PURPOSE: A danger information transceiver system combined with a radar detector and an electronic compass is provided to prevent additional accidents by coping with an urgent and flexible dangerous situation on a road. CONSTITUTION: A transceiver part(100) comprises an antenna, an oscillator oscillating a signal through the antenna, a receiver(130) receiving the signal through the antenna, a duplexer connecting the oscillator and the receiver, and an operation switch of the oscillator. A radar detector(200) comprises a radar detection part(210) sensing a band of an electromagnetic wave generation source and an intensity of an electromagnetic wave and then warning it by receiving the electromagnetic wave and a radar signal, and an electronic compass(220) detecting a traveling direction of a vehicle by sensing a terrestrial magnetic field. A DA converter(310) connects the radar detector and the oscillator of the transceiver part. An AD converter(320) connects the radar detector and the receiver of the transceiver part. And a comparator(330) converts a signal inputted from the receiver of the transceiver part in the AD converter and then compares it with the direction sensed in the electronic compass. |
