Description

Technical Field

[0001] This application relates to the field of storage device technology, such as a door switch control device, storage device and control method for a storage device. Background Technology

[0002] With the development of technology, existing products and equipment are trending towards intelligence and user-friendliness to facilitate user operation. For example, a refrigerator door control method has been proposed in related technologies. This control method can determine whether the target object is attempting to open the refrigerator door when a target object is detected in a designated target area of ​​the refrigerator; when it is determined that the target object is attempting to open the door (such as when there is a touch operation on the door), it generates an assist command for the door to assist the target object in opening the refrigerator door.

[0003] In implementing the above embodiments, at least the following problems were found in the related technology:

[0004] While the technology can improve the convenience of opening the refrigerator to some extent, this sensor-triggered opening method requires users to interact with the refrigerator using different body parts or their full language abilities. For people with physical difficulties, such as those with limb disabilities or speech impairments, this sensor-triggered opening method has limited applicability.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides a door opening and closing control device, storage device, and control method for a storage device, which can improve the applicability of the door opening induction triggering method and the convenience of door opening and closing.

[0008] In some embodiments, a door opening / closing control device for a storage device is provided, comprising: a housing including an air inlet, a mounting cavity, and an exhaust outlet, wherein the air inlet and the exhaust outlet are both connected to the mounting cavity; a pressure sensor disposed in the mounting cavity and located between the air inlet and the exhaust outlet; a vibration unit disposed in the mounting cavity; and a controller disposed in the mounting cavity and communicatively connected to the pressure sensor and the vibration unit, for generating a corresponding door opening / closing signal based on the pressure value detected by the pressure sensor and controlling the vibration unit to vibrate according to a preset vibration rule.

[0009] The door opening and closing control device for storage devices provided in this disclosure includes a pressure sensor that detects the air pressure value in the mounting cavity between the air inlet and outlet. Based on this air pressure value, a corresponding door opening and closing signal is generated to trigger the door opening sensor. Simultaneously, based on the air pressure value, a vibration unit is controlled to vibrate according to a preset vibration rule to alert the user that the door opening sensor has been triggered. The door opening sensor triggering method provided in this disclosure only requires the user to breathe and have vibration sensing capabilities; simply blowing air is sufficient to trigger the door opening sensor. No physical actions or verbal interaction are required, thus broadening its applicability. Furthermore, by eliminating complex physical actions or verbal interaction, the door opening sensor triggering method is significantly simpler.

[0010] Optionally, the door opening and closing control device for the storage device further includes: a display unit disposed in the housing and communicatively connected to a pressure sensor and / or a controller.

[0011] In this embodiment, the display unit is communicatively connected to the air pressure sensor and / or controller, and is used to display content related to the air pressure value according to the air pressure value detected by the air pressure sensor and a preset display rule, so as to enable the user to operate the control device, improve the user's ease of use and enhance the user experience.

[0012] In some embodiments, a storage device is provided, including: a housing; a plurality of doors pivotally disposed in the housing; and a door opening and closing control device for the storage device as described in the above embodiments, installed in the housing and communicatively connected to the doors.

The control method includes: obtaining a pressure value detected by a pressure sensor; determining a target sub-pressure range in which the pressure value is located; and controlling a target door corresponding to the target sub-pressure range to perform an opening and closing action.

[0017] This disclosure provides a control method that only requires the user to breathe and exhale so that the air pressure sensor can detect the air pressure value, thereby enabling the door to open or close automatically. No physical actions or verbal interaction are required, thus making it applicable to a wider range of people. Furthermore, since complex physical actions or verbal interaction are omitted, the automatic opening or closing of the door is more convenient.

[0018] Optionally, the control method further includes: obtaining target parameters; the target parameters include the user's retrieval height and / or the opening frequency of multiple doors; sorting multiple doors according to the target parameters to obtain a door sequence; and associating multiple doors with multiple pressure zones according to the door sequence.

[0019] In this embodiment, the door sequence is generated based on the user's item retrieval height and / or the opening frequency of multiple doors, i.e., the user's own conditions and / or storage device usage habits. Therefore, it can enhance the user's personalized user experience and improve the user's storage device usage experience.

