Technical Field

[0001] The present invention relates to the technical field of wireless charging, and particularly to a wireless charging method and system for an intelligent ring. Background Art

[0002] As a new type of wearable device, the intelligent ring is favored by more and more consumers for its small size, portability and diverse functions. The intelligent ring integrates various functions such as health monitoring, sports tracking, information reminder, etc. The capacity of its built-in small battery is limited, and it needs to be charged frequently to maintain the normal operation of the device.

[0003] However, the traditional charging method for intelligent rings mostly uses wired charging, which charges the intelligent ring by connecting it to a charging cable and a power adapter. This method has many drawbacks. On the one hand, the connection process of the charging cable is cumbersome. For the small-sized intelligent ring, frequent plugging and unplugging of the charging interface is likely to cause damage to the interface, affecting the service life of the device and unable to better protect the corresponding charging process of the intelligent ring. On the other hand, the wired charging method limits the user's activity range, thus reducing the convenience of use. Summary of the Invention

[0007] Step S2: Obtain the remaining battery power and the battery charging duration of the intelligent ring, and perform induction adjustment charging processing on the intelligent ring based on the remaining battery power and the battery charging duration of the intelligent ring and in combination with the charging induction range turns, to generate an induction adjustment charging process for the intelligent ring;

[0008] Step S3: Obtain the corresponding battery charging progress through the induction adjustment charging process of the intelligent ring, and control the charging mode of the intelligent ring based on the battery charging progress.

[0022] Step S233: Analyze and determine the corresponding number of turns of the charging induction contact coil according to the size of the charging induction area corresponding to the smart ring under the current battery conditions, and based on the number of turns of the charging induction contact coil and in combination with the charging induction range turns, perform induction adjustment charging on the convex hull corresponding to the smart ring to generate the smart ring induction adjustment charging process.

[0023] Further, the charging induction area calculation formula described in step S232 is specifically:

[0024]

[0025] In the formula, A is the size of the charging induction area corresponding to the smart ring under the current battery conditions, T s is the remaining charging duration of the battery corresponding to the smart ring, t is the time variable parameter, M(t) is the external wireless charging magnetic field reception ability coefficient corresponding to time t, P c is the output power of the wireless charging transmitter in the wireless charging base, D is the distance between the smart ring and the wireless charging transmitter, η is the wireless charging influence efficiency, E b (t) is the remaining battery power of the smart ring corresponding to time t, E max is the maximum battery storage capacity of the smart ring, and ζ is the correction coefficient of the charging induction area size.

[0026] Further, the specific process of the induction adjustment charging process described in step S233 is to adaptively adjust and control the number of turns of the coil in contact with the smart ring to be the number of turns of the charging induction contact coil by using the double-ended turn pieces corresponding to the charging induction range turns, and accurately align the charging space groove between the wireless charging base and the charging induction range turns with the convex hull corresponding to the smart ring to execute the corresponding smart ring charging process.

[0027] Further, step S3 includes the following steps:

[0028] Step S31: Obtain the battery charging progress of the smart ring on the wireless charging base through the smart ring induction adjustment charging process;

[0029] Step S32: Control the charging mode of the smart ring based on the battery charging progress. If the charging power corresponding to the battery charging progress is close to full, then use the wireless charging base to execute the corresponding trickle charging working mode to reduce the corresponding energy loss during the charging process;

[0030] Step S33: If the charging power corresponding to the battery charging progress is not close to full charge, obtain the battery characteristics of the smart ring, and perform battery safety analysis on the smart ring based on the battery characteristics of the smart ring to obtain the battery charging safety range corresponding to the smart ring;

[0031] Step S34: Based on the battery charging safety range and combined with the wireless charging base, use the pulse charging technology to execute the corresponding fast charging working mode, so as to increase the waveform peak values of the charging voltage and charging current within the battery charging safety range to improve the corresponding charging speed.

[0032] Further, step S4 includes the following steps:

[0034] Step S42: Perform timing synchronization processing on the charging voltage, charging current and charging temperature to obtain the corresponding charging voltage, charging current and charging temperature within the same timing range;

[0035] Step S43: Perform statistical analysis on the fluctuation changes of the charging voltage, charging current and charging temperature within the same timing range to obtain the charging parameter fluctuation change rate, including the voltage fluctuation change rate, current fluctuation change rate and temperature fluctuation change rate;

[0038] Further, step S45 includes the following steps:

[0039] Based on the ring charging energy conversion efficiency, perform parameter safety threshold calculation on the corresponding voltage fluctuation change rate, current fluctuation change rate or temperature fluctuation change rate to obtain the charging parameter change safety threshold corresponding to the smart ring, including the charging voltage change safety threshold, charging current change safety threshold and charging temperature change safety threshold;

[0040] Based on the safety threshold of the charging parameter change corresponding to the smart ring, perform safety judgment on the charging voltage, charging current or charging temperature. If the charging voltage, charging current or charging temperature is less than the corresponding safety threshold of the charging parameter change, continue to perform the safety judgment; if the charging voltage, charging current or charging temperature is greater than or equal to the corresponding safety threshold of the charging parameter change, use the wireless charging circuit to perform wireless charging protection control on the corresponding smart ring during the induction adjustment charging process of the smart ring, so as to automatically cut off the corresponding wireless charging circuit when there is overvoltage, overcurrent or abnormal temperature during the charging process, generate a wireless charging protection control strategy for the smart ring, and execute the corresponding wireless charging protection work for the smart ring.

