[0001] The present invention relates to a line list generation system, a line list generation method, and a line list generation program. [Background technology]

[0002] Known drawings used in the construction, operation, and maintenance of a plant (referred to as "plant drawings") include plant building diagrams, layout diagrams, P&IDs (Piping and Instrument Diagrams), ECWDs (Elementary Control Wiring Diagrams), IBDs (Interlock Block Diagrams), single-line diagrams, and soft logic diagrams.

[0004] However, with the above technology, it is difficult to easily create a line list from a plant drawing. For example, with the above technology, a line list can be automatically created for a P&ID drawn using a 2D CAD (Computer Aided Design) dedicated to P&IDs, but it cannot be automatically created for a P&ID drawn using a 2D CAD that is not dedicated to P&IDs. As a result, plant managers are forced to manually create line lists for P&IDs drawn using a 2D CAD that is not dedicated to P&IDs, which is inefficient.

[0005] The present invention has been made in view of the above, and has an object to easily create a line list from a plant drawing. [Means for solving the problem]

[0007] In a line list generation method according to one embodiment of the present invention, a computer executes a process of acquiring drawings used for the construction, operation, and maintenance of a plant, detecting symbols and lines included in the drawings, and generating a line list for piping to be installed in the plant based on the detection results.

[0008] A line list generation program according to one embodiment of the present invention causes a computer to execute the following process: acquire drawings used in the construction, operation, and maintenance of a plant; detect symbols and lines included in the drawings; and generate a line list for piping to be installed in the plant based on the detection results.

[0011] A line list generation system, a line list generation method, and a line list generation program according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings. Note that the present invention is not limited to the embodiments described below.

[0012] 1. Configuration and Processing of Line List Generation System 100 The configuration and processing of a line list generation system 100 according to an embodiment will be described in detail using Fig. 1. Fig. 1 is a diagram showing an example of the configuration and processing of the line list generation system 100 according to an embodiment. Below, an example of the overall configuration of the line list generation system 100, an example of the processing of the line list generation system 100, and the effects of the line list generation system 100 will be described.

[0013] (1-1. Example of the overall configuration of the line list generation system 100) An example of the overall configuration of a line list generation system 100 according to an embodiment will be described. The line list generation system 100 includes a server device 10, which is a line list generation device, and a plant manager terminal 20 used by a plant manager O. The server device 10 and the plant manager terminal 20 are connected to each other via a predetermined communication network (not shown) so as to be able to communicate with each other via wired or wireless communication. The predetermined communication network may be various communication networks such as the Internet or a dedicated line. The line list generation system 100 shown in FIG. 1 may include a plurality of server devices 10 or a plurality of plant manager terminals 20.

[0014] (1-2. Example of the overall processing of the line list generation system 100) An example of the overall processing of the line list generation system 100 according to the embodiment will be described. Note that the processing of steps S1 to S9 below may be executed in a different order. Also, some of the processing of steps S1 to S9 below may be omitted.

[0015] (1-2-1. Plant drawing information transmission processing) First, the plant manager terminal 20 transmits plant drawing information to the server device 10 (step S1). For example, the plant manager terminal 20 transmits plant drawing information selected by an operation of the plant manager O to the server device 10. At this time, the server device 10 acquires and stores the plant drawing information.

[0016] Here, plant drawings are drawings used for the construction, operation, and maintenance of a plant, such as plant building drawings, layout drawings, P&IDs, ECWDs, IBDs, single-line diagrams, soft logic diagrams, etc., created using digital data.

[0017] (1-2-2. Plant drawing display processing) Second, the plant manager terminal 20 displays a plant diagram (step S2). For example, the plant manager terminal 20 displays the plant diagram selected by the operation of the plant manager O on the monitor screen.

[0018] (1-2-3. Symbol and line selection processing) Third, the plant manager O selects a symbol and a line by operating the plant manager terminal 20 (step S3). For example, the plant manager O selects a pump symbol by clicking on the pump symbol in the plant drawing displayed on the monitor screen of the plant manager terminal 20. The plant manager O also selects a piping line by clicking on the piping line in the plant drawing displayed on the monitor screen of the plant manager terminal 20.

