Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant application and are not limiting of the application. It should be noted that, for the convenience of description, only the parts related to the related applications are shown in the drawings.

Referring to fig. 1, a schematic diagram of an application scenario of a system provided in an embodiment of the present application is shown. As shown in fig. 1, in this application scenario, an electronic device 11 and a charging device 12 are included, and the charging device 12 may accommodate the electronic device 11. A battery can be integrated in the electronic device 11, and a mobile power supply is integrated in the charging device 12; in this way, after the electronic device 11 is placed in the charging device 12, if the electronic device 11 enters the charging mode, the battery in the electronic device 11 can be charged by the mobile power supply in the charging device 12.

It should be noted that the electronic device 11 may be implemented in various forms, for example, the electronic device may include a smart phone, smart glasses, Personal Digital Assistant (PDA), Portable Media Player (PMP), wearable device, TWS headset, neck headphones, wireless-by-wire headset, wireless headset, bluetooth sound box, etc.; the charging device 12 may be a charging box configured to be connected to the electronic device 11, or may also be a test fixture configured to be connected to the electronic device 11, and the embodiment of the present application is not limited in particular. Exemplarily, in fig. 1, the electronic device 11 is a TWS headset, and the charging device 12 is a charging box configured to the TWS headset.

The following description will be made of the related art by taking the electronic device 11 as a TWS headset and the charging device 12 as a charging box matched with the TWS headset as an example.

For the TWS earphone, the left and right earplugs of the TWS earphone can work independently without cable connection by realizing wireless separation of left and right sound channels. Also in TWS headsets, there are two POGO PINs (POGO PINs) at the bottom; therefore, when the TWS earphone is placed in the charging box, the circuit between the TWS earphone and the charging box can be conducted, and therefore the TWS earphone can be charged or used for communication. Currently, common POGO PINs include two PINs and three PINs, and the positions are respectively located at corresponding positions on the TWS headset and the charging box (for example, the POGO PIN in the TWS headset is placed below the earplugs); so, when the TWS earphone is placed in the box that charges, POGO PIN in the TWS earphone and POGO PIN in the box that charges can just contact and make the circuit switch on to the charging and the communication that have realized charging box and TWS earphone use.

In the current scheme, a charging mode and a communication mode between a charging box and a TWS earphone cannot work simultaneously; that is, during the charging process, communication cannot be performed simultaneously, i.e., only charging or communication can be performed at the same time.

The embodiment of the application provides a communication method which is applied to charging equipment. The method comprises the steps of acquiring first communication information, wherein the first communication information comprises first communication content transmitted to electronic equipment by charging equipment; coding the first communication information to obtain a first modulation signal; modulating the charging voltage signal by using a first modulation signal to obtain a first modulation voltage signal; providing a first modulated voltage signal to the electronic device; therefore, the first modulation voltage signal comprises the first communication content and the charging voltage signal, and the charging voltage signal is a voltage signal output by the charging equipment when the charging equipment charges the electronic equipment, so that the charging and communication between the charging equipment and the electronic equipment can work simultaneously; and the communication between the charging equipment and the electronic equipment (such as detecting whether the electronic equipment enters a box or not, the charging state of the electronic equipment and the like) can be realized without adding extra devices, so that the cost can be reduced, the reliability of the product can be improved, and the utilization rate of the equipment is improved.

Embodiments of the present application will be described in detail below with reference to the accompanying drawings.

In an embodiment of the present application, referring to fig. 2, a flowchart of a communication method provided in the embodiment of the present application is shown. As shown in fig. 2, the method may include:

s201: acquiring first communication information; the first communication information comprises first communication content transmitted to the electronic equipment by the charging equipment;

it should be noted that the communication method is applied to the charging device. Wherein, the electronic device (such as the TWS earphone) can be built in the charging device (such as a charging box configured by the TWS earphone), and then the charging device charges the electronic device.

It should be noted that, during the process of charging the electronic device by the charging device, interactive communication is performed between the charging device and the electronic device. On one hand, the charging device can transmit communication content to the electronic device, and on the other hand, the electronic device can also transmit communication content to the charging device, so that communication between the charging device and the electronic device is achieved.

