<System configuration>
FIG. 1 is a diagram illustrating an example of a configuration of a system according to the present embodiment. The system in FIG. 1 includes an administrator device 1, an information storage device 2, and a viewer device 3, and these components are connected via a network 4 such as the Internet. The manager device 1 is a computer used by a manager such as a building manager or a construction worker. The manager device 1 receives input from the user such as maintenance history such as patrol records and inspection records in the building, repair history indicating the progress of construction, and transmits the input to the information storage device 2.

The information storage device 2 is used for data related to BIM (Building Information Modeling) including a three-dimensional (3D) model of a building and attribute information such as the design and cost of the building, and work related to maintenance of the building. It is a computer that accumulates plans, implementation histories, etc. Here, BIM is a system that uses a 3D model and attribute information of a building in a unified process from design to construction and maintenance. The 3D model is generated from, for example, a building design book (that is, based on the structure of the building), and can visually represent the completed state of the building. Then, the information storage device 2 outputs the stored information in response to a request from another computer.

  The browser device 3 is a computer used by a viewer of information such as an owner of a building. For example, software for displaying the BIM is installed in the viewer device 3, and information acquired from the information storage device 2 via the network 4 is attached to the 3D model (also referred to as “BIM model”). It can be displayed as information.

<Functional configuration of information storage device>
FIG. 2 is a functional block diagram illustrating an example of the information storage device 2. The information storage device 2 includes a collection unit 21, a reflection unit 22, an output unit 23, and a basic information storage unit 24. The collection unit 21 receives input of data for recording a plan and execution of work related to the maintenance of the building from the manager device 1 via the network 4 and accumulates it as management history information. Specifically, the collection unit 21 includes an input reception unit 211, an information update unit 212, and a history information storage unit 213. The input receiving unit 211 receives data input from the administrator device 1 via the network 4. The information update unit 212 stores the input management history information in the history information storage unit 213 in association with identification information for specifying the building and the components of the building. In the present embodiment, the building component refers to the inside of a building that is partitioned physically or for purposes (in other words, functionally), such as a room, a hallway, a hall, a staircase, or the like that constitutes a building. It means the space. In the BIM model according to the present embodiment, a space in a building is defined by a set of elements such as walls, doors, windows, floors, ceilings, lighting, and air conditioners, which are finer components than a room, for example. The management history information of each element can be displayed in an aggregated manner in units of components indicating a space such as a room.

FIG. 3 is a diagram illustrating an example of a management history table stored in the history information storage unit 213. The management history table in FIG. 3 includes items such as building identification information, sections, places, work types / objects, date and time, and progress. In the building identification information field, identification information for uniquely specifying a building is registered. In the section field, for example, identification information for uniquely identifying an area in the specified building, such as the number of floors, for narrowing the work target step by step is registered. In the place field, for example, identification information for uniquely specifying an area that is a space in a specific section, such as a room, for narrowing down the target of work in stages. In the field of work type / target, information indicating the type of work, such as repairs, deterioration over time, requested construction, legal internal / external inspection, and operations such as window glass and doors, air conditioners, elevators, etc. existing at the specified location Information for specifying the target is registered. In the date / time field, the date and time when the record is registered are registered. In the progress field, information indicating stages such as input (plan), investigation, estimation, construction, follow-up, and completion is registered. The management history table may further include a budget, a person in charge, and other items. Such information is registered by the user of the administrator apparatus 1 selecting from choices (for example, pull-down menu) or inputting a character string freely.

  In addition, when the management history information is input, the reflecting unit 22 in FIG. 2 reflects the added information on data handled by the BIM (also referred to as “BIM data”). Specifically, the update detection unit 221 accesses the history information storage unit 213 at a predetermined timing to check whether information has been added, or receives a notification from the information update unit 212 that information has been added. The management history information is updated. The BIM data generation unit 222 is a 3D model (marker) indicating that the management history information associated with the component exists in the component of the building (for example, the room where the construction is performed). For convenience, it is also referred to as a “3D object”). In the present embodiment, the marker is also referred to as a “pin”. The details of the management history information may be displayed in cooperation with the 3D object (for example, a link).

  FIG. 4 is a diagram illustrating an example of an attribute table that stores attributes set for the 3D model included in the BIM data. The attribute table in FIG. 4 includes items such as 3D model identification information, building identification information, sections, places, and objects. In the 3D model identification information field, identification information for uniquely specifying the 3D model in a predetermined unit is registered. For example, it is assumed that a record of the attribute table is registered for each part of the 3D model such as a wall, a window, a door, a pillar, and a floor surface. In the building identification information field, identification information for uniquely specifying a building is registered. In the section field, for example, identification information for uniquely specifying the space in the specified building, such as the number of floors, is registered. In the place field, for example, identification information for uniquely specifying a space in the specified section (that is, a component of a building) such as a room, a hallway, a hall, or a staircase is registered. In the field of the object, what the 3D model represents, such as a wall, a window, a door, a pillar, or a floor surface, is registered. In addition, various items relating to design and construction may be associated with each other. The 3D model also has information on coordinates arranged in a predetermined coordinate system.

FIG. 5 is a diagram illustrating an example of a marker table for registering information on 3D objects generated by the information update unit 212. The marker table in FIG. 5 includes items such as object identification information, building identification information, sections, places, shapes / colors, links, and the like. Information for uniquely identifying the created marker is registered in the object identification information field. In the building identification information field, identification information for uniquely specifying a building is registered. In the section field, for example, identification information for uniquely specifying the space in the specified building, such as the number of floors, is registered. In the place field, for example, identification information for uniquely specifying a space in the specified section, such as a room, a hallway, a hall, or a staircase, is registered. Information indicating the shape and color of the marker is registered in the shape / color field. For example, when the management history information relates to aging deterioration, a marker having a tetrahedral shape is generated. If the management history information is related to repair work, a hexahedral marker is generated. When the management history information is related to the requested construction, a marker having a spherical shape is generated. If the management history information is related to others, a marker having an octahedral shape is generated. For example, when the progress is being input, the marker is pink. Similarly, when the progress is under investigation, the marker is yellow, when the progress is under estimation, the marker is green, when the progress is under construction, the marker is blue, and the progress is monitored. If the progress is complete, the marker is white. The user may be able to change the shape and color of the marker. In addition, the coordinates for drawing the marker may be registered, or the marker may be drawn at the center of gravity of a place such as a room, hallway, hall, or staircase without registering the coordinates. Note that the center of gravity of a place can be calculated as a center of gravity coordinate of a space having a 3D model such as a wall registered in association with the place in the attribute table and having the 3D model as an outer edge. In the link field, a link to management history information stored in the history information storage unit 213, which is displayed when the marker is selected, is registered. In the case where a plurality of stages of progress status records are registered in the management history table, for example, one marker is generated based on the latest status record among a series of records from input to completion. To do.
