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.

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 material information corresponding to the RFID tag in the refrigerator is displayed in 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.

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 RFID tag identification controls and food material display areas corresponding to food material categories, such as fruits and vegetables, wherein the food material controls corresponding to the food materials 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 the food material controls corresponding to the food materials in the corresponding storage chambers are displayed in each food material display area.

It should be noted that the controller generates a food material control in the food material management interface according to the food material information corresponding to each RFID tag in the storage room, so as to represent the corresponding food material. As can be seen from fig. 4, 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 a food material, where the food material icon may be generated according to an pictographic picture of the food material, and the freshness identifier of the food material is used to show the input time, the remaining shelf life, and the like of the food material.

In some embodiments, in the embodiments, the refrigerator controller determines the food material information corresponding to each RFID tag according to the identification information of each RFID tag and the correspondence between the pre-established identification information and the food material information. By pre-establishing the corresponding relation between the identification information of the RFID tag and the food material information, the virtual association of the RFID tag and the food material can be realized. The identification information of the RFID tag may be a tag code of the RFID tag identified by the detection module, or may be a code segment in the tag code.

For example, the correspondence relationship between the identification information of the RFID tag and the food material information established in advance may be shown as the following table:

RFID	food material information
		Identification 1	Apple and fruit
Identification 2	Cucumber and vegetable
		Identification 3	Pork and meat
……	……

In some embodiments, a correspondence table between the identification information of the RFID tag and the food material information is established on the refrigerator side and stored locally. Specifically, when the food material management interface is displayed on the display screen, a user can input an instruction for instructing to input food material information by operating the food material management interface, for example, the user clicks a food material information input control provided by the food material management interface to instruct to input the food material information; when the controller receives the instruction, starting to detect a signal of the RFID tag placed in the designated area to acquire identification information of the RFID tag, and displaying an editing interface for associating the RFID tag with food material information, wherein the acquired identification information of the RFID tag is displayed in the editing interface, and the editing interface is configured to receive the food material information input by a user and can comprise an input position for inputting the food material information; and after the controller receives the food material information input by the user on the editing interface, correspondingly storing the received food material information and the identification information, thereby completing and perfecting the establishment of the corresponding relation table of the identification information of the RFID label and the food material information.

For example, a user may click on an RFID tag identification control in the food material management interface shown in fig. 4 to input an instruction indicating to enter food material information. When the controller receives the instruction input by the user, in response to the instruction, a prompt (shown in fig. 5) for prompting the user to place the RFID tag in the sensing area is displayed on the upper layer of the food material management interface shown in fig. 4, and a signal for detecting the RFID tag placed in the sensing area is started to acquire the identification information of the RFID tag. And after the controller acquires the identification information of the RFID label, presenting an association interface containing the identification information on a display screen.

Fig. 6 is an editing interface shown in the present application according to an exemplary embodiment, and as shown in fig. 6, the associated interface displays identification information "20200005" of an RFID tag, an input position for inputting a name of a food material, an input position for inputting a category of the food material, and a "cancel" control and a "confirm" control.

In the embodiment, the identification information of the RFID tag is identified through the RFID module and displayed in the editing interface, and the user does not need to manually input the identification information, so that input errors are avoided, and user operation is saved. By establishing the corresponding relation between the RFID tag and the food material information, the virtual association between the RFID tag and the food material information is realized, and the corresponding relation between the RFID tag and the food material information can be modified, so that the same RFID tag sequentially corresponds to different food material information, and the use flexibility of the RFID tag is improved.

In practical application, the RFID tags that are put into use are taken out and put into the refrigerator for many times by the user, and for any RFID tag, when the RFID tag is put into the refrigerator again, the food material corresponding to the actual identifier thereof changes, for example, when a certain RFID tag is taken out, the food material identified by the RFID tag is "radish", when the RFID tag is put into the refrigerator again, the food material identified by the RFID tag is "apple", and since the food material control corresponding to the RFID tag displayed in the food material management interface is still the food material control generated according to the information such as "radish", confusion of the user is easily caused, and user experience is not facilitated.

In addition, if a plurality of identical food materials are stored in the refrigerator, according to the above embodiment, the plurality of identical food material controls are displayed in the food material management interface, and if a user takes out a first food material of the plurality of identical food materials from the refrigerator and puts the first food material into the refrigerator, the user cannot distinguish which of the plurality of identical food material controls in the food material management interface is the food material control corresponding to the first food material, which is not friendly to the user experience.

Embodiments that can solve the above problems 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 a first type RFID tag or a second type RFID tag is determined according to a second attribute value of the RFID tag, that is, the second attribute value of the first type RFID tag is different from that of the second type RFID tag. Illustratively, the second attribute value of the first type of RFID tag is 0, and the second attribute value of the second type of RFID tag is 1.

It should be noted that the second attribute value is used to distinguish the first type RFID tag from the second type RFID tag, and the specific form of the second 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 label has a first attribute value, and the first attribute value of the RFID label is used for representing whether the RFID label is an RFID label repeatedly put into the storeroom. For example, if the first attribute value of a certain RFID tag is 0, the RFID tag is characterized as being an RFID tag repeatedly put into the storage room, and if the first attribute value of a certain RFID tag is 1, the RFID tag is characterized as not being an RFID tag repeatedly put into the storage room. The repeatedly-inserted RFID tag is an RFID tag that is taken out of the refrigerator at a first time and inserted into the refrigerator at a second time, and the first time is earlier than the second time.

