Description

[Technical field]

[0001] The present disclosure relates to an information management device, an information management method, and an information management program for identifying an area in a building to which legal provisions apply. [Background technology]

[0002] Building design is regulated by laws such as the Building Standards Act, Fire Service Act, City Planning Act, and Real Estate Transactions Act to ensure the safety, fire prevention, environmental friendliness, and public interest of buildings. Buildings that do not comply with legal regulations will not be able to obtain construction confirmation or use permission.

[0003] For this reason, an information processing device that outputs information on laws and regulations related to construction works in accordance with information related to individual construction works has been considered (see Patent Document 1). The information processing device described in this document acquires information related to construction works. Next, when the acquired information related to construction works is input, the information on laws and regulations related to construction works is output from the information related to construction works using a trained model.

[0009] An embodiment of an information management device, an information management method, and an information management program will be described below with reference to Fig. 1 to Fig. 6. In this embodiment, a case where an area to which a legal provision is applied is specified in a building drawing as a building image will be described. As shown in FIG. 1, an information management device A1 of this embodiment includes a user terminal 10 and a management device 20 that are connected to each other via a network.

[0010] (Hardware configuration description) 2, a hardware configuration of an information processing device H10 constituting the user terminal 10 and the management device 20 will be described. The information processing device H10 includes a communication device H11, an input device H12, a display device H13, a storage device H14, and a processor H15. Note that this hardware configuration is an example, and it is also possible to realize the information processing device H10 using other hardware.

[0011] The communication device H11 is an interface that establishes a communication path with other devices and transmits and receives data. The input device H12 is a device that accepts input of various information. The display device H13 is a display or the like that displays various information.

[0012] The storage device H14 is a storage device that stores data and various programs for executing various functions of the user terminal 10 and the management device 20. Examples of the storage device H14 include a ROM, a RAM, and a hard disk.

[0013] The processor H15 uses programs and data stored in the storage device H14 to control each process in the user terminal 10 and the management device 20. Examples of the processor H15 include a CPU and an MPU. The processor H15 expands programs stored in a ROM or the like into a RAM and executes various processes for each process.

[0014] The processor H15 is not limited to a processor that performs software processing for all the processes it executes. For example, the processor H15 may include a dedicated hardware circuit (e.g., an application specific integrated circuit (ASIC)) that performs hardware processing for at least a part of the processes it executes. That is, the processor H15 may be configured as follows:

[0015] [1] One or more processors that operate according to a computer program (software). [2] One or more dedicated hardware circuits that perform at least some of the various processes [3] Circuits that include combinations of these The processor includes a CPU and memory, such as RAM and ROM, that stores program codes or instructions configured to cause the CPU to execute processes. Memory, i.e., computer-readable media, includes any available media that can be accessed by a general-purpose or special-purpose computer.

[0016] (Information management device A1) The information management device A1 will be described with reference to FIG. The user terminal 10 is a computer terminal used by a user.

[0017] The management device 20 is a computer system that specifies the application area of ​​the legal provisions. The management device 20 includes a control unit 21, a building information storage unit 22, a legal provision information storage unit 23, a teacher information storage unit 24, and a learning result storage unit 25.

[0018] The control unit 21 performs processes (including an information acquisition stage, an analysis stage, a learning stage, a prediction stage, etc.) described below. By executing a processing program for this purpose, the control unit 21 functions as an information acquisition unit 211, an analysis unit 212, a learning unit 213, a prediction unit 214, etc.

[0019] The information acquisition unit 211 executes a process of acquiring information about a building. The analysis unit 212 executes a process of analyzing building information. The learning unit 213 executes a process of generating a prediction model by machine learning using teacher information. The prediction unit 214 executes a process of predicting the application area of ​​the legal provision using a prediction model.

[0020] The building information storage unit 22 records building information on existing buildings based on the confirmation application documents submitted when applying for building confirmation based on the Building Standards Act. This building information is recorded in advance as teacher information before learning. The building information includes information on the building summary information, building drawings (building image information), building confirmation certificate, etc. for each building. If the building has been renovated, the information includes the building summary information, building drawings, building confirmation certificate, etc. at the time of the renovation.

[0021] The building summary information is information related to the overview of a building. This building summary information includes information on the construction year, site, use, size, structure, facilities, etc., described in the architectural plan summary of the building.

[0022] The building drawings include floor plans, elevations, cross sections, etc. of the building. They may also include electrical equipment drawings, water supply and drainage equipment drawings, fire protection equipment drawings, and firefighting equipment drawings. A building confirmation certificate is a certificate indicating that the building official or a designated inspection agency has approved that the building plan in the confirmation application documents complies with laws and regulations.

