Abstract

PURPOSE:To remarkably shorten a time compared with a plotting method of interactive format without necessitating the generation of a layout on a picture by an operator, by executing the plotting from input data for plotting and a display rule automatically. CONSTITUTION:Firstly, after deciding the number of sections, a main line switch (a) is displayed at a position regulated by the display rule. Next, the section is decided whether it is a first section or not, and a rise cable is displayed when it is the first section, and the line of just preceding section is displayed when it is the section other than the first section. Next, the line of its own section is displayed, and after that, the mounting of a link switch (d) is decided. when it is mounted, it is displayed, then, the time (e) of its own section for link wiring is displayed. Afterwards, it is judged whether or not a link opponent exists, and the line (f) of a link opposite section is displayed when it exists. After that, an operation is returned to its original step, and a processing is completed after repeating the above processings for the number of times equivalent to the number of sections.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display (drawing) method for displaying a power distribution line on a CRT screen using a computer.

[Conventional technology]

Although the development of power distribution computer systems for controlling power distribution systems using computers has recently become active, the current situation is that a method for displaying power distribution system diagrams on a CRT screen has not been established. This means that the power distribution system has to add and change equipment more frequently than higher-level systems (and one power distribution computer system has jurisdiction over several hundred or more distribution lines as a power distribution system). Due to reasons such as the need to manage dozens or more distribution line switches, etc., power distribution computer systems must frequently maintain a large amount of distribution line equipment data, as well as data maintenance for distribution system diagrams. It's in a place where it shouldn't be.

In addition, in the substation computer system, the operator designs the layout for each component of the screen.

An interactive drawing method is used in which settings are made using a light pen, keyboard, etc., taking into account the shape of the symbol, etc. Therefore, even in power distribution computer systems, power distribution systems can be displayed or drawn using the same method. It is possible to do so.

[Problem that the invention seeks to solve]

However, when using the above-mentioned screen drawing method for power distribution computer systems, the operator must decide the screen configuration (layout) by himself during maintenance (during data maintenance) and set the symbols, which takes a long time. There is a problem in that it requires time and data maintenance cannot be performed on N-1-.

Therefore, it is an object of the present invention to provide a drawing method that uses an hour wheel and can draw a drawing in a short time.

[Means for solving problems]

In order to display the distribution line on a CRT screen through computer processing, we define each component that makes up one section of the distribution line.
Display rules for displaying each component are determined in advance, and when a drawing command is given after inputting the data regarding the power distribution line required for display,
The layout on the CRT screen is determined from this input data and display rules, and each component is displayed on the CRT screen.

[Effect]

The on-screen layout is determined based on input data including the presence or absence of distribution switches and sections, and section connection data, and predetermined display rules, and the components of the distribution line are displayed as their skeletons according to this. By displaying only the
Make it easy to handle changes and additions.

〔Example〕

FIG. 1 is a flowchart showing an embodiment of the invention, and FIG.
The figure is an explanatory diagram for explaining the drawing data manually generated during maintenance and an example of the drawing, Fig. 3 is a block diagram showing a computer system to which this invention is applied, and Fig. 4 shows the components of one section of the distribution line. FIG. 5 is an explanatory diagram for explaining display rule (3), and FIG. 6 is an explanatory diagram for explaining display rule (4).

First, explanation will be given starting from FIG. That is, the computer system to which this invention is applied includes a computer main body (CPU) 1, CR
It consists of T devices 2A, 2B and a memory 3 such as a disk. Here, the CRT device 2A is used for inputting data, and the CRT device 2B is used for checking input data.

The input data is stored in the memory 3, and when a predetermined drawing command is given, the CPU determines the layout on the screen based on this input data and display rules, and transfers it to the CRT2B.
View via.

Here, the display rules for one section of the distribution line are determined as follows.

(1) The components for one section are as shown in Figure 4: Main switch a Line of the immediately preceding section (rising cable for the first section) b Line of own section C Linkage switch d Line of own section for linkage switch e is defined as consisting of a line f of the linked light section. In addition, columns 1 to 5 in Figure 4
indicates the section number, and thus symbols a to f are examples of the components of section number 4.

(2) The first section is fixedly displayed at a predetermined position on the screen.

(3) The second and subsequent sections are displayed on the right side of the immediately preceding section.

If there are multiple sections with the same previous section number, the section with the larger section number is displayed as the branch side, and is displayed in a lower row. This is explained in Figure 5. When the second and third sections have the same immediately preceding section number, the third section with the larger section number is determined to be the branch side and is lowered to the bottom and displayed as shown in the figure. .

(4) When branching into multiple sections, the section on the power supply side (the section closer to the first section) is displayed one step lower so that the sections on the branch side are not lined up in the same row. This is explained in FIG. 6, where between the fourth section and the fifth section, the fourth section is on the power supply side, so the fourth section is displayed one step lower.

On the other hand, the data related to the distribution line, which is input as drawing data, includes: a) number of sections of the distribution line; b) immediately preceding section number indicating the connection status of the section; Yes, this is the third
The data is input to the memory 3 shown in the figure. Therefore, CP in Figure 3
When U1 is given a drawing command, it determines the layout on the screen based on the input data shown in A) to C) above and the display rules shown in (1) to (4) above, and then displays the layout as shown in Figure 1. Perform processing according to the flow and form the screen.

Below, FIG. 1 will be explained.

First, after determining the number of sections (see ■), display the main line □ closure in the position determined by the display rules (see ■)
. Next, determine whether it is the first section or not (see ■), if it is the first section, display the rising cable (see ■), and if it is other than the first section, display the line of the previous section (see ■). Then,
After displaying the line for the own section (see ■), determine whether or not the interlock switch is installed (see ■), and if so, display it (see ■), then check the connection switch for the interlocking distribution line. Display the line of its own interval (see ■). Thereafter, it is determined whether or not there is any further linked light (see 0), and if there is any linked light, a line of the link destination section is displayed (see ■).

Thereafter, the process returns to step (2) again, and the process is repeated a number of times corresponding to the number of sections, and ends.

Therefore, for example, when drawing data as shown in FIG. 2(a) is given, drawing as shown in FIG. 2(b) will be performed. That is, according to the display rule (2) above, the first section is displayed at a fixed position in the upper left of the screen, and the second to sixth sections are displayed on the right side according to the display rule (3). At this time, the second. 3rd ward question and 5th ward question. The 6th section has the same immediately preceding section number, so according to display rule (3), the 3rd. 6th
The sections are displayed at the bottom, and the third section is further lowered by one step according to display rule (4), resulting in the display as shown in FIG. 2 (b).

Note that the distribution line diagram displayed in this way is only its skeleton and does not correspond to the actual position (on the map), but it is sufficient from the viewpoint of easy maintenance. It is something that performs a function. Furthermore, even if there is a change in the section constituent elements of the distribution line, or if a distribution line with a different section configuration is to be drawn, this can be easily handled by changing the display rules.

〔Effect of the invention〕

According to this invention, since drawing is automatically performed based on the input data and display rules for drawing, there is no need for the operator to determine the layout etc. on the screen (compared to interactive drawing methods). This has the advantage that the method according to the present invention can significantly reduce the time required (about 10 minutes, compared to about 3 hours in the case of an interactive method).
