[0018] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] The implementation of the present invention will be described in detail below in conjunction with specific embodiments.

[0020] Refer to Figure 1 、 Figure 2 As shown, a preferred embodiment is provided by the present invention.

[0021] In a first aspect, the present invention provides a method for optimizing the signal reception sensitivity of a low-power dual-mode Bluetooth chip, including:

[0022] S1: Real-time detect the signal reception environment of the Bluetooth chip to obtain the signal environment characteristics of the Bluetooth chip;

[0023] S2: Switch the working mode of the Bluetooth chip according to the signal environment characteristics to switch the Bluetooth chip to the precise mode or the low-power mode corresponding to the signal reception environment;

[0024] S3: When the Bluetooth chip is in the precise mode or the low-power mode, perform real-time dynamic adjustment of the radio frequency communication parameters and demodulator parameters of the Bluetooth chip according to the signal parameter adjustment scheme corresponding to the precise mode or the low-power mode, so that the signal reception sensitivity of the Bluetooth chip is at a specified standard;

[0025] S4: Synchronously monitor the signal effect of the Bluetooth chip, adjust and optimize the signal parameter adjustment scheme according to the results of the synchronous monitoring, and continue to perform real-time dynamic adjustment of the radio frequency communication parameters and demodulator parameters of the Bluetooth chip through the adjusted and optimized signal parameter adjustment scheme.

[0026] Specifically, in step S1 of the embodiment provided by the present invention, the received signal strength is collected in real time through the received signal strength indicator (RSSI) function built into the Bluetooth chip. This function can reflect the strength of the signal in the current environment, helping to judge the basic situation of the signal quality, measuring the signal power and noise power received by the Bluetooth chip. The signal power represents the strength of the received signal, and the noise power is the strength of the interference signal. The ratio of the two is used for subsequent signal-to-noise ratio (SNR) calculation. Based on the values of the signal power and noise power, the signal-to-noise ratio (SNR) is calculated. The signal-to-noise ratio is a key indicator for evaluating signal quality. A high signal-to-noise ratio usually means better communication quality, while a low signal-to-noise ratio means that the received signal may be subject to significant interference. The bit error rate (BER) is monitored, that is, the ratio of errors when receiving data. The level of the bit error rate can directly reflect the stability and transmission quality of the signal. A higher bit error rate usually indicates poor signal quality and requires adjustment of the receiving process.

[0027] More specifically, information such as signal strength, signal-to-noise ratio, and bit error rate is comprehensively analyzed to obtain the signal reception environment characteristics of the Bluetooth chip. By combining and processing these parameters, the quality of the signal environment can be comprehensively evaluated. Through real-time monitoring of signal strength, signal-to-noise ratio, and bit error rate, the quality of the current signal can be effectively perceived, which provides an important basis for subsequent mode switching and signal adjustment. By comprehensively analyzing the signal environment characteristics, the Bluetooth chip can dynamically adjust the working mode (such as precision mode or low-power mode) according to the actual situation, so as to ensure good performance in different environments. Accurately detecting and analyzing the signal environment helps to optimize the signal reception ability of the Bluetooth chip. For example, if the signal-to-noise ratio is low, the system can adjust the parameters to improve the reception sensitivity; if the bit error rate is high, the system can make appropriate gain adjustments or switch the working mode to reduce errors. Through comprehensive analysis of signal quality, a response can be made in a timely manner in an environment with poor signal quality, reducing the bit error rate and improving the reliability of data transmission. The ability of real-time monitoring and dynamic adjustment enables the Bluetooth chip to intelligently adapt to environmental changes and maintain the best performance and energy efficiency under different environmental conditions.

[0028] Specifically, in step S2 of the embodiment provided by the present invention, the Bluetooth chip continuously obtains signal environment characteristics, such as received signal strength (RSSI), signal-to-noise ratio (SNR), bit error rate (BER), etc. These parameters jointly determine the current signal quality. If the signal strength is high, the signal-to-noise ratio is good (i.e., signal interference is small), and the bit error rate is low, it indicates that the signal environment is good. If the signal strength is weak, the signal-to-noise ratio is low (i.e., noise is strong), and the bit error rate is high, it indicates that the signal environment is poor.

[0029] More specifically, according to the evaluation result, the system will judge the type of the current signal environment and make a decision to select a suitable working mode. The precise mode (high-sensitivity mode) is applicable when the signal environment is poor. The Bluetooth chip will use a higher receiving gain, allowing stronger signal processing and a lower bit error rate. In this mode, the Bluetooth chip will prioritize ensuring the sensitivity of signal reception and sacrifice some energy efficiency. The low-power mode (energy-saving mode) is applicable when the signal environment is good. The Bluetooth chip will reduce the receiving gain, adjust radio frequency parameters, and reduce the communication frequency if possible to reduce power consumption. In this mode, the sensitivity of signal reception will be reduced to some extent, but it can significantly extend the battery usage time. Once the signal environment changes, the system will continuously monitor the new signal environment characteristics and dynamically adjust the working mode according to the new environment characteristics.

