Network remote wake-up method and system for computers

Abstract

The invention provides a network remote wake-up method and system for computers. The method comprises the following steps: S100, a relay logic control module is set on a wired network link of a computer, wherein the relay logic control module is used for realizing network wakeup in a standby power supply turn-off state; S200, when the computer is in a power-on state, the relay logic control module opens a wired network link to enable the network to be in a normal communication state; S300, when the computer is in a shutdown state, a sleep state, or a dormant state, the relay logic control module closes communication of the wired network link and is in a state of receiving a wake-up signal of a network end; when the wake-up signal is received, the relay logic control module enables the computer to enter a normal startup process. The system comprises the computer and the wired network link, the computer is connected with the wired network link, the wired network link is provided with the relay logic control module, and the relay logic control module is used for realizing network wakeup in a standby power supply turn-off state.

Description

technical field [0001] The invention relates to the technical field of computer energy saving, in particular to a computer network remote wake-up method and system. Background technique [0002] For industry mobile computers, home computers and industry computer systems, they generally have wired network functions. For industry computers, they generally have remote network wake-up functions. At present, they are basically implemented by sending wake-up signals through remote computers or devices in the shutdown state. This In the off state, the standby power must still be turned on when the target computer is turned off to realize the remote wake-up function. If there is no standby power, the remote device cannot wake up the target computer anyway. The power supply is a must-have condition, because having this condition will naturally increase the energy consumption of the computer or computer equipment in the off state, especially for mobile computer systems used in the ind...

[0002] For industry mobile computers, home computers and industry computer systems, they generally have wired network functions. For industry computers, they generally have remote network wake-up functions. At present, they are basically realized by sending wake-up signals through remote computers or devices in the shutdown state. This In the shutdown state, the standby power must still be turned on when the target computer is turned off to realize the remote wake-up function. If there is no standby power, the remote device cannot wake up the target computer anyway. The power supply is a must-have condition, because having this condition will naturally increase the energy consumption of the computer or computer equipment in the off state, especially for mobile computer systems used in the industry, which will virtually increase the energy consumption of the battery and make the battery life longer. Shorten, but also a waste of energy
