Description

Technical Field

[0001] The present invention relates to the technical field of wireless charging technology, and in particular to a method and device for managing wireless charging of earphones, an electronic device, and a storage medium. Background Art

[0002] With the continuous popularization of wireless charging technology, portable electronic devices such as earphones increasingly adopt wireless charging methods to provide a more convenient charging experience. However, due to the working principle of wireless charging involving the energy transmission of high-frequency electromagnetic fields, certain heat is generated during the charging process. Especially in small devices, the heat dissipation space and efficiency are relatively limited, which is likely to cause the device temperature to be too high. Summary of the Invention

[0003] To ensure the safety and stability of the device during wireless charging, the present application provides a method and device for managing wireless charging of earphones, an electronic device, and a storage medium.

[0004] The first invention object of the present application is achieved through the following technical solutions:

[0005] A method for managing wireless charging of earphones, the method for managing wireless charging of earphones includes:

[0006] Obtain the wireless charging start information of the mobile power supply;

[0007] According to the wireless charging start information, determine whether there is a mobile device on the wireless charging coil of the mobile power supply. If there is a mobile device on the wireless charging coil, generate device connection information;

[0008] Confirm the device type through the device information database for the device connection information to obtain device type information. If the device type information is an earphone, generate earphone charging mode information;

[0009] Charge the earphone according to the earphone charging mode information, and during the charging process, the system continuously obtains the earphone temperature information;

[0010] Compare the temperature information collected inside the earphone with a preset earphone temperature threshold. If the earphone temperature information exceeds the preset earphone temperature threshold, the wireless charging function of the earphone is turned off, and processing earphone temperature information is generated. If the earphone temperature information is lower than the preset earphone temperature threshold, the wireless charging function is turned on, and continue charging information is generated.

[0011] By adopting the above technical solution, when the earphone is charging, the internal temperature sensor monitors the temperature in real time and compares it with the preset earphone temperature threshold. When the temperature exceeds the threshold, the earphone can actively turn off the wireless charging function to avoid further temperature rise caused by continuous charging, thus effectively preventing potential safety hazards and device damage caused by overheating. When the earphone temperature returns to the preset safe threshold range, the wireless charging function automatically restarts and generates information to continue charging, ensuring that the earphone charging process can quickly resume after cooling. This dynamic adjustment mechanism shortens the non-charging time of the earphone and improves the charging efficiency while ensuring safety. The wireless charging transmitter indirectly senses the charging state of the earphone through the earphone's feedback behavior (such as turning off or on the wireless charging function). The transmitter does not need to directly obtain internal data such as the temperature, voltage, and current of the earphone, thus avoiding the need for additional expansion of the communication protocol and enhancing the compatibility and adaptability of the wireless charging transmitter to different devices. The earphone autonomously completes the monitoring, judgment, and control of the temperature, and the transmitter only needs to respond to the feedback signal of the earphone. Such a design transfers the complex temperature control logic to the earphone side and reduces the design complexity of the wireless charging transmitter. By dynamically adjusting the charging state, it avoids the impact of continuous charging of the earphone at high temperature on the battery life, and at the same time accurately controls the charging time and power output according to the real-time temperature state of the earphone, extending the service life of the earphone battery. During the period when the earphone turns off the wireless charging function, the transmitter automatically enters the low-power standby mode, which not only avoids ineffective energy transmission but also reduces overheating or unnecessary power consumption of the transmitter caused by abnormal load.

[0012] In a preferred example of this application, it can be further configured that: according to the wireless charging start information, it is judged whether there is a mobile device on the wireless charging coil of the mobile power supply. If there is a mobile device on the wireless charging coil, device connection information is generated, and it further includes:

[0013] If there is no mobile device on the wireless charging coil, mobile power supply shutdown information is generated.

[0014] By adopting the above technical solution, it can effectively avoid power waste caused by no device on the wireless charging coil. When the wireless charging coil does not detect a mobile device, mobile power supply shutdown information is generated in a timely manner, triggering the mobile power supply to enter the low-power standby or fully off state, thereby reducing the energy consumption of the mobile power supply and extending the power endurance time.

