The invention provides a communication method.
TWS headsets are now more and more sought after. The TWS earphone consists of a charging box and an earphone, and for the appearance integrity of the earphone, physical keys and the like for man-machine interaction are generally designed on the charging box, and the charging box transmits some key information to the earphone. Therefore, most charging boxes of TWS earphones have a function of communicating with the earphones in addition to a charging function. Because the appearance of the charging box and the earphone is involved, the contact points of the charging box and the earphone for communication are reduced to two from the original three. These two points are one for the charging box to be common to the headset and one for charging and communication. Some communication between the charging box and the earphone is independently developed, the charging and communication switching is realized through a control circuit, and some communication between the charging box and the earphone is realized through a mature chip of a third party. And operating corresponding registers according to a data manual provided by a chip manufacturer to realize the switching of charging and communication. Some chips have two communication modes, one is carrier communication with charging while communication, and the other is half-duplex operation mode only for communication. Due to the communication in the carrier mode, after data to be transmitted is coded, the coded data is loaded to the reference voltage, and the data is transmitted to the earphone by the charging box or the earphone by the single bus, so that the carrier communication is greatly influenced by charging parameters, namely charging voltage and current fluctuation, when the earphone is charged on the single bus. For example, in practical applications, some communications use only carrier communications, and some commands use both carrier communications and serial communications such as audio testing. Thus, in practical use, two situations can affect the stability of communication: when the reference voltage of the carrier is too high, the transmitted data is susceptible to interference, which may cause communication failure; when the audio data is tested, the audio data can be sent to the computer in a direct mode, and after transmission is finished, the earphone can return data to the computer in a carrier communication mode. When the earphone returns carrier data to the computer, if the charging current of the earphone is large, the voltage fluctuation on the switching single bus is large, and the data returned by the earphone to the computer may fail to communicate due to the voltage fluctuation.
In order to solve the above problem, referring to fig. 1 and 9, in an embodiment of the present invention, a method for dynamically adjusting a single-bus carrier reference voltage is provided to improve communication stability. The communication method comprises the following steps:
step S110, when the communication mode of the charging box is in a carrier communication mode, acquiring initial carrier reference voltage of the charging box;
in this embodiment, the charging box and the wireless headset may communicate with each other through a single bus, that is, the wireless headset and the charging box may communicate with each other and be charged through a single bus. Can compatible carrier communication and serial communication between box and the wireless earphone of charging, can specifically be at practical application's communication process, according to the size of communication data, select corresponding communication mode, specifically speaking, when the data bulk size of communication, when less, can adopt the carrier communication mode that the limit communication was simultaneously charged, when the data bulk is great, need use uart half-duplex communication, also be serial communication, the communication between box and the wireless earphone of preferentially realizing charging this moment, can not compatible simultaneously charge. It is understood that the carrier reference voltage of the carrier communication is output by the charging box, and as shown in fig. 1, the charging box is a charging block diagram of the charging box, the charging module 110 of the charging box itself has an internal resistance R1, the line loss resistance between the charging box and the earphone is R2, and the battery of the earphone also has an internal resistance R3. When the communication between the charging box and the wireless headset is switched from uart half-duplex communication to carrier communication, the voltage (voltage and current) (R1+ R2+ R3)) loss on the charging line is increased along with the increase of the charging current of the headset, so that the voltage on the single bus is unstable, the carrier communication is interfered, and the communication failure occurs. Since carrier communication is based on a reference voltage and data to be transmitted is loaded, the communication is less susceptible to interference when the voltage at the time of data transmission is higher than the reference voltage. As the battery voltage is closer to the charging voltage, the charging efficiency is higher, so that the general carrier communication dynamically adjusts the reference voltage of the carrier according to the battery voltage of the headset. Based on the above, when the battery voltage rises, the reference voltage on the carrier wave rises, so that the voltage difference between the reference voltage of the carrier wave communication and the voltage of the data transmission becomes smaller and smaller, and the probability that the carrier wave communication receives interference is higher along with the rise of the battery voltage, which is not favorable for the carrier wave communication. Based on this, in the present embodiment, when performing carrier communication, an initial carrier reference voltage is first acquired. The acquisition of the initial carrier reference voltage can be realized by a sampling resistor.
