[0019] [Figure 1] This figure illustrates an overview of a building information aggregation system according to an embodiment of the present invention. [Figure 2] This block diagram shows the functional configuration of a building information aggregation system according to an embodiment of the present invention. [Figure 3] This figure shows an example of a list screen in a building information aggregation system according to an embodiment of the present invention. [Figure 4] This figure shows examples of building images and specific part images in a building information aggregation system according to an embodiment of the present invention. Figure 4(a) shows an example of a building image, and Figure 4(b) shows an example of a specific part image. [Figure 5] This is a flowchart showing the building information aggregation process performed in the building information aggregation system according to an embodiment of the present invention. [Modes for carrying out the invention]

[0020] Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the attached drawings.

[0021] <Embodiment> [Overview of the Building Information Aggregation System] Figure 1 is a diagram illustrating an overview of a building information aggregation system according to an embodiment of the present invention. This document provides an overview of the Building Information Aggregation System 1 (hereinafter also simply referred to as "the System" or "this System").

[0022] The building information aggregation system 1 includes a building information aggregation device 100 and terminals 200 connected to the building information aggregation device 100 via a network (e.g., cloud, internet, company LAN, etc.).

[0023] This system aggregates information related to structures (such as buildings and bridges), and one example of its use is in the maintenance of these structures. Information related to structure maintenance includes not only design drawings (architectural drawings, structural drawings, equipment drawings, etc.) and specifications, but also records of post-construction renovations and maintenance, which accumulate over time. By using this system for such structure maintenance, it becomes possible to aggregate information related to structure maintenance and improve the efficiency of maintenance work and management. Furthermore, this system can be used to aggregate a wide variety of information related to structures, not just for structure maintenance, and to make this information available for use.

[0024] In this system, for example, a user accesses the building information aggregation device 100 via terminal 200, sends and receives various data to and from the building information aggregation device 100, aggregates information about buildings, and displays the aggregated data (building images, specific information, specific part images, etc., as described later) on terminal 200.

[0025] In this system, the building information aggregation device 100 receives building drawing data (for example, CAD data, preferably BIM (Building Information Modeling) data that defines the attributes of the objects that make up the building (such as the location, dimensions, and specifications of the objects)) from the terminal 200.

[0026] If the received drawing data contains information indicating various locations within the building (for example, information indicating the location of a room or entrance within the building), the building information aggregation device 100 sets each of these locations as a specific location within the building. Note that the specific locations may be arbitrarily set by the user in the drawing data.

[0027] Furthermore, the building information aggregation device 100 acquires specific information related to a specific location from the terminal 200 (for example, the specifications of the room, information showing the history of renovations to the room, records of maintenance to the room, etc.).

[0028] Furthermore, the building information aggregation device 100 constructs a database that associates a set specific location with the acquired specific information. When the building information aggregation device 100 acquires further specific information about a certain specific location (for example, when records of maintenance performed as needed are acquired), it updates the database.

[0029] Furthermore, the building information aggregation device 100 may acquire specific part image data (for example, 3D data generated based on an image taken by an imaging device at a specific location of an actual building (e.g., the entrance)) for displaying a specific part image showing details of a specific part at a specific location. The building information aggregation device 100 associates the acquired specific part image data with the specific location and specific information in the database.

[0030] The building information aggregation device 100 displays a list screen on the terminal 200 that displays specific information in a list format based on the database constructed in the building information aggregation device 100. On the list screen, the specific information is classified by type (in the example shown in Figure 1, specifications, drawings, maintenance, furniture and fixtures, etc.) and displayed in a list format for each classification.

[0031] Furthermore, the building information aggregation device 100 displays a building image based on drawing data on the terminal 200. More specifically, the terminal 200 displays the portion of the building image that includes a specific location associated with the specific information selected on the list screen.

