(Function) By setting up the above table and making it possible to synthesize and display the process quantities input from the plant, information on the desired plant equipment can be obtained on the CRT display that is constantly used for plant operation. , operators' ability to respond to plant equipment abnormalities will be improved. Furthermore, maintenance can be performed using information obtained from the CRT display without having to look at documents such as drawings.

(Embodiments) Hereinafter, five embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 shows a CRT according to an embodiment of the present invention.
It shows the operation setup.

In the drawings, the same parts and corresponding parts as in FIG. 7 are given the same reference numerals.

In this embodiment, as shown in FIG.
Floor, 2nd floor, 3rd floor...and the west and east sides.

When creating layout drawing data, it is ideal to store the south side, north side, etc. divided according to the capacity that can be expressed on one screen, and to replace the plant as it is with the screen data, but if it becomes complicated, use f@abbreviation. Create a layout drawing. Also, when dividing the screen (for example, when dividing the first floor into four areas), information about which area is being displayed is included in both sides.

As shown in FIG. 3, the plant equipment information table 2g has one screen per plant equipment, and can be freely created on both sides in the same way as a graphic screen.

In this embodiment, information necessary for maintenance (repair) of the plant equipment, such as the circuit diagram of the plant equipment, operating conditions, and ratings, is displayed on both sides. The plant equipment information table 2g can be searched using the equipment number usually attached to plant equipment.

The display control processing section 2d performs different processes depending on requests from the input processing section 2e as follows. FIG. 4 shows processing flowcharts 1 to 1 of the display control processing section 2d.

If the request is a request to display a plant equipment operation screen (judgment 1), the requested screen data is retrieved from the double-sided data table 2b, and the process amount to be inserted and displayed on the screen is retrieved from the process amount data table 2c and sent to the output device 3a. Displays both sides for plant equipment operation. (Processing 1) If the request is a request to display a list of abnormal plant equipment (judgment 1), plant equipment abnormality information is extracted from the process amount data table 2C and displayed as a list on the output device 3i+. (Processing 2) If the request is a plant layout drawing display request (size Di), screen data is retrieved from the layout drawing data table 2f, and plant equipment abnormality information is retrieved from the process sewing data table 2C, and the plant equipment is determined to be normal. Abnormal items are displayed in different colors on the output device 3a. (Processing 3) If the request is a plant equipment detailed information display request (judgment 1), screen data is extracted from the plant equipment information data table 2g based on the equipment number input by the operator, and the process amount related to the screen display is added to the process from the data table 2c.