[0041] Furthermore, the present invention also provides a wireless charging system for a smart ring, which is used to execute the wireless charging method for the smart ring as described above. The wireless charging system for the smart ring includes:

[0042] A wireless charging position correction module, which is used to design a circular induction coil inside the smart ring, and use the wireless charging base and the charging induction housing to sense the relative position and relative angle of the smart ring in real time; based on the relative position and relative angle of the smart ring, use the ring insulation protection layer to creep and transfer the smart ring to the correct wireless charging position;

[0043] An induction turn number adjustment charging module, which is used to obtain the remaining battery power and the battery charging duration to be charged corresponding to the smart ring, and perform induction adjustment charging processing on the smart ring based on the remaining battery power and the battery charging duration to be charged corresponding to the smart ring and in combination with the charging induction range turn number, so as to generate an induction adjustment charging process for the smart ring;

If the charging power corresponding to the battery charging progress is close to full charge, use the wireless charging base to execute the corresponding trickle charging working mode; if the charging power corresponding to the battery charging progress is not close to full charge, use the wireless charging base to execute the corresponding fast charging working mode;

[0045] A wireless charging protection module, which is used to obtain the corresponding charging voltage, charging current and charging temperature through the induction adjustment charging process of the smart ring, and perform wireless charging protection control on the corresponding smart ring during the induction adjustment charging process of the smart ring by using the wireless charging circuit, generate a wireless charging protection control strategy for the smart ring, and execute the corresponding wireless charging protection work for the smart ring.

[0046] The beneficial effects of the present invention:

[0047] 1. Compared with the prior art, the beneficial effect of the wireless charging method of the intelligent ring proposed by the present invention is that by designing a circular induction coil inside the intelligent ring, it can ensure that the ring can achieve good docking with the induction area of the wireless charging base. The combination of the wireless charging base and the charging induction housing enables the relative position and angle of the intelligent ring to be accurately sensed. This induction technology avoids the cumbersome operation of precise alignment required by the user every time they charge, automatically adjusts the ring to the optimal charging position, greatly improving the convenience and accuracy of charging. Through the mechanism of the intelligent ring's peristaltic transfer, even if the user accidentally places the ring in a position that is not completely aligned, the induction technology can automatically adjust the position of the ring to reach the optimal charging position. This not only effectively avoids the efficiency loss caused by position deviation during charging but also reduces the charging instability phenomenon caused by poor contact over a long time, thereby extending the battery life and enhancing the user experience. The insulating protective layer of the ring can avoid potential risks of overheating or poor current conduction while ensuring the normal operation and charging of the device, further improving the safety of the device. Secondly, by obtaining the remaining battery power and the remaining charging time of the intelligent ring, the charging of the ring can be more precisely adjusted and optimized. The key to this step is to be able to monitor the battery status in real time and adjust the charging method accordingly. By combining the number of turns in the charging induction range, it can help accurately judge the charging induction area required by the battery, thus avoiding waste and inefficiency in traditional charging methods. This step can also dynamically adjust the number of turns of the induction coil in contact with the charging according to different situations to achieve the optimal battery management effect, extend the service life of the intelligent ring battery and ensure its stability, thereby enhancing the convenience and user experience. Then, by sensing and adjusting the charging process and obtaining the battery charging progress in real time, the charging mode can be dynamically controlled. When the battery is close to full, it will switch to the trickle charging working mode to avoid overcharging. This can not only effectively reduce battery damage but also extend the battery life. When the battery charging progress is low, it will automatically switch to the fast charging mode to accelerate the charging process to meet the user's need to quickly resume using the device. This flexible charging mode control mechanism fully considers the battery protection needs and the user's demand for charging speed, providing a safe and efficient charging experience. Compared with traditional charging methods, this intelligent charging management significantly improves the charging accuracy and effect, avoiding unnecessary energy waste or insufficient charging situations, thus greatly improving the charging efficiency.Finally, by monitoring the charging voltage, current, and temperature in real time, this step can significantly enhance the safety and stability during wireless charging. As a highly integrated small electronic product, the smart ring may have problems such as overheating, unstable current, or voltage fluctuations during charging, which often lead to device overheating, low charging efficiency, and even potential battery damage. Through precise monitoring of the charging voltage, current, and temperature, real-time adjustments can be made to ensure that these charging parameters always remain within a safe range. Specifically, when the voltage or current is too high, the charging power will be reduced in a timely manner to avoid overcharging; when the temperature is too high, the charging speed will be automatically reduced, or a cooling mechanism will be activated to protect the device from overheating. The precise adjustment of the wireless charging circuit can effectively prevent device damage caused by poor power adaptation, ensuring the stability and safety of the smart ring during charging, thus better protecting the corresponding charging process of the smart ring and providing users with a safe, stable, and efficient charging experience.

[0048] 2. The wireless charging system of the smart ring proposed by the present invention is generally composed of a wireless charging position correction module, an inductive turn adjustment charging module, a wireless charging mode control module, and a wireless charging protection module. It can implement the wireless charging method of any smart ring described in the present invention, and is used to jointly realize the wireless charging method of the smart ring through the operations between computer programs running on each module. The internal structure of the system cooperates with each other, which can greatly reduce repetitive work and manpower input, and can quickly and effectively provide a more accurate and efficient wireless charging process for the smart ring, thus simplifying the operation process of the wireless charging system of the smart ring.

