Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a map management device that expresses facility information on a map and manages the facilities.

(Prior Art) Conventionally, in a map management device for managing facility information using a map, all the map information (that is, facility information and blank map information used as a background map) is converted into vector information by a vector such as a digitizer. The configuration was such that information was input using an input device and stored and managed collectively. In the map management device, an operation is performed in which a vector pattern representing the vector information that is collectively stored and managed is drawn in the frame memory. Then, the map image drawn in the frame memory is displayed on the screen.

(Problems to be Solved by the Invention) In the conventional map management device described above, all map information (facility information and blank map information) had to be input as vector information using a vector input device such as a digitizer. The problem is that it takes a lot of time and is not practical.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a map management device that can input map information used for facility management in a short time.

[Structure of the Invention] (Means for Solving the Problems) The present invention is characterized in that among the map information provided for facility management, blank map information used as a background map has a significantly smaller amount of changes than facility information. Focusing on this, we created a configuration in which blank map information is input as an image, and facility information that changes frequently is input in vector information as before, and according to this vector information, the corresponding facility information is framed in a vector pattern. draw to memory,
This is characterized in that it can be superimposed on a blank map image on the frame memory.

(Function) According to the above configuration, when facility information is managed on a map, all map information is not input as vector information, but blank maps are input using the first input means (such as an image scanner). (image input device) as image information.

This input of image information can be performed in a shorter time with a simpler operation than inputting vector information using the second input means (vector input device such as a digitizer), so the input time can be shortened. Moreover, unlike facilities that are input as vector information, blank maps are used only as background maps, are not subject to management, and have a significantly small amount of changes, giving them meaning like information on managed facilities. Since it is not necessary, there is no problem even if it is input as image information.

(Embodiment) FIG. 1 shows a block configuration of a map management device according to an embodiment of the present invention. In the figure, reference numeral 11 denotes an image input device such as an image scanner for inputting an image such as a blank map of a facility other than the facility used only as a background image in order to manage facility information using a map; Reference numeral 12 denotes an image storage device for storing and managing images such as blank maps input from an image input device. Reference numeral 13 denotes a vector input device such as a digitizer for inputting information on facilities to be managed as vector information, and reference numeral 14 denotes a vector storage device for storing and managing vector information input from the vector input device.

15 is a display monitor used for displaying maps for managing facility information, and 1B is a frame memory in which images for display are stored. , 17 is a display control device for displaying the image stored in the frame memory 16 on the display monitor 15, and 18 is an output of an electrostatic plotter or the like for outputting the image stored in the frame memory 1B onto paper. It is a device. 19 is an address controller that reads image information from the image storage device 5f12 and determines the writing position when writing to the frame memory 16 by DMA (direct memory access) transfer; 20 reads vector information from the vector storage device 14 and determines the writing position; This is a vector drawing device that draws a vector pattern indicated by information on a frame memory 16.

Next, the operation of the configuration shown in FIG. 1 will be explained.

First, for a blank map or the like that is used only as a background image and is not to be managed, an image thereof is input using the image input device 11. The image of this blank map etc. is
The image is saved in the image storage device 12. On the other hand, information on facilities and the like to be managed is input as vector information using the vector input device i3. Vector information representing this facility etc. is stored in the vector storage device 14.

An image such as a blank map stored in the image storage device 12 is written to the frame memory 16 under the control of the address controller 19. On the other hand, vector information representing facilities and the like stored in the vector storage device 14 is read out by a vector drawing device 20 implemented by, for example, a CPU. In accordance with the vector information read from the vector storage device 14, the vector drawing device 20 draws the facilities indicated by the information in the frame memory 16 in a vector pattern. As a result, an image such as a blank map and a vector pattern representing a facility etc. are superimposed on the frame memory 16. The blank map and facility information written on the frame memory 16 are displayed in a superimposed state on the display monitor 15 under the control of the display control device 17. That is, a map representing the facility is displayed on the display monitor 15,
Used for facility management, etc. In addition, the map displayed on the display monitor 15 (representing the facility) can be
The image is output onto paper by an output device 18 such as an electrostatic plotter.

The above is an explanation of the map management device, but it is possible to
The present invention can also be applied to document management and drawing management by replacing photos with text and drawings for facilities.

[Effects of the Invention] As detailed above, according to the present invention, when managing facilities etc. on a map, instead of inputting all information as vector information, which takes time to input, it is possible to manage facilities only as a background map. For blank maps that are not used, are not subject to management, and have a very small amount of changes, we input images that require less input time, and superimpose the image and vector pattern on the frame memory. Map information used for facility management can be input in a short time. Moreover,
Unlike facilities that are input as vector information, blank maps are not subject to management as described above, the amount of change is extremely small, and there is no need to give them meaning like information on facilities that are subject to management. There is no problem even if you input it as information.
