In some embodiments, a food material management interface is displayed on the display screen 210, and the user manages food materials in the refrigerator by operating the food material management interface. For example, corresponding food material controls/icons are drawn in the food material management interface according to the food material information associated with each RFID tag in the storage room, so that the food materials in the refrigerator are displayed in the forms of icons, pictures and texts, and the like. In addition, functional controls, such as an RFID tag editing control, a food material adding control, and the like, can be drawn in the food material management interface, so that a user can operate the functional controls to trigger the controller 220 to implement corresponding functions.

In some embodiments, the food material management interface may include a plurality of food material display areas, one food material display area may correspond to one storage chamber, and the food material icons of the food materials in the storage chambers are displayed in the food material display areas corresponding to the storage chambers, so that the food materials in the refrigerator are displayed in the food material management interface in a partitioned manner. For example, food material icons of the food materials in the refrigerating chamber are displayed in the food material display area corresponding to the refrigerating chamber. The food material icons displayed in the food material management interface include but are not limited to food material pictures, food material names and freshness identifiers of food materials. The food material picture can be a pictographic picture of a food material, the freshness identification of the food material is used for showing any one or more of the input time of the food material, the remaining time away from expiration and the expiration time, wherein the remaining time away from expiration is determined according to the input time of the food material and the shelf life of the food material. It is to be understood that the food material picture, the food material name, the freshness identification of the food material, etc. may be part of, i.e. comprised in, the food material icon.

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 includes an RFID tag editing control 301, a recommended menu control 302, and an add food material control 306, and further includes food material display areas corresponding to the storage chambers, such as a food material display area 303 corresponding to the cold storage chamber, a food material display area 304 corresponding to the temperature-changing chamber, and a food material display area 305 corresponding to the cold temperature chamber. Food material icons corresponding to the food materials in the storage chamber are displayed in each food material display area, such as food material 1, food material 2 and food material 3 in the food material display area 303, food material 4 and food material 5 in the food material display area 304, and food material 6 and food material 7 in the food material display area 305. Each food material icon comprises a food material picture, a food material name and a freshness identification of the food material. Taking food material 3[3031] as an example, the food material comprises a food material picture 30311, a food material name of food material 1 (30312) and a freshness identifier 30313. It should be noted that, in fig. 3, since the food material 1 is expired, the stamp mark having the word "expired" is displayed on the food material picture as the freshness mark of the food material 1, so that the user can quickly notice the expired food material in the refrigerator.

In some embodiments, when the remaining number of days from expiration of the food material is less than a preset number of days, a specific remaining number of days is explicitly shown by the freshness indicator. For example, in the food material management interface shown in fig. 3, since the remaining days from the expiration of the food material 4[3041] is less than the preset number of days, the freshness indicator [30411] of the food material 4 includes a text prompt of "2 days remaining", so that the user can quickly obtain the remaining days of the food material to be expired.

In a specific implementation, the food material management interface may be an interface of a food material management related application operated by the controller 220, and the user may trigger and display the food material management interface on the food material management related application. When the food material management related application receives user operation for triggering display of the food material management interface, the food material information set is read from the memory, and corresponding food material icons are displayed in the food material management interface according to the food material information in the food material information set.

In some embodiments, the tag encoding of the RFID tag may include one or more code segments.

In some embodiments, the tag code of the RFID tag includes a plurality of code segments that conform to a preset composition rule, and after the tag code is obtained, the controller intercepts the code segment corresponding to the tag identifier according to the preset composition rule to obtain a unique identifier of the tag, that is, the tag identifier. One code segment in the label code is used as the label identification of the RFID label, and the identification length is shortened, so that the efficiency of the identification comparison process can be improved.

In some embodiments, the RFID tags may include predefined tags and custom tags, where the predefined tags are associated with preset food material information in advance and cannot be changed or defined by a user; the custom tag can be associated with the food material information input by the user, and can be defined by the user. When an RFID tag is given, it can be distinguished as either a custom tag or a predefined tag according to its tag code. For example, a specific code segment encoded by its tag is a predefined code 00, it is a custom tag, and a specific code segment encoded by its tag is not a predefined code 00, it is a predefined tag.

In some embodiments, an instruction for instructing to edit the food material information may be input in the food material management interface, or an RFID tag to be edited may be directly placed on the tag reading area, so as to trigger a process of establishing an association relationship between the food material information and the custom tag.

