Abstract

The invention discloses a computer hard disk fault detector. The computer hard disk fault detector is connected to a power interface of a hard disk. The computer hard disk fault detector comprises a single-chip microcomputer processing module, a voice alarm module, an auxiliary power supply and a comparator module. The auxiliary power supply supplies power to each module. A divider resistor is connected between the in-phase ends of the auxiliary power supply and the comparator module. The power interface of the hard disk is connected with the reversed-phase end of the comparator module. The comparator module compares the voltage value input into the power interface of the hard disk and the voltage value input into the auxiliary power supply, and outputs corresponding high and low electric levels. The single-chip microcomputer processing module is connected between the voice alarm module and the comparator module. The single-chip microcomputer processing module identifies the high and low electric levels output by the comparator module to screen out fault points. In this way, the computer hard disk fault detector can combine load simulation with voice alarms, decrease the fault range, improve use efficiency and work efficiency and detect whether the hard disk in good or not accurately, visually and effectively.

Description

A kind of hard disc of computer fault locator

Technical field

The present invention relates to computer failure detection field, particularly relate to a kind of hard disc of computer fault locator.

Background technology

The effect that computing machine is brought into play in all trades and professions is increasing, in today it become we produce, life in requisite use instrument.But computing machine, in the situation that frequency of utilization is higher, often there will be some indescribable faults, these faults are difficult to judge by basic skills, and for example whether hard disk damages, and is perplexing maintenance job personnel always.

Summary of the invention

The technical matters that the present invention mainly solves is to provide a kind of hard disc of computer fault locator, the mode that can adopt fictitious load to combine with audio alert, dwindle fault coverage, improve service efficiency and work efficiency, can accurately, intuitively, effectively detect the quality of hard disk, find trouble spot.

For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of hard disc of computer fault locator is provided, be connected on hard disk power interface, described hard disc of computer fault locator comprises: single chip processing module, audio alert module, accessory power supply and comparator module; Described accessory power supply is given each module for power supply, between accessory power supply and the in-phase end of described comparator module, is connected to divider resistance; Described hard disk power interface is connected with the end of oppisite phase of described comparator module; Described comparator module compares the magnitude of voltage of described hard disk power interface and accessory power supply input, and exports corresponding low and high level; Described single chip processing module is connected between audio alert module and comparator module, and described single chip processing module is identified the low and high level of described comparator module output, screens out trouble spot, and control signal is passed to audio alert module; The control signal identification that described audio alert module is sent described single chip processing module, and play voice.

Preferably, described audio alert module stores fault alarm sound, and described audio alert module, to the signal screening from one-chip computer module, is sent corresponding line fault voice.

The invention has the beneficial effects as follows: the present invention can judge hard disc of computer trouble spot, more accurate in traditional diagnosis method, directly perceived.

Brief description of the drawings

Fig. 2 be shown in a kind of comparator module conspectus of hard disc of computer fault locator;

Fig. 3 be shown in a kind of single chip processing module and audio alert module conspectus of hard disc of computer fault locator;

In accompanying drawing, the mark of each parts is as follows: 1, hard disk power interface; 2, comparator module; 3, single chip processing module; 4, audio alert module.

Embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.

Refer to Fig. 1 to Fig. 3, the embodiment of the present invention comprises:

A kind of hard disc of computer fault locator, is connected on hard disk power interface 1, and described hard disc of computer fault locator comprises: single chip processing module 3, audio alert module 4, accessory power supply and comparator module 2; Described accessory power supply is given each module for power supply, between accessory power supply and the in-phase end of described comparator module 2, is connected to divider resistance; Described hard disk power interface 1 is connected with the end of oppisite phase of described comparator module 2; Described comparator module 2 compares the magnitude of voltage of described hard disk power interface 1 and accessory power supply input, and exports corresponding low and high level; Described single chip processing module 3 is connected between audio alert module 4 and comparator module 2, the low and high level that described single chip processing module 3 is exported described comparator module 2 is identified, screen out trouble spot, and control signal is passed to audio alert module 4; Described audio alert module 4 stores fault alarm sound, and described audio alert module 4, to the signal screening from one-chip computer module, is sent corresponding line fault voice.

When detection failure, hard disk is received on 4 core mouths of detector for electrical outlet, by the circuit access detector of power supply, connected 5V accessory power supply, now, detector is started working.Hard disk power interface 1 needs two kinds of voltage (+5V of input, + 12V) the access detector interface corresponding with it respectively, the lead-in wire p1-p2 of interface connection corresponding to the lead-in wire p1-p2 of LM339 voltage comparator, the pin p01-p02 of voltage comparator is connected to the pin p01-p02 of 89c51 type single-chip microcomputer; Described voltage comparator compares the magnitude of voltage of input, exports corresponding low and high level, and when level is input to after single chip processing module 3, single-chip microcomputer is processed and calculated level signal, finds out trouble spot, and signal is passed to audio alert module 4; The pin K1 of the PM66S speech chip in audio alert module 4, pin P20, the P21 that K2 is connected to single-chip microcomputer, pin int0 and the int1 of int0 and int1 access single-chip microcomputer; Audio alert module 4 receives after control signal, identifies, and plays corresponding failure voice, thereby learns faulty line.The mode that the present invention can take fictitious load to combine with audio alert, can intuitively, effectively judge the quality of mainboard, checks out corresponding trouble spot.

The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes instructions of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
