Distributed fiber optic temperature sensing technology temperature compensation

Temperature measurement is an important parameter for detection and control, which has always been valued by people. In today’s rapidly developing technology, the measurement of temperature information has more profound significance. Distributed fiber optic temperature sensing technology has become a remarkable new technology in fiber optic sensing technology due to its continuous and real-time measurement of the temperature field distributed along the fiber optic. This technology has been widely applied in the fields of power industry, petrochemical industry, aerospace industry, nuclear industry, njl. The common distributed fiber optic temperature measurement method is to obtain the light intensity ratio of anti Stokes and Stokes, then attenuate and compensate for the ratio data, and finally obtain the temperature through demodulation formula. Nangona kunjalo, in practical applications, the signal received by the photoelectric detection module is not the intensity of the anti Stokes light and Stokes light at different positions in the fiber, but the intensity of the backward propagation and attenuation loss of the anti Stokes light and Stokes light in the fiber. Ngoko ke, it is necessary to compensate for the attenuation of the signal received by the photoelectric detection module.

The distributed fiber optic temperature measurement method fits the intensity ratio signal of anti Stokes light and Stokes light in segments based on the attenuation point data of the fiber optic. Emva koko, the actual obtained ratio line data is divided by the fitted baseline data, and the division result is calibrated to obtain the fiber optic temperature. This invention extends the application of ifayibha optic umlinganiselo wobushushu obusasaziweyo
Even with poor fiber quality, normal temperature measurement can still be carried out within a certain range. Ukwengeza, the segmented method is used to attenuate and compensate for the light intensity ratio signal of anti Stokes and Stokes, so that the temperature curve demodulated by the system is consistent with the actual situation, thereby improving the temperature measurement accuracy and reliability of the temperature measurement system.