[0057] To achieve the above object, please refer to Figures 1 to 4 , the present invention provides a wireless charging method for a smart ring, and the method includes the following steps:

[0058] Step S1: Design a ring-shaped induction coil inside the smart ring, and use the wireless charging base and the charging induction housing to sense the relative position and relative angle of the smart ring in real time; based on the relative position and relative angle of the smart ring, use the ring insulation protection layer to creep and transfer the smart ring to the correct wireless charging position;

[0059] Step S2: Obtain the remaining battery power and the battery charging duration of the smart ring, and perform induction adjustment charging processing on the smart ring based on the remaining battery power and the battery charging duration of the smart ring and in combination with the charging induction range turns, to generate a smart ring induction adjustment charging process;

[0060] Step S3: Obtain the corresponding battery charging progress through the intelligent ring's induction adjustment of the charging process, and control the charging mode of the intelligent ring based on the battery charging progress. If the charging power corresponding to the battery charging progress is close to full charge, then use the wireless charging base to execute the corresponding trickle charging working mode; if the charging power corresponding to the battery charging progress is not close to full charge, then use the wireless charging base to execute the corresponding fast charging working mode;

[0061] Step S4: Obtain the corresponding charging voltage, charging current, and charging temperature through the intelligent ring's induction adjustment of the charging process, and use the wireless charging circuit to perform wireless charging protection control on the intelligent ring corresponding to the intelligent ring's induction adjustment of the charging process based on the charging voltage, charging current, and charging temperature, generate an intelligent ring wireless charging protection control strategy, and execute the corresponding intelligent ring wireless charging protection work.

[0062] In the embodiment of the present invention, please refer to Figure 1 As shown in the figure, it is a schematic diagram of the step flow of the power operation and maintenance method of the present invention serving a virtual power plant. In this example, the power operation and maintenance method serving a virtual power plant includes the following steps:

[0063] Step S1: Design a ring-shaped induction coil inside the intelligent ring, and use the wireless charging base and the charging induction housing to sense the relative position and relative angle of the intelligent ring in real time; based on the relative position and relative angle of the intelligent ring, use the ring insulation protection layer to creep and transfer the intelligent ring to the correct wireless charging position;

[0064] In the embodiment of the present invention, by designing a circular induction coil inside the intelligent ring and combining the wireless charging base and the charging induction housing corresponding to the wireless charger (as Figure 4 shown), a set of electromagnetic induction systems is constructed. Through this system, the intelligent ring and the wireless charging base can sense the relative position and angle information of each other in real time. When the intelligent ring approaches the wireless charging base, the induction coil will generate an electromagnetic field signal according to the changes in the angle and position of the ring relative to the base, and feedback it to the charging base. The wireless charging base judges the accurate position of the intelligent ring based on this information, and through the mechanical or electromagnetic adjustment device set on the corresponding insulation protection layer of the base, makes the intelligent ring creep to the wireless charging area. During this process, the insulation protection layer of the intelligent ring serves as a medium for transmitting force, ensuring that the corresponding convex hull on the intelligent ring is correctly positioned in the charging groove on the wireless charging base, so that it can effectively dock with the charging area without direct contact.

[0065] Step S2: Obtain the remaining battery power and the remaining charging duration of the smart ring, and perform induction adjustment charging on the smart ring based on the remaining battery power and the remaining charging duration of the smart ring and in combination with the charging induction range turns, generating a smart ring induction adjustment charging process;

[0066] In an embodiment of the present invention, a battery management unit is provided inside the smart ring. This unit is responsible for real-time monitoring of the remaining battery power and its remaining charging duration. Through a wireless communication protocol, the smart ring transmits information such as the remaining battery power and the remaining charging duration to the charging induction range turns. The charging induction range turns perform intelligent adjustment based on this information and in combination with the number of turns in its induction range (i.e., the number of turns of the induction coil and the charging power), so as to adjust the power output and current change during the charging process, and adaptively adjust and control the number of turns of the coil in contact with the smart ring by the corresponding double-ended turn pieces in the charging induction range turns to be the charging induction contact coil turns to execute the corresponding smart ring charging process, and finally generate a smart ring induction adjustment charging process.

[0067] Step S3: Obtain the corresponding battery charging progress through the smart ring induction adjustment charging process, and perform charging mode control on the smart ring based on the battery charging progress. If the charging power corresponding to the battery charging progress is close to full charge, then use the wireless charging base to execute the corresponding trickle charging working mode; if the charging power corresponding to the battery charging progress is not close to full charge, then use the wireless charging base to execute the corresponding fast charging working mode;

[0068] In an embodiment of the present invention, during the wireless charging process of the smart ring, the base real-time monitors the charging progress of the battery and judges its state according to the charging power of the battery. When the battery charging progress is close to full charge, the wireless charging base will automatically switch to the trickle charging mode. At this time, the charging current gradually decreases, ensuring a more stable charging process and avoiding overcharging to damage the battery. When the battery is not close to full charge, the base will maintain a relatively high charging power according to the charging progress and enter the fast charging mode to minimize the charging time. The charging progress of the smart ring is fed back through the voltage and current changes during the induction adjustment process, and the base dynamically adjusts the charging mode according to these changes.

[0069] Step S4: Obtain the corresponding charging voltage, charging current, and charging temperature through the smart ring induction adjustment charging process, and perform wireless charging protection control on the smart ring corresponding to the smart ring induction adjustment charging process based on the charging voltage, charging current, and charging temperature, generating a smart ring wireless charging protection control strategy to execute the corresponding smart ring wireless charging protection work.

[0070] In an embodiment of the present invention, during the charging process of the smart ring, the charging base acquires and monitors the charging voltage, current, and charging temperature in real time. When it is detected that the charging voltage exceeds the set range, the wireless charging circuit of the base will automatically adjust the current output to prevent battery damage caused by excessive voltage. If the charging current is too large, the base will also adjust in a timely manner to ensure that the battery is charged within a safe range. In addition, when the temperature rises to the set threshold during the charging process, the base will activate the overheat protection mechanism, which may reduce the charging current or suspend charging to lower the temperature and avoid damage to the smart ring and its battery caused by high temperature. The charging protection control strategy will be dynamically adjusted according to real-time data to ensure that the smart ring is always in a safe and optimal charging state during the charging process and can automatically disconnect the corresponding wireless charging circuit in case of overvoltage, overcurrent, or overheating, and finally perform the corresponding wireless charging protection work for the smart ring.

