This technology involves two coils, one in the wireless charging device as a transmitter, and the other in the device to be charged as a receiver. When the transmitter coil is powered, a changing magnetic field is generated, which in turn induces an electric signal in the receiver coil, thereby achieving wireless transmission of energy.

[0071] The technical solutions of the present application will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application. In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0072] In a wireless charging scenario, when wireless charging is performed, the to-be-charged device usually needs to determine the charging protocol with the wireless charging device first, and then performs wireless charging through the charging protocol. However, in the prior art, it is usually difficult to accurately and quickly identify the charging protocol.

[0073] For example, the receiving end detects the current working frequency of the received electric signal in real time, and takes the F1 frequency value as the reference frequency. When it is detected that the current working frequency changes from F1 to F2, it is determined that wireless charging is performed through the target charging protocol. However, in this way, only the frequency change from F1 to F2 is used for protocol identification, which can only be applied to a single charging protocol scenario. When there are multiple charging protocols, it is usually difficult to quickly and accurately identify the charging protocol.

[0074] Based on the defects of the related art described above, the embodiments of the present application provide a protocol identification method, device, electronic device, storage medium and program product, which aims to quickly and accurately identify the charging protocol when wireless charging is performed.

[0075] The embodiments of the present application provide a protocol identification method, which can be applied to an electronic device. The type of the electronic device is not limited in the present application, which can be any suitable device type, such as a terminal device and a server, and the like. The present application will not be described here.

[0076] Referring to FIG. 1, a schematic diagram of a protocol identification scenario is shown. The scenario shown in FIG. 1 includes a to-be-charged device and a wireless charging device. The wireless charging device includes an inverter and a transmitter. The to-be-charged device includes a rectifier circuit and a receiver. The wireless charging device can energize the transmitter through the inverter. After the transmitter is energized, a changing magnetic field is generated. The receiver generates an electric signal from the changing magnetic field, and can perform subsequent processing on the electric signal through the rectifier circuit, thereby realizing wireless transmission of energy between the to-be-charged device and the wireless charging device. In this process, the to-be-charged device can identify the current target charging protocol according to the change of the electric signal, and then can perform wireless charging.

[0077] The method for protocol identification in the embodiment of the present application will be described below in combination with FIG. 1 and FIG. 2. Referring to FIG. 2, it is a flow chart of the method for protocol identification in the embodiment of the present application, which is applied to the device to be charged in FIG. 1. The method will be described below in combination with FIG. 2. The specific implementation process of the method is as follows:

[0078] Step 201: When receiving the electric signal sent by the wireless charging device, obtaining a parameter value sequence of a target signal parameter of the electric signal.

[0079] In an embodiment, after the device to be charged contacts the wireless charging device, the wireless charging generates a changing magnetic field through the transmitter. The device to be charged obtains the electric signal excited by the receiver to the changing magnetic field. The device to be charged samples the electric signal in a period of time, can obtain multiple parameter values of the target signal parameter, and obtains a parameter value sequence composed of the parameter values.

[0080] The target signal parameter includes at least one of the following: frequency and voltage. In actual application, the target signal parameter can be set according to the actual application scene. For example, the target signal parameter can also be current. This is not limited here.

[0081] Further, if the parameter values of the target signal parameter meet the waveform curve rule, the parameter value sequence is generated according to the peak value in the parameter values.

[0082] The waveform curve rule can be set according to the periodic change of the parameter value. For example, if the voltage curve is a sine wave, it is determined that the waveform curve rule is met.

[0083] In this way, the voltage sequence or the frequency sequence of the excited electric signal can be obtained.

[0084] Step 202: According to the category number of the target parameter value meeting the set screening condition in the parameter value sequence, the corresponding target charging protocol is determined, or according to the parameter code generated based on the parameter value sequence, the corresponding target charging protocol is determined.

[0085] In an embodiment, when step 202 is performed, any of the following methods can be used:

[0086] Method one: According to the category number of the target parameter value meeting the set screening condition in the parameter value sequence, the corresponding target charging protocol is determined.

[0087] Optionally, the set screening condition can be a specified parameter set. Different target parameter values can correspond to different categories, or the parameter value interval corresponding to each category is set in advance, so that the category to which each target parameter value belongs can be determined, and the number of categories is counted.

