Computer remote wakeup method and device based on network

Abstract

The invention discloses a computer remote arousal method and device based on network, which comprises the following steps: the computer network interface card supports remote arousal function; the pulse sending unit is connected between network interface card and computer mainboard power; the starting signal output end of network interface card LAN connects signal input end of pulse sending unit, whose output end connects pulse switch of computer mainboard power; (1) the computer network interface card judges whether the computer lies in the starting condition after it receives arousal signal of computer control in the LAN; if yes, the process is over; if not, the process enters step (2); (2) the network interface card sends LAN starting signal to trigger pulse sending unit to generate pulse control signal, which triggers pulse switch of computer mainboard power to open computer.

Description

technical field [0001] The invention relates to a method and device for remotely waking up a computer based on a network. Background technique [0002] The development of economy and society requires communication and resource sharing among users, and it is necessary to connect a group of computers into a network. In the computer network, in order to solve the problem of lack of IP addresses and the needs of information sharing, the local area network is the most widely used one. It uses the broadcast method to send broadcast packets to the clients in the same local area network, which greatly facilitates the interaction of information. Such as figure 1 As shown, in the existing typical local area network, the computers included are: the network master control terminal computer 110, and a plurality of controlled terminal computers such as 120, 121, 122, ... 12n, etc., these computers are shown in Fig. Connect to a local area network in a Chinese way. In real life, the app...

Problems solved by technology

[0004] However, this existing remote booting method has many defects, so that the wake-up function of the computer cannot be realized in many cases.

First of all, the premise of realizing the above booting method is that the chipset 221 must support the power management protocol, and the computer-related equipment must support the setting of the network card wake-up function (for example: the BIOS must support the wakeupon LAN function). Without the support of these conditions, the network wake-up cannot be realized. function to wake up the computer; secondly, when the power supply of the computer system is completely disconnected (no power supply at all), although the network card 210 can receive the network wake-up command and send the power management signal PME#, but due to the computer wake-up control related devices ( For example: the original settings of the computer chipset 221, some related computer equipment) are lost so that the function of waking up the computer is invalid