[0030] More specifically, after the mode switch, the Bluetooth chip will continue to monitor the signal environment and feedback the communication quality in the current mode. If the signal quality does not meet the requirements in the low-power mode, the system will adjust back to the precise mode in a timely manner; conversely, if the power consumption is too high and the signal quality is poor in the precise mode, the system will switch back to the low-power mode again. By balancing and optimizing the real-time switching between the precise mode and the low-power mode, both the communication quality and the energy consumption can be ensured. Since the system dynamically switches the mode according to the real-time signal environment characteristics, it can effectively cope with the rapid changes in the signal environment. Combining multiple indicators such as signal environment characteristics, bit error rate, and signal-to-noise ratio, the system can make intelligent decisions to ensure that the Bluetooth chip is flexibly adjusted according to the actual environment. The introduction of machine learning or adaptive algorithms can further optimize the mode switching strategy and improve the accuracy of decision-making.

[0031] Specifically, in step S3 of the embodiment provided by the present invention, the signal strength received by the Bluetooth chip is monitored in real time to ensure that it meets the set standard. In the precision mode, the Bluetooth chip will increase the receiving gain (such as LNA gain) to improve the signal receiving sensitivity and ensure the reception of weaker signals. In the low-power mode, the gain is reduced to lower the power consumption and avoid excessive battery consumption. By moderately reducing the receiving gain, unnecessary energy consumption can be reduced while ensuring the maintenance of basic communication capabilities in a poor signal environment. The signal transmission is optimized by adjusting the receiving frequency band and bandwidth. In a good signal environment, the bandwidth can be expanded to increase the transmission rate; while in a low-signal environment, the bandwidth can be reduced to reduce the influence of frequency bandwidth on noise.

[0032] More specifically, by adjusting the sampling rate of the demodulator, the accuracy of data demodulation is controlled. In the precision mode, the sampling rate of the demodulator is relatively high to ensure high-precision signal demodulation. In the low-power mode, the sampling rate is appropriately reduced to reduce the power consumption. The symbol rate of demodulation is adjusted according to the signal quality. When the signal quality is poor, the symbol rate is reduced to improve the reliability of data transmission. In a poor signal quality environment, the strength of the error correction code and the complexity of the decoding algorithm are increased to compensate for the errors caused by signal interference. In the precision mode, the demodulator will adopt a more efficient error correction method to improve the demodulation accuracy.

[0033] More specifically, the Bluetooth chip continuously monitors the received signal characteristics (such as RSSI, SNR, BER, etc.) and dynamically adjusts the parameters of the radio frequency and demodulator according to this data. For example, in the case of large fluctuations in signal quality, the chip will automatically perform gain adjustment, frequency tuning or sampling rate adjustment according to the changes to keep the signal receiving sensitivity always meet the specified standard. Adaptive control algorithms (such as PID control, fuzzy control or machine learning algorithms) are used to optimize the adjustment of radio frequency and demodulator parameters. These algorithms can continuously adjust and optimize the chip working mode according to the real-time feedback to ensure the stability and reliability of communication.

[0034] It can be understood that in the precision mode, by means of increasing the gain, raising the sampling rate and symbol rate, etc., the Bluetooth chip can receive weaker signals, ensuring high-sensitivity reception. The signal receiving sensitivity always remains at the set standard, thus improving the signal receiving accuracy and communication quality. In the low-power mode, by means of reducing the receiving gain, decreasing the bandwidth, reducing the sampling rate, etc., although the receiving sensitivity is reduced, the power consumption is effectively reduced and the lowest signal receiving quality is maintained in a poor signal environment. The Bluetooth chip can quickly adapt to environmental changes by dynamically adjusting the parameters of the radio frequency and demodulator in real time. By adjusting the parameters of the demodulator in real time, especially error correction and symbol rate adjustment, the bit error rate caused by signal interference can be effectively reduced to ensure the reliable transmission of data in a poor signal quality situation.

[0035] Specifically, in step S4 of the embodiment provided by the present invention, the signal data obtained from synchronous monitoring is analyzed to identify the change trend of signal quality, and optimization is carried out according to the following principles: when the signal environment is poor, the receiving sensitivity is improved, the gain is increased or a more suitable modulation method is selected; when the signal environment is good, the power consumption is reduced by reducing the gain or the modulation accuracy to optimize the energy efficiency.

[0036] More specifically, based on machine learning or adaptive algorithms (such as PID control, fuzzy control, etc.), the optimization scheme is automatically adjusted according to the real-time changes of the signal. The optimization content includes: dynamically adjusting the receiving gain according to the signal strength (RSSI) to optimize the receiving sensitivity, selecting the most suitable communication frequency band and bandwidth according to the interference condition of the signal, dynamically adjusting the modulation method according to the signal quality to improve the bit error rate performance and maintain stable data transmission.

