[0033] If similar descriptions of "first / second" appear in the application documents, the following instructions are added. In the following description, the terms "first\second\third" involved are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged in a specific order or sequence where permitted, so that the present embodiment described here can be implemented in an order other than that illustrated or described here.

For example, object A and / or object B may represent three situations: object A exists alone, object A and object B exist at the same time, and object B exists alone.

[0035] The present application embodiment provides a control method, Figure 1 The control method in the embodiment of the present application is shown in FIG. Figure 1 , applied to a first electronic device, the first electronic device includes but is not limited to an All In One (AIO) electronic device (a highly integrated computer device).

[0036] like Figure 1 As shown, the control method includes the following steps S101 to S103:

[0037] Step S101: in response to obtaining that a first port of a first electronic device is in a connection state, controlling a processing module of the first electronic device to obtain a first target state corresponding to the first electronic device.

[0038] In the embodiment of the present application, the first electronic device is configured with a first port, and the first port integrates input and output functions, that is, it can transmit data and receive data. Exemplarily, the first port includes but is not limited to a high-definition multimedia port (High Definition Multimedia Interface, HDMI), a display port (Display Port, DP) and a Type C port.

[0039] In an embodiment of the present application, when a connecting cable is inserted into the first port of the first electronic device, that is, the first port is in a connected state, a processing module (such as a display control module or a central processing unit (CPU)) of the first electronic device is controlled to obtain a first target state corresponding to the first electronic device.

[0040] The first target state represents whether the first electronic device is in the first state or the second state. The first state is different from the second state. For example, the first state represents that the first electronic device is used as a main control device, and the second state represents that the first electronic device is used as an auxiliary device. Alternatively, the first state represents that the first electronic device is used as an auxiliary device, and the second state represents that the first electronic device is used as a main control device.

[0041] Step S102: When the first target state is in the first state, control the first electronic device to be in the first usage mode.

[0042] Exemplarily, the first state represents that when the first electronic device is used as a main control device, the first use mode is a host mode. Alternatively, the first state represents that when the first electronic device is used as an auxiliary device, the first use mode is a display mode.

[0043] When the first electronic device is in the host mode, it means that the first electronic device is responsible for sending data of the first port. When the first electronic device is in the display mode, it means that the first electronic device is responsible for receiving and displaying data of the first port.

[0044] Step S103: when the first target state is in the second state, control the first electronic device to be in the second usage mode; wherein the first usage mode is different from the second usage mode.

[0045] Exemplarily, the second state represents that when the first electronic device is used as a main control device, the second use mode is a host mode. Alternatively, the second state represents that when the first electronic device is used as an auxiliary device, the second use mode is a display mode.

[0046] The first use mode is different from the second use mode. Exemplarily, when the first use mode is the host mode, the second use mode is the display mode. Or when the first use mode is the display mode, the second use mode is the host mode.

[0047] In an embodiment of the present application, the usage mode of the first electronic device is controlled according to the first target state corresponding to the first electronic device. Correspondingly, the usage mode of the second electronic device can be controlled according to the second target state corresponding to the second electronic device. When the usage mode of the first electronic device is inconsistent with the usage mode of the second electronic device, both the first electronic device and the second electronic device can display normally.

[0048] In some embodiments of the present application, the control method includes the following steps S201 to S202.

[0049] Step S201: in response to obtaining that the first port of the first electronic device is in a connected state, controlling the processing module of the first electronic device to obtain a first target state corresponding to the first electronic device.

[0050] Step S202: Detect a signal from a second port of a second electronic device connected to the first port, and if a first condition is met, obtain a second target state corresponding to the second electronic device at the first port; wherein the first condition indicates that the first electronic device and the second electronic device belong to the same type of device.

[0051] In the embodiment of the present application, the second port and the first port are the same type of ports. Therefore, if the first port is an HDMI port, the second port is an HDMI port; if the first port is a DP port, the second port is a DP port; if the first port is a Type C port, the second port is a Type C port.

