1. Configuration and Process Related to Information Providing System 100-1

A configuration and a process related to the information providing system 100-1 according to the first embodiment will be described with reference to FIG. 1. FIG. 1 is a diagram illustrating the configuration example and the process example of the information providing system 100-1 according to the first embodiment. In a description below, the configuration example of the entire information providing system 100-1, the process example of the information providing system 100-1, and the effects of the information providing system 100-1 will be described.

1-1. Configuration Example of Entire Information Providing System 100-1

A configuration example of the entire information providing system 100-1 according to the first embodiment will be described. The information providing system 100-1 includes a server device 10-1 that is an information providing device (plant drawing symbol detection device), and a plant administrator terminal 20 that is used by a plant administrator O. Here, the server device 10-1 and the plant administrator terminal 20 are connected via a predetermined communication network (network) (not illustrated) so as to be able to communicate each other in a wired or wireless manner. Furthermore, for the predetermined communication network, it is possible to use various communication networks including the Internet, a dedicated line, or the like. Moreover, in the information providing system 100-1 illustrated in FIG. 1, two or more of the server devices 10-1 or two or more of the plant administrator terminals 20 may be included.

1-2. Process Example of Entire Information Providing System 100-1

A process example of the entire information providing system 100-1 according to the first embodiment will be described. Furthermore, the processes performed at Steps S1 to S7 may also be in different order. Moreover, from among the processes performed at Steps S1 to S7 described below, there may be a process that is omitted.

1-2-1. Plant Drawing Information Transmission Process

At a first step, the plant administrator terminal 20 transmits plant drawing information to the server device 10-1 (Step S1). For example, the plant administrator terminal 20 transmits the plant drawing information that has been selected by an operation performed by the plant administrator O to the server device 10-1. At this time, the server device 10-1 receives the plant drawing information and stores the received plant drawing information.

Here, the plant drawing indicates a drawing that is used for construction, operation, and maintenance of a plant, and is, for example, a building diagram, a layout drawing, a P&ID, an ECWD, an IBD, a single line connection diagram, a soft logic diagram, or the like of the plant generated by digital data.

1-2-2. Plant Drawing Displaying Process

At a second step, the plant administrator terminal 20 displays the plant drawing (Step S2). For example, the plant administrator terminal 20 displays the plant drawing that has been selected by the operation performed by the plant administrator O on a monitor screen.

1-2-3. Symbol Selection Process

At a third step, the plant administrator O selects a symbol by operating the plant administrator terminal 20 (Step S3). For example, the plant administrator O selects the symbol associated with a control instrument by performing a click operation on the symbol associated with the control instrument included in the plant drawing that is displayed on a monitor screen of the plant administrator terminal 20.

Here, the symbol indicates a sign that indicates a component of the plant and that is illustrated in the plant drawing. Furthermore, the component of the plant mentioned here indicates a plant instrument (e.g.: a control instrument, a communication instrument, or a measurement instrument) that constitutes the plant, a plant facility (e.g.: a tank or a furnace), or the like.

1-2-4. Symbol Selection Information Transmission Process

At a fourth step, the plant administrator terminal 20 transmits symbol selection information to the server device 10-1 (Step S4). For example, the plant administrator terminal 20 transmits identification information on the symbol associated with the control instrument selected by the plant administrator O or positional information on the position of the symbol illustrated in the plant drawing to the server device 10-1.

1-2-5. Symbol Pattern Registration Process

At a fifth step, the server device 10-1 registers a symbol pattern (Step S5). For example, the server device 10-1 acquires the plant drawing information on the basis of the symbol selection information received from the plant administrator terminal 20, and specifies the symbol pattern from the digital data on the symbol associated with the corresponding control instrument. At this time, the server device 10-1 stores the specified symbol pattern as symbol pattern information.

Here, the symbol pattern indicates the identification information for identifying the shape of a symbol, and is, for example, a diagram, a line type, a color, or the like of the symbol.

1-2-6. Symbol Detection Process

At a sixth step, the server device 10-1 detects the symbol from the plant drawing (Step S6). For example, the server device 10-1 searches the acquired plant drawing information, and detects the symbol having the symbol pattern that is matched with or similar to the specified symbol pattern. At this time, the server device 10-1 generates symbol detection information that includes a symbol detection drawing that is a highlighted plant drawing obtained by coloring the detected symbol, and stores the generated symbol detection information. Furthermore, the server device 10-1 generates the symbol detection information that includes a symbol detection list that indicates a list of detected symbols, and stores the generated symbol detection information.

