PURPOSE: A method for dualizing communication of an automatic rainfall and water level warning device and a device thereof are provided to transmit a warning event to a control state through a VHF communication unit and transmit a warning event through a CDMA communication unit, thereby dually preventing a disaster. CONSTITUTION: A rainfall sensor(150) measures rainfall. A first transceiver(110) receives a standard call signal from a control station and transmits a warning event signal to the control station. When failure of warning event signal transmission of the first transceiver occurs a fixed number of times, a second transceiver(140) transmits a warning event signal. A controller or an RTU(Real Time Unit)(130) detects a warning event according to the measured rainfall. A switching unit selects one of the first and second transceivers by determination of the RTU. Antennas(180,181) transmit and receive signals of the first transceiver or the second transceiver.
