The electronic tag according to claim 2, wherein the temperature detecting module is a temperature sensor, the electronic tag further comprises a storage module, the storage module is connected to the control module, the storage module stores ID information and/or article information of the electronic tag, and the communication information includes the ID information and/or the article information.
8. The electronic tag according to claim 2, wherein the first antenna is used for transmitting the communication information to a refrigeration device, and/or a bluetooth gateway, and/or a mobile terminal.
9. An article positioning method for refrigeration equipment, which is characterized by comprising
Acquiring compartment temperature parameters corresponding to compartments of the refrigeration equipment;
acquiring label environment temperature information transmitted by an electronic label, wherein the electronic label is attached to an article stored in the refrigeration equipment and comprises a temperature detection module for detecting temperature;
determining the compartment position of the refrigeration equipment where the electronic tag is located according to the tag environment temperature and the compartment temperature parameter;
and acquiring article information corresponding to the electronic tag, and associating the article information with the room position.
10. The article positioning method for the refrigeration equipment as set forth in claim 9, wherein each time the tag environment temperature information transmitted by the electronic tag is acquired, the compartment position where the electronic tag is located is determined according to the latest tag environment temperature.
11. The article positioning method for a refrigerating apparatus as recited in claim 9, wherein said compartment temperature parameter is a preset parameter or a parameter obtained by detecting each of said compartment temperatures, and said compartment position is said compartment corresponding to said compartment temperature parameter including said tag ambient temperature.
12. The article positioning method for a refrigeration appliance according to claim 9,
before "determining the compartment location of the refrigeration equipment where the electronic tag is located according to the tag environment temperature and the compartment temperature parameter", the method further includes:
acquiring a limiting temperature, wherein the limiting temperature is greater than the maximum value of the compartment temperature parameter;
and if the label environment temperature is higher than the limit temperature, judging that the electronic label is positioned outside the refrigeration equipment, and deleting the label environment temperature information.
13. The article location method for a refrigeration appliance of claim 9, wherein the article information includes information of a suitable storage compartment to which the article corresponds, the method further comprising:
judging whether the compartment position corresponds to the suitable storage compartment or not;
and if not, outputting prompt information for moving the electronic tag attached article to the suitable storage room.
14. A computer-readable storage medium, on which a computer program is stored which, when being executed by a processor, carries out the steps of the method for locating an article for a refrigeration device of any one of claims 9 to 13.
15. A refrigeration device comprising a plurality of compartments, characterized in that the refrigeration device comprises a memory and a processor, the memory storing a computer program operable on the processor, when executing the computer program, performing the steps in the method for article location for a refrigeration device according to any of claims 9-13.