Step S120, when the initial carrier reference voltage is greater than the preset carrier reference voltage, adjusting the carrier reference voltage of the charging box from the initial carrier reference voltage to the preset carrier reference voltage;
in this embodiment, the predetermined carrier reference voltage may be set to a fixed value or a dynamic value, and the predetermined carrier reference voltage may be set to a value that does not affect carrier communication and satisfies charging efficiency. Specifically, a threshold V of the carrier reference voltage, that is, a predetermined carrier reference voltage, may be set in the charging box, and when the threshold V is higher than the predetermined carrier reference voltage, it is determined that carrier communication is affected. At this time, the carrier reference voltage can be adjusted, that is, the initial carrier reference voltage is adjusted to the predetermined carrier reference voltage, and the carrier reference voltage of the charging box is maintained at the predetermined carrier reference voltage in the communication process.
And S130, transmitting the data to be transmitted to the wireless earphone through the single bus and/or receiving the data to be transmitted by the wireless earphone.
In this embodiment, after the carrier reference voltage is adjusted, the charging box may send the data to be transmitted to the wireless headset through the single bus, or receive the data transmitted from the wireless headset. After the charging box completes the carrier communication, the carrier reference voltage may be adjusted back to the original voltage value V0, that is, the initial voltage value, and the carrier reference voltage is configured to be in a mode that the carrier reference voltage increases with the increase of the earphone voltage, that is, the carrier reference voltage changes with the charging voltage.
According to the invention, when the communication mode of the charging box is in the carrier communication mode, the initial carrier reference voltage of the charging box is obtained, so that when the initial carrier reference voltage is greater than the preset carrier reference voltage, the carrier reference voltage of the charging box is adjusted from the initial carrier reference voltage to the preset carrier reference voltage, and the data to be transmitted is received and/or sent. The method for dynamically adjusting the single-bus carrier reference voltage can solve the problem that when the serial port communication state is switched to the carrier communication state, the carrier reference voltage is too large, and interference is caused to the single-bus communication, and is beneficial to improving the single-bus communication stability between the wireless earphone and the charging box.
It should be noted that the charging module 110 of the charging box itself also has an internal resistance R1, the line loss resistance between the charging box and the earphone is R2, and the battery of the earphone also has an internal resistance R3. When the communication between the charging box and the wireless headset is switched from serial port communication to carrier communication, the charging current of the headset is large, and the voltage (voltage and current) (R1+ R2+ R3)) loss on the charging line is increased, so that the voltage on the plc single bus is unstable, the carrier communication is interfered, and communication failure occurs. In order to solve the above problem, referring to fig. 2 and 9, in an embodiment of the present invention, after the step of acquiring an initial carrier reference voltage of the charging box when the communication mode of the charging box is in the carrier communication mode, the communication method further includes:
and S140, when the current state of the charging box is in a power supply state, outputting a current adjusting instruction to the wireless earphone so as to control the wireless earphone to adjust the charging current to be preset current, and transmitting the data to be transmitted to the charging box through a single bus and/or receiving the data to be transmitted by the charging box.
