  • System and method for early train detection
    Patent number: 9327744
    Abstract: 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: Grant
    Filed: June 18, 2015
    Date of Patent: May 3, 2016
    Assignee: WAVETRAIN SYSTEMS AS

  • System and method for early train detection
    Patent number: 9067608
    Abstract: 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.
