With such a configuration, the user can easily grasp where the element group to be registered exists.

In the information processing apparatus according to one embodiment, when the registered element group is represented by the first notation rule and the target drawing is represented by the second notation rule, the control unit converts the data of the registered element group to the After converting to the second notation rule, it is used for the target drawing. In this way, even if the notation rules of the registered element group and the notation rule of the target drawing are different, the notation rule of the registered element group is converted according to the target drawing and then the above-mentioned processing is performed, so the user does not have to set the notation rule. It is possible to more easily grasp the element group to be registered without being particularly conscious of the difference.

In the information processing apparatus according to one embodiment, the control unit causes the display unit to display the data of the registered element group before converting the data of the registered element group into the second notation rule. With such a configuration, the user can grasp the data of the registration element group before conversion.

In the information processing apparatus according to one embodiment, the control unit further causes the display unit to display the registered element group after converting the data of the registered element group into the second notation rule. With such a configuration, the user can grasp the data of the registered element group after conversion and the data of the registered element group before conversion so as to be able to compare them.

A connection method between the display unit 11 and the information processing device 10 may be any connection method. For example, the connection method is USB (Universal Serial Bus), HDMI (registered trademark) (High-Definition Multimedia Interface), or Bluetooth (registered trademark). However, the display unit 11 may be provided in the information processing device 10 .

Information generated by the information processing apparatus 10 will be described below as being displayed on the display unit 11 . However, the information generated by the information processing device 10 may be displayed on the display unit of another terminal device such as the terminal device 20 or the terminal device 30 .

The input unit 12 includes at least one input interface capable of accepting input operations from the user. The input interface may be a physical key, a capacitive key, a pointing device, a touch screen integrated with the display, a microphone, or the like. The input unit 12 is connected to the information processing device 10 as an external input device. The connection method between the input unit 12 and the information processing device 10 may be any connection method. For example, the connection method is USB, HDMI (registered trademark), Bluetooth (registered trademark), or the like. However, the input unit 12 may be provided in the information processing device 10 .

In the following description, it is assumed that the input unit 12 receives an input operation from the user. However, the input operation from the user may be received by other terminal devices such as the terminal device 20 and the terminal device 30 .

The communication unit 13 includes at least one communication module. The communication module is, for example, a module compatible with standards such as wired LAN (Local Area Network) or wireless LAN. The control unit 15 communicates with the terminal device 20 , the terminal device 30 and the external storage device 40 via the network 2 through the communication unit 13 .

The storage unit 14 includes at least one semiconductor memory, at least one magnetic memory, at least one optical memory, or a combination of at least two of them. The semiconductor memory is, for example, RAM (Random Access Memory) or ROM (Read Only Memory). RAM is, for example, SRAM (Static Random Access Memory) or DRAM (Dynamic Random Access Memory). The ROM is, for example, an EEPROM (Electrically Erasable Programmable Read Only Memory) or the like. The storage unit 14 may function as a main storage device, an auxiliary storage device, or a cache memory. The storage unit 14 stores data used for the operation of the information processing device 10 and data obtained by the operation of the information processing device 10 .

The storage unit 14 stores drawing data, notation rules, element group lists, semantic models, and the like. A part or all of the information stored in the storage unit 14 may be stored in the external storage device 40 .

The drawings are used, for example, for construction, operation, maintenance, repair, etc. of a process control system in a plant or the like. The drawings are, for example, P&IDs, PFDs, equipment lists, equipment setting information, CAD drawings, control logic diagrams, simulation models or graphic drawings. An example in which the configuration according to the present embodiment is applied to a drawing showing a plant will be described below, but the configuration is not limited to this and may be applied to various drawings as long as it is a drawing consisting of elements.

The drawings are represented by multiple elements. Elements correspond to equipment such as, for example, pumps. In the drawings, element types, element attribute information, and element arrangements are defined. The element attribute information is information indicating at least one of the properties of the element and the operating conditions of the element. The information indicating the property of the element is, for example, information indicating the model number of the device corresponding to the element, information about setting values set in the device corresponding to the element, information indicating the material of the element, and the like. The information indicating the material of the element is, for example, information such as stainless steel when the element type is a tank. The information indicating the operating condition of the element is information indicating the condition for causing the element to perform a specific operation. For example, if the type of element is a tank, the information indicating the operating condition of the element indicates a condition such that some kind of control is performed when the amount of content in the tank exceeds a predetermined value (for example, 500 liters). Information. Attribute information is assigned to each element in the drawing. In addition, in a drawing, it is possible to determine which is upstream and which is downstream from the positional relationship of the elements on the drawing. Alternatively, the arrangement information of elements is predetermined. The arrangement information of the elements is information indicating which of the two elements connected to each other in the drawing exists upstream or downstream. The element arrangement information may be stored in the storage unit 14 separately from the drawing data. The element array information is, for example, From/To information in digital P&ID.

Drawing data includes element symbol data. Symbols of the elements are represented by graphics, for example, and are represented by combining at least one of letters and colors as appropriate. For example, as shown in FIG. 2, to which reference will be made later, the symbol for element B is represented by the letter "B" and a circular figure. In addition, the drawing data includes data of an element group consisting of at least one element. An element group is a collection of elements consisting of at least one element used in at least one drawing. A group of elements is also displayed as a “group” on the display unit 11 .

Notation rules define rules for representing elements as symbols in drawings. Element symbols differ depending on the standard, drawing type, tool type, drawing version or plant operator. A notation rule for each different drawing is stored in the storage unit 14 .

The element group list is information indicating at least one element group, and includes information on registered element groups as described later. The information of the registered element group includes, for example, identification information of the registered element group, the type of each element included in the registered element group, array information indicating the arrangement of the elements included in the registered element group, and each element included in the registered element group. Contains attribute information of the element.

The semantic model is used when the control unit 15 retrieves the element group from the drawing and when the control unit 15 analyzes the element group. The semantic model represents a drawing used in the process control system with first information indicating elements included in the drawing and second information indicating relationships between the elements. A semantic model is generated, for example, by converting a drawing used in a process control system according to a predetermined conversion rule. A predetermined conversion rule may be set for each type of drawing. Note that the control unit 15 appropriately analyzes the elements that make up the element group or the connections between the elements using pattern matching, image recognition, graph theory, ontology, or the like, thereby searching for the element group from the drawing, or finding the element group. may be analyzed. Information used for searching and analyzing such element groups is stored in the storage unit 14 .

The control unit 15 includes at least one processor, at least one dedicated circuit, or a combination thereof. The processor is a general-purpose processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit), or a dedicated processor specialized for specific processing. The dedicated circuit is, for example, FPGA (Field-Programmable Gate Array) or ASIC (Application Specific Integrated Circuit). The control unit 15 executes processing related to the operation of the information processing device 10 while controlling each unit of the information processing device 10 .

<Registration process>
The control unit 15 receives a user operation such as designating an element group (group) by selecting a part of the drawing to be displayed on the display unit 11 through the input unit 12 . When the input unit 12 receives this user operation, the control unit 15 acquires from the storage unit 14 the data of the element group that is a part of the drawing specified by the user operation. When acquiring the drawing data, the control unit 15 causes the display unit 11 to display the image of the drawing. For example, the control unit 15 causes the display area 11A of the display unit 11 to display an image of a drawing showing the configuration of the plant, as shown in FIG.

The control unit 15 may receive, through the input unit 12, an instruction to shift to a mode in which a group of elements in the drawing can be selected by a user operation. Upon receiving this instruction, the control unit 15 may shift the mode of the information processing apparatus 10 to a mode in which a group of elements in the drawing can be selected by a user operation.