The server device 10-1 may detect the symbol by using a detection model DM that is a machine learning model, and, in the case where a detection mistake, such as a detection omission or erroneous detection, has been made in the symbol detection information, the server device 10-1 may notify the plant administrator O of the detection mistake.

1-2-7. Symbol Detection Information Transmission Process

At a seventh step, the server device 10-1 transmits the symbol detection information to the plant administrator terminal 20 (Step S7). For example, the server device 10-1 transmits the symbol detection information that includes the symbol detection drawing and the symbol detection list to the plant administrator terminal 20.

1-2-8. Symbol Detection Information Displaying Process

At an eighth step, the plant administrator terminal 20 displays the symbol detection information (Step S8). For example, the plant administrator terminal 20 displays the symbol detection drawing that is included in the received symbol detection information on the monitor screen. Furthermore, the plant administrator terminal 20 may also display the symbol detection list that is included in the received symbol detection information on the monitor screen.

1-3. Overall Effect of Information Providing System 100-1

In the following, a background of the plant drawing, an outline associated with and the point at issue in the reference technology will be described, and then, the effect of the information providing system 100-1 will be described.

1-3-1. Background of Plant Drawing

In recent years, a technology related to a plant has been drawing attention. For example, the software market of international plant engineering has expanded every year, and further expansion is expected. For construction, operation, and maintenance of the plant, a plant drawing, such as a building diagram, a layout drawing, a P&ID, or an IBD, of the plant is used.

Here, historical circumstances of a plant drawing will be described by using a P&ID that is a plant drawing as an example. First, in an introduction period or in a spread period of the plant drawing, a paper P&ID is used; then, a P&ID generated by a two-dimensional Computer-Aided Design (CAD) generated by digital data is used; subsequently, an intelligent P&ID in which tag information or the like related to a plant instrument is added is used; and in the future, next generation of intelligent P&ID that is a further efficient plant drawing is presumed to be used. In recent years, a technique for the P&ID is being transitioned from the paper P&ID or the P&ID generated by a two-dimensional CAD to the intelligent P&ID.

In a process of construction, operation, and maintenance of the plant, there is a need to generate a list of the instruments and materials illustrated in the plant drawing, such as a building diagram, a layout drawing, a P&ID, an IBD, or the like, of the plant. However, for example, in the case where the plant drawing is a P&ID generated by a two-dimensional CAD, there is a need for an engineer to visually detect a symbol associated with an instrument or a material from the plant drawing, which is inefficient, and a human error tends to occur.

Accordingly, there is a demand for a technology for registering a pattern of a desired symbol from among a plurality of symbols that are present in the plant drawing that is used for construction, operation, and maintenance of the plant, detecting all of the symbols each having a shape or the like that is matched with the shape or the like of the registered pattern from the plant drawing, and providing the detected symbol.

1-3-2. Outline of Reference Technology

Here, the outline associated with the reference technology related to the plant drawing will be described. In the following, a reference technology 1 that allows for automatic structuring of a raster format drawing, and a reference technology 2 that is a technology for structuring a drawing capable of improving recognition accuracy of the symbols depicted in a drawing will be described.

The reference technology 1 structures structural elements by converting, as vector conversion, a raster format drawing to a vector format drawing, holding a structured rule definition database in which a rule that is used at the time of structuring of the structural elements that are included in the vector format drawing, and adding, by referring to the structured rule definition database, attribute information and connection information to the structural elements that are included in the vector format drawing.

The reference technology 2 structures a vector format drawing by holding a structured rule definition database that stores therein a rule for defining attribute information that indicates an attribute of each of the symbols and a connection relation between each of the symbols and respective line segments, recognizing the symbols that are depicted in the raster format drawing, converting the raster format drawing to the vector format drawing, arranging the symbol that has been specified on the basis of the recognition result of the symbols in the vector format drawing, and adding the attribute information to each of the symbols by using the attribute information and the rule that are stored in the structured rule definition Database.

1-3-3. Point at Issue of Reference Technology

However, in the technologies of the reference technology 1 and the reference technology 2, there is a problem in that it is difficult to register the pattern of the desired symbol from among the plurality of symbols that are present in the plant drawing that is used for construction, operation, and maintenance of the plant, detect all of the symbols each having a shape or the like that is matched with the shape or the like of the registered pattern from the plant drawing, and provide the detected symbols. Furthermore, there is also a known detection technology for detecting a symbol from a plant drawing, such as a P&ID, generated by the two-dimensional CAD by using a machine learning model, but there is a problem in that detection accuracy is low.

