[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] Reference Figure 1 As shown, the first aspect of the present invention provides a method for synchronous transmission of Bluetooth headsets, including: analyzing the connection performance of each Bluetooth headset, and determining the stable connection degree value of each Bluetooth headset, thereby matching the data transmission synchronization evaluation threshold of each Bluetooth headset.

[0034] Specifically, the stable connection degree value of each Bluetooth headset, the specific data acquisition process is:

[0035] By analyzing the connection performance of each Bluetooth headset, the signal index information and characteristic index information of each Bluetooth headset are obtained.

[0036] The signal indicator information of each Bluetooth headset is used to extract the signal strength and noise intensity at each connection time point.

[0037] It should be explained that the above-mentioned signal strength is obtained by connecting the Bluetooth signal strength sensor to the Bluetooth headset and pairing them, and measuring them at different time points of the Bluetooth headset to obtain the signal strength data of the Bluetooth headset at each connection time point; the noise intensity is obtained by connecting the noise sensor to the Bluetooth headset and placing it at the location that needs to be monitored. When the Bluetooth headset is operating, start the sensor and obtain the noise data through big data calculation, observe the noise intensity value output by the sensor, and thereby obtain the noise intensity of the Bluetooth headset at each connection time point.

[0038] According to the signal strength of each Bluetooth headset at each connection time point, a signal strength change curve of each Bluetooth headset is constructed, such as Figure 3 As shown, the horizontal axis of the signal strength change line is the connection time point, the unit is second; the vertical axis is the absolute value of the signal strength, the unit is decibel milliwatt.

[0039] Extract and count the attenuation angle values ​​corresponding to each signal attenuation of each Bluetooth headset, such as Figure 3 As shown, the specific process of obtaining the attenuation angle value is as follows:

[0040] According to the signal strength change curve, a signal attenuation straight line is located, and according to Figure 3 The first horizontal straight line (2) in the image is obtained, and the minimum angle value of the intersection between the signal attenuation straight line and the first horizontal straight line (2) is obtained, and recorded as the attenuation angle value.

[0041] The signal strength stability corresponding to each attenuation angle value interval defined in the Bluetooth authentication database is matched, thereby obtaining the signal strength stability corresponding to each signal attenuation of each Bluetooth headset.

[0042] The signal strength and noise strength of each Bluetooth headset at each connection time point are processed by ratio, so as to obtain the signal-to-noise ratio of each Bluetooth headset at each connection time point.

[0043] The defined signal-to-noise ratio of each Bluetooth headset is extracted from the Bluetooth authentication database, and the signal stability strength evaluation coefficient of each Bluetooth headset is analyzed. In a specific embodiment, multiple sets of data can be collected, including signal strength and other factors that may affect signal stability, and then a linear regression model can be trained. The linear regression model is applied to cloud computing to predict the signal stability strength evaluation coefficient, so as to obtain the signal stability strength evaluation coefficient of each Bluetooth headset.

[0044] The signal stability strength evaluation coefficient of each Bluetooth headset mentioned above is obtained by comprehensively processing the signal strength stability, signal-to-noise ratio and noise intensity in this embodiment to obtain data on the signal stability strength of each Bluetooth headset. This embodiment adopts a more accurate calculation method to obtain the signal stability evaluation coefficient. The specific calculation method is as follows:

[0045]

[0046] In the formula, τ r is the signal stability strength evaluation coefficient of the rth Bluetooth headset. In this embodiment, the instability of signal strength may cause the signal of the Bluetooth headset to be intermittent during operation. At the same time, if the signal strength changes drastically in a short period of time, the Bluetooth headset may be temporarily disconnected; a low signal-to-noise ratio may cause the signal to be mixed with noise, so that the audio data transmitted by the Bluetooth headset will have a large amount of external noise; high noise intensity may interfere with the data transmission and reception of the Bluetooth headset. By comprehensively considering these factors and taking corresponding improvement measures, the signal stability strength of the Bluetooth headset can be more accurately evaluated, so as to prepare for the subsequent screening of Bluetooth headsets with better quality and performance.

