Each food material icon comprises a food material picture, a food material name and a freshness explicit identification. Wherein, the explicit indication of the freshness of the food materials 1 and 12 is the word "expired" displayed on the food material picture, which indicates that the freshness grades of the food materials 1 and 12 are "expired"; the freshness explicit marks of the food materials 4 and 6 are character marks and progress bars which are displayed below food material pictures and have the content of '2 days left', the progress of the progress bars represents the remaining time or the ratio of the remaining time to the quality guarantee period, and the remaining two days of the food materials 4 and 6 are expired, namely the food materials are quickly expired; the freshness of the other food materials is marked as a progress bar, and the progress of the progress bar represents the remaining time or the ratio of the remaining time to the quality guarantee period.

In some embodiments, the user can input the tag editing instruction by operating the tag editing control in the food material management interface. And the food material management application responds to the input label editing instruction and prompts a user to place the label to be edited in the label reading area. The user places the label to be edited into the label reading area, and the antenna on the label reading area scans the label information of the label to be edited. And the food material management application acquires the label information scanned by the antenna and displays a label editing interface. In the label editing interface, the user can input food material information for associating with the label to be edited, including but not limited to food material name, shelf life, production date, quantity (weight), and the like. After the input is completed, the food material management application receives the food material information input by the user, and establishes an association relationship between the food material information and the tag identifier of the tag, for example, the tag identifier and the food material information are correspondingly stored in a local food material information set.

In some embodiments, the controller 220 detects the opening and closing signal of each door through the detector 240, records the opening and closing state of the door according to the detected opening and closing signal, and analyzes the operation behavior of the user on the door according to the opening and closing state information. When the last opened box door is monitored to be closed, detecting the RFID label in the storage room to acquire the identification information of the RFID label; and updating the storage state of the food material information in the local food material information set according to the identification information of the RFID tag in the storage room. Specifically, the identification information of the RFID tag in the storage room is compared with the identification information in the local food material information set, and the latest moved-out tag and the latest put-in tag are determined; and marking the storage state corresponding to the latest moved-out label as a moved-out state, and marking the storage state corresponding to the latest put-in label as a put-in state. Therefore, the storage state of the food material information in the local food material information set can be updated in time according to the existing food materials in the refrigerator.

In other embodiments, a user may input a food material adding instruction by operating a food material adding control in the food material management interface. The food material management application responds to a food material adding instruction input by a user, and displays a food material library interface, wherein a large number of selectable food material icons are displayed in the food material library interface, and each food material icon corresponds to food material information. The user can select the food to be added by inputting the selection operation of a certain food icon, on one hand, the selected food icon can be added into the food management interface, on the other hand, the food information corresponding to the selected food icon can be added into the local food information set, and the local food information set is marked as the putting-in state.

The process of adding food materials by inputting the food material adding instruction is at least suitable for the following scenes: after a user stores a real food material (such as apple) in a refrigerator, the food material adding control in the food material management interface is operated to trigger and display the food material library interface, a food material icon (such as an apple icon) corresponding to the real food material (such as apple) is selected in the food material library interface, the selected food material icon is added into the food material management interface, and meanwhile, food material information related to the food material icon is added into a local food material information set. Therefore, the RFID label does not need to be pasted on the real food material, the corresponding food material information can be added into the local food material information set, and the corresponding food material icon can be displayed in the food material management interface, so that the intelligent management of the food material in the refrigerator is realized.

In some implementations, the food library interface includes a tag switching bar and a content area, where the tag switching bar includes multiple tag controls, and when different tag controls are selected, food icons in different ranges are displayed in the content area. For example, when different label controls are selected, food material icons for different categories of food materials are displayed in the content area. Therefore, a user can select the label control corresponding to the category according to the category of the food to be added so as to trigger the food material icons corresponding to the category to be displayed in the content area, and then select the food material icon of the food to be added from the food material icons displayed in the content area.

Fig. 4 illustrates a food material library interface in some exemplary embodiments of the present application. As shown in fig. 4, the food material library interface includes a tag switching bar 410 and a content area 420, the tag switching bar 410 includes a plurality of tag controls, which are respectively "all" 411, "fruit" 412, "vegetables" 413, "meat" 414, "drinks" 415, "aquatic product" 416, "other" 417 and "custom food material" 418, wherein the tag control "fruit" is in a selected state, so that food material icons of a plurality of fruits, which are respectively "apple", "orange", "banana", "watermelon", "mango", "durian", "juicy peach" and "pineapple" … …, are displayed in the content area 420.

