Abstract
Description
Technical Field
[0001] This application relates to the field of data acquisition technology, and in particular to a data acquisition device and a hand-worn device. Background Technology
[0002] Currently, one of the important methods for assessing human health status (such as heart function) is through the analysis and judgment of heart sound data. In clinical practice, doctors usually use traditional stethoscopes or electronic auscultation devices, placing the auscultation head in a specific area of the patient's chest to listen to the audio signals produced by the heart, and relying on their own clinical experience to determine whether the patient has any heart or systemic health abnormalities.
[0003] However, existing health monitors and environmental monitoring devices still have significant limitations. Most traditional devices are bulky and heavy, and their design is unsuitable for prolonged wear during exercise or daily activities. This often results in discomfort, restricted movement, and discontinuous data acquisition, making it impossible to achieve long-term, stable, and high-quality acquisition of weak physiological signals such as heart sounds during natural activities. Therefore, a new data acquisition device is urgently needed to collect data.

[0019] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0020] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.
[0021] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.
[0022] Currently, data collection is needed to assess health status. This data can include heart sound data, lung data, etc. Taking heart sound data collection as an example, doctors typically use stethoscopes or electronic auscultation devices to collect cardiac audio data, which they then use to assess the body's health based on experience. However, this data collection method has certain limitations. Most traditional devices are bulky and heavy, and their design is not suitable for prolonged wear during exercise or daily activities. This often leads to discomfort, limited movement, and discontinuous data collection, making it impossible to achieve long-term, stable, and high-quality collection of weak physiological signals such as heart sounds during natural activities. For example, the size or portability limitations of stethoscopes or electronic auscultation devices prevent the collection of data during special scenarios such as exercise, training, diet, and physical therapy.
[0023] Therefore, based on the shortcomings of the above data acquisition methods, this application proposes a data acquisition device. The design scheme of this application embodiment is as follows: data acquisition of the target area is achieved through a first data acquisition module and a second data acquisition module. Simultaneously, the entire device is housed within a wearable hand device, thus avoiding the problems of bulky and heavy devices with unsuitable structural designs for prolonged wear during sports or daily activities, which often result in discomfort, restricted movement, and discontinuous data acquisition. This data acquisition device, housed within a wearable hand device and utilizing two internal data acquisition modules, eliminates the need for specific large equipment for data acquisition. Data acquisition can be completed simply by wearing the device on the hand, enabling data collection based on a novel data acquisition device.
[0024] Based on this, embodiments of this application provide a data acquisition device, referring to... Figure 1 , Figure 1 This is a schematic diagram of the framework of the first embodiment of the data acquisition device of this application.
[0025] Reference Figure 1 This application provides a data acquisition device, which is installed within a hand-worn device 100. The data acquisition device includes: The first data acquisition module 10 is located at the first data acquisition position on the inner acquisition surface of the hand-wearing device 100 (generally a section in the middle of the palm or back of the hand when the hand-wearing device 100 is worn). The first data acquisition module 10 is used to acquire initial acquisition data of the target area 220. When the hand-wearing device is worn and the data acquisition device is acquiring data, the first data acquisition position is attached to the target area 220. The second data acquisition module 20 is located at the second data acquisition position on the outer acquisition surface of the hand-worn device 100. The second data acquisition module 20 is used to collect environmental noise data of the environmental area. The controller 30 is connected to the first data acquisition module 10 and the second data acquisition module 20. The controller 30 is used to perform noise filtering on the initial acquired data based on the environmental noise data to obtain the target acquired data.
