The present invention relates to a system, method, and storage medium for maintaining and managing a building after completion.
In recent years, in the field of construction, utilization of a 3D model called BIM (Building Information Modeling) has been promoted. BIM is 3D modeling of a building to be reproduced on a computer, and a 3D model of each member can be created. BIM has been increasingly utilized at building design sites (planning, architectural design, facility design, design analysis, execution design, construction planning, and component manufacturing), however, it is said that there is a delay in utilization of BIM at building construction sites. Accordingly, the applicant has proposed a technology to utilize BIM at construction sites as described below. Based on Patent Literatures 1 to 4, a 3D model (hereinafter, referred to as “construction model”) can be created in which information on a construction process is reflected in design BIM.
However, it is considered that there is a delay in utilization of BIM not only during building construction but also after completion of building construction. After completion, it is necessary to maintain and manage the building and periodically inspect whether the building has been properly used. However, for this inspection, planning may be performed according to drawings and data at the time of completion of the building, and problems often occur in which current environment conditions of the building are not consistent with the completion drawing. As a result, problems with difficulty in planning or incorrect planning often arose.

According to a management system, management method, and storage medium of the present invention, data management for reflecting changes in environment conditions of a building in data at the time of completion of the building can be performed.
Next, preferred embodiments of the present invention will be described with reference to the drawings. The same or equivalent components, members, and processes illustrated in the respective drawings, are provided with the same reference signs, and overlapping descriptions will be omitted as appropriate.
The input/output device 2 is a general-purpose personal computer, tablet terminal, etc., including at least an arithmetic unit, a recording unit, a communication unit, a display unit, and an operation unit, and can be operated by a manager.
The operation model creating unit 5 (hereinafter, also referred to as “functional unit”) consists of electronic circuits of a CPU (Central Processing Unit), an ASIC (Application Specific Integrated Circuit), a PLD (Programmable Logic Device) such as an FPGA (Field Programmable Gate Array), etc. The functional unit may be configured inside the input/output device 2 or configured by either separate external hardware/ software. In the latter case, the functional unit can transmit and receive information to and from the input/output device 2 through a communication network.
The completion database 3, the environment database 4, and the operation database 8 are stored in the same or different server computers configured to be capable of communicating with each other through a communication network. The server computer (s) can communicate with the functional unit, and transmit and receive information to and from the functional unit.
In the completion database 3, data on construction members at the time of completion (hereinafter, referred to as “completion members”) of a building to be managed are stored. The completion database 3 includes, as illustrated in
Alternatively, it is also preferable that the completion member table 31 is created by using coordinate data in a “design correction database” disclosed in Patent Literature 1 or a “corrected construction plan database” disclosed in Patent Literature 2. When coordinate data of Patent Literature 1 and Patent Literature 2 are used, information on a construction model can be taken over, so that a “completion model” (construction model at the time of completion. A 3D model of the building at the time of completion reproduced on a computer, and data that enables creation of a 3D model of each completion member. The 3D model includes shapes of surfaces, lines, and points) can be created.
Alternatively, it is also preferable that the completion member table 31 is created from a work management system (hereinafter, referred to as “tool work management system”) disclosed in Japanese Published Unexamined Pat. Application No. 2021-173727 and the construction model creation system (hereinafter, referred to as “tool construction model creation system”) disclosed in Japanese Published Unexamined Pat. Application No. 2022-6508 proposed by the applicant. The reference signs 32 to 37 in
In the environment database 4, data on “environment conditions” after completion of the building to be managed are stored as needed. In this description, completion members after completion and objects related to the completion members (various objects other than completion members, related to the completion members in terms of coordinates) are collectively referred to as “environment conditions.” The environment database 4 includes, as illustrated in
Preferably, in order to enable information extraction based on the measuring device, information on a measuring device (camera, scanner, total station, tool, etc.) that acquired environment conditions (“environment acquisition processing”) may be stored in the environment conditions table 41. In order to enable information extraction based on time, information on a time of acquisition of environment conditions (“work time”) may be stored. In order to enable information extraction based on element attributes of environment conditions, a name of the environment conditions, or when a member ID in the completion member table 31 is assigned to coordinates, the member ID, may be stored as “element attributes information.” The element attributes information includes not only attributes information of a completion member but also attributes information of objects (such as obstacles and mobile objects (including persons/machines)) related to the completion member.