[0032] Furthermore, the building information aggregation device 100 displays a specific part image on the terminal 200, showing details of a specific part at a specific location. Specifically, it displays a specific part image associated with the specific information selected on the list screen.

[0033] According to this building information aggregation system 1, a specific location indicating a particular place in a building is associated with specific information related to that location, a list screen is displayed that shows the specific information in a list format, and the portion of the building image that includes the specific location associated with the specific information selected on the list screen is displayed. Therefore, the user can comprehensively grasp the specific information on the list screen and confirm the location of the building related to each piece of specific information in the building image. Therefore, it becomes possible to provide a building information aggregation system that comprehensively grasps information about buildings and allows for the confirmation of the location of each piece of information within the building.

[0034] [System Functional Configuration] Next, we will explain the system's functional configuration. Figure 2 is a block diagram showing the functional configuration of a building information aggregation system according to an embodiment of the present invention.

[0035] The building information aggregation system 1 comprises a building information aggregation device 100 and a terminal 200 connected to the building information aggregation device 100 via a network (e.g., the Internet, an internal LAN, etc.), and is capable of connecting to external devices (e.g., an imaging device, etc.). In addition, the building information aggregation system 1 may also include a storage means 300 connected to the building information aggregation device 100 via a network, separate from the building information aggregation device 100.

[0036] (Building Information Aggregation Device) The building information aggregation device 100 includes a drawing data receiving means 110, a specific location setting means 120, a specific information acquisition means 130, a specific part image acquisition means 140, an association means 150, and a display control means 160, and is connected to a terminal 200 and an external storage means 300 via a network.

[0037] The drawing data receiving means 110 receives drawing data for displaying a building from the terminal 200 and stores it in the storage means. The drawing data receiving means 110 may also read drawing data pre-stored in the storage means or storage means 300 of the building information aggregation device 100 at the user's operation and store it in the storage means as drawing data to be used in this system. In this embodiment, the drawing data is, for example, CAD data, and preferably 3D data such as BIM (Building Information Modeling) data that defines the attributes of the objects constituting the building (such as the position, dimensions, and specifications of the objects), but it may also be 2D data.

[0038] The specific location setting means 120 sets each location indicated by the information (for example, information indicating the location of a room or entrance in the building) in the received drawing data as a specific location in the building. Note that the specific locations may be arbitrarily set by the user in the drawing data.

[0039] The specific location setting means 120 stores in the storage means a correspondence between specific location identification information (for example, information indicating the name of a location such as a room or entrance in a building) that identifies a specific location and location information of that specific location in the drawing data (for example, information indicating the coordinates of that location on the drawing data).

[0040] The specific information acquisition means 130 acquires specific information relating to a specific location set by the specific location setting means 120 from the terminal 200. The specific information acquisition means 130 may also read specific information pre-stored in the storage means or storage means 300 of the building information aggregation device 100 at the user's operation. Furthermore, if the drawing data received by the drawing data receiving means 110 includes specifications (such as finish specifications, shape, and dimensions) of a specific location in the building (for example, a room or entrance in the building), the specific information acquisition means 130 may acquire this information as specific information.

[0041] The specific information acquisition means 130 acquires specific information associated with specific location identification information (for example, information indicating the name of a location such as a room or entrance in a building) that identifies a specific location, and stores it in the storage means.

[0042] In this embodiment, "specific information" includes, for example, information indicating the specifications of a building (e.g., finishing specifications, shape, dimensions, etc.), information indicating drawings of the building (e.g., floor plans for each floor, equipment drawings, etc.), information related to the maintenance of the building (records of renovations carried out after construction, records of maintenance and inspections carried out as needed, etc.), and information related to furniture and fixtures placed in the building (information indicating the product name, specifications, manufacturer, etc. of furniture and fixtures).

[0043] Thus, the specific information acquisition means 130 can acquire multiple types of specific information, but it is not limited to this, and may acquire only one type of specific information (for example, information related to the preservation of buildings). By specializing in one type of specific information, it is possible to reduce the overall amount of data and the processing load on this system and the terminal 200.

