This paper constructs a distributed optical fiber sensing technology perimeter security monitoring system based on dual Mach Zehnder interferometer and an intelligent video linkage system based on Four-rotor UAV with video tracking function.The system integrates distributed optical fiber disturbance sensing technology with UAV technology.Distributed optical fiber sensing technology is based on two-way Mach Zehnder interferometer,and Positioning using time delay difference between positive and negative signals.UAV carries out video processing for Four-rotor UAV with ODROID airborne computer.The disturbance sensor system monitors all kinds of intrusion behavior,locates the intrusion by signal processing,and sends out alarm information.At the same time,UAV Video Linkage.UAV uses its"God′s Perspective"to explore the intrusion location,monitor the intrusion,and track the intruders in real time.Video intrusion is recorded and transmitted to the terminal.The whole process is intelligent and automated.The experimental results show that the positioning accuracy of the system can reach 10 m,the Four-rotor UAV has the advantages of stable flight,fast response,automatic recording,automatic return,and real-time transmission of video to the client.The test results show that the system can effectively detect and locate intrusions,and realize video linkage with UAV.The system integrates distributed optical fiber sensing technology and intelligent UAV video link technology to form a hybrid intelligent perimeter security monitoring system.