Specifically, when the charging device needs to determine the box entering state of the electronic device, the charging device may send first communication information to the electronic device, and then, based on a response of the electronic device to the first communication information, the charging device may receive a first response signal fed back by the electronic device, and may determine whether the electronic device enters the box according to the first response signal; or when the charging device needs to determine the electric quantity state of the electronic device, the charging device may also send the first communication information to the electronic device, and then based on a response of the electronic device to the first communication information, the charging device may receive a first response signal fed back by the electronic device, and according to the first response signal, the charging device may also determine the electric quantity of the electronic device; that is, the first communication information may be information for sending a communication request to the electronic device to determine a relevant state of the electronic device (such as a box-in state, a charging state, or a power state); in addition, the first communication information may also be related to sending the charging device itself to the electronic device, for example, the charging device actively sends its charging state (including a charging start state and a charging stop state) to the electronic device; here, the first communication information is specifically set according to an actual scene and a user requirement, and the embodiment of the present application is not limited at all.

S202: coding the first communication information to obtain a first modulation signal;

it should be noted that after the first communication information is acquired, the first communication information may be encoded to obtain a first modulation signal. Here, the first modulation signal may be a square wave signal (or referred to as a pulse signal), or may be other signals, such as a sine wave signal, a triangular wave signal, or the like; the first modulation signal may be a square wave signal, but the embodiment of the present application is not limited in any way.

It should be further noted that, in order to avoid that the amplitude of the first modulation signal is too large, which results in low charging efficiency, and to avoid that the amplitude of the first modulation signal is too small and the interference resistance is weak, which results in that the electronic device cannot demodulate the first modulation signal; it is generally desirable to have the amplitude of the first modulation signal within a preset amplitude range. Therefore, in some embodiments, for S202, the encoding the first communication information to obtain a first modulated signal may include:

generating a square wave signal by using the first communication information;

judging whether the amplitude of the square wave signal meets a preset amplitude range or not;

if the judgment result is yes, determining the square wave signal as the first modulation signal;

if the judgment result is negative, amplitude adjustment is carried out on the square wave signal, and the square wave signal after adjustment is determined to be the first modulation signal.

That is, after the square wave signal is generated according to the first communication information, whether the amplitude of the square wave signal meets a preset amplitude range can be judged; if the amplitude of the square wave signal meets the preset amplitude range, the square wave signal can be directly determined as a first modulation signal; if the amplitude of the square wave signal does not meet the preset amplitude range, amplitude adjustment can be performed on the square wave signal so that the adjusted square wave signal meets the preset amplitude range, and then the adjusted square wave signal is determined as the first modulation signal.

Further, in some embodiments, the amplitude adjusting the square wave signal and determining the adjusted square wave signal as the first modulation signal may include:

amplitude adjustment is carried out on the square wave signal by utilizing a voltage dividing resistor to obtain an adjusted square wave signal; determining the adjusted square wave signal as the first modulation signal.

Here, the preset amplitude range represents a preset signal amplitude range, and may be used as a measure for determining whether the amplitude of the first modulation signal needs to be adjusted. When the amplitude of the square wave signal is too large and does not meet the preset amplitude range, in order to improve the charging efficiency, the amplitude of the square wave signal can be adjusted by using the voltage dividing resistor, that is, the amplitude of the square wave signal is reduced, so that the adjusted square wave signal meets the preset amplitude range. In the embodiment of the application, the amplitude of the square wave signal can be reduced by dividing the voltage through the voltage dividing resistor, so that the amplitude of the square wave signal can be adjusted, but the embodiment of the application is not limited.

S203: modulating the charging voltage signal by using the first modulation signal to obtain a first modulation voltage signal;

the charging voltage signal is a voltage signal output when the charging device charges the electronic device. Here, the charging voltage signal is modulated by the first modulation signal, so that the charging and the communication of the charging equipment can be simultaneously carried out; that is to say, in the process that the charging equipment charges the electronic equipment, the charging mode and the communication mode can be ensured to work simultaneously.

It should be further noted that, for S203, the modulating the charging voltage signal by using the first modulation signal to obtain a first modulation voltage signal may include:

and superposing the first modulation signal and the charging voltage signal to obtain the first modulation voltage signal.

In the embodiment of the application, the modulation modes are various and can be divided into an analog modulation method and a digital modulation mode; the analog modulation method may include amplitude modulation and frequency modulation, and the digital modulation method may include amplitude keying, frequency shift keying, phase shift keying, quadrature amplitude modulation, and the like. Here, the modulation method may be specifically set according to an actual scene and a user requirement, and the embodiment of the present application is not limited at all.

Specifically, taking amplitude modulation as an example, after the first modulation signal and the charging voltage signal are obtained, the first modulation signal and the charging voltage signal may be subjected to superposition processing, so that modulation of the charging voltage signal by the first modulation signal is also achieved.

