Description

Technical Field

[0001] The present invention relates to a piping management system and a piping management method.

Background Art

[0002] A plant is composed of equipment such as piping and pumps, and various facilities, and these facilities are listed in an equipment list. The equipment list may be divided into one or more piping lists and one or more equipment lists, etc.

[0003] Moreover, in many plants, equipment inspections, maintenance, equipment modifications (such as additions and changes, etc.) are carried out regularly / irregularly. And the process and results are managed as multiple types of drawing data (P&ID diagrams, etc.) and numerical data (pipe wall thickness inspections, etc.).

[0004] Also, in the process of plant construction and equipment modification, two-dimensional drawings of equipment, images, three-dimensional models representing three-dimensional shapes, etc. are generated. Furthermore, in recent years, data that can show the on-site situation, such as point cloud data measured by a laser measuring machine, etc., and photos (panorama photos) associated with the measurement points, etc., have also come to be collected.

[0005] Among these, some data (for example, units (equipment, equipment groups or systems) in the equipment list) may be managed by an individual identification information system, while other data may not be managed by this identification information system. Furthermore, some other data (for example, point cloud data and two-dimensional images) may be managed by the directory structure of the storage location, file names, and other meta-information without being given management identification information. Therefore, although the plant manager has various data related to the plant, the actual situation is that these are managed separately and data utilization cannot be carried out well.

[0006] Patent Document 1 discloses a plant management system that enables reliable database management with minimal workload. Specifically, the plant management system comprises an image display unit 32, an image database 4a that stores multiple image data, a point cloud database 4b that stores point cloud data defining a three-dimensional structure, and an attribute information database 4c that stores attribute information. The multiple image data and point cloud data are associated via a common three-dimensional coordinate system, and when attribute information corresponding to a selected range is input, the attribute information is processed in association with the point cloud data.

[0007] Patent Document 2 discloses a structural information provision system that facilitates the acquisition of data necessary for the analysis of road structures and effectively reduces the workload in road management operations. Specifically, the structural information provision system is disclosed to consist of a measurement vehicle 10 that measures road structures and the surrounding terrain and shape along with their positional information while driving on the road and acquires the measurement results as point cloud data; a management server 20 that acquires and manages the point cloud data showing the shape of the road structures from the measurement vehicle 10 and manages structural data related to the structure and properties of the road structures; and a user terminal 30 operated by a road management company that acquires the point cloud data and structural data from the management server 20 via a network.

[0023] Further details will be provided below with reference to the attached drawings. The drawings show preferred embodiments. However, many different forms are possible and the embodiments are not limited to those described herein.

[0024] For example, this embodiment describes the configuration and operation of a piping management system, but similar effects can be achieved by the method, device, computer program, etc. The program in this embodiment may be provided as a non-transient recording medium readable by a computer, or it may be provided so that it can be downloaded from an external server, or the program may be launched on an external computer to realize its functions on a client terminal (so-called cloud computing).

[0025] Furthermore, in this embodiment, "part" may include, for example, hardware resources implemented by a circuit in a broad sense, and the information processing of software that can be specifically realized by these hardware resources. In this embodiment, "information" is represented, for example, by the physical value of a signal value representing voltage and current, or by the high or low value of a signal value as a set of binary bits consisting of 0s or 1s, and communication and calculations can be performed on a circuit in a broad sense.

[0026] <System Configuration> Figure 1 is a block diagram showing the configuration of a system according to one embodiment. As shown in Figure 1, the piping management system 0 comprises an information processing device 1, a database server 2, and an external database 3. The information processing device 1, the database server 2, and the external database 3 are configured to communicate with each other via a network NW.

[0027] In this embodiment, the network NW is a network bus. The network NW may include, for example, an IP (Internet Protocol) network. There are no restrictions on the type of communication protocol in the network NW, nor on the type or size of the network.

[0028] The information processing device 1 can utilize a general-purpose personal computer or the like. Alternatively, a server-oriented computer may be used, and the information processing described later may be achieved by sending and receiving information via a client terminal. Furthermore, it is possible to configure the information processing device 1 using multiple computers. Additionally, one or more other terminal devices may be connected to the network NW to enable the display of information stored in the database server 2.

