DETAILED DESCRIPTION

[0008] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with 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 intended to limit the present invention.

[0009] The implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0010] Reference Figure 1 , Figure 2 As shown, a preferred embodiment of the present invention is provided.

[0011] In a first aspect, the present invention provides a method for optimizing the signal receiving sensitivity of a low-power dual-mode Bluetooth chip, comprising: S1: Perform real-time detection on the signal receiving environment of the Bluetooth chip to obtain the signal environment characteristics of the Bluetooth chip; S2: Switching the working mode of the Bluetooth chip according to the signal environment characteristics, so as to switch the Bluetooth chip to a precise mode or a low-power mode corresponding to the signal receiving environment; S3: when the Bluetooth chip is in the precise mode or the low-power mode, dynamically adjust the radio frequency communication parameters and 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; S4: synchronously monitor the signal effect of the Bluetooth chip, adjust and optimize the signal parameter adjustment scheme according to the result of the synchronous monitoring, and continue to dynamically adjust the RF communication parameters and demodulator parameters of the Bluetooth chip in real time by adjusting the optimized signal parameter adjustment scheme.

[0012] Specifically, in step S1 of the embodiment provided by the present invention, the received signal strength indicator (RSSI) built into the Bluetooth chip is used to collect the current received signal strength in real time. This function can reflect the strength of the signal in the current environment and help determine the basic situation of the signal quality. The signal power (Signal Power) and noise power (Noise Power) received by the Bluetooth chip are measured. 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 the subsequent signal-to-noise ratio (SNR) calculation. Based on the values ​​of the signal power and the 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 have greater interference. The bit error rate (BER) is monitored, that is, the ratio of errors when receiving data. 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 the receiving process needs to be adjusted.

[0013] More specifically, the signal strength, signal-to-noise ratio, bit error rate and other information are comprehensively analyzed to obtain the signal reception environment characteristics of the Bluetooth chip. Through the combined processing of 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. Through comprehensive analysis of signal environment characteristics, the Bluetooth chip can dynamically adjust the working mode (such as precision mode or low-power mode) according to actual conditions, thereby ensuring that good performance can be maintained in different environments. Accurate detection and analysis of the signal environment helps to optimize the signal reception capability of the Bluetooth chip. For example, if the signal-to-noise ratio is low, the system can adjust the parameters to improve the receiving sensitivity; if the bit error rate is high, the system can make appropriate gain adjustments or switch working modes to reduce errors. Through comprehensive analysis of signal quality, it can respond in a timely manner in an environment with poor signal quality, reduce the bit error rate, and improve 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 optimal performance and energy efficiency under different environmental conditions.

[0014] Specifically, in step S2 of the embodiment provided by the present invention, the Bluetooth chip acquires signal environment characteristics in real time, 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 (ie, signal interference is small), and the bit error rate is low, it means that the signal environment is good. If the signal strength is weak, the signal-to-noise ratio is low (ie, the noise is strong), and the bit error rate is high, it means that the signal environment is poor.

[0015] More specifically, based on the evaluation results, the system will determine the type of the current signal environment and make a decision to select the appropriate working mode. The precision mode (high sensitivity mode) is suitable for situations where 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 the sensitivity of signal reception and sacrifice some energy efficiency. The low-consumption mode (energy-saving mode) is suitable for situations where the signal environment is good. The Bluetooth chip will reduce the receiving gain, adjust the RF parameters, and reduce the communication frequency when possible to reduce power consumption. In this mode, the sensitivity of signal reception will be reduced, but the battery life can be significantly extended. 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 environmental characteristics.

[0016] More specifically, after the mode is switched, the Bluetooth chip will continue to monitor the signal environment and provide feedback on 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. The balance optimization of real-time switching between the precise mode and the low-power mode can not only ensure the communication quality, but also reduce energy consumption. Since the system dynamically switches modes according to the real-time signal environment characteristics, it can effectively respond to the rapid changes in the signal environment. Combining multiple indicators such as signal environment characteristics, bit error rate, signal-to-noise ratio, etc., 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 also further optimize the mode switching strategy and improve the accuracy of decision-making.