[0019] Here, a symbol is a symbol displayed on a plant drawing that indicates the components of a plant. Furthermore, the components of a plant are the plant equipment (e.g., control equipment, communication equipment, and measurement equipment) and plant facilities (e.g., tanks, pumps, and furnaces) that make up the plant. Furthermore, a line is a symbol displayed on a plant drawing that indicates a connection element that connects the components of the plant. Furthermore, a connection element is a pipe (e.g., a pipe through which a fluid flows) or wiring (e.g., a wiring through which electricity flows) that connects the plant equipment and plant facilities that make up the plant.

[0020] At this time, the plant manager O may select some of the symbols and lines included in the plant drawing, or may select all of the symbols and lines, by operating the plant manager terminal 20. That is, if the plant manager O wants to create a line list for piping in a specific range on the plant drawing, he selects the specific range of the plant drawing displayed on the monitor screen of the plant manager terminal 20. On the other hand, if the plant manager O wants to create a line list for piping in the entire range on the plant drawing, he selects the entire range of the plant drawing displayed on the monitor screen of the plant manager terminal 20. Furthermore, if the plant manager O wants to create a line list for piping included in multiple plant drawings, he selects specific ranges or the entire range of multiple plant drawings displayed on the monitor screen of the plant manager terminal 20.

[0021] (1-2-4. Symbol selection information and line selection information transmission processing) Fourth, the plant manager terminal 20 transmits the symbol selection information and the line selection information to the server device 10 (step S4). For example, the plant manager terminal 20 transmits to the server device 10 the identification information of the pump symbol selected by the plant manager O and its position information on the plant drawing, and transmits to the server device 10 the identification information of the piping line selected by the plant manager O and its position information on the plant drawing.

[0022] (1-2-5. Symbol pattern and line pattern registration process) Fifth, the server device 10 registers the symbol pattern and the line pattern (step S5). For example, the server device 10 acquires plant drawing information based on the symbol selection information received from the plant manager terminal 20, and identifies a symbol pattern from the digital data of the corresponding pump symbol. At this time, the server device 10 saves the identified symbol pattern as symbol pattern information. Furthermore, the server device 10 acquires plant drawing information based on the line selection information received from the plant manager terminal 20, and identifies a line pattern from the digital data of the corresponding piping line. At this time, the server device 10 saves the identified line pattern as line pattern information.

[0023] Here, the symbol pattern is identification information for identifying the shape of a symbol, such as the shape of the symbol, line type, color, etc. The line pattern is identification information for identifying the shape of a line, such as the line thickness, line type, color, etc.

[0024] (1-2-6. Symbol and line detection processing) Sixth, the server device 10 detects symbols and lines from the plant drawing (step S6). For example, the server device 10 searches the acquired plant drawing information to detect symbols that match or are similar to the identified symbol pattern. At this time, the server device 10 generates and stores symbol detection information including a symbol detection drawing, which is a plant drawing in which the detected symbols are highlighted by color. The server device 10 also generates and stores symbol detection information including a symbol detection list that lists the detected symbols.

[0025] The server device 10 also searches the acquired plant drawing information to detect lines that match or are similar to the identified line pattern. At this time, the server device 10 generates and stores line detection information including a line detection drawing, which is a plant drawing in which the detected lines are highlighted by color. The server device 10 also generates and stores line detection information including a line detection list that lists the detected lines.

[0026] (1-2-7. Line list generation process) Seventh, the server device 10 generates a line list from the detection results (step S7). For example, the server device 10 converts the acquired plant drawing information into a standard data format such as DEXPI (Data Exchange in the Process Industry), and generates and stores line generation information including a graph showing the connection relationships between the symbols and lines based on the detected symbols and lines. The server device 10 also uses the generated graph to generate and store line generation information including a line list showing the connection relationships between the plant equipment and piping installed in the plant.

[0027] The server device 10 detects symbols and lines using a detection model DM, which is a machine learning model, and if there is a detection error such as a missed detection or false detection in the symbol detection information or line detection information, it may notify the plant manager O of the detection error.

