Abstract:
(EN) Device for detecting the presence of an object close to or within an door opening defined by two door sections comprising at least one sensor at each door sec- tion. Each sensor comprising at least one reference conductor and at least one sensing line insulated and distant from the at least one reference conductor. The at least one sensing line being connected to an amplifier generating an output signal indicating the signal strength and/or attenuation of a signal at the at least one sensing line. A control circuit is provided, further comprising a signal genera- tor and a switch unit having at least a first output and a second output, whereas in a first measurement mode A, the first output is connected to the signal gener- ator and the second output is connected to ground, and in a second measure- ment mode B, the first output is connected to ground and the second output is connected to the signal generator. An evaluation unit is provided for correlating an output signal measured in mode A with an output signal measured in mode B.
(FR) Cette invention concerne un dispositif de détection de la présence d'un objet à proximité ou à l'intérieur d'une ouverture de porte définie par deux sections de porte comprenant au moins un capteur sur chaque section de porte. Chaque capteur comprend au moins un conducteur de référence et au moins une ligne de détection isolée et distante dudit/desdits conducteur(s) de référence. Ladite/lesdites ligne(s) de détection est/sont connectées à un amplificateur générant un signal de sortie indiquant l'intensité de signal et/ou l'atténuation d'un signal sur ladite/lesdites ligne(s) de détection. L'invention concerne de plus un circuit de commande, comprenant en outre un générateur de signal et une unité de commutation ayant au moins une première sortie et une seconde sortie. Dans un premier mode de mesure (A), la première sortie est connectée au générateur de signal et la seconde sortie est connectée à la masse, et dans un second mode de mesure (B), la première sortie est connectée à la masse et la seconde sortie est connectée au générateur de signal. Une unité d'évaluation est fournie pour corréler un signal de sortie mesuré dans le mode A avec un signal de sortie mesuré dans le mode B.