[0023] The legal provision information storage unit 23 records legal provision information related to legal provisions for buildings. This legal provision information is recorded when a legal provision is enacted or revised. This legal provision includes, for example, the Building Standards Act, but is not limited to this. The legal provision information records information on the content of the revision in association with the revision time, along with the provisions of the legal provision. The provisions determine the subjects to which the legal provision applies according to the use and size. Furthermore, when the applicable standards become stricter due to legal revisions, warning information is recorded.

[0024] The teacher information storage unit 24 records teacher information used in machine learning. This teacher information is recorded when the teacher information is generated by the learning process. The teacher information includes information on the applicable clause and the applicable area for the floor plan.

[0025] A prediction model for predicting the applicable area of ​​legal provisions is recorded in the learning result storage unit 25. The prediction model is recorded when a learning process is performed. This prediction model is a prediction model that takes a floor plan as input and outputs the applicable area of ​​legal provisions.

[0026] (Legal Provisions Application Processing) Next, the legal provision application process will be described with reference to Figures 3 to 6. This legal provision application process is made up of a learning process (Figure 3(a)) and a prediction process (Figure 3(b)).

[0027] (Learning process) The learning process will be described with reference to FIG. First, the control unit 21 of the management device 20 executes a process of identifying building information (step S11). Specifically, the information acquisition unit 211 of the control unit 21 acquires building information specified in the user terminal 10. Then, the information acquisition unit 211 records the building information in the building information storage unit 22. For example, assume that a building drawing 500 is used as shown in FIG.

[0028] Next, the control unit 21 of the management device 20 executes a process for generating a legal provision application list (step S12). Specifically, the analysis unit 212 of the control unit 21 identifies the applicable legal provision information in the legal provision information storage unit 23 using the construction year (construction time) of the building summary information. Furthermore, the analysis unit 212 identifies the applicable legal provision (article) from the purpose, size, etc. of the building summary information using the identified legal provision information. Then, the analysis unit 212 generates a legal provision application list that displays a list of the identified articles.

[0029] Next, the control unit 21 of the management device 20 executes a drawing acquisition process (step S13). Specifically, the analysis unit 212 of the control unit 21 acquires the building drawing of the construction year (construction time) from the building information storage unit 22.

[0030] Next, the control unit 21 of the management device 20 executes a process of identifying the legal provision application area in association with the construction time (step S14). Specifically, the analysis unit 212 of the control unit 21 outputs the legal provision application list and the building plan to the user terminal 10. The person in charge uses the user terminal 10 to specify the legal provision application area. In this case, the analysis unit 212 marks the designated location. Then, the analysis unit 212 records the marked building plan in the teacher information storage unit 24 in association with the applicable legal provision.

[0031] 5, markers (thick lines, diagonal lines) indicating legal provision application areas 501, 502 designated by the user are added to a building drawing 510. Furthermore, the applicable legal provisions are associated with the legal provision application areas 501, 502, respectively, and recorded in the teacher information storage unit 24.

[0032] Next, the control unit 21 of the management device 20 executes a machine learning process (step S15). Specifically, the learning unit 213 of the control unit 21 generates a prediction model that predicts the legal provision application area using the building plans recorded in the teacher information storage unit 24. This process is executed when a predetermined amount or more of teacher information is accumulated in the teacher information storage unit 24. Then, the learning unit 213 records the generated prediction model in the learning result storage unit 25.

[0033] (Prediction processing) The prediction process will be described with reference to FIG. First, the control unit 21 of the management device 20 executes a process for acquiring a repair work drawing (step S21). Specifically, the information acquisition unit 211 of the control unit 21 acquires the building information specified in the user terminal 10 and the repair work drawing as the evaluation target building image information. Here, it is assumed that the building drawing 500 (FIG. 4) of an existing building is remodeled.

[0034] Next, the control unit 21 of the management device 20 executes a process for identifying the legal provision application area (step S22). Specifically, the prediction unit 214 of the control unit 21 applies the repair work drawing to the prediction model. In this case, the prediction unit 214 predicts the legal provision application area and the applicable legal provision in the repair work drawing. For example, the prediction unit 214 outputs a heat map representing the likelihood of the applicable legal provision in the repair work drawing as the legal provision application area.

[0035] Next, the control unit 21 of the management device 20 executes a process of identifying the construction time for each legal provision application area (step S23). Specifically, the prediction unit 214 of the control unit 21 identifies the construction time for each identified legal provision application area by using the building information acquired from the user terminal 10.

[0036] Next, the control unit 21 of the management device 20 executes a process of identifying the applicable law for each legal provision application area (step S24). Specifically, the prediction unit 214 of the control unit 21 uses the legal provision information storage unit 23 to identify the legal provision that is applied according to the construction time for each legal provision application area.