[0028] (1-2-8. Line generation information transmission process) Eighth, the server device 10 transmits the line generation information to the plant manager terminal 20 (step S8). For example, the server device 10 transmits the line generation information including a graph and a line list to the plant manager terminal 20.

[0029] (1-2-9. Line list display processing) Ninth, the plant manager terminal 20 displays a line list (step S9). For example, the plant manager terminal 20 displays on a monitor screen a line list indicating the plant equipment and piping connected upstream and downstream of the fluid flowing through each piping, along with the identification information of each piping. The plant manager terminal 20 may also display on a monitor screen a graph indicating the connection relationships, with symbols represented by nodes and lines represented by edges.

[0030] (1-3. Overall effect of the line list generation system 100) Below, the background of plant drawings, an overview of the reference technology, and problems will be explained, and then the effects of the line list generation system 100 will be explained.

[0031] (1-3-1. Background of the plant drawings) In recent years, plant-related technologies have been attracting attention. For example, the international plant engineering software market has been expanding year by year and is expected to continue expanding in the future. Plant building diagrams, layout diagrams, P&IDs, IBDs, and other plant drawings are used in the construction, operation, and maintenance of plants.

[0032] Here, we will explain the historical background of plant drawings using the example of P&ID, a type of plant drawing. First, paper P&IDs were used during the introduction and widespread use of plant drawings, followed by P&IDs created using 2D CAD with digital data, followed by intelligent P&IDs with tag information for plant equipment, and it is believed that in the future, next-generation intelligent P&IDs, which are even more efficient plant drawings, will be used. In recent years, there has been a shift in P&IDs from paper P&IDs and 2D CAD P&IDs to intelligent P&IDs.

[0033] During the construction, operation, and maintenance of a plant, it is necessary to create a list of the equipment and piping shown on the plant drawings, such as the plant building diagram, layout diagram, P&ID, IBD, etc. However, when the plant drawings are P&IDs created using 2D CAD, for example, engineers must visually detect the symbols and lines of the equipment and piping from the plant drawings, which is inefficient and prone to human error.

[0034] Therefore, there is a need for technology that can register a desired symbol pattern from among the multiple symbols and lines on plant drawings used in the construction, operation, and maintenance of a plant, detect all symbols and lines on the plant drawings that match the shape of the registered pattern, and automatically create line lists for P&IDs drawn using 2D CAD that is not specifically designed for P&IDs.

[0035] (1-3-2. Overview of reference technology) Here, we will provide an overview of the reference technologies related to plant drawings. Reference technology 1 is a technology that improves the efficiency of piping route design processing in plants. Reference technology 2 is a piping routing technology that enables efficient piping routing in plant equipment with fixed routes.

[0036] (1-3-3. Problems with the reference technology) However, with the technologies of Reference Technology 1 and Reference Technology 2, a line list can be automatically created if the plant drawing is a P&ID drawn using a 2D CAD dedicated to P&IDs, but there is a problem in that a line list cannot be automatically created for a P&ID drawn using a 2D CAD that is not dedicated to P&IDs.

[0037] (1-3-4. Overview of the line list generation system 100) The line list generation system 100 includes a server device 10, which is a line list generation device, and a plant manager terminal 20 used by a plant manager O. The server device 10 detects symbols included in a plant drawing that have a matching or similar symbol pattern based on the symbol pattern of a symbol representing a selected component. The server device 10 also detects lines included in the plant drawing that have a matching or similar line pattern based on the line pattern of a line representing a selected connection element. The server device 10 then generates graph information showing the connection relationships between the symbols and lines based on the detected symbols and lines, and generates a line list showing the connection relationships between plant equipment and piping installed in the plant. At this time, the server device 10 transmits a line list showing plant equipment and piping connected upstream and downstream, and graph information showing the connection relationships between symbols and lines at nodes and edges, and displays these on the monitor screen of the plant manager terminal 20.

[0038] (1-3-5. Effects) The line list generation system 100 efficiently detects symbols and lines from plant drawings used for the construction, operation, and maintenance of a plant, automatically creates a line list, and can provide it to users of the plant drawings, such as plant managers O, plant engineers, plant construction companies, piping designers, etc. Furthermore, the line list generation system 100 can automatically create a line list even if the plant drawing is a P&ID drawn using a 2D CAD that is not dedicated to P&ID.

