Detailed Description

In order to realize that the electronic equipment can provide services with different interface types at the same time and improve the performance of the electronic equipment, the application provides the electronic equipment, a control method, a device and a medium.

In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In an actual application process, when a user wants to interact with other electronic devices of different interface types through the electronic device at the same time, the other electronic device of a certain interface type (for convenience of description, denoted as a first electronic device) may be connected with a USB interface of a corresponding interface type (for convenience of description, denoted as a first USB interface) on the electronic device, and the other electronic device of another interface type (for convenience of description, denoted as a second electronic device) may be connected with a USB interface of a corresponding interface type (for convenience of description, denoted as a second USB interface) on the electronic device. If the CPU in the electronic equipment determines that the first USB interface is connected with the first other electronic equipment and the second USB interface is connected with the second other electronic equipment, the CPU is electrically connected with the multiplexer through the first line so as to control the multiplexer to send the signal sent by the CPU to the first USB interface and/or the second USB interface, and therefore the electronic equipment can interact with the first other electronic equipment and the second electronic equipment at the same time.

Example 1:

fig. 1 is a schematic structural diagram of an electronic device according to some embodiments of the present application, where the electronic device includes a first USB interface 11, a second USB interface 12, a multiplexer 13, and a central processing unit CPU 14; the first USB interface and the second USB interface are different in interface type;

The electronic equipment provided by the application can be intelligent equipment such as a mobile phone, a computer and the like, and can also be a server and the like.

In an actual application process, when a user wants to interact with other electronic devices of different interface types through the electronic device at the same time, the other electronic device of a certain interface type (for convenience of description, denoted as a first electronic device) may be connected with a USB interface of a corresponding interface type (for convenience of description, denoted as a first USB interface) on the electronic device, and the other electronic device of another interface type (for convenience of description, denoted as a second electronic device) may be connected with a USB interface of a corresponding interface type (for convenience of description, denoted as a second USB interface) on the electronic device.

Wherein, the interface Type comprises a Type-C interface Type and a Type-A interface Type.

It should be noted that, for a USB interface with a Type of Type-a interface, the USB interface can only be connected to other electronic devices (for convenience of description, referred to as otg devices) with a data connection (otg) Type, such as a USB disk, a mouse, a keyboard, and the like; for the USB interface with the Type of Type-C interface, the USB interface may be connected to other electronic devices with otg Type, or may be connected to other electronic devices with display interface (dp) Type (for convenience of description, denoted as dp devices), such as a display, a projector, and the like.

In order that the electronic equipment can provide services with different interface types at the same time, the performance of the electronic equipment is improved, and the electronic equipment comprises a first USB interface, a second USB interface, a multiplexer and a CPU. The first USB interface and the second USB interface are different in interface type and are used for being connected with other electronic equipment. The CPU of the electronic equipment can determine whether other electronic equipment is connected with the current first USB interface and the current second USB interface, and when the CPU of the electronic equipment determines that other electronic equipment is connected with the current first USB interface and the current second USB interface, the CPU of the electronic equipment is electrically connected with a multiplexer of the electronic equipment, and the multiplexer is controlled to send signals sent by the CPU to the first USB interface and/or the second USB interface, so that the electronic equipment can provide services with different interface types at the same time.

In a possible implementation manner, since the first other electronic device is connected to the first USB interface of the electronic device, the state of the CC pin (for convenience of description, referred to as the first CC pin) included in the first USB interface is changed. Therefore, the CPU of the electronic device may determine whether the first USB interface of the electronic device is connected with the first other electronic device by detecting the state of the first CC pin. When the state of the first CC pin is determined to be the state that the first USB interface of the electronic equipment is connected with the first other electronic equipment, determining that the first USB interface of the electronic equipment is connected with the first other electronic equipment; and when the state of the first CC pin is determined not to be the state that the first USB interface of the electronic equipment is connected with the first other electronic equipment, determining that the first USB interface of the electronic equipment is not connected with the first other electronic equipment.

And the CPU can also determine the type of the first other electronic equipment connected with the current first USB interface according to the state of the first CC pin.

Similarly, since a second other electronic device is connected to the second USB interface of the electronic device, the state of the CC pin (for convenience of description, referred to as the second CC pin) included in the second USB interface is changed. Therefore, the CPU of the electronic device may determine whether a second other electronic device is connected to the second USB interface of the electronic device by detecting the state of the second CC pin. When the state of the second CC pin is determined to be the state that the second USB interface of the electronic equipment is connected with second other electronic equipment, determining that the second USB interface of the electronic equipment is connected with the second other electronic equipment; and when the state of the second CC pin is determined not to be the state that the second USB interface of the electronic equipment is connected with the second other electronic equipment, determining that the second USB interface of the electronic equipment is not connected with the second other electronic equipment.

