There is an automatic generation system for local procedure tables. This system adopts a method of simultaneously maintaining a symbol display position in a skeleton (single line connection diagram) and other data when adding, deleting, or changing equipment data.

[0003]

However, in the above-mentioned conventional method, the display position of the equipment symbol drawn on the skeleton is changed through the man-machine interface, or the data is moved in order to copy or move the data. After deleting all the data relating to the equipment symbol, the data is re-entered via the man-machine interface. For this reason, on the skeleton screen, it is impossible to copy and move (screen edit) screen data including a plurality of symbols including their connection relations, and there is a problem that the efficiency of data creation is low.

[0004] The present invention has been made in view of the above points, and an object of the present invention is to provide an electric power capable of automatically copying and moving equipment and device data on a skeleton screen in a form including connection relationships. An object of the present invention is to provide a frame data editing method for a system monitoring and control system.

[0005]

SUMMARY OF THE INVENTION The present invention provides an expert system construction support tool with a facility equipment frame including skeleton data and a function of securing a data storage area and newly setting data when a facility equipment symbol is newly added to a skeleton screen. And a function for releasing a data storage area when deleting the symbol, and a connector creation production rule for automatically creating connector data indicating a connection relationship between various types of equipment. , Slot items for defining attributes in each class include type slots, display coordinate slots,
A display coordinate calculation function for calculating the display coordinates of the moving destination and storing the calculated coordinates in the display coordinate slot, and a slot value and a copy of the copy source frame in the expert construction support tool. A copy function is provided to automatically copy the slot value of the previous frame that has the same slot value, a frame name is created for each symbol on the skeleton screen, a frame data list is created, and a work area for each frame data is created. Each slot name after copying is stored in the slot, and each frame name of the copy destination is changed to the same frame name as the slot name stored in the work area slot of the copy source, and the copy function is executed on the skeleton screen by the copy function. After executing the copy of each frame data, The work area slot is and returning to the initial value.

[0006]

[Operation] By copying on the skeleton screen, a new instance is created without duplicating the instance name. Since there is a copy function for automatically copying a slot value in which the slot value of the copy source frame is the same as the slot value of the copy destination frame, duplication of data input can be avoided. Further, equipment and device data can be automatically copied and moved on the skeleton screen in a form including the connection relationship.

[0007]

An embodiment of the present invention will be described below with reference to the drawings. In the present invention, a frame structure dedicated to screen editing is created for the purpose of a plurality of editing (moving, copying etc) in a form including their connection relations, instead of treating individual symbols on the screen as a single unit. .

First, the following functions and functions are described in Japanese Patent Application No. Hei.
It is the same as that described in 1760. a. The frame structure (M
(a knowledge expression method based on the frame theory of insky) is applied to the data system.

B. Simultaneous input of single-line diagram (skeleton) data and attribute data of equipment, devices, switches, relays, and fault indicators.

C. When the display symbol of the skeleton screen is selected on the display symbol list, the system automatically secures the data storage area of the equipment, device, and switch (creates an instance frame).

D. When the display symbol of the skeleton screen is deleted from the skeleton screen, the data storage area of equipment, devices, and switches is released (instance frame is deleted)
Is performed automatically by the system. The creation of the instance frame is performed by a commonly used expert system construction support tool.
The release function is provided by the tool.

E. The connection relation (connector) data of the equipment and the switch is automatically created by a development program from the connection line data indicating the connection relation of the equipment and the equipment, which is automatically generated when a single-line diagram (skeleton) is created. In other words, a human draws equipment, equipment, and connection lines in a skeleton diagram creation CAD, and the connection state of the equipment and equipment is stored in the system as connection line data, and the system automatically creates connector data according to production rules. Is what you do.

Further, according to the present invention, the expert construction support tool calculates a display coordinate of a movement destination and stores it in the display coordinate slot, a slot value of a copy source frame and a display coordinate calculation function of the copy destination frame. A copy function is provided for automatically copying a slot value having the same slot value.

Next, a process of copying the screen data composed of the four symbols shown in FIG. 2 and adding it to the frame structure while copying the connection relation thereof will be described with reference to the flowchart of FIG.

(1) First, the four types of symbols shown in FIG.
An instance frame is created as shown in FIGS. 3A to 3D by assigning frame names MAD to (securing a data storage area). In this case, the following four slot items are set for each frame. 1. Type Type of symbol 2. 2. Display coordinates Display coordinates on the screen. 3. Connection relationship List of adjacent symbols Work area.

(2) Create a copy source frame data list as follows (step S ₁ ). (SYM-A SYM-B SYM-C SYM-D) Work is performed based on this list.

(3) The copied slot name is stored in the work area slot of each frame data as follows (step S ₂ ). SYM-A work area: SYM-E SYM-B work area: SYM-F SYM-C work area: SYM-G SYM-D work area: SYM-H.

(4) A copy of each frame is created with a different frame name (steps S ₃ and S ₄ ). However, only the type slot and the connection relationship slot are copied as they are, and the display coordinate slot is calculated and stored based on the previously obtained relative coordinates. For example, a case where SYM-A is copied as SYM-E is shown in FIG. In the connection-related slots, the work slot value of SYM-B is SYM-F.
Therefore, the connection relation slot of the copy destination is (SYM-F)
Becomes Similarly, when copying SYM-B to SYM-H as SYM-F to H, respectively, it is shown as in FIGS.

(5) Finally, copy source (SYM-A to D)
NIL (zero, no) the work area slots in the copy back is completed (Step S _5).

[0020]

As described above, according to the present invention, a display coordinate calculation function and a copy function are provided in the expert construction support tool, and a frame data list is created by giving a frame name to each symbol on the skeleton screen. Then, each of the copied slot names is stored in the work area slot of each frame data, and each copy destination frame name is changed to the same frame name as the slot name stored in the copy source work area slot, and the skeleton is changed. After each frame data is copied on the screen by the copy function, the work area slot of the copy source frame data is returned to the initial value, so that the following excellent effects can be obtained.

(1) By realizing copying on the skeleton screen, a new instance can be created without duplicating the instance name.

(2) Duplicate data inputs are avoided because the same slot value is automatically copied.

(3) The display coordinates on the screen are automatically calculated and input based on the relative coordinates.

(4) A plurality of edits (movements, copies, etc.) including the connection relationship can be performed.

(5) Since the step of re-inputting data is eliminated, it is not necessary to repeat the same work, and the work process is remarkably shortened.