In this embodiment, because the charging of the earphone needs to go through the stages of pre-charging, constant current charging, constant voltage charging, etc., the charging currents configured in different charging stages are often different, and in the charging process of the wireless earphone, the current charging stage can be determined according to the battery capacity of the earphone, so as to adjust the charging current in real time. For example when the earphone is put into the charging box, the electric quantity of the earphone battery storage of the wireless earphone is different, before charging, after the information interaction such as electric quantity, working state can be realized between the wireless earphone and the charging box, the charging box is enabled to supply power to the wireless earphone, the charging box and the wireless earphone are also enabled to perform handshaking communication, after the completion of handshaking, the contact between the earphone and the charging box at the moment can be determined to be good, and the charging box can be triggered to charge the wireless earphone at the moment. In the charging process, the charging box and the wireless earphone can also carry out information interaction, so that under the power supply state that the charging box charges the wireless earphone, the real-time current for charging the earphone is assumed to be I1When the earphone receives the test instruction sent by the charging box, the wireless earphone can compare the actual charging current of the current battery with the preset current. When the actual current is greater than the predetermined charging current, the charging current may be set to the predetermined current, for example, may be set to (I)1B) mA, which is a coefficient that can be set to a value that does not affect carrier communication while satisfying charging efficiency. For the wireless earphone, when the earphone receives the instruction sent by the charging box, the earphone firstly analyzes the instruction, judges the type of the instruction, and determines that the communication mode is carrier communication, namely determines that the communication mode is carrier communication
The communication mode is switched to carrier communication, the wireless earphone returns the result to the charging box after processing the data,and completing the communication between the wireless earphone and the charging box. Certainly, when the communication method is applied to the testing process of the wireless earphone, the charging box transmits the instruction to the earphone through single bus communication, and after receiving the testing result returned by the wireless earphone, the charging box can also transmit the testing result to the upper computer, so that the testing of the wireless earphone is completed. When the earphone returns the processed data to the charging box, the charging box switches the charging current to the real-time charging current I1。
Referring to fig. 3 and 9, in an embodiment, after the step of obtaining the initial carrier reference voltage of the charging box when the communication mode of the charging box is in the carrier communication mode, the communication method further includes:
and step S150, when the carrier reference voltage of the charging box is less than or equal to the preset carrier reference voltage, taking the initial carrier reference voltage of the charging box as the carrier reference voltage of the charging box.
It can be understood that, when the power of the wireless headset is low and the charging is an initial stage, for example, a constant current charging stage, although the reference voltage on the carrier is also rising when the battery voltage rises, at this time, the difference between the battery voltage of the headset and the charging voltage is large, and the voltage difference between the reference voltage of the carrier communication and the voltage of the data transmission is also large, at this time, the initial carrier reference voltage can still be used as the carrier reference voltage of the charging box, and as the battery voltage rises to be close to the charging voltage, that is, when the predetermined carrier voltage is reached, the probability that the carrier communication is interfered is larger, at this time, the reference voltage of the carrier communication can be set to the predetermined carrier voltage and maintained at the predetermined carrier voltage, so as to ensure the communication stability.
Referring to fig. 4 and 9, in an embodiment, before the step of determining the current state of the charging box when the communication mode of the charging box with the wireless headset is in the carrier communication mode, the communication method further includes:
step S161, acquiring communication requirements;
it can be understood that, after the wireless earphone is put into the charging box, the charging box can directly charge the wireless earphone after detecting that the wireless earphone is put into the charging box, or can communicate with the wireless earphone at the charging box, the wireless earphone sends earphone electric quantity information and the like to the charging box, and after sending a charging request to the charging box, the charging box determines charging current and charging voltage according to the earphone electric quantity information of the wireless earphone, and then charges, and meanwhile, in the charging process, the wireless earphone and the charging box can also charge, so as to realize information interaction in the charging process, such as a charging stage, real-time feedback of charging current and charging voltage, and the like. Or, when the two wireless headsets are paired for the first time, or the wireless headsets are paired with other mobile terminals, such as a mobile phone, a tablet computer, a smart watch, and the like, a pairing command needs to be sent to the headsets through the charging box, so that the wireless headsets enter a pairing mode or a pairing release mode. Or the program updating and upgrading of the wireless earphone can be realized through the charging box, specifically, after the program needing to be written is transmitted to the charging box through a data interface of the charging box by the upper computer, the charging box outputs the data needing to be updated and upgraded to the wireless earphone. Or, when testing the wireless earphone, for example, when performing audio test, the upper computer sends a test instruction to the charging box, the charging box transmits the received test instruction to the wireless earphone, the wireless earphone analyzes the instruction, outputs data such as audio to the charging box, and the charging box transmits the data such as audio back to the upper computer, thereby completing the test of the wireless earphone. In addition, the charging box and the wireless earphone can be communicated in a carrier communication mode, and can also be communicated in a serial communication mode. Therefore, the communication requirement between the wireless earphone and the charging box can be determined according to the working condition of the wireless earphone, the size of data to be transmitted, the application requirement and the like. Specifically, the communication requirement between the wireless headset and the charging box has at least the following:
when the wireless earphone is charged by the charging box, the data to be transmitted is small, and the communication requirement is carrier communication; when the charging box charges the wireless earphone, the data to be transmitted is large, and the communication requirement is serial port communication; the wireless earphone is not charged by the charging box (the charging box is equivalent to a storage box at the moment), and the communication requirement is serial port communication or carrier communication at the moment when the data to be transmitted is small; the wireless earphone is not charged by the charging box (the charging box is equivalent to a storage box at the moment), and the communication requirement is serial port communication or carrier communication at the moment when the data to be transmitted is small; in the process of testing the wireless earphone by the charging box, the communication requirements at the moment are serial port communication and carrier communication; and in the process that the charging box transparently transmits the program to be updated to the wireless earphone, the communication requirement at the moment is serial port communication.
