[0002] Conventionally, a management system for managing the work of workers at a construction site has been put into practical use. As an example of the technology for realizing such a management system, for example, Patent Document 1 has been proposed.

[0003] Patent Document 1 discloses that the entry / exit history of a worker is stored in association with the worker, a viewing template or a report template is read from a viewing / report template storage unit, written into the viewing template or the report template based on the registered entry / exit history, a viewing screen (report) is transmitted to the viewing source (request source), and the entry / exit history of the recorded entry / exit personnel can be viewed or created as a report.

Prior Art Documents

[0007] To solve the above problems, the present invention provides a business management system for managing the risk prediction activities of workers at construction sites, The aforementioned business management system comprises a database, a candidate identification unit, and a display processing unit. The aforementioned database stores site information including the workers scheduled to work at the construction site, and entry and exit history information regarding the workers' entry and exit from the construction site. The candidate identification unit identifies candidate participants for the hazard prediction activity on the predetermined construction day based on the site information and entry / exit history information on the predetermined construction day. The display processing unit processes the list of candidate participants to display.

[0008] Furthermore, the present invention relates to a business management method using a business management system for managing the risk prediction activities of workers at construction sites, The aforementioned business management system is A process for storing site information including the workers scheduled to work at the construction site, and entry / exit history information regarding the workers' entry and exit from the construction site, A process to identify potential participants for the hazard prediction activity on a predetermined construction day, based on the aforementioned site information and entry / exit history information on that predetermined construction day, The process of displaying a list of the aforementioned candidate participants, Execute this.

[0009] Furthermore, the present invention relates to a business management program for managing hazard prediction activities of workers at construction sites, wherein the business management program uses a computer as a database, a candidate identification unit, and a display processing unit. The aforementioned database stores site information including the workers scheduled to work at the construction site, and entry and exit history information regarding the workers' entry and exit from the construction site. The candidate identification unit identifies candidate participants for the hazard prediction activity on the predetermined construction day based on the site information and entry / exit history information on the predetermined construction day. The display processing unit processes the list of candidate participants to display.

[0010] In a preferred embodiment of the present invention, the database stores activity participation history information for each construction site, indicating the participation history of workers who participated in the hazard prediction activity prior to the predetermined construction date as the scheduled workers, The candidate identification unit receives the designation of the construction site where the hazard prediction activity will be carried out from the work reporter, and identifies the candidate participants for the hazard prediction activity at the construction site on the specified construction day based on the construction site, the planned workers based on the activity participation history information, and the entry and exit history information.

[0011] This configuration allows for the management of hazard prediction activities. In particular, by displaying workers who may have participated in hazard prediction activities as potential participants, it is possible to register participants in hazard prediction activities easily and efficiently. Furthermore, it prevents the omission of registered candidates who may have participated in hazard prediction activities.

[0012] In a preferred embodiment of the present invention, the business management system further comprises an image acquisition unit and an activity registration unit. The image acquisition unit acquires participant images of workers who participated in the hazard prediction activity at the construction site on the predetermined construction day, as activity participants. The activity registration unit accepts the designation of activity participants who actually participated in the hazard prediction activity on the predetermined construction date from among the candidate participants, and registers the activity participants and their images in the database.

[0013] By using this configuration, the authenticity of the registered data can be ensured by linking images of the workers who actually performed the hazard prediction activities to the hazard prediction activity personnel managed in the data.

[0014] In a preferred embodiment of the present invention, the candidate identification unit compares the entry and exit history information for a predetermined construction date at the construction site with the entry and exit history information prior to the predetermined construction date to identify as candidate participants workers who participated in the hazard prediction activity at the construction site prior to the predetermined construction date and whose entry and exit history information for the predetermined construction date and the entry and exit history information prior to the predetermined date are registered.

[0015] With this configuration, if there are workers whose entry and exit history has been registered in the past but whose entry and exit history to the construction site has not been registered for the current construction work, it can be assumed that such workers are not participating in the current construction work, and such workers can be excluded from being displayed as potential participants in hazard prediction activities. This makes it easier to narrow down the participants in hazard prediction activities by not displaying workers who are unlikely to have participated in hazard prediction activities.

[0016] In a preferred embodiment of the present invention, the business management system further comprises a notification unit, The aforementioned site information includes the details of the construction work at the construction site, The aforementioned database stores activity qualification information regarding the qualifications for the aforementioned hazard prediction activities for each worker, The notification unit receives the candidate participants selected from the work reporter as activity participants who participated in the hazard prediction activity at the construction site, and issues a notification if none of the selected candidate participants have activity qualification information linked to the construction work content at the construction site.

