Description

Technical Field

[0001] The present invention relates to a method and a system for supporting on-site work, and more particularly, to a method and a system for supporting on-site work suitable for supporting risk prediction activities before the start of work.

Background Art

[0002] For example, when performing on-site work such as the installation work of an elevator, risk prediction activities are carried out before the start of work.

[0003] In the conventional risk prediction activities, a case collection based on past industrial accident cases is distributed to each worker in paper form and carried by them, and a case that matches the work content and site situation of the day is searched from the paper case collection, and the risk prediction activities are carried out.

[0004] However, the number of accident cases has been increasing year by year, and there is a problem that it takes time to search for accident cases that match the work content and site situation of the day.

[0005] In particular, when the experience of the worker or construction manager in charge of the construction site is shallow, the screening of accident cases that match the work content and site situation of the day becomes insufficient. As a result, the risk of industrial accidents and the detection of risks become insufficient, and there is a possibility that appropriate countermeasures against risks cannot be taken.

[0006] Here, as a technology related to danger prediction activities, for example, there is Patent Document 1. In FIG. 5 and the abstract of Patent Document 1, there are issues such as "providing a construction management system, a terminal device, and a program for a terminal device that realize the incorporation of construction quality and the education of construction workers, and improve the reliability of construction quality." and solutions such as "The terminal device 1 operated by the construction worker displays a safety information acquisition request (S201), acquires the requested safety information (S202), and transmits the acquired safety information (S203). After the acquisition and transmission of the safety information, the terminal device 1 displays a danger prediction information acquisition request (S204), acquires the danger prediction information for the request (S205), and transmits the acquired danger prediction information (S206). Based on the transmitted safety information and danger prediction information, the management staff makes a determination. Thereafter, the construction worker performs the construction work. After the work, the terminal device 1 acquires the construction quality information, transmits the acquired construction quality information, and receives the determination by the management staff." are described.

[0007] Here, regarding the safety information, in FIG. 4 and paragraph 0055 of Patent Document 1, it is described that "The control unit 10 provided in the terminal device 1 acquires the position information (S101), and extracts the required safety information, the required danger prediction information, and the required construction quality information from the on-site information database 11a recorded in the recording unit 11 based on the acquired position information (S102). In step S101, the terminal device 1 acquires the position information by, for example, a position acquisition unit 19 such as GPS. In step S102, the terminal device 1 extracts the acquired position information, the required safety information, the required danger prediction information, and the required construction quality information associated with the attribute information such as the construction site based on the position information from the on-site information database 11a." And in FIG. 9 and paragraph 0107 of Patent Document 1, it is described that "As illustrated in FIGS. 9(c) and 9(d), by selecting the content of the work from the image shown in FIG. 9(b), the work procedure manual related to the selected work is displayed as a request for the acquisition of safety information. The displayed work procedure manual describes, together with an illustration showing the outline of the work, specific work procedures, points for safety confirmation, and explanations regarding safety confirmation such as dangerous and harmful factors."

[0008] Also, regarding the danger prediction activity, in FIG. 11 and paragraph 0110 of Patent Document 1, "FIG. 11(b) shows an image displayed when 'danger prediction activity' is selected from the image shown in FIG. 11(a), and selection candidates such as 'backhoe work' and 'crane work' that are the targets of the danger prediction activity are displayed. And by selecting a selection candidate, a danger prediction information acquisition request is displayed. The displayed danger prediction information acquisition request is a request for acquisition of danger prediction information indicating that a danger prediction activity has been performed for the selected work. The acquisition of danger prediction information is, for example, processing such as generation of image information by imaging using the terminal device 1, generation of voice information by input (recording) of voice, etc. Specifically, acquisition of information such as an image of a worker performing a danger prediction activity, an image of a danger prediction activity form describing the content of the danger prediction activity in tabular form, and voice recording the situation of performing the danger prediction activity is required." is described.

Modes for Carrying Out the Invention

[0015] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each figure and each embodiment, the same or similar components are denoted by the same reference numerals, and duplicate descriptions are omitted.