[0071] Further, step S1 includes the following steps:

[0072] Step S11: By winding a small induction coil around the corresponding circumference inside the smart ring to generate a ring-shaped induction coil;

[0073] Step S12: Use the wireless charging base to sense the relative position of the placed smart ring in real time;

[0074] Step S13: Use the charging induction housing to sense the relative angle between the placed smart ring and the wireless charging base in real time;

[0075] Step S14: Make a layout judgment based on the relative position and relative angle of the smart ring. If the relative position is correctly located on the charging space of the wireless charging base and the relative angle is 0°, it is considered that the smart ring has reached the correct wireless charging position; if the relative position deviates from the charging space of the wireless charging base or the relative angle is not 0°, the smart ring is wriggled and transferred to the correct wireless charging position using the ring insulation protection layer.

[0076] As an embodiment of the present invention, refer to Figure 2 shown in Figure 1 is the detailed step flow schematic diagram of step S1 in

[0077] Step S11: By winding a small induction coil around the corresponding circumference inside the smart ring to generate a ring-shaped induction coil;

[0078] In an embodiment of the present invention, a small induction coil is designed around the circumference of the inside of a smart ring. This coil adopts efficient wireless energy transmission technology and ensures a maximized electromagnetic induction area through a ring-shaped layout. The size and shape of the induction coil are precisely calculated to adapt to the specific size of the ring and to be compatible with a wireless charging base. The design of the induction coil requires efficient power transmission over a short distance while ensuring that the circuit inside the ring can operate stably. The design uses advanced magnetic field guidance technology to quickly and accurately transfer power to the battery of the smart ring, ultimately generating a ring-shaped induction coil.

[0079] Step S12: using the wireless charging base to sense the relative position of the placed smart ring in real time;

[0080] In the embodiment of the present invention, a plurality of sensing elements are provided in the wireless charging base, which can sense the position of the smart ring in real time. When the ring is placed on the wireless charging base, the sensing system in the base will actively detect the relative position of the smart ring. The sensing elements in the base will determine whether the smart ring is located in the exact position of the charging space based on the changes in its electromagnetic field. If the ring is in the charging space, its precise position will be transmitted to the control system in real time to ensure the accuracy and efficiency of power transmission, and finally obtain the corresponding relative position of the smart ring.

[0081] Step S13: using the charging induction housing to sense in real time the corresponding relative angle between the placed smart ring and the wireless charging base;

[0082] In an embodiment of the present invention, a charging induction shell is also provided above the wireless charging base, and the shell has built-in angle sensing elements. These elements can sense the relative angle between the smart ring and the base in real time. The angle sensing system adopts a high-precision tilt sensor, which can measure the precise angle between the ring and the surface of the base. Through the combination of electromagnetic field signals and angle sensing elements, the relative angle changes of the ring can be fed back in real time. If the ring deviates from the correct angle of the charging base, it will automatically adjust to ensure that the ring can be wirelessly charged in the correct position, and finally the corresponding relative angle between the smart ring and the wireless charging base is obtained.

[0083] Step S14: Layout judgment is performed based on the relative position and relative angle corresponding to the smart ring. If the relative position is exactly located on the charging space corresponding to the wireless charging base and the relative angle is 0°, it is considered that the smart ring has reached the correct wireless charging position; if the relative position deviates from the charging space corresponding to the wireless charging base or the relative angle is not 0°, the insulating protective layer of the ring is used to move the smart ring to the correct wireless charging position.

[0084] In an embodiment of the present invention, by combining the relative position and angle data obtained from previous inductive monitoring, the charging state of the smart ring is judged. When the relative position of the smart ring is correct and the angle is 0°, it is confirmed that the ring has been accurately placed in the charging area of the wireless charging base, and charging will start. When the relative position deviates from the charging space or the relative angle is not 0°, the insulating protective layer of the smart ring is controlled to achieve the peristaltic movement of the ring, so as to promote the slight rotation or sliding of the smart ring, and realize the precise alignment of the corresponding convex hull in the smart ring with the charging space groove between the wireless charging base and the charging induction range turns, ensuring its accurate docking with the charging base. In this process, the design of the insulating protective layer can effectively prevent direct contact with the battery or other electrical parts, avoid any potential short - circuit or damage risks, and ensure the safe and stable transfer of the device to the correct position for wireless charging. Once the ring moves to the correct position, the system will automatically identify and start the charging process.

[0085] Further, step S2 includes the following steps:

[0086] Step S21: Obtain the remaining battery power of the smart ring;

[0087] Step S22: Obtain the corresponding battery charge to be charged based on the remaining battery power of the smart ring, and predict the charging duration to be charged for the corresponding smart ring on the wireless charging base according to the battery charge to be charged, so as to obtain the charging duration to be charged for the battery of the smart ring;

[0088] Step S23: Based on the remaining battery power of the smart ring and the charging duration to be charged, and in combination with the charging induction range turns, perform induction - adjusted charging processing on the smart ring to generate an induction - adjusted charging process for the smart ring.