1-3-4. Outline of Information Providing System 100-1

The information providing system 100-1 includes the server device 10-1 that is the information providing device and the plant administrator terminal 20 that is used by the plant administrator O. The server device 10-1 receives drawing data on the plant drawing generated by using each of the symbols that indicate the plurality of respective components that constitute the plant, accepts selection of an arbitrary component from among the plurality of components from the plant administrator terminal 20, detects, on the basis of the symbol pattern of the symbol that indicates the selected component, from each of the symbols included in the plant drawing, the symbols having symbol patterns that are matched or similar each other, and transmits the symbol detection information related to the detected symbol to the plant administrator terminal 20. At this time, the server device 10-1 transmits, as the symbol detection information, a symbol detection drawing that is a highlighted plant drawing obtained by coloring the detected symbols and a symbol detection list that indicates a list of the detected symbols, and causes the monitor screen of the plant administrator terminal 20 to display the detection result.

1-3-5. Effects

The information providing system 100-1 is able to efficiently detect the symbols of the instruments and the materials from the plant drawing that is used for construction, operation, and maintenance of the plant, and provide the detected symbols to the plant administrator O, a plant engineer, a plant construction business person, or the like who is a user of the plant drawing. Furthermore, in the information providing system 100-1, it is possible to implement pattern extraction with further high accuracy as compared to a symbol detection technology that uses only the machine learning model.

As described above, in the information providing system 100-1, it is possible to efficiently provide the information related to the symbols from the drawing that is related to the plant, so that it is possible to expect to contribute to a development of the plant related technology whose market is expanding.

Furthermore, the connection element mentioned here indicates piping (e.g.: piping through which a fluid flows) or wiring (e.g.: wiring through which electricity flows) that connects the plant instruments that constitutes the plant, the plant facilities, and the like.

1-2-4. Line Selection Information Transmission Process

At a fourth step, the plant administrator terminal 20 transmits line selection information to the server device 10-2 (Step S14). For example, the plant administrator terminal 20 transmits identification information on the line associated with the piping selected by the plant administrator O or positional information on the position of the line illustrated in the plant drawing to the server device 10-2.

1-2-5. Line Pattern Registration Process

At a fifth step, the server device 10-2 registers a line pattern (Step S15). For example, the server device 10-2 acquires the plant drawing information on the basis of the line selection information received from the plant administrator terminal 20, and specifies the line pattern from the digital data on the line associated with the corresponding piping. At this time, the server device 10-2 stores the specified line pattern as line pattern information.

Here, the line pattern indicates the identification information for identifying the shape of a line, and is, for example, a thickness, a line type, a color, or the like of the line.

1-2-6. Line Detection Process

At a sixth step, the server device 10-2 detects the line from the plant drawing (Step S16). For example, the server device 10-2 searches the acquired plant drawing information, and detects the line having the line pattern that is matched with or similar to the specified line pattern. At this time, the server device 10-2 generates line detection information that includes a line detection drawing that is a highlighted plant drawing obtained by coloring the detected line, and stores the generated line detection information. Furthermore, the server device 10-2 generates the line detection information that includes a line detection list that indicates a list of the detected lines, and stores the generated line detection information.

The server device 10-2 may detect the line by using the detection model DM that is the machine learning model, and, in the case where a detection mistake, such as a detection omission or erroneous detection, has been made in the line detection information, the server device 10-2 may notify the plant administrator O of the detection mistake.

1-2-7. Line Detection Information Transmission Process

At a seventh step, the server device 10-2 transmits the line detection information to the plant administrator terminal 20 (Step S17). For example, the server device 10-2 transmits the line detection information that includes the line detection drawing and the line detection list to the plant administrator terminal 20.

1-2-8. Line Detection Information Displaying Process

Furthermore, in the case where {line angle information: “detect exact matched line”} has been accepted as the detection condition that is used at the time of detection of the line associated with the piping “P7017” included in the “plant drawing PD001”, the detection unit 15c further detects the line having the line angle of “180°” from among the lines having the line patterns that are matched or similar each other.

Furthermore, in the case where {line number information: “detect line including line number”} has been accepted as the detection condition that is used at the time of detection of the line associated with the piping “P7017” included in the “plant drawing PD001”, the detection unit 15c further detects the line having the line number of “P7017 B1 H30” from among the lines having the line patterns that are matched or similar each other.

For example, the detection unit 15c generates, as the line detection information, the line detection drawing that is the configuration diagram in which the detected lines are highlighted. Furthermore, the detection unit 15c generates the line detection list that is a list of the detected lines. Furthermore, the detection unit 15c stores the generated line detection information in the line detection information storage unit 14f.

