Intelligent computer power supply integration system

Abstract

The invention relates to a power integration system of an intelligentized computer and comprises a working power supply circuit, a battery power supply circuit and a power-down signal monitoring circuit. The power-down signal monitoring circuit is used for monitoring whether the electricity is cut off, and generates two power-down pulse signals when the electricity is suddenly cut off, one signal is used for starting the battery power supply circuit to provide a working power supply for the computer, so as to supply enough power to the mainboard to start the sleep and shutdown functions, while the other signal is directly sent to a power switch of the mainboard of the computer to start the preset sleep and shutdown functions attached by the computer, thus achieving the goal of storing data and resetting the next start. Therefore, the system can start the preset sleep and shutdown functions attached by the computer by the pulse signal generated by the power-down signal monitoring circuit, no software needs to be installed, neither communication interface nor related circuit model needs to be arranged, thus the structure is simpler and complicated installation is avoided; besides, the performance is stabler, the cost is low and the operation is convenient.

Description

technical field [0001] The present invention relates to the field of computer power supplies, in particular to a computer sleep function that can be activated when the city power is suddenly cut off, and can automatically save all the data currently operated by the user, and at the same time reset to the state before the power failure after the next startup. Integrated computer power supply system. Background technique [0002] The computer power supply usually uses an external AC power supply (AC power supply) to filter out various interference signals through an EMI filter circuit, and then converts the AC power supply into a smooth DC power supply (DC power supply) through rectification and filtering to provide power for the computer. When the traditional computer power supply is suddenly interrupted by the mains power supply, the data of the running computer will often be lost, and the running data will be lost in the blink of an eye after the intense work of the user, w...

Problems solved by technology

However, because the system uses a communication interface circuit and a power-off processing module to process communication signal instructions, it must install specific program software to activate the computer sleep function by performing a large number of calculations and judgments inside the program software. The cost of development is high, and the installation is cumbersome, which is not conducive to marketing
