Description
Technical field
The invention belongs to the technical field of mainboard test, the diagnostic card of more particularly to a kind of testing host problem and diagnosis
Method.
Background technology
Conventional diagnostic card, as Display Technique, typically all shows two or multigroup two codes using charactron.
Maintenance personal must go to check corresponding explanation according to shown code, just know the event representated by the code that diagnostic card is shown
Barrier is explained.This user of service's scope that will result in diagnostic card is limited only to professional person, and layman sees frosty
Code is hung back, and is accomplished by asking for help when simple failure occurs in mainboard.This also causes diagnostic card to serve commonly
Popular the reason for.If frosty code can be translated into text importing to come out, and simple maintenance suggestion is enclosed, it is common to use
Family just can handle many failures by this diagnostic card, while can also improve the operating efficiency of maintenance personal.When code is interpreted into
Word and maintenance suggestion content it is relatively more, and LCD Panel size is limited, it is impossible to pass through the display of view picture screen completely
Out, this is also a difficult point part.
The content of the invention
It is an object of the present invention to provide a kind of diagnostic card and diagnostic method of testing host problem, the present invention can be by POST cards
Failure code is converted into corresponding literal interpretation and mobile cyclically in liquid crystal display screen display, practical, diagnostic result
It is easy-to-understand, improve operating efficiency.
To achieve these goals, the present invention uses following technical scheme：
A kind of diagnostic card of testing host problem, including：Micro-control unit, storage register, buffer register, logic electricity
Road unit and the first LCDs；The micro-control unit carries out two-way with storage register and buffer register respectively
Letter, the output end of micro-control unit is connected with the control of the first LCDs；The output end of the buffer register passes through logic
Circuit unit is connected with the control of the first LCDs.
Preferably, in addition to：Interface, the interface is used to access information of the isa bus in port.
Preferably, in addition to：Decoding circuit unit, the input of the decoding circuit unit is connected with interface, decoding
The output end of circuit unit is connected with the input of micro-control unit.
Preferably, in addition to：Second LCDs, the output end phase of second LCDs and micro-control unit
Connection.
Preferably, in addition to：3rd LCDs, the 3rd LCDs and the output end phase of storage register
Connection；
Control button, the control button is connected with the input of storage register.
The present invention also provides a kind of examining for the testing host problem that diagnostic card using above-mentioned testing host problem is realized
Disconnected method, comprises the following steps：
Micro-control unit receives POST card failure codes；
Micro-control unit calls text information corresponding with POST card failure codes in storage register；
Micro-control unit judges whether the capacity of text information is more than the maximum capacity of display of the first LCDs, if
It is that text information is temporarily stored in buffer register by micro-control unit, by logic circuit unit, makes text information
Movement is shown on one LCDs and iterative cycles are shown；If not, text information is directly displayed at the first liquid crystal display
On screen.
Preferably, while micro-control unit receives POST card failure codes, POST card failures code can be included the
On two LCDs.
Preferably, before micro-control unit receives POST card failure codes, in addition to：Interface accesses isa bus at end
The information of mouth.
Preferably, isa bus is accessed before the information of port in interface, in addition to：Select to store by control button
Basic input output system species and text information languages in register, and posted in the 3rd liquid crystal display screen display storage
The sequence number of the currently used basic input output system species of storage and text information languages.
Preferably, isa bus is accessed after the information of port in interface, in addition to：Decoding circuit unit sends out port
The information sent is converted into POST card failure codes, and POST card failure codes are sent to micro-control unit.
Compared with prior art, the present invention has advantages below：
1. diagnostic card has multiple interfaces, such as pci interface, PCIe interface, ISA interfaces, their work on the market at present
Principle is all to remove to access isa bus in the information of 80 ports by these interfaces, and basic input output system is during POST
16 carry system codes constantly can be sent to 80 ports, compile, shown finally by LED display screen through logic unit
Go out POST card failure codes.It is improved on basis herein of the invention, the basic of different vendor is write in storage register
The literal interpretation of different language corresponding to the POST card failure codes of input-output system and maintenance suggestion, so that by tradition
POST card failure codes translate directly into the languages of needs, such as Chinese, English, this purpose are able to be applicable different
The user of product and country variant, the scope of application is wider.
2. because of the limitation of diagnostic card size, cause to use larger LCDs, and a code institute
The word and maintenance suggestion number of words translated into compare many sometimes, to cause these words all to be shown on liquid crystal screen
Come, it is necessary to allow text subtile is from left to right mobile on screen to show, and can be shown with circulating repetition, user can be repeatedly thin
Reading, the present invention judges whether the capacity of text information is more than the maximum display appearance of the first LCDs by micro-control unit
Amount, if greater than the maximum capacity of display of the first LCDs, text information is temporarily stored in buffering and posted by micro-control unit
In storage, by logic circuit unit, making text information, movement is shown on the first LCDs and iterative cycles are shown；
If the maximum capacity of display of no more than the first LCDs, text information is directly displayed on the first LCDs.This
Invent the text information for POST card failure codes being converted into by buffer register and logic circuit unit in LCDs
Upper energy movement is shown and iterative cycles are shown, text information is preferably showed on LCDs.
3. the diagnostic card of the testing host problem of the present invention can be carried out on the electronic products such as Servers-all, computer
With applied widely.
4. the present invention disclosure satisfy that the use of the layman such as all research and development, test, production, client, user of service's model
Enclose and be not only limited to professional person, it is practical.
5. because diagnostic result is linguistic form known to user, diagnostic result is easy-to-understand, is easy to problem to solve as early as possible,
Operating efficiency is substantially increased, so that with good economic benefit.
