In addition, the power of the antenna of each storage room can ensure that the antenna can recognize the ingredients included in its own compartment, so as to avoid that the false recognition rate will increase when the power is too high, and the ingredients in its own compartment will not be recognized when the power is too small. 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. The larger the space, the higher the power.

In some embodiments, the controller 320 is connected to each RFID detection module, and controls the RFID detection module to recognize the signal of the RFID tag in the storage room.

In some embodiments, the controller is configured to: draw a user interface according to the ingredient information corresponding to each RFID tag in the storage room, and display it on the display screen, such as an ingredient management interface. In the ingredient management interface, the ingredients in the refrigerator are displayed in the form of ingredient icons, pictures and texts. In addition, functional controls can also be drawn in the user interface, such as RFID tag identification controls, ingredient addition controls, etc.

In order to realize the intelligent partition management of the ingredients in the refrigerator, the ingredient management interface can include multiple ingredient display areas and functional controls. One ingredient display area can correspond to one storage room, so that the ingredients in the same storage room can be displayed in the same ingredient display area.

The ingredient icon may be generated according to the pictographic picture of the ingredient, and the freshness indicator of the ingredient is used to indicate the time when the ingredient is put in, the remaining shelf life, and the like. The functional controls in the ingredient management interface include, but are not limited to, controls for triggering RFID tag identification, controls for adding ingredient information, and controls for displaying recipe information.

In practical applications, due to the large detection range of the RFID detection module, it is impossible to accurately determine the storage location of each RFID tag, that is, it is impossible to automatically obtain the storage room where the ingredients identified by the RFID tag are located. The RFID tags of other storage rooms cannot realize the intelligent partition management of ingredients and affect the user experience.

In some embodiments, if it is detected that a newly added RFID tag appears in the refrigerator, the ingredient control corresponding to the ingredient identified by the newly added RFID tag is displayed in a designated area in the ingredient management interface. Partitioned ingredients and corresponding storage rooms, so as to realize intelligent partition management of newly added ingredients.

FIG. 4 is a user interface shown in the present application according to an exemplary embodiment, which is specifically an exemplary ingredient management interface. Referring to Figure 4, the ingredient management interface is divided into left and right display areas; wherein, the left area includes RFID tag identification controls and ingredient display areas corresponding to each ingredient category, such as fruits, vegetables, and each ingredient display area. The corresponding categories of ingredients icons and ingredient names are displayed in the display; the right area includes the recommended recipe controls and the ingredient display areas corresponding to each storage room, such as the refrigerator room, changing room, freezer room, etc. Each ingredient display area displays corresponding ingredient icon and ingredient name. In addition, the right area of the ingredient management interface shown in FIG. 4 also includes a custom area, where the custom area is used to display newly added ingredients in the refrigerator that have not been partitioned and classified by the user. In the ingredient management interface shown in FIG. 4 , all ingredients identified by RFID tags in the refrigerator are displayed.

When the display screen displays the ingredient management interface as shown in Figure 4, the user can click on the custom area to trigger the operation process of partitioning and classifying the ingredients in the custom area.

Exemplarily, in response to the user's click on the custom area, a virtual storage interface as shown in FIG. 5 is displayed. In the virtual storage interface, the information of the ingredients to be stored in the partition and the storage room options that can be allocated are displayed, as well as related information. Function controls, such as "OK", "Cancel", etc. By operating the controls in the virtual storage interface, the user realizes the partitioned storage of the ingredients in the custom area.

It can be seen from the above embodiments that although the above embodiments can realize the partition management of ingredients, the user needs to operate each new ingredient in the refrigerator one by one. The intelligent management of the ingredients in the refrigerator is low, and the user experience is poor. .

Embodiments that can further improve the intelligent management capability of the refrigerator and improve the user experience will be described in detail below.

In some embodiments, the local data includes identification information and corresponding ingredient information of a plurality of RFID tags, which are classified into the first type of RFID according to whether each RFID tag is currently placed in the storage room or has been removed from the storage room A tag and a second type of RFID tag, wherein the first type of RFID tag refers to the RFID tag currently placed in the storage room, and the second RFID tag refers to the RFID tag currently removed from 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 third attribute value of the RFID tag, that is, the third The property values are different. Exemplarily, the third attribute value of the first type of RFID tags is 0, and the third attribute value of the second type of RFID tags is 1.

It should be noted that the function of the above-mentioned third attribute value is to distinguish the first type of RFID tag from the second type of RFID tag. The specific form of the third attribute value is not limited in this application, and it can be the first type of RFID tag and the second type of RFID tag. The different status marks of RFID tags, such as the marked status of the first type of RFID tags is the stored status, the marked status of the second type of RFID tags is the removed status, or the first type of RFID tags and the second type of RFID tags. The different storage paths corresponding to the RFID tags, such as the identification information of the first type of RFID tags are stored in the first table, the identification information of the second type of RFID tags is stored in the second table and so on.

In addition, each RFID tag has a first attribute value, and the first attribute value is used to characterize the storage room pre-associated with the RFID tag. For example, if the first attribute value of an RFID tag=0, it means that the RFID tag has been associated with the refrigerator in advance. The association has been established..., when users use RFID tags to identify ingredients, they should select the corresponding RFID tags according to the storage room where the ingredients should be placed. For example, since "apples" should be placed in the refrigerator, users should The cold room establishes an associated RFID tag to identify the "apple". It should be noted that, in order to facilitate users to distinguish the storage room associated with each RFID tag, the RFID tags associated with different storage rooms can be artificially produced in different colors. For example, a red RFID tag can be used as the RFID tag associated with the refrigerator room. Tags, green RFID tags can be used as RFID tags associated with freezer compartments, etc.

Based on this, the controller of the refrigerator is configured to: obtain food information corresponding to the first type of RFID tags from local data, and obtain a first information set; and then display the food management interface according to the first information set, and the food management interface includes and storage There are ingredient display areas with a similar number of rooms, and each ingredient display area displays ingredient controls generated according to ingredient information, wherein ingredient controls corresponding to RFID tags with the same first attribute value are displayed in the same ingredient display area.

In a specific implementation, the controller may determine the first type of RFID tags according to the third attribute values of all the RFID tags stored locally; obtain the food material information corresponding to the first type of RFID tags according to the identification information of the first type of RFID tags, and obtain the first information gather.

In the above-mentioned embodiment, since the first attribute value of the RFID tag represents the storage room associated with the RFID tag, the food control corresponding to the RFID tag with the same first attribute value is displayed in the same food display area, and the first attribute value is displayed in the same food display area. The ingredient controls corresponding to RFID tags with different values are displayed in different ingredient display areas, that is, the ingredient controls of ingredients in the same storage room are displayed in the same ingredient display area, so as to realize the automatic partitioning process of ingredients, and There is no need for users to operate each new ingredient in the refrigerator one by one, which improves the intelligent management of ingredients in the refrigerator and improves the user experience.

FIG. 6 is an example of an ingredient management interface according to the application. As shown in FIG. 6 , the ingredient management interface includes three ingredient display areas, which are an ingredient display area corresponding to the refrigerating room, and an ingredient display area corresponding to the wide room. An ingredient display area and an ingredient display area corresponding to the cold greenhouse, each ingredient display area displays ingredient controls corresponding to the ingredients in the corresponding storage room.

In some embodiments, the first attribute value of the RFID tag may be an attribute value stored in local data corresponding to the identification information of the RFID tag, and the first attribute value of the RFID tag may be acquired according to the identification information of the RFID tag.

In some other embodiments, the first attribute value of the RFID tag is specifically a code segment of the tag code of the RFID tag, and the tag code of the RFID tag can be identified by the RFID detection module, and according to the composition rule of the tag code, it is possible to parse out the code segment written with the first attribute of the RFID tag. A code segment of an attribute value, thereby obtaining the first attribute value of the RFID tag.

Exemplarily, assuming that the 25th bit of the 28-bit tag code is used to write the first attribute value of the RFID tag, according to the tag code "0123456789012345678901234567", the first attribute value of the RFID tag is "4".

Based on this, the controller of the refrigerator is further configured to: for each acquired first-type RFID tag, acquire the tag code of the first-type RFID tag from local data; and extract the tag code for writing the first-type RFID tag from the tag code The first code segment of the first attribute value of the tag to obtain the first attribute value of the first type of RFID tag; determine the target storage room associated with the first type of RFID tag according to the first attribute value; determine the target food material corresponding to the target storage room Display area; draw the ingredient controls corresponding to the first type of RFID tags in the target ingredient display area.

