As shown in fig. 1 and fig. 2, in the refrigerator provided in the embodiment of the present application, at least two storage compartments, such as a freezing compartment, a refrigerating compartment, a temperature changing compartment, and/or a fresh food compartment, are provided inside a cabinet. Each storage compartment may have a plurality of separate storage spaces therein, such as drawer compartments.

In some embodiments, to enable intelligent management of food materials, RFID tags are used to identify food materials in a storage room. Specifically, identification information of the RFID tag, such as a tag code written in the RFID tag, is obtained, and a corresponding relationship between the identification information of the RFID tag and the specified food material information is established, so that association between the RFID tag and the food material is realized; after the RFID tag is attached to the food material, the food material is placed into a refrigerator, and the refrigerator can acquire identification information of the RFID tag by detecting a signal of the RFID tag; under the condition of acquiring the identification information, the food material information corresponding to the RFID tags can be determined through the pre-established association relationship between the identification information of the RFID tags and the food material information, and a user interface for displaying food materials is generated according to the food material information corresponding to each RFID tag in the refrigerator, so that a user can know the food materials in the refrigerator through the user interface and can perform management operation on the food materials by operating the user interface.

In some embodiments, the RFID detector 380 includes an RFID detection module disposed within each storage compartment for transmitting a wireless signal at the corresponding storage compartment and receiving a signal of an RFID tag within the storage compartment to obtain identification information of the RFID tag.

In some embodiments, the RFID detection module may be specifically an antenna. The power of the antennas provided in different storage compartments may be different. And the power of the antenna of each storage room can ensure that the antenna can identify the food materials in the self room, thereby avoiding that the error identification rate is increased when the power is too high and the food materials in the incomplete self room can be identified when the power is too low. In a specific implementation, the power of the antenna can be determined in advance according to the space size of each storage room, and the power of each antenna is set in the refrigerator, and the larger the space is, the larger the power is.

In some embodiments, a controller 320 is connected to each RFID detection module to control the RFID detection module to recognize signals of RFID tags in the storage compartment.

In some embodiments, the controller is configured to: and drawing a user interface according to the food material information corresponding to each RFID label in the storage room, and displaying the user interface on a display screen, such as a food material management interface. In the food material management interface, food materials in the refrigerator are displayed in a best mode in the forms of food material icons, pictures and texts and the like. In addition, functional controls, such as an RFID tag identification control, a food material addition control, and the like, can be drawn in the user interface.

In order to realize intelligent partition management of food materials in the refrigerator, the food material management interface can comprise a plurality of food material display areas and functional controls, and one food material display area can correspond to one storage chamber, so that the food materials in the same storage chamber can be displayed in the same food material display area in a centralized manner, and therefore a user can intuitively acquire which specific storage chamber stores which food materials.

In some embodiments, a food material control is generated in the food material management interface according to the food material information and used for representing a corresponding food material, and the food material control may be composed of one or more interface elements such as a food material icon, a food material name, and a freshness identifier of the food material, where the food material icon may be generated according to a pictographic picture of the food material, and the freshness identifier of the food material is used for showing the putting time, the remaining shelf life, and the like of the food material. The functional controls in the food material management interface include, but are not limited to, a control for triggering identification of the RFID tag, a control for adding food material information, and a control for displaying menu information, etc.

In practical application, because the detection range of the RFID detection module is very large, the storage position of each RFID tag cannot be accurately determined, that is, the storage room where the food material identified by the RFID tag is located cannot be automatically acquired, for example, the RFID tag of other storage rooms may be identified by an antenna in the freezing room, so that intelligent partition management of the food material cannot be realized, and user experience is affected.

In some embodiments, if it is detected that a newly added RFID tag occurs in the refrigerator, the food material control corresponding to the food material identified by the newly added RFID tag is displayed in a designated area in the food material management interface, and a user selects a food material to be partitioned and a corresponding storage chamber by operating the designated area, thereby implementing intelligent partition management of the newly added food material.

Fig. 4 is a user interface according to an exemplary embodiment of the present application, which is specifically an exemplary food material management interface. Referring to fig. 4, the food material management interface is divided into two display areas, left and right; the left area comprises an RFID tag identification control and food material display areas corresponding to food material categories, such as fruits and vegetables, wherein food material icons and food material names of the corresponding categories are displayed in each food material display area; the right area comprises recommended menu controls and food material display areas corresponding to the storage chambers, such as a refrigerating chamber, a temperature changing chamber, a freezing chamber and the like, and corresponding food material icons and food material names are displayed in each food material display area. In addition, the right area of the food material management interface shown in fig. 4 further includes a custom area, and the custom area is used for displaying new food materials which are not classified by the user in the refrigerator. In the food material management interface shown in fig. 4, the number of food materials identified by the RFID tag in the refrigerator is displayed.

