Abstract
Description
Technical Field
[0001] The present disclosure relates to a document management device, a document management method, and a document management program for managing documents related to construction work.
Background Art
[0002] When performing construction work on a building, the construction contractor needs to submit various documents prior to the work. For example, the documents include design drawings, construction plans, construction organization ledger, documents required based on the Building Standards Law (such as building confirmation application, commencement notice, intermediate inspection application, completion inspection application, etc.), and construction completion reports. Technologies for managing such information related to construction work have also been studied (see Patent Document 1). In the technology described in this document, the contents of the application documents submitted and applied during the construction work are registered in the application document database. Then, based on search conditions related to the construction work, extraction status information included in the application documents related to the construction work is extracted from the application document database. When a construction project that requires adjustment of the construction content is specified from the extraction status information, a request for adjustment of the construction content is notified to the devices of each related organization of the specified construction project. At the same time, the adjustment management information in which the information to be adjusted is managed is additionally updated. Then, based on the results of the adjustments implemented by the adjustment request, the adjustment management information is updated.
[0003] In addition, an architectural information integrated management system that enables seamless access to information between 3D CAD data and architectural related information has also been studied (see Patent Document 2). The architectural information integrated management system described in this document includes a storage unit that stores 3D model master data and architectural related information master data including architectural related information, and a display unit that projects and displays an object on a viewport. Then, related architectural related information is extracted based on the object. Next, a menu list of the viewport according to the projection rule selected based on the object is extracted, and the menu list is displayed on the display unit.

[0004] [Patent Document 1] Japanese Patent Publication No. 2003-233646 [Patent Document 2] Japanese Patent Publication No. 2015-38743 [Overview of the project] [Problems that the invention aims to solve]
[0005] When documents are digitized, management is easy. However, in large buildings, construction records are often stored on paper. Furthermore, when buildings are expanded or remodeled, the number of records increases each time, making management time-consuming. [Means for solving the problem]
[0006] A document management device for solving the above problems includes a control unit connected to a user terminal. The control unit acquires document data related to construction work from the user terminal, generates text from the information contained in the document data, tags and structures the text, classifies the document data for each construction activity, checks whether necessary documents for the construction activity are present, and if there are any missing necessary documents in the document data, outputs warning information to the user terminal. [Effects of the Invention]
[0007] According to this disclosure, construction-related documents can be managed efficiently. [Brief explanation of the drawing]

[Figure 3] This is an explanatory diagram of the processing procedure of the embodiment. [Figure 4] This is an explanatory diagram of the output screen of the embodiment. [Figure 5] This is an explanatory diagram of an output screen in a different example. [Figure 6] This is an explanatory diagram of an output screen in a different example. [Modes for carrying out the invention]
[0009] The following describes one embodiment of a document management device, document management method, and document management program using Figures 1 to 4. This embodiment describes a case in which documents used in construction work are reviewed. As shown in Figure 1, the document management device A1 of this embodiment includes user terminals 10 and a management device 20 that are interconnected via a network.
[0010] (Description of hardware configuration) Figure 2 illustrates the hardware configuration of the information processing device H10, which constitutes the user terminal 10 and the management device 20. 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 just one example, and it can be implemented with other hardware.
[0011] Communication device H11 is an interface that establishes a communication path with other devices and performs data transmission and reception. The input device H12 is a device that accepts input of various types of information. The display device H13 is a display or the like that displays various types of 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 storage devices H14 include ROM, RAM, and hard disks.
[0013] Processor H15 controls each process in user terminal 10 and management device 20 by using programs and data stored in storage device H14. Examples of processor H15 include, for example, a CPU, an MPU, and the like. This processor H15 expands a program stored in a ROM or the like to a RAM and executes various processes for each process.
[0014] Processor H15 is not limited to performing software processing for all processes it executes. For example, processor H15 may include a dedicated hardware circuit (for example, an application-specific integrated circuit: ASIC) that performs hardware processing for at least a part of the processes it executes. That is, processor H15 can 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 execute at least a part of various processes [3] A combination thereof, including circuitry The processor includes a CPU and memories such as a RAM and a ROM, and the memories store program codes or instructions configured to cause the CPU to execute processes. The memory, that is, the computer-readable medium, includes any available medium that can be accessed by a general-purpose or dedicated computer.
[0016] (Form Management Device A1) The form management device A1 will be described with reference to FIG. 1. User terminal 10 is a computer terminal used by a user.
[0017] Management device 20 is a computer system that supports the management of forms in construction work. Management device 20 includes a control unit 21, a required form information storage unit 22, and an existing form information storage unit 23.
