Abstract

Système de mesure. Il comprend une paire de postes de détection, espacés d'une distance connue le long d'un trajet de déplacement du véhicule, chaque poste de détection comprenant une série d'émetteurs de rayonnement électromagnétique s'étendant verticalement, disposés sur un côté du trajet et au moins un détecteur disposé de l'autre côté. Les faisceaux des émetteurs sont dirigés vers le détecteur de sorte que chacune des parties du véhicule qui se trouve entre les émetteurs et le détecteur intercepte certains des faisceaux pour produire une variation caractéristique du rayonnement électromagnétique incident sur le détecteur qui a pour fonction d'identifier cette partie de véhicule. Des moyens de traitement de données agissent aux sorties des détecteurs aux deux postes pour fournir une mesure du véhicule en relation avec la vitesse. Application notamment à la mesure de la longueur d'un véhicule en déplacement.Measuring system. It includes a pair of sensing stations, spaced a known distance along a path of travel of the vehicle, each sensing station comprising a series of vertically extending emitters of electromagnetic radiation disposed on one side of the path. and at least one detector arranged on the other side. The beams of the emitters are directed towards the detector so that each part of the vehicle which is between the emitters and the detector intercepts some of the beams to produce a characteristic variation of the electromagnetic radiation incident on the detector which has the function of identifying this part of vehicle. Data processing means act at the outputs of the detectors at the two stations to provide a measurement of the vehicle in relation to the speed. Application in particular to the measurement of the length of a moving vehicle.