[0029] <Hardware Configuration> Figure 2 is a hardware configuration diagram of the information processing device 1, the database server 2, and the external database 3. Figure 2(a) is a diagram showing an example of the hardware configuration of the terminal device 90 (information processing device 1). The terminal device 90 comprises a control unit 91, a storage unit 92, a communication unit 93, an input unit 94, and an output unit 95 as its hardware configuration.

[0030] The control unit 91 of the terminal device 90 includes one or more processors such as a CPU, and controls the overall operation of the information processing device 1 by executing the piping management program 11 according to the present invention, an OS, browser software, and other applications. The storage unit 92 of the terminal device 90 is an HDD, ROM, RAM, etc., and stores the above-mentioned piping management program 11 and data used by the control unit 91 when executing processing based on the program. The control unit 91 executes processing based on the piping management program stored in the storage unit 92, thereby realizing the functional configuration described later. The communication unit 93 of the terminal device 90 performs communication control with the network NW and provides inputs necessary to operate the information processing device 1 and outputs related to the operation results. The input unit 94 of the terminal device 90 is a touch panel, mouse, keyboard, etc., which inputs operation requests from the user to the control unit 91. The output unit 95 of the terminal device 90 is a display, etc., which displays the results of processing by the control unit 91.

[0031] Figure 2(b) shows an example of the hardware configuration of the server device 10 (database server 2 and external database 3). The server device 10 comprises a control unit 101, a storage unit 102, and a communication unit 103 as its hardware configuration.

[0032] The control unit 101 includes one or more processors such as a CPU and controls the entire operation process of the server device 10 by executing a database management program and other applications. The storage unit 102 is an HDD, ROM, RAM, etc., and stores the piping management program according to the present invention and various data used by the piping management system 0. The communication unit 103 performs communication control with the network NW and provides inputs necessary to operate the information processing device 1 and outputs related to the operation results.

[0033] The storage unit 102 of database server 2 includes a unique ID table 21, a unique ID linking table 22, equipment management list DB 23, plan diagram DB 24, partition DB 25, point cloud DB 26, 3D model DB 27, P&ID diagram DB 28, spool diagram DB 29, and panoramic image DB 30, as well as equipment-related diagrams. The storage unit 102 of external database 3 includes a maintenance information DB 31 that stores maintenance information for individual equipment, and an operation status information DB 32 that stores operating status information for individual equipment. These DBs and equipment-related diagrams may be stored on different storage media.

[0034] <Functions of the information processing device> Figure 3 is a functional block diagram of the information processing device 1. The information processing device 1 comprises a registration unit 12, a partitioning unit 13, a linking unit 14, a display processing unit 15, and a generation unit 16 as its functional configuration. This represents the concrete realization of information processing by software (stored in the storage unit 92) by hardware (control unit 91, etc.).

[0035] The registration unit 12 receives equipment-related diagrams and registers the equipment-related diagram information with the database server 2 (storage unit), and also stores the equipment-related diagrams. The equipment-related diagrams include equipment management lists with equipment or systems as elements, point cloud data associated with measurement information, pipeline diagrams that depict the connection status of multiple pieces of equipment such as P&ID diagrams and spool diagrams, 3D models that include one or more pieces of equipment or systems or models as elements, panoramic images taken inside the equipment, and diagrams, tables, etc. related to the plant, such as inspection results and document data such as manuals.

[0036] In this embodiment, the registration unit 12 registers equipment management information, which is equipment-related diagram information, in the equipment management list DB23 based on the equipment management list. It also stores equipment-related diagram information related to plan diagrams in the plan diagram DB24, equipment-related diagram information related to point cloud data in the point cloud DB26, equipment-related diagram information related to P&ID diagrams in the P&ID diagram DB28, equipment-related diagram information related to spool diagrams in the spool diagram DB29, and equipment-related diagram information related to panoramic images in the panoramic image DB30. Furthermore, based on the 3D model file, it registers multiple pieces of equipment-related diagram information related to multiple 3D models contained in the file in the 3D model DB27.

[0037] When registering equipment-related diagram information, the registration unit 12 generates a unique ID (registration identification information), and associates the unique ID with the equipment-related diagram information by associating the individual elements included in the equipment-related diagram or information related to the equipment-related diagram with the unique ID.

