According to the distributed system fiber optic sensor technology, the linear fiber optic fire accident monitoring system utilizes the sensitivity of diffuse light to temperature, maintaining accurate measurement of temperature changes. Distributed system fiber optic temperature sensing technology is a type of controller that uses all transmission fibers, and all fibers (optical cables) have the function of transmission and sensing technology. In the software of distributed system fiber optic temperature sensing technology system, when strong pulse light data signals are transmitted in the fiber optic cable (optical cable), the interaction force between the laser single pulse and the fiber molecular structure causes many weak backward scattering, including Rayleigh scattering, Raman scattering, and Brillouin scattering. Raman scattering is caused by thermal vibrations in the molecular structure of optical fibers, resulting in two types of light: non temperature sensitive Stokes light and temperature sensitive anti Stokes light. Each point in the optical fiber often has a very weak reverse transmission of laser data signals, which can be divided into Rayleigh scattering, Raman scattering, and Brillouin scattering. The compressive strength of the Raman scattering data signal is related to the temperature of the point, and the temperature distribution of all fiber controllers is obtained by testing the compressive strength of each point in the Raman scattering data signal. The laser emits a single pulse from the laser, which is coupled to the continuous fiber and generates transmission at each location. Using a photoelectric conversion module to convert the transmission spectrometer into electronic signals, and then expanding it, the collection module is used to solve noise reduction. The relative electronic signal of diffused light was calculated using a time-domain reflection surface manipulation module, and the temperature and position information of diffused light were obtained.
