Abstract
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.
Claims15
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.
Apparatus for 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, the apparatus comprising:
- at least two acoustic transducers each having an optical fiber proximate the railway, said optical fibers picking up acoustic signals;
- at least two receivers for receiving the acoustic signals from the at least two acoustic transducers;
- and
- processing means for:
- analyzing the received signals,
- identifying a signature associated with said train from said received signals,
- determining the speed of said train from analysis of said signatures, and
- estimating the arrival time of the train using the determined speed.