In some embodiments, each ingredient control includes, in addition to an ingredient icon, an ingredient name, and a freshness identifier, an explicit label identifier to prompt the user which ingredient controls correspond to an ingredient identified by an RFID tag.

As shown in FIG. 7 , the ingredient control includes an ingredient icon 701 , an ingredient name 702 , a freshness identifier 703 and an explicit label identifier 704 . Fig. 8 is a schematic diagram of another food control material shown in an exemplary embodiment of the present application. The difference from the food material control shown in Fig. 7 is that the color of the explicit label identification in Fig. 7 is different from that of the explicit label identification in Fig. 8 .

As mentioned above, in order to facilitate the user to distinguish the storage room associated with each RFID tag, the RFID tag entities associated with different storage rooms may be artificially produced or marked with different colors. Based on this, in some embodiments, the explicit label identification of the RFID tag is drawn in the same color as the color of its label entity, and the explicit label identification of the ingredient controls in the same ingredient display area is drawn as the same color, The explicit label identifiers of the ingredient controls in different ingredient display areas are drawn in different colors, so that the user can select the specified storage room according to the color of the explicit label identifiers of the ingredient controls in the ingredient display area corresponding to the designated storage room. Associated RFID tags to identify the ingredients in the designated pantry.

In some embodiments, each RFID tag further has a second attribute value, and the second attribute value corresponds to a color value in advance to represent the color of the explicit tag identification corresponding to the explicit tag identification, that is, The explicit label identifiers of the ingredient controls corresponding to the RFID tags with the same second attribute value are drawn in the same color, and the explicit label identifiers of the ingredient controls corresponding to the RFID tags with different second attribute values are drawn in different colors. For example, according to the pre-established correspondence between the second attribute value and the color value, if the second attribute value of a certain RFID tag = 0, the color of the explicit label identification representing the RFID tag should be drawn as red. The second attribute value=1, the color that characterizes the explicit tag identification of the RFID tag should be drawn as green and so on.

In some embodiments, the second attribute value characterizes the first attribute value of the RFID tag of the first color characterizes the refrigerator compartment, the second attribute value characterizes the first attribute value of the RFID tag of the second color characterizes the freezer compartment, and the second attribute value characterizes the freezer compartment. The first attribute value of the RFID tag representing the third color represents the changing room. In this way, in the displayed ingredient management interface, the dominant label identifier of the ingredient control in the ingredient display area corresponding to the refrigerating chamber is displayed as the first color, and the freezing chamber corresponds to the first color. The explicit label identifier of the ingredient control in the ingredient display area of the refrigerated greenhouse is displayed as the second color, and the explicit label identifier of the ingredient control in the ingredient display area corresponding to the changing greenhouse is displayed as the third color.

In some embodiments, the second attribute value of the RFID tag may be an attribute value stored in local data corresponding to the identification information of the RFID tag, and the second attribute value of the RFID tag may be acquired according to the identification information of the RFID tag.

In other embodiments, the second attribute value of the RFID tag is specifically a code segment of the tag code of the RFID tag, and the tag code of the RFID tag can be identified by the RFID detection module, and according to the composition rule of the tag code, it can be parsed out that the code of the RFID tag is written. The code segment of the second attribute value, and then the second attribute value of the RFID tag is obtained.

Exemplarily, assuming that the 26th bit of the 28-bit tag code is used to write the second attribute value of the RFID tag, according to the tag code "0123456789012345678901234567", the second attribute value of the RFID tag is "5".

Based on this, the controller of the refrigerator is further configured to: for each first-type RFID tag, cut out a second code segment for writing the second attribute value of the first-type RFID tag from its tag code, so as to obtain The second attribute value of the first type of RFID tag; the target color value corresponding to the second attribute value is determined according to the second attribute value; when the corresponding ingredient control is generated according to the ingredient information corresponding to the first type of RFID tag, according to the target color value The color value draws the explicit label identification of the ingredient control.

In some embodiments, the controller of the refrigerator is further configured to: detect the opening and closing signals of the box doors through a detector connected thereto, and when it is detected that all the box doors are closed (for example, every time the closing signals of the box doors are detected, according to The state of each box door recorded determines whether all box doors are closed, if all box doors are closed, it is deemed that all box doors are closed), and the zeroth information set is obtained, and the zeroth information set includes the latest identification The identification information of all RFID tags in the storage room that arrives; by comparing the zeroth information set and the first information set, the newly removed RFID tag is determined; the third attribute value of the newly removed RFID Labeled as a second type of RFID tag, the second type of RFID tag is an RFID tag that has currently been removed from the storage room.

Wherein, the first information set includes identification information of the first type of RFID tags and corresponding food material information.

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.

It should be noted that, according to the specific form of the third attribute value, the manner of modifying the third attribute value is different, which is not limited in this application.

In some embodiments, the controller of the refrigerator is further configured to: when a first-type RFID tag is newly added, a second-type RFID tag is newly added, or the food material information corresponding to the first-type RFID tag is updated, according to the latest first-type RFID tag The information collection updates the ingredient management interface. Updating the ingredient management interface according to the latest first information set is similar to the specific implementation of displaying the ingredient management interface according to the first information set in the foregoing embodiment, and will not be repeated here.

According to the above embodiments, the embodiments of the present application further provide a method for displaying an ingredient management interface, the method is applied to the refrigerator provided by the above embodiments, and the execution body of the method includes but is not limited to a controller of the refrigerator. FIG. 9 is a flowchart of a method for displaying an ingredient management interface according to an exemplary embodiment of the present application. As shown in FIG. 9 , the method may include:

Step 901: Acquire a first information set, where the first information set includes food material information corresponding to at least one first-type RFID tag, where the first-type RFID tag is the RFID tag currently placed in the storage room, and the RFID tag uses Used to identify ingredients in the pantry.

In some embodiments, the first type of RFID tags is determined according to a third attribute value of all RFID tags stored locally, the third attribute value representing whether the RFID tags are currently placed in the storage room; according to the first type of RFID tags The identification information obtains the food material information corresponding to the first type of RFID tags, and obtains a first information set.

In some embodiments, when it is detected that all box doors are closed, a zeroth information set is obtained, and the zeroth information set includes the identification information of all RFID tags in the newly identified storage room; by comparing the zeroth information set with the first information collection, to determine the latest RFID tag removed; modify the third attribute value of the newly removed RFID tag to mark the newly removed RFID tag as the second type of RFID tag, and the second type of RFID tag is currently removed from the storage room By comparing the zeroth information set with the first information set and the second information set, the newly placed RFID tag is determined, and the second information set is an information set formed by the identification information of the second type of RFID tags stored locally. ; Modify the third attribute value of the newly inserted RFID tag to mark the newly inserted RFID tag as the first type of RFID tag.

In some embodiments, the target color value corresponding to the second attribute value is determined according to the second attribute value of the first type of RFID tag; when drawing the ingredient control corresponding to the first type of RFID tag, the ingredient control is drawn according to the target color value explicit label identification.

It can be seen from the above embodiments that although the above embodiments can realize the partition management of ingredients, the user needs to operate each new ingredient in the refrigerator one by one. The intelligent management of the ingredients in the refrigerator is low, and the user experience is poor. .

In order to further improve the intelligent management capability of the refrigerator and improve the user experience, firstly obtain the switch status (including the open status and the closed status) of the box door by detecting the switch signal of the box door (including the door opening signal and the door closing signal), and then according to the opening and closing status of the box door. The state change determines the target operation box door, that is, the box door operated by the user, determines the target storage room according to the target operation box door, and finally classifies the newly added ingredients in the storage room after this operation into the determined target storage room. It can be seen that, The partition implementation process does not require manual operation by the user, and realizes a fully intelligent management of ingredients.

In some embodiments, the refrigerator further includes a detector for detecting the switch signal of each box door respectively, recording the switch status of the box door according to the detected switch signal, and sending the switch status information to the controller, so that The switch state information includes the last two switch states of each of the box doors.

Exemplarily, by recording the previous state (Oldstate) and the subsequent state (Newstate) of the box door, the change process of the opening and closing state of the box door is recorded, for example, when the opening signal of the box door is detected, the subsequent state of the box door is recorded. For the open state (Newstate=open), the later state (closed state) recorded before the open signal is detected is automatically updated to the previous state, and then, when the closing signal of the box door is detected, the trailing The state is the off state (Newstate=off), and the subsequent state (on state) before the off signal is detected is automatically updated to the previous state.