[0088] In an implementation, target parameter values contained in the designated parameter set are filtered from the parameter value sequence; the number of categories of the filtered target parameter values is determined; and a charging protocol corresponding to the number of categories is determined as the target charging protocol.

[0089] The number of categories and the charging protocol can be pre-established in a corresponding relationship, so that the target charging protocol corresponding to the number of categories of the electrical signal can be determined according to the corresponding relationship.

[0090] When the charging protocol contains only two, if the number of categories is not less than a set number, the target charging protocol can be determined as the first charging protocol, otherwise, the target charging protocol is determined as the second charging protocol.

[0091] For example, the first charging protocol can be a Power Matters Alliance (PMA) protocol, and the second charging protocol can be a qi protocol.

[0092] For example, if the target signal parameter is frequency, the set number can be not less than 3, and if the target signal parameter is voltage, the set number can be not less than 2. In actual application, the set number can be set according to the actual application scene, which is not limited here.

[0093] To improve the richness of the information transmitted based on the target signal parameter, the number of types of parameter values in the designated parameter set is not less than a set number, and the difference between any two adjacent parameter values in the designated parameter set can be greater than X, X is a positive number.

[0094] The following is an example combined with FIG. 3. Referring to FIG. 3, it is an example diagram of a frequency signal. In FIG. 3, the frequencies are F1, F2 and F3 in turn. Assuming that the set number is 3, and the designated parameter set contains F1, F2 and F3. After the mobile phone (i.e. the device to be charged) is placed on the wireless base (i.e. the wireless charging device), the wireless base provides initial working energy and constantly changes its working frequency to contain F1, F2 and F3. After the mobile phone receives the electrical signal, it determines that the electrical signal contains the frequency sequence (i.e. the parameter value sequence) of F1, F2 and F3. Since the parameter value sequence and the designated parameter set both contain F1, F2 and F3, the number of categories is 3 = the set number.

[0095] The following is an example combined with FIG. 4. Referring to FIG. 4, it is a flowchart of a method for protocol identification based on frequency. The flow of the method includes:

[0096] S401: The wireless charging device regulates the frequency of the electrical signal and sends the regulated electrical signal.

[0097] S402: The to-be-charged device parses the received electric signal to obtain a parameter value sequence containing a plurality of frequency values.

[0098] S403: The to-be-charged device screens out target parameter values contained in the designated parameter set in the parameter value sequence.

[0099] S404: The to-be-charged device determines whether the number of categories of the target parameter values is higher than a set number. If yes, S405 is executed; otherwise, S406 is executed.

[0100] S405: The to-be-charged device determines that the target charging protocol is the first charging protocol.

[0101] S406: The to-be-charged device determines that the target charging protocol is the second charging protocol.

[0102] In this way, the charging protocol can be accurately identified according to the number of types of frequencies of the electric signal, the detection manner is more reliable, the accuracy of protocol identification is improved, and the implementation manner is simpler without considering the sorting of various types of frequencies.

[0103] Method two: determining the corresponding target charging protocol according to a parameter code generated based on the parameter value sequence.

[0104] In an implementation manner, the parameter code corresponding to the parameter value sequence is obtained according to the correspondence between the parameter values and the code values and each parameter value in the parameter value sequence; and the charging protocol corresponding to the parameter code is determined as the target charging protocol.

[0105] The correspondence between the parameter values and the code values can be established in advance to perform coding, and the correspondence between the parameter code and the charging protocol can be established in advance to identify the target charging protocol.

[0106] When the charging protocol is only two, if the parameter code is a target code, the target charging protocol can be determined as the first charging protocol; otherwise, the target charging protocol is determined as the second charging protocol.

[0107] Optionally, the target code can correspond to at least three parameter values. The following multiple cases can be included:

[0108] The first case is that the parameter value sequence is a voltage value sequence. The correspondence between the voltage values and the code values can be established in advance, and then the code values corresponding to each voltage value in the voltage value sequence can be obtained, and the parameter code is determined based on the code values.

[0109] In the case where the target signal parameter is voltage, the parameter value of the target signal parameter is determined by the input voltage of the inverter of the wireless charging device. For example, in FIG. 1, the wireless charging device can adjust the input voltage V-AB of the inverter, thereby changing the voltage value sequence of the to-be-charged device.

