Abstract
The invention provides a miniaturized fluorescent optical fiber temperature measurement system, and solves the problems that an existing photoelectric demodulation module is relatively tedious in optical device installation mode and relatively large in size. The temperature measurement system comprises a PCB and at least one temperature measurement module unit arranged on the PCB. Each temperaturemeasurement module unit comprises two temperature measurement modules which are symmetrically arranged on two substrate surfaces of the PCB respectively; each temperature measurement module comprisesa mounting base, a photoelectric detector, and a circuit board, a light emitting diode, an optical fiber connector, a ball lens and an optical filter which are positioned in the mounting base; the optical fiber connector is arranged outside the front part of the mounting base; the circuit board is used for exciting the light-emitting diode to emit light beams, the light beams are incident to theoptical filter, filtered and reflected by the optical filter, incident to the spherical lens, condensed by the spherical lens and transmitted to the external optical fiber; the photoelectric detectoris used for receiving the light beam transmitted by the external optical fiber and transmitted by the spherical lens and the optical filter; and the two temperature measurement modules of each temperature measurement module unit are fixed on the PCB through bolts.
Description
technical field [0001] The invention belongs to the field of fluorescent optical fiber measurement, in particular to a miniaturized fluorescent optical fiber temperature measurement system. Background technique [0002] At present, the fluorescent optical fiber temperature control system consists of a temperature demodulation module, an optical fiber interface, and a temperature measurement optical fiber containing fluorescent substances. The temperature measurement optical fiber is connected to the temperature demodulation module through the optical fiber interface, and the temperature demodulation module is embedded in the shell of the temperature demodulator. , only the optical fiber interface is exposed. One end of the temperature measuring optical fiber is connected to the temperature demodulator, and the other end contains a fluorescent substance embedded in the measured temperature point. The excitation light source in the temperature demodulator excites the fluoresc...