In some embodiments, when the detector detects an opening signal or a closing signal of any box door, it sends switch status information to the controller, and the switch status information includes the latest two switch statuses of each box door, that is, the aforementioned in the The first state and the latter state.

Exemplarily, the content of each field in the switch state information sent by the detector to the controller is shown in Table 1.

Table 1

In some embodiments, the controller receives the switch state information sent by the detector, and analyzes the user's operation behavior of the box door according to the received switch state information. For the convenience of description, in this application, the box door operated by the user is referred to as the target operation box door, and the target operation box door refers to the box door whose switch state changes. Specifically, if the previous state of the box door is the open state and the latter state is the closed state, it means that the user has performed a complete opening and closing operation for the box door, and the box door is determined as the target operation box door.

For example, according to the content contained in the switch state information exemplarily shown above, it can be determined that the door of the refrigerator compartment is not operated, the door of the changing compartment is opened but not closed, and the freezer compartment is first opened and then closed, so the target operation is determined. The door of the box is a freezer door and a variable temperature chamber door.

In the embodiment of the present application, the detector can specifically detect the switch signal of the box door by detecting the magnetic sensitive switch and the mechanical switch.

In some embodiments, the controller determines the target storage room according to the target operation box door. Specifically, when the number of target operation box doors is one, the controller determines that the storage room corresponding to the target operation box door is the target storage room. When the number of target operation box doors is multiple, the preset virtual storage room is determined as the target storage room, for example, the custom area in the embodiment shown in FIG. 4 .

For example, if it is determined according to the box door state information that the target operation box door is the refrigerating compartment door, then the target storage room is the refrigerating compartment. If it is determined according to the box door state information that the target operation box door includes a refrigerator compartment and a freezer compartment, then the target storage room is a virtual storage room.

In some embodiments, every time the detector detects an opening signal of a box door, it sends switch status information to the controller until it detects the closing signal of the last box door that was opened, and sends the last switch status to the controller information. The controller judges whether all the box doors are closed according to the received switch status information, that is, whether all the box doors are in the closed state. All RFID tags in all storage rooms are used to obtain identification information of the RFID tags corresponding to each food item in the storage room to obtain a first information set.

After acquiring the first information set through the RFID detection module, the controller may compare the first information set with the second information set to determine the ingredients put into and/or taken out of the refrigerator in this operation, wherein the second information The set is an information set generated based on the identification information obtained when it was detected that all the doors were closed last time.

As an example, the zeroth information set containing all RFID identification information obtained when all the doors of the box were detected to be closed in the previous example, the second information set is generated according to the zeroth information set. The identification information of the RFID tag is added to the zeroth information set, and marked as the removed state, to obtain the second information set. It can be seen that the difference between the second information set and the zeroth information set is that the second information set includes identification information of RFID tags that have been put into the refrigerator and have been removed from the refrigerator.

Taking the first information set obtained when it is detected that all box doors are closed this time as an example, a third information set can be generated according to the first information set. Specifically, by comparing the first information set and the second information set, it is determined that this time The RFID tag corresponding to the ingredients removed from the storage room, that is, the RFID tag whose identification information only exists in the second information set, the identification information of the RFID tag removed from the storage room this time is added to the first information set, and its identification information is added to the first information set. Marking the removed state, a third set of information is generated.

In some embodiments, the controller determines the label corresponding to the ingredients put into the refrigerator this time, that is, the target label, by comparing the first information set and the second information set, and displays the management of the ingredients according to the determined target label and the target storage room. interface, in the ingredient management interface, the storage location of the ingredient identified by the target tag is the target storage room. The target storage room is a storage room corresponding to the target operation box door or a preset virtual storage room. When the ingredient management interface is displayed according to the target label and the target storage room, the ingredient information corresponding to the target label is loaded into the ingredient display area corresponding to the target storage room. For example, when the target storage room is a refrigerator room, the ingredient information associated with the target label is loaded (such as cucumbers) are displayed in the food material display area corresponding to the refrigerating room. When the target storage room is a virtual storage room, the food material information associated with the target tag is displayed in the food material display area corresponding to the virtual storage room, as shown in FIG. 4 . Definition area.

In some embodiments, the target label may be a first target label, where the first target label refers to a label whose identification information exists in both the first information set and the second information set and is marked as being removed in the second information set RFID tag, the user puts the ingredients corresponding to the first target tag into the storage room again through this operation.

In some embodiments, the above-mentioned target tag may also be a second target tag, and the second target tag refers to an RFID tag whose tag information exists in the first information set but does not exist in the second information set. The operation puts the ingredients corresponding to the second target label into the storage compartment for the first time.

In some embodiments, the user can perform one-key partitioning of the ingredients whose storage location is the virtual storage room by operating the ingredient management interface, so as to avoid operating each ingredient one by one.

In the specific implementation, when the display screen displays the ingredient management interface, the user can input the first instruction by operating the ingredient management interface, for example, by clicking any position or designated position of the ingredient display area corresponding to the virtual storage room, or, clicking on the menu provided by the ingredient management interface. Specify function controls, etc. The controller receives the first instruction input by the user, displays a virtual storage interface on the upper layer of the ingredient management interface, and displays the ingredients whose storage location is the virtual storage room and the corresponding recommended storage room in the virtual storage interface. The recommended storage room is determined according to the preset corresponding relationship between the ingredients and the storage room.

Exemplarily, FIG. 5 is a user interface shown in this application according to an exemplary embodiment, specifically an exemplary virtual storage interface. As shown in FIG. 5 , in the virtual storage interface, ingredients in the virtual storage room and corresponding recommended storage rooms are displayed.

In some embodiments, a preset correspondence table between the ingredients and the storage room is obtained in advance, and according to the preset correspondence table, the corresponding recommended storage room can be determined according to the information of the ingredients in the virtual storage room. The storage room includes cucumbers, and according to the preset correspondence table, the storage room corresponding to the cucumber is a refrigerating room, and the recommended storage room corresponding to the cucumber is displayed as a refrigerating room in the virtual storage interface.

When the virtual storage interface is displayed on the display screen, the user can input a second instruction by operating the virtual storage interface, for example, by clicking a specified function control displayed in the virtual storage interface (the “OK” control shown in FIG. 5 ). The controller receives the second instruction input by the user, modifies the storage location of the ingredients in the virtual storage room from the virtual storage room to the corresponding recommended storage room, and further implements one-key partitioning of the ingredients in the virtual storage room. After completing the one-click partition operation, the ingredients in the virtual storage room will be displayed in the display area corresponding to the recommended storage room.

In other embodiments, in addition to displaying recommended storage rooms corresponding to the ingredients, other storage room options may also be displayed for the user to select in the virtual storage interface, so as to realize personalized storage of the ingredients.

It can be seen from the above embodiment that whether the user operates the box door is determined by detecting the switch signal of the box door, and when the switch state of the box door changes, the target operation box door is determined according to the switch state of the box door, and the box door is completely closed. After that, the target storage room is determined according to the determined target operation box door, and finally the newly added ingredients in the storage room are classified into the target storage room, which realizes the automatic identification of the storage location of the ingredients, and the partition management process of the ingredients does not require manual operation by the user. , to improve the user experience.

An embodiment of the present application provides a method for managing ingredients. FIG. 10 is a flowchart of a method for managing ingredients according to an exemplary embodiment of the present application. As shown in FIG. 10 , the method may include:

Step 601, after the switch state of at least one box door of the refrigerator changes, determine a target operation box door according to the change of the switch state of the box door, and the target operation box door is that the switch state changes from the open state to the closed state. box door.

When the opening signal or closing signal of the box door is detected, the latest opening and closing state of the box door is recorded, and it is determined that the opening and closing state of the box door has changed. According to the change process of the opening and closing state of the box door, the target operation box door that is operated (opened and/or closed) by the user can be determined, wherein the target operation box door refers to the box door whose switch state changes, for example, from the open state to A box door in a closed state, or a box door that changes from a closed state to an open state.

Step 602: Determine a target storage room according to the target operation box door, where the target storage room is a storage room corresponding to the target operation box door or a preset virtual storage room.

In a specific implementation, when the number of target operation box doors is 1, the storage room corresponding to the target operation box door may be determined as the target storage room; when the number of target operation box doors is greater than 1, the preset virtual storage room may be determined as the target storage room. The target storage room is the storage location of the ingredients put into the refrigerator by the user operating the box door this time.

Step 603: After the switch states of all the box doors are changed to the closed state, acquire a first information set, where the first information set includes identification information of the RFID tag corresponding to each food item in the storage room.