And the CPU can also determine the type of the second other electronic equipment connected with the current second USB interface according to the state of the second CC pin.

In one possible implementation, since the USB2.0 port physical layer (phy) of the USB interface of Type-a (for convenience of description, referred to as Type-a interface) can only be connected to the CPU through the multiplexer (hub), the USB2.0 phy of the USB interface of Type-C (for convenience of description, referred to as Type-C interface) can also be connected to the CPU through the hub. Fig. 2 is a schematic structural diagram of a Type-a interface and a Type-C interface provided in some embodiments of the present application, respectively connected to a CPU. As shown in FIG. 2, the USB2.0 phy of the Type-A interface can be connected with the USB phy of the CPU only through the hub, and the USB2.0 phy of the Type-C interface can also be connected with the USB phy of the CPU through the hub. Therefore, in order to realize that an electronic device can provide services of different interface types at the same time, in the present application, a multiplexer is provided in the electronic device, and the multiplexer can be connected to the CPU through a line (for convenience of description, referred to as a first line). In a specific implementation process, when a CPU in the electronic device determines that the first USB interface is connected with first other electronic devices and the second USB interface is connected with second other electronic devices, the CPU is electrically connected with the multiplexer through the first line, and the subsequent CPU can send signals to the multiplexer through the first line. After receiving the signal sent by the CPU, the multiplexer may send the signal to the corresponding USB interface, that is, to the first USB interface and/or the second USB interface.

The signal may be a data signal, a request signal, or the like.

In one possible embodiment, in order to accurately control the CPU and the multiplexer to be electrically connected, in this application, a switch (for convenience of description, referred to as a first switch) supporting the USB2.0 protocol is provided on the first line. When the CPU of the electronic equipment determines that the first USB interface is connected with first other electronic equipment and the second USB interface is connected with second other electronic equipment, in order to realize the electric connection of the CPU and the multiplexer, the CPU controls the first circuit to be provided with a first switch which supports the USB2.0 protocol to be closed.

In a possible implementation manner, when the electronic device determines that its own USB interface (including the first USB interface and the second USB interface) is connected with the otg device, the first otg loading process is triggered, so that the otg device can normally operate after being connected with the electronic device.

In a possible implementation manner, when the electronic device determines that the USB interface of the electronic device is connected to a dp device, the second otg loading process is triggered to implement transmission of a Power Delivery (PD) protocol, and dp event triggering is completed, so that data sent by the electronic device can be acquired after the dp device is connected to the electronic device.

In one possible implementation, the user may disconnect the first USB interface of the electronic device from the first other electronic device and disconnect the second USB interface of the electronic device from the second other electronic device without requiring the electronic device to simultaneously provide services of different interface types. And the CPU of the electronic device determines that the first USB interface is no longer connected to the first other electronic device and the second USB interface is no longer connected to the second other electronic device, which indicates that the electronic device is no longer required to interact with the first other electronic device and the second other electronic device at the same time, and the CPU may stop being electrically connected to the multiplexer through the first line.

In a possible embodiment, in order to accurately control the CPU not to be electrically connected to the multiplexer, in this application, when the CPU of the electronic device determines that the first USB interface is no longer connected to the first other electronic device and the second USB interface is no longer connected to the second other electronic device, the CPU may control the first switch on the first line to be turned off, that is, control the on-off state of the first switch to be switched from on to off.

In the practical application process, the state of the first CC pin included in the first USB interface is changed due to the disconnection between the first other electronic device and the first USB interface on the electronic device. Therefore, the CPU of the electronic device may determine whether the first USB interface of the electronic device is connected with the first other electronic device by detecting the state of the first CC pin. And when the state of the first CC pin is determined to be the state that the first USB interface of the electronic equipment is not connected with the first other electronic equipment, determining that the first USB interface of the electronic equipment is not connected with the first other electronic equipment.

Similarly, the state of the second CC pin included in the second USB interface is changed due to the disconnection of the second other electronic device from the second USB interface on the electronic device. Therefore, the CPU of the electronic device may determine whether a second other electronic device is connected to the second USB interface of the electronic device by detecting the state of the second CC pin. And when the state of the second CC pin is determined to be the state that the second USB interface of the electronic equipment is not connected with second other electronic equipment, determining that the second USB interface of the electronic equipment is not connected with the second other electronic equipment.

Example 2:

in order to further improve the performance of the electronic device, in the present application, on the basis of the above embodiment, if it is determined that the first USB interface is not connected to the first other electronic device, and it is determined that the second USB interface is not connected to the second other electronic device, the CPU is further configured to control the first switch supporting the USB2.0 protocol on the first line to be opened, and keep the second switch supporting the USB3.0 protocol on the second line to be closed; the second line is used for connecting the CPU and the second USB interface.

