DETAILED DESCRIPTION
As shown in FIG. 1 , an embodiment of the present invention discloses an ingredient updating method, including the following steps.
S101 : Obtain tag information, tags being removably attached on an ingredient. Specifically, each obtained tag has a unique ID and tag information can be read through a tag reader. The tags are used to mark different types of ingredients, such as meat and fishes, and can be separated from marked ingredients and used repeatedly.
S102: Determine whether the tag information has a newly added tag; if the tag information has a newly added tag, determine whether an ingredient corresponding to the newly added tag is a newly added ingredient, and update an ingredient list if the ingredient is a newly added ingredient.
Specifically, whether there is a newly added tag is determined according to the ingredient list of a system before obtaining the current tag information. If the tag information has no newly added tag, and ingredient entries in the ingredient list are more than tag entries obtained currently, the redundant entries are deleted from the ingredient list.
If there is a newly added tag, whether a time interval from last update of tag information is not greater than a preset time interval, that is, 24 hours, is determined. If the time interval is not greater than the preset time interval, the ingredient corresponding to the tag is determined not to be a newly added ingredient. Optionally, a user is reminded to determine whether the ingredient is a newly added ingredient. The time interval from last update of tag information includes a time interval from latest deletion of the tag information.
Furthermore, when the user is reminded to determine whether the ingredient is a newly added ingredient and a feedback signal determining that the ingredient is a newly added ingredient is received, the tag, the ingredient information corresponding to the tag, and current storage time are matched, and the ingredient is added to the ingredient list, or when a feedback signal denying that the ingredient is a newly added ingredient is received, the tag, the ingredient information corresponding to the tag, and placement time recorded last time are matched and the ingredient is added to the ingredient list.
The foregoing method can manage ingredient update efficiently, so that ingredients are not input repeatedly, entries of ingredients that have been taken out can be deleted in time, and same ingredients that are put in again can be recognized precisely. There are two types of tags, that is, predefined tags and user-defined tags. The predefined tags mean that parameters of each tag are preset in a database when a product leaves factory, for example, types or names of ingredients characterized by each tag. On the contrary, the user-defined tags do not have parameters defined in the database when being used for the first time, that is, corresponding values are blank, and the values can be defined by a user during use according to demand. Furthermore, the predefined tags and the user-defined tags both have images, text or colors for distinguishing. The tag may be an RFID tag. A user can use the user-defined tag to mark a special ingredient conveniently, especially an ingredient not input in a preset ingredient content database.

The physical tags are used to mark ingredients put in the refrigerator and can be attached on ingredients when the ingredients are put in the refrigerator, and the tags can be removed and used repeatedly.
Referring to FIGs. 4-6, the system realizes ingredient updating in following specific procedures.
After an ingredients with a tag is put in a storage chamber of the refrigerator, the tag reader of the refrigerator reads tag information, for example, after a door of the refrigerator is closed, the reader is started to read information, and generate a temporary list storing the read information. Some tags are predefined and some are user-defined. Furthermore, the tags are removably attached on surfaces or packages of ingredients, and can be used repeatedly.
A predefined tag means that the system defines a corresponding parameter for each tag in the database, for example, a type of an ingredient corresponding to the tag and a name of the ingredient. In a specific application, optionally, tag types of five common ingredients are predefined in the system, including fishes, pork, chicken, dumplings, and sausage. Correspondingly, a tag has text or an image on an outer surface thereof to characterize a type or a name of an ingredient marked by the tag, and can be used repeatedly by a user.
As shown in FIG. 4, when the reader detects tag information carried by the ingredient, a menu list needs to be updated. Specifically, referring to FIG. 6, the system reads a record from a temporary list formed by current reading and determines whether the record is a new record, that is, determines whether there is a new record by comparing the current temporary list and the current menu list, that is, whether a new tag is detected. One record at least includes at least one of following fields: ingredient type, ingredient name, and tag ID.
If there is a new record, whether an ingredient corresponding to the new record is an ingredient that has been partially used before and then put in the refrigerator again is further determined, that is, whether the tag marking the ingredient is detected again by the system in a certain period of time is determined. If yes, data of a previous record corresponding to the ingredient is associated with the current record, specifically, at least information such as previous storage start time and shelf life of the ingredient is added to the current record and the associated current record is added to the ingredient list. Alternatively, to determine an ingredient more accurately, a user can be reminded to determine whether the ingredient is an original ingredient or a newly added ingredient through a touch screen or a mobile terminal interface. The user feeds back information through the interface, and after receiving the feedback of the user, the system updates the ingredient list according to different determining results.
If the tag is detected again after a certain period of time, the ingredient marked by the tag is considered as a new ingredient by default. Then, the current record is information in the ingredient content database, and the associated record is added to the ingredient list. Content that needs to be associated at least includes a type, a name, a recommended shelf life, a recommended menu, and the like of an ingredient. Preferably, the foregoing certain period of time can be 24 hours after latest deletion of the same tag information or other time. The ingredient content database stores information of most common ingredients preset in the server of the system, including names and shelf lives of ingredients. When an ingredient is put in the refrigerator, the system matches corresponding information in the ingredient content database according to tag information, to realize inputting and deletion of an ingredient list.
For example, the user puts a piece of fish with a tag a in the refrigerator. The refrigerator detects the tag a. If the fish is a new ingredient, the system will input the fish and the information of the tag a in the ingredient list and present on the terminal. If the fish is put in the refrigerator again after a part thereof has been used by the user, the system first determines that a time interval from taking out the fish to putting in the fish again is less than a preset time interval, and then obtains and associates previous information of the ingredient such as storage start time and shelf life and inputs it in the ingredient list.
If the current record is determined not to be a new record, a next record in the temporary list is read. Alternatively, when an ingredient is taken out from the refrigerator, the temporary list is compared with the ingredient list. If the temporary list does not record the entry or records in the temporary list are less than those in the ingredient list, the redundant entries are deleted from the ingredient list.
A user-defined tag means that a tag has no specific ingredient information defined in the database, and the parameter needs to be maintained or defined by the user. An appearance of the tag may be distinguished by a different color or number. When the system detects this type of tag, information such as a type or name of an ingredient corresponding to the tag can be input or selected through a touch screen or a mobile terminal interface, to maintain the information of the tag in the system. Procedures of inputting, deleting, and updating the ingredient information marked by the tag are the same as processing procedures of a predefined tag. The updated ingredient list is presented by the touch screen or mobile terminal of the refrigerator. As shown in FIG. 5, a user can click related entries to view attributes of a corresponding ingredient, such as a storage date, a shelf life, and a storage position. Information of various ingredients, such as storage dates, shelf lives, recommended menus, and recommended storage conditions, are preset in the ingredient content database. The system calculates remaining storage time of an ingredient according to a storage data and a shelf life of the ingredient, and reminds a user to deal with the ingredient in time when the ingredient approaches the expiry date.
A person skilled in the art can understand all or partial steps of various methods in the foregoing embodiment can be implemented by instructing related hardware through a program. The program can be stored in a computer readable storage medium, and the storage medium includes ROM, RAM, a magnetic disk, or an optical disk.
Although the present invention is disclosed as above, the present invention is not limited thereto. A person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and the protection scope of the present invention should depend on the scope defined by the claims.