[0052] In an embodiment of the present application, when a connecting cable is inserted into the first port of the first electronic device, that is, the first port is in a connected state, a signal acquisition request is sent to the second electronic device through the communication port, and when a signal is received from the second port of the second electronic device through the communication port, if a category signal for identifying the second electronic device detected from the second port satisfies a first condition, it is determined that the first electronic device and the second electronic device belong to the same category of devices, and then a status acquisition request is sent to the second electronic device through the communication port, thereby acquiring the second target state corresponding to the second electronic device through the communication port.

[0053] The second target state represents whether the second electronic device is in the first state or the second state. The first state is different from the second state. For example, the first state represents that the second electronic device is used as a main control device, and the second state represents that the second electronic device is used as an auxiliary device. Alternatively, the first state represents that the second electronic device is used as an auxiliary device, and the second state represents that the second electronic device is used as a main control device.

[0054] Exemplarily, if the first electronic device is an AIO device, the second electronic device is also an AIO device.

[0055] Step S203: When the first target state is in the first state and the second target state is in the second state, control the first electronic device to be in the first usage mode and control the second electronic device to be in the second usage mode.

[0056] In an embodiment of the present application, when the first target state is in the first state and the second target state is in the second state, the first electronic device is controlled to be in the first usage mode, and a control instruction is sent to the second electronic device through the communication port, so that the second electronic device responds to the control instruction and controls itself to be in the second usage mode.

[0057] In the embodiment of the present application, when the first target state is in the first state and the second target state is in the second state, if the first state represents that the first electronic device is used as a main control device and the second state represents that the second electronic device is used as an auxiliary device, the first electronic device is controlled to be in a host mode, and a control instruction is sent to the second electronic device through the communication port, so that the second electronic device responds to the control instruction and controls itself to be in a display mode. Alternatively, if the first state represents that the first electronic device is used as an auxiliary device and the second state represents that the second electronic device is used as a main control device, the first electronic device is controlled to be in a display mode, and a control instruction is sent to the second electronic device through the communication port, so that the second electronic device responds to the control instruction and controls itself to be in a host mode.

[0058] Step S204: When the first target state is in the second state and the second target state is in the first state, control the first electronic device to be in the second usage mode and control the second electronic device to be in the first usage mode.

[0059] In an embodiment of the present application, when the first target state is in the second state and the second target state is in the first state, the first electronic device is controlled to be in the second usage mode, and a control instruction is sent to the second electronic device through the communication port, so that the second electronic device responds to the control instruction and controls itself to be in the first usage mode.

[0060] In the embodiment of the present application, when the first target state is in the second state and the second target state is in the first state, if the second state represents that the first electronic device is used as the main control device and the first state represents that the second electronic device is used as the auxiliary device, the first electronic device is controlled to be in the host mode, and a control instruction is sent to the second electronic device through the communication port, so that the second electronic device responds to the control instruction and controls itself to be in the display mode. Alternatively, if the second state represents that the first electronic device is used as the auxiliary device and the first state represents that the second electronic device is used as the main control device, the first electronic device is controlled to be in the display mode, and a control instruction is sent to the second electronic device through the communication port, so that the second electronic device responds to the control instruction and controls itself to be in the host mode.

[0061] In some embodiments of the present application, the first target state includes a first voltage of a preset module of the first electronic device, and the second target state includes a second voltage of a preset module of the second electronic device.

[0062] In the embodiment of the present application, the voltage of the preset module is used to measure whether the electronic device is turned on. Exemplarily, the preset module includes but is not limited to: a display control module (such as a scalar), a wireless network module (Wireless Fidelity, Wi-Fi) and a solid state drive (Solid State Drive, SSD).

[0063] Based on this, the following step S301 is also included.

[0064] Step S301: When the first voltage is a first preset value and the second voltage is a second preset value, control the first electronic device to be in a first state and control the second electronic device to be in a second state; wherein the first preset value is the voltage value of the preset module when the electronic device is powered on, and the second preset value is the voltage value of the preset module when the electronic device is powered off.

