The optical fiber fence sensing early warning system based on optical fiber sensing technology has attracted more and more attention. Compared with the traditional fence alarm system, the fiber optic fence warning system has the advantages of high sensitivity, resistance to electromagnetic interference, corrosion resistance, passive whole process, wide monitoring range, etc. Optical fiber is used as sensing medium for remote and real-time monitoring of unexpected events in a certain range. At present, the monitoring technology based on optical fiber sensors has been applied in many fields, such as oil and gas pipeline monitoring, health inspection of large structures such as bridges, buildings and so on. Fiber optic fence sensing early warning system not only has a broad application prospect in perimeter security field, but also is the mainstream research direction of intelligent security in the future. Therefore, the research of fiber-optic fence sensor early-warning system has important practical significance. In this paper, by comparing several commonly used detection techniques in the fiber fencing system, a new type of fiber-optic fence sensing and warning system is designed and implemented by using M-Z interferometry, and the feasibility of the system structure is analyzed. Finally, the experimental results show that the fiber optic fence sensing early warning system based on M-Z interferometry can effectively realize the early warning of intrusion behavior. The main work of this thesis is as follows: (1) the domestic and foreign research status of the optical fiber fencing sensor early warning system is analyzed.
