Description

TECHNICAL FIELD

They have achieved gratifying results and are also widely used in energy storage battery monitoring in the new energy field. However, optical fiber sensors are easily affected by harsh environments such as high temperature, high pressure, and strong corrosion, resulting in performance degradation. The optical fiber sensors with degraded performance cannot work normally, and there is a deviation between the signals collected by the monitoring system and the true situation of the structure, which may lead to incorrect evaluation of the health status of the measured structure.

[0003] Currently, there are three main methods for installing optical fiber sensors on the surface of steel structures: adhesive bonding, riveting, and spot welding. The adhesive bonding method has low strain transfer efficiency and poor long-term stability due to the limitations of the adhesive performance, and does not meet the requirements of long-term monitoring. The riveting method requires drilling holes on the measured structure, which destroys the original structure and is usually not allowed. The spot welding method has stable strain transfer performance, high connection strength, and does not damage the measured structure, making it suitable for long-term monitoring in harsh environments and the most ideal installation method in engineering applications.

However, the use of multiple bolts to fix the optical fiber sensor is not convenient for quick installation and positioning of the optical fiber sensor due to the limited installation space of the optical fiber sensor, which leads to poor convenience of actual installation of the optical fiber sensor.
