INFORMATION TRANSMISSION DEVICE

摘要

PROBLEM TO BE SOLVED: To detect a stop position of a train and transmit various control information between the train and the ground by simplifying constitutions of a on-vehicle device and a ground device.

SOLUTION: On-vehicle information is transmitted to the ground from a train 1 by a vehicle information transmitter 4. A vehicle information receiver 13 of a ground device 3 receives the transmitted on-vehicle information via two loop coils 17a, 17b of an information receiving coil 12 installed near a stop reference position 18 in a station. A station control device 14 judges a position of a train according to whether any one or both of the two loop coils 17a, 17b of the information receiving coil 12 receives the information, and transmits the judged results to an ATC transmitter 16b as the train stop position information. The ATC transmitter B transmits the train stop position information to the train 1 by carrying it on the ATC signals.
