Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power system display system used for monitoring a power system.

[0002]

2. Description of the Related Art A map information system, which is one of CAD systems, is used in order to grasp the arrangement state of steel towers and transmission lines of a power system. Using CAD, circles and straight lines are used to symbolize the positions of the towers and power lines on the two-dimensional map displayed on the CRT screen, and the heights of the towers and power lines are displayed on these circles and straight lines. Attribute the data such as the number and thickness of. Operation is a method of displaying the data that has been pre-assigned, that is, the numerical data such as the height of the tower, the number of transmission lines, and the thickness, on the CRT screen by specifying the circle or straight line on the CRT screen with the cursor. Is.

[0003]

According to the prior art, C
Since the symbol displayed on the RT screen is designated by the cursor and the information of the transmission line that has been symbolized is displayed numerically, it is difficult to intuitively understand the arrangement of the transmission line and the connection information of the number of lines. Is. The present invention has been made to solve the above drawbacks, and provides a power system display system capable of intuitively grasping device information by displaying three-dimensional information based on two-dimensional map information. It is intended to be provided.

[0004]

In order to achieve the above object, the present invention uses a CAD system of a computer to symbolize a two-dimensional map and a power system such as a tower or transmission line on the CRT screen. The map information means for displaying, the three-dimensional solid model creating means for creating individual parts of the power system (steel towers, transmission lines, etc.) in the computer as a three-dimensional solid model, and the map information displayed on the CRT screen By designating an arbitrary power system with a cursor, a means for displaying the three-dimensional solid model of the part on the CRT screen is provided. By designating the solid model with the cursor, detailed numerical values of the power system are provided. It also has means for displaying data.

The map information means uses the CAD system of the computer to symbolize the towers and transmission lines on the two-dimensional map with circles or straight lines and display them on the CRT screen. The three-dimensional solid model creating means creates individual parts of the power system (steel towers, transmission lines, etc.) in the computer as a three-dimensional solid model.
The attribute assigning means attributes the symbol and the three-dimensional solid model, or attributes the three-dimensional solid model and numerical data such as a steel tower. The three-dimensional graphic display means displays a three-dimensional solid model of the portion on the CRT screen by designating an arbitrary symbol in the map information displayed on the CRT screen with a cursor. Further, by designating a solid model with a cursor, detailed numerical data regarding the model is displayed.

Embodiments Embodiments will be described below with reference to the drawings. FIG. 1 is a block diagram of an embodiment for explaining a power system display system according to the present invention. In the figure, 1 is a computer, and this system has a map information processing means 100, a three-dimensional solid model creating processing means 110, an attribute assigning processing means 120, and a three-dimensional attribute display means 130. CRT with keyboard 2 and mouse 3 for displaying
It is composed of a display 4.

Next, the operation will be described. First, the map information processing means 100 symbolizes a power system such as a tower or a power transmission line and displays it on the CRT screen. This will be described with reference to FIG. The map 5 that has been read in the computer is displayed on the CRT screen in advance, and by using CAD, symbols such as a circle mark indicating a steel tower and a bar mark indicating a power transmission line are displayed at the positions of the steel tower 6 and the transmission line 7 as a map. Correspondingly displayed. In the three-dimensional solid model creation processing, a steel tower and a power transmission line are created as they are by using a three-dimensional solid model creation technique. This three-dimensional solid model generation technology is a combination of basic solids (primitives) such as a cylinder 8, a sphere 9 and a prism 10 as shown in FIG. 3 (a), and a tower as shown in FIG. 3 (b). This is a technology for generating complicated shapes such as electric wires in a computer. This database is composed of solid model names, dimension data of primitives that are component parts, coordinate axes, and the like. Then, it is possible to display the attitude of the steel tower and the power transmission line from any direction on the CRT screen as if the real thing exists. This technology is used to create solid models of towers and transmission lines.

In the attribute assigning process, the map information and the solid model are associated with each other. As shown in Fig. 4 (b), the symbols of individual towers and transmission lines on the map of the target area and the corresponding 3D solid model name are associated as shown in Fig. 4 (a). Although the three-dimensional attribute display is actually used, the map 12 of the target portion is displayed in a part of the window of the screen as shown in FIG. 5 by using the multi-window which is a recent CRT display technology. . By designating the range 13 desired to be displayed as a three-dimensional solid model on this map with the cursor, the solid model which is the attribute of the symbol included in this area is displayed in another window 14. Further, by selecting a solid model with a cursor, detailed data of the model, for example, the height of the tower, the thickness of the electric wire, and the like in which the solid model is created are displayed in another window 15 to be confirmed as numerical data. be able to.

[0008]

As described above, according to the present invention, it is possible to reproduce the three-dimensional actual power system condition on the CRT screen from the two-dimensional map information, so that the number and types of electric wires can be easily obtained. You can grasp the situation of the site.