The first attribute value is used to distinguish whether or not the RFID tag is repeatedly put in the storage room, and the specific form of the first attribute value is not limited in the present application, similarly to the second attribute value. The first attribute value may be a state in which the identification information of the RFID tag is marked, such as marking the identification information of the repeatedly put-in RFID tag as a repeatedly put-in state and marking the identification information of the non-repeatedly put-in RFID tag as a non-repeatedly put-in state. The first attribute value may also be a different storage path corresponding to the RFID tag, such as storing the identification information of the repeatedly-placed RFID tag in a first table, storing the identification information of the non-repeatedly-placed RFID tag in a second table, 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 respectively generates food material controls according to each piece of food material information, and the food material controls corresponding to the RFID tags are generated to be in different states according to different first attribute values of the RFID tags.

In specific implementation, the controller may determine the first type of RFID tag according to the second 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, since the first attribute value of the RFID tag represents whether the RFID tag is a tag repeatedly put into the storage room, the food control corresponding to the RFID tag is generated to be in different states according to the difference of the first attribute value of the RFID tag, and a user can determine whether the RFID tag corresponding to the food control is a tag repeatedly put into the storage room according to the state of the food control. For example, for a certain RFID tag, if the first attribute value of the RFID tag indicates that the RFID tag is a repeatedly-placed RFID tag, a food material control in a first state is generated according to food material information corresponding to the RFID tag, and if the first attribute value of the RFID tag indicates that the RFID tag is not a repeatedly-placed RFID tag, a food material control in a second state is generated according to food material information corresponding to the RFID tag. Therefore, a user can quickly identify which food material controls correspond to the repeatedly put-in RFID tags according to whether each food material control in the food material management interface is in the first state or the second state.

In some embodiments, the controller of the refrigerator is further configured to: in the process of generating a food material management interface according to the first information set, judging whether a first attribute value of each first-class RFID label is a preset value or not; for a first type of RFID label with a first attribute value of a preset value, generating a food material control containing an explicit identification according to food material information corresponding to the RFID label, wherein the explicit identification is used for indicating that the RFID label corresponding to the food material control is a repeatedly-placed RFID label; and for the first type of RFID labels with the first attribute values not being preset values, generating the food material control not containing the explicit identification according to the food material information corresponding to the RFID labels.

According to the embodiments, whether the food contains the explicit identification depends on whether the first attribute value of the RFID tag is a predetermined value, and the food control is generated into two states, namely, a state when the food contains the explicit identification and a state when the food does not contain the explicit identification, according to whether the first attribute value of the RFID tag is the predetermined value. The user can identify whether the RFID label corresponding to the food material control is repeatedly put in according to whether the food material control displayed in the food material management interface contains the dominant mark.

Fig. 7 is a schematic view of a food material control according to an exemplary illustration 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 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, the food material control shown in fig. 8 does not include an explicit identifier 704.

For the repeatedly-placed RFID tags, the material identified by the RFID tags may change from one piece to another, for example, when a certain RFID tag is taken out, the material identified by the RFID tag is "radish" (attached to radish), and when the RFID tag is placed again, the material identified by the RFID tag is "apple" (attached to apple). In this case, the food material information corresponding to the locally stored RFID tag (repeatedly put in RFID tag) or the food material control corresponding to the RFID tag displayed in the food material management interface is not updated according to the food material information of the newly identified food material, so that confusion of the user is easily caused, and user experience is not facilitated.

To solve the problem, in some embodiments, a user may operate any one of the food material controls in the food material management interface to view detailed food material information corresponding to the food material control; when a user operates a food material control containing an explicit identification (namely, a food material control corresponding to a repeatedly-placed RFID label) in a food material management interface, a food material detail page is not displayed, but a prompt page is displayed to prompt the user that the RFID label corresponding to the food material control is the repeatedly-placed RFID label, so that the user is prompted to update the food material information corresponding to the RFID label in time according to actual conditions.

In addition, a control for triggering the display of the editing interface can be provided in the prompt page, so that the operation of a user is facilitated.

Based on this, the controller of the refrigerator is further configured to: receiving user operation of a user on a target food material control, responding to the user operation, and judging whether a first attribute value of an RFID label corresponding to the operated target food material control is a preset value or not; if the first attribute value of the corresponding RFID label is a preset value, presenting an interface prompt to prompt a user to update the food material information corresponding to the RFID label; and if the first attribute value of the corresponding RFID tag is not the preset value, presenting a food material detail page, wherein food material information corresponding to the target food material control is displayed in the food material detail page.

In addition, when a user inputs new food material information corresponding to a certain RFID tag by operating the editing interface, the received new food material information is used for replacing the locally stored original food material information, so as to update the food material information corresponding to the RFID tag.

Further, the controller of the refrigerator is also configured to modify the first attribute value of the first-type RFID tag when the food material information corresponding to the first-type RFID tag is updated, so as to mark the first-type RFID tag with the updated food material information as the RFID tag to be put into the storage room for the first time.

FIG. 9 illustrates an interface prompt, otherwise referred to as a prompt page, according to an exemplary embodiment of the present application.
