technical field

The invention relates to the field of electronic technology, in particular to a USB wake-up method, device, circuit, notebook computer, equipment and medium.

Background technique

Laptops usually use an embedded controller hanging under the CPU bus to help the laptop manage low-speed peripherals (such as touchpads, matrix keyboards, etc.), and control the sleep and wake-up of the laptop through the working status of the peripherals, so as to Implement power management functions. By default, when the notebook computer is turned on and in an active state, when the lid is closed, the lid closure sensor (usually a Hall sensor) outputs a lid closure signal, and the embedded controller will put the notebook computer into a sleep state after receiving the signal. For a notebook computer in a sleep state, when the embedded controller monitors the event of opening the cover, the action of the USB peripheral, etc., it will control the power supply through the wake-up signal and wake up with the bridge chip or the bus of the CPU.

But for the prior art solution, after the notebook is closed, various wake-up sources are allowed to wake up the computer, including peripherals of the USB interface (such as a wired mouse, a wireless mouse). Therefore, it is easy to accidentally touch a USB peripheral (most typically a mouse), and inadvertently wake up the notebook computer, leaving the notebook computer in an unnecessary active state. Due to the high power consumption of the active state, the battery power is quickly consumed. And it is difficult for the user to find this state and there is no way to correct it.

Of course, the existing technical solution can also manually disable the USB wake-up in the configuration interface of the Basic Input Output System (BIOS), but this will bring obvious inconvenience, and cannot meet the need for USB wake-up when the laptop is opened. , it is unavoidable that some gains outweigh the losses.

FIG. 1 is one of the schematic flowcharts of the USB wake-up method provided by the present invention. As shown in FIG. 1 , the USB wake-up method provided by the embodiment of the present invention includes: Step 101 , when it is determined that the notebook computer is in a sleep state, receiving a first signal sent by a USB controller.

Wherein, the first signal is generated when the USB controller of the notebook computer monitors that the USB peripheral device generates a touch operation. The USB peripheral is one or more of a wired mouse, a wireless mouse, a wired keyboard, and a wireless keyboard connected to a notebook computer through a USB interface.

It should be noted that the server peripheral configuration identification method provided by the embodiment of the present invention is executed by a server peripheral configuration identification device set in the server.

In the application scenario of the USB wake-up method provided by the embodiment of the present application, the wake-up process of the notebook computer is usually realized by the embedded controller of the notebook computer, and whether to wake up the system is determined by adding the judgment of whether the notebook computer is closed or not. When the notebook is closed, the USB peripherals are not allowed to wake up the computer. When the notebook is opened, it is allowed to wake up the USB peripheral to wake up the computer. In this way, the effect of automatically configuring whether to allow USB wake-up is realized according to whether the lid is closed or not.

It should be noted that USB peripherals refer to other devices except host hardware devices. The above-mentioned devices are all connected to the USB controller of the notebook computer through the USB interface, so that when the USB controller monitors that the USB peripherals are active There are signals connected to the embedded controller.

Exemplarily, the USB peripheral connected to the notebook computer through the USB interface can be a mouse, so as to trigger a wake-up action by positioning the cursor on the current screen and operating the screen elements at the position passed by the cursor through the button and wheel device.

Wherein, the mouse may be a wired mouse for wired communication through a data cable with a USB interface, or a wireless mouse for wireless communication with a wireless transceiver with a USB interface, which is not specifically limited in this embodiment of the present invention.

Exemplarily, the USB peripheral connected to the notebook computer through the USB interface can be a keyboard, so as to send commands to the computer and trigger a wake-up action when inputting data by inputting English letters, Chinese characters, numbers, punctuation marks, etc. into the computer.

Wherein, the keyboard may be a wired keyboard for wired communication through a data cable with a USB interface, or a wireless keyboard for wireless communication with a wireless transceiver with a USB interface, which is not specifically limited in this embodiment of the present invention.

Specifically, in step 101, when the USB wake-up device set on the embedded controller determines that the notebook computer is already in a sleep state according to the operation information of each component in the notebook computer, it receives a USB The first signal sent when a peripheral is active.