When the food material management interface shown in fig. 4 is displayed on the display screen, the user can click the user-defined area to trigger the partition classification operation flow of the food material in the user-defined area.

Illustratively, in response to the user clicking on the custom area, a virtual storage interface as shown in fig. 5 is displayed, in which the food material information to be stored in the partition and the storage room options that can be allocated, and related function controls, such as "determine", "cancel", and the like, are displayed. And the user realizes the partition storage of the food materials in the user-defined area by operating the control in the virtual storage interface.

According to the embodiment, partition management of the food materials can be achieved, but a user needs to operate each newly added food material in the refrigerator one by one, the intelligent management degree of the refrigerator on the food materials is low, and the user experience is poor.

Embodiments that can further improve the intelligent management capability of the refrigerator and improve the user experience will be described in detail below.

In some embodiments, the local data includes identification information of a plurality of RFID tags and corresponding food material information, and the RFID tags are classified into a first type RFID tag and a second type RFID tag according to whether each RFID tag is currently placed in the storage room or moved out of the storage room, wherein the first type RFID tag refers to an RFID tag currently placed in the storage room, and the second type RFID tag refers to an RFID tag currently moved out of the storage room.

In some embodiments, whether the RFID tag is the first type RFID tag or the second type RFID tag is determined according to the third attribute value of the RFID tag, that is, the third attribute value of the first type RFID tag is different from that of the second type RFID tag. Illustratively, the third attribute value of the first type of RFID tag is 0, and the third attribute value of the second type of RFID tag is 1.

It should be noted that the third attribute value is used to distinguish the first type RFID tag from the second type RFID tag, and the specific form of the third attribute value is not limited in the present application, and may be different status marks possessed by the first type RFID tag and the second type RFID tag, for example, the marked status of the first type RFID tag is a storage status, and the marked status of the second type RFID tag is a removal status, or different storage paths corresponding to the first type RFID tag and the second type RFID tag, for example, the identification information of the first type RFID tag is stored in the first table, the identification information of the second type RFID tag is stored in the second table, and so on.

In addition, each RFID tag has a first attribute value that characterizes a repository with which the RFID tag was previously associated. For example, if the first attribute value of a certain RFID tag is 0, the characterization is that the RFID tag has been associated with the refrigerating compartment in advance, and if the first attribute value of a certain RFID tag is 1, the characterization is that the RFID tag has been associated with the freezing compartment in advance … …, when the user uses the RFID tag to identify food, the user should select the corresponding RFID tag according to the storage compartment into which the food should be placed, for example, the user should select the RFID tag associated with the refrigerating compartment in advance to identify "apple" because "apple" should be placed into the refrigerating compartment. It should be noted that to facilitate the user in distinguishing the storage compartments to which each RFID tag is associated, the RFID tags associated with different storage compartments may be artificially produced in different colors, for example, a red RFID tag may be used as the RFID tag associated with the refrigerator compartment, a green RFID tag may be used as the RFID tag associated with the freezer compartment, and so on.

Based on this, the controller of the refrigerator is configured to: food material information corresponding to the first type of RFID tags is obtained from local data, and a first information set is obtained; and then displaying a food material management interface according to the first information set, wherein the food material management interface comprises food material display areas with the number equivalent to that of the storage chambers, food material controls generated according to the food material information are displayed in each food material display area, and the food material controls corresponding to the RFID tags with the same first attribute values are displayed in the same food material display area.

In a specific implementation, the controller may determine the first type of RFID tag according to the third attribute values of all locally stored RFID tags; and acquiring food material information corresponding to the first type of RFID labels according to the identification information of the first type of RFID labels to obtain a first information set.

In the above embodiment, because the first attribute value of the RFID tag represents the storage chamber to which the RFID tag is associated, the food material controls corresponding to the RFID tags having the same first attribute value are displayed in the same food material display area, and the food material controls corresponding to the RFID tags having different first attribute values are displayed in different food material display areas, that is, the food material controls of the food material in the same storage chamber are displayed in the same food material display area, so that an automatic food material partitioning process is realized, and a user does not need to operate each newly added food material in the refrigerator one by one, so that the intelligent management degree of the refrigerator on the food materials is improved, and the user experience is improved.