The control unit 15 receives a user operation for selecting an element group in the drawing through the input unit 12 . For example, as shown in FIG. 2, the user selects an element group located in area 50 by selecting area 50 in the drawing with touch operation 3 . The element group selected by the user is, for example, a group of elements that perform a certain function. The group of elements located in region 50 consists of the valve, element A and element B elements. The user selects a group of elements for batch processing in subsequent processing. Batch processing is, for example, processing for collectively executing editing or correction of a group of elements on a plurality of identical groups of elements (groups) existing in a drawing. Note that the operation of selecting an element group from a drawing is not limited to the touch panel operation. An operation of selecting an element group from a drawing may be performed by an operation of moving a cursor or the like using a pointing device such as a mouse, trackball, or touch pad.

The control unit 15 registers the selected element group by storing the information of the element group selected by the user operation in the storage unit 14 . In this embodiment, the control unit 15 registers the selected element group by adding information on the selected element group to the element group list. Hereinafter, a registered element group is also referred to as a "registered element group" ("registered group"). The control unit 15 may generate identification information for each registered element group when adding information on the selected element group to the element group list.

The control unit 15 may cause the display unit 11 to display information on the registered element group. For example, the control unit 15 displays an image 60 representing the registered element group and an image 61 representing information of each element constituting the registered element group, ie, component element information, in the display area 11B of the display unit 11 as shown in FIG. You may let In FIG. 2, the identification information of the registered element group is displayed as "registered group No. 002". The display area 11B may be used as a UI (User Interface) for the user to refer to information about the element group and perform operations such as editing, information analysis, screen transition, and the like. Information displayed in the display area 11B as shown in FIG.

<Search process>
The control unit 15 executes search processing for searching the drawing for an element group that matches the element group selected by the user's operation. The control unit 15 may execute the search process in response to the user selecting the element group by selecting the area 50 as shown in FIG. Hereinafter, the element group selected by user operation is also described as "search element group"("searchgroup"). A group of search elements becomes a group of registered elements when registration processing has already been executed. Elements that match search elements are also referred to as "matching elements"("matchinggroups"). Note that the control unit 15 may search for element groups (hit element groups) existing in the drawing to be processed among registered element groups included in the existing element group list as search element groups. Details will be described in a second embodiment.

For example, in the configuration shown in FIG. 3, the search element group is the element group located in area 50 . This search element group consists of three elements: valve, element A, and element B. In this search element group, the most upstream is the valve, the element A is connected downstream of the valve, and the element B is connected downstream of the element A.

The control unit 15 detects an element group that satisfies the compatibility condition of the element group as a compatible element group. The compatibility condition for the element group may be set as appropriate. A matching condition for a group of elements is, for example, a group of elements composed of the same elements as the elements constituting the group of search elements, regardless of the attribute information attached to the elements, and the arrangement of the elements of the group of elements is It may be the same as the array of elements in the element group. Alternatively, the matching condition of the element group is, for example, that in addition to the type and arrangement of the elements that make up the element group, the attribute information attached to the element (required items) match the elements of the search element group (or ) may be used. In other words, the compatibility condition of the element group may include that the attribute information attached to each element constituting the element group is compatible.

If an element in the drawing satisfies the matching condition of the element, the control unit 15 detects that element as an element matching the elements of the search element group. The compatibility condition of the element is, for example, that the element is of the same type as the element type of the search element group and to which the same attribute information as that of the element of the search element group is assigned. The control unit 15 may acquire information on matching conditions for element groups stored in the storage unit 14 . Further, the control unit 15 may receive from the input unit 12 the matching condition of the matching element group. Since there may be attribute information that does not always need to match, it may be specified as appropriate which attribute information should match to what degree as a matching condition. The conditions may be appropriately designated by the user, or may be conditions set in advance and stored in a rule storage section (not shown) in the storage section 14 or the like. Further, the user may appropriately change the rules stored in the storage unit 14 and use them.

Specifically, first, the control unit 15 searches the drawing for an element matching the first element among the elements of the search element group. The first element is, for example, the element positioned most upstream among the elements of the search element group. However, the first element may be set as appropriate. For example, the first element may be set by the user, or may be an element playing an important role among the elements of the drawing or search element group. Alternatively, the first element may be appropriately set based on a predetermined rule stored in the storage unit 14 (for example, a rule that determines which element in the drawing should be searched with priority). For example, in the search element group as shown in FIG. 3, the first element is the valve. That is, in the configuration shown in FIG. 3, the control unit 15 searches for valves.

Next, after retrieving an element matching the first element of the search element group, the control unit 15 determines whether or not there is an element matching other elements other than the first element of the search element group. Specifically, based on the arrangement information of the elements, the control unit 15 determines whether an element adjacent to the element matching the first element matches the second element of the search element group. The second element is an element adjacent to the first element in the search element group. The second element is the element connected downstream of the first element when the first element is the most upstream element. For example, the second element is element A in the search element group as shown in FIG. When the control unit 15 determines that the element adjacent to the element matching the first element matches the second element, the element adjacent to the element matching the second element is included in the search element group based on the arrangement information of the elements. It is determined whether or not it conforms to the third element of The third element is an element different from the first element among the elements adjacent to the second element in the search element group. For example, the third element is element B in the search element group as shown in FIG. By sequentially repeating such processing, the control unit 15 determines whether or not there is an element that matches the elements other than the first element of the search element group.

In this way, the control unit 15 searches for an element matching the first element in the search element group. Next, starting from the first element, the control unit 15 sequentially determines whether or not there is an element matching other elements of the search element group. Therefore, as soon as an element that does not match the elements of the search element group is found, the process of matching that element with the search element group is interrupted. As a result, processing can be made more efficient.

The control unit 15 determines that there are elements that match the elements other than the first element of the search element group and that they exist in the same arrangement as the search element group (furthermore, necessary attribute information attached to each element is match), an element group composed of elements that match the elements of the search element group is detected as a matching element group. In the configuration shown in FIG. 3, the control unit 15 detects element groups 51 and 52 as matching element groups. In addition, in the element group 53, the element C is connected to the downstream side of the element A. As a result, the control unit 15 does not detect the element group 53 as a matching element group.

Note that the matching conditions for the element group are not limited to those described above. As another example, the matching condition of the element group may be a condition that the element type and arrangement of the element group are the same as the element type and arrangement of the search element group. In this case, if the type and arrangement of the elements of the element group are the same as the type and arrangement of the elements of the search element group, the control unit 15 sets the attribute information of the elements of the element group to the attribute information of the elements of the search element group. Detects the elements as conforming elements even if they are not the same as . Such a compatibility condition may be changed by a user's setting change or selection as appropriate.

The control unit 15 causes the storage unit 14 to store information on the detected matching element group. The control unit 15 causes the storage unit 14 to store the information of the matching element group in association with the information of the registered element group. The matching element group information may include location information of the matching element group. The positional information of the element group is, for example, the page number of the drawing to be divided or the number of the drawing, the layer number, the coordinates specifying the location of the element group, the piping or wiring on which the element group exists, and the reference piping, etc. It may be at least any of the information such as what order it is. When a plurality of drawings are superimposed, the layer number indicates the order in which the drawing is superimposed from the reference drawing. By storing the position information of the matching element group, the information processing apparatus 10 can use the information of the element group that has been searched once without re-searching.

The control unit 15 may cause the display unit 11 to display the detected matching element group in a display mode different from that of the other elements. For example, as shown in FIG. 4, the control unit 15 causes the display area 11A of the display unit 11 to display the search element group of the area 50 and the element groups 51 and 52, which are matching element groups, in a display mode different from the others. . The different display mode may be displaying in a color different from others, or displaying with a specific mark. The control unit 15 may display the conforming element group by changing the line type, adding a symbol, or adding information specifying the element group such as an element group number or an element group name. With such a configuration, the user can easily recognize the searched matching element group in the drawing displayed on the display unit 11 .

The control unit 15 may cause the display unit 11 to display the number of detected matching element groups. For example, the control unit 15 causes the display area 11C of the display unit 11 as shown in FIG. 4 to display that there are three matching element groups in the drawing displayed in the display area 11A as currently displayed. In addition, the control unit 15 causes the display area 11C to display that there are 45 matching element groups in the entire drawing including other pages not displayed in the display area 11A.