It will be appreciated that the charging voltage signal may be provided by the output power module. As shown in fig. 3, the charging device may include an output power module 301, a first resistor R1, and a second resistor R2. Wherein, the output power module can output a charging voltage signal (denoted by Vout). In this hardware circuit, the voltage at the FeedBack (FB) pin is denoted by Verf, and Vout ═ 1+ R1/R2) × Vref; the first modulation signal may be superimposed at the FB pin at this time. According to the internal structure of the output power supply module 301, a dc bias is provided at the FB pin, and then the first modulation signal is superimposed on the FB pin, so that the first communication information can be superimposed on the Vout charging voltage signal, thereby realizing simultaneous charging and communication.

Exemplarily, as shown in fig. 4A, it shows a waveform example of the charging voltage signal (denoted by Vout); here, Vout is a constant voltage value; as shown in fig. 4B, it shows a waveform example of the first modulation signal, here, the first modulation signal is a square wave signal; as such, when the first modulation signal is superimposed at the FB pin, as shown in fig. 4C, it shows a waveform example of the first modulation voltage signal, that is, a waveform example of the modulated charging voltage signal. As can be seen from fig. 4C, the charging voltage signal Vout output after superimposing the first modulation signal has a superimposed first modulation signal; after receiving the signal, the subsequent electronic equipment demodulates the signal to obtain a first communication signal; thus, communication can be performed while charging is performed.

It will also be appreciated that the modulation module may include a modulation capacitor. As shown in fig. 5A, the charging device may further include a first processor 302 and a modulation capacitor C1 based on the hardware circuit shown in fig. 3. The first processor 302 is configured to generate a square wave signal according to the first communication signal, and then superimpose the first modulation signal onto the FB pin through the adjustment capacitor C1, so that the first modulation signal is loaded onto the charging voltage signal Vout; in fig. 5A, the adjustment module may include only the modulation capacitor C1.

Further, to avoid that the charging efficiency is low due to the too large amplitude of the first modulation signal on the charging voltage signal Vout, and to avoid that the electronic device cannot demodulate the first modulation signal due to the too small amplitude and the weak anti-interference capability of the first modulation signal; the first modulated signal may be amplitude adjusted at this time. As shown in fig. 5B, the charging device may further include a third resistor R3 and a fourth resistor R4 based on the hardware circuit shown in fig. 5A. The square wave signal output by the first processor 302 can be amplitude-adjusted according to the third resistor R3 and the fourth resistor R4, so as to achieve amplitude adjustment of the first modulation signal. In fig. 5B, the modulation module may include a modulation capacitor C1, a third resistor R3, and a fourth resistor R4.

In this way, both with the hardware circuit shown in fig. 5A and with the hardware circuit shown in fig. 5B, it is possible to modulate the charging voltage signal with the first modulation signal, and obtain the first modulation voltage signal.

S204: providing a first modulated voltage signal to the electronic device; wherein the first modulated voltage signal includes the first communication content and the charging voltage signal.

Thus, after obtaining the first modulated voltage signal, the first modulated voltage signal may be provided to the electronic device; the electronic device is convenient to demodulate the first modulation voltage signal, so that the electronic device can obtain the first communication information transmitted by the charging device.

In some embodiments, after S204, the method may further include:

receiving a first response signal generated and sent by the electronic equipment according to first communication content in the first modulation voltage signal;

determining a state of the electronic device based on the first response signal; wherein the state of the electronic device comprises at least one of: the in-box state of the electronic device, the electric quantity state of the electronic device and the charging state of the electronic device.

It should be noted that, after the charging device provides the first modulation voltage signal to the electronic device, the electronic device may demodulate the first modulation voltage signal to obtain the first communication information transmitted by the charging device; the electronic device may then send a first reply signal to the charging device; at this time, the charging device can receive the first response signal sent by the electronic device, and can determine the state of the electronic device according to the first response signal.

The state of the electronic equipment can be a box-in state of the electronic equipment and is used for determining whether the electronic equipment is placed in a box; or the power state of the electronic device, and is used for determining the power of the electronic device, determining whether the power of the electronic device is full, and the like; the charging state of the electronic device may also be used to determine whether the electronic device continues to be charged or is charged to an end, and the like. Therefore, the first modulation signal is superposed on the charging voltage signal, so that communication can be simultaneously carried out in the charging process.

