Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to plant equipment
The present invention relates to a drawing management system for managing a large number of drawings such as device-related.

[0002]

2. Description of the Related Art In a plant such as a power plant, there are a large number of drawings regarding the installed equipment, the number of which is thousands or more is very large, and it takes a long time to obtain the necessary drawings. There is. Therefore, there is a need for a method of automatically searching for desired drawings faster. A full-text search method and a keyword search method are known as computer-based search systems. The ideal search method requires system development equivalent to full-text search of drawings.

Conventionally, the following retrieval methods are known as methods for retrieving drawings using a computer.

In the first search method, the title name is written on each drawing and registered in the computer, and the title name estimated to be input by the registrant when the person in charge other than the registrant searches is input into the computer. Then, the desired drawing is output. However, since this search method is registration of only drawing titles, a desired drawing cannot be searched unless the searcher inputs the title name entered by the drawing creator into the computer. Further, since the device name is not registered, the relationship between the device name and the drawing is unknown. Therefore, this search method is not a practical search method because drawings relating to various types of devices are searched and output.

Further, in this search method, it is necessary to input a title name in advance in order to search for a drawing, which often causes an input error in the title name, and it may not be possible to search for a desired drawing. In particular, plant drawings include drawings that have been exported to many countries, not only domestically, and the method of searching by title is not practical for global drawing management such as plant drawings of exported equipment. That is, in order to process these drawings, it is necessary for an advanced engineer to classify and process the drawings over a long period of time.

The second search method is a search method based on a hierarchical structure, in which each drawing is registered in a computer in association with a predetermined hierarchical structure, and when searching, the location where the target drawing is registered. Is determined from the above hierarchical structure, the corresponding keyword is input to the computer, and the corresponding drawing is searched.

However, since this search method does not have a hierarchical structure for each facility / apparatus, a narrowed search cannot be performed when searching for a drawing for a specific apparatus. Further, even if a computer search system having a hierarchical structure for devices is constructed, the category of the device needs to be known to all users in advance. It is necessary to create a dictionary as a means for making all users aware of the device category in advance, and make this dictionary known to all searchers before the survey. Retrieving the device name from the dictionary takes a considerable amount of time and is not an efficient method. Furthermore, this search method also has a problem that a desired drawing cannot be searched for when a keyword for searching a device category or a hierarchical structure is input in many cases.

The third search method is the creation date of each drawing,
When registering in the computer the attributes depending on the drawing type, such as creation department, outline drawing, and system diagram, in association with the drawing, and when searching, enter the keyword that anticipates the attribute that the target drawing corresponds to This is a method for searching for drawings. However, there are many devices in the plant, and there is a problem that only users who are familiar with all these device names can use them. Furthermore, this search method also has a problem that a desired drawing cannot be searched for when a keyword for searching a device category or a hierarchical structure is input in many cases.

The plant drawings are used for maintenance, breakdowns,
It is required at the time of the next construction, new design, research and development, etc. Therefore, a method for searching the plant drawing is required so that anyone can search for the corresponding drawing. If the corresponding drawing cannot be retrieved, for example, if it fails, the repair time will be long, and if the plant is a power plant, many customers will be annoyed. Further, at the time of new design, there is a problem that the design period becomes long because the development time is required again and the cost increases.

[0010]

As described above, the conventionally proposed drawing retrieval method is a method for retrieving a desired drawing by inputting a retrieval keyword or a retrieval character. , It was a method to search the best drawing or not. There was a demand for the development of a search method that would allow the search for the most suitable drawing regardless of who searched domestically or foreignly.

The present invention has been made to solve such a conventional problem, and it is possible to retrieve a desired drawing by selecting a device name and a drawing type name without inputting characters or numbers. It is intended to provide a drawing management system. Another object of the present invention is to provide a drawing management system in which the number of searches is minimized to reduce the occurrence of search errors.

[0012]

In order to achieve the above object, a drawing management system having the following configuration is provided. That is, the drawing management system according to claim 1 searches the drawings of a plurality of devices constituting a plant by displaying the search button on the search screen in which the search button is displayed in association with each search selection pixel. In the drawing search system for selecting the drawing by selecting, a search screen display means for displaying the device name column of the device and the type name column of the drawing on the vertical axis and the horizontal axis as the search screen, Drawing group search means for selecting a desired device name and drawing type name from the device name column and drawing type name column to search for a corresponding drawing group, and one or more searched drawing groups And a drawing display means for displaying the drawings side by side.

