摘　　要：为了全面评估旅游安全事故周界安防入侵监测系统的光纤Φ-OTDR传感器性能,本文采用了蝶形单模光纤和侵入板制作了光纤Φ-OTDR传感器,并将该传感器埋在细沙中,利用光纤Φ-OTDR(相位时域反射仪)搭建了基于分布式光纤Φ-OTDR传感器的旅游安全事故周界安防入侵监测系统,并对入侵信息(侵入者位置、重量及高度信息)进行了监测和评估。研究发现,采用所设计的光纤侵入板作为传感器,入侵监测系统能对侵入位置进行准确监测,定位精度小于10 m;重量监测下限达到15 kg;对越高的侵入者监测准确度越高,其准确度可达到99.6%。结果表明:基于光纤Φ-OTDR传感器的入侵监测系统能对长距离、大范围的入侵者进行准确监测,该入侵监测系统可广泛用于旅游景点危险禁区安全事故的安防实时监控。In order to comprehensively evaluate the performance characteristics of fiber-opticΦ-OTDR sensor for travel safety incidents perimeter security monitoring system,the fiber-opticΦ-OTDR sensor,which is fabricated by butterfly single-mode fiber and intrusion plate,is buried in sand firstly.Then this fiber-basedΦ-OTDR perimeter security monitoring system detects and assesses the intrusion information,which included intrusion location,weight,and altitude of intruder.This study found that the detection system can accurately detect intrusion position when a fiberoptic embedded intrusion plate is used as the sensor.The positioning accuracy is less than 10 m,the lower limit of weight detection reaches 15 kg.For the higher intruder,the accuracy is higher and the highest precision reaches 99.6%.The results show that the fiber-basedΦ-OTDR perimeter security monitoring system can accurately detect intruders in a long-distance and large range,and can be used for real-time monitoring for travel safety incidents.
