Description

Refrigerator and food material management interface display method

Technical Field

The application relates to the technical field of refrigerators, in particular to a refrigerator and a display method of a food material management interface.

Background

Currently, a multi-compartment refrigerator having a Radio Frequency Identification (RFID) function can intelligently manage food stored therein.

For example, an antenna is arranged in the freezing chamber and connected with an RFID detection module, and the RFID detection module can detect an RFID tag attached to a food material in the freezing chamber through the antenna in the freezing chamber and acquire food material information associated with the RFID tag, such as a food material name, a food material category, a food material shelf life, and the like. Thus, the refrigerator can know the food in the freezing chamber.

In practical application, the food material information associated with the plurality of RFID tags is the same, for example, the food material information associated with the plurality of RFID tags is information corresponding to "beef". When the plurality of RFID tags are placed in the refrigerator at the same time to identify a plurality of identical food materials, it is difficult for a user to distinguish the plurality of RFID tags, which is not favorable for user experience. Therefore, how to individually manage food materials corresponding to a plurality of RFID tags associated with the same food material information so that a user can distinguish the RFID tags and the food materials identified by the RFID tags is a technical problem to be solved urgently.

In order to realize intelligent management of food materials, the food materials in the storeroom are identified by using RFID labels. Specifically, identification information of the RFID tag, such as a tag code written in the RFID tag or a specific code segment in the tag code, 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 a specific implementation, the RFID detector 380 includes an RFID detection module disposed in each storage compartment, and the RFID detection module is configured to transmit a wireless signal in the corresponding storage compartment and receive a signal of an RFID tag in the storage compartment to obtain identification information of the RFID tag. In some embodiments, the RFID detection module may be specifically an antenna.

In a specific implementation, the controller 320 is connected to each RFID detection module, and controls the RFID detection module to identify a signal of the RFID tag in the storage compartment.

The controller draws a user interface according to the food material information corresponding to (associated with) each RFID tag in the storage room, and displays 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.

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 includes an RFID tag identification control, a recommended menu control, and a plurality of food material controls respectively corresponding to the RFID tags in the storage room. The user can identify and distinguish food materials in the refrigerator according to the food material control in the food material management interface.

And the controller generates a food material control in the food material management interface according to the food material information corresponding to the RFID tag in the storage room, and the food material control is used for representing the food material identified by the RFID tag. 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 the embodiments, the refrigerator controller determines the food material information corresponding to each RFID tag according to the correspondence between the identification information of the locally stored RFID tag and the food material information. In the correspondence relationship, the food material information corresponding to the identification information of the RFID tag is food material information corresponding to the RFID tag, or food material information related to the RFID tag. The identification information of the RFID tag may be a tag code of the RFID tag identified by the RFID detector, or may be a code segment in the tag code.

For example, the correspondence between the identification information of the locally stored RFID tag and the food material information may be as shown in table 1 below:

TABLE 1

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

For example, a correspondence table between the identification information of the RFID tag and the food material information may be 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, the controller responds to the instruction and starts to detect the signal of the RFID label placed in the sensing area so as to acquire the identification information of the RFID label. And after the controller acquires the identification information of the RFID label, presenting an editing interface containing the identification information on the display screen.

Fig. 5 is an editing interface shown in the present application according to an exemplary embodiment, and as shown in fig. 5, the editing 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.

For another example, a correspondence table between the identification information of the RFID tag and the food material information may be established and published on the server side. On the refrigerator side, the controller acquires the corresponding relation table from the server and stores the corresponding relation table locally; when food materials identified by the RFID tags in the refrigerator need to be displayed in the food material management interface, the controller searches food material information corresponding to the RFID tags from a locally stored corresponding relation table according to identification information of the RFID tags currently placed in the storage room, and finally generates corresponding food material controls in the food material management interface according to the food material information corresponding to the RFID tags.

In some embodiments, in the correspondence between the locally stored RFID tags and the food material information, the food material information associated with the plurality of RFID tags is the same. For example, as can be seen from the correspondence relationship shown in table 2 below, the food material information corresponding to the identifier 3, the identifier 4, and the identifier 5 is the same.

