[0123] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0124] To solve the above technical problems, embodiments of the present disclosure provide a communication handshake method and apparatus, an electronic device, a power supply device, and a storage medium. When there is a charging requirement, the electronic device accesses the power supply device through a charging bus for charging. Figure 1 It is a schematic diagram of the architecture of the physical connection between an electronic device and a power supply device according to an embodiment of the present disclosure.

[0125] See Figure 1 , the electronic device includes N protocol modules, such as protocol module 1, protocol module 2,..., protocol module N. Among them, N is an integer greater than or equal to 2. The charging protocols adopted by any two of the N protocol modules are different, or in other words, a charging protocol is preset in each protocol module. Moreover, the value ranges of the protocol handshake signals in any two charging protocols are different. For example, the value range of the handshake signal of the first protocol is VL1~VH1, the value range of the handshake signal of the second protocol is VL2~VH2, the value range of the handshake signal of the third protocol is VL3~VH3, and the value range of the handshake signal of the Nth protocol is VLN~VHN. Among them, VL1<VH1<VL2, VL2<VH2<VL3, VL3<VH3<VL4,..., VLN-1<VHN. To increase the recognition of the protocol handshake signal, the signal levels of adjacent value ranges are as large as possible, for example, 0.5V~2V, which can be set according to specific scenarios and is not limited here.

[0126] In this embodiment, the second to Nth protocol modules among the N protocol modules include a transmitting sub-module TX and a receiving sub-module RX.

[0127] The transmitting sub-module TX is used to transmit a first handshake signal to the charging bus.

[0128] The receiving sub-module RX is used to identify the protocol handshake signal of the charging protocol used by the protocol module where the second handshake signal transmitted by the charging bus is located.

[0129] Each of the second to Nth protocol modules is used to establish a communication connection with the power supply device according to its own charging protocol when the second handshake signal of its own charging protocol is recognized.

[0130] It should be noted that the first protocol module among the N protocol modules can be implemented by using a transmitting sub-module TX and a receiving sub-module RX, or can be implemented by using the structure of the second to Nth protocol modules, or can be implemented by using the structure of the master-slave mode. In the case where the first protocol module can establish a physical connection and a communication connection based on the first communication protocol, the corresponding solution falls within the protection scope of the present disclosure.

[0131] In this way, the receiving submodule including at least one signal comparator in this embodiment can identify multiple charging protocols, which is beneficial to improving communication efficiency, and the design is simple and easy to implement.

[0132] Continue to see Figure 1 , the receiving submodule includes at least one signal comparator, which is used to identify the protocol handshake signal of the charging protocol used by the protocol module in the second handshake signal transmitted by the charging bus. In one example, the above-mentioned signal comparator is a window comparator. The window comparator includes: a first reference signal terminal ref1, a second reference signal terminal ref2 and a handshake signal terminal In. Among them, the first reference signal terminal ref1 is used to receive the first reference signal Vref1, the second reference signal terminal ref2 is used to receive the second reference signal Vref2, and the handshake signal terminal In is used to receive the second handshake signal Vin; the signal comparator is used to identify the second handshake signal within the target range; the maximum value of the target range is the second reference signal Vref2 and the minimum value is the first reference signal Vref1.

[0133] In other words, when the protocol handshake signal Vin received by the handshake signal terminal In of the window comparator is between the first reference signal Vref1 and the second reference signal Vref2, the window comparator outputs a first recognition result of successfully identifying the protocol handshake signal; when the protocol handshake signal Vin is less than the first reference signal Vref1 or the protocol handshake signal Vin is greater than the second reference signal Vref2, the window comparator outputs a second recognition result of failing to identify the protocol handshake signal. In an example, the first recognition result may be 1 or a high level, and the second recognition result may be 0 or a low level.

[0134] It should be noted that, considering that there are many window comparators (W1-WN) in the electronic device, the first reference signal terminal of each window comparator is written with a Vref1 signal, corresponding to the VL signal in the above embodiment; and the second reference signal terminal is written with a Vref2 signal, corresponding to the VL signal in the above embodiment. For example, the first reference signal terminal of the first protocol module, i.e., protocol module 1, is written with a Vref1 signal, corresponding to the VL1 signal in the above embodiment; and the second reference signal terminal is written with a Vref2 signal, corresponding to the VL2 signal in the above embodiment, and so on.