[0089] As an embodiment of the present invention, referring to Figure 3 shown, it is Figure 1 a detailed step - flow schematic diagram of step S2 in

[0090] Step S21: Obtain the remaining battery power of the smart ring;

[0091] In the embodiment of the present invention, the battery power monitoring module built in the smart ring monitors the battery power level in real time. Through the battery power detection sensor, the remaining battery power data is obtained. This process is implemented by the battery management system. The battery management system will output the remaining battery power in the form of a percentage. The processing chip on the smart ring will regularly obtain the battery power information. And if the power is lower than the set threshold, it will prompt the user that the battery power is insufficient through the display screen or other output methods. The remaining battery power data can be transmitted to an external device (such as a smart phone or a wireless charging base) through the built-in wireless communication module (such as Bluetooth or Wi-Fi) for subsequent charging decisions, and finally the remaining battery power corresponding to the smart ring is obtained.

[0092] Step S22: Obtain the corresponding battery charge to be replenished based on the remaining battery power of the smart ring, and predict the charging duration to be replenished for the corresponding smart ring on the wireless charging base according to the battery charge to be replenished, so as to obtain the battery charging duration to be replenished corresponding to the smart ring;

[0093] In the embodiment of the present invention, the remaining battery power is obtained through the battery power detection module, and the battery charge to be replenished is calculated. The battery charge to be replenished is the power difference required to charge from the current power state to 100%. Using the battery charging characteristics and charging curve, combined with the remaining power and battery capacity, the time required for the battery of the smart ring to charge from the current remaining power to full charge is calculated. Then, after the wireless charging base receives the battery charge to be replenished data, according to factors such as battery charging efficiency, charging power, and temperature during charging, a preset charging time prediction model is used to calculate the charging duration to be replenished. This prediction process is carried out by the charging control module in the wireless charging base, and a specific charging duration estimate is generated according to the charging characteristics of the smart ring battery and the current environmental conditions. This information can be fed back to the user in real time, or the estimated charging duration can be displayed through the base display screen, and finally the battery charging duration to be replenished corresponding to the smart ring is obtained.

[0094] Step S23: Based on the remaining battery power and the battery charging duration to be replenished corresponding to the smart ring, and combined with the charging induction range turns, perform induction adjustment charging processing on the smart ring to generate the smart ring induction adjustment charging process.

[0095] In an embodiment of the present invention, by obtaining the remaining power of the smart ring and the data of the remaining charging duration, and comprehensively analyzing in combination with the induction range turns of the wireless charging base of the smart ring (i.e., the size and sensitivity of the induction area of the charging base), according to the prediction of the charging duration, the charging base adjusts the magnetic field strength and frequency through its electromagnetic induction module to achieve efficient and precise charging regulation. When the smart ring enters the induction range of the charging base, the charging base starts to automatically identify and adjust its electromagnetic induction position to ensure that the wireless charging process is always stable. According to the prediction of the remaining battery power and the charging duration, the intensity of the induction area and the charging strategy will be dynamically optimized to ensure that the charging rate of the battery matches the actual demand, avoiding overcharging or slow charging. During the charging process, the processing chip of the smart ring and the charging base will continuously feedback the charging status through wireless communication, adjust the power output and current change during the charging process, adaptively adjust and control the number of turns of the coil in contact with the smart ring as the charging induction contact coil turns through the corresponding double-ended turn pieces within the charging induction range turns, and accurately align the convex hull corresponding to the smart ring with the charging space groove between the wireless charging base and the charging induction range turns to execute the corresponding smart ring charging process, ensuring that the battery of the smart ring is fully charged within a reasonable time and maintaining the battery health, and finally generating the smart ring induction adjustment charging process.

[0096] Further, step S23 includes the following steps:

[0097] Step S231: Obtain the corresponding external wireless charging magnetic field reception ability coefficient through the smart ring corresponding to the wireless charging base;

[0098] In an embodiment of the present invention, the corresponding external wireless charging magnetic field reception ability coefficient is obtained through the smart ring corresponding to the wireless charging base. Specifically, when implemented, the wireless charging base is built with an induction module and will exchange data with the charging reception module on the smart ring through wireless signals. First, when the smart ring comes into contact with the charging base, electromagnetic induction will occur between the smart ring and the induction coil of the base. At this time, the wireless charging base detects the distance, output power, and corresponding influencing efficiency during the wireless charging process between the ring and the built-in charging transmitter through a group of sensors. After processing these information, the external wireless charging magnetic field reception ability coefficient of the smart ring is obtained. The coefficient reflects the effective degree of the ring receiving the charging magnetic field and the charging efficiency. The coefficient is dynamically adjusted by the electromagnetic reception system of the charging base according to the physical characteristics of the ring and the received magnetic field strength to ensure the maximization of the charging efficiency in different environments, and finally the external wireless charging magnetic field reception ability coefficient is obtained.

[0099] Step S232: Based on the external wireless charging magnetic field reception ability coefficient, the remaining battery power of the smart ring, and the battery charging duration, use the charging induction area calculation formula to calculate the charging induction area of the smart ring, and obtain the size of the charging induction area corresponding to the smart ring under the current battery conditions;

[0100] In the embodiment of the present invention, by combining the external wireless charging magnetic field reception ability coefficient, the remaining battery power of the smart ring, the battery charging duration, the output power of the wireless charging transmitter, the distance between the smart ring and the wireless charging transmitter, the wireless charging influence efficiency, the maximum battery storage capacity of the smart ring, and related parameters, a suitable charging induction area calculation formula is formed for quantitative calculation to determine the required charging induction area under the current battery state. The calculation formula is adjusted according to the relationship between the remaining battery power and the charging duration to ensure that the obtained charging induction area meets the battery charging requirements, so as to better change the corresponding number of turns of the charging coil during the charging process. Finally, the size of the charging induction area corresponding to the smart ring under the current battery conditions is obtained. In addition, the charging induction area calculation formula can also use any charging induction technology in the field to replace the process of charging induction area calculation, and is not limited to the charging induction area calculation formula.