In the practical application process, both the USB2.0 phy and the USB3.0 of the Type-C interface can directly interact with the CPU, the USB2.0 phy of the Type-C interface can also be connected with the CPU through hub, and the interaction rate of the electronic equipment and other electronic equipment can be effectively improved through the USB3.0 phy. As shown in FIG. 2, the Type-C interface can also interact directly with the CPU's USB phy. Therefore, in the present application, a line (for convenience of description, referred to as a second line) for directly connecting the CPU and the second USB interface is provided in advance in the electronic device, and a switch (for convenience of description, referred to as a second switch) supporting the USB3.0 protocol is provided in the second line so that the second USB interface can directly interact with the CPU based on the USB3.0 protocol.

In order to avoid that the second USB interface directly interacts with the CPU and affects the interaction between the CPU and the first USB interface and the interaction between the CPU and the second USB interface simultaneously, when the CPU determines that the first USB interface is not connected with first other electronic equipment and determines that the second USB interface is not connected with second other electronic equipment, the electronic equipment does not need to interact with the first other electronic equipment and the second other electronic equipment simultaneously, the CPU can be controlled to be disconnected with a first switch supporting the USB2.0 protocol on a first line, namely, the CPU is electrically connected with the multiplexer, and a second switch supporting the USB3.0 protocol on a second line is kept closed, so that the CPU can be directly electrically connected with the second USB interface, the CPU is convenient to determine that the second USB is connected with the second other electronic equipment, and when the first USB interface is not connected with the first other electronic equipment, the second USB interface can be rapidly realized to directly interact with the CPU based on the USB3.0 protocol, the efficiency of the electronic equipment and the second other electronic equipment interacting is improved.

The second line is used for connecting a CPU on the electronic equipment and a second USB interface on the electronic equipment.

Further, when the CPU determines that the first USB interface is connected to the first other electronic device and the second USB interface is connected to the second other electronic device, the CPU may control the first switch supporting the USB2.0 protocol on the first line to be turned on, that is, the CPU and the multiplexer are electrically connected, and control the second switch supporting the USB3.0 protocol on the second line to be turned off, so as to prevent the second line from affecting the CPU to interact with the second USB interface through the multiplexer.

As a possible implementation manner, if the first USB interface is a Type-a interface, since the physical layer of the USB2.0 port of the Type-a interface can only be connected to the CPU through the multiplexer, and there may be a situation that the user only wants the electronic device to provide services for the first other electronic device, or the user connects the first USB interface to the first other electronic device before connecting the second USB interface to the second other electronic device, or the user disconnects the second USB interface from the second other electronic device after connecting the electronic device to the second other electronic device and the first other electronic device at the same time, so that the CPU on the electronic device currently determines that the first USB interface is connected to the first other electronic device and determines that the second USB interface is not connected to the second other electronic device, which indicates that the CPU needs to interact with the USB interface through the multiplexer, the first switch supporting the USB2.0 protocol on the first line may be controlled to close, i.e. to electrically connect the CPU and the multiplexer. And the second USB interface is not connected with second other electronic equipment, and the CPU does not need to interact with the second other electronic equipment connected with the second USB interface at present, so that the CPU is directly connected with the second USB interface through a second line, and the interaction of the CPU and the first USB interface through the multiplexer is not influenced, therefore, a second switch supporting the USB3.0 protocol on the second line can be kept closed.

As another possible implementation manner, in an actual application process, there may be a case where a user only wants the electronic device to provide a service for a second other electronic device, or the user connects the second USB interface with the second other electronic device before connecting the first USB interface with the first other electronic device, or the user disconnects the first USB interface from the first other electronic device after connecting the electronic device with the first other electronic device and the second other electronic device at the same time, so that when the second USB interface is a Type-a interface, the CPU on the electronic device determines that the first USB interface is not connected with the first other electronic device, and determines that the second USB interface is connected with the second other electronic device. In order to ensure the interaction rate of the CPU and the second USB interface, when the CPU on the electronic device determines that the first USB interface is not connected to the first other electronic device and determines that the second USB interface is connected to the second other electronic device, it indicates that the current CPU does not need to interact with the USB interface through the multiplexer, and may control the first switch supporting the USB2.0 protocol on the first line to be turned off, that is, the electrical connection between the CPU and the multiplexer is turned off, and keep the second switch supporting the USB3.0 protocol on the second line to be turned on, so that the CPU may be directly electrically connected to the second USB interface, thereby conveniently implementing that the second USB interface may directly interact with the CPU based on the USB3.0 protocol, and improving the interaction efficiency of the electronic device and the second other electronic device.

By the method, the CPU can accurately adjust the on-off of the first line and the second line in the electronic equipment according to the condition whether the first USB interface is connected with the first other electronic equipment and the condition whether the second USB interface is connected with the second other electronic equipment, so that the interaction between the electronic equipment and the first other electronic equipment and the interaction between the electronic equipment and the second other electronic equipment are accurately realized, and the interaction quality between the electronic equipment and at least one piece of electronic equipment is ensured.

