All the above optional technical solutions may be combined arbitrarily to form the optional embodiments of the present disclosure, and are not described herein again.
Fig. 2 is a flowchart illustrating a wireless charging method according to an exemplary embodiment, where the wireless charging method is used in a transmitting end, as shown in fig. 2, and includes the following steps.
In step S201, the transmitting end transmits a wireless charging signal.
In the wireless charging process, the transmitting end is connected with an alternating current power supply, alternating current electric energy provided by the alternating current power supply is converted into electromagnetic energy, and the electromagnetic energy is transmitted out in a wireless charging signal mode.
In step S202, the transmitting end receives and demodulates a communication packet for identifying the communication condition of the wireless charging signal.
Consider a communication between a transmitting end and a receiving end over a wireless communication link. Because of the lack of USB data line connection, the connection status between the transmitting end and the receiving end cannot be determined according to whether the data line is connected. In order to avoid the situation that the battery of the receiving end is fully charged or the receiving end is far away from the sending end, the sending end continuously sends a wireless charging signal to the receiving end, and therefore energy waste is caused. After receiving the wireless charging signal sent by the sending end, the receiving end needs to send a communication packet for identifying the communication condition of the wireless charging signal to the sending end, the sending end demodulates the communication packet of the receiving end, if the demodulation is successful, the wireless communication link between the sending end and the receiving end is smooth, the wireless charging process is continued, otherwise, the wireless charging process is interrupted.
Here, the receiving end directly transmits not a communication packet to the transmitting end, but a communication waveform obtained by filtering the wireless charging signal by the receiving end. And after receiving the communication waveform, the sending end converts the communication waveform into a communication packet and demodulates the communication packet.
According to the regulations of the wireless communication protocol, the data packet sent from the sending end to the receiving end and the data packet sent from the receiving end to the sending end both meet the requirements. Heretofore, wireless communication protocols have specified the format of data bytes in data packets.
The format of the data bytes is defined as follows: the receiving end should transmit the data bytes using an eleven-bit asynchronous serial format. The data byte format includes a start bit, eight data bits, a parity bit, and a stop bit. The start bit is 0, the data bits are in LSB first order, and the parity bits are random. If the data byte contains an even number of bits, it means that the receiving end should set the parity bit to 1, otherwise, the receiving end should set the parity bit to 0. The stop bit is 1. FIG. 3 is a format of a data byte.
The format of the data packet sent by the receiving end to the sending end is specified as follows: referring to fig. 4, the data packet is composed of four parts, which are a random access preamble, a header, information, and a checksum, respectively. The random access preamble consists of at least eleven bits and at most twenty-five bits, all set to 1, and is encoded in a data byte format into a physical layer and a data link layer. The random access preamble enables the transmitting end to be synchronized with the input data and to accurately detect the start bit of the header. The random access preamble, header, information and check all comprise three or more data bytes.
The format of the data packet sent from the sending end to the receiving end is as follows: a data packet consists of a series of bytes and the sender should send in consecutive order, i.e. there should be no pause between two consecutive bytes. Referring to fig. 5, a data packet consists of three parts, namely a header, information and a checksum. The header, information and checksum include three or more data bytes.
Based on the prescribed data packet format, the process of demodulating the communication packet by the sending end is as follows: the sending end demodulates the received communication packet to obtain communication information, and the communication information comprises parity check bits, checksum and the like. The sending end checks the communication information according to the check sum in the communication information; and if the communication information is failed to be checked, determining that the communication packet is failed to be demodulated.
In step S203, when demodulation of at least one communication packet fails, the transmitting end adjusts a charging operation mode of a wireless charging signal to be transmitted, so as to implement stable wireless charging.
In order to realize stable wireless charging, when demodulation of at least one communication packet fails, the sending end adjusts a charging working mode of a wireless charging signal to be sent, and the following steps can be adopted:
2031. when demodulation fails for at least one of the consecutive communication packets, the transmitting end adjusts at least one of a demodulation parameter and a communication waveform.
When receiving the communication packet, the demodulation module of the sending end demodulates the received communication packet. When demodulation fails for at least one of the successive communication packets. In order to ensure that the wireless communication process is carried out smoothly, the sending end attempts to demodulate the communication packet by adjusting the demodulation parameters to change the demodulation network and the communication packet and adjusting the communication waveform to change the content of the communication packet from the perspective of adjusting the demodulation network and the communication packet.
The demodulation parameters are related parameters for demodulating the communication packet by the demodulation module, the demodulation parameters include a demodulated gain value and a demodulated reference threshold value, the gain value is a scaling multiple when the communication waveform is processed, and the reference threshold value is a related threshold value for converting the communication waveform into the communication packet. The communication waveform is an initial form before the communication packet is not processed, and is obtained by filtering the wireless charging signal, so that the communication waveform is actually determined according to the wireless charging signal sent by the sending end, and the wireless charging signal can be determined according to the energy transmission frequency of the sending end and the wired input voltage of the sending end.
