Abstract
(EN)
A communication apparatus for rolling stock provided in rolling stock in which reliability of data transmission is enhanced by ensuring adaptability to a transmission channel of low signal quality. The communication apparatus for rolling stock comprises a node device (21) having converters (31-1, 31-2) performing mutual signal conversion between an HDLC signal flowing through an inter-vehicle network configured among the vehicles of the rolling stock and an Ethernet® signal flowing through an intra-vehicle network configured in each vehicle, and having a switching hub (32) interposed between the converters (31-1, 31-2) and interconnecting them, and network controllers (22-1, 22-2) connected with the switching hub (32).
(FR)
L'invention concerne un appareil de communication destiné à du matériel roulant et monté sur du matériel roulant, et dont la fiabilité de transmission de données est accrue grâce à l'adaptabilité d'une voie de transmission présentant une faible qualité de signal. L'appareil de communication de l'invention comprend un dispositif formant noeud (21) comprenant des convertisseurs (31-1, 31-2) permettant d'effectuer une conversion de signal mutuelle entre un signal HDLC circulant dans un réseau inter-véhicules conçu pour plusieurs véhicules du matériel roulant et un signal Ethernet® circulant dans un réseau intra-véhicule conçu pour chaque véhicule individuel du matériel roulant, et comprenant une plate-forme de commutation (32) intercalée entre les convertisseurs (31-1, 31-2) pour les interconnecter, et les contrôleurs de réseaux (22-1, 22-2) reliés à la plate-forme de commutation (32).
