2. Description of the Related Art Conventionally, in a telephone exchange system, information for managing the implementation or use of devices and circuits has been put into a database as exchange facility station information data and stored in an external storage device such as a hard disk. As a well-known technique for converting the equipment configuration information in such a communication network into a database, for example, there is a technique disclosed in JP-A-2-73731. In this technology, a plurality of equipments automatically collect configuration information of a network connected to each other and create a database, and other equipment connected to equipment ledger information of each equipment configuring a communication network. The equipment ledger information of the equipment and their connection relation information are added and transferred to the center for checking, and a network configuration management database is created.

The outline of this prior art will be described with reference to FIG. First, it is determined whether the collection of facility information is collective or collective (step S901). In the case of collective collection (Y), for example, in the case of collective collection performed periodically once a year, step S902 is performed. From step S909. In the case of change (when the equipment change work is completed)
(N), the processing shifts to the next processing. In contrast, in the case of batch collection (step S901: Y), first, the facility information collection unit of the center issues a transfer instruction to the communication devices of all devices constituting the communication network (step S902). Equipment ledger information (for example, model: micro terminal, manufacturer: A factory, model: K type, manufacturing year: 63 years, stored in the memory (ROM: read only memory) of
(Installation location: Oi substation, etc.) (Step S903) Then, the equipment which has received the information transfer instruction in Step S902 issues an information transfer request via a connection line to all other equipment which is connected to the own equipment (connection, opposite, relay, etc.). (Step S904), and in response to the transfer request,
The equipment ledger information read from the memory and transferred by the partner equipment is received (step S905).

Next, the attributes (equipment ledger information) of the own equipment and the partner equipment are transferred to the center (step S906), and the network configuration of the center is checked by the checking unit, and the equipment ledger transferred from each equipment is checked. Based on the connection information added to the information, the relationship (connection,
It is checked whether or not the opposition, relay, etc.) are correct in view of the mutual relationship between the facilities (step S907). Step S
The connection relation added to the equipment ledger information checked as being correct in the processing at 907 is mutually connected to form the entire communication network (step S908), and the connection processing result is divided to divide the network configuration management database. (Step S
909).

In accordance with the above processing, each facility receives the equipment ledger information of its own equipment and the equipment ledger information of the other equipment which is connected, opposed, relayed, etc. in response to the batch instruction from the center. The network configuration management database can be created based on the data transferred to the center.

Further, as shown in Japanese Patent Application Laid-Open No. H5-114093, in a building equipment remote monitoring system, necessary information about each of the above equipment is stored in advance in a database attached to a host computer of a monitoring center, and an elevator or the like is used. When the terminal device detects an abnormality in the operation of the monitored equipment, the necessary data relating to the abnormal equipment is automatically acquired from the database, and the data is automatically transmitted to maintenance personnel. was there.

The above-mentioned telephone exchange facility station information database does not secure a storage capacity corresponding to the maximum facility capacity in order to use the storage capacity efficiently, but instead reserves the capacity in accordance with the facility scale of the device / line. If the equipment has been secured and equipment has been added or removed, as in the case of the known technology described above, the maintenance person will be required to add or remove equipment station data along with the work. Command (H
MI command) to add or delete station data information.

[0008]

However, in the above-mentioned method, the station information data for the addition or the reduction of the station information data accompanying the addition or the reduction instructed by the maintenance person in proportion to the equipment to be added or reduced is provided. The number of HMI commands, which are maintenance commands, has also increased, and as a result, the workload of maintenance personnel has also increased. Further, the storage portion in which the station information data which is no longer used due to the reduction is written remains as it is and is not reused, and the storage capacity of the storage device is not efficiently used.

[0009]

A failure monitoring timer 56 is provided in the device / line monitoring controller 53. Further, a storage device 61 for storing the station information database of the line is provided so as to be connected to the database read control unit 54 in the processing device 51.

