The refrigerating compartment 101B is selectively opened or closed by a refrigerating compartment door 200B pivotably mounted on the refrigerating compartment 101B.

Fig. 2 is an appearance schematic diagram of a refrigerator according to an exemplary embodiment of the present application, and as shown in fig. 2, a display screen is provided on a refrigerating chamber door 200B, and the display screen is embedded in a door body. In some embodiments, the screen of the display screen is positioned in a plane flush with the outer surface of the door.

In some embodiments, the refrigerator further includes a controller connected to the display screen, and configured to interact with the server to obtain information and data, draw a user interface, and output a display signal to the display screen, where the display screen receives the display signal output by the controller and displays corresponding image information, such as the user interface.

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

In some embodiments, in order to achieve intelligent management of food materials, the food materials in the storage room are identified by using RFID tags, specifically, the food material types and/or food material names are converted into corresponding food material codes and written into the RFID tags, so that the food material codes become a part of the tag codes, association between the RFID tags and the food materials is achieved, and then the food materials attached with the RFID tags are stored in the refrigerator. The refrigerator acquires the tag codes written in the RFID tags by detecting the signals of the RFID tags, and analyzes the food material information from the tag codes.

In some embodiments, an RFID detection module is arranged in each storage room, and the RFID detection module is used for transmitting a wireless signal in the corresponding storage room and receiving a signal of an RFID tag in the storage room so as to acquire the food material information in the RFID tag. In some embodiments, the refrigerator includes a sensing area that specifically identifies the RFID tag, and an RFID detection module is provided at the sensing area for detecting the RFID tag placed in the area, such as a tag identification area.

In some embodiments, the refrigerator may further include an RFID processing module, which is respectively connected to each RFID detection module, and configured to control the RFID detection module to transmit a wireless signal and receive a signal of the RFID tag fed back by the RFID detection module.

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

In some embodiments, the controller draws a user interface according to the food material information corresponding to 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.

In some embodiments, the controller is configured to: and generating a food material management interface according to the scanned signal of the RFID tag, and displaying the food material management interface on a display screen. The food material management interface can comprise a plurality of food material display areas and function controls, one food material display area can correspond to one food material category or one storage room, and each food material display area is used for displaying food material information corresponding to the RFID tag in the refrigerator. And displaying the food material information of the corresponding category in the food material display area corresponding to the food material category, and displaying the food material information of the food material in the corresponding storage chamber in the food material display area corresponding to the storage chamber. The food material information displayed in the food material management interface includes, but is not limited to, a food material icon, a food material name, and a freshness identifier of a food material, wherein the food material icon can be generated according to a pictographic picture of the food material, and the freshness identifier of the food material is used for showing any one or more of the placement time, the remaining time when the distance is expired, and the expiration time of the food material. The functional controls in the food material management interface include, but are not limited to, a control for triggering identification of the RFID tag, a control for adding food material information, and a control for displaying menu information, etc.

Fig. 3 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. 3, the food material management interface is divided into two display areas, left and right; the left area comprises an RFID tag identification control and food material display areas corresponding to food material categories, such as fruits and vegetables, wherein food material icons and food material names of the corresponding categories are displayed in each food material display area; the right area comprises recommended menu controls and food material display areas corresponding to the storage chambers, such as a refrigerating chamber, a temperature changing chamber, a freezing chamber and the like, and corresponding food material icons and food material names are displayed in each food material display area.

In the above embodiment, the association between the RFID tag and the food material is realized by converting the food material type and/or the food material name into the corresponding food material code and writing the food material code into the RFID tag. For example, the RFID tag is placed in a designated area of the reading and writing device, the food material type and/or food material name input by the user in the corresponding operation interface is received, the food material type and/or food material name input by the user is converted into a food material code, and the food material code is written into the RFID tag. The association method is not only complicated in operation, but also cannot be changed once the food material codes are written, so that the use flexibility of the RFID tag is poor, and the RFID tag cannot be recovered if the operation is wrong.

In order to solve the above problems, in some embodiments, the virtual association between the RFID tags and the food material information is realized by establishing the corresponding relationship between the RFID tags and the food material information, and an operation of writing in the food material information is not required to be performed for each RFID tag, and the corresponding relationship between the RFID tags and the food material information is modified, so that the same RFID tag sequentially corresponds to different food material information, thereby improving the flexibility in use of the RFID tags.

It should be noted that there are various ways to establish the corresponding relationship between the RFID tag and the food material information, and several specific implementation manners will be given below.

In some embodiments, the corresponding relationship between the identification information of the RFID tag and the food material information is established in advance, so as to realize the virtual association between the RFID tag and the food material. 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. In the embodiments, the refrigerator controller determines food material information corresponding to each RFID tag according to the identification information of each RFID tag and a pre-established correspondence.

