Abstract

PURPOSE:To make it possible to inform a doubtful device at the time of generating a device fault and to quickly execute the specific designation and restoration of a fault device in accordance with the maintenance operation result of each indivisual device in a stored program control type communication system. CONSTITUTION:After specifying a fault device and executing its restoration, a maintenance man inputs and stores fault history information for maintenance operation relating to a fault such as the date of fault generation, the sort of the fault, a fault device name, substituting result to a reserve device, and the repairing result of the fault device in a fault history data file B1 included in a station data file 12 in a main storage device 1 through a maintenance operation terminal 2. At the time of generating the device fault, a control device 3 outputs the fault history information to a maintenance operation terminal 2 based upon a diagnostic program A2 and informs a doubtful device corresponding to the maintenance operation result of each individual device in the storage program control type communication system.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication system maintenance operation system for automatically notifying a maintenance person of fault history data of individual devices when a fault occurs in a communication system.

[0002]

2. Description of the Related Art Conventionally, in a storage program control type communication system, a diagnostic program is started in order to diagnose a device related to this fault including a device in which a fault is detected when the fault occurs in the device. When an abnormality is detected, the suspected device with the highest possibility of failure, the suspected device with a possibility of failure, the suspected device with a low possibility of failure, and the possibility of failure from the diagnostic dictionary file stored in the main storage device. A maintenance operation method that reads information obtained in the design stage of a group of devices related to a suspected device that may have a failure indicated as a non-functional device and outputs the group of information related to this suspected device to a maintenance operation terminal. Has become.

[0003]

In this conventional communication system maintenance and operation system, a group of suspected devices obtained from the diagnostic dictionary file at the design stage of the device is shown as the diagnostic result by the diagnostic program when the device failure occurs. Either, or because the diagnosis result shows that it is good, it means that there was a failure in the device in the past and replaced it with a spare device,
Or the history of maintenance and operation related to the failure of individual devices such as repairing the failed device and incorporating it into the communication system, as well as the unique environmental conditions such as temperature, humidity and static electricity at the place where the communication system is installed. It was not possible to show the past history of the failed device based on the operational results of.

Therefore, there is a problem that it takes a long time to identify a faulty device and to recover from the fault when the fault occurs in the device in the storage program control type communication system.

[0005]

A communication system maintenance / operation system of the present invention is a maintenance / operation system in a storage program control type communication system having a diagnostic dictionary file, wherein the communication system obtains a result of operating the diagnostic dictionary file. The storage unit stores the acquired fault history information, and a control unit that automatically reads the fault history information from the storage unit and notifies the maintenance person when a fault occurs in the communication system.

The failure history information is characterized by including the date and time of failure, the type of failure, the name of the failed device, the cause of the failure, the presence or absence of replacement with a spare device, and the repair record of the failed device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of a storage program controlled communication system showing an embodiment of a communication system maintenance and operation system of the present invention.

The communication system maintenance and operation system of this embodiment is
The main storage device 1, the maintenance operation terminal 2, the control device 3, and a data channel 4 for transmitting and receiving data between the maintenance operation terminal 2 and the main storage device 1 according to an instruction from the control device 3 are provided. The main storage device 1 has a system file 11 including a diagnostic dictionary file A1 and a diagnostic program A2, and a station data file 12 including a fault history data file B1 that is sequentially changed according to operating station conditions.

In the fault history data file B1, after a faulty device is found and restored by a maintenance person based on a group of suspected devices printed on the maintenance and operation terminal 2 when a fault occurs, the date and time of fault occurrence and the type of fault , The failure history name in the maintenance operation related to the failure, such as the failure device name, the cause of the failure, the replacement record of the spare device, the repair record of the failure device, etc., is input from the maintenance person through the maintenance operation terminal 2 and stored. There is.

The operation of this embodiment will be described below assuming that a failure of the apparatus has occurred in this state.

The control device 3 executes a diagnostic program A2 for diagnosing devices related to the failure including a device in which the failure is detected.
When the diagnostic program A2 detects an abnormality in the device, it reads a group of suspected device names with a possibility of a failure from the diagnostic dictionary file A1, and further acquires failure history data relating to the suspected device. The data is read out from the data file, and the name of the group of suspected devices and the history information of past failures related to the suspected devices are printed out on the maintenance operation terminal 2.

Here, the maintenance person first has the highest possibility of failure by a predetermined procedure from a group of suspected device names printed on the maintenance and operation terminal 2 and history information of past failures related to the suspected device. Whether or not there is a failure in the suspected device is determined in the following order by determining whether or not there is a failure in the suspected device with the lowest possibility of failure.

Next, after the maintenance person finds and restores the faulty device by a predetermined procedure, the control device 3 determines the date and time of the fault, the type of fault, the faulty device name, the cause of the fault, and whether or not the spare device is replaced. Fault history information on maintenance and operation related to a fault such as a result of repairing the faulty device is newly stored in the fault history data file B1 via the data channel 4 by input from the maintenance and operation terminal 2 of the maintenance person.

In the present embodiment, the maintenance person can easily read the past history of the failed apparatus based on the maintenance operation results of the individual apparatuses of the stored program control communication system and notify the maintenance person, Therefore, the maintenance person can identify the faulty device and recover from the fault in a short time when the fault of the device occurs.

[0015]

As described above, according to the present invention, when a diagnostic program detects an abnormality of a device when a fault occurs in the device, the system automatically stores past fault history information of the suspected device involved in the fault. Therefore, the maintenance person can know the suspected device according to the individual maintenance operation record of the stored program control communication system, and can identify the failed device and restore the failed device in a short time. Have.
