[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0049] This application provides a communication method that can be applied to electronic devices. This application does not limit the type of electronic device; see reference [link / reference]. Figure 1 The illustrated communication method scenario diagram shows that, in Embodiment 1 of this application, the method may include, but is not limited to, the following steps:

[0050] Step S101: Determine that the second electronic device is connected to the power line interface of the first electronic device, supply power to the second electronic device through the power line interface, and at the same time, establish a communication connection between the first electronic device and the second electronic device based on the power line interface, and realize data transmission between the first electronic device and the second electronic device through the communication connection established based on the power line interface.

[0051] The power line interface includes a first conductive interface and a second conductive interface. The first conductive interface is connected to the positive terminal of the power line of the first electronic device, and the second conductive interface is connected to the negative terminal of the power line. The second electronic device is an auxiliary device of the first electronic device.

[0052] Corresponding to the first conductive interface and the second conductive interface, the second electronic device includes a third conductive interface and a fourth conductive interface. The positive terminals of the power lines of the second electronic device are connected through the third conductive interface, and the negative terminals of the power lines of the second electronic device are connected through the fourth conductive interface.

[0053] In this application, the interface types of the first and second conductive interfaces are not limited. For example, the first and second conductive interfaces may include, but are not limited to, a first metal contact and a second metal contact of a 2-pin POGO Pin. Corresponding to the implementation where the first and second conductive interfaces are 2-pin POGO Pins with first and second metal contacts, the third and fourth conductive interfaces may include a first spring-loaded pin and a second spring-loaded pin of the 2-pin POGO Pin, and the second electronic device can be connected to the first and second metal contacts of the first electronic device via the first and second spring-loaded pins.

[0054] In this embodiment, the first processor of the first electronic device can be connected to the first conductive interface and the second conductive interface via a power line connection. The first processor determines that the second electronic device is connected to the power line interface of the first electronic device and can send a first enable signal to the power supply module of the first electronic device to enable the power supply module to start supplying power.

[0055] In this embodiment, the power supply module of the first electronic device can be connected to the first conductive interface and the second conductive interface of the first electronic device via a power line connection, and supplies power to the second electronic device through the first conductive interface and the second conductive interface.

[0056] The power supply module of the first electronic device may include, but is not limited to, a power module, a DC / DC converter, and a power filter. The DC / DC converter is connected to the power module, and the power filter is connected to the DC / DC converter, a first conductive interface, and a second conductive interface. The DC / DC converter is used to convert the voltage output by the power module into a voltage that can be used by the second electronic device, and the power filter is used to filter out interference signals in the voltage signal output by the DC / DC converter.

[0057] While supplying power to the second electronic device through the first conductive interface and the second conductive interface, the first processor can establish a communication connection between the first electronic device and the second electronic device based on the first conductive interface and the second conductive interface, and realize data transmission between the first electronic device and the second electronic device through the communication connection established based on the first conductive interface and the second conductive interface.

[0058] The auxiliary devices of the first electronic device can be used to assist in the use of the first electronic device. In this application, there is no limitation on the type of auxiliary devices for the first electronic device.

[0059] It should be noted that, Figure 1 This is merely an example of a communication method and is not intended to limit the specific implementation of the first and second electronic devices.

[0060] In this embodiment, the first electronic device can supply power to the second electronic device, which is an auxiliary device, and the communication connection between the first electronic device and the second electronic device can be realized through the power line interface. This reduces the number of interfaces required for the first electronic device, thereby reducing the number of corresponding fault points and the probability of failure, improving the stability of power supply and communication, and enhancing the user experience of the first and second electronic devices.

[0061] As another optional embodiment of this application, this embodiment is mainly a refinement of the communication method described in Embodiment 1 above. In Embodiment 2 of this application, the step S101 of determining that the second electronic device is connected to the power line interface of the first electronic device may include, but is not limited to:

[0062] Step S1011: Determine that the second electronic device is connected to the power line interface of the first electronic device based on the sensing signal of the power line interface of the first electronic device's sensing device.

