Detailed Description
The following describes a specific implementation of an intelligent refrigerator according to an embodiment of the present invention in detail with reference to the accompanying drawings. It should be noted that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides an intelligent refrigerator, as shown in fig. 1, which may include:
a code scanner 10;
a distance measuring sensor 20;
a processor 30 configured to:
determining a first time at which the code scanner 10 scans the identification code on the food material;
determining a second time when the ranging sensor 20 measures that the user passes through the measurement area of the ranging sensor 20;
determining the access action of the user according to the first time and the second time; the access operation comprises the following steps: the food materials are stored in the intelligent refrigerator and taken out of the intelligent refrigerator.
So, through installing bar code scanner and range sensor in intelligent refrigerator, can determine the bar code and scan the very first time of the identification code on the edible material to and the range sensor measures the second time when the user passes through the measuring area, and at this moment, the treater can be according to very first time and second time, accurately determines user's access action, also promptly: determining whether the user stores the food material into the intelligent refrigerator or takes the food material out of the intelligent refrigerator; therefore, the influence of information such as surface smoothness and color of food materials is eliminated, the identification accuracy and the identification efficiency of access actions are effectively improved, and effective data reference is provided for the management of the food materials in the refrigerator.
In specific implementation, in the embodiment of the present invention, as to the arrangement manner of the code scanner and the ranging sensor, the following manner may be further included:
mode 1:
optionally, in an embodiment of the present invention, as shown in fig. 2, the intelligent refrigerator includes: a refrigerator door 40 and a cabinet 50;
the code scanner 10 and the ranging sensor 20 are located on the same layer (not shown) in the partition layer included in the refrigerator door, and/or the code scanner 10 and the ranging sensor 20 are located on the same layer in the partition layer a included in the refrigerator body 50 (as shown in fig. 2, the code scanner 10 and the ranging sensor 20 are not limited to be located on the left side of the partition layer a, and may also be located on the right side of the partition layer a);
ranging sensor 20 is located on a side of scanner 10 that is closer to the interior of housing 50 (as shown in the enlarged partial view of FIG. 2, scanner 10 obscures ranging sensor 20 from view, to indicate that ranging sensor 20 is closer to the interior of housing 50).
Therefore, when the access action of the user is determined, the access logic of the user can be met, the thinking habit of the user is met, the user does not need to access food materials according to a certain special requirement when using the intelligent refrigerator, the food materials can be accessed according to ordinary thinking resources, convenience is provided for the user, and meanwhile the access action can be recognized.
Specifically, in the embodiment of the present invention, the distance between the code scanner and the ranging sensor is smaller than the preset value.
The preset value may be set according to actual needs, and is not limited herein.
Namely: bar code scanner and range sensor set up closely for the user is taking out the edible material from intelligent refrigerator and is wanting to sweep the sign indicating number on the bar code scanner, must be through range sensor's measuring area, and perhaps, the user wants to deposit edible material and takes edible material to sweep the sign indicating number on the bar code after, must also can pass through range sensor's measuring area.
It is to be noted that, when a user takes out a food material, the process of scanning a code and taking out the food material is required, and assuming that a time of scanning the code (i.e., a time when the code scanner scans an identification code) is t, if it is detected that the food material or a hand of the user passes through a measurement area of a distance measurement sensor before the time (e.g., t- Δ t), the food material can be determined to be taken out according to this logic;
when the user stores the food material, assuming that the code scanning time is t, before (e.g. t- Δ t) the food material is not detected or the hand of the user passes through the measuring area of the distance measuring sensor, and after (e.g. t + Δt) the food material is detected or the hand of the user passes through the measuring area of the distance measuring sensor, determining that the food material is stored;
the time interval (i.e. Δ t) between the time of scanning the code and the time when the food or the user's hand passes through the measuring area of the distance measuring sensor is short, i.e. Δ t can be small.
For example, if the time when the barcode scans the identification code is t1, the time when the ranging sensor detects that the user passes through the measurement area is t2, the moving speed of the hand of the user in the process of accessing the food material is v, the distance between the barcode and the ranging sensor is d, and if the time when the barcode acquires the identification code and the response time of the ranging sensor are ignored, then:
t1-t2＝△t＝d/v；
where v may be about 1m/s and d may be about 5cm, Δ t may be about 50ms.
Therefore, the non-inductive identification of the access action can be realized, namely, when a user accesses food materials, the code scanning operation only needs to be completed at the corresponding position, and the intelligent refrigerator can complete the management of the access action.
In addition, the access action of the user can be determined only by the thinking habit of the user without special regulation on the access action of the user, so that the difficulty of identifying the access action is simplified, and the efficiency of identifying the access action is improved.
