摘要： A distributed optical fiber perimeter security system, and sound restoration system and method. The sound restoration system is applied to the distributed optical fiber perimeter security system monitoring several protection areas. The sound restoration system comprises: a laser generation mechanism (11) for providing a laser signal; a beam splitting mechanism (12) for splitting the laser signal into multiple input optical signals; a plurality of optical fiber Michelson interferometer mechanisms (13) corresponding to each of the protection areas, wherein each of the optical fiber Michelson interferometer mechanisms (13) receives an input optical signal and outputs, in response to a surrounding sound pressure, an interference signal; and an audio output mechanism (14) for receiving the interference signal and when an alarm signal of any of the protection areas is received, outputting an audio signal restored according to the interference signal of the protection area. The system can help a user make a further confirmation and determination on an occurrence of abnormal events such as intrusions.

摘要： 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.
