Advanced audio of a bluetooth TWS (True Wireless Stereo) is to connect different channels between a master bluetooth device and a slave bluetooth device through bluetooth, so that the different channels play the same audio file. When the distance between the master TWS bluetooth device and the slave TWS bluetooth device is relatively close, there may be situations where the data packets received by the master TWS bluetooth device and the slave TWS bluetooth device are different, such as adjacent channel interference of audio signals, and situations where the data packets received by the master TWS bluetooth device and the slave TWS bluetooth device and/or the data packets sent by the master TWS bluetooth device and the slave TWS bluetooth device are abnormal, which may cause the numbers of audio data packets received by the master TWS bluetooth device and the slave TWS bluetooth device to be inconsistent, thereby causing the TWS bluetooth device to play song katon.

At present, the adjacent channel interference is generally handled by Automatic Gain Control (AGC) through hardware, and the AGC is an Automatic Control method for automatically adjusting the Gain of an amplifying circuit according to the signal intensity.

Detailed Description

Fig. 1 is a flowchart of an embodiment of a TWS device communication data configuration method of the present invention, which includes the following steps.

Step S100, the TWS main device obtains communication data communicated with the terminal device, wherein the communication data comprises data parameters and adjusting parameters, the data parameters at least comprise communication signal intensity and data packet error information, and the adjusting parameters at least comprise data transceiving sensitivity and communication frequency points.

Specifically, referring to fig. 2, as can be seen from fig. 2, the TWS master device and the terminal device establish communication, and data transmission is performed between the TWS master device and the terminal device, while the TWS slave device listens to data transmitted between the TWS master device and the terminal device. In the embodiment, the TWS device includes, but is not limited to, a TWS headset and a TWS speaker, and the terminal device may be a smart phone, a notebook computer, a television, or the like. After the communication connection between the TWS main equipment and the terminal equipment is established, the TWS main equipment acquires communication data communicated between the TWS main equipment and the terminal equipment, wherein the communication data comprises data parameters and adjusting parameters, the data parameters at least comprise communication signal intensity and data packet error information, and the adjusting parameters at least comprise data transceiving sensitivity and communication frequency points. Note that the frequency point is a number given to a fixed frequency. It can be determined through the packet error information that the data packets transmitted between the TWS host device and the terminal device belong to erroneous data packets, and the erroneous data packets pass through the communication frequency point and are received at the time point through the error identifier, that is, the erroneous data packets carry the error identifier, which is not limited in the present embodiment. It is understood that when the TWS master device receives a packet that is sent by the terminal device as an erroneous packet, the TWS master device does not respond to the packet, or the TWS master device cannot successfully respond to the packet. The data transmitted between the TWS host device and the terminal device may include other data, such as audio data, in addition to the communication data.

Further, in the step S100, the step of acquiring the communication signal strength of the communication between the TWS master device and the terminal device includes:

step a, obtaining the communication signal intensity detected in a preset time length, and selecting a preset number of communication signal intensities in the obtained communication signal intensity.

And b, calculating the average value of the communication signal intensities of the preset number, and taking the average value as the communication signal intensity of the communication between the TWS main equipment and the terminal equipment.

Further, the process of the TWS master device acquiring the communication signal strength is as follows: in the communication process between the TWS main equipment and the terminal equipment, the TWS main equipment can detect the communication signal intensity between the TWS main equipment and the terminal equipment at regular time or in real time, and the detected communication signal intensity in the preset time length is obtained. The preset duration may be set according to specific needs, and the size of the preset duration is not specifically limited in this embodiment. After the TWS master device obtains the communication signal intensity detected in the preset time, the TWS master device selects the preset number of communication signal intensities from the obtained communication signal intensities, calculates the average value of the selected preset number of communication signal intensities, and takes the calculated average value as the communication signal intensity communicated with the terminal device, namely takes the calculated average value as the communication signal intensity in the communication data. Wherein the preset number may be set to 8, 10, 15, etc. Specifically, in the process of selecting the preset number of communication signal strengths from the acquired communication signal strengths, the TWS master device may randomly select the preset number of communication signal strengths from the acquired communication signal strengths, or may select the preset number of communication signal strengths according to a preset selection rule. For example, the selection rule may select the detected communication signal strength at a specific time point, or select a communication signal strength at a certain number of intervals. It should be noted that the distance between the TWS host device and the terminal device can be calculated by the communication signal strength, and the averaging of the communication signal strength can reflect the distance change between the TWS host device and the terminal device over a period of time, thereby adjusting the data transceiving sensitivity in the communication data.

