Fiber optic has the advantages of good light transmission characteristics, 電磁干渉防止, and good electrical insulation. Distributed fiber optic sensing system is a sensing system that uses fiber optic as a sensitive element and signal transmission medium. It can reveal the changes in temperature, stress, and vibration information at any position within the range of fiber optic laying through the scattering effect of light.

Through distributed fiber optic sensing テクノロジー, it is possible to detect distributed information over a large area and widely apply it in various fields of social life. 例えば, distributed stress sensors can be used in the safety inspection of large public facilities such as bridges, トンネル, and dams, or in the aging degree detection of aircraft, aerospace equipment, 等; Distributed vibration sensors can be used in anti intrusion alarm systems in important areas such as airports, prisons, military bases, or in anti leakage monitoring systems for oil and gas pipelines; Distributed temperature sensors can be used for temperature measurement of large transformers and generator sets, as well as in fire protection and intrusion prevention alarm systems for large warehouses, oil depots, mines, and tunnels.

Distributed fiber optic vibration sensing system is a distributed sensing system that uses fiber optic as the transmission medium to implement remote real-time monitoring of vibration events within the range of the fiber optic laid line. Featuring resistance to electromagnetic interference, 腐食, 高感度, and high positioning accuracy, it is suitable for intrusion prevention alarm systems in important areas, as well as leak prevention monitoring systems in oil and gas pipelines.

Fiber optic vibration sensing technology is a relatively active research and development technology in the field of fiber optic sensing, applied to many fields such as perimeter safety protection, urban pipeline corridors, and pipeline warning. Distributed fiber optic sensing is a technology that uses fiber optic as the sensing medium to remotely and in real-time monitor objects along the fiber optic line. It is widely used in long-distance safety monitoring such as natural gas transmission pipelines, oil pipeline monitoring, and health monitoring of civil facilities such as bridges and large buildings.

Distributed fiber optic sensing system is a sensing system that uses fiber optic as the sensing medium, which can remotely and in real-time monitor the safety of objects along the fiber optic line. It has many advantages, including:
1. Integrating sensing and transmission, capable of remote measurement and monitoring;
2. A one-dimensional distribution map along the entire fiber optic cable can be obtained through only one measurement;
3. Only one system can obtain a large amount of relatively continuous data information on a sensing fiber optic loop that is several kilometers or even tens of kilometers long.

そこで, a distributed fiber optic sensing system can simultaneously obtain the distribution information of the measured field along the fiber optic path in both time and space, enabling large-scale parameter monitoring.

目下, monitoring based on distributed fiber optic sensing technology has been applied in many fields, including long-distance monitoring of oil and gas pipelines and fiber optic cable monitoring for safety monitoring; There are also health monitoring of civil facilities such as bridges, large buildings, and other civil structures; There is also security monitoring in sensitive areas such as airports, nuclear power plants, 工場, and military bases. そこで, the research on distributed fiber optic sensing systems has positive significance for safety monitoring, 生産, そして日常生活.