[0020] Optionally, the control method further includes: obtaining the user's physiological parameters; determining the total pressure range based on the user's physiological parameters; and dividing the total pressure range into multiple sub-pressure ranges based on the number of doors.

[0021] In this embodiment, the pressure range that meets the personalized needs of each user can be set according to the specific conditions (physiological parameters of the user), thus making it applicable to different users and further improving the applicability and reliability of the control method.

[0022] Optionally, the control method further includes: obtaining the user's vibration perception; determining the vibration rules corresponding to multiple partial pressure ranges based on the user's vibration perception; and controlling the vibration unit to vibrate according to the vibration rules corresponding to the target partial pressure range.

[0023] In this embodiment, vibration rules corresponding to multiple pressure ranges can be specifically set according to the user's vibration perception, so that the vibration unit can vibrate according to the vibration rules corresponding to the target pressure range and interact with the user. Since vibration perception varies from person to person, by incorporating the user's vibration perception to set specific vibration rules, the user's personalized experience is further enhanced.

[0024] Optionally, obtaining the user's vibration perception includes: obtaining the user's physiological parameters; correcting the initial vibration frequency based on the user's physiological parameters; and using the corrected initial vibration frequency as the user's vibration perception.

[0025] In this embodiment, the initial vibration frequency can be corrected according to the user's physiological parameters to obtain a vibration frequency that meets the user's personalized needs as the user's vibration perception, thereby indicating the user's sensitivity to vibration stimulation.

[0026] Optionally, the door opening and closing control device for the storage device further includes a display unit communicatively connected to a pressure sensor and / or controller; the control method further includes: obtaining the user's visual acuity parameters; determining display rules corresponding to multiple sub-pressure ranges based on the user's visual acuity parameters; and controlling the display unit to display according to the display rules corresponding to the target sub-pressure range.

[0027] In this embodiment, display rules corresponding to multiple partial pressure ranges can be specifically set according to the user's vision parameters, so that the display unit can display according to the display rules corresponding to the target partial pressure range and interact with the user. Since vision parameters vary from person to person, by incorporating the user's vision parameters to set specific display rules, the user's personalized experience is further enhanced.

[0054] Combination Figure 1 and Figure 4As shown, this embodiment of the present disclosure provides a door opening and closing control device 10 for a storage device, including a housing 100, a pressure sensor 120, a vibration unit 140, and a controller 160. The housing 100 includes an air inlet 102, a mounting cavity 104, and an exhaust port 106, both of which are connected to the mounting cavity 104. The pressure sensor 120 is disposed in the mounting cavity 104 and located between the air inlet 102 and the exhaust port 106. The vibration unit 140 is disposed in the mounting cavity 104. The controller 160 is disposed in the mounting cavity 104 and is communicatively connected to the pressure sensor 120 and the vibration unit 140, and is used to generate a corresponding door opening and closing signal based on the pressure value detected by the pressure sensor 120 and control the vibration unit 140 to vibrate according to a preset vibration rule.

[0055] The door opening and closing control device 10 for storage devices provided in this embodiment (hereinafter referred to as control device 10) uses a pressure sensor 120 to detect the air pressure value in the mounting cavity 104 between the air inlet 102 and the exhaust port 106. Based on this air pressure value, a corresponding door opening and closing signal is generated to trigger the door opening sensor. Simultaneously, based on the air pressure value, the vibration unit 140 is controlled to vibrate according to a preset vibration rule to alert the user that the door opening sensor has been triggered. The door opening sensor triggering method provided in this disclosure only requires the user to breathe and have vibration sensing capabilities; simply blowing air is sufficient to trigger the door opening sensor. No physical actions or verbal interaction are required, thus broadening the applicability to a wider range of users. Furthermore, by eliminating complex physical actions or verbal interaction, the door opening sensor triggering method is much simpler.

[0056] In this embodiment of the disclosure, the control device 10 is communicatively connected to the storage device via the controller 160 to control the storage device to perform door opening and closing actions according to the door opening and closing signal it generates.

