এর বৈশিষ্ট্য distributed fiber optic stress sensing system

The characteristics of the distributed fiber optic stress real-time monitoring system are large sensing range, high accuracy, zero electrical noise, and high reliability, which can achieve multi-directional simultaneous measurement of the measured object.

Composition of Distributed Fiber Optic Stress System

The distributed fiber optic system mainly consists of detection optical cables, distributed fiber optic stress analyzers, and backend computer monitoring and alarm systems. Distributed fiber optic sensors use detection optical cables directly laid on the measured object to achieve signal acquisition; Then, the signal is transmitted to a distributed fiber optic stress analyzer through optical cables. The distributed fiber optic temperature analyzer transmits signals to the computer after program processing, and the computer system implements data processing, fault diagnosis, alarm and control.

Principle of Distributed Fiber Optic Stress Sensing System

The main principle of the distributed fiber optic stress real-time monitoring system is to utilize the sensitivity of Brillouin scattering light to temperature and strain, which can detect temperature and strain changes at different positions along the fiber optic cable. When the temperature along the fiber changes or there is axial strain, the frequency of the reverse Brillouin scattering light in the fiber will drift. The frequency drift has a good linear relationship with the changes in fiber strain and temperature. সুতরাং, by measuring the frequency drift of the natural Brillouin scattering light from the square system in the fiber, the distribution information of temperature and strain along the fiber can be obtained. Suitable for stress and temperature measurement of oil, gas, and petrochemical pipelines, as well as temperature and stress monitoring of dam structures, bridge and railway structures, overhead cables, submarine cables, and offshore platform lifting device structures.
