Abstract

The invention discloses a distributed optical fiber temperature measurement system and method, and relates to the technical field of optical fiber temperature measurement, and the system comprises a central mainboard, and an optical signal processing module, a data integration module and a fixed-area temperature control module which are electrically connected to the central mainboard, and the optical signal processing module, the data integration module and the fixed-area temperature control module are electrically connected. The optical signal processing module comprises an optical signal transmitting module and an optical signal receiving module, the optical signal transmitting module transmits optical pulse data into optical fibers to detect the temperature of an arrangement area, the temperature data is measured by the optical fiber sensors, and the optical signal receiving module receives the temperature data measured by the optical fiber sensors and sends the temperature data to the optical fiber sensors; according to the invention, the temperature fitting module is used for fitting a plurality of nodes of the temperature of the non-arrangement area, so that the temperature of the non-arrangement area is calculated.

Description

technical field [0001] The invention relates to the technical field of optical fiber temperature measurement, in particular to a distributed optical fiber temperature measurement system and method. Background technique [0002] Optical fiber is short for optical fiber. It is a fiber made of glass or plastic, which can be used as a light transmission tool. The tiny optical fiber is encapsulated in a plastic sheath, so that it can be bent without breaking. The transmitting device uses a light-emitting diode or a laser to transmit the light pulse to the optical fiber, and the receiving device at the other end of the optical fiber detects the pulse using a photosensitive element. The temperature is different, and the necessary temperature measurement correction processing is required. [0003] The main temperature measurement method is to use the distributed optical fiber temperature sensing technology, which mainly uses the correlation between the intensity of the Raman scatte...
