Having introduced the basic principles of the present application, the technical solutions of the present application will now be clearly and fully described with reference to the accompanying drawings, it being apparent that the embodiments described are only some, but not all, embodiments of the present application, and it is to be understood that the present application is not limited to the exemplary embodiments described herein. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application. It should be further noted that, for convenience of description, only some, but not all of the drawings related to the present application are shown.
Example 1
As shown in fig. 1, the present application provides a method for booting a computer by using a keyboard, wherein the method is applied to a USB port keyboard, and the USB port supports 3.3V voltage, and includes:
step S100: connecting a USB port of the USB port keyboard with a WOL (wake on network) signal port of a network card;
specifically, the USB port keyboard is any keyboard with a USB port that supports a 3.3V voltage. The WOL (wake on network) is a function supportable in the network card, preferably, the far-end wake-up command can be obtained by unpacking the data packet of the network, and the computer is powered on by communication between the network card and EC (Embedded Controller). The computer is started by means of EC through communication between USB port signals of the USB port keyboard and WOL signals of the network card.
The USB port of the USB port keyboard is connected with a WOL (wake on network) signal port of the network card, so that 3.3V voltage is supported for the USB port keyboard, a keyboard input signal is obtained, the WOL signal of the network card is triggered by the keyboard input signal, and a basic signal is provided for the subsequent computer startup.
Step S200: judging whether the current computer host is in a shutdown state or not;
further, as shown in fig. 2, the step S200 of the embodiment of the present application further includes:
step S210: and judging the current on-off state of the host computer through EC.
Further, after the step of determining whether the current host computer is in the shutdown state, step S200 of the embodiment of the present application further includes:
step S220: when the computer host is in a starting state, the WOL signal connection between the USB port and the network card is controlled to be closed through the EC.
Specifically, after the WOL signal of the network card is triggered, the network card is used to communicate with the EC, so that the host state of the computer is determined based on the EC. Preferably, the EC reports the information and methods to be reported to the operating system through the ACPI table of the BIOS and interacts with the operating system. When the computer is in a power-on state or a power-off state, the EC senses the state change of the computer through the port and triggers a signal, so that whether the computer is in the power-off state or not can be determined according to information contained in the signal.
Specifically, when the EC determines that the host computer is in the power-on state, it indicates that the host computer does not need to be powered on through the USB port keyboard at this time. Therefore, the connection of the WOL signal of the USB port and the network card is closed through EC control. For example, after the network card is woken up, the network card is always in a standby state no matter the computer is in a sleep state, a dormant state or a shutdown state, so that after the host computer is in a startup state, the connection between the USB port and the WOL signal of the network card is required to be closed. In one possible embodiment, if the USB port of the USB port keyboard port cannot wake up the WOL of the network card, the state of the network card may be detected to determine whether it is in the standby state. When the sudden power failure occurs, after the power supply is restored, the network card cannot be restored to the standby state on some equipment, and the network wake-up function cannot be completed at the moment.
Step S300: when the computer host is in a shutdown state, the WOL signal connection of the USB port and the network card is controlled by an EC (embedded controller);
specifically, when the EC (embedded controller) determines that the host computer is in a shutdown state, the EC controls the USB port of the USB port keyboard to be connected with the WOL signal of the network card, so that the input signal of the USB port keyboard is transmitted to the WOL signal of the network card, and the host computer is further awakened, thereby achieving the aim of starting up the computer. And a precondition is provided for the subsequent realization of the awakening of the computer host through signal connection.
Step S400: transmitting a trigger signal to the network card by using the USB port keyboard;
further, the step S400 of the embodiment of the present application further includes:
step S410: and sending the trigger signal through any key on the USB port keyboard.
Further, the step S400 of the embodiment of the present application further includes:
step S420: setting a starting trigger key;
step S430: and pressing the starting trigger button to send the trigger signal.
Further, the starting trigger key is any key or key combination.
Specifically, by pressing any key of the USB port keyboard, a trigger signal is obtained, and the trigger signal is transmitted to the network card through the USB port of the USB port keyboard, so that the transmission of the trigger signal is completed. The trigger signal is used for describing that a key in the USB port keyboard is pressed and transmitting a signal for waking up a computer. After the network card receives the trigger signal, the network card is in communication connection with the EC through the WOL signal in the network card, and then the wake-up of the computer is completed.