[0017] 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 standards. In the precise mode, the Bluetooth chip will increase the receiving gain (such as LNA gain) to improve the receiving sensitivity of the signal and ensure that weaker signals are received. In the low-power mode, the gain is reduced to reduce power consumption and avoid excessive battery consumption. By moderately reducing the receiving gain, unnecessary energy consumption can be reduced while ensuring that basic communication capabilities can be maintained when the signal environment is poor. The signal transmission is optimized by adjusting the receiving frequency band and bandwidth. In an environment with a good signal, the bandwidth can be expanded to increase the transmission rate; in a low-signal environment, the bandwidth can be reduced to reduce the impact of the frequency bandwidth on noise.

[0018] More specifically, the accuracy of data demodulation is controlled by adjusting the sampling rate of the demodulator. In the precise mode, the sampling rate of the demodulator is high to ensure high-precision signal demodulation. In the low-power mode, the sampling rate will be appropriately reduced to reduce power consumption. The rate of demodulated symbols is adjusted according to the quality of the signal. When the signal quality is poor, the symbol rate is reduced to improve the reliability of data transmission. In an environment with poor signal quality, the strength of the error correction code and the complexity of the decoding algorithm are increased to compensate for errors caused by signal interference. In the precise mode, the demodulator will adopt a more efficient error correction method to improve the demodulation accuracy.

[0019] More specifically, the Bluetooth chip continuously monitors the characteristics of the received signal (such as RSSI, SNR, BER, etc.) and dynamically adjusts the parameters of the RF and demodulator based on these data. For example, when the signal quality fluctuates greatly, the chip will automatically adjust the gain, frequency tuning or sampling rate according to the changes to keep the signal reception sensitivity always in line with the specified standards. Adaptive control algorithms (such as PID control, fuzzy control or machine learning algorithms) are used to optimize the adjustment of RF and demodulator parameters. These algorithms can continuously adjust and optimize the chip operating mode based on real-time feedback to ensure the stability and reliability of communication.

[0020] It is understandable that in the precision mode, by increasing the gain, improving the sampling rate and symbol rate, the Bluetooth chip can receive weaker signals and ensure high-sensitivity reception. The signal reception sensitivity is always maintained at the set standard, thereby improving the signal reception accuracy and communication quality. In the low-power mode, by reducing the receiving gain, reducing the bandwidth, reducing the sampling rate and other means, although the receiving sensitivity is reduced, the power consumption is effectively reduced, and the minimum signal reception quality is maintained in an environment with poor signal. The Bluetooth chip can quickly adapt to environmental changes by dynamically adjusting the RF and demodulator parameters in real time. By adjusting the demodulator parameters in real time, especially the error correction and symbol rate adjustment, the bit error rate caused by signal interference can be effectively reduced, ensuring reliable data transmission under poor signal quality.

[0021] Specifically, in step S4 of the embodiment provided by the present invention, the signal data obtained by synchronous monitoring is analyzed, the changing trend of the signal quality is identified, and optimization is performed 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, and the energy efficiency is optimized by reducing the gain or reducing the modulation accuracy.

[0022] More specifically, based on machine learning or adaptive algorithms (such as PID control, fuzzy control, etc.), the optimization plan 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), optimizing the receiving sensitivity, selecting the most suitable communication frequency band and bandwidth according to the interference conditions of the signal, and dynamically adjusting the modulation method according to the signal quality to improve the bit error rate performance and maintain stable data transmission.

[0023] More specifically, the optimized solution will be applied to the RF 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 a real-time environment. The optimization solution will also affect the parameter settings of the demodulator, including sampling rate, symbol rate, error correction algorithm, etc., to ensure that the demodulator can adjust the accuracy of data reception in real time according to the changing signal environment. According to the optimized solution, the Bluetooth chip will continue to adjust the RF and demodulator parameters in real time and monitor the signal effect simultaneously. This adjustment is a closed-loop process. The system continuously fine-tunes parameters based on the latest signal quality feedback to ensure that the communication quality always meets the standards. The Bluetooth chip automatically adjusts based on the feedback signal quality information (such as RSSI, SNR, BER, etc.). This process is adaptive and can respond to dynamic changes in the environment, such as device movement, changes in interference sources, etc.

