Based on the above terminal hardware structure and communication network system, the present invention provides various embodiments of the method.

The first embodiment is as follows:

the invention provides a charging control method on a charger side.

Referring to fig. 3, a schematic flow chart of a charging control method on a charger side according to a first embodiment of the present invention is shown, and the method is mainly used in a charger, and includes the steps of:

step S301, when receiving an ultrasonic signal sent by a terminal through a receiver and a loudspeaker, determining a terminal model according to the received ultrasonic signal;

specifically, in the present invention, the communication between the terminal and the charger may be achieved by ultrasonic waves. When the charger receives the ultrasonic signal sent by the terminal, the model of the terminal can be determined according to the received ultrasonic signal. Here, the model of the terminal mainly refers to the actual position of the coil of the terminal when different types of terminals are in different charging positions. The ultrasonic signals are sent by the terminal, the terminal sends the ultrasonic signals with different frequencies through the receiver and the loudspeaker respectively, so that the sending sources are distinguished, the charger can calculate the positions of the receiver and the loudspeaker respectively according to the received ultrasonic signals with different frequencies, the position relation of the receiver and the loudspeaker is further determined, as for the current terminal, the position of the common receiver is located in the middle of the top end of the terminal, and the loudspeaker is located on two sides of the bottom end of the terminal, as shown in fig. 6. Therefore, the current charging position of the terminal can be further determined by determining the position relation of the earphone and the loudspeaker. It will be understood that the charging position is defined herein as the position of the terminal relative to the charger, e.g., parallel or inclined at an angle. Meanwhile, the ultrasonic signals sent by the terminals can also carry the model information of the terminals, and the coil positions in the terminals of different models are determined, so that the charger can determine the model of the terminal by combining the charging position of the terminal and the coil position of the terminal.

Further, referring to fig. 4, in this embodiment, the step of determining the terminal model according to the received ultrasonic signal specifically includes the following steps:

step S401, recording the receiving data of the first microphone and the second microphone to the ultrasonic signal;

step S402, calculating the position relation between the earphone and the loudspeaker according to the received data to determine the charging position of the terminal;

step S403, searching a preset relation table according to the received data to determine a coil design model of the terminal;

and S404, determining the actual coil position of the terminal according to the charging position of the terminal and the coil design model.

Specifically, please refer to fig. 7, which is a hardware structure diagram of the charger according to the embodiments of the present invention, in the present invention, two microphones are disposed on the charger, and the first microphone and the second microphone are used for receiving the ultrasonic signal sent by the terminal. The received data of the ultrasonic signals sent by the two microphones to the terminal are recorded respectively, the positions of a receiver and a loudspeaker of the terminal can be calculated respectively, and then the relation between the receiver and the loudspeaker is determined so as to determine the charging position of the terminal. Fig. 9 is a schematic diagram of ultrasonic wave reception when the terminal is charged. As shown in the figure, assuming that the ultrasonic signal sent by the earphone is the first ultrasonic signal, when the position of the earphone is calculated, the position of the earphone can be calculated according to the receiving data of the first ultrasonic signal by the first microphone and the second microphone, in detail, the receiving data of the first microphone and the second microphone includes the receiving direction of the first ultrasonic signal, the boundary point where the first ultrasonic signal is received by the first microphone and the second microphone can be determined according to the receiving direction, namely the ultrasonic sending point, and then the position of the earphone relative to the charger can be determined by combining the distance between the first microphone and the second microphone. Similarly, the calculation of the speaker position can also be calculated in the same manner, and the ultrasonic signal emitted by the speaker is the second ultrasonic signal, and the specific calculation process is not illustrated here. It will be appreciated that there are typically two speakers at the bottom end of the terminal, and therefore, one of the speakers emitting ultrasonic waves, for example, the left one, may be set. After the positions of the receiver and the loudspeaker are determined, the charging position of the terminal can be determined. Meanwhile, the received data also includes a receiving time, so that the time interval of the terminal transmitting the ultrasonic wave, that is, the transmitting frequency can be determined according to the interval of receiving the ultrasonic wave signal. In the invention, terminals with different types can be preset, the ultrasonic wave transmitting frequencies are different, and coil design models of the terminals with different types are also different. The charger stores preset relation tables of different types of terminals and corresponding ultrasonic transmission frequencies, and the following table 1 is a preset relation table of the different types of terminals and the ultrasonic transmission frequencies:

