Abstract

PURPOSE:To reduce the cost of the communication line of the title system by utilizing a public telephone line for the automatic warning and remote maintenance control of a telephone exchange between a monitored controller and monitoring controller. CONSTITUTION:A monitored controller 3 is connected with a telephone exchange 1 and a monitoring controller 9 is provided in a maintenance center. Warning on the telephone exchange 1 and facilities of the office building is detected by the warning detecting section 4 of the device 3 and the telephone number of a warning signal sending destination is stored in a monitored storing section 6. When a monitored automatic originating and terminating section 7 automatically dials the telephone number of the warning signal sending destination, the originating process to a public telephone line 8 or terminating process of a call from the outside and the process to be performed when the use of the public line is terminated are performed. Moreover, the controller 9 cause a monitoring automatic originating and terminating section 10 to perform the originating process to the telephone line 8 and terminating process from the controller 3. Thus the cost of the communication line for remote maintenance of a telephone exchange can be reduced.

1 Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.
This is a diagram.

The telephone exchange remote maintenance system shown in FIG. The monitoring and control device 9 is connected to the monitored control device 3 through a telephone line 8, receives an alarm signal from the monitored control device 3, and transmits a control signal to the monitored control device 3.

The monitored control device 3 makes a telephone exchange tjifl! 11 and an alarm detection unit 4 that detects alarms from station equipment and sends out alarm signals.
, a monitored storage unit 6 that stores the telephone number assigned to the monitoring and control device 9 to which the alarm signal is sent, processes calls to the public telephone line 8 or processes incoming calls from outside, and processes when the use of the line ends. It is comprised of a monitored automatic call originating/receiving unit 7 and a monitored control unit 5 that controls the monitored automatic calling/receiving unit 7.

The supervisory control device 9 also includes an alarm receiving section 13 that receives an alarm signal transmitted from the monitored and controlled device 3, a display operation section 14 for displaying alarms and performing maintenance control of the telephone exchange 1, and a display operation section 14. A control transmitting unit 15 that sends out a control signal according to the operation of , a monitoring storage unit 12 that stores the telephone number of the monitored controlled device 3 to which the control signal is sent, and a call process to the public telephone line 8 or the monitored controlled device 3 The system is comprised of a monitoring automatic call originating/receiving unit 10 that processes incoming calls from the network and processing at the end of line usage, and a supervisory control unit 11 that controls the monitoring automatic call originating/receiving unit 10.

Next, the operation will be explained. In the alarm detection section 4,
When an 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 and is stored in advance in the monitored storage unit 6, and calls the monitored automatic call originating/receiving unit 7. Send to. The monitored automatic call originating/receiving unit 7 automatically makes a call to the supervisory control device 9 using this telephone number.

When the supervisory control device 9 and the monitored control device 3 are connected via the public telephone line 8, the monitored control section 5 connects the communication path of the monitored automatic call/receiver section 7 to the alarm signal transmission circuit of the alarm detection section 4. Connect with. The alarm detection section 4 transmits an alarm signal to the monitoring control device 9 of the maintenance center via the monitored automatic call origination/reception section 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 supervisory control device 9, and the monitored automatic calling/receiving unit 7 performs a process when line use is terminated, and the monitoring and control device 9 Public telephone line 8 connected between
The line connection will be canceled.

In the supervisory control device 9 , the supervisory control unit 11 connects the communication path of the automatic supervisory call/receiver unit 10 to the alarm receiving unit 13 . The alarm signal sent to the supervisory control device 9 is received by the alarm receiving section 13 and displayed as an alarm on the display operation section 14. An alarm transmission end signal is received from the monitored control device 3, and the automatic v-reporting ends.

Maintenance personnel who saw the alarm display remotely controlled telephone exchange 1.
When the control operation key of the display operation section 14 is operated in order to perform maintenance, the supervisory control section 11 to which the control information has been sent reads out the telephone number of the monitored control device 3 from the supervisory storage section 12 and starts the monitoring "automatic call/receiver section". 10 is activated, and automatic transmission to the monitored control device 3 is performed.

When the supervisory control device 9 and the monitored and controlled device 3 are connected via the public telephone line 8, the supervisory control unit 11 connects the communication path of the automatic supervisory call/receiver unit 10 to the control signal transmission circuit of the control transmitter 15. . The control transmitter 15 transmits a control signal to the monitored control device 3 via the automatic monitoring caller/receiver 10 .

After various necessary controls have been performed for the maintenance of the telephone exchange 1 by transmitting control signals, operating the control operation keys on the display operation section 1. The telephone line 8 is transmitted to the monitored control device 3 and processed by the automatic monitoring/receiving unit 10 to terminate the use of the line. The line connection will be canceled.

-H. In the monitored control device 3, when the public telephone line 8 is connected by a call from the monitoring control device Connect to input/output control device 2. Control signals transmitted from the supervisory control device 9 are 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 is completed, the remote control (2
When the maintenance end signal is received, the remote maintenance control ends.

In this way, when the automatic V alarm notification and remote maintenance control of the telephone exchange 1 do not use a dedicated line, but only one public telephone line 8 is required between the monitored and controlled device 3 and the monitoring and control device 9. It is possible to reduce the cost of communication lines.

1. Effects of the Invention] As explained below, the present invention enables automatic alarm reporting from a monitored and controlled device to a supervisory control device, and remote maintenance control from a monitored and controlled device to a telephone exchange by using a dedicated line. Instead, it is possible to connect and use one public telephone line each time it is needed, which has the effect of reducing the cost of communication lines.