[0037] More specifically, the optimized scheme will be applied to the radio frequency communication part of the Bluetooth chip to adjust parameters such as gain, frequency, and bandwidth to ensure that the Bluetooth chip can flexibly respond to signal fluctuations in the real-time environment. The optimized scheme will also affect the parameter settings of the demodulator, including the sampling rate, symbol rate, error correction algorithm, etc., to ensure that the demodulator can adjust the data reception accuracy in real time according to the changing signal environment. According to the optimized scheme, the Bluetooth chip will continue to adjust the radio frequency and demodulator parameters in real time and synchronously monitor the signal effect. This adjustment is a closed-loop process, and the system continuously fine-tunes the parameters according to the latest signal quality feedback to ensure that the communication quality always meets the standard. The Bluetooth chip automatically adjusts according to the feedback signal quality information (such as RSSI, SNR, BER, etc.). This process is adaptive and can cope with dynamic changes in the environment, such as the movement of devices and the change of interference sources.

[0038] The present invention provides a method for optimizing the signal receiving sensitivity of a low-power dual-mode Bluetooth chip, which has the following beneficial effects:

[0039] The present invention monitors the signal reception environment of a Bluetooth chip to obtain signal environment characteristics, and switches the Bluetooth chip to a precision mode or a low-power mode according to the signal environment characteristics. In the precision mode or the low-power mode, according to a preset signal parameter adjustment scheme, the radio frequency communication and demodulator parameters are optimized in real time to ensure that the signal reception sensitivity meets the standard, and the signal effect of the Bluetooth chip is synchronously monitored. According to the monitoring results, the signal parameter scheme is adjusted and optimized, and the radio frequency communication and demodulator parameters are continuously adjusted. By intelligently switching the working mode and dynamically adjusting the parameters, the reception sensitivity of the Bluetooth chip in different signal environments is optimized, the power consumption is minimized in the low-power mode, and the communication quality is ensured at the same time. The real-time synchronous monitoring and adjustment ensure that the Bluetooth device maintains stable communication in various environments, solving the problem in the prior art that it is difficult for a Bluetooth chip to balance energy consumption and communication quality.

[0040] Preferably, the step of performing real-time detection on the signal reception environment of the Bluetooth chip to obtain the signal environment characteristics of the Bluetooth chip includes:

[0041] S11: Collect the signal reception intensity of the Bluetooth chip through the received signal strength indication function preset in the Bluetooth chip to obtain the signal reception intensity of the Bluetooth chip;

[0042] S12: Measure the signal power and noise power of the Bluetooth chip, and calculate the signal-to-noise ratio of the Bluetooth chip according to the signal power and noise power of the Bluetooth chip to obtain the signal reception quality of the Bluetooth chip;

[0043] S13: Monitor the bit error rate of the Bluetooth chip to obtain the bit error rate of the Bluetooth chip, and perform combined processing on the signal reception intensity, signal reception quality, and bit error rate of the Bluetooth chip to obtain the signal reception environment of the Bluetooth chip.

[0044] Specifically, the Bluetooth chip uses the built-in received signal strength indication (RSSI) function to collect the received signal strength in real time. RSSI is a value representing the received signal power, usually in dBm. The Bluetooth chip collects RSSI during each data transmission. Through these RSSI data, the current signal strength of the Bluetooth chip can be judged. The signal strength is one of the basic indicators for judging the Bluetooth communication quality. A higher signal strength usually means that the distance between devices is closer or there are no obstacles. However, insufficient signal strength will lead to problems such as poor reception quality and unstable data transmission. Therefore, by monitoring RSSI in real time, timely feedback on signal strength changes can be obtained, providing data support for subsequent quality evaluation.

[0045] More specifically, the Bluetooth chip measures the power of the transmitted signal through built-in hardware circuits or algorithms. This is usually the effective signal power received by the chip. In the absence of an effective signal, the power of the background noise is measured. The noise power usually comes from electromagnetic interference (EMI) in the surrounding environment, noise of the device itself, etc. The signal-to-noise ratio (SNR) is calculated using the formula SNR = signal power / noise power. The SNR is an important indicator for measuring the quality of the received signal. A higher SNR means better signal quality and less noise. The SNR is a key indicator for measuring signal quality: The SNR directly affects the stability and error rate of data transmission. A higher SNR usually means a relatively stronger signal and less noise interference during transmission, thus reducing the bit error rate in data transmission. By monitoring the SNR in real time, the quality of the signal environment can be accurately grasped and optimized adjustments can be made when necessary.

[0046] More specifically, the Bluetooth chip monitors the bit error situation that occurs during data transmission through a built-in demodulator. The bit error rate (BER) refers to the proportion of data bits that are in error during data transmission. The calculation of the BER is based on comparing the received data bits with the transmitted data bits. Generally, the lower the BER, the higher the reliability of data transmission. The BER is an intuitive indicator for finally evaluating the communication quality: Although the signal strength and SNR are key factors affecting communication quality, the final data transmission quality needs to be directly measured by the BER. A higher BER usually indicates poor signal quality or severe interference. Therefore, monitoring the BER in real time can help detect potential communication problems and optimize according to the bit error situation.

[0047] More specifically, a comprehensive analysis is performed on each parameter (signal reception strength, SNR, BER). Through multi-dimensional data fusion, the comprehensive quality of the current signal environment can be evaluated more accurately. The combination processing method can be selected according to the specific application scenario: Methods such as weighted average and priority sorting can be used, combined with empirical values or algorithm models, to comprehensively evaluate the signal reception environment. A single parameter (such as RSSI, SNR, or BER) is not sufficient to fully reflect the actual situation of the signal environment. For example, when the signal strength is high but the BER is high, the communication quality is still poor. Therefore, through multi-dimensional parameter combination processing, a more accurate evaluation of the signal reception environment can be obtained, so as to better perform dynamic adjustment and optimization.