Referring to fig. 6, a schematic diagram of a composition structure of a charging device provided in an embodiment of the present application is shown. As shown in fig. 6, the charging device may include a first processor 601, an indication module 602, a power supply module 603, an output power module 604, and a modulation module 605; the first processor 601 serves as a control center of the charging device, is connected with each part of the charging device, and executes various functions and processing data of the charging device to realize overall monitoring of the charging device; the indication module 602 is configured to indicate or display information input by a user or information provided to the user, so as to determine various states of the charging device; the power supply module 603 is used for supplying power to the first processor 601, and can also charge the charging device by an external power supply; the output power module 604 is used for the charging device to provide a charging voltage signal to the electronic device, and the output power module 604 may be a Direct Current-Direct Current (DC-DC) conversion module; the modulation module 605 is configured to modulate the first communication information to be transmitted into the output power module to obtain a first modulation voltage signal; and then the electronic equipment analyzes the first modulation voltage signal after receiving the first modulation voltage signal, so that the charging and the communication can be carried out simultaneously. That is, a first modulation signal (such as a square wave signal) is superimposed on the charging voltage signal, and specifically, as shown in fig. 3, the first modulation signal may be superimposed at the FB pin of the output power module, so that the signal is loaded into the output power module, and charging and communication can be performed simultaneously.

The embodiment provides a communication method applied to charging equipment. Acquiring first communication information; the first communication information comprises first communication content transmitted to the electronic equipment by the charging equipment; coding the first communication information to obtain a first modulation signal; modulating the charging voltage signal by using a first modulation signal to obtain a first modulation voltage signal; providing a first modulated voltage signal to the electronic device; therefore, the first modulation voltage signal comprises the first communication content and the charging voltage signal, and the charging voltage signal is a voltage signal provided by the charging equipment when the charging equipment charges the electronic equipment, so that the charging and communication between the charging equipment and the electronic equipment can work simultaneously; and the communication between the charging equipment and the electronic equipment can be realized without adding extra devices, so that the cost can be reduced, the reliability of the product can be improved, and the utilization rate of the equipment is improved.

Further, in some embodiments, referring to fig. 7, a detailed flowchart of a communication method provided in the embodiments of the present application is shown. As shown in fig. 7, when applied to a charging device, the detailed process may include:

s701: detecting whether the charging equipment is opened;

s702: when the charging equipment is in an uncapped state, controlling the charging equipment to output a charging voltage signal;

it should be noted that, for whether the electronic device is loaded into the box, that is, whether the electronic device is inside the charging device is determined, it is first necessary to control the charging device to output a charging voltage signal. Generally speaking, when the charging device is detected to be in the uncapped state, the charging device may be controlled to output a charging voltage signal at this time to charge the electronic device; however, other processing manners are also possible, such as controlling the charging device to output a charging voltage signal to charge the electronic device when the distance between the electronic device and the charging device satisfies a preset distance threshold; the embodiments of the present application are not particularly limited.

S703: acquiring first communication information;

s704: coding the first communication information to obtain a first modulation signal;

it should be noted that the first modulation signal and the output charging voltage signal may be output simultaneously, or the first modulation signal may be output first, and then the charging voltage signal is output; or the charging voltage signal is output first, and then the first modulation signal is output; that is, both steps S701 to S702 and steps S703 to S704 may be output in parallel or may be output in series to obtain the charging voltage signal and the first modulation signal.

S705: modulating the charging voltage signal by using a first modulation signal to obtain a first modulation voltage signal;

s706: providing the first modulated voltage signal to the electronic device;

it should be noted that, after the charging voltage signal and the first modulation signal are acquired, the charging voltage signal may be modulated by the first modulation signal, so as to obtain a first modulation voltage signal. Specifically, the first modulation signal and the charging voltage signal may be superimposed, so that the first modulation signal modulates the charging voltage signal, and then the modulated first modulation voltage signal is sent to the electronic device, so that the subsequent electronic device demodulates the signal to obtain the first communication information transmitted by the charging device, and the electronic device also sends the first response signal to the charging device.

S707: receiving a first response signal generated and sent by the electronic equipment according to first communication content in the first modulation voltage signal;

s708: determining a state of the electronic device based on the first reply signal.

Here, the charging device may determine a state of the electronic device, such as a box-in state of the electronic device, a power state of the electronic device, a charging state of the electronic device, and the like, according to the first reply signal transmitted by the electronic device after receiving the first reply signal.

