[0072] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0073] In some embodiments, the embodiments of the present disclosure can be applied to the field of intelligent food management, where food management technology includes but is not limited to NFC technology, image recognition, voice recognition technology, smell recognition technology, etc.

[0074] According to some embodiments, for example, a high-resolution camera may be provided in the refrigerator, and the camera may have waterproof and low-temperature resistant functions. The camera may be, for example, a rotating camera, or may be, for example, multiple cameras. The camera may take pictures of the food each time the refrigerator is opened or closed, and an algorithm may be used to identify the date and type of the food. For example, the images captured by multiple cameras may be fused, and the available space may be directly determined based on the fused images. In this process, a relatively complex algorithm needs to be used, and when the camera is unstable, the convenience of food management is poor, and the acquisition time of food identification information is long, resulting in low food management efficiency.

[0075] Figure 1 The structure diagram of a smart refrigerator provided by an embodiment of the present disclosure is shown. The smart refrigerator 10 includes a cabinet 101, a shelf 102 and a controller 103, wherein the shelf 102 is arranged in the cabinet 101, a sensing circuit is arranged in the shelf 102, the controller 103 is arranged on the cabinet 101, and the shelf 102 is electrically connected to the controller 103;

[0076] The shelf 102 is used for collecting a contact signal between the food and the shelf 102 through the sensing circuit when food is placed on the shelf 102 , and transmitting the contact signal to the controller 103 ;

[0077] The controller 103 is used to receive the contact signal and determine the contact area between the food and the shelf 102 according to the contact signal. Therefore, the storage data corresponding to the food can be obtained without setting up a camera, reducing the situation where the camera requirements are too high and the storage data determination is inaccurate due to inaccurate camera recognition, improving the accuracy of storage data determination, and there is no need to use complex algorithms to obtain storage data, which can improve the accuracy of food management while improving the efficiency of food management.

[0078] The cabinet 101 may include, for example, an outer shell, an inner lining, an insulating layer, a table top, etc. The cabinet 101 may function to insulate heat from the outside, so that the temperature inside the cabinet 101 is maintained within a set range.

[0079] The smart refrigerator 10 may also include a shelf without an induction circuit, for example. The shelf without an induction circuit may be a glass shelf 104, or a plastic shelf.

[0080] The smart refrigerator 10 may further include, for example, a blower 105 , a damper 106 , and a fan 107 . The blower 105 , the damper 106 , and the fan 107 may be used to control the temperature in the cabinet 101 .

[0081] According to some embodiments, the shelf 102 can store food, and can also collect data through a sensing circuit to determine the storage information of the food. The sensing circuit can be, for example, a capacitive sensing circuit. An example schematic diagram of a capacitive sensing circuit can be, for example, as shown in FIG. Figure 2 shown.

[0082] The capacitance sensing circuit does not specifically refer to a fixed capacitance sensing circuit. For example, when the number of capacitors included in the capacitance sensing circuit changes, the capacitance sensing circuit may also change accordingly. For example, when the capacitance value corresponding to the capacitor included in the capacitance sensing circuit changes, the capacitance sensing circuit may also change accordingly. The number of capacitors included in the capacitance sensing circuit may be, for example, at least one.

[0083] According to some embodiments, for example, when the capacitive sensing circuit is embedded in the shelf 102, an example schematic diagram of the capacitive sensing circuit may be as follows: Figure 3 shown.

[0084] In some embodiments, the controller 103 may include, for example, a single chip microcomputer and a control board, wherein the control board may be, for example, a PCB board and a plurality of control elements disposed on the PCB board.

[0085] Optionally, the controller 103 may receive a contact signal transmitted by the shelf 102. The controller 103 may determine the contact area and the food storage time point based on the contact signal. The contact area refers to the area corresponding to the contact portion between the food and the shelf. The contact area may be, for example, the area adjacent to the food and the shelf, or may be determined by the shape of the contact. The food storage time point may be, for example, used to indicate the time point when the food is first placed on the shelf. The food storage time point may be, for example, used to indicate the time point each time the food is placed on the shelf.

[0086] According to some embodiments, Figure 4 FIG. 2 shows an example schematic diagram of a food material management system provided by an embodiment of the present disclosure. Figure 4 As shown, the food management system 1 includes: Figure 1 The smart refrigerator 10, server 20 and terminal 30, wherein: the controller 103 is used to transmit the storage data corresponding to the food to the server 20; the server 20 is used to transmit the storage data to the terminal 30.

[0087] The stored data may include, for example, the food storage time point and the contact area. The food storage time point may be, for example, the time point when the food is first placed on the shelf.

[0088] The server 20 may also store the stored data. For example, when the server 20 receives the contact data sent by the controller 103, the stored data may be determined according to the contact data. For example, the server 20 may store data or process data.