In the operation database 8, data on a completion member related to acquired environment conditions (that is, a completion member which is likely to have been changed after completion due to a change in environment conditions. Hereinafter, referred to as “operation member”) is recorded as needed. The operation database 8 stores, as illustrated in
The operation model creating unit 5 creates an “operation model” (described later) from data in the completion database 3 and the environment database 4, and creates an operation database 8. Details will be described in a management method to be described next.
Specifically, in Step S101, the operation model creating unit 5 accesses the environment database 4, reads out the environment conditions table 41, and acquires data on the environment conditions. The operation model creating unit 5 functions when a change is made in the environment conditions table 41 or when a manager accesses the environment database 4 through the input/output device 2. As the data on the environment conditions, data added since previous management processing, data which was not managed in the previous management processing, or data selected by the manager, is acquired.
Next, the processing shifts to S102, and when element attributes information of the environment conditions acquired in Step S101 includes a member ID, the operation model creating unit 5 extracts a corresponding completion member as an operation member from the completion member table 31. When there is no element attributes information, environment acquisition coordinates of the environment conditions are displayed on the input/output device 2, and based on the coordinates, the manager is prompted to extract an operation member.
Next, the processing shifts to S103, and the operation model creating unit 5 creates an “operation model” (a 3D model of a building reflecting environment conditions of the building, reproduced on a computer, and data from which each operation member can be created as a 3D model. The 3D model includes shapes of surfaces, lines, and points).
When a shape of the operation member can be obtained from the data on the environment conditions, for example, as indicated by the reference sign 6-1 in
Next, the processing shifts to Step S104, and the operation model creating unit 5 assigns an operation member ID to the operation member, and updates the operation member table 81 based on the operation model by storing the member ID of the completion member that has become the operation member, operation member coordinates, and an operation member shape in the operation member table 81.
As described above, according to the management system 1 and the management method of the present embodiment, by creating an operation model, a building can be managed by reflecting changes in environment conditions (changes based on coordinates) after completion of the building into data at the time of completion of the building. After completion of the building, it is necessary to inspect whether the building is properly operated. For this inspection, by creating a plan by using an operation model reflecting a current state of a completion member which has changed in the environment conditions, it is possible to prevent an inappropriate inspection from being made. In addition, the authority to maintain and manage a building is generally transferred from a constructor to an owner of the building, and BIM is not taken over. Therefore, analog management is performed by the owner of the building in many cases. However, by using the management system 1 and the management method of the present embodiment, BIM can also be utilized for maintaining and managing the building.

In the building in
A flow of a management method according to the second embodiment is similar to the flowchart (
Next, the processing shifts to S102, and when a member ID is included in element attributes information of the environment conditions acquired in Step S101, the operation model creating unit 5 extracts a corresponding completion member as an operation member from the completion member table 31. When there is no element attributes information, environment acquisition coordinates of the environment conditions are displayed on the input/output device 2, and based on the coordinates, the manager is prompted to extract an operation member.
Next, the processing shifts to S103, and the operation model creating unit 5 creates an operation model by using the construction model creating method of the tool construction model creation system.