Step S200, judging whether the communication signal intensity is within a preset signal intensity range; if the communication signal strength is not within the signal strength range, executing step S300; if the communication signal strength is within the signal strength range, step S400 is executed.

And step S300, adjusting the data transceiving sensitivity, and executing step S100 after adjusting the data transceiving sensitivity.

After the TWS master device acquires the communication data, the TWS master device determines whether the communication signal strength in the communication data is within a preset signal strength range, wherein an upper limit value and a lower limit value of the signal strength range may be set according to specific needs, for example, the lower limit value of the signal strength range may be set to-40 dBm (decibel-milliwatt), the upper limit value may be set to-30 dBm, or the lower limit value of the signal strength range may be set to-50 dBm, and the upper limit value may be set to-25 dBm. If the communication signal intensity of the TWS master device is not within the signal intensity range, the TWS master device adjusts data transceiving sensitivity in communication data to obtain adjusted data transceiving sensitivity, communicates with the terminal device according to the adjusted data transceiving sensitivity, and reacquires communication data in the communication process with the terminal device. It is to be understood that the data transceiving sensitivity in the communication data that is reacquired is the adjusted data transceiving sensitivity. Referring to fig. 3, in fig. 3, the horizontal axis represents time for detecting the intensity of the communication signal, and the vertical axis represents the intensity of the communication signal detected each time, the unit of the intensity of the communication signal being dBm (decibel-milliwatt). It should be noted that, when the communication signal strength is not within the signal strength range, the power consumption of the TWS master device for receiving and transmitting data will increase; when the communication signal strength is within the signal strength range, the TWS master device may reduce power consumption for receiving and transmitting data relative to when the communication signal strength is not within the signal strength range. When the data transceiving sensitivity is adjusted, the magnitude of the communication signal strength is changed.

Further, in step S300, the adjusting of the data transmission/reception sensitivity includes:

step S310, acquiring target sensitivity corresponding to the TWS main equipment, and judging whether the data transceiving sensitivity is smaller than the target sensitivity or larger than the target sensitivity; if the data transceiving sensitivity is less than the target sensitivity, performing step S320; if the data transceiving sensitivity is greater than the target sensitivity, step S330 is performed.

Step S320, increasing the data transceiving sensitivity to the target sensitivity.

Step S330, reducing the data transceiving sensitivity to the target sensitivity.

Specifically, the process of adjusting the data transceiving sensitivity by the TWS master device is as follows: the TWS master device acquires preset target sensitivity and judges whether data transceiving sensitivity in communication data is smaller than the target sensitivity or larger than the target sensitivity. If the TWS master device judges that the data transceiving sensitivity is smaller than the target sensitivity, the TWS master device increases the data transceiving sensitivity to the target sensitivity so that the adjusted data transceiving sensitivity is equal to the target sensitivity; if the TWS master device judges that the data transceiving sensitivity is greater than the target sensitivity, the TWS master device reduces the data transceiving sensitivity to the target sensitivity, and the adjusted data transceiving sensitivity is equal to the target sensitivity. Specifically, referring to fig. 4, fig. 4 is a schematic circuit structure diagram of sensitivity adjustment according to an embodiment of the present invention. As can be seen from fig. 4, the sensitivity adjustment circuit is composed of a capacitor C and a resistor R, the resistor may be a variable resistor, and the size of the data transceiving sensitivity is adjusted by adjusting the size of the resistance value; the size of data receiving and transmitting sensitivity can be adjusted by adjusting the current of the injection capacitor; further, the magnitude of the data transmission/reception sensitivity may be adjusted by adjusting the magnitudes of the current injected into the resistor and the capacitor at the same time.