[0026] In this embodiment, the data acquisition device is housed within the hand-worn device 100, enabling data acquisition through the hand-worn device 100. The acquired data can be heart sound data, lung data, or other data displaying bodily characteristics. This application uses heart sound data as an example. The hand-worn device 100 can be a smart ring, smart bracelet, smart bangle, or other hand-worn device, such as a smart chest patch. By housing the entire data acquisition device within the hand-worn device 100, data acquisition can be achieved using the hand-worn device 100, avoiding the size limitations of stethoscopes or electronic stethoscopes. This not only expands the application scenarios of data acquisition—allowing users to collect data at any time as needed and improving the accuracy of the final heart sound data by ensuring data diversity—but also expands the functionality of the hand-worn device 100. Furthermore, when using the hand-worn device 100 for data acquisition, by attaching the first data acquisition position to the target area 220, the first data acquisition module 10 can be used to acquire initial acquisition data from the target area 220 to complete the acquisition of heart sound data. The initial acquisition data is the data acquired from the target area 220. Simultaneously, the second data acquisition module 20 is used to acquire environmental noise data from the surrounding environment to complete the entire data acquisition process. The environmental noise data is the interference data of the environment in which the hand-worn device 100 is located. The acquired data from the target area 220 is then processed based on the environmental interference data to ensure the accuracy of the final target acquisition data, thereby ensuring the accuracy of the final detection of the target acquisition data. For example, the process of determining the target acquisition data from the initial acquisition data and environmental noise data can be to directly correct the initial acquisition data or filter out environmental noise based on the environmental noise data to obtain the target acquisition data. The data correction method can be a common noise filtering control algorithm, or other algorithms, which will not be described in detail here.
[0027] For example, refer to Figure 2 , Figure 2This is a schematic diagram illustrating the placement of the data acquisition device of this application. Taking a smart ring as an example, the hand-worn device 100 can be used. The first data acquisition module 10 can have three first acquisition sensors 11 on the smart ring, and the second data acquisition module 20 can have one second acquisition sensor 21 on the smart ring. The positions of the first and second acquisition sensors 11 and 21 can be along the central axis of the smart ring, or other arrangements are possible. For example, the inner acquisition surface generally refers to the inner side relative to the target area. If the user is accustomed to opening their palm for acquisition, the inner acquisition surface refers to the side of the smart ring on the palm. If the user is accustomed to clenching their fist for acquisition, the inner acquisition surface refers to the side of the smart ring on the back of the hand. The same principle applies to bracelets and wristbands. For example, the first data acquisition position of the first acquisition sensor 11 is required to be able to acquire heart sound data when the hand is placed against the heart, and not be obstructed by contact between fingers. The second data acquisition position of the second acquisition sensor 21 is required to be able to acquire environmental noise, and not be obstructed by contact between fingers, nor acquire heart sound data. Figure 2 The second data acquisition sensor 21 is actually positioned over a range. Among these ranges, Figure 2 The illustration shows that when the smart ring is worn, the first acquisition sensor 11 is located in the palm of the hand and the second acquisition sensor 21 is located in the back of the hand. This allows the heart sound to be collected when the user's palm is in contact with the heart (i.e., the target area 220). Of course, it can also be adaptively set according to the user's habits. For example, if the user is used to clenching their fist to check or the ring is worn on the thumb, the first acquisition sensor 11 can be worn in the back of the hand.
[0028] In this embodiment, a data acquisition device is provided, which is disposed within a wearable hand device. The device includes a first data acquisition module located at a first data acquisition position on the inner acquisition surface of the wearable hand device. This first data acquisition module is used to acquire initial data of a target area. When the wearable hand device is worn and the data acquisition device is acquiring data, the first data acquisition position is attached to the target area. A second data acquisition module is located at a second data acquisition position on the outer acquisition surface of the wearable hand device. This second data acquisition module is used to acquire environmental noise data of the environmental area. A controller is connected to the first and second data acquisition modules and is used to perform noise filtering on the initial acquired data based on the environmental noise data to obtain the target acquired data. This data acquisition device achieves data acquisition of the target area through the first and second data acquisition modules. Furthermore, the entire device is disposed within the wearable hand device, thus avoiding the problems of bulky and heavy devices with unsuitable structural designs for prolonged wear during exercise or daily activities, which often result in discomfort, restricted movement, and discontinuous data acquisition. This data acquisition device is installed inside a wearable hand device and uses two internal data acquisition modules to acquire data. This eliminates the need for specific large equipment and allows data acquisition to be completed while the device is worn on the hand. This new data acquisition device enables data collection.
[0029] Furthermore, based on the first embodiment of this application described above, a second embodiment of the data acquisition device of this application is proposed, wherein the first data acquisition module 10 includes: The first data acquisition unit is located in the middle area of the first data acquisition position. The first data acquisition unit is connected to the controller 30 and is used to acquire the first real-time data of the target area 220. Multiple second data acquisition units are symmetrically arranged on both sides of the central area. The second data acquisition units are connected to the controller 30 and are used to acquire second real-time data of the target area 220.