TABLE 1

Terminal model	Transmission Interval/frequency (ms)
		A	2
B	4
		C	5
D	1
		……	……

Therefore, after the transmission frequency of the ultrasonic wave of the terminal is determined by receiving the data, the preset relation table can be inquired to determine the model of the terminal, and after the model of the terminal is determined, the coil design model of the terminal, namely the position of the coil in the terminal, can be determined. After the charging position of the terminal and the coil design model are determined, the charger can determine the actual position of the coil of the terminal according to the charging position of the terminal and the coil design model.

Step S302, matching the position of a charging coil in a charger for the charging according to the terminal model;

specifically, when wireless charging is performed, charging current is generated mainly by magnetic field induction between a coil in the terminal and a charger coil, so that non-contact charging can be realized, as shown in fig. 8, which is a charging schematic diagram of the terminal according to each embodiment of the present invention, and the charger 300 and the terminal can realize wireless charging without need. For magnetic induction charging, the relative position between the two coils can influence the charging efficiency, so that when wireless charging is carried out, the position of the charging coil in the charger can be adjusted according to the model of the terminal, and the magnetic field generated by the charging coil is maximized in the coil of the terminal, so that the charging efficiency is maximized. The position of the charging coil in the charger is adjustable, and in each charging process, after the terminal model is determined, the actual position of the coil of the terminal is also determined, so that the charger can match the position of the charging coil in the charger for the charging according to the terminal model, and the maximum charging efficiency of the charging is obtained.

And step S303, controlling the charging coil to be electrified so as to start charging the terminal.

Specifically, after the position of the charging coil is determined, at this time, charging can be started, and the charger controls the charging coil to be electrified to generate a changing magnetic field, so that the terminal can be charged. It is understood that the changing magnetic field may be generated by a changing current, for example, the energizing current of the charging coil may be a current with a continuously changing direction, or a current with a continuously changing magnitude, etc., which is not limited by the present invention.

Further, referring to fig. 5, in this embodiment, the step S303 specifically includes:

s501, controlling the electrifying current of the charging coil to be a first preset current so as to rapidly charge the terminal;

s502, after receiving an alarm ultrasonic signal sent by the terminal, controlling the electrifying current of the charging coil to be a second preset current;

specifically, it is assumed that the charging is started every time in a fast charging mode, and the current applied in the fast charging mode is larger than the current applied in the normal mode (protection mode). Therefore, the first predetermined current is greater than the second predetermined current. After charging is started, if the charging temperature is too high, the terminal sends an alarm ultrasonic signal to the charger, and after the signal is received, the charger reduces the electrifying current of the charging coil so as to switch the quick charging mode into a general mode. It is understood that, here, the warning ultrasonic signal may be an ultrasonic signal with a preset frequency, and is different from the first ultrasonic signal and the second ultrasonic signal which are respectively emitted by the terminal receiver and the speaker at the beginning of charging and trigger charging, and the frequencies of the warning ultrasonic signal, the first ultrasonic signal and the second ultrasonic signal are all different. The alarm ultrasonic signal may be sent by a receiver or a speaker, but the invention is not limited thereto.

Further, in this embodiment, after step S303, the method further includes the following steps:

Specifically, after charging is completed, the terminal sends a completion ultrasonic signal, and after receiving the completion ultrasonic signal, the charger controls the energization current of the charging coil to be 0, so that charging can be completed. It is understood that the alarm ultrasonic signal may also be an ultrasonic signal of a preset frequency, which is different from the first ultrasonic signal and the second ultrasonic signal which are respectively emitted by the terminal receiver and the loudspeaker at the beginning of charging and trigger charging, and the alarm ultrasonic signal. The frequencies of the completion ultrasonic signal, the alarm ultrasonic signal, the first ultrasonic signal and the second ultrasonic signal are all different. The alarm ultrasonic signal may be sent by a receiver or a speaker, but the invention is not limited thereto.