[0057] In this embodiment of the disclosure, combined with Figure 2 As shown, the pressure sensor 120 includes a resistance mesh 122 and a differential pressure sensor 124. The resistance mesh 122 is disposed in the mounting cavity 104, located between the air inlet 102 and the exhaust port 106. The differential pressure sensor 124 is disposed in the mounting cavity 104, located around the resistance mesh 122, and is used to detect the pressure difference between the two sides of the resistance mesh 122 to obtain the air pressure value.

[0058] When gas passes through the resistance mesh 122, the mesh generates corresponding resistance based on the gas flow rate and pressure. The differential pressure sensor 124 is a device for measuring the pressure difference between two points, typically consisting of two pressure sensors installed at the two points to be measured (e.g., opposite sides of the resistance mesh 122). When gas passes through the resistance mesh 122, a pressure difference is generated on both sides due to its presence. The two pressure sensors in the differential pressure sensor 124 detect the pressure on both sides of the resistance mesh 122 and convert these pressure values ​​into electrical signals. These two electrical signals are subtracted and amplified by the differential amplifier circuit built into the differential pressure sensor 124, and then converted into digital-to-analog signals by the analog-to-digital converter (ADC) built into the differential pressure sensor 124. The magnitude of this signal is proportional to the pressure difference on both sides of the resistance mesh 122, reflecting the gas pressure value and thus enabling the acquisition of the gas pressure value.

[0059] In some embodiments, combined with Figure 3 As shown, the controller 160 incorporates a wireless communication unit 162. The controller 160 communicates with the storage device via the wireless communication unit 162. The wireless communication unit 162 includes a Wi-Fi (Wireless Fidelity) module and / or an NFC module. The Wi-Fi module is a transmission conversion product; it allows for data transmission and communication via the internet. The NFC module is a near-field communication product; it enables near-field data transmission and communication. The Wi-Fi and NFC modules can be integrated into the same module to form the wireless communication unit 162, allowing the module program to establish communication between the controller 160 and the storage device via the Wi-Fi and / or NFC modules.

[0060] Optionally, combined Figure 1 As shown, the housing 100 also includes an airflow channel 108. The two opposite ends of the airflow channel 108 are respectively connected to the air inlet 102 and the mounting cavity 104.

[0061] In this embodiment, the airflow channel 108 is used to guide airflow to the pressure sensor 120 to improve the detection accuracy of the pressure sensor 120, thereby improving the control accuracy and reliability of the control device 10 and enhancing the user experience.

[0062] In some embodiments, the resistance mesh 122 is located at one end of the mounting cavity 104 near the airflow channel 108, and the plane of the resistance mesh 122 is perpendicular to the extension direction of the airflow channel 108 for air pressure detection.

[0063] In some embodiments, combined with Figure 1As shown, along the length of the housing 100, the housing 100 includes a first end 110 and a second end 112 disposed opposite to each other. An airflow channel 108 extends from the first end 110 toward the second end 112. And along the direction from the first end 110 toward the second end 112, the cross-sectional area of ​​the airflow channel 108 perpendicular to the length direction of the housing 100 gradually increases.

[0064] In this embodiment, along the direction from the first end 110 to the second end 112, the cross-sectional area of ​​the airflow channel 108 perpendicular to the length direction of the housing 100 gradually increases. As the cross-sectional area of ​​the airflow channel 108 increases, the gas velocity gradually decreases when the gas enters from the air inlet 102, and the pressure distribution becomes more uniform. This reduces turbulence and eddies in the airflow, enabling the pressure sensor 120 to detect pressure changes more accurately, further improving the control accuracy and reliability of the control device 10, and enhancing the user experience.

[0065] In some embodiments, combined with Figure 4 As shown, along the length of the housing 100, the housing 100 includes a first end 110 and a second end 112 disposed opposite to each other. An airflow channel 108 extends from the first end 110 toward the second end 112. Along the direction from the first end 110 toward the second end 112, the cross-sectional area of ​​the airflow channel 108 perpendicular to the length direction of the housing 100 is the same.

[0066] In this embodiment, the cross-sectional area of ​​the airflow channel 108 perpendicular to the length direction of the housing 100 is the same along the direction from the first end 110 to the second end 112, so that after the gas enters from the air inlet 102, it can quickly pass through the airflow channel 108 to reach the pressure sensor 120, so that the pressure sensor 120 can detect the pressure value, improve the response speed of the control device 10, and improve the user experience.