[0101] Step S233: Analyze and determine the corresponding number of turns of the charging induction contact coil according to the size of the charging induction area corresponding to the smart ring under the current battery conditions, and based on the number of turns of the charging induction contact coil and in combination with the charging induction range turns, perform induction adjustment charging on the convex hull corresponding to the smart ring to generate the smart ring induction adjustment charging process.

[0102] In the embodiment of the present invention, by analyzing and determining the number of turns of the charging induction contact coil corresponding to the intelligent ring according to the size of the charging induction area under the current battery condition, and based on the number of turns of the charging induction contact coil and in combination with the charging induction range turns, the intelligent ring is subjected to induction adjustment charging processing. Specifically, when the charging induction area of the intelligent ring is calculated, the most suitable number of turns of the charging induction contact coil is determined according to this area. The charging induction range turns on the wireless charging base adapt to the charging requirements of the intelligent ring by automatically adjusting their number of turns to ensure the maximum transmission efficiency of electromagnetic energy. When the number of turns of the charging induction contact coil is determined, the wireless charging base will dynamically adjust the working mode of the coil according to the set charging induction range turns, and control the electromagnetic field distribution of the coil through the double-end turn pieces, that is, control the corresponding number of turns of the charging induction contact coil through the turn pieces, so that the number of turns of the contact coil between the intelligent ring and the charging base is accurately matched, and the charging space groove between the wireless charging base and the charging induction range turns is accurately aligned with the corresponding convex hull of the intelligent ring. This process is adjusted through an adaptive algorithm to ensure the efficient and stable transmission of electric energy during the charging process. During the induction adjustment charging process, the current and voltage are monitored and adjusted in real time to maintain the safety and charging efficiency of battery charging, and finally the induction adjustment charging process of the intelligent ring is generated.

[0103] Further, the specific formula for calculating the charging induction area described in step S232 is as follows:

[0104]

[0105] In the formula, A is the size of the charging induction area corresponding to the intelligent ring under the current battery condition, T s is the remaining charging time of the battery corresponding to the intelligent ring, t is the time variable parameter, M(t) is the external wireless charging magnetic field reception ability coefficient corresponding to time t, P c is the output power of the wireless charging transmitter in the wireless charging base, D is the distance between the intelligent ring and the wireless charging transmitter, η is the wireless charging influence efficiency, E b (t) is the remaining battery power of the intelligent ring corresponding to time t, E max is the maximum battery storage capacity corresponding to the intelligent ring, and ζ is the correction coefficient of the charging induction area size.

[0106] The present invention obtains a charging induction area calculation formula through the use of a specific mathematical model and verification, which is used to calculate the charging induction area of the intelligent ring. This formula fully considers the size A of the charging induction area corresponding to the intelligent ring under the current battery condition, the remaining charging time T of the battery corresponding to the intelligent ring s , the time variable parameter t, the external wireless charging magnetic field reception ability coefficient M(t) corresponding to time t, and the output power P of the wireless charging transmitter in the wireless charging basec , the distance D between the smart ring and the wireless charging transmitter, the wireless charging influence efficiency η, and the remaining battery power E of the smart ring corresponding to time t b (t), the maximum battery storage capacity E of the smart ring max , the correction coefficient ζ of the charging induction area size, where the output power P corresponding to the wireless charging transmitter in the wireless charging base c , the distance D between the smart ring and the wireless charging transmitter, the wireless charging influence efficiency η, and the time variable parameter t constitute a functional relationship of an external wireless charging magnetic field reception ability coefficient M(t) corresponding to time t According to the mutual correlation relationship between the charging induction area size A of the smart ring under the current battery condition and the above parameters, a functional relationship is formed:

[0107]

[0108] This formula can realize the calculation process of the charging induction area of the smart ring. At the same time, by introducing the correction coefficient ζ of the charging induction area size, it can be adjusted according to the error situation in the calculation process, thereby improving the accuracy and applicability of the charging induction area calculation formula.

[0109] Furthermore, the specific process of the induction adjustment charging process described in step S233 is to use the double-ended turn pieces corresponding to the charging induction range turn to adaptively adjust and control the number of turns of the coil in contact with the smart ring to be the charging induction contact coil turns, and through the charging space groove between the wireless charging base and the charging induction range turn and the convex hull corresponding to the smart ring for precise alignment to execute the corresponding smart ring charging process.

[0110] Furthermore, step S3 includes the following steps:

[0111] Step S31: Obtain the battery charging progress of the smart ring corresponding to the wireless charging base through the smart ring induction adjustment charging process;

[0112] In the embodiment of the present invention, during the wireless charging process, first, data related to the battery charging progress of the wireless charging base is obtained through the sensor on the smart ring. Specifically, the battery management system embedded in the smart ring can detect the charging status of the current battery, such as battery power, temperature, health status, etc. These information are connected to the wireless charging base through wireless signals. The sensors in the smart ring regularly monitor the change of the battery power and update the battery charging progress in real time. The charging progress data is transmitted through the receiving module of the base to ensure the effective tracking and control of the charging process, provide accurate charging progress feedback, and finally obtain the battery charging progress of the smart ring.

[0113] Step S32: Control the charging mode of the smart ring based on the battery charging progress. If the charging power corresponding to the battery charging progress is close to full charge, use the wireless charging base to execute the corresponding trickle charging working mode to reduce the corresponding energy loss during charging;

[0114] In the embodiment of the present invention, based on the obtained battery charging progress data, when the battery of the smart ring is close to full charge, it will automatically enter the trickle charging mode to reduce energy loss. The trickle charging mode is realized through the wireless charging base. The wireless charging base is embedded with a battery management control unit, which judges the charging state according to the battery power progress. If the battery charging is close to 100%, the charging voltage will be automatically reduced to a constant value, and the current will also gradually decrease, avoiding overcharging and reducing heat generation. The intelligent control module in the wireless charging base ensures the efficient transfer of energy in this charging mode, avoids overheating of the battery, thereby prolonging the battery life and minimizing energy loss, and finally executes the corresponding trickle charging working mode.

