[0044] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0045] To facilitate the understanding of the embodiments of the present application, the following will be further explained and described in specific embodiments in connection with the drawings, and the embodiments do not constitute a limitation on the embodiments of the present application.

[0046] Figure 1 A flowchart of a control method of a storage equipment provided by the embodiment of the present application is shown in Figure 1 as shown, the method specifically includes:

[0047] S11. When the target object's hand is detected to enter the designated area corresponding to the storage device, obtain the hand's size information.

[0048] The control method for storage devices provided in this invention is applied to storage devices, including but not limited to: smart refrigerators, freezers, and lockers. The storage device may contain multiple compartments for storing items, and each compartment and each door of the locker can be individually controlled to open or close. When users retrieve beverages from the storage device at home, during gatherings with friends, when multiple users access the device simultaneously, or when shopping in a commercial environment, the method can match user identity based on hand size characteristics, accurately identify the needs of users with different identities, and control the corresponding door opening permissions. Compared to traditional single-door opening methods, this invention effectively avoids energy consumption such as cold air loss and provides a more efficient and convenient user experience.

[0049] In this embodiment, the storage device is equipped with a device for identifying hands entering a designated area. Specifically, an infrared detection device, such as an infrared ranging sensor array, can be installed on the front of the storage device, and a three-dimensional spatial coordinate system can be established through a top vertical ranging module. When a user approaches the storage device and extends their palm towards a preset designated area (for example, a circle with a radius of 10-30cm drawn with the center of the storage device as the origin, or a rectangular area 10-30cm in front of the storage device door, etc.), the system first performs a real-time scan using the infrared ranging sensor array installed on the front of the storage device to determine whether a hand is present in the designated area. This sensor array is typically an 8×8 dot matrix layout, covering a space of 10 to 30cm directly in front of the storage device, with a sampling frequency of 50 times per second. When the ranging values ​​of multiple consecutive pixels in the array fall within this range, the main control chip determines that a target object has entered the designated area. It identifies whether the object entering the designated area is the hand of the target object. If it is identified as a hand, it compares the detection results of different frames. If the object remains within the designated area in multiple consecutive sampling periods, it is confirmed that the object is a valid hand and not an accidental interference object.

[0050] Furthermore, for hand recognition within the designated area, the system identifies the palm contour. Since an open palm forms a relatively concentrated point cloud region in the array, the system employs a region clustering method to merge the effective distance values ​​of adjacent pixels into a single overall contour. To avoid gaps caused by finger gaps, the system smooths the contour and performs small-scale interpolation, thereby obtaining a more complete palm contour region.

[0051] After the identified palm region, the size information of the palm is obtained, which can include the maximum width, maximum length, maximum thickness, etc. of the palm, and can also include the opening angle between the five fingers, the interphalangeal distance, and the ratio of the palm to the fingers, etc. For example, the system automatically extracts the straight-line distance between the two farthest points, which corresponds to the maximum width of the palm opening. Since the sensor array is designed with a fixed field of view angle, this straight-line distance can be directly converted to the length value in real space, thereby obtaining the size information of the user's palm.

[0052] Optionally, to ensure stability, the system will perform statistical processing on the multiple size measurement results collected within a time window of about 0.5 seconds (about 25 frames of data), for example, taking the median or taking the average after removing the maximum / minimum value, to filter out jitter and accidental errors. If the palm size data remains within a stable range (e.g. fluctuation does not exceed 1 centimeter) within the specified time window, the system can confirm that the size information is valid data. If the data fluctuates too much or disappears instantaneously during detection, it is determined as invalid trigger and needs to be re-detected.

[0053] Optionally, after detecting that the hand enters the specified area, a camera or depth sensor installed at the front end of the storage device is called to capture images of the hand. The image capture includes synchronous capture of RGB color images and depth images, and the depth images can be used to obtain the spatial position relationship between the hand and the sensor. Subsequently, the system pre-processes the captured hand images, including noise filtering, edge enhancement, and key point recognition, to improve the accuracy of subsequent size calculation. The hand region is separated from the background by image segmentation algorithm; then the palm edge, finger joint position, and finger extension degree are identified by using the palm key point detection model. On this basis, the width, height, and span of the five fingers after opening of the palm, and other size information are calculated. To avoid errors caused by different angles or lighting conditions, three-dimensional coordinate information in the depth image can be combined for correction. For example, by measuring the distance from the center point of the palm to each finger tip, and combining the depth distance parameter between the hand and the camera, more accurate real size is obtained.

