Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application field] The present invention relates to an automatic drawing method of a civil engineering survey map, and in particular to an automatic drafting machine for various structures such as gutters, road cross-sections, buildings, etc. ]) Is related to a method for automatically drawing a civil engineering survey map for creating a civil engineering survey map at a location including the same.

[Prior art and its problems] Conventionally, an automatic drafting machine is configured by connecting a drawing device and a computer equipped with a display device and a keyboard. Performs arithmetic processing and issues a predetermined instruction.
According to this, drawing was performed by an automatic drawing apparatus. But,
If the civil engineering survey data is simply land surveying (topographic data), it is easy to draw a survey map through a computer, but the survey data can be converted to survey data different from simple topographic data such as special structures. In order to draw a drawing based on the special structure, data of a special structure is input to a computer and drawn on a survey map that has already been drawn.

In the conventional drawing method for drawing such a special structure, the input of the structure data must be given as the movement amount of the pen of the drawing apparatus, which is very troublesome.
Also, the structure data input to the computer is only displayed numerically on the display, and until the drawing is performed by the drawing device, the correctness and error of the size and arrangement of the structure figure cannot be confirmed graphically and visually. Unless it is output to a drawing device and a test copy is made, it cannot be determined whether or not the figure is correct.

An object of the present invention is to provide an automatic civil engineering survey map drawing method for creating a civil engineering survey map at a location including a special structure that solves the above-mentioned problem.

[Means for Solving the Problem] Input means for inputting civil engineering survey data including a special structure, conversion means for converting civil survey data including the special structure into graphic data, and storage means for storing graphic data Means for converting the input civil engineering survey data or the graphic data output from the storage means into a graphic pattern, a display means for displaying the graphic pattern, and selecting and selecting the graphic pattern displayed on the display means. Selection processing means for processing the selected graphic pattern; comparison / registration means for comparing the selected processed graphic pattern with the graphic data stored in the storage means for registration; and outputting the selected processed graphic pattern. And means.

[Operation] Accordingly, the input civil engineering survey data including the special structure is converted into graphic data by the converting means, and the converted graphic data is graphically displayed on the display as a graphic pattern. Then, it can be visually determined whether or not the figure is the target figure.

Further, since the special structure thus drawn can be stored in the storage means as graphic data, it can be used for overlapping drawing.

Embodiment An embodiment according to the present invention will be described below with reference to the drawings.

In FIG. 1A, an automatic drafting machine S used in the present method example is shown.
Are a microcomputer 1, a keyboard input device a1 as input means a1, an auxiliary input device a2 such as a digitizer,
It comprises a storage device c, a display device g, a drawing device h, and the like.

The microcomputer 1 in this example is a well-known microcomputer, and includes a CPU (Central Processing Unit), RAM, and RO.
It is composed of M etc. A program for controlling the CPU is written in the ROM, and the CPU reads necessary data from the input means a according to the program,
It performs arithmetic processing while transmitting and receiving data to and from, and outputs the result. A keyboard input device a1 and an auxiliary input device a2 such as a digitizer are connected as the input means a in the present embodiment, and predetermined civil engineering survey data can be input to the computer 1 by the input means a.

Further, the microcomputer 1 of the present embodiment can access a storage device c such as a floppy disk as a storage means, and stores data to be stored and stored in the storage device c.

Further, a graphic display device g is connected to the microcomputer 1 of the present embodiment as a display device so that input data from the keyboard input device a1 and the auxiliary input device a2 such as a digitizer can be graphically displayed on the graphic display device g. It has become.

Further, the microcomputer 1 is connected to a drawing device h, and the drawing device h operates based on an output command from the microcomputer 1.

More specifically, civil engineering survey data including a special structure is input by the input means a.

The input of civil engineering survey data including special structures is to input the entire structure to be plotted or the elements that make up the structure,
Using the graphic display on the display screen, enter the numerical values while checking the shape. As will be described later, the entire structure or the elements constituting the structure can be identified by the structure name or the element name, and the result is recorded in the storage device c as a data file. The operation is further simplified by directly reading and inputting from the design drawing of the structure by the digitizer a2 as another input means a.

The input civil engineering survey data is converted into graphic data by the graphic data converting means b. Next, in this example, the converted graphic data is temporarily stored in the storage device c. At the same time, it is displayed on the graphic display device g as a graphic pattern by the graphic pattern conversion means d. On the other hand, when a conventional graphic pattern is used, graphic data output from the storage device c is converted into a graphic pattern by the graphic pattern conversion means d, and the graphic pattern is displayed on the graphic display device g. This is to take advantage of this. Next, the graphic pattern displayed on the graphic display device g is selected, and the selected graphic pattern is processed. Selection and processing of a graphic pattern is performed by inputting from the keyboard a1.

