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

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

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

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

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

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

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

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

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

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

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

In some embodiments, the user may also instruct the instruction for editing the food material information by speaking a preset voice password. For example, the user speaks: "tag editing". When voice data input by a user is received and the content is recognized as 'tag editing', the fact that an input preset voice instruction for triggering the food material information corresponding to the RFID tag to be edited is received is confirmed. At this time, the controller displays a tag scanning interface in response to the instruction, and starts detecting the RFID tag on the tag reading area. And when the RFID label on the label reading area is detected, displaying a food material editing interface.

The user can input food material information in the food material editing interface, and after the controller receives the food material information input by the user, the controller associates the food material information with the RFID tag and stores the association relationship locally.

And if the appointed code segment intercepted from the label code is not the preset code, judging that the label is the predefined label, at the moment, acquiring preset food material information corresponding to the predefined label according to the food material code contained in the label code of the label, displaying a food material editing interface according to the preset food material information corresponding to the label, and prompting a user that the label cannot be marked. The corresponding relation between the food material codes and the preset food material information can be stored in the cloud and preset locally.

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

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

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

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

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

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

It should be noted that in the food material editing interfaces shown in fig. 4-6, the input positions corresponding to the "shelf life" and the "number" are displayed with the measurement units by default. For example, in fig. 4, the measured units of shelf life are shown as "days" and the measured units of quantity are shown without "g". In fig. 5, the measured units of shelf life are shown as "months" and the measured units of quantity are shown as "parts". And in fig. 6, the units of measure of shelf life are shown as "days" and the units of measure of quantity are shown as "catties". When the food material editing interface is displayed, a user can set the measurement units of the shelf life and/or the number of food materials according to the requirement. For example, when the food material management interface shown in fig. 4 is displayed, the user may click on a pull-down control next to a measurement unit to control the display of the measurement unit options.

For example, when the food material editing interface shown in fig. 4 is displayed, the user may click on a pull-down control next to the shelf life measurement unit to control the pop-up of the measurement unit option of shelf life, as shown in fig. 7. After the measurement unit option of the shelf life is popped up, the user can select the measurement unit to be set through click operation, as shown in the example shown in fig. 7, after the user selects "month", the measurement unit option is retracted, and the measurement unit displayed in the food material editing interface is changed from "day" to "month".

In some embodiments, the user may enter food material information through a voice password while displaying the food material editing interface. The voice password can comprise one or more pieces of operation instruction information, such as instruction information of the name of the operation food material, instruction information of the shelf life of the operation food material and instruction information of the quantity of the operation food material. For example, when displaying the food material editing interface, if the user says: the controller can analyze the instruction information for operating the name of the food material and the instruction information for operating the quantity of the food material from the voice command by defining the beef tag of 2 jin. As another example, when displaying the food material editing interface, if the user says: the controller can analyze instruction information for operating the food material shelf life from the voice password. Furthermore, the controller can input the content corresponding to the corresponding item according to the analyzed instruction information and display the content in the food material editing interface without inputting characters by a user. Therefore, user operation can be further reduced, the editing process is quicker, the universality degree of the function can be improved, and old people or children who cannot type can also edit food material information.

In some embodiments, when the controller detects that the user places the RFID tag on the tag reading area, a voice recognition content area is displayed in the food material editing interface, and the receiving and recognizing of the voice password of the user are started, wherein the input prompt and the recognized voice content can be displayed in the voice recognition content area. In some embodiments, the food material editing area and the speech recognition content area may be two different view display areas. The different view display areas may be areas belonging to the same layer, or may be areas belonging to different layers.

Fig. 8 illustrates a food material editing interface including a speech recognition content area according to some embodiments of the present application. As shown in fig. 8, the speech recognition content area 810 is displayed at the uppermost layer of the food material editing interface, and is not overlapped with the food material editing area 820. An input prompt is displayed in the speech recognition content area 810, specifically, a text prompt indicating that the content is "you can say i want to define 2 jin of juicy peaches". When the voice password input by the user is received and the voice content is recognized, the recognized voice content can be displayed in the voice recognition content area.

In some embodiments, the controller receives a voice password input by a user and sends voice password data to the server; the server analyzes the voice password data to obtain corresponding voice content, and generates voice instruction information according to the voice content, wherein the voice instruction information comprises a plurality of fields, one field corresponds to one food input item, the field name is an item name, and the field value is an operation type and/or operation data. The server returns the generated voice instruction information to the controller, and the controller operates the corresponding input items according to the field values of the fields in the voice instruction information and displays the contents of the corresponding input items.