In addition, the method and the device can be beneficial to improving the identification accuracy of the access action of the user, and avoid the phenomenon that the time length between the first time and the second time is longer due to the fact that the distance between the code scanner and the ranging sensor is too far away, so that misjudgment is avoided.
Specifically, in an embodiment of the present invention, the processor is configured to:
when the first time is prior to the second time, determining that the user stores food materials into the intelligent refrigerator;
when the first time is later than the second time, determining that the user takes out the food materials from the intelligent refrigerator;
and the time difference between the first time and the second time is less than the preset time.
The preset time mentioned here can be understood as Δ t mentioned above.
That is to say, since the ranging sensor is located at one side of the barcode scanner close to the interior of the refrigerator body, if the barcode scanner scans the identification code first and then the ranging sensor detects that the user passes through the measurement area, it can be determined that the user stores the food material into the intelligent refrigerator; if the ranging sensor detects that the user passes through the measuring area firstly, and then the code scanner scans the identification code firstly, it can be determined that the user takes the food material out of the intelligent refrigerator.
Therefore, the access action of the user can be determined according to the first time and the second time, and effective data reference is provided for the management of food materials.
Of course, in particular when the ranging sensor is located on the side of the barcode remote from the interior of the cabinet, the processor may also be configured to:
when the first time is later than the second time, determining that the user stores the food materials into the intelligent refrigerator;
and when the first time is prior to the second time, determining that the user takes the food material out of the intelligent refrigerator.
That is, the access action of the user may be determined based on the set positions of the barcode scanner and the ranging sensor, and in combination with the sequence of the first time and the second time.
Specifically, when the number of the sets of the code scanners and the ranging sensors is set, the following cases may be included:
case 1:
optionally, in the embodiment of the present invention, there is one each of the code scanner and the ranging sensor, and the illustration is not given.

Therefore, the number of the coders and the distance measuring sensors can be effectively reduced, the manufacturing cost of the intelligent refrigerator is further reduced, and meanwhile, the identification of the access action of a user can be realized.
Case 2:
optionally, in an embodiment of the present invention, there is one code scanner, and there are multiple distance measuring sensors;
the intelligent refrigerator includes: the refrigerator door and/or the refrigerator body comprise a plurality of interlayers;
a distance measuring sensor, not shown, is provided in each compartment.
Wherein the code scanner can be arranged in any interlayer.
Therefore, the number of the coders can be effectively reduced, the manufacturing cost of the intelligent refrigerator is reduced to a certain degree, and meanwhile, the identification of the access action of a user can be realized.
Case 3:
optionally, in the embodiment of the present invention, a plurality of code scanners and a plurality of ranging sensors are provided;
and a code scanner and a distance measuring sensor are arranged in each interlayer.
So, can monitor and analyze the access of the edible material in every interlayer, realize the effective control to each position in the intelligent refrigerator.
In short, in the implementation, when the number of the scanners and the ranging sensors is set, any one of the cases 1, 2, and 3 may be adopted, and may be selected according to actual needs, which is not limited herein.
Mode 2:
alternatively, in the present embodiment, the code scanner 10 and the distance measuring sensor 20 are located on different layers, as shown in fig. 3, the code scanner 10 is located on the layer, and the distance measuring sensor 20 is located on the layer b.
In this embodiment 2, the positions where the code scanner 10 and the ranging sensor 20 are installed are not limited to those shown in fig. 3, but are described only by way of example in fig. 3.
So, can set up according to actual need the position of code scanner and range sensor to improve the flexibility of design, satisfy the needs of different application scenarios.
Specifically, in this mode 2, the access action of the user may be determined based on the settings of the code scanner and the ranging sensor, and in combination with the sequence of the first time and the second time; the specific implementation manner can be seen in the example in the above mode 1, and is not described in detail here.
Specifically, in this mode 2, when the number of the code scanners and the distance measuring sensors is set, the number can be set as needed at will, as long as the code scanners and the distance measuring sensors are ensured to be in different interlayers.
In summary, when the positions of the code scanner and the ranging sensor are set, reference may be made to any one of the above-described modes 1 and 2, and the positions may be specifically selected according to actual needs, and are not limited herein.

the user can hold the apple to scan the code scanner (marked as code scanner a) in the interlayer a, so that the code scanner a can scan the identification code on the apple;
when the code scanner a scans the identification code, the code scanner a can send a message carrying the identification code and the self identification to the processor;
when the processor receives the message, the processor can determine that the code scanner a scans the identification code, and further determine that the interlayer stored in the apple corresponding to the scanned identification code is the interlayer a.