In some embodiments, the user can select the food material icon in the food material library interface through a single-point or long-press operation. And the food material management application responds to the selection operation of the user on the food material icons in the food material library interface, directly adds the food material information corresponding to the food material icon selected by the user into the local food material information set, and marks the food material information set as a storage state. In some embodiments, the refrigerator controller executes the following steps shown in fig. 5 periodically by running the food material management application, that is, at preset time intervals, the following steps shown in fig. 5 are executed, where the preset time intervals are preset reminding periods. As shown in fig. 5:

s501, determining target food materials, wherein the target food materials at least comprise food materials with freshness meeting preset reminding conditions, which are determined according to time related information corresponding to the existing food materials in the storage room.

In some embodiments, the preset reminding condition is "expired", that is, the target food material is an expired food material. In other embodiments, the preset reminding conditions are "expired" and "fast expiration", that is, the target food materials include expired food materials and fast expired food materials.

In some embodiments, the target food material further includes a food material corresponding to a name of the food material included in the unread history reminding message. For the convenience of distinguishing, the target food material determined according to the time-related information corresponding to the existing food materials in the storage room may be referred to as a first expired food material, and the expired food material determined according to the unread history reminding message may be referred to as a second expired food material.

In some embodiments, the first expired food material is an expired food material newly generated in the storage room, for example, an expired food material generated in the last reminding period. Therefore, the user trouble caused by repeated reminding of the same overdue food material can be avoided. Wherein the overdue food materials in the existing food materials in the storage room at least comprise first overdue food materials.

In some embodiments, the food material information in the local food material information set has a reminding state identifier, and the reminding state identifier is divided into a first identifier and a second identifier. The first identification is a reminding state identification which is default for each food material information. After the food material management application generates a reminding message according to a certain overdue food material, the reminding state identification of the food material information of the overdue food material is changed from a first identification to a second identification in a local food material information set, namely, the food material marked by the first identification is the food material which is not reminded, and the food material marked by the second identification is the reminded food material. Based on this, as an implementation manner of S501, firstly, the expired food materials in the existing food materials are determined according to the time-related information or freshness identification of the existing food materials in the storage room; and then determining the expired food materials with the reminding state identification as the first expired food materials. That is, the first expired food material determined in S501 refers to an expired food material of which the reminding state identifier is the first identifier, in all the expired food materials, that is, an expired food material that has not been reminded.

In addition, since the food material management application periodically executes S501-S503 to remind the user of the expired food material in the refrigerator, the expired food material with the expired duration longer than the reminding period should be the reminded food material, and the expired food material with the expired duration shorter than or equal to the reminding period should be the reminded food material. Based on this, as another implementation manner of S501, at first, the expired food materials in the existing food materials and the expiration duration of each expired food material are determined according to the time-related information or freshness identifier of the existing food materials in the storage room; and then determining the expired food materials with the expiration duration less than or equal to the reminding period as first expired food materials. Wherein, the expiration time is the current time-the expiration time.

In the above embodiment, the food material management application first reads the food material information of the existing food material from the local food material information set, for example, reads the food material information with the access state being the put-in state. And then determining overdue food materials in the existing food materials according to the time-related information in the food material information of the existing food materials, wherein the overdue food materials are food materials with the overdue time being earlier than the current time. In other implementations, the food material management application first reads the food material information of the existing food material from the local food material information set. And then determining overdue food materials in the existing food materials according to the freshness identifiers in the food material information of the existing food materials, wherein the overdue food materials are food materials with the freshness identifiers of being overdue. For the calculation method of the expiration time and the marking method of the freshness indicator, reference may be made to the foregoing embodiments, which are not described herein again.

In some embodiments, the second expired food material is the food material indicated by the unread reminder message before the preset time intercept point, and the food material indicated by the unread reminder message is the food material name contained in the unread reminder message or the food material corresponding to the food material ID. The preset time intercept point is a time point which is earlier than the current time point by a preset time interval. For example, if the current time point is 24/00/2021 and the predetermined time interval is 3 days, then the predetermined time cut-off point is 21/8/00/2021. It is noted that in the implementation case where the preset time interval is 0, the second expired material includes the expired material indicated by all the unread alert messages in the notification application. Based on this, as an implementation manner of S501, an unread history reminding message before a preset time intercept point in the notification application is obtained, where the preset time intercept point is a time point earlier than a preset time interval of the current time point; and determining the target food material indicated by the history reminding message according to the food material name contained in the history reminding message.

The notification application may be a system application installed on the refrigerator and independent of the food material management application, or may be a functional module integrated in the food material management application. The notification application is used for receiving notification messages generated in the system, reminding messages or notification messages sent by other applications, and displaying the received notification messages or reminding messages in the user interface. For example, an alert message sent by the food material management application is received, and the alert message is displayed in the user interface.

