DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant monitoring device for monitoring the occurrence of an abnormality in a plant.

[0002]

2. Description of the Related Art For example, a plant monitoring device for monitoring an industrial plant such as a power plant monitors whether or not process data such as temperature, pressure and flow rate of each part of the plant is within a normal range. FIG. 13 shows a conventional plant monitoring device.

In FIG. 1, a plant monitoring device includes a process input device 2 for inputting process data from a plant 1 at a predetermined timing, an operation control device 3 for performing predetermined monitoring and automatic display, Storage device 4 for storing data and automatic output screen table
And a display device 5 for displaying monitoring information, and an input device 6 for an operator to select and input a menu.

[0004] In the arithmetic and control unit 3, the data collection processing means 7 stores the process data input from the process input device 2 in time series by the collected data storage means 13 of the storage device 4.

[0005] The event detection processing means 8 determines whether or not the process data input from the data collection means 7 satisfies an event occurrence condition.
The automatic output screen processing means 9 is notified that an event has occurred.

[0006] When the event detection is notified from the event detection processing means 8, the automatic output screen processing means 9 reads the display screen corresponding to the event from the automatic output screen table 14 and notifies the screen editing / display processing means 11. . The screen editing / display processing unit 11 reads the process data in the collected data storage unit 13, performs an editing process on a corresponding screen, and outputs the processed screen to the display device 5.

FIG. 14 shows an example of an automatic output screen. When switching to another screen according to an event in addition to one automatically output screen, the operator calls a menu screen from the input device 6 and sets a screen request. The menu processing means 17 receives a request from the operator and notifies the screen editing / display processing means 11 of the requested screen.

FIG. 15 shows an example of a menu screen. As described above, the screen is automatically output when an event occurs, and the subsequent screen switching monitors the plant by selecting the screen from the menu.

[0009]

In the conventional plant monitoring apparatus, the display device 5 is generally constituted by one unit, and one screen is automatically output. Therefore, other screens that need to be confirmed when an event occurs are required. (Switch screen) was manually selected by the operator.

As shown in FIG. 15, a switching screen is displayed by requesting display of an event menu from the input device 6 and sequentially setting submenus. Therefore, it takes time to verify the data, and an operation error may occur.

SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem, and an object of the present invention is to provide a plant monitoring apparatus capable of reducing an operator's work when an event occurs.

[0012]

According to the present invention, there is provided a plant monitoring apparatus which monitors process data input from a plant and displays a change of the process data in a graph, a system diagram, a data list, or the like, based on the plant data. Event detection means for detecting that an event has occurred in the plant, automatic output screen processing for automatically displaying a screen after the event corresponding to each event, and automatic output screen storage means for storing an output screen, Event menu processing means for outputting a switching screen according to an event and accepting selection, an event corresponding switching screen storing means storing the switching screen, and an event corresponding switching screen processing for reading the switching screen from the event corresponding switching screen storing means Means and screen editing / display processing means for editing the automatic output screen and the switching screen and making a display request A display device on which an automatic output screen and a switching screen are displayed, and an input device for an operator to select an event menu. A switching screen when an event occurs is displayed by an event menu including menu contents corresponding to the event. It is configured as follows.

[0013]

The switching screen to be referred to when an event occurs is set in the switching screen registration table. When an event occurs, an event menu is output based on the switching screen registration table, and a request is waited for. Thus, when an event occurs, the switching screen can be output easily, so that the screen switching operation by the operator when the event occurs can be reduced.
