As shown in fig. 1 and 2, the refrigerator provided by the embodiment of the application is provided with at least two storage chambers, such as a freezing chamber, a refrigerating chamber, a temperature changing chamber, a fresh keeping chamber and the like, in the interior of the refrigerator. Each storage compartment may have a plurality of independent 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 the storage compartment. Specifically, the identification information of the RFID tag, such as tag codes written in the RFID tag, is obtained, and the corresponding relation between the identification information of the RFID tag and the appointed food material information is established, so that the association between the RFID tag and the food material is realized; placing the food material into a refrigerator after the RFID tag is attached to the food material, wherein the refrigerator can acquire the identification information of the RFID tag by detecting the signal of the RFID tag; under the condition that the identification information is acquired, the food material information corresponding to the RFID tags can be determined through the association relation between the identification information of the RFID tags and the food material information, a user interface for displaying the food materials is generated according to the food material information corresponding to each RFID tag in the refrigerator, so that a user can acquire the food materials in the refrigerator through the user interface, and management operation can be performed on the food materials through operating the user interface.

In some embodiments, RFID detector 380 includes an RFID detection module disposed within each storage compartment for transmitting wireless signals within the respective storage compartment and receiving signals from RFID tags within the storage compartment to obtain identification information for the RFID tags.

In some embodiments, the RFID detection module may be specifically an antenna. The power of the antennas disposed in the different storage compartments may be different. And moreover, the power of the antenna of each storage room can ensure that the antenna can identify food materials contained in the room of the antenna, so that the false identification rate can be increased when the power is too high, and the food materials not contained in the room of the antenna can be identified when the power is too low. In a specific implementation, the power of the antenna may be determined in advance according to the space size of each storage chamber, and the power of each antenna may be set in the refrigerator, the larger the space, the larger the power.

In some embodiments, a controller 320 is coupled to each RFID detection module to control the RFID detection module to identify the signal of the RFID tag within the storage compartment.

In some embodiments, the controller is configured to: and drawing a user interface according to food material information corresponding to each RFID tag 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 the form of food material icons, pictures and texts and the like as many as possible. In addition, functionality controls, such as RFID tag identification controls, food addition controls, and the like, may also 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, one food material display area can correspond to one storage room, so that the food materials in the same storage room can be intensively displayed in the same food material display area, and a user can intuitively acquire which specific storage room 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 is used for representing a corresponding food material, and the food material control may be formed by one or more interface elements such as a food material icon, a food material name, a freshness identifier of the food material, and the like, wherein 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 placement time, the remaining shelf life, and the like of the food material. Functional controls in the food material management interface include, but are not limited to, controls for triggering RFID tag identification, controls for adding food material information, controls for displaying recipe information, and the like.

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 judged, namely, the storage room where the food material identified by the RFID tag is located cannot be automatically acquired, for example, the RFID tags in other storage rooms can be identified by the antenna in the refrigerating room, and further intelligent partition management on the food material cannot be realized, so that user experience is affected.

In some embodiments, if a new RFID tag is detected to appear in the refrigerator, a food control corresponding to the food identified by the new RFID tag is displayed in a designated area in the food management interface, and a user selects the food to be partitioned and a corresponding storage room by operating the designated area, so that intelligent partition management of the new food is realized.

Fig. 4 is a user interface, specifically an exemplary food material management interface, according to an exemplary embodiment of the present application. Referring to fig. 4, the food management interface is divided into left and right display areas; the left side area comprises RFID tag identification controls and food material display areas corresponding to the food material categories, such as fruits and vegetables, and each food material display area displays food material icons and food material names of the corresponding categories; the right side 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, where the custom area is used to display newly added food materials in the refrigerator that are not classified by the user in a partition. In the food material management interface shown in fig. 4, the number of the food materials identified by the RFID tag in the refrigerator is displayed.

When the display screen displays the food material management interface shown in fig. 4, the user can click the custom region to trigger the operation flow of classifying the food materials in the custom region in a partitioning manner.

Illustratively, in response to a user clicking on the custom region, a virtual storage interface is displayed as shown in FIG. 5, in which the food material information to be stored in the partition and the storage compartment options that may be allocated, along with associated functionality controls, such as "determine", "cancel", and so forth, 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, although the partition management of the food materials can be realized, the 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 capable of further improving the intelligent management capability of the refrigerator and improving 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 each RFID tag is classified into a first type of RFID tag and a second type of RFID tag according to whether the RFID tag is currently placed in the storage compartment or has been moved out of the storage compartment, wherein the first type of RFID tag refers to an RFID tag currently placed in the storage compartment and the second type of RFID tag refers to an RFID tag that has been currently moved out of the storage compartment.

