Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable screen display control method for displaying variable data that fluctuates in real time on a display screen in a display format corresponding to the screen display format of the variable data, and more particularly, to fluctuation of variable data. The present invention relates to a variable screen display control method for reducing the burden of the programmer's labor due to an increase in the program capacity due to the above, and for displaying the display screen quickly.

[0002]

2. Description of the Related Art In general, computer processing methods include
There is a real-time processing method in which data is processed as soon as it is generated. When controlling the temperature of the controlled object of the process in the real-time processing method, for example, the latest measured temperature is input in real time, displayed on the CRT in the control room, and the process control is performed. In the above process control, since variable data of the temperature that fluctuates in real time is input, the temperature parameter of the variable data is displayed in various display formats such as numerical values and graphs. In the system for displaying the above display format by a program, all the temperatures of the input variable measured data are sequentially converted into the display format by the program and displayed on the CRT, which increases the amount of work of the programmer. It was

Further, when the temperature of the controlled object changes in real time, it is necessary to add a program, and the execution environment of the program is limited as the program capacity increases.

[0004]

However, conventionally, since the program is added or changed every time the temperature of the controlled object changes, the labor required for the addition work increases and the burden on the programmer increases. There was a problem to do. Further, as the number of programs increases, the program capacity also increases, which limits the execution environment of the programs and delays the screen display processing, which causes a problem of a decrease in the processing capacity of the system.

The present invention has been made in view of the above-described conventional problems, and an object thereof is to reduce the burden on the programmer due to the increase in the program capacity due to the change of the variable data and to reduce the display screen. The object of the present invention is to provide a variable screen display control method for preventing a decrease in the processing capacity of the system by displaying the prompt.

[0006]

To achieve the above object, according to the claim correspondence diagram shown in FIG. 1, the present invention provides a fixed data registration table 1 for registering fixed data on a display screen.
And a variable data registration table 3 for registering variable data corresponding to the screen display format of variable data that fluctuates in real time, and fixed data for registering fixed data registered in the fixed data registration table in a fixed data display memory. Screen display means 5, variable screen display means 7 for interpreting the screen display format of the variable data and setting the variable data registered in the variable data registration table in the variable data display memory, and the variable screen display means. The gist is that the variable data display memory set by means of and the fixed data display memory set by the fixed screen display means are overlapped and displayed on the display screen.

[0007]

With the above arrangement, the fixed screen display means 5 sets the fixed data registered in the fixed data registration table 1 in the fixed data display memory. Next, the variable data that changes in real time is registered in the variable data registration table 3 in correspondence with the screen display format of the variable data. When displaying on the CRT, the variable data registered in the variable data registration table 3 by the variable screen display means 7 interprets the screen display format of the variable data and sets it in the variable data display memory to set the variable data. Since the display memory and the fixed data display memory are overlapped and displayed on the display screen, it is possible to reduce the labor burden on the programmer due to the increase in the program capacity due to the change in the variable data.

[0008]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 2 shows the variable screen display control system of the present invention.
For example, it is a diagram showing a fixed data registration table 1 and a variable data registration table 3 showing an embodiment when applied to process control.

The fixed data registration table 1 is stored at a predetermined address of a memory (not shown), and has a title "display of variable data", a subtitle "number", a "state", a "number" and a "graph". Characters of fixed data are stored at a predetermined address.

The variable data registration table 3 is stored at a predetermined address of a memory (not shown), and for example, an integer area 11 having an integer 1 to an integer 7 indicating a measurement point of a controlled object of the process, and the measurement concerned. The character string area 13 having the character strings 1 to 7 indicating the state of the controlled object at the point. Further, the variable data registration table 3 has a coordinate value X1 for displaying the control state of the process in a graph,
The coordinate value area 15 having Y1 to X1 and Y5 is provided. The integers 1 to 7, the character strings 1 to 7 and the coordinate values X1, Y1 to X5, and Y5 are registered, for example, in the order of the smallest X coordinate of the coordinate values. Here, the integer 1 to
5, character strings 1 to 5 and coordinate values X1, Y1 to X1, Y5
Of these, for example, when changing the integer 2 and the integer 4,
The integer 2, character string 2 and coordinate values X2, Y2 and the integer 4, character string 4 and coordinate values X4, Y4 are exchanged. Also,
When a change occurs in the state of the integer 3 among the states that fluctuate in real time, the controlled object can be changed to the latest state simply by changing the character string 3 to the changed state.

Next, the screen format will be described using the screen layout 17 of FIG. 3 and the display memory of FIG.

The screen format 17 is displayed on a CRT (not shown). The title "display variable data" is shown in the upper part of the figure, the subtitle "number" is shown at the upper left end of the figure, and the subtitle "state" is adjacent to the number. Further, the character 19 of fixed data of "graph" is arranged at the substantially central portion in the drawing. The title "display of variable data" and the like are set in the fixed data display memory 27 by the program.

The "number" of the character 19 of the fixed data is
It is displayed by the variable format "99" for the variable data numerical value, and the information indicated by this format is displayed as a 2-digit numerical value without zero suppression and according to the size of the drawn font. The "state" is displayed by a character variable format "XXXX", and the information indicated by this format is displayed by a full-width character string of four characters. In the "graph", five lines in the line graph format are displayed. Numeric variable format "99" of the variable data, character variable format "XXXX"
And the five line lines in the line graph format are set in the variable data display memory 29 by the program.

When the screen layout 17 is displayed on a CRT (not shown), the program executes a logical sum process (superposition process) on the fixed data display memory 27 and the variable data display memory 29 to display screen memory 31. Set to.

Next, the operation of this embodiment will be described with reference to the flowchart of FIG.

First, when the system starts up, the program decodes the variable data registration table 1 stored at a predetermined address of a memory (not shown) by the screen interpreter. After decoding, the program asks the user whether or not the display request is the first time, and if it is the first time, the character 19 of the fixed data shown in FIG. 3 is set in the fixed data display memory 27, and if it is not the first time, the process proceeds to step 120 ( Steps 100-110).

In step 120, the program ends the process if the count value indicating the number of processes indicates the completion of the process. On the other hand, when the process is not completed, the program interprets the numeric format and sets the numeric character string in the variable data display memory 29 when the variable data is a numeric value (steps 120 to 140). If the variable data is a character, the program interprets the character format and sets it in the variable data display memory 29 according to the designated font (step 150). If the variable data is a graph, the program interprets the format of the graph, sets the broken line in the variable data display memory 29, and proceeds to step 17
Go to 0 (step 160).

When the program proceeds to step 170, the program counts up the number of processes and returns to step 120 (step 170).

Thus, even if the variable data fluctuates, it is possible to reduce the work such as adding a program as in the conventional case and prevent the programmer from increasing the work amount. Further, the display screen can be displayed quickly by reducing the work such as adding a program.

[0021]

As described above, according to the present invention, the variable data is registered in the variable data registration table in correspondence with the screen display format of the variable data that fluctuates in real time, and the variable data is displayed on the display screen. As the program capacity increases due to the change of the variable data, the burden on the programmer is reduced, and the display screen is displayed quickly, so that it is possible to prevent the deterioration of the processing capacity of the system.