The control unit 15 may cause the display unit 11 to display an image showing the distribution of the applicable element group existing in the drawing of the entire plant. For example, as shown in FIG. 4, the control unit 15 displays the existing area distribution in the display area 11D of the display unit 11 as an image showing the distribution of the applicable element group existing in the drawing of the entire plant. A frame 62 indicates the portion displayed in the display area 11A of the drawing of the entire plant. Each of the rectangles 63, 64, 65 corresponds to a portion of the drawing of the entire plant where the matching element group exists. Ten matching element groups exist in the portion corresponding to the rectangle 63, and three of the ten locations are displayed in the display area 11A. A portion corresponding to the rectangle 64 has 15 conforming element groups. There are 20 conforming element groups in the portion corresponding to the rectangle 65 . By referring to the image showing the distribution of the matching element groups existing in the drawing of the entire plant on the display unit 11, the user can easily grasp where the matching element group exists in the drawing. Such a display is useful when you want to work on a certain group of elements in the design and maintenance of drawings. Such operations are, for example, correction of elements or confirmation of the distribution of a group of compatible elements. Note that the control unit 15 may perform the search processing in a specific range selected by the user in the drawing of the entire plant instead of the drawing of the entire plant.

Note that, when a search element group is selected, the control unit 15 automatically creates a matching element group that matches the search element group without an explicit search or search result registration instruction from the user. You can search from Furthermore, the control unit 15 may cause the storage unit 14 to store the position information of the matched element group found. With such a configuration, the user can use the search results as needed. For example, a user can easily select a search element group by operating the terminal device 20 or the terminal device 30 as shown in FIG. In addition, the automatically stored search result information can be used.

FIG. 5 is a flow chart showing an example of the procedure of the element group registration process and the element group search process of the information processing apparatus 10 shown in FIG. When the input unit 12 receives a user operation for specifying a drawing, the control unit 15 causes the display unit 11 to display the data of the drawing specified by the user operation, and then starts the processing shown in FIG. The information processing method including the procedure as shown in FIG. 5 may be implemented as a program to be executed by the processor of the information processing device 10 . This program may be stored in a non-transitory computer-readable medium.

The control unit 15 receives a user operation for selecting an element group (group) in the drawing through the input unit 12 (step S10). The control unit 15 registers the selected element group by storing the element group selected by the user operation in the storage unit 14 (step S11).

The control unit 15 sets the element group registered in step S11 as a search element group (search group), and searches the drawing for an element matching the first element among the elements of the search element group (step S12).

After retrieving an element matching the first element of the search element group, the control unit 15 determines whether or not there is an element matching other elements other than the first element of the search element group (step S13). If the control unit 15 determines that there is an element that matches the element other than the first element of the search element group (step S13: YES), the process proceeds to step S14. On the other hand, if the control unit 15 determines that there is no element that matches the element other than the first element of the search element group (step S13: NO), it ends the search process.

In the process of step S14, the control unit 15 detects an element group composed of elements that match the elements of the search element group as a matching element group (matching group).

In the processing of step S15, the control unit 15 causes the storage unit 14 to store information on the matching element group.

In the processing of step S16, the control unit 15 causes the display unit 11 to display the matching element group in a display mode different from that of the other elements.

In the processing of step S17, the control unit 15 causes the display unit 11 to display an image showing the distribution of the applicable element groups existing in the drawing of the entire plant.

Note that the drawing to be searched for the matching element group may not be one drawing, but may be a plurality of drawings. Also, the target drawing for searching for the matching element group may be a drawing relating to the same plant or a drawing relating to a plurality of different plants.

As described above, in the information processing apparatus 10 according to the first embodiment, the control unit 15 receives a user operation for selecting an element group in the drawing through the input unit 12 . Furthermore, the control unit 15 executes search processing for searching for a matching element group using the element group selected by the user as a search element group. As described above, in the information processing apparatus 10, a matching element group that matches the element group selected by the user's operation is automatically retrieved. As a result, the user can easily extract all element groups matching a specific element group from the drawing with a small number of man-hours. Furthermore, the information processing apparatus 10 can accept selection of an element group from the display unit 11 that displays the drawing. Such a configuration allows the user to easily select the element group. Therefore, according to the present embodiment, it is possible to improve the efficiency of the work of selecting element groups in a complicated and huge number of drawings, reduce work time and personnel costs, and reduce work mistakes.

(Second embodiment)
By executing the registration process and the like described in the first embodiment, the storage unit 14 stores an existing element group list generated (selected and specified in an existing drawing) for a drawing related to an existing plant. become. In the second embodiment, a configuration for generating a new element group list using such an existing element group list will be described. A new element group list is generated, for example, by designating an element group (group group) to be processed with respect to a drawing of a plant that is currently being processed. Hereinafter, the plant for which a new element group list is generated is also referred to as the "target plant". Drawings used in the process control system of the target plant are also referred to as "target drawings."

<Candidate plant selection process>
The control unit 15 selects at least one candidate plant from among a plurality of existing plants based on the target drawing, the existing drawing, and the element group list registered for the existing drawing, which are stored in the storage unit 14. do. A candidate plant may be selected, for example, in response to an instruction to create a new group list being received by the input unit 12 . An "existing plant" is a plant for which existing drawings are used in its process control system. A "candidate plant" is a plant selected from existing plants and represented by an existing drawing whose element group list is reused for the target drawing. As will be described later, the candidate plant is subjected to provisional application processing.

FIG. 6 is a diagram showing an example of basic information of an existing plant and a target plant. For example, a plurality of plants including plants P1 to P4 as shown in FIG. 6 are existing plants. Figure 6 shows an example of basic information about existing plants and target plants, including plant type (for example, product), operating company (or design company, etc., involved companies/organizations, etc.), design time, and plant Although information such as scale is shown, there is a wide variety of information, and the basic information is not limited to these. Moreover, FIG. 6 is an example, and actually there may be more plants and related drawing data. It is generally difficult for a user to select a specific plant from basic information consisting of a large number of items about such a large number of plants by viewing the information or judging the information. Therefore, the control unit 15 automatically selects, as a candidate plant, a plant that is highly similar to the target drawing, which is the drawing of the target plant that is currently being processed (the drawing is also highly similar). In the example of FIG. 6, the control unit 15 selects at least one candidate plant from among a plurality of plants including plants P1 to P4.

The control unit 15 selects a candidate plant based on the comparison result between the basic information of the existing plant and the basic information of the target plant. The basic information of the plant is information on basic items related to the design of the process control system of the plant. The items of the basic information of the plant are items that have a high possibility of affecting the configuration and elements of the element group in the drawing. In other words, the comparison result between the basic information of the existing plant and the basic information of the target plant shows which of the registered element groups registered in the drawing related to the existing plant is closer to the element group included in the target drawing (element group It can be a material for judging whether the inclusion rate is high. The control unit 15 may acquire the basic information of the plant stored in the storage unit 14 . The control unit 15 may receive and acquire the basic information of the existing plant through the communication unit 13 from an external device via the network 2 . The control unit 15 may receive basic information about the target plant from the input unit 12 .

The basic information includes, as shown in FIG. 6, the plant type of each plant (for example, products manufactured at the plant), the operating company that operates the plant, the design time when the plant was designed, the plant scale, and the like. The plant scale may be divided into multiple stages. Plant scales are, for example, three stages of small scale, medium scale and large scale. Here, the configuration of the group of elements used in the plant, the types of elements, etc. differ depending on the type of product produced by the plant. Also, the symbol data of the elements in the drawings differ depending on the operating company of the plant (designer and tool used for design). In addition, changes and differences between new and old expressions may occur depending on the design period of the plant, and there is a possibility that the model numbers of the elements used in the plant and the symbol data of the elements in the drawings will differ. Also, the configuration and elements of the element group used in the plant differ depending on the scale of the plant. Therefore, matching of plant products, plant operating company, plant design time, plant scale, etc. is an item that has a high possibility of affecting the configuration and elements of the element group in the drawings. Of course, the basic information items and their contents shown in FIG. 6 are examples, and items other than these may be used.