The signal of each RFID tag in the refrigerator is identified by the RFID detection module to acquire the identification information of the RFID tag, and the acquired identification information of each RFID tag forms a first information set.

Step 604, compare the first information set and the second information set, and determine the target label to be put into the storage room, and the second information set is to change to the closed state according to the last detected switch state of all the doors The information collection generated by the identification information obtained later.

The target tag includes a first target tag and a second target tag, and the first target tag refers to an RFID tag whose identification information exists in the first information set and the second information set at the same time and is marked as a removed state in the second information set, It can be understood that the second target label is removed from the refrigerator before this operation, and is put into the refrigerator again through this operation. The second target tag refers to an RFID tag whose identification information only exists in the first information set. It can be understood that the second target tag is an RFID tag that is put into the refrigerator for the first time through this operation.

Step 605 , displaying an ingredient management interface. In the ingredient management interface, the storage location of the ingredient identified by the target label is the target storage room.

FIG. 4 exemplarily shows an ingredient management interface. As shown in FIG. 4 , in the ingredient management interface, each storage compartment corresponds to an ingredient display area for displaying ingredient information in the corresponding storage compartment.

In step 605, an ingredient management interface is displayed according to the target label and the target storage room, and specifically, the ingredient information corresponding to the target label is loaded into the ingredient display area corresponding to the target storage room for display.

For example, the food material information corresponding to one or more target tags is displayed in the food material display area corresponding to the target storage room, and the target storage room may be one of a refrigerator room, a freezer room, etc., or a virtual storage room.

It should be noted that the controller generates an ingredient control in the ingredient management interface according to the ingredient information corresponding to each RFID tag in the storage room, which is used to represent the corresponding ingredient. As can be seen from Fig. 4 and Fig. 17 , the ingredient control can be composed of one or more interface elements such as ingredient icons, ingredient names, and freshness signs of ingredients. The degree mark is used to show the putting time of the ingredients, the remaining shelf life, etc.

In some embodiments, the refrigerator controller determines the ingredient information corresponding to each RFID tag according to the identification information of each RFID tag and the pre-established correspondence between the identification information and the ingredient information. By pre-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 can be realized. The identification information of the RFID tag may be the tag code of the RFID tag identified by the detection module, or may be a code segment in the tag code.

Exemplarily, the pre-established correspondence between the identification information of the RFID tag and the food material information may be as shown in Table 2 below.

In some embodiments, a correspondence table between the identification information of the RFID tag and the ingredient information is established on the side of the refrigerator and stored locally. Specifically, when the ingredient management interface is displayed on the display screen, the user can input an instruction to enter the ingredient information by operating the ingredient management interface. For example, the user clicks the ingredient information entry control provided on the ingredient management interface to instruct the ingredient information entry; when After the controller receives the instruction, it starts to detect the signal of the RFID tag placed in the designated area to obtain the identification information of the RFID tag, and displays the editing interface for associating the RFID tag with the food information. The identification information of the RFID tag, the editing interface is configured to receive the ingredient information input by the user, which may include an input position for inputting the ingredient information; when the controller receives the ingredient information input by the user in the editing interface, it will receive The RFID tag information and the identification information are stored correspondingly, thereby completing and improving the establishment of the corresponding relationship table between the identification information of the RFID tag and the ingredient information.

Exemplarily, the user may click on the RFID tag identification control in the ingredient management interface as shown in FIG. 4 to input an instruction for entering ingredient information. When the controller receives the instruction input by the user, in response to the instruction, a prompt for prompting the user to place the RFID tag in the sensing area is displayed on the upper layer of the ingredient management interface as shown in FIG. 4 (as shown in FIG. 11 ) And start to detect the signal of the RFID tag placed in the sensing area to obtain the identification information of the RFID tag. After the controller acquires the identification information of the RFID tag, an associated interface including the identification information is presented on the display screen.

Fig. 12 is an editing interface shown in this application according to an exemplary embodiment. As shown in Fig. 12, the associated interface displays the identification information "20200005" of the RFID tag, the input position for inputting the name of the food, and the input position for inputting the food. The input location for the category and the Cancel and OK controls.

In the above embodiment, the identification information of the RFID tag is identified by the RFID module and displayed in the editing interface, and the user does not need to manually input the identification information, thereby avoiding input errors and saving user operations. By establishing the corresponding relationship between the RFID tag and the ingredient information, the virtual association between the RFID tag and the ingredient information can be realized, and the corresponding relationship between the RFID tag and the ingredient information can be modified, so that the same RFID tag is successively associated with different ingredients. Corresponding information, improve the flexibility of the use of RFID tags.

In practical applications, the RFID tag put into use will be taken out and put into the refrigerator by the user many times, and for any RFID tag, when it is put into the refrigerator again, it actually identifies the corresponding food or has occurred. Changes, for example, when an RFID tag is taken out, the identified ingredient is "radish", when the RFID tag is put in again, the identified ingredient is "apple", and since the RFID tag is put in , the ingredient control corresponding to the RFID tag displayed in the ingredient management interface is still an ingredient control generated based on information such as "radish", which is easy to cause confusion for users and is not conducive to user experience.

In addition, if a plurality of identical ingredients are stored in the refrigerator, according to the above-mentioned embodiment, a plurality of identical ingredient controls will be displayed in the ingredient management interface, and if the user takes out the first one of the plurality of identical ingredients from the refrigerator After the ingredients are put in again, the user cannot distinguish which of the multiple identical ingredient controls in the ingredient management interface is the ingredient control corresponding to the first ingredient, and the user experience is unfriendly.

Embodiments capable of solving the above problems and improving user experience will be introduced in detail below.

In some embodiments, the local data includes identification information and corresponding ingredient information of a plurality of RFID tags, which are classified into the first type of RFID according to whether each RFID tag is currently placed in the storage room or has been removed from the storage room A tag and a second type of RFID tag, wherein the first type of RFID tag refers to the RFID tag currently placed in the storage room, and the second RFID tag refers to the RFID tag currently removed from 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 second attribute value of the RFID tag, that is, the second type of RFID tag and the second-type RFID tag The property values are different. Exemplarily, the second attribute value of the first type of RFID tags is 0, and the second attribute value of the second type of RFID tags is 1.

It should be noted that the function of the above-mentioned second attribute value is to distinguish the first type of RFID tag from the second type of RFID tag, and the specific form of the second attribute value is not limited in this application, which may be the first type of RFID tag and the second type of RFID tag. The different status marks of RFID tags, such as the marked status of the first type of RFID tags is the stored status, the marked status of the second type of RFID tags is the removed status, or the first type of RFID tags and the second type of RFID tags. The different storage paths corresponding to the RFID tags, such as the identification information of the first type of RFID tags are stored in the first table, the identification information of the second type of RFID tags is stored in the second table and so on.

In addition, each RFID tag has a first attribute value, and the first attribute value of the RFID tag is used to represent whether the RFID tag is an RFID tag that is repeatedly put into the storage room. For example, if the first attribute value of an RFID tag = 0, it indicates that the RFID tag is an RFID tag that is repeatedly placed in the storage room. If the first attribute value of an RFID tag = 1, it indicates that the RFID tag is not a duplicate RFID tag. RFID tags put into the storage compartment. Wherein, the repeatedly inserted RFID tags refer to the RFID tags that are taken out of the refrigerator at the first time and put into the refrigerator at the second time, and the first time is earlier than the second time.

It should be noted that the function of the above-mentioned first attribute value is to distinguish whether the RFID tag is a label that is repeatedly placed in the storage room. Similar to the above-mentioned second attribute value, this application does not specify the specific form of the first attribute value. be limited. The first attribute value can be the state in which the identification information of the RFID tag is marked, for example, the identification information of the repeatedly placed RFID tag is marked as the repeated placement state, and the identification information of the non-repeatedly placed RFID tag is marked as the non-repeated placement. into the state. The first attribute value can also be a different storage path corresponding to the RFID tag. For example, the identification information of the repeatedly placed RFID tags is stored in the first table, and the identification information of the non-repeatedly placed RFID tags is stored in the second table. Form is medium.

Based on this, the controller of the refrigerator is configured to: obtain food information corresponding to the first type of RFID tags from local data, and obtain a first information set; and then display the food management interface according to the first information set, and the food management interface is based on each Each food item control generated by the food item information, wherein, according to the difference of the first attribute value of the RFID tag, the food item control corresponding to the RFID tag is generated into different states.

