In overall process, auxiliary detection is only made in temperature sensor, and such as the lid that boils, addition food materials and water cause the change of temperature,
The temperature (at this time heat propagation settles out, it is important to pre-anti-dry) being nearly completed with culinary art.
Detailed process is: 1, start to put food, and culinary art helps material (such as salt, oil, beans), water etc..Sound sensor module is without effectively
Output (only environment noise), temperature sensor output room temperature.Trigger switch, beginning of boiling.
2, being heated to a certain degree, sound transducer 21 has the heated voice output caused of food and liquid, due to
Being heated uneven, sound is more sparse, the environment noise relatively started, and in the output of its frequency spectrum, some frequency range output amplitude occurs
Add, but the frequency occurred is less.Need to continue heating, need not intervene.
3, food is heated to a certain degree, and the heated voice output caused of food and liquid is bigger, and sound passes
Sensor 21 exports, and through frequency spectrum transformational analysis, occurs that some frequency range amplitude continues to increase, and the frequency that these states occur is relatively
Greatly, and frequently, important audio spectrum change point occurs in that, at this moment needs operator certainly to sentence or intelligent terminal points out very important person
Hands intervenes (such as stirring, add water, add food materials condiment etc.), allows heat transfer evenly, and taste is more pleasant.
4, when the acoustical signal of sound transducer 21 output, exporting through spectrum analysis, some bin magnitudes is not further added by, but
