Abstract

The invention provides a method for diagnosing a board card fault. Fault diagnosis of a PCI bus module is completed through software, the fault can be positioned on a main logic chip, the method is especially suitable for a CPCI computer board card which is high in integration degree and whose case is not easy to detach, and the method can assist maintenance staff in rapidly and accurately detecting hardware fault equipment. A system comprises a bottom layer fault diagnosis code module, a fault diagnosis middle element module and a fault diagnosis application program module, wherein the fault diagnosis code module is used for register access and main chip function detection; the fault diagnosis middle element module is used for finishing scanning PCI bus equipment, reading configuration files on the corresponding bus equipment, skipping to an entry function of a designated fault diagnosis code, and carrying out fault diagnosis detection, and users do not need to modify the part; in terms of the fault diagnosis application program module, the users can call the bottom layer fault diagnosis code module to obtain state information of the board card through the fault diagnosis middle element module, and then console programs or interface application programs are written through the fault diagnosis application program module according to needs.

Description

A kind of method of diagnosing board fault

Technical field

The present invention relates to field of computer technology, specifically a kind of method of diagnosing board fault.

Background technology

Development along with information society arrival and computer technology, the processing power of computing machine significantly improves, the bussing technique adapting with it also obtains tremendous development, the computer bus of some high handling capacities is come out one after another, pci bus be one of them representative, and can meet rugged surroundings and high reliability pci bus---cpci bus is widely applied at industrial control field and military industry field.Hot-swappable, high open, high reliability that CPCI has, some novel naval equipments have been used cpci bus ruggedized computer and board in a large number.

Higher due to the digitizing of CPCI computer card, integrated degree, it is carried out to fault detection and diagnosis and become very difficult.Especially more at system board, when dismantling board in airtight situation and comparatively bothering, apply a kind of maintenance personal of being convenient to and use, can help the method for the accurate detection hardware equipment failure of maintenance personal very necessary.

Summary of the invention

The object of this invention is to provide a kind of method of diagnosing board fault.

The object of the invention is to realize in the following manner, by software, complete the fault diagnosis of pci bus module, localization of fault is arrived to main logic chip, be particularly useful for integrated degree higher, the airtight not easily detachable CPCI computer card of cabinet, can help quick and precisely detection hardware faulty equipment of maintenance personal, system comprises bottom DTC module, fault diagnosis middleware module and diagnosis application program module, wherein:

DTC module, relevant to bottom, comprise register access, master chip Function detection, the entrance function parameter of appointment in configuration file must with require consistent;

Fault diagnosis middleware module, this module completes the scanning of pci bus equipment, the entrance function of the DTC that reads and jump to appointment of the configuration file on respective bus equipment, carries out fault diagnosis and detects, and these certain customers do not need to make an amendment again;

Diagnosis application program module, user calls by fault diagnosis middleware module the status information that bottom DTC module gets board, then by diagnosis application program module, writes as required Console program or interface application.

The invention has the beneficial effects as follows: this programme completes the fault diagnosis of pci bus module by software, can be by localization of fault to main logic chip.Be particularly useful for integrated degree higher, the airtight not easily detachable CPCI computer card of cabinet, can help quick and precisely detection hardware faulty equipment of maintenance personal.

Use this method for diagnosing faults to detect in detail the computer card of pci bus, can be by localization of fault to main logic chip.This board method for diagnosing faults software is realized and is comprised bottom DTC, fault diagnosis middleware and three modules of diagnosis application program, is described in detail as follows:

DTC is relevant to bottom, comprises register access, master chip Function detection etc., and concrete methods of realizing is relevant to corresponding board.The entrance function parameter of appointment in configuration file must with require consistent.

Fault diagnosis middleware has acted on the characteristic of middleware, shield the complicacy of underlying operating system, make upper level applications developer in the face of a simple and unified development environment, reduce complicacy and technical burden in program design, and then can improve development efficiency.This module completes the scanning of pci bus equipment, the entrance function of the DTC that reads and jump to appointment of the configuration file on respective bus equipment, carries out fault diagnosis and detects.These certain customers do not need to make an amendment again.

Diagnosis application program is that user calls by fault diagnosis middleware the implementation procedure that bottom DTC gets the status information of board.User writes Console program or interface application as required.

Accompanying drawing explanation

Fig. 1 is diagnostic flow chart.

Embodiment

With reference to Figure of description, method of the present invention is described in detail below.

Diagnose a method for board fault, this method is verified on network board (its chip of network control is 82546 and 82573) and serial port board, the Console program pattern that diagnosis application program adopts.

If use other boards, fault diagnosis middleware module does not need to make an amendment, and diagnosis application program reusable (if there is interface demand, needing to write interface application) only need be write bottom DTC and respective profiles.Concrete steps are as follows:

Trading company of factory and device number are distinguished as 8086 and 1079 network controller 82546 board configuration filenames and are called 80861079.bit, and file content is as follows:

#BEGIN

PRONAME=bis-redundant network card failure diagnosis installation files

VENDORID?=?0x8086

DEVICEID?=?0x1079

OS?=?vxworks

DEVNAME?=?geidr

FORMAT?=?ELF

VERSION?=?1.0

DEVDESC?=?Dual?Net

VENDORNAME?=?lccy

FILENAME?=?DIAG_Nnet.out

BITFUNC?=?GENTFdtDll

#END

Filename DIAG_Nnet.out is the DTC program that network board is corresponding, the entrance function that GENTFdtDll is DTC.

Function declaration is as follows:

int?GENTFdtDll(int?No,PDEVINFO?pDevInfo);

Wherein, PDEVINFO is defined as follows:

typedef?struct{

char?devState;

char?devInfo[256];

}DEVINFO,*PDEVINFO;

User need carry out assignment to each member's value in GENTFdtDll, member devState designation equipment state (0-equipment is normal, 1-unit exception) wherein, and member devInfo describes the status information of equipment.

Except the technical characterictic described in instructions, be the known technology of those skilled in the art.