[0135] Continue to see Figure 1, each protocol module from the second protocol module to the Nth protocol module further includes a trigger (not shown in the figure), the window comparator includes an enable terminal EN, and the trigger is electrically connected to the enable terminal EN of the window comparator. The trigger is used to output an enable control signal of a preset duration (such as T1, which can be adjusted) after detecting a trigger signal representing that the first protocol module has established a physical connection; the window comparator is used to output a recognition result of identifying the second handshake signal after receiving the enable control signal, and the above recognition result includes a first recognition result of successfully identifying the second handshake signal or a second recognition result of failing to identify the second handshake signal.

[0136] In one embodiment, see Figure 1 , each protocol module from the second protocol module to the Nth protocol module further includes a processor CPU; the processor CPU is electrically connected to at least one signal comparator; the processor CPU is used to determine the second handshake signal according to the preset protocol. In other words, the processor can obtain the recognition result output by the signal comparator, and determine the information expressed by the protocol handshake signal according to the recognition result; and determine the response information according to the protocol handshake signal.

[0137] It should be noted that the number of signal comparators in each protocol module is one, and each of the N protocol modules can respectively identify a protocol handshake signal of a preset protocol; or, the number of signal comparators in each protocol module is multiple, and each of the N protocol modules can identify protocol handshake signals of multiple preset protocols, and can identify protocol handshake signals of up to N preset protocols.

[0138] Taking the number of signal comparators as an example, if there are three signal comparators, the signal value ranges that can be identified by the three signal comparators are adjacent, such as the value range VL1-VH1, the value range VL2-VH2 and the value range VL3-VH3. In this way, this example can identify the protocol handshake signal with a small signal level difference by adding signal comparators, thereby improving the recognition accuracy.

[0139] Continue to see Figure 1, the power supply device includes N protocol modules, such as protocol module 1, protocol module 2, ……, protocol module N. Wherein, N is an integer greater than or equal to 2. Any two of the N protocol modules adopt different charging protocols, or in other words, a charging protocol is preset in each protocol module. Moreover, the value ranges of the protocol handshake signals in any two charging protocols are different. For example, the value range of the handshake signal of the first protocol is VL1~VH1, the value range of the handshake signal of the second protocol is VL2~VH2, the value range of the handshake signal of the third protocol is VL3~VH3, and the value range of the handshake signal of the Nth protocol is VLN~VHN. Wherein, VL1<VH1<VL2, VL2<VH2<VL3, VL3<VH3<VL4, ……, VLN-1<VHN. To increase the recognition of the protocol handshake signal, the signal levels of adjacent value ranges are preferably as large as possible, for example, 0.5V~2V, which can be set according to the specific scenario and is not limited herein.

[0140] In this embodiment, the second to the Nth protocol modules of the N protocol modules of the power supply module include a transmitting sub-module TX and a receiving sub-module RX.

[0141] The transmitting sub-module TX is used to transmit a second handshake signal to the charging bus.

[0142] The receiving sub-module RX is used to identify the protocol handshake signal of the charging protocol used by the protocol module where the first handshake signal transmitted by the charging bus is located.

[0143] Each of the second to the Nth protocol modules is used to establish a communication connection with the power supply device according to its own charging protocol when the first handshake signal of its own charging protocol is recognized.

[0144] In an example, the receiving sub-module RX includes at least one signal comparator, and the signal comparator is used to identify the protocol handshake signal of the charging protocol used by the protocol module where the first handshake signal transmitted by the charging bus is located.

[0145] It should be noted that the first protocol module among the N protocol modules of the power supply device can be implemented by using a transmitting sub-module TX and a receiving sub-module RX, or can be implemented by using the structure of the second to the Nth protocol modules, or can be implemented by using the structure of the master-slave mode. In the case where the first protocol module can establish a physical connection and a communication connection based on the first communication protocol, the corresponding solution falls within the protection scope of the present disclosure.

[0146] In this way, the receiving sub-module including at least one signal comparator provided in this embodiment can identify multiple charging protocols, which is beneficial to improving the communication efficiency, and the design is simple and complex and easy to implement.

