DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram showing one embodiment of the present invention. In the figure, a control unit 1 monitors and controls a plant 2. Then, the control unit 1 displays various screens on the display unit (CRT) 4 based on the drawing data stored in the storage unit 3 based on the monitoring result. The operation unit 5 operates the control unit 1 with a keyboard or a mouse, for example.

The control section 1 comprises a monitoring control means 11 and a display processing means 12. The control unit 1 is generally formed of a computer, and includes a monitoring control unit 11 and a display processing unit 1.
2 is generally described in a program. This program is generally stored on a recording medium (FDD, CD-RO).
M) is installed on the computer.

The monitoring control means 11 monitors the plant 2 and controls the plant 2.

The display processing means 12 receives the monitoring result from the monitoring control means 11, calls the drawing data determined based on the scaling instruction from the storage unit 3, calculates the size, and displays the instrument figure on the display unit. 4 is displayed. The display processing means 12 also performs display processing of various screens.

The operation of such a device will be described below.
FIG. 2 is a flowchart showing the operation of the apparatus shown in FIG. FIG. 3 is a diagram showing a drawing data comparison table of the apparatus of FIG. This drawing data comparison table is stored in the storage unit 3.

The operation unit 5 displays the type or size of the instrument diagram or the change or advance designation of the instrument diagram.
To do. The display processing means 12 determines whether or not the instrument diagram display has a compact size (S1).

When the size is the compact size, it is determined whether or not the window is an SL (Scale Large) window based on a drawing data comparison table of the scale of the instrument diagram created corresponding to the window size (S2). In the case of the SL window, the drawing data of the SL window of the compact instrument diagram is collected from the storage unit 3 based on the bitmap and the font of the drawing data comparison table (S3). If it is not the SL window, the drawing data of the SM (Scale Mini) window of the compact instrument diagram is collected from the storage unit 3 based on the bitmap and the font of the drawing data comparison table (S4).

If the size is not the compact size, it is determined whether or not the window is the SL window based on the drawing data comparison table of the scale of the instrument diagram created corresponding to the window size (S5). In the case of the SL window, the drawing data of the SL window of the normal instrument diagram is collected from the storage unit 3 based on the bitmap and the font of the drawing data comparison table (S6). If it is not the SL window, the drawing data of the SM window of the normal instrument diagram is collected from the storage unit 3 based on the bitmap and the font of the drawing data comparison table (S7).

After the drawing data is collected, the scale is calculated based on the horizontal width, for example, with the vertical and horizontal ratios of the instrument diagram fixed (S8). That is, the calculation of (length after calculation) = ((length before calculation) × (width at the time of calling the instrument diagram)) ÷ (width of the instrument diagram reference) is performed.

Each part is drawn on the display unit 4 using the drawing data and the scale calculation (S9). Monitoring control means 1
The display processing means 12 changes the drawing (for example, a numerical value or a scale bar) of the instrument diagram according to the monitoring result by the step 1.

Here, the types of the SL window and the SM window are provided, because the design is slightly changed depending on the window size. The SL window is designed based on a window size of 1024 × 768 dots, and the SM window is designed based on a window size of 640 × 480 dots. The difference in the design of this window will be described with reference to FIG. a is the instrument diagram of the SM window, and b is the instrument diagram of the SL window. The difference between the windows is that the instrument diagram b has horizontal lines b1 to b3, but the instrument diagram a has only the horizontal line a1. Although it is a bitmap,
The display processing means 12 calls up the arrow A and the like having the size shown in the drawing data comparison table as the drawing data from the storage unit 3 and displays it on the display unit 4.

Next, the operation of the present invention will be described using a specific example. For example, if the window size is 1600 × 120
If it is between 0 dots and 1280 × 1024 dots, the SL window is selected for the design from the drawing data comparison table, the bitmap is 24 × 24 dots, and the font size is scaled according to the size based on 20. You. Drawing data based on this information is collected. Then, the scale calculation is performed, and the drawing is performed on the display unit 4.

FIG. 4 shows a display example of a graphic window. In the figure, a is a normal instrument diagram, and b is a compact instrument diagram. The compact instrument diagram b is designed to be half the vertical width of the normal instrument diagram a, and the tag comment a1 and the digital value (PV (process value), SV
(Set value), MV (operation value)) a2 and the entry zone call button a3 are eliminated. Thereby, in the compact instrument diagram b, the status display portion is emphasized for the purpose of monitoring.

As described above, since the display processing means 12 calls the drawing data in accordance with the scaling, the size of the instrument diagram can be changed.

Further, since the instrument diagram can be arranged at any position and size, the instrument diagram can be used as a general-purpose part on the graphic window, so that engineering suitable for the user can be performed.

Then, a font or a bitmap is selected according to the scaling, so that the drawing is not distorted. That is, the drawing of the instrument diagram does not collapse.

Further, since the aspect ratio of the size of the instrument diagram is fixed, the drawing of the instrument diagram can be displayed with a fixed design. That is, since the design is constant, it is easy to recognize even if the size is changed.

In addition, since a compact instrument diagram is provided, the instrument can be monitored without taking up space. In addition, since it can be provided in a graphic window or the like without taking up space, important instruments can be monitored. Then, it is possible to respond to the recent demand for displaying a plurality of screens.

The present invention is not limited to this, but may be as follows. The configuration in which the drawing data comparison table is stored in the storage unit 3 has been described.
A built-in configuration may be used.

[0030]

According to the present invention, the following effects can be obtained. According to claims 1 and 4 , corresponding to the scaling,
Since the drawing data is called, the size of the instrument diagram can be changed. In addition, since the instrument diagram can be arranged at any position and size, the instrument diagram can be used as a general-purpose component on the graphic window, so that engineering that meets the user's preference can be performed.

Claims 1, 4 According to the scaling,
Since the font or bitmap is selected, the drawing does not collapse. That is, the drawing of the instrument diagram does not collapse.

According to the second and fifth aspects , the vertical and horizontal ratio of the size of the instrument diagram is fixed, so that the drawing of the instrument diagram can be displayed with a fixed design. That is, since the design is constant, it is easy to recognize even if the size is changed.

According to the third and sixth aspects of the present invention , since a compact instrument diagram is provided, the instrument can be monitored without taking up space.

According to the first and fourth aspects, since the size of the instrument diagram can be freely set, the instrument diagram can be provided in a graphic window or the like, and important instrument diagrams can be monitored. In addition, it is possible to respond to recent demands for displaying a plurality of screens.
