The system of claim 8, wherein the temperature sensor is installed on the inner surface of the pot in at least two zones, the gas outlet is installed on the gas range in at least two zones, the zones of the temperature sensor are installed in one-to-one correspondence with the zones of the gas outlet, one proportional valve is installed in correspondence with the gas outlet of one zone,

the temperature sensor is specifically used for obtaining regional temperature information of different regions in the cooker to obtain measured temperature information when the gas stove is started to heat the cooker;

the controller is also used for comparing the concentric circle temperature information of different concentric circles with the set temperature information to generate instruction information of the proportional valve corresponding to each concentric circle;

or the like, or, alternatively,

the controller is further used for comparing the concentric circle temperature information of the adjacent concentric circles and generating the instruction information of the proportional valve corresponding to each concentric circle.