And step S162, when the communication requirement is determined to comprise carrier communication, setting the communication mode of the charging box to be a carrier communication mode.
In this embodiment, when it is determined that the communication mode between the charging box and the wireless headset is the carrier communication mode, the communication chip in the charging box may be controlled to set the communication mode to carrier communication, and the communication chip in the headset is also controlled to set the communication mode to carrier communication, so that the charging box and the wireless headset are in the same communication mode, and then step S100 is performed, that is, the initial carrier reference voltage of the charging box is obtained, so that the single-bus carrier reference voltage is dynamically adjusted, and the stability of communication is improved.
Referring to fig. 5 and 9, in an embodiment, after the step of acquiring the communication requirement, the communication method further includes:
step S171, when the communication requirement is determined to include carrier communication and serial port communication, setting the communication mode of the charging box to be a serial port communication mode, and transmitting data to be transmitted to the wireless earphone through a single bus;
step S172, after the communication mode of the charging box is set to the carrier communication mode, step S100 and the subsequent steps are performed.
It is understood that only carrier communication or only serial communication may be required during communication between the charging box and the wireless headset, but in some application scenarios, such as testing the wireless headset, both carrier communication and serial communication may be required.

Referring to fig. 6 and 9, the present invention also proposes a communication method, including:
step S210, when the communication mode of the wireless earphone is in a carrier communication mode, determining the current state of the wireless earphone;
in this embodiment, the charging box and the wireless headset may communicate with each other through a single bus, that is, the wireless headset and the charging box may communicate with each other and be charged through a single bus. Can compatible carrier communication and serial communication between box and the wireless earphone of charging, can specifically be at practical application's communication process, according to the size of communication data, select corresponding communication mode, specifically speaking, when the data bulk size of communication, when less, can adopt the carrier communication mode that the limit communication was simultaneously charged, when the data bulk is great, need use uart half-duplex communication, also be serial communication, the communication between box and the wireless earphone of preferentially realizing charging this moment, can not compatible simultaneously charge. It can be understood that the carrier reference voltage of the carrier communication is output by the charging box, and as shown in fig. 1, the charging box is a charging block diagram of the charging box, the charging module of the charging box itself has an internal resistance R1, the line loss resistance between the charging box and the earphone is R2, and the battery of the earphone also has an internal resistance R3. When the communication between the charging box and the wireless headset is switched from uart half-duplex communication to carrier communication, the voltage (voltage and current) (R1+ R2+ R3)) loss on the charging line is increased along with the increase of the charging current of the headset, so that the voltage on the single bus is unstable, the carrier communication is interfered, and the communication failure occurs. Since carrier communication is based on a reference voltage and data to be transmitted is loaded, the communication is less susceptible to interference when the voltage at the time of data transmission is higher than the reference voltage. As the battery voltage is closer to the charging voltage, the charging efficiency is higher, so that the general carrier communication dynamically adjusts the reference voltage of the carrier according to the battery voltage of the headset. Based on the above, when the battery voltage rises, the reference voltage on the carrier wave rises, so that the voltage difference between the reference voltage of the carrier wave communication and the voltage of the data transmission becomes smaller and smaller, and the probability that the carrier wave communication receives interference is higher along with the rise of the battery voltage, which is not favorable for the carrier wave communication. Based on this, when performing carrier communication, the present embodiment first obtains the current charging current of the wireless headset. Wherein, the acquisition of the current charging current can be realized by a current detection circuit.