[0018] The control unit 21 performs the processing described later (including the acquisition stage, recognition stage, management stage, etc.). By executing the processing program for this purpose, the control unit 21 functions as the acquisition unit 211, recognition unit 212, management unit 213, etc.
[0019] The acquisition unit 211 executes a process to acquire information about the building. In this embodiment, it acquires scanned data (images) of forms (paper media) used in the construction work. The recognition unit 212 performs character recognition processing (OCR processing) to recognize characters contained in the image. This character recognition processing uses AI-OCR technology that predicts the attributes of the acquired characters and structures them by tagging them in association with the characters. Management Unit 213 executes the process of managing the forms necessary for construction work.
[0020] The required document information storage unit 22 stores required document management information for documents necessary for building construction work. This required document management information is recorded when the types of documents required for the construction work are registered. The required document management information includes information about the types of documents required for each type of construction work.
[0021] Depending on the type of construction work, such as new construction, renovation, or extension, the necessary documents recorded are those specified by the Building Standards Act, the Construction Industry Act, the Workers' Accident Compensation Insurance Act, etc. For example, necessary documents include building permit applications, permits, and inspection certificates. Other necessary documents include plan change documents, construction contracts, construction ledgers, construction management ledgers, construction system diagrams, subcontracting notices, documents that must be provided to the client, workers' accident insurance-related documents, and safety and health-related documents.
[0022] The existing document information storage unit 23 stores existing document management information related to documents used in the construction of a building. This existing document management information is recorded when documents used in the construction work are acquired. This existing document management information includes information on the building identifier, image, type of work, type of document, construction area, construction details, and drawings.
[0023] A building identifier is an identifier used to identify each building. The image is image data generated by scanning paper documents. The construction type is a category that specifies the type of construction activity (new construction, extension, renovation, etc.).
[0024] The document type is the type of document determined based on this image. The construction area indicates the scope of construction work carried out within this building.
[0025] The construction details document contains information indicating the nature of the construction work performed on this building. This includes information such as the date the document was created, the construction period, the creator, and the details of the work. For example, a building permit application includes information about the applicant, the building, and the site. The drawings are those of this building. For example, the documents attached to the building plan summary of the building permit application (site plan, floor plan, elevations, sections, structural drawings, equipment drawings, etc.) can be used.
[0026] (Document management processing) Next, we will explain the document management process using Figure 3.
[0027] First, the control unit 21 of the management device 20 executes the process of acquiring the report file (step S11). Specifically, the acquisition unit 211 of the control unit 21 displays an upload screen on the user terminal 10. This upload screen includes a building information input field and a report input field. In this case, the user terminal 10 enters the building identifier in the building information input field. Then, the user terminal 10 scans the reports stored on paper regarding the construction work. Here, we assume a case where scanned images (report data) of reports related to the building are compiled into a report file. Then, the report file containing multiple scanned images is entered into the report input field. In this case, the acquisition unit 211 of the control unit 21 acquires the building identifier and the report file from the user terminal 10. Then, the acquisition unit 211 records the existing report management information, including the images contained in the report file, in the existing report information storage unit 23, associating it with the building identifier.
[0028] Next, the control unit 21 of the management device 20 repeats the following process for each document. Here, the control unit 21 of the management device 20 performs character recognition processing (step S12). Specifically, the recognition unit 212 of the control unit 21 generates text from the characters contained in the image through character recognition processing. Furthermore, the recognition unit 212 recognizes images such as charts and graphs contained in the form and generates text from the content that the images represent.
[0029] Next, the control unit 21 of the management device 20 performs structuring processing (step S13). Specifically, the recognition unit 212 of the control unit 21 predicts the attributes (items) and item values of the text based on the content and location of the text it has read. For example, it predicts the type of construction work, the type of report, the construction area, and the details of the construction work. This performs structuring (categorization) to organize the components included in the construction work and the relationships between those components. The recognition unit 212 then records the read items and item values in the existing report information storage unit 23. Repeat the above process for all reports until it is complete.
[0030] Next, the control unit 21 of the management device 20 performs grouping processing for each construction activity (step S14). Specifically, the management unit 213 of the control unit 21 classifies and groups the documents according to the construction activities identified based on the images. In this case, attributes included in the building management information are used to generate a set of documents that are included in the same construction activity. For example, the same construction activity performed on the same day and in the same area is grouped together based on the construction date and construction area of the construction activity.