In one possible embodiment, the USB port keyboard may be divided into a main keypad area, a function keypad area, a control keypad area, and a number keypad area according to different functions of keys, each area having a plurality of keys. When a worker touches a key on the USB port keyboard by accident, the worker can acquire a trigger signal to start the computer. However, the staff does not need to use the computer at this time, so in order to avoid the computer being started when there is no startup plan, a startup trigger key can be set on the USB port keyboard, and when only the startup trigger key is pressed, the trigger information is acquired. By setting the starting trigger key, the false starting operation of the computer can be avoided.
Specifically, the start trigger key is a function key set on the USB port keyboard for controlling the start of the computer, and preferably, the start trigger key is any key or key combination. When the starting trigger button is pressed, the USB port keyboard obtains a trigger signal, and then is connected with the WOL signal of the network card through the USB port on the USB port keyboard, and further sends the trigger signal to the network card, and the network card is connected with the EC in a communication way to control the starting of the host computer. The start trigger key may be any key on the USB port keyboard, or may be a combination of multiple keys. If a single key can be set as a starting trigger key, optionally, the single key is an English character of the main keyboard area, including an A key, an F key, a G key, a K key, an L key and the like. The key combination can also be set as a start trigger key, and alternatively, the key combination can be a combination of English characters and keys in a functional key area, namely a combination of keys in different key areas, such as a combination of keys A and keys F1, a combination of keys F and keys F1, and a combination of keys K and keys ESC. The key combination can also be a combination of a plurality of keys in any key area, such as an A key and an F key combination, a Tab key and a Ctrl key combination, and an Alt key and a Ctrl key combination. Preferably, when the start trigger key is a key combination, the keys in the key combination can be pressed simultaneously, or the keys in the key combination can be pressed sequentially, so as to send the trigger signal. Therefore, the accuracy of computer startup can be improved by setting the startup trigger key.
Step S500: the network card generates a remote wake-up command by triggering a WOL signal, and the remote wake-up command is used for powering on and starting up a computer host through EC control.
Specifically, as shown in fig. 2, after the WOL signal of the network card obtains the trigger signal sent from the USB port of the USB port keyboard, the WOL signal is triggered to obtain the remote wake-up command, and then the computer host is powered on and started up through the EC (embedded controller). The remote wake-up command is a command for enabling the shutdown computer to enter a startup process, so that startup operation is completed. For example, when the host computer is stored in the cabinet and the power-on button of the computer cannot be pressed to complete the start-up of the computer, the operator controls the start-up of the computer by pressing a key (e.g., a K key) on a USB port keyboard connected to the computer. When the K key is pressed, a WOL signal of the computer card in a standby state is triggered through the USB port, and a remote wake-up command is generated through the WOL signal, so that the computer host is powered on and started.
In summary, the embodiment of the application has at least the following technical effects:
1. the method comprises the steps of connecting a USB port on a USB port keyboard with a WOL (wake on network) signal port of a network card, judging whether a computer host is in a shutdown state or not by using an EC (embedded controller), controlling the WOL signal connection of the USB port and the network card by using the EC (embedded controller) when the computer is in the shutdown state, and generating a remote wake-up command after the network card receives a trigger signal sent by the USB port of the USB port keyboard, so that the computer host is powered on and started by the EC (embedded controller). The technical problem that when the power button cannot be touched, the computer cannot be started up quickly and portably is solved, the control cost is reduced, and the technical effect that the computer is started up through the keyboard under the condition that a power interface is not required to be changed is achieved.
2. Under the condition that a specific chip is not needed, the technical effect of starting up the computer at low cost is realized based on the USB port keyboard.
3. By determining the on-off state of the host computer by using the EC, judging whether the computer is required to be started by using the USB port keyboard, the precondition confirmation of the computer starting by using the USB port keyboard is achieved, normal use of the keyboard is ensured, and the switching control of the keyboard function and the starting function is facilitated.
4. By setting the starting hot key, the starting hot key is optionally a certain key or a plurality of key combinations, so that the technical effect of avoiding the false starting caused by the false touch operation of the keyboard in the state of closing the computer is achieved.