[0015] In a preferred example of this application, it can be further configured that: the device type confirmation of the device connection information is performed through the device information database to obtain device type information. If the device type information is an earphone, earphone charging mode information is generated, including:

[0016] Obtain the device power requirement information and the device communication characteristic information from the device connection information;

[0017] If the device power requirement information conforms to the headset power requirement standard in the device information database and the device communication characteristic information conforms to the headset communication protocol type in the device information database, then confirm the type of the device and generate the device type information;

[0018] If the device type information is a headset, then generate the headset charging mode information.

[0019] By adopting the above technical solution, by extracting the device power requirement information and the communication characteristic information from the device connection information, and performing matching analysis with the headset power requirement standard and the communication protocol type in the device information database, it is ensured that the judgment of the device type is accurate, thus avoiding problems such as charging mismatch or function abnormality caused by misidentification. If it is confirmed that the device is a headset, further generate the adapted headset charging mode information, including the charging power range, the communication protocol adaptation rule, and the temperature control strategy, to meet the personalized charging needs of the headset.

[0020] In a preferred example of the present application, it can be further configured as: If the device power requirement information conforms to the headset power requirement standard in the device information database and the device communication characteristic information conforms to the headset communication protocol type in the device information database, then confirm the type of the device and generate the device type information, and further include:

[0021] If the device power requirement information does not conform to the headset power requirement standard in the device information database and / or the device communication characteristic information does not conform to the headset communication protocol type in the device information database, then confirm that the mobile device is a non-headset device;

[0022] If the mobile device is the non-headset device, then generate the normal charging mode information.

[0023] By adopting the above technical solution, through the comparison of the device power requirement information with the headset power requirement standard, and the matching analysis of the device communication characteristic information with the headset communication protocol type, it can accurately judge whether the device is a headset. If the device does not conform to the relevant standards of the headset, it is promptly confirmed as a non-headset device, and the adapted normal charging mode information is generated, thus avoiding the charging abnormality problem caused by misidentification. The generated normal charging mode information dynamically adjusts the output power and the charging rule according to the power requirement and the communication protocol characteristics of the non-headset device, ensuring the charging stability and safety of the non-headset device.

[0024] In a preferred example of the present application, it can be further configured as: The processing of the headset temperature information includes:

[0025] According to the processed earphone temperature information, calculate the current power output value through the set temperature control algorithm based on the battery power, temperature and power demand of the earphone, and use the current power output value as the wireless charging output power;

[0026] If the earphone temperature information returns to the preset earphone temperature threshold, generate earphone temperature recovery information, and according to the earphone temperature recovery information, restore the wireless charging output power to the preset normal charging power.

[0027] By adopting the above technical solution, through dynamic calculation based on the battery power, temperature and power demand of the earphone, generate the current power output value and use it as the output power of wireless charging, avoiding continuous charging at a fixed power in a high-temperature state, which may cause the temperature to rise further, thus effectively protecting the internal battery and other key components of the earphone. The set temperature control algorithm can analyze the actual state of the earphone in real time. After the earphone temperature returns to the preset safety threshold, by generating earphone temperature recovery information, automatically restore the normal charging power output, ensuring the continuity and efficiency of the charging process, and at the same time avoiding unnecessary losses caused by frequent charging interruptions. In a high-temperature state, by adjusting the output power to reduce the heat accumulation inside the earphone, shorten the time for the earphone to recover from high temperature, effectively reduce the interference of high temperature on the charging process, and improve the overall charging efficiency. By dynamically adjusting the power output, avoid battery damage caused by excessively high or low charging power, keep the battery charging within a safe power range, thus extending the battery life and reducing the risk of battery capacity attenuation caused by high temperature. Through the independent operation of the temperature control algorithm at the earphone end, transfer the complex temperature control logic and real-time detection to the earphone end. The transmitter only needs to adjust the output power according to the feedback of the earphone, without directly processing the temperature, voltage and current data of the earphone. This design reduces the processing burden of the transmitter and improves the compatibility of the system with different earphone devices.

[0028] In a preferred example of the present application, it can be further configured as follows: when the earphone temperature information returns to the preset earphone temperature threshold, generate earphone temperature recovery information, and according to the earphone temperature recovery information, restore the wireless charging output power to the preset normal charging power, and further include:

[0029] If the earphone is removed from the wireless charging coil during the cooling process, generate earphone removal from coil information;

[0030] According to the earphone removal from coil information, pause the wireless charging output power.

