Description

Technical Field

[0001] The present invention relates to the technical field of hearing aids, and in particular to a production and testing method and device for a special hearing aid, and the hearing aid. Background Art

[0002] As a high-precision portable medical device, the core functions of hearing aids include sound collection, signal processing, amplification and output, etc., which require the implementation of complex functions in a miniaturized design. Hearing aids rely on a variety of sensors to achieve core functions, including microphones for sound collection and direction positioning, environmental sensors to optimize sound processing algorithms, motion sensors to dynamically adjust volume modes, and health monitoring sensors (such as heart rate and temperature sensors) to expand functions. In addition, sensors support feedback suppression, noise suppression, and user interaction, so that hearing aids can not only improve the hearing experience, but also gradually develop towards intelligence and health management.

[0003] Since special hearing aids are usually powered by small-capacity batteries, battery life is an important measure of user experience. However, special hearing aids are highly sensitive to energy consumption. Once the energy consumption is too high, it will significantly affect the battery life of the device and may not meet the user's needs for all-day wear. Therefore, in-depth analysis and optimization of the energy consumption sources of hearing aids are of great significance to improving product performance.

[0004] Functional testing is the core function of the certification equipment, including the sound collection performance of the microphone, the noise reduction and echo suppression capabilities of the signal processor, the signal output characteristics of the amplifier, and the sound playback quality of the speaker. The purpose of functional testing is to ensure that the hearing aid can achieve the designed function under a specific working mode. Energy consumption testing is to measure the total power consumption of the hearing aid under different working conditions to verify whether it is within the design target range.

[0005] The design and configuration of hearing aids determine their energy consumption performance. For example, insufficiently optimized circuit design, ineffective control of static energy consumption in standby mode, or inefficient power management modules can significantly increase total energy consumption. In addition, the manufacturing process of hearing aids uses surface mount technology (SMT), and its process quality directly affects the energy consumption performance of the product. For example, welding defects in the SMT process may cause abnormal increase in circuit impedance, thereby increasing current loss. Residual solder after welding may cause parasitic circuits, resulting in unnecessary current consumption.

[0006] In the hearing aid testing process, function testing and energy consumption testing are often treated as independent links. This independent testing mode has its advantages, but lacks correlation analysis between the two. If the function test passes but the energy consumption exceeds the standard, the traditional testing process is difficult to quickly locate the root cause of the problem. Especially in complex special hearing aid products, high energy consumption may come from many factors, not just the design of the functional module itself. Summary of the invention

[0042] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Combine the following Figure 1-Figure 4 The invention describes a production detection method, a device and a hearing aid for a special hearing aid.

[0044] The hearing aid of the present invention includes a printed circuit board and various functional devices integrated on the printed circuit board, and the functional devices include a pickup, a signal processor, an amplifier, and a receiver. The hearing aid of the present invention uses a printed circuit board (PCBA) as a core hardware carrier and integrates the following key functional devices, each of which assumes a different core function of the hearing aid and jointly achieves the purpose of hearing enhancement:

[0045] The pickup, or microphone, is responsible for collecting sound waves in the external environment and converting them into electrical signals. It is the starting point of hearing aid sound processing.

[0046] The microphone can be a single or multiple highly sensitive microphones that are used to capture the frequency, intensity, and directionality of the sound. The multi-microphone array can achieve directionality enhancement and ambient noise suppression to improve speech clarity. The microphone can also be equipped with an anti-wind noise design to adapt to complex listening environments.

[0047] The signal processor digitizes the electrical signal collected by the pickup and executes various sound optimization algorithms, such as noise reduction, feedback suppression, gain adjustment, and speech enhancement. The signal processor contains a high-speed digital signal processing unit (DSP) to achieve real-time audio processing and supports a variety of algorithms, such as frequency segmentation, dynamic range compression (DRC), and directionality optimization, which can adapt to different hearing loss patterns and adjust the output of the hearing aid through programming.

[0048] The amplifier amplifies the weak signal output by the signal processor to ensure that the signal strength is sufficient to drive the receiver while maintaining signal clarity. The amplifier includes a low noise amplifier (LNA) and a power amplifier (PA), which are used for primary signal amplification and output signal driving respectively.