During specific implementation, the controller may determine the first type of RFID tags according to the second attribute values of all RFID tags stored locally; obtain the food material information corresponding to the first type of RFID tags according to the identification information of the first type of RFID tags, and obtain the first information gather.

In the above embodiment, since the first attribute value of the RFID tag represents whether the RFID tag is a tag that is repeatedly placed in the storage room, the food control corresponding to the RFID tag is generated according to the difference of the first attribute value of the RFID tag as In different states, the user can judge whether the RFID tag corresponding to the ingredient control is a duplicated label according to the state of the ingredient control. Exemplarily, for a certain RFID tag, if the first attribute value of the RFID tag indicates that the RFID tag is an RFID tag that has been placed repeatedly, the food control in the first state is generated according to the food information corresponding to the RFID tag. The first attribute value of the RFID tag indicates that the RFID tag is not an RFID tag that is repeatedly placed, and then the ingredient control in the second state is generated according to the ingredient information corresponding to the RFID tag. In this way, the user can quickly identify which ingredient controls correspond to the repeatedly placed RFID tags according to whether each ingredient control in the ingredient management interface is in the first state or the second state.

In some embodiments, the controller of the refrigerator is further configured to: in the process of generating the ingredient management interface according to the first information set, determine whether the first attribute value of each first-type RFID tag is a predetermined value; for the first attribute The value of the first type of RFID tag with a predetermined value, and according to the food material information corresponding to the RFID tag, an ingredient control containing an explicit identification is generated, and the explicit identification is used to indicate that the RFID tag corresponding to the ingredient control is a repeatedly placed RFID tag ; For a first type of RFID tag whose first attribute value is not a predetermined value, generate an ingredient control that does not contain an explicit identifier according to the ingredient information corresponding to the RFID tag.

It can be seen from these embodiments that whether the food contains an explicit identifier depends on whether the first attribute value of the RFID tag is a predetermined value, and the food control is generated into two states according to whether the first attribute value of the RFID tag is a predetermined value, that is, including the explicit identification. The state when the explicit flag is included and the state when the explicit flag is not included. The user can identify whether the RFID tag corresponding to the ingredient control is repeatedly placed according to whether the ingredient control displayed in the ingredient management interface contains an explicit identifier.

FIG. 13 is a schematic diagram of an ingredient control according to an exemplary illustration of the present application. As shown in FIG. 13 , the ingredient control includes an ingredient icon 701 , an ingredient name 702 , a freshness indicator 703 and an explicit indicator 704 . FIG. 14 is a schematic diagram of another ingredient control shown in an exemplary embodiment of the present application. Different from the ingredient control shown in FIG. 13 , the ingredient control shown in FIG. 14 does not include an explicit identifier 704 .

For repeated RFID tags, the identified ingredients may change before and after. For example, when an RFID tag is taken out, the identified ingredients are "radish" (affixed to the radish). When the RFID tag is put in again , the identified ingredients are "apples" (posted on apples). In this case, neither the food information corresponding to such RFID tags (repeatedly placed RFID tags) stored locally nor the food controls corresponding to such RFID tags displayed in the food management interface are not based on their latest identification. The ingredient information of the ingredients is updated, so it is easy to cause confusion for users, which is not conducive to user experience.

To solve this problem, in some embodiments, the user can operate any ingredient control in the ingredient management interface to view the detailed ingredient information corresponding to the ingredient control; When the control (that is, the ingredient control corresponding to the repeatedly placed RFID tag) is operated, the ingredient details page is not displayed, but a prompt page is displayed to remind the user that the RFID tag corresponding to the ingredient control is the repeatedly placed RFID tag, so as to prompt the user The food information corresponding to the RFID tag is updated in time according to the actual situation.

In addition, a control for triggering the display of the editing interface may also be provided in the above-mentioned prompt page, so as to facilitate the user's operation.

Based on this, the controller of the refrigerator is further configured to: receive a user operation on the target ingredient control from the user, and in response to the user operation, determine whether the first attribute value of the RFID tag corresponding to the operated target ingredient control is a predetermined value; if The first attribute value of the corresponding RFID tag is a predetermined value, and an interface prompt is presented to prompt the user to update the food information corresponding to the RFID tag; if the first attribute value of the corresponding RFID tag is not a predetermined value, the food details are presented page, the ingredient details page displays the ingredient information corresponding to the target ingredient control.

In addition, when the user inputs new ingredient information corresponding to a certain RFID tag by operating the editing interface, the received new ingredient information is used to replace the locally stored original ingredient information to update the ingredient information corresponding to the RFID tag. .

Further, the controller of the refrigerator is further configured to, when the food material information corresponding to the first type of RFID tag is updated, modify the first attribute value of the first type of RFID tag, so as to update the first type of RFID tag with the updated food material information RFID tags marked as first put into storage.

FIG. 15 is an interface prompt, or referred to as a prompt page, shown in this application according to an exemplary embodiment. As shown in Figure 15, the interface prompt is displayed on the upper layer of the ingredient management interface. It reminds the user through the text content that the ingredient (ie the RFID tag) corresponding to the control has been removed from the refrigerator, that is, the ingredient that has been placed repeatedly (ie the RFID tag). ), and asks the user if they need to re-edit the ingredient. The interface prompt shown in FIG. 15 also displays a control for triggering the display of the editing interface (“Yes, go to edit”). When the user operates the control, it will jump to the editing page shown in FIG. 12 , and The identification information of the corresponding RFID tag is displayed on the edit page. Of course, the user can operate the control for rejecting re-editing in the interface shown in Figure 15 (“No need to edit”), when the user operates the Kongjia, the display of the interface prompt will be canceled, and the ingredient details page will be displayed .

In some embodiments, the controller of the refrigerator is further configured to: detect the opening and closing signals of the box doors through a detector connected thereto, and when it is detected that all the box doors are closed (for example, every time the closing signals of the box doors are detected, according to The state of each box door recorded determines whether all box doors are closed, if all box doors are closed, it is deemed that all box doors are closed), and the zeroth information set is obtained, and the zeroth information set includes the latest identification The identification information of all RFID tags in the storage room that arrives; by comparing the zeroth information set and the first information set, determine the newly removed RFID tag; modify the first attribute value and the second attribute value of the newly removed RFID tag to The newly removed RFID tags are marked as the RFID tags repeatedly put into the storage room and the second type of RFID tags, and the second type of RFID tags are the RFID tags currently removed from the storage room. 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.

And, determine the latest RFID tag by comparing the zeroth information set with the first information set and the second information set, and the second information set is an information set formed by the identification information of the second type of RFID tags stored locally; modify the latest RFID tag; The second attribute value of the inserted RFID tag to mark the newly inserted RFID tag as the first type of RFID tag. The RFID tags whose identification information exists both in the zeroth information set and the second information set are the newly inserted RFID tags; the RFID tags whose identification information only exists in the zeroth information set are the newly inserted RFID tags.

Wherein, the first information set includes identification information of the first type of RFID tags and corresponding food material information.

It should be noted that, according to different specific forms of the first attribute value and the second attribute value, the manner of modifying the first attribute value and the second attribute value is different, which is not limited in this application.

According to the above embodiments, the embodiments of the present application further provide a method for displaying an ingredient management interface, the method is applied to the refrigerator provided by the above embodiments, and the execution body of the method includes but is not limited to a controller of the refrigerator. FIG. 16 is a flowchart of a method for displaying an ingredient management interface according to an exemplary embodiment of the present application. As shown in FIG. 16 , the method may include:

Step 101: Acquire a first information set, where the first information set includes food material information corresponding to at least one first-type RFID tag, where the first-type RFID tag is an RFID tag currently placed in the storage room, and the RFID tag is used to identify all the food items. food in the pantry.

In some embodiments, the first type of RFID tags is determined according to second attribute values of all RFID tags stored locally, the second attribute value representing whether the RFID tags are currently placed in the storage room; according to the first type of RFID tags The identification information obtains the food material information corresponding to the first type of RFID tags, and obtains a first information set.

In some embodiments, when it is detected that all box doors are closed, the zeroth information set is obtained, and the zeroth information set includes the identification information of all the RFID tags in the newly identified storage room; by comparing the zeroth information set with the first Information collection, determining the latest RFID tag removed; modifying the first attribute value and the second attribute value of the newly removed RFID tag to mark the newly removed RFID tag as the RFID tag repeatedly put into the storage room and the second type RFID tags, the second type of RFID tags are RFID tags that are currently removed from the storage room. And determine the latest RFID tag by comparing the zeroth information set with the first information set and the second information set, and the second information set is an information set formed by the identification information of the second type of RFID tags stored locally; The second attribute value of the inserted RFID tag is used to mark the newly inserted RFID tag as the first type of RFID tag.