Example 3:

in order to ensure the quality of the interaction between the CPU and the second USB interface through the multiplexer, in the present application, on the basis of the foregoing embodiments, if it is determined that the first USB interface is connected to the first other electronic device and the second USB interface is connected to the second other electronic device, the CPU is further configured to control a third switch supporting the USB2.0 protocol to be closed on a third line; the third line is used for connecting the line converter and the second USB interface.

In order to ensure the quality of the interaction between the CPU and the second USB interface through the multiplexer, in this application, a third line is further provided in the electronic device, and a third switch supporting the USB2.0 protocol is provided on the third line, and the third line is used for connecting the multiplexer and the second USB interface. When a CPU on the electronic equipment determines that the first USB interface is connected with first other electronic equipment and the second USB interface is connected with second other electronic equipment, in order to ensure that the CPU interacts with the second USB interface through the multiplexer, the CPU controls a third switch supporting a USB2.0 protocol on a third line to be closed so as to realize the electric connection of the multiplexer and the second USB interface, so that the multiplexer can conveniently send a signal sent by the CPU to the second USB interface, and the interaction quality of the CPU and the second USB interface through the multiplexer is ensured.

In a possible implementation manner, in order to ensure that the interaction between the CPU and the USB interface is accurately controlled, in this application, when the CPU on the electronic device does not need to interact with the second USB through the multiplexer, the third switch supporting the USB2.0 protocol on the third line may be controlled to be turned off, so that the influence on the interaction between the CPU and the second USB, which is caused by the presence of multiple lines on the electronic device, and the interaction between the CPU and any USB interface is avoided. Specifically, if it is determined that the first USB interface is not connected to the first other electronic device, and/or the second USB interface is not connected to the second other electronic device, the third switch supporting the USB2.0 protocol on the third line is controlled to be turned off.

In one possible implementation mode, connection conditions of other electronic devices possibly connected by the electronic device and types of the other electronic devices are obtained, and the working mode of the electronic device is determined according to the on-off conditions of the lines (including the first line, the second line and the third line) of the electronic device in each connection condition. If the first USB interface is a Type-a interface and the second USB interface is a Type-C interface, several working modes of the embodiment of the present application are introduced as follows with reference to a schematic circuit connection structure diagram of an electronic device shown in fig. 3:

the default mode and the connection condition corresponding to the working mode are as follows: the first USB interface of the electronic device is not connected with first other electronic devices, and the second USB interface of the electronic device is not connected with second other electronic devices. It is understood that this connection situation is a situation where the electronic device does not interact with any other electronic device, for example, where the electronic device is charged using a Type-C interface. Under the connection condition, the on-off condition of each line of the electronic equipment is that the first switch on the first line is disconnected, the second switch on the second line is closed, the third switch on the third line is disconnected, that is, the first line and the third line are not electrified, and the second line is electrified, so that the CPU of the electronic equipment can still interact with the second USB interface in the default mode, and the functions of charging, file transmission and the like of the electronic equipment can still be realized through the second USB interface.

For example, if a user does not connect a first USB interface of an electronic device with a first other electronic device, the state of the first CC pin in the first USB interface is not changed, and the state of the first pin should be a state where the first other electronic device is not connected. Similarly, if the user does not connect the second other electronic device to the second USB interface of the electronic device, the state of the second CC pin in the second USB interface is not changed, and the state of the second pin is the state of the second other electronic device. Therefore, the CPU of the electronic device determines that the first USB interface is not connected to the first other electronic device and the second USB interface is not connected to the second other electronic device by detecting the state of the first CC pin in the first USB interface and the state of the second CC pin in the second USB interface, and then controls the first switch on the first line to be turned off, the second switch on the second line to be turned on, and the third switch on the third line to be turned off, that is, controls the electronic device to operate in the default mode, and only the second USB interface can be normally used in the default mode. Fig. 4 is a schematic circuit structure diagram of another electronic device according to some embodiments of the present application. As shown in fig. 4, when the first USB interface of the CPU of the electronic device is not connected to the first other electronic device, and the second USB interface is not connected to the second other electronic device, the CPU controls USB3.0SWITCH × 2 to be on, USB2.0 SWITCH1 to be off, and USB2.0 SWITCH2 to be off, so that in the default mode, the CPU can charge the electronic device through the second USB interface, or transmit a file to a computer, a notebook, or the like.