[0054] Through the above steps, the system can not only identify whether the user's palm enters the specified area, but also accurately obtain the size information of the user's palm opening, providing basic data for subsequent identity matching and storage device permission control.

[0055] S12, determining the identity information of the target object according to the size information.

[0056] In the embodiment, the identity information can represent the palm size and height age of the target object (for example, the identity information can include children, adults, and tall people (higher than 180 cm), and the identity information can be distinguished according to the hand size information). The different threshold ranges of the size information correspond to different identity information, and the threshold range of the hand size information corresponding to the identity information can be set as follows: the size information is described by the palm width, a vertical infrared distance measuring module is installed on the top of the refrigerator, the height of the user is measured in advance (for example, by calculating the distance from the top of the head to the refrigerator), and the ergonomics ratio (height x 0.11 ≈ maximum palm width) is used to determine the palm width corresponding to the user of different height, and the threshold range of the palm width is dynamically adjusted: for example, the identity information is children (height < 140 cm), the set palm opening size range interval is 5-15 cm; the identity information is adults (height is between 140-180 cm), the set palm opening size range interval is 10-20 cm; and the identity information is tall people (height > 180 cm), the set palm opening size range interval is 15-25 cm. After the above range interval is obtained, the threshold range is further adjusted according to the calculated range interval, for example, the small threshold range corresponding to children = (minimum value, minimum value + (maximum value-minimum value) % 3), the medium threshold range corresponding to adults = (minimum value + (maximum value-minimum value) % 3, maximum value-(maximum value-minimum value) % 3), and the large threshold range corresponding to tall people = (greater than (maximum value-(maximum value-minimum value) % 3)), wherein the minimum value and the maximum value refer to the minimum value and the maximum value of the range interval corresponding to the different identity information. For example, the adjusted small threshold range corresponding to children = (5, 8), the medium threshold range = (8, 12), and the large threshold range is greater than 12.

[0057] Specifically, when determining the identity information, the size information can be input into the identity recognition module of the storage device. The threshold range in which each size information currently locates is determined, and the identity information corresponding to the threshold range is determined.

[0058] S13, controlling the opening permission of the storage device according to the identity information.

[0059] In the embodiment, the permission information of the storage device corresponding to the user of different identity information is set in advance and stored in the permission management module, and the permission information corresponding to the current identity information is called from the permission management module of the storage device after the identity information is determined. The permission information represents the opening permission of the user to the storage device (for example, the storage area (compartment of the storage device) that can be opened by the current user), the function range of the storage device that can be operated by the user, the time limit for opening the storage device, and the like.

[0060] For example, some users are only authorized to access the public area in the storage device, while the administrator user can access all areas and compartments of the storage device and perform setting operations. After identifying the target object as a user with different identities, the system automatically generates a control strategy according to the corresponding permission information.

[0061] Secondly, according to the control strategy, it is determined whether the target object is allowed to perform the operation of opening the storage device. When the determination result is allowed, the control driving mechanism (such as an electric lock, a magnetic lock, or a mechanical lock core control unit) issues an unlocking instruction to unlock the door body, the drawer or the cover body of the compartment, so that the current user can realize the opening operation; when the determination result is not allowed, the system remains in a locked state, and at the same time, a prompt information (such as a warning sound through a buzzer, or a prompt of "insufficient permission" on the display screen) can be issued.

[0062] Optionally, only the opening permission of the door body can be opened, and the user needs to actively operate the door body to open it. After opening the opening permission of the door body, the door body can be actively controlled to open, for example, the electromagnetic lock of the door body that determines that the user has the opening permission will automatically release the lock, and at the same time, a miniature motor drives the door body to open.

