[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character data compression display device for inputting and displaying character data in a table or list having a limited display area.

[0002]

2. Description of the Related Art A conventional character data compression display device replaces full-width characters (symbols, alphabets, numbers, and katakana) in input character data with half-width characters, adjusts character spacing, and changes fonts. To perform compression display of character data. FIG. 10 is a functional block diagram showing a conventional character data compression display device disclosed in Japanese Patent Application Laid-Open No. 2-105924. In the figure, 1 is a keyboard for inputting character data, 2 is an external storage device storing character data, 3 is composed of an input text length calculation unit 4, a display availability determination unit 5, and an input text conversion unit 6. The display control unit 7 is a CRT for displaying the converted character data.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a character data compression display device according to Embodiment 1 of the present invention. In FIG. 1, reference numeral 101 denotes a character data memory which is an external storage device. Reference numeral 102 denotes a character data length calculation unit 103 that calculates the character data length of the input character data, a display availability determination unit 104 that compares the character data length with the display restriction data length, and an abbreviation dictionary of the abbreviation dictionary data memory 109. A dictionary search unit 105 for referring to data and searching for a replaceable partial character string, and a dictionary search unit 10
5 is a character data compression unit that includes a character data replacement unit 106 that replaces the partial character string searched for in step 5 with an abbreviated character string. A display unit 107 displays the character data compressed by the character data compression unit 106 on the CRT 108. An abbreviation dictionary data memory 109 describes the correspondence between the character strings and the abbreviation character strings.

Next, the operation will be described. FIG. 2 is a flowchart illustrating the operation of the character data compression unit 102 of FIG. The character data compression unit 102 reads the character data 101 stored in the external storage device (step 201), and the character data calculation unit 103 calculates the character data length of the character data (step 202). The calculation method is the same as the operation of the conventional input text length calculation unit 4 described with reference to FIG.

Next, the display data determination unit 104 compares the character data length calculated in step 202 with the display restriction data length (step 203). If the character data length is smaller than the display limit data length, that is, if display is possible, the data is passed to the display unit 107 (step 208).

If the character data length is longer than the limit data length, that is, if display is impossible, the dictionary search unit 105 searches the abbreviation dictionary data memory 109 for abbreviation dictionary data (step 204). Search is abbreviated dictionary data memory 1
The search is performed by searching for a partial character string in the character data from a group of words in 09. As a result of the search, if there is a word that matches the partial character string (step 205), the abbreviation character string and the partial character string corresponding to the word are replaced by the character data replacement unit 1.
06, the replacement character data is compressed (step 20).
6).

The character data compressed in step 206 is judged again by the display permission / inhibition judging unit 104. If the character data is larger than the display limit data length, steps 204 to 206 are repeated until the character data becomes smaller than the display limit data length, and display is possible. Then, the data is passed to the display unit 107 (step 208).

If there is no partial character string that can be replaced with an abbreviation character string in the character data in step 205, the character data cannot be further compressed, and the part exceeding the display limit data length of the character data is cut out (step 205). 20
7) Pass the data to the display unit 107 (step 20)
8).

FIG. 3 shows how character string data is compressed. In FIG. 3, reference numeral 301 denotes data input to the abbreviation dictionary. First, character data 302
Is input (step 201). 24 full-width characters
Since a character has been input, the character data length is 48 (step 202). If the display limit data length is 50 (step 203), the data is displayed without compression (step 20).
8).

If the display limit data length is 40, the character data length of the character data 302 exceeds the display limit data length (step 203), so that abbreviation dictionary data is searched (step 204). Here, since the partial character string "stem leak off valve" matches the abbreviation dictionary data "SL off valve" (step 205), the "stem leak off valve" is replaced with the abbreviation character string "SL off valve", and the character data 303 is created (step 206). Since the character data length of the character data 303 is 40, which is the same as the display restriction data length, the character data is passed to the display unit 107 and displayed on the CRT 108 (steps 203 and 208).

If the display restriction data length is 30, the display restriction data length is smaller than the character data length of the character data 303 (step 203), so that the partial character string "ground steam" in the character data 303 is abbreviated to the character string " A replacement character string 304 is created with “GS” (steps 204 to 206). Although the character data length of the character data 304 is 32, since the display limit data length is larger than 30, the steps 204 to 206 are further performed, and the partial character string “large torque operation” is replaced with the abbreviation character string “large torque”. The data 305 is created. Since the character data 305 has a character data length of 28, which is smaller than the display restriction data length of 30, the character data is transferred to the display unit 107 and displayed on the CRT 108 (steps 203 and 208).

