Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the 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.

The electronic device for executing the information processing method used in the present application may be an external device that connects the processing device and the input device, or the input device may have two signal transmission paths between the electronic device and the processing device, and transmit different signals.

As shown in fig. 1, a flowchart of embodiment 1 of an information processing method provided by the present application is applied to an electronic device, where the electronic device is connected to a processing device, and the method includes the following steps:

step S101: obtaining a first trigger signal;

and under the condition that the processing equipment is in the first mode or the second mode, the obtained trigger signal is a first trigger signal, and the first trigger signal is used for triggering the processing equipment to be switched into the third mode.

The first trigger signal is generated based on a trigger operation, and the trigger operation may be a trigger operation executed on the input device or a trigger operation executed on an input structure of the electronic device.

As an example, the user presses an enter key on a keyboard, and based on the key trigger operation, a first trigger signal is generated.

Step S102: if the connected processing device is in a first mode, transmitting a first switching signal to the processing device through a first path in response to the first trigger signal, so that the processing device can be switched from the first mode to a third mode;

the electronic equipment and the processing equipment are provided with two paths for transmitting signals, namely a first path and a second path, wherein the first path and the second path are different.

And if the connected processing equipment is in the first mode, responding to the first trigger signal, and transmitting a first switching signal to the processing equipment through a first path between the electronic equipment and the processing equipment.

The first switching signal is a signal for triggering the processing device to switch to the third mode, and the processing device can switch from the first switching mode to the third mode after receiving the first switching signal.

Step S103: if the connected processing device is in a second mode, a second switching signal is transmitted to the processing device over a second path in response to the first trigger signal, such that the processing device can switch from the second mode to the third mode.

Wherein the power consumption of the first mode is lower than the power consumption of the third mode, and the power consumption of the second mode is lower than the power consumption of the third mode.

For example, the processing device is in a sleep mode in which the first mode and the second mode are different modes, and the processing device is in a normal operation mode in which it can receive signals from other devices connected thereto.

And if the connected processing equipment is in the second mode, responding to the first trigger signal and transmitting a second switching signal to the processing equipment through a second channel between the electronic equipment and the processing equipment.

In a specific implementation, when the processing device is in the first mode, the first path between the processing device and the electronic device is capable of transmitting signals, and when the processing device is in the second mode, the first path between the processing device and the electronic device is not capable of transmitting signals.

The second switching signal is a signal for triggering the processing device to switch to the third mode, and the processing device can switch from the second switching mode to the third mode after receiving the second switching signal.

If the processing device further performs mode switching, a transmission path for transmitting a switching signal between the electronic device and the processing device is correspondingly adjusted.

Specifically, if it is determined that the processing device is switched from the first mode to the second mode, the transmission of a first switching signal to the processing device through a first path is prohibited, and a second switching signal to the processing device through a second path is controlled;

and if the processing equipment is determined to be switched from the second mode to the first mode, controlling to transmit a first switching signal to the processing equipment through a first path.

In summary, in the information processing method provided in this embodiment, when a connected processing device is in two first modes or second modes with lower power consumption, after receiving a first trigger signal, different switching signals are transmitted to the processing device through different paths based on different modes, so that the processing device is switched to a third mode with higher power consumption. In the scheme, the processing equipment can be switched to the third mode by adopting different modes of responding to the first trigger signal based on the fact that the processing equipment is in different modes.

As shown in fig. 2, a flowchart of embodiment 2 of an information processing method provided by the present application includes the following steps:

step S201: obtaining a first trigger signal;

step S202: if the connected processing device is in a first mode, transmitting a first switching signal to the processing device through a first path in response to the first trigger signal, so that the processing device can be switched from the first mode to a third mode;

step S203: if the connected processing device is in a second mode, transmitting a second switching signal to the processing device through a second path in response to the first trigger signal, so that the processing device can switch from the second mode to the third mode;

steps S201 to 203 are the same as steps S101 to 103 in embodiment 1, and are not described in detail in this embodiment.

Step S204: obtaining a second trigger signal;

the second trigger signal and the first trigger signal only indicate signals at different timings, and the contents/types may be the same or different.

For example, the fact that the contents of the second trigger signal and the first trigger signal are the same means that the same key is triggered; the different contents of the second trigger signal and the first trigger signal refer to signals triggered by different keys.

For example, the second trigger signal and the first trigger signal are of the same type, which means the same type of operation trigger signal, such as signals generated by operating a keyboard or signals generated by operating a mouse;

for example, the second trigger signal and the first trigger signal are different in type, which means that the second trigger signal is not a signal triggered by one type of operation, such as a signal generated by operating a keyboard and a mouse.