[0030] For example, the initial data acquisition includes data acquired by the first data acquisition unit and data acquired by multiple second data acquisition units. The first data acquisition unit and the multiple second data acquisition units can then be combined to acquire heart sound data. Alternatively, only one first data acquisition unit can be used for heart sound data acquisition. However, in this case, the user needs to wear the smart ring accurately so that the first data acquisition unit can acquire heart sound data accurately and efficiently. While the single data acquisition unit design can reduce the overall cost of the device, the accuracy of the acquired data cannot be guaranteed.
[0031] Furthermore, through the design of a first data pickup unit and multiple second data pickup units, multi-channel synchronous sampling and data fusion can be achieved, automatically selecting the optimal channel, and real-time detection of the signal energy of each sensor in contact with the skin. It automatically switches to the channel with the strongest vibration transmission, solving the problems of signal loss or reduction caused by unavoidable axial rotation due to wearing misalignment, and uneven fit. (See reference...) Figure 3 , Figure 3 This is another schematic diagram showing the placement of the data acquisition device in this application. Taking two second data pickup units as an example, four VPUs (Voice Pick-up Units) are placed inside the smart ring. One VPU, acting as the first data pickup unit, is placed at the 6 o'clock position on the fingertip (palm position). The other two VPUs, acting as second data pickup units, are symmetrically placed on either side of the first data pickup unit, with a spacing of 2mm to 5mm. The spacing is less than 5mm to avoid placing the second data pickup units in the gaps between the fingers, which would affect data acquisition. The spacing is greater than 2mm to allow for data acquisition using different data pickup units based on slight movements. Furthermore, Figure 3The smart ring's outer ring component includes the ring's outer ring parts, which are made of rigid material. The smart ring can be configured with either a localized noise reduction structure or a comprehensive noise reduction structure. This means that noise reduction can be applied to each data acquisition unit individually or the entire smart ring can be noise-reduced. Additionally, the correct wearing method of the ring will be indicated in the design of specific areas. For example, during the smart ring's data collection process, the two second data acquisition units collect heart sound data Y1 and Y2, respectively (second real-time data), while the first data acquisition unit collects Y3, i.e., first real-time data. The optimal heart sound data is then determined from Y3, Y1, and Y2. The optimal acquisition effect could be based on factors such as maximum vibration energy or maximum loudness. The data acquisition unit corresponding to the optimal acquisition effect is then designated as the target data acquisition unit. Simultaneously, correction values are determined based on heart sound data other than the target data acquisition unit to correct the heart sound data of the target data acquisition unit, ensuring the accuracy of the final determined heart sound data. For example, if Y3 is the heart sound data of the target data acquisition unit, Y1 and Y2 will determine a correction value Y4. Then, Y3 is corrected based on Y4 to obtain the final environmental noise data. Finally, the target acquisition data is determined based on the environmental noise data and the initial acquisition data. The entire process of Y1 and Y2 determining a correction value Y4, and then correcting Y3 based on Y4 to obtain the final environmental noise data, can predefine corresponding correction rules. For example, a certain proportion of the sum of Y1 and Y2 can be used as the correction value Y4. Then, Y1 is modified using the correction value Y4 in the form of vibration or loudness correction. Of course, other correction methods can also be used, which will not be elaborated here. Combining at least three data acquisition units for fusion processing can ensure the accuracy of the final initial acquisition data and is applicable to scenarios with slight movements or changes in pressure on the smart ring. Alternatively, more second data acquisition units can be included, and the correction value can be determined based on these second data acquisition units, or the smallest heart sound data can be deleted based on more second data acquisition units, and then the correction value can be determined based on the remaining heart sound data.
[0032] Furthermore, referring to Figure 4 , Figure 4 This is a schematic diagram of a noise reduction enclosure structure in the data acquisition device of this application. Both the first data acquisition unit and the second data acquisition unit include a first acquisition sensor 11 and a noise reduction enclosure structure sealing the first acquisition sensor. The first acquisition sensor 11 is connected to the controller 30. The noise reduction enclosure structure includes: The first silicone component A1 is attached to the sensing surface of the first acquisition sensor 11; The second silicone component is attached to the side and bottom surface of the first acquisition sensor 11 and forms a mounting groove B1 with the first silicone component A1. The mounting groove B1 is used to install the first acquisition sensor 11.
