Abstract

PURPOSE:To register attribute data correctly and in a short time by providing a function reading character strings and bar codes on paper by an OCR and a bar code reader and registering character data as attribute data. CONSTITUTION:In the attribute registration of a CAD, the character strings read from an OCR (optical character reader) 2 and the character data read from a bar code reader 3 are registered as attribute data and composed for prescribed portions on an object drawing or in the drawing. The character strings on paper is read by the OCR 2 to be used as an input device and they are converted from raster data to character data. The converted character data is transmitted to a terminal 1 using a line 102. The transmitted data is registered as attribute data for the drawing prepared by the CAD soft of the terminal 1. Next, a form 4 in which the name of a maker, the type No. of the maker and drawing No. are entered at prescribed positions is read by a sheet of OCR 2.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic reading system for CAD attribute registration, and in particular, a CAD attribute that requires registration of attribute data at a predetermined location where an attribute such as a drawing or a part on the drawing is written. Automatic reading system for registration

[0002]

2. Description of the Related Art In a conventional CAD attribute function, a character string is keyed in or a character data file stored on a disk is used to write a CAD drawing or an attribute such as a part on the drawing to a predetermined location. I was registering attribute data.

[0003]

In the attribute function of CAD, as a method of registering attributes as character data for a CAD drawing or a part on the drawing, a method of key inputting character data, or a method of recording data on a disk is used. Since there is only a method of inputting from character data stored in a file, the conventional CAD system has a problem that the operator has to key in a character already written on the paper or the like.

[0004]

The automatic reading system in the CAD attribute data registration function of the present invention is an OCR (optical character reading device) for CAD attribute registration.
The character string read from the character string and the character data read from the barcode reader are registered as attribute data with respect to the target drawing or a predetermined portion in the drawing.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

First, various data flows on the drawing will be described. The OCR2 used as an input device reads a character string on the paper surface and converts the raster data into character data. The converted character data is the line 102
To send to terminal 1. The transmitted data is registered as attribute data for the drawing created by the CAD software of the terminal 1.

Next, as an embodiment, a procedure for registering attribute data of a maker name, a maker model number, and a drawing number in a drawing created by CAD software will be described.

First, a drawing is created by the CAD software of the terminal 1, and a maker name, a maker model number and a drawing number are defined as attribute items. Next, one sheet of paper 4 on which the manufacturer name, manufacturer model number and drawing number are written in predetermined positions
Read with CR2. It is assumed that a character example is written on this sheet 4 in the format of Table 1 for each record. In addition, ":" (colon) is used as a delimiter between the attribute item name and the attribute data, and ";" (semi-colon) is used as the end character of the attribute data.

[0010]

[Table 1]

The read character string is converted into character data in the format shown in Table 2 on the OCR2.

[0012]

[Table 2]

Table 3 shows an example of the converted data.

[0014]

[Table 3]

The converted character data is sent to the line 1
It is transmitted to the terminal 1 via 02. The transmitted data is read by the CAD software of the terminal 1. The read data is divided into records by the end character ";" (semicolon) of the attribute data. Next, refer to one of the divided records, judge the character string up to ":" (colon) as an attribute item, and check if there is the same item as the attribute item set in advance in the CAD software. . If the same item exists, the attribute data of the attribute item in which the data between the delimiter ":" (colon) between the attribute item of the sent data and the attribute data and the end character ";" (semicolon) of the attribute data is checked Register as. This process is continued until the end of the transmitted data, and the attribute data is registered for each attribute item on the drawing. In the example of FIG. 1, the attribute data of Table 4 is registered.

[0016]

[Table 4]

Next, as another embodiment, a procedure for registering the part number, the part name, and the attribute data of the material as the part-related information with respect to the part on the drawing created by CAD will be described.

First, a drawing is created as shown in FIG. 2 by the CAD software of the terminal A shown in FIG. 1, and a part number as an attribute item,
Define the product name and material. Next, CAD for each part
In the group function of "011", "012" and "01", the part number is set as the group name for each part
Group by the name "3".

Next, the OCR of the input device A reads one sheet of paper B in which a part number, a product name, and a material are written in predetermined positions as part information. On this paper B, a character string is written in the format of Table 5 for each record. In addition, ":" (colon) as a delimiter of attribute data and ";" (semi-colon) as a delimiter of record are written in advance.

[0020]

[Table 5]

The read character string is shown in Table 6 on the OCR.
Converted as character data in the format.

[0022]

[Table 6]

Table 7 shows an example of the converted data.

[0024]

[Table 7]

The converted character data is transmitted to the terminal A via the line A. The transmitted data is read by the CAD software of the terminal 1. The data up to the first ":" in one record of the read data is determined to be the part number, and it is checked whether there is the same number as the group number preset in the CAD software. If there is the same number, it is registered as attribute data of the part number for the group of that number. Next, the data between ":" and ";" next to the transmitted data is registered as the attribute data of the product name. Similarly, the attribute data of the next material is registered. Further, referring to the next record, the same processing is continued until the end of the transmitted data, and the attribute data corresponding to each attribute item is registered for each part (group) on the drawing. In the example of FIG. 2, the attribute data of Table 8 will be registered.

[0026]

[Table 8]

[0027]

As described above, the present invention has a function of reading a character string and a bar code on a paper surface by an OCR and a bar code reader and registering attribute data for a CAD drawing and a part on the drawing. Since it is provided, there is an effect that it has a function of registering attribute data with respect to a CAD drawing, a part on the drawing, and the like more accurately and in a shorter time than the conventional human keyboard input.