[0049] The receiver, or speaker, can convert the amplified electrical signal into sound waves and transmit them directly to the user's ear canal to reproduce the sound.

[0050] Receivers usually use micro dynamic or piezoelectric speakers, which are highly efficient and small in size. Receivers support a wide frequency response range to meet the perception needs of users with different hearing losses for sound frequencies. Receiver design focuses on the clarity and comfort of the output sound to avoid harsh or distorted sound quality.

[0051] The printed circuit board is used as a carrier to integrate the above functional devices together, and through precise wiring, efficient electrical connections between the functional devices are achieved. In this way, the PCBA of the hearing aid can be designed compactly to meet the requirements of lightweight and miniaturized hearing aids.

[0052] The embodiments of the present invention highly integrate the microphone, signal processor, amplifier and receiver on a printed circuit board to form a compact and efficient functional architecture, which can collect, process and amplify sound signals with high quality and provide users with a clear and natural auditory experience. It adapts to the trend of miniaturization, intelligence and low energy consumption of hearing aids and meets the needs of users with different degrees of hearing loss.

[0053] The production and testing method of the special hearing aid of the present invention mainly includes step 110 , step 120 , step 130 , step 140 and step 150 .

[0054] Step 110 , detecting at least one of a current and a voltage of each functional device in a printed circuit board of the hearing aid to be tested under a target detection configuration.

[0055] The test configuration is used to simulate the working mode of the hearing aid. The target test configuration refers to the test environment configuration set to simulate the actual working mode of the hearing aid. In this configuration, the various functional components of the hearing aid are in operation, and their working performance and energy consumption are analyzed by detecting current and voltage.

[0056] In the target detection configuration, each functional component on the hearing aid printed circuit board is tested by setting a specific operating mode (such as simulating actual usage status). The current or voltage (or both) can be measured to evaluate whether each functional component works as expected. The target detection configuration simulates the typical usage scenario of the hearing aid, which can include factors such as different volume settings and ambient noise levels to ensure that the performance of the functional components under different conditions can be fully evaluated.

[0057] It is understandable that the power on / off test can be started on the printed circuit board PCBA first. The PCBA can be placed in the fixture area, and the spring pins on the fixture can be used to contact the test points on the PCBA. The test points on the PCBA can be connected to the DAC and ADC pins of the microcontroller unit MCU on the test equipment. The DAC pin outputs the voltage, and then the voltage is read from the ADC pin at the other end of the capacitor. The whole process takes 10 milliseconds. If the ADC voltage is not equal to the DAC voltage, and the voltage fluctuation is detected when the DAC is started, it can be determined that the two ends of the capacitor are electrically correct, that is, the voltage rails at both ends of the capacitor are correct.

[0058] Secondly, start controlling the MOS tube to power the hearing aid PCBA, and detect the voltage at both ends of the specified capacitor. The high voltage side of this capacitor is connected to the ADC pin of the MCU. Due to the operation of the internal boost circuit of the hearing aid, the voltage of this capacitor can reach between 1.8V and 2.0V. If the voltage is correct, it means that the boost part of the hearing aid is working properly. If the MCU is connected to the hearing aid PCBA communication pin, the MCU controls the buzzer in the fixture to sound or mute, and reads the response value of the pickup by communicating with the hearing aid. The value should be within the empirical value range, which proves that the pickup function of the hearing aid is normal.

[0059] The hearing aid receiver can also be controlled through the communication line to emit pure tones with fixed frequencies of 500 Hz and 1000 Hz in turn. The pure tones emitted by the receiver are collected by the microphone, and the MCU analyzes whether the received pure tone frequency is normal, thereby determining whether the receiver is functioning normally.

[0060] You can also implant a preset program into the hearing aid through the communication line, and then the buzzer emits a specific pure tone. At this time, check the current of the PCBA power supply circuit. This current is sampled by the sampling resistor and sent to the ADC pin of the device's MCU, and the total energy consumption is obtained to determine whether the total energy consumption meets the design requirements.

[0061] Step 120 , when the total power consumption of the printed circuit board under the target detection configuration meets a preset power consumption condition, the current and voltage of each functional component are respectively obtained.