[0037] Next, the control unit 21 of the management device 20 executes a display process of the revision history for each legal provision application area (step S25). Specifically, the prediction unit 214 of the control unit 21 displays, on the display device H13 of the user terminal 10, legal application information for the legal provisions that are applied for each legal provision provision area identified in the renovation work drawing. Furthermore, the prediction unit 214 searches the legal amendment information for the applicable legal provisions in the legal provision information storage unit 23. Then, when the prediction unit 214 identifies the legal amendment information, it displays the legal application information including the amendment history information.

[0038] 6, a confirmation screen 520 is displayed on the display device H13 of the user terminal 10. On this confirmation screen 520, in addition to the legal provision application areas 501 and 502, new legal provision application areas 521, 522, and 523 are detected in the building plan 500. Then, legal provision application information 531 is displayed for the legal provision application areas 501, 502, and 521 to 523. In this case, if there is a legal revision history, a link 532 is included in the legal provision application information 531.

[0039] When the link 532 is selected, the prediction unit 214 outputs a legal amendment history display 540 acquired from the legal provision information storage unit 23. Here, when the standards have become stricter due to legal amendment and warning information has been recorded, the prediction unit 214 includes a warning display 541 so that the display can be distinguished from other displays.

[0040] (Action of this embodiment) A predictive model is used that outputs the legal provision applicability area, so the applicable legal provisions are displayed using building information as input.

[0041] (Effects of this embodiment) (1) In this embodiment, the control unit 21 of the management device 20 executes a process of identifying building information (step S11), thereby making it possible to acquire building information for creating teacher information.

[0042] (2) In this embodiment, the control unit 21 of the management device 20 executes a process of generating a legal provision application list (step S12). This makes it possible to identify the legal provisions that are applied according to the construction year using the building information.

[0043] (3) In this embodiment, the control unit 21 of the management device 20 executes a process of acquiring drawings (step S13) and a process of identifying the legal provision application area in association with the construction time (step S14). This makes it possible to create teaching information to be used in machine learning from building images.

[0044] (4) In this embodiment, the control unit 21 of the management device 20 executes a machine learning process (step S15), which makes it possible to generate a prediction model that predicts the legal provision application area using the building plan.

[0045] (5) In this embodiment, the control unit 21 of the management device 20 executes a process for acquiring a repair work drawing (step S21). This makes it possible to acquire a building image that is the prediction target. (6) In this embodiment, the control unit 21 of the management device 20 executes a process of identifying the legal provision application area (step S22). This makes it possible to predict the legal provision application area using the building plan.

[0046] (7) In this embodiment, the control unit 21 of the management device 20 executes a process of identifying the implementation time for each legal provision application area (step S23) and a process of identifying the applicable law for each legal provision application area (step S24). This makes it possible to identify the applicable legal provision according to the implementation time even if the legal provision is revised.

[0047] (8) In this embodiment, the control unit 21 of the management device 20 executes a process of displaying the revision history for each legal provision applicable area (step S25). This allows compliance with legal provisions by taking into account the revision history.

[0048] This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction. In the above embodiment, the user terminal 10 and the management device 20 are used, but the hardware configuration is not limited to these.

[0049] In the above embodiment, the control unit 21 of the management device 20 executes a process of identifying building information (step S11). Here, architectural drawings are used as building images, but architectural information is not limited to drawings. For example, element models (three-dimensional models) created using BIM may be used. In this case, the applicable legal provisions may be identified using attribute information included in the element models. In the above embodiment, the control unit 21 of the management device 20 executes a process of identifying the legal provision applicable area in association with the construction time (step S14). Here, the person in charge specifies the legal provision applicable area using the user terminal 10. Alternatively, the control unit 21 of the management device 20 may identify the applicable area. In this case, for example, the applicable area is identified using information written on the building plan.

[0050] In the above embodiment, the control unit 21 of the management device 20 executes machine learning processing (step S15). Here, a prediction model may be generated for each legal revision period using training information from before the legal revision period. In this case, the control unit 21 of the management device 20 selects a prediction model according to the construction period of the building to be evaluated, and identifies the legal provision application area. In the above embodiment, the control unit 21 of the management device 20 executes a process for acquiring a repair work drawing (step S21). The application is not limited to a repair work drawing. For example, the application may be applied to a building drawing of a newly constructed building.

[0051] In the above embodiment, the control unit 21 of the management device 20 executes machine learning processing (step S15). Here, a prediction model for predicting the legal provision applicability area is generated using the building plans (building image information) stored in the teacher information storage unit 24 as teacher information. This teacher information includes information on the applicable provisions and the applicable area for the floor plan. The teacher information is not limited to the floor plan including information on the applicable provisions and the applicable area. For example, feature amounts may be used as information indicating the characteristics of the building image as the building image information. Furthermore, the machine learning method is not limited to supervised learning using building image information. For example, a large amount of unlabeled building image information is used to pre-train a predictive model to generate a feature extractor. Then, this feature extractor may be used for transfer learning to extract applicable clauses and applicable areas from the building image information.