[0031] By adopting the above technical solutions, it is possible to effectively detect whether the earphone is removed from the wireless charging coil during the earphone cooling process, and timely generate earphone removal coil information to trigger the operation of pausing the wireless charging output power. This mechanism avoids the ineffective power output of continuing to supply power when the earphone is not in the normal charging position, prevents the waste of electric energy, and at the same time reduces the additional burden on the transmitting end hardware. In addition, by generating earphone removal coil information and pausing the power output, it is possible to effectively avoid problems such as overheating and overloading of the earphone caused by incorrect placement, improving the safety and efficiency of wireless charging.

[0032] In a preferred example of the present application, it can be further configured as follows: The earphone wireless charging management method further includes:

[0033] Obtain the battery voltage information and battery current information of the earphone;

[0034] Judge whether there is a charging abnormality in the battery voltage information and the battery current information through a preset charging status detection model. If there is an abnormality in the battery voltage information and the battery current information, generate charging protection measure information.

[0035] By adopting the above technical solutions, by obtaining the battery voltage information and battery current information of the earphone and combining with a preset charging status detection model, it is possible to accurately judge whether there is an abnormality during the charging process, such as overvoltage or overcurrent abnormal conditions. Once an abnormality is detected, timely generate charging protection measure information and implement operations such as reducing the power output and pausing the charging, thereby effectively avoiding possible equipment damage or safety hazards during the charging process.

[0036] The second above-mentioned invention object of the present application is achieved through the following technical solutions:

[0037] An earphone wireless charging management device, the earphone wireless charging management device includes:

[0038] A wireless charging start information acquisition module, used to acquire the wireless charging start information of the mobile power supply;

[0039] A device connection detection and confirmation module, used to judge whether there is a mobile device on the wireless charging coil of the mobile power supply according to the wireless charging start information. If there is the mobile device on the wireless charging coil, generate device connection information;

[0040] A device type identification and charging mode generation module, used to confirm the device type through a device information database for the device connection information to obtain device type information. If the device type information is an earphone, generate earphone charging mode information;

[0041] The earphone charging and temperature monitoring module is used to charge the earphone according to the earphone charging mode information, and during the charging process, the system can obtain the earphone temperature information in real time;

[0042] The temperature threshold comparison and charging status management module is used to compare the temperature information collected inside the earphone with a preset earphone temperature threshold. If the earphone temperature information exceeds the preset earphone temperature threshold, the wireless charging function of the earphone will be turned off, and processed earphone temperature information will be generated. If the earphone temperature information is lower than the preset earphone temperature threshold, the wireless charging function will be turned on, and continue charging information will be generated.

[0043] By adopting the above technical solutions, during the charging process of the earphone, the temperature is monitored in real time through an internal temperature sensor and compared with a preset earphone temperature threshold. When the temperature exceeds the threshold, the earphone can actively turn off the wireless charging function to avoid further temperature increase caused by continuous charging, thus effectively preventing potential safety hazards and equipment damage caused by overheating. When the earphone temperature returns to the preset safe threshold range, the wireless charging function is automatically restarted and continue charging information is generated, ensuring that the earphone charging process can quickly resume after cooling. This dynamic adjustment mechanism shortens the non-charging time of the earphone, improves the charging efficiency while ensuring safety. The wireless charging transmitter indirectly senses the charging status of the earphone through the feedback behavior of the earphone (such as turning off or on the wireless charging function). The transmitter does not need to directly obtain internal data such as the temperature, voltage, and current of the earphone, thus avoiding the need for additional extension of the communication protocol and enhancing the compatibility and adaptation ability of the wireless charging transmitter to different devices. The earphone autonomously completes the monitoring, judgment, and control of the temperature inside. The transmitter only needs to respond to the feedback signal of the earphone. Such a design transfers the complex temperature control logic to the earphone side, reducing the design complexity of the wireless charging transmitter. By dynamically adjusting the charging status, it avoids the influence of continuous charging at high temperature on the battery life of the earphone. At the same time, according to the real-time temperature status of the earphone, the charging time and power output are accurately controlled, extending the service life of the earphone battery. During the period when the earphone turns off the wireless charging function, the transmitter automatically enters the low-power standby mode, which not only avoids ineffective energy transmission but also reduces the overheating or unnecessary power consumption of the transmitter caused by abnormal load.