As a specific example of the line detection drawing, the detection unit 15c acquires the plant drawing information on the “plant drawing PD001” from the plant drawing information storage unit 14a, generates, as the line detection drawing, the plant drawing information on the “plant drawing PD001” that is highlighted by coloring the line associated with the detected piping “P7017” in blue, and stores the obtained data in the line detection information storage unit 14f.

For example, the detection unit 15c connects the detected symbol and the detected line as the flow direction detection information, and generates a flow direction detection drawing that is the configuration diagram in which the curve with the arrow that indicates the flow direction is displayed by being superimposed on the symbol and the line. Furthermore, the detection unit 15c generates, as the flow direction detection information, a flow direction detection list that is a list of the detected symbols, the detected lines, and the flow direction. Furthermore, the detection unit 15c stores the generated flow direction detection information in the flow direction detection information storage unit 14g.

As a specific example of the flow direction detection drawing, the detection unit 15c acquires the plant drawing information on the “plant drawing PD001” from the plant drawing information storage unit 14a, highlights the symbol associated with the detected control instrument “FC7100” and the line associated with the detected piping “P7017” by coloring the symbol and the line in blue, and, furthermore, generates, as the flow direction detection drawing, the plant drawing information on the “plant drawing PD001” in which the curve with the blue arrow that indicates the flow direction of the fluid or the signal flowing through the symbol associated with the control instrument “FC7100” and the line associated with the piping “P7017” are superimposed on the symbol and the line, and stores the generated flow direction detection drawing in the flow direction detection information storage unit 14g.

As a specific example of the line detection list, the detection unit 15c generates {“FC7100-6”→“P7017-2”→“FC7100-6”, and . . . } as the flow direction detection list corresponding to the list of the connection relation between the symbol associated with the control instrument “FC7100” and the line associated with the piping “P7017” and the list of the flow directions of the fluids or the signals, and stores the generated flow direction detection list in the flow direction detection information storage unit 14g.

2-2-2-4. Providing Unit 15d

The providing unit 15d performs the flow direction detection information transmission process. For example, the providing unit 15d transmits the flow direction detection information that is the detection result related to the flow direction that has been detected by the detection unit 15c to the plant administrator terminal 20.

As a specific example, the providing unit 15d highlights the detected symbol associated with the control instrument “FC7100” and the detected line associated with the piping “P7017” by coloring the symbol and the line in blue as the flow direction detection information, and, furthermore, transmits, to the plant administrator terminal 20 that is used by the plant administrator O identified by the “plant administrator PO001”, the flow direction detection drawing of the “plant drawing PD001” in which the curve with the blue arrow that indicates the flow direction of the fluid or the signal that flows through the symbol associated with the control instrument “FC7100” and the line associated with the piping “P7017” is displayed by being superimposed on the symbol and the line, the connection relation of the symbol associated with the control instrument “FC7100” and the line associated with the piping “P7017”, and the flow direction detection list {“FC7100-6”, “P7017-2”→“FC7100-6”, and . . . } that indicates the flow direction of the fluid or the signal.

The notification unit 15e performs the output result acquisition process, the detection mistake notification process, and the like.

Output Result Acquisition Process

The notification unit 15e acquires an output result by using the trained machine learning model that outputs the flow direction included in the plant drawing in accordance with an input of each of the digital data on the plant drawing, the symbol pattern, and the line pattern.

As a specific example, the notification unit 15e inputs plant drawing information on the “plant drawing PD001”, the symbol pattern {diagram: “circle/line segment/square”, line type: “solid line”}, and the line pattern {thickness: “1.0 pt”, line type: “solid line”} to the detection model DM included in the detection model storage unit 14d, and acquires {“FC7100-6”→“P7017-2”→“FC7100-6” →“P7017-3”→“FC7100-4”, and . . . } that is the output result of the detection model DM.

Detection Mistake Notification Process

The notification unit 15e notifies the plant administrator O of a detection omission or erroneous detection of the flow direction obtained by using the output result of the trained machine learning model.

As a specific example, the notification unit 15e compares the flow direction detection list {“FC7100-6”→“P7017-2”→“FC7100-6”, and . . . } that has been detected by the detection unit 15c with {“FC7100-6”→“P7017-2”→“FC7100-6”→“P7017-3”→“FC7100-4”, and . . . } that is the output result of the detection model DM, determines a possibility of a detection omission of the flow direction between the line associated with the piping “P7017” that is the identification information “P7017-3” and the symbol associated with the piping “FC7100” that is the identification information “FC7100-4”, generates a message indicating that “There is a possibility of a detection omission.”, or the like as the detection mistake information, and transmits the generated detection mistake information to the plant administrator terminal 20 that is used by the plant administrator O identified by the “plant administrator PO001”.