[0033] In this embodiment, each data acquisition unit includes a first acquisition sensor 11 and a noise-reducing enclosure structure that seals the first acquisition sensor. The first acquisition sensor 11 is connected to the controller 30 to transmit and process the acquired heart sound data. The first acquisition sensor 11 or the second acquisition sensor 21 in the data acquisition unit can be a bone conduction sensor, a bone voiceprint sensor, or other data acquisition sensors, which are not limited here. Furthermore, the noise-reducing enclosure structure mainly uses materials such as silicone to reduce noise along the heart sound transmission path of the first acquisition sensor 11. The design of the noise-reducing enclosure structure can be a first silicone component A1 attached to the sensing surface of the first acquisition sensor 11, and a second silicone component forming a mounting groove B1 with the first silicone component A1. That is, the first silicone component A1 and the second silicone component ultimately form a mounting groove B1 to install the first acquisition sensor 11 within the mounting groove B1, thereby achieving noise reduction and enclosure of the first acquisition sensor 11. Of course, the first silicone component A1 and the second silicone component can also form an area for fixing the first acquisition sensor 11 in the mounting groove B1, so that the first acquisition sensor 11 can be fixed in the mounting groove B1. For example, the mounting groove B1 is exactly the size of the first acquisition sensor 11, thereby avoiding vibration or movement of the first acquisition sensor 11 during use, so as to ensure the accuracy of the data collected by the first acquisition sensor 11.
[0034] Exemplarily, the first silicone component A1 primarily transmits data, transmitting heart sound vibrations to the sensing surface of the first acquisition sensor 11. Its thickness can be 0.2-0.5 mm, and it is made of soft silicone material with a Shore A rating of 30-40. The second silicone component covers the sides, bottom, and edges of each first acquisition sensor 11, thus forming a mounting groove B1 with the first silicone component A1. The side thickness of the second silicone component can be 0.5-1.0 mm, also made of soft silicone material with a Shore A rating of 30-40. In this case, the mounting groove B1 ensures that the first acquisition sensor 11 does not make hard contact with the ring-shaped shell of the smart ring or the finger bones, thus isolating structural noise transmission. Exemplarily, refer to... Figure 4 The first acquisition sensor 11 is located inside the second silicone component (on the side opposite to the first silicone component A1, i.e. the side that is in contact with the sensing surface of the first acquisition sensor 11), and the first acquisition sensor 11 is fixed by the elastic clamping force of the second silicone component.
[0035] In another embodiment, reference is made to Figure 5 , Figure 5This is another schematic diagram of the noise reduction enclosure structure in the data acquisition device of this application. Both the first data acquisition unit and the second data acquisition unit include a first acquisition sensor 11 and a noise reduction enclosure structure sealing the first acquisition sensor. The first acquisition sensor 11 is connected to the controller 30. The noise reduction enclosure structure includes: The first silicone component A1 is attached to the sensing surface of the first acquisition sensor 11; The second silicone component is attached to the side and bottom surface of the first acquisition sensor 11. Metal shell A4 is disposed between the first silicone component A2 and the second silicone component, and the metal shell A4 is used to form an installation groove B1 with the second silicone component.
[0036] In this embodiment, the noise reduction enclosure structure also includes a metal shell A4, which allows the metal shell A4 to form a mounting groove B1 with the second silicone assembly to mount the first data acquisition sensor 11. The thickness of the metal shell A4 is less than or equal to 0.30 mm, thus protecting the first data acquisition sensor 11 from damage due to impact, meaning that the sensor within the mounting groove B1 will not be directly damaged by an impact, while minimizing the influence of the metal on data acquisition.
[0037] Furthermore, the bottom silicone component A3 in the second silicone component is a hollow structure B2, and the bottom silicone component A3 is the silicone component in the second silicone component that is attached to the bottom surface of the first acquisition sensor 11.
[0038] For example, the bottom silicone component A3 in the second silicone component is a hollow structure B2. The design thickness of the bottom silicone component A3 can be 0.5 to 0.8 mm, and the silicone hardness is 30 to 45 Shore A (soft but not deformable). The hollow structure B2 and the choice of material can reduce vibration transmission, thereby ensuring the accuracy of the entire data acquisition.
