Application of distributed fiber optic sensing in mine for methanedetection,

摘要

Abstract: Distributed fiber optic sensing for methane detection is put forward based on the characteristics of supported catalytic sensor (SCS) in this paper. By making use of the relationship between methane gas density (MGD) and SCS's working temperature, it is possible to convert the distribution detection of MGD to that of temperature. Initial experiment results prove that this method is feasible for the measurement of MGD distribution. !2
