Description

technical field [0001] The present invention relates to the field of temperature detection equipment, in particular to a multi-point temperature detection integrated device integrating multiple temperature detection points, and also relates to a multi-point temperature detection system using the multi-point temperature detection integrated device. Background technique [0002] The temperature measurement principle of the existing optical fiber sensing technology is based on the material characteristics of rare earth fluorescent substances. After some rare earth fluorescent substances are irradiated and excited by ultraviolet rays, they emit linear spectra in the visible spectrum, that is, fluorescence and afterglow (afterglow is the excitation stop after the glow). The decay time constant of fluorescence afterglow is a single-valued function of temperature, and generally the higher the temperature, the smaller the time constant. As long as the value of the time constant is ...