[0039] As described above, the line list generation system 100 makes it possible to easily create a line list from a plant drawing, and is therefore expected to contribute to the development of plant-related technologies, the market of which is expanding.

[0040] 2. Configuration and Processing of Each Device in the Line List Generation System 100 2 to 9, configuration examples and processing examples of each device included in the line list generation system 100 shown in Fig. 1 will be described. Below, an example of the configuration of the entire line list generation system 100 according to the embodiment will be described, and then configuration examples and processing examples of the server device 10 and the plant manager terminal 20 will be described in detail.

[0056] (2-2-4-4. Line pattern information storage unit 14d) The line pattern information storage unit 14d stores line pattern information. For example, the line pattern information storage unit 14d stores a line pattern identified by a detection unit 15c of the control unit 15, which will be described later. An example of data stored in the line pattern information storage unit 14d will now be described with reference to FIG. 6.

[0059] (2-2-4-5. Line detection information storage unit 14e) The line detection information storage unit 14e stores line detection information. For example, the line detection information storage unit 14e stores line detection information generated by a detection unit 15c of the control unit 15, which will be described later. Here, an example of data stored in the line detection information storage unit 14e will be described with reference to FIG. 7.

The detection unit 15c stores the identified symbol pattern in the symbol pattern information storage unit 14b.

[0084] To explain a specific example, when the detection unit 15c receives "Pump P-1-001", which is the identification information of the selected "Pump P-1" symbol, and "Plant Drawing PD001(5,10)", which is the position information on the plant drawing, the detection unit 15c acquires the plant drawing information of "Plant Drawing PD001" from the plant drawing information storage unit 14a, identifies the digital data of the "Pump P-1-001" symbol from the identification information and position information, identifies {shape: "S-XXXX", line type: "solid line", color: "orange"} as the symbol pattern of "Pump P-1-001", and stores it in the symbol pattern information storage unit 14b, thereby registering the symbol pattern.

[0086] To explain a specific example, when the detection unit 15c receives ``Pump P-1-001'', which is the identification information of the selected ``Pump P-1'' symbol, and ``Plant Drawing PD001(5,10)'', which is the position information on the plant drawing, the detection unit 15c acquires the plant drawing information of ``Plant Drawing PD001'' from the plant drawing information storage unit 14a, identifies the digital data of the ``Pump P-1-001'' symbol from the identification information and position information, identifies the symbol angle, which is the orientation of the ``Pump P-1-001'' symbol, as {symbol angle: ``180°''}, and stores it in the storage unit 14.

[0087] (Symbol text specific processing) The detection unit 15c executes a symbol text identification process. For example, the detection unit 15c uses digital data to identify symbol text, which is text associated with the symbol whose selection has been accepted. The detection unit 15c may store the identified symbol text in the storage unit 14.

[0088] To explain a specific example, when the detection unit 15c receives "Pump P-1-001", which is the identification information of the symbol of the selected plant equipment "Pump P-1", and "Plant Drawing PD001(5,10)", which is the location information on the plant drawing, the detection unit 15c acquires the plant drawing information of "Plant Drawing PD001" from the plant drawing information memory unit 14a, identifies the digital data of the symbol of "Pump P-1-001" from the identification information and location information, identifies {Symbol Text: "S-YYYY"} as the symbol text, which is the text associated with the symbol of "Pump P-1-001", and stores it in the memory unit 14.

[0089] (Symbol detection process) The detection unit 15c executes a symbol detection process. For example, the detection unit 15c detects a symbol from a plant drawing. The detection unit 15c detects a symbol from a plurality of symbols included in the plant drawing based on the pattern of the symbol whose selection has been accepted.

[0091] Furthermore, when the detection unit 15c receives {symbol angle information: "detect a perfectly matching symbol"} as a detection condition for detecting the symbol of "Pump P-1" in the "Plant Drawing PD001", it detects symbols with a symbol angle of "180°" from among the symbols with matching symbol patterns.