[0044] The above object three of the present application is achieved through the following technical solutions:

[0045] An electronic device includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, the steps of the above earphone wireless charging management method are implemented.

[0046] The above object four of the present application is achieved through the following technical solutions:

[0047] A computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the steps of the above-mentioned wireless charging management method for the earphone are implemented.

[0048] In summary, the present application includes at least one of the following beneficial technical effects:

[0049] 1. When the earphone is charging, the internal temperature sensor monitors the temperature in real time and compares it with the preset earphone temperature threshold. When the temperature exceeds the threshold, the earphone can actively turn off the wireless charging function to avoid further temperature rise caused by continuous charging, thereby effectively preventing safety hazards and equipment damage caused by overheating. When the earphone temperature returns to the preset safe threshold range, the wireless charging function automatically restarts and generates information to continue charging, ensuring that the earphone charging process can quickly resume after cooling. This dynamic adjustment mechanism shortens the non-charging time of the earphone and improves the charging efficiency while ensuring safety. The wireless charging transmitter indirectly senses the charging state of the earphone through the feedback behavior of the earphone (such as turning off or on the wireless charging function), and the transmitter does not need to directly obtain internal data such as the temperature, voltage, and current of the earphone, thus avoiding the need for additional extension of the communication protocol and improving the compatibility and adaptation ability of the wireless charging transmitter to different devices. The earphone autonomously completes the monitoring, judgment, and control of the temperature, and the transmitter only needs to respond to the feedback signal of the earphone. Such a design transfers the complex temperature control logic to the earphone side and reduces the design complexity of the wireless charging transmitter. By dynamically adjusting the charging state, it avoids the influence of continuous charging at high temperature on the battery life of the earphone, and at the same time accurately controls the charging time and power output according to the real-time temperature state of the earphone, extending the service life of the earphone battery. During the period when the earphone turns off the wireless charging function, the transmitter automatically enters the low-power standby mode, which not only avoids ineffective energy transmission but also reduces the overheating or unnecessary power consumption of the transmitter caused by abnormal load;

[0050] 2. By dynamically calculating based on the battery power, temperature, and power requirements of the earphone, a current power output value is generated and used as the output power of wireless charging, avoiding further temperature increase caused by continuous charging at a fixed power in a high-temperature state, thereby effectively protecting the internal battery and other key components of the earphone. The set temperature control algorithm can analyze the actual state of the earphone in real time. After the earphone temperature returns to the preset safety threshold, by generating earphone temperature recovery information, the normal charging power output is automatically restored, ensuring the continuity and efficiency of the charging process, while avoiding unnecessary losses caused by frequent charging interruptions. In a high-temperature state, by adjusting the output power to reduce the heat accumulation inside the earphone, the time for the earphone to recover from high temperature is shortened, effectively reducing the interference of high temperature on the charging process and improving the overall charging efficiency. By dynamically adjusting the power output, battery loss caused by too high or too low charging power is avoided, the battery is charged within a safe power range, thereby extending the battery life and reducing the risk of battery capacity attenuation caused by high temperature. Through the independent operation of the temperature control algorithm at the earphone end, complex temperature control logic and real-time detection are transferred to the earphone end. The transmitting end only needs to adjust the output power according to the feedback of the earphone, without directly processing the temperature, voltage, and current data of the earphone. This design reduces the processing burden of the transmitting end and improves the compatibility of the system with different earphone devices;

[0051] 3. It can effectively detect whether the earphone is removed from the wireless charging coil during the earphone cooling process and generate earphone removal coil information in a timely manner, triggering the operation of pausing the wireless charging output power. This mechanism avoids the ineffective power output of continuing to supply power when the earphone is not in the normal charging position, prevents power waste, and reduces the additional burden on the hardware of the transmitting end. In addition, by generating earphone removal coil information and pausing the power output, problems such as overheating and overloading of the earphone caused by incorrect placement can be effectively avoided, improving the safety and efficiency of wireless charging.

[0061] The present application will be further described in detail below with reference to the accompanying drawings.

[0062] In an embodiment, as Figure 1 shown, the present application discloses an earphone wireless charging management method, which specifically includes the following steps:

[0063] S10: Obtain the wireless charging start information of the mobile power supply.

