The device of the invention provides for the detection of the presence and the direction of passage of mobiles, with a view to their counting, without requiring ground infrastructure. The device comprises two emitters of the infrared diode type (1 and 4). A mobile cutting the beam emitted by the first infrared emitter (1) reflects said beam. A signal is then received by the first reception element (3). The mobile continuing its displacement cuts the beam emitted by the second infrared emitter (4). A signal is then received by the second receiver element (2). The chronology of the signals received by the receiver elements enables to determine the direction of passage of the mobiles. An electronic embodiment provides for the control of emission elements (1 and 4) and the processing of the signals received by the receiver elements (2 and 3), with a view to counting the mobiles. The device of the invention is particularly intended to the counting of persons coming in and going out of transport means (underground, train, bus) or in a public or private place, to the counting of objects conveyed on a conveyor belt, as well as to the counting of vehicles.
Le dispositif selon l'invention permet de détecter la présence et le sens de passage de mobiles, en vue de leur comptage, sans nécessiter d'infrastructure au sol. Le dispositif comporte deux émetteurs de type diode infrarouge (1 et 4). Un mobile coupant le faisceau émis par le premier émetteur infrarouge (1), réfléchit ce faisceau. Un signal est alors reçu par le premier élément de réception (3). Le mobile continuant son déplacement coupe le faisceau émis par le second émetteur infrarouge (4). Un signal est alors reçu par le second élément de réception (2). La chronologie des signaux reçus par les éléments de réception permettent de déterminer le sens de passage des mobiles. Une réalisation électronique permet de piloter les éléments d'émission (1 et 4) et de traiter les signaux reçus par les éléments de réception (2 et 3), en vue du comptage. Le dispositif selon l'invention est particulièrement destiné au comptage de personnes entrant et sortant d'un moyen de transport (métro, train, bus) ou d'un lieu public ou privé, au comptage d'objets passant sur un tapis roulant, ainsi qu'au comptage de véhicules.
