Operation maintenance system of computer power supply

Abstract

The invention relates to an operation maintenance system of a computer power supply, and relates to the field of the operation maintenance of the computer power supply. The operation maintenance system can detect the faults of the computer power supply and maintain the normal working state of the computer. The operation maintenance system of the computer power supply comprises a voltage collection circuit, an A / D conversion circuit, a control circuit, a switching circuit and a standby power supply, wherein the voltage collection signal output end of the voltage collection circuit is connected with the voltage collection signal input end of the A / D conversion circuit; the voltage collection signal output end of the A / D conversion circuit is connected with the voltage collection signal input end of the control circuit; the control signal output end of the control circuit is connected with the control signal output end of the switching circuit; and the power supply signal input / output end of the switching circuit is connected with the power supply signal output / input end of the standby power supply. The operation maintenance system is suitable for carrying out fault detection on the computer power supply and maintaining the normal operation of the computer power supply.

Description

technical field [0001] The invention relates to the field of computer power supply operation and maintenance. Background technique [0002] Computers have become an indispensable tool in people's daily life. Whether it is to obtain news information or conduct scientific research and creation, in many cases it needs to rely on computers to achieve. In the process of people's daily use of computers, power failures often occur. When the power consumption is too large, the output power of the power supply cannot meet the required voltage power, and a short circuit and open circuit will occur. It is too late to take measures when the above situation occurs. Therefore, a computer power failure detection process is needed, which can predict power failure in advance. [0003] At present, there are many systems and methods capable of detecting power failures, but most of them often take the action of directly cutting off the power after detecting a power failure. It will cause loss...
