JPS6272009A - Formation of crt image plane - Google Patents

Abstract

PURPOSE:To form efficiently an image plane for monitor control over a plant by constituting image plane information which is already present so that it is optionally movable. CONSTITUTION:Coordinates of two points which indicate the range of a movement destination in a command input area 13 are displayed by selecting two points in an area 12 as an object of maintenance by typing or with a light pen. Then, the coordinate position of the movement destination is displayed by selecting one point in said area 12 by typing or with the light pen. Those coordinates in the command input area and while those coordinates are stored, an image on the screen of a CRT display device changes into an image after variation. When this screen image is satisfied, a command EXEC (execution) is inputted to erase the part specified as the movement destination. The image plane information and control information on the plant are copied and moved similarly.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a CRT screen creation method, and particularly to a CRT screen creation method for interactively creating a CRT screen for plant monitoring and control.

[Technical background of the invention]

FIG. 8 shows a general configuration of an electronic computer system that monitors and controls a plant using a CRT device as a man-machine interface.

First, as a monitoring function, in this type of system, information on each point of the plant 10 is saved in the database 7 via the plant information input section 8, and display information from this saved database is displayed via the CR7 display section 5. displayed on the CRT display 1. When displaying, the CR7 display section 5 refers to the screen data 4 and creates an image of the CRT screen to be displayed.

Next, control will be explained. Control light 2
The input axes (coordinates) are read through the CRT input unit 6, and what processing to perform on this input information is determined based on the screen data 4. The plant control unit 9 changes the state of the plant 10 based on this processing data.

This modified state of the plant may also be stored in the database 7. In addition, input information (setting values to the screen) from the key gate 3 is read through the CRT input section 6, and screen data 4 indicates where in the database 7 this information is to be saved.
The information is saved at a specified location in the database 7. Furthermore, the plant control unit 9 may change the state of the plant 10 based on this input information. Information regarding such supervisory control is closely linked to the screen display on the CRT, and maintaining the screen also includes maintaining this supervisory control information. FIG. 9 shows a conventional method for creating a CRT screen.

As shown in FIG. 9, when creating and changing a CRT screen in an interactive manner, the fixed screen data 4 in the screen data 4
1. Variable screen data (for display) 42. Variable screen data (
input) 43 and write 4 processing data 44, respectively.
I was deleting them one by one using LightSyn and Keygate, and then adding them again.

[Problems with background technology]

According to the above-mentioned conventional method, since it involves deleting and adding data one by one in the screen data, it has the disadvantage of poor screen creation efficiency.

[Purpose of the invention]

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an interactive CRT screen creation method with high screen creation efficiency.

[Summary of the invention]

In the present invention, existing screen information, such as plant information and control information for controlling the plant, can be moved or copied interactively within the same screen or between separate screens. be.

[Embodiments of the invention]

Examples will be described below with reference to the drawings. FIG. 1 is a block diagram of an embodiment for explaining the CRT screen creation method according to the present invention. In FIG. 1, the same parts as in FIG. 9 are designated by the same reference numerals, and their explanation will be omitted.

Reference numeral 11-1 is a screen changing unit, which changes screen data at a specified location within the screen data 4, that is, fixed screen data 41 at the same coordinates, variable screen data (for display) 42, and variable screen data (for input). 43 and light pen processing data 44 can be copied or moved to another location on the screen all at once or individually.

FIG. 2 is a state diagram illustrating the copying operation by the screen changing unit, and FIG. 3 is a flowchart showing the processing contents of the screen changing unit in correspondence with the operations shown in FIG.

As shown in FIG. 2(, ), a maintenance area 12 on the CRT display and a command input canister 13 are shown, and two coordinates (xt+) indicating the range of the copy source with respect to the command input canister 13 are shown. Type 'tL(xx, yt). Or two points on the area to be maintained 12 (
By selecting xle yt ) and (xteyt) with the light 4 button, their coordinates are displayed on the command input canister 13 (step 31 in FIG. 3). Then the second
As shown in Figure (b), the copy destination coordinate position (X3 +
ys) into the command input canister 13. Or one point on maintenance area 12 (x3+ys)
command area 1 by selecting with the light pen.
3 displays its coordinates. The coordinates of these command input canisters are input, and at the same time as the coordinates are stored, the image on the screen of the CRT display 1 changes to the changed image, as shown in FIG. 2(b).

That is, it is executed virtually on the screen (step 32).
. If this screen image is satisfactory, rz
By inputting the c (execute) command, the part specified as the copy source is newly created at the position specified as the copy destination as shown in FIG. 2 (C1) (step 33.3).
4). Furthermore, if the screen displayed during virtual execution is not satisfactory, screen creation can be canceled by inputting a CAM (cancel) command. At this time, as shown in FIG. 2 (C2), the image on the screen is returned to the state before copying (step 35).

The above is the operation regarding copying. Next, moving the screen will be explained.

Figure 4 is a state diagram explaining the movement of the screen;
The figure is a flowchart showing the processing contents of the screen changing unit in correspondence with the operations shown in FIG. 4 and 5, the operation of inputting the coordinate range of the movement source, inputting the coordinates of the movement destination, virtually executing it on the screen, and further determining whether or not the result is satisfied ( Figure 4(a),
(b) ) is the same as in the case of copying FIG. 2 described above. In other words, the portion that was "copying" in FIGS. 2 and 3 has simply become "movement." The difference between the case of movement in Figure 4 and the case of copying in Figure 2 is that when satisfied with virtual execution, the original data is left in the case of copying, whereas in the case of movement, This is the point at which the original data has been erased (FIG. 4(C), FIG. 5, step 54).

The case where a part of the screen data or the control information in the variable screen data and line processing data is changed after copying or moving is the same as in the conventional example shown in FIG.

In the above embodiment, copying and movement of screen information have been explained, but plant control information can also be copied and moved in the same manner as in the above embodiment.
It is possible to realize an interactive CRT screen creation method that is movable and highly efficient in creating CRT screens for plant control.

FIG. 6 is a block diagram of another embodiment according to the present invention. In this embodiment, a certain pattern on a certain screen is to be copied or moved across different screens. In FIG. 6, the same parts as in FIG. 9 are designated by the same reference numerals, and the explanation thereof will be omitted.

In FIG. 6, 4-2 is other screen data, and 11
-2 is a screen changing section. The structure of the square is the same as that in Figure 1. In the case of this embodiment, it goes without saying that the coordinates of the copy source, move source, copy destination, and move destination are input;
Specify the information (screen number) that specifies the destination.

FIG. 7 is a flowchart of the processing contents of the embodiment shown in FIG. In Stella 7'71, the copy source and movement source screen numbers are specified, and in step 72, the copy source and movement source screens are displayed. In step 73, the original coordinate range is input, and in step 74, the copy or movement destination screen is specified. Next, in step 75, the destination for copying and moving is displayed on the screen, and in step 76, the coordinates of the destination for copying and moving are input and executed virtually on the screen. The subsequent steps are similar to those in the above embodiment.

In this embodiment as well, an interactive CRT screen creation method with high CRT screen creation efficiency can be realized.

〔Effect of the invention〕

As explained above, according to the present invention, existing screen information is configured to be movable arbitrarily, thereby providing a CRT screen creation method that can efficiently create screens for monitoring and controlling a plant. can.
