Description

Technical Field

[0001] The present application relates to the technical field of smart home appliances, for example, to a method and device for refrigerator food management, a refrigerator, and a computer-readable storage medium. Background Art

[0002] At present, centralized procurement has become a new lifestyle for people, and the refrigerator, as a food safe, has become an essential household item. However, it is difficult for a refrigerator to identify the types and quantities of food ingredients inside, making it difficult to manage food ingredients. This can easily lead to users forgetting about expired food ingredients, and the refrigerator is also difficult to control the cooling capacity according to the types and quantities of food ingredients, resulting in low intelligence.

[0003] Related technologies disclose a refrigerator with a food ingredient management function. The refrigerator uses the principle of infrared thermal imaging. Essentially, it measures the temperature of food ingredients through infrared thermal sensing to determine whether the temperature of the food ingredients is higher than the set temperature of the refrigerator. If it is higher, the compressor is started for refrigeration.

[0004] Its so-called identification of food ingredient types only identifies the two-dimensional contour of food ingredients. When food ingredients are stacked or bagged, it will not be able to display the accurate contour of the food ingredients, let alone accurately identify the types and quantities of food ingredients.

[0005] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in related technologies:

[0006] Infrared radar technology mainly realizes the identification of food ingredient types through the contour and infrared spectrum of food ingredients. In addition to being unable to accurately distinguish food ingredients with similar shapes such as apples, pears, oranges, etc., when the temperatures of food ingredients are similar or food ingredients are stacked, the recognition accuracy and precision will also be greatly reduced, and this problem cannot be solved through algorithms.

[0007] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to those of ordinary skill in the art.

[0040] Combined Figures 1 to 4 As shown, the embodiment of the present disclosure provides a device for refrigerator food management, which is arranged in the refrigerating chamber of the refrigerator and is provided with: a first millimeter-wave radar detection system 1, a first numerically controlled slide rail system 2, a second millimeter-wave radar detection system 3, and a first data slide rail system 4.

[0041] The first millimeter-wave radar detection system 1 is used for transmitting and receiving millimeter-wave signals. The first numerically controlled slide rail system 2 is connected to the first millimeter-wave radar detection system 1 and is used for carrying the first millimeter-wave radar detection system to move on the first side of the refrigerating chamber. The second millimeter-wave radar detection system 3 is used for transmitting and receiving millimeter-wave signals. The first data slide rail system 4 is connected to the second millimeter-wave radar detection system 3 and is used for carrying the second millimeter-wave radar detection system to move on the second side of the refrigerating chamber. The first side and the second side are opposite to each other.

[0042] By using the device for refrigerator food management provided by the embodiment of the present disclosure, the first millimeter-wave radar detection system 1 is carried by the first numerically controlled slide rail system 2 to move on the first side of the refrigerating chamber, and the second millimeter-wave radar detection system 3 is carried by the second numerically controlled slide rail system 4 to move on the second side of the refrigerating chamber opposite to the first side, so as to realize the detection of all refrigerating compartments in the refrigerator. And because the first millimeter-wave radar detection system 1 and the second millimeter-wave radar detection system 3 move along the first numerically controlled slide rail system 2 and the second numerically controlled slide rail system 4, and emit millimeter-wave signals to the food materials at different positions in the refrigerating chamber and receive the millimeter-wave signals reflected by the food materials in the refrigerating chamber, which is equivalent to emitting and receiving millimeter-wave signals from a large-aperture antenna and can be equivalent to a synthesized large-aperture antenna, thereby reducing the cost of refrigerator food management and improving the detection accuracy and data accuracy of food management.

[0043] It can be understood that the first millimeter-wave radar detection system 1 and the second millimeter-wave radar detection system 3 are oppositely arranged and move synchronously on the opposite sides of the refrigerating chamber, so that the detection ends of the two are oppositely arranged and move synchronously on the opposite sides of the refrigerating chamber.

[0044] Optionally, the frequency of the millimeter-wave signals transmitted and received by the first millimeter-wave radar detection system 1 is in the frequency band of 76 GHz to 81 GHz. The frequency of the millimeter-wave signals transmitted and received by the second millimeter-wave radar detection system 1 is in the frequency band of 76 GHz to 81 GHz.

[0045] In this way, oxygen molecules and water molecules in the air have weak absorption of microwaves in the 76 GHz to 81 GHz frequency band. Therefore, the attenuation of microwaves in this frequency band in the air is small, and the transmission distance is farther, which is conducive to reducing the cost of refrigerator food management and improving the detection accuracy and data accuracy of food management.

