  • Method for measuring the speed of a rail vehicle and installation therefor
    Patent number: 7938370
    Abstract: In order to measure a speed of a vehicle having an antenna and travelling on a track formed by two rails, first and second discontinuities are detected. The first discontinuity is detected in a current or voltage of a signal generated by an antenna when the vehicle passes a first tuning block of an electric joint. The second discontinuity is detected in a current or voltage of a signal generated by the antenna when the vehicle passes a second tuning block of the electric joint. The detected discontinuities are used to measure the speed of the vehicle travelling on a track divided in track sections separated by electric joints. Each electric joint includes two tuning blocks and a predetermined length of a track section, wherein each of the tuning blocks allows power coupling between adjacent track sections.