[0047] A1 is the influence factor of the predefined signal strength stability corresponding to the unit value, A2 is the correction factor corresponding to the predefined signal-to-noise ratio, A3 is the influence factor corresponding to the predefined noise intensity unit value, XP rpIt represents the signal strength smoothness corresponding to the p-th signal attenuation of the r-th Bluetooth headset, where the signal strength smoothness is inversely proportional to the attenuation angle value, which means that as the attenuation angle value increases, the signal strength smoothness will decrease. In other words, the stability of the signal strength during propagation decreases with the increase of the attenuation angle. The increase in the attenuation angle value may mean that the signal transmission path is more complicated or the distance is longer, which will increase the possibility of signal interference, thereby affecting the signal strength stability of the Bluetooth headset.

[0048] XZ rh It represents the signal-to-noise ratio of the rth Bluetooth headset at the hth connection time point. The above signal-to-noise ratio refers to the ratio of signal strength to noise strength, which is used to measure the relative strength of signal and noise during the transmission process. A higher signal-to-noise ratio usually means that the signal is relatively strong and the noise is relatively small, which helps to improve the quality and reliability of the Bluetooth headset signal.

[0049] XQ rh Represents the noise intensity of the rth Bluetooth headset at the hth connection time point. The noise intensity generally refers to the intensity of other undesired audio components in the received audio signal except the desired audio content. These undesired audio components can be noise introduced by various interference signals, background noise or other interference sources.

[0050] ΔXZ r It represents the defined signal-to-noise ratio of the rth Bluetooth headset, where the defined signal-to-noise ratio refers to the minimum value specified when analyzing the signal-to-noise ratio.

[0051] p represents the number of each signal attenuation, p=1,2,3,...,u, u represents the number of signal attenuation, h represents the number of each connection time point, h=1,2,3,...,y, y represents the number of connection time points, r represents the number of each Bluetooth headset, r=1,2,3,...,q, q represents the number of Bluetooth headsets.

[0052] According to the characteristic indicator information of each Bluetooth headset, the data transmission error correction rate of each Bluetooth headset within a set connection transmission period is extracted.

[0053] It should be explained that the above-mentioned data transmission error correction rate is obtained through the functions of the Bluetooth protocol stack and the physical layer. The specific process is to monitor and predict the error rate in real time through the cloud computing platform, so as to obtain the data transmission error correction rate within the set connection transmission cycle.

[0054] The data transmission error definition correction rate of each Bluetooth headset is extracted from the Bluetooth authentication database, and the characteristic indicator evaluation coefficient of each Bluetooth headset is analyzed. In a specific embodiment, an integrated learning algorithm such as a random forest can be used to combine multiple decision trees for training and prediction to evaluate the importance of each characteristic indicator, and by inputting factors related to the characteristic indicators of the Bluetooth headset, such as the version model, the characteristic indicator evaluation coefficient of each Bluetooth headset is obtained.

[0055] The characteristic index evaluation coefficient of each Bluetooth headset mentioned above is obtained by comprehensively processing the data transmission error correction rate and the data transmission error definition correction rate in this embodiment to obtain data on the characteristic index degree of each Bluetooth headset. This embodiment adopts a more accurate calculation method to obtain the coefficient. The specific calculation method is as follows:

[0056]

[0057] In the formula, Represents the characteristic index evaluation coefficient of the rth Bluetooth headset. In this embodiment, the data transmission error correction rate is easily affected by environmental interference. For example, in a complex electromagnetic environment, it may cause increased signal interference, which in turn affects the stability and error correction capability of the Bluetooth headset data transmission. In order to reduce the above negative impact, it is necessary to establish a more comprehensive and accurate evaluation model when analyzing the characteristic indicators of each Bluetooth headset, and determine the importance and weight of the evaluation indicators according to specific needs and usage scenarios, so as to screen out Bluetooth headsets that are more in line with the application scenarios and complex environments.