[0092] Furthermore, when the detection unit 15c receives {symbol text information: "detect symbol containing text"} as a detection condition for detecting the symbol of "Pump P-1" in "Plant Drawing PD001", it further detects symbols whose symbol text is "S-YYYY" from among the symbols that match the symbol pattern.

[0093] (Symbol detection information generation process) The detection unit 15c executes a symbol detection information generation process. For example, the detection unit 15c generates symbol detection information, which is a detection result related to the detected symbol. At this time, the detection unit 15c generates the symbol detection information including identification information and position information of the detected symbol. Furthermore, the detection unit 15c generates, as the symbol detection information, a symbol detection drawing, which is a plant drawing in which the detected symbol is highlighted. Furthermore, the detection unit 15c generates a symbol detection list that lists the detected symbols.

[0101] To explain a specific example, when the detection unit 15c receives "Piping PL-1-002", which is the identification information of the selected "Piping PL-1" line, and "Plant Drawing PD001(7,8)", which is the position information in the plant drawing, the detection unit 15c acquires the plant drawing information of "Plant Drawing PD001" from the plant drawing information memory unit 14a, identifies the digital data of the "Piping PL-1-002" line from the identification information and position information, identifies {Line number: "L-YYYY"} as the line number associated with the "Piping PL-1-002" line, and stores it in the memory unit 14.

[0102] (Line detection processing) The detection unit 15c executes a line detection process. For example, the detection unit 15c detects lines from a plant drawing. At this time, the detection unit 15c detects lines from a plurality of lines included in the plant drawing based on the pattern of the line whose selection has been accepted. The detection unit 15c also detects all lines from the displayed plant drawing, including the line used for selection, whose shape matches the registered pattern. The detection unit 15c also detects all lines from a plurality of lines included in the plant drawing whose direction matches. The detection unit 15c also detects all lines from a plurality of lines included in the plant drawing whose line numbers match.

[0103] To explain a specific example, when the detection unit 15c receives {line form information: "detect lines with completely matching thickness" / "detect lines with completely matching line type" / "do not distinguish colors"} as the detection conditions for detecting the lines of "piping PL-1" in "plant drawing PD001", it acquires the plant drawing information of "plant drawing PD001" from the plant drawing information storage unit 14a, acquires the line pattern of "piping PL-1" {thickness: "L-XXXX", line type: "solid line", color: "red"} from the line pattern information storage unit 14d, searches the plant drawing information of "plant drawing PD001", and detects {"piping PL-1-001", "piping PL-1-002", "piping PL-1-003", ..., "piping PL-1-010"} as lines with a matching line pattern {thickness: "L-XXXX", line type: "solid line"}.

[0104] Furthermore, when the detection unit 15c receives {line angle information: "detect a line that matches perfectly"} as a detection condition for detecting the line of "piping PL-1" in "plant drawing PD001", it detects lines with a line angle of "180°" among the lines whose line patterns match or are similar.

[0105] In addition, when the detection unit 15c receives {line number information: "detect line including line number"} as a detection condition for detecting the line of "piping PL-1" in "plant drawing PD001", it further detects a line with the line number "L-YYYY" from among the lines with matching or similar line patterns.

[0106] (Line detection information generation process) The detection unit 15c executes a line detection information generation process. For example, the detection unit 15c generates line detection information, which is a detection result related to the detected lines. At this time, the detection unit 15c generates, as the line detection information, a line detection drawing, which is a configuration diagram in which the detected lines are highlighted. The detection unit 15c also generates a line detection list, which lists the detected lines. The detection unit 15c stores the generated line detection information in the line detection information storage unit 14e.

[0107] To explain a specific example of a line detection drawing, the detection unit 15c acquires plant drawing information for "Plant Drawing PD001" from the plant drawing information storage unit 14a, generates plant drawing information for "Plant Drawing PD001" in which the lines corresponding to the identification information of the detected "Pipe PL-1" lines {"Pipe PL-1-001", "Pipe PL-1-002", "Pipe PL-1-003", ..., "Pipe PL-1-010"} are highlighted by coloring them blue, and stores the generated plant drawing information in the line detection information storage unit 14e.