The working mode 1 and the connection condition corresponding to the working mode are as follows: the first USB interface of the electronic device is not connected with the first other electronic device, and the second USB interface of the electronic device is connected with the second other electronic device, wherein the type of the second other electronic device can be dp device or otg device. It will be appreciated that this mode of connection is where the electronic device interacts only with a second other electronic device. In this connection situation, the on-off condition of each line of the electronic device is that the first switch on the first line is open, the second switch on the second line is closed, and the third switch on the third line is open, that is, the first line and the third line are not powered, and the second line is powered on, so that in the working mode 1, the second other electronic device connected with the second USB interface can directly interact with the CPU based on the USB3.0 protocol.

For example, if the second other electronic device is an otg device, after the user connects the second other electronic device to the second USB interface of the electronic device, the state of the second CC pin in the second USB interface changes, so that the changed state is the state when the otg device is connected to the second USB interface. Since the first USB interface of the electronic device is not connected to the first other electronic device, the state of the first CC pin in the first USB interface is not changed, and the state of the first pin is not connected to the first other electronic device. Therefore, if the CPU of the electronic device determines that the current first USB interface is not connected to the first other electronic device and the second other electronic device connected to the second USB interface is an otg device by detecting the state of the first CC pin in the first USB interface and the state of the second CC pin in the second USB interface, the CPU controls the first switch on the first line to be turned off, the second switch on the second line to be turned on, and the third switch on the third line to be turned off, and triggers the first otg loading process, so that the otg device can normally operate after being connected to the electronic device. Fig. 4 is a schematic circuit structure diagram of an electronic device according to some embodiments of the present application. As shown in fig. 4, when the CPU of the electronic device determines that the first USB interface is not connected to the first other electronic device currently, and the second other electronic device connected to the second USB interface is an otg device, the CPU controls USB3.0SWITCH × 2 to be turned on, USB2.0 SWITCH1 to be turned off, and USB2.0 SWITCH2 to be turned off, that is, controls the electronic device to interact with the second other electronic device in the operating mode 1.

Taking the above as an example, after the user disconnects the second other electronic device from the second USB interface of the electronic device, the state of the second CC pin included in the second USB interface is changed, so that the changed state is the state when the otg device is not connected to the second USB interface. Since the first USB interface of the electronic device is not connected to the first other electronic device, the state of the first CC pin in the first USB interface is not changed, and the state of the first pin is still the state of the first other electronic device. Therefore, if the CPU of the electronic device determines that the second electronic device connected to the second USB interface is currently removed by detecting the state of the first CC pin in the first USB interface and the state of the second CC pin in the second USB interface, the CPU keeps the first switch on the first line open, the second switch on the second line closed, and the third switch on the third line open, and triggers the otg unloading process. As shown in fig. 4, when the CPU of the electronic device determines that the second other electronic device connected to the current second USB interface is removed, the CPU controls USB3.0SWITCH × 2 to be on, USB2.0 SWITCH1 to be off, and USB2.0 SWITCH2 to be off, that is, controls the electronic device to resume the operation mode 1 to the default mode.

For example, if the second other electronic device is a dp device, when the user connects the second other electronic device to the second USB interface of the electronic device, the state of the second CC pin in the second USB interface changes, so that the changed state is the state when the dp device is connected to the second USB interface. Since the first USB interface of the electronic device is not connected to the first other electronic device, the state of the first CC pin in the first USB interface is not changed, and the state of the first pin is not connected to the first other electronic device. Therefore, if the CPU of the electronic device determines that the first USB interface is not connected with the first other electronic device currently and the second other electronic device connected with the second USB interface is a dp device by detecting the state of the first CC pin in the first USB interface and the state of the second CC pin in the second USB interface, the CPU controls the first switch on the first line to be turned off, the second switch on the second line to be turned on, the third switch on the third line to be turned off, and triggers the second otg loading process to implement transmission of the PD protocol, and completes dp event triggering, so that data sent by the electronic device can be acquired after the dp device is connected with the electronic device conveniently. Fig. 4 is a schematic circuit structure diagram of an electronic device according to some embodiments of the present application. As shown in fig. 4, when the CPU of the electronic device determines that the first USB interface is not connected to the first other electronic device currently, and the second other electronic device connected to the second USB interface is a dp device, the CPU controls USB3.0SWITCH × 2 to be on, USB2.0 SWITCH1 to be off, and USB2.0 SWITCH2 to be off, that is, controls the electronic device to interact with the dp device in the operating mode 1.

Taking the above as an example, after the user disconnects the second other electronic device from the second USB interface of the electronic device, the state of the second CC pin included in the second USB interface is changed, so that the changed state is the state when the dp device is not connected to the second USB interface. Since the first USB interface of the electronic device is not connected to the first other electronic device, the state of the first CC pin in the first USB interface is not changed, and the state of the first pin is still the state of the first other electronic device. Therefore, if the CPU of the electronic device determines that the second electronic device connected to the second USB interface is currently removed by detecting the state of the first CC pin in the first USB interface and the state of the second CC pin in the second USB interface, the CPU keeps the first switch on the first line open, the second switch on the second line closed, and the third switch on the third line open, and triggers the otg unloading process. As shown in fig. 4, when the CPU of the electronic device determines that the second other electronic device connected to the current second USB interface is removed, the CPU controls USB3.0SWITCH × 2 to be on, USB2.0 SWITCH1 to be off, and USB2.0 SWITCH2 to be off, that is, controls the electronic device to resume the operation mode 1 to the default mode.