Based on the content of the demodulation parameter and the decision factor of the communication waveform, when the demodulation of at least one continuous communication packet fails, the sending end may adopt the following processing modes:
In the first method, the transmitting end adjusts the gain value of demodulation.
Wherein the gain value affects the structure of the transmitting side demodulation network. Therefore, the transmitting end can attempt to decode the communication packet by increasing or decreasing the gain value of demodulation. When the signal strength of the received communication waveform is small, the gain value of demodulation can be increased; when the signal strength of the received communication waveform is large, the gain value of demodulation can be reduced.
In the second mode, the sending end adjusts the reference threshold value of demodulation.
Wherein the demodulated gain value affects the structure of the transmitting side demodulation network. Therefore, the transmitting end may increase or decrease the reference threshold for demodulation in an attempt to decode the communication packet. When adjusting the reference threshold for demodulation, the sending end may increase and decrease the reference threshold for demodulation, for example, first increase the reference threshold for demodulation, and then decrease the reference threshold for demodulation; the reference threshold for demodulation may also be determined to be increased or decreased according to different scenarios, for example, the reference threshold for demodulation is increased in the first scenario, and the reference threshold for demodulation is increased by a preset step each time; for another example, in the second scenario, the reference threshold of demodulation is reduced, and the reference threshold of demodulation is reduced by a preset step size; the adjustment may be performed according to a result of processing the communication waveform, for example, when all bytes of the communication packet obtained by processing the communication waveform are 1 or 1, the reference threshold value for demodulation may be increased by a preset step length each time, and when all bytes of the communication packet obtained by processing the communication waveform are 0 or 0, the reference threshold value for demodulation may be decreased by the preset step length.
And in the third mode, the transmitting end adjusts the energy transmission frequency of the transmitting end.
The energy transmission frequency of the sending end influences the wireless charging signal sent by the sending end, and further influences the communication waveform obtained by filtering of the receiving end. Therefore, the transmitting end can attempt to decode the communication packet by increasing or decreasing the energy transmission frequency of the transmitting end.
In the fourth mode, the sending end adjusts the wired input voltage of the sending end.
The wired input voltage of the sending end influences the wireless charging signal sent by the sending end, and further influences the communication waveform obtained by filtering of the receiving end. Thus, the transmitting end may attempt to decode the communication packet by increasing or decreasing the wired input voltage of the transmitting end.
The above-mentioned mode through adjusting the energy transmission frequency of sending end or the wired input voltage of sending end can change cycle, amplitude, waveform shape etc. of communication information to make the communication waveform that probably demodulates the failure successfully demodulate.
In addition, the above description is given by taking an example that when demodulating at least one continuous communication packet fails, the sending end adjusts a demodulation gain value, a demodulation reference threshold value, an energy transmission frequency of the sending end, or a wired input voltage as an example, in practice, since a specific reason that the sending end fails to demodulate the communication packet is unknown, the sending end may attempt demodulation by adjusting one of the demodulation gain value, the demodulation reference threshold value, the energy transmission frequency of the sending end, or the wired input voltage, and may also attempt demodulation by adjusting at least two of the demodulation gain value, the demodulation reference threshold value, the energy transmission frequency of the sending end, and the wired input voltage, and for a specific combination form thereof, the embodiment of the present disclosure is not repeated.
2302. And based on at least one item of the adjusted demodulation parameters and the adjusted communication waveform, the sending end demodulates the received communication packet.
When the sending end demodulates the received communication packet based on at least one of the adjusted demodulation parameter and the adjusted communication waveform, the method includes, but is not limited to, the following cases:
in the first case, the transmitting end adjusts the gain value of demodulation.
And based on the adjusted demodulated gain value, the sending end demodulates the received communication packet, and if the demodulation fails, the sending end continues to adjust the demodulated gain value and continues to demodulate the received communication packet based on the adjusted demodulated gain value. And if the received communication packet is successfully demodulated before the adjustment times of the demodulated gain value reach the first preset times, responding to the contents of the successfully demodulated communication packet and continuing the wireless charging process. The first preset number of times may be 2 times, 3 times, and the like, and the first preset number of times is not limited in the embodiment of the present disclosure.
In the second case, the transmitting end adjusts the reference threshold for demodulation.
And based on the adjusted demodulation reference threshold, the sending end demodulates the received communication packet, and if the demodulation fails, the sending end continues to adjust the demodulation reference threshold and continues to demodulate the received communication packet based on the adjusted demodulation reference threshold. And if the received communication packet is successfully demodulated before the adjustment times of the reference demodulation threshold reach a second preset time, responding to the contents of the successfully demodulated communication packet and continuing the wireless charging process. The second preset number may be 1, 3, and the like, and the second preset number is not limited in the embodiment of the present disclosure.
And in the third situation, the transmitting end adjusts the energy transmission frequency of the transmitting end.