That is to say, the storage positions of the food materials can be realized by distinguishing the identifiers of the code scanners, each interlayer which needs to be managed by a user is provided with the code scanner, when the user accesses the food materials in a certain interlayer, the user needs to scan the code of the code scanner of the corresponding interlayer, and the food materials after being scanned are placed in the interlayer corresponding to the code scanner; the processor can distinguish the access position of the food material by analyzing the identifier of the code scanner and the corresponding table of the interlayer.

This is illustrated in connection with fig. 2 and 5.
If the user wants to store Qingdao beer in the first interlayer of the intelligent refrigerator, the actions of the user are as follows in sequence:
scanning codes on the code scanner of the first interlayer;
placing Qingdao beer into the first interlayer.
In the execution process of the actions, when a user scans a code on a code scanner (marked as code scanner 1) in a first interlayer, the code scanner 1 can acquire an identification code of Qingdao beer and transmit the acquired identification code and an identifier of the code scanner 1 to a decision layer;
the processor in the decision layer can determine that the type of the food material is Qingdao beer by analyzing the identification code, and then determines that the code scanner 1 is positioned in the first interlayer according to the identification;
the user firstly scans the code and then stores the code, the ranging sensor is positioned on one side of the code scanner close to the interior of the box body, and if the time for the code scanner to acquire the identification code and the response time of the ranging sensor are ignored, the moment when the code scanner acquires the identification code is earlier than the moment when the ranging sensor is blocked (namely the ranging sensor detects that the user passes through a measuring area or can be understood as whether the hand of the user is close to the ranging sensor), so that the decision layer can judge that the user just moves to store Qingdao beer into the first interlayer;
the interaction layer can pop up a picture storing Qingdao beer in the first interlayer on the display, and/or voice broadcast 'storing Qingdao beer in the first interlayer', and visually presents information of storing and taking food materials for a user.
To illustrate, a smart refrigerator may generally include: the food material fresh-keeping system comprises a refrigerating chamber and a freezing chamber, wherein the refrigerating chamber can be used for carrying out fresh-keeping storage on food materials, so the requirement on the fresh-keeping degree of the food materials is high, and according to the characteristics of the food materials, the rotten time of the food materials is different even if the food materials are stored in the refrigerating chamber (namely, if green vegetables are short in storage time and easy to rot, and fruits such as apples are relatively long in storage time), so the refrigerating chamber is very necessary for managing the food materials;
it is to be noted that in the cold storage compartment, in addition to the compartment, drawers may be included, so that in each drawer, a barcode scanner and a distance measuring sensor may be provided as well.
The freezer compartment is used for freezing and storing food materials, and the food materials can be preserved for a long time without rotting, so that the freezer compartment is obviously less necessary for managing the food materials than the refrigerator compartment.
Based on this, the food management such as the determination of the access action, the determination of the type of the food material, and the determination of the storage location of the food material mentioned in the embodiments of the present invention may be applied only to a refrigerating chamber (as shown in fig. 2), or applied to a refrigerating chamber and a freezing chamber.
Of course, when being applicable to the freezer, need consider the behavior of bar code scanner and range sensor under low temperature environment, unable normal during operation under low temperature environment, can consider to improve bar code scanner and range sensor to make bar code scanner and range sensor can adapt to low temperature environment.

the preset time in S602 and S605 may be set to be the same or different, and may be set according to actual needs, so as to improve design flexibility and meet the needs of different application scenarios.
S606, determining the access action of the user as taking out food materials from the intelligent refrigerator; s604 is performed.
It is emphasized that, in the process of scanning codes by a user, no matter whether the scanned codes are stored or taken out, the hand of the user is close to the code scanner, and the difference is the sequence of the close to the code scanner and the blocking of the ranging sensor;
after the ranging sensor detects that the food materials are blocked at the moment t, whether a code scanning result exists within the time of t-delta t, t can be judged, if the code scanning result exists, the food materials scanned within the time of t-delta t, t can be considered as the food materials currently stored in the intelligent refrigerator by the user; because the delta t can be set to be smaller, a plurality of interference signals can be well filtered, the time boundary of code scanning and storing in food materials is easy to distinguish, most of misjudgments can be eliminated, and the accuracy of access action identification is improved;
the distance measuring sensor detects that the distance measuring sensor is blocked, no code scanning result exists in the time [ t-delta t, t ], at the moment, delta t multiplied by n (wherein n can be but is not limited to 1) can be waited, if the code scanning result exists in the time [ t, t +. DELTA t multiplied by n ], the food materials scanned in the time [ t, t +. DELTA t multiplied by n ] can be considered as food materials taken out of the intelligent refrigerator by a user, and if the code scanning result does not exist in the time [ t, t +. DELTA t multiplied by n ], the triggering that the distance measuring sensor is blocked can be ignored.