[0089] In some embodiments, the controller 103 may transmit the stored data to the server 20 via WIFI, for example.

[0090] The terminal 30 may, for example, receive the stored data transmitted by the server 20. The terminal 30 may store the stored data, and may, for example, display the stored data through a display screen.

[0091] The smart refrigerator 10 may also send the stored data directly to the terminal 30. For example, the smart refrigerator 10 may send the stored data to the terminal 30 via a Bluetooth module.

[0092] The smart refrigerator 10 may also send the stored data to a router, for example. Specifically, the device to which the data is sent may be determined, for example, according to a pre-configuration or according to a sending instruction.

[0093] The food management method disclosed herein is described in detail below in conjunction with specific embodiments.

[0094] In the first embodiment, if Figure 5 As shown, Figure 5 A flow chart of a food material management method provided by an embodiment of the present disclosure is shown, which can be implemented by a computer program and can be run on a device for food material management. The computer program can be integrated into an application or run as an independent tool application.

[0095] Specifically, the food management method includes:

[0096] S101, when food is placed on a shelf of the smart refrigerator, receiving a contact signal transmitted by the shelf;

[0097] In one embodiment of the present disclosure, the execution subject of the present disclosure embodiment may be, for example, a controller in a smart refrigerator. The technical solution of the present disclosure embodiment may be applied to the field of smart refrigerators, and may also be extended to the field of smart food management.

[0098] The contact signal is a signal between the food and the shelf collected by the shelf through the induction circuit set in the shelf. The induction circuit can be, for example, a capacitive induction circuit. The induction circuit does not specifically refer to a fixed circuit. For example, when the induction element corresponding to the induction circuit changes, the induction circuit can also change accordingly. For example, when the number of induction elements corresponding to the induction circuit changes, the induction circuit can also change accordingly.

[0099] According to some embodiments, a smart refrigerator refers to a refrigerator including a shelf, which may include a sensing circuit, for example. The smart refrigerator may also include

[0100] In some embodiments, the shelf is a shelf with an induction circuit embedded therein. The shelf may also be used to place food, for example. The food may be placed directly on the shelf, or may be placed on the shelf by a holding tool.

[0101] According to some embodiments, the contact signal refers to a signal collected by the shelf when the food is in contact with the shelf. For example, when the shelf includes a capacitive sensing circuit, the contact signal may be, for example, a coordinate number. The capacitive sensing circuit may include, for example, at least one capacitor. Each capacitor sequence is marked with a certain coordinate number, for example, each capacitor has a corresponding coordinate number. The capacitor sequence refers to the sequence of all capacitors collected when the food is in contact with the shelf.

[0102] According to some embodiments, when the sensing circuit of the shelf collects the contact signal, the shelf can transmit the contact signal to the controller. Therefore, when there is food placed on the shelf of the smart refrigerator, the controller can receive the contact signal transmitted by the shelf.

[0103] S102, acquiring storage data corresponding to the food according to the contact signal;

[0104] The stored data includes at least one of a storage time point and a first contact area.

[0105] According to some embodiments, the first contact area refers to the contact area between a certain food and the shelf when the food is placed on the shelf. The first in the first contact area is only used to distinguish it from the second contact area. The first contact area does not specifically refer to a fixed area. For example, when the food changes, the first contact area may also change accordingly. For example, when the placement method corresponding to the food changes, the first contact area may also change accordingly. For example, the first contact area corresponding to the same tomato placed directly on the shelf is different from the first contact area corresponding to the tomato placed on a plate and then placed on the shelf.

[0106] The storage time point refers to the time point when the food is stored on the shelf, for example, the time point when the food is first placed on the shelf.

[0107] According to some embodiments, the stored data includes at least one of a storage time point and a first contact area. The stored data may include, for example, a storage time point, the stored data may include, for example, the first contact area, and the stored data may include, for example, the storage time point and the first contact area.

[0108] According to some embodiments, when a contact signal transmitted by a shelf is received, the storage data corresponding to the food may be acquired according to the contact signal.

[0109] According to some embodiments, when the storage data is acquired, the storage data may be transmitted to a data storage device or a data forwarding device, for example.

[0110] According to some embodiments, when the stored data is acquired, the stored data may be transmitted to a server, for example. For example, the stored data may be transmitted to the server via WIFI. When the server receives the stored data, it may store the stored data. For example, when the server receives an access request for the stored data, it may transmit the stored data to a terminal corresponding to the access request.

[0111] For example, when the server receives the stored data, it can directly transmit the stored data to the terminal. The terminal can be, for example, a terminal that has established a connection with the smart refrigerator in advance. The terminal does not specifically refer to a fixed terminal. For example, when the terminal identifier corresponding to the terminal changes, the terminal can also change accordingly.