[0115] Step S33: If the charging power corresponding to the battery charging progress is not close to full charge, obtain the battery characteristics of the smart ring, and perform battery safety analysis on the smart ring based on the battery characteristics of the smart ring to obtain the battery charging safety range corresponding to the smart ring;

[0116] In the embodiment of the present invention, if it is determined that the charging progress is not close to full charge, the battery characteristics of the smart ring will be further analyzed. This process first obtains battery characteristic parameters such as voltage, current, temperature, and internal resistance of the battery through the battery monitoring system built in the smart ring. Then, a specific battery model will be used for safety analysis to evaluate the charging stability and safety of the current battery at different charging powers. This analysis is based on the built-in algorithm, which automatically calculates the safe voltage and current range of battery charging, so as to judge whether it is suitable to continue to accelerate charging or adjust the charging strategy. The analysis result can provide a decision basis for subsequent charging mode adjustment, ensuring that there will be no safety risks such as battery damage or short circuit caused by overvoltage or overcurrent during charging, and finally obtaining the battery charging safety range corresponding to the smart ring.

[0117] Step S34: Based on the battery charging safety range and combined with the wireless charging base, use pulse charging technology to execute the corresponding fast charging working mode to increase the waveform peak values of the charging voltage and charging current within the battery charging safety range to improve the corresponding charging speed.

[0118] In an embodiment of the present invention, according to the battery safety analysis result, if the battery charging progress permits and the battery characteristics are within the safe range, the smart ring will use pulse charging technology for fast charging through a wireless charging base. During this process, the control module of the wireless charging base will adjust the voltage and current waveforms, using periodic pulse signals instead of a constant current to ensure that the battery temperature during charging remains within the safe range. The pulse charging technology improves the charging rate through short-time high-voltage and high-current pulses instead of continuous high current, and achieves the heat dissipation effect by adding heat dissipation blocks inside the wireless charging base. This can avoid overheating caused by long-term high-current charging and effectively shorten the charging time. In this charging mode, the intelligent control unit of the wireless charging base will continuously monitor the battery power, temperature, and other charging-related parameters to ensure that the fast charging does not exceed the safe charging range of the battery. Finally, the charging voltage and the waveform peak value corresponding to the charging current are increased within the battery charging safety range to improve the corresponding charging speed.

[0119] Further, step S4 includes the following steps:

[0120] Step S41: Obtain the corresponding charging voltage, charging current, and charging temperature through the induction adjustment of the charging process by the smart ring;

[0121] In an embodiment of the present invention, during the wireless charging process, first, the integrated sensor system of the smart ring senses the current charging state, and the sensors are used to monitor the real-time data of voltage, current, and temperature during charging. Specifically, the smart ring is built-in with multiple sensors, including a voltage sensor, a current sensor, and a temperature sensor. Data during the charging process is obtained through these sensors. The voltage sensor can measure the output voltage of the charging circuit, the current sensor measures the magnitude of the charging current, and the temperature sensor monitors the temperature changes of the ring and during the charging process in real time. When these data are sensed, the data will be transmitted to an external device through the wireless communication module for analysis and processing, and finally, the corresponding charging voltage, charging current, and charging temperature are obtained.

[0122] Step S42: Perform timing synchronization processing on the charging voltage, charging current, and charging temperature to obtain the corresponding charging voltage, charging current, and charging temperature within the same timing range;

[0123] In the embodiment of the present invention, after obtaining the real-time data of the charging voltage, charging current, and charging temperature, the time series synchronization processing technology is used to process these data. First, the real-time data of the charging voltage, current, and temperature each have different acquisition time points. In order to compare and analyze these data, a time series synchronization algorithm is used to align the time of each item of data to ensure that they have the same time reference within the same time window. This synchronization processing enables the data collected by different sensors to be analyzed and compared within the same time range, ensuring the time series consistency of each data point, and finally obtaining the corresponding charging voltage, charging current, and charging temperature within the same time series range.

[0124] Step S43: Perform statistical analysis on the fluctuations of the corresponding charging voltage, charging current, and charging temperature within the same time series range to obtain the charging parameter fluctuation rate, including the voltage fluctuation rate, current fluctuation rate, and temperature fluctuation rate.

[0125] In the embodiment of the present invention, after performing time series synchronization on the charging voltage, current, and temperature data, further statistical analysis of the fluctuations is carried out. By calculating the fluctuation rate, the fluctuation degree of each charging parameter can be quantified. First, the mean and standard deviation of the synchronized voltage, current, and temperature are calculated to evaluate the fluctuation range of each parameter. The voltage fluctuation rate is obtained by calculating the relative percentage of the voltage change; the current fluctuation rate is evaluated by the fluctuation degree of the current; the temperature fluctuation rate is quantified by the amplitude of the temperature change. Through these data of the fluctuation rate, the stability and fluctuation conditions during the charging process can be reflected, and finally the charging parameter fluctuation rate is obtained, including the voltage fluctuation rate, current fluctuation rate, and temperature fluctuation rate.

[0126] Step S44: Evaluate the energy conversion of the corresponding smart ring during the inductive regulated charging process of the smart ring to obtain the ring charging energy conversion efficiency.

