Abstract

PURPOSE:To make accurate the control timing, by constituting the broadcasting timing control all performed at the station side and reducing the load of the delivery line and the central processing unit. CONSTITUTION:In the automatic broadcast unit performing various broadcast by providing the station receivers 4a...4n receiving the instruction of the central processing unit 2 via the transmitter 3 and the audio generators 5a...5n converting the output signal of the receivers into audio, the relay interlocking units 6a...6n outputting the track circuit information such as access of trains are provided. Further, the station control units 7a...7n which determines the timing of broadcast and the traffic address of the audio producing units 5a, 5n with the output of the units 6a... 6n, failure detectors 8a...8n detecting the failure of the units 7a...7n, and selectors 9a...9n which select the traffic address to specific address with the output signal of the detectors 8a...8n and the output of the units 6a...6n into the audio producing units 5a...5n, are provided.
