The system for determining the position in automatic doors of the invention is intended to control the speed of the forward motion or backward motion of automatic doors and consequently to control the opening and closing operations. The system can be applied in general to any type of doors and particularly to doors used in railway wagons. The system is comprised of the functional association of means for reading the voltage and current of a direct current motor (1), from which two analog signals are generated and which, through analog/digital converters (5, 5') are transformed into digital signals in order to be compared and processed by a microcontroller (6) which, through a program, calculates the position as a function of the read variables, and according to the calculated position the microcontroller sends actuation instructions to the motor control unit (7).

Le système permettant de déterminer la position de portes automatiques, décrit par l'invention, est destiné à commander la vitesse du mouvement vers l'avant et de retour de portes automatiques et, par conséquent, les manoeuvres d'ouverture et de fermeture des portes. Ce système s'applique en général à tous types de portes et en particulier à celles qui sont utilisées dans les wagons de train. Le système consiste en l'association fonctionnelle de moyens de lecture de tension et de courant d'un moteur à courant continu (1), à partir desquels deux signaux analogiques sont générés lesquels, par l'intermédiaire de convertisseurs analogiques/numériques (5, 5'), sont transformés en signaux numériques qui sont comparés et traités par un microcontrôleur (6). Le microcontrôleur, par l'intermédiaire d'un programme, calcule la position en fonction des variables lues et, à partir de cette position calculée, envoie les instructions d'actionnement à l'unité de commande (7) du moteur.