The target sensitivity may be set in advance, or may be determined by a difference between the communication signal strength and the signal strength range in the communication data. Specifically, a signal difference between the communication signal strength and the signal strength range in the communication data is calculated, and it can be understood that, when the communication signal strength is greater than the upper limit value of the signal strength range, the communication signal strength is subtracted by the upper limit value of the signal strength range to obtain a signal difference; and when the communication signal intensity is smaller than the lower limit value of the signal intensity range, subtracting the communication signal intensity from the lower limit value of the signal intensity range to obtain a signal difference value, and determining the target sensitivity according to the signal difference value. At this time, in the TWS master device, a mapping relationship between the signal difference and the target sensitivity is stored in advance, and in the mapping relationship, one signal difference may correspond to one target sensitivity, or a plurality of signal differences may correspond to one target sensitivity.

Step S400, calculating the packet error rate of the data packet received by the TWS master device according to the packet error information, and judging whether the packet error rate is less than a preset error rate; if the error rate is greater than or equal to the error rate, executing step S500; if the error rate is less than the error rate, step S600 is performed.

S500, adjusting the communication frequency point, and executing the step S100 after adjusting the communication frequency point.

In this embodiment, the TWS host device is in frequency modulation communication, and therefore, the TWS host device may determine and count the number of erroneous packets in the data packets received from the terminal device, and also determine the communication frequency point of the currently received data packet. When the TWS master device determines that the communication signal strength in the communication data is within the signal strength range, the TWS master device calculates the packet error rate of the received packets according to the packet error information in the communication data. Specifically, when the TWS master device calculates the packet error rate, it calculates the number of packet errors belonging to the erroneous packet in a specific number of currently acquired packets, and then divides the number of packet errors by the specific number to obtain the packet error rate. If the TWS master calculates that there are 15 erroneous packets out of the currently acquired 100 packets, 15 ÷ 100 ═ 0.15, that is, the packet error rate is 0.15. After the TWS master device calculates the packet error rate, the TWS master device determines whether the packet error rate is smaller than a preset error rate, where the size of the error rate is not limited in this embodiment, and a user may set the size of the error rate according to specific needs. And if the TWS main equipment judges that the packet error rate is greater than or equal to the error rate, the TWS main equipment adjusts the communication frequency point to obtain the adjusted communication frequency point, communicates with the terminal equipment through the adjusted communication frequency point, and acquires the communication data again after the communication frequency point is adjusted.

Further, in step S500, the step of adjusting the communication frequency point includes:

and c, determining the interfered target frequency points in the communication frequency points, and sequencing the target frequency points from large to small according to the interference degree to obtain the sequenced target frequency points.

Further, the process of the TWS master device adjusting the communication frequency point is as follows: and the TWS main equipment determines the interfered communication frequency point in the communication frequency points and takes the interfered communication frequency point as a target frequency point. Specifically, the factors disturbing the communication frequency point include environment, antenna, WiFi, and the like. When the data packet received by a certain communication frequency point has an error data packet, the communication frequency point is judged to be interfered. After the TWS master device determines the target frequency point, the TWS master device sorts the target frequency point from large to small according to the interference degree to obtain the sorted target frequency point. Specifically, the number of error data packets in data packets received by each target frequency point within the same time is calculated, and the larger the number of error data packets is, the larger the interference degree of the target frequency point is; and calculating the packet error rate corresponding to the data packet received by each target frequency point in the same time, wherein the larger the packet error rate is, the larger the interference degree of the target frequency point is.

And d, determining the number of the frequency points to be discarded according to the packet error rate, discarding the target frequency points from front to back according to the number of the frequency points in the sequenced target frequency points, and taking the rest communication frequency points as communication frequency points for receiving data.

The TWS main device determines the number of the frequency points to be discarded according to the packet error rate, wherein the packet error rate is obtained by calculating according to the packet error information of the data packet and is the integral packet error rate of the data packet received by the TWS main device. In this embodiment, a mapping relationship between the packet error rate and the number of frequency points of the frequency point to be discarded may be preset, and in the mapping relationship, the larger the packet error rate is, the larger the number of frequency points of the frequency point to be discarded is. And after the TWS main equipment determines the number of the frequency points, the TWS main equipment discards the target frequency points from front to back in the sequenced target frequency points according to the number of the frequency points, and uses the remaining communication frequency points as communication frequency points for receiving data. It can be understood that the number of discarded target frequency points is equal to the determined number of frequency points. In other embodiments, after the TWS master device determines the interfered target frequency points, the TWS master device may also sequence the target frequency points according to the interference degree from small to large to obtain the sequenced target frequency points, then discard the target frequency points from back to front in the sequenced target frequency points according to the number of frequency points, and use the remaining communication frequency points as communication frequency points for receiving data.