The plant type (eg, product) of plant P1 is petroleum. Company X is the operator of plant P1. The design date of plant P1 is 2010. The scale of the plant P1 is small. The number of registered element groups registered in the drawing of the plant P1 is 100 pieces.

The plant type of plant P2 is petroleum. Company Y is the operator of plant P2. The design date for plant P2 is 2015. The scale of plant P2 is large. The number of registered element groups registered in the drawing of the plant P2 is 310 pieces.

The plant type of plant P3 is petroleum. Company X is the operator of plant P3. The design date for plant P3 is 2018. The scale of plant P3 is large. The number of registered element groups registered in the drawing of the plant P3 is 290 pieces.

The plant type of the plant P4 is chemical. Company X is the operator of plant P4. The design date for plant P4 is 2018. The scale of plant P4 is large. The number of registered element groups registered in the drawing of the plant P4 is 280 pieces.

The control unit 15 selects an existing plant having basic information highly similar to the basic information of the target plant from among the plurality of existing plants as a candidate plant. The degree of similarity of basic information is a numerical value indicating the degree of similarity of basic information of plants. The degree of similarity of basic information may be, for example, the number of items of basic information with matching contents, or the ratio of the number of items of basic information with matching contents to the total number of items. Alternatively, as the degree of similarity of basic information, the number of matching items, the degree of matching (degree of divergence) in each item, and a numerical value converted based on these may be used as appropriate. The control unit 15 may select, as a candidate plant, an existing plant whose basic information has a degree of similarity greater than or equal to a predetermined threshold. The threshold may be appropriately set based on the number of items of basic information, the number of existing plants, or the like. When the item of the basic information is the design time of the plant, the control unit 15 determines the design time of the existing plant and the design time of the target plant when the design time of the existing plant is within a predetermined number of years from the design time of the target plant. can be regarded as matching. The predetermined number of years may be appropriately set based on the frequency with which the element group of the drawing is updated. For example, in the configuration shown in FIG. 6, if the predetermined number of years is five years, the control unit 15 considers that the year 2015 when the plant P2 was designed coincides with the year 2020 when the target plant was designed. Alternatively, if there is a change in drawing standards, expression rules, etc. at a certain time, and new and old (differences in format) occur at that time, it may be divided according to such time. Since the degree of importance of each item of the basic information is not uniform, the similarity may be calculated by assigning a weight to each item according to the degree of importance. For example, if the closer the plant type (e.g. product) is, the more the drawings tend to match, set the weighting so that the plant type (product) is emphasized in the similarity calculation. You can If there are circumstances in which a certain operating company or design company has many unique designs that are difficult to refer to for other general plants, avoid existing plants involving such companies (for example, lower the priority ). If a certain item matches a certain condition, the plant may be excluded from the candidate plants, or the numerical value (score) of the degree of similarity at the time of plant comparison may be lowered.

For example, in the example of FIG. 6, the control unit 15 selects plant P2, plant P3 and plant P4 as candidate plants from a plurality of existing plants including plants P1 to P4.

Thus, the candidate plant is selected based on the result of comparison between the basic information of the existing plant and the basic information of the target plant. With such a configuration, the registered element group registered in the drawing related to the candidate plant extracted from among many plants as being more similar to the target plant is the same as the element group existing in the target drawing. exist or are likely to be similar. Therefore, it is possible to efficiently detect a hit element group, which will be described later, from the existing element group list of the candidate plant.

<Procedure for provisional application>
The control unit 15 executes provisional application processing for detecting hit element groups from registered element groups in existing element group lists of a plurality of candidate plants. The hit element group is an element group that matches the element group that exists in the target drawing of the target plant.

The control unit 15 detects, as a hit element group, an element group that satisfies the matching condition of the element group among the registered element groups of the existing element group list. The compatibility condition for the element group may be set as appropriate. The matching condition for the element group may be set similarly to the matching condition used in the search processing of the first embodiment. The compatibility condition for an element group is, for example, a registered element group composed of the same elements as each element of the element group existing in the target drawing, regardless of the attribute information attached to the element, and the element of the registered element group may be the same as the arrangement of the elements of that group of elements in the target drawing. Alternatively, the matching condition for the element group is, for example, that the types and arrangements of the elements that make up the element group are the same, and that the attribute information attached to the element (required items) is It may be matched with an element (or matched with a condition). In other words, the compatibility condition for the element group may include that all or part of the attribute information attached to each element constituting the element group is compatible. The control unit 15 may acquire information on matching conditions for element groups stored in the storage unit 14 . Further, the control unit 15 may receive the compatibility condition of the element group from the input unit 12 .

Specifically, the control unit 15 determines whether or not the registered element group of the candidate plant (the element group that has been designated in the drawing of the candidate plant in the past) exists in the drawing of the target plant. This process can be executed in the same manner as the search process described above. For example, the control unit 15 uses the registered element group of the candidate plant as the search element group, and searches the target drawing of the target plant for an element matching the first element of the registered element group of the candidate plant. When an element matching the first element of the registered element group of the candidate plant does not exist in the target drawing, the control unit 15 determines that an element group matching the registered element group does not exist in the target drawing. On the other hand, when searching for an element matching the first element of the registered element group of the candidate plant, the control unit 15 determines whether an element matching other elements other than the first element of the registered element group exists in the target drawing. determine whether If the control unit 15 determines that an element matching an element other than the first element of the registered element group exists in the target drawing, it detects the registered element group as a hit element group. The control unit 15 detects the number of hit element groups (the number of hits) by counting the detected hit element groups. Note that the control unit 15 may detect the number of hits and store information on the detected hit element group in the storage unit 14 .

In the provisional application process, it is only necessary to detect that the hit element group exists in the target drawing. Therefore, the control unit 15 does not have to search for all element groups matching the hit element group in the drawing of the target plant. With such a configuration, it is possible to efficiently execute the process of determining whether the registered element group of the existing drawing is used in the target drawing.

For example, the control unit 15 acquires a processing result as shown in FIG. 7 as a processing result of provisional application. Plant P2 has 160 hits. Plant P3 has 250 hits. Plant P4 has 90 hits.

Note that the matching conditions for the element group are not limited to those described above. As another example, the compatibility condition for the element group may be a condition that the type and arrangement of the elements of the registered element group are the same as the type and arrangement of the elements of the element group that exist in the target drawing. In this case, if the type and arrangement of the elements of the registered element group are the same as the type and arrangement of the elements of the element group of the target drawing, the control unit 15 sets the attribute information of the elements of the registered element group to the elements of the target drawing. The registered element group is detected as a hit element group even if it is not the same as the attribute information of the elements of the group.

By executing the temporary application process and detecting the number of hits in this way, it is possible to efficiently select the later-described applicable plant for executing the later-described main application process.

<Processing for this application>
The control unit 15 selects the candidate plant with the largest number of hits among the plurality of candidate plants as the "applicable plant". The control unit 15 executes the processing of this application using the hit element group of the applied plant. The process of this application is a process of retrieving an element group that matches the hit element group from the target drawing. In the processing of this application, the control unit 15 searches for all element groups matching the hit element group from the target drawing. For example, in the configuration shown in FIG. 7, the control unit 15 selects the plant P3 with the largest number of hits as the applied plant, and executes the application process using the hit element group of the plant P3.

The control unit 15 executes the processing of this application in the same manner as the search processing in the first embodiment. That is, the control unit 15 searches the hit element group of the applied plant as the search element group, and searches the target drawing of the target plant for the element group matching the search element group as the matching element group. With such a configuration, matching element groups that match the hit element group are automatically retrieved in the target drawing without the user specifying the element group. The control unit 15 causes the storage unit 14 to store the information of the matched element group searched. The control unit 15 may cause the storage unit 14 to store the position information of the matched element group searched for, as described above in the first embodiment.

