Abstract

PURPOSE:To attain high speed when an area is displayed and outputted by reading the information in 1/4 drawing units, 1/4 facility drawing units or at plural times when the information registered at a data base is outputted. CONSTITUTION:A map and a facility drawing are inputted from an image reader 6. Based on the control of a central arithmetic processing unit 1, the vectorization and recognition of a drawing are executed by an image processor 7 and the recognition of the symbol, line and character of a facility drawing is executed by an image OCR device 8 based on the control of the device 1. The correspondence is executed based on the facility information developed from an MT device 3 to a disk device 4 beforehand and facility drawing information is prepared. Thereafter, concerning the map, each one drawing area is divided into 4 equally, into a 1/4 drawing unit finally, and the data such as a road and a house are registered to the data base at the device 4. In the same way, each one facility drawing area is divided into 4 equally and the data such as an electric pole and an electric wire are registered.

[Problem to be solved by the invention]

Since the conventional map information input/display device is configured as described above, it is a graphic CRT 9 e.

The units displayed in 10e and lle can only display multiple areas per drawing, and when displaying a part of the drawing (for example, when displaying 174 drawings), from within the database area of one drawing. It takes an hour to extract a 1/4 part, and when displaying a part that includes the drawing boundary, it is necessary to display a drawing that is multiple times larger than one drawing, which takes time and requires unnecessary processing. There were some issues, such as displaying all the details.

In addition, as an approximation technique, see Mitsubishi Electric Technical Report V o 1.

This invention was made in order to solve the above-mentioned problems, and an object of the present invention is to obtain a map information input/display device that can display map information in units of 1/4 of one drawing and in multiples thereof. .

[Means for Solving Problems] The map information input and display device according to the present invention divides the entire existing drawings such as equipment drawings and topographical drawings into four equal parts,
This system is equipped with a disk device that divides and stores data into four units, and a graphic CRT that displays data in quarter units or multiples thereof when searching and displaying data stored in this disk device.

[Effect]

The disk device according to the present invention divides the input map information or equipment drawing information into quarters for each drawing,
When storing this data in the database of a disk device and searching and displaying it, this 1/4 unit or multiples thereof can be directly retrieved from the disk device and used as a graphic C.
The data is transferred to the RT and combined horizontally to display all data in the specified area on the graphic CRT through one data search.

In addition, applicable drawings include applications to power distribution equipment drawings, water and sewage, gas communication line equipment drawings, residential maps, and the like.

〔Effect of the invention〕

As described above, according to the present invention, the database registration unit of map information and equipment drawing information is divided from the conventional existing drawing of one drawing into 1/4 area, and is divided into 174 drawing units or 1/4 equipment drawing. When dividing the information into units and outputting the information registered in this database, it is configured to be read in 1/4 drawing units, 1/4 equipment drawing units, or multiple times thereof, so it is faster to display and output areas. In addition, when displaying an area at the boundary of a drawing, there is no need to display all related drawings, which speeds up the display, and only the area around the display target can be displayed, making it possible to display the drawing without any waste. It has the effect of becoming.

Further, by reading out from the database in combination of 1/4 drawing units or 1/4 equipment drawing units, there is an effect that it is easy to edit and output a single drawing that is different from existing drawings.