[0024] 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: The present invention monitors the signal receiving environment of the Bluetooth chip to obtain the signal environment characteristics, and switches the Bluetooth chip to the precise mode or the low-power mode according to the signal environment characteristics. In the precise mode or the low-power mode, according to the preset signal parameter adjustment scheme, the radio frequency communication and demodulator parameters are optimized in real time to ensure that the signal receiving sensitivity meets the standard, the signal effect of the Bluetooth chip is synchronously monitored, the signal parameter scheme is adjusted and optimized according to the monitoring results, and the radio frequency communication and demodulator parameters are continuously adjusted. By intelligently switching the working mode and dynamically adjusting the parameters, the receiving 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, which solves the problem that the Bluetooth chip in the prior art is difficult to balance energy consumption and communication quality.

[0025] Preferably, the step of performing real-time detection on the signal receiving environment of the Bluetooth chip to obtain the signal environment characteristics of the Bluetooth chip includes: S11: collecting the signal reception strength of the Bluetooth chip through a received signal strength indication function preset by the Bluetooth chip to obtain the signal reception strength of the Bluetooth chip; S12: measuring the signal power and the noise power of the Bluetooth chip, and calculating the signal-to-noise ratio of the Bluetooth chip according to the signal power and the noise power of the Bluetooth chip to obtain the signal reception quality of the Bluetooth chip; S13: monitoring the bit error rate of the Bluetooth chip to obtain the bit error rate of the Bluetooth chip, and combining the signal reception strength, signal reception quality and bit error rate of the Bluetooth chip to obtain the signal reception environment of the Bluetooth chip.

[0026] Specifically, the Bluetooth chip collects the received signal strength in real time through the built-in received signal strength indication (RSSI) function. RSSI is a numerical value that represents the received signal power, usually in dBm. The Bluetooth chip collects RSSI every time data is transmitted. Through these RSSI data, the current signal strength of the Bluetooth chip can be determined. Signal strength is one of the basic indicators for judging the quality of Bluetooth communication. Higher signal strength usually means that the distance between devices is closer or there are no obstacles, but insufficient signal strength will lead to poor reception quality, unstable data transmission and other problems. Therefore, by real-time monitoring of RSSI, timely feedback on changes in signal strength can be obtained, providing data support for subsequent quality evaluation.

[0027] More specifically, the Bluetooth chip measures the power of the transmitted signal through a built-in hardware circuit or algorithm. 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 the electromagnetic interference (EMI) of the surrounding environment, the noise of the device itself, etc. The formula SNR = signal power / noise power is used to calculate the signal-to-noise ratio. The signal-to-noise ratio is an important indicator for measuring the quality of the received signal. A higher SNR means better signal quality and less noise. The signal-to-noise ratio is a key indicator for measuring signal quality: the signal-to-noise ratio (SNR) directly affects the stability and error rate of data transmission. A higher signal-to-noise ratio usually means that the signal is relatively strong and the noise interference is small during transmission, thereby 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 and adjusted when necessary.

[0028] More specifically, the Bluetooth chip monitors the bit errors that occur during data transmission through a built-in demodulator. The bit error rate (BER) refers to the proportion of data bits that have errors during data transmission. The calculation of the bit error rate is based on the comparison of the received data bits with the sent data bits. Generally, the lower the BER, the higher the reliability of data transmission. The bit error rate is an intuitive indicator for the final evaluation of communication quality: although signal strength and signal-to-noise ratio are key factors affecting communication quality, the final data transmission quality needs to be directly measured by the bit error rate. A higher bit error rate usually indicates poor signal quality or severe interference. Therefore, real-time monitoring of BER can help discover potential communication problems and optimize according to the bit error situation.