[0058] TW r It represents the data transmission error correction rate of the rth Bluetooth headset within the set connection transmission cycle, where the data transmission error correction rate represents the ratio of transmission data errors that the system can automatically detect and correct within the set connection transmission cycle. This indicator reflects the error handling ability of the Bluetooth device during the data transmission process. A higher correction rate means that the device has a stronger error correction capability, can more effectively handle errors that occur during the transmission process, and improve the reliability and stability of data transmission.

[0059] ΔTW r It represents the data transmission error limit correction rate of the rth Bluetooth headset, and the data transmission error limit correction rate is the permitted lower limit value specified when analyzing the data transmission error correction rate.

[0060] M1 is an evaluation correction factor corresponding to a preset data transmission error correction rate.

[0061] Furthermore, the specific analysis process of the stable connection degree value of each Bluetooth headset is as follows:

[0062] In a specific embodiment, a neural network model can be constructed to learn the complex relationship between the characteristic indicators of the Bluetooth headset and the degree of stable connection by training the network, so as to obtain the stable connection degree value of each Bluetooth headset.

[0063] The above-mentioned stable connection degree values ​​of each Bluetooth headset are obtained by comprehensively processing the signal stability strength evaluation coefficient of each Bluetooth headset and the characteristic index evaluation coefficient of each Bluetooth headset in this embodiment to obtain data on the stable connection degree of each Bluetooth headset. This embodiment adopts a more accurate calculation method to obtain the value. The specific calculation method is as follows:

[0064]

[0065] In the formula, ε r It represents the stable connection degree value of the rth Bluetooth headset. In this embodiment, if the weight of the signal stability strength or the characteristic index is too high or too low, it may cause deviation in the evaluation of the connection stability; if the data of the signal stability strength and the characteristic index are inaccurate or there are errors, it will affect the accuracy of the evaluation; the Bluetooth signal is easily affected by environmental factors, such as obstacles, signal interference, etc., which may affect the evaluation result of the connection stability; therefore, when evaluating the connection stability of the Bluetooth headset, it is necessary to comprehensively consider the above factors to ensure that the evaluation process is accurate and reliable. By reasonably selecting evaluation indicators, ensuring data accuracy, selecting appropriate models, and considering environmental factors and user needs, the stable connection degree of the Bluetooth headset can be more accurately evaluated.

[0066] τ r is the signal stability strength evaluation coefficient of the rth Bluetooth headset, represents the characteristic index evaluation coefficient of the rth Bluetooth headset, B1 is the weight corresponding to the preset signal stability strength evaluation coefficient, B2 is the weight corresponding to the preset characteristic index evaluation coefficient, and e is a natural constant.

[0067] Specifically, the data transmission synchronization evaluation threshold of each Bluetooth headset is matched, and the specific matching process is:

[0068] The stable connection degree value of each Bluetooth headset is matched with the data transmission synchronization evaluation threshold value corresponding to each set stable connection degree value interval to obtain the data transmission synchronization evaluation threshold value of each Bluetooth headset.

[0069] In this embodiment, the data transmission synchronization evaluation threshold of each of the above-mentioned Bluetooth headsets is obtained in the following specific process:

[0070] A data acquisition module is implanted in each Bluetooth headset to monitor the stable connection degree value in real time and upload these data to the cloud database; a data processing and analysis module is established on the cloud computing platform to process and analyze the uploaded stable connection degree value; each stable connection degree value interval and the corresponding data transmission synchronization evaluation threshold are set, and the stable connection degree value of each Bluetooth headset is matched with the set interval through the cloud computing platform to calculate the corresponding data transmission synchronization evaluation threshold; at the same time, a real-time monitoring system is established in the cloud to continuously monitor the data transmission synchronization evaluation threshold of each Bluetooth headset, and adjust and optimize it according to real-time data.

[0071] In a specific embodiment, the present invention can improve the two-way communication function between Bluetooth headsets and data transmission equipment by obtaining signal index information and feature index information of each Bluetooth headset and comprehensively determining the stable connection degree value of each Bluetooth headset, while reducing the risk of data interference and distortion, thereby improving the clarity and realism of data transmission.