The control unit 15 generates a new element group list of the target plant based on the hit element group. The control unit 15 generates an element group list of the target plant by making the hit element group of the applicable plant part or all of the registered element group of the target drawing of the target plant.

By the way, even if the processing of this application is executed using the hit element group of the applied plant, there are cases where the element group to be registered remains in the target drawing. If the target plant is a copy plant of an existing plant, which is completely or almost the same plant, or if the target plant is smaller in scale, all the element groups to be detected from the target drawing of the target plant can be found with only the hit element group. It may be covered. Otherwise, the user compensates for the difference element group by specifying it on the drawing. A "differential element group" is an element group to be registered that is included in the target drawing and is not covered by the hit element group of the applied plant. For example, in the example of FIG. 9, which will be described later, the number of registered element groups (the number of registered groups), which is the number of registered element groups to be registered in the target drawing, is 350 pieces. The number of registered element groups is the number of element groups that should be counted as a result of the actual selection, although it is not known until the element groups are actually selected from the target drawing. At the stage of applying the hit element group of the applicable plant, registration of all element groups to be extracted from the target plant is not completed, so the number of registered elements is unknown.

In this case, as shown in FIG. 9, if the number of hit element groups of the plant P3, which is the applicable plant, is 250, even if the hit element group of the applicable plant is used to execute the processing of this application, no registrations will be made in the target drawing. 100 (=350−250) registration element groups remain. Reusing hit elements from existing drawings eliminates 250 selections that otherwise would have required the user to manually select 350 elements, The user need only select 100 elements of the difference. However, as described below, existing plant registration elements may be re-used to further reduce the number of elements to be manually selected by the user.

The control unit 15 extracts an existing plant including an element group (difference element group) other than the hit element group in the target plant from among the existing plants other than the conforming plant, and classifies this as the second and third applied plants (auxiliary applied plants). plant) may perform the application process. Specifically, the control unit 15 may use a hit element group extracted by provisionally applying the auxiliary applied plant to the target plant, which does not overlap with the hit element group of the applied plant. For example, in the configuration shown in FIG. 7, the control unit 15 selects the plant P2 as a new auxiliary application plant. It is also assumed that 80 of the 160 hit element groups of the plant P2, which is the new applied plant, do not overlap with the hit element group of the previous applied plant, the plant P3. In this case, the control unit 15 uses 80 of the 160 hit elements of the plant P2 to re-execute the processing of this application. The control unit 15 adds the hit element group used in the process of the second application to the element group list of the target plant as the registered element group. By re-executing the processing of this application in this way, the number of element groups to be manually specified by the user can be further reduced, and work can be made more efficient.

For example, by executing the processing of this application, an element group list of the target plant as shown in FIG. 8 is generated. FIG. 8 shows part of the element group list of the plant P2, the plant P3 and the target plant. Element groups (element groups 101, 103, 104) corresponding to hit element groups in the element group list of plant P2 (including element groups 101 and 102) and the element group list of plant P3 (including element groups 103 to 105) is shaded. From the element group list of plant P2 shown in FIG. 8, five hit element groups 101 are added to the element group list of the target plant (element group 106). Also, from the element group list of the plant P3 shown in FIG. 8, two hit element groups 104 excluding the overlap with the element group 101 (element group 103) are added to the element group list of the target plant ( element group 107). In the case of only the element group list for plant P2, only five element groups 101 are reused in the target drawing. can be reused in the target drawing. In this way, not only a single drawing but also multiple existing drawing element group lists may be used in combination.

Note that the control unit 15 may perform the provisional application process for all existing plants without selecting candidate plants. Alternatively, this application process may be executed for all existing plants without performing temporary application. In this case, the control unit 15 executes the processing of this application using the extracted hit element group.

Also, the user may select the applicable plant. In this case, the control unit 15 causes the display unit 11 to display the processing result of the provisional application as shown in FIG. The user visually recognizes the processing result of the provisional application, selects an applicable plant, and inputs information on the selected applicable plant from the input unit 12 . The control unit 15 executes the processing of this application for the applicable plant for which the input from the user is received by the input unit 12 .

Note that the control unit 15 may acquire hit element group data from the drawing data of the applied plant, for example, for processing according to the fourth embodiment described later. In this case, the control unit 15 may use the acquired data of the hit element group as the data of the registered element group of the target drawing. Here, the notation rules differ depending on the drawing standards, versions, design companies, etc., as described above. Therefore, the control unit 15 may acquire the data of the hit element group from the data of the drawing of the applied plant, and may also acquire the notation rule applied to the drawing of the applied plant. Furthermore, the control unit 15 may convert the data of the hit element group according to the notation rule adopted for the drawing of the applied plant, and use the converted data of the hit element group as the registered element group of the target drawing.

Here, even if the processing of this application is executed for the hit element group of the candidate plant, there are cases where the element group to be registered remains in the target drawing. In this case, the control unit 15 may cause the display unit 11 to display a screen as shown in FIG. 14 or the like, which will be described later, based on the user's operation. Furthermore, as described above in the first embodiment, the user may select an element group to be registered by selecting an area in the drawing with the touch operation 3 .

The control unit 15 may cause the display unit 11 to display information on the processing result of this application as shown in FIG. In FIG. 9, the number of registered element groups (the number of registered groups) finally registered is 350 in the target drawing, including the registration of additional element groups specified by the user. Of these 350, 330 of "number of registered groups (automatic)" are automatically registered by reusing the data of the existing element group selected in the existing drawing. "Existing element group" is a registered element group registered for an existing plant. Of these 350, 20 of the "number of registered groups (manual)" are not included in the element group list indicating the registered element groups of existing plants in the applied range, and the user selects the element group by touch operation, that is, manually. is a group of registered elements. By displaying information of such processing results on the display unit 11, it is possible to visualize work efficiency (effect) when the information processing apparatus 10 is used. Furthermore, the control unit 15 divides the number of registered element groups automatically registered by reusing the data of the existing element groups by the number of registered element groups finally registered in the target drawing, thereby A rate may be calculated. In this case, the control unit 15 may cause the display unit 11 to display the coverage ratio.

FIG. 10 is a flow chart showing an example of a procedure for generating a new element group list of the information processing apparatus 10 shown in FIG. The control unit 15 executes processing as shown in FIG. The information processing method including the procedure as shown in FIG. 10 may be realized as a program to be executed by the processor of the information processing device 10 . This program may be stored in a non-transitory computer-readable medium. The processing of the information processing device 10 essentially reuses the data of the existing element group extracted from the existing drawing that can be applied to the target drawing to be worked on, and searches from the target drawing. It is to execute. Therefore, the process of FIG. 10 may be executed as a series of processes, or another procedure may be added and the process shown in FIG. 10 may be executed.

In the processing of step S<b>20 , the control unit 15 acquires the basic information of the plant stored in the storage unit 14 . In the processing of step S20, the control unit 15 selects existing plants having basic information matching a predetermined number or more of items with the basic information of the target plant from among the plurality of existing plants as candidate plants.

In the process of step S<b>21 , the control unit 15 acquires an existing element group list of multiple candidate plants stored in the storage unit 14 . In the processing of step S21, the control unit 15 executes provisional application processing for detecting hit element groups from existing element group lists of a plurality of candidate plants.

The control unit 15 selects the candidate plant with the largest number of hits from among the plurality of candidate plants as the applicable plant (step S22).

The control unit 15 executes the main application process of searching for an element group that matches the hit element group of the applied plant from the target drawing (step S23). This process is executed by the same procedure as the search process of the first embodiment.

The control unit 15 determines whether or not there is an existing plant having a hit element group that does not overlap with the hit element group of the applicable plant, among the existing plants other than the existing plant selected as the applicable plant in step S22. (Step S24). That is, the control unit 15 determines whether or not there is a difference group (difference element group) in the element group list (group list) of other existing plants.

