Abstract

PURPOSE:To completely and surely register the images and the attribute data of many symbols contained in a maintenance drawing. CONSTITUTION:The symbols which are registered in a basic data base 1 constructed previously are collated with each symbol contained in a maintenance drawing. Then a list of the symbols and their corresponding attribute items is displayed when a relevant symbol is detected out of the base 1. The corresponding attribute data is inputted and registered into a maintenance drawing data base 12. In such a constitution, an operator can completely register many symbols and their corresponding attribute data into the base 1 just by selecting the symbols shown on a screen of a display device 6 and then inputting the attribute data to an attribute item list which is automatically shown to the selected symbol. Thus the reliability of the base 12 is improved.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a maintenance drawing management system for managing maintenance drawings using a computer.

0003

[Prior Art] Conventionally, in order to manage maintenance drawings using a computer and register attribute data of symbols on the drawings,
The operator searches and specifies the symbol on the maintenance drawing from the drawing displayed on a display device such as a CRT, and the attribute data for the specified symbol is created in advance in a database with a list of attribute data as code data. The method used was to first specify the correspondence between the symbol specified on the drawing displayed on the display device and the attribute data.

0004

[Problems to be Solved by the Invention] However, in such conventional maintenance drawing management systems, in order to register the attribute data of symbols on maintenance drawings, an operator has to input it as image information and display it on a display device. It is necessary to manually search for the symbol that you want to associate with attribute data from among the maintenance drawings that have been created and specify it on the screen.Furthermore, in order to register the attribute data to the specified symbol, it is necessary to create a database in advance. It is also necessary to correlate the drawings with a list of attribute data, which takes time to maintain and manage the drawings, and because it requires a lot of manual work, registration errors are likely to occur.

[0005] The present invention was made in view of the above-mentioned conventional problems, and in order to register the attribute data of each symbol on a maintenance drawing, symbols and corresponding attribute data item tables are created in a database. Without the operator having to search for the symbol of the input maintenance drawing, the computer side recognizes the symbol, displays the symbol in a display mode different from other parts, such as a flicker display, notifies the operator, and allows the operator to select it. Maintenance drawing management that simultaneously displays the item list of symbols and allows entry of attribute data, allowing operators to recognize symbols that require attribute data registration without overlooking them, and register the attribute data. The purpose is to provide a system.

[Configuration of the invention]

[0007]

[Means for Solving the Problems] The maintenance drawing management system of the present invention includes a symbol registration means for inputting symbols used in maintenance drawings as image data and creating a database, and a system for registering attribute data of each symbol. an item registration means for creating a database of common items necessary for the above, a basic database for registering image data input from the symbol registration means and item data input from the item registration means in correspondence, and a maintenance drawing management target. a drawing input means for inputting the drawing as image data;
a drawing search means for searching a drawing input by the drawing input means for a symbol identical to a symbol registered in the basic database; a drawing display means for displaying the drawing input by the drawing input means; and a drawing display means for displaying the drawing input by the drawing input means; When it is recognized that there is a symbol that is the same as a symbol registered in the basic database within a specific range on the drawing displayed on the display means, the display part of the symbol is displayed in a different manner from other parts. symbol identification display means; symbol selection means for inputting a selection signal for the symbol displayed by the symbol identification display means; item display means for displaying an item table corresponding to the same symbol in the display; item attribute data input means for registering attribute data for the item table displayed by the item display means; The maintenance drawing management database includes image data of a maintenance drawing, and a maintenance drawing management database that registers attribute data input by the item attribute data input means for each symbol included in the maintenance drawing.

[0008]

[Operation] In the maintenance drawing management system of the present invention, symbols used in maintenance drawings are inputted as image data by the symbol registration means, and are created into a database, and the common information necessary for registering attribute data of each symbol by the item registration means is provided. These items are made into a database, and these data are registered in the basic database in correspondence with each other.

In maintenance management of drawings, drawings to be managed for maintenance drawings are input as image data using a drawing input means, and from the input drawings, a symbol that is the same as a symbol registered in the basic database is searched by a drawing search means. The drawing is searched, and the drawing is further displayed by the drawing display means. When the symbol identification means recognizes that there is a symbol that is the same as a symbol registered in the basic database within a specific range on the drawing displayed on the drawing display means, the displayed part of the symbol is display in a different manner than the other parts.

When the symbol selection means inputs a selection signal to a symbol displayed by the symbol identification display means in a manner that allows it to be distinguished from other parts, the item display means selects a symbol for the selected symbol. Display the item list corresponding to the same symbol registered in the basic database.

