Abstract

PURPOSE:To correct easily a diagram and to improve the accuracy of the diagram by converting a topographical chart out of information to be processed by a computer into run length vector data and a route chart into vector data and storing these data in respective files. CONSTITUTION:The topographic chart of a town plan is read out an image reader 1A such as a facsimile device and inputted to an electronic computer 1B. The data are rapidly converted into run length data having the continuous length of a ''0''/''1'' data string and starting point position information by a processor 1G for binary pictures. A piping route out of distribution line equipment information is inputted to the computer 1B as digital data by a digitizer device 1F. Route chart vector data 1a and topographic chart run length vector data 1b which are to be processed by the computer are stored in a magnetic disc device 1C respectively. After information retrieval, the output of the route chart is displayed and printed out by synthesizing and editing two kinds of data. Thus, the correction of the diagram can be easily attained and the accuracy can be improved.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention is an underground electric power distribution system that mechanizes the creation of underground power distribution line drawings using a computer, a fax machine for inputting topographical drawings, and an electrostatic plotter for outputting line drawings. This invention relates to an automatic drawing device for drawing distribution lines.

[Prior art]

Conventionally, underground railway drawings were created at a rate of 1:11,500.
After the completion of the burying work, one person manually writes the underground distribution line piping route map on a topographic map of A2 size or higher, and the original version of the drawing is saved and managed on microfilm. Saved. In addition to the above-mentioned manual drawing method, there is a conventional automatic drawing device of this type shown in FIG. 1, which uses electronic seven-eye ring technology to store one drawn drawing on a magnetic disk or the like.

In Figure 1: 1hts, image reader device.

The IB is an electronic computer such as a CPU, the IC is a magnetic disk device, the ID is a graph ink display device such as a CRT, and 1E is an electrostatic plotter.The operation will be explained below based on the system configuration diagram in Figure 1. .

The underground power distribution line drawings, which were created by thieves manually, were read using the image reader device IA and then using the electronic computer IB.

Image information is processed, data is compressed, and stored in the magnetic disk device IC. This stored track drawing data is searched, and the corresponding drawing is displayed on the graphic display device ID, and is enlarged or reduced as the case requires. Furthermore, if a large drawing of the same size as the original drawing is required, the drawing is printed out on the electrostatic plotter IE. Obtained by scanning and sampling black and white images into the drawing information input to the computer 2
Image data that converts value image data into a code string of "0", and is compressed and expanded by computer processing.

Memory 3 display, printout, etc. are all based on the above image data.

Conventional automatic drawing equipment is configured as described above, so it cannot be said that it is a mechanization of drawing work because it only reads the completed underground distribution line diagram with an image reader device.
Because all the information processed by the FFC computer is based on the image data of 1#:''0#.

Accuracy during cutting of the drawing became a problem, and '! F7' (The topographic map and track map data were stored in the same file, so it was difficult to modify the drawings due to changes in the power distribution equipment.

[Summary of the invention]

The present invention was made in order to solve the above-mentioned drawbacks of the conventional method.The topographic map and the railway map are stored in separate files, and the information to be processed by computer is the topographic map, run-length vector data based on image data, By converting track diagrams into vector data, it becomes easy to correct the 5-drawing size and modify drawings due to changes in track equipment. is intended to provide.

[Embodiments of the invention]

Hereinafter, one embodiment of this invention will be explained based on FIG. i?
, 8A. In FIG. 2, IA, IB, and IC.

ID and IE indicate the same or corresponding parts as the same reference numerals in FIG.

1a is railway map vector data, 1b is topographic map run-leg spectrum data, IF+-[digitizer device, and IG is a processor dedicated to binary images.

Let me briefly explain the operation. Read the urban topographic map with an image reader device 1A such as a 7Ax device.

Input into computer 1B. The input image data is black and white binary image information, but it is quickly converted to length data containing the continuous length of p"0"1" data string and starting point position information by the binary image dedicated processor IG. The distribution line equipment information is inputted to the slave computer IB using the digitizer device 1F with piping routes as digital data.The railway map vector data 1a and the topographic map run length vector data 1b, which are subject to electronic computer processing, are stored on the i-disk. They are each stored in the device 1C.After the information search, the output of the corresponding track diagram is synthesized and edited by combining the two types of data, and then displayed and printed.

The above-mentioned topographical map inputted by an image reader device IA such as a fax machine can be corrected in size and enlarged/reduced at any magnification as run-length vector data, making it possible to create a high-precision drawing.

〔Effect of the invention〕

As described above, according to the present invention, an expensive and large image reader device is not used, and a relatively small general-purpose device such as a fax machine is provided as a drawing input device, so image data is converted into run-length vector data. This method has the effect of obtaining an automatic drawing device for underground power distribution line drawings with very high accuracy.