[0067] Optionally, combined Figure 3 As shown, the barometric pressure sensor 120 and the controller 160 communicate via I... 2 C-bus communication connection.

[0068] I 2 The C (Inter-Integrated Circuit) bus enables data transmission between devices via a bidirectional serial data line (SDA) and a serial clock line (SCL). In this embodiment, the pressure sensor 120 incorporates an electronic chip 126, which is equipped with a corresponding SDI (Serial Data Input) interface 128 and an SCL (Serial Clock Line) interface 130 for data transmission via I... 2 C-bus connection configuration with controller 160. 2The C bus has the advantages of high-speed data transmission, multi-device connectivity, and low power consumption, utilizing I... 2 The C-bus enables data transmission between the pressure sensor 120 and the controller 160, allowing the pressure sensor 120 to quickly transmit the detected pressure value to the controller 160, reducing data transmission delay and thus improving the response speed of the control device 10. 2 The C-bus allows multiple devices to connect to the same bus simultaneously, facilitating the expansion of the control device 10. Simultaneously, it reduces power consumption, extends the lifespan of the control device 10, and decreases energy consumption.

[0069] Among them, the pressure sensor 120 and the controller 160 are connected via I 2 During data transmission on the C-bus, SDA remains low. When data transmission between the pressure sensor 120 and the controller 160 stops, SDA transitions to high. During the SDA level transition, SCL remains low. When the SDA level transition is complete, SCL transitions to high.

[0070] Among them, I 2 The C bus is connected to the power input via a pull-up resistor. The pull-up resistor has a resistance of 4.7 kΩ.

[0071] Optionally, combined Figure 1 and Figure 4 As shown, the control device 10 also includes a display unit. The display unit is disposed in the housing 100 and is communicatively connected to the pressure sensor 120 and / or the controller 160.

[0072] In this embodiment, the display unit is communicatively connected to the pressure sensor 120 and / or the controller 160, and is used to display content related to the pressure value according to the pressure value detected by the pressure sensor 120 and a preset display rule, so that the user can operate the control device 10, improve the user's ease of use and enhance the user's experience.

[0073] Optionally, combined Figure 1 and Figure 4 As shown, the display unit extends along the length of the housing 100.

[0074] In this embodiment, the display unit is elongated and extends along the length of the housing 100 so that the user can observe the display screen and operate the control device 10, thereby further improving the user's ease of use.

[0075] Optionally, there are multiple display units, which are spaced apart on the outer wall of the housing 100.

[0076] In this embodiment, by increasing the number of display units, multiple display units are spaced apart on the outer wall of the housing 100 so that users can observe the display content from multiple angles, further improving the user's ease of use.

[0077] In some embodiments, the display unit includes an LCD (Liquid Crystal Display) screen and an OLED (Organic Light-Emitting Diode) screen.

[0078] In some embodiments, combined with Figure 3 As shown, the vibration unit 140 includes a vibration motor 142.

[0079] The vibration motor 142 is a device that converts electrical energy into mechanical vibration energy. It generates a vibration effect through the centrifugal force produced by the eccentric mass block inside the motor. In this embodiment, the vibration effect generated by the vibration motor 142 stimulates the user's tactile sense, enabling interaction and improving the ease of use and user experience of the control device 10.

[0080] Optionally, combined Figure 3 As shown, the vibration unit 140 includes a MOSFET and a vibration motor 142 connected to each other. The controller 160 is connected to the gate of the MOSFET, the vibration motor 142 is connected to the drain of the MOSFET, and the source of the MOSFET is grounded.

[0081] A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a field-effect transistor based on a metal-oxide-semiconductor structure. A MOSFET mainly consists of a gate, a source, and a drain. MOSFETs are characterized by low power consumption and high reliability, making them effective in communication and information processing fields for information transmission. In this embodiment, the controller 160 controls the MOSFET to drive the vibration motor 142.

