DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
In order to make the technical solution of the present invention better understood by those skilled in the art, the technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
The refrigerator food material management method provided by the embodiment of the invention can record the use data of the user and automatically set the preservation priority weight of each article according to the characteristics of the use data of the user, the price of the article and the like.
First embodiment
Referring to fig. 1, the method for managing food materials in a refrigerator according to an embodiment of the present invention includes the following specific steps:
identifying the type of the article in the refrigerator;
acquiring the storage times of the articles in a preset time period;
and matching the storage priority weight of the article according to the storage times.
The preset time period may be in the period of about several months, or may be a certain time period of history, for example, a certain month of the last year, from the time when the user uses the refrigerator to the time when the storage times of the articles are obtained. The preservation priority weight indicates the priority level of the articles in preservation, and the refrigerator can adjust the storage parameters such as temperature, humidity and the like in the compartment according to the preservation priority weight of the articles. The higher the priority of preservation of an item, the higher the importance of that item, the closer the final storage parameter within the refrigerator is to the optimal storage parameter for that item. Specifically, the save priority weight is in the range of 1-10. Food material information libraries are preset in the refrigerator or the cloud end, and the preset food material information libraries are queried according to the storage times to obtain the storage priority weight. Therefore, the storage habit of the user in the preset time period is judged according to the storage times of the articles, and the storage priority weight of the articles is matched conveniently and rapidly.
Further, the step of "identifying the kind of the article in the refrigerator" includes:
receiving an opening signal of a refrigerator door body;
acquiring the types of the articles stored in the refrigerator before the door body is opened;
identifying the type of the stored article and the type of the taken article;
receiving a closing signal of the door body;
and identifying the type of the articles in the refrigerator after the door body is closed.
The method for identifying the types of the articles can be implemented in various ways, and the types of the articles can be identified by inputting the user through an input device arranged on the refrigerator or the mobile terminal, wherein the input device can be a physical key or a touch screen or a voice input module; in some alternative embodiments, the automatic identification device can be used for identifying the type of the article, specifically, an image identification device can be arranged in the refrigerator, when a user stores the article, the user takes a picture of the article through a camera and uploads the picture to a cloud database, the article information is obtained through image comparison, or an RF I D identification device is arranged on the refrigerator, an identification code is arranged on the article, and the information of the article is obtained through the identification code of the identification device.
The types of the articles in the refrigerator after the door body is closed are the types of the articles in the refrigerator before the door body is opened, the types of the articles to be taken out are deleted, and meanwhile, the types of the articles to be put in are increased.
Of course, it is possible to identify the type of the article in the refrigerator after the door body of the refrigerator is closed, and then compare the type of the article in the refrigerator after the door body is closed with the type of the article in the refrigerator before the door body is opened, so as to obtain the type of the stored article and the type of the taken out article. Specifically, for example, a camera in the refrigerator is used for shooting a picture uploading cloud comparison in the refrigerator before and after a user accesses the article, and the type of the article stored in the refrigerator, the type of the article stored in the refrigerator and the type of the article taken out are obtained.
Further, after identifying the type of the stored article, the food material management method further includes:
judging whether the type of the stored article is the same as the type of the article taken out in the preset period;
if yes, prompting a user to confirm whether the stored article is the taken article in the preset period;
if the user selects no, the type of the stored article and the stored data are recorded.
The predetermined period is a period of time before the user stores the article, and specifically, the predetermined period may be four to eight hours before the user stores the article. By judging whether the article is the article taken out in the preset period, the phenomenon that the user only uses part of the article to put the article into the refrigerator after taking out the article and repeatedly records and stores data for the same article is avoided.
Further, in an embodiment, after identifying the type of the stored article, the method further includes:
recording the time of storing the stored article;
the method for obtaining the storage times of the articles in the preset time period comprises the following steps:
acquiring the storage time of the article in a preset time period;
and calculating the storage times of the objects in a preset time period, wherein the storage times in the preset time period are equal to the number of the storage times in the preset time period. In a specific example, when a user puts bananas in the refrigerator, the storage time of the bananas is recorded, and when the storage times in one month need to be acquired, the storage time of the bananas recorded in one month is called, wherein the number of the storage times is the storage times of the bananas in one month.
