The database 180 includes a drawing DB 181 for storing a drawing pattern in which an object including a common shape or a part is drawn in a cable wiring diagram for various types of field instruments and device types included in facility information, design information, and control system information, And a data DB 182 in which facility information or site data is set and stored in a relational DB.

The drawing DB 181 is a loop wiring diagram of various field instruments and devices in a power plant (for example, gauge devices capable of displaying temperature and pressure, control valves, motor valves, and other power plant field instruments and devices) Drawing). Here, the drawing pattern means a drawing including a shape or object (parts and connectors) usable in common in the drawings classified into the same type.

The data DB 182 stores data for each field instrument and device type represented in the loop wiring diagram. Here, the data DB 182 includes unique identification information for each item included in the facility information, the design information, the control system information, and the field data, and a relational DB according to each unique identification information is set.

The setting unit 120 extracts a drawing pattern including a common shape or an object according to each field instrument and device type stored in the drawing DB 181 and gives unique identification information to each extracted drawing pattern.

The unique identification information is used to indicate the field instruments and devices included in the drawing, the columns and rows of the table of data stored in the data DB 182 (field instrument and device names, unique numbers of connectors and cables, Cable diameter, and specification information, an identification key).

In addition, the setting unit 120 sets unique identification information for each drawing pattern and data, and the unique identification information is stored in the drawing DB 181 and the data DB 182, or is stored as a separate DB, and is set as a relational DB.

Such unique identification information allows the loop and earing diagrams containing the data to be tracked once the data is modified.

The relational data generation unit 130 checks the unique information set for each item included in the facility information, the design information, the control system information, and the measurement data of the field instrument and the instrument stored in the data DB 182 and inputs and / Or the data elements corresponding to the set conditions are recombined to generate new data.

That is, the relational data generation unit 130 generates a relational data condition (for example, a column of a table and a row, unique identification information for each item and / or a name) included in the command input through the input unit 160, To generate relational data.

Also, when the identification information of the modified data is received under the control of the control unit, the relational data generation unit 130 tracks the relational data including the modified data and updates the relational data as the modified data.

The drawing unit 140 has an editing function including a drawing pattern displayed on the display 170 as at least one of a figure, a line and a symbol, and copying, deleting, modifying, etc. of the drawing pattern output. Preferably, the plotting unit 140 may correspond to any one of a 2D and / or 3D design program.

The mapping unit 150 maps the relational data generated by the relational data generation unit 130 to the drawing pattern represented by the display unit 170 by the construction unit 140. That is, the mapping unit 150 maps data to the drawing pattern implemented by the drawing unit 140 and outputs the mapped data to the display 170.

The input unit 160 outputs a user's command by a combination of keys set as an input device such as a keyboard and / or a mouse.

The display 170 outputs the retrieved drawing and the mapped data. More preferably, the display 170 may simultaneously output the stored and / or retrieved information and the plotting screen in the database 180.

The marking unit 190 displays the modified data under the control of the control unit 110 as modified data by at least one of the color, symbol, and format set in the drawing of the loop wiring diagram.

The control unit 110 stores the unique identification information given to the item matched with the command in accordance with the search command (for example, field instrument and device name, cable connector name, cable diameter, connector terminal number) input from the input unit 160 And outputs the retrieved drawing pattern to the display 170. [0064]

The control unit 110 controls the construction unit 140 to connect cables connected to the field instruments and the control system from the equipment and controls the relational data generation unit 130 to generate relational data corresponding to the output design pattern . In addition, the control unit 110 controls the mapping unit 150 to map the relational data to the drawing pattern.

The control unit 110 controls the drawing unit 140 to control the drawing unit 140 to copy the selected drawing to the selected location through the display unit 170 And controls to output it.

If some of the data stored in the data DB 182 is modified, the control unit 110 controls the relational data generation unit 130 to update the relational DB including the corresponding data by tracking the modified data, The control unit 150 controls the marking unit 190 to display the modified data in the corresponding part.

That is, the present invention extracts patterns that are patterned for each type of field instrument and device, automatically generates and maps data that is reconstructed by a relational DB to a pattern of drawings set according to input field instruments and device types, Ring diagrams can be created automatically.