A line device (11, 12, 13,..., 31, 32, 33,.
..) Is added or removed, the interface signal distribution control unit 52 of the processing device 51 receives the device / line mounting notification signal by the interface signal. This device
The line mounting notification signal includes device or line type information, accommodation position information, and the like. The interface signal distribution control unit 52 analyzes the device / line mounting notification signal and requests the database read control unit 54 to read the corresponding station information data from the device or line type information and the accommodation position information. The database read control unit 54 receives the read request and stores the corresponding station information data in the storage device 61.
Read from As a result of the read request, the device / line monitoring controller 53 monitors and controls whether the corresponding station information data is to be added or deleted, or whether a fault has been recovered or a fault has occurred. The failure monitoring timer 56 is a timer for monitoring the state of failure recovery or failure occurrence. The database update control unit 55 includes a database read control unit 54

If you add the station information data A ₃ for the third line 13, the station information data table T _a3 is added, to ensure a memory area M _a3 connecting linkage T _a3 and M _a3. If you remove the station information data B ₃ of the third line 33, the station information data table T _b3 is removed, performs area free storage M _b3, T _b3
And the linkage of M _b3 are cut.

The automatic maintenance processing operation of the automatic maintenance device of the telephone exchange facility configured as described above will be described with reference to FIGS.

FIG. 3 and FIG. 4 show processing operations when the line is added and when the existing line is restored. First, a processing operation when a line is added will be described. When the third line device 13 is added to the first line control device 21 (step S101), a device / line mounting notification signal is transmitted from the first line control device 21 by an interface signal (step S102). This signal is received by the interface signal distribution control unit 52, and the signal type in the signal,
The accommodation position is analyzed (step S103). This analysis result is transmitted to the device / line monitoring controller 53 (step S104). The device / line monitoring control unit 53 determines the line (the first line control device 21 + the third line device 1) from the analysis result.
A request for reading the station information data of 3) is made. (Step S105) The database read control unit 54 reads the station information data based on the database access key of the specified line (for example, (first line control device 21 + third line device 13)). At this time, since the station information data has not been read yet, the database read control unit 54 returns a "no station information data" flag to the device / line monitoring control unit 54 (step S106). The device / line monitoring controller 53 determines this result (step S10).
7), a new request for station information data is made as a new addition of a line (first line control device 21 + third line device 13) (step S108). The database update control unit 55 receives the new request, secures a storage area for the station information data of the line (first line control device 21 + third line device 13) (step S109), and stores the table _Ta3 and the table _Ta3 . connecting linkage between the storage region M _a3 reserved (step S110) (see FIG. 2). Subsequently, the state of the line (first line control device 21 + third line device 13) is updated to the secured storage area Ma3 (step S11).
1).

Next, the line (first line controller 21 + second line controller 21)
The case where the line device 12) has recovered from the failure will be described. Line (first line control device 21 + third line device 1)
When 3) recovers from the failure (step S101), similarly to the line addition processing, the line control device 1 transmits a device / line mounting notification signal by an interface signal (step S102). This signal is received by the interface signal distribution control unit 52, and the signal type and the accommodation position in this signal are analyzed (step S103). This analysis result is transmitted to the device / line monitoring controller 53 (step S10).
4). The device / line monitoring control unit 53 determines the line (first line control device 21 + second line device 12) from this analysis result.
Request to read the station information data (step S10).
5). The database read control unit 54 specifies the designated line (the first line controller 21 + the second line device 12).
The station information data is read based on the database access key. In the case of failure recovery, since the station information data exists, the database read control unit 54 returns a "station information data present" flag to the device / line monitoring control unit 53 (step S106). The device / line monitoring controller 53 determines this result (step S107), and enters a failure recovery process (step S121). First, the failure monitoring flag is turned off in the device / line monitoring controller 53, and the failure monitoring timer is set. The timer value of 60 is cleared (step S122), and a line status update request is made to the database update controller 55 (step S123). The database update control unit 55 updates the state of this line (the first line control device 21 + the second line device 12) in order to set the line state to "normal" (step S124).