[0038] A unique ID (registration identification information) is unique to each individual element or each equipment-related diagram stored in the database server 2. While equipment management lists (equipment-related diagrams) may contain identification information such as equipment numbers to identify individual equipment (elements) within the file, the registration unit 12 generates a unique ID (registration identification information) that is distinct from this identification information and unique within the database server 2. The registration unit 12 also stores equipment-related diagram information in association with categories. Categories are information assigned when a unique ID is generated, and for example, they indicate which equipment-related diagram information (in this embodiment, equipment management list, 3D model, plan diagram, point cloud data, P&ID diagram, spool diagram, panoramic image, etc.) the unique ID corresponds to. Categories streamline searches and other operations when managing data collectively using unique IDs.

[0039] In this embodiment, when an equipment management list (equipment-related diagram) is registered, equipment management information is registered with a unique ID associated with each record, which is an individual element included in the equipment management list. Furthermore, based on a 3D model file containing multiple 3D models, equipment management information is registered with a unique ID associated with each 3D model, which is an individual element included in the 3D model file. The unit of a 3D model is arbitrary and may be an individual part of a 3D model, a model corresponding to one piece of equipment formed by combining parts, or a group that is a combination of multiple models. When assigning a common unique ID to a group containing multiple models, a group number may be assigned. For plan diagrams, point cloud data, P&ID diagrams, spool diagrams, and panoramic images, equipment management information with a unique ID associated with each file is registered. The files entered when registering equipment-related diagram information are stored in the storage unit of the database server 2, etc., and the file name, path, etc. are stored associated with the equipment-related diagram information.

[0040] The partitioning unit 13 sets up partitions for the plan diagram. In this embodiment, the registration unit 12 accepts the registration of a plan diagram showing a floor plan of a facility that has been created in advance, and the partitioning unit 13 defines multiple partitions for this floor plan. The partitioning unit 13 also generates a plan diagram of the facility based on point cloud data. Hereafter, the floor plan of a facility that has been created in advance will be simply called a plan diagram, and the plan diagram generated based on point cloud data will be called a point cloud plan diagram.

[0041] The linking unit 14 is registered with the database server 2 (storage unit), associates the equipment-related diagram information specified via the interface, and registers these combinations with the database server 2, thereby defining the correspondence between independently generated equipment-related diagrams.

[0042] The display processing unit 15 processes and displays various screens on which the user performs operation input. At this time, the display processing unit 15 processes and displays related equipment-related diagrams and equipment-related diagrams according to the combination of equipment-related diagram information in the database server 2. Equipment-related diagrams are referenced by file names, paths, etc., included in the equipment-related diagram information and are processed and displayed by the display processing unit 15. The display processing unit 15 is configured to search and process equipment-related diagrams that are indirectly associated with the specified equipment-related diagram information, in addition to equipment-related diagram information directly associated with the linking unit 14, by searching the combinations, and to be able to display them.

[0043] The generation unit 16 generates a plan view image and a 3D model for generating a point cloud plan drawing based on the point cloud data. Hereafter, the 3D model of the equipment created in advance will be simply referred to as the plan drawing, and the 3D model generated based on the point cloud data will be referred to as the 3D model.

[0044] <Piping management method> Referring to Figures 4-8, we will explain the piping management method using the piping management system 0 and the processing content of each functional component. Figure 4 is a flowchart showing the overall procedure from registration to mapping of equipment-related diagram information in the piping management system 0.

[0045] First, in step S41, the registration unit 12 of the information processing device 1 accepts the registration of the equipment-related diagram file to the database server 2 (storage unit), generates a unique ID, registers the equipment-related diagram information, and stores the equipment-related diagram file in the database server 2 (storage unit).

[0046] <Registration of equipment-related diagrams and information to the database server> Figure 5 is a data structure diagram of equipment-related diagram information stored in the storage unit 102 of the database server 2. The unique ID table 21 contains unique ID information, including a unique ID, the creation date and time of the unique ID, and a category. When the registration unit 12 generates a unique ID, it assigns a category based on the registered equipment-related diagram and adds the unique ID information to the unique ID table 21 along with the creation date and time. In addition, the equipment-related diagram information registered in each DB 23 to 30 is assigned a unique ID generated by the registration unit 12.