[0048] Preferably, the steps of switching the working mode of the Bluetooth chip according to the signal environment characteristics to switch the Bluetooth chip to the precise mode or the low-power mode corresponding to the signal reception environment include:

[0049] S21: Make a direct threshold judgment on the signal reception environment according to the pre-deployed decision logic to determine whether the signal reception environment belongs to a type I environment, a type II environment, or an intermediate environment;

[0050] S22: When the signal reception environment belongs to the intermediate environment, perform a conformity recognition of the environmental features of the signal reception environment according to a machine learning model pre-trained for identifying the first type of environment and the second type of environment, so as to obtain the conformity index of the Bluetooth chip corresponding to the first type of environment and the second type of environment, and determine whether the signal reception environment belongs to the first type of environment or the second type of environment based on the conformity index;

[0051] S23: When the signal reception environment belongs to the first type of environment, generate a corresponding first mode switching instruction to drive the Bluetooth chip to switch to the low-power mode;

[0052] S24: When the signal reception environment belongs to the second type of environment, generate a corresponding second mode switching instruction to drive the Bluetooth chip to switch to the precision mode.

[0053] Specifically, before switching the mode of the Bluetooth chip, first classify the signal reception environment through a preset decision logic. The signal environment is judged based on features such as the received signal strength, signal-to-noise ratio, and bit error rate. By performing threshold judgment on these environmental features, it is determined whether the current signal reception environment belongs to the first type of environment (good environment), the second type of environment (poor environment), or the intermediate environment (between the two). Threshold judgment provides a fast signal environment classification method, which can quickly determine the general category of the environment and provide a basis for subsequent precise decision-making. When the signal environment is good (such as high RSSI and high SNR), it can be considered a "good environment"; while when the signal is poor (such as low signal strength and large noise interference), it is classified as a "poor environment"; and for the intermediate state between the two, a machine learning model will be further used for more precise classification.

[0054] More specifically, when the signal environment belongs to the intermediate environment, the system will call a pre-trained machine learning model (such as support vector machine, decision tree, neural network, etc.) to analyze more features of the signal environment, such as signal fluctuation trend, historical signal features, etc. The machine learning model will perform a "conformity recognition" of the features of the current environment according to the training data, and calculate the conformity index of the signal reception environment with the first type of environment or the second type of environment (such as similarity score, probability value, etc.). Through the rules obtained by training based on historical data, the machine learning model can more precisely identify the subtle features of the current signal environment, thereby making a more accurate classification judgment. Compared with traditional threshold judgment, machine learning can handle complex and fuzzy environmental changes, and is more suitable for dealing with the situation of "intermediate environment" with fuzzy boundaries. As the environmental features change, the machine learning model can adjust the decision boundary through continuous optimization and training, enabling the system to dynamically adapt to various changing environments and improve the intelligence level of the Bluetooth system.

[0055] More specifically, based on the output results of the machine learning model (conformity index), the system will decide whether the signal reception environment ultimately belongs to Class I or Class II. If the model gives a higher conformity index for Class I environment, the current environment is considered to belong to Class I environment; otherwise, it belongs to Class II environment. Through the analysis of the machine learning model, the signal reception environment can be classified more accurately to ensure that the system can make correct mode switching decisions. This enables the system to optimize the mode accordingly for different environment types (such as signal strength, interference conditions, etc.).

[0056] More specifically, once it is determined that the signal environment belongs to a Class I environment or a Class II environment, the system will generate a corresponding mode switching instruction: Class I environment: If the signal reception environment is determined to be a Class I environment (i.e., a good environment), the system will generate a first mode switching instruction to drive the Bluetooth chip to switch to a low-power mode to reduce power consumption; Class II environment: If the signal reception environment is determined to be a Class II environment (i.e., a poor environment), the system will generate a second mode switching instruction to drive the Bluetooth chip to switch to a precise mode to improve reception accuracy and anti-interference capability.

[0057] More specifically, when the environmental signal is good (such as strong signal and low noise), the Bluetooth chip can adopt a low-power working mode to reduce battery consumption and extend the use time of the device. At this time, the system has lower accuracy requirements and focuses on saving energy. When the environmental signal is poor (such as weak signal and large noise interference), it is necessary to improve the reception accuracy and stability. At this time, the Bluetooth chip needs to switch to the precision mode, which may use stronger receiving power, redundant transmission and other methods to enhance the reliability of data transmission and try to avoid bit errors and packet loss.

[0058] It is understandable that by dynamically switching to low-power mode, the Bluetooth chip can reduce power consumption when the signal environment is good and extend the battery life of the device. This method is especially important for Bluetooth devices that rely on battery power and can effectively save energy. When the signal environment is poor, switching to precise mode can improve the stability of Bluetooth communication and reduce signal attenuation, bit errors and other problems, thereby ensuring high reliability of data transmission. By combining the characteristics of the signal reception environment and the machine learning model, the Bluetooth chip can intelligently adapt to different environmental changes and automatically optimize the working mode. This adaptive capability enables Bluetooth devices to continue to provide high-quality services in various complex environments without human intervention.