[0044] The specific part image acquisition means 140 generates specific part image data for displaying a specific part image showing details of a specific part at a specific location set by the specific location setting means 120, based on image data received from an imaging device, which is an external device connected to the building information aggregation device 100, and stores it in the storage means. The specific part image data is data for displaying a specific part in 3D, and is, for example, 3D data generated based on an image taken by an imaging device at a specific location of an actual building (e.g., the entrance). The specific part image acquisition means 140 may directly acquire the specific part image data from the imaging device, which is an external device, or it may read specific part image data that has been pre-stored in the storage means or storage means 300 of the building information aggregation device 100 through user operation.

[0045] The specific part image acquisition means 140 generates specific part image data for displaying images of specific parts that can be moved or have their viewpoint changed in response to user operations within a virtual space of a building.

[0046] The association means 150 associates specific information related to a specific location, acquired by the specific information acquisition means 130, with the specific location set by the specific location setting means 120. Furthermore, if the specific part image acquisition means 140 has acquired specific part image data, the association means 150 associates the specific part image data (specific part image) with the specific location and specific information.

[0047] In detail, the association means 150 constructs a database that associates the location information of a specific location with the specific information of a specific location, and stores it in the storage means. Furthermore, if the specific part image acquisition means 140 has acquired specific part image data, the association means 150 also associates the specific part image data with the specific location identification information in the database.

[0048] In this system, the building information aggregation device 100 stores user identification information in a storage means to identify users who can access the building information aggregation device 100. Users can then access the building information aggregation device 100 and log in to this system by inputting the user identification information via the terminal 200.

[0049] The association means 150 may further set access rights to the database for multiple users for each specific location or piece of specific information. In this case, for example, user identification information of users who can access each specific location or piece of specific information may be associated with it.

[0050] Figure 3 shows an example of a list screen in a building information aggregation system according to an embodiment of the present invention. The display control means 160 generates a list screen that displays the specific information acquired by the specific information acquisition means 130 in a list format, based on the database constructed by the association means 150, and displays it on the input / output means 230 of the terminal 200. If there are multiple types of specific information in the database, the display control means 160 displays a list screen classified by type (in the example shown in Figure 3, maintenance, furniture and equipment).

[0051] In detail, the list screen generated by the display control means 160 associates specific location identification information (name of specific location, etc.: in the example shown in Figure 3, waiting room, 1st floor office), specific information and whether or not a specific part image exists (in the example shown in Figure 3, "○" indicates that a specific part image exists, and "-" indicates that a specific part image does not exist), and users who have access rights to each specific location and each piece of specific information (in the example shown in Figure 3, users A, B, C), and displays the specific information in a list format.

[0052] In the example shown in Figure 3, the list screen only displays the name of the specific information (for example, "2019 Inspection Record"). If, for example, the user selects the name of this specific information on the list screen displayed on terminal 200 (for example, by touching the name of the specific information), the content of that specific information will be displayed. Alternatively, the content of the specific information may also be displayed on the list screen.

[0053] Furthermore, the display control means 160 generates a building image based on the drawing data received by the drawing data receiving means 110 and displays it on the input / output means 230 of the terminal 200. If the drawing data is 3D data of the building (e.g., BIM data), the display control means 160 generates a building image that allows the user to move around in the virtual space of the building and change their viewpoint according to user operations. If the drawing data is 2D data of the building, the display control means 160 generates a building image that is represented in a planar manner.

[0054] Furthermore, the display control means 160 displays the specific part image based on the specific part image data generated by the specific part image acquisition means 140 on the input / output means 230 of the terminal 200.