In addition, if it is determined that the electronic equipment is not loaded into the box, the charging equipment is empty at this time, and the charging equipment can output charging voltage signals at intervals according to a preset period, so that power consumption can be saved; when it is determined that the electronic device is placed in the box, the electronic device is placed in the charging device, and the charging device needs to output a charging voltage signal all the time, so that the electronic device is charged on one hand, and interactive communication can be performed between the electronic device and the charging device on the other hand.

The embodiment provides a communication method applied to charging equipment. The specific implementation of the foregoing embodiment is explained in detail through this embodiment, and it can be seen that the charging and communication between the charging device and the electronic device are implemented simultaneously; and the communication between the charging equipment and the electronic equipment can be realized without adding extra devices, so that the cost can be reduced, the reliability of the product can be improved, and the utilization rate of the equipment is improved.

In another embodiment of the present application, referring to fig. 8, a flowchart of another communication method provided in the embodiment of the present application is shown. As shown in fig. 8, the method may include:

s801: receiving a first modulation voltage signal provided by a charging device, and charging based on the first modulation voltage signal;

it should be noted that the communication method is applied to electronic equipment. Wherein, the electronic device (such as the TWS earphone) can be built in the charging device (such as a charging box configured by the TWS earphone), and then the charging device charges the electronic device.

In this way, in the process that the charging equipment charges the electronic equipment, when the charging equipment sends the first communication information to be transmitted to the electronic equipment, the first communication information and the charging voltage signal are modulated on the charging equipment side at this time to obtain a first modulated voltage signal, and then the first modulated voltage signal is sent to the electronic equipment by the charging equipment; therefore, on the electronic equipment side, the first modulation voltage signal can be received to analyze the first communication information, and on the other hand, charging can be performed according to the first modulation voltage signal.

S802: demodulating the first modulation voltage signal to obtain a first demodulation signal;

it should be noted that demodulation is a process of recovering information from a modulated signal carrying information. In various information transmission or processing systems, a transmitting end (such as a charging device) modulates a carrier wave with information to be transmitted to generate a signal carrying the information; the receiving end (e.g., electronic device) then needs to recover the carried information, which is demodulation.

In particular, demodulation is the inverse of modulation. The modulation method is different, and the demodulation method is also different. The demodulation method can be classified into sine wave demodulation (also referred to as continuous wave demodulation) and pulse wave demodulation, corresponding to the classification of the modulation method. The sine wave demodulation can be further divided into amplitude demodulation, frequency demodulation, phase demodulation, and the like, and some variant demodulation modes, such as single sideband signal demodulation, vestigial sideband signal demodulation, and the like. Also, pulse wave demodulation can be classified into pulse amplitude demodulation, pulse phase demodulation, pulse width demodulation, pulse code demodulation, and the like. Here, the demodulation method may be specifically set according to an actual scene and a user requirement, and the embodiment of the present application is not limited at all.

In some embodiments, for S802, the demodulating the first modulated voltage signal to obtain a first demodulated signal may include:

analyzing the first modulation voltage signal through a blocking capacitor device to obtain a square wave signal;

determining the square wave signal as the first demodulated signal.

It should be noted that the square wave signal can be resolved from the first modulation voltage signal by using the demodulation module. The demodulation module may include a demodulation capacitor (alternatively referred to as a dc blocking capacitor), which is mainly used to isolate dc, and may resolve the modulated square wave signal from the first modulation voltage signal.

It will be appreciated that the modulation module may include a modulation capacitor. As shown in fig. 9A, the electronic device may include a charging module 901, a second processor 902, and a demodulation capacitor C2. On the electronic device side, the received first modulation voltage signal is denoted by Vcharger, and the waveform of the first modulation voltage signal is shown in fig. 4C; here, the first modulated voltage signal enters the charging module 901 to charge the battery in the electronic device, and passes through the demodulation capacitor C2 to resolve a first demodulated signal (i.e., a square wave signal), the waveform of which is shown in fig. 10A; the resolved square wave signal is then sent to the second processor 902 so that the second processor 902 can identify the first communication information sent by the charging device.

Further, after the square wave signal is analyzed, in order to avoid the amplitude of the square wave signal being too small or too large, the amplitude of the square wave signal can be adjusted. Thus, in some embodiments, the determining the square wave signal as the first demodulated signal may include:

if the judgment result is yes, determining the square wave signal as the first demodulation signal;

if the judgment result is negative, amplitude adjustment is carried out on the square wave signal, and the square wave signal after adjustment is determined to be the first demodulation signal.

