Abstract
The invention discloses a method and a system for remotely waking up a computer by using a USB, which can remotely wake up the computer in a 'sleep' state through a mobile phone terminal. The system comprises an MCU control module and a WiFi module. The system is led out a USB male connector and inserted into a USB female connector of a computer, and the system is identified as a type of 'HID keyboard equipment' by a computer operating system. The system supplies power for the MCU control module and the WiFi module after taking power from the USB. The WiFi module can transmit an instruction to the MCU control module after receiving a starting-up instruction, and the MCU control module simulates a computer keyboard by using an HID protocol and sends a space key signal to the USB. After receiving the space key signal, the computer is switched from the sleep state to the normal power-on state, thereby realizing the remote awakening of the computer.
Description
Technical Field
The invention relates to a method and a system for remotely waking up a computer by using a USB.
Background
In modern society life, computers are closely connected with life and work of people, and data materials, application running conditions and the like on the computers are often required to be checked in different places. But may cause the user not to remotely view or log in to use the computer because the computer is not used for a long time or the computer is in a sleep state due to hardware, software, network and other factors.
Because the computer is in a sleep state, the computer may be disconnected, and the method of using the remote control software to wake up and perform login management may be disabled.
Disclosure of Invention
The invention aims to provide a method and a system for remotely waking up a computer by using a USB, which can wake up the computer by remotely sending a wake-up command when the computer is in a 'sleep' state.
To achieve the above object, the remote wake-up provided by the present invention is achieved as such.
The WiFi module is connected with an external wireless router and is accessed to the Internet of things. The WiFi module I/O port is connected with the MCU control module, and when the WiFi module receives a 'start-up' command sent by the Internet of things, the command is sent to the MCU control module through the I/O port.
And after receiving the 'startup' command, the MCU control module sends a space key signal with an ASCII value of '00100000' to the USB by using the HID protocol. Thereby waking the computer "asleep".
Drawings
FIG. 1 is a block diagram of a remote wake-up computer using USB.
FIG. 2 is a flow chart of a method for remotely waking a computer using USB.
Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
A system for remotely waking up a computer by using a usb is shown in FIG. 1 and comprises an MCU control module and a WiFi module. MCU control module and wiFi module are got the electricity and are opened from the USB line, and at this moment the external router is connected to the wiFi module to link "thing networking", the user can use the cell-phone end to send the instruction through "thing networking". As shown in fig. 2, the WiFi module constantly detects whether the "internet of things" issues a "power on" instruction for the "internet of things". If the power-on command is detected, the WiFi module transmits the command to the MCU through the I/O port connected with the MCU. The MCU transmits a space key signal having an ASCII value of "00100000" using the HID command immediately after receiving the command. The computer will wake up after receiving the signal.
In specific implementation, as shown in fig. 1, the user clicks the "power on" button on the mobile phone. The "boot" information is sent to the internet of things. The WiFi module is connected with the Internet of things, can read the startup information, then forwards the command to the MCU control module, and sends a wakeup signal to the USB interface.
Claims (4)
1. A method and a system for remotely waking up a computer by using a USB are characterized by comprising an MCU control module and a WiFi module, wherein the system leads out a USB male plug and is inserted into a USB female plug of the computer, the system is identified as a type of HID keyboard equipment by a computer operating system, the system supplies power for the MCU control module and the WiFi module after taking power from the USB, the WiFi module is connected with an external router through the WiFi so as to be connected into the Internet of things, a user remotely sends a start-up command through the Internet of things, the WiFi module sends the command to the MCU control module after receiving the start-up command, the MCU control module simulates a computer keyboard by using an HID protocol and sends a space key signal to the USB, and the computer is converted from a sleep state to a normal start-up state after receiving the space key signal, so that the remote computer is wakened up.
2. A method for remotely waking up a computer system by using USB as claimed in claim 1, wherein the MCU module is recognized as "HID keyboard device" by the computer operating system after being connected to the computer by USB.
3. The system of claim 1, wherein the WiFi module receives a "power on" command through connecting to the internet of things, and after receiving the "power on" command, the MCU control module sends a "power on" command to the MCU control module, and after receiving the "power on" command from the WiFi module, the MCU control module sends a signal simulating pressing of a "space" key to the USB through an HID protocol.
4. A remote wake computer system using USB as claimed in claim 1 wherein the original state of the computer being woken up is a "sleep" state rather than a power off state.
