Multi-point temperature detection integrated device and multi-point temperature detecting system

Abstract

The invention provides a multi-point temperature detection device and a multi-point temperature detecting system. The multi-point temperature detection device comprises an integrated part and an insertion head. The insertion head is obtained through end extending of the integrated part. The end of the insertion head and the end of each lead-in trough are respectively provided with corresponding number of electrical contacts. The electrical contacts of the insertion head contact with the electrical contacts of the lead-in trough. The integrated part is internally provided with a fluorescent excitation light source, a fluorescent detector, a circuit board, a filter plate and an optical fiber joint. The fluorescent detector is arranged in a manner of facing the filter plate. An optical path which comprises the filter plate and the optical fiber joint is provided with a coupling lens. The filter plate and the coupling lens are arranged in the optical between the fluorescent excitation light source and the optical fiber joint. The fluorescent excitation light source and the fluorescent detector are arranged on the circuit board. The multi-point temperature detecting system comprises the multi-point temperature detection device. According to the multi-point temperature detection device, a plurality of optical path coupling modules are integrated in one cabinet, thereby facilitating mounting and maintenance, and furthermore settling a problem of inaccurate temperature detection caused by interchangeability of the optical fiber.

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 properties of rare earth fluorescent substances. After some rare earth fluorescent substances are irradiated and excited by ultraviolet rays, they emit line-like 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 ...