Specifically, when the food material management interface is displayed on the display screen, the user clicks a food material information editing control provided by the food material management interface to input an instruction for instructing to edit the food material information. After receiving the instruction, the controller displays a label scanning interface, displays a scanning prompt in the label scanning interface, and scans signals of the RFID label on the label reading area through the RFID module and the antenna 230. Wherein, by displaying the scan prompt, the user is prompted to place the RFID tag to be edited on the tag reading area. According to the scanning prompt, the user places the RFID tag to be edited on the tag reading area, and the RFID module and the antenna 230 scan the RFID tag on the tag reading area and acquire the tag coding information of the tag. Then, the controller intercepts an appointed code segment from the label code, judges whether the label is a self-defined label according to whether the appointed code segment is a preset code or not, judges that the label is the self-defined label if the appointed code segment is the preset code, intercepts a label identification from the label code at the moment, and displays a food material editing interface.

Or, the user directly places the RFID tag to be edited on the tag reading area without clicking the food material information editing control on the food material management interface. And the controller responds to the detection of the RFID label on the label reading area and displays the food material editing interface.

In some embodiments, the user may also instruct the instruction for editing the food material information by speaking a preset voice password. For example, the user speaks: "tag editing". When voice data input by a user is received and the content is recognized as 'tag editing', the fact that an input preset voice instruction for triggering the food material information corresponding to the RFID tag to be edited is received is confirmed. At this time, the controller displays a tag scanning interface in response to the instruction, and starts detecting the RFID tag on the tag reading area. And when the RFID label on the label reading area is detected, displaying a food material editing interface. The user can input food material information in the food material editing interface, and after the controller receives the food material information input by the user, the controller associates the food material information with the RFID tag and stores the association relationship locally. And if the appointed code segment intercepted from the label code is not the preset code, judging that the label is the predefined label, at the moment, acquiring preset food material information corresponding to the predefined label according to the food material code contained in the label code of the label, displaying a food material editing interface according to the preset food material information corresponding to the label, and prompting a user that the label cannot be marked. The corresponding relation between the food material codes and the preset food material information can be stored in the cloud and preset locally.

For ease of illustration, the RFID tag to be edited on the tag read area is referred to in some embodiments as a target tag.

In some embodiments, at least one editing item is displayed in the food material editing interface, each editing item includes an item name and an item content, where the item content is a portion to be edited, and a user can input food material information for associating with the target tag by inputting the item content of each editing item at the input position. After the input is finished, the controller correspondingly stores the input food material information and the identification information of the target tag in the food material information set, so that the establishment of the association relationship between the target tag and the food material information is finished.

For example, the editing items in the food material editing interface may include a food material name editing item, a food material shelf life editing item, a food material quantity editing item, and the like. It should be understood that the item name of the food material name editing item may be a "tag name", the item content is a name of a food material to be input, the item name of the food material shelf life editing item may be a "shelf life", the item content is a shelf life to be input, the item name of the food material quantity editing item may be a "quantity", and the item content is a quantity to be input. In addition, the identification information of the target label to be edited can be displayed in the food material editing interface, so that a user can visually see the identification information of the target label without manually inputting the identification information by the user, and the user experience is improved.

It can be seen that the food material information set is a set of all food material information stored by the controller and corresponding tag identification information thereof. It is worth noting that each group of food material information and identification information in the food material information set has two state information, namely a tag state and a storage state. The label state can be a first state and a second state, and the storage state can be a removal state and a placement state. The specific functions of the tag status and the storage status will be described in detail in the following embodiments.

It should be noted that the target tag that is placed on the tag reading area by the user for scanning and editing may be a brand new tag that is not associated with any food material information, or may be an old tag that is already associated with a certain food material. For a brand-new tag, the food material information input by the user in the food material editing interface is directly used for being associated with the tag; for the old tag, the food material information input by the user in the food material editing interface is used for replacing the food material information associated with the tag in advance.

Fig. 4 is a food material editing interface according to an exemplary embodiment of the present application, as shown in fig. 4, identification information "20200005" of an RFID tag is displayed on the food material editing interface, so that a user does not need to manually input the identification information, thereby avoiding an input error and saving user operations. A plurality of editing items, namely a food material name editing item 410, a food material shelf life editing item 420 and a food material quantity editing item 430 are also displayed, wherein each food material editing item corresponds to an input position for inputting the content of the corresponding item. In addition, a "cancel" control 440 and a "determine" control 450 are displayed. After the information input is finished, the user can click the 'confirm' control to indicate that the input food material information is stored, or click the 'cancel' control to indicate that the input food material information returns to the upper-level interface.

In some embodiments, the process of the controller displaying the food material editing interface may include: firstly, judging whether corresponding food material information exists in a food material information set or not according to identification information of a target tag; if the food material information corresponding to the target tag exists in the food material information set, item content corresponding to an editing item is displayed in a food material editing interface according to the food material information corresponding to the target tag; and if the corresponding food material information does not exist in the food material information set, displaying item contents corresponding to the editing items in a food material editing interface according to the preset filling information.

