In the monitoring control system according to the fifth embodiment, a monitoring screen in which an abnormality / failure occurs and the screen automatically shifts to the respective display areas 57a to 57z on the web browser of the web monitoring terminal in the first to fourth embodiments. The operator can select one monitoring screen from among those displayed, and only the selected monitoring screen can be fixed and displayed without automatically transitioning to the next monitoring screen.
For screens displayed in other display areas, a process of transitioning to the next monitoring screen is executed at regular intervals as in the first to fourth embodiments.

Hereinafter, the operation of the monitoring control system will be described in detail.
FIG. 21 is a diagram showing a state of the display screen in which screen fixing buttons are arranged.
FIG. 22 is a flowchart showing the operation of the Web monitoring terminal 550.
FIG. 23 is a flowchart showing operations for fixing and releasing the monitoring screen.
Note that the processing on the monitoring control server is the same as that in the first embodiment, and thus the description thereof is omitted.

The alarm information receiving unit 52 receives the alarm information notified from the monitoring control server using the web communication function 51 (S5100).
The alarm information receiving unit 52 delivers the received alarm information to the display control unit (S5101).
Based on the received alarm information, the display control unit displays each of the display screen number, screen name, display time, display area, display priority, automatic transition alarm level, screen display condition, and related item number from the monitor screen database 454. Information is acquired (S5102).
Further, the display control unit displays the display screen number, the screen name, the display time, the display area, the display of the monitoring screen displaying this item number from the item number of the monitoring equipment defined in the related item acquired in S5102. Each information of the priority, the automatic transition warning level, and the screen display condition is acquired from the monitoring screen database 454 (S5103).

The display control unit acquires the layout information of the monitoring screen to be displayed from the screen information definition 55 (S5104).
The display control unit selects monitoring screen information having a high display priority from the monitoring screen information acquired in S5102, S5103, and S5104 (S5105).
The display control unit determines whether the alarm level of the alarm information notified from the monitoring control server is equal to or higher than the automatic transition alarm level (S5106).
When the alarm level is equal to or higher than the automatic transition alarm level, the display control unit determines whether the generated alarm corresponds to the screen display condition set for each monitoring screen (S5107).
When the generated alarm corresponds to the screen display condition set for each monitoring screen, the display control unit determines whether there is a display area where the display of the monitoring screen is not fixed (S5108).

When there is an unfixed display area, the display control unit notifies the monitor screen information to the screen display units 5a to 5z included in the display regions 57a to 57z (S5109).
If there is no display area that is not fixed, the process waits until a display area that can automatically change the monitoring screen is generated (S5110).
The monitoring screen display is fixed when the monitoring screen displayed in the display areas 57a to 57z is continuously monitored by pressing the screen fixing button displayed in each display area 57a to 57z of the display device. The operator presses the screen to fix the display (S5200).
On the other hand, when the monitoring screen display fixed in the display areas 57a to 57z is terminated, the screen lock button displayed in each display area 57a to 57z of the display device is released. The operator presses again to cancel the screen display fixation (S5300).
The screen display units 5a to 5z display the notified monitoring screen information in the display areas 57a to 57z on the display device (S5111).
The display control unit repeats the processing of S5105 to S5111 unless the operator designates the end of the monitoring screen automatic transition processing (S5112).

In the conventional system, the monitoring screen is changed in a predetermined order every predetermined time, and the screen that the operator needs to continuously monitor also changes automatically.
According to the monitoring control system according to the fifth embodiment of the present invention, when the operator selects a screen that needs to be continuously monitored, the screen can be fixed and displayed in each of the display areas 57a to 57z.
This eliminates the need to wait until the target monitoring screen that has once disappeared is displayed again, and saves the operator from performing the process of transitioning to an individual monitoring screen, thereby improving work efficiency. it can.

  It should be noted that the present invention can be freely combined with each other within the scope of the invention, and each embodiment can be appropriately modified or omitted.
