Abstract

Dispositif permettant de coder des positions géographiques. Il comprend : un détecteur de proximité inductif contenant sa propre bobine d'induction 13 et une bobine 12, concentrique à la précédente mais de fréquence identique. Un récepteur statique contenant une bobine accordée 1 de réception du signal de la bobine 12 du détecteur de proximité inductif, des convertisseurs alternatifs continus 3, 8 de ce signal, un générateur de code 7 et un interrupteur statique 5 qui met en oeuvre un circuit résonnant série L, C 6, 2 qui absorbe ou non, au rythme du code et par courants de Foucault, le champ électromagnétique reçu par la bobine 13 du détecteur quand la bobine 1 du récepteur statique est en regard de la face de détection 20. Un conformateur de code 23, consistant en un dispositif d'échantillonnage, géré par un micro-processeur 25 qui remet le code obtenu en sortie 22 du détecteur de proximité inductif aux normes de transmission, ce code est transmis en série sur une ligne 24 unique. L'invention peut être utilisée pour le codage de positions géographiques, pour l'auto-contrôle de détecteurs de proximité dans des applications de sécurité et pour la commande d'automates.