According to the first aspect of the present invention, the search is performed on the search screen displaying the device name string and the type name string of the drawing. Therefore, a desired drawing can be searched from a drawing of tens of thousands of pages by one search operation. it can. Further, since the device name and the drawing type name are listed in the search screen, there is no occurrence of a search error due to typographical error. Furthermore, since the input of the search key is an operation of simply selecting a desired keyword from the display screen of the device name column and the type name column of the drawing, anyone can make a desired request in the same manner as long as they have a search task. You can search for drawings.

That is, since the input of the search key is an input method for selecting the desired device name and drawing type name in the search screen, the selection target for the search is always displayed on the screen, so that each user Can search for the optimum drawing, and can search for the same drawing no matter who searches. Furthermore, it is effective for global drawing management such as plant drawings of exported equipment.

The drawing management system of claim 2 is the same as that of claim 1.
In the drawing management system described above, the search screen display means displays the search screen in a grid form by dividing the device name column and the type name of the drawing into vertical and horizontal axes, and displays the device name and the drawing. When the type name is selected, the number of retrieved drawings is displayed at the intersection of the grid display.

According to the invention of claim 2, since the search result is displayed on the search screen, the relationship between the search expression and the search result,
The searcher can clearly recognize the end of the search.

The drawing management system of claim 3 is the same as that of claim 1.
In the drawing management system described above, the device name column and the type name column of the drawing displayed on the search screen indicate the desired device name and drawing type name by moving the scroll screen on the search screen. It is characterized in that it can be moved to a desired display position and selected.

According to the third aspect of the present invention, even if the device name sequence and the type name sequence of the drawing become large in number, they are moved and displayed by the scroll bar on the search screen. It is possible to display a desired number of device names and type names of the drawings that are necessary for searching for the item in a faster manner. By increasing the device name column and the type name of the drawing, the desired drawing can be accurately searched more quickly.

The drawing management system of claim 4 is the same as that of claim 1.
In the described drawing management system, the drawing displayed on the screen among the searched drawing groups can be changed, and the changed drawing can be newly stored as an improved drawing. .

According to the invention of claim 4, since a plurality of retrieved drawings can be displayed on the same drawing, the optimum drawings can be efficiently narrowed down.

In order to be able to retrieve a valid optimum drawing, it is important that the relationship between the drawing registered in the database and the actual device is clear. In a plant drawing, a large number of drawings exist for each large number of devices, and it is important that necessary drawings are also distinguished and searched for by device.

[0022]

As shown in FIG. 5, a device name-based database 4 in which a search dictionary in which a device code and a serial number of the corresponding drawing are stored in association with each device installed in the plant is stored. The drawing data file 5 stored with the above drawing numbers associated with each drawing created at the time of construction, improvement, and remodeling, operation for inputting drawing data, operation for displaying a search screen, drawing An input means 6 for inputting each operation information such as an operation for searching and an operation for displaying a search result, and a search screen data storing a search screen as shown in FIG. Base 2, the drawing type database 3, the device name by the database 4, stored in the drawing database 5, the stored data of the read operation control to CPU
7, a search screen database 2, a drawing type database 3, a device name-specific database 4, a RAM 8 in which a control program of the CPU 6 for searching the drawings stored in the drawing database 5 is stored, a search screen, searched drawings, etc. The display means 9 for displaying, the user terminal 10, etc. are comprised.

The search screen database 2 stores a grid search screen 21 as shown in FIG. 2 for each plant. In this grid-shaped search screen 21, the equipment names of the equipments constituting the plant are displayed in a row on the horizontal axis, and the equipment name row 22 is displayed, and the type names of the drawings are displayed in a row on the vertical axis. This is a screen on which the type name column 23 is displayed. This search screen 21 is created for each plant and the search screen database 2
Are stored and registered in. As shown in FIGS. 3 and 4, arithmetic processing characters (codes) assigned as attributes are preset in the equipment name of each facility and the type name of the drawing.
3 shows the type code of the drawing, and FIG. 4 shows the device code. The search screen 21 is used to search for drawings.
This is the screen first displayed on the display means 7.

Further, the drawing type name database 3 includes the drawing type names as shown in FIG. 3, the drawing type code assigned as an attribute in association with each drawing type name, and all drawings to be managed for each drawing type. It is a table that is classified and registered.