It is understood that in other embodiments, only the charging coil may be controlled not to be powered, but the charger still remains in the powered standby state, power may only be kept to the first microphone and the second microphone, while other modules, such as the charging coil, etc., remain in the dormant state (i.e., the unpowered state), when the first microphone and the second microphone receive the ultrasonic signal sent by the terminal, the charger may enter the normal powered state again, and the other modules resume power supply to restart charging the terminal. Therefore, the charger can be fixedly plugged in the socket all the time without plugging, and the operation of a user is avoided.

In the charging control method of the embodiment, when an ultrasonic signal sent by a terminal through a receiver and a loudspeaker is received, a terminal model is determined according to the received ultrasonic signal; matching the position of a charging coil in the charger for the charging according to the terminal model; and controlling the charging coil to be electrified so as to start charging the terminal. Therefore, communication is carried out between the charger and the terminal through ultrasonic signals, the terminal model is determined, and the position of the charging coil is matched for the terminal, so that intelligent charging is realized. The terminal all accessible ultrasonic wave starts wireless charging in optional position, and the user need not manual adjustment terminal locating position, also need not the manual grafting that carries out the charging wire.

in addition, the invention provides a charger. Referring to fig. 10, the charger 300 includes a processor 301, a memory 302, and a communication bus 303. Wherein the communication bus 83 is used for realizing the connection communication between the processor 301 and the memory 302, the memory 301 is a computer-readable storage medium in which a charging control program is stored, and the processor 301 can realize the following steps 1-3 by executing the computer program:

It can be understood that the charger 300 can charge one terminal or simultaneously charge a plurality of terminals, and preferably, when the charger can charge a plurality of terminals, the position adjustment of the charging coil is adjusted based on the optimal overall charging efficiency of the plurality of terminals.

By executing the charging control program of the embodiment, when receiving an ultrasonic signal sent by a terminal through a receiver and a loudspeaker, determining the terminal model according to the received ultrasonic signal; matching the position of a charging coil in the charger for the charging according to the terminal model; and controlling the charging coil to be electrified so as to start charging the terminal. Therefore, communication is carried out between the charger and the terminal through ultrasonic signals, the terminal model is determined, and the position of the charging coil is matched for the terminal, so that intelligent charging is realized. The terminal all accessible ultrasonic wave starts wireless charging in optional position, and the user need not manual adjustment terminal locating position, also need not the manual grafting that carries out the charging wire.

Example three:

the present invention further provides a computer-readable storage medium having stored thereon a charging control program that, when executed by a processor, implements the charging control method introduced in the first embodiment.

Example four:

the invention provides a terminal-side charging control method, which corresponds to the charger-side charging control method of the first embodiment.

A charging control method on a terminal side provided by a fourth embodiment of the present invention is mainly used in the terminal side, and is matched with a charging control method on a charger side to realize charging of the terminal together, and the method includes the following steps:

Specifically, the terminal charging trigger instruction may be automatically sent by the terminal through detecting the electric quantity, or may be triggered by the user. In the automatic mode, the terminal detects the current electric quantity of the terminal in real time, and when the electric quantity is less than a preset threshold value, a charging trigger instruction is sent. If the user triggers the charging trigger instruction, the user may trigger the charging trigger instruction through a preset operation, for example, pressing a preset button, or through a preset sliding gesture, and when the terminal detects the preset operation of the user, the charging trigger instruction is triggered. In the invention, the communication between the terminal and the charger can be realized by ultrasonic waves, and when the terminal detects a charging trigger instruction and determines that the terminal needs to be charged at the moment, the ultrasonic signals can be sent out by a receiver and a loudspeaker so that the charger controls the charging coil to be electrified to start charging the terminal.

Further, in this embodiment, the step of emitting the ultrasonic signal through the earpiece and the speaker specifically includes the following steps:

controlling the receiver to send out a first ultrasonic signal;

controlling the loudspeaker to emit a second ultrasonic signal;

specifically, in order to distinguish the ultrasonic signals emitted by the receiver and the speaker, the frequencies of the ultrasonic signals emitted by the receiver and the speaker are necessarily different, in this embodiment, the frequency of the first ultrasonic signal emitted by the receiver is 25kHz, and the frequency of the second ultrasonic signal emitted by the speaker is 30 kHz.