TABLE 2

RFID tag	Food material information
		Identification 1	Eggs, agricultural and sideline products
Identification 2	Cucumber and vegetable
		Identification 3	Beef and meat
Sign 4	Beef and meat
		Mark 5	Beef and meat
……	……

Because the food material control in the food material management interface is generated according to the food material information corresponding to each RFID tag in the storage room, when a plurality of RFID tags associated with the same food material information exist in the storage room, the display effects of the food material controls corresponding to the plurality of RFID tags in the food material management interface are the same, and it is difficult for a user to distinguish the plurality of RFID tags (identified food materials) through the food material control, without using user experience.

Fig. 6 is a food material management interface according to an exemplary embodiment of the present application, where the food material management interface displays a plurality of food material controls such as a food material control 601 corresponding to an RFID tag with identification information of "identification 3", a food material control 602 corresponding to an RFID tag with identification information of "identification 4", and a food material control 603 corresponding to an RFID tag with identification information of "identification 5" shown in table 2, and it can be seen that display effects of the food material control 601, the food material control 602, and the food material control 603 are substantially the same. As can be seen, the user cannot distinguish the food materials identified by the three RFID tags according to the three food material controls that appear substantially the same, for example, the user cannot take out the freshest food materials or the freshest food materials according to the three food material controls.

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 the specified attribute value of the RFID tag, that is, the specified attribute values of the first type RFID tag and the second type RFID tag are different. Illustratively, the assigned attribute value of the first type of RFID tag is 0, and the assigned attribute value of the second type of RFID tag is 1.

It should be noted that the specific form of the specified attribute value is not limited in the present application, and may be different status marks that the first type RFID tag and the second type RFID tag have, for example, the marked status of the first type RFID tag is a stored status, and the marked status of the second type RFID tag is a removed status, or different storage paths that correspond to the first type RFID tag and the second type RFID tag, such as storing the identification information of the first type RFID tag in a first table, storing the identification information of the second type RFID tag in a second table, and so on.

In some embodiments, the controller of the refrigerator is configured to: acquiring food material information associated with a target RFID label, wherein the target RFID label is an RFID label currently placed in the storage room, namely the first-type RFID label; and displaying a food material management interface according to food material information associated with the target RFID tags, wherein the food material management interface comprises food material controls corresponding to each target RFID tag, each food material control comprises an explicit tag identification, and the explicit tag identifications corresponding to the target RFID tags with the same associated food material information are different.

In the above embodiment, an explicit label identifier is added to the food material control to represent the RFID label corresponding to the food material control. When the food material control is generated according to the food material information corresponding to each target RFID label, the dominant label identifications corresponding to the target RFID labels with the same associated food material information are generated to be different. Therefore, the user can distinguish the RFID tags related to the same food material information according to the explicit tag identification, and the independent management of each RFID tag and the food material is realized.

In some embodiments, each RFID tag has an attribute identifier for characterizing the attributes of the corresponding dominant tag identifier of the RFID tag, wherein the attributes of the dominant tag identifier include content attributes, color attributes, and the like of the dominant tag identifier. Accordingly, the attribute identification of the RFID tag may include a first identification for determining the content presented by the overt tag identification, and a second identification for determining the color of the overt tag identification.

In some embodiments, the attribute identifier of the RFID tag may be specifically written in a specified code segment of a tag code of the RFID tag, and the attribute identifier of the RFID tag may be obtained by intercepting the specified code segment from the tag code.

In some embodiments, the tag code of the RFID tag includes a last food material predefined code, and the last food material predefined code is used for determining the food material information corresponding to the RFID tag. When the corresponding relation between the identification information of the RFID tag and the food material information is established, the food material information of the RFID tag is acquired from a mapping relation table of the food material predefined code and the food material information according to the food material predefined code of the RFID tag, and the acquired food material information and the identification information of the RFID tag are correspondingly stored locally, so that the corresponding relation between the identification information of the RFID tag and the food material information is obtained.

In some embodiments, the attribute identifications of the RFID tags associated with the same food material information are different, and further, although some food material information associated with some RFID tags is the same, the attribute identifications used for representing the attributes of the dominant tag identifications are different, so that the dominant tag identifications in the food material controls corresponding to the RFID tags are different, and further, the RFID tags are distinguished.

In some embodiments, the attribute identifications of any two RFID tags are different, and therefore, no matter whether the food material information associated with any two RFID tags is the same, any two RFID tags can be distinguished according to the attribute identifications thereof.

In some embodiments, in order to realize that the attribute identifications of the RFID tags associated with the same food material information are different, the food material predefined codes for determining the food material information associated with the RFID tags are written into another specified code segment of the tag codes together, so as to ensure that the attribute identifications of the RFID tags associated with the same food material predefined codes are different.