Step 102: Display the ingredient management interface according to the first information set, and the ingredient management interface includes ingredient controls generated according to the information of each ingredient, wherein, according to the difference of the first attribute value of the first type of RFID tag, the first type of RFID The ingredient controls corresponding to the tags are generated in different states, and the first attribute value represents whether the first type of RFID tags are RFID tags that are repeatedly put into the storage room.

In some embodiments, it is determined whether the first attribute value of each first-type RFID tag is a predetermined value; for the first-type RFID tag whose first attribute value is a predetermined value, an explicit identification is generated according to the corresponding ingredient information. Ingredient control, the explicit identification is used to indicate that the RFID tag corresponding to the ingredient control is an RFID tag that is repeatedly placed; for the first type of RFID tag whose first attribute value is not a predetermined value, the generation of the corresponding ingredient information does not contain explicit RFID tags. Identified ingredient controls.

In some embodiments, the method provided by the present application further includes: receiving a user operation on the target ingredient control; in response to the user operation, judging whether the first attribute value of the RFID tag corresponding to the target ingredient control is a predetermined value; if the corresponding RFID The first attribute value of the tag is a predetermined value, and an interface prompt is presented to prompt the user to update the ingredient information corresponding to the RFID tag.

In some embodiments, the method provided by the present application further includes: when the food material information corresponding to the first type of RFID tag is updated, modifying the first attribute value of the first type of RFID tag to update the food material information of the first type The RFID tag is marked as an RFID tag that is first put into the storage room.

In the related art, it is necessary to identify each RFID tag one by one to read the identification information of each RFID tag, and input the information of the ingredients to be associated with the RFID tag one by one, and then store the identified identification information corresponding to the input ingredient information locally, The operation is cumbersome and the user experience is not friendly enough.

Embodiments capable of solving the above problems and improving user experience will be introduced in detail below.

In some embodiments, the controller of the refrigerator is configured to: when it is detected that all the doors of the refrigerator are closed, identify all the RFID tags in the storage room, and obtain the tag code of each RFID tag; determine the RFID tag according to the tag code of the RFID tag Whether the tag is a newly added RFID tag, where the newly added RFID tag refers to an RFID tag that is not associated with the food information; if the RFID tag is a newly added RFID tag, the newly added RFID tag is obtained according to the tag code of the newly added RFID tag For the corresponding preset ingredient information, if the RFID tag is not a newly added RFID tag, obtain the ingredient information associated with the RFID tag according to the tag code of the RFID tag; update the ingredient management interface. In the updated ingredient management interface, each new The ingredient controls corresponding to the RFID tags are generated based on the preset ingredient information corresponding to each newly added RFID tag, and the ingredient controls corresponding to other RFID tags are generated based on the ingredient information associated with other RFID tags. The tags refer to the identified RFID tags other than the newly added RFID tags.

In some embodiments, the controller detects the opening and closing signals of the cabinet doors through a detector connected thereto to monitor the timing of closing of all the cabinet doors. Wherein, detecting that all the box doors are closed means that a closing signal of the box doors is detected and all the box doors are closed when the closing signal is detected. For example, every time the closing signal of the box door is detected, it is determined whether all the box doors are closed according to the recorded state of each box door, and if all the box doors are closed, it is deemed that all box doors are closed.

More specifically, the detector for detecting the switch signal of the box door detects the switch signal of each box door, and records the switch state of each box door according to the detected switch signal, and sends the switch status information to the controller. The state information includes the last two opening and closing states of each door.

Exemplarily, by recording the previous state (Oldstate) and the subsequent state (Newstate) of the box door, the change process of the opening and closing state of the box door is recorded, for example, when the opening signal of the box door is detected, the subsequent state of the box door is recorded. For the open state (Newstate=open), the later state (closed state) recorded before the open signal is detected is automatically updated to the previous state, and then, when the closing signal of the box door is detected, the trailing The state is the off state (Newstate=off), and the subsequent state (on state) before the off signal is detected is automatically updated to the previous state.

Exemplarily, each field in the switch state information sent by the detector to the controller is as shown in Table 1 above.

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 according to the received switch state information. When the controller shows that the following states of all the doors are closed according to the received switch state information, and the preceding state of at least one door is open, it is deemed that all doors are closed.

In the embodiment of the present application, when the controller detects that all box doors are closed, it instructs the RFID detectors connected to it to identify the RFID tags in all the storage rooms, and obtain the tag code of each 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, respectively. Wherein, the first code segment is used to write the first code, and the first code is used as the identification information of the RFID and has uniqueness; the second code segment is used to write the second code, and the second code is a predetermined code or a non-predetermined code. coding. For RFID tags whose second code is a predetermined code, the corresponding food material information can be customized by the user; for RFID tags whose second code is a non-predetermined code, the corresponding preset food material information is stored in the cloud server in advance, and cannot be set by the user. Custom.

In some embodiments, the predetermined code is unique, such as 00; the non-predetermined code is not unique, and there may be more than one, and one non-predetermined code corresponds to one kind of food item information.

Exemplarily, a tag coding structure of an RFID tag is shown in Table 3.

table 3

It should be noted that, according to different requirements, the label code of the RFID tag can also include more code segments, such as the third code segment, which is used to write the manufacturer's identification of the RFID tag, and the fourth code segment, which is used as a label. Encoded reserved bits to improve scalability of RFID tags. In other embodiments, the manufacturer identification of the RFID tag may also be included in the first code segment, which will not be repeated here.

Exemplarily, the corresponding relationship between the second code (non-predetermined code) and the food material information may be as shown in Table 4.

Table 4

RFID second code	food name	food category
01	radish	Vegetables
02	carrot	Vegetables
03	lotus root	Vegetables
...	...	...

In some embodiments, at least two code segments included in the label code of the RFID tag conform to a preset composition rule, and after acquiring the label code, the controller intercepts the first code segment and/or the second code segment according to the preset composition rule segment etc. to obtain the first code and/or the second code, thereby saving the process of parsing long code information and improving processing efficiency.

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

Based on this, the controller of the refrigerator is further configured to: obtain the first code written in the first code segment from the identified tag code of the RFID tag; find out whether the first code of the RFID tag exists in the local information set, the The local information set includes the first code of the RFID tag that has been associated with the food information; if the first code of the RFID tag does not exist in the local information set, it is determined that the RFID tag is a newly added RFID tag; The first code of the RFID tag determines that the RFID tag is not a newly added RFID tag.

For an RFID tag that has been associated with food material information, its unique identification information (ie, the first code) and its associated food material information are correspondingly stored in the local information set. It should be noted that other information may also be stored in the local information set, such as the complete tag code or the second code of the RFID tag, a status mark, an attribute identifier, and an attribute value.

In some embodiments, the controller is further configured to: if the identified RFID tag is a newly added RFID tag, that is, an RFID tag not associated with food material information, write in the second code segment obtained in the RFID tag the second code of the RFID tag; determine whether the second code of the RFID tag is a predetermined code; if the second code of the RFID tag is a predetermined code, obtain the preset default filling information as the preset food material information of the RFID tag; If the second code of the RFID tag is not the predetermined code, according to the second code of the RFID tag, the preset food material information corresponding to the RFID tag is obtained from the preset correspondence between the second code and the food material information.

In some embodiments, after acquiring the preset ingredient information corresponding to the newly added RFID tag, the tag code (complete tag code or the first code and the second code) of the newly added RFID tag is corresponding to the corresponding preset ingredient information Saved in the local information collection.

In the above embodiment, the default ingredient information may be ingredient information composed of specified character strings, such as "Ingredient Name: Undefined", "Ingredient Category: Undefined", "Shelf Life: Undefined/60 Days" and the like. The default ingredient information is used to generate a temporary ingredient control corresponding to the RFID tag in the ingredient management interface before the RFID tag is not associated with the ingredient information, so as to instruct the user to edit the ingredients of the RFID tag by operating the temporary ingredient control The default ingredient information is also used to occupy the data position in the local information set, that is, occupy the position to which the ingredient information associated with the RFID tag belongs, so that after the user enters the ingredient information associated with the RFID tag, it is associated with the RFID tag. replaced with the ingredient information.