Wherein, in case the processing device is in the third mode, the obtained trigger signal is a second trigger signal for triggering the processing device to respond in a manner completely different from the switching mode.

Step S205: transmitting the second trigger signal to the processing device in the third mode over the first path.

Wherein the power consumption of the processing device in the first mode is higher than the power consumption in the second mode.

Specifically, when the processing device is in the second mode, part of the applications are stopped, the processing device is disconnected from the first path of the electronic device, and only the second path is maintained; and in the first mode, only part of the applications are stopped, and the first path and the second path of the processing equipment and the electronic equipment are conducted. Also, the application stopped in the second mode is greater than or equal to the application stopped in the first mode.

And when the processing equipment is in the third mode, the application of the processing equipment runs normally and is conducted with the first channel and the second channel of the electronic equipment.

As an example, the first path is a USB (Universal Serial Bus) Bus, and the second path is a CC (Configuration Channel). When the USB interface is powered off, the first channel is disconnected. In the first mode, the processing device is in a power saving mode, only part of the applications are stopped, only part of the controller is stopped, and the USB interface is kept powered on.

It should be noted that, in the embodiment of the present application, a USB interface is taken as an example for description, but the specific implementation is not limited to this, an interface of another protocol may also be used in the processing device and the electronic device, and when the processing device is in a certain specific mode, the interface cannot perform signal transmission with the electronic device due to power failure or some reason, and when the processing device is in another specific mode, the interface is powered back on or other reasons enable signal transmission with the electronic device.

And after the processing equipment is switched to the third mode, the subsequently received second trigger signal is transmitted through the first channel.

Specifically, after the processing device switches back to the third mode, power is supplied to the USB interface, the USB bus is turned on, and the received trigger signal (the second trigger signal) is transmitted through the USB bus.

The second trigger signal is used to trigger the processing device to respond in a manner completely different from switching to the third mode, and the response is specifically performed for an application running in the processing device.

For example, the second trigger signal is the key value of a space, and the response to the second trigger signal in the processing device is to pause the video being played.

In summary, the information processing method provided in this embodiment further includes: obtaining a second trigger signal; transmitting the second trigger signal to the processing device in the third mode over the first path; wherein the power consumption of the first mode is higher than the power consumption of the second mode. In this scheme, after the processing device switches from the first mode or the second mode to the third mode, the obtained second trigger signal is transmitted to the processing device through the first path, which is used as a default path for transmitting the second trigger signal.

As shown in fig. 3, a flowchart of embodiment 3 of an information processing method provided in the present application, where the method is applied to an electronic device, includes the following steps:

step S301: obtaining a first trigger signal;

Step S302: if the connected processing equipment is in a first mode, responding to the first trigger signal, and transmitting the first switching signal to the processing equipment through a first path corresponding to a first pin, so that the processing equipment can be switched from the first mode to a third mode;

The first pin corresponds to the first channel, and the second pin corresponds to the second channel.

And if the connected processing equipment is in the first mode, responding to the first trigger signal, and transmitting the first switching signal to the processing equipment through the first path corresponding to the first pin.

Step S303: and if the connected processing equipment is in a second mode, responding to the first trigger signal, and transmitting the second switching signal to the processing equipment through a second path corresponding to a second pin, so that the processing equipment can be switched from the second mode to the third mode.

And if the connected processing equipment is in the second mode, responding to the second trigger signal and transmitting the second switching signal to the processing equipment through a second path corresponding to the second pin.

After the first trigger signal is obtained, the corresponding pin is determined according to the mode of the connected processing equipment, and then the pin is transmitted to the processing equipment according to the path corresponding to the pin.

If the interface is a USB-typeC interface, the electronic equipment is connected with the processing equipment through a USB-typeC data line. The USB-typeC interface comprises two paths, wherein the USB bus is used as one path for transmitting signals of a USB bus protocol, and the CC is used as the other path for transmitting signals of other protocols.

Fig. 4 is a schematic system diagram, which includes a processing device 401 and an electronic device 402, where the processing device and the electronic device respectively use a USB-typeC interface, where the interface corresponds to two channels, including a first channel USB-bus and a second channel CC.

Of course, the connection mode between the processing device and the electronic device is not limited to the above.

In a specific implementation, an interface is provided in the electronic device, the interface has a plurality of pins, a specific pin can correspond to both the first path and the second path, and different paths adopt different protocols, so that when responding to the first trigger signal, and when determining different paths, the protocol corresponding to the path is adopted, so that the determined path can transmit a corresponding switching signal.

