The Application of Fiber Optic Vibration Sensors

With the continuous development of sensing technology, people’s demand for sensor technology is also increasing. It is rare for vibration sensors to simultaneously meet the conditions of high sensitivity, lae koste, simple preparation process, and good stability. In the process of sensing and detection, sensitivity and stability are the main technical influencing factors, while preparation process and cost are important influencing factors in industrial production. Vibration sensors that combine these advantages are receiving increasing attention and favor.

The importance of pipeline monitoring systems

Pypleidings is noodsaaklike materiaalvervoerfasiliteite vir belangrike stelsels soos aardgas, Olie, Stedelike verwarming, en gas. Dit is van groot belang vir die ontwikkeling van die nasionale ekonomie en die vervoer van energie en materiale. Terselfdertyd, pyplynfasiliteite het 'n groot belegging en is meestal in loopgrawe geleë of onder die grond begrawe. Hulle het 'n sekere mate van verberging in die ruimte. As dit beskadig is as gevolg van menslike of natuurlike redes, dit is moeilik om dit betyds op te spoor. Die lekkasie van vlambare en plofbare stowwe sal groot veiligheidsgevare inhou. As dit 'n brand- of ontploffingsongeluk veroorsaak, dit sal groot ekonomiese verliese meebring, en veroorsaak selfs beduidende ongevalle en sosiale wanorde.

Illegal intrusion and destructive behavior pose a serious threat to the safety of basic equipment and facilities such as military bases, communication cables, olie- en gaspypleidings, and perimeter security. Timely and accurate identification of various illegal intrusion and destructive behaviors (hereinafter referred to as disturbance signals) that endanger the safety of cables, pipelines, and security systems has important research value and practical significance.

Distributed Fiber Optic Vibration Monitoring and Security System

Fiber optic sensors, as a wavelength modulated photonic device, not only have the advantages of light weight, klein grootte, hoë akkuraatheid, reusability, korrosie weerstand, and no electromagnetic interference, but also have commercial applications. Vibration is a common phenomenon, and reasonable solutions to vibration problems in engineering practice have important engineering application value. In the pipeline vibration fiber optic monitoring device, vibration sensing monitoring and temperature monitoring for municipal pipelines such as natural gas can be used to detect and warn of natural gas pipeline infringement events and detect and analyze damage and leakage points. The sensing monitoring is achieved through the induction measurement of the pipeline through fiber optic, utilizing the advantages of fiber optic’s anti electromagnetic interference ability, convenient networking, and inherent large signal transmission bandwidth. The fiber optic vibration and temperature sensors break through the limitations of electrical sensors, providing a very effective monitoring method for environments that require explosion-proof, anti-corrosion, and even electromagnetic field interference. It realizes all-weather and all-round monitoring of the sub health status of natural gas and other pipelines through early detection and early warning.

Distributed fiber optic sensing vibration

Distributed fiber optic sensing disturbance detection technology has become the mainstream technology for intrusion behavior security monitoring due to its strong resistance to electromagnetic interference, hoë sensitiwiteit, large dynamic range, easy to quickly capture, and high-precision monitoring of dynamic change information. Egter, due to the complex and variable natural environment, optical path noise, and line scattering noise, as well as the randomness and diversity of external invasion and destructive behavior, there are substantial difficulties in improving recognition rate and reducing false alarm rate for fiber optic sensing disturbance signal detection methods. FJINNO provides a simple, fast, and accurate method and system for detecting fiber optic sensor signals, achieving fast and accurate recognition of disturbance signals.
