Computer system AC power supply control device using host computer power supply switch and battery

Abstract

The invention relates to an AC power source controlling device of a computer system by using a power source switch of a host computer and a cell. After the host computer of a desktop computer is turned off, the AC power source of the computer system is automatically turned off. The defects of inconvenient use, long-term poor safety, effects on the original appearance of the host computer, and wrong order of external turning on and turning off the host computer in the current controlling device is overcomed. The power source switch of the host computer provides a triggering signal for the controlling device which recovers the normal operation of the power source switch of the host computer after the host computer is turned on; the cell provides electric power for the controlling device in a long-time. When the computer system is in a state of complete interruption of power supply, the controlling device is triggered by the power source switch of the host computer to connect the AC power source of the computer system for providing power supply externally and delaying the starting of the host computer; the normal operation of the power source switch of the host computer is recovered after the host computer is turned on; after the host computer is turned off, the AC power source of the computer system is automatically cut off in a delay manner, and the power supply of the system is completely cut off. The device is the AC power source controlling device of common computer systems, thus being applicable to the current common mainstream desktop computers.

Description

Technical field [0001] The invention relates to a control device for automatically shutting off the AC power supply of a computer system after the mainframe of a desktop computer is shut down. Background technique [0002] At present, computer systems have been widely used in all aspects of social life. After the computer system is shut down, for the purpose of saving energy, preventing electrical fires and prolonging the life of equipment, various existing AC power control devices for desktop computer systems have been produced. It can automatically shut off the AC power supply of the computer peripherals after the host computer is shut down. While the existing AC power supply control devices for various desktop computer systems produce positive social effects, they also have some defects more or less: the use of new operation methods changes the normal operation of the operator when starting, shutting down and using the computer. Inconvenient use due to usage habits; the ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the disadvantages of wasting energy caused by not turning off the AC power supply after the desktop computer system is shut down, easily causing electrical fires, shortening the service life of equipment, etc., and mainly to eliminate the above-mentioned various defects of the existing desktop computer system AC power control device, The invention provides an AC power control device suitable for common desktop computer systems. The device is easy to use, has strong safety, does not affect the original appearance of the computer host, and follows the principle of turning on the peripherals first and then turning on the computer system when switching on and off the computer. The principle of host, turn off the host first, and then turn off the peripherals