That is, after the square wave signal is analyzed, whether the amplitude of the square wave signal meets the preset amplitude range can be further judged; if the amplitude of the square wave signal meets the preset amplitude range, the square wave signal can be directly determined as a first demodulation signal; if the amplitude of the square wave signal does not satisfy the preset amplitude range, amplitude adjustment may be performed on the square wave signal so that the adjusted square wave signal satisfies the preset amplitude range, and then the adjusted square wave signal is determined as the first demodulation signal.

Further, in some embodiments, the amplitude adjusting the square wave signal and determining the adjusted square wave signal as the first demodulation signal may include:

utilizing an amplifier to carry out amplitude adjustment on the square wave signal so as to obtain an adjusted square wave signal; determining the adjusted square wave signal as the first demodulation signal.

Here, the preset amplitude range represents a preset signal amplitude range, and may be used as a measure for determining whether the amplitude of the first demodulation signal needs to be adjusted. When the amplitude of the square wave signal is too small and does not satisfy the preset amplitude range, in order to improve the recognition degree of the electronic device on the demodulated signal, amplitude adjustment may be performed on the square wave signal, for example, the amplitude of the square wave signal is increased, so that the adjusted square wave signal satisfies the preset amplitude range. In the embodiment of the present application, the amplitude of the square wave signal may be increased by an amplifier, so that the amplitude adjustment of the square wave signal may be achieved, but the embodiment of the present application is not limited.

It is understood that the amplitude of the square wave signal may be adjusted at this time in order to avoid the electronic device from being unable to recognize the demodulated signal due to the too small amplitude of the square wave signal. As shown in fig. 9B, the electronic device may further include an amplifier 903 on the basis of the hardware circuit shown in fig. 9A; after the square wave signal is obtained through the demodulation capacitor C1, the square wave signal may be further amplitude-adjusted according to the amplifier 903 to increase the amplitude of the square wave signal, and then sent to the second processor 902. Here, as shown in fig. 10B, it shows an example of a waveform of an amplitude-amplified square wave signal, and the amplified signal is helpful for information identification, that is, the first communication information transmitted by the charging device can be identified more conveniently and accurately.

S803: and decoding the first demodulation signal to obtain first communication information.

It should be noted that, after obtaining the first demodulated signal, the first demodulated signal may be sent to the second processor; the second processor then performs correlation processing, such as decoding, on the first demodulated signal, so as to identify the first communication information transmitted by the charging device.

In some embodiments, after S803, the method may further include:

generating a first response signal based on the first communication information;

transmitting the first response signal to the charging device.

It should be noted that, after the electronic device obtains the first communication information, the electronic device may further generate a first response signal and send the first response signal to the charging device, so that the charging device can know a relevant state of the electronic device, such as a box entering state of the electronic device, to determine whether the electronic device enters the box; or the electric quantity state of the electronic equipment to determine the electric quantity of the electronic equipment and whether the electric quantity is full; or the charging state of the electronic equipment to determine whether the electronic equipment continues to be charged or is charged, and the like, so that the communication between the charging equipment and the electronic equipment can be better realized.

Referring to fig. 11, a schematic diagram of a composition structure of an electronic device provided in an embodiment of the present application is shown. As shown in fig. 11, the electronic device may include a second processor 1101, a parsing module 1102, a power module 1103, and a sound emitting module 1104. The second processor 1101 is used as a control center of the electronic device, is connected to each part of the electronic device, and executes various functions and processes data of the electronic device, so as to realize overall monitoring of the electronic device; the second processor 1101 may further include a bluetooth chip, and may be configured to perform bluetooth data transmission, etc.; the analyzing module 1102 is configured to perform signal analysis to determine first communication information transmitted by the charging device; the power module 1103 is configured to provide power to the second processor 1101, and on the other hand, the power module 1103 may further include a charging module capable of charging an electronic device; the sound generation module 1104 may include a speaker that can be used to output sound signals. Thus, after the first modulation voltage signal carrying the first communication information to be transmitted is received by the power module 1103, the first modulation voltage signal can be demodulated by the parsing module 1102, and then the first modulation voltage signal is subjected to related processing by the second processor 1101 to obtain the first communication information; and the charging voltage signal in the first modulation voltage signal can charge the electronic equipment, so that the charging and the communication can be carried out simultaneously. That is to say, the modulation signal carried in the process of charging the electronic device by the charging device is demodulated, so that charging and communication can be realized at the same time.