[0055] Figure 4 shows an example of a building image and a specific part image in a building information aggregation system according to an embodiment of the present invention. Figure 4(a) shows an example of a building image, and Figure 4(b) shows an example of a specific part image. The example shown in Figure 4 illustrates an example of a building image and a specific part image that are displayed when the waiting room is selected as a specific location on the list screen (see Figure 3) during operation of terminal 200 by the user.

[0056] The display control means 160 displays, for example, a link R1 to specific information associated with the specific location (a waiting room in the example shown in Figure 4) by the association means 150, and a link R2 to specific part image data associated with the specific location by the association means 150, in a building image (see Figure 4(a)).

[0057] Furthermore, the display control means 160 displays, for example, a link R1 to specific information associated with the specific location (in the example shown in Figure 4, the waiting room) by the association means 150, and a link R3 to the specific location in the building image associated with the association means 150, in the image of a specific part (see Figure 4(b)).

[0058] A user of this system, for example, logs in to the system using their user identification information and displays a list screen (see Figure 3) on terminal 200. The user then selects a specific location from the ledger of the type appropriate to the purpose on the list screen. If the user's user identification information is associated with a user who can access that specific location (in the example shown in Figure 3, if the user is displayed in the access rights section), the display control means 160 displays the building image shown in the example in Figure 4(a) on terminal 200, for example, if the waiting room is selected as the specific location. Similarly, if the display control means 160 selects "○" in the column for the image of a specific part of the waiting room (specific location), for example, the image of the specific part shown in the example in Figure 4(b) on terminal 200.

[0059] Furthermore, the display control means 160 displays a list screen (see Figure 3) or a file showing the content of specific information at the specific location on the terminal 200 when link R1 is selected by the user in the building image (see Figure 4(a)) (for example, by touching link R1), and displays a specific part image (see Figure 4(b)) on the terminal 200 when link R2 is selected (for example, by touching link R2).

[0060] Furthermore, the display control means 160, when the user selects link R1 in a specific part image (see Figure 4(b)) (for example, by touching link R1), displays a list screen (see Figure 3) or a file showing the content of specific information at that specific location on the terminal 200. When link R3 (for example, by touching link R3) is selected, the terminal 200 displays the portion of the building image that includes that specific location (see Figure 4(a)).

[0061] Furthermore, the building information aggregation device 100 may also be equipped with analysis means, which may aggregate and analyze the content of specific information, and display an aggregated and analyzed screen on the terminal 200, in which the results of the aggregation and analysis are visualized in graphs or the like.

[0062] Furthermore, the display control means 160 may simultaneously display all or part of the list screen, building images, specific part images, and aggregation / analysis screen on the terminal 200, or display them individually.

[0063] (terminal) The terminal 200 is comprised of, for example, a smartphone, tablet, or personal computer, and includes a control means 210, a transmission / reception means 220, and an input / output means 230, which is an example of a display means.

[0064] Based on user operations, the control means 210 transmits user identification information, drawing data, specific information, and specific part image data to the building information aggregation device 100 via the transmission / reception means 220.

[0065] The input / output means 230 consists of, for example, an input means such as a touch panel or keyboard and a display means such as a display. Under the control of the control means 210, it displays a list screen (see Figure 3), a file showing the content of specific information, a building image (see Figure 4(a)), and a specific part image (see Figure 4(b)) based on various information received from the building information aggregation device 100.

[0066] In this embodiment, the building information aggregation device 100, which aggregates information related to buildings, and the terminal 200, which transmits information and displays the aggregated information, have been described as separate devices. However, the invention is not limited to this, and the terminal 200 may include some or all of the functional configurations of the building information aggregation device 100.