Referring to fig. 5, for example, in the communication channel 2402 and 2480, the TWS master device and the terminal device use 30 communication frequency points (including other communication frequency points such as 2440), and determine the interference degree of each communication frequency point by calculating the number of error data packets in the data packets received by each communication frequency point within the time T. For example, when the communication data includes the interference strength of the 30 communication frequency points, 10 of the communication frequency points are the strongest interference. Therefore, when the TWS master determines that the packet error rate of the receiving terminal device is more than 10% and less than 20%, the TWS master discards 5 communication frequency points of the 10 communication frequency points with the strongest interference; when the TWS master device determines that the packet error rate of the receiving terminal device is above 20%, the TWS master device discards 8 communication frequency points of the 10 communication frequency points with the strongest interference, so as to ensure that the packet error rate of the communication is in the lowest state.

And S600, when the data parameters all meet preset conditions, keeping the adjustment parameters in the current communication data of the TWS master device, and sending the kept adjustment parameters to the TWS slave device, wherein the TWS slave device adjusts according to the adjustment parameters sent by the TWS master device, so that the TWS master device and the TWS slave device work under the same adjustment parameters.

And if the TWS master device judges that the packet error rate is less than the error rate, the TWS master device keeps the adjustment parameters in the current communication data of the TWS master device when the data parameters all meet the preset conditions. It can be understood that, when the packet error rate is less than the error rate, it indicates that the packet error information of the data packet satisfies the predetermined condition, and when the packet error rate is less than the error rate, the communication signal strength is inevitably within the predetermined strength range, that is, the communication signal strength satisfies the corresponding predetermined condition.

And after the TWS master device establishes communication connection with the TWS slave device, the TWS master device sends the maintained adjustment parameters to the TWS slave device. When the TWS slave device receives the adjustment parameter, the TWS slave device adjusts the adjustment parameter to be the same as the received adjustment parameter, so that the TWS master device and the TWS slave device operate under the same adjustment parameter. Specifically, after receiving the adjustment parameter, the TWS slave device determines whether the current adjustment parameter is consistent with the received adjustment parameter, and adjusts the adjustment parameter inconsistent with the received adjustment parameter to be consistent with the received adjustment parameter, and if the current adjustment parameter is consistent with the received adjustment parameter, no adjustment is required.

The method and the device have the advantages that the TWS master device and the TWS slave device communicate by using the same adjustment parameters, the TWS master device and the TWS slave device receive the same amount of data, the problem of large difference of data quantity between the data received by the TWS master device and the data received by the TWS slave device due to adjacent channel interference is solved, the TWS master device solves the adjacent channel interference problem between the TWS master device and the TWS slave device in a mode of combining a plurality of data of signal intensity, data receiving and sending sensitivity and packet error rate of received data packets, the problem that the adjacent channel interference can be solved only by using AGC is avoided, the adjacent channel interference is solved by using a plurality of data, and the success rate of solving the adjacent channel interference is improved.

Further, a second embodiment of the TWS device communication data configuration method of the present invention is proposed.

The second embodiment of the TWS device communication data configuration method differs from the above-mentioned TWS device communication data configuration method in that, referring to fig. 6, the data parameters of the communication data further include the unprocessed audio data amount currently stored by the TWS master device, the adjustment parameters of the communication data further include a play code stream, and if the packet error rate is smaller than the error rate, step S700 is executed:

step S700, judging whether the audio data volume is within a preset data volume range; if the audio data volume is within the data volume range, executing step S600; if the audio data amount is not within the data amount range, step S800 is executed.

