Computer power failure detecting instrument

Abstract

The invention discloses a computer power failure detecting instrument. The computer power failure detecting instrument comprises a single-chip microcomputer module, a voice module, an auxiliary power supply and a voltage comparator, wherein the auxiliary power supply supplies power for the modules; the voltage comparator is connected onto the power interface of a computer; the voltage comparator compares the voltage of the main board power interface with the voltage input by the auxiliary power supply, and outputs corresponding high-low electrical level; the single-chip microcomputer module is connected between the voice module and the voltage comparator, identifies the high-low electrical level output by the voltage comparator, identifies the failure point, and transfers a control signal to the voice module; the voice module identifies the control signal output by the single-chip microcomputer module, and broadcasts a corresponding failure language. Through the manner, the computer power failure detecting instrument can diagnose a computer power failure point, and is more accurate and intuitive when compared with conventional diagnosis methods.

Description

technical field [0001] The invention relates to the field of computer detectors, in particular to a computer power failure detector. Background technique [0002] With the popularization of computers, computer power failures occur frequently, causing countless cases of various losses to users. After a fault occurs, many people can judge some basic fault conditions by virtue of experience, but they cannot accurately judge the fault location. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a computer power failure detector, which can accurately determine the failure point of the computer power supply, optimize hardware coordination, eliminate it after detection, and improve the utilization rate of the power supply. [0004] In order to solve the above technical problems, a technical solution adopted by the present invention is: provide a computer power failure detector, comprising: a single-chip microcomp...
