摘　　要：针对轨道交通车辆段停车场的周界安全问题,提出利用地埋式光纤测振周界入侵报警系统,连续实时地监测轨道交通车辆段停车场周边出现的异常振动信号,同时融合视频识别信息对周界环境进行预判,给出最优的报警策略参数,对入侵行为进行识别和定位,既保证光纤周界系统的高灵敏度特性,同时有效降低系统的误报率。文中介绍了地埋式光纤测振周界入侵报警系统的安装实施方式和信号处理方法。经过模拟测试统计和长期运行观察,地埋式光纤测振周界入侵报警系统结合视频信息融合算法,可对车碾压、人行走等多种入侵行为进行有效报警和准确定位,系统报警正确率可达到98%~99%,误报频次≤3次/月。Aiming at the perimeter security problem of rail transit vehicle depot parking lot,an embedded optical fiber vibration detection perimeter intrusion alarm system is proposed to continuously and real-time monitor abnormal vibration signals around rail transit vehicle depot parking lot.Meanwhile,video recognition information is integrated to predict the perimeter environment,and optimal alarm strategy parameters are given to identify and locate the intrusion behavior.It not only ensures the high sensitivity of the fiber perimeter system,but also reduces the false alarm rate effectively.The installation,implementation and signal processing method of the embedded fiber optic vibration detection perimeter intrusion alarm system are introduced.After simulation test statistics and long-term operation observation,the buried fiber optic vibration detection perimeter intrusion alarm system combined with video information fusion algorithm can effectively alarm and accurately locate a variety of intrusion behaviors such as vehicle rolling and human walking.The alarm accuracy rate of the system can reach 98%to 99%,and the false alarm frequency is less than 3 times per month.
