Referring to fig. 1, a first embodiment of the present invention provides a communication method for a headset including a TWS (True Wireless Stereo) headset that is charged using a charging case, and the headset is normally placed in the charging case for charging in a case where the headset is not used. The communication method comprises the following steps:
in step S10, the headset sends a first knock signal to the charging box. Specifically, a chip processor is arranged in the earphone, and communication transmission between the earphone and the charging box is controlled through the chip processor. In the process of transmitting communication to the charging box by the earphone, the earphone generally needs to send a first knock signal to determine whether a communication transmission channel between the earphone and the charging box is unblocked. After the charging box receives the first knock signal, if the charging box can receive communication, the charging box is controlled to generate a first response signal according to the first knock signal, the first response signal is transmitted and fed back to the earphone, and after the earphone receives the first response signal, the earphone determines that the charging box can transmit signals, and then the earphone starts to transmit communication to the charging box. When the earphone sends a first knock signal to the charging box, the earphone is in an initial state, the charging box generates a first response signal, and the charging box is also in the initial state at the moment. In addition to this, the headset has a data transmission state and a data reception state. Likewise, the charging box also has a data transmission state and a data reception state. It is further noted that usually a charging box is used for charging the headset, the initial state of the charging box and the headset comprising the charging state.
Step S20, the earphone receives the first response signal fed back by the charging box and switches to a data sending state according to the first response signal; the charging box generates a first response signal according to the first knock signal and switches to a data receiving state; specifically, after the earphone receives the first response signal, it is determined that the charging box can receive data, and the earphone starts to transmit data to the charging box. The earphone is switched from the initial state to the data sending state, and the charging box is switched from the initial state to the data receiving state.
In step S30, the headset transmits communication data to the charging box. Generally speaking, the headset is used for connecting an external communication device, the duration of the headset needs system upgrade, and the headset is used for transmitting an upgrade program package to the charging box. The way in which the headset connects to the external communication device includes a bluetooth connection.
In the technical scheme provided by this embodiment, when the earphone needs to transmit information to the charging box, the earphone sends a first knock signal to the charging box, the charging box generates a first response signal after receiving the first knock signal, the charging box is switched to a data receiving state after generating the first response signal, and the earphone is switched to a data transmitting state after receiving the fed back first response signal, so that the earphone can smoothly transmit communication to the charging box. Therefore, the earphone can transmit communication to the charging box in time, the condition that the earphone needs to wait when transmitting information to the charging box is avoided, the information can be ensured to be communicated in time, and the information transmission efficiency is effectively improved.
Referring to fig. 2, based on the first embodiment of the present invention, a second embodiment of the present invention is provided, and the communication method further includes:
step S40, the earphone receives a second knock signal sent by the charging box; similarly, a chip processor is also arranged in the charging box, and the charging box is controlled by the chip processor to generate a second knock signal. In the process that the earphone receives the transmission communication of the charging box, the charging box generally needs to send a second knock signal first to determine whether a communication transmission channel between the earphone and the charging box is unblocked. After the earphone receives the second knock signal, if the earphone can receive communication, the earphone generates a second response signal according to the second knock signal and feeds the second response signal back to the charging box in a transmission mode, and after the charging box receives the second response signal, the charging box determines that the earphone can transmit signals, and then the charging box starts to transmit communication data to the earphone. When the charging box sends a second knock signal to the earphone, the charging box is in an initial state, the earphone generates a second response signal, and the earphone is also in the initial state at the moment.
Step S50, the earphone generates a second answer signal according to the second knock signal, and switches to a data receiving state according to the second answer signal; the charging box is switched to a data sending state according to a second response signal fed back by the earphone; and after the charging box receives a second response signal fed back by the earphone, the charging box determines that the earphone can transmit signals, the charging box is switched to a data sending state, and the charging box starts to transmit communication data to the earphone. Namely, the charging box is switched from the initial state to the data transmitting state, and the earphone is switched from the initial state to the data receiving state.
In step S60, the headset receives the charging box transmission communication data. The communication content transmitted by the charging box to the earphone comprises the residual capacity of the charging box and can also comprise a control signal transmitted by the charging box to the earphone, such as controlling the volume. As can be seen from the above, the transmission channel used by the headset to transmit the first knock signal is different from the channel used by the headset to transmit the communication data.
The charging box can transmit communication to the headset through the step S40, the step S50, and the step S60. That is to say, among this application technical scheme the earphone can be to the box transmission communication that charges, and the box that charges also can be to earphone transmission communication, can realize the mode of two-way communication through this kind of earphone and the box that charges, has further improved the efficiency of transmission communication.
Referring to fig. 3, based on the second embodiment of the present invention, a third embodiment of the present invention is provided, and the communication method further includes:
step S70, setting the interval time of the generation of the first knock signal as a first time;
step S80, setting the interval time of the generation of the second knock signal as a second time; wherein the first time and the second time are different.