[0064] Specifically, the start signal of the mobile power supply is detected through the button trigger method. When the user presses the start button, the main control unit of the mobile power supply captures the signal change generated by the button press through the voltage detection circuit, thereby activating the power management module; or it is started by detecting the Q value of the wireless charging system. The detection circuit is used to obtain the loss ratio of the resonant circuit, and the Q value is calculated after measuring the stored energy and loss energy in one cycle. If the Q value is greater than the preset start threshold, the mobile power supply is awakened to enter the working state. If the Q value is lower than the start threshold, it remains in the standby state, and at the same time, the hardware interrupt mechanism is used to ensure the fast response of the start signal.

[0065] S20: According to the wireless charging start information, judge whether there is a mobile device on the wireless charging coil of the mobile power supply. If there is a mobile device on the wireless charging coil, generate device connection information.

[0066] Specifically, after the mobile power supply is started, a high-frequency alternating magnetic field is emitted through the wireless charging coil to detect whether a receiving coil enters the magnetic field range. If the receiving coil enters the magnetic field, an induced current will be generated in the receiving resonant circuit and a communication signal will be sent to the transmitting end through the load regulation method. The communication signal includes signal strength information and device identification information. The transmitting end analyzes the received signal content, verifies whether the communication protocol meets the standard (such as packet 0x01 or packet 0x71), extracts the device identification field and signal strength information, and generates device connection information when the signal verification passes.

[0067] S30: Confirm the device type of the device connection information through the device information database to obtain the device type information. If the device type information is a headset, generate headset charging mode information

[0068] Specifically, analyze the device connection information fed back by the receiving end, compare the device identification field with the standard in the device information database. The comparison process includes extracting the key bytes in the device identification information. If the key bytes match the characteristics of the headset device, such as the second byte of the message of packet 0x71 (identification packet) is 0x00, the third byte is 0x5A, and the seventh byte is not 0x67, 0x68 or 0x69, and at the same time no extended identification packet (such as packet 0x81) is received, the device is initially confirmed to be a headset. Further, by analyzing the power demand information, if the power demand is less than the maximum power limit of the headset, the device is finally confirmed to be of the headset type and headset charging mode information is generated. The charging mode information includes charging power parameters, communication protocol support rules, and temperature control strategies.

[0069] S40: Charge the headset according to the headset charging mode information, and during the charging process, the system continuously obtains the headset temperature information.

[0070] In this embodiment, the system refers to the overall working mechanism jointly composed of the wireless charging transmitting end and the headset. The headset detects the internal temperature in real time through a built-in temperature sensor and adjusts the charging behavior, while the wireless charging transmitting end dynamically adjusts the charging power according to the load characteristic changes or communication signals fed back by the headset. The two jointly realize the monitoring and management of the headset charging process, ensuring the safety and stability of charging.

[0071] Specifically, the wireless charging transmitting end adjusts the frequency and duty cycle of the PWM signal according to the power parameters set in the headset charging mode information to provide charging power for the headset. The headset internally monitors the temperature of its key components in real time through a temperature sensor. The temperature value detected by the headset is not transmitted to the transmitting end through the wireless charging communication protocol. Instead, the headset processes the temperature data according to the temperature control strategy internally and indirectly reflects the temperature state by adjusting the load characteristics. The transmitting end adjusts the output power according to the load feedback signal of the headset to ensure the safety of the charging process.

[0072] S50: Compare the temperature information collected inside the earphone with the preset earphone temperature threshold. If the earphone temperature information exceeds the preset earphone temperature threshold, the earphone turns off the wireless charging function and generates processed earphone temperature information. If the earphone temperature information is lower than the preset earphone temperature threshold, the wireless charging function is turned on and continued charging information is generated.

[0073] Specifically, the temperature sensor inside the earphone collects the current temperature information in real time, and compares the collected temperature data item by item with the preset earphone temperature threshold. The comparison process uses a logic judgment mechanism. When the temperature information exceeds the threshold, the earphone generates processed earphone temperature information and immediately triggers the high-temperature protection mode. At this time, the earphone stops receiving the wireless charging power, and at the same time disconnects the communication connection with the wireless charging transmitter and enters the cooling state. During the cooling process, the internal control unit of the earphone monitors the temperature change and re-detects whether the temperature has returned to the safe range through a preset time interval until the temperature is lower than the temperature threshold. When the earphone temperature returns to the threshold range, the earphone generates continued charging information, re-establishes the communication connection with the wireless charging transmitter, and sends a resume charging instruction. The wireless charging transmitter restores the output power to the normal range according to the earphone charging mode information, and the earphone enters the safe charging state.