[0082] In some embodiments, combined with Figure 3As shown, the vibration unit 140 also includes a first resistor, a second resistor, a third resistor, a fourth resistor, and a diode. The two ends of the first resistor (R1) are connected to the controller 160 and the gate of the MOSFET, respectively, to limit the current flowing into the gate and prevent the MOSFET from burning out. The second and third resistors are pull-down resistors. One end of the second resistor (R2) is connected to the controller 160 and the first resistor, and the other end is grounded to stabilize the circuit signal. One end of the third resistor (R3) is connected to the source of the MOSFET, and the other end is grounded to limit the current and prevent excessive current from flowing through the MOSFET. One end of the diode is connected to the drain of the MOSFET, and the other end is connected to the fourth resistor. The fourth resistor and the diode are connected in series and in parallel with the vibration motor 142, forming a voltage regulator circuit to ensure the stable operation of the vibration motor 142.

[0083] In some embodiments, combined with Figure 3 As shown, the controller 160 includes a microcontroller unit (MCU). The MCU's GPIO (General-Purpose Input / Output) pins are connected to the gates of MOSFETs to control the MOSFETs, thereby driving the vibration motor 142. Specifically, when the output signal of the GPIO pin is high, the vibration motor 142 is driven, as shown... Figure 5 As shown.

[0084] In this application, the controller 160 is disposed in the mounting cavity 104. The placement described herein is not limited to its location within the mounting cavity 104, but also includes its connection to other components of the control device 10, including but not limited to physical connections, electrical connections, or signal transmission connections. Those skilled in the art will understand that the controller 160 can be adapted to feasible door opening / closing control devices 10 for storage devices, thereby enabling other feasible embodiments.

[0085] In some practical applications, the door switch control device 10 for storage devices can be configured on a necklace or bracelet so that the user can carry it with them.

[0086] In some embodiments, combined with Figure 6 As shown, a storage device 1 is provided, including a housing 20, a plurality of doors 30, and a door opening and closing control device 10 for the storage device as described in the above embodiment. The plurality of doors 30 are pivotally mounted on the housing 20. The door opening and closing control device 10 for the storage device is mounted on the housing 20 and is communicatively connected to the doors 30.

[0087] In this embodiment, the storage device 1 refers to an electronic product formed by integrating microprocessor, sensor technology, and network communication technology. It has the characteristics of intelligent control, intelligent sensing, and intelligent application. The operation of the storage device 1 often relies on the application and processing of modern technologies such as the Internet of Things, the Internet, and electronic chips. For example, the storage device 1 can be connected to the door switch control device 10 for storage devices described in the above embodiment to enable users to remotely control and manage the storage device 1.

[0088] The storage device 1 provided in this embodiment can control the opening or closing of multiple doors 30 using the control device 10 described in the above embodiment. Specifically, it can communicate with the storage device 1 via the Internet, or it can communicate directly with the storage device 1 via Bluetooth, Wi-Fi, or other means to control the opening or closing of multiple doors 30.

[0089] Furthermore, since the storage device 1 described in this embodiment includes the door switch control device 10 for the storage device described in the above embodiments, the technical effects of the door switch control device 10 for the storage device described in the above embodiments are all present in this embodiment, and will not be repeated here.

[0090] In this embodiment, the door 30 can automatically open or close based on the door opening / closing signal generated by the control device 10. The automatic opening or closing of the door 30 can be achieved through an ejection mechanism composed of a motor, a push rod, and terminals. When the door 30 needs to be opened, the ejection motor operates, driving the push rod to rotate. The push rod gradually rotates out from the terminal, separating the door 30 from the housing 20. When the door 30 needs to be opened again, the ejection motor operates in the opposite direction, driving the push rod to rotate. The push rod gradually rotates back from the terminal, closing the door 30 and housing 20 again. The automatic opening or closing of the door 30 can also be achieved by installing an electromagnet and a magnet on the door 30 and housing 20 respectively. By changing the direction of the current flowing through the electromagnet, an attractive or repulsive force is generated between the electromagnet and the magnet, thus closing or opening the door 30. This application does not limit the specific implementation method of the automatic opening or closing of the door 30.

[0091] In some embodiments, the storage device 1 includes a refrigeration device. The refrigeration device includes a refrigerator or freezer.

[0092] Refrigerators or freezers are essential household appliances for storing and preserving food. In this embodiment, by applying the aforementioned door switch triggering method to refrigerators or freezers, the applicability and ease of use of refrigerators or freezers are improved, enhancing the user experience.