[0017] This configuration prevents situations where hazard prediction activities are completed without qualified workers present to conduct them.

[0018] In a preferred embodiment of the present invention, the business management system further comprises an image acquisition unit and an activity registration unit. The aforementioned database stores facial information for each worker, The image acquisition unit acquires an image of an operator who participated in the danger prediction activity at the construction site on the predetermined construction date, Based on the face information and the image of the operator, the activity registration unit registers the operator included in the image of the operator as an activity participant.

[0019] With such a configuration, in addition to displaying candidate participants, by registering activity participants based on the captured images of the operators, it is possible to prevent omission of registration of participants in the danger prediction activity.

Effect of the Invention

[0020] According to the present invention, it is possible to provide a novel technology for managing danger prediction activities at a construction site.

[Modes for carrying out the invention]

[0022] Further details will be provided below with reference to the attached drawings. The drawings show preferred embodiments. However, many different forms are possible and the invention is not limited to those described herein.

[0023] For example, in this embodiment, the configuration and operation of the business management system will be described, but similar effects can be achieved by the execution method (steps), device, computer program, etc. The program in this embodiment may be provided as a non-transient recording medium that can be read by a computer, or it may be provided so that it can be downloaded from an external server.

[0024] Furthermore, in this embodiment, "part" may also include, for example, hardware resources implemented by circuits in a broad sense, and software information processing that can be specifically realized by these hardware resources.

[0025] In this embodiment, "information" can be represented, for example, by the physical value of a signal representing voltage or current, the high or low value of a signal as a set of binary bits consisting of 0s or 1s, or by a quantum superposition (so-called qubit), and communication and calculations can be performed on a circuit in a broad sense.

[0026] In a broad sense, a circuit is a circuit realized by appropriately combining circuits, circuits (including processors and memory). That is, it includes CPUs (Central Processing Units), GPUs (Graphics Processing Units), LSIs (Large Scale Integration), ASICs (Application Specific Integrated Circuits), FPGAs (Field-Programmable Gate Arrays), etc.

[0027] <1. Overview of the Invention> This invention relates to a system for managing hazard prediction activities performed by workers at construction sites. Construction sites have a wide variety of tasks and a multi-layered subcontracting structure, resulting in a vast number of regulations that must be followed compared to other industries, including the Construction Industry Act, the Industrial Safety and Health Act, and guidelines from various ministries and agencies. In particular, during the "construction" phase, while it is necessary to balance the five major management aspects (quality, schedule, cost, safety, and environment) with legal compliance, it is also necessary to create deliverables that record and report on the execution of those regulations. Therefore, there is a need for a system that supports reliable management while reducing the burden on the site.

[0028] However, standardization has not progressed, particularly with regard to deliverables, due to regional differences (such as the jurisdiction of the labor standards office), client specifications, and company-specific approaches. As a result, the format and details of the items included differ, leading to a burden on the workforce. This is the biggest obstacle to the paperless nature of these tasks, and the present invention aims to solve this problem. In particular, the present invention aims to make hazard prediction activities (so-called on-site KY activities) conducted before work begins at construction sites paperless.

[0029] <2. System Configuration> Figure 1 is a block diagram showing the system configuration according to one embodiment of the present invention. As shown in Figure 1, the business management system 0 comprises a business management device 1, a worker terminal device 3, an administrator terminal device 4, and an access control device 5, and is configured to communicate via a network NW. In this embodiment, each administrator (head office or branch of the main contractor) is in charge of multiple construction sites, and each construction site is assigned multiple subcontractors that partner with the administrator. Each subcontractor assigns a foreman and workers for each construction task it undertakes (see Figure 2). Hereinafter, foremen and workers will be collectively referred to as workers.

[0030] Furthermore, the business management system 0 may appropriately share the processing described later between the business management device 1, the worker terminal device 3, and the administrator terminal device 4, and is not limited to the processing sharing described later.

[0031] The business management device 1 can utilize general-purpose server computers or personal computers, and may be composed of multiple computers that are capable of sending and receiving information via a network NW or another network.

[0032] The worker terminal device 3 is a terminal device used by workers performing work at a construction site to input data related to hazard prediction activities, and can utilize personal computers, smartphones, tablet devices, wearable devices, etc.

