Abstract

PURPOSE:To improve operability and maintenance by executing the processing of a changing part as a correlated data base structure using a logical operation formulas for display. CONSTITUTION:In the drawing display for a process, a drawing for monitoring and controlling a plant is designed, base data are formed in each fixed picture and variable picture by using display characters or the like and correlated data describing the correlation of equipment data 4 and status data 5 to the variable pictures are made base data by using the logical operation formulas for inputted to a processor PR through an input device 1. The processor PR forms both data 3a, 3b on the display screen and registers the data in a memory. If a change is generated in the plant status, the status data 5 are accumulated and processing for changing the displayed picture is executed 8 and displayed on a display device 7. The logical operation formula include OR or the like and process processing and the change and correction of its status display are executed on the basis of the combination of the operation formulas.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a display method for a display screen displayed on a display device connected to a data processing device.

[Prior art]

Conventionally, there has been a device of this type as shown in FIG.

In the figure, one data input device is connected to the processing device PR. In the processing device 2, a process of creating detailed data for a display screen using data from the input device 1;
is screen data stored in a memory (not shown), consisting of fixed data 3s"s variable data 3b of the display screen, data 3C indicating the figure of the macro parts used in the fixed part 3a and the variable part 8b. 4F!, Equipment data inputted from a plant (not shown) %5 is status data inputted from the plant and gives information on the status of the plant and its changes, 6 is used to change the screen when a status change occurs in the plant. Processing 7 is a display device connected to the processing device PR.

Next, the operation will be explained. Design screens for plant monitoring and control, and use single-color display characters, v-black graphic numbers, etc. as a basis for fixed and variable screens.

- Create a data file and input it to the processing device PR via the input device 1. In process 2, fixed part data 8 and variable part data 8b of the display screen are created and stored in the memory. In process 6, an initial screen for plant monitoring and control is displayed on the display device 1 using the fixed data 3m and variable data 8b. When a state change 5a occurs on the plant side and the change information 5 is accumulated, a process 6 examines the change information 5, correlates it with the equipment data 4, and then displays the screen on the display device 7. The display screen is changed by determining which part should be changed and how, and calling the variable data 3b.

Conventional process drawing display systems are configured as described above, so when displaying variable parts, equipment data and variable data variable numbers are assigned to each variable part on one display screen. Since it is necessary to perform graphical processing while making correspondences, the processing procedure becomes complicated, and there is also a drawback that it is necessary to change the display data and its processing procedure when changing the screen.

[Summary of the invention]

This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and it displays variable data as well as process change information and logical operation formulas of equipment data on the display screen, and uses this to display variable data on the display screen. It is an object of the present invention to provide a process drawing display method that can improve operability and maintainability by performing processing on the process drawings.

An embodiment of the present invention will be described below with reference to the drawings. Second
In the figure, the same parts as in Fig. 1 are denoted by the same symbols.s3e
3f is graphic data of macro parts, and 3f is related data of a logical operation formula, which has a function of linking variable data 3b with plant equipment data 4 and plant status data 5. 8
is a process for changing the display screen when the plant status changes. The related data 3f consists of a relay shift 3gs attribute 3b as shown in FIG.

Next, the operation will be explained. After designing screens for plant monitoring and control, display characters, colors.

Basic data is created on the fixed image and variable image sides using macro figure numbers, etc., and equipment data 4 and status data 5 are created.
The related data describing the relationship between the variable image and the variable image is converted into basic data using a logical operation formula, and is sent to the processing device PR via the input device 1.
Enter. In the processing device 2, the fixed data 3 on the display screen
A and variable data 8b are created and registered in the memory.

Related data 3f of change information 5 is also registered.

The initial screen display for plant monitoring and control is performed when a change occurs in the state of the plant while the fixed data 8a and the variable data 8b are being displayed on the display device 7 along with the graphic 8@ in the process 8.

Status data 5 is accumulated and processing 8 is executed.

This is the attribute of relation 8g displayed in related data 3f) 3h, regardless of the form of the state change.
is obtained by executing a series of logical expressions.

Process 6 is the item (attribute) of relation 3g
along with the state deterioration in the state data 5.

Using data such as plan) A in equipment data 4, calculate the calculation formula shown by translation 8g,
Based on the calculated value thus obtained, a possible number defined in another relation is obtained, and the display contents of the screen existing in the variable data 3b are created.

It is displayed on the display device 7.

This arithmetic expression includes logical sum, logical product, negation, addition, and subtraction, and the process processing and its status display are changed and corrected by the combination of these.

Further, in the above embodiment, the processing when there is a change in the state of the process has been described, but by applying the description of related data, the same effect can be achieved on the initial screen display and the form display.

〔Effect of the invention〕

As described above, according to the present invention, since the processing of the variable part is structured as a related database using logical operation expressions for display, there is no need to perform variable part display in case-by-case processing. This has the effect of making corrections easier.
