Distributed optical fiber vibration sensor vibration source transverse positioning method and system

Abstract

The invention discloses a transverse positioning method for a vibration source of a distributed optical fiber vibration sensor. The transverse positioning method comprises steps of S1, acquiring space-time vibration data of optical fiber spatial distribution caused by a single-point vibration source; S2, calculating the position of an optical fiber axial vibration center, closest to a vibration source, on the sensing optical fiber according to the space-time vibration data; S3, respectively acquiring vibration data wave widths delta t1 and delta t2 of the optical fiber axial vibration center and a monitoring point spaced from the optical fiber axial vibration center by a distance d through the vibration space-time data; and S4, obtaining a transverse distance between the vibration source and the axial vibration center of the optical fiber according to the seismic wave dispersion principle. The method is advantaged in that the transverse position information of the vibration source canbe obtained through a very small amount of calculation, and misinformation in practical application is greatly reduced.
