Abstract

Un système de télémesure et de commande est destiné à être utilisé dans un réseau à courant continu, tel que celui d'une automobile ou d'un autre type de véhicule. Le système comprend un émetteur pilote (10) qui code des données telles qu'une série d'impulsions électriques modulant la tension de l'alimentation en courant alternatif. Situé en un autre emplacement, un émetteur asservi (14), relié à la même source d'alimentation (2) par le réseau pré-existant, amplifie la modulation de tension d'alimentation, récupère la forme d'onde des données, et décode ces données pour procéder à une intervention ou à l'affichage d'une mesure ou d'une indication d'état. Un deuxième émetteur (15), combiné à cet émetteur asservi, peut transmettre de manière analogue des données destinées à être reçues par un deuxième récepteur (11) combiné à l'émetteur pilote, établissant ainsi entre ces deux appareils une communication à deux sens. Le système compte au nombre de ses applications possibles celles de stimulation d'urgence de batterie, dispositif anti-vol par débranchement de batterie, système d'alarme, réception et activation de données provenant d'appareils extérieurs et lecture à distance de mesures de niveaux de fluides, de températures et de pressions.