[0065] Exemplarily, when the voltage of the scalar module of the first electronic device is a first preset value, and the voltage of the scalar module of the second electronic device is a second preset value, it means that the first electronic device is turned on and the second electronic device is turned off, thereby controlling the first electronic device to be in a first state and controlling the second electronic device to be in a second state. At this time, the first state represents the first electronic device as a main control device, and the second state represents the second electronic device as an auxiliary device. Among them, the voltage of the scalar module in the working state can be 12V. Accordingly, the first electronic device is controlled to be in a host mode, and the second electronic device is controlled to be in a display mode, that is, the first electronic device transmits information to the second port of the second electronic device through the first port for display.

[0066] Exemplarily, when the voltage of the Wi-Fi module of the first electronic device is a first preset value, and the voltage of the Wi-Fi module of the second electronic device is a second preset value, it means that the first electronic device is turned on and the second electronic device is turned off, thereby controlling the first electronic device to be in a first state and controlling the second electronic device to be in a second state. At this time, the first state represents the first electronic device as a main control device, and the second state represents the second electronic device as an auxiliary device. Among them, the voltage of the Wi-Fi module in the working state can be 3.3V or 5V. Accordingly, the first electronic device is controlled to be in host mode and the second electronic device is controlled to be in display mode, that is, the first electronic device transmits information to the second port of the second electronic device through the first port for display.

[0067] Exemplarily, when the voltage of the SSD module of the first electronic device is the first preset value, and the voltage of the SSD module of the second electronic device is the second preset value, it means that the first electronic device is turned on and the second electronic device is turned off, thereby controlling the first electronic device to be in the first state and the second electronic device to be in the second state. At this time, the first state represents the first electronic device as the main control device, and the second state represents the second electronic device as the auxiliary device. Among them, the voltage of the SSD module in the working state can be 3.3V or 5V or 12V. Accordingly, the first electronic device is controlled to be in the host mode and the second electronic device is controlled to be in the display mode, that is, the first electronic device transmits information to the second port of the second electronic device through the first port for display.

[0068] In some embodiments of the present application, the first target state further includes a first connection signal of an external device of the first electronic device, and the second target state includes a second connection signal of an external device of the second electronic device.

[0069] In the embodiment of the present application, the connection signal is used to indicate whether the electronic device is connected to its external device.

[0070] Based on this, the following steps S401 to S402 are also included.

[0071] Step S401: when the first voltage is a first preset value and the second voltage is a first preset value, controlling the first electronic device to be in a first state and controlling the second electronic device to be in a first state.

[0072] In the embodiment of the present application, when the first voltage of the preset module of the first electronic device is the first preset value, and the second voltage of the preset module of the second electronic device is the second preset value, it means that the first electronic device and the second electronic device are both turned on, then the first electronic device and the second electronic device are both controlled to be in the first state. At this time, the states of the two electronic devices are the same, and it is impossible to distinguish which electronic device is the main device and which electronic device is the auxiliary device. Therefore, it is further determined whether the first electronic device and the second electronic device are connected to their external devices. The external device can be a keyboard, and the user inputs information to the electronic device by operating the keyboard. Therefore, the electronic device connected to the external device is controlled to be the main device, and the electronic device not connected to the external device is controlled to be the auxiliary device.

[0073] Step S402: When the first connection signal indicates that the first electronic device is connected to an external device and the second connection signal indicates that the second electronic device is not connected to the external device, control the first electronic device to be in a first state and control the second electronic device to switch from the first state to a second state.

[0074] In the embodiment of the present application, when the first connection signal of the external device of the first electronic device indicates that the first electronic device is connected to the external device, and the second connection signal of the external device of the second electronic device indicates that the second electronic device is not connected to the external device, it means that the user wants the first electronic device to be the main control device. Therefore, the first electronic device is controlled to be in the first state, and the second electronic device is controlled to switch from the first state to the second state. At this time, the first state represents that the first electronic device is used as the main control device, and the second state represents that the second electronic device is used as the auxiliary device. Correspondingly, the first electronic device is controlled to be in the host mode, and the second electronic device is controlled to be in the display mode, that is, the first electronic device transmits information to the second port of the second electronic device through the first port for display.