Wherein, the first signal has different action attributes according to different touch actions performed by the USB peripheral in an active state.

For example, when the USB peripheral is in an active state and is continuously touched multiple times, or after being continuously touched for a period of time, it is determined that the attribute corresponding to the first signal in this case is an application for waking up the system.

However, when the USB peripheral is in an inactive state, or only one touch occurs when it is in an active state, it is determined that the first signal does not have the property of waking up the system in this case.

Step 102: If it is determined that the first signal is a wake-up signal, receive power supply state detection information fed back by the first detection module.

Wherein, the power supply state detection information is obtained by the first detection module judging whether the power adapter is in place to supply power to the notebook computer, and the corresponding power supply mode when the power adapter is in place It is powered by an external power supply, and the corresponding power supply mode is powered by an internal battery when the power adapter is not in place.

It should be noted that the first detection module is used to detect the power supply mode of the notebook computer based on whether the power adapter is connected.

Specifically, in step 102, the USB wake-up device provided on the embedded controller further judges whether to intercept this wake-up according to the attribute of the first signal:

If the attribute corresponding to the first signal is an application to wake up the system, then if the first detection module is inquired about the power supply mode of the notebook computer, and the power supply status detection information fed back by the first detection module is obtained.

If the attribute corresponding to the first signal is not an application for waking up the system, no operation is required and the original sleep state is maintained.

Wherein, the power supply identification carried in the power supply state detection information is used to indicate whether the power adapter of the notebook computer is being connected. If it is connected, the power supply identification is an external power supply to indicate that the notebook computer is currently powered externally through the power adapter. On the contrary, the power supply flag is powered by the internal battery to indicate that the notebook computer currently has an internal power supply circuit for internal power supply, and the wake-up behavior monitored at this time needs to be further intercepted.

Step 103: When it is determined that the power supply identification carried in the power supply state detection information is powered by an internal battery, query the cover state detection information of the notebook computer by sending a query request to the second detection module.

Wherein, the cover state detection information is the relative positional relationship between the screen surface and the keyboard surface of the notebook computer collected by the second detection module in response to the query request.

It should be noted that the second detection module is used to detect whether the screen surface of the notebook computer is close to the keyboard surface, that is, whether the notebook computer is in the closed state, or the user's operation intention on the notebook computer is to close it. build.

Specifically, in step 103, the USB wake-up device set on the embedded controller further judges whether to start the lid closing detection according to the power supply state detection information:

If the power supply indicator carried in the power supply status detection information indicates that the internal battery is powered, it means that the notebook computer is currently powered only by the internal battery, and its use scenario tends to be carried by the user to carry the notebook computer and perform related operations. The action is more vigilant, by querying the relative positional relationship between the screen surface and the keyboard surface of the notebook computer from the second detection module, and obtaining the cover state detection information fed back by the second detection module.

Wherein, the lid state detection information carries a lid-closed flag to indicate whether the notebook computer is in the lid-closed state, or the intention of the user to operate the notebook computer is to close the lid. The lid closing flag has a logical value. If the lid closing flag is a true value, the laptop is currently in the lid closing state, and the wake-up behavior monitored at this time needs to be intercepted. Otherwise, the lid closing flag is a false value, and the laptop is currently in the closed state. In the state of opening the cover, there is no need to intercept the wake-up behavior monitored at this time.

Step 104, when it is determined that the lid closing flag carried in the cover state detection information fed back by the second detection module is true, send a second signal to the power supply circuit for the power supply circuit to use according to the second The signal updates the notebook computer from the sleeping state to the working state.

It should be noted that the power supply circuit adopts a switching power supply circuit, which is mainly composed of electronic components such as power control chips, field effect transistors, capacitors, resistors and inductors, and is used to perform corresponding functions when the notebook computer is in different states. Power supply mode to supply power to the components involved.

Among them, notebook computers usually have four operating states:

(1) Working state refers to the full-featured state of a system, which is within the capability of the system's software and hardware. As long as any touch action occurs, the notebook computer will immediately have corresponding feedback.