In other embodiments, the attribute identifier of the RFID tag may be attribute information stored in correspondence with the identification information of the RFID tag, and the attribute identifier of the RFID tag may be found in the local data according to the identification information of the RFID tag.

Based on this, in some embodiments, the controller of the refrigerator is configured to: acquiring an attribute identifier of a target RFID label and corresponding food material information, wherein the target RFID label is an RFID label currently placed in the storage room, namely the first-class RFID label; and displaying a food material management interface according to the attribute identification of the target RFID label and the corresponding food material information, wherein the food material management interface comprises food material controls corresponding to each target RFID label, each food material control comprises an explicit label identification, and the explicit label identifications corresponding to the target RFID labels with different attribute identifications are displayed to be different.

In a specific implementation, the controller may determine a target RFID tag from all the RFID tags according to the assigned attribute values of all the RFID tags stored locally; acquiring an attribute identifier and a uniqueness identifier of a target RFID tag from a tag code of the target RFID tag, wherein the uniqueness identifier of the target RFID tag is identification information of the target RFID tag; and finally, acquiring food material information corresponding to the target RFID tag from the corresponding relation stored locally according to the unique identifier of the target RFID tag.

In the above embodiment, an explicit label identifier is added to the food material control to represent the RFID label corresponding to the food material control. When the food control is generated according to the attribute identification of each target RFID label and the corresponding food material information, the attribute identifications represent the attributes of the content, the color and the like of the dominant label identification, so the dominant label identifications corresponding to different target RFID labels are different, and the attribute identifications of the RFID labels with the same associated food material information are different, or the attribute identifications of any two RFID labels are different, so the dominant label identifications corresponding to the RFID labels with the same associated food material information are different, or the dominant label identifications of any two food material controls are different, so that a user can distinguish the RFID labels with the same associated food material information according to the dominant label identifications, or distinguish any two RFID labels, and further realize the independent management of each RFID label and food material.

In some embodiments, the attribute identification of the RFID tag includes a first identification that is used to determine what is presented in the overt tag identification. In the embodiment of the present application, the content displayed in the dominant identifier is referred to as silk-screen content.

Specifically, the process that the controller displays the food material management interface according to the attribute identifier of the target RFID tag and the corresponding food material information includes: the controller determines target silk-screen content corresponding to the target RFID label according to the preset corresponding relation between the first identification and the silk-screen content; and displaying an explicit label mark containing the target silk-screen content in the food material control corresponding to the target RFID label. The silk-screen content may be numbers, characters, letters, patterns, and the like.

In some embodiments, the first identifier is an identifier corresponding to a first code segment of a tag identifier of the RFID tag, and the controller intercepts the first code segment of the target RFID tag to obtain the first identifier of the target RFID tag.

According to the preset corresponding relationship between the first identifier and the silk-screen content shown in the exemplary embodiment, as shown in the following table 3:

TABLE 3

First mark	Content of silk screen	First mark	Content of silk screen	First mark	Content of silk screen
						0A	A	0F	F	14	K
0B	B	10	G	15	L
						0C	C	11	H	16	M
0D	D	12	I	17	N
						0E	E	13	J	……	……

As can be seen from the preset corresponding relation between the first identification and the silk-screen content, the first identification of the RFID label is a 2-bit 16-system code, and the silk-screen content is letters.

It should be noted that the requirements of more RFID tags can be met by changing the number of the first identification bits and/or the form of the silk-screen content, so as to ensure that the first identifications of the RFID tags associated with the same food material information are different or that the first identifications of any two RFID tags are different.

Fig. 7 is a food material management interface according to an exemplary embodiment of the present application, where the food material management interface displays a food material control 701 corresponding to an RFID tag whose identification information is "identification 3", a food material control 702 corresponding to an RFID tag whose identification information is "identification 4", and a food material control 703 corresponding to an RFID tag whose identification information is "identification 5" shown in table 3, where the food material control 701, the food material control 702, and the food material control 703 respectively include

explicit tag identifications

7011, 7021, and 7031, and the

explicit tag identifications

7011, 7021, and 7031 are different. Specifically, the silk-screen content displayed on the dominant tag 7011 is the letter "a", the silk-screen content displayed on the dominant tag 7021 is the letter "D", and the silk-screen content displayed on the dominant tag 7031 is the letter "G".

