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 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.

Referring to fig. 4, the food material management interface comprises an RFID tag identification control, a recommended menu control and food material controls corresponding to each RFID tag in the storage room

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 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 the prior art, each RFID tag needs to be recognized one by one to read the identification information of each RFID tag, and the food material information to be associated with the RFID tag is input one by one, and then the recognized identification information and the input food material information are stored locally in a corresponding manner, so that the operation is complicated, and the user experience is not friendly enough.

Embodiments that can solve the above problems and improve the user experience will be described in detail below.

In some embodiments, the controller of the refrigerator is configured to: when all the box doors are detected to be closed, all the RFID tags in the storage room are identified, and the tag code of each RFID tag is obtained; judging whether the RFID tag is a newly added RFID tag or not according to the tag code of the RFID tag, wherein the newly added RFID tag is an RFID tag which is not associated with the food material information; if the RFID tag is the newly added RFID tag, acquiring preset food material information corresponding to the newly added RFID tag according to the tag code of the newly added RFID tag, and if the RFID tag is not the newly added RFID tag, acquiring food material information associated with the RFID tag according to the tag code of the RFID tag; and updating the food material management interface, wherein in the updated food material management interface, the food material control corresponding to each newly added RFID tag is generated according to the preset food material information corresponding to each newly added RFID tag, and the food material controls corresponding to other RFID tags are generated according to the food material information associated with the other RFID tags, wherein the other RFID tags are the identified RFID tags except for the newly added RFID tags.

In some embodiments, the controller detects the opening and closing signals of the doors through a detector connected with the controller to monitor the closing time of all the doors. The detection of the closing of all the doors means that the closing signal of the doors is detected and all the doors are closed when the closing signal is detected. For example, each time a door closing signal is detected, whether all doors are closed is determined according to the recorded state of each door, and if all doors are closed, it is determined that all doors are detected to be closed.

More specifically, the detector for detecting the opening and closing signals of the doors detects the opening and closing signals of each door, records the opening and closing state of each door according to the detected opening and closing signals, and sends the opening and closing state information to the controller, wherein the opening and closing state information comprises the latest two opening and closing states of each door.

For example, the process of changing the opening/closing state of the door is recorded by recording a previous state (Oldstate) and a subsequent state (Newstate) of the door, for example, when an opening signal of the door is detected, the subsequent state of the door is recorded as an open state (Newstate is open), the subsequent state (closed state) recorded before the detection of the opening signal is automatically updated as the previous state, and then, when a closing signal of the door is detected, the subsequent state of the door is recorded as a closed state (Newstate is closed), and the subsequent state (open state) before the detection of the closing signal is automatically updated as the previous state.

Illustratively, the contents of each field in the switch state information sent by the detector to the controller are as follows:

in some embodiments, the controller receives the switch state information sent by the detector, and analyzes the latest switch state of each box door and the change process of the switch state of each box door according to the received switch state information. And when the controller displays that the subsequent states of all the box doors are closed states and the previous state of at least one box door is an open state according to the received switch state information, determining that all the box doors are closed.

In the embodiment of the application, when the controller detects that all the box doors are closed, the controller instructs the RFID detectors connected with the controller to identify the RFID tags in all the storage rooms, and the tag code of each RFID tag is obtained.

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, respectively. The first code segment is used for writing a first code, and the first code is used as identification information of the RFID and has uniqueness; the second code segment is used for writing a second code, which is a predetermined code or a non-predetermined code. For the RFID label with the second code being the preset code, the corresponding food material information can be customized by a user; for the RFID tag with the second code being the non-predetermined code, the corresponding preset food material information is pre-stored in the cloud server and cannot be defined by a user.

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:

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 first code segment, which is not described herein.

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

RFID second encoding	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, 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.

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

Based on this, the controller of the refrigerator is further configured to: acquiring a first code written in the first code segment from the tag code of the identified RFID tag; searching whether a first code of the RFID tag exists in a local information set, wherein the local information set comprises the first code of the RFID tag which is associated with the food material information; if the first code of the RFID label does not exist in the local information set, the RFID label is judged to be a newly added RFID label; and if the first code of the RFID label exists in the local information set, judging that the RFID label is not the newly added RFID label.

For the RFID label which is associated with the food material information, the unique identification information (namely the first code) and the associated food material information are correspondingly stored in the local information set. It should be noted that other information, such as the complete tag code or the second code of the RFID tag, the status flag, the attribute identifier, the attribute value, and the like, may also be stored in the local information set.

