Computer power supply fault detection system

Abstract

The invention relates to a computer power supply fault detection system, relates to the field of computer power supply fault detection, and can detect computer power supply faults and take a power-off measure in time. The computer power supply fault detection system comprises a voltage acquisition circuit, an A / D converting circuit, a control circuit and a circuit breaker. The voltage acquisition signal output end of the voltage acquisition circuit is connected with the voltage acquisition signal input end of the A / D converting circuit; the voltage acquisition signal output end of the A / D converting circuit is connected with the voltage acquisition signal input end of the control circuit; and the control signal output end of the control circuit is connected with the control signal input end of the circuit breaker. By detecting voltage parameters under the computer power supply operating state, whether a computer is in a normal operating state is judged; and once the computer is in an abnormal operating state, the circuit breaker is controlled to carry out power-off operation immediately.

Description

technical field [0001] The invention relates to the field of computer power failure detection. 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 that can detect power failures, but most of them are only limited to detecting power failures, and subsequent power-off measures need to be operated manually. Also equivalent t...
