摘　　要：地埋式入侵监测系统具有隐蔽性强、受自然因素影响小、误报率低、识别概率高等特点,在入侵监测中具有重要作用。介绍了将光纤传感用于入侵监测的主要技术方案,阐述了光纤分布式振动传感(DVS)系统和光纤布拉格光栅(FBG)振动传感系统的工作原理。对这两种系统进行了人员入侵监测实验。结果表明,DVS系统的有效探测范围可达到10~15m,空间分辨率约为20m;FBG振动传感系统的最大有效探测距离超过75m。对比和评估了这两种系统的关键性能,展望了地埋式光纤入侵监测系统的应用方向。A buried intrusion monitoring system has the characteristics of strong concealment, little affected by natural factors, low false alarm rate and high identify probability, and plays an important role in intrusion monitoring. The main technical scheme for security intrusion monitoring based on fiber sensing is introduced. The working principles of the fiber distributed vibration sensing （DVS） system and the fiber Bragg grating （FBG） vibration sensing system are described. Personnel invasion monitoring experiments for the two systems are carried out. The results demonstrate that the maximum effective detection range of the DVS system is 10-15 m, and the spatial resolution is about 20 m. The maximum effective detection distance of the FBG vibration sensing system is beyond 75 m. The key performances of the two systems are compared and evaluated, and the application of buried fiber intrusion monitoring system is also discussed.