In the tool construction model creation system, from coordinates of a tip end position of a tool and a member shape pattern of a construction member, a shape model (a line segment model, a quadrangle model, a circle model) representing a member shape of the construction member can be created. Information in a “vertex model table,” a “straight line model table,” a “quadrangle model table”, a “circle model table,” a “member shape pattern table,” and a “construction member component table” of a “construction model database” of the tool construction model creation system are respectively linked to member coordinates in the completion member table 31, and are stored as a completion member vertex model table 32, a completion member straight line model table 33, a completion member quadrangle model table 34, a completion member circle model table 35, a completion member shape pattern table 36, and a completion member component table 37 in the completion database 3 (refer to
For example, when it is desired to create a line segment model representing a member shape of an operation member having a straight line shape, the operation model creating unit 5 selects a point with smallest coordinates as a “work start point” among environment acquisition coordinates extracted in Step S102, selects three points whose coordinates are near the work start point as “candidate point 1, candidate point 2, and candidate point 3,” selects line segments connecting the work start point and the candidate points 1, 2, and 3 as “candidate line segment 1, candidate line segment 2, and candidate line segment 3,” and determines line segments orthogonal to each other as “definite line segments,” and concerning line segments not orthogonal to each other, determines only line segments on a straight line as “definite line segments.” This work is performed for all environment acquisition coordinates, and line segments determined as “definite line segments” are set as a line segment model of the operation member, that is, an operation model. When it is desired to create a quadrangle model representing a member shape of a rectangular operation member, among environment acquisition coordinates extracted in Step S102, a point with smallest coordinates is selected as a “temporary start point,” and among the environment acquisition coordinates, a point whose x and y coordinates are equal to those of the temporary start point is selected as a “candidate point,” and among candidate points, a point closest to the origin of the x, y, and z axes is set as a “work start point 1,” a candidate point closest to the work start point 1 is selected as a “temporary candidate point,” a candidate point that is on a straight line passing through the work start point 1 and the temporary candidate point and furthest from the work start point 1 is selected as a “work start point 2, ” a candidate point that is orthogonal to a straight line passing through the work start point 1 and the temporary candidate point, passes through the work start point 1 (T1), and is furthest from the work start point 1, is selected as a “work start point 3,” a candidate point that is orthogonal to a straight line passing through the work start point 1 and the temporary candidate point, passes through the work start point 2 (T2), and is furthest from the work start point 2, is selected as a “work start point 4,” and a set of line segments passing through the work start points 1 to 4 (T1 to T4) is set as a quadrangle model of the operation member, that is, an operation model. When it is desired to create a circle model representing a member shape of a circular operation member, environment acquisition coordinates extracted in Step S102 are projected on a plane perpendicular to the xy plane, points with z coordinates within a certain distance are grouped, and two pairs of arbitrary two points are selected from the grouped points, normal lines orthogonal to line segments passing through the respective points and passing through midpoints of the line segments are created, and a point at which the normal lines cross each other is calculated as a “center point,” a diameter is calculated by doubling a distance between the center point and an arbitrary point on the xy plane (radius), and the result is set as a circle model representing the operation member, that is, an operation model. In the case of the shelf Sh (operation member) in
Next, the processing shifts to Step S104, and the operation model creating unit 5 assigns an operation member ID to the operation member, and based on the operation model, updates the operation member table 81 by storing the member ID of the completion member that has become the operation member, the operation member coordinates, and the operation member shape in the operation member table 81.
As described above, according to the management system 1′ and the management method of the present embodiment, the same effect as that of the first embodiment can be obtained, and by combination with the tool work management system 9, a change in environment conditions of the building (change based on coordinates) is automatically acquired, and the environment conditions table 41 is automatically created. By using the tool work management system 9, not only the environment acquisition coordinates but also items of environment acquisition processing, work time, and attributes information can be provided in the environment conditions table 41. Therefore, the operation model creating unit 5 can use the tool construction model system, and the management system 1′ can be more effectively used.
In the management system 1″ of the present embodiment, the environment database 4 further includes an environment confirmation table 42. In the environment confirmation table 42, data on a changed environment conditions is recorded as needed. In the environment confirmation table 42, new identification information (change confirmation ID) for the changed environment conditions, a member ID linked to the completion member table 31, environment acquisition coordinates of the changed environment conditions, the presence/absence of a change, and a date and time (confirmation date and time) for which a change was confirmed, are stored in association with each other. The environment confirmation table 42 is created by the change point extracting unit 6. In the management system 1″ of the present embodiment, the completion database 3 includes the completion member vertex model table 32, the completion member straight line model table 33, the completion member quadrangle model table 34, the completion member circle model table 35, the completion member shape pattern table 36, and the completion member component table 37 (refer to
In the management system 1″, when management processing (extraction of the presence/absence of a change) is started, in Step S301, the change point extracting unit 6 accesses the completion database 3, reads out the completion member table 31, and creates a completion model.
