Abstract

PURPOSE:To prevent the confusion occurring at a remote maintenance center at operation of the maintenance and to realize the effective maintenance diagnosis and at the same time to automatically inform fault information by providing a diagnostic bus control part and a microprogram execution control part, etc. CONSTITUTION:When an abnormality detecting means 22 set in a microprogram execution control part 20 detects the abnormality during the operation of a data processor, a control means 21 activates a fault information collecting means 23 to collect the fault information via a diagnostic bus 2 and a diagnostic bus control part 10. Then the means 21 discriminates the state of an operation mode switch 51 of a maintenance panel 50 via an operation mode deciding means 25. The means 21 activates a transfer means 24 in a normal operation mode to automatically report the fault information to a remote maintenance center. Then the means 21 inhibits the start of the means 24. Thus it is possible to prevent the confusion occurring at the remote maintenance center and to attain the effective maintenance diagnosis at operation of the maintenance. At the same time, the fault information is automatically informed.

Description

[Detailed description of the invention] [Industrial application field] INDUSTRIAL APPLICATION This invention is utilized for the diagnostic control apparatus of a data processing apparatus.

In particular, the present invention relates to a fault reporting method to a remote maintenance center in a data processing device in which a central processing unit, a main storage device, and a diagnostic control device for diagnosing these devices are connected via a diagnostic bus.

[4 Already Required] The present invention, in a data processing device, instructs the maintenance panel to select between normal operation mode and maintenance operation mode, and based on this instruction, fault information is reported to a remote maintenance center during normal operation, and during maintenance operation. By prohibiting notifications, it is possible to prevent confusion from occurring at the remote maintenance center during maintenance operations and to enable efficient maintenance diagnosis.

[Conventional technology]

Conventionally, a data processing device automatically reports failure information to a remote maintenance/diagnosis device when a failure occurs.

Remote maintenance and diagnosis devices are a method for quickly performing maintenance and diagnosis of data processing equipment without the need for maintenance personnel to visit the user.Recently, remote maintenance and diagnosis devices have also been improved, and when a failure occurs in the user equipment, fault information is automatically transmitted. Technology has been developed to enable notifications to be sent to a remote maintenance center. The user notifies the remote maintenance center of the occurrence of a fault, and the maintenance staff at the remote maintenance center who receives the notification connects to the user equipment via a communication line using the data processing equipment installed at the remote maintenance center, performs maintenance diagnosis, and collects the fault information. However, with the development of automatic fault reporting technology, remote maintenance centers can now automatically obtain fault information on user devices.

[Problem that the invention seeks to solve]

However, in such conventional data processing devices, a state that is considered to be a failure is inevitably created during periodic maintenance diagnosis or troubleshooting performed on the user device side. Since all such events are notified to the remote maintenance center, there is a drawback that the remote maintenance center becomes confused. Furthermore, in order to avoid such confusion, special operations such as forcibly disconnecting the line of the user equipment are required, which has the disadvantage of impairing maintainability.

The present invention solves the above-mentioned drawbacks, and provides a data processing device that can prevent confusion at a remote maintenance center during operation during maintenance, perform efficient maintenance diagnosis, and automatically report failure information. The purpose is to

[Means for solving problems]

The present invention includes a central processing unit, a main storage device, and a diagnostic control device connected to these two devices via a diagnostic bus, and the diagnostic control device includes a program execution control unit and a maintenance diagnosis. The program execution control section includes a maintenance panel means for performing a man-machine interface for the maintenance, and a line control section for controlling connection with a remote maintenance center. In the data processing device, the data processing device includes a transfer means for transmitting the dial number and failure information of the remote maintenance center to the line control unit under the control of the control means, and the maintenance panel means is configured to operate in a normal operation mode or a maintenance operation mode. The program execution control section includes a driving mode determining means for determining the instruction of the driving mode switch, and the control means is configured to determine whether or not the driving mode determining means is activated when a failure occurs. The present invention is characterized in that it includes means for activating the transfer requesting means when the determination result is in the normal operation mode, and prohibiting activation when the determination result is in the maintenance operation mode.

[Effect]

The operator operates the operation mode switch to instruct whether the mode is normal operation mode or maintenance operation mode. The operation mode determining means of the program execution control section determines the mode via the maintenance panel means. When a failure occurs, the control means activates the transfer means to automatically report the failure information to the remote maintenance center in the normal operation mode based on the determination result, and prohibits activation of the transfer means during maintenance operation. As a result of the above-described operation, reporting of failure information is prohibited during operation during maintenance, so that confusion does not occur at the remote maintenance center, efficient maintenance diagnosis can be performed, and failure information can be automatically reported.