[0059] Preferably, when the Bluetooth chip is in the precise mode or the low-power mode, the step of dynamically adjusting the radio frequency communication parameters and the demodulator parameters of the Bluetooth chip in real time according to the signal parameter adjustment scheme corresponding to the precise mode or the low-power mode so that the signal receiving sensitivity of the Bluetooth chip is within the specified standard includes:

[0060] S31: When the Bluetooth chip is in the precision mode, perform real-time dynamic adjustment of the radio frequency communication parameters and demodulator parameters of the Bluetooth chip according to the adaptive gain control scheme, so that the signal reception sensitivity of the Bluetooth chip is at a specified standard; wherein, the adaptive gain control scheme is a signal parameter adjustment scheme corresponding to the precision mode;

[0061] S32: When the Bluetooth chip is in the low-power mode, perform real-time dynamic adjustment of the radio frequency communication parameters and demodulator parameters of the Bluetooth chip according to the signal parameter adjustment framework, so that the signal reception sensitivity of the Bluetooth chip is at a specified standard; wherein, the signal parameter adjustment framework is a signal parameter adjustment scheme corresponding to the low-power mode.

[0062] Specifically, when the Bluetooth chip is in the precision mode, the system dynamically adjusts the radio frequency communication parameters and demodulator parameters according to the adaptive gain control scheme (AGC). The goal of the adaptive gain control scheme is to ensure that in the precision mode, the Bluetooth chip can reach the specified standard in terms of signal reception sensitivity by adjusting parameters such as the reception gain, noise filter gain, and demodulator sensitivity. Adaptive gain control will automatically detect the signal strength, interference situation, signal quality, etc., and adjust the parameters in real time to optimize the reception sensitivity to the maximum extent, thereby improving the reliability and accuracy of communication. Radio frequency communication parameters such as the reception gain and the gain of the signal amplifier, according to the signal strength in the environment, AGC will adjust these parameters in a timely manner to ensure that the signal is neither too strong nor too weak, reaching an optimal reception level. Demodulator parameters such as the accuracy of signal demodulation and filter settings. In the precision mode, the demodulator will use higher accuracy to decode the signal, ensuring a lower bit error rate and higher stability. Through adaptive gain control, the reception sensitivity can be optimized in the precision mode, reducing signal loss or incorrect decoding, thereby achieving higher-quality communication. Especially in an environment with complex signals or large interference, this adjustment is particularly important and can improve the overall stability of the system.

[0063] More specifically, when the Bluetooth chip is in the low-power mode, the system will perform real-time dynamic adjustment according to the signal parameter adjustment framework to ensure that the reception sensitivity reaches the predetermined standard while minimizing power consumption. The signal parameter adjustment framework is designed for the low-power mode and mainly focuses on reducing power consumption while ensuring the basic signal reception sensitivity. The system will automatically adjust the radio frequency communication parameters and demodulator parameters according to environmental changes to adapt to weaker signals or more relaxed communication requirements. In the low-power mode, the system usually reduces the gain, decreases the power consumption of the demodulator, and at the same time increases the tolerance for reduced sensitivity to maximize battery life.

[0064] More specifically, by appropriately reducing the receiving gain, power consumption is decreased; if the signal is strong, the system will reduce its reliance on the signal amplifier by adjustment, adjust the operating mode and computational accuracy of the demodulator, adopt a low-power demodulation algorithm or appropriately simplify the demodulation process to reduce power consumption while ensuring the basic receiving quality. The most crucial goal in the low-power mode is to reduce power consumption. Therefore, all signal processing procedures must be optimized into low-power versions. Although this will sacrifice the receiving sensitivity of the signal, the system will make intelligent adjustments to maintain a balance between power consumption and receiving sensitivity. The adjustment framework in the low-power mode can still maintain stable communication at low signal intensities, ensuring that the device can achieve reasonable connection quality while saving energy.

[0065] More specifically, the system will make dynamic adjustments in the precise mode or low-power mode by continuously monitoring the received signal quality and combining the dynamic changes in the environment (such as signal strength, noise interference, device movement, etc.). In the precise mode, the system will increase the demodulation accuracy and signal receiving gain to adapt to signal fluctuations; in the low-power mode, the system will reduce these settings to further reduce power consumption while still maintaining basic connection stability. The dynamic adjustment is driven by the feedback mechanism of the system. The Bluetooth chip adjusts the parameters in real time according to the environmental conditions and verifies whether the adjusted signal receiving sensitivity meets the standard. This process is usually achieved through continuous monitoring and feedback loops, enabling the Bluetooth chip to automatically adapt to environmental changes without manual intervention by the user.