In this embodiment, the data parameter of the communication data further includes an unprocessed audio data amount currently stored by the TWS host device, and the parameter adjustment further includes a play code stream. If the TWS master device determines that the packet error rate is smaller than the error rate, the TWS master device determines whether the audio data volume is within a preset data volume range, where an upper limit and a lower limit of the data volume range are preset by a user, and the upper limit and the lower limit of the data volume range are not specifically limited in this embodiment. If the TWS master device determines that the audio data amount is within the preset data amount range, the TWS master device keeps the adjustment parameters in the current communication data when the adjustment parameters all meet preset conditions, and sends the kept adjustment parameters to the TWS slave device, so that the TWS slave device adjusts according to the adjustment parameters sent by the TWS master device, and the TWS master device and the TWS slave device operate under the same adjustment parameters.

Step S800, adjusting the playing code stream of the audio data played by the TWS main equipment, and executing step S600 after adjusting the playing code stream.

Further, in step S800, the step of adjusting the play code stream of the TWS master device for playing the audio data includes:

step S810, judging whether the audio data volume is larger than the upper limit value of the data volume range or smaller than the lower limit value of the data volume range; if the audio data amount is greater than the upper limit value, performing step S820; if the audio data amount is smaller than the lower limit value, step S830 is performed.

Step S820, calculating a first difference between the audio data amount and the upper limit, dividing the first difference by the upper limit to obtain an exceeding ratio of the audio data amount exceeding the data amount range, and increasing a play code stream of the TWS main device playing the audio data according to the exceeding ratio.

Step S830, calculating a second difference between the lower limit value and the audio data amount, dividing the second difference by the lower limit value to obtain a low-out ratio value of the audio data amount lower than the data amount range, and reducing a play code stream of the TWS main device for playing the audio data according to the low-out ratio value.

Further, if the TWS master device determines that the audio data amount is not within the data amount range, the TWS master device adjusts the playing code stream of the playing audio data amount, maintains the adjustment parameter in the current communication data after adjusting the playing code stream, and sends the maintained adjustment parameter to the TWS slave device, that is, when the adjustment parameters all satisfy the preset condition, the maintained adjustment parameter is sent to the TWS slave device, so that the TWS slave device adjusts according to the adjustment parameter sent by the TWS master device, and the TWS master device and the TWS slave device operate under the same adjustment parameter. Specifically, the TWS master device determines whether the audio data amount is larger than the upper limit value of the data amount range or smaller than the lower limit value of the data amount range. If the TWS master equipment judges that the audio data volume is larger than the upper limit value, the TWS master equipment subtracts the upper limit value from the audio data volume, calculates to obtain a first difference value between the audio data volume and the upper limit value, divides the first difference value by the upper limit value to obtain an exceeding ratio of the audio data volume exceeding the data volume range, and improves a playing code stream for playing the audio data according to the exceeding ratio; if the audio data volume of the TWS main equipment is smaller than the lower limit value, the TWS main equipment subtracts the audio data volume from the lower limit value, calculates to obtain a second difference value between the lower limit value and the audio data volume, divides the second difference value by the lower limit value to obtain a low-out ratio of the audio data volume lower than the data volume range, and reduces the playing code stream of the audio data according to the low-out ratio. If the exceeding ratio is 10%, the TWS main equipment increases the playing code stream by 10%, namely increases the playing speed by 10%; when the lower ratio is not 10%, the TWS master device will reduce the play code stream by 10%, i.e. reduce the play speed by 10%. Specifically, referring to fig. 7, fig. 7 is a schematic diagram of a play code stream for adjusting the amount of audio data played by the TWS host device according to an embodiment of the present invention. The excessive amount of audio data in fig. 7 indicates that the amount of audio data is larger than the upper limit of the data amount range, and the small amount of audio data indicates that the amount of audio data is smaller than the upper limit of the data amount range.

In this embodiment, when the packet error rate is smaller than the error rate, it is further determined whether the audio data amount is within the preset amount range, and if the audio data amount is not within the data amount range, the TWS master device is further adjusted to play the play code stream of the audio data amount, and after the play code stream is adjusted, the adjustment parameter is reacquired and sent to the TWS slave device, so that the communication data of the TWS master device and the TWS slave device are kept consistent. The method and the device realize that the adjacent channel interference problem between the TWS master device and the TWS slave device is solved by increasing the audio data amount on the basis of the first embodiment, further reduce the data amount difference between the data received by the two sides of the TWS master device and the TWS slave device, and further improve the success rate of the adjacent channel interference solution.