[0062] When performing the total energy consumption test, ensure that the overall energy consumption of the hearing aid meets the predetermined standards. At this time, by measuring the current and voltage of each functional component, it can be confirmed whether the energy consumption of each functional component is within a reasonable range. If the total energy consumption exceeds the predetermined threshold, it may indicate that there is an abnormal energy consumption of a functional component, which requires further analysis and testing.

[0063] In this implementation, it can ensure that the overall energy consumption of the hearing aid meets the design requirements, avoiding battery life problems caused by excessive energy consumption. By separately obtaining the current and voltage of each functional component, the components with high energy consumption can be identified one by one, providing data support for subsequent problem location.

[0064] Step 130: Determine a function detection result and an energy consumption detection result of each functional component based on at least one of the current and the voltage of each functional component.

[0065] The energy consumption test results refer to the energy consumption information calculated by measuring the current and voltage of the hearing aid's functional components. These data help analyze the energy efficiency and battery life of the hearing aid.

[0066] According to the current and voltage data of each functional device, the working status and energy consumption of each functional device are evaluated. Through the analysis of current and voltage signals, it can be determined whether the functional device is working properly, and combined with the energy consumption data to evaluate whether it meets the predetermined energy efficiency requirements.

[0067] Step 140 , when the energy consumption detection result of at least one functional device is abnormal, based on the abnormal functional device and the function detection result of the abnormal functional device, determine a verification detection configuration for verifying the abnormal result.

[0068] The verification test configuration simulates a different operating mode than the target test configuration. The verification test configuration is a special test configuration set up to verify the abnormal detection results, which is different from the target test configuration. The verification configuration can further confirm whether the performance and energy consumption of the functional device meet the requirements by adjusting the operating mode, power setting or other operating conditions.

[0069] When abnormal energy consumption of a functional device is detected, a verification test configuration can be set in combination with the functional test results of the device (such as abnormal working status). This configuration is different from the target configuration, and the abnormality can be further confirmed by changing the working conditions such as different volume, frequency or noise processing level to determine whether the abnormality is caused by the performance problem of the device itself or the change of external conditions.

[0070] It is understandable that through review and verification, it is possible to more clearly know whether the energy consumption abnormality is caused by design defects, process problems or other external factors, thereby effectively determining the root cause of the problem. In addition, the introduction of verification configuration can avoid errors in single test results and ensure the reliability of detection.

[0071] Step 150: re-detect at least one of the current and the voltage of the functional device with abnormal energy consumption in the previous detection under the verification configuration to determine the energy consumption detection result of the hearing aid to be tested.

[0072] Retest the functional devices that showed abnormal energy consumption in the previous test under the verification configuration to obtain more accurate energy consumption data by measuring the current and voltage again.

[0073] In some embodiments, the energy consumption curve of the previous test can be compared to determine whether the energy consumption change in this test is related to the configuration change, and to confirm whether there is a design or process problem.

[0074] It is understandable that verification testing can help confirm the exact cause of abnormal energy consumption in the previous test and ensure the accuracy and reliability of the test results. If the verification results are closely related to configuration changes, the design or production process can be further optimized to avoid similar problems.

[0075] It is understandable that by establishing a connection between functional testing and energy consumption testing, these two links are no longer independent, but interdependent and complementary. By continuously comparing the energy consumption data under the target configuration and the verification configuration during the testing process, it can help distinguish whether the energy consumption abnormality is caused by design problems, configuration problems or other external factors. If the energy consumption abnormality is related to configuration changes, it can quickly help determine whether it is a design defect or improper configuration in certain specific working modes.

[0076] High energy consumption may be caused by many factors. Traditional detection methods may only detect anomalies at a certain level and cannot fully analyze the reasons for energy consumption changes. However, by reconfiguring the verification mode and analyzing energy consumption changes, this method can more clearly identify which design or process links cause energy consumption anomalies, thereby providing data support for optimizing design and improving production processes.

[0077] It is understandable that by reviewing the energy consumption data under different configurations in this embodiment, it is not only possible to find potential design problems during the test process, but also possible process defects can be found in a timely manner during the production process. For example, welding problems in the SMT process or unreasonable wiring in the circuit board design may lead to abnormal energy consumption. Through review testing, these problems can be avoided from being ignored in mass production, thereby improving the production quality of the product.

