Monitoring track systems, involves subjecting rail bodies to transient signal at periodic intervals, detecting sound in sold signal at any point with acceleration sensor, transient recorder

摘要

The method involves subjecting the rail bodies (1) to a transient signal (5) at periodic intervals. The signal travels through the body as sound in solid material to enable detection at any point using an acceleration sensor (3) and a transient recorder (6) in order to detect changes occurring on the track.