[0109] (Flow direction detection process) The detection unit 15c executes a flow direction detection process. For example, the detection unit 15c detects the flow direction of a fluid or a signal in the plant drawing by using the detected symbols, the detected lines, and directional symbols included in the plant drawing.

[0110] To explain a specific example, when the detection unit 15c detects "Pump P-1" in "Plant Drawing PD001" and detects the line of "Pipe PL-1" in "Plant Drawing PD001," the detection unit 15c identifies the connection relationship from the position information of "Pump P-1" and "Pipe PL-1" in "Plant Drawing PD001" and detects the flow direction of the fluid or signal in the identified connection relationship. At this time, if the flow direction can be identified from the identified connection relationship, the detection unit 15c detects the identified flow direction. Furthermore, if the flow direction cannot be identified from the identified connection relationship, the detection unit 15c detects the flow direction according to symbols indicating the flow direction, such as arrows and arrow feathers, written on the plant drawing.

[0111] (2-2-5-4. Generation section 15d) The generating unit 15d generates various types of information. The generating unit 15d may store the generated various types of information in the storage unit 14. The standard format conversion process, graph generation process, and line list generation process will be described below.

[0112] (Standard format conversion process) The generation unit 15d executes a standard format conversion process. For example, the generation unit 15d converts drawing data into a standard data format. At this time, the generation unit 15d converts the drawing data into DEXPI as the standard data format. Here, DEXPI is an information model for process automation standardized by OPC UA (Open Platform Communications Unified Architecture).

[0113] To explain a specific example, the generation unit 15d acquires plant drawing information of "Plant Drawing PD001" from the plant drawing information storage unit 14a and converts it into "Plant Drawing PD001-S," which is a standard data format. The generation unit 15d also acquires plant drawing information of "Plant Drawing PD002" from the plant drawing information storage unit 14a and converts it into "Plant Drawing PD002-S," which is a standard data format. The generation unit 15d also acquires plant drawing information of "Plant Drawing PD003" from the plant drawing information storage unit 14a and converts it into "Plant Drawing PD003-S," which is a standard data format.

[0114] (Graph generation process) The generation unit 15d executes a graph generation process. For example, the generation unit 15d generates a graph showing the connection relationships between symbols and lines using the converted standard data format. At this time, the generation unit 15d generates a graph showing the connection relationships between symbols and lines by representing symbols as nodes and lines as edges using the drawing data converted to the standard data format DEXPI. The generation unit 15d can also generate a graph showing the connection relationships between symbols and lines using multiple drawing data converted to the standard data format.

[0115] To explain a specific example, the generation unit 15d converts each symbol included in the standard data format "Plant Drawing PD001-S" into a circular node of a predetermined size, identifies a line for which a connection is defined for each symbol, connects each node with a straight or curved edge representing the line, generates a graph showing the connection relationship between the symbols and the lines, and stores the graph as "graph information PG001" in the line generation information storage unit 14f. Furthermore, when connection positions are defined between the standard data formats "Plant Drawing PD001-S" and "Plant Drawing PD002-S," the generation unit 15d can also generate a graph showing the connection relationship between the symbols and the lines in multiple plant drawings by connecting the connection positions of the "Plant Drawing PD001-S" and the "Plant Drawing PD002-S" with edges.

[0116] (Line list generation process) The generation unit 15d executes a line list generation process. For example, the generation unit 15d generates a line list related to piping installed in the plant based on the detection result. At this time, the generation unit 15d generates a line list indicating the connection relationship between the equipment (e.g., plant equipment, plant facilities) installed in the plant and the piping, using the detected symbols and line identification information and the generated graph. The generation unit 15d also generates a line list indicating the equipment or piping connected upstream of the fluid flowing through the piping and the equipment or piping connected downstream of the fluid flowing through the piping.