[0011] Therefore, when the operator registers attribute data using the item attribute data input means for the item table displayed by the item display means, the attribute data is input into the maintenance drawing management database by the drawing input means. Image data of the maintenance drawing and item attribute data for each symbol included in this maintenance drawing are registered.

[0012] In this way, the system automatically searches for symbols for which attribute data should be registered and also displays an item list for that symbol, without the operator having to search for symbols for which attribute data should be registered. It is possible to build a maintenance drawing database by clarifying what item attribute data should be registered and registering symbol attribute data for each drawing without losing them.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be explained in detail below with reference to the drawings.

FIG. 1 is a block diagram showing the system configuration of an embodiment of the present invention, and includes a basic database in which image data of various symbols included in a maintenance drawing and attribute item data corresponding to each symbol are registered in correspondence with each other. 1
, a symbol registration section 2 for inputting symbols used in maintenance drawings as image data and registering them in the basic database 1, and a common item necessary for registering the attribute data of each symbol in the basic database 1. It also includes an item registration section 3 for registration.

As maintenance drawing database registration means, there is a drawing input section 4 such as an image scanner that inputs drawings to be managed as maintenance drawings as image data, and a drawing input section 4 inputted by the drawing input section 4 into the basic database 1. A drawing search unit 5 that searches for the same symbol as a registered symbol, and a drawing display unit 7 that displays the drawing input by the drawing input unit 4 on the CRT display device 6.
It is equipped with

Furthermore, when the drawing display section 7 recognizes that there is a symbol that is the same as a symbol registered in the basic database 1 within a specific range on the drawing displayed on the CRT display device 6, the symbol A symbol identification display unit 8 that displays a display part in a manner different from other parts, and a symbol such as a keyboard or mouse that inputs a selection signal to a symbol displayed on the CRT display device 6 by the symbol identification display unit 8. It is provided with a selection section 9 and an item display section 10 for displaying an item table corresponding to the same symbol registered in the basic database 1 for the symbol selected by the symbol selection section 9.

Furthermore, an item attribute data input section 11 registers attribute data for the item table displayed by the item display section 10, image data of the maintenance drawing inputted by the drawing input section 4, and image data of the maintenance drawing inputted by the drawing input section 4. A maintenance drawing management database 12 is provided in which attribute data input by an item attribute data input section 11 for each symbol included in a drawing is registered.

Next, the operation of the maintenance drawing management system having the above configuration will be explained.

First, in order to construct the basic database 1, image data of various symbols are registered in the symbol registration section 2, and a list of common items necessary for inputting attribute data to each symbol is registered in the item registration section 3. Register by.

FIG. 2 shows that a symbol 21 registered in the CRT display device 6 by the symbol registration section 2 has a symbol name 2.
2 is shown as a list display example. Further, FIG. 3 shows an example in which the item registration unit 3 displays a necessary item list 24 in the symbol name 22.

In constructing the preservation drawing database 12, the drawings to be preserved are input as image data by the drawing input section 4, and the drawings 31 input by the drawing input section 4 are displayed by the drawing display section 7 as shown in FIG. CRT
It is displayed on the display device 6, and at the same time, the drawing search unit 5 searches the input maintenance drawing to see if there is any symbol data that is the same as the symbol data registered in the basic database 1, and to find out its position.

From the drawing displayed on the CRT display device 6,
By moving the symbol search window 32 within a certain range, the symbols matched by the drawing search section 5 are flicker displayed on the CRT display device 6 by the symbol identification display section 8.

Therefore, if the symbol selection section 9 moves the cursor 34 to the symbol 33 whose attribute data is not registered or whose attribute data is desired to be changed from among the symbols flicker-displayed by the symbol identification display section 8, the basic The item list 35 registered in the database 1 is displayed on the same screen of the CRT display device 6 by the item display unit 10.

Accordingly, by inputting the attribute data of the corresponding symbol of each maintenance drawing using the item attribute data input section 11, the symbol attribute database of the maintenance drawing is registered on the maintenance drawing database 12.

In this way, according to this embodiment, instead of the operator who constructs the maintenance drawing database searching for symbols from input drawings and registering attribute data as in the past, the system side It can automatically check the symbols registered in advance in the basic database and notify the operator by displaying the corresponding symbol in a manner that allows it to be distinguished from other parts, such as a flicker display, making it easier to register maintenance drawings. During work, it becomes possible to find various symbols and register attribute data without losing them.