Further, because the coil design models of different types of terminals are different, the terminals of different types also need to be distinguished. In the present invention, terminals of different types may be preset, the transmission intervals/frequencies at which the terminals transmit the first ultrasonic signal/the second ultrasonic signal are also different, a preset relationship table of terminals of different types and corresponding ultrasonic transmission frequencies is stored in the charger, and the table is also stored in the terminal, and the following table 1 is a preset relationship table of terminals of different types and ultrasonic transmission frequencies:

TABLE 1

Therefore, before the ultrasonic signals are transmitted, the terminals of different models can determine the transmission frequency by inquiring the preset relation table, and then transmit the first ultrasonic signals and the second ultrasonic signals at the transmission frequency. Here, the transmission frequency refers to a transmission frequency of one of the ultrasonic frequencies, for example, a transmission frequency at which a receiver transmits a first ultrasonic wave or a transmission frequency at which a speaker transmits a second ultrasonic wave. Different signal terminals adopt different sending frequencies, and the charger can determine the model of the terminal according to the sending frequencies after receiving the ultrasonic waves.

Further, in this embodiment, the method further includes the following steps:

Specifically, it is assumed that the charging is started every time in a fast charging mode, and the current applied in the fast charging mode is larger than the current applied in the normal mode (protection mode). After the charging is started, if the charging temperature is too high, the terminal is damaged, therefore, when the charging protection function is started, the terminal can detect the current charging temperature of the terminal in real time after charging, when the temperature is higher than the warning temperature, the charging speed needs to be reduced so as to reduce the current charging temperature of the terminal, at the moment, the terminal can send an alarm ultrasonic signal to the charger, and after the signal is received, the charger can reduce the electrifying current of a charging coil so as to switch a quick charging mode to be a common mode. It is understood that, here, the warning ultrasonic signal may be an ultrasonic signal with a preset frequency, and is different from the first ultrasonic signal and the second ultrasonic signal which are respectively emitted by the terminal receiver and the speaker at the beginning of charging and trigger charging, and the frequencies of the warning ultrasonic signal, the first ultrasonic signal and the second ultrasonic signal are all different. The alarm ultrasonic signal may be sent by a receiver or a speaker, but the invention is not limited thereto. Meanwhile, the terminal also detects the current charging completion degree in real time, when the charging completion degree is detected to be 100%, namely when the charging is completed, the terminal sends a completion ultrasonic signal, and after the charger receives the signal, the electrifying current of the charging coil is controlled to be 0, so that the charging can be finished. It is understood that the alarm ultrasonic signal may also be an ultrasonic signal of a preset frequency, which is different from the first ultrasonic signal and the second ultrasonic signal which are respectively emitted by the terminal receiver and the loudspeaker at the beginning of charging and trigger charging, and the alarm ultrasonic signal. The frequencies of the completion ultrasonic signal, the alarm ultrasonic signal, the first ultrasonic signal and the second ultrasonic signal are all different. The alarm ultrasonic signal may be sent by a receiver or a speaker, but the invention is not limited thereto.

It can be understood that, when the charge protection function is in the default on state, the user may also set the function through a charge setting interface, for example, fig. 11 is a schematic view of a charge setting interface of the terminal according to various embodiments of the present invention, and the user may enter the interface to turn on or turn off the charge protection function.

In the charging control method of the embodiment, when the terminal detects the charging trigger instruction, the earphone and the speaker send out the ultrasonic signal to enable the charger to control the charging coil to be electrified to start charging the terminal. Therefore, for a user using the terminal, the terminal can realize automatic charging and intelligent control without any operation, and the user experience is improved.

A fifth embodiment of the present invention provides a charging control program. In this embodiment, the charging control program may be divided into one or more modules, and the one or more modules are stored in the memory 109 of the terminal 100 and executed by one or more processors (in this embodiment, the processor 110), so as to implement the charging control method described in the fourth embodiment.

Further, in this embodiment, the processor 109, by executing the charging control program, specifically includes the following steps to send out the ultrasonic wave signal through the earpiece and the speaker:

controlling the receiver to send out a first ultrasonic signal;

controlling the loudspeaker to emit a second ultrasonic signal;

TABLE 1

Further, in this embodiment, the processor 109 also executes the charging control program to implement the following steps:

By executing the charging control program of the embodiment, when the terminal detects a charging trigger instruction, the ultrasonic signal is sent out through the receiver and the loudspeaker so that the charger controls the charging coil to be electrified to start charging the terminal.