(2) Sleep state, the central processing unit (Central Processing Unit, CPU) stops executing instructions, all programs in the background are suspended, and the things in the memory remain in the memory as they are. Before the system is woken up, if the power is cut off, all the information in the memory will be lost, because the information in the memory requires a small amount of power to maintain. After the system wakes up, all system states return to what they were before sleep. All previously open application windows remain in place and their contents remain unchanged.

(3) Sleep state, most of the features of the sleep state and the sleep state are the same, the difference is that the information left in the memory in the sleep state is written to the hard disk as it is, and the system itself enters a zero power consumption state after the sleep state is completed. When the system is woken up, the memory image in the hard disk is loaded into the memory as it is, and the system resumes operation.

(4) In the shutdown state, it will enter the zero power consumption mode, and all the data in the memory will be cleared.

Specifically, in step 104, the USB wake-up device arranged on the embedded controller further judges whether to wake up the system according to the cover state detection information:

If the lid state detection information carries a false value of the lid closing flag, it means that the notebook computer is currently in the open state, or the user’s intention to operate the notebook computer is to open the lid, then send a second signal to the power supply circuit to wake up the notebook computer. system.

The power supply circuit receives and responds to the second signal, performs pulse modulation on the input power supply, realizes the functions of power supply conversion, automatic voltage stabilization and output adjustable voltage. Therefore, the notebook computer is converted from the power supply mode of the original sleep state to the power supply mode corresponding to the working state.

If the cover status detection information carries the cover closing flag as true, it means that the laptop is currently in the cover closed state, or the user’s intention to operate the laptop is to close the cover, then determine to intercept the currently monitored peripheral wake-up operation , still maintaining the original sleep state.

In the embodiment of the present invention, when the notebook computer is in a sleep state, after intercepting the first signal for applying to wake up the system monitored by the USB controller to the USB peripheral, the first detection information of the power supply status fed back by the first detection module is sent to the notebook computer. Make a preliminary judgment based on the usage scenario, determine whether it uses the power supply circuit for internal battery power supply, and then perform different processing according to the cover status detection information fed back by the second detection module, and decide whether to wake up the system. Realize no additional manual configuration of the USB wake-up switch, and can automatically configure the peripheral wake-up based on the power supply mode and the closed state of the notebook computer, so that the USB peripheral cannot wake up the sleeping notebook normally when the internal battery is powered and the cover is closed computer.

On the basis of any of the above embodiments, the cover state detection information at least includes the angle formed at the hinge between the outer edge of the screen surface and the keyboard surface, and/or, the outer edge of the screen surface The distance between the edge and the outer edge of the keyboard face.

Specifically, the USB wake-up device set on the embedded controller can detect the relative position between the screen surface and the keyboard surface of the notebook computer through the query request sent to the second detection module, and can compare the screen surface and the keyboard surface The angle between the package and the cover status detection information is fed back to the USB wake-up device.

The distance between a certain reference point on the outer edge of the screen surface and the reference point corresponding to the reference point on the outer edge of the keyboard surface can also be packaged into the cover state detection information and fed back to the USB wake-up device.

In the embodiment of the present invention, a query request is sent to the second detection module to receive the cover state detection information fed back by the second detection module, and analyze the distance between the screen surface and the keyboard surface of the notebook computer. Furthermore, according to the angle or distance between the screen surface and the keyboard surface of the notebook computer, the lid closure is judged to determine whether to wake up the system, so as to realize the effect of automatically configuring whether to allow USB wake-up according to whether the lid is closed.

On the basis of any of the above-mentioned embodiments, when it is determined that the power supply identification carried by the power supply state detection information is powered by an internal battery, the notebook computer is queried by sending a query request to the second detection module. After the cover state detection information, it also includes: when it is determined that the angle and/or outer edge distance between the screen surface and the keyboard surface of the notebook computer carried by the cover state detection information is less than or equal to the preset threshold , set the closed lid flag to true, and keep the laptop in a sleep state.

