Abstract
The utility model relates to a PC hardware failure detecting card, consisting of five programmable logic controllers, two pieces of 74 serial digital chips, two LED digital code pipes, a periphery resistance capacitance element and a circuit board; wherein, the card is inserted into an ISA groove of a PC or a PCI inserting opening of the PC. With the form of hexadecimal system digital code, PC hardware failure positions are displayed; therefore, the maintenance person knows clearly the failure of the PC hardware.
Description
The utility model relates to a kind of maintenance tool, particularly a kind of PC hardware failure detection card.
As everyone knows, PC is high-tech product, and it mainly is made up of the hardware and software two large divisions.And hardware be by and complicated electronic circuit constitute each unit or parts, as mainboard, CPU, hard disk, CD-ROM drive, floppy drive.Wherein any one partly breaks down, and all can have influence on normal operation and the use of PC.
At present, inspection PC hardware fault mainly leans on the maintenance personal according to phenomenon of the failure, and the contingent position of fault analysis and judgement makes maintenance job have sizable difficulty by rule of thumb.
Comprehensive above-mentioned the utility model, its objective is provides a kind of PC hardware failure detection card.It can demonstrate PC hardware fault position with the hexadecimal digit code form, and the maintenance personal is come into plain view to the fault that PC hardware takes place, and having overcome in the past fully by rule of thumb, failure judgement causes mistaken diagnosis.
The purpose of this utility model is achieved in that on the circuit board of a band PC mainboard expansion slot socket and is equipped with A1, A2, A3, A4, A5, A6, A7 integrated circuit (IC) chip, two 7 sections LED charactrons, and peripheral Resistor-Capacitor Unit.A1, A3 are power supplies and control concrete output current according to the code of A2, A4, A2, A4 are the main code working procedures of ISA socket, and A5 is No. 1 code output of PCI, and A6 is No. 2 code outputs of PCI, A7 is a PCI socket power supply controlling and driving, and double figures sign indicating number pipe LED shows failure code.Thereby realize indication fault purpose partly.
Below, in conjunction with the accompanying drawings to the utility model PC hardware failure detection card, do further to describe.
Accompanying drawing is the circuit theory diagrams of the utility model embodiment.
Among the figure: A1 is 74F138,3,8 code translators, A3 is the 74F374 data latches, A2, A4, A5, A6, A7 is the 16V8 programmable logic controller (PLC), the signal that PC inserts into from the ISA socket, through A174F138,3,8, code translator carries out fixed address decoding and locks, through 15 pin output control, whether the beginning contravention of A2 programmable logic controller (PLC) whether the LED charactron is lighted and controlled thereby controlled A2, and A3 is the 74F374 data latches, the digital coding that PC sends here is latched, and data are sent into the A2 driving decipher, by 2 charactrons of A2 driving LED code being shown, PC is at normal charactron data presented code in service, because flash across, naked eyes be can't see, and operation stops when having only PC to break down, and code just shows and latchs, thereby judge that according to code the trouble location of PC, specific code represent that what fault searches in the product description correspondence.
PCI socket control principle is similar with ISA, and just this demonstration has used 3 can compile the logic controller chip, is not repeated.Light when LED normally moves in system among the figure.
