Abstract

PURPOSE:To offer convenience to a user by displaying, and a map itself, mutual relation between adjacent maps and their connection by using a means which displays another divided maps whose central part is the boundary between the adjacent maps. CONSTITUTION:For example, since the map an operator intended to have at first is not a map 101 but the map in the northeast, a map 103 is displayed; however, the required map is not 103 either but the map whose central part is the boundary between the maps 101 and 103, and therefore a map 102 is displayed. In that way, the operator can display the map 102 when he wants to grasp the relation between the maps 101 and 103. That is, the relation between the maps 101 and 103 can be displayed as a collection 102 of another four divided maps, whose central part is the boundary between both the maps 101 and 103. Thus, the mutual relation between the adjacent maps can be grasped at a glance, and map retrieval and reference can be accurately and speedily achieved.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for displaying a map on a display device, such as monitoring and controlling power distribution related to electric power by displaying a map, and controlling roads related to traffic. The present invention relates to a map display method suitable for map display systems such as guides.

[Conventional technology]

The use of display devices such as CRTs to display maps is widespread. This display is.

Generally, a certain portion of a map is displayed, and therefore it is not easy to understand the entire map or the connections and relationships between one map and another map.

In order to grasp the relationship between maps adjacent to each map, it is necessary to perform the following operations.

For example, if it is desired to see the relationship between adjacent maps, it is necessary to display each map separately or to display them one on top of the other as in Japanese Patent Application Laid-Open No. 143835/1983. Therefore, it is not possible to see the relationship between adjacent maps at a glance.
It is not easy to understand mutual positional relationships, road routes, etc.

In Japanese Patent Application Laid-open No. 157976/1984, an attempt is made to display maps in eight adjacent directions using a simple operation method so that the mutual relationship between the divided maps can be clearly understood. This method is a method of displaying each adjacent map separately.

[Problem to be solved by the invention]

However, in such conventional methods, each map is displayed separately in order to grasp the mutual relationship between adjacent maps. It is necessary for humans to draw a connection with the displayed map in their heads. Furthermore, if the map cannot be grasped in one display, it is necessary to redisplay the map several times.

Also, when there are three or more maps that are in contact with each other, the burden on the human head becomes even greater, and it becomes difficult to obtain accurate and precise maps.

It is difficult to understand quickly.

As described above, the conventional method has the problem that it is inconvenient to grasp the mutual relationship between adjacent maps, and it takes time to grasp it accurately. Further, it cannot be said that the convenience for map users, the man-machine nature of map display, and the operability are sufficient.

SUMMARY OF THE INVENTION An object of the present invention is to provide a map display method that solves the conventional problems and satisfies both the convenience of use for users and the improvement of man-machine operability.

[Means to solve the problem]

The above object is achieved by displaying the interrelationships and connections of adjacent maps as a new map itself by means of displaying a map that is newly divided with the boundary portion of the adjacent maps as the center. In addition, in the display editing method for adjacent maps, all maps in 8 adjacent directions are displayed without interruption in the field of view that is the display area, and the map is moved and displayed in any direction among the 8 directions. It is displayed and edited as a collection of divided maps so that it can be edited.

[Effect]

Conventionally, adjacent maps were basically
There are no duplicate parts. In some cases, there may be some overlap.

However, in the present invention, since the mutual relationship between adjacent maps is displayed as a collection of new divided maps, contrary to the conventional method, it is possible to display overlapping parts as if they exist in the field of view, contrary to the conventional method. can. With this method, it is possible to grasp the interrelationships of adjacent maps at a glance.

〔Example〕

An embodiment of the present invention will be described below.

FIG. 1 is a block diagram showing the configuration when the present invention is applied to a map display system.

FIG. 2 is a diagram showing map display and editing contents and methods in Example-1. FIG. 3 is a display example of the map.

Hereinafter, operator operations, map display/editing, and display methods will be explained based on FIGS. 2 and 3.

First, a state in which operator 5 specifies a map to be displayed from the map menu and then displays a rectangular map 101 will be described.

All maps described below have a rectangular structure. The map 101 is divided into four divided maps 11°12.13.
It is a collection of 14. At this time, the map adjacent to the northeast direction of map 101 is map 103, which is a collection of maps 24°31.32.33.

Therefore, the map 102 is divided into four divided maps 14°23.24.2 with the boundary between 101 and 103 as the central part.
It is a collection of 5. Similarly, the map adjacent to map 101 in the south direction is map 105, which is a collection of maps 19°, 20, 34, and 35.

Therefore, the map 104 is divided into four divided maps 12゜13.19.2 with the boundary between 101 and 105 as the center.
It is a collection of 0s. In this way, a new collection of maps that are adjacent to each other in eight directions of the map 101 and whose central part is the boundary between the two maps is determined using the same procedure.

Next, an example of a map search will be explained.

The map that the operator originally planned was not 101,
Map 103 was displayed because it was a map in the northeast direction.

