Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display processing method for displaying, on a monitoring control screen, a display symbol or the like changed according to a change in the state of equipment or equipment in a monitoring control system.

[0002]

2. Description of the Related Art In a supervisory control system, a display symbol determination algorithm (program) as shown in FIG. 8 is prepared for displaying a supervisory control screen as shown in FIG.
In this algorithm, display data and attribute data types specific to equipment and devices are described, and when a screen display is requested, the status and numerical values of each dynamically changing equipment and device are periodically updated. The data (character strings and graphics) is displayed on the screen according to the acquired data. At that time, in order to perform processing at high speed, processing is distributed for each function.

In another method, as shown in FIG. 9, a display algorithm (program) describes an attribute data access function (a current state acquisition function or an abnormal state acquisition function) of a facility or a device to display a screen. Display is realized.

[0004]

According to the conventional method, when a bug (unintended phenomenon) occurs, it takes a very long time to identify the cause. Further, every time a specification is changed or applied to another system, a great deal of labor is required to correct and change data and attribute data access functions scattered in the algorithm without omission. Also,
It was difficult to improve the development efficiency because the operation verification required about the same time as the first development.

SUMMARY OF THE INVENTION An object of the present invention is to provide a display processing method of a versatile monitoring control screen which makes it easy to identify the cause of a bug or change a specification and can be applied to another system.

[0006]

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION

(First Embodiment) FIG. 1 shows an object and display symbol determination algorithm according to an embodiment of the present invention.
The object OBJ is prepared for each facility / equipment to be monitored, and has attribute data of the equipment / equipment such as an equipment name and data relating to display such as symbol information.

FIG. 2 shows the relationship between the display symbols described in the object OBJ and the object data. The object data has attribute data such as “part name” and “equipment name” and data related to display such as “display position” and “display condition”.

The actual processing based on the object data is as shown in FIG. 1. The equipment data collection processing and whether the current state of the equipment whose data has been collected is "ON" or "OFF" is determined. If the status is neither ON nor OFF, the "abnormal state is ON" or the "abnormal state is OF
F ", and one of the symbols 1 to 4 is selected and displayed on the screen. In addition, "N
When it becomes "O", a fixed symbol is selected and displayed on the screen.

[0013] Therefore, since the object is in charge of the processing for the actual display, the processing of the display algorithm only requires the display of each object. This allows
Even when a bug occurs, the object can be easily specified, and the correction work can be performed efficiently.

[0014] In addition, when the specification is changed or applied to another system, the modification / editing of the object is mainly performed, and the modification / change of the algorithm itself can be minimized.

For example, FIG. 3 shows an example of adding a display symbol and correcting an object, in which a symbol “△” is added, and the symbols displayed on the object data side are changed according to display conditions 3 and 4. The internal processing of the object due to this specification change is as shown in FIG. 4, and the algorithm itself does not need to be modified or changed.

Although the case where a display symbol is used as a display component is shown, the same processing method can be applied to other display components.

(Second Embodiment) The present embodiment is applied to a method of changing the display of a display component by changing the screen display by using an attribute data access function of equipment or equipment.

FIG. 5 exemplifies the conversion of the attribute data held by each facility / equipment into an ID and a tabulation of an access function, and sorts “attribute ID” and “data acquisition function” or “change inquiry function” for each attribute data. Keep it.

On the other hand, an attribute data access function is not directly described in the display symbol determination algorithm describing the change operation of the display component, and the attribute I of the attribute data to be referred to is not described.
Describe D. FIG. 6 exemplifies a display symbol determination algorithm, and access to attribute data is determined using a function table and an attribute ID.

In this way, when the attribute data to be referred to is changed, the attribute ID only needs to be changed instead of changing the access function itself as in the related art.

Further, when setting attribute data to be referred to when creating a display component, it is only necessary to refer to an attribute ID number prepared on the equipment side to be monitored and set. When the process of the display component is actually described, it is only necessary to call the function table using the ID number. Therefore, even if the reference attribute data is changed, it is not necessary to change the description content of the program.

From the above, it is possible to perform the process of creating the display component without any influence even if the monitoring control system to be processed is changed.
Greater versatility.

[0023]

As described above, according to the present invention, an object prepared for each facility / equipment to be monitored is provided with display-related data in addition to the equipment / equipment attribute data. The algorithm only requires the display of each object, and the object is in charge of the actual display processing, making it easy to identify the cause of bugs and flexibly changing specifications and applying to other systems. It becomes a versatile method that can be handled.

Further, according to the present invention, the attribute data access function held by each facility / equipment is tabulated,
Functions can be sorted by attribute ID number, and the display algorithm has an attribute ID that refers to the attribute data access function, so there is no need to change the access function to access the attribute data of equipment and devices Therefore, the display component creation process becomes highly versatile and does not depend on the system.
