Patent

CA 2487525

The invention concerns a device for remote reading of states, comprising a communication network (1), a plurality of peripherals (31 to 33) each of which adopts an instantaneous state (STAT_1 to STAT_3), and a controller (2) periodically scanning said peripherals (31 to 33) to read therefrom the instantaneous state (STAT_1 to STAT_3). The invention is characterized in that the communication network (1) electromagnetically connects the peripherals (31 to 33) to the controller (2), and said peripherals (31 to 33) are supplied with electrical energy via said communication network (1). The invention is useful for managing calls in lifts by means of peripherals not provided with any galvanic connection and with any individual power source.

L'invention concerne un dispositif de télérelevé d'états, comprenant un réseau de communication (1), une pluralité de périphériques (31 à 33) dont chacun adopte un état instantané (STAT_1 à STAT_3), et un contrôleur (2) scrutant périodiquement ces périphériques (31 à 33) pour en relever l'état instantané (STAT_1 à STAT_3). Selon l'invention, le réseau de communication (1) relie les périphériques (31 à 33) au contrôleur (2) par voie électromagnétique, et ces périphériques (31 à 33) sont alimentés en énergie électrique par l'intermédiaire de ce réseau de communication (1). Application à la gestion d'appels dans les ascenseurs au moyen de périphériques dépourvus de toute liaison galvanique et de toute source individuelle d'énergie.
