Further, the centralized supervisory control devices 13a-13b are provided.
When the centralized monitoring controller 12a is operating normally, the centralized monitoring controller 12a manages the monitoring information from the remote monitoring controller, and when the centralized monitoring controller 12a fails, the centralized monitoring controller 12a collects the monitoring information. Supervisory control device 1
2b manages and receives the monitoring information from the remote monitoring control device.

The information relay device 11 receives the monitoring information from the remote monitoring control device via the communication line 14, and according to the initial information received from the centralized monitoring control device 12a or the centralized monitoring control device 12b at the time of initial system startup.
The monitoring information from the remote monitoring control device is transferred to the corresponding centralized monitoring control devices 12a, 12b, 13a-13b, respectively.

Next, the centralized supervisory control device 12a shown in FIG.
In the system configuration information holding means 9, the configuration information of the monitoring target items of the centralized supervisory control system and the device configuration information of the centralized supervisory control system are stored.

First, at the time of initial system startup, the system configuration information management means 8a reads out the configuration information of the entire monitoring target and the device configuration information of the centralized monitoring control system which are stored in advance in the system configuration information holding means 9,
Initial information a, which is information indicating the correspondence between each centralized monitoring control device and the monitored target item, indicating which monitoring target item is to be monitored by each centralized monitoring control device, and each centralized monitoring control device are assigned. Initial information b indicating the configuration information of the monitoring target item and initial information c including the configuration information of the entire monitoring target and the information indicating the correspondence between each centralized monitoring control device and the monitoring target item are created.

Then, the created initial information a is sent to the information relay apparatus 11. When receiving the monitoring information from the remote monitoring control device, the information relay device 11 creates an information table serving as a criterion for determining to which centralized monitoring control device the monitoring information should be sent when receiving the monitoring information from the remote monitoring control device.

Further, the initial information b created by the system configuration information management means 8a is the centralized monitoring control device 12a.
It is sent to its own monitoring control means 1, to the system configuration information management means 8b of the centralized monitoring control device 12b, and to the monitoring control means 1 of the centralized monitoring control devices 13a to 13b. Upon receipt of this initial information b, the system configuration information management means 8b of the centralized monitoring control device 12b sends this initial information b to its own monitoring control means 1. In this way, each monitoring control unit 1 receives the initial information b as the configuration information of the monitoring target to be processed by the own device, and stores this in the initial information holding unit 2 of the centralized monitoring control device of the own device.

Next, the initial information c created by the system configuration information management means 8a is sent to the display information creation means 4 of the centralized monitoring control device 12a itself, and the system configuration information management means of the centralized monitoring control device 12b. 8b, and also to the display information creating means 4 of the centralized supervisory control devices 13a-13b. Upon receiving the initial information c, the system configuration information management means 8b of the centralized supervisory control device 12b sends it to the display information creation means 4 of its own device. Then, each display information creating unit 4 receives the initial information c as the configuration information of the monitoring target to be processed by the own device,
The configuration information of all the monitoring targets is converted into information for creating a screen, and this is stored in the screen information holding means 5 of the centralized monitoring control device of the own device.

Next, at the time of normal operation, each monitor control means 1 stores the monitor information received from the information relay device 11 as the monitor information a in the monitor information holding means 3 and detects the state change to change the state. The information is output as monitoring information b. Then, each display information creating means 4 receives the monitoring information b from the monitoring control means 1, converts it into a display request based on the information in the screen information holding means 5, and outputs it.
Then, the display management means 6 receives this display request,
It is displayed on the display means 7 according to the display request content.

Next, a case where a failure occurs in the centralized monitoring control device 12a will be described.

The system configuration information management means 8b of the centralized supervisory controller 12b periodically sends an operation confirmation signal to the centralized supervisory controller 12a in order to check the operating state of the centralized supervisory controller 12a. If there is no response from the confirmation signal and it is determined that a failure has occurred, the initial information a
Is sent to the information relay device 11 and immediately performs the same operation as the system configuration information management means 8a of the centralized monitoring control device 12a, and the centralized monitoring control device 12b shifts to the alternative operation of the centralized monitoring control device 12a. That is, in the information relay device 11, the information table serving as a criterion for determining to which centralized monitoring control device the monitoring information should be sent is rewritten by the initial information a. The centralized supervisory control device 12b manages the centralized supervisory control devices 13a to 13b, and the monitoring information received and processed by the centralized supervisory control device 12a before the failure occurs is also centrally monitored and controlled by the information relay device 11. It is sent to the device 12b and displayed.

In this way, the correspondence relationship between the centralized supervisory control device and the supervisory information sent from the remote supervisory control device, which is received by the centralized supervisory control device, is determined by setting the initial value when the system is started up. By providing the system configuration information management means so that even if one central management control device out of a plurality of central monitoring control devices fails, the monitoring target assigned to the central monitoring control device is monitored. Information can be automatically backed up, received, and displayed by another centralized monitoring and control device, and the reliability of the system can be improved.