In another embodiment, after identifying the type of item being deposited, further comprising:
acquiring the historical storage times of the stored articles;
and calculating and updating the storage times of the stored articles, wherein the storage times are equal to the historical storage times plus one.
The historical storage times are the storage times of the articles stored in the refrigerator when the articles are put in by a user. If a user puts an article for the first time, the historical storage times of the article are 0, and the storage times after the article is put are updated to be 1. Therefore, the article storage times are directly recorded when the articles are stored, and the article storage times can be directly called after the types of the articles in the refrigerator are identified.
Further, in one embodiment, matching the storage priority weight of the item according to the storage times includes:
sorting the articles in the refrigerator according to the storage times, and obtaining the frequency ranking corresponding to the articles;
inquiring a preset food material information base according to the frequency ranking, and matching the storage priority weight of the article, wherein the storage priority weight corresponding to each frequency ranking is stored in the food material information base.
The plurality of storage times of the articles indicates that the articles are articles stored frequently in the refrigerator, and the user can judge that the favorability or importance of the articles is higher, so that the articles with the plurality of storage times, namely the articles with the top ranking times, can be matched with higher storage priority. Of course, because the storage times are more representative of the high storage frequency, the user storage time is shorter, the consumption rate of the articles is fast, and the fresh-keeping requirement of the user is lower, therefore, the method can be implemented, and the articles with more storage times are matched with low storage priority weights.
Further, in one embodiment, after matching the storage priority weight of the item according to the storage times, the method further includes:
obtaining optimal storage parameters of articles in the refrigerator;
Calculating optimal compartment parameters based on the optimal storage parameters and the preservation priority weights for each item.
Wherein the optimal storage parameter is one or more of optimal storage temperature, optimal storage humidity and optimal storage gas concentration, and when the relevant parameter of the storage environment of the article is set as the optimal storage parameter, the storage time of the article is longest. The refrigerator food material information base is preset in a database or a cloud database of the refrigerator, and optimal storage parameters corresponding to each article are stored in the food material information base.
The optimal compartment parameter is the parameter which can achieve the optimal fresh-keeping effect according to the requirement of the user when the parameter in the refrigerator compartment is adjusted to the parameter.
In one embodiment, the best storage parameter for holding the highest priority item may be set to the best compartment parameter, thereby prioritizing the holding of the most important items. In another embodiment, the optimal compartment parameter may be calculated according to a preservation priority weight, and specifically, the optimal compartment parameter is f= (a1f1+a2f2+ … +anfn)/(a1+a2+ … +an), where F is the optimal compartment parameter, an is the preservation priority weight of each item, and Fn is the optimal storage parameter of each item. By combining the storage priority weight and the optimal storage parameter of each article, the optimal compartment parameter is calculated, so that the optimal fresh-keeping effect can be realized according to the user requirement.
Second embodiment
The difference between the refrigerator food material management method according to the second embodiment of the present invention and the first embodiment is that in this embodiment, the refrigerator food material management method matches the storage priority weight of the article according to the price of the article and the storage times in the preset time period. Referring to fig. 2, the refrigerator food material management method specifically includes the steps of:
identifying the type of the article in the refrigerator;
acquiring the price of the article and the storage times in a preset time period;
matching a first storage priority weight of the article according to the storage times;
matching a second holding priority weight of the item according to the price;
and matching the storage priority weight of the article according to the first storage priority weight and the second storage priority weight.
The price of the article can be the unit price of the article or the total price of the article. A specific method for identifying the kind of the article and obtaining the number of times the article is stored in a preset time period is referred to the first embodiment.
The storage priority weights of the articles are as follows: a=n1a1+n2a2. Wherein A is the storage priority weight, A1 is the first storage priority weight, A2 is the second storage priority weight, and n1 and n2 are preset coefficients. The n1 and n2 may be adjusted according to the user requirement, for example, if the price storage frequency is considered to be equally important, n1=n2 may be taken, if the price factor is considered to be more important than the storage frequency, n1> n2 may be taken, and of course, n1 and n2 may be calculated by comprehensively considering other factors such as storage time. Food material information bases are preset in the refrigerator or the cloud end, and the preset food material information bases are queried according to the storage times and the prices to obtain a first storage priority weight and a second storage priority weight. Therefore, the price and the preservation times of the articles are comprehensively considered to calculate the preservation priority weight of the articles, the accuracy of the preservation priority weight is improved, and the situation that the preservation priority weight is low and the preservation is not in place due to the fact that the number of times of preservation of the valuables is small is prevented.
