〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the system configuration of an embodiment of the present invention.

The telephone exchange remote maintenance system shown in FIG. 1 is connected to the telephone exchange input / output control device 2 and the station building equipment, and monitors the telephone exchange 1 and the station building equipment, and the monitored control device 3 for controlling the telephone exchange 1 and the public. The monitoring control device 9 is connected to the monitored control device 3 via a telephone line 8 and receives a warning signal from the monitored control device 3 and transmits a control signal to the monitored control device 3.

The monitored control device 3 stores a telephone number assigned to the alarm detection unit 4 that detects an alarm of the telephone exchange 1 and the station equipment and sends an alarm signal, and the monitoring control device 9 to which the alarm signal is sent. Monitored storage unit 6, monitored telephone automatic call incoming / outgoing unit 7 for performing outgoing call processing to public telephone line 8 or incoming call processing from the outside and processing at the end of line use, and monitored control for controlling monitored automatic call incoming / outgoing unit 7 It consists of part 5.

The monitoring control device 9 also receives an alarm signal transmitted from the monitored control device 3, an alarm receiving unit 13, a display operation unit 14 for displaying an alarm and performing maintenance control of the telephone exchange 1, and a display operation unit 14 Control transmission section 15 for transmitting a control signal by the operation of
The monitoring storage unit 12 that stores the telephone number of the monitored control device 3 to which the control signal is transmitted, the calling process to the public telephone line 8 or the incoming process from the monitored control device 3 and the process at the end of line use. It comprises a monitoring automatic transmission / reception unit 10 for performing and a monitoring control unit 11 for controlling the monitoring automatic transmission / reception unit 10.

Next, the operation will be described. In the alarm detector 4,
When the alarm is detected, the monitored control unit 5 reads the telephone number of the monitoring control device 9 of the maintenance center, which is the destination of the alarm signal, stored in the monitored storage unit 6 in advance, and the monitored automatic call-in / out unit 7 is read. Send to. The to-be-monitored automatic transmission / reception unit 7 automatically makes a call to the monitoring control device 9 using this telephone number.

When the monitoring control device 9 and the monitored control device 3 are connected via the public telephone line 8, the monitored control unit 5 causes the alarm signal transmission circuit of the alarm detection unit 4 to connect the communication path of the monitored automatic calling / receiving unit 7 Connect with. The alarm detection unit 4 transmits an alarm signal to the monitoring control device 9 of the maintenance center via the monitored automatic call originating / receiving unit 7. When the transmission of the alarm signal is completed, an alarm transmission end signal is transmitted from the monitored control unit 5 to the monitoring control device 9, and the monitored automatic calling / receiving unit 7 performs processing at the time of ending the line use, and the monitoring control device 9 The line connection of the public telephone line 8 that has been connected between and is released.

In the supervisory control device 9, the supervisory control unit 11 connects the communication path of the supervisory automatic transmission / reception unit 10 to the alarm receiving unit 13. The alarm signal transmitted to the monitor control device 9 is received by the alarm receiving unit 13 and displayed on the display operation unit 14. Upon receiving the alarm transmission end signal from the monitored control device 3, the automatic alarm notification ends.

Maintenance personnel who saw the alarm display remotely controlled the telephone exchange 1
When the control operation key of the display operation unit 14 is operated to maintain the
The telephone number of the monitored and controlled device 3 is read from 12 to activate the monitoring / automatic transmission / reception unit 10 to automatically make a call to the monitored and controlled device 3.

When the supervisory control device 9 and the supervised control device 3 are connected via the public telephone line 8, the supervisory control unit 11 causes the supervisory automatic transmission / reception unit.
The 10 communication paths are connected to the control signal transmission circuit of the control transmission unit 15. The control transmission unit 15 transmits the control signal to the monitored control device 3 via the monitoring automatic transmission / reception unit 10.

When the control operation key of the display operation unit 14 is operated after various controls necessary for maintenance of the telephone exchange 1 are performed by transmitting the control signal, a remote maintenance end signal is sent from the control transmission unit 15 to the monitored control device 3 Is transmitted to the public telephone line 8 which is connected between the monitored control device 3 and the monitoring control device 9, and the line connection of the monitored control device 3 and the monitoring control device 9 is released. It

On the other hand, in the monitored control device 3, when the public telephone line 8 is connected by the call from the monitoring control device 9, the monitored control unit 5 causes the monitored automatic call originating / receiving unit 7 to switch the input / output of the telephone exchange. It is connected to the control device 2. The control signal transmitted from the monitor control device 9 is received by the telephone exchange input / output control device 2, and various controls necessary for maintenance of the telephone exchange 1 are performed. When the control ends and the remote maintenance end signal transmitted from the monitoring controller 9 is received, the remote maintenance control ends.

As described above, the automatic alarm notification and the remote maintenance control of the telephone exchange 1 do not use a dedicated line, but only when one public telephone line 8 is required between the monitored control device 3 and the monitoring control device 9. This is possible by using it, and the cost of the communication line can be reduced.

〔The invention's effect〕

As described above, the present invention does not use a dedicated line when performing automatic alarm notification from the monitored control device to the monitoring control device and remote maintenance control from the monitoring control device to the telephone exchange, and does not use a public telephone line. It is possible to connect and use one line each time it is needed, and it is possible to reduce the cost of the communication line.
