The Importance of Monitoring Stress Sensors

As the modernization process continues, stress sensing is an extremely important issue in the safety monitoring of the entire construction process in many monitoring systems ranging from large-scale building structures to some fine engineering structures. Tulad ng kilala, the traditional method of measuring stress is usually carried out with the continuation of modernization. In many monitoring systems ranging from large-scale building structures to some fine engineering structures, stress sensing is an extremely important issue in the safety monitoring of the entire construction process. Tulad ng kilala, ang tradisyunal na paraan ng pagsukat ng stress ay karaniwang umaasa sa halaga ng paglaban na makikita ng resistance strain gauge at ang kaukulang relasyon sa pagitan ng stress upang makita ang engineering construction. Bagama't mura ang resistance strain gauge, ang kakayahang umangkop nito sa panlabas na kapaligiran ay hindi maganda, lalo na madaling kapitan sa impluwensya ng mga electromagnetic field. Kasabay nito, hindi ito maaaring gumana sa maraming kinakaing unti-unti na kapaligiran, na isang malaking kakulangan para sa mga sensor ng stress na ginagamit sa pagtuklas ng engineering. At ang mga tradisyunal na sensor ng stress ay maaari lamang magsagawa ng mga pagsukat ng isang punto.

Mga kalamangan ng Fiber Optic Stress at Strain Sensing Monitoring

Mga sensor ng stress ng fiber optic may mga pakinabang ng maliit na sukat, magaan na timbang, Mataas na katumpakan, Walang panghihimasok sa electromagnetic, at corrosion resistance ng pangkalahatang fiber optic sensors. Samakatuwid, various fiber optic stress sensors have emerged in the development process of stress sensors. And many of them have already been commercialized. There are already many types of stress sensing structures or devices based on optical fibers. Halimbawa, sensors based on fiber micro bending structures and Fabry Perot fiber structures can be applied in many places.

Strain is an important physical property of materials and structures. The stress state of large-scale structures and engineering plays a decisive role in their safety and reliability. Tumpak, napapanahon, and comprehensive understanding of the structural health status is necessary to make a correct evaluation and avoid the occurrence of major accidents. Fiber Bragg Grating is considered one of the most promising optical passive sensor components, which has the characteristics of small size, flexibility and bendability, intrinsic na kaligtasan, and strong adaptability to harsh environments. Samakatuwid, it is necessary to design a stress detection device based on fiber optic sensing that is structurally stable and easy to install.

The fiber optic stress-strain sensing monitoring system integrates Brillouin scattering technology, optical time-domain reflection technology, high-frequency signal acquisition technology, and other technologies to achieve temperature/stress monitoring for special optical cables in different application scenarios. The fiber optic stress monitoring system has extensive applications and significant advantages in the health diagnosis of large buildings such as bridges, Mga embankment, and rail transit, as well as in the safety monitoring of oil and gas, Power Grids, and national defense and aerospace fields.