Thus, by replacing the partial character string in the character data with the abbreviation character string, the character data can be compressed and displayed, and moreover, the character data which is unified into full-width characters and has good appearance can be displayed. . Further, it is possible to increase the compression ratio as compared with the case where full-width characters are replaced with half-width characters.

Embodiment 2 FIG. In the first embodiment, the case where the display character data is passed from the character data compression unit 102 to the display unit 107 has been described. In the second embodiment,
As shown in FIG. 4, a display data storage unit 401 is provided in the character data compression unit 102, and display character data is stored in a display character data memory 402 which is an external storage device.
The display unit 107 reads out the display character data, and
The display on the display 108 allows the data compression unit 102 and the display unit 107 to operate independently.

By storing the display character data in the display character data memory 402, which is an external storage device, it is not necessary to execute the data compression processing every time the display unit 107 displays the data, thereby shortening the data display processing. be able to. When the character data in the character data memory 101 has been changed, the display character data is created using the data compression unit 102 again.

Embodiment 3 In the second embodiment, the case where the display character data is stored in the display character data memory 402 which is the external storage device by the display data storage unit 401 has been described. In the third embodiment, however, as shown in FIG. By providing the device 501, the data of the character data memory 101 is searched from the display character data, and the CRT is searched.
502 is displayed.

By providing the search device 501, character data and display character data can be the same data, and the display character data created by the character data compression unit 102 can be replaced with character data. As a result, the data storage area of the external storage device can be saved, and data management can be facilitated.

Embodiment 4 In the first embodiment, a case has been described in which, when there is no partial character string that matches the abbreviation dictionary data in the abbreviation dictionary data memory 109, character data of a portion exceeding the display limit data length is cut. Then, as shown in FIG.
To display character data exceeding the display limit data length
By providing the RT 602 and the dictionary input unit 603 for adding data to the abbreviation dictionary data, data compression can be performed even on character data exceeding the display restriction data length.

FIG. 7 is a flowchart for explaining the operation of the fourth embodiment. If there is no partial character string matching the word in the dictionary data when the abbreviation dictionary data is searched in step 205, the screen for inputting new abbreviation data is displayed on the screen C
The information is displayed on the RT 602, and words and abbreviations are input using the input device 601 (step 701). At step 206,
In step 701, the character data is compressed by replacing the partial character string with the newly input abbreviation data.

Embodiment 5 In the first embodiment, the case where the character data replacing unit automatically replaces the partial character string with the abbreviated character string has been described. However, in the fifth embodiment, as shown in FIG. Provided,
A plurality of display candidate data created by the display candidate creation unit 801 are displayed on the CRT 602, and the input device 601
By selecting the data to be compressed, it is possible to perform data compression display in consideration of human judgment.

FIG. 9 shows an example of display candidate data. When the input character data 902 is compressed using the abbreviation dictionary data 901, seven types of display character data of character data 903 to 909 can be created. If the display limit data length is 50, character data 90
Seven types of character data from 3 to 909 are displayed on the CRT 602. If the display limit data length is 40, four types of character data, character data 906 to 909, are displayed on the CRT 602 as display candidate data. From the data displayed on the CRT 602, input desired data to the input device 601.
The display character data is created by selecting with. Thus, when displaying character data in the table, the character data can be displayed in a form that is combined with the character data in the preceding and succeeding columns in the table.

[0034]

As described above, according to the present invention, character data can be compressed and displayed on a table or a list having a limited display area without changing the size of the display area. In addition, since processing for converting full-width characters to half-width characters and processing for changing character spacing and font are not performed, character data in tables and lists can be displayed uniformly. Further, the compression ratio can be improved.

Since a large number of people are involved in plant design, it is necessary to accurately communicate specifications and use unified abbreviations. However, it is necessary to provide abbreviation dictionary data to automatically replace character strings. Therefore, when humans input character data, abbreviations do not need to be used, and the specifications can be conveyed accurately.

Since the display data storage section is provided to store the display character data in the external storage device, the data compression section and the display section operate independently, and the data display processing can be shortened.

Further, a search device is provided so that character data and display character data can be the same data, so that the data storage area of the external storage device can be saved and data management can be facilitated.

Since a dictionary input unit is provided so that abbreviation data can be added, data compression can be performed no matter what character data is input.

Further, by providing a display candidate creating section and adding human judgment, a partial character string to be compressed can be freely selected.