[0033] The administrator terminal device 4 is a terminal used by administrators of the main contractor or other similar companies to input master data related to hazard prediction activities and display activity information, and can utilize personal computers, smartphones, tablet devices, wearable devices, etc.

[0034] The access control device 5 is installed at each construction site and acquires information that uniquely identifies each worker (worker identification information: for example, facial image or biometric authentication information) and registers it in the database 2 described later. For example, a well-known authentication device can be used as the access control device 5.

[0035] In this embodiment, the network NW is an IP (Internet Protocol) network, but there are no restrictions on the type of communication protocol, nor on the type or size of the network.

[0036] <3. Hardware Configuration> Figure 3 is a block diagram showing the hardware configuration of the system according to the present invention. As shown in Figure 3(a), the server 10 (business management device 1) comprises a control unit 101, a storage unit 102, and a communication unit 103.

[0039] The communication unit 103 has a communication interface device for connecting to the network, and performs communication control with the network NW to provide inputs necessary for operating the business management device 1, as well as outputs related to the operation results.

[0040] Figure 3(b) shows an example of the hardware configuration of terminal device 9 (worker terminal device 3 and administrator terminal device 4 in Figure 1). Terminal device 9 comprises a control unit 91, a storage unit 92, a communication unit 93, an input unit 94, and a display unit 95 as its hardware configuration.

[0041] The control unit 91 of the terminal device 9 includes one or more processors, such as a CPU, capable of executing instruction sets, and controls the entire operation process of the terminal device 9 by executing the OS and other applications. The memory unit 92 of the terminal device 9 has volatile memory such as RAM that can store instruction sets, and non-volatile recording media such as HDDs or SSDs that can store the OS, etc. The communication unit 93 of the terminal device 9 has a communication interface device for connecting to a network, and performs communication control with the network NW to input and output information. The input unit 94 has input devices capable of input processing, such as a keyboard, a touch panel, and a camera for capturing images of the worker's face. The display unit 95 has a display device capable of display processing, such as a display.

[0042] <4. Functional Configuration> Figure 4 is a block diagram showing the functional configuration of the system in the present invention. As shown in Figure 4, the business management device 1 comprises a work schedule registration unit 11, a master registration unit 12, an entry / exit management unit 13, a candidate identification unit 14, an image acquisition unit 15, an activity registration unit 16, a notification unit 17, a display processing unit 18, and a database 2. These represent information processing by software (stored in the storage unit 102) that is concretely realized by hardware (control unit 101, etc.).

[0043] In this embodiment, the system is a so-called server-client type, where the client receives the processing results performed by the business management device 1 (server) in response to requests from the worker terminal device 3 and the administrator terminal device 4 (client). Alternatively, it may be a so-called standalone type, where the business management program is launched on the client terminal. In this case, the worker terminal device 3 and the administrator terminal device 4 may comprise some or all of the functional components (parts) of the business management device 1. For example, the worker terminal device 3 may comprise a work schedule registration unit 11, a candidate identification unit 14, an image acquisition unit 15, an activity registration unit 16, a notification unit 17, and a display processing unit 18, the administrator terminal device 4 may comprise a master registration unit 12, an entry / exit management unit 13, and a display processing unit 18, and the business management device 1 may be a cloud storage that records and manages the acquired activity information and activity confirmation item master described later.

[0044] <4.1. Work Schedule Registration Section 11> The work schedule registration unit 11 registers work information related to construction work. The work schedule registration unit 11 acquires work schedule information, including the cooperating companies that will perform construction work at the construction site, the details of the work to be performed, and the work time, as well as worker information, indicating which workers from the cooperating companies will be in charge of the construction site, and registers the work information, including the work schedule information and worker information, in the database 2.

[0045] <4.2.

[0047] <4.4.Candidate identification part 14> The candidate identification unit 14 identifies candidate participants for the hazard prediction activity. Based on the site information and entry / exit history information described later for the specified construction day, the candidate identification unit 14 identifies candidate participants for the hazard prediction activity on the specified construction day.

[0048] <4.5. Image Acquisition Unit 15> The image acquisition unit 15 acquires participant images of workers who participated in the hazard prediction activity. The image acquisition unit 15 acquires participant images via the camera of the worker terminal device 3 or via the storage unit 92 of the worker terminal device 3.