[0063] Optionally, only the items used by the users with different identity information (such as beverages of different capacities and food materials of different sizes) can be stored in each compartment, and the opening permission of the compartment corresponding to the different identity information is set according to the type (different sizes and capacities) of the items stored in the compartment (for example, the opening permission of the compartment storing beverages with a capacity less than a first threshold value is opened for children, and the opening permission of the compartment storing beverages with a capacity greater than or equal to the first threshold value is opened for adults).

[0064] As an example, in the scenario of a family using a refrigerator in daily life, when a user takes a beverage from the refrigerator, the user only needs to stretch the palm flatly close to the recognition area on the door of the refrigerator, and the identity information of the current user is recognized according to the threshold range of the palm width. If the identity information is an adult who wants to take a 500ml bottle of mineral water, the palm naturally opens about 15cm (medium size range), the system automatically opens the medium-sized beverage compartment door (which is used to store the corresponding beverages, food, and other items of adults) after recognition, and the user can directly take out the beverage. While a child wants to take a 200ml can of small coke, the palm opens about 12cm (small size range), and the refrigerator only opens the small-sized beverage compartment (which is used to store the corresponding beverages, food, and other items of children), avoiding large-area loss of cold air.

[0065] Optionally, if the user is a temporary visitor, the system will allow him to open the device within a limited time period, and once the time range is exceeded, the permission will be automatically closed. If it is detected that the same identity continuously attempts to open the storage device multiple times within a short period of time, the system can determine that it is an abnormal operation, and automatically lock and trigger a safety alarm.

[0066] By the above manner, the storage equipment can realize fine and differentiated permission control based on the identity information of the target object, avoid unauthorized personnel from illegally opening the storage equipment, and thus improve the security and use management efficiency of the equipment.

[0067] The control method of the storage equipment provided by the embodiment of the present application can obtain the size information of the hand when detecting that the hand of the target object enters the specified area corresponding to the storage equipment, determine the identity information of the target object according to the size information, and control the opening permission of the storage equipment according to the identity information. Thus, the palm size feature can be matched with the user identity, the user demand of different identities can be accurately recognized, and the corresponding cabinet door opening permission can be controlled. Compared with the traditional whole door opening mode, the present application can accurately control the opening permission of part of the storage equipment, effectively avoid energy consumption such as cold air loss, and provide more efficient and convenient use experience.

[0068] Figure 2 The flowchart of another control method of the storage equipment provided by the embodiment of the present application is shown in FIG. 2, and the method specifically includes the following steps. Figure 2

[0069] S21, when detecting that the hand of the target object enters the specified area of the storage equipment and stays in the specified area for a time length greater than a first threshold, obtaining the maximum width and / or maximum height of the hand in the target palm state; and taking the maximum width and / or maximum height as the size information.

[0070] In the embodiment, the storage equipment is provided with a sensing module, for example, an infrared sensor, a depth camera, an ultrasonic sensor or a pressure sensor. When the hand of the target object enters the specified area near the storage equipment, the sensing module can capture the spatial position information of the hand in real time and determine whether the hand enters the specified area. When it is determined that the hand enters the specified area, the staying time length of the hand in the specified area is obtained. When it is detected that the staying time length of the hand is greater than a preset first threshold (for example, 0.5 seconds, 1 second or a configurable time value), it can be determined that the user does not enter the specified area unintentionally, but has an interaction intention. Thus, the false triggering caused by the instantaneous passing or accidental touch of the hand can be effectively reduced, and the accuracy of recognition is improved.

[0071] ​After confirming that the target object has an interaction intention, an image acquisition module (such as an RGB camera, a TOF depth camera, or a binocular camera) is controlled to acquire an image of the hand of the target object, and the current hand shape (for example, a fist or an open palm) is identified from the image. When the hand is in a target palm state, the maximum width and / or maximum height of the palm are acquired. To ensure consistency and accuracy of the identification, the hand can be prompted or guided to be in the target palm state (for example, the palm is spread open and faces the sensor, or the five fingers are naturally separated).