It should be noted that the preset threshold refers to the threshold set for the relative positional relationship between the screen surface and the keyboard surface of the notebook computer, so as to judge the closed state of the notebook computer.

Specifically, the USB wake-up device arranged on the embedded controller can judge from the angle between the screen surface and the keyboard surface of the notebook computer carried by the cover state detection information, if the angle between the two is greater than the preset When the threshold is reached, it means that the laptop is in the open state, or the user intends to open the laptop by operating the laptop, then set the cover closed flag to false.

It can be judged from the outer edge distance between the screen surface and the keyboard surface of the notebook computer carried by the cover state detection information. If the distance between the two is greater than the preset threshold, it means that the notebook computer is in the open state, or If the user intends to operate the notebook computer to open the cover, the lid closing flag is set to false, and the notebook computer is woken up by the second signal. If the distance between the two is less than or equal to the preset threshold, it means that the notebook computer is in the closed state, or the user’s intention to operate the notebook computer is to close the lid, then set the closed cover flag to true to make the notebook computer The computer remains in its original sleep state.

In the embodiment of the present invention, after intercepting the current application wake-up action, according to the cover state detection information fed back by the first detection module, it is determined that the angle and/or outer edge distance between the screen surface and the keyboard surface of the notebook computer are less than or equal to When the threshold is preset, the decision will be closed and the flag logic is true to allow the USB peripheral to wake up the computer. Realize no additional manual configuration of the switch for USB wake-up. It can only judge the closed state according to the angle and distance formed between the two sides of the notebook computer, and combine the judgment results to automatically configure the wake-up of its peripherals, so that it can be closed in the closed state. This makes it impossible for USB peripherals to wake up sleeping laptops normally, and solves the problem that the computer is easily woken up by touching the USB peripherals by mistake after the computer is closed and sleeps. Thereby avoiding unnecessary power consumption and heating after waking up.

On the basis of any of the foregoing embodiments, the preset threshold is 0.

Specifically, the USB wake-up device installed on the embedded controller can set the value of the preset threshold to 0, so as to determine whether the notebook computer is in a completely closed state through threshold comparison.

It can be understood that the value of the preset threshold can also be set to a smaller value slightly greater than 0, so as to determine whether the notebook computer is not fully closed due to a wrong operation under the action intention of the user to close the lid through threshold comparison. Closed state.

In the embodiment of the present invention, the threshold value of the angle or the distance between the screen surface and the keyboard surface of the notebook computer is set to 0 to judge whether the notebook computer is fully closed. Realize no need for additional manual configuration of the switch for USB wake-up, and can only automatically configure the peripheral wake-up according to the closed state determined by the angle and distance between the two sides of the notebook computer.

On the basis of any of the above embodiments, when it is determined that the angle between the screen surface and the keyboard surface of the laptop computer carried by the cover state detection information is less than or equal to the preset threshold, the After the lid closing flag is set to true and the notebook computer is kept in the sleep state, it also includes: if the built-in keyboard on the keyboard surface is monitored for a touch event, the notebook computer is kept in the sleep state .

Specifically, after the notebook computer is closed and in a sleep state, the USB wake-up device arranged on the embedded controller monitors that the built-in keyboard on the keyboard surface applies for wakeup when a touch event occurs, and keeps the notebook computer in the sleep state.

Exemplarily, FIG. 2 is the second schematic flowchart of the USB wake-up method provided by the present invention. As shown in Figure 2, the embodiment of the present invention provides a specific implementation of a USB wake-up method based only on lid closing detection:

In the sleep state, when the embedded controller receives the first signal sent by the USB controller and determines that the signal is a wake-up signal, the embedded controller inquires the first detection module, and according to the mechanism fed back by the first detection module, Cover state detection information is handled differently. If the cover is closed, the system will not be woken up, and if the cover is opened, the system will be woken up.

In the embodiment of the present invention, when a touch event is detected on the built-in keyboard of the notebook computer, the notebook computer is kept in the original sleep state. It can prevent unnecessary power consumption caused by waking up the laptop with its own keyboard due to pressure after closing the lid to sleep.