In some embodiments, the silk-screen content corresponding to each RFID tag (i.e., the silk-screen content corresponding to the first identifier of the RFID tag) is identical to the silk-screen content printed on the RFID tag entity, and then, the user may correspondingly find the RFID tag printed with the same silk-screen content in the storage room according to the silk-screen content displayed by the dominant tag identifier, or correspondingly find the food material control corresponding to the RFID tag in the food material management interface according to the silk-screen content printed on the RFID tag entity.

Fig. 8 is an appearance schematic diagram of an RFID tag according to an exemplary embodiment of the present application, which is specifically an appearance schematic diagram of an RFID tag whose identification information is "identification 3" shown in table 3, and as shown in fig. 8, a silk-screen content 802 printed on a tag body 801 of the RFID tag is a letter "a". In actual use, a user can correspondingly find the RFID tag printed with the letter "a" in the storage room according to the dominant tag identifier 7011 displayed in the food material management interface shown in fig. 7, or the RFID tag printed with the letter "a" correspondingly finds the food material control corresponding to the RFID tag in the food material management interface.

In some embodiments, the content displayed by the dominant tag identification may further include a food material pictogram pattern preset according to the food material information associated with the RFID, that is, a silk-screen image. Specifically, the controller acquires a target silk-screen image corresponding to the target RFID tag according to a preset corresponding relation between the food predefined code and the silk-screen image; and displaying an explicit label mark containing the target silk-screen image in the food material control corresponding to the target RFID label.

In some embodiments, the attribute identification of the RFID tag includes a second identification that is used to determine the color of the overt tag identification. Based on this, the process that the controller displays the food material management interface according to the attribute identifier of the target RFID tag and the corresponding food material information further includes: determining a target color value and an RGB value corresponding to the target RFID label according to a preset corresponding relation between the second identifier and the silk-screen color value; and drawing the color of the dominant label mark corresponding to the target RFID label according to the target color value.

explicit tag identifications

9011, 9021, and 9031, and the colors of the

explicit tags

9011, 9021, and 9031 are different from those of the

explicit tag identifications

7011, 7021, and 7031 in the food material management interface shown in fig. 7.

In some embodiments, in order to implement partition management of food materials in multiple storage rooms, multiple food material display areas corresponding to the storage rooms are arranged in a food material management interface, and food material controls corresponding to the food materials in the storage rooms are displayed in the corresponding food material display areas, so that a user can conveniently and quickly identify which food materials are stored in which storage room.

In order to further facilitate the user to distinguish the food materials in different storage rooms, in some embodiments, the food material controls corresponding to the target RFID tags with the same second identifier are displayed in the same food material display area, and the food material controls corresponding to the target RFID tags with different second identifiers are displayed in different food material display areas. That is to say, 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.

In some embodiments, the controller of the refrigerator is further configured to: detecting opening and closing signals of the box doors through a detector connected with the detector, identifying the RFID tags in the storage chamber when all the box doors are detected to be closed (for example, when the closing signals of the box doors are detected, judging whether all the box doors are closed according to the recorded state of each box door, and if all the box doors are closed, determining that all the box doors are detected to be closed), and obtaining a zeroth information set containing the latest identified tag codes of each RFID tag; determining a newly moved RFID label and a newly put RFID label by comparing a zero information set with a first information set and a second information set which are locally stored, wherein the first information set comprises the RFID label with the designated attribute value as a first value, namely a first class of RFID labels, the second information set comprises the RFID label with the designated attribute value as a second value, namely a second class of RFID labels, and the second class of RFID labels are the RFID labels which are currently moved out of the storeroom; and modifying the specified attribute value of the newly removed RFID tag into a second value so as to mark the newly removed RFID tag as a non-target RFID tag, namely a second-type RFID tag, and modifying the specified attribute value of the newly put-in RFID tag into a first value so as to mark the newly put-in RFID tag as a first-type RFID tag.

Specifically, the newly removed RFID tag is an RFID tag whose identification information does not exist in the zeroth information set but exists in the first information set; the newly put RFID tags are RFID tags whose identification information exists in the zeroth information set and in the second information set at the same time, and RFID tags whose identification information exists only in the zeroth information set. It should be noted that, the manner of modifying the specified attribute value is different according to the specific form of the specified attribute value, and the present application is not limited thereto.