In addition, even when the same configuration is repeatedly required due to the characteristics of the loop wiring diagram, the present invention can generate only a single connection configuration and then copy and generate a desired number of the connection configuration, As time and manpower, more precise drawings can be completed.

Further, according to the present invention, when the data is modified, the drawing can be automatically modified, thereby shortening the time and manpower required for a separate drawing modification operation.

The present invention implements a method of automatically generating a loop wiring diagram of a power plant using a relational DB through the above-described configuration, which will be described with reference to the flowcharts below.

3 is a flowchart illustrating a method of automatically generating a loop wiring diagram of a power plant using a relational DB according to the present invention.

Referring to FIG. 3, there are shown a setting step (S10) of classifying the accumulated drawings and data according to the types of field instruments and devices and setting the relational DB by giving unique identification information, (S30) for searching and outputting a pattern of a drawing corresponding to a new job command, a wiring step (S40) for wiring the output drawing pattern, a drawing step A data mapping step S60 for mapping the relational data to a drawing, a step S70 for copying and storing the completed drawing, a modification of data (S80) for judging whether or not the modified data is stored in the memory (S80), and a storing step (S90) for updating and storing the modified data by tracking the data.

The setting step S10 extracts and stores the patterned pattern for each field instrument and device type in the drawing included in the facility information or control system information accumulated in the database 180 for a predetermined period of time, And setting the unique identification information.

The setting unit 120 stores unique identification information for each item of the pattern diagram and data stored in the drawing DB 181 and the data DB 182 under the control of the controller 110. [ Herein, the unique identification information of the drawings and the data is set so that the figure and the data including the same item such as the part specification, for example, the connector name, the number of the connector terminals, and the cable diameter, can be interlinked.

The new job information confirmation step S20 is a step of the controller 110 receiving the new job command from the input unit 160 and confirming the field instrument and the device type or part information included in the input new job command. The control unit 110 confirms the type of the field instrument and the device included in the new work instruction output from the input unit 160. [ For example, an operator may input information about the target field instrument and device type (field instrument and device name or set identification code, cable connector name or specification information, connector terminal number, and cable specification information) for generating a loop wiring diagram .

The drawing search and output step S30 is a step for the controller 110 to search for and output a drawing pattern corresponding to the type of the field instrument and the device input in the new job information confirmation step. The control unit 110 confirms the command input through the input unit 160 and outputs a list of drawing patterns according to the type of the apparatus and the type of instrument corresponding to the command.

Then, the operator operates the input unit 160 (e.g., a mouse) to select his or her desired drawing pattern from the list output through the display 170. Accordingly, the input unit 160 outputs a drawing pattern selection command to the control unit 110. The control unit 110 outputs the selected drawing pattern to the display 170. At this time, the outputted drawing pattern is selected and outputted according to facility information, control system information and design information. This will be described with reference to FIG.

4 is a diagram showing an example of a pattern pattern and a cable connection in a method of automatically generating a loop wiring diagram of a power plant using a relational DB according to the present invention.

Referring to FIG. 4, the controller 110 outputs the drawing patterns 210 to 230 retrieved in the drawing search and output step S30, respectively. The control unit 110 searches the drawing pattern 210 of the facility information and the drawing pattern 230 of the design information by searching the drawing patterns 210 to 230 according to the corresponding field instruments and the device type stored in the drawing DB 181, And outputs the drawing pattern 220 of the system, respectively.

At this time, the drawing patterns 210 to 230 may be outputted in one line by combining the drawing patterns of the facility information or the control system, or two or more drawing patterns of the same pattern may be collectively outputted.

Alternatively, the drawing pattern may be increased as much as the operator desired by copying and pasting the drawing patterns 210 to 230 after output of one row.

In the wiring step S40, the control unit 110 controls the drawing unit 140 to connect between the drawing pattern 210 of the facility information, the drawing pattern 220 of the control system, and the drawing pattern 230 of the design information . The control unit 110 includes objects 211 and 212 corresponding to the facility information outputted in the drawing search and output step S30, an object 231 corresponding to the design information, an object 221 corresponding to the control system information And controls the plotting unit 140 to plot the cable connection. Accordingly, the construction unit 140 constructs a cable so as to connect between the connector terminals included in each drawing pattern under the control of the control unit 110.