For example, it is determined that the first path is adopted to transmit the switching signal, and a protocol corresponding to the first path is adopted to transmit the first switching signal; and determining to adopt the second path to transmit the switching signal and adopt a protocol corresponding to the second path to transmit the second switching signal.

In a specific implementation, the electronic device may further include two interfaces, where the first interface has a first pin corresponding to the first path, and the second interface has a second pin corresponding to the second path.

When responding to a first trigger signal, if a target adopts a first path, determining a first pin corresponding to the first path, and sending a first switching signal to the first path through the first pin; and if the target adopts the second path, determining a second pin corresponding to the second path, and sending the second switching signal to the second path through the second pin.

In summary, in an information processing method provided by this embodiment, the transmitting a first switching signal to a processing device through a first path includes: transmitting the first switching signal to processing equipment through a first path corresponding to a first pin; the transmitting a second switching signal to the processing device over a second path includes: transmitting the second switching signal to a processing device through a second path corresponding to a second pin; the second pin and the first pin are different pins of the same interface. In the scheme, based on the first different paths of different pins of the same interface, when the switching signal is transmitted to the processing equipment through the paths, the different switching signals are transmitted to the processing equipment through the paths corresponding to the different pins.

For example, the electronic device is a keyboard and mouse, a microphone, a camera or other devices with functions of collecting input information, and the electronic device and the processing device have two paths, and the two paths can transmit different switching signals.

For example, when a user clicks a certain key on a keyboard, the keyboard detects a trigger operation of the clicked key, and generates a first trigger signal based on the trigger operation.

For example, the same operation may be that both trigger operations are clicking the space bar in the keyboard; the different operation may be that the first trigger operation and the second trigger operation are different keys in the keyboard.

Accordingly, a second trigger signal is generated based on the detected second trigger operation.

Wherein the second trigger signal is the same type of trigger signal as the first trigger signal, or the same trigger signal.

Wherein the same type of trigger signal is generated based on different trigger operations, and the same trigger signal is generated based on the same trigger operation.

step S901: if a first detection signal from the processing equipment is received, determining that the processing equipment is in the first mode;

Wherein the first detection signal is used to detect whether a first path between the processing device and the electronic device (also acting as an input device) is clear.

If the processing device is in the first mode, it needs to maintain the first path to be kept clear, specifically, a first detection signal is generated and sent to the processing device to detect the condition of the first path.

The first detection signal is sent according to an appointed period, and the duration of the specific period may be set according to an actual situation, which is not limited in this embodiment.

If the electronic device can receive the first detection signal from the processing device, it may be determined that the processing device is in the first mode.

It should be noted that the second path may transmit other detection signals, and the detection signal transmitted by the second path is not limited in this application.

Step S902: determining that the processing device is in the second mode if the time for which the first detection signal from the processing device is not received exceeds a time threshold;

the value of the time threshold is a value greater than a transmission period of the first detection signal, for example, 2 times or 5 times of the period, and the specific value of the time threshold is not limited in this application.

When the processing equipment is in the second mode, the first path is disconnected, and the first detection signal is not transmitted.

If the first detection signal from the processing device is not received beyond the time threshold, it indicates that the processing device is not generating the first detection signal any more, that is, the processing device is in the second mode.

Step S903: obtaining a first trigger signal;

step S904: if the connected processing device is in a first mode, transmitting a first switching signal to the processing device through a first path in response to the first trigger signal, so that the processing device can be switched from the first mode to a third mode;

step S905: if the connected processing device is in a second mode, a second switching signal is transmitted to the processing device over a second path in response to the first trigger signal, such that the processing device can switch from the second mode to the third mode.

Steps S903 to 905 are the same as steps S101 to 103 in embodiment 1, and are not described in detail in this embodiment.

In summary, the information processing method provided in this embodiment further includes: determining that the processing device is in the second mode if the time for which the first detection signal from the processing device is not received exceeds a time threshold; and if a first detection signal from the processing equipment is received, determining that the processing equipment is in the first mode. In this scheme, since the processing device generates the first detection signal or does not generate the detection signal when the processing device is in the different mode, the mode in which the processing device is located can be determined based on whether the first detection signal from the processing device is received.

As shown in fig. 10, a flowchart of embodiment 8 of an information processing method provided in the present application, where the method is applied to an electronic device, includes the following steps:

step S1001: if a first detection signal from the processing device is received, determining that the processing device is in the first mode;

step S1001 is the same as step S901 in embodiment 7, and details are not described in this embodiment.