The working mode 2 and the connection condition corresponding to the working mode are as follows: the first USB interface of the electronic equipment is connected with first other electronic equipment, the second USB interface of the electronic equipment is not connected with second other electronic equipment, and the type of the first other electronic equipment is otg equipment. It will be appreciated that this mode of connection is the case where the electronic device interacts only with the first other electronic device. In this connection situation, the on-off conditions of the lines of the electronic device are that the first switch on the first line is closed, the second switch on the second line is closed, and the third switch on the third line is open, that is, the third line is not powered, and the first line and the second line are powered on, so that in the working mode 2, the first other electronic device connected to the first USB interface can interact with the CPU through the multi-channel converter based on the USB2.0 protocol.

For example, if the first other electronic device is an otg device, after the user connects the first other electronic device with the first USB interface of the electronic device, the state of the first CC pin in the first USB interface changes, so that the changed state is the state when the otg device is connected to the first USB interface. Since the second USB interface of the electronic device is not connected to a second other electronic device, the state of the second CC pin in the second USB interface is not changed, and the state of the second pin is not connected to the second other electronic device. Therefore, if the CPU of the electronic device determines that the first other electronic device connected to the first USB interface is an otg device and the second USB interface is not connected to the second other electronic device by detecting the state of the second CC pin in the second USB interface and the state of the first CC pin in the first USB interface, the CPU controls the first switch on the first line to be closed, keeps the second switch on the second line to be closed and the third switch on the third line to be open, and triggers the first otg loading process, so that the otg device can normally operate after being connected to the electronic device. As shown in fig. 4, when the CPU of the electronic device determines that the second other electronic device is not connected to the second USB interface currently, and the first other electronic device connected to the first USB interface is an otg device, the CPU controls USB3.0SWITCH × 2 to be on, USB2.0 SWITCH1 to be on, and USB2.0 SWITCH2 to be off, that is, controls the electronic device to interact with the first other electronic device in the operating mode 2.

Taking the above as an example, after the user disconnects the first other electronic device from the first USB interface of the electronic device, the state of the first CC pin included in the first USB interface is changed, so that the changed state is the state when the otg device is not connected to the first USB interface. And because the second USB interface of the electronic device is not connected with the second other electronic device, the state of the second CC pin in the second USB interface is not changed, and the state of the second pin is still the state of the second other electronic device. Therefore, if the CPU of the electronic device determines that the first other electronic device connected to the first USB interface is currently removed by detecting the state of the second CC pin in the second USB interface and the state of the first CC pin in the first USB interface, the CPU controls the first switch on the first line to be turned off, keeps the second switch on the second line closed and the third switch on the third line open, and triggers the otg unloading process. As shown in fig. 4, when the CPU of the electronic device determines that the first other electronic device connected to the current first USB interface is removed, the CPU controls USB3.0SWITCH × 2 to be on, USB2.0 SWITCH1 to be off, and USB2.0 SWITCH2 to be off, that is, controls the electronic device to resume the operation mode 2 to the default mode.

The working mode 3 and the connection condition corresponding to the working mode are as follows: the first USB interface of the electronic equipment is connected with first other electronic equipment, the second USB interface of the electronic equipment is connected with second other electronic equipment, the type of the first other electronic equipment is otg equipment, and the type of the second other electronic equipment is otg equipment. It will be appreciated that this mode of connection is the case where the electronic device interacts with both the first further electronic device and the second further electronic device. Under the connection condition, the on-off condition of each line of the electronic equipment is that the first switch on the first line is closed, the second switch on the second line is opened, the third switch on the third line is closed, namely the second line is not electrified, and the first line and the third line are electrified, so that under the working mode 3, the first other electronic equipment and the second other electronic equipment can interact with the CPU through the multi-channel converter based on the USB2.0 protocol, and the dp equipment and the otg equipment can interact with the electronic equipment at the same time.

