Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention uses a computer and a graphic display device connected thereto to connect multiple lines or conduits constituting a communication system for electric power, gas, water, etc. The present invention relates to a graphic display device that displays images all at once.

[Technical background of the invention and its problems]

In recent years, for example, the configuration of power distribution systems has become increasingly complex as demand has increased, and systems have become congested, especially in urban areas.

By the way, when displaying multiple power distribution lines all at once on a graphic display device for the purpose of managing and operating such a power distribution system, since the power distribution system has a wide area, it is difficult to see which area a power distribution line is connected to. It may be difficult to determine whether a power distribution line is being supplied by a power source, and it may be difficult to distinguish between overhead and underground distribution lines in areas where both overhead and underground distribution lines coexist. Therefore, simply displaying the power distribution system diagram all at once on the display screen of a graphic display device may lead to erroneous judgments when operating the system.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to simply specify a particular line or conduit among the lines or conduits collectively displayed on a graphic display device; It is an object of the present invention to provide a graphical display device that can clearly distinguish it from pipes and prevent erroneous judgments in system operation.

[Summary of the invention]

In order to achieve such an object, the present invention uses an electronic computer and a graphic display device connected thereto to graphically display a plurality of lines or conduits constituting a power, gas, water, etc. system. Configure the above system in a graphic display device! , a storage device that stores information on a plurality of lines or conduits and display colors predetermined for these lines or conduits according to the status of the system, and a graphic display device that collectively displays graphics on the graphic display device. When a specific line or conduit among the displayed lines or conduits is specified, information on the display color corresponding to this line or conduit is successively outputted from the storage device, and only this specific line or conduit is predetermined. The present invention is characterized by comprising means for displaying in a display color, and for displaying other lines or conduits that are not specified in a single color different from the display color of the specific line or conduit.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example of a configuration in which a graphic display device according to the present invention is applied to display on a screen the connection status of a plurality of power distribution lines constituting an electric power system. In Fig. 1, 1 is a storage device that stores information on multiple distribution lines constituting an electric power system and display colors predetermined for these distribution lines according to the status of the system, and 2 is an arithmetic control unit. This arithmetic and control device 2 has an information input device 3 that receives status signals of devices such as circuit breakers and switches transmitted from the actual power system, and displays a plurality of distribution lines including the device status of the power system. A graphic display device 4 is connected to each display device. Reference numeral 5 denotes a display content designation device, which allows the operator to designate a specific distribution line among the plurality of distribution lines displayed on the graphic display device 4 to the arithmetic and control unit 2. . When a specific distribution line is designated by the display content designation device 5, the arithmetic and control device 2 reads out display color information corresponding to the designated distribution line from the storage device 1 and displays it on the graphic display device 4. Means for displaying the corresponding distribution line in a predetermined display color and information input device 4
It is provided with data updating means for rewriting data contents in the storage device 1 when a device status change signal from the actual system is input.

Next, the operation of the graphic display device constructed as described above will be explained with reference to the display screen shown in FIG.

In Fig. 2, the symbols M and △2 represent the switches, the line segments connecting these switches represent the distribution line, and the symbol A%' represents the rising point of the distribution line. shows the rise point of the cable system along with the switch.

Now, the graphic display device 4 displays the image shown in FIG. 2(a).
It is assumed that a power distribution system diagram like the one shown on the left side of the diagram is displayed. In such a state, when the operator specifies one distribution line in the display content designation device 5, the arithmetic and control unit 2 reads out display color information corresponding to this specified distribution line from the storage device 1. This is displayed on the corresponding distribution line displayed on the graphic display device 4 in a predetermined display color as shown in the right screen of FIG. 2(a), and for other distribution lines that are not specified. is forced to display in a predetermined single color instead of the display color stored in the storage device 1. Therefore, one designated power distribution line stands out and becomes clearer than other power distribution lines, so that it can be easily determined to what range this designated power distribution line supplies power.

Further, when the graphic display device 4 displays a distribution system diagram in which overhead distribution lines and underground distribution lines coexist as shown in the left side screen of FIG. When specifying the content, for example, an underground distribution line, the arithmetic and control unit 2 searches the storage device 1 for display color information corresponding to the specified underground distribution line, reads this information, and displays it on the graphic display device 4. The corresponding underground distribution line is displayed in a predetermined display color as shown in the right screen of Figure 2 (b),
Storage device 1 is used for other distribution lines that do not correspond to the specified contents.
Forcibly display a predetermined single color instead of the display color stored in the .

Therefore, underground power distribution lines that match the specified content stand out more clearly than overhead power distribution lines that do not match the specified content, so that it is possible to easily distinguish between underground power distribution lines and overhead power distribution lines.

In addition, in the above embodiment, the specification content of the electric power system is described in which the overhead distribution lines and underground distribution lines are distinguished, but the specification content is not limited to this, and any content depending on the type can be used. Of course, it would also be fine to use something like that. Furthermore, in the above embodiment, the case where multiple power distribution lines constituting an electric power system are displayed on the screen together with the power distribution equipment is described, but the same applies to the case where systems such as gas and water 2 communication systems are displayed on the screen. It is something that can be implemented.

〔Effect of the invention〕

As described above, according to the present invention, when a specific line or conduit is designated among the lines or conduits graphically displayed all at once on the graphic display device, multiple lines or conduits constituting the system can be The display color information corresponding to this line or conduit is read out from a storage device that stores display color information predetermined for these lines or conduits according to the system status, and the display color information corresponding to this line or conduit is read out. Only the route is displayed in a predetermined display color, and other lines or conduits that are not specified are displayed in a single color that is different from the display color of the specific line or conduit. By simply specifying a specific line or conduit among the displayed lines or conduits, it becomes possible to clearly distinguish it from other lines or conduits, thereby preventing misjudgment in system operation. It is possible to provide a graphic display device that can.
