Fig. 4 exemplarily shows a schematic diagram of a food material storage management process provided by the embodiment of the application, where the process may be executed by an intelligent refrigerator or a server. As shown, the process may include the following steps:
s401: obtaining the type and the quantity of food materials to be planned.
In some scenarios, if the refrigerator is planned for the first time (for example, the current refrigerator is empty), the food materials to be planned include all food materials that need to be put into the refrigerator. In other scenarios, if the user currently stores food materials into the refrigerator, the food materials to be planned include the food materials currently stored in the refrigerator by the user and the original food materials in the refrigerator, wherein the related information of the original food materials in the refrigerator can be stored in a food material database of the refrigerator. In other scenes, if the user takes out the food material from the refrigerator at present, the food material to be planned is the food material remaining in the refrigerator. The operation of the user for entering and exiting the food material into and out of the refrigerator can be determined by detecting an image shot by an internal or external camera of the refrigerator, or determined by other methods, such as obtaining a voice instruction for taking the food material or storing the food material through voice recognition.
The information of the food materials to be planned may include information of the type and quantity of the food materials to be planned. The number of food materials can be characterized by the weight of the food material, the volume of the food material (such as a box of 1000ml ice cream), other units such as a bundle of green vegetables, or the number of individual food materials such as 10 eggs.
In this step, the refrigerator may obtain information of the food material to be planned in various ways. For example, in some embodiments, the refrigerator may collect food materials accessed by the user to the refrigerator through an internal or external camera, perform image recognition by itself or request the server to perform image recognition, to determine the type of the food materials accessed by the user, further determine the number of the accessed food materials, or obtain the weight of the accessed food materials by combining with a weight sensor arranged in an interlayer of the refrigerator. In other embodiments, the graphic code recognizer disposed in the refrigerator can read the graphic code on the accessed food material package to obtain the information of the food material. In other embodiments, the RFID tag on the food packaging can also be read by an RFID reader to obtain the food material information. In other embodiments, the refrigerator may further obtain information of the food material through voice input and the like. The essence of the embodiment of the application is not affected by which way to obtain the relevant information of the food material to be planned.
If the server plans the storage position of the food material, the refrigerator sends a food material planning request to the server after obtaining the information of the food material to be planned, wherein the information of the food material to be planned is carried, so as to request the server to plan the storage position of the food material. The request comprises an address (such as a MAC address) of the refrigerator, the server can inquire the information registered in advance of the refrigerator through the address to obtain the model of the intelligent refrigerator, and therefore the specification information of the refrigerator is obtained according to the model, and the specification information specifically comprises information such as storage space inside the refrigerator. In some embodiments, the refrigerator model may also be sent to the server with the request.
In some embodiments of the application, when some parameters or internal storage structures of the refrigerator are changed, for example, a user adjusts the temperature in the refrigerating chamber, and the user adjusts the size of the partition layer, the refrigerator can send the current parameters of the refrigerator to the server in time, so as to serve as one of the bases for the server to plan the storage location of the food material.
S402: and determining the priority sequence of the food materials to be planned in each storage position of the refrigerator.
In this step, the storage conditions provided by each storage location in the refrigerator and the storage conditions required by the food materials to be planned can be obtained first; and then, determining the priority sequence of the food materials to be planned in each storage position of the refrigerator according to the matching degree between the storage conditions provided by each storage position in the refrigerator and the storage conditions required by the food materials to be planned.
The storage locations in the refrigerator are different due to their location distribution and structure, and there may be differences in the storage conditions that different storage locations can provide, for example, a refrigerating compartment partition can provide a refrigerating storage condition, and a freezing compartment drawer can provide a freezing storage condition. The storage conditions required for food materials may also be different according to the variety of the food materials, for example, some food materials need to be stored at a lower temperature in a frozen manner, and some food materials only need to be stored in a refrigerated manner. Therefore, the storage conditions required by one food material are respectively matched with the storage conditions provided by each storage position in the refrigerator, so that the matching degree of the food material and each storage position can be obtained, and the priority ranking of each storage position of the food material in the refrigerator can be further obtained. In determining a suitable storage location for the type of food material, a storage location with a high priority is preferentially assigned to the type of food material compared to a storage location with a low priority.
The storage conditions that can be provided by the storage location and the storage conditions required by the food material may include one condition, or may include a plurality of conditions of different dimensions, for example, the storage conditions that can be provided by the storage location and the storage conditions required by the food material include a temperature condition, a humidity condition, and an isolation condition, and may also include the size of the storage space. The temperature condition may be a temperature range, the humidity condition may be a humidity range, and the isolation condition may refer to a degree of enclosure of the storage space, such as open (e.g., a partition) or closed (e.g., a drawer).
