<p>PURPOSE:To obtain an information transmission system which has a simple system construction and high reliability by transmitting data when a position detection signal transmitted from the ground and a position detection signal on a train coincide. CONSTITUTION:When a train 1 enters closed sections 1T-nT, relays TR1-TRn of a train detector 8 are deenergized. An encoder 93 transmits information of an information generator 92 in response to a position signal of a train position detector 92 of a train device, not shown to loop antennas 31-3n provided at the entrance points of the sections 1T-nT. The train device reads out control information when train position information received by a train antenna and train position information detected by the own train position detector coincide with each other.</p> |
