Background technology
During fuel (oil, coal gas, gas, natural gas and coal dust when) burning, flame can generate some strength ultraviolet light and
Infrared ray.Flame spectrum distribution situation when being burnt according to different fuel selects corresponding flame detector.The flame used at present
Detector is all based on the ultraviolet light gone out to Fire Radiation or infrared ray is detected to realize, after occurring due to flame, all
A large amount of infrared ray can be given off outward, many detection schemes are based on being detected to judge to the infrared ray that Fire Radiation goes out
Whether the generation of fire is had.
Existing flame detector is typically all the analog voltage signal and base exported using voltage comparator to sensor
Quasi- voltage is compared, and then exports comparison result, judges whether there is fiery generation.The reference voltage can generally connect a cunning
Dynamic rheostat, is changed the value of reference voltage by the change in resistance of resistance, the sensitivity of flame detector is adjusted with this, but
The program can not obtain accurate sensor output voltage value, and the data obtained precision is not high.