In some embodiments, all expired food materials in the storage room are determined as target food materials.

S502, generating a reminding message according to the target food material, wherein the reminding message comprises the food material name of the target food material.

In some embodiments, a reminding message is generated according to the first expired food material and/or the second expired food material, and the generated reminding message includes the food material name of the first expired food material and/or the second expired food material.

Therefore, according to the embodiment of generating the reminding message according to the first overdue food material, the reminding can be performed only once for each overdue food material, and the trouble brought to the user by the repeated reminding strategies is avoided. And after a reminding message is generated according to the first overdue food material, the reminding state identifier corresponding to the first overdue food material is changed from the first identifier to the second identifier.

In addition, due to the limitation of the use scene of the refrigerator, the user usually cannot check each reminding message in time, so that the historical reminding messages are accumulated in the notification application and are ignored by the user, and the purpose of reminding the user cannot be achieved. According to the embodiment of generating the reminding message according to the second overdue food material, the problem caused by long-time unread of the history reminding message of the refrigerator end can be solved, and the user is reminded to consume the overdue food material in time while the trouble caused to the user is avoided.

In S502, corresponding reminding messages may be generated according to the target food materials, that is, one target food material corresponds to one single reminding message, and the reminding message corresponding to each target food material at least includes a food material name corresponding to the target food material. And generating only one reminding message according to all the target food materials, wherein the reminding message comprises the food material names of all the target food materials. It should be understood that the reminding message may also include the expiration time, the expiration duration, and/or the food ID of the corresponding target food.

S503, the reminding message is pushed to at least one associated terminal device, so that the reminding message is displayed on the at least one associated terminal device.

The terminal devices associated with the refrigerator include terminal devices in the same local area network or the same group network as the refrigerator, such as a display device, a portable mobile terminal device, a PC device, and the like in a home. The terminal device associated with the refrigerator can also be a terminal device which is associated with the refrigerator based on the service account number.

Illustratively, the account registered by the food management application on the refrigerator is called a primary business account. Then, the terminal device associated with the refrigerator may be a terminal device bound to the main business account, such as a mobile phone, a television, a tablet computer, and the like bound to the main business account. The terminal device may also be a terminal device corresponding to a service account associated with the primary service account, such as a mobile phone, a computer, etc. corresponding to a wechat account associated with the primary service account. The terminal device may also be another terminal device that logs in the primary service account, for example, when the user installs the food management application on the television and logs in the food management application on the television by using the primary service account, the television is called a terminal device associated with a refrigerator.

In some implementations, S503 specifically includes: and the food material management application sends a message pushing request to the server, wherein the message pushing request comprises the main service account and the reminding message generated in the S502. After receiving the message pushing request, the server searches for the terminal equipment associated with the refrigerator according to the main service account, and sends the reminding message to the terminal equipment associated with the refrigerator.

In some implementations, S503 specifically includes: and sending a device discovery message to the terminal device in the local area network, and judging whether active devices exist in the local area network according to whether a response message sent by the terminal device is received.

It should be understood that the active devices at least include terminal devices in a power-on state, and may also include terminal devices in a non-complete standby state, such as terminal devices in a screen-off state, while part of the data processing function and the communication function are in an operating state.

Fig. 6 is an application scenario exemplarily illustrated in the present application. As shown in fig. 6, the scenario includes a local area network I, a refrigerator in the local area network I, and terminal devices a to E, where the terminal device a, the terminal device B, and the terminal device C are active devices in the local area network I. Based on the local area network I, the food management application on the refrigerator may send a device discovery message, such as a UDP (User Datagram Protocol) broadcast message and/or a multicast message, through the communicator. The active devices a-C may receive the device discovery message sent by the refrigerator, and send a response message, such as a UDP unicast message, to the food management application on the refrigerator according to the IP address of the refrigerator in the device discovery message. When the food material management application sequentially receives response messages sent by the active devices A-C within a preset waiting time (5S), the active devices A-C in the local area network can be determined.

In some implementations, the device discovery message includes a UDP broadcast message carrying the device discovery identifier, and the UDP broadcast message includes a home terminal IP address, that is, an IP address of the refrigerator terminal. After receiving the UDP broadcast message sent by the refrigerator, the active equipment in the local area network confirms that the message is an equipment discovery message according to the equipment discovery identification in the UDP broadcast message, resolves the IP address of the refrigerator from the UDP broadcast message in response to confirming that the message is the equipment discovery message, and sends a response message to the UDP broadcast message to the refrigerator according to the resolved IP address, wherein the response message comprises the IP address of the active equipment.