The device name-specific database 4 is a table in which device names as shown in FIG. 4, device codes assigned as attributes in association with each device name, and all managed drawings are classified and registered for each device. Is.

In the drawing data file 5, for all managed drawings, arithmetic processing characters (code, drawing number, etc.) assigned as attributes to each drawing are associated and stored and registered as shown in FIG. Further, the name of the drawing is also stored and registered as needed.

The search screen 21 is an image displayed on the display surface 24 of a display device such as a CRT monitor or a liquid crystal screen. On the vertical axis is a column 23 of drawing type names, such as outline drawings, assembly drawings,
A basic diagram, a piping diagram, a perspective view, a component diagram, an electric circuit diagram, a system diagram, a system diagram, a sectional view, a logic diagram, etc. are displayed as selected pixels. The horizontal axis is a column 22 of equipment names such as equipment and devices that configure the plant. For example, a generator that configures a power plant, a turbine, a condenser, a condensate demineralizer, a low pressure feed water heater, a high pressure feed water heater, and a boiler. Such devices are displayed in rows as selected pixels.

Since the type name column 23 and the device name column 22 of the drawing displayed on the vertical axis and the horizontal axis are a large number of columns, scroll bars 25 and 26 are provided respectively, and display objects can be displayed vertically and horizontally. It is configured so that the type names and device names of many drawings can be moved to be displayed and selected. The ability to display the type names and device names of a large number of drawings makes it possible to search for more accurate drawings. Therefore, a drawing when a new problem is later proposed and developed has a structure having expandability so that the type name and the device name of the drawing can be sequentially added and stored.

At the intersection 27b2 between the type name of the drawing, for example, the assembly drawing and the device name, for example, the B device, the search result is displayed, for example, by the number of the search output drawings. The search ends when the intersection 27 is changed to a numerical display. When the cursor is moved to the drawing number part (selected pixel) of this search result and the mouse is clicked to select, the search screen 2
1 changes to a drawing display screen 28 on which the searched drawing is displayed. The intersection 27 is shown in FIG. 2 as a coordinate.

The drawing display screen 28 can be displayed as desired. For example, the drawing display screen 28 can display a screen (title list) of drawing numbers and drawing names of the retrieved drawings as shown in FIG. In the title list, selecting a desired title list display portion (selected pixel) means displaying one desired drawing on the search screen 21. If a display device of a personal computer is used as this display device, the search screen can be printed (copied), and by connecting this system to the Internet, it can be sent to a remote person by electronic mail. . The system can be connected to the Internet by connecting the system via a server. A remote computer connected to the Internet can be searched using the drawing management system 1.

For example, when a plant breaks down, a drawing of the broken point and a repair method can be obtained at hand by a personal computer connected to the Internet. If you want to browse past drawings during business negotiations, you can obtain the desired drawings at the same seat.

Further, as a method of displaying the retrieval result, a plurality of drawings can be displayed as shown in FIG. The number of drawings that can be displayed at one time varies depending on the size of one display screen, but the screens are sequentially moved by operating the scroll bars 25 and 26, and all search reply drawings are displayed on the drawing display screen 28. It can be displayed in (selected pixel). As a result of browsing the search response drawings, the display of one desired drawing is to move the cursor to the drawing that is made into a small image on the drawing display screen 28 and click. As a result, the drawing display screen 28 is changed to one enlarged drawing. Figure 6
Shows a state in which 12 drawings are displayed on the drawing display screen 28. Since these eight drawings have the same equipment and the same type of drawings, they are large enough to select the desired drawing when, for example, 12 drawings of the outline drawing of the generator are displayed. , The number of sheets. On the drawing display screen 28, the total number of retrieved drawings is displayed in the upper part, and the remaining number of drawings not displayed in the searched drawings is displayed in the lower part.

Next, the registration of drawings will be described with reference to the flowchart of FIG. The same parts as those in FIGS. 1 to 6 will be described using the same reference numerals, and detailed description thereof will be omitted.

First, a key is operated from the input section 6 to operate a start button (S1). A device code as an attribute of a unit component and a drawing type code table for all drawings are created and registered as a search dictionary (S2).