[0072] Each Bluetooth headset is stably connected to the data transmission device, the transmission audio between each Bluetooth headset and the data transmission device is obtained, and the data transmission synchronization evaluation index between each Bluetooth headset and the data transmission device is analyzed.

[0073] Specifically, the data transmission synchronization evaluation index between each Bluetooth headset and the data transmission device, the specific data acquisition process is:

[0074] The transmission audio between each Bluetooth headset and the data transmission device is randomly arranged to obtain each detection audio point, and the response reception time of each Bluetooth headset at each detection audio point and the response transmission time of the data transmission device at each detection audio point are obtained. The maximum delay duration of the audio transmission between each Bluetooth headset and the data transmission device is obtained through difference processing.

[0075] It should be explained that the response reception time of each Bluetooth headset at each detection audio point and the response transmission time of the data transmission device at each detection audio point can be recorded by a time synchronization sensor.

[0076] The transmitted audio is divided into various transmitted audio segments, the receiving time of each Bluetooth headset in receiving each transmitted audio segment is extracted, and the ratio is processed with the statistical number of bytes of each transmitted audio segment to obtain the receiving rate of each Bluetooth headset in each transmitted audio segment, and the maximum receiving rate of each Bluetooth headset is screened out.

[0077] It needs to be explained that the reception time of the above-mentioned Bluetooth headsets when receiving each transmitted audio segment. Since the Bluetooth headset will consume power during the reception of the audio segment, the power consumption of the Bluetooth headset when receiving each transmitted audio segment can be monitored through a power sensor, and the reception time of the Bluetooth headset when receiving each transmitted audio segment can be inferred.

[0078] It needs to be further explained that the number of bytes of each transmitted audio segment refers to the number of bytes contained in each transmitted audio segment during the audio transmission process, that is, the capacity of the audio data.

[0079] The permitted audio transmission delay duration and reference receiving rate of each Bluetooth headset are extracted from the Bluetooth authentication database, thereby analyzing the data transmission synchronization evaluation index between each Bluetooth headset and the data transmission device.

[0080] Furthermore, the data transmission synchronization evaluation index between each Bluetooth headset and the data transmission device, in a specific embodiment, can utilize a delay estimation algorithm to estimate the delay between the two by analyzing the time difference between receiving and sending data packets, so as to obtain the data transmission synchronization evaluation index between each Bluetooth headset and the data transmission device.

[0081] The data transmission synchronization evaluation index between each Bluetooth headset and the data transmission device is obtained by comprehensively processing the maximum delay time of audio transmission and the maximum receiving rate in this embodiment to obtain data on the data transmission synchronization evaluation degree between each Bluetooth headset and the data transmission device. This embodiment adopts a more accurate calculation method to obtain the data. The specific calculation method is as follows:

[0082] In the formula, β r is the data transmission synchronization evaluation index between the rth Bluetooth headset and the data transmission device. In this embodiment, if there is a large data transmission delay, the synchronization of audio data between the Bluetooth headset and the device may be affected, resulting in the problem of asynchronous audio playback; and too high a data transmission rate may cause data loss or buffer overflow, thereby causing the loss or damage of audio data, affecting the real-time transmission and processing of audio data, and further reducing the audio quality; therefore, when designing and optimizing the audio transmission system, these factors need to be comprehensively considered to ensure data transmission synchronization and audio quality.

[0083] T r It is the maximum delay time of audio transmission between the rth Bluetooth headset and the data transmission device, where the maximum delay time of audio transmission refers to the maximum delay time monitored during the transmission of audio data from the data transmission device to the Bluetooth headset. In other words, this parameter represents the longest time interval between the sending and receiving of audio data.

[0084] ΔT r is the permitted audio transmission delay duration of the rth Bluetooth headset, where the permitted audio transmission delay duration represents the maximum delay time allowed between the Bluetooth headset and the data transmission device during audio transmission.