[0029] More specifically, each parameter (signal reception strength, signal-to-noise ratio, bit error rate) is comprehensively analyzed. Through multi-dimensional data fusion, the comprehensive quality of the current signal environment can be more accurately evaluated. The combined processing method can be selected according to the specific application scenario: weighted average, priority sorting and other methods 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 enough to fully reflect the actual situation of the signal environment. For example, when the signal strength is high but the bit error rate 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.

[0030] Preferably, the step of switching the working mode of the Bluetooth chip according to the signal environment characteristics to switch the Bluetooth chip to a precise mode or a low-power mode corresponding to the signal receiving environment includes: S21: performing a direct threshold judgment on the signal receiving environment according to a pre-deployed decision logic to determine whether the signal receiving environment belongs to a Class I environment, a Class II environment, or an intermediate environment; S22: When the signal receiving environment belongs to the intermediate environment, the conformity of the environmental characteristics of the signal receiving environment is identified according to a machine learning model pre-trained for identifying the first and second environments, so as to obtain a conformity index of the Bluetooth chip corresponding to the first and second environments, and determine whether the signal receiving environment belongs to the first or second environment based on the conformity index; S23: When the signal receiving environment belongs to a type of environment, a corresponding first mode switching instruction is generated to drive the Bluetooth chip to switch to a low-power mode; S24: When the signal receiving environment belongs to the second type of environment, a corresponding second mode switching instruction is generated to drive the Bluetooth chip to switch to the precision mode.

[0031] Specifically, before switching the Bluetooth chip mode, the signal reception environment is first classified through the preset decision logic. The signal environment is judged based on the received signal strength, signal-to-noise ratio, bit error rate and other characteristics. By performing threshold judgment on these environmental characteristics, it is determined whether the current signal reception environment belongs to Class I environment (good environment), Class II environment (poor environment) or intermediate environment (between the two). The threshold judgment provides a fast signal environment classification method, which can quickly determine the approximate category of the environment and provide a basis for subsequent accurate decision-making. When the signal environment is good (such as high RSSI and high SNR), it can be considered as a "good environment"; when the signal is poor (such as low signal strength and large noise interference), it is classified as a "poor environment"; and the intermediate state between the two will be further classified more accurately using a machine learning model.

[0032] 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 characteristics of the signal environment, such as signal fluctuation trend, historical signal characteristics, etc. The machine learning model will perform "conformity identification" on the characteristics of the current environment based on the training data, and calculate the conformity index (such as similarity score, probability value, etc.) between the signal receiving environment and the first or second environment. The machine learning model can more accurately identify the subtle characteristics of the current signal environment based on the rules obtained through training based on historical data, thereby making more accurate classification judgments. Compared with traditional threshold judgments, machine learning can handle complex and ambiguous environmental changes and is more suitable for handling "intermediate environments" with blurred boundaries. As environmental characteristics change, the machine learning model can adjust the decision boundary through continuous optimization and training, so that the system can dynamically adapt to various changing environments and improve the intelligence level of the Bluetooth system.

[0033] 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.).

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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: S31: when the Bluetooth chip is in the precision mode, the RF communication parameters and demodulator parameters of the Bluetooth chip are adjusted dynamically in real time according to the adaptive gain control scheme, so that the signal receiving sensitivity of the Bluetooth chip is within the specified standard; wherein the adaptive gain control scheme is a signal parameter adjustment scheme corresponding to the precision mode; S32: When the Bluetooth chip is in the low-power mode, the radio frequency communication parameters and demodulator parameters of the Bluetooth chip are adjusted dynamically in real time according to the signal parameter adjustment framework, so that the signal receiving sensitivity of the Bluetooth chip is within the specified standard; wherein the signal parameter adjustment framework is a signal parameter adjustment scheme corresponding to the low-power mode.