[0063] The sensing device of the first electronic device can sense the connection status of the power line interface to generate a sensing signal. The sensing signal can be sent to the first processor of the first electronic device. If the first processor receives the sensing signal, it can determine that the second electronic device is connected to the power line interface of the first electronic device.

[0064] This application does not limit the type of sensing device. For example, the sensing device may include, but is not limited to, a Hall sensor. The sensing area of ​​a Hall sensor includes a power line interface, such as... Figure 2 As shown, a magnetic attraction area exists within the sensing area of ​​the Hall sensor. In an implementation where the sensing device is a Hall sensor, the second electronic device may be equipped with a magnetic component. The magnetic field of the magnetic attraction area corresponding to the magnetic component on the second electronic device differs from the magnetic field of the magnetic attraction area on the first electronic device. If the second electronic device is connected to the power line interface of the first electronic device, the first and second electronic devices can be magnetically connected based on their respective magnetic attraction areas. If the Hall sensor senses a change in the magnetic field of the magnetic attraction area, it can generate an interrupt signal, which is transmitted to the first processor. Accordingly, if the first processor receives the interrupt signal, it can determine that the second electronic device is connected to the power line interface of the first electronic device.

[0065] In this embodiment, the first electronic device determines access by setting a sensing device, which simplifies the circuit design and access determination logic of the first electronic device.

[0066] As another optional embodiment of this application, this embodiment is mainly a refinement of the communication method described in Embodiment 1 above. In Embodiment 3 of this application, the step S101 of establishing a communication connection between the first electronic device and the second electronic device based on the power line interface may include, but is not limited to:

[0067] Step S1012: In response to determining that the second electronic device is connected to the power line interface of the first electronic device, the first communication chip of the first electronic device is switched from an idle state to a wake-up state. The first communication chip is used to modulate the communication data of the established communication connection into a communication signal with a preset carrier frequency for transmission to the second electronic device through the power line interface. The power consumption of the first communication chip in the idle state is lower than that in the wake-up state.

[0068] When the power line interface of the first electronic device is not connected to the second electronic device, the first communication chip of the first electronic device can be in an idle state.

[0069] Specifically, in response to determining that the second electronic device is connected to the power line interface of the first electronic device, the first processor may send a second enable signal to the first communication chip of the first electronic device, so that the first communication chip switches from an idle state to a wake-up state in response to the second enable signal.

[0070] The first communication chip, in a wake-up state, modulates the communication data used to establish the communication connection into a communication signal at a preset carrier frequency for transmission to the second electronic device via a power line interface. The second communication chip in the second electronic device responds to the communication signal from the first electronic device, modulating the response data into a communication signal at the preset carrier frequency and returning it to the first electronic device via its power line interface. The first electronic device, responding to the returned communication signal from the second electronic device, establishes a communication connection between itself and the second electronic device.

[0071] Specifically, the first communication chip can modulate the communication data used to establish the communication connection into a communication signal with a preset carrier frequency and transmit it to the second electronic device through a power line communication analog front-end (PLC AFE), a coupling circuit module (Coupling Unit), a high-pass filter (HPF), and a power line interface. Correspondingly, the second communication chip of the second electronic device can receive the communication signals from the first electronic device through the power line interface, high-pass filter (HPF), coupling circuit module (Coupling Unit), and power line communication analog front-end (PLC AFE) of the second electronic device. Similarly, the second communication chip can transmit communication signals to the first electronic device through the power line communication analog front-end (PLC AFE), coupling circuit module (Coupling Unit), high-pass filter (HPF), and power line interface of the second electronic device; correspondingly, the first communication chip can receive the communication signals from the second electronic device through the power line interface, high-pass filter (HPF), coupling circuit module (Coupling Unit), and power line communication analog front-end (PLC AFE) of the first electronic device.

