Computer power outage and power failure protective system

Abstract

The invention discloses a computer power outage and power failure protective system. The system comprises a power supply enabled circuit and a mainboard CPU core voltage acquisition program, and the power supply enabled circuit comprises a power supply storage circuit, a voltage stabilizing circuit, a voltage boosting circuit and a computer power voltage detection judging circuit; the computer mainboard power failure protective system detects that a computer is suddenly in outage and conducts power-off, and a detection circuit detects the change of the computer voltage; when the voltage value reaches a certain threshold value, the power supply enabled circuit of an emergency power supply is switched, voltage stabilization of the power supply is conducted, and a computer program acquires core voltage data of a mainboard CPU in real time; when the data reaches a preset threshold value, the system controls the computer automatically and conducts power-off, and the protective effect for computer mainboard hardware is achieved.

Description

technical field [0001] The invention relates to a protection system, in particular to a power failure and power failure protection system for a computer. Background technique [0002] Computers have become irreplaceable and important electrical appliances in modern society. However, due to the instability of computer power supply voltage or sudden power outage time, the computer loses power supply, which will cause loss of hardware on the computer motherboard. Seriously, it will cause hardware damage and data loss, so it is very necessary to invent a computer power failure and power failure protection system to judge in time when the computer power failure or power failure, and to perform protection shutdown. Contents of the invention [0003] The object of the present invention is to solve the above problems, and provides a multimedia classroom anti-theft system. [0004] The purpose of the present invention is achieved in the following ways: [0005] A computer power s...