The embodiment provides a communication method applied to electronic equipment. The method comprises the steps that a first modulation voltage signal provided by charging equipment is received, and charging is carried out based on the first modulation voltage signal; demodulating the first modulation voltage signal to obtain a first demodulation signal; decoding the first demodulation signal to obtain first communication information; therefore, the charging and communication between the charging equipment and the electronic equipment can be realized simultaneously; and the communication between the charging equipment and the electronic equipment (such as detecting whether the electronic equipment enters a box or not, the charging state of the electronic equipment and the like) can be realized without adding extra devices, so that the cost can be reduced, the reliability of the product can be improved, and the utilization rate of the equipment is improved.

Further, in addition to the charging device encoding and modulating the communication information, the embodiment of the present application may also perform signal encoding and modulating processing on the communication by the electronic device, and then transmit the obtained second modulation voltage signal to the charging device, and perform signal demodulation by the charging device, which will be described in detail below.

In another embodiment of the present application, refer to fig. 12, which shows a flowchart of another communication method provided in the embodiment of the present application. As shown in fig. 12, applied to an electronic device, the method may include:

s1201: acquiring second communication information; the second communication information comprises second communication content transmitted to the charging equipment by the electronic equipment;

s1202: coding the second communication information to obtain a second modulation signal;

s1203: modulating the charging voltage signal received by the electronic equipment by using the second modulation signal to obtain a second modulation voltage signal;

s1204: feeding back the second modulation voltage signal to the charging device, wherein the second modulation voltage signal includes the second communication content and the charging voltage signal.

It should be noted that the communication method is still applied to the electronic device. When the electronic device sends the second communication information to be transmitted to the charging device, the electronic device can encode and modulate the second communication information, then send the obtained second modulation voltage signal to the charging device, and then the charging device demodulates the second modulation voltage signal.

It should be noted that the execution subject of steps S1201 to S1204 is an electronic device, and the execution subject of steps S201 to S204 is a charging device; however, the embodiments in steps S1201 to S1204 are similar to those in steps S201 to S204, and will not be described in detail here.

Further, before S1203, the method may further include:

and when the charging equipment is in an uncapped state, receiving a charging voltage signal sent by the charging equipment.

It should be noted that, when it is detected that the charging device is in the open-cover state, the charging device may be controlled to output the charging voltage signal at this time, so that the electronic device may receive the charging voltage signal output by the charging device and perform charging according to the charging voltage signal.

In this way, after the charging voltage signal and the second modulation signal are acquired, the charging voltage signal may be modulated with the first modulation signal, thereby obtaining the second modulation voltage signal. Specifically, the second modulation signal and the charging voltage signal may be superimposed, so that the second modulation signal modulates the charging voltage signal, and then the second modulation voltage signal obtained after modulation is sent to the charging device, so that the subsequent charging device demodulates the second modulation voltage signal to obtain the second communication information transmitted by the electronic device, and the charging device also sends a second response signal to the electronic device.

In some embodiments, after S1204, the method may further include:

receiving a second response signal sent by the charging equipment;

determining a state of the charging device based on the second answer signal; wherein the state of the charging device includes at least one of: the cover opening state of the charging device, the charging state of the charging device and the box entering state of the electronic device.

It should be noted that, after the electronic device provides the second modulation voltage signal to the charging device, the charging device may demodulate the second modulation voltage signal to obtain the second communication information transmitted by the electronic device; the charging device may then send a second reply signal to the electronic device; at this time, the electronic device can receive the second response signal sent by the charging device, and then can determine the state of the charging device according to the second response signal.

Further, when the charging device does not output the charging voltage signal, the electric quantity of the electronic device is fully charged at this time, or the charging device is in a no-electric quantity state; at this time, the electronic device may directly feed back the second modulation signal as the second modulation voltage signal to the charging device after obtaining the second modulation signal. Thus, in some embodiments, after S1202, the method may further include:

determining the second modulation signal as a second modulation voltage signal when the charging device is not outputting a charging voltage signal;

and feeding back the second modulation voltage signal to the charging equipment.

It should be noted that, when the charging device does not output the charging voltage signal, the charging voltage signal (such as Vcharger signal) received by the electronic device at this time has no power; after the electronic device obtains a second modulation signal according to the second communication information, the second modulation signal can be modulated to the Vcharger end through the modulation capacitor and fed back to the charging device; then, the charging device performs demodulation processing, and the charging device can obtain the second communication information sent by the electronic device, so that the information on the electronic device side can be transmitted to the charging device side.