The control unit 15 determines that there is no other existing plant that has a hit element group that does not overlap with the hit element group of the applicable plant, that is, if there is a difference element group in the element group list of the other existing plant. If it is determined that it does not exist (step S24: NO), the process of generating the element group list is terminated.

The control unit 15 detects that among other existing plants, there is an existing plant that has a hit element group that does not overlap with the hit element group of the applicable plant, that is, if there is a difference element group in the element group list of the other existing plant If it is determined to exist (step S24: YES), the existing plant is selected as a new application plant (auxiliary application plant) (step S25). The control unit 15 re-executes the main application process using the hit element group of the new applied plant (auxiliary applied plant) (step S23). In the process of step S23 again, the control unit 15 uses a hit element group that does not overlap with the hit element group of the previous applied plant among the hit element groups of the new applied plant.

The control unit 15 may execute the processes of steps S20 to S25 in the background.

As described above, in the information processing apparatus 10 according to the second embodiment, the control unit 15 selects the elements existing in the target drawing for which a new element group list is to be generated from among the registered element groups of the existing element group list. Find hit elements that match the group. Furthermore, the control unit 15 generates a new element group list based on the hit element group. Such a configuration saves the user the trouble of manually selecting the element group to be edited or corrected from the target drawing as the registered element group. Therefore, according to the second embodiment, an information processing apparatus 10 and an information processing method with improved convenience are provided.

(Third embodiment)
In the third embodiment, a configuration for creating a master library of element groups (groups) will be described. As in the above configuration, the master library does not select a group of elements that can be applied to the target drawing (drawings corresponding to it, objects such as plants that are the basis of it), but extracts from the drawings of past objects It is generalized so that it can be applied to any subsequent drawing by collecting the elements that have been created as a collection of data without duplication. The master library may be stored in the storage unit 14 or the like and updated as needed. As will be described later, the master library can be used to create a new element group list and the like for the target plant.

The control unit 15 uses the existing element group list generated in the existing plant to generate a master library. Registered element groups in the existing element group list are element groups that have been used in existing drawings. A highly versatile master library can be generated by using an existing element group list.

Specifically, the control unit 15 acquires an existing element group list from the storage unit 14 . The control unit 15 may receive and acquire an existing element group list through the communication unit 13 from an external device via the network 2 . After acquiring a plurality of existing element group lists, the control unit 15 extracts registered element groups from the registered element groups of the plurality of existing element group lists so as not to overlap each other. The control unit 15 generates a master library composed of the extracted registration element group.

<Processing for storing registered group data>
When extracting a registered element group from an existing element group list of an existing plant, the control unit 15 may acquire registered element group data (registered group data) from drawing data of the existing plant. The control unit 15 may acquire the data of the registered element group from the data of the drawing of the existing plant, and may also acquire from the storage unit 14 information about the notation rules adopted for the drawing of the existing plant. The control unit 15 may store the data of the registered element group for each notation rule in the master library. The data of the registered element group stored in the master library can be used as the data of the element group of the target drawing. By storing the data of the registered element group for each notation rule in the master library, the master library becomes more versatile.

For example, as shown in FIG. 11, the control unit 15 stores data of registered element groups 70, 71, and 72 for each different notation rule α and notation rule β.

In the notation rule α, the symbol for the element A is represented by the letter "A" and a circular figure, although this is not a symbol used in actual drawings but a conceptual illustration. In the notation rule α, the symbol for the element B is represented by the letter "B" and a circular figure. In the notation rule α, the symbol for the element C is represented by the letter "C" and a circular figure.

In the notation rule β, the symbol of the element A is represented by the letter "A" and the circular figure, as in the notation rule α. In the notation rule β, the symbol of the element B is represented by the letter “B” and a rectangular figure, unlike the notation rule α. In the notation rule β, the symbol of the element C is represented by the letter “C” and the circular figure, as in the notation rule α. That is, in this example, only the element B of the three elements has different symbols between the two notation rules α and β.

Each of the registration element groups (registration groups) 70-72 is composed of at least one of the elements A-C. Each of the data of the registered element groups 70-72 is represented by symbolic data of each of the elements A to C constituting each of the registered element groups 70-72.

<Registration group data generation processing>
Here, in a master library consisting of a set of element groups actually used in existing drawings, as shown in FIG. Data does not exist. The reason is that the data of the registered element group 71 of the notation rule β and the data of the registered element group 72 of the notation rule α do not exist in the drawing data of the existing plant. On the other hand, in past drawings, there is a track record of using all of the registered element groups 71, 72, and 73, and there is also a track record of using the two types of notation, rule α and rule β, so the column is left blank. There is a possibility that the data of the registered element group will be used in future drawings for the element group of the part that is included.

Therefore, the control unit 15 generates data of a registered element group with a notation that does not exist in the master library. As an example, if the data of the registered element group of the predetermined notation rule does not exist in the master library, the control unit 15 uses the existing data of the registered element group and the predetermined notation rule to create the registered element group of the predetermined notation rule. data. The control unit 15 adds the generated registered element group data to the master library. Such a configuration makes the master library more versatile.

For example, as shown in FIG. 12, the control unit 15 generates data of the registered element group 71 of the notation rule β and stores it in the master library. The control unit 15 generates the data of the registered element group 71 of the notation rule β based on the notation rule β and the data of the registered element group 71 of the notation rule α as existing data. The control unit 15 generates data of the registered element group 71 of the notation rule β by converting the symbol (circle) of the element B represented by the notation rule α into the symbol (rectangle) used by the notation rule β.

For example, as shown in FIG. 12, the control unit 15 generates data of a registered element group 72 of the notation rule α and stores the data in the master library. The control unit 15 generates the data of the registered element group 72 of the notation rule α based on the notation rule α and the data of the registered element group 72 of the notation rule β which is existing data. The control unit 15 converts the symbol (rectangle) of the element B represented by the notation rule β into the symbol (circle) used by the notation rule α, thereby generating data of the registered element group 72 of the notation rule α. Here, the symbol difference (element B) for each notation rule is exemplified by whether the outer shape of the symbol is circular or rectangular, but this is only an example, and the symbol difference is not limited to this. For example, the information processing apparatus 10 can handle various notational differences, such as different geometric figures combined with the same circle, different characters combined, and different colors used.

The control unit 15 may generate data of a registered element group whose usage frequency is equal to or higher than a threshold among the data of the registered element group that does not exist in the master library. With such a configuration, it is possible to suppress an increase in the amount of data in the master library while adding data of a registered element group with high versatility to the master library. The frequency of use is the degree to which the registered element group was used in existing plant drawings. Alternatively, comprehensiveness may be enhanced by specializing in frequently used formats (rules). The control unit 15 may appropriately calculate the frequency of use of the data of the registered element group by appropriately analyzing the drawings of the existing plant. The threshold may be appropriately set according to the amount of data in the master library.

<Update process>
After generating the master library, the control unit 15 may execute update processing of the master library. By updating the master library, the master library becomes more versatile.

As an example of update processing, the control unit 15 updates the master library when an element group selected by a user operation in the drawing is newly registered as a registered element group after the master library is generated. If the registered element group registered by the user's operation does not overlap with the registered element group of the master library, the control unit 15 updates the master library by adding the registered element group registered by the user's operation to the master library. By updating the master library with the registered element group registered by the user's operation, the updated master library becomes more versatile.

As another example of update processing, when the control unit 15 receives and acquires a new element group list from an external device via the network 2 through the communication unit 13 after generating the master library, the control unit 15 updates the master library. The control unit 15 extracts a registered element group that does not overlap with the registered element group of the master library from the registered element group of the new element group list, and adds the extracted registered element group to the master library, thereby updating the master library. do. By updating the master library, the updated master library becomes more versatile.

The control unit 15 may appropriately execute the storage process and the generation process of the data of the registered element group in the update process of the master library.