[0078] According to the production inspection method for special hearing aids provided in an embodiment of the present invention, by separately detecting the voltage and current data of each functional component and combining functional inspection with energy consumption inspection, it is possible to more accurately locate the root cause of the problem and improve test efficiency and accuracy. Especially in complex special hearing aid products, by setting a verification inspection configuration to review the product, it is helpful to discover energy consumption anomalies caused by various factors and provide strong support for design optimization and process improvement.

[0079] In some embodiments, the detection configuration includes at least one of a supply voltage to the printed circuit board, audio parameters processed by a microphone and a receiver, and processing parameters of a signal processor and an amplifier.

[0080] The power supply voltage to the printed circuit board refers to the voltage supplied to the printed circuit board, which affects the working state and energy consumption of the entire hearing aid.

[0081] Audio parameters include the frequency, amplitude and other characteristics of the audio signals processed by the microphone and receiver. Identification of these audio parameters helps to verify whether the sound signal is transmitted and processed as expected and obtain the expected energy consumption data.

[0082] The processing parameters of signal processors and amplifiers refer to the key operating parameters of signal processors and amplifiers when they are working, such as whether the signal processor turns on noise reduction, the signal-to-noise ratio of the processed data, and the amplification factor of the amplifier. These parameters ensure that they can process audio signals according to design requirements and provide appropriate amplification effects.

[0083] Based on abnormal functional devices and functional test results of the abnormal functional devices, determining a verification configuration for reviewing the abnormal results includes: based on the abnormal functional devices, determining from the test configuration a verification configuration item for reviewing the abnormal results corresponding to the abnormal functional devices; based on the abnormal functional devices and functional test results of the abnormal functional devices, adjusting parameters in the verification configuration item for reviewing the abnormal results to obtain a verification test configuration.

[0084] When it is found during the detection process that some functional components such as a pickup, an amplifier, etc. have abnormal energy consumption, the verification configuration can be determined based on the abnormal functional components and their functional detection results.

[0085] You can first find the configuration items related to the abnormal functional device from the detection configuration. These configuration items will help further verify the cause of the abnormality. According to the abnormal functional device and its detection results, adjust the relevant parameters in the verification configuration.

[0086] It is understandable that by adjusting these parameters, the verification configuration can be made more adaptable to the needs of troubleshooting anomalies so as to locate the problem more accurately. The verification configuration can perform more in-depth detection on the functional devices where the anomalies are found, ensuring that the problem can be accurately identified and resolved in subsequent steps.

[0087] In some embodiments, at least one of the current and the voltage of the functional device with abnormal energy consumption in the previous detection is re-detected under the verification configuration to determine the energy consumption detection result of the hearing aid to be tested, including step 210 and step 220.

[0088] Step 210, under the verification configuration, re-detect the current and / or voltage of the functional device with abnormal energy consumption, and generate a verification energy consumption curve;

[0089] Step 220 , extracting energy consumption features from the verification energy consumption curve and the energy consumption curve detected last time, respectively, and determining whether the energy consumption change is correlated with the change of the verification configuration based on the energy consumption features.

[0090] Under the verification configuration, the current and / or voltage of the functional device that showed abnormal energy consumption in the previous detection is re-detected, and a verification energy consumption curve is generated. The verification configuration can refer to a working mode or parameter setting that is different from the initial detection. It is used to troubleshoot potential problems that cannot be found under the target configuration.

[0091] Adjustments to the verification configuration may include changing the frequency of the audio signal, changing the power supply voltage, or modifying other processing parameters to simulate different operating environments or conditions.

[0092] The validation energy consumption curve is a graph based on retested data that shows the current and voltage changes of a functional device under specific operating conditions.

[0093] Assume that the hearing aid amplifier is found to have abnormal energy consumption during the initial test. First, the current and voltage of the amplifier can be retested in the verification configuration. If the input signal in the configuration is adjusted, such as changing the amplification parameters, this will affect the working state of the amplifier, thereby generating a new verification energy consumption curve.

[0094] Energy consumption features are extracted from the verification energy consumption curve and the energy consumption curve of the previous detection, and the difference between the two is analyzed to confirm whether the energy consumption change is related to the change of the verification configuration.

[0095] Energy consumption characteristics may include key data characteristics such as total energy consumption, energy consumption fluctuations at specific frequencies, and different current and voltage change rates.

