Abstract

(57) [Summary] [Purpose] The objective is to obtain a symbol placement method that allows symbols to be placed so that they do not overlap with other equipment or topographic maps on the mapping screen. [Structure] When a placement candidate site is set in the vicinity of the facility in advance, a priority order is set for the placement candidate site, and a symbol is placed on the placement candidate site, other facilities and topography on the mapping screen are displayed. Whether or not it overlaps with the map is determined sequentially from the placement candidate sites with higher priority, and the symbol is placed at the placement candidate site that was first determined not to overlap with other equipment or topographic maps. ..

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a symbol arrangement method for arranging symbols on equipment displayed on a mapping screen.

[0002]

2. Description of the Related Art FIG. 5 is a block diagram showing a drawing display device to which a conventional symbol arrangement method is applied. In the drawing, 1 is a storage device for storing drawing data (topographic map data, facility data), and 2 is a storage device. A server for updating and reading the drawing data stored in the device 1, 3 is a LAN, and 4 is a server 2.
It is an EWS (workstation) that receives drawing data from the computer and displays a mapping screen on the CRT 5.

Next, the operation will be described. The mapping screen is displayed on the CRT 5 when the EWS 4 receives the drawing data from the server 2.

Here, when a symbol is placed on any facility on the mapping screen, it is placed on the facility or the like without any choice as shown in FIG.

[0005]

Since the conventional symbol arranging method is constructed as described above, when arranging the symbols in the equipment, there is no choice in the arrangement place, and therefore the symbols are not displayed on the mapping screen. There was a problem that it might overlap with the equipment and the topographic map.

The present invention has been made to solve the above problems, and an object thereof is to obtain a symbol arranging method capable of arranging symbols so as not to overlap with other equipment or topographic maps on the mapping screen. To do.

[0007]

In the symbol arrangement method according to the present invention, an arrangement candidate site is defined in the vicinity of equipment in advance, and a priority order is established for the arrangement candidate site.
When a symbol is placed on the placement candidate site, whether or not it overlaps with other equipment or topographic maps on the mapping screen is determined in order from the placement candidate site with the highest priority, and it does not overlap with other equipment or topographic maps. The symbol is arranged at the arrangement candidate site that is first determined to be.

[0008]

In the symbol arranging method according to the present invention, when the symbols are arranged at the arrangement candidate sites, it is sequentially determined from the arrangement candidate sites having the highest priority whether or not they overlap with other equipment or the topographic map on the mapping screen, By arranging the symbol at the placement candidate site that was first determined not to overlap with other equipment or topographic maps, the symbols will be placed as appropriate under the condition that they do not overlap with other equipment or topographic maps. It

【Example】

Example 1. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a flow chart showing the operation of a symbol arrangement method according to an embodiment of the present invention.

Next, the operation will be described. Before arranging the symbols, as shown in FIG. 2, an allocation candidate site is set in the vicinity of the equipment in advance. In this example, the number of candidate locations for arrangement is set to be eight, and the highest priority is set just above the equipment and the lowest priority is set at the upper left of the equipment.

When actually arranging symbols, first,
EWS4 any equipment on the mapping screen of CRT5
It is selected using the keyboard of, the touch panel of the CRT 5 or the like (step ST1). Here, FIG. 3 is an example of the mapping screen, and in this example, since three equipments are displayed, the equipment is selected from the three equipments.

Next, the shape of the symbols to be arranged (for example,
◯, Δ, □), color (for example, red, blue) or the like is selected by the keyboard of the EWS 4 or the touch panel of the CRT 5 (step ST2).

Here, when the symbols selected in step ST2 are arranged at the arrangement candidate sites shown in FIG. 2, whether or not they overlap with other equipment or topographic maps on the mapping screen is determined by the arrangement candidate having a high priority. It is sequentially determined from the ground (steps ST3 to ST5). For example, when arranging a symbol on the equipment on the far right side of FIG. 3, if the symbol is arranged on the candidate location for the first priority (just above the equipment), the topographic map (house) will be displayed.
Therefore, it will be placed at the candidate location for the second priority (just below the equipment) (step ST
7). In addition, in this example, although it is arranged at the layout candidate site of the priority order 2, if it is arranged at any of the priority orders 1 to 8 when it overlaps with other equipment or the topographic map, it is forcibly forced. It is arranged to be arranged at the arrangement candidate site having the first priority (step ST9).

Example 2. In addition, in the above-described first embodiment, the description has been given of the case where the eight placement candidate sites are set in the vicinity of the facility. However, as shown in FIG. 4, the placement candidate sites are set in a spiral shape,
The inside of the spiral may have a higher priority.
By doing so, the symbol can be automatically arranged at the position closest to the facility under the condition that it does not overlap with other facilities or the topographic map.

[0015]

As described above, according to the present invention, the placement candidate sites are set in the vicinity of the equipment in advance, the priority is set for the placement candidate sites, and the symbols are placed at the placement candidate sites. In this case, it is sequentially determined whether or not it overlaps with other equipment or topographic maps on the mapping screen from the placement candidate sites with the highest priority, and the placement candidate site first determined not to overlap with other equipment or topographic maps. Since the symbol is arranged on the map, there is an effect that the symbol is arranged at the most preferable position under the condition that it does not overlap with other equipment or topographic maps.

Claims (1)

[Claims] 1. A placement candidate site is set in advance in the vicinity of the facility in order to select one of the facilities displayed on the mapping screen and place a symbol in the vicinity of the selected facility. If the symbol is placed in the placement candidate site, whether or not it overlaps with other equipment or topographic map on the mapping screen is determined sequentially from the placement candidate site with the highest priority. , The symbol placement method that places the symbol at the placement candidate site that was first determined not to overlap with other equipment or topographic maps.
