[0050] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.
[0051] Since in some technologies, refrigerators with NFC functions require mobile phones to support NFC functions, which limits the scope of use of refrigerators. In order to solve this technical problem, this application provides a refrigerator NFC tag management device. The following describes the structures of various parts of the refrigerator NFC tag management device:
[0052] Depend on Figure 1It can be seen that the present application provides a refrigerator NFC tag management device, including: an NFC tag reading and writing module 1 and a display interaction module 2 arranged in the box body, the NFC tag reading and writing module 1 is communicatively connected with the display interaction module 2; the NFC tag reading and writing module 1 has the function of reading NFC tag information, and has the function of writing relevant information into the NFC tag; the display interaction module 2 can display the current food information, including the storage date of each food, and prompt the expiring or expired food; the display interaction module 2 also has a key interaction function, and the food entry function or food deletion function of the device can be turned on by pressing a button, so as to realize the food entry and deletion operations.
[0053] The NFC tag reading and writing module 1 is configured to: read the food information of the NFC tag 3 and send it to the display interaction module 2; the NFC tag 3 is used to store food information. The user can enter the food information through the NFC tag reading and writing module 1, and then stick the corresponding NFC tag 3 on the corresponding food. If the user wants to view the storage information of the food, the NFC tag 3 attached to the food can be removed, and the tag information of the NFC tag 3 can be read by the NFC tag reading and writing module 1 to obtain the storage time and other information of the food, so as to obtain the freshness of the food and then eat the food; the display interaction module 2 is configured to: obtain whether the database includes the tag information corresponding to the food information, and if so, display the tag information; the tag information includes: food information and food storage time; if not, the tag information of the NFC tag 3 is stored in the database and displayed. It can be understood that the NFC tag 3 itself stores food information, such as beef, mutton, etc. Figure 2 As shown, if the food storage time is not stored in the NFC tag 3, when the NFC tag reading and writing module 1 reads it, the time of reading the NFC tag 3 is automatically stored in the database as the food storage time and the food information. When the user reads the NFC tag 3 again, the tag information of the food can be obtained, thereby realizing the management of the food.
[0054] For example, Figure 6 As shown, in addition to synchronizing food information, the device can also synchronize other status data of the refrigerator, such as refrigerator failure status, door opening status, etc., and can better interact with the user based on these data. For example, when the refrigerator door is detected to be closed, it automatically enters the sleep mode; when a sensor failure is detected in a compartment, it prompts the food stored in the corresponding compartment, etc.
[0055] Depend on Figure 1It can be seen that the device also includes: a terminal device 4, which is connected to the display interaction module 2 through the Internet of Things module 5; the terminal device 4 has an NFC function; the terminal device 4 is configured to: read the food information of the NFC tag 3, and if the database includes the tag information corresponding to the food information, then display the tag information; if the database does not include the tag information corresponding to the food information, then store the tag information of the NFC tag 3 in the database and display it. Figure 2 As shown, if the food storage time is not stored in the NFC tag 3, when the terminal device 4 reads it, the time of reading the NFC tag 3 is automatically stored in the database as the food storage time and the food information. When the user reads the NFC tag 3 again, the label information of the food can be obtained, thereby realizing the management of the food. The label information can be displayed through the terminal device 4.
[0056] In this embodiment, the display interaction module 2 is further configured to: obtain the food freshness time based on the food information; the database stores the freshness time of various types of food, such as the food freshness time of bananas is 5 days; calculate the difference between the food storage time and the food freshness time; obtain food freshness information based on the difference; the food freshness information includes: fresh state, near-expiry state, and expired state; the food freshness information is displayed through the display interaction module 2 or the terminal device 4. The food freshness information of the food can be obtained by calculating the difference between the food storage time and the food freshness time, so that the user can eat and manage the food more intuitively.