FIGS. 5 and 6 show the case where the number of lines is reduced.
This shows the processing operation when an existing line fails. When the third line device 33 is removed from the second line control device 41 (step S301), a device / line mounting notification signal is transmitted by an interface signal (step S30).
2). This signal is received by the interface signal distribution control unit 52 in the processing device 51, and the signal type in this signal,
The accommodation position is analyzed (step S303). This analysis result is transmitted to the device / line monitoring control unit 53 (S304). The device / line monitoring control unit 53 determines the line (the second line control device 41 + the third line device 3) from the analysis result.
The request for reading the station information data of 3) is made to the database read control unit 54 (step S305). The database read control unit 54 reads out the station information data based on the database access key of the designated line (the second line control device 41 + the third line device 33) (step S306). In this case, since the corresponding station information data exists, both the “corresponding station information data present” flag and the corresponding station information data are transmitted to the device / line monitoring controller 53 (step S307). Equipment / line monitoring control unit 5
In step 3, it is determined from the above-mentioned flag that there is "applicable station information data", and the processing for line reduction is started (step S30).
8). The fault monitoring flag is turned on in the station information data of the line (the second line control device 41 + the third line device 33), and an n value (n is a positive integer) is input to the fault monitoring timer (step S309). Subsequently, the device / line monitoring control unit 5
3 requests the database update control unit 55 to update the state of the line (second line control device 41 + third line device 33) (step S310). The database update control unit 55 updates the station information data in order to set this line state to the "normal" state (step S311).

By setting a failure monitoring flag and a failure monitoring timer, it is determined whether the system is a reduction or a failure in a failure monitoring cycle process described later.

FIGS. 7 and 8 show a fault monitoring cycle process for monitoring and controlling whether a line has been reduced or a fault has occurred. The fault monitoring cycle process is started in a cycle of m (m is a positive integer) seconds, and reads station information data from the device / line monitoring control unit 53 for each mounting line sequentially from the line with the smallest number first. A request is made (step S401). In response to the read request, the database read control unit 54 reads out the station information data for each line, and corresponds to the line database access key (the second line control device 41 + the third line device 33) of the read station information data. The line station information data is returned to the device / line monitoring controller 53 (step S
402). In this embodiment, processing is performed so that station information data of the next line is read for each read request, and when reading of all mounted station information data is completed, a flag of “all data read end” is returned (step S40
3). The device / line monitoring control unit 53 determines the result based on the database access key, the station information data, and the flag from the database read control unit 54, and ends the process if "all data read is completed". Otherwise, the fault monitoring flag of the station information data is checked (step S404). If the fault monitoring flag is off, the process proceeds to step S401. If the fault monitoring flag is on, the fault monitoring timer 6
The m value is subtracted from the timer value of 0 (step S405).

Next, the monitoring timer value after the subtraction is determined (step S406). If the monitoring timer value is larger than "0", the process proceeds to step S401. To the device / line monitoring controller 53 via the interface signal distribution controller 52 (step S407), and the interface signal distributor 52 transmits the read result to the device / line monitoring controller 53 (step S408). The device / line monitoring control unit 53 detects whether or not the line is mounted (step S409). If the line is not mounted, it is determined that the line has been reduced, and the line (the Line control device 41 of 2
+ A data update request is issued to the database update control unit 55 to delete the station information data of the third line device 33) (step S410). In response to the data update request, the database update control unit 55 deletes the station information data (step S411) and disconnects the linkage between the station information data table _Tb3 and the storage area _Mb3 (step S41).
2) (see FIG. 2). The deleted storage area is managed as a free area and is reused when a new line is added.

If it is determined in step S408 that the line is mounted, the line is determined to have a failure, and a request for updating the station information data is made (step S408).
413), the line (second
The station information data of the line control device 41 + the third line device 33) is updated (step S414).