[0110] Referring to FIG. 5, it is a curve diagram of a voltage signal. Since the voltage signal in FIG. 5 is a waveform diagram, a corresponding voltage value sequence can be generated based on each voltage peak value V1, V2, V3 and V4 in FIG. 5. The corresponding encoding values of V1, V2, V3 and V4 can be 1, 2, 3 and 4 respectively, and the parameter encoding corresponding to the voltage value sequence can be 1234.

[0111] Similarly, referring to FIG. 6, it is another curve diagram of a voltage signal. A corresponding voltage value sequence can be generated based on each voltage peak value V1, V2, V3 and V4 in FIG. 6. The parameter encoding corresponding to the voltage value sequence can be 1234321.

[0112] In this way, the strength control of the wireless base station sending energy can be realized by adjusting the input voltage of the inverter, and the encoding of information can be formed.

[0113] Further, the inverter can also adjust the input voltage by the switching time, that is, by controlling the phase angle θ of the switch of the inverter to realize phase shift control, so that a special voltage waveform is generated on V-AB. With the change of the phase angle θ, information encoding and control can be realized. The output voltage V-CD at the receiving end will produce different voltage values corresponding to different phase angles θ. For example, V1, V2, V3 and V4.

[0114] Referring to FIG. 7, it is a schematic diagram of voltage input and output. It includes four coordinate graphs, and the horizontal coordinates are all time. The first coordinate graph and the second coordinate graph represent the switching time of each switch of the inverter in FIG. 1. The third coordinate graph represents the input voltage V-AB of the inverter, and the fourth coordinate graph is the output voltage V-CD. When the phase angle θ is fixed, the output voltage V-CD is constant, for example, the output voltage V-CD is V1. When the phase angle θ changes, the input voltage V-AB changes, and the output voltage V-CD also changes accordingly.

[0115] Referring to FIG. 8, it is a flow chart of a method for voltage-based protocol identification. The flow of the method includes:

[0116] S801: The wireless charging device regulates the voltage of the electric signal and sends the regulated electric signal.

[0117] S802: The to-be-charged device analyzes the received electric signal to obtain a parameter value sequence containing multiple voltage values.

[0118] S803: The to-be-charged device generates a parameter encoding based on the parameter value sequence.

[0119] S804: The device to be charged judges whether the parameter code is the target code. If yes, S805 is executed; otherwise, S806 is executed.

[0120] S805: The device to be charged determines that the target charging protocol is the first charging protocol.

[0121] S806: The device to be charged determines that the target charging protocol is the second charging protocol.

[0122] In this way, the voltage value sequence of the receiver can be controlled by adjusting the input voltage of the inverter or adjusting the switching time of the inverter. Since the adjustment range of the voltage value is wide, the voltage value can be flexibly changed and can be any value. Therefore, the coding mode is diversified, various coding modes such as quaternary and octal can be implemented, the coding content is rich, more content information can be carried, the amount of coding content is large, and the wireless receiving end can obtain more information, thereby reducing the information interaction time.

[0123] Further, the target signal parameter can also be a current, and the parameter value sequence is a current value sequence. A corresponding relationship between the current value and the code value can be established in advance, and then the code value corresponding to each current value in the current value sequence can be obtained, and the parameter code is determined based on each code value. The current value can be coded based on a similar principle as the voltage value coding, which will not be described here.

[0124] The second case is that the parameter value sequence is a frequency value sequence. A corresponding relationship between the frequency value and the code value can be established in advance, and then the code value corresponding to each frequency value in the frequency value sequence can be obtained, and the parameter code is determined based on each code value.

[0125] Optionally, the plurality of frequency values of the electric signal can be directly extracted, and each frequency value can also be obtained by analyzing the electric signal based on a reference frequency value. Further, a difference between each frequency value and the reference frequency value of the reference frequency can be determined, and the parameter code can be obtained according to the code value corresponding to each difference. The reference frequency can also be referred to as a reference frequency. For example, the reference frequency value is also stored in the chip of the device to be charged, and the frequency change is detected with the reference frequency value as the reference, so that the parameter code can be quickly implemented.

