Patent number: 11447166Abstract: A railway track condition monitoring system including a plurality of sensors installed on a rail of the track and spaced by a predetermined distance from each other. The sensors having respective signal acquisition and recording means for the acquisition and recording of an acoustic signal being generated by an approaching train and propagated by the rail or by a ground carrying the rail. A signal transfer means for the transfer of an acquired and recorded signal to the passing train by wireless transfer at the time of passing of the train in proximity to sensors, and a signal analyzing means for analysing transferred ones of the acquired and recorded signal on-board the passing train. The signal analyzing means may be adapted to compare in a processing unit the signals from adjacent sensors and on that basis indicate a rail discontinuity.Type: GrantFiled: September 6, 2017Date of Patent: September 20, 2022Assignee: WAVETRAIN SYSTEMS ASInventor: Dominik Lang

Patent number: 9327744Abstract: Train detection security system and method for detecting a moving train are provided. The train detection security system includes one or more sensor units fixed to a rail of a rail track. The sensor units are arranged for detecting a first signal induced by a moving train and propagated through the rail. The system further includes a control unit including a signal processor arranged for receiving first sensor output signals representing the first signals from each of the one or more sensor units, processing the first sensor output signals and generating a train warning signal representing characteristics of the moving train based on envelope characteristics of the first sensor output signals.Type: GrantFiled: June 18, 2015Date of Patent: May 3, 2016Assignee: WAVETRAIN SYSTEMS ASInventors: Fredrik Lingvall, Tron Danielsen, Richard Aaroe, Torsten Amundsen, Orjan Sommerseth

Patent number: 9067608Abstract: A train detection security system and method include sensor units arranged for being fixed to at least one rail. The sensor units are arranged for detecting a first signal induced by a moving train. Each sensor unit is divided in at least a first chamber and a second chamber, where the first and second chambers are separated by an electromagnetic shield. The first chamber includes a piezoelectric element fixed to an outer wall of said first chamber, and an amplifier. A warning signal is generated in a control system based on the approaching train.Type: GrantFiled: September 16, 2011Date of Patent: June 30, 2015Assignee: WAVETRAIN SYSTEMS ASInventors: Fredrik Lingvall, Tron Danielsen
