Abstract

PURPOSE:To designate quickly and accurately a fault position of a subject system by comparing successively the data delivered from each computer system with the signal of a diagnosis supply means. CONSTITUTION:A computer 10 of a maintenance center controls a diagnosis program through a console 12 to a computer system 40 connected via a communication line 30 and a communication control part 20. Then the result of diagnosis is stored in a file 11. At the same time, a diagnosis program is controlled in the same way also with a computer system 41 which is connected via a communication line 31 and a communication control part 21. The result of diagnosis is stored in the file 11. These results of diagnoses are compared with each other, and the accurate fault position is obtained for the faulty computer system 40 based on the discordance data and a fault dictionary 13. This obtained fault position is transferred to the system 40.

にある。The present invention provides first and second communication control means connected to first and second computer systems that perform the same operation, respectively, via communication lines, and a communication control means connected to each of the computer systems via these communication control means. A diagnosis supply means for respectively supplying a predetermined fault diagnosis program; a comparison means for sequentially comparing data outputted from the valley computer system in response to a signal from the diagnosis supply means; The remote diagnosis method includes data output means for transmitting data to the computer system that has failed through the multiplication control means.

0.21, communication lines 30 and 31, a computer system 40 that happened to be out of order, a normally operating computer system 41, and a fault dictionary 13. now,
In the computer 10 of the maintenance center, the operation console 12 controls a diagnostic program for the failed computer system 40 connected via the communication line 302 and the communication control unit 20, and checks the machine clock or the diagnostic results at certain regular intervals. , e.g. collect register data,
It is stored in file 11.