[0075] In some embodiments of the present application, the following step S501 is also included.

[0076] Step S501: When the first connection signal indicates that the first electronic device is not connected to an external device and the second connection signal indicates that the second electronic device is connected to an external device, control the first electronic device to switch from a first state to a second state and control the second electronic device to be in the first state.

[0077] In the embodiment of the present application, when the first connection signal of the external device of the first electronic device indicates that the first electronic device is not connected to the external device, and the second connection signal of the external device of the second electronic device indicates that the second electronic device is connected to the external device, it means that the user wants the second electronic device to be the main control device. Therefore, the first electronic device is controlled to switch from the first state to the second state, and the second electronic device is controlled to be in the first state. At this time, the first state represents that the first electronic device is used as an auxiliary device, and the second state represents that the second electronic device is used as a main control device. Correspondingly, the first electronic device is controlled to be in display mode, and the second electronic device is controlled to be in host mode, that is, the second electronic device transmits information to the first port of the first electronic device through the second port for display.

[0078] In some embodiments of the present application, the first target state also includes a first working state of an external device of the first electronic device, and the second target state includes a second working state of an external device of the second electronic device.

[0079] In the embodiment of the present application, the working status of the external device represents whether the external device is working.

[0080] Based on this, the following steps S601 to S602 are also included.

[0081] Step S601: when the first connection signal indicates that the first electronic device is connected to an external device, and the second connection signal indicates that the second electronic device is connected to the external device, the first electronic device is controlled to be in the first state, and the second electronic device is controlled to be in the second state.

[0082] In the embodiment of the present application, when the first connection signal of the external device of the first electronic device indicates that the first electronic device is not connected to the external device, and the second connection signal of the external device of the second electronic device indicates that the second electronic device is connected to the external device, at this time, both electronic devices are connected to the external devices, and it is impossible to distinguish which electronic device is the main device and which electronic device is the auxiliary device. Therefore, it is further determined whether the external devices connected to the first electronic device and the second electronic device are working, and then the electronic device that controls the external device to be in a working state is the main device, and the electronic device that controls the external device to be in a dormant state is the auxiliary device.

[0083] Step S602: When the first working state indicates that the external device of the first electronic device is in working state and the second working state indicates that the external device of the second electronic device is in sleep state, control the first electronic device to be in the first state and control the second electronic device to switch from the first state to the second state.

[0084] In the embodiment of the present application, when the first working state of the external device of the first electronic device indicates that the external device of the first electronic device is in working state, and the second working state of the external device of the second electronic device indicates that the external device of the second electronic device is in sleep state, it means that the user wants the first electronic device to be the main control device. Therefore, the first electronic device is controlled to be in the first state, and the second electronic device is controlled to switch from the first state to the second state. At this time, the first state represents that the first electronic device is used as the main control device, and the second state represents that the second electronic device is used as the auxiliary device. Correspondingly, the first electronic device is controlled to be in the host mode, and the second electronic device is controlled to be in the display mode, that is, the first electronic device transmits information to the second port of the second electronic device through the first port for display.

[0085] In some embodiments of the present application, the following step S701 is also included.

[0086] Step S701: When the first working state indicates that the external device of the first electronic device is in a dormant state and the second working state indicates that the external device of the second electronic device is in a working state, control the first electronic device to switch from the first state to the second state and control the second electronic device to be in the first state.

[0087] In the embodiment of the present application, when the first working state of the external device of the first electronic device indicates that the external device of the first electronic device is in a dormant state, and the second working state of the external device of the second electronic device indicates that the external device of the second electronic device is in a working state, it means that the user wants the second electronic device to be the main control device. Therefore, the first electronic device is controlled to switch from the first state to the second state, and the second electronic device is controlled to be in the first state. At this time, the second state represents that the first electronic device is used as an auxiliary device, and the first state represents that the second electronic device is used as a main control device. Correspondingly, the first electronic device is controlled to be in a display mode, and the second electronic device is controlled to be in a host mode, that is, the second electronic device transmits information to the first port of the first electronic device through the second port for display.