[0096] By comparing and verifying the energy consumption curve with the energy consumption curve of the previous detection, it is possible to analyze whether the configuration change has an impact on energy consumption, and then determine whether the configuration adjustment can help locate and resolve energy consumption anomalies.

[0097] In the previous test, the receiver's energy consumption curve showed abnormally high energy consumption fluctuations. After adjusting the verification configuration, such as increasing the input signal frequency, the receiver's working state may change, thereby changing its energy consumption characteristics. At this time, comparing the energy consumption curves of the two tests, it may be found that the receiver's energy consumption performance at different frequencies varies greatly. At this time, by analyzing these characteristics and confirming that there is a correlation between energy consumption changes and changes in verification configurations, it is possible to further analyze that the cause of high energy consumption may be due to design problems or improper configuration.

[0098] It is understandable that by retesting and generating verification energy consumption curves, extracting energy consumption characteristics and analyzing correlations, we can have a deeper understanding of the energy consumption performance of various functional components of hearing aids under different working modes, help identify the root causes of abnormal energy consumption, thereby improving the accuracy of detection and optimizing the design and performance of hearing aids.

[0099] In some embodiments, when the functional device with abnormal energy consumption detection results is a signal processor or an amplifier, the parameters in the verification configuration item used to review the abnormal results are adjusted to obtain the verification detection configuration, including: adjusting the signal-to-noise ratio in the processing parameters of the signal processor or the amplification parameters in the processing parameters of the amplifier in the verification configuration item used to review the abnormal results to obtain the verification detection configuration.

[0100] During the detection process, if the energy consumption of the signal processor or amplifier is found to be abnormal, that is, their current, voltage and energy consumption values ​​are not as expected, it indicates that there may be problems with their working status.

[0101] In order to solve the problem of abnormal energy consumption, the working conditions of these devices under different conditions can be compared and verified by adjusting the parameters in the verification configuration.

[0102] The signal-to-noise ratio of a signal processor is a measure of the ratio between the signal quality and the noise when the signal processor receives an audio signal. The higher the signal-to-noise ratio, the clearer the signal and the smaller the noise impact. By adjusting the parameters of the signal-to-noise ratio, you can simulate different working environments to see whether the energy consumption performance of the signal processor is different when the signal-to-noise ratio changes.

[0103] If the energy consumption abnormality is related to the signal-to-noise ratio setting, it may mean that the signal processor is not efficient enough when processing certain signals, resulting in additional energy consumption. Therefore, it may be a design or configuration problem. If the energy consumption is high after the signal-to-noise ratio changes but the difference with the previous test result is not big, it means that there may be no problem with the design, but it is only related to the quality of the manufacturing process.

[0104] For an amplifier, the amplification parameters (such as gain or gain) in its processing parameters directly affect the amplifier's amplification of the input signal. An amplifier gain that is too high may lead to over-amplification of the signal, thereby increasing energy consumption. Therefore, adjusting the settings of the amplification parameters (such as reducing the gain) can help determine whether the amplifier settings are too aggressive, resulting in abnormal energy consumption.

[0105] It is understandable that by adjusting the above parameters, a new verification test configuration can be formed. The new configuration settings will be used to re-test the energy consumption of the signal processor or amplifier under the new parameters, thereby helping to determine whether there is a design problem or improper configuration that causes abnormal energy consumption.

[0106] Assume that in the initial test, it is found that the energy consumption of the amplifier is abnormally high. This may be due to the extra energy consumption caused by its excessive gain. In this case, adjust the amplifier gain in the verification configuration item, reduce the gain value, and re-test the energy consumption data of the amplifier. If the energy consumption returns to normal after the re-test, it can be inferred that the abnormal energy consumption is caused by the excessively high gain setting.

[0107] In other words, when a signal processor or amplifier has abnormal energy consumption, by adjusting processing parameters such as the signal-to-noise ratio (signal processor) or amplification gain (amplifier), forming a new verification configuration, and re-testing its energy consumption, it can help confirm whether the settings of these parameters have caused the high energy consumption problem.

[0108] In some embodiments, when the functional device with an abnormal energy consumption detection result is a microphone or a receiver, the parameters in the verification configuration item used to verify the abnormal result are adjusted to obtain a verification detection configuration, including: adjusting the power supply voltage to the printed circuit board in the verification configuration item used to verify the abnormal result, and adjusting the frequency and amplitude in the audio parameters processed by the microphone or the receiver to obtain the verification detection configuration.

