Abstract

Système de bus numérique pour aéronef Système de bus numérique dans un aéronef entre un module de contrôle (120) d’un calculateur d’aéronef et une pluralité de capteurs et/ou d’actionneurs de cet aéronef regroupés autour de nœuds de capteurs (14.2) et/ou de nœuds d’actionneurs (15.2) respectivement, le système comprenant d’une part une liaison de communication bifilaire (40) pour transférer à la fois une tension d’alimentation et des données entre le module de contrôle et les nœuds de capteurs et/ou d’actionneurs selon un procédé d’accès multiple à répartition dans le temps dit TDMA combiné à une modulation par multiplexage fréquentiel orthogonal dite OFDM et d’autre part une liaison de puissance bifilaire (42) pour amener depuis un générateur de puissance externe (44) de la puissance aux seuls actionneurs. Figure pour l’abrégé : Fig. 3.Digital bus system for aircraft Digital bus system in an aircraft between a control module (120) of an aircraft computer and a plurality of sensors and/or actuators of this aircraft grouped around sensor nodes (14.2 ) and/or actuator nodes (15.2) respectively, the system comprising on the one hand a two-wire communication link (40) for transferring both a supply voltage and data between the control module and the nodes sensors and/or actuators according to a time division multiple access method called TDMA combined with orthogonal frequency multiplexing modulation called OFDM and on the other hand a two-wire power link (42) to bring from a generator external power supply (44) from the power to the actuators only. Figure for abstract: Fig. 3.
