Next, a flow from notification of a state change to control will be described with reference to FIG. As shown in step (hereinafter simply referred to as "S") 1, when a state change occurs in the monitored facility, a detection signal is transmitted from the monitored facility to the parent device via a wired line. Then, the parent device performs state change detection and text information notification for notifying the designated PHS of the state change detection. At this time, the history of the status change is stored in the database of the parent device.

Further, the remote monitoring and control system according to the present embodiment is capable of performing sequential broadcasting in which notification is performed in accordance with the priority order. After that, it is possible to set not to notify. Further, the remote monitoring control system according to the present embodiment can set an always-notifying PHS that always notifies when a change in the state is detected, and can perform retransmission for a PHS that has not been notified. It is possible.

Further, when the PHS receives a notification that the state change has been detected, as shown in S3, the PHS
The remote control using the parent equipment or the direct dispatch of the maintenance person to the site by using the system can deal with the occurrence of an abnormal situation.

The workflow of the PHS notification shown in S2 is as follows. In the PHS notification workflow in S2, first, as shown in S4, it is first determined whether there is a PHS setting that should always be notified. In S4, if there is a PHS setting to be always notified, the process proceeds to S5, and the PHS is notified.

At this time, in step S6, the PHS
If the notification to the user has failed, that is, if the holder of the constantly notified PHS does not respond to the notification, the process proceeds to S7, and determines whether the number of notifications of the state change detection has reached a predetermined number. Is determined, and if the predetermined number of times has not been reached, S5
And the same notification is repeated again. That is, if there is no response from the notified PHS, the notification is retransmitted up to a predetermined number of times. Also, S
In 4, if there is no PHS setting that should always be notified,
It is determined whether there is a PHS setting to be sequentially notified.

Next, in S8, after clearing the priority of the sequentially notified PHS, in S9, if there is no PHS to be sequentially notified, the process proceeds to S3. If there is a PHS to be set, the notification is made sequentially according to the priority.

In that case, first, in S10, the priority is set to “+1”. In S11, the first person is notified of the first priority. Next, S12
In step S1 if there is no response from the notified PHS
Proceeding to 3, it is determined whether or not the notification has reached a predetermined number. If the number of notifications has not reached the predetermined number in S12, the process returns to S11, and the notification is performed again.

If there is a response to the notification in S12, or if there is no response to the notification in S13 but the notification has been made a predetermined number of times, the process proceeds to S14, where it is determined whether or not the notified PHS is the PHS of the final rank. Is done. S
If it is the final rank, the process proceeds to S3, but if it is not the final rank, the process returns to S10 to increase the rank by one and notifies the PHS of the next rank.

Next, with reference to FIG. 21, as another example of the present embodiment, a remote monitoring control system in the case where an illegal intrusion into a radio station building will be described. In the remote monitoring control system of another example, when an illegal intrusion occurs in the wireless station building as shown in (1), it is input that the intrusion has been made to the parent device through the intrusion monitoring route. Then, the notifier A constantly from the parent device
Is notified to the PHS. The constant notifier A is, for example, a section manager, and is a holder of a constant notification PHS that is always notified regardless of any state change.

The notification is also made to the PHS of the notifier B in order as shown in FIG. The sequential notifier B has the first priority, and for example, the sequential notifier with the first priority is the chief. In addition, a notification is sequentially made to the PHS of the notifier C. This sequential notifier C is second in priority, and the sequential notifier C is, for example, a group leader. If the team leader could not be notified, that is, the team leader
If no response is received in S, the notification is retransmitted up to a predetermined number of times.

Further, the notification is sequentially made to the PHS of the notifier D. This sequential notifier D is third in priority and is the person in charge. PHS of each maintenance person
In (A), PHS (B), PHS (C), and PHS (D), for example, when it is detected that there is an illegal intruder to the equipment, there is an intrusion monitoring operation on the state detection screen. Is displayed.

Then, as shown in the remote control, an operation menu screen is displayed on the PHS of the person in charge, and when the person D selects "06 Control output setting" there is a screen on which an intrusion alarm can be performed. Is displayed. Therefore,