[0067] The functional configuration of this system described above is merely an example, and a single functional block (database and functional processing unit) may be divided, or multiple functional blocks may be combined into a single functional block. Each functional processing unit is realized by a computer program (for example, core software or an application that causes the CPU to execute the various processes described above) stored in a storage device (storage means) such as ROM (Read Only Memory), flash memory, SSD (Solid State Drive), or hard disk, which is read by the CPU (Central Processing Unit) built into the device or terminal, and executed by the computer program. In other words, each functional processing unit is realized by this computer program reading and writing necessary data such as tables from a database (DB) stored in the storage device or from a storage area in memory, and, if necessary, controlling related hardware (for example, input / output devices, display devices, communication interface devices). Furthermore, the database (DB) in the embodiments of the present invention may be a commercial database, but it also means a mere collection of tables and files, and the internal structure of the database itself is not specified.

[0068] [Building Information Aggregation Processing] Next, we will explain the building information aggregation process performed by this system. In the following processing flow diagram (flowchart), the processing order of each step may be changed as long as the relationship between the input and output of each step is not compromised. Figure 5 is a flowchart showing the building information aggregation process performed in the building information aggregation system according to an embodiment of the present invention.

[0069] In step S1, the drawing data receiving means 110 receives drawing data for displaying a building from the terminal 200 and stores it in the storage means.

[0070] In step S2, the specific position setting means 120 sets each position indicated by the information indicating each position of the building in the drawing data received by the drawing data receiving means 110 in step S1 as a specific position indicating a specific location of the building.

[0071] In step S3, the specific information acquisition means 130 acquires specific information from the terminal 200 regarding the specific location set by the specific location setting means 120 in step S2.

[0072] In step S4, the specific part image acquisition means 140 generates specific part image data for displaying a specific part image that shows the details of a specific part at a specific location set by the specific location setting means 120 in step S2, based on image data received from an imaging device, which is an external device connected to the building information aggregation device 100, and stores it in the storage means.

[0073] In step S5, the association means 150 constructs a database that associates the specific location set by the specific location setting means 120 in step S2 with the specific location information acquired by the specific information acquisition means 130 and the specific location image acquisition means 140 in step S4.

[0074] In step S6, the display control means 160, in response to user operation, generates a list screen (see Figure 3) that displays the specific information acquired by the specific information acquisition means 130 in step S3 in a list format, based on the database constructed by the association means 150 in step S5, and displays it on the input / output means 230 of the terminal 200.

[0075] Furthermore, in this step, the display control means 160 reads the drawing data received by the drawing data receiving means 110 in step S1, generates a building image (see Figure 4(a)) based on the drawing data, and displays it on the input / output means 230 of the terminal 200. More specifically, in response to user operation, the display control means 160 displays on the input / output means 230 of the terminal 200 a portion of the building image that includes a specific location associated with specific information.

[0076] Furthermore, in this step, the display control means 160 displays the specific part image based on the specific part image data acquired by the specific part image acquisition means 140 in step S4 on the input / output means 230 of the terminal 200. More specifically, the display control means 160 displays the specific part image associated with specific information on the input / output means 230 of the terminal 200 in response to user operation.

[0077] According to this building information aggregation system 1, a specific location indicating a particular place in a building is associated with specific information related to that location, and a list screen is displayed that shows the specific information in a list format. By displaying the specific information in a list format in this way, it becomes possible to visualize multiple pieces of specific information at a glance, and to grasp the relative positions of the specific information. Furthermore, according to the information aggregation system 1, the portion of the building image that includes the specific location associated with the specific information selected on the list screen is displayed. Therefore, the user can comprehensively grasp the specific information on the list screen and confirm the location of the building related to each piece of specific information in the building image. Therefore, it becomes possible to provide a building information aggregation system that comprehensively grasps information about buildings and allows for the confirmation of the location of each piece of information within the building.

[0078] Furthermore, the building information aggregation system 1 can display a list screen that classifies multiple types of specific information by type. This allows users to quickly and comprehensively grasp the types of specific information that suit their purpose and to confirm the location of the building related to each type of specific information in the building image.

[0079] Furthermore, according to the building information aggregation system 1, users can, for example, check the building image if they want to confirm the location of specific information within a building, and check images of specific parts if they want to check in more detail.
