DANGER SIGNAL RECEIVING DEVICE USING CAR AUDIO

摘要

PURPOSE: A danger signal receiving device using a car audio is provided to minimize damages on the human lives and the other things due to an accident by informing a driver of a dangerous area on a road during a travel. CONSTITUTION: A transmitter(100) installed in a dangerous area outputs signals of a predetermined frequency and the signals are received in a receiving unit(210) of a receiver(200) mounted on a car audio. A detector(220) converts the signals to a reference logic value and a control unit(230) outputs a control signal corresponding to the logic value. The control signal is amplified by an amplifying unit(240) and a speaker(250) receives the amplified control signal and generates a warning sound to have a driver recognize the appearance of a dangerous area. A display unit(260) displays the appearance of the dangerous area with characters.