[0049] <4.6. Activity Registration Section 16> The activity registration unit 16 registers activity information related to hazard prediction activities. The activity registration unit 16 acquires activity result data related to hazard prediction activities, activity result information including workers who actually participated in the hazard prediction activities (hereinafter referred to as "activity participants"), and activity verification information linked to the activity participants and their images, and registers the activity information, including the activity result information and activity verification information, in the database 2.

[0050] Furthermore, the activity registration unit 16 registers activity result information based on the authentication results of the workers included in the activity participant image. Based on the activity participant image and the face information (face image and / or face video) stored in the database 2 for each worker, the activity registration unit 16 registers the workers included in the activity participant as activity participants in the activity result information.

[0051] <4.7. Notification section 17> The notification unit 17 issues a notification based on predetermined conditions. The notification unit 17 issues a notification using the qualification information of the activity participants as predetermined conditions. It accepts candidate participants selected from the work reporters as activity participants, and issues a notification if, as predetermined conditions, none of the selected candidate participants have activity qualification information linked to the construction work content at the construction site.

[0052] <4.8. Display Processing Unit 18> The display processing unit 18 processes the display screens of the worker terminal device 3 and the administrator terminal device 4. Specific display screens will be described later.

[0053] In this embodiment, the display process refers to the process in which the display processing unit 18 executes a process to generate information necessary for display, transmits the generated information to the display unit 95 of the terminal device 9, and the display unit 95 displays the generated information. Alternatively, the display processing unit 18 may transmit a processing command to the terminal device 9 to generate information necessary for display, causing the terminal device 9 to generate the information necessary for display and to display the generated information on the display unit 95.

[0054] <4.9. Database 2> Figures 5-6 show an example of the information stored in Database 2 in this embodiment. Database 2 stores project information related to the construction work to be carried out, construction system information related to the construction system in the construction work to be carried out, general contractor information related to the general contractor, cooperating company information related to cooperating companies, etc., worker information related to workers belonging to the general contractor and cooperating companies, work information registered by the work schedule registration unit 11, entry and exit history information registered by the entry and exit management unit 13, activity qualification information indicating the qualifications required for carrying out hazard prediction activities, activity confirmation item master registered by the master registration unit 12, and activity information (activity result information (activity participation history information) and activity certification information) registered by the activity registration unit 16. In this embodiment, site information related to the construction site includes work schedule information, worker schedule information, and project information. Activity qualification information may also include qualifications required according to the construction content for carrying out hazard prediction activities. Furthermore, worker identification information included in worker information may be information that uniquely identifies a worker who has been registered in advance, or it may be facial information registered based on the worker image described later. Some or all of these may be stored in the memory unit 102, or some of them may be stored in another database, etc.

[0055] <5. Sequence diagram in this embodiment> The following describes the business management system 0 and the processing content of each functional component, with reference to Figures 7 to 11. Figure 7 is a sequence diagram showing the process from the day before construction work begins, when the general contractor and cooperating companies responsible for construction work at each construction site cooperate to register the work plan (work schedule information) for the following day, to the implementation of hazard prediction activities and construction work at the construction site according to the work plan, and to the submission of a work completion report for the day. The processing related to the business management method in this embodiment is broadly divided into pre-processing (A), entry / exit registration processing (B), activity information registration processing (C), and activity information display processing (D).

[0056] <5.1. Pre-processing (A)> In pre-processing (A), multiple foremen (workers) belonging to each subcontractor assigned to a construction site hold a coordination meeting regarding the construction work for the following day, register the results of the meeting as work information, and the general contractor (manager) registers the activity confirmation items for the hazard prediction activity for the following day based on this work information.

[0057] <5.1.1. Registration of work information> First, in steps SA01 to SA03 (hereinafter, "step SX" will simply be referred to as "SX"), work information is registered.

[0058] In SA01, the worker terminal device 3 receives work information input from the worker. In this embodiment, each worker at the construction site operates their own worker terminal device 3 to input work information (see Figures 6(a) and 6(b)) including the work content for the next day's construction work, the work schedule (start time, end time), and the person in charge (cooperating company and workers for each cooperating company).

[0059] In SA02, the worker terminal device 3 transmits the work information entered in SA01 to the work management device 1, and in SA03, the work schedule registration unit 11 registers the work information in the database 2 for each construction site.

[0060] <5.1.2. Registration of Activity Confirmation Items Master> Next, in SA04 to SA08, the activity confirmation item master is registered. In this embodiment, the work information registered in SA03 is referenced to register the activity confirmation item master.