[0047] The unique ID linking table 22 stores linking information that shows combinations of equipment-related diagram information associated with the linking unit 14. The linking information is defined by pairs of unique IDs generated by the registration unit 12, and the creation date and time of the combination (linking information) are associated with it.

[0048] The Equipment Management List DB23 stores equipment management information for each record included in the equipment management list. The equipment management information is registered based on the equipment management list, which is an equipment-related diagram. The equipment management information includes a unique ID, information for referencing the equipment management list (file name in the illustrated example), at least one unique identifier within the list (equipment number), the date and time the record was created in the equipment management list, location, system, equipment details, the equipment number of the connected equipment, the equipment number of the connected equipment, etc. Equipment details may include information such as pipe size, pipe class, presence or absence of insulation, and contents in the case of piping. In the case of equipment, it may include information such as equipment type.

[0049] The plan diagram DB24 stores plan diagram information. When the registration unit 12 accepts registration of a plan diagram, it issues a unique ID for the plan diagram and stores the unique ID information in the unique ID table 21 and the plan diagram information in the plan diagram DB24. The plan diagram information is associated with the unique ID, information for the display processing unit 15 to display the registered plan diagram (file name in the illustrated example), the facility's floor number, and the date and time the plan diagram was created.

[0050] The point cloud database 26 stores point cloud data information. When the registration unit 12 receives registration of point cloud data, it issues a unique ID for the point cloud data and stores the unique ID information in the unique ID table 21 and the point cloud data information in the point cloud database 26. The point cloud data information is associated with the unique ID, information for the display processing unit 15 to display the registered point cloud data (file name in the illustrated example), a measurement number that can identify the measurement time for each point cloud data, the date and time the point cloud data was created, the measurement position coordinates which are the 3D coordinates of the measurement location, and the point cloud group. A point cloud group is a group of points that can be registered together, for example, as a unit of piping or equipment, or as a group of walls or floors, and is used to display or hide and color-code each group. It is also used to add comments to point cloud groups.

[0051] The 3D model DB27 stores 3D model information. When the registration unit 12 receives registration of a 3D model file, it issues a unique ID for each element (for each 3D model) contained in the 3D model file, and stores the unique ID information in the unique ID table 21 and the 3D model information in the 3D model DB27. The 3D model information is associated with the unique ID, information for the display processing unit 15 to display the registered 3D model (file name in the illustrated example), data number in the registered 3D model file, creation date and time of the 3D model file, file standard of the 3D model file, type of shape data of the 3D model, coordinates where it is placed, and 3D model group. A 3D model group is used to register multiple pipes or equipment as one group and to display or hide each group, or to color-code them according to their maintenance status.

[0052] The P&ID diagram DB28 stores P&ID diagram information. When the registration unit 12 accepts registration of a P&ID diagram and when it generates a selection range file, it issues a unique ID for the P&ID diagram and stores the unique ID information in the unique ID table 21 and the P&ID diagram information in the P&ID diagram DB28. The P&ID diagram information is associated with the unique ID, information for display processing 15 to display the registered P&ID diagram (file name in the illustrated example), the diagram number of the P&ID diagram, the creation date and time of the P&ID diagram, the location indicated by the P&ID diagram, and the selection range file name. The selection range file name will be described later.

[0053] The spool diagram DB29 stores spool diagram information. When the registration unit 12 accepts registration of a spool diagram and when it generates a selection range file, it issues a unique ID for the spool diagram and stores the unique ID information in the unique ID table 21 and the spool diagram information in the spool diagram DB29. The spool diagram information is associated with the unique ID, information for the display processing unit 15 to display the registered spool diagram (file name in the illustrated example), the spool diagram number, the date and time the spool diagram was created, the location indicated by the spool diagram, and the selection range file name.

[0054] The panoramic image database 30 stores panoramic image information. When the registration unit 12 receives registration of a panoramic image, it issues a unique ID for the panoramic image and stores the unique ID information in the unique ID table 21 and the panoramic image information in the panoramic image database 30. The panoramic image information is associated with the unique ID, information for the display processing unit 15 to display the registered panoramic image (file name in the illustrated example), and the creation date and time of the panoramic image.