[0072] When it is identified that the hand is in the target palm state, the edge contour of the hand is extracted based on image recognition or sensor data, and the geometric features of the palm region are calculated as the size information. The maximum width generally corresponds to the farthest boundary distance of the palm in the horizontal direction, and the maximum height generally corresponds to the farthest boundary distance of the palm in the vertical direction (for example, the maximum width can be determined by detecting the pixel distance between the extreme points (the leftmost point and the rightmost point) of the edges of the two sides of the palm. The maximum height can be determined by detecting the pixel distance between the bottom of the palm and the tip of the middle finger). The maximum width, the maximum height, or a combination of the two can be selected as the final size information (for example, if the detected maximum width of the palm is 9.2 cm and the maximum height is 18.6 cm, the system will take these two values as the hand size information of the current target object).

[0073] Optionally, multiple frames of images or multiple sensor results are compared, and the stable maximum value is taken as the final size information to avoid data deviation caused by hand shaking or sensor noise.

[0074] S22, determine the identity information corresponding to the size information according to the threshold range in which the size information is located, and there is a corresponding relationship between the threshold range and the identity information; or, acquire the face information of the target object; determine the first identity information corresponding to the size information according to the threshold range in which the size information is located, and determine the second identity information corresponding to the face information; take the first identity information and the second identity information as the identity information.

[0075] In this embodiment, the hand size information and / or face information of the target user are comprehensively analyzed to accurately determine the identity information of the target object. Specifically, the following two methods are included:

[0076] Method one: only based on the size information to determine the identity information, a size information and identity information corresponding relationship table is maintained in the storage module in advance. When the detected size information falls within a certain preset threshold range, the user corresponding to the threshold range is taken as the first identity information (for example, the size information is the palm width of 7 cm, the threshold range is (5, 8), and the identity information corresponding to the threshold range is: children). The matched first identity information is taken as the identity information of the target object.

[0077] The second way is to determine the identity information based on the size information and the face information. The camera module is controlled to collect the face of the target object, and a face detection and recognition model is used to extract a feature vector, which is compared with the standard face features stored in the database to obtain second identity information. Specifically, a deep learning face recognition model can be used to calculate a similarity score. If the score is higher than a preset threshold (e.g., 0.8), it is considered that the matching is successful.

[0078] When the first identity information (based on the palm size) and the second identity information (based on the face information) are consistent, the identity is directly taken as the final identity information. When the two are inconsistent, a weight strategy can be used for judgment. For example, in a high-security scenario, the face recognition result is given priority; in a low-light or occlusion scenario, the palm size result is given priority; or both need to be matched at the same time before the verification is considered to be passed. Finally, the fused result is taken as the identity information of the target object for subsequent processing.

[0079] Optionally, when the first identity information cannot be recognized (e.g., the palm is not in the target palm state, or the size information cannot match any threshold range), the second identity information is used as the identity information, or when the second identity information cannot be recognized (e.g., the face image is not clear, and the similarity between the face image and the pre-stored identity information image is less than a set value, indicating that the user has not been stored in advance), the first identity information is used as the identity information. If both identity information are recognized, the first identity information is selected as the identity information.

[0080] Optionally, a highest-privilege user is pre-set and stored, which represents that the user has the opening permission for all the compartments of the storage device. When the face image of the user is recognized as the pre-set highest-privilege user, the second identity information is taken as the identity information, i.e., the identity information is determined as the highest-privilege user.

[0081] Through the above two ways, identity recognition can be flexibly completed in different scenarios. The palm size can be used to achieve fast and low-cost identity differentiation, which is suitable for home or office. In a storage device with high security requirements (such as a safe, a medicine cabinet, or a server cabinet), the joint verification of palm size and face recognition can significantly improve the accuracy and security of identity recognition, avoiding the risk of single biological feature being forged or misidentified.

[0082] S23, determine whether the identity information has the first opening permission of the storage device. If the determination result is yes, the storage device is controlled to open the first opening permission for the target object, and the target compartment corresponding to the target object is determined according to the identity information. The storage device has a plurality of compartments, and there is a corresponding relationship between the identity information and the compartments. The target compartment is controlled to open the second opening permission for the target object.