<Processing for generating a new element group list>
The control unit 15 generates an element group list of the target plant using the master library. A method of generating an element group list for a target plant using the master library will be briefly described below. The process of creating a new element group list using the master library may be performed according to the user's instruction, but when the system acquires the data such as the target drawing and the existing element group, the information processing The device 10 may do so automatically. For example, the information processing apparatus 10 automatically executes processing during a time period (nighttime, etc.) when the user is not working, and when the user tries to work on the target drawing, the necessary element group data is used. You can make it possible. As a result, it becomes easy for the user to appropriately reuse the past data and perform processing such as changing the drawing without the user being aware of it.

First, the control unit 15 detects a hit element group from the registered element group of the master library in the same manner as the provisional application process. The control unit 15 generates the element group list of the target plant by setting the detected hit element group as the registered element group of the element group list of the target plant. Such a configuration saves the user the trouble of manually selecting the element group to be edited or corrected from the target drawing as the registered element group.

The control unit 15 may acquire the data of the registered element group detected as the hit element group from the data of the registered element group stored in the master library. In this case, the control unit 15 may use the acquired data as the data of the registered element group of the target drawing. The control unit 15 retrieves the data of the registered element group detected as the hit element group among the data of the registered element group of the master library, and the data of the registered element group associated with the notation rule adopted for the target drawing. You may obtain it.

Next, the control unit 15 executes the processing of this application using the detected hit element group. With such a configuration, matching element groups that match the hit element group are automatically searched in the target drawing.

FIG. 13 is a flow chart showing an example of the procedure of the master library generation process of the information processing apparatus 10 shown in FIG. The control unit 15 starts processing as shown in FIG. The information processing method including the procedure as shown in FIG. 13 may be implemented as a program to be executed by the processor of the information processing device 10 . This program may be stored in a non-transitory computer-readable medium.

The control unit 15 acquires a plurality of existing element group lists (group lists) from the storage unit 14 (step S30).

The control unit 15 extracts registered element groups (registered groups) from the registered element groups of the plurality of existing element group lists acquired in the process of step S30 so as not to overlap each other (step S31).

The control unit 15 generates a master library composed of the registered element group extracted in the process of step S31 (step S32).

The control unit 15 stores the data of the registered element group in the master library (step S33).

If the data of the registered element group of the predetermined notation rule does not exist in the master library, the control unit 15 sets the predetermined notation rule and the notation method (element group data, line, etc., usage of symbols, etc.) used in the notation rule. rule), data of a group of registered elements of a predetermined notation rule is generated (step S34). The control unit 15 adds the generated registered element group data to the master library.

The control unit 15 updates the master library (step S35). For example, the control unit 15 receives and acquires a new element group list from an external device via the network 2 by the communication unit 13 when an element group selected by user operation in the drawing is newly registered as a registered element group. If so, update the master library. If it is a registered element group that already exists in the master library, no update is required.

The control unit 15 detects a hit element group, which is an element group that matches the element group existing in the target drawing, from the registered element group of the master library (step S36). The control unit 15 executes the application process using the detected hit element group (step S37).

As described above, the control unit 15 may execute the processes of steps S30 to S35 in the background.

As described above, in the information processing apparatus 10 according to the third embodiment, the control unit 15 extracts registered element groups from registered element groups in a plurality of existing element group lists so as not to overlap, and uses the extracted registered element groups Generate a composed master library. The master library can be used to generate new element group lists for the target drawing. Such a configuration saves the user the trouble of manually selecting the element group to be edited or corrected from the target drawing as the registered element group. Therefore, according to the third embodiment, an information processing apparatus 10 and an information processing method with improved convenience are provided.

(Fourth embodiment)
In the fourth embodiment, display processing for displaying the target drawing on the display unit 11 in the operation of selecting and registering an element group from the target drawing will be described. In this embodiment, the control unit 15 searches for an existing registered element group in the target drawing, and if it exists, displays the corresponding part in the target drawing in a manner different from the others. If there is an element group to be newly registered at a location other than the existing registered element group searched and displayed in a different manner in the target drawing, the control unit 15 registers it as a new registered element group according to the user's designation. . If the description rule (format) of the existing registered element group and the target drawing are different, the control unit 15 matches the description rule of the existing registered element group with the description rule of the target drawing, and then searches in the target drawing. I do. By these processes, a portion matching an existing registered element group and an element group to be newly registered are displayed in a manner different from others in the target drawing. Therefore, the user can easily recognize the locations in the target drawing that match the existing registered element group and the element group that should be newly registered without being conscious of the difference in the description rules between the existing drawing and the target drawing. , the labor for selecting the registration element group is reduced.

For example, the user may cause the display unit 11 to display the drawing of the plant as the target drawing in order to correct or change the drawing of the plant that is currently being designed, or to improve or change the plant that was designed in the past. be. In this case, the control unit 15 may use, as the existing registered element group, a registered element group registered by the process according to the first embodiment in a drawing used when designing another plant in the past. When the input unit 12 receives a user operation for designating a target drawing to be displayed on the display unit 11, the control unit 15 executes the search process using the existing registered element group. In other words, the control unit 15 uses the existing registered element group as a search element group, and searches the target drawing for a matching element group that matches the search element group. Here, if the description rule (format) of the existing registered element group and the target drawing are different, the control unit 15 adjusts the description rule of the existing registered element group to the description rule of the target drawing, and then Do a search on .

If there is a matching element group retrieved by the search process in the target drawing, the control unit 15 executes processing for changing the display mode of the matching element group in the target drawing to a display mode different from that of other parts of the target drawing. With such a configuration, the user can easily grasp the element group to be registered. Also, the user can easily grasp how many element groups to be registered exist.

As the process of changing the display mode of the image of the target drawing, the control unit 15 executes the process of lowering the visibility of the image of the matching element group matching the existing registered element group to make it less conspicuous than the other parts. may The control unit 15 executes, for example, a process of lowering the brightness or saturation of the image as the process of lowering the visibility of the image of the matching element group. With such a configuration, the user can more easily grasp the matching element group to be registered.

For example, the control unit 15 causes the display area 11A of the display unit 11 to display an image of the target drawing as shown in FIG. In FIG. 14, the images of the target drawing include images 80, 81 and 82. FIG. Images 80-82 are images showing matching elements that match existing registration elements. The images 80 to 82 are processed by the control unit 15 to reduce visibility. Elements located in region 83 are images of unregistered elements. The user selects the element group located in the area 83 by the touch operation 3 in order to add the element group located in the area 83 to the element group list as the registered element group.

The control unit 15 controls the visibility of only the portions other than the symbol portions without lowering the visibility of the symbol portions indicating each element included in the element group in the image indicating the matching element group that matches the existing registered element group. can be lowered. Through such processing, the user can grasp the configuration of each element in the existing registered element group.

<Example of conversion processing>
The control unit 15 may use data of existing registered element groups to search for element groups to be registered in the target drawing. At that time, if the existing registered element group is represented by the first notation rule and the target drawing is represented by the second notation rule, the control unit 15 converts the data of the existing registered element group to the second notation rule. Used for the subject drawing above. The conversion of the notation rule is as follows, for example.

For example, when the existing registered element group is a hit element group detected by the process according to the second embodiment, the data of the existing registered element group is the hit element group acquired from the data of the drawing of the applied plant. data. Also, the first notation rule is a notation rule applied to drawings of applicable plants. When the data of the hit element group is converted according to the notation rule adopted for the drawing of the applicable plant, the control unit 15 may use the converted data of the hit element group as the data of the registered element group. .

For example, if the existing registered element group is a hit element group detected from the master library by the process according to the third embodiment, the data of the registered element group is obtained from the master library and detected as the hit element group. This is the data of the registration element group. The first notation rule is a notation rule associated with the data of the registered element group in the master library.

