Abstract

PURPOSE:To eliminate a private circuit for fault service and to simplify the arrangement of maintenance men by switching a circuit to be used at normal operation from the normal operation circuit controlling part side to the remote maintenance controlling part side at the detection of the failure to access a maintenance center. CONSTITUTION:The normal operation circuit controlling part 12 can be connected to an MODEM14 and a network controlling unit 16 through the remote maintenance controlling part 30. The remote maintenance controlling part 30 selectively connects the normal operation circuit controlling part 12 or the self-circuit controlling part to the MODEM14 or the network controlling unit 16 in accordance with the generation of a failure in a data processor 10. Receiving the information of failure generation from the remote maintenance controlling part in each data processor, the remote maintenance center 32 executes a diagnosis program automatically to execute the automatic diagnosis of the data processor.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a system for diagnosing and maintaining a data processing device using a remote data processing device.

(2) As a remote maintenance method for private point data processing equipment compared to the conventional technology,
There is a method as described in Japanese Patent No. 0622. In this method, a microprogram-controlled service processing device is installed in each data processing device, and a diagnostic microprogram sent from the maintenance center is executed in the service processing device and the results are sent back to the maintenance center. It is. In this case, for the IWIK between the data processing device and the maintenance center, a line dedicated to remote maintenance, separate from that used during normal operation, is set up using a public telephone line or the like.

FIG. 1 shows an outline of a conventional computer protection system including this type of system, in which 10 indicates a data processing device to be diagnosed;
12 is a line control unit used by YtC during normal operation, 14 is a modem, 16 is a network control unit,
18 is a telephone network, 20 is a maintenance center, and 22 is a terminal. If there is no abnormality in the data processing device 10, the data processing device 10 is normally operated by the line control unit 12.
, modem 14, network control unit 16
, and a telephone line network 18 to the terminal 22. When a failure occurs in the data processing device 10, the on-site operator or maintenance personnel assigned to the data processing device recognizes this, and the remote maintenance control unit 24, modem 26, network control unit 78, and telephone circuit network 18
The data processing device 10 is connected to the maintenance center 2 through this route, and the data processing device diagnosis as described above can be performed from the maintenance center 201111I.

As mentioned above, according to the prior art, it is necessary to provide a remote maintenance line in the event of a failure separately from the normal line, which has the problem of considerably increasing costs. Sweet/
(It is necessary to ask the operators or maintenance personnel who are unable to recognize the failure of each data processing device ifi: 7. However, it is necessary to conduct standard operation training, which is a considerable burden.In addition, it is required that all full-time staff be stationed at the medical center.

(3) Purpose of the Invention Therefore, the present invention solves the two problems of the prior art. There is no need to set up a separate line from the regular line, and there is no need to worry about placing maintenance personnel on the side of each port processing equipment.Furthermore, it is not necessary to have a dedicated person on the side of the maintenance center, which is a remote information processing equipment. The purpose is to provide a system of security that does not need to be permanently stationed.

(4) A feature of the present invention that achieves two objects in 11% of the scope of the invention is that a plurality of data processing devices can be stored as remote data processing devices.
It is a system that diagnoses and maintains from the Hinta side, and the data processing device is a public telephone island! 1till (ILT 1 part and the data processing equipment are detected for failure, and when a failure is detected, the public communication line used during normal operation is The main feature is that a remote maintenance system 1j section is provided to switch from the normal operation line control section side to the own side and call the maintenance center.

(5) Embodiment of the Invention FIG. 2 1d is a diagram schematically showing an embodiment of the present invention, and FIG. 3 is a diagram showing in detail the remote maintenance control section in FIG. 2.

FIG. 2 shows a data processing device to be diagnosed 10, a normal operation line control unit 12, a modem 14, a network control unit 16, 14 (1 talk line network 18, and a terminal 2).
1;I is the prior art of FIG. 1 and the total <1-''. However, the normal operation line! The TI control section 12 can be connected to the modem 14 and the network control unit via the remote maintenance control section 30. The remote maintenance control unit 30 connects the normal operation line control unit 12 or its own line:b' control unit to the mobile unit 14 and network control unit 16 depending on whether a failure has occurred in the data processing device 10 or not. Connect selectively. That is, in the present invention, the line used during normal operation is also used as the remote maintenance line (7) when a failure occurs.

. When the remote maintenance center 32 receives a notification of the occurrence of a failure from the remote maintenance control unit of each data processing device σ), it automatically executes a diagnostic note program and performs a complete automatic diagnosis of the data processing device.

Next, the configuration and operation of the remote maintenance Hf control unit 30 will be explained in more detail with reference to FIG.

The microprocessor 30b causes the failure detection circuit 30c to constantly or periodically detect failures in the data processing device 10 according to the program stored in the program memory. Data processing of 1. O
If an obstacle or cloud occurs, the failure will occur.
”, Micro 70 Rose and The 30 b V all agree.

From now on, the direct line switching [four-way 30d has been activated, and the modem 14 and network control unit 14, which had been in normal operation until now, have been switched to Switch to the line control circuit 1; 3o e and automatic transmission circuit 30f side. And automatic outrage circuit, 3
Of, the maintenance center 32 is called completely automatically. the result,
Automatic diagnosis is started by the maintenance center 32. The interface circuit 30g is used for coupling with the data processing device 10 in this case.

When the automatic diagnosis is completed, the microprocessor 30bd,
The line switching circuit 30d is operated, and the line is switched to the normal operation line control unit 12 side.

Note that if you connect the remote maintenance control unit to the maintenance center by switching the line not only in the event of a failure, but also periodically, the maintenance center will not be able to determine the status of the data processing equipment. I can do it.

(6) Effects of the Invention As explained in detail above, according to the present invention, when a failure is detected, the line that can be arbitrarily connected and used during the 1/C tracing operation is transferred from the normal operation line control unit Since the switch is made to the remote maintenance control unit side and the maintenance center is called, there is no need to set up a dedicated line for troubleshooting services separately from all normal lines, and maintenance staff, etc. are required to be on each data processing equipment side. There is no need to place That's naive. There's no need to have a dedicated person stationed at the maintenance center all the time. Therefore, the cost of the line is reduced accordingly, and various problems caused by having maintenance personnel and dedicated personnel are also solved.
