Abstract

PURPOSE:To eliminate a data input error and rule out a data reinput process by automatically updating necessary data only with change of display position of symbols on a skeleton display screen. CONSTITUTION:A facility symbol which is moved through a man-machine interface is selected on a skeleton display screen to designate a new display position (S1). A pixel display position slot data of instance data of the moved symbol is changed (S2). A data element including instance of the moved symbol is searched from connecting lines to obtain a connecting line information of the moved symbol (S3). With this information, a connecting line is redrawn depending on a program and a connecting line data is updated automatically (S4) and a symbol of grounding, etc., is automatically moved the desired position on the updated connecting line (S5). A connecting line coordinate slot data of a connector instance is automatically updated by a program on the basis of the searched ground line information (S6).

2. Description of the Related Art As a conventional data input method for a power system supervisory control system, for example, Japanese Patent Application No. 1-131760 (data input method for a power system supervisory control system), a transformer that realizes equipment and device data maintenance functions. There is an automatic procedure table generation system. With this system, when adding, deleting, or changing equipment data, the symbol display position on the skeleton (single line connection diagram) and other data are simultaneously maintained, and the display position of the equipment symbol drawn on the skeleton is moved. In this case, the data regarding the moving symbol will be input again after being deleted via the man-machine interface.

10 and 11 are flow charts for changing the symbol display position in the conventional method. 12 to 31 show the relationship between the internal data of each frame and the skeleton. FIGS. 12 to 15 are states before symbol deletion, FIGS. 16 to 19 are states in which the transformer main 2B is deleted,
20 to 23 show a state in which the symbol display position is changed by re-inputting the data of the main 2B, FIGS. 24 to 27 show a state in which the connecting line is drawn and the ground data is re-input, and FIGS.
Reference numeral 1 shows the state after data expansion.

First, when a pixel is drawn on a skeleton diagram as shown in FIG. 15A, a new instance frame is generated under the class associated with the pixel as shown in FIG.
Details of each instance frame at this time are as shown in FIGS. 13 and 14. In FIG. 13 and FIG. 14, the part surrounded by the slot value frame and the connector data (connection 10-
01) is generated by expanding the data. Further, in FIG. 15, the connection lines on the skeleton and the connection line data have a one-to-one correspondence, and the second parameter represents “data expanded / unexpanded” (t / nil).

In order to change the display position of the transformer main 2B symbol, first, (1) the equipment symbol for which the display position is to be changed is selected from the skeleton via the man-machine interface, and the equipment symbol and its attribute data are selected. delete.

(2) If a connection line is drawn on the equipment symbol for changing the display position, the connection line is also deleted from the skeleton.

(3) Also, the corresponding connection line data is deleted.

(4) If a symbol such as ground is connected to the deleted connection line, the symbol such as ground is also deleted from the skeleton.

(5) If the moving facility device constitutes a connector, the second element of the connection line data forming the same connector as the deleted connection line is nil as shown in FIG.
Set to (nothing; nothing, zero).

(6) Delete the data of the connector. Figure 1
2. If the connection 10-01 instance in FIG. 14 is deleted, the result becomes as shown in FIGS.

(7) After that, the data generated by tracing the connection line (slot value surrounded by the frame in each instance frame of FIGS. 13 and 14) is deleted. The results are shown in FIGS. 17 and 18.

(8) A new display position of the equipment symbol is specified through the man-machine interface and attribute data is reentered. This state is shown in FIGS.

(9) If the connection line is drawn on the equipment symbol before the display position is changed, the connection line is drawn through the man-machine interface. In FIG. 27, it can be seen that the connection line data in the system is updated by drawing the connection line.

(10) If the equipment device symbol before the display position is changed has a connecting line drawn, and data expansion is performed, data obtained from the connector data and the connection relationship (in FIGS. 25 and 26, If the slot value enclosed in the frame) has been generated, a switch for data expansion is selected on the man-machine interface, and these data are automatically generated by the program. 28 to 31 show a state after the data is expanded.

[0015]

However, as shown in FIGS.
In the conventional method shown in FIG. 31, in order to change the display position of the equipment symbol via the man-machine interface, all the data relating to the moving equipment symbol is deleted and then the data is input again via the man-machine interface. become. For example, when changing the display positions of the transformer and the main 2B symbol, only the data of A shown below should be changed, but in the conventional method, the data of B shown below must be deleted and then input again.

A-Transformer-01: Name display position: Pixel display position-Contact 10-01: Connection line coordinates-Grounding-01: Name display position: Pixel display position-Data relating to Transformer-01 among connection line data B-LS-01: Connector: Affiliated Equipment-LS-02: Connector-Transformer Instance Transformer-01: Affiliated Equipment-Ground Instance Ground-01-CB-01: Connector-Connector Instance Connection 10-01 ： Affiliated equipment ・ Bus-01: Non-affiliated connector ・ Data related to Transformer-01 in connection line data: Adjacent equipment ・ Bus-02: Non-affiliated connector: Adjacent equipment Transformer instance, grounding instance, connection line data Re-input via the man-machine interface, but other data is automatically selected by selecting the data expansion item on the man-machine interface. It is made.

Therefore, the following problems occur. (1) A great amount of work time is required. (2) A data input error may occur. (3) The same work must be repeated, which is very troublesome.

The present invention has been made in view of the above points, and an object thereof is to easily change the display position of a symbol without the work of deleting an instance of equipment or equipment and re-inputting data. An object of the present invention is to provide a skeleton maintenance method for a power system supervisory control system.

[0019]

The present invention provides a function for securing a data storage area and newly setting data when a facility equipment frame including skeleton data and a facility equipment symbol is newly added to a skeleton screen in an expert system construction support tool. And a function for releasing a data storage area when the symbol is deleted, and a connector creation production rule for automatically creating connector data indicating a connection relationship of various equipment, in the power system monitoring and control system, the expert construction When the display position of the display symbol with the connecting line drawn on the skeleton screen is moved to the support tool, a new connecting line is drawn for the symbol and the pixel display position slot in the equipment frame is displayed. Symbol coordinate update function to update data, and the automatically created connector And connectors data update function provided for updating the connection line coordinate slot data in the frame data,
By selecting the display symbol on the skeleton screen and moving the display position to the desired position, the data is automatically updated by the symbol coordinate updating function and the connector data updating function, and the connecting line showing the connection relationship. The feature is that the data is updated automatically as well.

[0020]

[Operation] When the operator moves the symbol display position on the skeleton screen through the man-machine interface,
When a connection line is drawn on the symbol, the man-machine interface draws a new connection line so that the connection relationship does not change for the moved symbol, changes the pixel display position slot data of the symbol, and relates to the symbol. The connection line data and the connection line coordinate data in the connector data are automatically changed. Therefore, the display position of the symbol can be changed without once deleting the data relating to the moving symbol and inputting the same data again.

Further, even if the equipment of the moving symbol has the connector data, the connection relationship does not change, so that only the connection line coordinate slot data of the connector data needs to be changed.

As described above, the necessary data is automatically updated only by changing the display position of the symbol on the skeleton screen, so that the data input error is eliminated and the data re-input process is not necessary, and the work is simplified. Be converted.