However, the map I need is not 103, but 101.
Since it was a map with the boundary between 102 and 102 as the central part,
102 maps were displayed. In this way, when the user wants to understand the relationship between the map 101 and the map 103, the map 102 can be displayed. That is, map 101 and map 1
The relationship of 03 is a new 4 whose center is the boundary between the two.
It can be displayed as a collection 102 of divided maps.

Further, the operations by the operator are performed by the operation section shown in FIG. 4. The operating method will be explained below.

The map display and editing contents in FIGS. 2 and 3 correspond to this operation section, and the map 101 in FIGS.

Corresponding to ■ in FIG. 4, the map 103 corresponds to ■, and the map 102 corresponds to ■.

In this way, all the maps adjacent to the map 101 in eight directions correspond to each other in the same way. Therefore, when displaying the map 102 from the map 101, specify the operation panel ■ and
When displaying 03.

Specify the operation section ■. Similarly, map 101 can also be specified from map 103'. At this time, specify ■,
When map 103 is displayed.

The displayed editing content is updated as a collection of four divided maps adjacent to each other in eight directions of the map 103.

Therefore, when displaying a map adjacent to map 103,
This can be done using exactly the same procedure as when displaying a map adjacent to the map 101. Furthermore, a completely different map display can be specified from the map menu.

As described above, maps adjacent to a certain map in eight directions can be displayed arbitrarily.

The operation section may be provided on the keyboard or on the CRT, and either may be used.

When provided on a keyboard, the key configuration is shown in FIG.

The key consists of a 0-0 part centered on ■ and a 0-0 part centered on ■.

Next, when the operating section is provided on the CRT, there are the following advantages compared to when it is provided on the keyboard.

For example, by providing the operation panel shown in Figure 4 on a CRT, you can change the display color of ■ or ■ to ■ to determine which of ■ to ■ the currently displayed map is. This can be achieved by

Based on the above, next, the block diagram of FIG. 1 will be explained.

The entire map data is stored in the map data storage unit as a collection of divided map units shown in FIG. 2, that is, in divided units. A series of NO's are attached to these division units, and the adjacency relationship of each division unit is stored in the map division information storage section.

Next, the contents of the operator's operation are input through the operation input device to specify which map is to be displayed, and the map specifying section passes the specified contents to the map search section. The map retrieval unit retrieves the data of the division units of the map corresponding to maps 11 to 26 shown in FIG. 2 from the map data storage unit to the map display editing unit while referring to the map information storage unit, and after editing, sends the data to the display device. Displayed and output. At the same time, the map display state storage unit stores the display state in association with the edited division unit number, so that when the map display is changed,
Used as management information for the map search section.

In the above embodiment-1, the map is displayed as a collection of four divided maps, and the field of view of the map on the display device is equal to the collection of four divided maps, but another embodiment -2 will be explained.

FIG. 6 is a diagram showing map display and editing contents and methods in Example-2. The explanation will be given below according to FIG.

When displaying and editing a map, the map 106 is edited as a collection of nine divided maps 51 to 59. At the same time, a collection of nine divided maps in eight directions adjacent to the map 106 is also displayed and edited. This map 106 is defined as a basic map, and all maps in eight adjacent directions are defined as moving maps.

All of these basic maps and moving maps are displayed and edited as virtual planes on a display device.

After the display editing, the basic map 106 is initially in the field of view position. Let us consider a case where the map within the visual field is moved from this state, for example, in the northeast direction.

If you specify the northeast arrow on the operation panel shown in FIG. 8, the map in the field of view will move to the northeast. For example, if you move one division unit, the map in the field of view will move from the map 106 shown in FIG. 7 to the northeast.
Move to 07. Furthermore, if you move one piece, it will be 107
It can be moved from 108 to 108. Furthermore, since it is a virtual plane, movement within one division unit is also possible. In this way, any map on the virtual plane can be moved to the viewing position, and the interrelationships in eight directions adjacent to the basic map can be easily grasped.

Furthermore, when the map is moved to the position of the moving map 109 in FIG. 6, a new display editing is performed using 1o9 as the basic map.

As described above, it is possible to move the map continuously using a limited display field of view, and it is effective in terms of man-machine performance and operability as a method for grasping the relationship between adjacent maps. .

As another example, the basic map is 51 shown in FIG.
If all other maps are considered as moving maps, it is equivalent to the above, and furthermore, the basic map is 51 and the moving maps are 52 to 5.
The same applies if the number is limited to 9.

〔Effect of the invention〕

As described above, the present invention has the following effects.

1. When displaying maps in eight directions adjacent to a certain map, you can display a new map with the boundary between one map and another adjacent map as the center, so you can see the relationship between the adjacent maps at a glance. can be grasped.

2. By displaying the above-mentioned item 1 and adjacent maps by specifying the direction of the map, it is possible to search and refer to maps accurately and quickly.