[0055] <Setting up the plot> Next, in step S42, the piping management system 0 creates partition information for the registered plan drawing and sets up the partitions. The display processing unit 15 displays the plan drawing stored in the memory unit and transmits the display processing result to the output unit 95. The partition unit 13 receives the dimensions and origin coordinates of the partitions, displays the partitions on the plan drawing, and registers the partition information in the partition DB 25. Here, the partition unit 13 may generate multiple partition information entries for each dimension of the partition.

[0056] As shown in Figure 5, the partition information stored in the partition DB25 is associated with the number of partitions, partition dimensions, and origin coordinates, and each partition number has a unique ID. For example, the origin coordinates refer to specific two-dimensional coordinate values ​​(x, y) on the plan diagram (image) displayed by the display processing unit 15. The plan diagram (image) is associated with the actual distance traveled at the plant facility when moving across a predetermined coordinate on the image as a scale, and the dimensions refer to the length of one side of the partition placed on the plan diagram at that time. In this embodiment, the dimensions of the x and y axes are the same, but the partition section 13 may be partitioned in the plan diagram with different dimensions for the x and y axes. In other words, the partition may be rectangular. Alternatively, the widths of the x and y axis scales in the coordinate system of the plan diagram (image) do not have to be equal.

[0057] For example, if there are 100 sections of 10 (x-axis) x 10 (y-axis) in three layers (z-axis), 300 section numbers (x, y, z) will be generated, ranging from (1, 1, 1) to (10, 10, 3), and each will be associated with a unique ID. These unique IDs are also stored in the unique ID table 21. The number of sections in each layer may be the same or different. Section information with different dimensions is associated using linking information to match the unique IDs of the section information.

[0058] Figure 6 shows an example of the screen display when creating partition information. In the example, the plan diagram PL shows the plan of the first floor of the facility, and the symbol OR in the figure indicates the origin coordinates. The plan diagram is associated with a scale (the ratio of the distance on the plan diagram to the actual distance), and partitions SExy are arranged in a matrix with the origin as the reference point, corresponding to the specified partition dimensions. In the example, 54 partitions are arranged from partition SE11(x, y, z)=(1, 1, 1) to SE69(x, y, 1)=(6, 9, 1). In this embodiment, the z coordinate indicates the floor level of the facility.

[0059] <Creating a plan diagram based on point cloud data> In step S43, the piping management system 0 creates a point cloud plan drawing using the registered point cloud data. The point cloud data file is a collection of multiple 3D coordinates, and preferably includes color information and brightness information for the points in addition to the 3D coordinates. Each point cloud data file is acquired through multiple measurement processes within the facility, but the coordinates in different point cloud data files are in a common 3D coordinate system (or can be converted to a common 3D coordinate system), and furthermore, the dimensions of this coordinate system can be converted to actual distances.

[0060] First, the generation unit 16 searches for point cloud data for generating a point cloud plan from the point cloud data files stored in the point cloud DB 26. The generation unit 16 determines the point cloud data for the plan based on the height coordinate value of the measurement position coordinates contained in the point cloud data information and the height coordinate value of the point cloud data. In this embodiment, since point cloud data measured by a laser measuring instrument is often measured from a place where there is a floor, the 3D coordinates of the point cloud data in the point cloud file that are lower in height than the z coordinate (height) of the measurement position coordinate value become the point cloud data for the plan. This allows point cloud data on the floor surface to be obtained. Then, the generation unit 16 generates a plan view image for each measurement point by projecting this point cloud data for the plan onto the xy plane. As a result, the plan view image associated with the point cloud data information is stored in the storage unit (database server 2, etc.).

[0061] The generation unit 16 performs this process for each point cloud data piece. This point cloud data and plan view image for the plan diagram are distinguished by facility level by clustering the z coordinates of the measurement position coordinates. The display processing unit 15 then displays the generated plan view image (point cloud plan diagram) with the same scale as the plan diagram, allowing it to move freely on the plan diagram. In this embodiment, the scale of the plan diagram and the plan view image can be matched by associating the coordinate values ​​of the point cloud data with the actual distance and associating the dimensions with the plan diagram. For example, the display processing unit 15 displays the plan view image transparently on the plan diagram and inputs the relative position of the plan view image with the plan diagram to align the point cloud data and the section. The linking unit 14 associates the unique ID of the point cloud data information stored in the point cloud DB 26 with the unique ID of the section and registers the linking information that associates the point cloud data information and the section in the unique ID linking table 22. This associates the point cloud data and the plan diagram (section). If a plan drawing is not available, the partitioned area 13 may generate a plan view image, save it as an image file, and use that as a plan drawing to register the partitioned area information.