In this example, the graphic pattern that has been selectively processed is displayed on the graphic display device g, and is compared with the graphic data stored in the storage means by the comparing means e. The graphic pattern compared by the comparing means e is displayed on the graphic display device g, and the displayed graphic pattern is sent to the selection processing means f by the keyboard a1.
Output by instructing from. By such a comparing means e, a newly input graphic pattern, a stored graphic pattern, and a graphic pattern can be identified by a combination thereof, and the difference between the graphic patterns and the graphic pattern obtained by converting the civil engineering survey data can be identified. The difference from the pattern can be confirmed. Output for drawing is performed by the drawing device h. A known device can be used as the drawing device h. If the pattern is not stored in the storage unit after being compared by the comparison unit, it is stored in the storage unit.

FIG. 1B is a flowchart. When the program of the microcomputer 1 is started, the microcomputer 1 serving as the processing control unit reads the graphic data from the storage device c, reads the information such as the index of the graphic data, etc. in step 10. Is started, and the index and information of the graphic data are displayed on the graphic display device g.

In step 20, the graphic display device g
The user selects a predetermined graphic pattern from the graphic data by using the keyboard a1 by using the graphic data index displayed in (1).

If an arbitrary graphic pattern is selected in step 20, the graphic pattern is read from the storage device in step 40, and the process proceeds to step 60. On the other hand, if a graphic pattern other than the graphic data to be displayed (graphic data stored in the storage device) is desired, step 50
, A target graphic pattern is input via the keyboard a1, and the process proceeds to step S60. The graphic pattern input in step 50 is displayed on the graphic display device g. In step 60, whether the graphic pattern displayed on the graphic display device g is the target or not,
The procedure differs depending on whether a partial correction is required, whether the same pattern requires a plurality of or different patterns, and whether the position and orientation are correct with respect to the XY coordinate system. come. That is, if the figure is completely different from the target figure, or if another or the same figure pattern is required, the comparison is made in step 70 and the process returns to step 20 by inputting the keyboard a1. In addition, if the figure pattern is XY
When moving or partially correcting or processing the coordinate system, the keyboard a1 and the auxiliary input device a2 are used to perform movement and correction. This state is the graphic display device g
Will be displayed. When the target graphic pattern is obtained in step 60 and displayed on the graphic display device g, if necessary, this graphic pattern is registered in the storage section c and output to the drawing device h in step 80 to draw the graphic pattern. Let By repeating the processing shown in this flowchart, special structures can be drawn one after another. In this example, the comparison means e can identify a figure pattern based on a processing result including a newly input figure pattern, a stored figure pattern, a combination thereof, and the like, and confirm a difference between the figure patterns. can do.

As a concrete example, FIG. 2 shows a civil engineering survey map created by the method shown in the above embodiment, and it is assumed that the figure pattern shown in FIG. 2A is already stored in the storage device c. To draw FIG. 2B, the graphic data of FIG. 2A is read from the storage device c, converted into a graphic pattern by the graphic pattern conversion means d, and displayed on the display device g.
Next, in the selective processing means f, the graphic pattern of FIG. 2A is processed by inputting to the keyboard a1. In this example, since the upper portion X1-Y1 of the special structure is the same, the X1-Y1 portion is left and the other portions are deleted. Since these are always displayed on the display device g, this is performed while visually observing them. Then, the portions X2-Y2 and X3-Y3 are input by the keyboard a1 or the digitizer a2. At this time, the comparison unit e compares the newly input graphic pattern with the input graphic data, and it is possible to confirm whether or not the graphic pattern is correctly input. If the input is made correctly, select
An output command is issued from a1 to the drawing device h, and drawing is performed by the drawing device h.

As described above, at the stage of arranging the special structure and making the drawing, the necessary special structure or the element data of the special structure is called from the file from the already recorded special structure data group, and is displayed on the display screen. And moves, rotates, and combines each of the graphic patterns so that a target graphic is obtained.

The graphic pattern of the combined special structure is given a new name if necessary and recorded in the storage device as a data file.

[Effects of the Invention] As described above, according to the method of the present invention, the input data is graphically displayed on the graphic display device, so that the correctness of the graphic data can be visually confirmed before the operation of the drawing device. In addition, since data can be input with the input device while watching the graphic display of the graphic display device, there is no mistake in drawing. If a large number of graphic patterns are stored in the external storage device, input of duplicated data is omitted, and a target structure can be drawn by selecting a graphic pattern, thereby simplifying the drawing operation.
