Abstract

A plant monitoring controller, provided with a monitor, that obtains process information from a plant and provides an operation signal to the plant, comprising: a process information database in which process information about the plant is recorded and accumulated; an operation video information database in which operation video information, which is video information displayed on a screen on the monitor, is recorded and accumulated as history information; and a history information database in which manipulation histories of the manipulable devices displayed on a screen on the monitor are accumulated as manipulation history information; wherein the process information, the operation video information, and the manipulation history information are recorded along with time information; and an operation video screen is provided as a screen displayed on the monitor, the operation video screen displaying a change from previous operation video information, read from the operation video information database, along with the time information.

Claims

1. A plant monitoring controller, provided with a monitor, that obtains process information from a plant and provides an operation signal to the plant, characterized in that;

the plant monitoring controller comprising;

a process information database in which process information about the plant is recorded and accumulated;

an operation video information database in which operation video information, which is video information displayed on a screen on the monitor, is recorded and accumulated as history information; and

a history information database in which manipulation histories of the manipulable devices displayed on a screen on the monitor are accumulated as manipulation history information;

wherein manipulable devices are displayed by being distinguished with each other on a screen given on the monitor;

the process information, the operation video information, and the manipulation history information are recorded along with time information; and

an operation video screen is provided as a screen displayed on the monitor, the operation video screen displaying a change from previous operation video information, read from the operation video information database, along with the time information.

2. The plant monitoring controller according to claim 1, wherein a manipulation state of a manipulable device on the screen displayed on the monitor is compared with previous manipulation histories recorded in the history information database, and if there is a matching manipulation history and the matching manipulation history indicates a problem caused in the past, the operation video screen is called and displayed.

3. The plant monitoring controller according to claim 2, wherein in correspondence to the operation video screen which has been called and displayed to indicate information at a previous time, information about the previous time is displayed.

4. The plant monitoring controller according to claim 1, wherein:

the operation video screen includes a video display area, a video manipulation area, a time scroll bar, and a date and time selection area; and

a change between observer manipulation screens in a specified period is displayed.
