from a monitoring signal of an optical fiber perimeter monitoring system; pre-processing the real-time signal to remove noises; determining whether the denoised real-time signal is an intrusion signal; if so, truncating the intrusion signal to acquire signal segments of the intrusion signal, and extracting relevant characteristic variables of respective signal segments; and classifying the intrusion signal according to a classification rule determined by a pre-established decision tree model and the relevant characteristic variables of the signal segments. The method is simple, easy to implement, and has a high capability and good effect of intrusion signal classification.