[0038] Specifically, when the Bluetooth chip is in precise mode, the system dynamically adjusts the RF 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 the Bluetooth chip can reach the specified standard in signal reception sensitivity in precise mode by adjusting parameters such as receiving gain, noise filter gain, and demodulator sensitivity. Adaptive gain control will automatically detect signal strength, interference, signal quality, etc., and adjust parameters in real time to optimize the receiving sensitivity to the maximum, thereby improving the reliability and accuracy of communication. RF communication parameters such as receiving gain and signal amplifier gain, etc., according to the signal strength in the environment, AGC will adjust these parameters in time to ensure that the signal is not too strong or too weak and achieve an optimal reception level. Demodulator parameters such as signal demodulation accuracy and filter settings, in precise mode, the demodulator will use higher accuracy to decode the signal to ensure a lower bit error rate and higher stability. Through adaptive gain control, the receiving sensitivity can be optimized in precise mode, reducing signal loss or erroneous decoding, thereby achieving higher quality communication. This adjustment is particularly important in environments with complex signals or large interference, and can improve the overall stability of the system.

[0039] More specifically, when the Bluetooth chip is in low-power mode, the system will make real-time dynamic adjustments based on the signal parameter adjustment framework to ensure that the receiving sensitivity meets the predetermined standards while maximizing power consumption. The signal parameter adjustment framework is designed for low-power mode, focusing mainly on reducing power consumption while ensuring basic signal receiving sensitivity. The system will automatically adjust the RF communication parameters and demodulator parameters according to environmental changes to adapt to weaker signals or looser communication requirements. In low-power mode, the system will typically reduce gain and demodulator power consumption while increasing tolerance for reduced sensitivity to maximize battery life.

[0040] More specifically, power consumption is reduced by appropriately reducing the receiving gain; if the signal is strong, the system will reduce its reliance on the signal amplifier through adjustments, adjust the working mode and calculation accuracy of the demodulator, adopt a low-power demodulation algorithm or appropriately simplify the demodulation process, and reduce power consumption while ensuring basic reception quality. The most critical goal in low-power mode is to reduce power consumption, so all signal processing processes must be optimized to low-power versions. Although this will sacrifice the signal reception sensitivity, the system will intelligently adjust to maintain a balance between power consumption and reception sensitivity. The adjustment framework in low-power mode can maintain stable communication at low signal strength, ensuring that the device can achieve reasonable connection quality while saving energy.

[0041] More specifically, the system will monitor the quality of the received signal in real time and make dynamic adjustments in the precision mode or low-power mode in combination with dynamic changes in the environment (such as signal strength, noise interference, device movement, etc.). In the precision mode, the system will increase the demodulation accuracy and signal reception gain to adapt to signal fluctuations; in the low-power mode, the system will reduce these settings to further reduce power consumption while maintaining basic connection stability. The dynamic adjustment is driven by the system's feedback mechanism. The Bluetooth chip adjusts parameters in real time according to environmental conditions and verifies whether the standards are met based on the adjusted signal reception sensitivity. This process is usually achieved through continuous monitoring and feedback loops, allowing the Bluetooth chip to automatically adapt to environmental changes without manual user intervention.

[0042] Preferably, the step of dynamically adjusting the radio frequency communication parameters and demodulator parameters of the Bluetooth chip in real time according to the adaptive gain control scheme comprises: S311: performing a gain requirement evaluation on the signal environment characteristics of the Bluetooth chip according to a preset target receiving sensitivity corresponding to the precise mode, so as to obtain an initial gain value of the Bluetooth chip; S312: performing signal receiving gain task allocation for the radio frequency communication parameters and the demodulator parameters according to the initial gain value, so as to obtain adjustment parameters of the radio frequency communication parameters and the demodulator parameters corresponding to the initial gain value; 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 executable characteristics of the current adjustment parameters of the radio frequency communication parameters and the demodulator parameters; S314: modifying the signal reception gain task weights of the RF communication parameters and the demodulator parameters relative to the initial gain value according to the executable characteristics of the adjustment parameters, and optimizing the adjustment parameters of the RF communication parameters and the demodulator parameters based on the modified signal reception gain task weights; S315: Performing real-time dynamic adjustment of radio frequency communication parameters and demodulator parameters of the Bluetooth chip according to the adjustment parameters, so that the signal receiving sensitivity of the Bluetooth chip is within a specified standard.