Step S1002: forwarding the first detection signal to a connected input device;

The first detection signal is used for detecting whether a path between the processing device and the input device is unblocked, and the electronic device is arranged between the processing device and the input device, when the mode of the processing device changes, the processing device is powered off and powered back on the USB interface, and the path between the input device and the electronic device is not affected.

Wherein, if receive this processing apparatus's first detected signal, need further to forward this first detected signal to the input device of connection to make this processing apparatus detect whether its connection with input device is unobstructed based on its first detected signal, should connect and include two routes: a first path and a path between the processing device and the input device.

Step S1003: determining that the processing device is in the second mode if the time for which the first detection signal from the processing device is not received exceeds a time threshold;

step S1003 is the same as step S902 in embodiment 7, and details are not described in this embodiment.

Step S1004: generating a second detection signal, and sending the second detection signal to the input device;

wherein the second detection signal and the first detection signal satisfy the same condition.

If the processing device is determined to be in the second mode, the electronic device still needs to detect whether the connection between the electronic device and the input device is smooth.

Specifically, the electronic device generates a second detection signal satisfying the same condition as the first detection signal, and sends the second detection signal to the input device, so as to simulate the connection between the processing device and the input device.

Specifically, the same condition is that the first detection signal is the same as or similar to the second detection signal, and the first detection signal is indistinguishable from the second detection signal as viewed from the input device side and can respond to the two detection signals in the same manner.

Step S1005: obtaining a first trigger signal;

step S1006: if the connected processing device is in a first mode, transmitting a first switching signal to the processing device through a first path in response to the first trigger signal, so that the processing device can be switched from the first mode to a third mode;

step S1007: if the connected processing device is in a second mode, a second switching signal is transmitted to the processing device over a second path in response to the first trigger signal, such that the processing device can switch from the second mode to the third mode.

Steps S1005-1007 are the same as steps S903-905 in embodiment 7, and are not described in detail in this embodiment.

In summary, the information processing method provided in this embodiment further includes: based on determining that the processing device is in the first mode, forwarding the first detection signal to a connected input device; based on determining that the processing device is in the second mode, generating a second detection signal, and sending the second detection signal to the input device, wherein the second detection signal and the first detection signal meet the same condition. In the scheme, if the electronic equipment is connected with the input equipment, after receiving a first detection signal, the electronic equipment forwards the first detection signal to the connected input equipment so as to keep the channel between the processing equipment and the input equipment to be connected; if the processing device is in the second mode, generating a second detection signal meeting the same condition as the first detection signal so as to keep the channel between the electronic device and the input device connected, so as to ensure that the first trigger signal input by the input device can be obtained by the electronic device.

As shown in fig. 11, a flowchart of embodiment 9 of an information processing method provided in the present application, where the method is applied to an electronic device, includes the following steps:

step S1101: obtaining a first trigger signal;

step S1101 is the same as step S101 in embodiment 1, and details are not described in this embodiment.

Step S1102: transmitting a first switching signal based on a first path in response to the first trigger signal;

the electronic device responds to the first trigger signal by default and sends a switching signal through the first path.

Specifically, after obtaining the first trigger signal, the first switching signal is sent based on the default first path in response to the first trigger signal.

And after the first switching signal is sent, timing is started, and timing time is obtained to determine whether the notification signal is received through the first channel within a preset time period.

If the processing device can receive the first switching signal through the first path, the processing device switches to the third mode, and after the processing device switches to the third mode, the processing device needs to determine the device connection condition of each interface of the processing device, and the processing device generates a notification signal and sends the notification signal to each interface of the processing device to obtain device information of devices connected to each interface, so that an enumeration process of the processing device in switching to the third mode is realized.

Wherein, if the processing device is capable of receiving the first switching signal through the first path, the processing device is capable of switching to the third mode and generating the notification signal within a preset time period after transmitting the first switching signal.

Step S1103: if a notification signal is received through a first path within a preset time period after the transmission, determining that the processing device is in a first mode;

if the notification signal is received through the first path within a preset time period after the transmission, it is known that the first trigger signal transmitted through the first path can be transmitted to the processing device, and the processing device is in the first mode and can receive the first trigger signal through the first path.

And if the notification signal sent by the processing device through the first path is received, the processing device is indicated to respond to the first switching signal and has switched to the third mode.

Step S1104: and if the notification signal is not received through the first channel within a preset time period after the sending, determining that the processing equipment is in the second mode, and sending a second switching signal to the processing equipment through the second channel.

If the notification signal is not received through the first path within a preset time period after the transmission, it indicates that the processing device does not respond to the first switching signal, and it may be determined that the processing device is in the second mode.