FIG. 18 is another ingredient management interface shown in the present application according to an exemplary embodiment. As shown in FIG. 18 , compared with the ingredient management interface shown in FIG. 17 , multiple ingredient controls are newly added to the interface, that is, multiple ingredient controls are added to the interface. The ingredient controls corresponding to the newly added ingredient labels specifically include ingredient controls 501, 502 and 503 generated according to default filling information, and ingredient controls 504 and 505 generated according to preset ingredient information. As shown in Figure 18, the ingredient control generated according to the default filling information is the same as other ingredient controls in that it also includes ingredient icons, ingredient names, etc., and is different from other ingredient controls in that it uses "undefined" as the ingredient name , Take the picture file containing the word "undecided" as the ingredient icon, which clearly shows that the corresponding RFID tag has not yet been associated with the ingredient information, that is, the undefined tag, or the unedited tag, thus effectively reminding the user in time Edit these RFID tags.

It can be seen from the above embodiment that, by designing the composition of the tag code, each RFID tag is already corresponding to the specified food material information before being put into use by the user; on this basis, on the user side, whenever all box doors are detected When it is closed, it will identify the RFID tags in the storage room, and determine whether there are new RFID tags that are not associated with the food information, so as to realize the batch identification of multiple new RFID tags, without the need to identify each new RFID one by one. Labels; for newly added RFID tags, the corresponding preset ingredient information is obtained according to its tag code, and the preset ingredient information is used as the ingredient information associated with the newly added RFID tags to be saved. It can be seen that each newly added RFID tag is realized through background processing. The process of associating with the corresponding ingredient information does not require the user to input the ingredient information to be associated with the newly added RFID tag one by one, making the user experience more friendly; the ingredient management interface is updated according to the preset ingredient information, so that the user can sense the new items in the refrigerator in time. Added RFID tags and ingredients to further enhance the user experience.

In practical applications, the RFID tag used by the user is an editable tag, that is, whether the associated ingredient information can be customized by the user, such as an RFID tag whose second code is a predetermined code. As mentioned above, if the second code of the newly added RFID tag is a predetermined code, the default filling information is obtained as its preset ingredient information, which is used to generate a temporary ingredient control in the ingredient management interface to prompt the user to add such a new type in time. The RFID tag is edited and occupies the data position in the local information collection. In order to facilitate the user to quickly enter the editing interface, the user can operate the food control corresponding to the newly added RFID tag to trigger a jump to the interface for editing the corresponding newly added RFID tag.

Specifically, the controller of the refrigerator is further configured to: receive a user operation on the target ingredient control, such as a click operation; in response to the user operation, determine whether the operated target ingredient control is an ingredient control generated according to the default filling information; If the target ingredient control is an ingredient control generated according to the default filling information, the ingredient editing interface is displayed, and the ingredient editing interface is configured to receive the target ingredient information input by the user; if the target ingredient control is not an ingredient control generated according to the default filling information, then The ingredient details interface is displayed, and the ingredient information corresponding to the target ingredient controls is displayed on the ingredient details interface.

As an implementation manner, the controller may determine whether the target ingredient control is an ingredient control generated according to default filling information according to whether the second code of the RFID tag corresponding to the target ingredient control is a predetermined code. If the second code of the RFID tag corresponding to the target ingredient control is the predetermined code, it is determined that the target ingredient control is an ingredient control generated according to the default filling information; if the second code of the RFID tag corresponding to the target ingredient control is not the predetermined code, it is determined that the target Ingredient controls are not generated based on default fill information.

The ingredient editing interface shown in the present application according to the exemplary embodiment may be the interface shown in FIG. 19 . As shown in Figure 19, as shown in Figure 19, the editing interface displays the identification information "20200005" of the RFID tag, the input position for inputting the name of the ingredient, the input position for inputting the category of the ingredient, and the "Cancel" control and "" OK" control.

In some embodiments, the controller of the refrigerator is further configured to: receive the target ingredient information input by the user in the ingredient editing interface; use the target ingredient information to replace the default corresponding to the tag code of the RFID corresponding to the target ingredient control in the local information set Fill in the information.

It can be seen from the above embodiment that whenever it is detected that all the doors are closed, the RFID tags in the storage room are identified, and it is judged whether there is a new RFID tag that is not associated with the food information. With custom new RFID tags and user-defined new RFID tags, for user-defined new RFID tags, the default filling information is used as its corresponding preset ingredient information to generate its corresponding ingredients Controls, so that users can sense the new RFID tags that are not defined in the refrigerator in time, and users can quickly enter the corresponding editing interface by operating the corresponding ingredient controls. The operation is simple and there is no need to identify the RFID tags separately. A friendlier experience.

According to the above embodiments, the embodiments of the present application further provide a method for managing ingredients. The method is applied to the refrigerator provided by the above embodiments, and the execution body of the method includes but is not limited to a controller of the refrigerator. FIG. 20 is a flowchart of a method for displaying an ingredient management interface according to an exemplary embodiment of the present application. As shown in FIG. 20 , the method may include:

Step 701, when it is detected that all the doors are closed, identify the RFID tags in the storage room of the refrigerator, and obtain a tag code of each of the RFID tags, where the RFID tags are used to identify the ingredients in the storage room.

Step 702, according to the label code of the RFID tag, determine whether the RFID tag is a newly added RFID tag, and the newly added RFID tag is an RFID tag not associated with food information; if so, go to step 703, if not, execute Step 704.

In some embodiments, the first code written in the first code segment is obtained from the tag code; it is searched whether the first code of the RFID tag exists in the local information set, where the local information set includes the RFID of the associated food item information The first code of the tag; if the first code of the RFID tag does not exist in the local information set, it is determined that the RFID tag is a newly added RFID tag; if the first code of the RFID tag exists in the local information set, it is determined that the RFID tag is The tags are not new RFID tags.

Step 703: If the RFID tag is the newly added RFID tag, obtain preset food material information corresponding to the newly added RFID tag according to the tag code of the newly added RFID tag.

In some embodiments, the second code written in the second code segment is obtained from the tag code of the newly added RFID tag; it is determined whether the second code of the newly added RFID tag is a predetermined code; If the second code is a predetermined code, the preset default filling information is obtained as the preset food material information of the newly added RFID tag; if the second code of the newly added RFID tag is not the predetermined code, then the second code of the newly added RFID encoding, and obtains preset ingredient information corresponding to the newly added RFID tag from the preset corresponding relationship between the second code and the ingredient information.

In some embodiments, after obtaining the preset ingredient information corresponding to the newly added RFID tag according to the tag code of the newly added RFID tag, the tag code of the newly added RFID tag and its corresponding preset ingredient information are stored in the local information set correspondingly .

Step 704, if the RFID tag is not the newly added RFID tag, obtain the food material information associated with the RFID tag according to the tag code of the RFID tag.

Step 705: Update the ingredient management interface including ingredient controls generated according to the ingredient information associated with the RFID tag. In the updated ingredient management interface, the ingredient control corresponding to the newly added RFID tag is based on the newly added RFID tag. The preset ingredient information corresponding to the tag is generated, the ingredient controls corresponding to other RFID tags are generated according to the ingredient information associated with the other RFID tags, and the other RFID tags refer to the identified RFID tags other than the newly added RFID tags.

In some embodiments, the ingredient management method provided by the present application further includes: receiving a user operation on a target ingredient control; in response to the user operation, judging whether the target ingredient control is an ingredient control generated according to default filling information; if the target ingredient control is For the ingredient control generated according to the default filling information, the ingredient editing interface is displayed, and the ingredient editing interface is configured to receive the target ingredient information input by the user; if the target ingredient control is not an ingredient control generated according to the default filling information, the ingredient details interface is displayed. The ingredient details interface displays the ingredient information corresponding to the target ingredient control.

In the specific implementation, the second code of the RFID tag corresponding to the target ingredient control is obtained; it is determined whether the second code of the RFID tag corresponding to the target ingredient control is a predetermined code; if the second code of the RFID tag corresponding to the target ingredient control is a predetermined code, Then it is determined that the target ingredient control is an ingredient control generated according to the default filling information; if the second code of the RFID tag corresponding to the target ingredient control is not a predetermined code, it is determined that the target ingredient control is not an ingredient control generated according to the default filling information.

