APPARATUS FOR GUIDING RAILROAD STATION USING RF COMMUNICATION

摘要

PURPOSE: An apparatus for guiding railroad station using RF communication is provided to resolve a problem for renewing a content of a tape or an audio IC when adding or changing railroad stations by receiving railroad station guiding information as an RF communication from each railroad station and performing a railroad station guiding broadcasting when a train is entranced in a railroad station. CONSTITUTION: A first RF antenna(ANTa) transmits guiding information of a corresponding railroad station and a next railroad station as a first frequency for providing guiding information of the corresponding railroad station and the next railroad station to a train conveyed in a first direction. A second RF antenna(ANTb) transmits guiding information of a corresponding railroad station and a next railroad station as a second frequency for providing guiding information of the corresponding railroad station and the next railroad station to a train conveyed in a second direction. A first RF transmitting unit(14) modulates guiding information of the corresponding railroad station and the next railroad station using the first frequency and outputs the modulate signal to the first RF antenna(ANTa). A second RF transmitting unit(15) modulates guiding information of the corresponding railroad station and the next railroad station using the second frequency and outputs the modulate signal to the second RF antenna(ANTb).