[0093] Optionally, combined Figure 11 As shown, the controller 160 also includes a processor 164. The processor 164 can obtain the air pressure value detected by the air pressure sensor; can determine the target sub-pressure range where the air pressure value is located; and can control the target door corresponding to the target sub-pressure range to perform opening and closing actions.

[0094] Combination Figure 7 The present disclosure provides a method for controlling a storage device, as shown in the figure, including:

[0095] S701, the processor obtains the air pressure value detected by the barometer.

[0096] S702, the processor determines the target sub-pressure range where the air pressure value is located.

[0097] S703, the processor controls the target door corresponding to the target air pressure range to perform opening and closing actions.

[0098] In the control method for the storage device provided in this disclosure, there is a corresponding relationship between the air pressure range and the door. This allows the corresponding target door to be controlled to perform an opening and closing action by determining the target air pressure range in which the air pressure value is located. This achieves the generation of a corresponding door opening and closing signal based on the air pressure value, thereby controlling the door of the storage device to open or close. The control method provided in this disclosure only requires the user to breathe and exhale so that the air pressure sensor can detect the air pressure value, thereby realizing the automatic opening or closing of the door. No physical actions or verbal interaction are required, thus making it applicable to a wider range of people. Furthermore, by omitting complex physical actions or verbal interaction, the automatic opening or closing of the door is much simpler.

[0099] Combination Figure 8 As shown, this disclosure provides another method for controlling a storage device, including:

[0100] S801, the processor obtains the target parameters.

[0101] The target parameters include the user's item retrieval height and / or the opening frequency of multiple doors.

[0102] User retrieval height refers to the height at which a user can conveniently or habitually retrieve items. The user retrieval height can be set by the user; it can also be based on the user's waist height; or it can be determined according to the user's height, such as H = mn, where m and n are the user's height and a height correction parameter, respectively, in centimeters, and n > 10. For example, n can be 20 cm, 25 cm, or 30 cm.

[0103] S802, the processor sorts multiple gates according to the target parameters to obtain a gate sequence.

[0104] In some embodiments, the target parameter includes the user's retrieval height. Based on the target parameter, multiple doors are sorted to obtain a door sequence, including: obtaining the absolute difference between the set height of the multiple doors and the user's retrieval height; and sorting the multiple doors in ascending order based on the magnitude of the absolute difference to obtain the door sequence.

[0105] In this embodiment, the door height can be obtained from the storage device's instruction manual. When the door height is within a certain range, the midpoint of that range is taken, and the absolute difference between this range and the user's retrieval height is calculated. This absolute difference represents the ease with which the user can retrieve items from the door; the smaller the difference, the easier it is to retrieve the items. Based on these absolute differences, multiple doors are sorted. The sorting principle is from smallest to largest difference, that is, doors whose height is closest to the user's retrieval height are first arranged to obtain a door sequence that matches the user's individual preferences.

[0106] In some embodiments, the target parameters include the opening frequencies of multiple doors. According to the target parameters, the multiple doors are sorted to obtain a door sequence, including: sorting the multiple doors from largest to smallest according to their opening frequencies to obtain the door sequence.

[0107] In this embodiment, the door opening frequency can be obtained based on the historical usage frequency of the storage device. The door opening frequency refers to the number of times each door is opened within a certain period, reflecting its usage frequency and the user's habits. A higher opening frequency indicates that the user is more accustomed to or frequently uses that door for retrieving and placing items. Based on these opening frequencies, multiple doors are sorted. The sorting principle is to proceed from largest to smallest difference, that is, first arranging the doors most frequently used by the user to obtain a door sequence that matches the user's personalization.

[0108] In some embodiments, the target parameters include the user's item retrieval height and the opening frequency of multiple doors. Based on the target parameters, the multiple doors are sorted to obtain a door sequence, including: obtaining the absolute difference between the set height of the multiple doors and the user's item retrieval height; standardizing the absolute difference and the door opening frequency; calculating the weighted average of the standardized absolute difference and the opening frequency; and sorting the multiple doors from largest to smallest according to the magnitude of the weighted average to obtain the door sequence.