[0039] Furthermore, referring to Figure 6 , Figure 6 This is a schematic diagram of a sensor connection in the power control system of this application. The first data acquisition module 10 also includes: A flexible circuit board 13 is provided, on which a first acquisition sensor 11 is mounted and disposed adjacent to the bottom surface of the first acquisition sensor 11. The flexible circuit board 13 is used to fix the first acquisition sensor 11 in the mounting groove B1. The two adjacent first acquisition sensors 11 are connected by a flexible circuit board 13, and the flexible circuit board 13 is designed in a bent shape.
[0040] For example, two adjacent first acquisition sensors 11 or a first acquisition sensor 11 and a second acquisition sensor 21 are connected by an FPC (Flexible Printed Circuit). The flexible FPC is designed in a bent shape to reduce strain interference between the acquisition sensors. The bent shape can be S-shaped, V-shaped, or other non-linear shapes. On the other hand, a fixing area can be provided inside the mounting groove B1, and the first acquisition sensor 11 can be fixed in the mounting groove B1 based on the flexible circuit board 13, for example, directly as... Figure 6 This embedded fixing method ensures the stability of the first acquisition sensor 11, thereby improving the lifespan and accuracy of the entire data acquisition device. For example, user shaking during running will not affect the final acquired data.
[0041] In another embodiment, reference is made to Figure 7 , Figure 7 This is a schematic diagram of a data acquisition device in a hand-wearing device according to the present application. The sensing surfaces of the first acquisition sensors 11 are all configured to meet the first condition, and the spacing between adjacent first acquisition sensors 11 meets a preset spacing threshold. The first condition is that the sensing surface is perpendicular to a radius of the hand-wearing device.
[0042] In this embodiment, the sensing surfaces of the first acquisition sensors 11 are all configured to meet the first condition, and the spacing between adjacent first acquisition sensors 11 meets a preset spacing threshold, i.e., referring to... Figure 7 Multiple first acquisition sensors 11 are spaced apart to ensure data acquisition accuracy by maintaining a spacing of 5mm ≥ X1 = X2 ≥ 2mm. This ensures that minor changes to the smart ring will not affect normal data acquisition. This spacing is typically designed for the ring; other devices can adjust the spacing based on their specific needs. Simultaneously, the placement angle of the first acquisition sensor 11 must be X3 = 90 degrees (meaning the sensing surface of the first acquisition sensor 11 is perpendicular to a radius of the wearable device). Figure 7 Another interpretation is that the tangent point of the wearable device should be a tangent line, with at least one tangent line parallel to the sensing surface. This ensures maximum contact surface fit when the smart ring shifts, guaranteeing effective data acquisition. Of course, the second acquisition sensor 21 in the second data acquisition module 20 can be on the same axis as the first acquisition sensor 11 in the first data pickup unit. The placement angle of the second acquisition sensor 21 should be 95 degrees ≥ x 4 ≥ 85 degrees to maximize the use of the internal space of the smart ring. Of course, the second acquisition sensor 21 in the second data acquisition module 20 can also adopt other settings, which will not be described in detail here. Further details can be found in [reference needed]. Figure 8 , Figure 8This is a schematic diagram of a wearable hand device according to this application. The outer surface of the first silicone component A1 is flush with or slightly convex (0.1-0.3 mm) to the skin-contacting surface of the inner ring of the annular shell. Figure 8 When the first silicone component A1 protrudes by 0.1-0.3mm, the entire acquisition surface can better contact the target area 220, so as to ensure that the heart sound vibration is transmitted to the first acquisition sensor 11 without loss through the silicone layer, thereby ensuring the accuracy of heart sound acquisition.