In some embodiments, the controller is further configured to: if the identified RFID tag is a newly added RFID tag, namely the RFID tag which is not associated with the food material information is obtained, a second code written in the second code segment is obtained from the RFID tag; judging whether the second code of the RFID label is a preset code or not; if the second code of the RFID tag is a preset code, acquiring preset default filling information as preset food material information of the RFID tag; and if the second code of the RFID tag is not the preset code, acquiring the preset food material information corresponding to the RFID tag from the preset corresponding relation between the second code and the food material information according to the second code of the RFID tag.

In some embodiments, after the preset food material information corresponding to the newly added RFID tag is obtained, the tag code (the complete tag code or the first code and the second code) of the newly added RFID tag and the corresponding preset food material information are correspondingly stored in the local information set.

In the above embodiment, the default food material information may be food material information composed of a specified character string, such as "food material name: undefined", "food material category: undefined", "shelf life: undefined/60 days", and the like. Default food material information is used for generating a temporary food material control corresponding to the RFID label in a food material management interface before the RFID label is not associated with the food material information so as to instruct a user to edit the food material information of the RFID label by operating the temporary food material control; the default food material information is also used for occupying a data position in the local information set, that is, occupying a position to which the food material information associated with the RFID tag belongs, so that the food material information associated with the RFID tag is replaced by the food material information associated with the RFID tag after the user inputs the food material information associated with the RFID tag.

Fig. 5 is another food material management interface according to an exemplary embodiment shown in the present application, and as shown in fig. 5, compared with the food material management interface shown in fig. 4, a plurality of new food material controls in the interface, that is, food material controls corresponding to a plurality of new food material labels, specifically include food material controls 501, 502, and 503 generated according to default filling information, and food material controls 504 and 505 generated according to preset food material information. As shown in fig. 5, the food material control generated according to the default filling information is the same as other food material controls, and also includes a food material icon, a food material name, and the like, and is different from other food material controls in that an undefined tag is used as a food material name, an image file containing an undefined word is used as a food material icon, and it is explicitly shown that the corresponding RFID tag is not associated with the food material information yet, that is, the RFID tag is an undefined tag or is referred to as an unedited tag, so that the user is effectively reminded to edit the RFID tags in time.

According to the embodiment, by designing the tag code, each RFID tag is already corresponding to the specified food material information before being put into use by a user; on the basis, on the user side, when all the box doors are detected to be closed, the RFID tags in the storage room are identified, whether newly added RFID tags which are not associated with food material information appear or not is judged, batch identification of the newly added RFID tags is achieved, and each newly added RFID tag does not need to be identified one by one; for the newly added RFID tags, the corresponding preset food material information is obtained according to the tag codes of the newly added RFID tags, and the preset food material information is stored as the food material information associated with the newly added RFID tags, so that the association process of each newly added RFID tag and the corresponding food material information is realized through background processing, and the food material information to be associated with the newly added RFID tags does not need to be input one by a user, so that the user experience is more friendly; the food material management interface is updated according to the preset food material information, so that a user can timely sense the RFID tags and the food materials newly added in the refrigerator, and the user experience is further improved.

In practical applications, the RFID tag used by the user is an editable tag, that is, whether the associated food material information can be customized by the user, for example, the second code is an RFID tag with a predetermined code. As described above, if the second code of the newly added RFID tag is the predetermined code, the default filling information is obtained as the preset food material information, and is used to generate a temporary food material control in the food material management interface to prompt the user to edit the newly added RFID tag in time and occupy the data position in the local information set. In order to facilitate the user to quickly enter the editing interface, the user can operate the food material control corresponding to the newly added RFID tag to trigger jumping to the interface for editing the corresponding newly added RFID tag.

Specifically, the controller of the refrigerator is further configured to: receiving user operation, such as clicking operation, on the target food material control; responding to user operation, and judging whether the operated target food material control is a food material control generated according to default filling information; if the target food material control is a food material control generated according to default filling information, displaying a food material editing interface, wherein the food material editing interface is configured to receive target food material information input by a user; and if the target food material control is not the food material control generated according to the default filling information, displaying a food material detail interface, wherein food material information corresponding to the target food material control is displayed in the food material detail interface.

As a possible implementation manner, the controller may determine whether the target food material control is the food material control generated according to the default filling information according to whether the second code of the RFID tag corresponding to the target food material control is the predetermined code. If the second code of the RFID label corresponding to the target food control is the preset code, judging that the target food control is the food control generated according to the default filling information; and if the second code of the RFID label corresponding to the target food control is not the preset code, judging that the target food control is not the food control generated according to the default filling information.

The food material editing interface shown in the present application according to the exemplary embodiment may be an interface shown in fig. 6.