In some embodiments, the voice instruction information includes first instruction information, the first instruction information is used for operating the shelf life of the food material, the first instruction information at least includes first operation data, the first operation data includes a first operand value and a first time unit, the first operand value carrying the first time unit is original voice content directly analyzed from a voice password, and if the voice password input by the user is "i want to define 2 jin beef, the shelf life is 3 months", the first operand value carrying the first time unit is "3 months".

In some embodiments, after the controller obtains the first instruction information for operating the shelf life of the food material by analyzing the input voice password, the controller determines second instruction information according to the first instruction information, wherein the second instruction information includes a target operation type and second operation data, the second operation data includes a second operand value and a second time unit, and the second time unit is one of the preset time units. And then displaying input content corresponding to the quality guarantee period of the food materials in the food material editing interface according to the target operation type and the second operation data.

In the process that the controller generates the second instruction information according to the first instruction information, whether the first time unit is a preset time unit or not is judged at first, and whether the first operand value is an integer or not is judged at the same time. If the first time unit is a preset time unit and the first operand value is an integer, the operand value and its unit in the first instruction information do not need to be processed, but the first time unit is determined as the second time unit and the first operand value is determined as the second operand value. If the first time unit is not the preset time unit or the first operand value is not an integer, the operand value and the unit thereof in the first instruction information need to be processed, specifically, the first operand value is converted into a second operand value in the preset time unit according to a conversion relation between the first time unit and the preset time unit, and the second operand value needs to be guaranteed to be an integer.

In some possible implementations, the preset time unit includes a month and a day. Converting the first operand value to a second operand value in months or days when the first time unit is a year or a month; the first operand value is converted to a second operand value in days when the first unit of time is a week or a day. Specifically, if the first time unit is year and the first operand value is an integer, such as 3 years, the first operand value carrying the first time unit is directly used as the second operand value without processing the first operand value. If the first time unit is year and the first operand value is not an integer, such as 2.5 years, the first operand value is converted to a second operand value in months, i.e., 2.5 x 12 months. If the first time unit is month and the first operand value is an integer, for example, 3 months, the first operand value carrying the first time unit is directly used as the second operand value without processing the first operand value. If the first time unit is month and the first operand value is not an integer, such as 2.5 months, the first operand value is converted to a second operand value in days, i.e., 2.5 x 30 days. If the first time unit is a week (week), since the week is not a preset time unit, the first operand value needs to be converted into a second operand value in days, for example, 3 cycles needs to be converted into 3 × 7 days, regardless of whether the first operand value is an integer. If the first time unit is a day and the first operand value is an integer, it need not be processed. If the first time unit is a day and the first operand value is not an integer, the first operand value is rounded down to a second operand value that is still in days, e.g., 2 days for 2.5 days and 3.4 days for 3 days.

In addition, when the user inputs the food material information by voice control, the input voice password may further include an operation type for operating the shelf life of the food material, and the operation type may include an extending operation, a shortening operation, and a setting operation. It should be understood that if the input voice password includes an operation type supported by the refrigerator, the operation type is naturally included in the first instruction information obtained by parsing the voice password. If the input voice password does not contain the operation type supported by the refrigerator, the operation type is not included in the first instruction information. For example, when the food material editing interface is displayed, if the user says "extend shelf life 3 months", the operation type included in the voice password is an extension operation; if the user says 'shelf life is shortened by 2 months', the operation type contained in the voice password is shortening operation; if the user says "define shelf life 3 months", the operation type contained in the voice password is the setting operation.

Based on the above, in the process that the controller generates the second instruction information according to the first instruction information, if the first instruction information further comprises the operation type, the operation type is determined as the target operation type, and if the operation type is not included in the first instruction information, the preset operation type is determined as the target operation type. As a possible implementation, the preset operation type may be a setting operation. That is, when the operation type is not included in the first instruction information, the setting operation is determined as the target operation type.

When the controller is based on the target operation type and the second operation data, the controller firstly determines display data according to the target operation type and the second operation data, and the display data is composed of a display numerical value and a second time unit. And after the controller obtains the display numerical value counted by the second time unit, the display numerical value carried with the second time unit is used as the input content corresponding to the quality guarantee period of the food material and is displayed in the food material editing interface. Therefore, when the time measuring unit displayed in the food material editing interface is inconsistent with the measuring unit of the quality guarantee period in the user voice command, the operation of the quality guarantee period of the food material can be finished, and the refrigerator can display the time measuring unit according to the user, so that the user experience is improved.

