In the refrigerating system, four parts of a compressor, a condenser, an evaporator and a capillary tube restrictor are mainly formed, and a closed circulating system is formed. Wherein the evaporator is installed at the upper part of the refrigerator, and other components are installed at the back of the refrigerator. The refrigerating system is charged with a refrigerant such as "freon 12(CF2Cl2, international symbol R12)" as a refrigerant. R12 is vaporized from low-pressure liquid to gas in evaporator to absorb heat in refrigerator and lower the temp in refrigerator. The R12 changed into a gaseous state is sucked by the compressor, compressed into a high-temperature and high-pressure gas by the compressor work, and discharged into the condenser. In the condenser, R12 continuously gives off heat to the surrounding space and gradually condenses into liquid. The high-pressure liquid must flow through the capillary tube, and then the liquid can slowly flow into the evaporator after throttling and reducing pressure, and is continuously vaporized in the evaporator, and absorbs heat and reduces temperature. In this way, the refrigerator uses electric energy to do work, and by means of the change of the state of refrigerant R12, the heat around the evaporator in the refrigerator is transferred to the refrigerator and then discharged from the refrigerator in the condenser, and the operation is repeated and continuously circulated to achieve the purpose of refrigeration.

And prompting a user that a plurality of labels exist in the accessory of the scanning area, and judging according to the instruction content. If the tag reading command is issued, step S207 is executed; if the tag command is a define tag command, go to step S208.
Step S207, a tag instruction is read.
The refrigerator interface displays the read contents of the N tags, and a user can view more detailed contents when selecting one tag.
Step S208, selecting the mode for defining the label instruction.
The user sends a definition instruction to select a mode of defining the tags, wherein the definition instruction can be a single-tag definition instruction or a multi-tag definition instruction, the single-tag definition instruction is an instruction for defining the selected single tag, and the multi-tag definition instruction is an instruction for defining all tags according to the same definition. If yes, go to step S209; if the multi-tag definition is determined, step S210 is executed.
In step S209, a single tag is defined.
And displaying the read N label contents on the refrigerator interface, and selecting one label by a user for label definition.
Step S210, defining a multi-label.
The scanned N tags are defined as the same food material name.
Through above technical scheme, trigger the work of door body antenna, the number N of the dish point label in T time, judge the value of N, the suggestion user scans the district annex and does not have the label, it is exactly that the user carries out the label of operation to lock this label, judge instruction content, read the label instruction, select the mode of defining the label instruction, define the single label, define many labels, thereby make a plurality of RFID labels that the refrigerator can accurately handle and scan simultaneously, and can read or define the operation of RFID label to the multiple food material that scans, very big promotion user experience.
