PURPOSE: A vehicle fire detector with oneself checking function and using wavelength range sensing is provided to improve the reliability of the vehicle fire detection and to sense the combustion wavelength band of the vehicle combustion. CONSTITUTION: The IR sensor(130) and thermopile sensor(140) sense the generated wavelength band generated by burn of the car fuel. The ultraviolet sensor(150) is used to block the malfunction by the false alarm of the fire detection. The emitting device(160) and nichrome wire(170) are used to check the abnormality of the inferiority or no of the fire sensor and IR sensor and thermopile sensor through the check signal. The compare output circuit part(180) confirms the fire was generated in an inside-vehicle and compares the IR sensor, and the thermopile sensor and the sensing signal level outputted from the ultraviolet sensor. The compare output circuit part generates two fire detection output signals to distinguish between the fire stop material or the mass fire about the auto fire detection. |
