Abstract:
1. A train car-to-car communication device comprising: a terminal provided in a composition including one or more cars of a train for transmitting and receiving information; an intra-composition transmission line connected to the terminal within 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 information from the terminal within the composition and transmitting the first information to the other adjacent composition, and receiving second information as 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 composition-to-composition communication relay units of adjacent compositions and transmitting the information, wherein the composition-to-composition communication relay unit includes composition direction determining means for determining a difference between composition directions of composition as a transmission source of 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, wherein the direction-dependent information is a discrimination information of door left and door right.