[0066] Preferably, the steps of making real-time dynamic adjustments to the radio frequency communication parameters and demodulator parameters of the Bluetooth chip according to the adaptive gain control scheme include:

[0067] S311: Evaluate the gain requirements for the signal environment characteristics of the Bluetooth chip according to the target receiving sensitivity preset for the precise mode to obtain the initial gain value of the Bluetooth chip;

[0068] S312: Assign the task of signal receiving gain to the radio frequency communication parameters and demodulator parameters according to the initial gain value to obtain the adjustment parameters of the radio frequency communication parameters and demodulator parameters corresponding to the initial gain value;

[0069] S313: Analyze the gain responsiveness and gain stability of the adjustment parameters of the radio frequency communication parameters and the demodulator parameters to obtain the execution characteristics of the current adjustment parameters of the radio frequency communication parameters and the demodulator parameters;

[0070] S314: Based on the executive characteristics of the adjustment parameters, perform signal reception gain task weight correction on the radio frequency communication parameters and the demodulator parameters with respect to the initial gain value, and optimize the adjustment parameters for the radio frequency communication parameters and the demodulator parameters based on the corrected signal reception gain task weight;

[0071] S315: Perform real-time dynamic adjustment of the radio frequency communication parameters and the demodulator parameters of the Bluetooth chip according to the adjustment parameters, so that the signal reception sensitivity of the Bluetooth chip is at a specified standard.

[0072] Specifically, based on the target reception sensitivity in the preset precision mode, evaluate the signal environment characteristics where the current Bluetooth chip is located to determine the required gain. The signal environment characteristics may include signal strength, noise, interference, frequency offset, etc. The changes in these characteristics determine the required gain to ensure that the chip can reach the specified reception sensitivity standard in different signal environments. In the precision mode, the goal of the Bluetooth chip is to achieve a certain signal reception sensitivity, which requires adjusting the gain according to the specific signal environment. Through gain requirement evaluation, the signal characteristics of the current environment can be quantified, and combined with the target sensitivity, the initial gain value of the Bluetooth chip can be determined. This is the starting step of the entire adaptive gain control. The signal environment changes frequently. Real-time evaluation of the signal environment characteristics can provide accurate preliminary parameters for subsequent gain adjustment, ensuring that the Bluetooth chip can dynamically adapt to environmental changes.

[0073] More specifically, based on the initial gain value, allocate the signal reception gain task to the radio frequency communication parameters and the demodulator parameters. Specifically, the radio frequency communication parameters (such as gain control, filter gain, etc.) and the demodulator parameters (such as demodulation accuracy, sensitivity setting, etc.) will be assigned different tasks according to the initial gain value, generating preliminary adjustment parameters. The radio frequency communication part and the demodulator part respectively undertake different gain tasks. Reasonable task allocation can avoid over-reliance on a certain part, thereby ensuring that the overall performance of the system is optimized. Through task allocation, it can be ensured that the adjustment tasks of each component are highly targeted and specific. This step can effectively avoid over-gain adjustment or imbalance caused by uneven resource allocation or task overlap.

[0074] More specifically, the adjustment parameters of the obtained radio frequency communication parameters and demodulator parameters are analyzed to evaluate their gain responsiveness and gain steady-state performance. Responsiveness refers to the ability of the system to quickly respond to gain changes, and steady-state performance refers to the ability of the system to maintain stability after reaching the gain target. The Bluetooth chip needs to be able to quickly adapt to environmental changes, especially in scenarios with large fluctuations in signal quality. By analyzing the responsiveness, it can be ensured that the gain adjustment can respond quickly, reducing the instability of signal reception. By evaluating the steady-state performance, it is ensured that after the gain adjustment, the system can maintain stable signal reception performance, avoiding performance instability or communication interruption caused by frequent changes.

[0075] More specifically, according to the analysis results of the gain responsiveness and steady-state performance, the signal reception gain task weights of the radio frequency communication parameters and demodulator parameters are corrected. This means that according to the reaction ability and stability of the system to gain changes, the strategy of gain allocation is optimized. It may adjust the weights of certain parameters to balance the efficiency and accuracy of gain adjustment. The weight correction of signal reception gain can readjust the parameters according to the actual execution situation, ensuring that the system can work in the optimal way in the actual environment. In practical applications, the requirements for responsiveness and steady-state performance are different in different signal environments. By correcting the weights, the dynamic adaptation ability of the system can be optimized, ensuring that the gain can be adjusted efficiently and stably in different signal environments, avoiding excessive or insufficient gain settings.

[0076] More specifically, based on the corrected gain task weights, the radio frequency communication parameters and demodulator parameters are optimized and real-time dynamic adjustment is performed. At this time, the system has adjusted the gain allocation according to the actual environment and feedback, and optimized the gain control strategy. Finally, the system will update these parameters in real time to ensure that the signal reception sensitivity of the Bluetooth chip always remains at a predetermined standard. The system can continuously adjust according to real-time environmental changes, ensuring that the Bluetooth chip always provides the best signal reception sensitivity in different usage scenarios. Through real-time dynamic adjustment, the system can quickly respond when the signal environment changes, ensuring the stability and efficiency of Bluetooth communication, especially in complex or unstable environments, such as high-interference areas or low-signal-strength areas. The ultimate goal of the final adjustment is to make the reception sensitivity of the Bluetooth chip reach the preset standard. This step ensures a high-quality communication experience for Bluetooth devices.