[0072] The first communication chip may include, but is not limited to, a power line communication baseband processor (PLC Baseband Processor). Correspondingly, the second communication chip may include, but is not limited to, a power line communication baseband processor (PLC Baseband Processor), such as... Figure 3 As shown, if the Hall sensor of the first electronic device senses a change in the magnetic field of the magnetic attraction area, it can generate an interrupt signal and transmit the interrupt signal to the first processor. Correspondingly, if the first processor receives the interrupt signal, it can send a first enable signal (EN1) to the DC power converter and a second enable signal (EN2) to the power line communication baseband processor. In response to the first enable signal, the DC power converter starts to supply power to the second electronic device through the metal contacts of the power line interface. The second electronic device supplies power to the power line communication analog front end (PLC AFE), coupling circuit module (Coupling Unit), and high-pass filter (HPF) of the second electronic device through the power filter and the DC power converter.

[0073] In response to the second enable signal, the power line communication baseband processor switches from an idle state to a wake-up state and modulates the communication data for establishing the communication connection into a communication signal with a preset carrier frequency, which is then transmitted to the second electronic device through the power line communication analog front end (PLCAFE), coupling unit, high-pass filter (HPF), and metal contacts of the power line interface.

[0074] Accordingly, the power line communication baseband processor of the second electronic device can receive communication signals from the first electronic device through the spring pin, high-pass filter (HPF), coupling unit, and power line communication analog front end (PLC AFE) of the power line interface of the second electronic device. Figure 3 The process of the second electronic device transmitting communication signals to the first electronic device can be found in the process of the first electronic device transmitting communication signals to the second electronic device, and will not be repeated here.

[0075] Figure 3 In the PLC, RGMII stands for Simplified Gigabit Media Independent Interface, SPI stands for Serial Peripheral Interface, PLC_Tx stands for Power Communication Transmitter, and PLC_Rx stands for Power Communication Receiver.

[0076] It should be noted that, Figure 3 This is merely a circuit diagram of the first and second electronic devices and is not intended to limit the circuitry of the first and second electronic devices.

[0077] In this embodiment, the detailed process of determining the connection of the second electronic device to the power line interface of the first electronic device can be found in the relevant description in Embodiment 2, and will not be repeated here.

[0078] In this embodiment, in response to determining that the second electronic device is connected to the power line interface of the first electronic device, the first communication chip of the first electronic device is switched from an idle state to a wake-up state. This allows the first communication chip to be in an idle state before the second electronic device is connected to the power line interface of the first electronic device, thus saving power consumption of the first electronic device.

[0079] As another optional embodiment of this application, this embodiment is mainly a refinement of the communication method described in Embodiment 1 above. In Embodiment 4 of this application, the data transmission between the first electronic device and the second electronic device is realized through a communication connection established based on the power line interface in step S101, which may include, but is not limited to:

[0080] Step S1013: Obtain the identity information of the second electronic device through a communication connection established based on the power line interface.

[0081] Through a communication connection established based on a power line interface, the first electronic device can send a broadcast signal to the second electronic device, and in response to the broadcast signal, the second electronic device can send its identity information to the first electronic device based on the communication connection.

[0082] The identity information of the second electronic device can identify the identity of the second electronic device.

[0083] Step S1014: Data transmission between the first electronic device and the second electronic device is realized based on the identity information and communication connection of the second electronic device.

[0084] In this embodiment, the identity of the second electronic device can be determined based on its identity information, and the data content that can be transmitted between the first and second electronic devices can be determined based on its identity.

[0085] Based on the communication connection, data content that can be transmitted between the first electronic device and the second electronic device can be transmitted.