In the relational data generation step S50, the control unit 110 controls the relational data generation unit 130 to generate data of the facility information set in the relational DB, data of the design information, data of the control system information, The relational data including the unique identification information that matches the drawing pattern is generated from the measurement data. This is shown in Fig. 5 (a).

For example, the relational data generation unit 130 constructs a relational DB between the data of the facility information and the data of the design information, and re-assembles each data to generate relational data. In this way, the correlated data can be listed in the table as shown in the table (a) of FIG. 5 and output to the display 170.

In addition, the relational data generation unit 130 extracts relational data according to the relational data condition input through the input unit 160. Here, the relational data condition may be set to column, row, and unique identification information assigned for each item of each data table.

5 (a) shows an example of a relational DB between facility information and design information, and data of design information and control system information and / or data of facility information or control system are expressed in relational DB It is also possible to newly generate data.

That is, the present invention generates data to be applied to a drawing pattern by setting accumulated facility information or control system information and measurement data of a field instrument and a device in a relational DB.

The data mapping step S60 is a step in which the control unit 110 controls the mapping unit 150 to map relational data to a drawing pattern and express it in a drawing. The controller 110 controls the relational data generated by the relational data generator 130 to map each object of the drawing pattern to represent data of each object included in the drawing pattern. An example of such a data mapping is as shown in Fig. 5 (b).

5B, the mapping unit 150 includes connector terminals included in the first object 211 and the second object 212 among the drawing patterns of the facility information and the design information, The connected cable information is mapped to the set position of the drawing pattern.

In addition, the present invention can generate the same relational data with the same number as the number of the drawing pattern.

For example, if a drawing pattern of a total of 16 rows is shown in the drawing pattern, relational data also generates relational data of 16 rows. At this time, the drawing pattern and data of each row include the same shape and data as the other rows.

Thus, the operator selects data displayed in the first row (No. 1), for example, in the list items of the relational data outputted to the display 170 using the mouse or the keyboard, Drag. Then, the control unit 110 maps the selected data to the selected drawing pattern. The above procedure describes the process of mapping the data after the operator selects the relational data and the outputted drawing pattern, respectively.

Alternatively, the present invention can automatically map the drawing pattern and the relational data outputted on the drawing by the control of the control unit 110 after the relational data is generated, not the mapping between the data and the drawing pattern by the selection of the operator as described above Do.

The copying and storing step S70 is a step in which the control unit 110 copies and copies the drawing pattern in which the data is mapped according to the copy command and / or the save command, by a preset number and / or number.

For example, when the copying command is outputted together with the selection of the area from the input unit 160, the control unit 110 controls the construction unit 140 to copy the selected area to a designated position, You can create a diagram.

When an edit command is inputted through the input unit 160, the control unit 110 controls the construction unit 140 to control the drawing in accordance with the inputted command.

That is, the construction unit 140 is preferably capable of implementing the functions used in a design program (for example, a 2D and / or a design program) capable of deforming the shape, plotting, and inputting data in the output drawing pattern.

The modification determination step S80 is a step in which the control unit 110 determines whether or not the data stored in the data DB is modified. Here, the operator uses the input unit 160 (e.g., a mouse or a keyboard) to search for data represented in the completed loop wiring diagram in the copying and storing step S70. Accordingly, the controller 110 retrieves data requested to be searched by the input unit 160 from the data DB and outputs the retrieved data to the display. Then, the controller 110 determines whether the data is corrected by checking the input command.

The storing step S90 is a step in which the controller 110 changes and stores the loop wiring diagram using the modified data if the modified data exists in the modification determining step S80. Here, the control unit 110 controls the relational data generation unit 130 to track the modified data when a post-correction storage command is input. The relational data generation unit 130 confirms the unique identification information given to the modified data, modifies the relational DB including the corresponding data, and searches for the loop wiring diagram in which the corresponding data is expressed.

The control unit 110 controls the mapping unit 150 to reflect the modified data on the retrieved loop wiring diagram and controls the marking unit 190 to display the modified data in the information data DB 182, And displays the correction on the drawing as any one of the set character, symbol, or pattern.

That is, according to the present invention, when the data is modified, the loop wiring diagram automatically linked thereto can also be automatically modified.