[0061] In SA04, the administrator terminal device 4 receives input from the administrator regarding a request to display work information and transmits the display request to the business management device 1. In SA05, the display processing unit 18 processes the work information for display. In this embodiment, in addition to the request to display work information, the administrator terminal device 4 transmits administrator identification information (such as the prime contractor's company ID) to the business management device 1. The display processing unit 18 refers to the construction system information, identifies the work information for the project corresponding to the received administrator identification information, and processes the work information for display. If multiple work information items are to be displayed, the display processing unit 18 accepts input to select one desired work information item and processes the work information for display.

[0062] In SA06, the administrator terminal device 4 receives input from the activity confirmation item master. In this embodiment, the display processing unit 18 displays the work information to be displayed in SA05, and also displays the input section for the activity confirmation item data (category and content of the confirmation item), which is the data to be registered as the activity confirmation item master, on the same screen. The administrator terminal device 4 then receives input of the activity confirmation item data from the administrator via this input section.

[0063] Specifically, depending on the work schedule to be carried out in a day (for example, work schedules such as bringing in heavy machinery), the categories (for example, safety confirmation items, work completion report, etc.) and content (for example, ground conditions, obstacle checks, etc.) of the hazard prediction activity confirmation items to be carried out on that day must be set, and the administrator terminal device 4 accepts input of activity confirmation item data for each work item in the work information.

[0064] More specifically, a work content confirmation item correspondence table showing corresponding activity confirmation item data for each work content is pre-registered in database 2. The display processing unit 18 refers to the work content confirmation item correspondence table and displays the category and content of the activity confirmation item data corresponding to the work content of the work information selected and entered in SA04 in a selection input format (pull-down menu, etc.). The administrator terminal device 4 accepts the selection input of the displayed activity confirmation item data from the administrator. Note that input of both the category and content of the confirmation item data for each work content may be accepted, or the category of the confirmation item may be set in advance, and input of only the content of the confirmation item may be accepted.

[0065] In SA07, the administrator terminal device 4 transmits the activity confirmation item data entered in SA06, and in SA08, the master registration unit 12 registers the activity confirmation item master in the database 2. In this embodiment, the master registration unit 12 acquires the activity confirmation items transmitted in SA07 and registers an activity confirmation item master in which the work information selected and entered in SA04 is linked to the activity confirmation items.

[0066] In a preferred embodiment of the present invention, the master registration unit 12 receives administrator identification information (such as a branch ID) in addition to the activity confirmation item data in SA07, and registers an activity confirmation item master to which the administrator identification information is further linked.

[0067] In this embodiment, the administrator sets the activity confirmation item master while referring to the registered work information, but the activity confirmation item master may also be set automatically based on the work information. Specifically, the master registration unit 12 compares the work information registered in SA03 with the work content confirmation item correspondence table and registers an activity confirmation item master having activity confirmation item data corresponding to the work information.

[0068] In another preferred embodiment of the present invention, the work content confirmation item correspondence table may be registered by referring to past master registration history. Specifically, the master registration unit 12 registers the combination of activity confirmation item data and work information registered in the activity confirmation item master as a work content confirmation item correspondence table.

[0069] As described above, the pre-processing (A) is completed when the processes SA01 to SA08 are executed. In this embodiment, the activity confirmation item master is set according to the work information registered in SA03, but an activity confirmation item master that can be used universally regardless of the work information may also be set. In this case, the processes related to the display of work information (SA04 to SA05) are not executed, and only the processes from input to registration of the activity confirmation item master (SA06 to SA08) are executed.

[0070] <5.2. Admission / Exit Registration Process (B)> Next, in the entry / exit registration process (B), the process is executed to register the entry and exit history of workers entering the construction site, based on the work information registered the previous day.

[0071] <5.2.1. Registration of Entry / Exit History Information> In SB01 to SB03, entry and exit history information is registered.

[0072] In SB01, the access control device 5 acquires worker identification information of workers entering the construction site. In this embodiment, the access control device 5 acquires worker identification information via a device that acquires worker identification information. For example, the access control device 5 acquires a worker's facial image as worker identification information via a camera. It also acquires a worker's fingerprint pattern as worker identification information via a fingerprint sensor. Furthermore, it acquires a worker's ID as worker identification information via a keyboard.

[0073] In SB02, the access control device 5 transmits the worker identification information acquired in SB01 and information identifying the construction site where the access control device 5 is installed (such as project ID or construction site location) to the business management device 1. In SB03, the access control unit 13 registers the access history information linked to the worker identification information, the time the worker identification information was acquired, and the project ID into the database 2.

