ACOUSTIC DETECTION OF DEFECTS IN RAIL AT HIGH SPEED

摘要

A rail defect detection device, method, and vehicle therefor includes a first sensor that receives a first acoustic signal representing contact between a train and a rail, and generates a first output signal; a second sensor that receives a second acoustic signal representing contact between the train and the rail, and generates a second output signal; a location sensor that generates a location data; a processor that compares the first output signal and the second output signal with a reference signal, and generates a detection data; and a memory that stores at least one selected from the first output signal, the second output signal, the location data, the reference signal, or the detection data.