[0046] Optionally, the moving directions of the first millimeter-wave radar detection system 1 and the second millimeter-wave radar detection system 3 are vertical in the refrigerating chamber. In this way, it is beneficial to detect the food in each separated storage area in the vertical direction of the refrigerating chamber with multiple separated storage areas.

[0047] Of course, in the scenario of being applied to a refrigerating chamber with multiple separated storage areas in the horizontal direction, the moving directions of the first millimeter-wave radar detection system 1 and the second millimeter-wave radar detection system 3 are horizontal in the refrigerating chamber.

[0048] In this way, it is beneficial to detect the food in each horizontally separated storage area.

[0049] Optionally, the first millimeter-wave radar detection system and / or the second millimeter-wave radar detection system includes: a millimeter-wave antenna module and a radar chip cascading module. The millimeter-wave antenna module is used to transmit millimeter-wave signals to the food in the refrigerating chamber and receive the millimeter-wave signals reflected by the food in the refrigerating chamber. The radar chip cascading module is electrically connected to the millimeter-wave antenna module and is used to transmit millimeter-wave signals to the millimeter-wave antenna module and receive the millimeter-wave signals sent by the millimeter-wave antenna module.

[0050] In this way, the first millimeter-wave radar detection system 1 and / or the second millimeter-wave radar detection system 3 includes a millimeter-wave antenna module and a radar chip cascading module. It can transmit millimeter-wave signals to the food at different positions in the refrigerating chamber and receive the millimeter-wave signals reflected by the food in the refrigerating chamber, which is equivalent to transmitting / receiving millimeter-wave signals from a large-aperture antenna on the first side and / or the second side of the refrigerating chamber, and can be equivalent to a synthetic large-aperture antenna on the first side and / or the second side of the refrigerating chamber, thereby reducing the cost of refrigerator food management and improving the detection accuracy and data accuracy of food management.

[0051] Optionally, the length of the millimeter-wave antenna module is less than the widths of the first side and the second side of the inner wall of the refrigerating chamber.

[0052] In this way, it is beneficial to make the millimeter-wave antenna module slide more smoothly in the horizontal direction on the first side and the second side of the refrigerating chamber, thereby improving the detection accuracy and data accuracy of food management.

[0053] Optionally, in combination with Figure 3As shown in the figure, the first millimeter-wave radar detection system 1 includes: a first millimeter-wave antenna module 11 and a first radar chip cascading module 12.

The first radar chip cascading module 12 is electrically connected to the first millimeter-wave antenna module 11 and is used to transmit millimeter-wave signals to the first millimeter-wave antenna module 11 and receive the millimeter-wave signals sent by the first millimeter-wave antenna module 11.

[0054] In this way, transmitting millimeter-wave signals to the food materials at different positions in the refrigerator compartment and receiving the millimeter-wave signals reflected by the food materials in the refrigerator compartment is equivalent to transmitting and receiving millimeter-wave signals from a large-aperture antenna, which can be equivalent to a synthetic large-aperture antenna, thereby reducing the cost of refrigerator food material management and improving the detection accuracy and data accuracy of food material management.

It is equivalent to transmitting / receiving millimeter-wave signals from a large-aperture antenna on the first side of the refrigerator compartment, and can be equivalent to a synthetic large-aperture antenna on the first side of the refrigerator compartment, thereby reducing the cost of refrigerator food material management and improving the detection accuracy and data accuracy of food material management.

[0057] Optionally, the first numerically controlled slide rail system 2 includes: a first numerically controlled slide rail 21 and a first numerically controlled slider 22.

It is equivalent to transmitting and receiving millimeter-wave signals from a large-aperture antenna on the first side of the refrigerator compartment, and can be equivalent to a synthetic large-aperture antenna on the first side of the refrigerator compartment, thereby reducing the cost of refrigerator food material management and improving the detection accuracy and data accuracy of food material management.

[0059] Optionally, the length of the first numerically controlled slide rail 21 is less than the height of the first side of the inner wall of the refrigerator compartment.

[0060] In this way, it is beneficial to better set the first numerically controlled slide rail 21 on the first side of the refrigerator's refrigerating chamber.

Specifically, the value of the set distance can be 1 mm.