On the basis of any of the above-mentioned embodiments, if it is determined that the first signal is a wake-up signal, after receiving the power supply state detection information fed back by the first detection module, it further includes: after determining the power supply state detection information, When the carried power supply identification is an external power supply, a second signal is sent to the power supply circuit, so that the power supply circuit updates the notebook computer from the sleeping state to the working state according to the second signal.

Specifically, the USB wake-up device set on the embedded controller performs a priori judgment on whether to start the lid closing detection according to the power supply state detection information:

If the power supply identification carried by the power supply status detection information indicates external power supply, it means that the usage scenario of the notebook computer tends to be that the user is charging the notebook computer. Once a wake-up event occurs, it is considered that the user needs to end the external charging in advance. The monitored wake-up action is more tolerant. As long as the USB peripheral triggers a wake-up event, no matter whether the laptop is closed or not, the original sleep state will switch to the working state.

In the embodiment of the present invention, when the notebook computer is in a sleep state, after intercepting the first signal monitored by the USB controller to the USB peripheral for applying to wake up the system, the power supply state detection information fed back by the second detection module is first sent to the notebook computer. Make a preliminary judgment on the usage scenario, and determine that it directly responds to all wake-up events when it is powered by an external power supply. Realize no additional manual configuration of the USB wake-up switch, and can automatically configure the peripheral wake-up based on the power supply mode of the notebook computer and the closed state, so that the USB peripheral can normally wake up the sleeping notebook computer in the external power supply state.

On the basis of any of the above embodiments, after the first signal sent by the USB controller is received in the case of determining that the notebook computer is in a sleep state, it further includes: if it is determined that the first signal is not a wake-up signal, Put said laptop to sleep.

Specifically, after step 101, if the USB wake-up device provided on the embedded controller determines that the attribute corresponding to the first signal is not an application for waking up the system, it does not need to perform any operation and remains in the original sleep state.

Exemplarily, FIG. 3 is the third schematic flowchart of the USB wake-up method provided by the present invention. As shown in Figure 3, the embodiment of the present invention provides a specific implementation of a USB wake-up method based only on power supply detection and lid closing detection:

The embedded controller first checks whether the power adapter is plugged in through the power supply status detection information fed back by the second detection module. If it is plugged in, the power supply is marked as external power supply. Once the USB peripheral is detected to be active, the system is directly woken up. If the power adapter is not plugged in and the power supply sign is powered by an internal battery, it is necessary to further inquire about the combined cover of the first detection module, and perform different processing according to the cover state detection information fed back by the first detection module. If the cover is closed, the system will not be woken up, and if the cover is opened, the system will be woken up.

In the embodiment of the present invention, when the notebook computer is in the sleep state, after the first signal for requesting to wake up the system monitored by the USB controller for the USB peripheral is not intercepted, the notebook computer is always kept in the original sleep state.

In the state of opening the cover, there is no need to intercept the wake-up behavior monitored at this time.

The wake-up interception module 440 further judges whether to wake up the system according to the cover state detection information:

If the lid state detection information carries a false value of the lid closing flag, it means that the notebook computer is currently in the open state, or the user’s intention to operate the notebook computer is to open the lid, then send a second signal to the power supply circuit to wake up the notebook computer. system.

FIG. 5 is one of the structural schematic diagrams of the integrated circuit provided by the present invention. On the basis of any of the above embodiments, as shown in Figure 5, the integrated circuit provided by the embodiment of the present invention includes a USB controller 510, an embedded controller 520, a power supply circuit 530, a first detection module 540 and a second detection module The module 550, the embedded controller 520 implements the above USB wake-up method when running.

The USB controller 510 is configured to send a first signal to the embedded controller when it is determined that the notebook computer is in a sleep state and monitors the touch operation of the USB peripheral.

The first detection module 540 is used to feed back the power supply status detection information carrying the set power supply logo to the the embedded controller.

The first detection module 540 is used to feed back the power supply state detection information carrying the set power supply logo to the the embedded controller.

The second detection module 550 is configured to feed back cover state detection information to the embedded controller based on the relative positional relationship between the screen surface and the keyboard surface of the notebook computer.

