The fault diagnosis card can simultaneously diagnose faults of the computer main board and the power supply unit, so that the use is convenient and the fault diagnosing time is saved.

Description

Diagnostic card

Technical field

The present invention relates to a kind of diagnostic card, relate in particular to a kind of diagnostic card that can diagnose computer main board and power supply unit fault simultaneously.

Background technology

Computer system is at startup self-detection (Power On Self Test; POST) in the process; BIOS (Basic Input Output System; Basic Input or Output System (BIOS)) can send 16 carry system codes, the POST information that different coded representation is different by 80 ports (fixed address port) on ISA (IndustryStandard Architecture, industrial standard architectures) bus.When BIOS carries out a certain test, at first this POST code is sent to this 80 port, if the next POST code of redispatching is accomplished in test smoothly.

Diagnostic card is a kind of test card that detects computer main board failure; Insert PCI (the Peripheral Component Interconnect of computer main board when diagnostic card; Peripheral component interconnect) or behind the ISA slot; Continuous access 80 ports, and demonstrate the POST code through the charactron of diagnostic card.When computer main board occurred wrong or crashes, the POST code that the charactron of this diagnostic card shows stopped to change.The tester judges the reason of makeing mistakes according to the POST code that stops to change that charactron showed.

Diagnostic card of the prior art can only be used for the fault diagnosis of computer main board, if the power supply unit of computer (Power Supply Unit, PSU) the caused by inconvenient judgment reason of specifically makeing mistakes that breaks down then.Therefore, there is certain limitation in diagnostic card of the prior art.

Summary of the invention

In view of this, be necessary to provide a kind of diagnostic card that can diagnose computer main board and power supply unit fault simultaneously.

A kind of diagnostic card that is used for diagnosing simultaneously computer main board and power supply unit fault, it comprises a control module, one first charactron, one second charactron, one first port and one second port; This first charactron, this second charactron, this first port and this second port are electrically connected with this control module respectively; This first port is electrically connected with a computer main board, and this second port is electrically connected with a power supply unit; This this first charactron of control module control shows the failure code of this computer main board, and this this second charactron of control module control shows the failure code of this power supply unit.

Compared to prior art, above-mentioned diagnostic card can be diagnosed the fault of computer main board and power supply unit simultaneously, and is easy to use, saves failure diagnosis time.

Embodiment

See also Fig. 1; Preferred embodiments of the present invention provides a kind of diagnostic card 100 that can diagnose computer main board and power supply unit fault simultaneously, and it comprises a control module 10, one first charactron 11, one second charactron 13, one first port one 5, one second port one 7 and one the 3rd port one 9.This first charactron 11, this second charactron 13, this first port one 5, this second port one 7 and the 3rd port one 9 are electrically connected with this control module 10 respectively.

This first port one 5 is electrically connected with a computer main board 30 to be measured.This second port one 7 is electrically connected with a power supply unit 50 to be measured.The 3rd port one 9 is electrically connected with a computer 70.This first charactron 11 is used to show the POST code of this computer main board 30.This second charactron 13 is used to show the feedback code of this power supply unit 50.The feedback code of this power supply unit 50 is provided by the production firm of power supply unit 50, and this feedback code burning is advanced in this control module 10 with storage.The POST code of this computer main board 30 can be referred to as failure code with the feedback code of this power supply unit 50.

Please combine to consult Fig. 2, the failure diagnostic process of this computer main board 30 and this power supply unit 50 is following:

Step S1: this computer main board 30 and these power supply unit 50 energisings, and this computer main board 30 is electrically connected and communicates with this diagnostic card 100 respectively with this power supply unit 50;

Step S2: these control module 10 controls make this first charactron 11 show the failure code of this computer main board 30, make this second charactron 13 show the failure code of this power supply unit 50;

Step S3: this control module 10 judges whether the failure code that this first charactron 11 and this second charactron 13 are shown stops to change; If do not stop the failure code to change, then execution in step S4; If have failure code to stop to change, then execution in step S5;

Step S4: this computer main board 30 continues operate as normal with this power supply unit 50;

Step S5: the failure code of failure code that this control module 10 will stop to change and 10 storages of this control module compares; And judge it is that computer main board 30 is made mistakes or power supply unit 50 is made mistakes, and this failure code that stops to change and judged result are sent to this computer 70;

Step S6: this computer 70 judges once more that according to this failure code that stops to change it still is that this power supply unit 50 is made mistakes that this computer main board 30 is made mistakes, and the reason that further affirmation specifically makes mistakes according to this failure code that stops to change.

Diagnostic card 100 of the present invention can be diagnosed the fault of computer main board and power supply unit simultaneously, and is easy to use, saves failure diagnosis time.

Be appreciated that the 3rd port one 9 and this computer 70 can omit, the reason that the tester also can make mistakes according to the failure code artificial judgment that stops to change that this first charactron 11 and this second charactron 13 are shown.
