Abstract

Système de signalisation en courant continu sur ligne à deux fils avec circuit de régulation et de protection incorporé. Il comprend deux résistances de ligne 11, 13 montées en point de Herter avec quatre autres résistances 21 à 24. Le premier accès du pont est connecté au générateur de courant continu via des commutateurs électroniques 5, 46 et 19, 45, le second à la charge 1 et le troisième à un amplificateur différentiel 27 fournissant un signal proportionnel à la somme des courants des deux fils de ligne 3, 4. La régulation est associée en commandant les commutateurs en fonction de ce signal, via un modulateur de largeur d'impulsions 38. Un deuxième amplificateur différentiel 57, dont les entrées sont connectées au premier accès via des différentiateurs, assure une détection précise des ouvertures et fermetures de boucle 2. Application comme interface de téléimprimeur pour réseau télex.DC signaling system on two-wire line with built-in regulation and protection circuit. It includes two line resistors 11, 13 mounted in Herter point with four other resistors 21 to 24. The first access of the bridge is connected to the direct current generator via electronic switches 5, 46 and 19, 45, the second to the load 1 and the third to a differential amplifier 27 supplying a signal proportional to the sum of the currents of the two line wires 3, 4. The regulation is associated by controlling the switches according to this signal, via a pulse width modulator 38. A second differential amplifier 57, the inputs of which are connected to the first port via differentiators, ensures precise detection of the openings and closings of loop 2. Application as a teleprinter interface for a telex network.