[0074] In one embodiment, as Figure 2 shown, in step S20, that is, according to the wireless charging start information, it is judged whether there is a mobile device on the wireless charging coil of the mobile power supply. If there is a mobile device on the wireless charging coil, device connection information is generated, and it further includes:

[0075] S201: If there is no mobile device on the wireless charging coil, mobile power supply shutdown information is generated.

[0076] Specifically, after detecting the wireless charging start information, a high-frequency magnetic field is emitted through the wireless charging coil, and the transmitter judges in real time whether there is a receiving-end device entering the magnetic field range through the feedback signal of the resonant circuit. During the detection process, the transmitter confirms the presence of the device by analyzing whether a signal conforming to the communication protocol (such as a 0x01 packet or a 0x71 packet) is received. If no valid signal is detected within the set time window, it is considered that there is no mobile device on the wireless charging coil. At this time, the controller triggers the shutdown logic and generates mobile power supply shutdown information.

[0077] In one embodiment, as Figure 3 shown, in step S30, that is, the device type is confirmed for the device connection information through the device information database to obtain device type information. If the device type information is an earphone, earphone charging mode information is generated, including:

[0078] S301: Obtain the device power demand information and device communication characteristic information from the device connection information.

[0079] Specifically, by parsing the communication protocol message in the device connection information, extract the device identification field and the power demand field in the data packet. The power demand field contains the charging power demand range and the current power request value of the device. During the parsing process, by parsing the content of the message byte by byte, verify the integrity and consistency of the data structure, and verify the validity of the data in combination with the check code to ensure the accuracy of the power demand information. The extraction of the device communication characteristic information is performed by analyzing the protocol type, field identifier, and additional attribute field of the data packet, including determining whether there are specific key identification characteristics in the data packet, such as whether it contains an extended identifier (such as packet 0x81) or has a specific field value (such as the key byte value of packet 0x71). The extracted power demand information and communication characteristic information are processed by the protocol parsing module, converted into structured information, and stored in the temporary cache in the form of key-value pairs to provide a basis for subsequent comparison of the device type.

[0080] S302: If the device power demand information meets the headset power demand standard in the device information database and the device communication characteristic information meets the headset communication protocol type in the device information database, confirm the device type and generate device type information.

[0081] Specifically, compare the extracted power demand information with the headset power demand standard recorded in the device information database. The comparison process includes parsing the numerical value of the power demand field and comparing it one by one with the upper and lower limits of the headset power demand stored in the database to confirm whether the device's power demand is within the headset standard range; if the power demand is within the standard range, it is considered that the power demand information meets the headset characteristics. In addition, check the device communication characteristic information item by item with the headset communication protocol type in the device information database, including verifying whether the communication protocol message contains fields that meet the headset characteristics (such as the specific identification packet 0x71), whether there is no extended identification packet that the headset does not support (such as packet 0x81), and whether the key field value matches the communication identification rule of the headset. During the verification process, comprehensively judge the characteristic fields through logical rules to ensure the rigor of the matching conditions. If both the power demand information and the communication characteristic information meet the headset standard, confirm that the device type is a headset and generate information indicating that the device type is a headset.

[0082] S303: If the device type information is a headset, generate headset charging mode information.

[0083] Specifically, after confirming that the device is a headset based on the device type information, retrieve the charging mode parameters corresponding to the headset from the device information database, including the maximum charging power supported by the headset, the type of communication protocol, the high-temperature protection strategy, and the recharge rule. Since the wireless charging transmitter cannot directly obtain the temperature, voltage, and current information inside the headset, nor can it transmit this data through the communication protocol, the charging mode information sets the response rules for the feedback behavior of the headset. For example, the headset detects the temperature internally. When the temperature exceeds the preset threshold, the headset will actively adjust the load characteristics, such as changing the resonance frequency or impedance value, to indirectly reflect the abnormal temperature state to the transmitter. The headset charging mode information contains the logic for processing such feedback. When the transmitter detects a load change, it enters the intermittent charging mode, providing sufficient cooling time for the headset by reducing the output power or briefly stopping the charging. The headset charging mode information also includes the rule for resuming charging after high temperature. When the internal temperature of the headset returns to the safe range, the headset will notify the transmitter that it can resume charging by adjusting the load characteristics or re-establishing communication, and the transmitter will adjust the output power to the normal range according to the charging mode information and resume the charging process.