Accordingly, a second switching signal is sent to the processing device using the second path to cause the processing device to switch from the second mode to the third mode.

If the second switching signal is sent to the processing equipment through the second path, the notification signal sent by the processing equipment through the first path is received within a preset time period, the processing equipment is determined to be switched to the third state, and the first path is continuously adopted to send the second trigger signal subsequently.

In a specific implementation, if the first trigger signal is obtained again, the first trigger signal is still sent through the first path.

In summary, the information processing method provided in this embodiment includes: transmitting a first switching signal based on a first path in response to the first trigger signal; if a notification signal is received through a first path within a preset time period after the transmission, determining that the processing device is in a first mode; and if the notification signal is not received through the first channel within a preset time period after the sending, determining that the processing equipment is in the second mode, and sending a second switching signal to the processing equipment through the second channel. In the scheme, a switching signal is sent through a first path in response to a first trigger signal, whether a notification signal is received through the first path within a preset time period after sending is determined, the processing equipment is in a first mode or a second mode, and if the processing equipment is in the second mode, a second switching signal is sent to the processing equipment through the second path, so that the switching signal can be sent to the processing equipment.

As shown in fig. 12, a flowchart of an embodiment 10 of an information processing method provided in the present application is applied to an electronic device, and the method includes the following steps:

step S1201: obtaining a first trigger signal;

step S1201 is the same as step S101 in embodiment 1, and details are not described in this embodiment.

Step S1202: if the connected processing device is in a first mode, responding to the first trigger signal, and transmitting the first trigger signal as a first switching signal to the processing device through a first path, so that the processing device can be switched from the first mode to a third mode;

and responding to the first trigger signal if the processing equipment is in the first mode.

And if the first trigger signal and the first path adopt the same protocol, the first trigger signal is used as a first switching signal and is transmitted to the processing equipment through the first path.

Wherein the first trigger signal and the first switching signal are the same signal on different devices.

The protocol adopted by the first trigger signal may be a UBS bus protocol or the like.

Step S1203: if the connected processing equipment is in a second mode, responding to the first trigger signal, and generating a second switching signal according to the first trigger signal;

the second path and the first trigger signal adopt different protocols, when the processing equipment is in the second mode, and when the processing equipment responds to the first trigger signal, the switching signal needs to be sent through the second path.

Specifically, a second switching signal is generated according to the first trigger signal.

The second path is a configuration channel, and configuration events can be transmitted on the second path, and correspondingly, the USB bus protocol information is converted into the configuration events.

It should be noted that, a new event type support is added to the USB PD (USB Power Delivery) 3.1 Specification (Universal Serial Bus Power Delivery Specification, Revision 3.1, May 2021), and includes: power State Change (Power State Change), Power button Press/Release (Power button Press/Release), Controller Initiated wake up (Controller Initiated wake). The new PD specification described above is supported by a Type-C host. Therefore, the host has an opportunity to be awakened by a specific event on the CC channel on the Type-C port from the outside under the situation of keeping super power saving (the USB controller is closed, and the USB port power is closed).

In the present application, the received first trigger signal is converted into a standard wake-up event in the form of a Power button Press/Release (Power button Press/Release) or a Controller Initiated wake-up (Controller Initiated wake) specified in the UBS PD3.1 specification.

Accordingly, in the present application, after the processing device receives the second switching signal, it determines that the second switching signal is a standard wake-up event, and wakes up a structure of a processor controller and the like of the processing device that is in a sleep mode in the super power saving mode, where the structure of the controller and the like is in the sleep mode when the processing device is in the second mode, and no longer controls power supply to the first path portion in the interface, so that the first path may not transmit a signal.

Step S1204: transmitting a second switching signal to the processing device over a second path such that the processing device can switch from the second mode to the third mode.

After the second switching signal is generated, the second switching signal conforms to the protocol of the second path, and the second switching signal is transmitted to the processing device through the second path, so that the processing device receives the second switching signal and switches to the third mode.

In summary, the information processing method provided in this embodiment further includes: based on the processing device being in a first mode, sending the first trigger signal as a first switching signal to a processing device; and generating a second switching signal according to the first trigger signal based on the fact that the connected processing equipment is in the second mode. In the scheme, based on the fact that the processing equipment is in the first mode, the first trigger signal is directly used as the first switching signal and sent to the processing equipment, and other processing is not needed; based on the second mode of the processing equipment, the second switching signal is generated according to the first trigger signal, the switching function is enabled, different switching signals are transmitted aiming at different channels, and the processing equipment is ensured to be capable of receiving the switching signal and switching to the third mode.