[0117] To explain a specific example, first, the generation unit 15d acquires "graph information PG001" from the line generation information storage unit 14f, and acquires identification information such as {"Pump P-1-001," "Pump P-1-002," . . ., "Pump P-1-006"}, which is a symbol of the detected "Pump P-1," together with its location information, from the symbol detection information storage unit 14c. Furthermore, the generation unit 15d acquires identification information such as {"Piping PL-1-001," "Piping PL-1-002," "Piping PL-1-003," . . ., "Piping PL-1-010"}, which is a line of the detected "Piping PL-1," together with its location information, from the line detection information storage unit 14e. Second, the generation unit 15d identifies a node in the "graph information PG001" using the identification information such as "Pump P-1" and the location information. Furthermore, the generation unit 15d identifies edges of the "graph information PG001" by using the identification information and identification information of "piping PL-1" etc. Third, the generation unit 15d identifies the plant equipment and piping connected to each of the identification information of the lines of "piping PL-1" such as {"piping PL-1-001", "piping PL-1-002", "piping PL-1-003", . . . , "piping PL-1-010"}, generates a line list indicating the connection relationships between the equipment and piping installed in the plant, and stores the line list in the line generation information storage unit 14f.

[0118] At this time, if the flow direction of the fluid flowing through the piping is detected by the detection unit 15c, the generation unit 15d generates a line list including the equipment and piping connected upstream or downstream of each piping {line: "piping PL-1-001", upstream: "tank T-1-001", downstream: "pump P-1-002"}, {line: "piping PL-1-002", upstream: "pump P-1-001", downstream: "tank T-1-002"}, {line: "piping PL-1-003", upstream: "piping PL-1-001", downstream: "pump P-1-001"}, etc., and stores it in the line generation information storage unit 14f.

[0119] Furthermore, when the detection unit 15c detects text such as a line number attached to a line, the generation unit 15d generates a line list including a line comment, such as {line: "Piping PL-1-001", line comment: "XXXXXXXX"}, {line: "Piping PL-1-002", line comment: "YYYYYYY"}, {line: "Piping PL-1-003", line comment: "ZZZZZZZZZ"}, and stores it in the line generation information storage unit 14f.

In other words, the specific form of distribution or integration of each device is not limited to that shown. In other words, all or part of them can be functionally or physically distributed or integrated in any unit depending on various loads, usage conditions, etc.

[0183] Furthermore, all or any part of the processing functions performed by each device may be realized by a CPU and a program analyzed and executed by the CPU, or may be realized as hardware using wired logic.

[0184] [6. Hardware] An example of the hardware configuration of the server device 10 will be described with reference to Fig. 15. Fig. 15 is a diagram showing an example of the hardware configuration according to an embodiment. As shown in Fig. 15, the server device 10 includes a communication device 10a, an HDD (Hard Disk Drive) 10b, a memory 10c, and a processor 10d. The components shown in Fig. 15 are connected to each other via a bus or the like.

[0185] The communication device 10a is a network interface card or the like, and communicates with other server devices. The HDD 10b stores programs for operating the functions shown in FIG.

[0186] The processor 10d reads out from the HDD 10b or the like a program that executes the same processes as the respective processing units shown in FIG. 2 and loads it into the memory 10c, thereby operating a process that executes each function described in FIG. 2 or the like. For example, this process executes the same functions as the respective processing units of the server device 10. Specifically, the processor 10d reads out from the HDD 10b or the like a program that has the same functions as the acquisition unit 15a, the reception unit 15b, the detection unit 15c, the generation unit 15d, the provision unit 15e, the notification unit 15f, and the like. Then, the processor 10d executes a process that executes the same processes as the acquisition unit 15a, the reception unit 15b, the detection unit 15c, the generation unit 15d, the provision unit 15e, the notification unit 15f, and the like.

[0187] In this way, the server device 10 operates as a device that executes various processing methods by reading and executing the programs. The server device 10 can also realize the same functions as those of the above-described embodiment by reading the programs from a recording medium using a media reader and executing the read programs. Note that the programs are not limited to being executed by the server device 10. For example, the present invention can be similarly applied to cases where another computer or server device executes the programs, or where these cooperate to execute the programs.

[0188] This program can be distributed via a network such as the Internet. In addition, this program can be recorded on a computer-readable recording medium such as a hard disk, a flexible disk (FD), a CD-ROM, a magneto-optical disk (MO), or a digital versatile disk (DVD), and can be executed by being read from the recording medium by a computer.