[0085] S r is the maximum receiving rate of the rth Bluetooth headset, where the maximum receiving rate refers to the maximum data rate that the Bluetooth headset can receive and process during the audio data transmission process.

[0086] ΔS r Represents the reference receiving rate of the rth Bluetooth headset, where the reference receiving rate represents the maximum limit of the speed of sending audio data from the data transmission device to the Bluetooth headset.

[0087] D1 represents an evaluation correction factor corresponding to a predefined maximum audio transmission delay duration, and D2 represents an evaluation correction factor corresponding to a predefined maximum receiving rate.

[0088] According to the data synchronization transmission evaluation index between each Bluetooth headset and the data transmission device and the data transmission synchronization evaluation threshold of each Bluetooth headset, the transmission optimization value of each Bluetooth headset is analyzed, and the synchronization transmission degree of each Bluetooth headset is optimized.

[0089] Specifically, the transmission optimization value of each Bluetooth headset may be optimized by using an optimization algorithm in a specific embodiment to perform parameter optimization for the delay state during the transmission process, so as to obtain the transmission optimization value of each Bluetooth headset.

[0090] The transmission optimization value of each Bluetooth headset mentioned above is obtained by processing the data transmission synchronization evaluation index between each Bluetooth headset and the data transmission device and the data transmission synchronization evaluation threshold of each Bluetooth headset in this embodiment, and comprehensively analyzing the data on the transmission optimization degree of each Bluetooth headset. This embodiment adopts a more accurate calculation method to obtain the data, and the specific calculation method is as follows:

[0091]

[0092] In the formula, μ r is the transmission optimization value of the rth Bluetooth headset. In this embodiment, the data transmission synchronization evaluation index is an important indicator for evaluating the data transmission synchronization performance. If this index is inaccurate or unstable, it means that the Bluetooth headset needs to be optimized to a greater extent. The data transmission synchronization evaluation threshold directly affects when the data transmission synchronization is considered to be poor and the optimization measures are triggered. If the threshold is set unreasonably, frequent optimization operations may be caused or the opportunity to optimize is missed. By comprehensively considering the above factors, the transmission performance of each Bluetooth headset can be more comprehensively evaluated and optimized, thereby improving user experience and data synchronization transmission efficiency.

[0093] β r is the data transmission synchronization evaluation index between the rth Bluetooth headset and the data transmission device, Δβ r The data transmission synchronization evaluation threshold of the rth Bluetooth headset refers to a standard reference value matched when evaluating the stable connection degree of the Bluetooth headset. It is usually used to determine whether the synchronization of data transmission meets a certain standard so as to take corresponding optimization and adjustment measures.

[0094] E is the transmission optimization factor corresponding to the set data transmission synchronization evaluation index.

[0095] Furthermore, the synchronization transmission degree of each Bluetooth headset is optimized, and the specific optimization process is as follows:

[0096] The transmission optimization value of each Bluetooth headset is matched with the synchronization transmission optimization degree level corresponding to each transmission optimization value interval defined in the Bluetooth authentication database to obtain the synchronization transmission optimization degree level corresponding to each Bluetooth headset, thereby optimizing the synchronization transmission degree of each Bluetooth headset.

[0097] In this embodiment, the synchronization transmission degree of each Bluetooth headset is optimized, and the specific optimization process is as follows:

[0098] First, make sure that the distance between the Bluetooth headset and the data transmission device is within the effective range, avoid environmental and other interference factors, and check the battery power of the device to ensure sufficient power to maintain stable performance; at the same time, make sure that the software and drivers of the Bluetooth headset and data transmission device are the latest versions to ensure optimal compatibility and performance; according to the device performance requirements, adjust the data transmission parameters such as data packet size, transmission rate, etc. to obtain better synchronous transmission effect; if there is a connection problem, try to reconnect the Bluetooth device or reset the device's network settings to solve the connection synchronization problem; and use relevant Internet programs to monitor the synchronization performance of data transmission, identify problems in time and solve them, so as to further optimize the degree of synchronous transmission.