[0043] Specifically, according to the target receiving sensitivity in the preset precise mode, the signal environment characteristics of the current Bluetooth chip are evaluated 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 meet the specified receiving sensitivity standards in different signal environments. In precise mode, the goal of the Bluetooth chip is to achieve a certain signal receiving sensitivity, which requires adjusting the gain according to the specific signal environment. Through gain demand 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 signal environment characteristics can provide accurate preliminary parameters for subsequent gain adjustments, ensuring that the Bluetooth chip can dynamically adapt to environmental changes.

[0044] More specifically, according to the initial gain value, the signal reception gain task is assigned to the RF communication parameters and the demodulator parameters. Specifically, the RF 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 to generate preliminary adjustment parameters. The RF 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 system is optimized in terms of overall performance. Through task allocation, it can be ensured that the adjustment task of each component is highly targeted and specific. This step can effectively avoid excessive gain adjustment or imbalance caused by uneven resource allocation or task overlap.

[0045] More specifically, the obtained adjustment parameters of the RF communication parameters and demodulator parameters are analyzed to evaluate their gain responsiveness and gain stability. Responsiveness refers to the system's ability to respond quickly to gain changes, and stability refers to the system's ability to maintain stability after reaching the gain target. The Bluetooth chip needs to be able to quickly adapt to environmental changes, especially in scenarios where the signal quality fluctuates greatly. By analyzing the responsiveness, it can be ensured that the gain adjustment can respond quickly to reduce the instability of signal reception. By evaluating the stability, it can be ensured that after the gain adjustment, the system can maintain stable signal reception performance to avoid unstable performance or communication interruptions due to frequent changes.

[0046] More specifically, based on the analysis results of gain responsiveness and stability, the signal reception gain task weights are corrected for the RF communication parameters and demodulator parameters. This means that the gain allocation strategy is optimized based on the system's responsiveness and stability to gain changes, and the weights of certain parameters may be adjusted to balance the efficiency and accuracy of gain adjustment. The weight correction of the signal reception gain can readjust the parameters according to the actual execution situation to ensure that the system can work in the best manner under the actual environment. In actual applications, the responsiveness and stability requirements under different signal environments are different. By correcting the weights, the dynamic adaptability of the system can be optimized to ensure that the gain can be adjusted efficiently and stably under different signal environments to avoid excessive or insufficient gain settings.

[0047] More specifically, based on the corrected gain task weights, the RF communication parameters and demodulator parameters are optimized and real-time dynamic adjustments are performed. At this point, the system has adjusted the gain distribution according to the actual environment and feedback, and optimized the gain control strategy. Ultimately, the system will update these parameters in real time to ensure that the signal reception sensitivity of the Bluetooth chip is always within the predetermined standard. The system can continuously adjust according to real-time environmental changes to ensure that the Bluetooth chip always provides the best signal reception sensitivity in different usage scenarios. Through real-time dynamic adjustments, the system can respond quickly when the signal environment changes, ensuring the stability and efficiency of Bluetooth communications, especially in complex or unstable environments, such as high interference areas or low signal strength areas. The ultimate adjustment goal is to make the receiving sensitivity of the Bluetooth chip reach the preset standard. This step ensures a high-quality communication experience for Bluetooth devices.

[0048] Preferably, the step of dynamically adjusting the radio frequency communication parameters and demodulator parameters of the Bluetooth chip in real time according to the signal parameter adjustment framework includes: S321: Retrieving a signal parameter adjustment template of a first priority order based on the signal parameter adjustment framework, and performing parameter adjustment of radio frequency communication parameters and demodulator parameters of the Bluetooth chip according to the signal parameter adjustment template; S322: Obtain the signal receiving sensitivity of the Bluetooth chip, and judge the signal receiving sensitivity according to a preset threshold; if the signal receiving sensitivity corresponding to the current signal parameter adjustment template does not meet the preset threshold, retrieve and execute several signal parameter adjustment templates of the second priority order of the signal parameter adjustment framework according to the difference between the signal receiving sensitivity and the preset threshold, and repeat the above steps until the signal receiving sensitivity meets the preset threshold.