[0074] The entry / exit registration process (B) is completed when the processes SB01 to SB03 are executed. As a result, entry / exit history information is registered for each construction site (project). The entry / exit management device 5 may transmit the acquired worker identification information to the business management device 1 each time it acquires the worker identification information, or it may transmit it periodically at predetermined intervals.

[0075] <5.3. Activity Information Registration Process (C)> Next, in the activity information registration process (C), the activity confirmation item data registered the previous day is displayed on the worker terminal device 3, and the process is executed until the worker inputs the activity results of the hazard prediction activity and registers the activity information (see Figure 8).

[0076] <5.3.1. Receiving Activity Result Data> Activity result data can be entered in SC01 to SC06.

[0077] In SC01, the worker terminal device 3 sends a request to the business management device 1 to display the activity result input screen, and in SC02, the display processing unit 18 processes the activity result input screen. In this embodiment, the worker terminal device 3 receives information from the worker to identify the project (project name, project ID, construction site name, etc.), and sends the project identification information to the business management device 1 in addition to the request to display the activity result input screen. The display processing unit 18 processes the activity result input screen, which displays one or more work contents corresponding to the project ID in a selectable input format.

[0078] Figure 9 shows an example of the screen that is initially displayed in response to a request to display the activity results input screen. In the example shown, multiple work information (work details) associated with the project received from the worker terminal device 3 are displayed, and the screen is displayed in a way that allows for the selection input of one work information. In other words, a list of tasks to be performed on a given day for the project is displayed, and tasks that involve hazard prediction activities are displayed as selectable input options.

[0079] In a preferred embodiment of the present invention, only the work content related to the worker is displayed for selection and input. Specifically, the worker terminal device 3 transmits the worker identification information (such as the cooperating company user ID of the work reporter) and the login date and time included in the login information received from the worker to the work management device 1, and the display processing unit 18 processes and displays one or more work contents corresponding to the project in which the login date and time is included within the construction period and to which the worker identification information is linked.

[0080] In SC3 of Figure 8, the worker terminal device 3 accepts the selection input of one of the displayed work contents. Then, in SC04, the worker terminal device 3 transmits the selected work contents to the business management device 1 in addition to the request to display activity confirmation items, and in SC05, the display processing unit 18 processes and displays the activity confirmation item data corresponding to the selected work contents. In this embodiment, the display processing unit 18 refers to the activity confirmation item master registered in SA08 and processes and displays the activity confirmation item data corresponding to the work contents selected and entered in SC03.

[0081] Figures 10(a) to 10(c) show examples of activity result data input screens. In Figure 10(a), the categories of "Risk Assessment" are "Availability" and "Severity," and "Risk Reassessment," and the content of the "Risk Assessment" is displayed as "Availability" and "Severity," with levels 1 to 3 being selectable for input. In addition, "What hazards are present?" and "Mitigation measures" are displayed as input items for the activity result data.

[0082] In Figure 10(b), "Safety Confirmation Items" is displayed as the category of confirmation items in the activity confirmation item data, and "Protective Equipment, etc.", "Scaffolding Inspection, etc.", "Work at Height", "Change in Work Content", and "Use of Fire" are displayed as confirmation items according to the work content, and the options registered in SA08 are displayed in a pull-down format for selection input.

[0083] In Figure 10(c), "Today's Key Items / Action Goals, etc." is displayed as an input item for activity result data.

[0084] Then, in SC06 in Figure 8, the worker terminal device 3 receives activity result data input from the worker. In this embodiment, the worker terminal device 3 receives activity result data input from the worker via the activity result input screen shown in Figures 10(a) to (c).

[0085] In a preferred embodiment of the present invention, input history can be used when inputting activity result data. Specifically, for input items in which the input format of the activity result data is free-form text (for example, "What dangers are lurking?"), the database 2 stores input history information that associates the input content with the work content, and the display processing unit 18 refers to the input history information and displays one or more input contents associated with the work content selected and entered in SC03, making them selectable for input.

[0086] Furthermore, in a preferred configuration, input instructions for each branch can be displayed. Specifically, for input items where the input format of the activity result data is free-form text (for example, "What dangers are lurking?"), database 2 stores input instruction information that associates the administrator with the input instruction (for example, format-related instructions such as "When AA occurs, do BB and it becomes CC"). The display processing unit 18 then refers to the input instruction information and displays the input instruction corresponding to the administrator associated with the work content selected and entered in SC03, alongside the input field.