It should be further noted that, the electronic device may first determine whether the charging device outputs the charging voltage signal, so that, when the charging device outputs the charging voltage signal, steps S1203 and S1204 may be executed, that is, the charging voltage signal received by the electronic device is modulated by using the second modulation signal to obtain a second modulation voltage signal, and then the second modulation voltage signal is fed back to the charging device; when the charging device does not output the charging voltage signal, the second modulation signal can be directly determined to be the second modulation voltage signal, and then the second modulation voltage signal is fed back to the charging device.

That is, the second modulation signal may or may not have a dc level on the Vcharger signal when the electronic device provides the modulation signal. Specifically, taking the hardware circuit shown in fig. 9A or 9B as an example, the demodulation capacitor C2 can be regarded as a modulation capacitor at this time. When the charging device does not output a charging voltage signal, no power is applied to the Vcharger signal at this time, that is, no direct current level is applied to the Vcharger signal; at this time, the waveforms of the second modulation signal before modulating the capacitor and the second modulation voltage signal after modulating the capacitor are the same, as shown in fig. 13A; when the charging device outputs a charging voltage signal, the Vcharger signal is electrified at the moment, namely the Vcharger signal has a direct current level; at this time, the waveforms of the second modulation signal before modulating the capacitor and the second modulation voltage signal after modulating the capacitor are different, the second modulation signal before modulating the capacitor is a square wave signal, and the second modulation voltage signal after modulating the capacitor is obtained by superimposing the modulation signal on a direct current level, as shown in fig. 13B; in this way, after the second modulated voltage signal is obtained, it can be fed back to the charging device and then interpreted by the charging device.

The embodiment provides a communication method applied to electronic equipment. The specific implementation of the foregoing embodiment is explained in detail through this embodiment, and it can be seen that, since the second modulation voltage signal is obtained by modulating the charging voltage signal by using the second modulation signal, and the charging voltage signal represents a voltage signal provided by the charging device when the charging device charges the electronic device, the charging and communication between the charging device and the electronic device can be simultaneously performed; and the communication between the charging equipment and the electronic equipment can be realized without adding extra devices, so that the cost can be reduced, the reliability of the product can be improved, and the utilization rate of the equipment is improved.

In yet another embodiment of the present application, referring to fig. 14, a flowchart of another communication method provided in the embodiment of the present application is shown. As shown in fig. 14, applying the charging device, the method may include:

s1401: receiving a second modulation voltage signal sent by the electronic equipment;

s1402: demodulating the second modulation voltage signal to obtain a second demodulation signal;

s1403: decoding the second demodulation signal to obtain second communication information; the second communication information comprises second communication content transmitted to the charging equipment by the electronic equipment.

It should be noted that the communication method is applied to the charging device. Here, when the electronic device sends the second communication information to be transmitted to the charging device, the electronic device encodes and modulates the second communication information at this time, and then sends the obtained second modulated voltage signal to the charging device; after the charging device receives the second modulated voltage signal, it may be signal demodulated by the charging device.

It is to be noted that the execution subject of steps S1401 to S1403 is a charging device, and the execution subject of steps S801 to S803 is an electronic device; however, the embodiments of steps S1401 to S1403 are similar to those of steps S801 to S803, and are not described in detail here.

In this way, after the electronic device acquires the second communication information, the electronic device may perform encoding and modulation processing on the second communication information to obtain a second modulation voltage signal; the electronic device then transmits the second modulated voltage signal to the charging device. After the charging device receives the second modulation voltage signal sent by the electronic device, the second modulation voltage signal can be demodulated to obtain a second demodulation signal; then, decoding the second demodulation signal to obtain second communication information; thus, simultaneous charging and communication, namely, charging and communication are realized.

Further, after S1403, the method may further include:

generating a second response signal based on the second communication information;

and sending the second response signal to the electronic equipment.

It should be noted that, after the charging device obtains the second communication information, the charging device may further generate a second response signal and send the second response signal to the electronic device, so that the electronic device can know a related state of the charging device, such as a cover-opening state of the charging device, to determine whether the charging device has been opened; or the charging state of the charging equipment so as to determine the charging start or the charging end of the charging equipment and the like; or the electronic equipment enters the box state to determine whether the charging equipment already knows that the electronic equipment enters the box or not, so that the communication between the charging equipment and the electronic equipment can be better realized.

The embodiment provides a communication method applied to charging equipment.
