Abstract

The utility model provides a diagnostic card, which comprises a computer bus interface, a diagnostic module, a self-checking module, a first display unit, and a second display unit, wherein the diagnostic module and the self-checking module are respectively connected with the computer bus interface; the diagnostic module and the self-checking module are mutually connected; the first display unit is connected with the diagnostic module; and the self-checking module is connected with the second display unit. The diagnostic card has the beneficial effects that: as the diagnostic module is connected with the computer bus interface, the diagnostic module and the self-checking module are mutually connected; when the second display unit displays codes, the first display unit can display corresponding characters like start codes, fault codes or ok codes; therefore, users can distinguish; moreover, the diagnostic card is more beneficial to detecting computer faults.

Description

Diagnostic card

Technical field

The utility model relates to a kind of detection of electrons product, relates in particular to a kind of diagnostic card.

Background technology

When code of traditional diagnostic card demonstration, whether you must see it clearly and be stopped to this code by a series of other code change. if this sign indicating number is a failure code so; If not, this code is once the demonstration of starting shooting, this sign indicating number be initial code so, and is meaningless. because the speed of computer reveal codes is very fast, human eye can't find out it whether by other code change to this code, can only be used as the failure code processing to it at this moment.If can not fix a breakdown, then be likely initial code.

We call initial code to the code that diagnostic card shows for the first time. because computer glitch diagnostic card itself also is a kind of electronic equipment. after it powers up, it can show that automatically a code comes out. and this code is not the shown code of computer BIOS self check, so code is meaningless, if user's mistake is thought failure code with initial code, can mislead the user and disorderly repair and the expansion fault.

The global computer mainboard is multifarious, and brings in constant renewal in, and the indicated fault of therefore same code value can be different fully, and current diagnostic card exists:

1, any diagnostic card research and development manufacturer neither could define and also could obtain complete BIOS ERR implication comprehensively in real time!

2, the code implication contains much information, if utilize computer to search code implication information, in the time of many (there is fault in tested computer) do not have second computer to use; If all code implication information are printed as instructions, have so much of a reading room, therefore want to consult the code implication and seemingly look for a needle in a haystack!

3, the mainboard BIOS fault self-checking program that has is the code that the fault self check can be passed through at last to the diagnostic card conveying, rather than failure code!

4, the current shown code of diagnostic card is that " failure code " or " OK sign indicating number " (code that does not have fault) or " initial code " are difficult to judge on earth.

The utility model content

In order to solve the problems of the prior art, the utility model provides a kind of diagnostic card.

The utility model provides a kind of diagnostic card, comprise computer bus interface, diagnostic module, selftest module, first display unit, second display unit, described diagnostic module links to each other with described computer bus interface respectively with described selftest module, described diagnostic module and described selftest module interconnect, described first display unit links to each other with described diagnostic module, and described selftest module links to each other with described second display unit.

As further improvement of the utility model, described selftest module comprises that the BIOS ERR monitors that analytic unit and coupled BIOS ERR receive the buffer memory assembly, and described BIOS ERR monitors that analytic unit links to each other with described diagnostic module.

As further improvement of the utility model, be connected with the interface communication controller between described computer bus interface and the described diagnostic module.

As further improvement of the utility model, the multimedia that singly is connected with of described diagnostic module and described first display unit is exported driven unit.

As further improvement of the utility model, described diagnostic module comprises single-chip microcomputer, and described single-chip microcomputer shows that with described first monolithic links to each other with described computer bus interface respectively.

As further improvement of the utility model, described second display unit also comprises source code display unit and corresponding code display unit, and described source code display unit all links to each other with described computer bus interface with described corresponding code display unit.

The beneficial effects of the utility model are: because diagnostic module links to each other with described computer bus interface, described diagnostic module and described selftest module interconnect, so when the second display unit reveal codes, described first display unit will show corresponding literal, as initial code, failure code or ok sign indicating number, thereby the user can be distinguished, more help the detection of computer glitch.