For example, when a user wants to display a drawing of a plant designed in the past as a target drawing on the display unit 11 in order to improve and change the plant, the data of the existing registered element group is used when the plant was designed in the past. It is obtained from the data of the drawing used for Also, the first notation rule is a notation rule adopted for drawings used when the plant was designed in the past.

For example, when the user reuses information extracted in a drawing different from the target drawing, the data of the existing registered element group is obtained from the other drawing. Also, the first notation rule is a notation rule adopted for the other drawing.

For example, element groups 90 and 91 exist in the target drawing as shown in FIG. Element group 90 consists of a valve, element A and element B. FIG. Element group 91 is composed of two valves and element A. In the configuration shown in FIG. 15, the second notation rule adopted for the target drawing is the notation rule β. The first notation rule is the above notation rule α. Note that the symbol for the valve is the same in the notation rule α and the notation rule β. The data represented by the notation rule β of the element group 90 differs from the data represented by the notation rule α of the element group 90 because the element group 90 includes the element B. Further, the data of the element group 91 represented by the notation rule β becomes the same as the data of the element group 91 represented by the notation rule α because the element group 91 is composed of the valve and the element A.

Based on the first notation rule and the second notation rule, the control unit 15 determines whether the data of the existing registered element group and the data of the target drawing are different. For example, when the first notation rule of the data of the existing registered element group is different from the second notation rule of the target drawing, the control unit 15 determines that the data of the existing registered element group and the data of the element group of the target drawing are different. I judge.

When determining that the first notation rule and the second notation rule are different, the control unit 15 converts the data of the existing registered element group to the second notation rule. The control unit 15 uses the converted registered element group data as a search element group or the like in the target drawing. With such a configuration, the data of the element group according to the second notation rule is automatically displayed in the target drawing. Convenience is improved by automatically displaying the data of the element group according to the second notation rule.

On the other hand, if the control unit 15 determines that the first notation rule and the second notation rule are the same, it uses the data of the existing registered element group as it is as the search element group or the like in the target drawing.

For example, in the configuration shown in FIG. 15, the control unit 15 uses, as the data of the element group 90 in the target drawing, the data represented by the notation rule α of the element group 90 converted according to the notation rule β. With such a configuration, in the image 92 of the element group 90, the element B is represented by the letter "B" and the rectangular figure. In addition, the control unit 15 retrieves the registered element group in the target drawing using the data of the existing registered element group, that is, the data of the element group represented by the notation rule α of the element group 91 as the data of the element group 91 in the target drawing. used for

When the data of the existing registered element group after conversion is used in the target drawing, the control unit 15 makes the display mode of the image showing the existing registered element group out of the image of the target drawing different from that of other parts. Execute the process of changing the mode. As the process of changing the display mode of the image of the target drawing, the control unit 15 may execute the process of lowering the visibility of the image of the existing registered element group as described above, or change the color of the image to other parts. may be displayed in a different color. With such a configuration, the user can easily grasp the element group into which the data has been converted. For example, the control unit 15 displays an image 92 showing an element group 90 as shown in FIG. 15 in a display mode separate from other parts of the target drawing.

When the data of the existing registered element group is used as it is as the data of the target drawing, the control unit 15 changes the display mode of the image showing the existing registered element group out of the image of the target drawing to the other part of the image of the target drawing. Change to a different display mode. With such a configuration, the user can easily grasp the element group whose data is not converted. The control unit 15 may execute the process of lowering the visibility of the image of the existing registered element group as described above, or the process of displaying the image of the existing element group in a color different from that of other parts. may be executed. For example, the control unit 15 displays an image 93 showing an element group 91 as shown in FIG. 15 in a display mode different from other parts of the target drawing.

When the existing element group data after conversion is used, the control unit 15 may cause the display unit 11 to display the data before conversion, that is, the existing element group data. With such a configuration, the user can grasp the data before conversion. For example, as shown in FIG. 15, the control unit 15 causes the display area 11B to display the data of the element group 90 represented by the notation rule α together with the identification information of the element group No. 003. The identification information for the element group No. 003 is the identification information for the element group 90 . Further, the control unit 15 may cause the display unit 11 to display the data before conversion, that is, the data of the second element group, and the data of the second element group after conversion according to the first notation rule. With such a configuration, the user can grasp the data after conversion and the data before conversion. For example, as shown in FIG. 15, the control unit 15 causes the display area 11B to display the data of the element group 90 represented by the notation rule α and the data of the element group 90 represented by the notation rule β.

FIG. 16 is a flow chart showing an example of a data conversion process procedure of the information processing apparatus 10 shown in FIG. For example, when the control unit 15 shifts the mode of the information processing apparatus 10 to a mode in which an element group in the drawing can be selected by a user operation, the processing shown in FIG. 16 is started. The information processing method including the procedure as shown in FIG. 16 may be realized as a program to be executed by the processor of the information processing device 10 . This program may be stored in a non-transitory computer-readable medium.

The control unit 15 determines whether or not the description rule (first notation rule) of the existing registered element group (registration group) and the description rule (second notation rule) of the target drawing are different (step S40). This existing registered element group may be, for example, each element group of a master library. If the control unit 15 determines that the description rules are different (step S40: YES), the process proceeds to step S41. On the other hand, when the control unit 15 determines that the writing rules are the same (step S40: NO), the process proceeds to step S42.

In the process of step S41, the control unit 15 performs a process of matching the description rule (first notation rule) of the existing registered element group (registration group) with the description rule (second notation rule) of the target drawing. For example, if the description rule (first notation rule) of the existing registered element group is the notation rule α and the description rule (second notation rule) of the target drawing is the notation rule β, the control unit 15 controls the existing registered element Convert the notation rule of the group from the notation rule α to the notation rule β.

In the process of step S42, the control unit 15 searches the target drawing using the existing registered element group (registered group) as the search element group, and determines whether or not the existing registered element group exists in the target drawing. If the control unit 15 determines that an existing registered element group exists in the target drawing (step S42: YES), the process proceeds to step 43; otherwise (step S42: NO), the process ends. Note that, when the control unit 15 searches for a registered element group within the target drawing, the control unit 15 stores the position information of the registered element group in the storage unit 14 and registers the information of each registered element group within the target drawing. can be reused.

In the processing of step S43, the control unit 15 causes the display unit 11 to display the portion matching the existing registered element group in the target drawing in a manner different from the others. For example, the control unit 15 makes the portion that matches the existing registered element group less conspicuous than other portions and displays it.

In the process of step S44, the control unit 15 determines whether or not an unregistered element group (group) to be newly registered exists in the target drawing. If it exists (step S44: YES), the control unit 15 proceeds to step 45, otherwise (step S44: NO) ends the process.

In the process of step S45, the control unit 15 performs a process of registering an unregistered element group. Specifically, the control unit 15 may receive a selection of the corresponding part from the user via the input unit 12 and register the selected element group. Then, the control unit ends the processing.

As described above, in the information processing apparatus 10 according to the fourth embodiment, the control unit 15 determines whether an existing registered element group exists in the target drawing to be displayed on the display unit 11 . When determining that the registered element group exists in the target drawing, the control unit 15 makes the display mode of the image of the registered element group out of the image of the target drawing less conspicuous than other parts of the image of the target drawing. Execute processing to change to a different display mode. With such a configuration, the user can more easily grasp the element group to be registered. Therefore, according to the fourth embodiment, an information processing apparatus 10 and an information processing method with improved convenience are provided.

Furthermore, according to the fourth embodiment, when the existing registered element group is represented by the first notation rule and the target drawing is represented by the second notation rule, the control unit 15 converts the data of the existing registered element group to After converting to the second notation rule, it is used for the target drawing. Therefore, even if the notation rule of the existing registered element group is different from that of the target drawing, the control unit 15 converts it to the notation rule of the target drawing and then selects the element group that conforms to the existing registered element group. It can be automatically registered by searching from drawings. Therefore, it is possible to reduce the trouble of the user manually selecting the element group to be edited or corrected from the target drawing as the registered element group.