In some embodiments, in order to calculate the priority, for a storage condition that can be provided by a storage location in the refrigerator, a requirement of each food material to be planned on the storage condition may be quantized into a matching degree value (one matching degree value corresponds to one storage condition and is used for indicating a degree of matching with the storage condition) respectively, so as to calculate a priority score of each food material with respect to the storage location, and a high or low priority score of one food material indicates a degree of matching between the food material and the storage location. The above calculation is performed for each storage location in the refrigerator, so that the matching degree of each food material to be planned with each storage location in the refrigerator can be obtained.
Specifically, n (n is an integer greater than or equal to 1) storage conditions provided by the storage location numbered 1 in the refrigerator are represented as (t)1，1，t1，2，t1，3，......，t1，n)。
For the storage condition provided for the storage location numbered 1, the storage condition matching value for the food material of the category q1 is represented as { r }1，1，r1，2，r1，3，......，r1，nAnd calculating the obtained score as:
S1＝r1，1×r1，2×r1，3×......×r1，n
for the storage condition provided for the storage location numbered 1, the storage condition matching value for the food material of the category q2 is represented as { r }2，1，r2，2，r2，3，......，r2，nAnd calculating the obtained score as:
S2＝r2，1×r2，2×r2，3×......×r2，n
if S is1＞S2This indicates that the food material of category q1 has a higher priority than the food material of category q2 for the storage location numbered 1, which storage location is to be preferentially allocated to the food material of category q 1.
For example, if the storage condition of the refrigerating compartment partition 1 in the refrigerator is (refrigerating temperature range of 3-5 degrees, open storage) and the storage condition of the freezing compartment drawer 1 is (freezing temperature of-5 degrees, closed storage), the food materials to be planned include "bottled chili sauce" and "quick-frozen dumpling". Wherein the matching degree value of the "bottled chili sauce" corresponding to the storage condition of the refrigerating compartment partition 1 is (100% ), the matching degree value corresponding to the storage condition provided by the freezing compartment drawer 1 is (0, 80%), the matching degree value of the "quick-frozen dumpling" corresponding to the storage condition of the refrigerating compartment partition 1 is (0, 50%), and the matching degree value corresponding to the storage condition provided by the freezing compartment drawer 1 is (100%, 50%). According to the information, the value of the bottled chilli sauce corresponding to the refrigerating chamber interlayer 1 is 1, and the value of the bottled chilli sauce corresponding to the freezing chamber drawer 1 is 0; the "quick-frozen dumplings" were scored 0 for the refrigerating compartment partition 1 and 1 for the freezing compartment drawer 1. Since the score of the "bottled chili sauce" corresponding to the refrigerating chamber partition layer 1 is higher than the score corresponding to the freezing chamber drawer 1, the refrigerating chamber partition layer 1 is preferentially selected when the food material is stored; since the score of the "quick-frozen dumplings" corresponding to the refrigerating compartment partition 1 is lower than the score corresponding to the freezing compartment drawer 1, the freezing compartment drawer 1 is preferentially selected when storing the food material.
In the embodiment of the present application, the storage condition provided at each storage location in the refrigerator may be preset. The design of the internal storage structures of the refrigerators in different models may be different, so that the storage conditions provided by the storage positions in the refrigerators in corresponding models can be set for the internal storage structures of the refrigerators in different models. Specifically, a refrigerator information database may be preset, and the database may record, for one or more types (models) of refrigerators, information related to storage conditions that can be provided by each storage location in the corresponding type of refrigerator, such as temperature, closed state, capacity, and the like.
In the embodiment of the present application, the storage condition requirements of different food materials may be preset, and specifically, a food material database may be preset, in which the storage condition requirements of various food material types and each food material are recorded.
Based on the refrigerator information database and the food material database, when the priority is calculated, the food material database can be inquired to obtain the storage condition requirements of the food materials to be planned, the storage conditions which can be provided by each storage position in the target refrigerator are obtained by inquiring the refrigerator information database, and the priority sequence of each storage position of each food material to be planned in the refrigerator is determined according to the mode.
It should be noted that the above calculation method of the storage location priority for a certain food material is only an example, and other calculation methods do not affect the essence of the present application.
S403: classifying the food materials to be planned according to the types and storage conditions of the food materials to be planned, and determining the priority sequence of the food materials in the food material classification.
The priority ranking of the food materials in one food material classification represents the priority ranking of the food materials in the food material classification which are stored in the appropriate storage position preferentially.
In this step, the food materials to be planned can be classified according to the weight of the food materials to be planned, the difference of storage conditions among different food materials, and whether the food materials can be stored together. For example, food materials with similar storage conditions and without mutual contraindications can be classified into one category, the food materials classified into one category can be stored together, categories with large storage condition differences are stored separately as much as possible, and the categories with mutual contraindications are stored to remind users of isolating storage. According to the method, the food materials can be classified into several large categories, such as seafood, meat, fruits and vegetables, quick-frozen foods and the like.
In this step, the process of determining the priority of the food materials in one food material classification in the food material classification may include: firstly, obtaining the score and the weight of each food material in the food material classification on at least one priority storage condition, then respectively determining the priority storage evaluation score of each food material according to the score and the weight of each food material in the food material classification on the at least one priority storage condition (for example, calculating by adopting a weighted summation algorithm), and finally determining the priority of the food materials in the food material classification according to the priority storage evaluation score of each food material in the food material classification, and further performing priority sequencing.
