Control method and device of electric pressure cooking utensil and electric pressure cooking utensil

The embodiment of the invention provides a control method and device of an electric pressure cooking utensil and the electric pressure cooking utensil. The method comprises the following steps: acquiring environment air pressure, wherein the environment air pressure is air pressure of an environment where the electric pressure cooking utensil is located; obtaining cooking air pressure; determining at least one control temperature based on the ambient pressure and the cooking pressure; and according to the at least one control temperature, the air pressure in the pot of the electric pressure cooking utensil is kept within a set air pressure range, and the set air pressure range is a range with the cooking air pressure as the midpoint and the difference value between the boundary value and the cooking air pressure is smaller than or equal to a preset difference value. According to the technical scheme provided by the embodiment of the invention, the temperature monitoring is performed according to the at least