[0086] In this embodiment, data from the first electronic device can act on the second electronic device, and data sent from the second electronic device to the first electronic device originates from the second electronic device. The second electronic device may include, but is not limited to, a keyboard, a second processor, a second power line interface, and a second communication chip. The second power line interface may include a third conductive interface and a fourth conductive interface. The identity information of the second electronic device may include, but is not limited to, the network identifier and communication address of the second electronic device. For example, such as... Figure 4As shown, the first electronic device and the second electronic device can be connected via a first power line interface and a second power line interface.

[0087] The keyboard is used to input key information. A second communication chip is connected to a second processor. The second processor controls the transmission of the input key information to the second communication chip. The second communication chip modulates the key information into a communication signal with a preset carrier frequency and transmits it to the first electronic device via a second power line interface. The second power line interface is connected to the first power line interface of the first electronic device. The second communication chip can also receive communication signals from the first electronic device via the second power line interface, demodulate the communication signals from the first electronic device, and transmit them to the second processor. The communication signals from the first electronic device are communication signals modulated by the first communication chip from the data of the first electronic device into a communication signal with a preset carrier frequency.

[0088] For example, if the second power line interface is a 2-pin POGO Pin with a first and second spring-loaded pin, and the second communication chip is a power line communication baseband processor, such as... Figure 5 As shown, the power line communication baseband processor can demodulate the communication signal from the first electronic device and transmit it to the second processor; the second processor can control the key input from the keyboard to be transmitted to the power line communication baseband processor, and the power line communication baseband processor modulates the key input into a communication signal with a preset carrier frequency and transmits it to the first electronic device through the first spring pin and the second spring pin.

[0089] It should be noted that, Figure 4 and Figure 5 This is a simplified diagram and is not intended to limit the structure of the first and second electronic devices.

[0090] In this embodiment, the identity information of the second electronic device is obtained through a communication connection established based on the power line interface. Data transmission between the first and second electronic devices is realized based on the identity information of the second electronic device and the communication connection, so that the data of the first electronic device can be applied to the second electronic device, and / or the first electronic device can obtain data from the second electronic device.

[0091] Furthermore, by modulating the data into a communication signal with a preset carrier frequency and transmitting the communication signal to transmit the data, the security of data transmission between the first electronic device and the second electronic device can be improved.

[0092] As another optional embodiment of this application, this embodiment is mainly a refinement of the communication method described in Embodiment 1 above. In Embodiment 5 of this application, the data transmission between the first electronic device and the second electronic device is realized through a communication connection established based on the power line interface in step S101, which may include but is not limited to:

[0093] Step S1015: Obtain the identity information of the third electronic device connected to the second electronic device through the communication connection established based on the power line interface.

[0094] Through a communication connection established based on the power line interface, the first electronic device can send a broadcast signal to the second electronic device. In response to the broadcast signal, the second electronic device determines that a third electronic device has accessed the second electronic device and sends the identity information of the third electronic device to the first electronic device based on the communication connection.

[0095] The identity information of a third electronic device can characterize the identity of the third electronic device.

[0096] The second electronic device can be used to establish a connection between the first electronic device and the third electronic device. The second electronic device can transmit data from the first electronic device to the third electronic device, and vice versa.

[0097] Step S1016: Data transmission between the first electronic device and the second electronic device is realized based on the identity information and communication connection of the third electronic device.

[0098] The identity of the third electronic device can be determined based on its identity information, and the data content that can be transmitted between the first electronic device and the third electronic device can be determined based on its identity.

[0099] The first electronic device can transmit data content that can be transmitted between the first electronic device and the third electronic device to the second electronic device based on a communication connection, and the second electronic device can transmit data content from the first electronic device to the third electronic device.

[0100] The third electronic device can also transmit data content that can be transmitted between the first electronic device and the third electronic device to the second electronic device, and the second electronic device can transmit data content from the third electronic device to the first electronic device.

[0101] In this embodiment, the second electronic device may include, but is not limited to, a second power line interface, a connection interface, and a second communication chip.

