CN101464499A - Design method for computer power supply with acousto-optic alarm function - Google Patents

Abstract

The invention provides a design method of a computer power supply with an audible and visual alarm. The method comprises the following steps: supplying electric energy for a detecting module through a button battery, detecting the each-path output of the computer power supply trough a detecting module, and prompting a defective output line through light and sound. The power supply comprises a power supply module (1), the detecting module (2) and an alarm module (3). Compared with the prior art, the design method has the advantages that the failure or the abnormity of the power supply can be diagnosed without a special measuring tool, thereby resulting in convenience and being favor of immediately discovering and properly solving problems, so that the method has the advantages of wide development prospect and application value.

Description

A kind of method for designing with computer power supply of sound and light alarm

Technical field

The present invention relates to the computer power supply field, a kind of single supply method that can realize light and audible alarm specifically is provided.

Background technology

Traditional single supply if take place to exceed standard such as 3.3V unusually, because of the supvr can't find to produce hidden danger, thereby jeopardizes the safe operation of system without any fault or unusual deixis in its operational process.In when maintenance, unless by multimeter even more professional instrument, otherwise can not be accurately and even judge the fault of power supply roughly.If can increase fault or unusual deixis in single supply, be to use light or sound commonly used reach, and just can bring into play effect in above-mentioned occasion, accelerate the solution of problem, avoid hidden danger, and systematically safe operation is provided simultaneously.

Summary of the invention

A kind of single supply method that can realize light and audible alarm utilizes sound and light to judge whether single supply is normal.The ultimate principle of this method is the detection module that uses the button cell power supply by, and whether detect each group output normal, and points out by light or sound.This method comprises three unit: power module (1), and detection module (2), alarm module (3), the abbreviated functional description of each module is as follows:

(1) power module: i.e. ordinary single power supply, finish the AC/DC conversion.

(2) detection module: by button cell power supply, be responsible for detection+3.3V ,+5V ,+12V ,-12V ,+whether 5VSB and PG signal unusual;

(3) alarm module: comprise light emitting diode and hummer, realize light warning and sound warning function respectively.

The invention has the beneficial effects as follows: need not promptly can diagnose power fail or unusual, very convenient by the special measurement instrument, also help in time pinpointing the problems and properly settling, thereby make this method have boundless development prospect and using value.

1, description of drawings

Accompanying drawing 1 can be realized the power principle figure that sound and light are reported to the police;

2, embodiment

With reference to accompanying drawing method of the present invention is done following detailed description the in detail

The invention provides a kind of method for designing with computer power supply of sound and light alarm, this method is to provide electric energy by button cell for detection module, by each the road output of the dynamo-electric source of detection module detection computations, point out the outlet line that breaks down by acousto-optic, power supply comprises power module (1), detection module (2), and alarm module (3) is wherein:

(1) power module: i.e. ordinary single power supply, finish the AC/DC conversion;

(2) detection module: by button cell power supply, be responsible for detection+3.3V ,+5V ,+12V ,-12V ,+working condition of 5VSB and PG signal;

(3) alarm module: comprise light emitting diode D and hummer Y, realize light warning and sound warning function respectively.

Embodiment

Employed power module (1) detection module (2) and alarm module (3) are known commercially available prod in the power supply, detection module is mainly used in voltage, the electric current that detects each road output of power supply, in case it is unusual that certain road output occurs, detection module triggers alarm module and sends sound and light alarm or trigger the computer shutdown program.

Claims (1)

1. method for designing with computer power supply of sound and light alarm, it is characterized in that, provide electric energy by button cell for detection module, by each the road output of the dynamo-electric source of detection module detection computations, point out the outlet line that breaks down by acousto-optic, power supply comprises power module (1), detection module (2), alarm module (3) wherein:

(1) power module: i.e. ordinary single power supply, finish the AC/DC conversion;

(2) detection module: by button cell power supply, be responsible for detection+3.3V ,+5V ,+12V ,-12V ,+working condition of 5VSB and PG signal;