In some embodiments, whether the RFID tag is a first type of RFID tag or a second type of RFID tag is determined based on a third attribute value of the RFID tag, that is, the first type of RFID tag is different from the third attribute value of the second type of 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 above 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 labels of the first type RFID tag and the second type RFID tag, for example, the status of the first type RFID tag is a storing status, the status of the second type RFID tag is a moving-out status, or may be 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 storage compartment that was previously associated with the RFID tag. For example, if the first attribute value of a certain RFID tag=0, it is indicated that the RFID tag has been associated with the refrigerator in advance, if the first attribute value of a certain RFID tag=1, it is indicated that the RFID tag has been associated with the freezer in advance … …, when the user uses the RFID tag to identify the food material, the user should select the corresponding RFID tag according to the refrigerator in which the food material should be placed, for example, since "apple" is supposed to be placed in the refrigerator, the user should select the RFID tag associated with the refrigerator in advance to identify "apple". It should be noted that, in order to facilitate the user to distinguish the storage room to which each RFID tag is associated, RFID tags associated with different storage rooms may be artificially produced in different colors, for example, a red RFID tag may be used as an RFID tag associated with a refrigerating room, a green RFID tag may be used as an RFID tag associated with a freezing room, and so on.

Based on this, the controller of the refrigerator is configured to: acquiring food material information corresponding to a first type of RFID tag from local data to obtain a first information set; 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 which are equivalent to the storage chambers in number, and each food material display area is provided with food material controls generated according to the food material information, wherein the food material controls corresponding to the RFID tags with the same first attribute value 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 the locally stored RFID tags; and acquiring food material information corresponding to the first type RFID tag according to the identification information of the first type RFID tag to obtain a first information set.

In the above embodiment, since the first attribute value of the RFID tag characterizes the storage room associated with the RFID tag, the food controls corresponding to the RFID tag with the same first attribute value are displayed in the same food display area, and the food controls corresponding to the RFID tag with different first attribute values are displayed in different food display areas, that is, the food controls of the food in the same storage room are displayed in the same food display area, so that an automatic partitioning process of the food is realized, and a user does not need to operate each newly added food in the refrigerator one by one, thereby improving the intelligent management degree of the refrigerator on the food, and improving the user experience.

Fig. 6 is a schematic diagram of a food material management interface according to the present application, and as shown in fig. 6, the food material management interface includes three food material display areas, namely, a food material display area corresponding to a refrigerating chamber, a food material display area corresponding to a wide greenhouse, and a food material display area corresponding to a cold greenhouse, where 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 the 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, 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 may be parsed 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 a 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-class RFID tag, acquiring a tag code of the first-class RFID tag from the local data; intercepting a first code segment for writing a first attribute value of the first type RFID tag from the tag code to obtain the first attribute value of the first type RFID tag; determining a target storage room associated with the first type of RFID tag 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 tag in the target food material display area.

In some embodiments, each food material control includes an explicit tag identifier in addition to a food material icon, a food material name, and a freshness identifier, to prompt a user which food materials corresponding to the food material control are food materials identified by an RFID tag.

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

Fig. 7 is a schematic diagram 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 a dominant label identifier 704. Fig. 8 is a schematic diagram of another food material control shown in an exemplary embodiment of the present application, unlike the food material control shown in fig. 7, the overt tag label in fig. 7 is different in color from the overt tag label in fig. 8.

As previously described, to facilitate a user in distinguishing between the compartments to which each RFID tag is associated, RFID tag entities associated with different compartments may be artificially produced or marked with different colors. Based on this, in some embodiments, the dominant label identification of the RFID tag is drawn to the same color as the color of its tag entity, and the dominant label identifications of the food material controls in the same food material display zone are drawn to the same color, and the dominant label identifications of the food material controls in different food material display zones are drawn to different colors, so that a user may select the RFID tag associated with a given storage compartment to identify food materials in the given storage compartment according to the color of the dominant label identifications of the food material controls in the food material display zone to which the given storage compartment corresponds.

In some embodiments, each RFID tag further has a second attribute value, where the second attribute value corresponds to a color value in advance, to characterize a color of an explicit tag identifier corresponding to an explicit tag identifier, that is, an explicit tag identifier of a food control corresponding to an RFID tag having the same second attribute value is drawn in the same color, and an explicit tag identifier of a food control corresponding to an RFID tag having a different second attribute value is drawn in a different color. For example, according to the pre-established correspondence between the second attribute value and the color value, if the second attribute value=0 of a certain RFID tag, the color of the dominant tag identification characterizing the RFID tag should be drawn as red, if the second attribute value=1 of the RFID tag, the color of the dominant tag identification characterizing the RFID tag should be drawn as green, and so on.

In some embodiments, the second attribute value characterizes the first attribute value of the RFID tag of the first color characterizes the refrigerator, the second attribute value characterizes the first attribute value of the RFID tag of the second color characterizes the freezer, and the second attribute value characterizes the first attribute value of the RFID tag of the third color characterizes the temperature changing chamber, so that in the displayed food material management interface, the dominant label identifier of the food material control in the food material display area corresponding to the refrigerator is displayed as the first color, the dominant label identifier of the food material control in the food material display area corresponding to the freezer is displayed as the second color, and the dominant label identifier of the food material control in the food material display area corresponding to the temperature changing chamber is displayed as 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.

In other embodiments, the second attribute value of the RFID tag is specifically a code segment of the 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 second attribute value may be parsed according to a composition rule of the tag code, so as to obtain the second attribute value of the RFID tag.

Illustratively, assuming that the 26 th bit of the 28-bit tag code is used to write a second attribute value of the RFID tag, the second attribute value of the RFID tag is "5" as known from tag code "0123456789012345678901234567".