[0102] The second power line interface can be connected to the first power line interface of the first electronic device. Corresponding to the first power line interface, which includes a first metal contact and a second metal contact of a 2-pin POGO Pin, the second power line interface may include a first spring-loaded pin and a second spring-loaded pin of the 2-pin POGO Pin.

[0103] The connection interface allows connection to a second communication chip and a third electronic device. The connection interface conforms to the first communication protocol, while the power line interface conforms to the second communication protocol; the first and second communication protocols are different. For example... Figure 6 As shown, the second communication chip (e.g., a power line communication baseband processor) can obtain data from the third electronic device through a connection interface. The second communication chip can modulate the data from the third electronic device into a communication signal with a preset carrier frequency, and transmit the communication signal to the first electronic device through the power line communication analog front-end (PLC AFE), coupling circuit module (HPF), high-pass filter (HPF), and power line interface of the second electronic device. Correspondingly, the first communication chip (e.g., a power line communication baseband processor) can receive the communication signals from the second electronic device through the power line interface, high-pass filter (HPF), coupling circuit module (HPF), and power line communication analog front-end (PLC AFE) of the first electronic device.

[0104] The first communication chip can modulate the data of the first electronic device into a communication signal with a preset carrier frequency and transmit it to the second electronic device through the power line communication analog front end (PLC AFE), coupling circuit module (Coupling Unit), high-pass filter (HPF), and power line interface. The second communication chip of the second electronic device can receive the communication signal of the first electronic device through the power line interface, high-pass filter (HPF), coupling circuit module (Coupling Unit), and power line communication analog front end (PLC AFE) of the second electronic device, and transmit the data of the first electronic device to the connection interface, which then transmits the data of the first electronic device to the third electronic device.

[0105] In this embodiment, as Figure 7 As shown, the connection interface may include, but is not limited to, a USB bridge and a USB interface. The USB bridge is used to connect the second communication chip and the USB interface. Corresponding to the USB interface, such as... Figure 8 As shown, the third electronic device can be a USB flash drive, or, as... Figure 9 As shown, the third electronic device can be a mouse or keyboard, etc., connected via a USB interface data cable.

[0106] The second communication chip can modulate data from the third electronic device into a communication signal with a preset carrier frequency and transmit it to the first electronic device, and demodulate the communication signal from the first electronic device and transmit it to the third electronic device connected to the connection interface. The communication signal from the first electronic device is the communication signal modulated by the first communication chip onto the data from the first electronic device at the preset carrier frequency.

[0107] The second communication chip demodulates the communication signal from the first electronic device and transmits it to the third electronic device connected to the connection interface. This may include: the second communication chip demodulates the communication signal from the first electronic device to obtain data, determines that the data is a second communication protocol, converts the data into a first communication protocol, and transmits the data of the first communication protocol to the third electronic device connected to the connection interface.

[0108] Of course, the connection interface can also be used to convert between the first and second communication protocols. Accordingly, the second communication chip can transmit the data obtained by demodulating the communication signal from the first electronic device to the connection interface, which then converts the data from the second communication protocol to the first communication protocol and transmits the data of the first communication protocol to the third electronic device.

[0109] The second electronic device may also be equipped with magnetic components, which can be configured as needed and are not limited in this application. For example, such as Figure 10 The side view of the second electronic device shown in part (a) and Figure 10 The rear front view of the second electronic device shown in part (b) shows that the metal spring pin and the USB interface are disposed on different surfaces of the first electronic device. The second electronic device may include two magnetic components that may be disposed on both sides of the metal spring pin and the USB interface.

[0110] While the metal spring pin of the second electronic device is connected to the metal contact of the first electronic device, based on the magnetic attraction area in the first electronic device and Figure 10 In the second electronic device shown in section (c), the surface of the metal spring pin corresponds to the magnetic attraction area of ​​the magnetic component, such as... Figure 11 As shown, the first electronic device and the second electronic device can be magnetically connected.