[0077] Preferably, the steps of performing real-time dynamic adjustment of the radio frequency communication parameters and demodulator parameters of the Bluetooth chip according to the signal parameter adjustment framework include:

[0078] S321: Retrieve the signal parameter adjustment template with the first priority order based on the signal parameter adjustment framework, and perform parameter adjustment on the radio frequency communication parameters and demodulator parameters of the Bluetooth chip according to the signal parameter adjustment template;

[0079] S322: Obtain the signal reception sensitivity of the Bluetooth chip, and judge the signal reception sensitivity according to a preset threshold. If the signal reception sensitivity corresponding to the current signal parameter adjustment template does not meet the preset threshold, then, according to the difference between the signal reception sensitivity and the preset threshold, retrieve and execute a number of signal parameter adjustment templates in the second priority order for the signal parameter adjustment framework, and repeat the above steps until the signal reception sensitivity meets the preset threshold.

[0080] Specifically, based on the signal parameter adjustment framework, first retrieve the signal parameter adjustment template with the highest priority (the first priority order). According to this template, the radio frequency communication parameters and demodulator parameters of the Bluetooth chip will be adjusted. Specific parameter adjustments may involve radio frequency gain, filter settings, the sensitivity of the demodulator, etc. The signal parameter adjustment framework guides parameter adjustment through preset templates. The templatized management method can enable different signal environments to have different adjustment strategies, thereby improving the adaptability and execution efficiency of the system in different environments. Retrieving the signal parameter adjustment template of the first priority order first is because this step involves the preliminary adjustment of the optimal parameters, aiming to quickly set the parameters of the chip and conduct a preliminary optimization of the signal reception sensitivity.

[0081] More specifically, obtain the current signal reception sensitivity of the Bluetooth chip, which is usually measured through the chip's reception module, demodulation module or feedback from other systems, and judge whether the current signal reception sensitivity meets the preset threshold. For example, if the set goal is that the minimum reception sensitivity reaches a certain level (such as a certain dBm value), the system will make a comparison to judge whether it meets the standard. Obtaining and judging whether the signal reception sensitivity meets the preset threshold aims to ensure that the Bluetooth chip can stably receive effective signals in different environments. If the reception sensitivity does not meet the standard, further parameter adjustment is required to improve the reception performance. By comparing with the preset threshold, the lower limit of the signal quality can be precisely controlled to ensure that the system will not affect the communication performance due to too weak signals or poor signal quality.

[0082] More specifically, if the signal reception sensitivity still fails to reach the preset threshold after the execution of the signal parameter adjustment template of the first priority order, the system will, according to the difference between the sensitivity and the preset threshold, retrieve the signal parameter adjustment template of the second priority order and execute the template of the second priority order, which may adjust more radio frequency parameters, gains, filter settings, demodulator thresholds, etc. The purpose is to further optimize the signal reception sensitivity. When the signal reception sensitivity fails to meet the standard, the system will adopt a step-by-step optimization method for adjustment. The signal parameter adjustment template of the second priority order may adjust more in-depth parameters or make stronger adjustments for specific environmental conditions. Step-by-step adjustment can avoid over-adjustment or system instability caused by over-optimization. The template of the second priority order may include more detailed adjustments for specific signal environments, such as adjusting certain demodulation parameters or increasing signal amplification, etc., which ensures that the system can achieve sensitivity optimization under different signal conditions.

[0083] More specifically, if the adjustment of the second priority order still fails to reach the preset signal reception sensitivity, the system will continue to make more adjustments according to the preset rules, and may retrieve the signal parameter adjustment template of a lower priority and repeat the above-mentioned adjustment process. After each adjustment, the system will detect the signal reception sensitivity again and determine whether it meets the preset threshold. If it still fails to meet the standard, the subsequent steps will continue to be executed until the signal reception sensitivity meets the requirements. By continuously adjusting until the standard is reached, the system has a high degree of self-adaptability and can find the best parameter configuration in complex and changing signal environments. This process ensures that even if the initial settings fail to meet the requirements, the system can still achieve the goal through continuous adjustment. The process of repeated adjustment enables the system to optimize the reception sensitivity from multiple perspectives and gradually find the most suitable parameter configuration, thereby improving the stability and reliability of the system.

[0084] More specifically, when the signal reception sensitivity reaches the preset standard, the system confirms that all adjustments are completed and locks the final radio frequency communication parameters and demodulator parameter settings. These final parameters will be maintained and used for actual signal reception during subsequent Bluetooth communication. Confirming the final parameter settings can ensure that the system stably meets the reception sensitivity standard during actual use. Through a series of dynamic adjustments, the system can maintain good communication quality in different signal environments.

