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.

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

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 is provided with food material controls corresponding to the food materials 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 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, a freshness identifier of the food material, etc., 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 to show the time of putting the food material, the remaining shelf life, etc.

In some embodiments, in these 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 pre-established correspondence relationship between the 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 between 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 between the identification information of the RFID tag and the food information, which is established in advance, may be as follows:

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

In some embodiments, a table of correspondence between identification information of the RFID tag and food material information is established at the refrigerator side and stored locally. Specifically, when the food management interface is displayed on the display screen, a user can input an instruction for inputting food information by operating the food management interface, for example, the user clicks a food information input control provided by the food management interface to instruct to input food information; after 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, 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 food material information input by a user and can comprise an input position for inputting the food material information; after receiving the food material information input by the user at the editing interface, the controller correspondingly stores the received food material information and the identification information, thereby completing and perfecting the establishment of the corresponding relation table of the identification information and the food material information of the RFID tag.

For example, the user may click on an RFID tag identification control in the food management interface as shown in fig. 4 to enter an instruction indicating food information entry. After the controller receives the instruction input by the user, 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 management interface shown in fig. 4 in response to the instruction, and the signal of the RFID tag placed in the sensing area starts to be detected to acquire the identification information of the RFID tag. After the controller acquires the identification information of the RFID tag, an association interface containing the identification information is presented on a display screen.

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

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, virtual association between the RFID tag and the food material information is realized, and the same RFID tag can be successively corresponding to different food material information by modifying the corresponding relation between the RFID tag and the food material information, so that the use flexibility of the RFID tag is improved.

In practical application, the RFID tag put into use can be taken out and put into the refrigerator for a plurality of times, and for any RFID tag, when the RFID tag is put into the refrigerator again, the food material corresponding to the actual identification is or has been changed, 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 again, the food material identified by the RFID tag is "apple", and because 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", the confusion of the user is easily caused, and the user experience is not facilitated.

In addition, if a plurality of identical food materials are stored in the refrigerator, according to the above embodiment, it is known that a 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 it in 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, and the user experience is not friendly.

Embodiments that solve the above problems and enhance 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 second attribute value of the RFID tag, that is, the first type of RFID tag is different from the second attribute value of the second type of 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 above-mentioned 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 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 whether the RFID tag is an RFID tag that is repeatedly placed into the storage compartment. For example, if the first attribute value of a certain RFID tag=0, it is indicated that the RFID tag is an RFID tag repeatedly placed in the storage compartment, and if the first attribute value of a certain RFID tag=1, it is indicated that the RFID tag is not an RFID tag repeatedly placed in the storage compartment. The RFID tag repeatedly put in is an RFID tag taken out of the refrigerator at a first time and put in the refrigerator at a second time, and the first time is earlier than the second time.

The function of the first attribute value is to distinguish whether the RFID tag is a tag repeatedly placed in the storage compartment, 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 identification information of the RFID tag is marked, such as a state in which identification information of a repeatedly placed RFID tag is marked as a repeatedly placed state, and a state in which identification information of a non-repeatedly placed RFID tag is marked as a non-repeatedly placed 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 RFID tag that is repeatedly placed in the first table, storing the identification information of the RFID tag that is not repeatedly placed in the second table, 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 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 into different states according to the difference of the first attribute values of the RFID tags.

In specific implementation, the controller can determine the first type of RFID tags according to the second 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 whether the RFID tag is a tag that is repeatedly placed in the storage room, the food control corresponding to the RFID tag is generated into different states according to the difference of the first attribute values of the RFID tag, and the user can determine whether the RFID tag corresponding to the food control is a repeatedly placed tag according to the states 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 control in a first state is generated according to food 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 control in a second state is generated according to the food information corresponding to the RFID tag. Therefore, a user can quickly identify which food material controls correspond to the repeatedly placed 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: judging whether a first attribute value of each first type of RFID tag is a preset value or not in the process of generating a food management interface according to the first information set; for a first type of RFID tags with a first attribute value of a preset value, generating a food material control containing a dominant mark according to food material information corresponding to the RFID tags, wherein the dominant mark is used for indicating that the RFID tags corresponding to the food material control are repeatedly put in; and for the first type of RFID tags with the first attribute values not being the preset values, generating food material controls which do not contain the explicit identification according to the food material information corresponding to the RFID tags.

From these embodiments, it is known whether the food material contains the dominant identifier depends on whether the first attribute value of the RFID tag is a predetermined value, and the food material control is generated into two states, i.e., a state when the dominant identifier is contained and a state when the dominant identifier is not contained, depending on whether the first attribute value of the RFID tag is a predetermined value. The user can identify whether the RFID label corresponding to the food material control is repeatedly placed according to whether the food material control displayed in the food material management interface contains the dominant 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 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 food material control shown in fig. 8 does not include the overt identification 704.

For the repeatedly put-in RFID tag, the identified food material may change before and after, for example, when a certain RFID tag is taken out, the identified food material is "radish" (attached to the radish), and when the RFID tag is put in again, the identified food material is "apple" (attached to the apple). In this case, no matter the food material information corresponding to the locally stored RFID tag (the repeatedly placed RFID tag) or the food material control corresponding to the RFID tag displayed in the food material management interface is updated according to the food material information of the food material which is newly identified, so that confusion of users 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 (namely, a food material control corresponding to a repeatedly placed RFID tag) containing a dominant mark 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 tag corresponding to the food material control is the repeatedly placed RFID tag, so that the user is prompted to update food material information corresponding to the RFID tag in time according to actual conditions.

In addition, a control for triggering display of the editing interface can be provided in the prompt page so as to be convenient for a user to operate.

Based on this, the controller of the refrigerator is further configured to: receiving user operation of a user on a target food material control, and responding to the user operation, 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 tag is a preset value, presenting an interface prompt to prompt a user to update food material information corresponding to the RFID tag; if the first attribute value of the corresponding RFID tag is not the preset value, a food material detail page is presented, and 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 to replace the original food material information stored locally, so as to update the food material information corresponding to the RFID tag.

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

FIG. 9 is an interface prompt, or prompt page, according to an exemplary embodiment of the present application. As shown in fig. 9, the interface prompt is displayed at the upper layer of the food management interface, and prompts the user through text content that the food (i.e. RFID tag) corresponding to the control has been moved out of the refrigerator, i.e. the repeatedly placed food (i.e. RFID tag) is being repeatedly placed, and asks the user whether to re-edit the food. The interface prompt shown in fig. 9 also displays a control ("yes, de-editing") for triggering the display of the editing interface, when the user operates the control, the user jumps to the editing page shown in fig. 6, and the identification information of the corresponding RFID tag is displayed in the editing page.