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 the above embodiment, by establishing the corresponding relationship between the identification information of the RFID tag and the food material information, the virtual association between the RFID tag and the food material is realized, and it is not necessary to perform information writing operation on each RFID tag, and it is only necessary to store the identification information and the specified food material information in the database after obtaining the identification information of the RFID tag. Moreover, the same RFID tag can be sequentially associated with different food materials by modifying the corresponding relation, so that the problem that the food material information cannot be changed once written in is solved, and the use flexibility of the RFID tag is improved.

In some embodiments, a correspondence table of the identification information of the RFID tag and the food material information is 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 user interface, the controller instructs the RFID detection module to detect information of the RFID tags in the refrigerator so as to obtain tag codes of the RFID tags, analyzes identification information of the RFID tags from the tag codes, determines food material information corresponding to the identification information of the RFID tags according to a locally stored corresponding relation table, and finally displays the user interface according to the food material information corresponding to the RFID tags.

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; after receiving the instruction, the controller starts to detect a signal of the RFID tag placed in the designated area to acquire identification information of the RFID tag, and displays an association interface for associating the RFID tag with food material information, wherein the acquired identification information of the RFID tag is displayed in the association interface, and the association 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 association 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.

As shown in fig. 3, a user may click on an RFID tag identification control in the interface 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. 4) 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. 3, 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. 5 is an association interface shown in the present application according to an exemplary embodiment, and as shown in fig. 5, the association 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 association 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 tags and the food material information, the virtual association between the RFID tags and the food material information is realized, the operation of writing in the food material information into each RFID tag is not required, and the corresponding relation between the RFID tags 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 other embodiments, the tag code of the RFID tag includes at least two code segments, a first code segment and a second code segment. Wherein the first code segment is used for writing a first code, which may be a predetermined code or a non-predetermined code. For the RFID label with the first code being the preset code, the corresponding food material information can be customized by a user; for the RFID tag with the first code being the non-preset code, the corresponding preset food material information is pre-stored in the cloud server and cannot be defined by a user. The second code segment is used for writing a second code which is the unique identification information of the RFID label.

In some embodiments, at least two code segments included in the tag code of the RFID tag conform to a preset composition rule, and after the tag code is obtained, the controller intercepts the first code segment and/or the second code segment according to the preset composition rule to obtain the first code and/or the second code, so that a process of analyzing long code information is saved, and processing efficiency is improved.

In some embodiments, the predetermined code has uniqueness, such as 00; the non-predetermined code has no uniqueness, and may be multiple, and one non-predetermined code corresponds to one food material information.

Illustratively, the tag encoding structure of an RFID tag is as follows:

for example, if the controller acquires that the tag code of the RFID tag is "01123456789012345678901234", the first code may be intercepted as "01" and the second code may be intercepted as "123456789012345678901234" according to the preset composition rule.

It should be noted that, according to different requirements, the tag code of the RFID tag may further include more code segments, such as a third code segment for writing the manufacturer identifier of the RFID tag, and further, such as a fourth code segment for serving as a reserved bit of the tag code, so as to improve the expandability of the RFID tag. In other embodiments, the manufacturer identifier of the RFID tag may also be included in the second code segment, which is not described herein.

For example, the correspondence relationship between the first code (non-predetermined code) and the food material information may be as shown in the following table:

RFID first code	Food material name	Food material category
			01	Radish (radish)	Vegetable products
02	Carrot (Carex sativus L.)	Vegetable products
			03	Lotus root	Vegetable products
……	……	……

In some embodiments, the controller is configured to: responding to an instruction which is input by a user and used for indicating to identify the RFID label, and acquiring a label code of the RFID label; then judging whether the first code is a preset code; if the first code is a preset code, displaying a first association interface, wherein the first association interface is configured to receive target food material information input by a user, and the target food material information is the food material information defined by the user for the RFID tag; and after receiving the target food material information input by the user on the first association interface, associating the target food material information with the RFID tag.

In some embodiments, associating the target food material information with the RFID tag means that the target food material information and a second code of the RFID tag (i.e. identification information of the tag) are correspondingly stored in local data, and in the local data, a correspondence between the food material information and the second code of the RFID tag is used for searching for the food material information corresponding to the tag under the condition that the second code of the tag is known.

In some embodiments, associating the target food material information with the RFID tag further comprises generating a food material ID according to a current time, and correspondingly storing the food material ID in local data together with the second code of the RFID tag and the target food material information, wherein the current time includes, but is not limited to, a time when the target food material information is received by the designated controller.

In some embodiments, the user may input an instruction for instructing tag identification by operating the food material management interface, for example, the user clicks an RFID tag identification control in the food material management interface shown in fig. 3 to input the user instruction. When the controller receives an instruction for instructing tag identification, a TOEST prompt (shown in FIG. 4) for prompting a user to place the RFID tag in the sensing area is displayed on the food material management interface, and an RFID detection module in the sensing area is instructed to start to identify the RFID tag so as to acquire a tag code of the RFID tag. In some embodiments, the first association interface comprises one or more input positions for inputting one or more items of target food material information, and when a click operation of a user on the input positions is detected, the input positions are activated to receive text information input by the user, namely the target food material information. According to the difference of elements and layout in the first association interface, the target food material information input by the user in the first association interface includes but is not limited to a food material name, a shelf life of the food material and the like.