[0109] In this embodiment, standardization refers to mapping the absolute difference and the door opening frequency to a value between 0 and 1. For example, for the door opening frequency, each opening frequency can be divided by the maximum value of all opening frequencies to obtain the standardized opening frequency. For the absolute difference, each absolute difference can be divided by the maximum value of all absolute differences to obtain the absolute difference ratio, and then 1 is subtracted from the absolute difference ratio to obtain the standardized absolute difference (in this embodiment, the sorting principle is from largest to smallest, and the absolute difference between the door setting height and the user's item retrieval height should be as small as possible. Therefore, during the standardization process, the absolute difference needs to be corrected to conform to the sorting principle. Correspondingly, if the sorting principle is from smallest to largest, then during the standardization process of the opening frequency, 1 needs to be subtracted from the opening frequency after dividing by the maximum opening frequency to correct the opening frequency to conform to the sorting principle).

[0110] After standardizing the absolute difference and the door opening frequency, a weighted average of the two is calculated to comprehensively consider the user's convenience in retrieving items from each door and user habits, thus obtaining a door sequence that meets the user's individual needs. It should be noted that the weighting ratio between the standardized absolute difference and the weighted average of the opening frequency can be set by the user or by technical personnel based on the actual product equipment and user information; this application does not impose any restrictions.

[0111] The S803 processor associates multiple gates and multiple pressure ranges based on the gate sequence.

[0112] S804, the processor obtains the air pressure value detected by the barometer.

[0113] S805, the processor determines the target sub-pressure range where the air pressure value is located.

[0114] S806, the processor controls the target door corresponding to the target air pressure range to perform opening and closing actions.

[0115] The control method for the storage device provided in this disclosure can sort multiple doors according to the user's retrieval height and / or the opening frequency of multiple doors to obtain a door sequence that conforms to the user's own conditions and / or storage device usage habits. Then, based on this door sequence, multiple doors and multiple air pressure zones are associated so that the corresponding doors can be opened or closed according to the air pressure values. Since the door sequence in this disclosure is generated based on the user's own conditions and / or storage device usage habits, it can improve the user's personalized user experience and the user's storage device usage experience.

[0116] For example, in combination Figure 6As shown, the storage device includes five gates: A, B, C, D, and E. The gates are sorted according to the target parameters to obtain the gate sequence A, B, E, D, and C.

[0117] Optionally, the control method for the storage device further includes: obtaining the user's physiological parameters; determining the total pressure range based on the user's physiological parameters; and dividing the total pressure range according to the number of doors to obtain multiple sub-pressure ranges.

[0118] Physiological parameters include parameters that characterize a user's health status, such as lung capacity, heart rate, age, respiratory rate, or blood pressure.

[0119] The total pressure range can be determined by online data query; experimental measurement based on the user's current health status; or by technicians setting a mapping table between physiological parameters and total pressure ranges in advance, and then querying the corresponding total pressure range in the mapping table according to the user's specific physiological parameters.

[0120] In this embodiment, a total pressure range that matches the user's individual needs can be determined based on the user's specific physiological parameters, i.e., health status parameters, thereby further enhancing the personalized user experience. In addition, since this embodiment can set a pressure range that meets the individual needs of each user based on their specific conditions, it can be applied to different users, thereby further improving the applicability and reliability of the control method.

[0121] After determining the total pressure range, it is divided into multiple sub-pressure ranges based on the specific number of gates. For example, if there are 5 gates and the total pressure range is [8, 25] cmH2O (cm water column), then the sub-pressure ranges are [8, 11.4) cmH2O, [11.4, 14.8) cmH2O, [14.8, 18.2) cmH2O, [18.2, 21.6) cmH2O, and [21.6, 25] cmH2O. The gate sequence is A, B, E, D, C. The correspondence between each gate and the sub-pressure range after association is shown in Table 1.

[0124] Combination Figure 9 As shown, this disclosure provides another method for controlling a storage device, including:

[0125] S901, the processor obtains the air pressure value detected by the barometer.

[0126] S902, the processor determines the target sub-pressure range where the air pressure value is located.

[0127] S903, the processor controls the target door corresponding to the target air pressure range to perform opening and closing actions.

