Therefore, it is possible to easily call the detailed information screen, and there is an effect that it is possible to smoothly narrow down to the detailed monitoring of the narrow area sequentially from the outline monitoring of the wide area through a plurality of stages.

According to the present invention, the other system database and the other system large screen display processing unit are provided in the large screen processing device, and when an abnormality occurs in another monitoring control device connected via the linking device, the other system is processed. The system large screen display processing unit breaks down a part of the large screen display device based on the screen data for displaying the screen display information of another monitoring control device held by the other system database on the large screen display device. Is configured to display the screen display information of the other monitoring and control device, so that even if a failure occurs in another monitoring and control device and the monitoring control becomes impossible, the backup system of the other monitoring and control device is not required. There is an effect that can be operated as.