[0084] Furthermore, after confirming the headset based on the device type information, set the charging mode information of the headset and enter the charging mode of cyclic timed switching of the output power through the wireless charging mobile power supply. This mode is controlled by the PWM peripheral module of the MCU. When the PWM signal is off, the power output stops; when the PWM signal is on, the output frequency is set to 128 KHz and the duty cycle is 30%. A complete cycle is divided into two steps: The first step is short-time power output, which lasts for 100 microseconds and then turns off, entering a standby state for 250 milliseconds, and repeating 4 times; the second step is a single longer-time power output, which lasts for 90 milliseconds and then turns off. During each power output period, the MCU uses a high-precision ADC to collect the output current value in real time, records the dynamic change of the output power at the same time, and analyzes the actual charging demand of the headset. By calculating the current difference between the off state and the working state (working current - off current), the power output is dynamically adjusted to optimize the charging efficiency of the headset. In addition, during the power output gap, the mobile power supply enters the low-power standby mode to reduce energy consumption. In the high-temperature state of the headset, the power output is gradually reduced by adjusting the PWM duty cycle to enter the intermittent charging mode to control the temperature of the headset. When the temperature of the headset returns to the safe range, it is automatically adjusted to the normal charging mode and the continuous power output is resumed.

[0085] In one embodiment, as Figure 4 shown, in step S302, that is, if the device power demand information meets the headset power demand standard in the device information database and the device communication characteristic information meets the headset communication protocol type in the device information database, then confirm the type of the device, generate the device type information, and further include:

[0086] S3021: If the device power demand information does not conform to the headset power demand standard in the device information database and / or the device communication feature information does not conform to the headset communication protocol type in the device information database, then confirm that the mobile device is a non-headset device.

[0087] Specifically, compare the power demand field in the device connection information with the headset power demand standard in the device information database. If the comparison result shows that the power demand exceeds the standard range of the headset, record the power demand mismatch information. At the same time, analyze the device communication feature field, including detecting whether the data packet contains an extended identification packet (such as the 0x81 packet) or judging whether the value of a specific key byte conforms to the headset communication feature. If it is detected that the communication feature does not conform to the headset protocol standard, record the communication protocol mismatch information. When any one of the power demand information or the communication feature information does not conform to the headset standard, immediately confirm that the device is a non-headset device and mark it as a normal charging device.

[0088] S3022: If the mobile device is a non-headset device, generate normal charging mode information.

[0089] Specifically, after confirming that the device is a non-headset device, retrieve the adapted normal charging mode parameters from the database according to the power demand and communication feature recorded in the device connection information. This mode information includes the maximum supported power of the device, the standard charging protocol type, and the safety protection strategy. Generate the charging mode information by combining the actually detected device parameters. The generated normal charging mode information specifically includes PWM control parameters, charging current range, and overcurrent protection threshold. At the same time, set a basic temperature monitoring strategy to ensure the safety of device charging.

[0090] In one embodiment, as Figure 5 shown, in step S40, that is, processing the headset temperature information, including:

[0091] S401: According to the processed headset temperature information, calculate the current power output value through the battery power, temperature, and power demand of the headset, and use the current power output value as the wireless charging output power.

[0092] Specifically, when the headset temperature exceeds the high temperature threshold, calculate the current power output value according to the real-time data feedback by the headset, including battery power, temperature information, and power demand, in combination with the optimized dynamic temperature control algorithm in the wireless charging system. The temperature control algorithm is based on the following formula: , where, P output is the current power output value, P max is the maximum charging power supported by the headset, T is the current temperature of the headset, T safe is the upper limit of the safe temperature range, T max is the maximum allowable critical temperature, Psafe The safety power threshold set to prevent further temperature rise, α is the sensitivity index of temperature to power adjustment, which is used to dynamically adjust the attenuation speed of the output power, β is the power priority coefficient, which is used to increase the charging power in the low battery state, and g(E) is a non-linear adjustment function of the battery power, which provides additional power compensation when the power is below 20%. When the headset temperature approaches T max , the algorithm preferentially reduces the output power to P saf e to avoid further temperature rise. At the same time, for the case of low battery (such as less than 20%), a proper charging power boost is provided through the non-linear compensation function g(E) to balance the battery requirements and temperature safety of the headset. The calculated power value is applied to the wireless charging output terminal in real time through a PWM signal, and the output parameters are dynamically adjusted to adapt to the temperature and power changes of the headset, ensuring that the charging process is both safe and efficient.