Step S220, when the current state of the wireless earphone is in a charging state, adjusting the charging current of the wireless earphone to a preset current;
in this embodiment, the predetermined current may be set to a constant value or a dynamic value, and the predetermined current may be set to a value that does not affect carrier communication and satisfies charging efficiency. Specifically, a threshold I of the charging current, that is, a predetermined current, may be set in the wireless headset, and when the charging current is higher than the predetermined current, it is determined that carrier communication is affected. At this time, the charging current can be adjusted to a predetermined current, and in the communication process, the charging current of the wireless headset is maintained at the predetermined current until the data transmission under the carrier communication is completed.
And step S230, transmitting the data to be transmitted to the charging box through the single bus, and/or receiving the data to be transmitted by the charging box.
In this embodiment, after the charging current is adjusted to the predetermined current, the wireless headset may send the data to be transmitted to the charging box through the single bus, or receive the data transmitted from the charging box. After the wireless earphone completes carrier communication, the current earphone electric quantity information of the wireless earphone can be obtained according to the electric quantity meter, the charging stage of the wireless earphone, such as a certain stage of constant voltage charging, constant current charging, trickle charging and the like, is determined according to the current earphone electric quantity information, and the preset current is adjusted back to the charging current required by the current charging stage according to the charging current required by the stage.
According to the invention, by dynamically adjusting the wireless charging current, the problem that the single-bus communication is interfered due to overlarge charging current when the serial port communication state is switched to the carrier communication state can be solved, and the improvement of the single-bus communication stability between the wireless earphone and the charging box is facilitated.
Referring to fig. 7 and 9, in an embodiment, before the step of determining the current state of the wireless headset when the communication mode of the wireless headset is in the carrier communication mode, the communication method further includes:
step S240, acquiring communication requirements of the wireless earphone;
step S250, when the communication mode including carrier communication and serial port communication is determined according to the communication requirement, the communication mode of the wireless earphone is set to be the serial port communication mode, and the data to be transmitted is transmitted to the charging box through a single bus;
step S260, the communication mode of the wireless headset is set to the carrier communication mode, and step S210 and the following steps are performed.
It is understood that only carrier communication or only serial communication may be required during communication between the charging box and the wireless headset, but in some application scenarios, such as testing the wireless headset, both carrier communication and serial communication may be required. At this time, according to a predetermined sequence, the communication chip in the charging box is controlled to switch the communication mode to serial communication, and the communication chip in the earphone is also controlled to set the communication mode to serial communication, so that under the condition that the charging box and the wireless earphone are in the same communication mode, the data to be transmitted is transmitted to the wireless earphone through the single bus, or the transmitted data to be transmitted is received through the single bus wireless earphone. After data transmission in the serial port communication mode is completed, the communication chip in the charging box is controlled to set the communication mode to carrier communication, and meanwhile the communication chip in the earphone is controlled to set the communication mode to carrier communication, so that under the condition that the charging box and the wireless earphone are in the same communication mode, data to be transmitted are transmitted to the wireless earphone through a single bus, or the transmitted data to be transmitted are received through the single bus wireless earphone.
Of course, in other embodiments, the charging box and the wireless earphone may also be controlled to be in a carrier communication mode, and after data transmission is completed, the charging box and the wireless earphone are controlled to be in a serial communication mode to complete data transmission, thereby meeting application requirements for simultaneous carrier communication and serial communication.

step S270, when the data to be transmitted is received, timing is started;
step S280, when the timing reaches a first preset time length and the data to be transmitted is not received again, the carrier reference voltage is adjusted to be the initial reference voltage.

In addition, the wireless headset needs to undergo stages of pre-charging, constant-current charging, constant-voltage charging and the like, the charging currents configured in different charging stages are often different, and the charging current can be adjusted in real time according to the current charging stage.