[0083] In the present embodiment, the first opening authority is used to open the door body of the storage device (e.g., multiple door bodies of a refrigerator), and the second opening authority is used to open the compartments (e.g., internal storage compartments of the refrigerator), each of which corresponds to a specific function or storage type (e.g., beverage small compartments, medium compartments, large compartments, or different compartment openings of a medicine cabinet).

[0084] It is preset whether each identity information has the first opening authority of the storage device, and the second opening authority of the compartments in the storage device possessed by each identity information.

[0085] Specifically, it is first determined whether the current identity information has the first opening authority. If the determination result is "no", the system keeps the overall locking state of the storage device, and a prompt (e.g., a buzzer prompt or a display screen displaying "no authority") can be triggered. If the determination result is "yes", the operation of opening the first opening authority is performed, that is, the main lock or the electromagnetic lock of the storage device is controlled to be unlocked, so that the storage device is in an operable state, and at this time the user can directly open the door body of the storage device.

[0086] After determining that the user has the first opening authority, the target compartment with the second opening authority possessed by the current identity information is obtained (e.g., the identity information is a child, the corresponding second opening authority is a small compartment, the identity information is an adult, the corresponding second opening authority is a medium compartment, the identity information is a tall person, the corresponding second opening authority is a large compartment, and the identity information is a high-privilege administrator who can access all compartments).

[0087] After determining the target compartment, the compartment lock (such as a miniature electromagnetic lock or a mechanical sliding rail lock) of the target compartment is controlled to be unlocked, and the second opening authority is opened for the target object so that it can operate to open the target compartment.

[0088] At the same time, the system can detect the target compartment door state through sensors or switches to ensure that the target compartment is automatically reset and locked after use, avoiding unauthorized access to other compartments.

[0089] As an example, in a family scenario, when an adult user stretches his hand close to the refrigerator, the system identifies that the identity has the first opening authority, and the main cabinet door is unlocked; then the target medium compartment is controlled to be unlocked according to the user's identity, so that it can directly take out 500ml mineral water, while the small and large compartments remain locked.

[0090] In a commercial scenario, in a beverage cabinet in a convenience store, the customer identity information corresponds to different capacity compartments, and the system automatically unlocks the target compartment according to the identity, and the other compartments remain locked, thereby avoiding cold air loss or misoperation.

[0091] Optionally, in combination with the time period control or the number of times limit, the security is further enhanced, for example, the temporary identity user is limited to access a specific compartment only once within a specified time period.

[0092] In the above manner, the embodiment realizes the hierarchical permission control based on the identity information: the first opening permission ensures the safe management of the entire storage device; and the second opening permission realizes the fine control of different compartments, improves the security and use efficiency, and avoids unauthorized compartment operation or resource waste.

[0093] In one possible implementation, when the door body of the storage device is multiple, the method further includes: obtaining coordinate information of the hand in the specified area; determining a target door body corresponding to the coordinate information, and judging whether the identity information has the opening permission of the target door body; if the judgment result is yes, controlling the target door body to open the opening permission for the target object; if the judgment result is no, and the identity information has the opening permission of other door bodies, then controlling the other door bodies to open the opening permission for the target object, and generating prompt information of the other door bodies for display.

[0094] In the embodiment, the storage device includes multiple independent door bodies (for example, a refrigerator includes four door bodies of upper left, upper right, lower left, and lower right), and each door body corresponds to a different storage compartment. To realize the accurate door opening control of the target object, the method includes the following steps:

[0095] When the hand of the target object enters the specified area of the storage device, the system obtains the coordinate information of the hand in the three-dimensional space through an infrared distance sensor array, a depth camera, or an ultrasonic sensor, which is used to represent which door body the hand is in front of. For example, a three-dimensional coordinate system in front of the storage device is established: the X-axis (horizontal direction) is used to distinguish the left and right position ranges of different door bodies; the Y-axis (vertical direction) is used to record the height of the hand; and the Z-axis (depth direction) is used to record the distance of the hand from the door body. Through the corresponding relationship between the space coordinate intersection and the door body position, it is determined which target door body is operated by the hand. The recognized identity information is compared with the permission information of the target door body to judge whether the identity information has the opening permission of the target door body.