[0126] Referring to FIG. 9, an example diagram of a reference frequency is shown. In FIG. 9, the reference frequency value can be represented as Fref. Referring to FIG. 10, an example diagram of a frequency of an electric signal is shown. In FIG. 10, the frequency values of the electric signal are F1, F2, Fref, F3, and F4 in sequence.

[0127] Referring to FIG. 11, a flowchart of a method for protocol identification based on frequency coding is shown. The flowchart of the method comprises the following steps:

[0128] S1101: The wireless charging device regulates the frequency of the electrical signal and sends the regulated electrical signal.

[0129] S1102: The device to be charged analyzes the received electrical signal to obtain a sequence of parameter values ​​containing multiple frequency values.

[0130] S1103: Parameter encoding generated by the device to be charged based on the parameter value sequence.

[0131] S1104: The device to be charged determines whether the parameter code is the target code. If yes, proceed to S1105; otherwise, proceed to S1106.

[0132] S1105: The device to be charged determines the target charging protocol as the first charging protocol.

[0133] S1106: The device to be charged determines that the target charging protocol is the second charging protocol.

[0134] In this way, wireless charging devices can change their operating frequency based on the reference frequency Fref to achieve information transmission during energy transfer. Since the frequency value has a wide adjustment range, it can be flexibly changed and can be any value. Therefore, the encoding methods are diversified, and multiple encoding methods such as quaternary and octal can be implemented. The encoded content is rich, carrying more content information. The large amount of encoded content is beneficial for the wireless receiver to obtain more information and can reduce the information interaction time.

[0135] Furthermore, a response message can be sent to the wireless charging device via the target charging protocol to enable wireless charging.

[0136] In one embodiment, when the target charging protocol is a first charging protocol, a response message is sent to the wireless charging device through the first charging protocol; when the target charging protocol is a second charging protocol, a response message is sent to the wireless charging device through the second charging protocol.

[0137] Furthermore, when a new electrical signal is received from a wireless charging device, the corresponding interaction information can be determined based on the number of categories corresponding to the new electrical signal, or based on the parameter encoding corresponding to the new electrical signal.

[0138] In one implementation, upon determining that a new electrical signal has been received from a wireless charging device, a new sequence of parameter values ​​for the target signal parameters is obtained based on the new electrical signal. According to the correspondence between parameter values ​​and encoded values, and the parameter encoding corresponding to the new parameter value sequence, and according to the correspondence between parameter encoding and information, the interaction information corresponding to the new parameter encoding is obtained. Similarly, the interaction information corresponding to the number of categories can also be obtained, which will not be elaborated here.

[0139] Further, the to-be-charged device can also return transmission information to the wireless charging device by using a similar principle to the transmission interaction, which is not described herein.

[0140] In this way, not only can information transmission and analysis be performed based on the electrical signal and parameter coding in the initial stage of identifying the charging protocol, but also information can be transmitted to the receiving end by this method after entering the charging state, so as to realize information interaction with the wireless charging device.

[0141] In the embodiments of the present application, the corresponding target charging protocol is determined based on the number of categories of target signal parameters or parameter coding, which can carry more abundant information, can be applied to protocol identification in a scenario where multiple charging protocols exist, and can improve the efficiency and accuracy of protocol identification.

[0142] The user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for analysis, stored data, displayed data, etc.) involved in the present application are all information and data authorized by the user or authorized by all parties, and the collection, use and processing of related data need to comply with relevant laws, regulations and standards of relevant countries and regions, and provide corresponding operation entrances for users to choose authorization or refusal.

[0143] Based on the same inventive concept, the embodiments of the present application also provide a device for protocol identification. Since the above device and equipment solve the problem by similar principles to the method of protocol identification, the implementation of the above device can be referred to the implementation of the method, and the repeated parts will not be described herein. The device can be applied to electronic devices, and the type of electronic device is not limited in the present application, which can be any suitable device type, such as terminal device and server, etc., which will not be described herein.

[0144] Referring to FIG. 12, it is a structural block diagram of the device for protocol identification in the embodiments of the present application. In some embodiments, the device for protocol identification of the present application includes:

[0145] The obtaining unit 1201 is configured to determine the parameter value sequence of the target signal parameter of the electrical signal when the electrical signal sent by the wireless charging device is received.