[0112] Among them, the terminal includes but is not limited to user terminals, smart refrigerators, smart speakers, etc.

[0113] According to some embodiments, when the stored data is acquired, for example, the stored data may also be directly transmitted to the terminal.

[0114] According to some embodiments, when the stored data is acquired, the stored data may be directly transmitted to the router, for example.

[0115] In one or related embodiments, when food is placed on a shelf of a smart refrigerator, a contact signal transmitted by the shelf is received; based on the contact signal, storage data corresponding to the food is obtained; and the storage data is transmitted to a server. Therefore, the storage data corresponding to the food can be obtained without setting up a camera, reducing the situation where the camera requirements are too high and the storage data is inaccurate due to inaccurate camera recognition, improving the accuracy of storage data determination, and there is no need to use complex algorithms to obtain storage data, which can improve the accuracy of food management while improving the efficiency of food management.

[0116] See also Figure 6 , Figure 6 A flow chart of a food material management method provided by an embodiment of the present disclosure is shown. Specifically:

[0117] S201, when food is placed on a shelf of the smart refrigerator, receiving a contact signal transmitted by the shelf;

[0118] The contact signal is a signal between the food and the shelf that is collected by the shelf through a sensing circuit provided in the shelf.

[0119] The specific process is as described above and will not be repeated here.

[0120] According to some embodiments, for example, a compensation algorithm may be used to perform compensation processing on the sensing circuit at preset intervals to obtain a processed sensing circuit. Therefore, the influence of humidity on the sensing circuit can be reduced, the accuracy of the sensing circuit in collecting contact signals can be improved, and the accuracy of food management can be improved.

[0121] The preset duration does not specifically refer to a fixed duration. For example, when a modification instruction for the preset duration is received, the preset duration may also change accordingly.

[0122] According to some embodiments, the preset time length may be, for example, 7 days. A compensation algorithm may be used to perform compensation processing on the sensing circuit every 7 days to obtain a processed sensing circuit. In the case where food is placed on a shelf of the smart refrigerator, a contact signal transmitted by the shelf is received, wherein the contact signal is a signal between the food and the shelf collected by the shelf through the processed sensing circuit provided in the shelf.

[0123] S202, determining a storage time point corresponding to the food according to a receiving time point of the contact signal;

[0124] The specific process is as described above and will not be repeated here.

[0125] When a contact signal is received, the storage time point corresponding to the food can be determined according to the contact signal. For example, the receiving time point corresponding to the contact signal can be obtained, and the receiving time point can be used as the storage time point corresponding to the food. For example, the receiving time point corresponding to the contact signal can also be obtained, the receiving time point can be corrected to obtain the corrected receiving time point, and the corrected receiving time point can be used as the storage time point corresponding to the food.

[0126] For example, the contact signal may include a signal collection time point, and the signal collection time point may be directly used as the storage time point corresponding to the food.

[0127] S203, determining a first contact area corresponding to the food according to the coordinate information set;

[0128] The coordinate information set may include, for example, at least one coordinate. The coordinate information set does not specifically refer to a fixed set. For example, when any coordinate information included in the coordinate information set changes, the coordinate information set may also change accordingly. For example, when the number of coordinates included in the coordinate information set changes, the coordinate information set may also change accordingly.

[0129] According to some embodiments, the first contact area corresponding to the food material may be determined according to the coordinate information set. For example, the contact shape corresponding to the food material may be determined according to the coordinate information set, and the area corresponding to the contact shape may be used as the first contact area. For example, the first contact area may also be directly calculated according to the coordinate information set. The controller may include, for example, a single-chip microcomputer and a control board. The single-chip microcomputer may, for example, calculate the first contact area according to the coordinate information set.

[0130] According to some embodiments, for example, it may also include: according to the contact signal, obtaining the food category corresponding to the food, and obtaining the day threshold corresponding to the food category; obtaining the storage days of the food according to the storage time point; when the storage days are greater than the day threshold, sending a first reminder message to the server, wherein the first reminder message is used to instruct the server to send a reminder message to the terminal, and the first reminder message is used to prompt the expiration risk information corresponding to the food. Therefore, it is determined whether the food is good according to the day threshold. In the case of expiration risk, the time it takes for the user to obtain the expiration risk information of the food can be reduced, and the efficiency of information transmission can be improved so that the food can be processed in time. Among them, the expiration risk information can remind the user to eat it as soon as possible or take it off the shelf as soon as possible.