[0128] S904, the processor obtains the user's vibration perception.

[0129] Vibration perception refers to a user's sensitivity to vibration stimuli.

[0130] Optionally, obtaining the user's vibration perception includes: obtaining the user's physiological parameters; correcting the initial vibration frequency based on the user's physiological parameters; and using the corrected initial vibration frequency as the user's vibration perception.

[0131] In this embodiment, the user's physiological parameters, such as heart rate, age, respiratory rate, or blood pressure, characterize the user's health status. Humans can perceive vibration frequencies ranging from 20 to 1000 Hz, with the most sensitive frequency around 250 Hz. This vibration frequency range or the most sensitive vibration frequency can be used as the initial vibration frequency. Then, the initial vibration frequency is adjusted based on the user's physiological parameters to obtain a vibration frequency that meets the user's personalized needs, serving as the user's vibration perception level to indicate their sensitivity to vibration stimuli.

[0132] Among them, the initial vibration frequency is corrected according to the user's physiological parameters. This can be achieved by technicians setting correction parameters in advance based on the physiological parameters.

[0133] In some embodiments, the user's vibration perception can also be determined through prior experiments.

[0134] The S905 processor determines the vibration rules corresponding to multiple pressure ranges based on the user's vibration perception.

[0135] The vibration rules include specific vibration frequency, vibration duration, and vibration amplitude settings, aiming to provide users with the most comfortable and appropriate vibration feedback under different air pressure ranges.

[0136] In some embodiments, vibration perception is a vibration frequency range. Determining vibration rules corresponding to multiple pressure ranges based on the user's vibration perception includes: determining multiple vibration frequency values ​​from the vibration frequency range based on the number of pressure ranges; associating each vibration frequency value with each pressure range to obtain the vibration rules corresponding to each pressure range.

[0137] In some embodiments, vibration perception is a vibration frequency value. Based on the user's vibration perception, vibration rules corresponding to multiple pressure ranges are determined, including: adjusting the vibration duration and / or vibration amplitude of the vibration frequency value to generate multiple sets of vibration rules; associating each set of vibration rules with each pressure range to obtain the vibration rules corresponding to each pressure range.

[0138] S906, the processor controls the vibration unit to vibrate according to the vibration rules corresponding to the target air pressure range.

[0139] The control method for the storage device provided in this disclosure can specifically set vibration rules corresponding to multiple partial pressure ranges based on the user's vibration perception, so that the vibration unit can vibrate according to the vibration rules corresponding to the target partial pressure range and interact with the user. Since vibration perception varies from person to person, by incorporating the user's vibration perception to set specific vibration rules, the user's personalized experience is further enhanced.

[0144] S104, the processor obtains the user's vision parameters;

[0145] S105, the processor determines the display rules corresponding to multiple air pressure ranges based on the user's vision parameters.

[0146] Display rules include parameters such as font size, color contrast, and brightness. Visual acuity parameters are inversely proportional to font size, color contrast, and brightness.

[0147] Specifically, the display rules corresponding to multiple pressure zones are determined based on the user's visual acuity parameters. This can be achieved by having a specialist pre-set the display rules for each visual acuity parameter, and then determining the corresponding display rules for each user's specific visual acuity parameters, thereby defining the display rules for multiple pressure zones. This application does not limit the specific setting principles, as long as the visual acuity parameters are inversely proportional to font size, color contrast, and brightness.

[0148] In some embodiments, the display rules corresponding to multiple air pressure zones can also be set by the user according to their own vision.

[0149] S106, the processor controls the display unit to display according to the display rules corresponding to the target pressure range.

[0150] The control method for the storage device provided in this disclosure can specifically set display rules corresponding to multiple partial pressure ranges based on the user's vision parameters, so that the display unit can display according to the display rules corresponding to the target partial pressure range and interact with the user. Since vision parameters vary from person to person, by incorporating the user's vision parameters to set specific display rules, the user's personalized experience is further enhanced.

[0151] In some embodiments, controlling the target door corresponding to the target pressure range to perform an opening and closing action includes: obtaining the current door opening and closing state; controlling the target door to perform a closing action when the current door opening and closing state is open; and controlling the target door to perform an opening action when the current door opening and closing state is closed.