For example, after the user connects the first other electronic device to the first USB interface of the electronic device first, the state of the first CC pin in the first USB interface changes, so that the changed state is the state when the first USB interface is connected to the otg device, and the CPU of the electronic device determines that the first other electronic device connected to the first USB interface is currently the otg device by detecting the state of the first CC pin in the first USB interface, and controls the first SWITCH on the first line to be closed, keeps the second SWITCH on the second line to be closed, and controls the third SWITCH on the third line to be open, that is, controls the USB3.0SWITCH × 2, the USB2.0 SWITCH1, and the USB2.0 SWITCH2 shown in fig. 4 to SWITCH the first otg loading process, so that the first other electronic device can normally operate after being connected to the electronic device. It will be appreciated that the control electronics transition from the default mode to the operating mode 2. Then, after the user connects the second other electronic device to the second USB interface of the electronic device, the state of the second CC pin in the second USB interface changes, so that the changed state is the state when the second USB interface is connected to the otg device, and the CPU of the electronic device determines that the second other electronic device connected to the second USB interface is the otg device by detecting the state of the second CC pin in the second USB interface, and then keeps the first SWITCH on the first line closed, and controls the second SWITCH on the second line to be opened, and the third SWITCH on the third line to be closed, that is, controls the USB3.0SWITCH 2 SWITCH, the USB2.0 SWITCH1 to be opened, and the USB2.0 SWITCH2 to be opened, and triggers the first otg loading process, so that the second other electronic device can normally operate after being connected to the electronic device. It will be appreciated that the control electronics transition from operating mode 2 to operating mode 3.

For any example, after the user first connects the second electronic device to the second USB interface of the electronic device, the CPU of the electronic device determines that the second electronic device connected to the second USB interface is an otg device by detecting the state of the second CC pin in the second USB interface, and then controls the first SWITCH on the first line to be turned off, the second SWITCH on the second line to be turned on, and the third SWITCH on the third line to be turned off, that is, the USB3.0SWITCH × 2, the USB2.0 SWITCH1, and the USB2.0 SWITCH2 shown in fig. 4 are controlled to be turned on, and the first otg loading process is triggered, so that the second electronic device can normally operate after being connected to the electronic device. It will be appreciated that the control electronics transition from the default mode to operating mode 1. Then, after the user connects the first other electronic device with the first USB interface of the electronic device, the CPU of the electronic device determines that the first other electronic device connected to the first USB interface is an otg device by detecting the state of the first CC pin in the first USB interface, and then controls the first SWITCH on the first line to be closed, and controls the second SWITCH on the second line to be opened, and controls the third SWITCH on the third line to be closed, that is, controls the USB3.0SWITCH 2 SWITCH, the USB2.0 SWITCH1 to be opened, and the USB2.0 SWITCH2 to be opened, as shown in fig. 4, and triggers the first otg loading process, so that the first other electronic device can normally operate after being connected to the electronic device. It will be appreciated that the control electronics transition from operating mode 1 to operating mode 3.

Taking the above as an example, after the user disconnects the first other electronic device from the first USB interface of the electronic device, the state of the first CC pin included in the first USB interface is changed, so that the changed state is the state when the otg device is not connected to the first USB interface. And because the second USB interface of the electronic device is still connected with the second other electronic device, the state of the second CC pin in the second USB interface is not changed, and the state of the second pin is still connected with the otg device. Therefore, the CPU of the electronic device determines that the first other electronic device connected to the first USB interface is currently removed by detecting the state of the second CC pin in the second USB interface and the state of the first CC pin in the first USB interface, and then controls the first SWITCH on the first line to be opened, the second SWITCH on the second line to be closed, and the third SWITCH on the third line to be opened, that is, controls USB3.0SWITCH 2 on, USB2.0 SWITCH1 off, and USB2.0 SWITCH2 off shown in fig. 4, and triggers the otg offload process to disconnect the first other electronic device from the CPU. It will be appreciated that the control electronics transition from operating mode 3 to operating mode 1. Then, after the user disconnects the second other electronic device from the second USB interface of the electronic device, the state of the second CC pin included in the second USB interface is changed, so that the changed state is the state when the otg device is not connected to the second USB interface, and the state of the first CC pin of the first USB interface is not changed. Therefore, the CPU of the electronic device determines that the second electronic device connected to the second USB interface is also removed by detecting the state of the second CC pin in the second USB interface and the state of the first CC pin in the first USB interface, and then keeps the first SWITCH on the first line open, the second SWITCH on the second line closed, and the third SWITCH on the third line open, that is, keeps USB3.0SWITCH 2 on, USB2.0 SWITCH1 off, and USB2.0 SWITCH2 off as shown in fig. 4, and triggers the otg offload process to disconnect the second electronic device from the CPU. It will be appreciated that the control electronics revert from operating mode 1 to the default mode.