[0062] <Mapping between section information and equipment-related diagrams and charts> Step S44 involves linking the partition information with any equipment-related diagram information. As an example, the procedure for associating partitions with 3D models will be described. Step S45 involves linking equipment-related diagram information with each other. These procedures can be performed in any order and at any time. Similarly, the registration of files to the database server 2 in step S41 can also be performed at any time and at any arbitrary moment.

[0063] <Mapping between parcels and 3D models> The display processing unit 15 performs display processing on the three-dimensional model and on individual elements in the three-dimensional model. Further, it performs display processing on a section (plan view and / or point cloud plan view). Then, the cooperation unit 14 uses the coordinate values of the three-dimensional model and the coordinate value range of the section to perform a process of determining whether the three-dimensional model is included in the section. The three-dimensional model has coordinate values for, for example, the central axis and diameter of the piping, along with information such as the piping type. These coordinate values are in a coordinate system corresponding to the coordinates of the section (or can be converted to the corresponding coordinate system). Thereby, the cooperation unit 14 can determine the section in which the three-dimensional model exists based on the coordinates of the three-dimensional model. The cooperation unit 14 associates the unique ID of the three-dimensional model information stored in the three-dimensional model DB 27 with the unique ID of the section, and registers them in the information cooperation information and unique ID connection table 22 that associates the three-dimensional model and the section. Thereby, the three-dimensional model, the elements in the three-dimensional model, and the plan view (section) are associated with each other.

[0064] Note that for the unique ID of the section, the unique ID of arbitrary facility-related drawing expression information other than the three-dimensional model may be associated by the cooperation unit 14.

[0065] <Procedure for Associating Facility-Related Drawing Expression Information with P&ID Diagram> Next, the process of associating a P&ID diagram, which is an image file showing a piping diagram, with facility-related drawings will be described. FIG. 7 is a flowchart of the process when associating facility-related drawing expression information. In S71, the display processing unit 15 performs display processing on the P&ID diagram such that the range on the P&ID diagram can be specified. In step S702, the display processing unit 15 performs display processing on the three-dimensional model stored in the database server 2.

[0066] In step S703, if a 3D model corresponding to the equipment specified in the P&ID diagram is not stored (NO in step S703), the process proceeds to step S704. In step S704, the generation unit 16 generates a 3D model from the point cloud data. The generation of the 3D model is performed using any method, such as a method in which the user selects a point cloud corresponding to piping and calculates the central axis vector and diameter required for the model from the distribution, or a method in which a triangular mesh is generated from the point cloud. Once the generation unit 16 generates the 3D model, the registration unit 12 generates a unique ID and registers the unique ID information in the unique ID table 21, as well as registering the 3D model information in the 3D model DB 27 and storing the 3D model in the database server 2 (storage unit).

[0067] In step S703, if a corresponding 3D model is stored (YES in step S703), the process proceeds to step S705. Then, in step S705, the display processing unit 15 displays one or more elements of the 3D model so that the user can select the 3D model corresponding to the equipment specified in step S703.

[0068] In step S706, the display processing unit 15 displays the equipment management list based on the equipment management information, making elements in the equipment list selectable. In step S707, if equipment management information corresponding to the equipment specified in the range on the P&ID diagram is not stored (NO in step S707), the process proceeds to step S708. In step S708, the registration unit 12 registers the new equipment management information in the equipment management list DB 23. When the registration unit 12 generates new equipment management information, it generates a unique ID and registers the unique ID information in the unique ID table 21.

[0069] In step S707, if the corresponding equipment management information is stored (YES in step S707), the process proceeds to step S709. Then, in step S709, the display processing unit 15 displays the equipment management list so that individual elements can be selected, and prompts the user to select the record corresponding to the equipment specified in step S703.