The registration of the drawing is performed by the key operation of the input unit 6
Read the drawing registration program stored in AM9 (S
3) Based on a predetermined code table and drawing numbering procedure manual, the device code and drawing number of the drawing to be input are input from the input unit 6 (S4). Then, the type name code and the drawing number of the drawing to be input are input from the input unit 6 (S5). The drawing information obtained by reading the drawing with the scanner is stored and registered in the drawing type name database 3, the device name database 4, and the drawing database 5 in association with the device code of the drawing, the drawing type code, and the drawing number ( S6). If the device name and drawing type name are new,
The names are additionally registered on the vertical and horizontal axes of the search screen 21 (S7). By repeating such a procedure, many drawings are registered and the drawing registration operation is completed (S).
8).

The procedure for searching the registered drawings will be described with reference to the flowchart of FIG. The same parts as those in FIGS. 1 to 7 will be described using the same reference numerals, and detailed description thereof will be omitted.

First, in order to search for a drawing, a key is operated from the input unit 6 and a start button is operated (S11).
The search screen 21 is read from the search screen database 2 and displayed on the display unit 9 (S12).

The device name is determined (S13). To select a device name, move the device name row to the left or right with the scroll bar 25, move the cursor from the input unit 6 to the display unit of the desired device name with the mouse, and click the mouse to complete the input of the device name. To do. That is, the device name is selected by reading the search dictionary shown in FIG. 4 from the device name-specific database 4 under the control of the CPU 7, and for example, when the device B is selected, the device code B001 is output, and the drawing number string stored in B001 is displayed. read out. The read drawing number string is temporarily stored in the RAM 8 under the control of the CPU 7 (S14).

The type of drawing is determined (S15). To select a drawing type, a scroll bar 26 is used to move the drawing type name column up and down, the input unit 6 is used to move the cursor to the desired drawing type display unit, and the mouse is clicked. The input of the type name of is completed.

To select the drawing type, use the search dictionary shown in FIG.
Under the control of U7, it is read from the drawing type-specific database 3, for example, if an assembly drawing is selected, the corresponding drawing type code 0Y001 is output, and the drawing number string stored in 0Y001 is read. The read drawing number string is temporarily stored in the RAM 8 under the control of the CPU 7 (S16).

After the device selection and the drawing type selection are completed,
The drawing is searched (S17). To retrieve a drawing, the CPU 7 controls the AND operation of the drawing number read by selecting the device and the drawing number read by selecting the type of the drawing. The result of this AND operation is the number sequence of the retrieved drawing. The number string in this drawing is temporarily stored in the RAM 8.

The output format is determined (S18). The determination of the output format is displayed on the display unit 9 according to the designation from the input unit 6. For example, if it is desired to display the number list as shown in FIG. 5, the number sequence of the retrieved drawing is displayed on the display screen. When the cursor is moved and clicked on the display surface of the desired drawing number within the displayed drawing numbers, the drawing of the relevant drawing number is selected and displayed on the display screen 24. That is, the CPU 7 recognizes the selection of the desired drawing number in the displayed screen, reads the corresponding drawing from the drawing data file 5, and displays it on the display unit 9.

Further, when the drawing display of the retrieval result as shown in FIG. 6 is designated, the CPU 7 reads the display program from the RAM 8 and the drawing of the number sequence of the retrieved drawings stored in the RAM 8 is controlled by this program. It is read from the drawing data file 5 and stored in the temporary RAM 8. As for the stored drawings of the retrieved drawing number string, the number of drawings that can be displayed at one time, for example, eight drawings is displayed on the display unit 9. The drawing displayed on the display unit 9 can be printed by a printer. The display of the remaining drawings after browsing is displayed on the display unit 9 by reading the remaining drawings from the RAM 6 under the control of the CPU 8 by selecting the enter key. As another display method of the drawings remaining after browsing, the drawings may be sequentially moved by the scroll bar 26 to be displayed.

In this way, the search result is displayed on the display unit 9. The retrieved drawing can be controlled to be transferred to another terminal 10 via an intranet or the Internet, or a part of the drawing can be modified and the modified drawing can be newly registered as a new drawing. In this way, the search ends (S19).

In this embodiment, the device name is selected first, but the same effect can be obtained by executing the drawing type name first. Furthermore, in the above-described embodiment, the embodiment of AND operation of the device name and the type name of the drawing has been described as the means for retrieving the drawing. However, the OR operation of the device name and the type name of the drawing also calculates the device name and the type name of the drawing. Input unit 6 for NOT calculation
It can be executed by specifying from.

In the drawing search according to this embodiment, a desired drawing can be searched by selecting a device name and a drawing type name on one search screen. This drawing search has no mistake in input key operation, no matter who operates it, no education for searching is required, and drawings with the same search result can be searched.