Taking the above as an example, after the user disconnects the second other electronic device from the second USB interface of the electronic device, the CPU of the electronic device determines that the second other electronic device connected to the second USB interface is removed currently by detecting the state of the second CC pin in the second USB interface and the state of the first CC pin in the first USB interface, and then keeps the first SWITCH on the first line closed, controls the second SWITCH on the second line to be closed, and controls the third SWITCH on the third line to be opened, that is, controls USB3.0SWITCH × 2 on, USB2.0 SWITCH1 on, and USB2.0 SWITCH2 off as shown in fig. 4, and triggers the otg unloading procedure to disconnect the second other electronic device from the CPU. It will be appreciated that the control electronics transition from operating mode 3 to operating mode 2. Then, after the user disconnects the first other electronic device from the first USB interface of the electronic device, the CPU of the electronic device determines that the first other electronic device connected to the first USB interface is also removed by detecting the state of the second CC pin in the second USB interface and the state of the first CC pin in the first USB interface, and then controls the first SWITCH on the first line to open, and keeps the second SWITCH on the second line to close, and the third SWITCH on the third line to open, that is, the switches shown in fig. 4 keep USB3.0SWITCH × 2 on, USB2.0 SWITCH1 off, and USB2.0 SWITCH2 off, and triggers an otg unloading procedure to disconnect the first other electronic device from the CPU.

For example, after the user connects the first other electronic device to the first USB interface of the electronic device first, the state of the first CC pin in the first USB interface changes, so that the changed state is the state when the first USB interface is connected to the otg device, and the CPU of the electronic device determines that the first other electronic device connected to the first USB interface is currently the otg device by detecting the state of the first CC pin in the first USB interface, and controls the first SWITCH on the first line to be closed, keeps the second SWITCH on the second line to be closed, and controls the third SWITCH on the third line to be open, that is, controls the USB3.0SWITCH × 2, the USB2.0 SWITCH1, and the USB2.0 SWITCH2 shown in fig. 4 to SWITCH the first otg loading process, so that the first other electronic device can normally operate after being connected to the electronic device.

Then, after the user connects a second other electronic device with a second USB interface of the electronic device, the state of a second CC pin in the second USB interface is changed, so that the changed state is the state when the second USB interface is connected with a dp device, the CPU of the electronic equipment determines that the second other electronic equipment connected with the current second USB interface is dp equipment by detecting the state of a second CC pin in the second USB interface, keeping the first switch on the first line closed, controlling the second switch on the second line to be opened and the third switch on the third line to be closed, namely, the control USB3.0SWITCH x 2 off, USB2.0 SWITCH1 on, USB2.0 SWITCH2 on shown in fig. 4, and triggers a second otg loading flow to realize the transmission of the PD protocol, completes dp event triggering, therefore, the dp device can conveniently acquire the data sent by the electronic device after being connected with the electronic device. It will be appreciated that the control electronics transition from operating mode 2 to operating mode 4.

For example, when the user first connects the second electronic device to the second USB interface of the electronic device, the CPU of the electronic device determines that the second electronic device connected to the second USB interface is a dp device by detecting the state of the second CC pin in the second USB interface, and then controls the first SWITCH on the first line to be open, the second SWITCH on the second line to be closed, and the third SWITCH on the third line to be open, that is, controls USB3.0SWITCH 2 to be open, USB2.0 SWITCH1 to be closed, and USB2.0 SWITCH2 to be closed as shown in fig. 4, and triggers the second otg loading process to implement transmission of the PD protocol, complete dp event triggering, so that the dp device can acquire data sent by the electronic device after being connected to the electronic device. It will be appreciated that the control electronics transition from the default mode to operating mode 1. Then, after the user connects the first other electronic device with the first USB interface of the electronic device, the CPU of the electronic device determines that the first other electronic device connected to the first USB interface is an otg device by detecting the state of the first CC pin in the first USB interface, and then controls the first SWITCH on the first line to be closed, and controls the second SWITCH on the second line to be opened, and controls the third SWITCH on the third line to be closed, that is, controls the USB3.0SWITCH 2 SWITCH, the USB2.0 SWITCH1 to be opened, and the USB2.0 SWITCH2 to be opened, as shown in fig. 4, and triggers the first otg loading process, so that the first other electronic device can normally operate after being connected to the electronic device.

And because the second USB interface of the electronic device is still connected with second other electronic devices, the state of the second CC pin in the second USB interface is not changed, and the state of the second pin is still connected with dp devices. Therefore, the CPU of the electronic device determines that the first other electronic device connected to the first USB interface is currently removed by detecting the state of the second CC pin in the second USB interface and the state of the first CC pin in the first USB interface, and then controls the first SWITCH on the first line to be opened, the second SWITCH on the second line to be closed, and the third SWITCH on the third line to be opened, that is, the controls USB3.0SWITCH × 2 on, USB2.0 SWITCH1 off, and USB2.0 SWITCH2 off shown in fig. 4, and triggers the otg offload procedure to disconnect the first other electronic device from the CPU. It will be appreciated that the control electronics transition from operating mode 4 to operating mode 1. Then, after the user disconnects the second other electronic device from the second USB interface of the electronic device, the state of the second CC pin included in the second USB interface is changed, so that the changed state is the state when the dp device is not connected to the second USB interface, and the state of the first CC pin of the first USB interface is not changed.
