1前言基于光纤光栅振动传感技术的智能化周界防范新系统,将由光纤光栅振动传感器构成的振动探测光缆作为核心设施的第一道防线,在设施的最外层对入侵行为进行探测,便于安保人员进行及时的干预,阻止严重损失行为的发生。该系统能够准确识别各类入侵行为,抑制风雨等气象因素对系统性能的影响,既保证了光纤光栅传感器的高灵敏特征,也极大地降低了系统的误报率指
1 INTRODUCTION Intelligent perimeter defense system based on FBG vibration sensing technology uses the vibration detection optical fiber cable consisting of FBG vibration sensor as the first line of defense of the core facility to detect intrusion at the outermost layer of the facility so as to facilitate Security personnel to make timely intervention to stop the serious loss of behavior. The system can accurately identify all kinds of intrusion behaviors and restrain the influence of meteorological factors such as wind and rain on the system performance, which not only ensures the highly sensitive characteristics of the fiber grating sensor but also greatly reduces the false positive rate of the system