[0087] <5.3.2. Participant Registration Process> Register participants in hazard prediction activities in SC07-SC11.

[0088] <5.3.2.1. Displaying Candidate Participants> In SC07, the worker terminal device 3 sends a request to the business management device 1 to display the participant registration screen. In SC08, the display processing unit 18 identifies candidate participants by referring to the activity participation history information and entry / exit history information. In SC09, the device processes the display of the participant registration screen.

[0089] In this embodiment, the worker terminal device 3 transmits project identification information entered in SC01 to the work management device 1 in addition to the request to display the participant registration screen. In SC08, the display processing unit 18 refers to the activity participation history information and entry / exit history information corresponding to the project ID to identify candidate participants. Then, in SC09, the display processing unit 18 displays a participant registration screen that allows the user to select whether or not to register one or more of the identified candidate participants as activity participants.

[0090] Specifically, the display processing unit 18 displays workers who have a history of participating in hazard prediction activities corresponding to the received project ID within a predetermined period prior to the construction date (e.g., one week), and workers who have an entry / exit history corresponding to the project ID on the construction date, as candidates for participants in the hazard prediction activity. More specifically, in addition to the display request for the participant registration screen in SC07, the display processing unit 18 receives worker identification information (e.g., the user ID of the cooperating company of the work reporter and the worker's name, etc.), identifies workers (workers, etc.) linked to the worker identification information and project identification information, and registered in the activity participation history information, and identifies and displays these workers as candidates for participants. The display processing unit 18 also identifies and displays workers who are linked to the worker identification information and project identification information, and identified by matching the worker identification information in the entry / exit history information with the worker identification information in the worker information, as candidates for participants.

[0091] Figure 11 shows an example of a participant registration screen. In the example, one or more workers identified as potential participants based on their activity participation history are displayed in the "Participant Candidate List." Each participant candidate can be removed from the list by clicking the corresponding "×" icon. Additionally, by clicking the "Select Participants from Entry / Exit History Records" icon, the system references the entry / exit history information for the day of construction, and workers linked to the project ID and the worker identification information of the work reporter are displayed as participant candidates.

[0092] In a preferred embodiment of the present invention, participant candidates are displayed by referring to the activity participation history information, depending on whether or not they are registered in the entry / exit history information for the day of construction. Specifically, the display processing unit 18 identifies workers whose entry / exit history information is registered for the day of construction as participant candidates and processes them for display.

[0093] On the other hand, if entry and exit history information is not registered for a worker on the day of construction, the display processing unit 18 determines whether or not the worker has entry and exit history information corresponding to the project registered prior to the construction date. If the display processing unit 18 determines that the worker does not have entry and exit history information corresponding to the project registered prior to the construction date, it refers to the activity participation history information to identify a worker who was registered as an activity participant prior to the construction date and displays that worker as a candidate participant. On the other hand, if the display processing unit 18 determines that the worker has entry and exit history information corresponding to the project registered prior to the construction date, it does not identify that worker as a candidate participant. In other words, if a worker was registered as an activity participant via the access control device 5 during a previous construction project, it is assumed that they will also be registered as an activity participant via the access control device 5 during the current construction project. Therefore, if access history information is not registered via the access control device 5 during the current construction project, it is assumed that the worker is not participating in the construction work at all, and there is no need to display them as a candidate participant during the current construction project. This allows for efficient filtering of activity participants by preventing workers who are unlikely to participate in hazard prediction activities from being displayed as candidate participants.

[0094] Furthermore, in a preferred embodiment of the present invention, only workers who possess the prescribed entry qualifications for entering the construction site are displayed as participant candidates. Specifically, the display processing unit 18 refers to the worker information of the worker identified as a participant candidate, determines whether the worker has the prescribed entry qualification of "having completed safety training," and displays only the workers who possess this qualification as participant candidates. This narrows down the candidate list and makes it easier to register participants. Furthermore, if hazard prediction activities are conducted by workers who have not received safety training, the activities may be insufficient, and accidents due to inadequate verification can be prevented.

[0095] In a preferred embodiment of the present invention, the worker roster of the cooperating company and the predetermined entry qualifications are checked to display potential participants. Specifically, the display processing unit 18 identifies workers from among multiple workers belonging to the cooperating company associated with the project who have the predetermined entry qualification of "having completed safety training," and displays these workers as potential participants.