[0147] It should be noted that the signal comparator in the power supply device can be a window comparator, which can be referred to the description scheme of the above embodiment. In addition, the numbering principle of the window comparator in the power supply device is the same as the numbering principle of the window comparator in the electronic device, which will not be repeated here.

[0148] Continue to see Figure 1 , each protocol module in the power supply device except the first protocol module also includes a trigger (not shown in the figure), and the trigger is used to output an enable control signal of a preset duration after detecting a trigger signal indicating that the first protocol module has established a physical connection. At this time, the window comparator is used to output a recognition result of identifying the first handshake signal after receiving the enable control signal, and the recognition result includes a third recognition result of successfully identifying the first handshake signal or a fourth recognition result of failing to identify the first handshake signal. In an example, the third recognition result can be 1 or a high level, and the fourth recognition result can be 0 or a low level.

[0149] In one embodiment, see Figure 1 In the power supply device, each protocol module except the first protocol module also includes a processor CPU; the processor CPU is electrically connected to at least one signal comparator; the processor CPU is used to determine the first handshake signal according to the preset protocol. In other words, the processor can obtain the recognition result output by the signal comparator, and determine the information expressed by the protocol handshake signal according to the recognition result; and determine the response information according to the protocol handshake signal.

[0150] based on Figure 1 The electronic device exemplified in the present disclosure also provides a communication handshake method, see Figure 2 , including step 21 and step 22.

[0151] In step 21 , in response to establishing a physical connection with a power supply device, a first handshake signal is output to a charging bus, so that the charging bus transmits the first handshake signal to the power supply device.

[0152] In this step, when the electronic device is plugged into the charging bus, the communication interface of the electronic device can connect the pull-down resistor of the charging bus to the ground, and the power supply device can connect the pull-up resistor of the charging bus to the power supply. At the same time, the electronic device enables the first protocol module and obtains the potential on the charging bus. When it is detected that the potential of the charging bus is pulled down to the second level and no communication connection is established, the electronic device can determine to establish a physical connection with the power supply device.

[0153] In this step, the electronic device can respond to establishing a physical connection with the power supply device and can output a first handshake signal to the charging bus so that the charging bus transmits the first handshake signal to the power supply device. The power supply device can enable the first protocol module of the power supply device and obtain the potential on the charging bus; when it is detected that the potential of the charging bus is pulled up to the first level and no communication connection is established, it is determined to establish a physical connection with the electronic device; when it is detected that the potential of the charging bus is pulled up to the first level and no communication connection is established, the power supply device can determine to establish a physical connection with the electronic device. In response to establishing a physical connection with the electronic device, the power supply device can enable the signal comparator of each protocol module within a preset time length so that the signal comparator identifies the protocol handshake signal of the charging protocol used by the protocol module in the first handshake signal transmitted by the charging bus. Afterwards, the power supply device can respond to identifying the charging protocol corresponding to the first handshake signal and output a second handshake signal according to the charging protocol.

[0154] In step 22, in response to identifying the charging protocol corresponding to the second handshake signal transmitted by the charging bus, a communication connection is established with the charging power supply device according to the charging protocol.

[0155] In this step, the electronic device can determine whether the second handshake signal is received within a preset time length. In response to receiving the second handshake signal, the electronic device can determine the charging protocol corresponding to the second handshake signal. When it is determined that the second handshake signal corresponds to at least one charging protocol, the charging protocol with the highest priority can be determined as the charging protocol corresponding to the second handshake signal according to the preset priority order. In one example, when the second handshake signal is not received, the electronic device can turn off the signal comparator. Then, the electronic device can establish a communication connection with the power supply device based on the first protocol module.

[0156] In this embodiment, in response to the electronic device supporting the charging protocol, the electronic device can establish a communication connection with the power supply device. In another example, when the electronic device does not support the charging protocol, the electronic device can turn off the signal comparator. Then, the electronic device can establish a communication connection with the power supply device based on the first protocol module.

[0157] In this way, the electronic device in this embodiment can use the signal comparator to identify the second handshake signal after sending the first handshake signal, and can identify multiple charging protocols, which is beneficial to improving communication efficiency, and the design is simple and easy to implement.

[0158] based on Figure 1 The power supply device exemplified in the present disclosure also provides a communication handshake method, see Figure 3 , including steps 31 to 33.