[0031] Next, the control unit 21 of the management device 20 performs a necessary document verification process for each construction activity (step S15). Specifically, the management unit 213 of the control unit 21 identifies the construction activities performed on the building that are recorded in the existing document information storage unit 23. Then, the management unit 213 identifies the type of document required for the construction activity identified using the documents from the necessary document information storage unit 22.
[0032] Next, the control unit 21 of the management device 20 performs a determination process to determine whether the requirements are met (step S16). Specifically, the management unit 213 of the control unit 21 checks for the existence of required forms by matching the form type of the required forms with the existing forms for each group of construction activities. If the existing forms for all required forms are registered in the existing form information storage unit 23, the requirements are determined to be met.
[0033] On the other hand, if it is determined that there are missing required documents among the existing documents and that the requirements are not met (if the answer is "NO" in step S16), the control unit 21 of the management device 20 performs a warning process (step S17). Specifically, the management unit 213 of the control unit 21 outputs warning information to the user terminal 10. This warning information includes information that identifies the missing required documents for the type of construction work.
[0034] If the condition is met (i.e., "YES" in step S16), the control unit 21 of the management device 20 skips the warning process (step S17). Next, the control unit 21 of the management device 20 performs the association process with the drawings (step S18). Specifically, the management unit 213 of the control unit 21 obtains the floor plan (overall view) from the existing document information storage unit 23 and outputs the building drawing to the user terminal 10. In this building drawing, the existing document management information in the existing document information storage unit 23 is set to be selectable for each construction area. Then, for the construction area specified on the user terminal 10, the documents related to this area are output for each construction activity.
[0035] As shown in Figure 4, the building drawing 510 on the output screen 500 displays existing reports for the construction work that has been carried out. For construction work in area 520, report icons 521 to 526 are displayed. If icon 523 is selected, the report image 523P is output. In area 530, the report for icon 535 is displayed in a color scheme (e.g., gray) to indicate that there are missing reports. This allows for the identification of the construction area (area 530) corresponding to the construction activity for which warning information has been output. If multiple construction works have been carried out in the same area, the report is displayed by specifying the type of work and the construction period.
[0036] (Operation of this embodiment) Paper documents used in construction work are structured using character recognition, allowing them to be associated with construction activities and work areas.
[0037] (Effects of this embodiment) (1) In this embodiment, the control unit 21 of the management device 20 executes the process of acquiring the form file (step S11). This makes it possible to manage paper forms electronically.
[0038] (2) In this embodiment, the control unit 21 of the management device 20 performs character recognition processing (step S12) and structuring processing (step S13). This makes it possible to manage electronic documents in a structured (tagged) manner according to their content.
[0039] (3) In this embodiment, the control unit 21 of the management device 20 performs grouping processing for each construction activity (step S14). This makes it possible to manage the forms that are managed for each building according to the construction activity.
[0040] (4) In this embodiment, the control unit 21 of the management device 20 performs a necessary form verification process for each construction activity (step S15). If it is determined that there are missing necessary forms among the existing forms and that the requirements are not met (if the result is "NO" in step S16), the control unit 21 of the management device 20 performs a warning process (step S17). This enables accurate management of necessary forms.
[0041] (5) In this embodiment, the control unit 21 of the management device 20 performs association processing with drawings (step S18). This makes it possible to efficiently manage the documents being managed according to the area of the building.
[0042] This embodiment can be implemented with the following modifications. This embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically. • In the above embodiment, a user terminal 10 and a management device 20 were used, but the hardware configuration is not limited to these.
[0043] In the above embodiment, the control unit 21 of the management device 20 performs association processing with drawings (step S18). Here, architectural drawings are used as building images, but the architectural information is not limited to drawings. For example, element models (3D models) created using BIM may be used. In this case, attribute information contained in the element model is used to identify the managed documents.
[0044] As shown in Figure 5, the output screen 600 displays the 3D model 610 of the building generated by BIM, and associates existing documents with each area 620 and 630 of the 3D model 610. Then, it outputs the documents related to the areas 620 and 630 specified in the 3D model 610.
[0045] In the above embodiment, the control unit 21 of the management device 20 executes the process of acquiring the report file (step S11). Here, the building identifier is acquired from the user terminal 10. Alternatively, the building identifier may be acquired from an image of an existing report. In this case, even if there are multiple buildings, the report files may be uploaded all at once.
[0046] In the above embodiment, the control unit 21 of the management device 20 performs the association process with drawings (step S18). The display method is not limited to association with drawings. For example, a table may be output that lists the documents according to the type of construction in order of construction period. Figure 6 shows Table 700, which lists the creation dates of existing records for each construction activity.
[0047] Next, the technical concepts that can be understood from the above embodiments and alternative examples are described below.