[0096] In addition, in a preferred embodiment of the present invention, activity qualification information associated with the worker who is a candidate participant is displayed. Specifically, the display processing unit 18 refers to the worker information and processes the activity qualification information associated with the worker identified as a candidate participant to display it in association with the candidate participant. This makes it possible to clearly identify who can carry out hazard prediction activities on the day of construction.

[0097] <5.3.2.2. Select and input non-participant in the activity> In SC10 in Figure 8, the activity registration unit 16 accepts the input of non-participants who are not participating in the hazard prediction activity from among the participant candidates displayed on the participant registration screen.

[0098] <5.3.2.3. Acquisition of participant images> In SC11, the worker terminal device 3 acquires participant images of workers who participated in the hazard prediction activity. In this embodiment, the worker terminal device 3 receives an image capture instruction from the work reporter and acquires participant images of workers who participated in the hazard prediction activity as activity participants. In the illustrated example in Figure 11, participant images acquired by accepting the press of the "Take a full photo" icon, or participant images stored in the storage unit 92 of the worker terminal device 3 and uploaded, are displayed on the same screen as the list of candidate participants.

[0099] <5.3.2.4. Registration of Activity Information> In SC12, the worker terminal device 3 transmits the activity results entered in SC06, the participant candidate designated as an activity participant in SC10, the participant image acquired in SC11, the project identification information entered in SC01, the work content selected and entered in SC03, the worker identification information of the work reporter, and an instruction to register the activity information to the work management device 1. Then, in SC13, the activity registration unit 16 registers the activity information linked to the participant candidate as an activity participant, the activity result data, the activity participant, the project ID, the work content, and the work reporter, as well as the participant image.

[0100] The process from SC01 to SC13 is completed, and the activity information registration process (C) is finished. This allows for the registration of participant images for each combination of project, work content, and work reporter, enabling more reliable management of the authenticity of hazard prediction activities.

[0101] In a preferred embodiment of the present invention, a warning notification is issued if the workers registered as activity participants do not include any workers with the prescribed qualifications. Specifically, the database 2 stores activity qualification information for each construction project, indicating the qualifications necessary to carry out hazard prediction activities. The notification unit 17, upon receiving input related to the registration of activity information, compares the activity qualification information corresponding to the construction project selected and entered in SC03 with the qualification information of one or more candidate workers to be registered as activity participants. If there are no candidate workers with the qualifications corresponding to the activity qualification information, it notifies the work reporter of a warning that there are no workers qualified to carry out hazard prediction activities.

[0102] <5.4. Activity Information Display Processing (D)> In the activity information display process (D), the process is executed up to the point where the administrator of the main contractor or other relevant party can view the registered activity information.

[0103] <5.4.1. Displaying Activity Information> In SD01, the administrator terminal device 4 receives input from the administrator regarding a request to display activity information and transmits the display request to the business management device 1. In SD02, the display processing unit 18 processes the activity information for display. In this embodiment, in addition to the request to display activity information, the administrator terminal device 4 transmits administrator identification information (such as the prime contractor's company ID) to the business management device 1. The display processing unit 18 refers to the construction system information, identifies the activity information for the project corresponding to the received administrator identification information, and processes the activity information for display. The administrator then checks the details of the desired activity information from the one or more activity information displayed.

[0104] The activity information display process (D) is completed when the processes SD01 to SD02 are executed. In this embodiment, the display processing unit 18 displays the activity result data in a way that prevents editing when the administrator views the activity information. On the other hand, the display processing unit 18 displays the candidate participants in an editable state.

[0105] As described above, the business management system 0 according to the present invention makes it possible to efficiently manage tasks related to hazard prediction activities for each project.

[0106] In a preferred embodiment of the present invention, an image registered as an activity image may be registered as a face image in the worker information. Specifically, the business management system 0 includes an authentication information registration unit (not shown), which compares the worker identification information (face information) of the worker information with the face information contained in the activity image acquired by the image acquisition unit 15. If there is face information in the activity image that does not match or resemble the face information of the participant candidate's worker information, the authentication information registration unit registers worker information that associates this face information with the worker identification information of the participant candidate worker for whom worker identification information has not been registered.

[0107] Furthermore, although this embodiment describes business management at a construction site, the same effects as the present invention can be obtained when the business management system 0 is used in fields other than construction sites. [Explanation of Symbols]
