Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an information processing apparatus, and more particularly to an information processing reconfiguration that includes a plurality of modules and a diagnostic processing section that identifies 14 faulty locations within a failed module.

(Prior Art) Conventionally, in this type of information processing device, when a failure occurs, a diagnostic processing unit analyzes the failure information and points out the failed module and the faulty V8 location within the module.

The maintenance name reads the information from the display device or printing device,
A faulty module was replaced. Also, of the faulty module! ! As immediate information, attach the information that points out the faulty +a location in the module from the printing device or the information that was output to the magnetic media failure etc. to the faulty module and attach it to the faulty module.
! ! ! It was sent to the department. The repair department receives this and
The information was retrieved from the output list or output medium and used to repair the failed module.

[Problem to be solved by the invention]

Conventional information mentioned above! LA management equipment must send information pointing out the failure location in a failed module together with the module on a list or magnetic medium, so the list or medium may be lost due to human error, and In some cases, it may be impossible to take out the media for security reasons, or inspection and approval may be required to take out the output list, which has the disadvantage that failure information may not be retrieved.

An object of the present invention is to provide information processing 8 that does not cause failure point pointing information to be lost due to human error, and that does not require approval from the user for pointing out a list of failure point pointing information, media, etc. It is to make a contribution to the place.

[Means to solve the problem]

In the information processing device of the present invention, each module has a fault location identification information storage section made of writable and erasable non-volatile memory, and the diagnostic processing section is configured to
The present invention is characterized in that information pointing out point IIa is stored in a failure point pointing information storage section of the failure module.

(For use in Brazil) Since the failure point pointing information storage unit is provided in the module which is the unit of failure replacement, the failure point pointing information is separated from the failure point pointing information in the module and failure point pointing information can be lost due to human error. Never. In addition, there is no need to obtain approval from the user's destination for taking out the information on the location pointed out or the temporary leave.

(Example) Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an information processing apparatus according to an embodiment of the present invention.

The information processing unit FIM@1 has a diagnostic processing unit 2 and multiple seven-stage modules 2.
0+,202. ..., 2On.

Each module 201 to 20n is composed of electronic elements LS161 to 6n, and includes a logic section 21 that operates as the main function of the information processing device Wl1, a failure detection circuit 22 that detects a failure in the logic section 21, The IIl formation information register 23 records the operating state of the logic unit 21 at the time of failure, and the diagnostic processing unit 2 analyzes the failure formation.
Checkpoint JP, which stores information pointing out failure points within the system.
ttil memory made of removable non-volatile memory elements
7i! It is composed of a spot pointing information storage section 24.

The diagnostic processing unit 2 receives the failure occurrence signal issued from the failure detection circuit 22 and inputs the failure information register 23 of each module.
It consists of a diagnostic analysis unit 11 that extracts failure information from the computer and analyzes failure locations based on the failure information, and a failure dictionary 12 that stores correspondence data between failure information, failures, and locations. An output device 50 is connected to the information processing device 1, and the output device 50 analyzes the failure information collected from the failure information register 23 and compares it with the failure word 112. Outputs a summary of one point pointed out. Further, the diagnostic analysis unit 11 is connected to the failed VJ@place pointing information storage unit 24 of each module 20+ to 20n, and compares the failure information with the failure dictionary 12 to point out the failure module and the failure location within the failure module. . The information that pointed out the faulty g1 location in the faulty module is as follows:
The information is stored in the failure point pointing information storage unit 24 of the failure module. Information on faulty modules is output 1iI! 50 and indicates the module to be replaced for the maintenance name.

Next, the operation of the wooden dog embodiment will be explained.

Assume that a failure occurs in the lsI 62 in the logic section 21 of the module 201. The failure detection circuit 22 in the same module as the LSI 62 detects that an abnormality has occurred in the lsI 6a, and notifies the diagnostic analysis section 11 that an abnormality has occurred in the module 20+. Upon receiving this, the diagnostic analysis unit 11 collects failure information from the failure information register 23 of the module 201 . This reorganization information is compared with the failure judgment 12 to generate information pointing out the failure module and the failure location within the failure module.

The generated failure module indication information is sent to the output device 50 and outputted by the maintenance person. Further, the failure location pointing information in the failed failed module is sent to the failure location pointing information storage unit 24 of the failed module 201 and stored therein.

The maintenance person recognizes the faulty module from the information output from the output 1150, removes the module 20+ from the information processing device 1, and replaces it with the maintenance part. Module 20+ is sent to a repair department for repair. Module 2 in the repair department
0+ fault location information? a Read the failure point indication information from the storage unit 24, and then
Replace 2 and complete the repair.

〔Effect of the invention〕

As explained above, the present invention has a failure replacement unit of t%;
! ) By fixing the fault location identification information storage section in the module, the fault location identification information is not separated from the fault module, so there is no loss of fault location identification information due to a major mistake. There is no need to obtain prior approval to take out the failure point detection tri-report list, media, etc., and the failure module and failure point identification information can be sent to the repair department within a short period of time, which has the effect of shortening the repair time. be.
