Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a map retrieval device, and more particularly to a map retrieval device capable of filing, displaying, and searching map information.

Prior Art In conventional map search devices, X and Y addresses are attached to each point at regular intervals on a map and stored in advance as map information, and by specifying these X and Y addresses, the target can be found. The location was controlled to be displayed on the display. Further, symbols registered in advance with X and Y addresses can be superimposed and displayed on the map information as code information. Furthermore, apart from map information,
You can register drawings that are managed on a page-by-page basis.

These drawings are stored with a page attached to each drawing in addition to the drawing number, and by specifying the drawing number and page, the desired drawing can be displayed on the display. Therefore, since the map information and the drawings are each independent, there is no correlation between them.

In this conventional map search device, in order to display a target point as map information, some method is used, such as connecting online to a host computer and specifying X and Y addresses from a post computer, or referring to a table of contents, etc. The user locates the X and Y addresses of the destination point and enters them using a keyboard or the like.

Also, if you want to display symbols on the map, you can instruct symbol display from the host computer or keyboard to display the symbols registered at the X and Y addresses within the display range of the screen, superimposed on the map. can do.

However, if information related to the map information and symbols currently displayed here is registered as a drawing,
For example, even if the floor plan of a building on the displayed map is registered as a drawing, the drawing has no relationship with the X and Y addresses, so the drawing number must be specified again from the host computer or keyboard. It had the disadvantage of being annoying and annoying.

OBJECTS OF THE INVENTION The present invention has been made to solve the above-mentioned conventional drawbacks, and its purpose is to provide a map search device that can display drawings related to symbols on a map with a simple operation. It is to be.

Structure of the Invention A map search device according to the present invention comprises a map storage means for storing and holding a map, a symbol storage means for storing and holding a plurality of symbols indicating search points on the map, and image information corresponding to the symbols. an image information storage means for holding, a display means for displaying the map and the symbol, a symbol designation means for designating a search target among the symbols, and a symbol corresponding to the symbol designated by the symbol designation means among the image information. and display control means for controlling to display what is displayed in place of the map and symbols.

Example Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of a map search device according to the present invention. In the figure, an optical disk device 3
Map information and drawings are stored therein as image information, and the map information or drawings are read out from the address specified by the image storage address calculation section 1. The read map information or drawing is written into the frame memory 6 via the output information switching section 5. As a result, a map or a drawing of a building or the like is displayed on the display 7. Note that the first page of the drawing is displayed on the display screen. Therefore, when it is desired to display the second and subsequent pages, or conversely when the previous page is desired to be displayed, the display is switched by pressing a key on the keyboard (not shown).

Further, the symbol and drawing number output unit 4 outputs a symbol or a drawing number to be displayed on the map in accordance with the address designated by the symbol and attribute information storage address calculation unit 2. This symbol and drawing number output section 4 is
As shown in FIG. 3, there is a selector 40 that is switched by specifying a symbol/attribute using a keyboard (not shown), and a table 41 that outputs code information of the symbol corresponding to the address depending on the human power of the address. , and a table 42 that outputs the drawing number corresponding to the address in response to the input of the address.

In other words, when a symbol is specified using a keyboard (not shown), the code of the symbol corresponding to the address is sent out in response to an address input from the address calculation unit 2.
It is written into the frame memory 6 via the output information switching unit 5. As a result, a screen in which the symbol to be searched for is superimposed on the map is displayed on the display 7.

On the other hand, if an attribute is specified using a keyboard (not shown), in response to an address input from the address calculation section 2, a drawing number corresponding to the address is sent out and input to the image storage address calculation section 1. As shown in FIG. 2, the image storage address calculation unit 1 includes a table 10 that outputs the optical disk address in which the drawing is stored in accordance with the input of the drawing number, and an input of the X and Y addresses. Table 1 outputs the optical disk address in which the map information corresponding to that address is stored.
1.

In other words, if you specify the X and Y addresses of the symbol on the map,
A drawing number is sent from table 42, and an optical disk address is sent from table 0. As a result, image information of the drawing corresponding to the designated symbol is sent from the optical disk device 3 and displayed on the display 7.

Returning to FIG. 1, the output information switching unit 5 selects the map or drawing and symbol from the optical disk device 3 and the symbol from the drawing number output unit 4 in response to the designation of a symbol/image using a keyboard (not shown). This is for uniform output.

As described above, there are three types of screen displays on the display 7. That is, there are three types: a map only, a map and symbol, and a drawing. Next, the display operations of these three types of screens will be explained.

In FIG. 1, when displaying map information, X and Y addresses are input to the image storage address calculation unit 1,
From there, the address on the optical disk where the corresponding map information is stored is sent to the optical disk device 3, and the optical disk device 3 outputs the corresponding image information to the output information switching section 5. At this time, since the output information switching unit 5 is specified to output image information,
It is written as map or image information corresponding to the Y address and displayed on the display 7.

Next, when displaying symbol information, the X and Y addresses are input to the symbol and attribute information storage address calculation section 2, from which the address where the corresponding symbol is stored is calculated, and the symbol and drawing number output section 4 is output. At this time,
Since the symbol and drawing number output section 4 is designated to output symbols, the symbol to be displayed on the output information switching section 5 and the address in the frame memory 6 where the symbol is placed are output.

Furthermore, since the output information switching section 5 is designated to output symbols, symbols corresponding to the X and Y addresses are written into the frame memory 6 and displayed on the display 7 while being superimposed on the map.

Next, if you want to display the drawing that is the attribute information of the symbol,
Specify any symbol you want to search for with the pointer on the screen.

This results in the presence of the symbol X.

The Y address is input manually to the symbol and attribute information storage address calculation unit 2, from which the address where the corresponding symbol is stored is calculated and output to the symbol and drawing number output unit 4.

At this time, since the symbol and drawing number output section 4 is designated to output attribute information, the drawing number, which is the attribute information, is output to the image storage address calculation section 1. From there, the address on the optical disk where the corresponding drawing is stored is sent to the optical disk device 3, and after that, the drawing, which is the attribute information of the symbol, is displayed on the display 7 in the same manner as for map information. .

In other words, the map search device of the present invention registers drawings as image information as symbol attribute information, and when any symbol displayed on the display is specified, the map search device of the present invention searches for the drawing that is the attribute information of that symbol from among all drawings. It has an extraction means and displays the extracted drawings on the display instead of map information.

Note that the drawing is not limited to a floor plan of a building, but may be any image information such as an exterior view. In addition to alphabetical characters, numbers, etc., the symbols to be superimposed on the map may be any symbols registered as external characters. For example, it may be a pattern of 20×20 dots created in advance manually.

DETAILED DESCRIPTION OF THE INVENTION As described above, the present invention provides a means for registering drawings as image information as symbol attribute information and specifying any symbol displayed on a display, and a means for specifying an arbitrary symbol displayed on a display, and a means for registering drawings as attribute information of the symbol in all drawings. By having a means of extracting from the drawings and a function of displaying the extracted drawings on the display, it is possible to specify the corresponding symbol when information related to the displayed symbol is registered as a drawing. This simple operation has the effect of allowing related drawings to be displayed without inputting drawing numbers.
