Abstract

L'invention met en oeuvre une discrimination originale de signaux de différentes largeurs d'impulsion dans des interfaces 32, 32a, 34, 34a d'un système de transmission de signaux d'ordre et d'information entre une unité centrale de traitement 26 et plusieurs dispositifs de détection 22, 22a et d'actionnement 24, 24a via un seul fil de transmission 30 et un dispositif de masse 38. L'énergie d'alimentation des interfaces des dispositifs de détection et d'actionnement est délivrée par l'intermédiaire de la ligne 30, sauf lors d'une transmission d'information sur la ligne. L'invention s'applique à tout système de transmission.
