Method of automatically opening and closing door body of refrigeration or heating box by recognizing user identity

A method of automatically opening and closing a door body of a refrigeration or heating box by recognizing a user identity, comprising:

• S1, obtaining, by a logic control unit of the refrigeration or heating box, user identity information based on information from an external sensor;
• S2, recognizing and determining, by the logic control unit, the user identity information to obtain a recognition result;
• in response to the recognition result being that the user identity information is not authorized, displaying, by a display screen of the refrigeration or heating box, an error prompt;
• and
• S3, in response to the recognition result being that the user identity information is authorized, opening, by a control circuit system of the refrigeration or heating box, the door body;
• wherein the refrigeration or heating box further comprises a heat-absorbing energy-conversion electric-energy module system and an energy storage module system connected to the logic control unit;
• wherein the refrigeration or heating box further comprises a refrigeration control system connected to the logic control unit, the refrigeration control system having a control system connected to a compressor and a solenoid valve, a semiconductor refrigeration chip control system, a chemical agent control system, and a physical heat converter control system;
• wherein the refrigeration or heating box further comprises a heating control system connected to the logic control unit, the heating control system having a semiconductor refrigeration sheet control system, a cold simulator converter control system, a heating tungsten filament control system, a graphene and carbide control system, and a chemical agent and a physicality heater.