In other implementation manners, the device discovery message includes a multicast message sent to the terminal device in the target networking, and the multicast message carries the device discovery identifier and the home terminal IP address. The target networking refers to networking where the refrigerator terminal is located. After receiving the multicast message sent by the refrigerator, the active device in the target network confirms that the message is a device discovery message according to the device discovery identifier in the multicast message, resolves the IP address of the refrigerator from the multicast message in response to confirming that the message is the device discovery message, and sends a response message to the multicast message to the refrigerator according to the resolved IP address, wherein the response message comprises the IP address of the active device.

In other implementations, the device discovery message includes the UDP broadcast message and the multicast message at the same time, that is, the device discovery message sends the UDP broadcast message to the terminal device in the lan and sends the multicast message to the terminal device in the target network at the same time. And after receiving the UDP broadcast message or the multicast message, the active equipment in the local area network or the active equipment in the target group network sends a response message to the food material management application according to the IP address of the refrigerator in the UDP broadcast message or the multicast message.

In some embodiments, the terminal device in the target group network is all or part of the terminal device in the local area network.

And when the active devices exist in the local area network, pushing the reminding message to at least one active device. And when no active device exists in the local area network, displaying the reminding message on the display through a notification application.

In some embodiments, the IP address of each active device is respectively analyzed from the response message sent by each active device, and then the reminding message generated in S502 is respectively sent to each active device in a UDP unicast manner according to the IP address of each active device, so that each active device displays the reminding message on its screen after receiving the reminding message sent by the refrigerator end.

It can be understood that the terminal device in the local area network includes a display device such as an intelligent television or an intelligent large screen. And after receiving the reminding message sent by the refrigerator end, the terminal equipment displays the received reminding message in the user interface according to preset display logic and a preset display mode. It should be noted that, the logic and the manner of displaying the reminding message by the terminal device are not limited in the present application.

For example, after receiving the reminding message sent by the refrigerator end, the display device may display the reminding message in the current user interface in a modeless dialog box manner, so as to remind the user to consume the expired food material in time, and at the same time, not to influence the user to view or operate the current user interface. Fig. 7 is a user interface of a display device exemplarily shown in the present application, and as shown in fig. 7, the user interface includes a video playing screen 701 and a pop-up window prompt 702 displayed at a position of an upper right corner of an upper layer of the video playing screen 70, where the pop-up window prompt 702 displays text of a reminding message, specifically, "watermelon and yogurt are expired, and please eat in time".

In some embodiments, each terminal device in the local area network or the target group network corresponds to a priority, and different terminal devices correspond to different priorities. In S503, the food material management application determines a preset priority of each active device according to the device information, such as an IP address, of each active device, and determines the active device with the highest priority as the target device. And then, according to the IP address of the target device, sending the reminding message generated in the S502 to the target device so as to display the reminding message in a user interface of the target device, thereby realizing the purpose of reminding the user of consuming the overdue food materials in time.

In conjunction with the application scenario shown in fig. 6, it is assumed that the priorities of the terminal devices a to E in the local area network I are, from high to low, terminal device a, terminal device B, terminal device C, terminal device D, and terminal device E in sequence. And after determining that the active equipment A-C exists in the local area network according to the received response message, the food material management application determines that the active equipment A is the target equipment according to the priority corresponding to the active equipment A-C, and then sends the reminding message to the active equipment A according to the IP address of the active equipment A.

In some embodiments, the notification application is further configured to receive a preset operation, such as a viewing operation, a clearing operation, and the like, on the presented reminder message, which is input by the user. When the notification application receives the preset operation, the reminding message is marked as a read state or a clear state, for example, after the reminding message is viewed, the reminding message operated by the user is marked as a read state, and after the reminding message is cleared, the reminding message operated by the user is deleted. Otherwise (i.e. in case of not receiving the preset operation), the state of the reminding message is kept as an unread state or the reminding message is kept.

It should be noted that the present application does not limit the logic and manner of displaying the reminder message by the notification application. For example, the notification application may display the reminder message on a current user interface of the notification application when the reminder message is received, or may display the received reminder message in the notification bar or the notification message interface when the notification bar or the notification message interface is opened by the user. Fig. 8 is a schematic view of a user interface of a refrigerator display exemplarily shown in the present application, and as shown in fig. 8, a notification message box 802 and a "clear" button are displayed on an upper layer of a food material management interface 801, and text of a reminding message, specifically, "watermelon and yogurt have expired, please eat in time", is displayed in the notification message box 802. The user may click on the "clear" button, dismiss the display of the notification message box, and instruct the notification application to clear the reminder message. The user may also click on the notification message box to view the message details.
