s4: collecting gas flow by using a gas flow meter, transmitting the gas flow to a controller, judging whether cooking is finished or not, if so, entering step S5, and if not, continuing to execute step S4;
s5: acquiring mobile information by using an infrared sensor, judging whether the front of a cooking bench is unattended or not, if so, sending out a voice warning by using a loudspeaker, sending warning information to a mobile terminal by using a wireless transmission module, and entering a step S6, otherwise, directly entering a step S6;
s6: and controlling all the second electromagnetic valves to be closed by using the controller, and finishing heat supply.
6. A heat supplying method of controlling a safety gas range based on heat as claimed in claim 5, wherein the calculation formula of the total heat threshold at step S1 is:
in the formula, QGeneral assemblyA total heat threshold required for cooking; q'iThe heat required for cooking stage i; qiProviding heat for a second air inlet pipe of a cooking stage i, wherein i is a cooking stage variable, i is 1,2, N is the number of required cooking stages, and α is a heat transfer coefficient;
the calculation formula of the total heat supply time threshold value is as follows:
Tgeneral assembly＝t1+t2+...+tN
In the formula, TGeneral assemblyIs a total heating time threshold; t is tiHeating time for a cooking stage i, i being a cooking stage variable, i being 1, 2. N is the number of cooking stages required.
7. A heat supplying method of controlling a safety gas range based on heat according to claim 5, wherein in the step S4, the judgment formula of the cooking end is:
of formula (II) to Q'General assemblyProviding heat for the current gas stove; qGeneral assemblyIs the total heat threshold; t current system time; t isGeneral assemblyIs a total heating time threshold; i is a cooking stage variable; n is the number of cooking stages required;
if at least one of the conditions is satisfied, the output is the end of cooking.
8. The heat supply method of the heat-based control safety gas range according to claim 5, wherein in the automatic heat supply process, the voice recognition module recognizes the voice command to stop the cooking task or skip the current cooking stage;
the manual heat supply method is characterized in that the first electromagnetic valve is opened or closed by using the manual switch part, the first air inlet pipe is used for supplying air, manual heat supply is carried out, and when the opening signal of the first electromagnetic valve is detected, all the second electromagnetic valves are controlled to be closed.