Fig. 6 is a food material management interface exemplarily shown in the present application, and as shown in fig. 6, the food material management interface includes three food material display areas, which are a food material display area corresponding to a refrigerating chamber, a food material display area corresponding to a wide-temperature chamber, and a food material display area corresponding to a cold-temperature chamber, respectively, and each food material display area displays a food material control corresponding to a food material in a corresponding storage chamber.

In some embodiments, the first attribute value of the RFID tag may be an attribute value stored in local data corresponding to the identification information of the RFID tag, and the first attribute value of the RFID tag may be obtained according to the identification information of the RFID tag.

In other embodiments, the first attribute value of the RFID tag is specifically a code segment of a tag code of the RFID tag, and the tag code of the RFID tag may be identified by the RFID detection module, and the code segment written with the first attribute value is analyzed according to a composition rule of the tag code, so as to obtain the first attribute value of the RFID tag.

Illustratively, assuming that the 25 th bit of the 28-bit tag code is used to write the first attribute value of the RFID tag, the first attribute value of the RFID tag is "4" as known from the tag code "0123456789012345678901234567".

Based on this, the controller of the refrigerator is further configured to: for each acquired first type RFID tag, acquiring a tag code of the first type RFID tag from local data; intercepting a first code segment used for writing a first attribute value of a first type of RFID label from a label code to obtain the first attribute value of the first type of RFID label; determining a target storeroom associated with the first type of RFID label according to the first attribute value; determining a target food material display area corresponding to the target storage room; and drawing the food material control corresponding to the first type of RFID label in the target food material display area.

In some embodiments, each food material control comprises an explicit tag identification in addition to the food material icon, the food material name, and the freshness identification, so as to prompt a user which food material controls correspond to food materials identified by the RFID tag.

In some embodiments, the dominant tag identifications of the food material controls in the same food material display area are drawn in the same color, and the dominant tag identifications of the food material controls in different food material display areas are drawn in different colors. Therefore, the user can judge the storage room where the food material is located according to the color of the dominant label mark.

Fig. 7 is a schematic view of a food material control according to an exemplary embodiment of the present application, and as shown in fig. 7, the food material control includes a food material icon 701, a food material name 702, a freshness identifier 703, and an explicit tag identifier 704. Fig. 8 is a schematic view of another food material control shown in an exemplary embodiment of the present application, and different from the food material control shown in fig. 7, colors of the dominant tag in fig. 7 are different from colors of the dominant tag in fig. 8.

As previously mentioned, to facilitate the user in distinguishing the repository with which each RFID tag is associated, the RFID tag entities associated with different repositories may be artificially produced or labeled with different colors. Based on this, in some embodiments, the dominant label identifier of the RFID label is drawn to the same color as the color of the label entity, the dominant label identifier of the food material control in the same food material display area is drawn to the same color, and the dominant label identifiers of the food material controls in different food material display areas are drawn to different colors, so that the user can select the RFID label associated with the designated storage room to identify the food material in the designated storage room according to the color of the dominant label identifier of the food material control in the food material display area corresponding to the designated storage room.

In some embodiments, each RFID tag further has a second attribute value, where the second attribute value is pre-corresponding to the color value and is used to represent a color of the dominant tag corresponding to the dominant tag identifier, that is, the dominant tag identifiers of the food controls corresponding to the RFID tags having the same second attribute value are rendered in the same color, and the dominant tag identifiers of the food controls corresponding to the RFID tags having different second attribute values are rendered in different colors. For example, according to the pre-established correspondence relationship between the second attribute value and the color value, if the second attribute value of a certain RFID tag is equal to 0, the color of the dominant tag identifier representing the RFID tag should be drawn as red, and if the second attribute value of the RFID tag is equal to 1, the color of the dominant tag identifier representing the RFID tag should be drawn as green, and so on.

In some embodiments, the second attribute value represents the refrigerating chamber, the first attribute value represents the freezing chamber, and the second attribute value represents the temperature-changing chamber, so that in the displayed food material management interface, the dominant tag identifier of the food material control in the food material display area corresponding to the refrigerating chamber is displayed in the first color, the dominant tag identifier of the food material control in the food material display area corresponding to the freezing chamber is displayed in the second color, and the dominant tag identifier of the food material control in the food material display area corresponding to the temperature-changing chamber is displayed in the third color.

In some embodiments, the second attribute value of the RFID tag may be an attribute value stored in the local data corresponding to the identification information of the RFID tag, and the second attribute value of the RFID tag may be obtained according to the identification information of the RFID tag.
