Title
(EN) METHOD AND APPARATUS FOR THE EXCLUSIVE IDENTIFICATION OF CONTROL SIGNALS IN A RAILWAY ELECTRIC LINE
(FR) PROCÉDÉ ET DISPOSITIF D'IDENTIFICATION EXCLUSIVE DE SIGNAUX DE COMMANDE LE LONG D'UNE LIGNE DE CHEMIN DE FER ÉLECTRIQUE
Abstract
(EN) Apparatus for exclusive identification of control signals along an alternating current power supply (A), consisting of a plurality of power cables which connect a central unit (C) to a plurality of signal devices (L), characterised in that it comprises a circuit for transmitting such power supply signals adapted to associate to each of the power supply signals an unambiguous code word to each device to be supplied with power which consists in providing a preset number of positive negative half- waves in the alternating power supply signal according to a predetermined sequence, at least a block (2,2') for extracting the power supply signal from each cable of the line and at least one processing block (3,3') adapted to compare such predetermined unambiguous codes with the extracted signals.
(FR) L'invention concerne un dispositif d'identification exclusive de signaux de commande le long d'une alimentation électrique C.A. (A) qui comprend plusieurs câbles d'alimentation reliant une unité centrale (C) à plusieurs dispositifs à signaux (L). Ce dispositif comporte un circuit de transmission, transmettant à chaque dispositif destiné à être alimenté en énergie ces signaux d'alimentation associés chacun à un mot de code non ambigu. On y parvient en fournissant un nombre préétabli de demi-ondes négatives positives dans le signal d'alimentation C.A. suivant une séquence prédéterminée. Un bloc (2, 2') est capable d'extraire le signal d'alimentation depuis chaque câble de la ligne et un bloc de traitement est conçu pour comparer ces codes préétablis non ambigus aux signaux extraits
