Title:
DETECTION METHOD AND APPARATUS APPLIED TO RAILWAY TRACK, AND DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/207346
Kind Code:
A1
Abstract:
Provided are a detection method and apparatus applied to a railway track, and a detection device. Optical fibers are laid on both sides of a railway track. The detection apparatus comprises: a first processing module (92), a second processing module (94) and a third processing module (96). The detection method comprises: acquiring, by using a first processing module (92), a first measurement signal, which is generated by an optical fiber laid on one side of a railway track, and generating a first curve on the basis of the first measurement signal; acquiring, by using a second processing module (94), a second measurement signal generated by an optical fiber laid on the other side of the railway track, and generating a second curve on the basis of the second measurement signal; and acquiring, by using a third processing module (96), the amplitude difference between the first curve and the second curve regarding the same distance, and on the basis of the amplitude difference, performing detection on the railway track or wheels, which travel on the railway track.