In an example, determining whether the food material information set has corresponding food material information according to the identification information of the target tag specifically includes: apple, 60 days, 1000g, the displayed food material editing interface is as shown in fig. 5. Referring to fig. 5, in the food material editing interface, the item content corresponding to the "label name" is "apple", the item content corresponding to the "shelf life" is "60 days", and the item content corresponding to the "quantity" is "1000 g". Through the food material editing interface, a user can know the food material information associated with the target tag in advance, and can input new food material information by modifying displayed item content.

In another example, if it is determined that there is no corresponding food material information in the food material information set according to the identification information of the target tag, the displayed food material editing interface is as shown in fig. 6. Referring to fig. 6, in the food material editing interface, the item contents corresponding to the "label name", "shelf life", and "quantity" are all predefined padding characters "undefined". Through the food material editing interface, a user can know that a target label is a brand-new label, and can input food material information used for being associated with the target label by inputting the item content of each editing item.

In some embodiments, after the food material information input is completed, the user can input a confirmation operation by clicking a "confirm" control on the food material editing interface. The controller responds to the received confirmation operation input by the user on the food material editing interface, correspondingly stores the received food material information input by the user and the identification information of the target label in the food material information set, marks the label state corresponding to the food material information and the label identification information in the food material information set as a first state, and marks the corresponding storage state as a putting-in state.

Before storing the input food material information and the identification information of the target tag, judging whether the food material information corresponding to the target tag exists in the food material information set or not according to the identification information of the target tag; if the food material information corresponding to the target tag exists in the food material information set, the input food material information is used for covering the food material information corresponding to the target tag in the food material information set, the tag state corresponding to the food material information set is marked as a first state, and the storage state is marked as a putting-in state. If the food material information corresponding to the target tag exists in the food material information set, the input food material information and the identification information of the target tag are directly and correspondingly stored in the food material information set, and the corresponding tag state is marked as a first state, and the storage state is marked as a putting-in state.

In addition, the controller also cancels the food material editing interface, displays the food material management interface and updates the food material management interface according to the input food material information in response to the confirmation operation. And adding a food material icon generated according to the input food material information in the updated food material management interface, namely, the added food material icon corresponds to the food material associated with the target tag. It is noted that compared to other food material icons in the food material management interface, the newly added food material icon includes a distinctive display feature.

In the concrete implementation process, when the controller receives a confirmation operation input by a user on the food material editing interface, the food material information input by the user and the identification information of the target label are correspondingly stored in the food material information set, the label states corresponding to the group of food material information and the identification information are marked as a first state, the corresponding storage states are marked as a putting-in state, and then a working thread for updating the interface is started. After the working thread is started, according to the food material information of which the label state is the first state in the food material information set, a food material icon containing a distinguishing display characteristic is generated in a food material management interface.

Fig. 7 is another food material management interface shown in the present application according to an exemplary embodiment, which may specifically be a food material management interface displayed after a user clicks a "confirmation" control when the food material editing interface shown in fig. 4 is displayed, and meanwhile, the food material management interface displayed after the food material management interface shown in fig. 3 is updated according to the food material information input by the user in the food material editing interface shown in fig. 4. It can be seen that, compared to the food material management interface shown in fig. 3, a food material icon [3032] of the food material 8 is newly added to the food material management interface shown in fig. 7, and different from the icons of the food material 1, the food material 2 and the like in the interface, the food material icon of the food material 8 includes a distinguishing display feature, and the distinguishing display feature is specifically a background identifier.

It should be understood that the distinctive display feature may also be other forms of display features, such as a "new" character as shown in fig. 8, or a dot-like logo with a particular color (e.g., red) as shown in fig. 9.

According to the embodiment, after the user finishes editing the tag, the user does not need to manually operate, and the user does not need to wait for the tag and the associated food materials to be placed into the refrigerator, so that the food material management interface can immediately respond to the tag and display the food material icon corresponding to the newly edited tag, and the user experience is improved.

It can be understood that, if the user wants to store food in or take out the storage room, the door needs to be opened or closed. Based on this, in some embodiments, the user's operation of closing the last door in the opened state may trigger the controller 220 to check the food in the storage room. It should be noted that the checking means that the controller scans all RFID tags in the storage room through the RFID module and the related antenna, and the checking result is the scanned tag information. The relevant antenna here refers to an antenna for scanning RFID tags in the storage room, such as a second antenna provided in the storage room. After the checking is finished, the controller updates the food material icons in the food material management interface according to the checking result, and then displays the latest food material storage condition to the user in time.