[0049] Specifically, based on the signal parameter adjustment framework, the signal parameter adjustment template with the highest priority (first priority) is first called. According to the template, the RF communication parameters and demodulator parameters of the Bluetooth chip will be adjusted. The specific parameter adjustment may involve RF gain, filter settings, demodulator sensitivity, etc. The signal parameter adjustment framework guides the parameter adjustment through preset templates. The templated management method can make different signal environments correspond to different adjustment strategies, thereby improving the adaptability and execution efficiency of the system in different environments. The signal parameter adjustment template with the first priority is called first because this step involves the preliminary adjustment of the optimal parameters. The purpose is to quickly set the chip parameters and perform preliminary optimization of the signal reception sensitivity.

[0050] More specifically, the current signal receiving sensitivity of the Bluetooth chip is obtained, which is usually measured through the chip's receiving module, demodulation module or feedback from other systems to determine whether the current signal receiving sensitivity meets the preset threshold. For example, if the set goal is for the minimum receiving sensitivity to reach a certain level (such as a certain dBm value), the system will compare to determine whether it meets the standard. The signal receiving sensitivity is obtained and determined to meet the preset threshold. The purpose is to ensure that the Bluetooth chip can stably receive effective signals in different environments. If the receiving sensitivity does not meet the standard, it is necessary to further adjust the parameters to improve the receiving performance. By comparing with the preset threshold, the lower limit of the signal quality can be accurately controlled to ensure that the system will not affect the communication performance due to weak or poor signal quality.

[0051] More specifically, if the signal receiving sensitivity still does not reach the preset threshold after the first priority signal parameter adjustment template is executed, the system will call the second priority signal parameter adjustment template according to the difference between the sensitivity and the preset threshold, and execute the second priority template. More RF parameters, gain, filter settings, demodulator thresholds, etc. may be adjusted to further optimize the signal receiving sensitivity. When the signal receiving sensitivity does not meet the standard, the system will take a step-by-step optimization approach to make adjustments. The second priority signal parameter adjustment template may adjust deeper parameters or make stronger adjustments for specific environmental conditions. Gradual adjustments can avoid over-adjustment or system instability caused by over-optimization. The second priority template may contain more detailed adjustments for specific signal environments, such as adjusting certain demodulation parameters or increasing signal amplification, etc., which ensures that the system can optimize sensitivity under different signal conditions.

[0052] More specifically, if the adjustment of the second priority still does not reach the preset signal reception sensitivity, the system will continue to make more adjustments according to the preset rules, and may call up a signal parameter adjustment template with a lower priority, and repeat the aforementioned 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 does not meet the standard, the subsequent steps will continue until the signal reception sensitivity meets the requirements. By continuously adjusting until the standard is met, the system is highly adaptable and can find the best parameter configuration in a complex and changing signal environment. 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 repeated adjustment process enables the system to optimize the receiving sensitivity from multiple angles and gradually find the most suitable parameter configuration, thereby improving the stability and reliability of the system.

[0053] More specifically, when the signal reception sensitivity reaches the preset standard, the system confirms that all adjustments are completed and locks the final RF communication parameters and demodulator parameter settings. These final parameters will be maintained in subsequent Bluetooth communication processes and used for actual signal reception. Confirming the final parameter settings can ensure that the system can stably meet the reception sensitivity standards in actual use. Through a series of dynamic adjustments, the system can maintain good communication quality in different signal environments.