[0070] In step S710, the registration unit 12 generates a range selection file. The registration unit 12 then generates a new unique ID and stores the range selection file generated in step S710 and the P&ID diagram information associated with the newly generated unique ID in the P&ID diagram DB 28. In this embodiment, each time a range selection file is generated, the P&ID diagram information with the new unique ID is registered in the P&ID diagram DB 28. The range selection file contains the range specified in step S701, the unique ID of the equipment management information selected in step S709, and the creation date and time of the range selection file, and is stored in the P&ID diagram DB 28 in association with the file name and diagram number of the P&ID diagram on which the operation was performed. The range is specified, for example, by coordinates on one or more P&ID diagrams. The shape of the range may be fixed, such as a rectangle or a circle, or it may be specified by the user. If it is specified, the shape of the range is associated with the range selection file.

[0071] In step S711, the linking unit 14 registers linking information that associates P&ID diagram information with 3D model information, and linking information that associates P&ID diagram information with equipment management information, in the unique ID linking table 22. If multiple 3D models are associated with one unique ID, a number that distinguishes the 3D model group may be added to the 3D model information to group them. Here, the unique IDs of P&ID diagram information for which no range selection file has been registered and P&ID diagram information for which a range selection file has been registered by manipulating the P&ID diagram may also be linked via the linking unit 14. Furthermore, by replacing the P&ID diagram with a spool diagram and performing the processing in steps S701 to S711, the linking unit 14 can register linking information that associates spool diagram information with 3D model information, and linking information that associates spool diagram information with equipment management information, in the unique ID linking table 22. Furthermore, for equipment-related diagrams such as panoramic images where multiple elements are unavailable for selection, the elements in the diagram can be associated with equipment management diagram information by associating them with a range selection file. The linking unit 14 may also register linking information that associates 3D model information and equipment management information. In this embodiment, a unique ID of the equipment management information is assigned to the selection range file, but a selection range file DB may be provided, and a unique ID may also be assigned to the selection range file, and the unique IDs of equipment-related diagrams such as P&ID diagrams, spool diagrams, and panoramic images where multiple elements are unavailable for selection may be associated and registered in the ID linking table 22.

[0072] <Procedure for associating equipment-related diagrams and charts with equipment-related information> Figure 8 is a flowchart of the process for associating equipment-related diagram information. In step S801, the display processing unit 15 displays the equipment management list based on the equipment management information, making elements in the equipment list selectable. In step S802, if the equipment management information for the equipment to be associated is not stored (NO in step S802), the process proceeds to step S803. In step S803, the registration unit 12 registers the new equipment management information in the equipment management list DB 23. When the registration unit 12 generates new equipment management information, it generates a unique ID and registers the unique ID information in the unique ID table 21.

[0073] In step S802, if the equipment management information to be associated is stored (YES in step S802), the process proceeds to step S804. In step S804, the display processing unit 15 displays the equipment management list so that individual elements can be selected, and prompts the user to select the record corresponding to the equipment that they want to associate with the equipment-related diagram information.

[0074] In S805, the display processing unit 15 processes the P&ID diagram to display a range on the P&ID diagram that can be specified. In S806, the display processing unit 15 processes the spool diagram to display a range on the spool diagram that can be specified. At this time, it is preferable that the P&ID diagram and the spool diagram are displayed on the same screen.

[0075] In step S807, the display processing unit 15 processes the P&ID diagram to display it in a way that allows range selection on the P&ID diagram to be accepted. In step S808, the display processing unit 15 processes the spool diagram to display it in a way that allows range selection on the spool diagram to be accepted. It is preferable that the range selected on either the P&ID diagram or the spool diagram remains drawn on the diagram after selection and can be referenced when selecting the other range. Note that the steps S807 and S808 may be reversed, and the range selection on the P&ID diagram may be made by referring to the range selection on the spool diagram.

[0076] In step S809, the registration unit 12 generates a range selection file, issues a new unique ID, and stores the P&ID diagram information associated with the generated unique ID and the range selection file in the P&ID diagram DB 28. The range selection file contains the range specified in step S807, the unique ID of the equipment management information selected in step S804, and the creation date and time of the range selection file. In step S810, the registration unit 12 generates a range selection file, issues a new unique ID, and stores the spool diagram information associated with the generated unique ID and the range selection file in the spool diagram DB 29. The range selection file contains the range specified in step S808, the unique ID of the equipment management information selected in step S804, and the creation date and time of the range selection file.

