A purpose of the invention is to obtain a train car-to-car communication network capable of continuous communication processing without disruption of communication processing when compositions in different composition directions are coupled. A train car-to-car communication device includes: a terminal; an intra-composition transmission line connected to the terminal within the same composition for transmitting the information; a composition-to-composition communication relay unit connected to the intra-composition transmission line for receiving first information as the information from the terminal within the composition and transmitting the first information to the other adjacent composition, and receiving second information as the information from the other adjacent composition and transmitting the second information to the terminal within the composition of interest; and a composition-to-composition transmission line for connecting the composition-to-composition communication relay units of the adjacent compositions and transmitting the information, and the composition-to-composition communication relay unit has composition direction determining means for determining a difference between composition directions of the composition as a transmission source of the received information and the composition to which the composition-to-composition communication relay unit of interest belongs, and direction-dependent information rewriting means for rewriting to invert direction-dependent information contained in the received information if the composition direction determining means determines that the composition directions are different.
L'invention porte sur un réseau de communication entre véhicules ferroviaires. Lorsque des compositions de direction de compositions différente sont réunies, ledit réseau peut supporter un traitement de communication sans interruption. L'appareil de communication entre véhicules ferroviaire comporte un terminal ; un trajet de transmission en composition connecté aux terminaux de la même composition pour transmettre les informations ; un dispositif de relais de communication inter-composition connecté au trajet de transmission d'une composition pour recevoir des premières informations d'un terminal de la composition et les transmettre à une autre composition adjacente, et pour recevoir des secondes informations de l'autre composition adjacente et les transmettre à un terminal de la composition ; et un trajet de transmission inter-composition pour connecter le dispositif de relais d'intercommunication dans les compositions adjacentes et transmettre des informations. Le dispositif de relais d'intercommunication est muni de moyens de détermination de direction de composition pour déterminer la différence de direction de composition entre la composition de l'origine de transmission des informations reçues et la composition concernée ; et de moyens de réécriture d'informations de dépendance de direction pour réécrire des informations de dépendance de direction incluses dans les informations reçues de façon à inverser les mêmes informations lorsque les moyens de détermination de direction de composition déterminent que la direction de composition est différente.
