In the above-mentioned prior art, the information on the direction / plane position is expressed on the display, but the information on the height (hereinafter, the depth is also expressed as the height) is not. Not displayed. For example, when laying a new underground distribution line, make sure that the gas pipes are not adjacent (see Fig. 6x), or if the gas pipes are adjacent, change the depth of the distribution line so that they are not adjacent. It is necessary to consider such things in the power system transmission line expansion plan. However, since the conventional system does not display information about the height, such a study is performed by humans. As described above, in the system of the related art, since the information on the height is not displayed, there are cases in which the expansion plan of the electric power system and the monitoring of the operating state are hindered. To solve this problem, the data h ₁ of height map data 1, the high data h ₂ was added to the electric power system equipment 2, it is necessary to adopt a three-dimensional graphic display to the display terminal 5 and the display controller 4 .. However, the three-dimensional graphic display is expensive and slow in display speed, so that it is not suitable for the application of this system at the current technical level. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a display device for a power system capable of displaying the power system in consideration of height information at the same cost and display speed as those of the related art. I am trying.

[0004]

In order to achieve the above object, the present invention provides a two-dimensional display device for displaying a power system diagram composed of power transmission lines, distribution lines, utility poles, etc. of a power system.
By adding a device that converts height information into color gradations and displays it, it is possible to display the height of power system equipment and various equipment included in maps, and to identify the degree of adjacency between each equipment. And

In the power system diagram, the mutual relationships in height between power facilities and other map information can be identified, which is convenient when expanding facilities.

Embodiments will be described below with reference to the drawings. Figure 1
FIG. 4 is a configuration diagram of an embodiment of a display device for a power system according to the present invention. In the figure, the same parts as those in FIG. 6 is height data (h ₁ ) provided in the map data 1, 7 is height data (h ₂ ) provided in the power system equipment data 2, and 8 is height data (D) provided in the display controller 4. _h ), in which h ₁ , h
₂ is simply the addition of data. The function of D _h of 8 will be described with reference to FIG. Data display controller 8 of the height of the display controller 4 data h ₁ of the height of the map data, enter the data h ₂ of the height of the power system equipment, determine the color tone according to its height.

This is performed as follows by using the upper limit value h _max and the lower limit value h _min of the height data and the corresponding color tones c _max and c _min . That is, if 1 h ₁ and h ₂ are larger than h _max , the color tone is c _max 2 h ₁ , and if h ₂ is smaller than h _min , the color tone is c _min 3 h ₁ and h ₂ is an intermediate value between h _max and h _min . Time Calculate. Then, among the possible color tones of the display terminal 5, the one having the closest calculated value is selected as the color to be displayed. Input this color tone into the display controller 4,
The height data of each equipment is displayed in color tones by combining with other graphic display data. As a result, for example, height 0m
The distribution line b is white. The 10m high distribution line is red. 0-9m
During this period, the red color tone becomes stronger as the height increases by 1 m. In other words, it is displayed as white (0 m) → slightly reddish → sequentially red becomes stronger → red (10 m), and it is necessary to distinguish the approximate height of facilities and facilities and the relative difference between them by color. You can

In this area, the color tone S _j for each of the basic display colors H _i (about 16 colors) is set to RGB.
It is determined in advance by a combination of gradations of and stored. The inner S ₁ of S _j to c _min, performs display in correspondence to S _m in c _max. As a result, color tone display can be performed in the range of S _{1 to} S _m .

The processing contents will be described below with reference to the flowchart of FIG. First, in step S41, the map data and equipment data to be displayed are extracted, and in step S42, the height data held in the map data and equipment data is determined. Here, the range of the height data h (h ≦ h
_{According to max} , h ≦ h _min , h _min <h <h _max ), the steps are respectively assigned to steps S43, S44, and S45. In each step, the color tone corresponding to the height data h is determined. Next, in step S46, the basic display color of the map or equipment to be displayed is taken out, and in step S47, the basic display color and the color tone data (S _j ) corresponding to the color tone are taken out from the color tone storage area of FIG. Finally, the color tone (S _j ) extracted in step S48 is used for display. Based on this color tone data, the map and facility displays can be displayed in color tone, and the height can be recognized from the graphic display.