[0062] In this way, it is beneficial to more precisely move the first millimeter-wave radar detection system 1 on the first side of the refrigerating chamber, so as to more evenly emit millimeter-wave signals to the food at different positions in the refrigerating chamber and receive the millimeter-wave signals reflected by the food in the refrigerating chamber. It is equivalent to emitting and receiving millimeter-wave signals from a large-aperture antenna on the first side of the refrigerating chamber, and a synthetic large-aperture antenna can be more precisely realized equivalently on the first side of the refrigerating chamber, thereby reducing the cost of refrigerator food management and improving the detection accuracy and data accuracy of food management.

[0066] Optionally, as shown in Figure 4 The second millimeter-wave radar detection system 3 includes: a second millimeter-wave antenna module 31 and a second radar chip cascading module 32. The second millimeter-wave antenna module 31 is used to emit millimeter-wave signals to the food in the refrigerating chamber and receive the millimeter-wave signals reflected by the food in the refrigerating chamber.

[0079] Combined Figure 5 As shown, an embodiment of the present disclosure provides a method for refrigerator food material management, including:

[0080] S501, the refrigerator controls the first millimeter-wave radar detection system and the second millimeter-wave radar detection system to detect and scan the refrigerating chamber, and respectively obtains a first transceiver signal set and a second transceiver signal set.

[0081] S502, the refrigerator determines the types and quantities of the food materials in the refrigerating chamber according to the first transceiver signal set and the second transceiver signal set.

[0082] By using the method for refrigerator food management provided in the embodiments of the present disclosure, since the first millimeter-wave radar detection system and the second millimeter-wave radar detection system detect and scan the refrigerating chamber along the first numerically controlled slide rail system and the second numerically controlled slide rail system, emit millimeter-wave signals to the food materials at different positions in the refrigerating chamber, and receive the millimeter-wave signals reflected by the food materials in the refrigerating chamber, the first transceiver signal set and the second transceiver signal set are respectively obtained. This is equivalent to emitting and receiving millimeter-wave signals from a large-aperture antenna and can be equivalent to synthesizing a large-aperture antenna. Then, according to the first transceiver signal set and the second transceiver signal set, the types and quantities of the food materials in the refrigerator refrigerating chamber are determined, thereby reducing the cost of refrigerator food management and improving the detection accuracy and data accuracy of food management.

[0083] Optionally, the refrigerator controls the first millimeter-wave radar detection system and the second millimeter-wave radar detection system to detect and scan the refrigerating chamber, and respectively obtains the first transceiver signal set and the second transceiver signal set, including: the refrigerator controls the first millimeter-wave radar detection system and the second millimeter-wave radar detection system to move to the same height together for the i-th time. The refrigerator successively controls the first millimeter-wave radar detection system and the second millimeter-wave radar detection system to emit and receive millimeter-wave signals for the i-th time, so as to successively obtain the corresponding i-th group of first transceiver signal sets and the i-th group of second transceiver signal sets. Wherein, i is a natural number.

[0084] In this way, first control the first millimeter-wave radar detection system and the second millimeter-wave radar detection system to synchronize to the same height, and then successively emit and receive millimeter-wave signals to obtain the first transceiver signal set and the second transceiver signal set, and repeat this process to scan each compartment of the refrigerating chamber. This is beneficial to better equivalent to synthesizing a large-aperture antenna, reducing the cost of refrigerator food management and improving the detection accuracy and data accuracy of food management.

[0085] Optionally, the refrigerator successively controls the first millimeter-wave radar detection system and the second millimeter-wave radar detection system to emit and receive millimeter-wave signals for the i-th time, so as to successively obtain the corresponding i-th group of first transceiver signal sets and the i-th group of second transceiver signal sets, including: the refrigerator controls the first millimeter-wave radar detection system to emit and receive millimeter-wave signals for the i-th time to obtain the corresponding i-th group of first transceiver signal sets. The refrigerator controls the second millimeter-wave radar detection system to emit and receive millimeter-wave signals for the i-th time to obtain the corresponding i-th group of second transceiver signal sets.

[0086] In this way, each time the first millimeter-wave radar detection system is controlled to first transmit and receive millimeter-wave signals to obtain a corresponding first set of transceiver signals, and then the second millimeter-wave radar detection system is controlled to transmit and receive millimeter-wave signals to obtain a corresponding second set of transceiver signals. This helps to avoid mutual interference when the first millimeter-wave radar detection system and the second millimeter-wave radar detection system transmit and receive millimeter-wave signals, making the obtained first set of transceiver signals and second set of transceiver signals more accurate, thus better equivalent to a synthetic large-aperture antenna, reducing the cost of refrigerator food management and improving the detection accuracy and data accuracy of food management.