[0093] S402: If the headset temperature information returns to the preset headset temperature threshold, generate headset temperature recovery information. According to the headset temperature recovery information, restore the wireless charging output power to the preset normal charging power.

[0094] Specifically, by real-time monitoring the temperature information fed back by the headset and comparing it with the preset headset temperature threshold, when the headset temperature drops below the high temperature threshold, record the current time point and generate headset temperature recovery information, which includes the temperature value at the time of recovery, the battery power state, and the power demand value. Subsequently, adjust the wireless charging output power to the preset normal charging power, specifically by reading the maximum supported charging power parameter recorded in the headset charging mode information and resetting the duty cycle and frequency of the PWM control signal to restore normal wireless charging output.

[0095] In one embodiment, as Figure 6 shown, in step S402, that is, if the headset temperature information returns to the preset headset temperature threshold, generate headset temperature recovery information. According to the headset temperature recovery information, restore the wireless charging output power to the preset normal charging power, and further include:

[0096] S4021: If the headset is removed from the wireless charging coil during the cooling process, generate headset out-of-coil information.

[0097] Specifically, during the earphone cooling process, the wireless charging mobile power supply controls the output power in real time through the PWM peripheral of the MCU and detects the change of the output current through a high-precision ADC. When the earphone is removed from the charging coil, the transmitting end monitors that the load characteristics change significantly, such as an instantaneous drop in the output current or an offset of the resonant frequency. At this time, the PWM signal controls the output power to be turned off, and the mobile power supply enters the low-power detection mode, cyclically outputting power to verify the load status. In the cyclic mode, the transmitting end executes according to a preset two-step cycle: the first step is to output power for a short time, lasting 100 microseconds and then turning off for 250 milliseconds. By calculating the difference between the working current and the off current (working current - off current), if the calculated result is lower than the software-set threshold (such as 130), it is determined that the earphone has left the coil; the second step is to output power for a long time, lasting 90 milliseconds, to verify whether the load has returned to normal. If all the detection results during the entire cycle indicate that the earphone is not within the range of the charging coil, information that the earphone has been removed from the coil is generated.

[0098] S4022: Pause the wireless charging output power according to the information that the earphone has been removed from the coil.

[0099] Specifically, after generating the information that the earphone has been removed from the coil, the control module of the wireless charging transmitting end controls the PWM signal to turn off the output power signal. Specifically, the transmitting end sets the PWM duty cycle to 0, completely stops the energy transfer of wireless charging, and places the power module of the transmitting end in the low-power standby state. At the same time, before the earphone is placed back on the coil, no high-frequency magnetic field is emitted to prevent energy loss and interference.

[0100] In one embodiment, as Figure 7 shown, after step S50, that is, the earphone wireless charging management method further includes:

[0101] S501: Obtain the battery voltage information and battery current information of the earphone.

[0102] Specifically, the battery voltage information and current information are obtained in real time through the wireless charging communication protocol.

[0103] S502: Judge whether there is a charging abnormality in the battery voltage information and battery current information through a preset charging status detection model. If there is an abnormality in the battery voltage information and battery current information, charging protection measure information is generated.

[0104] Specifically, the obtained charging status information is input into a preset charging status detection model. This model analyzes charging anomalies based on a comprehensive judgment rule of multiple parameters. The detection model includes the following main judgment conditions: If the battery voltage exceeds the normal range (for example, is lower than 3.0V or higher than 4.2V), it is determined that the voltage is abnormal. If the charging current fluctuation exceeds the set stability threshold, it is determined that the current is abnormal. When the detection model outputs an abnormal result, charging protection measure information is immediately generated. The protection measure information includes instructions to reduce the charging power, intermittently stop charging, or completely stop charging.
