Abstract

PURPOSE:To reduce the number of persons required for the guide broadcast of approach of the train to the station and respond to approach of the train immediately, by transmitting the broadcast in the train to the outside with a weak radio waves and by receiving it by the station to broadcast by the speaker connected to wire broadcasting. CONSTITUTION:Transmitter 9 is connected to cab microphone 2 provided in train 1, and the broadcast is performed from cab speaker 4 by cab broadcasting device 3, and simultaneously, the weak radio wave signal is transmitted to the outside by the transmission antenna connected to transmitter 9. Meanwhile, receiving antenna 12 to receive this weak radio wave signal is arranged in station 5. This receiving antenna 12 is connected to receiver 11, and the guide broadcast for passengers in train 1 is broadcasted in the yard of station 5 simultaneously by yard speaker 8 connected to wire broadcasting device 7.