Fig. 5 is a user interface, specifically an exemplary first association interface, according to an exemplary embodiment of the present application. As shown in fig. 5, the first correlation interface includes an input location corresponding to a food material name and an input location corresponding to a food material shelf life.

Correspondingly, if the first code is not the preset code, the preset food material information of the RFID tag is obtained according to the first code, and the preset food material information is associated with the RFID tag. In some embodiments, associating the preset food material information with the RFID tag means that the preset food material information and the second code correspondence of the RFID tag are stored locally. In some embodiments, associating the preset food material information with the RFID tag further includes generating a food material ID according to a current time, and correspondingly storing the food material ID in the local data together with the second code of the RFID tag and the preset food material information, where the current time includes, but is not limited to, a time when the specified controller obtains the preset food material information.

In specific implementation, the controller can acquire corresponding preset food material information from the cloud server according to the first code. Or, the controller may obtain the corresponding preset food material information from a locally preset correspondence table of the first code and the food material information according to the first code. The local preset corresponding relation table can be obtained by downloading the controller from the cloud server in advance.

In the above embodiment, whether the food material information corresponding to the RFID tag is customizable by the user is determined according to whether the first code is a predetermined code, and if the first code is the predetermined code, it is determined that the food material information corresponding to the RFID tag is customizable by the user, so that a first association interface capable of inputting target food material information is displayed, the received target food material information corresponds to the RFID tag, and the use flexibility of the RFID tag is improved; if the first code is not the preset code, which indicates that the food material information corresponding to the RFID tag cannot be defined by the user, the corresponding preset food material information is obtained according to the first code, the preset food material information corresponds to the RFID tag, user operation is saved, and food material information input efficiency is improved.

In some embodiments, when the first association interface is displayed, whether the food material information corresponding to the second code exists in the local data is determined according to the second code (i.e. the identification information of the RFID tag), and if the food material information corresponding to the second code exists in the local data, the food material information corresponding to the second code is used to pre-fill the corresponding input position in the first association interface. Therefore, on one hand, the currently associated food material information of the RFID tag can be displayed to the user, and on the other hand, if the user wants to modify the currently associated food material information, new food material information is input at each input position. In addition, if the user only wants to modify part of the food material information, the user only needs to re-input the part of the food material information, and the user does not need to re-input the other part of the food material information which is not wanted to be modified. If the food material information associated with the RFID tag does not exist in the local association data, pre-filling a corresponding input position in the first association interface with a preset character, such as "undefined" shown at the input position in FIG. 5.

In some embodiments, if the first code is not the predetermined code, a second association interface containing the preset food material information is displayed on the display screen, and the second association interface cannot receive the food material information input by the user, which is different from the first association interface. FIG. 6 illustrates a user interface, which is embodied as an exemplary second association interface, according to an exemplary embodiment of the present application. As shown in fig. 6, the food material name "radish" and the shelf life "60 days" are displayed on the second correlation interface.

The embodiment of the application also provides a food material information association method, which is applied to the refrigerator shown in fig. 1-6, and the execution main body of the method includes but is not limited to a controller of the refrigerator. Fig. 7 is a flowchart of a food material information association method according to an exemplary embodiment shown in the present application, and as shown in fig. 7, the method may include:

In response to the instruction, the signal of the RFID tag is identified by the RFID detection module to obtain the tag code of the RFID tag.

In this embodiment, the tag code includes a first code, and the first code is a predetermined code or a non-predetermined code representing that the preset food material information corresponding to the RFID tag is pre-stored in the cloud server and is not customizable by the user.

In some embodiments, the tag code further includes a second code that is unique identification information for the RFID tag.

In some embodiments, the tag code of the RFID tag includes at least two code segments, a first code segment and a second code segment, in compliance with a predetermined composition rule, wherein the first code segment is used for writing the first code, and the second code segment is used for writing the second code. Based on this, when the tag code of the RFID tag is obtained, the first code segment and/or the second code segment may be intercepted according to the preset composition rule of the tag code to obtain the first code and/or the second code.

According to the difference of elements and layout in the first association interface, the target food material information input by the user in the first association interface includes but is not limited to a food material name, a shelf life of the food material and the like.

An exemplary first correlation interface may be shown in fig. 5, where the first correlation interface includes an input location corresponding to a name of the food material and an input location corresponding to a shelf life of the food material.

Step 704, associating the target food material information with the RFID tag after receiving the input target food material information.

In specific implementation, the corresponding preset food material information can be acquired from the cloud server according to the first code. Or, the corresponding preset food material information may be acquired from a corresponding relation table of a locally preset first code and the food material information according to the first code. The local preset corresponding relation table may be obtained by downloading from the cloud server in advance.

Step 706, associating the preset food material information with the RFID tag.

In some embodiments, associating the preset food material information with the RFID tag means that the preset food material information and the identification information of the RFID tag are correspondingly stored in local data.
