基于光纤光栅传感技术的周界入侵报警系统

介绍了一种基于光纤光栅传感技术的周界入侵报警系统,利用不同入侵模式信号时域及频域特征信号的差异性,采用时域与频域与信号结合的分析方法,实现对各种入侵信号的模式识别及报警判断,并通过模拟实验加以验证。实验结果表明,该系统能够实现对入侵行为的模式识别及对有害入侵模式实施报警的功能。

Perimeter Intrusion System Based on Fiber Bragg Grating Sensing Technology

This article introduces a perimeter intrusion system based on Fiber Bragg Grating （FBG） sensor. It could finish the intrusion pattern recognition and distinguish different intrusion by using the Time-frequency analytical method. The classification and feature analysis of Time-frequency signal are carried out to realize the pattern recognition. The results of the intrusion simulating experiments show that the Time-Frequency analytical method resolves the pattern recognition problem, which improves detection rate and reduces false positive rate of the perimeter intrusion system.