[0077] In step S811, the linking unit 14 registers linking information that associates equipment management information with P&ID diagram information, and linking information that associates equipment management information with spool diagram information, in the unique ID linking table 22. Here, the linking unit 14 may register linking information that associates the P&ID diagram information used when displaying the P&ID diagram in step S805 with the P&ID diagram information generated in step 809, and may register linking information that associates the spool diagram information used when displaying the spool diagram in step S806 with the spool diagram information generated in step 810.

[0078] <Mapping between floor plans and panoramic images> The display processing unit 15 may display a plan diagram or point cloud plan diagram so that a section or coordinates on the plan diagram can be specified, and may associate equipment management diagram information with any area on the plan diagram. In this embodiment, the display processing unit 15 further displays a panoramic image so that it can be selected, and accepts the specification of sections and panoramic images from the user. The linking unit 14 then registers the linking information having unique IDs for the sections and panoramic images in the unique ID linking table 22. When associating with coordinates on the plan diagram, for example, the display processing unit 15 may display the plan diagram so that the coordinates can be specified, and the registration unit 12 may specify the range by registering a range selection file in the plan diagram DB 24 based on the specified coordinates. In this case, the range selection file has, for example, the unique ID of the panoramic image, the creation date and time of the range selection file, and the specified coordinates.

[0079] <Matching plan diagrams and comments> Furthermore, comments are associated with the partitions and stored in the database server 2. In this embodiment, the display processing unit 15 displays the partitions in a way that allows them to be specified, and also allows comments to be entered. When a comment is entered, the registration unit 12 issues a unique ID for the comment and stores the comment information, which includes the comment ID, the comment content, and the creation date and time (the date and time the comment was made), in the database server 2. The linking unit 14 then registers the linking information, which includes the unique IDs of the partitions and comments, in the unique ID linking table 22. When associating with coordinates on the plan diagram, for example, the display processing unit 15 may display the plan diagram in a way that allows the coordinates to be specified, and the registration unit 12 may specify the range by registering a range selection file in the plan diagram DB 24 based on the specified coordinates. In this case, the range selection file includes, for example, the unique ID of the comment, the creation date and time of the range selection file, and the specified coordinates.

[0080] <Mapping external information> The display processing unit 15 may further process and display information stored in the external database 3, and may associate it with equipment-related diagram information. In this embodiment, the external database 3 includes a maintenance information DB 31 that stores maintenance information for individual pieces of equipment, and an operation status information DB 32 that stores operation status information for individual pieces of equipment. Maintenance information includes, for example, the corrosion and cracking status of piping surfaces, and the results of maintenance inspections to confirm the internal condition by non-destructive testing. The display processing unit 15 processes and displays equipment-related diagram information or equipment-related diagrams and the information stored in the external database 3 in a way that allows each to be specified, and upon receiving the specification of both, the registration unit 12 associates the information stored in the external database 3 with the equipment-related diagram information. In this embodiment, the paths of the maintenance information and operation status information are associated with the equipment management information stored in the equipment management list DB 23. It is not necessarily required that the information stored in the external database 3 be associated with the equipment management information; it may be associated with other equipment-related diagram information. Furthermore, the information stored in the external database 3 may also be managed by the registration unit 12 in the database server 2, where it issues a unique ID and is treated as equipment-related diagram information, similar to the equipment management diagrams described above.

[0081] <Operation screen> The display processing unit 15 may display multiple equipment management charts side by side based on the linked information. For example, the display processing unit 15 displays a plan diagram (or point cloud plan diagram) with selectable sections. When a section is selected, the display processing unit 15 searches the 3D model DB 27 for a 3D model containing elements associated with that section, based on the linked information, and displays it.

[0082] In this embodiment, the 3D model is directly associated with the area through the linkage information between the area and the 3D model. Furthermore, the P&ID diagram is directly associated with the 3D model through the linkage information between the 3D model and the P&ID diagram. Therefore, the area and the P&ID diagram are indirectly associated based on this linkage information. The display processing unit 15 may display not only the directly associated equipment-related diagrams but also this indirectly associated equipment management diagrams. [Explanation of symbols]