[0054] Preferably, the steps of synchronously monitoring the signal effect of the Bluetooth chip, adjusting and optimizing the signal parameter adjustment scheme according to the result of the synchronous monitoring, and continuing to dynamically adjust the RF communication parameters and demodulator parameters of the Bluetooth chip in real time by adjusting the optimized signal parameter adjustment scheme include: S41: recording the signal received by the Bluetooth chip to obtain a received signal sequence of the Bluetooth chip; S42: Analyzing 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; S43: When the Bluetooth chip is in the low-power mode and the signal effect synchronization monitoring feature shows that the signal receiving sensitivity of the Bluetooth chip does not meet the specified standard, the Bluetooth chip is driven to switch to the precise mode and execute the signal parameter adjustment scheme corresponding to the precise mode; S44: When the Bluetooth chip is in the precision mode and the signal effect synchronization monitoring feature shows that the signal receiving sensitivity of the Bluetooth chip does not meet the specified standard, the Bluetooth chip is driven to switch to the full power adjustment mode; S45: The Bluetooth chip in full power adjustment mode performs parameter deployment of the highest power for the RF communication parameters and the demodulator parameters, and gradually performs a test of parameter reduction on the RF communication parameters and the demodulator parameters until the RF communication parameters and the demodulator parameters whose signal receiving sensitivity of the Bluetooth chip meets the specified standards are obtained.

[0055] Specifically, the signals received by the Bluetooth chip are recorded 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 the signal in the current communication environment. These signal sequences provide raw data for subsequent analysis of the signal-to-noise ratio (SNR), bit error rate (BER) and modulation error ratio (MER).

[0056] More specifically, based on the recorded received signal sequence, the signal effect of the Bluetooth chip at the current moment is analyzed, including: Signal-to-Noise Ratio (SNR): evaluates the ratio of signal to noise, reflecting the signal quality, Bit Error Rate (BER): detects the number of erroneous bits through the received bit stream, evaluates the decoding quality, Modulation Error Ratio (MER): measures the error of the modulated signal, reflecting the accuracy of the modulation and demodulation process. These parameters are 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 adjustments. Using 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 to ensure that the communication quality meets the standards.

[0057] More specifically, when the system detects that the Bluetooth chip is in low-power mode and the signal reception sensitivity does not meet the predetermined standard (the signal quality is detected to be substandard through the synchronous monitoring feature), the system will drive the Bluetooth chip to switch to precise mode. After switching to precise mode, the corresponding signal parameter adjustment plan will be executed to improve the signal quality. When the Bluetooth chip has switched to precise mode, but the signal effect still does not meet the standard, the system will drive the chip to switch to full-power regulation mode. Switching between low-power and precise modes: low-power mode is usually used for Bluetooth devices in standby or low data transmission, when the communication requirements are lower. The precise mode is the working mode when the communication quality requirements are higher, and more detailed signal optimization can be performed. When the signal reception sensitivity does not meet the standard, switching to precise mode can increase the reception performance.

[0058] More specifically, when the signal standard is still not met in the precision mode, switching to the full power mode can ensure that the receiving sensitivity meets the requirement by increasing the RF power. The full power mode provides the system with the strongest signal output capability, but at this time the system will gradually adjust the RF communication and demodulator parameters to reduce power output and avoid unnecessary power consumption. In the full power adjustment mode, the Bluetooth chip will first set the RF communication parameters and the demodulator parameters to the highest power to ensure that the signal receiving sensitivity is maximized. Then, the system will gradually lower the power of the RF communication parameters and the demodulator parameters, and perform a gradual downward adjustment test. After each reduction, the system will detect the signal effect (such as receiving sensitivity) and determine whether it meets the predetermined standard. If at a certain stage, the signal If the signal reception sensitivity meets the standard, the current RF communication and demodulator parameters are locked; in full power mode, by setting it to the highest power first, ensure 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 setting that can maintain good signal reception sensitivity without consuming too much battery resources. Through step-by-step testing, excessive power consumption caused by excessive adjustment can be effectively avoided, and energy can be saved while ensuring communication quality. After multiple adjustments and tests, the Bluetooth chip will eventually obtain a set of RF communication parameters and demodulator parameters that meet the signal reception sensitivity standards. These parameters will be used as the final configuration and used in daily communication processes.

[0059] It is understandable that through this gradual adjustment process, the system can not only find the best RF communication parameters and demodulator parameters, but also ensure the stability and high performance of the system in different signal environments. This ensures that the quality of Bluetooth communication 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.