[0109] During the test, if the energy consumption of the microphone or receiver is found to be abnormal, it means that their energy consumption is not in line with expectations. This may be due to the design of the device itself, or the inappropriate environment configuration when they are working. Therefore, it is necessary to adjust some working parameters for verification to determine the root cause of the abnormal energy consumption.

[0110] The supply voltage is one of the key factors that affect the working state of a microphone or receiver. If the supply voltage is too high or too low, it may cause the device to consume excessive energy, resulting in abnormal energy consumption. Therefore, adjusting the supply voltage of the printed circuit board can help simulate the performance of the device under different voltage conditions and verify whether the abnormal energy consumption is caused by unstable voltage.

[0111] The main function of microphones and receivers is to process audio signals. The frequency and amplitude of the audio will also directly affect their energy consumption.

[0112] Different frequencies require different response capabilities of the microphone or receiver to the signal. If the frequency is set too high or too low, it may cause the device to process the signal inefficiently, thereby consuming more power.

[0113] The amplitude of an audio signal determines the strength of the signal. A larger amplitude may cause the microphone or receiver to require more power to process the signal, which in turn increases energy consumption.

[0114] It is understandable that by adjusting these audio parameters, it can be verified whether the abnormal energy consumption performance is caused by unreasonable settings of frequency and amplitude.

[0115] In this embodiment, by adjusting the above parameters such as power supply voltage, frequency, amplitude, etc., a new verification detection configuration can be generated, and the working condition of the microphone or receiver can be re-detected according to the configuration, so as to determine the root cause of the abnormal energy consumption, whether it is due to improper voltage, audio parameter configuration problems, or other factors that cause increased energy consumption.

[0116] Suppose that during initial testing, it is discovered that the power consumption of the pickup is abnormally high. Possible reasons include: the operating voltage of the pickup is too high, causing it to consume too much power; or the audio frequency or amplitude being processed is too large, causing the device to require more energy to process the audio signal.

[0117] To verify these reasons, you can adjust the following parameters: You can adjust the supply voltage to simulate the change in energy consumption of the pickup under different voltage conditions; you can also adjust the frequency and amplitude of the audio signal to check the change in energy consumption under these changes.

[0118] It is understandable that through these adjustments, it is possible to verify whether it is the unreasonable settings of these parameters that lead to the abnormal energy consumption of the pickup, thereby further locating the problem and optimizing the design or configuration.

[0119] When abnormalities are found in the microphone or receiver during energy consumption detection, the performance of these functional components under different working conditions can be simulated by adjusting parameters such as the power supply voltage, frequency, and amplitude in the verification configuration items, providing strong support for troubleshooting and solving high energy consumption problems.

[0120] In some embodiments, the printed circuit board also includes a memory, and the production detection method of the special hearing aid of the embodiment of the present invention also includes: writing data to different areas of the memory, reading data at different addresses after powering off and powering on the printed circuit board, and comparing the data with the written data.

[0121] In hearing aids, memory such as EEPROM is used to store some key configuration information or device status data. The data in the memory needs to be consistent and readable throughout the use of the hearing aid.

[0122] During the production test process, data needs to be written to different areas of the memory first. Each area may represent a different function or store different characteristic values. For example, some specific characteristic values ​​such as production serial number, calibration parameters, configuration information, etc. can be written to different sectors of the EEPROM.

[0123] After writing the data, the hearing aid’s printed circuit board PCBA is powered off and then powered back on. This process simulates the power outages and restarts that the device may experience in daily use. The purpose is to ensure that the data in the memory can still be correctly saved after the power is off and restored when the power is turned on again.

[0124] After power is turned on again, the data at the specified address in the memory is read through the communication line and compared with the previously written data. If the read data is consistent with the written data, it means that the data reading and writing function of the memory is normal and the previously written value can be correctly read after power is turned on.

[0125] In this embodiment, it can be ensured that the memory in the hearing aid, such as EEPROM, can correctly save and read data. In production testing, writing characteristic data and verifying it by power off and restarting can confirm whether the memory functions normally, ensuring that key configuration data will not be lost or read incorrectly due to power off in actual use.