[0043] Specifically, the entire data acquisition device employs a noise-reducing enclosed structure, utilizing flexible materials and bending designs between the sensors to achieve zero hard contact between the sensors and the rigid shell or finger bones. The high damping properties of silicone isolate structurally transmitted noise, improving the signal-to-noise ratio of heart sound acquisition by 5-15dB, thus solving the technical pain point of significant noise interference during sensor acquisition. Furthermore, by precisely positioning 2-4 sensors in a uniformly distributed ring, at least one signal is strongly coupled regardless of the angle at which the device is placed on the chest, preventing acquisition failures due to misalignment and improving the consistency and stability of the multi-module array, thereby enhancing acquisition quality. Additionally, the silicone material is soft, medical-grade silicone, and the hard points of the modules are completely covered by the silicone layer, providing a comfortable feel. The silicone pad thickness is only 0.7-1.4mm, suitable for smart rings with a thickness of ≤3mm, without altering the ring's miniaturized form.
[0044] Furthermore, based on the first and second embodiments of this application described above, a third embodiment of the data acquisition device of this application is proposed, wherein the second data acquisition module 20 includes: The third data acquisition unit is located at the second data acquisition position. The second acquisition sensor 21 in the third data acquisition unit is connected to the controller 30. The second acquisition sensor 21 is used to acquire environmental noise data of the environmental area.
[0045] For example, the second data acquisition module 20 includes a third data acquisition unit, which acquires environmental noise data of the environmental area, i.e., noise in the environment. This environmental noise data can then be used to filter out airborne environmental noise. Through adaptive filtering, environmental vibration (environmental noise data) interference is subtracted from the fingertip-side signal, significantly improving the signal-to-noise ratio. Of course, multiple third data acquisition units can exist and be evenly distributed at the second data acquisition location. The average noise level can be determined based on multiple units to ensure the accuracy of noise filtering. It is worth noting that the internal configuration of the third data acquisition unit is the same as that of the first and second data acquisition units, differing only in its location; therefore, it will not be described again here.
[0046] Furthermore, the data acquisition device also includes: The sealing connection unit 40 is disposed between two adjacent acquisition sensors and forms a sealed cavity for the flexible circuit board through the noise reduction sealing structure on the acquisition sensor.
[0047] In this embodiment, the data acquisition device also includes a sealing connection unit 40. The sealing connection unit 40 can be a silicone connection. By placing the sealing connection unit 40 between two adjacent acquisition sensors, a sealed cavity is formed inside the smart ring based on the noise reduction and sealing structure of the acquisition sensors and the inner wall of the annular housing, achieving IPX7 or higher waterproof and dustproof functions for the device. In other words, all components of the entire data acquisition device are housed within a large sealed cavity, thereby ensuring the effectiveness of the entire data acquisition device and reducing the impact of the external environment on the data acquisition device. Further details can be found in... Figure 8 The diagram presents a front view of a smart ring. The smart ring can be a recessed metal structure with three protruding silicone pads at the locations of the three primary data acquisition sensors to ensure accurate data collection. Alternatively, it can be flush with the sealing connection unit 40. Furthermore, a data acquisition device is housed within the entire recessed metal structure; that is, the entire circle of the smart ring is encased in silicone pads for the data acquisition device. Alternatively, it can be a semi-circular recessed structure, with the data acquisition device housed within this semi-circular recess, specifically protecting the first and second data acquisition sensors with only half a circle of silicone pads. Of course, the smart ring can also have other structures, as long as they allow for the installation of the data acquisition device; these will not be elaborated upon here.
[0048] It should be noted that the above examples are only for understanding this application and do not constitute a limitation on the internal control logic of the data acquisition device of this application. Any simple modifications based on this technical concept are within the protection scope of this application.
[0049] This application provides a hand-wearing device, which includes the aforementioned data acquisition device.
[0050] It's worth noting that the wearable device can be a ring, bracelet, or wristband, or any other wearable device that allows direct contact with the target area; these will not be detailed here. The entire wearable device collects data from the target area through a first data acquisition module and a second data acquisition module. The entire device is housed within the wearable device, thus avoiding the problems of bulky, heavy devices with unsuitable designs for prolonged wear during exercise or daily activities, which often result in discomfort, restricted movement, and discontinuous data collection. This data acquisition device, housed within the wearable device and utilizing two internal data acquisition modules, eliminates the need for specialized large equipment. Data collection can be completed simply by wearing it on the hand, representing a novel data acquisition method.
[0051] This application provides a hand-wearing device, which includes: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to execute the control logic inside the controller in the first embodiment described above, that is, the logic of controlling the switches inside the controller, which means that the controller can be implemented using software algorithms.