The power supply circuit 530 is configured to receive and respond to the second signal sent by the embedded controller, and perform corresponding power management on the working state of the notebook computer after it wakes up.

It should be noted that the second detection module 550 can be a Hall sensor composed of a voltage regulator, a Hall element, and a differential amplifier, and this type of sensor can output digital quantities. So that the conversion of the angle between the screen surface and the keyboard surface of the notebook computer is completely based on the digital circuit and has nothing to do with the analog circuit.

Specifically, the integrated circuit is composed of a USB controller 510 , an embedded controller 520 , a power supply circuit 530 , a first detection module 540 and a second detection module 550 . When the USB wake-up device arranged on the embedded controller 520 determines that the notebook computer has been in a sleep state according to the operating information of each part in the notebook computer, the power supply circuit 530 only activates the USB controller 510, the embedded controller 520, and the first detection module. The group 540 and the second detection module 550 are powered.

The first signal sent to the embedded controller 520 when the USB controller 510 monitors that the USB peripherals it manages is in an active state is used for the embedded controller 520 to determine whether to intercept this time according to the attribute of the first signal. Wake up to make the first judgment:

If the embedded controller 520 determines that the attribute corresponding to the first signal is not an application for waking up the system, it does not need to perform any operations and remains in the original sleep state.

If the embedded controller 520 determines that the attribute corresponding to the first signal is an application to wake up the system, it will inquire from the first detection module 540 whether the notebook computer is connected to a power adapter, and obtain the power supply feedback from the first detection module 540. State detection information for the embedded controller 520 to make a second judgment on the current usage scenario of the notebook computer according to the power supply state detection information:

If the embedded controller 620 determines that the power supply identification carried in the power supply status detection information indicates external power supply, it means that the usage scenario of the notebook computer tends to be that the user is charging the notebook computer. Once a wake-up event occurs, it is considered that the user needs to end the external charging in advance. It is necessary to be more tolerant of the wake-up actions monitored in this scenario. As long as the USB peripheral triggers a wake-up event, no matter whether the laptop is closed or not, the original sleep state will switch to the working state.

If the embedded controller 620 determines that the power supply identification carried in the power supply state detection information indicates that the internal battery is powered, it means that the notebook computer is currently powered only by the internal battery, and its use scenario tends to be carried by the user to carry the notebook computer and perform related operations. The wake-up action monitored in the scene is more vigilant. By querying the relative positional relationship between the screen surface and the keyboard surface of the notebook computer from the second detection module 550, and obtaining the cover state detection information fed back by the second detection module 550, For the embedded controller 520 to make a third judgment on whether to finally wake up the system according to the cover state detection information:

If the embedded controller 520 determines that the cover state detection information carries a cover-closed flag as a false value, which means that the notebook computer is currently in an open state, or the user intends to operate the notebook computer to open the cover, then it will send a message to the power supply circuit. The second signal to wake up the system.

The power supply circuit 530 receives and responds to the second signal, performs pulse modulation on the input power supply, realizes the functions of power supply conversion, automatic voltage stabilization and output adjustable voltage. Therefore, the notebook computer is switched from the power supply mode of the original sleep state to the power supply mode corresponding to the working state, so as to wake up the notebook computer.

If the embedded controller 520 determines that the cover state detection information carries a cover-closed flag as a true value, which means that the notebook computer is currently in the cover-closed state, or the user's operation intention on the notebook computer is to close the cover, then determine to intercept the current monitoring Peripheral wake-up operation, still maintain the original sleep state.

Among them, the power supply circuit 530 can be divided into two sub-circuits according to different control routes, one is a power supply circuit, which is dedicated to supplying power to different devices involved in different states. The other is the power-on circuit to trigger the power supply of all devices with one key in the power-on mode.

In the embodiment of the present invention, when the notebook computer is in a sleep state, after intercepting the first signal monitored by the USB controller to the USB peripheral for applying to wake up the system, the power supply state detection information fed back by the second detection module is first sent to the notebook computer.
