Abstract

The invention relates to receiving and amplifying and switching devices and systems of local conductive connection and public address system in motorized rolling stock, that acts as a half-duplex voice communication in areas of cab-to-cab, car-to-cab, cab-to-car. Amplifying, receiving and switching device contains: the pulsed DC/DC converters (2), inputs of which are connected to a DC power source (3); tripping device (4); power amplifier (5); resistor (6); high frequency filter (7 ); the voltage amplifier (8) connected to the loadspeaker (9) of driver's cab; three controle keys (10, 11 and 12); manipulator (13); mixer (14); OR-element (15); AND-element (16); NO-element (17). The communication system and public address system contains: the amplifying and receiving-switching device (1) located at opposite ends of electric traction; amplifying-receiving-switching device (26) connected by a line alert (18), to which loadspeakers (19) are connected; the communications line (20), which is connected to passengers interphone (21).
