The invention relates to a method for measuring the speed of a vehicle fitted with an antenna and travelling on a track with two rails in the form of track sections (1, 2, 3), known as block systems which are separated by electric joints, whereby each electric joint is made up of two tuning blocks (TU.F1 and TU.F3) and a predetermined track section located therebetween, whereby power coupling is provided for the adjacent track section acting as a block system by each of the tuning blocks (TU.F1 and TU.F3). The invention is characterized by detection of at least two discontinuities in the current or in the voltage of the signal as seen by an antenna which is present in the vehicle travelling on the track in the immediate vicinity of the first and second tuning blocks (TU.F1 and TU.F3) of the same electric joint in order to measure the speed of the vehicle travelling on said track. The invention also relates to an installation for carrying out the inventive method.
La présente invention se rapporte à un procédé de mesure de la vitesse d'un véhicule muni d'une antenne et circulant sur une voie à deux rails se présentant sous la forme de sections de voie appelées "cantonnements" (1, 2, 3) séparées par des joints électriques, chaque joint électrique étant constitué de deux blocs d'accord (TU.F1 et TU.F3) et de la section de voie prédéterminée située entre eux, chacun des blocs d'accord permettant le couplage en énergie pour la section de voie adjacente servant de cantonnement, caractérisé en ce que l'on détecte au moins deux discontinuités en courant ou en tension du signal vu par une antenne présente dans le véhicule circulant sur la voie aux abords des régions des premier et second blocs d'accord (TU.F1 et TU.F3) d'un même joint électrique, en vue de mesurer la vitesse du véhicule circulant sur la voie. La présente invention se rapporte également à l'installation pour la mise en oeuvre de ce procédé.