[0085] Preferably, the steps of synchronously monitoring the signal effect of the Bluetooth chip, adjusting and optimizing the signal parameter adjustment scheme according to the results of the synchronous monitoring, and continuously performing real-time dynamic adjustment of the radio frequency communication parameters and demodulator parameters of the Bluetooth chip through the adjusted and optimized signal parameter adjustment scheme include:

[0086] S41: Record the signals received by the Bluetooth chip to obtain the received signal sequence of the Bluetooth chip;

[0087] S42: Analyze the signal-to-noise ratio, bit error rate, and modulation error ratio of the radio frequency communication parameters and demodulator parameters of the Bluetooth chip at the current moment according to the received signal sequence, so as to obtain the signal effect synchronization monitoring characteristics of the radio frequency communication parameters and demodulator parameters of the Bluetooth chip at the current moment;

[0088] S43: When the Bluetooth chip is in the low-power mode and the signal effect synchronization monitoring characteristics indicate that the signal reception sensitivity of the Bluetooth chip does not meet the specified standard, drive the Bluetooth chip to switch to the precision mode and execute the signal parameter adjustment scheme corresponding to the precision mode;

[0089] S44: When the Bluetooth chip is in the precision mode and the signal effect synchronization monitoring characteristics indicate that the signal reception sensitivity of the Bluetooth chip does not meet the specified standard, drive the Bluetooth chip to switch to the full-power adjustment mode;

[0090] S45: The Bluetooth chip in the full-power adjustment mode performs parameter deployment with the highest power on the radio frequency communication parameters and demodulator parameters, and gradually performs execution tests on the downward adjustment of the radio frequency communication parameters and demodulator parameters until the radio frequency communication parameters and demodulator parameters with the signal reception sensitivity of the Bluetooth chip meeting the specified standard are obtained.

[0091] Specifically, record the signals received by the Bluetooth chip in real time to generate a received signal sequence. Recording the received signal sequence is the basis for subsequent signal analysis. By collecting signal data, the system can effectively reflect the changes in signals in the current communication environment. These signal sequences provide raw data for subsequent analyses such as signal-to-noise ratio (SNR), bit error rate (BER), and modulation error ratio (MER).

[0092] More specifically, according to the recorded received signal sequence, analyze the signal effect of the Bluetooth chip at the current moment, including: Signal-to-noise ratio (SNR): Evaluate the ratio of the signal to the noise, reflecting the signal quality; Bit error rate (BER): Detect the number of incorrect bits through the received bit stream to evaluate the decoding quality; Modulation error ratio (MER): Measure the error of the modulated signal, reflecting the accuracy of the modulation and demodulation process. These parameters are the key indicators for measuring the signal quality of the Bluetooth chip. By analyzing these parameters, the current communication status can be understood in real time, providing a basis for subsequent parameter adjustment. Taking these signal characteristics as the core content of synchronous monitoring can help monitor the performance of the Bluetooth chip in different working environments in real time and ensure that the communication quality meets the standards.

[0093] More specifically, when the system detects that the Bluetooth chip is in the low-power mode and the signal reception sensitivity does not meet the predetermined standard (the signal quality is detected as not meeting the standard through synchronous monitoring of characteristics), the system will drive the Bluetooth chip to switch to the precision mode. After switching to the precision mode, the corresponding signal parameter adjustment scheme will be executed to improve the signal quality. When the Bluetooth chip has switched to the precision mode but the signal effect still does not meet the standard, the system will drive the chip to switch to the full-power adjustment mode. Switching between low power and precision modes: The low-power mode is usually used when the Bluetooth device is in standby or has a low data transfer volume, and the communication requirements are relatively low at this time. The precision mode is the working mode when the communication quality requirements are relatively high and can perform more detailed signal optimization. When the signal reception sensitivity does not meet the standard, switching to the precision mode can increase the reception performance.

[0094] More specifically, when the signal standard is still not met in the precision mode, switching to the full-power mode can ensure that the reception sensitivity meets the requirements by increasing the radio frequency power. The full-power mode provides the strongest signal output ability for the system, but at this time, the system will gradually adjust the parameters of radio frequency communication and the demodulator to reduce the power output and avoid unnecessary power consumption. In the full-power adjustment mode, the Bluetooth chip will first set the radio frequency communication parameters and the demodulator parameters to the highest power to ensure that the signal reception sensitivity is maximally improved. Then, the system gradually reduces the power of the radio frequency communication parameters and the demodulator parameters and performs a step-by-step downward test. After each reduction, the system will detect the signal effect (such as reception sensitivity) and determine whether it meets the predetermined standard. If at a certain stage, the signal reception sensitivity meets the standard, the current radio frequency communication and demodulator parameters will be locked; in the full-power mode, by first setting to the highest power, it ensures that the system can obtain strong signal support in the worst signal environment, which provides a basis for subsequent parameter optimization and adjustment. Gradually reducing the power is to find the best parameter settings that can still maintain good signal reception sensitivity without consuming too much battery resources. Through step-by-step testing, it can effectively avoid excessive power consumption caused by over-adjustment and save energy on the premise of ensuring communication quality. After multiple adjustments and tests, the Bluetooth chip will finally obtain a set of radio frequency communication parameters and demodulator parameters that meet the signal reception sensitivity standard, and these parameters will be used as the final configuration and applied to the daily communication process.

[0095] It can be understood that through this step-by-step adjustment process, the system can not only find the best radio frequency communication parameters and demodulator parameters but also ensure the stability and high performance of the system in different signal environments. This ensures that the Bluetooth communication quality can meet the requirements in various application scenarios. By gradually reducing the power, the system can achieve the goal of low power consumption while ensuring communication quality, maximizing the energy efficiency of the system.