[0096] If the judgment result is yes, the lock (electromagnetic lock or mechanical lock) of the target door body is unlocked, so that the target object obtains the opening permission of the door body, and thus can directly operate to open the target door body. If the judgment result is no, it is further judged whether the identity information has the opening permission of other door bodies: if the identity information has the opening permission of other door bodies, the door body with the opening permission is automatically selected, and the door body is controlled to be unlocked, and prompt information is generated (such as displaying “please use the right door body” on the display screen or indicating the available door body position through the light).

[0097] If no other door body permission is available, all door bodies are kept locked and a warning prompt (e.g. a buzzer prompt "no permission to operate") can be triggered.

[0098] Optionally, after determining that the user has the opening permission, the electromagnetic lock of the door body of the corresponding storage device or the door body of the compartment can be controlled by a relay. At the same time, a mechanical sliding rail design is adopted, so that the cabinet door will automatically pop open by 30 degrees under the assistance of a spring.

[0099] Optionally, when multiple hands are detected in the specified area, they are processed in turn according to the "first come, first served" principle with a 0.5-second interval. The palm position is located by an infrared array, and the hand of the user closest to the sensor is responded to preferentially. For example, two people stretch their hands into the specified area, and the system opens the opening permission of each palm in turn according to the order of entering the specified area.

[0100] As an example, there are three door bodies in the family beverage cabinet: the left door body for small beverage compartments, the middle door body for medium beverage compartments, and the right door body for large beverage compartments. A child user stretches his hand close to the middle door body, but the permission only allows the left door body to be opened. After the system recognizes this, the left door body is unlocked, the middle door body remains locked, and a prompt "please use the small left door body" is displayed on the display screen or LED indicator. An adult user stretches his hand close to the middle door body and has the permission, so the middle door body is directly unlocked, allowing the user to get the medium beverage.

[0101] As an example, a three-dimensional coordinate system is established on the front of the storage device: X-axis (horizontal): distinguished by left and right partition sensors (left area 0-40 cm, right area 40-80 cm), Y-axis (vertical): height measured by a top distance measuring module (130-200 cm divided into 3 intervals), Z-axis (depth): palm distance from the door body measured by an infrared array (10-30 cm is the effective recognition zone), when a user stretches his hand, the system determines a unique user through the intersection of the space coordinates. For example: detecting (X: 25 cm, Y: 165 cm, Z: 20 cm) locks a right area operation of an adult user, that is, the target door body is the right door body of the storage device.

[0102] This embodiment realizes precise door opening control of a multi-door body storage device: the door body operated by the user's hand can accurately correspond to its identity permission, realizing safe unlocking of the target door body; in the case of insufficient permission, the system can intelligently guide the user to the operable door body, avoiding misoperation and loss of cold air; in the multi-door body and multi-user scenario, the safety and efficiency of operation sequence and permission management are ensured.

[0103] In one possible implementation, when it is detected that the number of hands of the object contained in the specified area is greater than a second threshold value and the duration is greater than a third threshold value, the opening permission of the storage device is controlled to be: continuously opening the opening permission of all door bodies and all compartments.

[0104] In this embodiment, the storage device supports the scenario of multiple users operating simultaneously. When the system detects that the number of hands contained in the specified area exceeds the second threshold (for example, 2 or 3 hands), and the hands stay in the specified area for a duration that exceeds the third threshold (for example, 2 seconds or 3 seconds), the system will trigger the gathering mode, thereby controlling the storage device to open the global permission. That is, when the number of people and the stay time conditions are met, the opening permission of the control storage device is in a continuous open state.

[0105] In this mode, all door bodies and all compartments of the storage device are unlocked, so that each user can freely access any door body and compartment without the need for individual identity or hand size matching. At the same time, the system can prompt that the current is in the gathering mode through the display screen, indicator light or sound, reminding the user that the storage device is in an open state.