[0159] In step 31, in response to establishing a physical connection with an electronic device, a signal comparator of each protocol module is enabled within a preset time period; the signal comparator is used to identify the protocol handshake signal of the charging protocol used by the protocol module in the first handshake signal transmitted by the charging bus.

[0160] In this step, the power supply device can establish a physical connection with the electronic device through the charging bus. The method of establishing the physical connection can refer to the content of step 21 and will not be repeated here.

[0161] In this step, after the physical connection is established, the triggers of each protocol module of the power supply device may be triggered to continuously output an enable control signal for a preset time period, thereby achieving the effect of enabling the signal comparator of each protocol module within the preset time period.

[0162] In step 32, a first handshake signal transmitted by the charging bus is acquired.

[0163] In this step, each signal comparator of each protocol module can receive a protocol handshake signal, ie, a first handshake signal, from the charging bus, and identify a protocol handshake signal of the charging protocol used by the protocol module in the first handshake signal transmitted by the charging bus.

[0164] In step 33, in response to identifying the charging protocol corresponding to the first handshake signal, a second handshake signal is output according to the charging protocol to establish a communication connection with the electronic device.

[0165] In this step, each protocol module of the power supply device determines whether the first handshake signal is received within a preset time. Then, after receiving the first handshake signal, each protocol module can determine the charging protocol corresponding to the first handshake signal. When it is determined that the first handshake signal corresponds to at least one charging protocol, the charging protocol with the highest priority can be determined as the charging protocol corresponding to the first handshake signal according to the preset priority order. Afterwards, when the power supply device supports the charging protocol, the electronic device can output a second handshake signal according to the charging protocol and disconnect the first protocol module to establish a communication connection with the electronic device.

[0166] In one example, in response to not receiving the first handshake signal, the power supply device may turn off the signal comparator and establish a communication connection with the electronic device based on the first protocol module.

[0167] In another example, in response to the power supply device not supporting the charging protocol, the power supply device may turn off the signal comparator and establish a communication connection with the electronic device based on the first protocol module.

[0168] In this way, the power supply device in this embodiment can use the signal comparator to identify the first handshake signal and can identify multiple charging protocols, which is beneficial to improving communication efficiency, and the design is simple and easy to implement.

[0169] Combination Figure 4 ,describe Figure 1 The communication handshake process between the power supply device and the electronic device includes:

[0170] After the communication interface of the electronic device is plugged into the charging bus, the electronic device can enable the first protocol module, and the power supply device can enable the first protocol module. The electronic device can determine whether a physical connection is established with the power supply device but no communication connection is established.

[0171] If the physical connection is not established, the process returns to continue enabling the first protocol module. Alternatively, if the physical connection and the communication connection are established, the first protocol module is directly used for communication.

[0172] If a physical connection is established, the electronic device can determine its own role, that is, a Source device or a Sink device. In this case, the electronic device is a Sink device.

[0173] If a physical connection is established but no communication connection is established, the power supply device, i.e., the Source device, enables the signal comparators of each protocol module. The electronic device sends a first handshake signal through the transmitting submodule according to the preset protocol, and the effect is as follows: Figure 5 As shown, Figure 5 The protocol handshake signals of the first protocol module and the second protocol module are exemplified in FIG.

[0174] During the waiting time, the signal comparators of the protocol modules of the power supply device can receive the first handshake signal sent by the electronic device. It is understandable that, considering that the electronic device includes multiple protocol modules, the first handshake signal can include protocol handshake signals of multiple protocols.

[0175] The power supply device may determine whether the first handshake signal is detected within the waiting time. If the first handshake signal is not detected, the power supply device may turn off the signal comparator and continue to establish a communication connection using the first protocol module.

[0176] If the first handshake signal is detected, the power supply device can determine the charging protocol corresponding to the first handshake signal and determine whether to support the charging protocol. If the power supply device does not support the charging protocol, the power supply device can turn off the signal comparator and continue to use the first protocol module to establish a communication connection.

[0177] If the power supply device supports the charging protocol, the power supply device may disconnect the first protocol module and establish communication using a protocol module corresponding to the charging protocol.

[0178] In this embodiment, the power supply device can use the signal comparator to identify multiple charging protocols, which has high compatibility and is conducive to improving communication efficiency.