Specifically, when the target operation type is the setting operation, the second operand value is determined as the display value.

Converting the previously stored shelf-life value and the second operand value into a first intermediate value and a second intermediate value in intermediate time units, respectively, when the target operation type is an extension operation; adding the first intermediate value to the second intermediate value to obtain an intermediate sum in intermediate time units; the intermediate sum is converted to a display value in second time units. In order to save the amount of calculation, a preset storage time unit, that is, a unit of a previously stored expiration date value, may be used as an intermediate metering unit. Illustratively, the storage time unit is seconds, the shelf life value of the previous storage is 200000 (seconds), and the second operand value is 3 (days). As can be seen from the foregoing manner of determining the display value, in this example, the second operand value of 3 (days) needs to be converted to 3 × 24 × 60 × 60 (seconds) and then added to the previously stored shelf-life value of 200000, resulting in 261200 (seconds). Finally, 261200 (seconds) was converted to a displayed number in days and rounded down to 5 days.

Or converting the previously stored shelf life value into a value counted in the second time unit according to the conversion relation between the second time unit and the storage time unit, and then adding the value to the second operand value to finally obtain a display value counted in the second time unit.

Converting the previously stored shelf-life value and the second operand value into a first intermediate value and a second intermediate value in intermediate time units, respectively, when the target operation type is a shortening operation; subtracting the first intermediate value from the second intermediate value to obtain an intermediate difference in units of intermediate time; the intermediate difference is converted into a display numerical value in a second time unit. Illustratively, the storage time unit is seconds, the shelf life value of the previous storage is 200000 (seconds), and the second operand value is 3 (days). As can be seen from the foregoing manner of determining the display value, in the case of using the storage time unit (second) as the intermediate time unit, it is necessary to convert the second operand value 3 (day) into 3 × 24 × 60 × 60 (second), and then subtract this from the previously stored expiration date value 200000, to obtain 59200 (second). Finally, 59200 (seconds) was converted to a displayed number in days and rounded down to 0 days.

Or, according to the conversion relation between the second time unit and the storage time unit, converting the previously stored quality guarantee period value into a value counted in the second time unit, and subtracting the second operand value from the previously stored quality guarantee period value to obtain a display value counted in the second time unit.

For example, when the food material editing interface is displayed, in response to a voice password "i want to define 2 jin beef and 3 months of shelf life" input by the user, the content corresponding to the tag name in the food material management interface will be displayed as "beef", the content corresponding to the shelf life of the food material will be displayed as "3 months", and the content corresponding to the number of food materials will be displayed as "2 jin", as shown in fig. 9.

After the content of each input item in the food material editing interface is input, a user can click a confirmation control on the food material editing interface to input confirmation operation. And the controller responds to the received confirmation operation input by the user on the food material editing interface, and correspondingly stores the received food material information input by the user and the identification information of the tag to be edited in the food material information set.

In the above embodiment, when the target operation type is the shortening operation or the extending operation, the second operand value is converted into the second intermediate value in the unit of storage time, so that on one hand, the display value can be calculated conveniently, and on the other hand, the previously stored shelf life value can be updated by directly using the intermediate sum or the intermediate difference in the unit of storage time, so as to complete the shortening operation or the extending operation on the shelf life. And in case that the target operation type is the setting operation, converting the second operand value (or the display value) into a shelf life value in units of storage time and storing the shelf life value in the food material information.

In addition, the controller also cancels the food material editing interface, displays the food material management interface and updates the food material management interface according to the input food material information in response to the confirmation operation. For example, a food material icon generated according to the input food material information is added to the updated food material management interface.

It should be understood that, compared with the food material management interfaces before updating, new food material icons are displayed in some updated food material management interfaces, namely the food material icons corresponding to the newly added food materials; in some updated food material management interfaces, the freshness identifiers of some food material icons are updated because the shelf lives of some food materials are prolonged or shortened.

And then determining second operation data corresponding to the first operation data, wherein the second operation data comprises a second operand value and a second time unit, and the second time unit is a preset time unit. And finally, operating the quality guarantee period of the food material according to the target operation type and the second operation data, and displaying input contents corresponding to the quality guarantee period of the food material in a food material editing interface. Therefore, even if the time unit in the voice password is not consistent with the preset time unit, the operation on the quality guarantee period of the food material can be finished, and the user experience is improved.