In particular, to avoid confusion of the communication transmission signal, the communication between the headset and the charging box is unidirectional. It is the headset that transmits communications to the charging box or the charging box that transmits communications to the headset. Sometimes, the earphone and the charging box need to transmit communication to each other, so that a situation that the earphone and the charging box start to transmit the knock signal at the same time may occur, which results in a blocked communication transmission channel, or the first knock signal and the second knock signal are superposed with each other to generate a non-standard knock signal, and the non-standard knock signal cannot be identified by the charging box and the earphone, so that the communication cannot be transmitted between the charging box and the earphone. Therefore, a retry mechanism is set, and in case of unsuccessful communication, the retry mechanism is started to let the charging box or the earphone restart the step of transmitting the communication. In order to avoid that the knock signal is transmitted again simultaneously between the headset and the charging box, the first knock signal and the second knock signal are generated at different times, i.e. the first time interval and the second time interval are different. For example, the first time interval is 250ms and the second time interval is 300ms, with a time difference between them, whereby the moments of initiating the transmission communication of the charging box and the headset can be well separated.
In addition, the first time interval may be greater than the second time interval, and the first time interval may also be less than the second time interval.
Referring to fig. 4, according to a fourth embodiment of the present invention, the communication method further includes:
in step S90, a window time for transmission communication is set, and if the transmission communication time between the headset and the charging box exceeds the window time, the transmission communication is terminated.
Specifically, an abnormality may occur during the communication transmission process, which may cause the communication transmission to not proceed efficiently. For example, the charging box sends a first knock signal to the headset, but the headset fails to recognize the first knock signal when receiving and recognizing the first knock signal, so that the communication flow is interrupted and cannot continue. In order to avoid a long-term interruption of communication due to an abnormality, a communication off time, i.e., a window time, is set. If the transmission communication time exceeds the window time, the communication step is actively ended. Of course, in order not to affect the transmission of large-capacity communication data, the window time is greater than the transmission time of communication data, for example, the window time is 100ms, while the transmission time of general communication data is only a few milliseconds or a dozen milliseconds.
Further, a fifth embodiment of the present invention is proposed on the basis of the fourth embodiment of the present invention. After the step of the headset transmitting communication data to the charging box, the method comprises the following steps:
the earphone and the charging box are reset to an initial state, wherein the initial state is a general connection state, and the general connection state is used for sending or receiving a knock signal. Specifically, the signal type of the knock signal is different from the transmission communication signal type, and therefore, it is necessary to transmit or receive the knock signal in a general connection state, so that the earphone and the charging box can transmit or receive the knock signal in one connection state. Meanwhile, the earphone and the charging box are reset to the universal connection state, the next communication transmission can be started, and a channel for transmitting the knock signal is smooth.
Further, the first knock signal and the first response signal each include a square wave signal formed by high and low levels. Specifically, the high and low levels form a square wave signal, such as a high level of 5v (volt) and a low level of 0 (volt), so that the high and low levels form a square wave signal. The high-low level signal forms a first knock signal and a first response signal which can be transmitted in a general connection state. The general connection state is the charging state between the charging box and the headset. Thereby avoiding the need for an additional knock signal transmission channel. Furthermore, the second knock signal and the second answer signal may also include square wave signals formed by high and low levels. The first knock signal, the first response signal, the second knock signal and the second response signal may be set to be square wave signals with the same waveform, or may be set to be square wave signals with different waveforms, such as changing the magnitude of the high and low levels, or changing the duration of the high and low levels.
Referring to fig. 5, the present invention also provides a communication method for a charging box that charges an earphone, the communication method including:
step S01, the charging box sends a second knock signal to the earphone; the charging box is also provided with a chip processor, and the communication transmission between the charging box and the earphone is controlled through the chip processor. The charging box transmits communication to the earphone, and in the process of transmitting communication to the earphone, the charging box generally needs to send a second knock signal to determine whether a communication transmission channel between the earphone and the charging box is unblocked. After the earphone receives the second knock signal, if the earphone can receive the communication, the earphone is controlled to generate a second response signal according to the second knock signal, the second response signal is transmitted and fed back to the charging box, and after the charging box receives the second response signal, the charging box determines that the earphone can transmit the signal, and then the charging box starts to transmit the communication to the earphone. When the charging box sends a second knock signal to the earphone, the charging box is in an initial state, the earphone generates a second response signal, and the earphone is also in the initial state at the moment.
Step S02, the charging box receives a second response signal fed back by the earphone and switches to a data sending state according to the second response signal; the earphone generates a second response signal according to the second knock signal and switches to a data receiving state; specifically, after receiving the second answer signal, the charging box determines that the headset can perform signal transmission, and then the charging box starts to transmit communication to the headset. Namely, the charging box is switched from the initial state to the data transmitting state, and the earphone is switched from the initial state to the data receiving state.
Step S03, the charging box transmits communication data to the headset. The communication content transmitted by the charging box to the earphone comprises the residual capacity of the charging box and can also comprise a control signal transmitted by the charging box to the earphone, such as controlling the volume.
It follows that the charging box can also transmit communications to the headset. That is to say, among this application technical scheme the earphone can be to the box transmission communication that charges, and the box that charges also can be to earphone transmission communication, can realize the mode of two-way communication through this kind of earphone and the box that charges, has further improved the efficiency of transmission communication.
