Railway system using acoustic monitoring

摘要

A method of monitoring and/or controlling components of a railway system which includes a track and at least one train that is operable to run on said track, comprises the steps of: a) providing an acoustic transducer proximate the railway for picking up acoustic signals; b) receiving acoustic signals from the transducer; and c) analyzing the received signals.

主权项

1. A method for predicting the time at which a train will arrive at a level crossing, the method comprising the steps of:
a) providing at least two spaced apart acoustic transducers, each having an optical fiber proximate a train track, the optical fibers picking up acoustic signals; b) monitoring signals received from said transducers; c) identifying a signature associated with said train from said received signals; d) determining the speed of said train from analysis of said signatures; and e) estimating the arrival time of the train using the determined speed.