[0146] The determining unit 1202 is configured to determine the corresponding target charging protocol according to the number of categories of target parameter values in the parameter value sequence that meet the set screening condition, or determine the corresponding target charging protocol according to the parameter coding generated based on the parameter value sequence.

[0148] In one embodiment, the determining unit 1202 is used to:

[0170] Figure 13 shows a schematic diagram of the structure of an electronic device 1300. Referring to Figure 13, the electronic device 1300 includes a processor 1310 and a memory 1320, and optionally may also include a power supply 1330, a display unit 1340, and an input unit 1350.

[0171] The processor 1310 is the control center of the electronic device 1300. It connects various components through various interfaces and lines, and performs various functions of the electronic device 1300 by running or executing software programs and / or data stored in the memory 1320, thereby performing overall monitoring of the electronic device 1300.

[0172] In this embodiment, when the processor 1310 calls the computer program stored in the memory 1320, it executes the steps in the above embodiments.

[0173] Optionally, processor 1310 may include one or more processing units; preferably, processor 1310 may integrate an application processor and a modem processor, wherein the application processor mainly handles the operating system, user interface, and applications, and the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into processor 1310. In some embodiments, the processor and memory may be implemented on a single chip; in some embodiments, they may also be implemented separately on independent chips.

[0174] The memory 1320 may primarily include a program storage area and a data storage area. The program storage area may store the operating system, various applications, etc.; the data storage area may store data created based on the use of the electronic device 1300, etc. In addition, the memory 1320 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0175] Electronic device 1300 also includes a power supply 1330 (such as a battery) that supplies power to various components. The power supply can be logically connected to processor 1310 through a power management system, thereby enabling the power management system to manage functions such as charging, discharging, and power consumption.

[0176] The display unit 1340 can be used to display information input by the user or information provided to the user, as well as various menus of the electronic device 1300. In this embodiment, it is mainly used to display the display interfaces of various applications in the electronic device 1300, as well as text, images, and other objects displayed on the display interfaces. The display unit 1340 may include a display panel 1341. The display panel 1341 may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like.

[0177] The input unit 1350 can be used to receive information such as numbers or characters input by the user. The input unit 1350 may include a touch panel 1351 and other input devices 1352. The touch panel 1351, also known as a touch screen, can collect touch operations on or near the touch panel 1351 (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near the touch panel 1351).

[0178] Specifically, the touch panel 1351 can detect user touch operations and the signals generated by these operations, convert them into touch point coordinates, send them to the processor 1310, and receive and execute commands from the processor 1310. Furthermore, the touch panel 1351 can be implemented using various types of sensors, including resistive, capacitive, infrared, and surface acoustic wave sensors. Other input devices 1352 can include, but are not limited to, one or more of the following: physical keyboard, function keys (such as volume control buttons, power buttons, etc.), trackball, mouse, joystick, etc.

[0179] Of course, the touch panel 1351 can cover the display panel 1341. When the touch panel 1351 detects a touch operation on or near it, it transmits the information to the processor 1310 to determine the type of touch event. Subsequently, the processor 1310 provides corresponding visual output on the display panel 1341 according to the type of touch event. Although in FIG. 13, the touch panel 1351 and the display panel 1341 are implemented as two separate components to realize the input and output functions of the electronic device 1300, in some embodiments, the touch panel 1351 and the display panel 1341 can be integrated to realize the input and output functions of the electronic device 1300.

[0180] The electronic device 1300 may also include one or more sensors, such as a pressure sensor, a gravity acceleration sensor, a proximity light sensor, etc. Of course, depending on the needs of a specific application, the electronic device 1300 may also include other components such as a camera. Since these components are not the focus of this application embodiment, they are not shown in Figure 13 and will not be described in detail.

[0181] Those skilled in the art will understand that Figure 13 is merely an example of an electronic device and does not constitute a limitation on the electronic device. It may include more or fewer components than shown, or combine certain components, or use different components.

[0182] For ease of description, the above sections are divided into modules (or units) according to their functions and described separately. Of course, in implementing this application, the functions of each module (or unit) can be implemented in one or more software or hardware components.