Next, the processing shifts to S302, and the change point extracting unit 6 accesses the environment database 4, reads out the environment conditions table 41, and acquires environment acquisition coordinates. As environment acquisition coordinates, coordinates added since previous management processing, coordinates which were not managed in the previous management processing, or coordinates selected by the manager are all acquired.
Next, the processing shifts to S303, and the change point extracting unit 6 displays the completion model on the input/output device 2 and prompts the manager to select one completion member whose change is to be confirmed (hereinafter, referred to as “change point confirming member”).
Next, the processing shifts to S304, and the change point extracting unit 6 acquires data on a member shape of the change point confirming member selected in S303 from the completion database 3 (any of or a combination of the completion member vertex model table 32, the completion member straight line model table 33, the completion member quadrangle model table 34, the completion member circle model table 35, the completion member shape pattern table 36, and the completion member component table 37).
Next, the processing shifts to S305, and the change point extracting unit 6 prompts the manager to select one point whose change is to be confirmed (hereinafter, referred to as “confirming point”) among the environment acquisition coordinates, and determines whether coordinates of the confirming point fall within a member range of the change point confirming member. When the confirming point is of the change point confirming member, the processing shifts to Step S307 (YES), and when the confirming point is not of the change point confirming member, the processing shifts to Step S306 (NO) . When the change point extracting unit 6 automatically selects a confirming point, selection is made according to a predetermined rule so as not to cause overlapping. For example, when environment acquisition result IDs (refer to
In the case where the processing shifts to Step S306, the confirming point is not of the change point confirming member, so that for the confirming point, the change point extracting unit 6 assigns new identification information (change confirmation ID), and stores the change confirmation ID and environment acquisition coordinates of the confirming point in the environment confirmation table 42 together with a member ID (linked to the completion member table 31) of the change point confirming member, and determines “Changed,” and the processing shifts to Step S307.
When the processing shifts to Step S307, the change point extracting unit 6 determines whether confirming point confirmation has finished for all completion members of the completion model. When there are completion members for which confirmation has not finished yet, the processing returns to Step S303, and another completion member is selected as a change point confirming member and the flow is repeated. After confirmation is finished for all completion members, the processing shifts to Step S308.
When the processing shifts to Step S308, the change point extracting unit 6 determines whether all environment acquisition coordinates acquired in S302 have been completely confirmed. When there are coordinates that have not been confirmed yet, the processing returns to Step S302, different coordinates are selected as a confirming point, and the flow is repeated. After all coordinates are confirmed, the management processing is ended.
As described above, according to the management system 1″ and the management method of the present embodiment, a change in environment conditions since completion, that is, a displacement of a completion member or an element that had not been present at the time of completion can be extracted.
It is also preferable that in the environment confirmation table 42, confirmation attributes (confirmed/unconfirmed) are further provided, and “Confirmed” is assigned to an element that the manager confirmed in Step S402 described above, and an element which has “Changed” and to which “Unconfirmed” is assigned as confirmation attributes is extracted in Step S401. It is preferable that when “Confirmed” is assigned, a date and time of the confirmation are also stored.
Preferred embodiments and modifications of the present invention have been described above, and the embodiments and modifications can be combined based on the knowledge of a person skilled in the art, and such a combined embodiment is also included in the scope of the present invention.
In the embodiments and modifications, a management system and method for reflecting changes in environment conditions after completion of a building in “data of building at the time of completion” have been described, however, the present invention is also a system and method capable of managing a building by reflecting changes in environment conditions of the building in a previously created operation model and continuously updating the operation model. Therefore, BIM can be utilized in various operations ranging from design planning to repair of the building, that is, an entire life cycle of the building.