The priority storage condition may include one or a plurality of priority storage conditions with different dimensions, for example, user preferences, importance of food materials, and the like.
The scores of the food materials on the preferential storage conditions can be obtained through big data analysis or set by a user. The weight of a food material on each priority storage condition can be preset, and the value of the weight is not changed under the normal condition unless the weight is reset.
For example, in the same food material classification, the score of the food material 1 on the preferential storage condition "user taste" is 90, the score on the preferential storage condition "food material importance degree" is 10, the score of the food material 2 on the preferential storage condition "user taste" is 10, the score on the preferential storage condition "food material importance degree" is 90, the weight corresponding to the preferential storage condition "user taste" is 40%, and the weight corresponding to the preferential storage condition "food material importance degree" is 60%, the priority score of the food material 1 is equal to 42, and the priority score of the food material 2 is equal to 58, so in the food material classification, the priority of the food material 2 is higher than that of the food material 1, and when the food material is stored, the food material 2 is preferentially allocated a suitable storage position compared with the food material 1.
It should be noted that the above method of calculating the priority of each food material in a certain food material classification is only an example, and other calculation methods do not affect the essence of the present application.
S404: determining a prioritization of food material classifications.
The priority sequence of the food material classifications represents the priority sequence of the food materials to be planned to be stored in the appropriate storage positions in priority according to the food material classifications.
In this step, the score and the weight of each food material category on at least one priority storage condition may be first obtained, then, the priority storage evaluation score of each food material category is respectively determined (for example, calculated by using a weighted sum algorithm) according to the score and the weight of each food material category on at least one priority storage condition, and finally, the priority ranking of all food material categories is determined according to the priority storage evaluation score of each food material category.
The priority storage condition may include one or a plurality of priority storage conditions with different dimensions, for example, user preference, user requirement, and the like.
The score of one food material classification on each preferential storage condition can be obtained by big data analysis. The weight of one food material classification on each priority storage condition may be preset.
For example, when the score of the food material category 1 on the preferential storage condition "user taste" is 90, the score on the preferential storage condition "user requirement" is 10, the score of the food material category 2 on the preferential storage condition "user taste" is 10, the score on the preferential storage condition "user requirement" is 90, the weight corresponding to the preferential storage condition "user taste" is 40%, and the weight corresponding to the preferential storage condition "user requirement" is 60%, the priority score of the food material category 1 is equal to 42, and the priority value of the food material category 2 is equal to 58, so that the priority of the food material category 2 is higher than the priority of the food material category 1, and when storing food materials, the food material in the food material category 2 is preferentially assigned a suitable storage location compared to the food material in the food material category 1.
The above method of calculating the priority of each food material category is only an example, and other calculation methods do not affect the essence of the present application.
S405: and determining the appropriate storage position of the food material to be planned in the refrigerator according to the priority sequence of the food material classification, the priority sequence of the food materials in the food material classification, the priority sequence of the storage positions of the food material to be planned in the refrigerator and the number of the food materials.
In this step, the comprehensive priority ranking of each food material to be planned can be determined according to the priority and the weight of the food material classification in which the food material to be planned is located, and the priority and the weight of the food material classification in which the food material is located; and then, determining the appropriate storage position of the food materials to be planned in the refrigerator according to the comprehensive priority sequence of the food materials to be planned, the priority sequence of each storage position of the food materials to be planned in the refrigerator and the quantity of the food materials.
For example, the food material classification 1 includes M food materials (food material 1 to food material M), and the priority score of the food material classification 1 is C1The corresponding weight is L1The priority score of the food material i (i is more than or equal to 1 and less than or equal to M) in the food material classification is kiThe corresponding weight is L2If the integrated priority W of food material i is equal to C1＊L1+ki＊L2。
And calculating the comprehensive priority score of each food material in each food material classification according to the method, so that the comprehensive priority sequence of each food material can be obtained.
After the comprehensive priority or priority ranking of each food material is obtained through calculation, the appropriate storage position of the food material to be planned in the refrigerator can be determined according to the comprehensive priority ranking of each food material, the priority ranking of each storage position in the refrigerator and the number of the food materials. The method comprises the steps of firstly, determining the optimal storage position of food materials according to the priority ranking of the food materials at each storage position in a refrigerator, if the number of the food materials is large, and the remaining food materials still need to be stored after the optimal storage position is fully occupied, selecting the storage position with the second priority to be allocated to the food materials, and so on until the storage positions of all the food materials are allocated. And then selecting the food with the second comprehensive priority, and allocating the storage positions according to the mode until all the food to be allocated are allocated with the storage positions in full parts or until the refrigerator has no allocable storage positions.
It should be noted that the above method for determining the appropriate storage location of the food material in the refrigerator is only an example, and other calculation methods do not affect the essence of the present application.