[0057] In this embodiment, the display interaction module 2 is further configured as follows: if the difference is not less than the first preset value, the food is in a fresh state; if the difference is less than the first preset value and greater than the second preset value, the food is in a near-expiry state; if the difference is not greater than the second preset value, the food is in an expired state and the food information corresponding to the expired state is displayed. For example, if the shelf life of banana food is 5 days, if the first preset value is 2, then the food freshness information is in a fresh state if the first three days are stored; if the first preset value is 0, then the food freshness information is in a near-expiry state if the fourth day is stored, and the food freshness information is in an expired state if the storage time exceeds four days.
[0058] In this embodiment, the NFC tag 3 includes a first NFC tag and a second NFC tag; the first NFC tag is set with food information, and the second NFC tag is not set with food information. The NFC tag 3 includes a tag with a preset name (such as beef, mutton, etc.), namely the first NFC tag, and also includes a blank tag with editable information, namely the second NFC tag; the user can write food information into the NFC tag 3 through the terminal device 4 or the NFC tag reading and writing module 1, thereby increasing the comprehensiveness of the food information covered by the NFC tag 3.
[0059] Depend on Figure 5 It can be seen that the terminal device 4 is also configured to write the food information to be edited into the second NFC tag. If the terminal device 4 has an NFC function, the second NFC tag can be directly placed close to the NFC detection end of the terminal device 4, and the food information, such as the food name, can be edited using the APP of the terminal device 4. After the editing is completed, the NFC tag 3 can be written through the terminal device 4.
[0060] Depend on Figure 5 It can be seen that the display interaction module 2 is also configured to: receive the food information to be edited sent by the terminal device 4 and send it to the NFC tag reading and writing module 1; the NFC tag reading and writing module 1 is also configured to: write the food information to be edited into the second NFC tag. If the terminal device 4 does not have the NFC function, the food information, i.e., the food name, etc., can be edited in the APP of the terminal device 4 first, and then the food information is sent to the display interaction module 2, and then the food information is sent to the NFC tag reading and writing module 1 through the display interaction module 2, and the food information is written into the second NFC tag through the reading function of the NFC tag reading and writing module 1.
[0061] Depend on Figure 3 It can be seen that the terminal device 4 is also configured to delete the tag information in the database. If the terminal device 4 has an NFC function, the tag information in the database can be directly deleted through the APP of the terminal device 4. After the user has viewed the tag information of the NFC tag 3 and eaten the corresponding food, if the terminal device 4 has an NFC function, the tag information in the database can be deleted through the APP of the terminal device 4, and then the NFC tag 3 can be stored for subsequent use.
[0062] Depend on Figure 4It can be seen that the device is provided with an NFC tag recycling end, and the NFC tag recycling end is used to store the NFC tag 3; the NFC tag reading and writing module 1 is also configured to: obtain whether the NFC tag recycling end stores the NFC tag 3, and if so, read the tag information of the NFC tag 3 stored in the NFC tag recycling end; if the tag information is stored in the database, delete the tag information. The refrigerator NFC tag management device provided in the present application is provided with an NFC tag recycling end, which is used to store the NFC tag 3. After the user has checked the tag information of the NFC tag 3 and eaten the corresponding food, the NFC tag 3 with the tag information to be deleted can be placed in the NFC tag recycling end provided by the refrigerator NFC tag management device. The NFC tag recycling end can interact with the NFC tag reading and writing module 1, read the NFC tag 3 stored in the NFC tag recycling end, and after reading the tag information of the NFC tag 3, match it with the tag information stored in the database, and if the same tag information exists, delete the corresponding tag information, thereby completing the deletion of the tag information.
[0063] Depend on Figure 1 It can be seen that the device further includes: a power supply module 6, the power supply module 6 is electrically connected to the NFC tag reading and writing module 1, the display interaction module 2, and the Internet of Things module 5; the power supply module 6 is configured to: supply power to the NFC tag reading and writing module, the display interaction module 2, and the Internet of Things module 5; wherein, the NFC tag reading and writing module 1 and the display interaction module 2 are arranged outside the box through the power supply module 6.
