One of：
Mode one, determine that abnormal color occurs in the combustion flame of gas-cooker release；
Liquefied petroleum gas or the normal flame of Natural Gas stove are light blue color, and flare internal flame is clear, height about 20mm, have
Slight noise, firepower are vigorous.When primary air deficiency, because hydrocarbon is under high temperature, anoxia condition, generation is decomposed
Hard carbon, it is dispersed in as mist in gas.Bright faint yellow flame (i.e. abnormal face can be presented during these carbon grain combustions
Color), thus it is referred to as Huang Yan, its producing cause generally includes following several situations：
Situation one, kitchen range valve opening are excessive, and combustion gas is excessive, lack of air, it may appear that Huang Huo；

Mode two, determine that the combustion flame of gas-cooker release is in from flame state.
In flame normal combustion, the air velocity that fire hole is left in combustion gas should be adapted with burning velocity, on fire hole
Just there is a nattier blue flame, but when gas injection is more than burning velocity from the speed of fire hole, flame is just unable to maintain that
It is stable, and fire hole certain distance can be left and burnt away, vibration is presented in flame at this moment, and such a phenomenon is referred to as from flame.And make
Common cause into such a phenomenon is：Speed air flow in kitchen is too fast, therefore, it is necessary to reminds user to turn down lampblack absorber
Exhausting dynamics and/or reduce window draught area.
In image recognition processes, firstly, it is necessary to be pre-processed to the flame image collected, (it includes：Image is gone
Processing of making an uproar is handled with image sharpening) so that the image after processing seems smooth and clear.Secondly, flame image is carried out
Dividing processing, detailed process can include：Choose a frame rest image (such as：Flame normal combustion image) it is used as Background
Picture, frame image sequence is extracted according still further to certain sampling rate, the picture in background image is subtracted by the pixel in current frame image
This difference algorithm of element obtains error image, and then error image is split to obtain bianry image according to predetermined threshold value.
Again, area of flame variation characteristic, flame profile feature, flame flicking frequecy characteristic are extracted from the image after dividing processing.
Then, neutral net is built, the area of flame variation characteristic extracted, flame profile feature, flame flicking frequecy characteristic are made
For input layer element, then the degree of membership of each feature is determined with the membership function of Gauss model, entered by repetition training
And obvious vibration is presented with the presence or absence of part flame region in output layer judges a two field picture.
Alternatively, can it is determined that the mess kit generation being placed in cooking process on gas-cooker is abnormal in step S22
With including one of in the following manner：