Based on the adjusted energy transmission frequency of the sending end, the sending end sends an adjusted wireless charging signal to the receiving end, the receiving end receives the adjusted wireless charging signal, then carries out filtering processing on the adjusted wireless charging signal to obtain an adjusted communication waveform, and sends the adjusted communication waveform to the sending end, and when receiving the adjusted communication waveform, the sending end processes the adjusted communication waveform according to a reference threshold value of demodulation to obtain an adjusted communication packet, and then demodulates the adjusted communication packet. And if the demodulation fails, the sending end continues to adjust the energy transmission frequency of the sending end, and continues to demodulate the received communication packet based on the adjusted energy transmission frequency of the sending end. And if the adjusted communication packet is successfully demodulated before the adjustment times of the energy transmission frequency of the sending end reach a third preset time, responding to the contents of the successfully demodulated communication packet and continuing the wireless charging process. The third preset number of times may be 3 times, 4 times, and the like, and the third preset number of times is not limited in the embodiment of the present disclosure.
In the fourth case, the transmitting end adjusts the wired input voltage of the transmitting end.
Based on the adjusted wired input voltage, the sending end sends an adjusted wireless charging signal to the receiving end, the receiving end receives the adjusted wireless charging signal, the adjusted wireless charging signal is subjected to filtering processing to obtain an adjusted communication waveform, the adjusted communication waveform is sent to the sending end, and when the adjusted communication waveform is received, the sending end processes the adjusted communication waveform according to a demodulation reference threshold value to obtain an adjusted communication packet, and then the adjusted communication packet is demodulated. If the demodulation fails, the sending end continues to adjust the wired input voltage of the sending end, and continues to demodulate the received communication packet based on the adjusted wired input voltage of the sending end. And if the adjusted communication packet is successfully demodulated before the adjustment times of the wired input voltage of the sending end reach the fourth preset times, responding to the contents of the successfully demodulated communication packet and continuing the wireless charging process. The fourth preset number of times may be 2 times, 4 times, and the like, and the fourth preset number of times is not limited in the embodiment of the present disclosure.
It should be noted that the process of adjusting the demodulation parameter or the communication waveform of the demodulation and the process of demodulating the communication packet are performed simultaneously, after the demodulation parameter or the communication waveform of the demodulation is adjusted, the sending end demodulates the communication packet based on the adjusted demodulation parameter or the adjusted communication waveform, and if the demodulation fails, the process of adjusting the demodulation parameter or the communication waveform of the demodulation is continued.
In addition, in the above example, the transmitting end adjusts one of the demodulated gain value, the demodulated reference threshold value, the energy transmission frequency of the transmitting end, or the wired input voltage, and demodulates the received communication packet based on the adjusted demodulated gain value, the demodulated reference threshold value, the energy transmission frequency of the transmitting end, or the wired input voltage, in practice, the transmitting end may adjust at least two of the demodulated gain value, the demodulated reference threshold value, the energy transmission frequency of the transmitting end, and the wired input voltage, and demodulate the received communication packet based on at least two of the adjusted demodulated gain value, the demodulated reference threshold value, the energy transmission frequency of the transmitting end, and the wired input voltage.

The sending end demodulates based on the adjusted charging working mode, if the received communication packet is successfully demodulated, the content of the communication packet is responded, if the received communication packet is unsuccessfully demodulated, the sending end continues to demodulate by adopting the adjusted charging working mode, and step S205 is executed to further judge whether the wireless charging process is terminated.
In step S205, when the received communication packets are all failed to be demodulated for the preset time, the transmitting end interrupts the wireless charging process.
The preset time may be 20 seconds, 30 seconds, and the like, and the embodiment of the present disclosure does not specifically limit the preset time. When the transmitting end adjusts at least one of the demodulation parameter and the communication waveform and demodulates the received communication packet to fail in the preset time based on the adjusted at least one of the demodulation parameter and the communication waveform, the wireless communication link between the transmitting end and the receiving end is determined to be interrupted, and the transmitting end interrupts the wireless communication process to avoid energy waste.

And the sending end receives the communication packet sent by the receiving end and checks the communication packet. If the communication packet passes the verification, the content of the communication packet is correctly responded; if the verification of the communication packet fails, an attempt is made to demodulate n1 consecutive communication packets. If the demodulation of the n1 communication packets is successful, the communication packet content is correctly responded; if demodulation fails for n1 consecutive communication packets, the demodulated gain value is adjusted, and the received communication packets are demodulated based on the adjusted gain value. And if the demodulation is successful, correctly responding the content of the communication packet, and if the demodulation of the communication packet is still failed for n2 times, adjusting the energy transmission frequency of the sending end, and demodulating the received communication packet based on the adjusted energy transmission frequency of the sending end. If the demodulation is successful, the content of the communication packet is correctly responded, and if the demodulation of the communication packet is still failed due to n3 times of attempts, the communication is interrupted, and the charging to the receiving end is stopped.
According to the method provided by the embodiment of the disclosure, the communication packets for identifying the communication condition of the wireless charging signal are received and demodulated, and when demodulation of at least one communication packet fails, the charging working mode of the wireless charging signal to be sent is adjusted, so that stable wireless charging is realized.