The refrigerator determines the types and quantities of the ingredients in the refrigerating chamber according to the millimeter-wave three-dimensional image.

[0088] In this way, first constructing the millimeter-wave three-dimensional image and then determining the types and quantities of the ingredients in the refrigerating chamber according to the millimeter-wave three-dimensional image helps the obtained first set of transceiver signals and second set of transceiver signals to be more accurate, thus better equivalent to a synthetic large-aperture antenna, reducing the cost of refrigerator food management and improving the detection accuracy and data accuracy of food management.

[0089] Optionally, the refrigerator constructs a millimeter-wave three-dimensional image according to the first set of transceiver signals and the second set of transceiver signals, including: The refrigerator performs superposition processing on the i-th group of the first set of transceiver signals and the i-th group of the second set of transceiver signals to obtain the i-th two-dimensional superposition signal set. The refrigerator constructs a millimeter-wave three-dimensional image by using N two-dimensional superposition signal sets. Wherein, N is the number of scans of the first millimeter-wave radar detection system and the second millimeter-wave radar detection system in each compartment of the refrigerating chamber.

[0090] In this way, the signal intensities of the i-th group of the first set of transceiver signals and the i-th group of the second set of transceiver signals are negatively correlated. If the first millimeter-wave radar detection system is closer to the ingredients in the refrigerator, the signal intensity of the first set of transceiver signals is stronger and the resolution is better. At this time, the second millimeter-wave radar detection system is farther from the ingredients in the refrigerator, and the signal intensity of the second set of transceiver signals is relatively poor. When the i-th group of the first set of transceiver signals and the i-th group of the second set of transceiver signals are superposed and processed, the best types and quantities of the ingredients in the refrigerator refrigerating chamber can be obtained. This helps to improve the detection accuracy and data accuracy of food management.

[0091] Optionally, the determination method of N is: The refrigerator determines N according to the distance L between the first millimeter-wave antenna module and the second millimeter-wave antenna module. Specifically, N = L / L0. The value of L0 can be 4 cm.

[0092] In this way, determining N according to the distance L between the first millimeter-wave antenna module and the second millimeter-wave antenna module is beneficial to taking into account the data quality and data volume of each cold storage compartment, which helps reduce the cost of refrigerator food management and improve the detection accuracy and data accuracy of food management.

[0093] Optionally, the refrigerator constructs a millimeter-wave three-dimensional image by using N two-dimensional superimposed signal sets, including: the refrigerator constructs a millimeter-wave three-dimensional image by using the amplitude, phase, and frequency of the transmitted and received signals of the N two-dimensional superimposed signal sets.

[0094] In this way, it is beneficial to obtain a millimeter-wave three-dimensional image more accurately.

[0095] Optionally, the refrigerator performs superimposition processing on the i-th group of first transceiver signal sets and the i-th group of second transceiver signal sets to obtain the i-th two-dimensional superimposed signal set, including: the refrigerator filters the i-th group of first transceiver signal sets and the i-th group of second transceiver signal sets to obtain the i-th group of first filtered signal sets and the i-th group of second filtered signal sets. The refrigerator performs superimposition processing on the i-th group of first filtered signal sets and the i-th group of second filtered signal sets to obtain the i-th two-dimensional superimposed signal set.

[0096] In this way, by filtering the first transceiver signal set and the second transceiver signal set first, the interference signals generated by the refrigerator itself can be directly filtered out, obtaining the first filtered signal set and the second filtered signal set absorbed and reflected by the food itself, and then superimposing the first filtered signal set and the second filtered signal set to obtain a two-dimensional superimposed signal set. This is beneficial to obtaining a millimeter-wave three-dimensional image more accurately.

[0097] Specifically, the refrigerator filters the i-th group of first transceiver signal sets and the i-th group of second transceiver signal sets, including: the refrigerator filters the i-th group of first transceiver signal sets and the i-th group of second transceiver signal sets respectively by combining power subtraction and power inversion to achieve filtering.

[0098] In this way, filtering is achieved by combining power subtraction and power inversion, directly filtering out the interference signals generated by the refrigerator itself, obtaining the first filtered signal set and the second filtered signal set absorbed and reflected by the food itself, and then superimposing the first filtered signal set and the second filtered signal set to obtain a two-dimensional superimposed signal set. This is beneficial to obtaining a millimeter-wave three-dimensional image more accurately.