[0127] In the embodiment of the present invention, by using the evaluation method of the charging energy conversion efficiency, the energy conversion efficiency of the smart ring is evaluated. First, by calculating the relationship between the energy input and output of the smart ring during wireless charging, the conversion efficiency of the built-in charging system of the smart ring is evaluated, that is, the ratio of the corresponding energy input and output of the wireless charger, so as to determine the energy loss situation under different working conditions, and finally the ring charging energy conversion efficiency is obtained.

[0128] Step S45: Based on the ring charging energy conversion efficiency and the charging parameter fluctuation rate, use the wireless charging circuit to perform wireless charging protection control on the corresponding smart ring during the inductive regulated charging process of the smart ring, generate a smart ring wireless charging protection control strategy, and execute the corresponding smart ring wireless charging protection work.

[0129] In an embodiment of the present invention, based on the charging energy conversion efficiency and the charging parameter fluctuation change rate, a wireless charging circuit is used to protect and control the smart ring. First, by designing a charging protection control algorithm, according to the previous evaluation results, a charging protection threshold is set. For example, if the charging voltage, current or temperature fluctuation exceeds the set threshold, or the charging energy conversion efficiency is too low, the wireless charging circuit will activate a protection mechanism. This mechanism avoids overheating or instability during the charging process by dynamically adjusting the voltage and current output and controlling the temperature, thereby protecting the smart ring from damage. The wireless charging circuit monitors the charging status in real time and responds to abnormal situations during the charging process to ensure charging safety. The generated wireless charging protection control strategy plays a role in regulating and protecting throughout the charging process, ensuring that the smart ring can be efficiently charged while avoiding any potential damage, ensuring that the corresponding wireless charging circuit can be automatically disconnected in case of overvoltage, overcurrent or overheating, and finally performing the corresponding wireless charging protection work for the smart ring.

[0130] Further, step S45 includes the following steps:

[0131] Based on the ring charging energy conversion efficiency, parameter safety thresholds are calculated for the corresponding voltage fluctuation change rate, current fluctuation change rate or temperature fluctuation change rate to obtain the charging parameter change safety thresholds corresponding to the smart ring, including the charging voltage change safety threshold, the charging current change safety threshold and the charging temperature change safety threshold;

[0132] In an embodiment of the present invention, by obtaining multiple key parameters during the battery charging process of the smart ring, including charging voltage, charging current, and charging temperature, the changes of these parameters are crucial for the charging efficiency and safety of the battery. Based on the battery technology of the ring, first, the voltage volatility, current volatility, and temperature volatility during the charging process are measured to evaluate the safe operating range. For each key parameter, a mathematical model between voltage, current, temperature, and charging efficiency during the charging process is established through test data. This model can determine through historical data analysis that the fluctuation values of voltage, current, and temperature under different charging states will not cause overheating or battery damage. Through statistical analysis of the changes in voltage, current, and temperature, and combined with the previously quantified energy conversion efficiency of the ring charging, a reasonable change threshold is calculated, that is, the safety threshold is equal to the product of the fluctuation change rate corresponding to each parameter and the energy conversion efficiency of the ring charging. These values represent the safe fluctuation range of these parameters during the charging process. When the fluctuations of charging voltage, current, or temperature exceed this safety threshold, a warning mechanism will be triggered and corresponding safety measures will be taken. After calculation, a set of safety thresholds are obtained, and these thresholds will be applied to the real-time monitoring and control of the charging process, and finally, the safety thresholds of the charging parameter changes corresponding to the smart ring are obtained, including the safety threshold of the charging voltage change, the safety threshold of the charging current change, and the safety threshold of the charging temperature change.

[0133] Preferably, based on the safety thresholds of the charging parameter changes corresponding to the smart ring, a safety judgment is made on the charging voltage, charging current, or charging temperature. If the charging voltage, charging current, or charging temperature is less than the corresponding safety threshold of the charging parameter change, the safety judgment is continued; if the charging voltage, charging current, or charging temperature is greater than or equal to the corresponding safety threshold of the charging parameter change, the wireless charging circuit is used to perform wireless charging protection control on the corresponding smart ring during the charging process, so as to automatically cut off the corresponding wireless charging circuit when there is too high voltage, too large current, or abnormal temperature during the charging process, generate a wireless charging protection control strategy for the smart ring, and perform the corresponding wireless charging protection work for the smart ring.

[0134] In the embodiment of the present invention, by monitoring parameters such as charging voltage, current, and temperature in real time, and comparing and judging these parameters according to the previously calculated safety thresholds. During specific operations, the charging system will obtain the voltage, current, and temperature data of the current charging state in real time through sensors. These real-time data are compared with the preset safety thresholds for changes in charging parameters to determine whether there are any abnormalities. If the real-time voltage, current, or temperature is less than the corresponding safety threshold, it indicates that the charging process is within the safe range, and then the normal wireless charging operation will continue without any adjustment. If it is detected that the charging voltage, current, or temperature exceeds the safety threshold, the protection control function of the wireless charging circuit will be immediately triggered. The control chip in the wireless charging circuit will automatically adjust the charging process according to the preset protection logic, and take measures such as reducing the charging voltage, reducing the charging current, or disconnecting the charging to prevent the device from overheating or being damaged. In addition, it can also generate corresponding intelligent ring wireless charging protection control strategies in real time, and adjust the parameters during the charging process through this strategy. For example, when the temperature is too high, the current output will be automatically reduced, or when the voltage is too high, the wireless charging circuit will be disconnected to avoid damaging the battery of the intelligent ring. In this way, the intelligent ring can be automatically protected during the charging process to ensure the safety and stability during the charging process, and finally execute the corresponding intelligent ring wireless charging protection work.