[0106] As an example, in the scenario of a friend gathering, different users may require different capacities of beverages. For example, someone wants to take a 330ml beer (small size), and someone wants to take a 1L large bottle of juice (large size) and at the same time stretch out the hand to appear in the specified area. The system identifies the palm size of multiple users, automatically opens the gathering mode, and controls the opening permission of the storage device to be in a continuous open state.

[0107] This embodiment realizes automatic global unlocking control in the scenario of multiple people operating: automatically identifies multiple hands entering and stay time, realizes fast response to the operation demand of multiple people; all door bodies and compartments are continuously opened in the gathering mode, improving the use efficiency.

[0108] In one possible implementation, when it is detected that the environmental volume in the target space is less than the fourth threshold, and the specified area does not contain any object hand, the opening permission of the control storage device is: closing the opening permission of all door bodies and all compartments; or, when it is detected that the environmental volume in the target space is greater than the fifth threshold, the number of hands of the objects contained in the specified area is greater than the second threshold, and the duration is greater than the third threshold, the opening permission of the control storage device is: continuously opening the opening permission of all door bodies and all compartments.

[0109] In this embodiment, the storage device can dynamically adjust the unlocking permission according to the ambient sound volume in the target space (room) and the number of hands in the specified area, realizing intelligent and automatic management. The specific steps are as follows: an ambient sound volume collection module (such as a microphone array) is arranged near the storage device to monitor the sound intensity in the target space in real time. The volume data is measured in decibels (dB), and through filtering and noise elimination algorithm, the stable ambient sound volume value is obtained. When it is detected that the ambient sound volume in the target space is lower than the fourth threshold value (for example, 30dB, indicating a quiet environment), and the specified area does not contain any object's hand, the system determines that no one is currently operating the storage device. The control storage device closes the opening permission of all door bodies and all compartments, locks the door body, and prevents misoperation.

[0110] When it is detected that the ambient sound volume in the target space is greater than the fifth threshold value (for example, 70dB, indicating a gathering or multi-person operating environment), the gathering mode can be directly triggered to continuously open the opening permission of all door bodies and all compartments. Or, when it is detected that the ambient sound volume in the target space is greater than the fifth threshold value, and the number of hands of the objects contained in the specified area is greater than the second threshold value (such as 2 hands), and the hands stay in the specified area for a time greater than the third threshold value (such as 2 seconds), the system determines that there is a demand for multi-person active operation, triggers the gathering mode, and controls the storage device to continuously open the opening permission of all door bodies and all compartments, meeting the demand of multiple people taking at the same time. At the same time, it can be prompted through the display screen or the indicator light that the current is in the gathering mode, ensuring that the user knows the device state. For example, in the living room, the ambient sound volume exceeds 70dB, and three users are detected to stretch their hands and approach the cabinet door at the same time, the system automatically opens all door bodies and compartments, facilitating multiple people to take beverages.

[0111] This embodiment realizes the automatic opening and closing control of the storage device under the combination of environmental perception and user interaction: automatically closing the door body and the compartment in a quiet environment to improve energy saving and safety; automatically opening all door bodies and compartments in a multi-person active operation or high-volume environment to improve the convenience and efficiency of use; balancing safety, energy saving and use experience, realizing intelligent storage management.

[0112] Figure 3 Another flowchart of a control method of a storage device provided by an embodiment of the present application is shown in FIG. 8, which specifically includes the following steps. Figure 3

[0113] ​Start: the process is started. User's palm is close: it is detected that the user's palm is close to the device. Infrared array scanning: the device scans the palm by using the infrared array. Calculate the maximum palm distance: the maximum span (palm distance) of the user's palm is calculated through the scanning data. Size judgment: the palm size is judged according to the calculated palm distance. If the result corresponds to the small size range, the small cabinet door is opened; if the result corresponds to the medium size range, the medium cabinet door is opened; if the result corresponds to the large size range, the large cabinet door is opened. Complete operation: after the cabinet door is opened, the process is ended. Thus, the palm size is determined by the infrared scanning, different specifications of cabinet doors are opened, the non-contact and intelligent control mode of the opening permission of the storage equipment door body and the compartment is realized, and the user experience is improved.
