Distributed optical fibers can be applied in different fields, such as power equipment, النقل بالسكك الحديدية, tunnel cables, natural gas and oil pipelines, الخ., and can monitor parameters such as temperature, اهتزاز, strain, pressure, الخ.
Application of Distributed Fiber Optic Temperature Online Monitoring System
The distributed fiber optic temperature measurement system utilizes the principle of fiber optic Raman scattering and OTDR technology to achieve products with fiber optic as the sensing carrier and distributed temperature measurement. Raman temperature measurement technology is currently a relatively mature technology and has been widely applied.
The distributed fiber optic temperature sensing system has advantages such as distributed temperature measurement, السلامة الجوهرية, passive explosion-proof, مكافحة التداخل الكهرومغناطيسي, مقاومة التآكل, عمر خدمة طويل, long measurement distance, and low maintenance cost. It is widely used in fields such as oil tank fire protection, crude oil transmission leakage monitoring, power tunnel temperature measurement, and belt conveyor status temperature monitoring.

Distributed fiber optic strain monitoring
The distributed fiber optic strain monitoring system utilizes the sensitivity of the frequency of backscattered Brillouin light in the fiber optic to external stress and temperature, and has a good linear relationship. By demodulating the backscattered signal of the fiber optic, the strain and temperature information distributed on the fiber optic can be obtained. Fiber optic is both a sensing element and a transmission medium, and it is flexible and bendable. It can be composite in any form in the matrix structure without affecting the performance of the matrix. It is mainly used for monitoring the strain of dams, embankments, bridges, and other concrete structures. In terms of geological hazard monitoring, it can be applied to slope prevention engineering, landslide disasters, ground collapse, and ground settlement monitoring.