Further, obtaining the price of the item includes:
detecting the storage amount of the article;
inquiring a preset food material information base according to the types of the articles to obtain the unit price of the articles, wherein the food material information base is preset in a refrigerator database or a cloud database, and the unit price corresponding to each article is stored in the food material information base;
and calculating the price of the article according to the storage quantity and the unit price.
The storage amount can be storage weight or storage quantity, and when the storage amount of the article is detected, the storage weight or the storage quantity of the article is selectively detected according to the type of the article. Specifically, after the type of the article is identified, whether the price of the article is calculated according to the weight or the piece is judged according to the type of the article. For heavily rated items, the storage weight of the item may be obtained by a weight sensor or direct user input, or the like. For the articles which are counted according to the articles, the storage quantity of the articles, namely the number of the articles, can be identified specifically through images, or identification codes are arranged on each article, and the storage quantity of the articles is judged through the number of the identification codes. In a specific example, if the stored item is identified as a watermelon, the stored weight of the watermelon is detected, and if the stored item is identified as a kiwi fruit, the stored number of kiwi fruits is detected.
The price of the item is equal to the product of the unit price of the item and the deposited amount. Therefore, the price calculating mode is selected according to the type of the article, and the accuracy is high.
Further, matching the first storage priority of the article according to the storage times includes:
sorting the articles in the refrigerator according to the storage times, and obtaining the frequency ranking corresponding to the articles;
inquiring a preset food material information base according to the frequency ranking, and matching the first storage priority weight of the article, wherein the first storage priority weight corresponding to each frequency ranking is stored in the food material information base.
The article with the larger number of times of storage indicates that the article is often stored in the refrigerator, and it can be determined that the user has a higher preference for the article, so that the article with the larger number of times of storage, that is, the article with the higher number of times of storage is matched with a higher priority of storage. Of course, because the storage times are more representative of the high storage frequency, the consumption rate of the user is high, the storage time of the articles is short, and the fresh-keeping requirement of the user is low, the method can be implemented, and the articles with more storage times are matched with low storage priority weights.
Further, matching a second preservation priority weight of the item according to the price, comprising:
And inquiring a preset food material information base according to the prices, and matching second preservation priority weights of the articles, wherein the second preservation priority weights corresponding to each price are stored in the food material information base.
Specifically, the higher second storage priority weight is matched with the high-priced article, so that the storage priority weight of the valuable article can be improved.
Third embodiment
The difference between the refrigerator food material management method provided by the third embodiment of the present invention and the first embodiment is that in this embodiment, the refrigerator food material management method matches the storage priority weight of the article according to the accumulated storage duration of the article in the preset time period, referring to fig. 3, the refrigerator food material management method specifically includes the steps of:
identifying the type of the article in the refrigerator;
acquiring a single storage time length of the article in a preset time period;
screening the data with the single storage time length smaller than a storage time length threshold value;
calculating the accumulated storage time length of the articles, wherein the accumulated storage time length is equal to the sum of the data of which the single storage time length is smaller than the storage time length threshold value;
and matching the storage priority weight of the article according to the accumulated storage duration.
The method comprises the steps of storing a single storage time length in a refrigerator, wherein the single storage time length is the time length from the time of putting in to the time of taking out an article after a user stores the article in the refrigerator, the accumulated storage time length is the sum of the single storage time lengths of the article when the article of the same type is put in for a plurality of times, and in order to improve the accuracy of data, the data with the single storage time length larger than a storage time length threshold value is deleted when the accumulated storage time length is calculated. The storage duration threshold is stored in the database in advance, can be a fixed value or can be a variable, when the single storage duration of the article is longer than the storage duration threshold, the storage duration of the article in the refrigerator is overlong, the article can be judged to be the article forgotten to be taken out by the user, and the single storage duration is abnormal data. Food material information libraries are preset in the refrigerator or the cloud end, and the preset food material information libraries are queried according to the accumulated storage time to obtain the storage priority weight.