In some embodiments, in order to realize the intelligent management of the ingredients, RFID tags are used to identify the ingredients in the storage room. Specifically, the identification information of the RFID tags, such as the tag code written in the RFID tags, is pre-obtained, and the RFID tags are established. The corresponding relationship between the identification information of the RFID tag and the specified food material information realizes the association between the RFID tag and the food material; after sticking the RFID tag on the food material, put the food material into the refrigerator, and the refrigerator obtains the identification information of the RFID tag by detecting the signal of the RFID tag. In the case of obtaining the identification information, through the pre-established unique correspondence between the identification information of the RFID tag and the ingredient information, the ingredient information corresponding to the RFID tag can be determined, and by displaying the ingredient information on the user interface, the user can pass The user interface knows the ingredients in the refrigerator, and can perform management operations on the ingredients by operating the user interface.

In some embodiments, an RFID detection module is provided in each storage room, and the RFID detection module is used for transmitting wireless signals in the corresponding storage room and receiving signals of RFID tags in the storage room, so as to obtain identification information of the RFID tags.

In some embodiments, the RFID detection module may specifically be an antenna. The power of the antennas provided in different storage compartments may be different. In addition, the power of the antenna of each storage room can ensure that the antenna can recognize the ingredients included in its own compartment, so as to avoid that the false recognition rate will increase when the power is too high, and the ingredients in its own compartment will not be recognized when the power is too small. 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. The larger the space, the higher the power.

In some embodiments, the refrigerator may further include an RFID processing module, which is respectively connected with each RFID detection module, and is used for controlling the RFID detection module to transmit wireless signals and to receive the RFID tag signal fed back by the RFID detection module.

In some embodiments, the controller is connected to the RFID detection module, controls the RFID detection module to identify the signal of the RFID tag in the storage room, and obtains the identification information of each RFID tag and the corresponding food material information, and the food material information includes the identification used to indicate the type of the food material , by displaying the information of these ingredients on the display screen, in this way, the user can know which ingredients are in the freezing chamber.

In some embodiments, the ingredient information further includes a shelf life of the ingredient. The freshness of the ingredients can be monitored according to the shelf life of the ingredients and the recorded time the user puts the ingredients in. By marking the freshness of each ingredient in the ingredient management interface, the user is prompted whether the ingredient has expired, the time until expiration, and the expiration time.

In the related art, after the user puts the ingredients into the storage room, he needs to manually set the time for each ingredient by operating the user interface displayed on the display screen of the refrigerator. The operation steps are cumbersome and the user experience is poor.

In order to improve the intelligent management capability of the refrigerator for ingredients and improve the user experience, the present application provides a refrigerator, the controller of which detects the switch signal of the door, and when it is detected that all the doors are closed, it indicates the RFID connected to it. The detection module identifies the RFID tags in all storage rooms to obtain the identification information of each RFID tag, and obtains the first information set, and determines the target label put into the storage room by comparing the first information set and the second information set, and Determine the target insertion time corresponding to the target label according to the current time, and use the target insertion time to update the insertion time of the ingredients corresponding to the target label. Furthermore, the user does not need to manually set the insertion time of each ingredient, which can provide user experience And can guarantee the accuracy of the obtained time.

Wherein, the second information set is an information set generated according to the identification information obtained when it was detected that all box doors were closed last time.

Take the zeroth information set including all RFID identification information obtained when it is detected that all box doors are closed last time as an example, and the second information set is generated according to the zeroth information set. Specifically, the identification information and removal information of the RFID tags corresponding to the ingredients removed from the refrigerator last time are added to the zeroth information set to obtain the second information set, where the removal information includes the marked removal status and removal status of the removed RFID tags. time. It can be seen that the difference between the second information set and the zeroth information set is that the second information set includes identification information and removal information of the RFID tags that have been put into the refrigerator and have been removed from the refrigerator.

Taking the first information set obtained when it is detected that all box doors are closed this time as an example, the third information set can be generated according to the first information set. Specifically, by comparing the first information set and the second information set, the RFID tags corresponding to the ingredients removed from the storage room this time, that is, the RFID tags whose identification information only exists in the second information set, are determined. The identification information and removal information of the RFID tag in the storage room are added to the first information set, and a third information set is generated, wherein the removal information of the RFID tag removed from the storage room this time includes the marked removal state of the RFID tag and according to The move-out time determined by the current time.

In some embodiments, the refrigerator further includes a detector for detecting the switch signal of each box door respectively, recording the switch state of the box door according to the detected switch signal, and sending the switch status information to the controller.

In some embodiments, when the detector detects an opening signal or a closing signal of any box door, the latest switch state information is sent to the controller. The controller receives the switch state information sent by the detector, and analyzes the user's operation behavior of the box door according to the received switch state information. When the received switch state information shows that the current switch states of all the doors are closed, it is determined that all the doors are closed.

In the embodiment of the present application, the detector can specifically detect the switch signal of the box door by detecting the magnetic sensitive switch and the mechanical switch.

In some embodiments, the above-mentioned target tag includes a first target tag, and the first target tag refers to an RFID tag whose identification information only exists in the first information set. It can be understood that, in this operation, the user puts the ingredients identified by the first target label into the storage compartment for the first time. For the first target tag, the corresponding target insertion time is determined as the current time.

In some scenarios, the user may take out an ingredient identified by an RFID tag and put it back into the refrigerator soon after. Update, the wrong put time will be recorded.

In order to avoid recording an erroneous insertion time when the ingredients put in this operation are the same batch of ingredients that the user has taken out and put in again shortly after, in other embodiments, the controller compares the first information set with the The second information set determines whether there is a second target tag, where the second target tag refers to an RFID tag whose identification information exists in both the first information set and the second information set and is marked as a removed state in the second information set. It should be noted that the second information set also includes the move-out time corresponding to the second target tag.

When determining the target insertion time corresponding to the second target tag according to the current time, first determine that the time difference between the current time and the removal time corresponding to the second target tag is greater than the preset threshold, if the current time and the removal time corresponding to the second target tag The time difference between the times is greater than the preset threshold, then it is determined that the target insertion time corresponding to the second target tag is the current time; if the time difference between the current time and the removal time corresponding to the second target tag is not greater than the preset threshold, it is determined that the first The target insertion time corresponding to the second target label is the last insertion time. Exemplarily, the preset threshold may be 2 hours.

In some embodiments, the corresponding relationship between the RFID tag and the food is pre-established, specifically the corresponding relationship between the identification information of the RFID tag and the food information, the controller identifies the identification information of the RFID tag through the RFID detection module, and then according to the identification information of the RFID tag Find the food information corresponding to the RFID tag from the aforementioned correspondence.

In some embodiments, the user can perform an update operation on the corresponding relationship between the RFID tag and the food item, such as adding new corresponding information, or modifying the food item information corresponding to a certain RFID tag. Among them, modifying the food material information corresponding to a certain RFID tag can make the same RFID tag used to identify different food materials successively, which can improve the flexibility of using the RFID tag.

In some embodiments, the corresponding relationship between the RFID tag and the food item is also referred to as an association relationship. The ingredient information corresponding to the RFID tag is the ingredient information associated with the RFID tag.

In some scenarios, after a user removes an RFID tag out of the refrigerator, the associated ingredient information is modified. When the user puts the modified RFID tag into the refrigerator again, since the corresponding food information before and after the RFID tag is different, if the insertion time corresponding to the RFID tag is not updated, the wrong insertion time will be recorded.

For the above scenario, in order to avoid recording the wrong insertion time due to the change of the food information corresponding to the RFID tag, first, after modifying the food information corresponding to the RFID tag, add a re-association status mark to the identification information of the RFID tag to It indicates that the food information currently corresponding to the RFID tag is different from the food information corresponding to the past. Secondly, when acquiring the first information set, the controller acquires the identification information of each RFID tag in the storage room, wherein, when the food information currently corresponding to the identification information is different from the food information corresponding to the past, the identification information carries The flag of the re-association state, that is, the re-association state is used to indicate that the information of the food material currently associated with the RFID tag is different from the information of the food material that was associated last time, and the first information set is obtained. Furthermore, the controller can determine whether the corresponding food material information before and after each RFID tag is different by judging whether the identification information of each RFID tag is marked with a re-association state. Then, when comparing the first information set and the second information set to determine the target label, traverse and determine whether each identification information in the first information set is marked as a re-associated state, and determine whether the identification information is in the first information set and the second information set. The RFID tags that exist simultaneously in the information set and are marked as re-associated in the first information set are the third target tags. For the third target tag, it is determined that the current time is the target insertion time corresponding to the third target time.

It can be seen from the above example that when the user puts the RFID tag associated with the new ingredient information into the refrigerator again, the insertion time of the ingredient identified by the RFID tag will be updated according to the current time, which can avoid recording the wrong storage. It can improve the accuracy of the refrigerator's automatic acquisition of the time when the ingredients are put in.