Specifically, when it is monitored that the last door in the open state is closed, the controller scans the RFID tags in the storage chambers through the RFID module and the second antenna, and intercepts the identification information of the RFID tags from the read encoded information of the RFID tags. Then updating the storage state and/or the tag state of the food material information in the food material information set according to the identification information of each tag in the storage room; and finally, starting a working thread for updating the food material management interface, and updating the food material icons in the food material management interface according to the updated food material information set by using the working thread.

It should be noted that, updating the storage state and/or the tag state of the food material information in the food material information set according to the identification information of each tag in the storage room specifically includes: comparing the identification information of each label in the storage room with the identification information in the food material information set, and determining the latest removed label and the latest put label; the tag which is checked this time but does not exist in the food material information set or is marked as a taken-out state is a latest put-in tag, and the tag which is not checked this time but is marked as a taken-in state in the food material information set is a latest taken-out tag. Marking the storage state corresponding to the latest moved-out label as a moved-out state, and marking the storage state corresponding to the latest put-in label as a put-in state; and marking the tag states corresponding to all tags in the food material information set as a second state.

In this way, after the working thread is started, the corresponding food material icon is displayed or updated in the food material management interface according to the food material information of which the storage state is the putting-in state in the food material information set, and the corresponding food material icon in the food material management interface is deleted according to the food material information of which the storage state is the taking-out state in the food material information set.

It should be understood that compared with the food material management interface before updating, some updated food material management interfaces display new food material icons, which represent that the user stores the food materials in the storage room before closing the door at this time; in some updated food material management interfaces, some food material icons are removed, and represent that a user takes out the food materials from the storage chamber before closing the door at this time; and in some updated food material management interfaces, the freshness identifiers of some food material icons are updated, and the like.

In addition, it is noted that in the food material management interface updated according to the inventory result, all food material icons do not have a distinctive display feature. Specifically, before the corresponding food material icon is displayed or updated according to the food material information in the food material information set, the tag state of the food material information is also judged, for the food material information in which the storage state is the put-in state and the tag state is the first state, the food material icon with the distinguishing display characteristic is displayed in the food material management interface, and for the food material information in which the storage state is the put-in state and the tag state is the second state, the food material icon without the distinguishing display characteristic is displayed in the food material management interface. Before the food material management interface is updated, the tag states corresponding to all food material information in the food material information set are marked as the second state, so that all food material icons do not contain distinguishing display characteristics in the updated food material management interface according to the counting result.

Fig. 10 is a food material management interface according to an exemplary embodiment of the present application, which is specifically an interface displayed after the food material management interface shown in fig. 7 is updated according to an inventory result. As can be seen, compared with the interface shown in fig. 7, in the updated interface shown in fig. 10, a food material icon of "food material 9" is added in the food material display area corresponding to the refrigerating chamber. The food material icon of "food material 10" is newly added in the temperature changing chamber, and the food material icon of "food material 5" originally in the temperature changing chamber disappears. In addition, the distinctive display feature on the food material icon of "food material 8" disappears.

In the above embodiment, the controller 220 detects the opening and closing signal of each door by the detector 240, and records the opening and closing state of the door according to the detected opening and closing signal. When the detector 240 detects an opening signal or a closing signal of any one of the doors, it sends switch status information to the controller, where the switch status information includes the last two switch statuses of each door, which are the preceding status and the following status, respectively. The controller 220 analyzes the operation behavior of the user on the door according to the received switch state information. And when the received on-off state information shows that the current on-off states of all the box doors are closed states, determining that all the box doors are closed.

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:

it can be seen from the above embodiments that the present application relates to two implementation scenarios for triggering the update of the food material management interface, and one of the scenarios is that, after the user closes the last door in the open state, the RFID tag in the stock room is checked, and the food material management interface is updated according to the checking result. Therefore, after the user stores the food materials into the storage chamber or takes the food materials out of the storage chamber, the food material management interface can immediately respond to updating, so that the user can immediately check the change of the food materials in the storage chamber on the food material management interface, and if the food materials are newly added in the storage chamber, the food materials are reduced, and the like. Secondly, when the confirmation operation input by the user in the food material editing interface is received, a food material icon comprising a distinguishing display characteristic is newly added in the food material management interface according to the latest input food material information. Therefore, after the user finishes editing the tags, the user does not need to manually operate, the user does not need to wait until the user puts the latest editing tags and the associated food materials into the refrigerator, the food material management interface can immediately respond to updating, so that the user can immediately check the food material icons corresponding to the latest editing tags on the food material management interface, and the user experience is improved.