[0099] Optionally, the refrigerator determines the types and quantities of the food in the cold storage compartment according to the millimeter-wave three-dimensional image, including: the refrigerator extracts the food feature information from the millimeter-wave three-dimensional image. The refrigerator determines the types and quantities of the food in the cold storage compartment according to the food feature information and the standard food feature information.

[0100] In this way, based on the ingredient feature information and standard ingredient feature information extracted from the millimeter-wave three-dimensional image, it is beneficial to more accurately determine the types and quantities of ingredients in the refrigerator, improving the detection accuracy and data accuracy of ingredient management.

[0101] Optionally, the ingredient feature information includes one or more of: ingredient distribution information, ingredient shape information, or dielectric constant.

[0102] In this way, the dielectric constant refers to the ability of a substance to hold electric charges, and the loss factor refers to the magnitude of energy loss due to the degree of dispersion of the substance. The coupling ability of a material with microwaves is usually represented by the tangent value of the loss angle. The larger the tangent value of the loss angle, the stronger the coupling ability of the material with microwaves. Different ingredients have different dielectric properties due to their different nutrient compositions and moisture contents, and at the same time, their sizes and shapes are also different, ultimately resulting in different reflections and absorptions of microwaves. Therefore, the ingredient distribution information, ingredient shape information, and dielectric constant can be used to determine the types and quantities of ingredients, improving the detection accuracy and data accuracy of ingredient management.

[0103] Optionally, the refrigerator determines the types and quantities of ingredients in the refrigerator according to the ingredient feature information and standard ingredient feature information, including: the refrigerator uses the ingredient feature information to match the corresponding target standard ingredient feature information in the standard ingredient feature information library. The refrigerator determines the types and quantities of ingredients in the refrigerator corresponding to the target standard ingredient feature information.

[0104] In this way, by matching the corresponding standard ingredient feature information in the standard ingredient feature information library through the ingredient feature information, the types and quantities of ingredients in the refrigerator are determined. This is beneficial to improving the detection accuracy and data accuracy of ingredient management.

[0105] Optionally, the standard ingredient feature information library is obtained in the following manner: The refrigerator performs detection scans on different ingredients with known types and quantities in the refrigerator. The refrigerator constructs a standard millimeter-wave three-dimensional image according to the first transceiver signal set and the second transceiver signal set. The refrigerator extracts ingredient feature information from the millimeter-wave three-dimensional image to obtain the standard ingredient feature information. The refrigerator stores the types and quantities of ingredients and the corresponding standard ingredient feature information to obtain the standard ingredient feature information library.

[0106] In this way, it is beneficial to better obtain the standard ingredient feature information, so as to more accurately match the ingredient feature information with the corresponding standard ingredient feature information in the standard ingredient feature information library, and further more accurately determine the types and quantities of ingredients in the refrigerator. This is beneficial to improving the detection accuracy and data accuracy of ingredient management.

First, a millimeter-wave three-dimensional image is constructed, and then the types and quantities of the food materials in the refrigerating chamber are determined based on the millimeter-wave three-dimensional image, which is beneficial to making the obtained first transceiver signal set and second transceiver signal set more accurate, so as to better be equivalent to a synthetic large-aperture antenna, reduce the cost of refrigerator food material management and improve the detection accuracy and data accuracy of food material management.

The determination module 702 is configured to determine the types and quantities of the food materials in the refrigerating chamber based on the first transceiver signal set and the second transceiver signal set.

[0115] By using the device 200 for refrigerator food management provided by the embodiments of the present disclosure, since the first millimeter-wave radar detection system and the second millimeter-wave radar detection system detect and scan the refrigerating chamber along the first numerically controlled slide rail system and the second numerically controlled slide rail system, emit millimeter-wave signals to the food materials at different positions in the refrigerating chamber, and receive the millimeter-wave signals reflected by the food materials in the refrigerating chamber to respectively obtain a first transceiver signal set and a second transceiver signal set, it is equivalent to emitting and receiving millimeter-wave signals from a large-aperture antenna, and can be equivalent to synthesizing a large-aperture antenna. Then, according to the first transceiver signal set and the second transceiver signal set, the types and quantities of the food materials in the refrigerator refrigerating chamber are determined, thereby reducing the cost of refrigerator food management and improving the detection accuracy and data accuracy of food management.