[0088] In some embodiments of the present application, the following steps S801 to S804 are also included.

[0089] Step S801: controlling a processing module of a first electronic device to obtain a first pin signal of an external device.

[0090] The first pin signal is used to indicate the working state of the external device of the first electronic device.

[0091] Step S802: Acquire a second pin signal of an external device corresponding to the second electronic device at the first port.

[0092] The second pin signal is used to indicate the working state of the external device of the second electronic device.

[0093] Step S803: determining a first working state of an external device of the first electronic device based on the first pin signal.

[0094] Exemplarily, if the first pin signal is a high-level signal, the first working state of the external device of the first electronic device indicates that the external device of the first electronic device is in working state; if the first pin signal is a low-level signal, the first working state of the external device of the first electronic device indicates that the external device of the first electronic device is in sleep state. Alternatively, if the first pin signal is a low-level signal, the first working state of the external device of the first electronic device indicates that the external device of the first electronic device is in working state; if the first pin signal is a high-level signal, the first working state of the external device of the first electronic device indicates that the external device of the first electronic device is in sleep state.

[0095] Step S804: determining a second working state of an external device of the second electronic device based on the second pin signal.

[0096] Exemplarily, if the second pin signal is a high-level signal, the second working state of the external device of the second electronic device indicates that the external device of the second electronic device is in working state; if the second pin signal is a low-level signal, the second working state of the external device of the second electronic device indicates that the external device of the second electronic device is in sleep state. Alternatively, if the second pin signal is a low-level signal, the second working state of the external device of the second electronic device indicates that the external device of the second electronic device is in working state; if the second pin signal is a high-level signal, the second working state of the external device of the second electronic device indicates that the external device of the second electronic device is in sleep state.

[0097] In some embodiments of the present application, the further step includes: obtaining a first signal from a first port of the first electronic device; and when the first signal is a low-level signal, indicating that the first port is in a connected state.

[0098] Based on the above embodiments, the present application specifically illustrates a control method: Fig. 9 The control method in the embodiment of the present application is shown in FIG. Figure 9 , applied to a first AIO device (corresponding to a first electronic device), the first AIO device is configured with a first HDMI port (corresponding to a first port).

[0099] like Fig.10 As shown, the first AIO device includes a central processor 1001, a scalar module 1002 and a first HDMI port 1003. Fig. 9The execution subject of the control method shown is the central processing unit 1001.

[0100] like Fig. 9 As shown, the control method includes the following steps S901 to S913.

[0101] Step S901: obtaining a first signal from a first HDMI port of a first AIO device.

[0102] Specifically, based on a communication port such as a display data channel / command interface (DDC / CI), a first signal of a first HDMI port is obtained through a scalar module.

[0103] Step S902: Determine whether the first signal is a low level signal.

[0104] If yes, execute step S903; if no, execute step S901.

[0105] Here, when the first signal is a low-level signal, it indicates that a connection line is inserted into the first HDMI port. When a connection line is inserted into the first HDMI port, the DDC / CI (I2C) path is first converted into a handshake mechanism of a dual-role port (DRP) for judgment and detection. In the DRP mode, the port can dynamically act as a host or a slave, depending on the needs of communication. The following steps S903 to S913 are multiple detection mechanisms.

[0106] Step S903: controlling the scalar module of the first AIO device to obtain the first voltage of the preset module.

[0107] The preset modules include but are not limited to a scalar module, a Wi-Fi module and an SSD module.

[0108] Step S904: Detecting a signal from a second HDMI port of a second AIO device connected to the first HDMI port, and if the first condition is met, obtaining a second voltage of a preset module of the second AIO device.

[0109] The first condition indicates that both connected devices are AIO devices.

[0110] Specifically, based on the communication port such as DDC / CI, the second voltage of the preset module of the second AIO device is obtained through the scalar module.

[0111] Step S905: if the first voltage is a power-on voltage and the second voltage is a power-off voltage, the first AIO device is controlled to be in a host mode and the second AIO device is controlled to be in a display mode.