[0131] According to some embodiments, when obtaining the food category corresponding to the food, for example, the capacitance value corresponding to the contact signal is obtained, and the food category corresponding to the capacitance value is obtained according to the correspondence table between the capacitance value and the food category. The correspondence table can be, for example, a pre-stored correspondence table between the capacitance value and the food category. When determining the capacitance value according to the contact signal, the food category corresponding to the capacitance value can be directly queried from the correspondence table, without using a complex algorithm to obtain the food category, which can improve the efficiency of determining the food category.

[0132] According to some embodiments, when obtaining the food category corresponding to the food, for example, the capacitance value corresponding to the contact signal can be obtained, and when the capacitance value meets the capacitance value reminder condition, a first reminder message is issued, and the food category input for the first reminder message is received. Therefore, the situation where non-food materials directly contact the shelf, resulting in inaccurate food determination, can be reduced, the accuracy of food category determination can be improved, and the convenience of food management can be improved.

[0133] For example, when a tomato is placed in a plate and the plate is placed on a shelf, the acquired capacitance value may indicate that the object is a plate, and a first reminder message may be issued.

[0134] The capacitance value reminder condition may be, for example, that a reminder is issued when the determined capacitance value is a preset capacitance value.

[0135] In some embodiments, the first reminder information may be, for example, a reminder information for obtaining a food category. The first reminder information is only used to distinguish from other reminder information. It does not specifically refer to a fixed reminder information. For example, when the reminder time point corresponding to the first reminder information changes, the first reminder information may also change accordingly.

[0136] According to some embodiments, when obtaining the food category corresponding to the food, for example, the capacitance value corresponding to the contact signal is obtained, and the food category corresponding to the capacitance value is obtained according to the correspondence table between the capacitance value and the food category. In the case where the food category corresponding to the capacitance value is determined from the correspondence table, for example, prompt information for the food category can also be issued. When a confirmation instruction for the prompt information is received, the food category corresponding to the capacitance value is determined to be the food category determined from the correspondence table. When a modification instruction for the prompt information is received, the food category corresponding to the capacitance value is determined to be the food category corresponding to the modification instruction.

[0137] According to some embodiments, the method further includes: obtaining a second contact area corresponding to at least one food material placed on the shelf according to the first contact area, wherein the second contact area is the total contact area corresponding to the at least one food material; sending a second reminder message to the server when the second contact area is less than the first contact area threshold, wherein the second reminder message is used to instruct the server to send a reminder message to the terminal, and the second reminder message is used to prompt the replenishment of at least one food material; sending a third reminder message to the server when the second contact area is greater than or equal to the second contact area threshold, wherein the third reminder message is used to instruct the server to send a reminder message to the terminal, and the third reminder message is used to prompt the consumption of at least one food material, wherein the second contact area threshold is greater than the first contact area threshold. Therefore, reminder messages can be sent according to the contact area threshold, which can improve the convenience of food material management.

[0138] According to some embodiments, the second contact area may be, for example, the total contact area corresponding to at least one food material, and the second contact area may be, for example, determined based on the first contact area corresponding to a certain food material. The second contact area does not specifically refer to a certain fixed area. For example, when at least one food material changes, the second contact area may also change accordingly. For example, when any first contact area changes, the second contact area may also change accordingly.

[0139] The second reminder information may be, for example, information for reminding that the food is too little. The third reminder information may be, for example, information for reminding that the food is too much.

[0140] When the server receives any reminder information, the server may send the reminder information to the terminal. The terminal may display the reminder information. The terminal may display the box pick-up information on a display screen, for example. The terminal may play the box pick-up information in voice, for example.

[0141] Among them, step S202 and step S203 can be performed one by one or simultaneously. For example, step S202 and step S203 can be performed simultaneously, for example, only step S202 can be performed, and for example, only step S203 can be performed.

[0142] According to some embodiments, Figure 7 FIG. 1 is a flow chart showing a method for managing food materials provided by an embodiment of the present disclosure. Figure 7 As shown, for example, food can be placed on the shelf of the smart refrigerator. The shelf can collect contact signals through a capacitive sensing circuit and transmit the contact signals to the controller. The MUC of the controller can process the contact signals and exchange information with the server through the WIFI module. For example, the MUC determines the capacitance change value according to the contact signal, determines the first contact area of ​​the food according to the capacitance change value, and transmits the first contact area to the server through the WIFI module. For example, when the second contact area of ​​the food storage video area is too large or too small, the controller can send a second reminder message or a third box pick-up message to the server. The server can send the second reminder message or the third box pick-up message to the terminal. For example, when the storage days of the food are greater than the preset number of days, the controller can send a first reminder message to the server. The server can send the first reminder message to the terminal. Among them, the terminal includes but is not limited to a user terminal, a smart refrigerator, a smart speaker, etc. For example, the terminal can display the reminder message through a display. For example, the smart refrigerator can display the reminder message through the display screen of the smart refrigerator. For example, the smart speaker can play the reminder message by voice.
