Abstract

The invention discloses a distributed optical fiber temperature measurement system, which includes several optical fiber sensors for detecting the temperature of the arrangement area; an optical signal processing module for processing the optical signal transmitted by the optical fiber sensor and calculating the temperature of the arrangement area. temperature; a temperature fitting module, which calculates the temperature of the non-arrangement area by fitting the temperature of the arrangement area; and a temperature correction module, which is used to correct the temperature of the arrangement area and the temperature of the non-arrangement area. The invention can improve the deficiencies of the prior art and increase the temperature measurement coverage density of the distributed optical fiber temperature measurement system.

Description

technical field [0001] The invention relates to the technical field of distributed optical fiber temperature measurement, in particular to a distributed optical fiber temperature measurement system and a temperature measurement method thereof. Background technique [0002] Distributed optical fiber temperature measurement technology is widely used in special equipment, mine tunnels and many other fields due to its flexible layout and can be used in flammable and explosive environments. Although the distributed optical fiber temperature measurement system has a large number of temperature measurement points, there are still temperature measurement blind spots outside the temperature measurement point. How to increase the temperature measurement coverage density without increasing hardware costs has become a distributed optical fiber measurement system. An important research direction of Wen. Contents of the invention [0003] The technical problem to be solved by the prese...
