Optical fiber distributed temperature measurement method for fire safety analysis of wooden buildings

Popis výsledku v původním jazyce

This article deals with the issue of fire safety monitoring of wooden buildings. Wooden buildings currently represent a quick and relatively inexpensive option for acquiring a family house. However, with regard to the building material and its flammability, the construction possibilities are strongly regulated by standards. The aim of this paper is to describe the possibilities of monitoring temperature changes during a simulated fire using optical fiber and a distributed temperature measurement system (DTS). The DTS system uses the principle of stimulated Raman scattering, which allows longitudinal temperature measurements with a spatial resolution of 1 m. The increase in spatial resolution was achieved by winding the optical fiber into 5 cm diameter rings, with a fiber length of 3 m in each ring. The measuring rings of optical fiber were attached to fabric arranged in a rectangular grid. This fabric with the rings was then placed at the surveyed locations in the construction panels. During the temperature loading of the test samples with the gas torch, temperature monitoring was carried out both on the reverse side of the samples and in the inner layers. The results showed that this system with conventional multimode optical fibers can measure temperatures ranging from 20 degrees C to approximately 500 degrees C. This method offers the possibility to accurately monitor the temperatures of wooden buildings, including the inner layers of the building panels. The proposed method can therefore be used to thoroughly verify the fire safety of wooden buildings and their components.