The accumulated storage time of the articles in the preset time period can be used for judging whether the articles are stored in the refrigerator frequently or not, and the articles stored frequently can be kept fresh in a biased manner. Meanwhile, by deleting the data with longer single storage time, the influence on the storage priority weight caused by the fact that the user forgets to take out the stored articles is prevented.
Further, in an embodiment, the refrigerator food material management method further includes:
after the type of the stored article is identified, starting a timer corresponding to the stored article;
and stopping the timer corresponding to the removed object after the type of the removed object is identified, and recording the single storage time length of the removed object, wherein the single storage time length of the object is the time length recorded by the corresponding timer when the object is removed.
The timer can be a timer which is independently arranged on the refrigerator and is controlled to be opened or closed by a user, and can also be a timing module which is arranged in the refrigerator and is automatically triggered after the type of the article is identified.
In another embodiment, after identifying the type of the item to be deposited, the deposit time of the item to be deposited is recorded;
recording the taking-out time of the taken-out article after identifying the type of the taken-out article;
the method for obtaining the single storage time of the article in the preset time period comprises the following steps:
obtaining the storage time of the article and the corresponding taking-out time of each storage time in a preset time period, and calculating the single storage time length, wherein the single storage time length is equal to the difference value between the taking-out time and the corresponding storage time.
Further, in an embodiment, before screening the data with the single storage duration less than the single storage duration threshold, the method further includes:
obtaining the optimal storage time of the article;
and calculating a storage time threshold according to the optimal storage time.
The optimal storage time length is the time length required by the objects to reach the deterioration critical point under the preset condition, the optimal storage time lengths of different objects are different, and the optimal storage time lengths are also different when the same object is stored under different storage conditions.
The storage duration threshold is determined based on the optimal storage duration for each item. Specifically, the storage time threshold is N times of the optimal storage time, that is, the corresponding storage time threshold is adjusted according to the type of the article, and generally, N is between 1 and 1.5. If the optimal storage time length of tomatoes is 5 days, N is preset to be 1.2, the storage time length threshold is 6, and when the accumulated storage time length is calculated, the range of the accumulated storage time length is not counted for data with the single storage time length longer than 6 days, so that the situation that a certain article user forgets to take out the article after storing the article is avoided, and the accuracy of storing the priority weight is influenced.
Further, obtaining the optimal storage time of the article includes:
Inquiring a preset food material information base according to the types of the articles to obtain the optimal storage time of the articles, wherein the optimal storage time corresponding to each article is stored in the food material information base.
Further, in one embodiment, matching the storage priority weight of the item according to the accumulated storage duration includes:
sorting the articles in the refrigerator according to the accumulated storage duration, and acquiring accumulated duration ranking corresponding to the articles;
inquiring a preset food material information base according to the accumulated time ranking, and matching the storage priority weights of the articles, wherein the storage priority weights corresponding to each accumulated time ranking are stored in the food material information base.
The articles with longer accumulated storage time length, namely the articles with the upper accumulated time length, represent the articles stored in the refrigerator frequently, so that the articles are matched with higher storage priority weight. Of course, it is also possible to match lower priority for storing items with longer accumulated storage time according to personal habits or other factors.
Fourth embodiment
In the method for managing food materials in a refrigerator according to the fourth embodiment of the present invention, the difference between the method for managing food materials in a refrigerator and the third embodiment is that, in the present embodiment, according to the accumulated storage time of the articles in a preset time period, the method matches and stores priority weights for articles with storage times greater than a preset value, that is, deletes articles with storage times less than the preset value, so as to avoid that only one article is stored but the storage time is longer, which affects the accuracy of data. Referring to fig. 4, the refrigerator food material management method includes:
Identifying the type of the article in the refrigerator;
acquiring accumulated storage time and storage times of each article in a preset time period;
and matching and storing priority weights for the articles with the storage times larger than a preset value according to the accumulated storage time length.
The accumulated storage time length of the articles can include data with a single storage time length being greater than a storage time length threshold value, or can exclude data with a single storage time length being greater than a storage time length threshold value. The method for obtaining the storage times of the articles in the preset time period is referred to the first embodiment.
Matching and storing priority weights of articles stored for times larger than a preset value according to the accumulated storage time length, wherein the method comprises the following steps:
