Abstract:
1. A train information transmitting and receiving system comprising: information transmitting and receiving apparatuses that are mounted on a plurality of vehicles constituting a train, respectively, and perform a train information process in coordination with each other; first and second vehicle-side connectors that are respectively set on both ends of each of the vehicles and respectively have a ground terminal that is grounded to each of the vehicles and a plurality of signal transmission-path terminals; first and second in-vehicle wiring cables that have a plurality of signal transmission paths that respectively connect the plurality of respective signal transmission-path terminals of the first and second vehicle-side connectors and the information transmitting and receiving apparatuses, and shielding layers that are grounded to the vehicles and shield the signal transmission paths; and a vehicle connection cable that is mounted, at both ends, with first and second connectors that respectively have connection ground terminals and a plurality of connection-signal transmission-path terminals configured to be respectively engaged with ground terminals and with a plurality of signal transmission-path terminals of the first and second vehicle-side connectors, and has a plurality of connection-signal transmission paths that connect the connection-signal transmission-path terminals of the first and second connectors, and has a single shielding layer that shields a whole of the connection-signal transmission paths by surrounding the whole of the connection-signal transmission paths and is connected to only any one of the respective connection ground terminals of the first and second connectors, wherein a transmission path between adjacent vehicles is constituted by connecting the first vehicle-side connector of one of the adjacent vehicles with the first connector of the vehicle connection cable and connecting the second vehicle-side connector of another one of the adjacent vehicles with the second connector of the vehicle connection cable.