Embodiment

[0016] FIG. 1 is a sequence diagram of the on-site work support method of Example 1. FIG. 2 is a block diagram showing an example of the overall configuration of the on-site work support system of Example 1. FIG. 3 is a block diagram showing an example of the configuration of the worker terminal of the on-site work support system of Example 1.

[0017] As shown in FIG. 2, the on-site work support system 1 of Example 1 includes a management server 10, a worker terminal 20, and a manager terminal 30 that are connected to each other via a network N. The on-site work support system 1 supports work at the site.

[0018] The on-site work support method of Example 1 will be described with reference to FIGS. 1 to 3.

[0019] In the work condition input step S1, the work condition input unit 24 of the worker terminal 20 causes the on-site worker to input the work content and the on-site situation via the input unit 22 of the worker terminal 20.

[0020] In Example 1, the work content related to the installation work of the elevator will be described as an example, but it is not limited to this, and it can be applied to work at various sites such as construction and building. The on-site situation preferably includes at least one of, for example, the type of building and weather information.

[0021] The input work content and the on-site situation are transmitted from the worker terminal 20 to the management server 10 via the network N (S2).

[0022] In the warning information extraction step S3, the warning information extraction unit 61 of the management server 10 refers to the warning information DB50 (DB is the abbreviation of database, the same hereinafter), which is one of the databases, and extracts the warning information corresponding to the input work content and the on-site situation.

[0023] The warning information preferably includes at least one of, for example, accident cases, in-house safety standards, and work precautions.

[0024] The extracted warning information is transmitted from the management server 10 to the worker terminal 20 via the network N (S4).

[0025] In the warning information display step S5, the warning information display unit 25 of the worker terminal 20 displays the extracted warning information on the display unit 21 of the worker terminal 20.

[0026] Even for the same work content, the risk of industrial accidents varies depending on the on-site situation. However, according to the on-site work support method of the first embodiment, the on-site worker can confirm the warning information suitable for carrying out the risk prediction activity before starting work, considering not only the work content but also the on-site situation. In addition, since there is no need to use a paper accident case collection, it is possible to extract and confirm appropriate warning information in a short time. When displaying accident cases, it is desirable to display a plurality of accident cases.

[0027] In the risk prediction result input step S6, the risk prediction result input unit 26 of the worker terminal 20 causes the on-site worker to input a risk prediction result based on the displayed warning information via the input unit 22 of the worker terminal 20.

[0028] The input risk prediction result is transmitted from the worker terminal 20 to the management server 10 via the network N (S7).

[0029] In the risk prediction result registration step S8, the risk prediction result registration unit 62 of the management server 10 associates the input risk prediction result with the site information 41 and registers it as risk prediction information 47 in the site information DB40, which is one of the databases.

[0030] As a result, there is no need to manage the risk prediction results on paper, and the construction manager can access the database via the manager terminal 30 and check the risk prediction results at any time. Also, even when the workers in charge of the construction site or the construction manager have little experience, it is possible to appropriately extract warning information such as accident cases according to the work content and site conditions of the day, and take appropriate measures against risks.

[0031] Next, the details of the on-site work support system of the first embodiment will be described with reference to FIGS. 2 and 3.

[0032] The management server 10 shown in FIG. 2 is, for example, an information processing device managed by the construction management department of a company that manages the progress of the installation site of an elevator and the safety management department of a company that manages the safety of the elevator installation site. The management server 10 manages, for example, the safety forms and site information of the elevator installation work. The management server 10 includes a site information DB40, a warning information DB50, a control unit 60, and a communication unit 65.

[0033] The management server 10 has a site information DB40 and a warning information DB50 as databases.

[0034] The on-site information DB40 is a database that registers and manages the implementation results of hazard prediction activities conducted at the construction site for each construction site. In the on-site information DB40, on-site information 41 is stored and managed for each site. Figure 2 shows an example where the on-site information 41 of Site A, Site B, and Site C is stored respectively. In the following description, the current site is Site A, and it is assumed that the control unit 60 accesses the on-site information 41 of Site A. Similarly, the worker terminal 20 is used by the on-site workers at Site A, and the manager terminal 30 is used by the construction manager at Site A. Since the on-site information 41 of Site B and Site C is the same, the description is omitted.

[0035] The on-site information 41 of Site A includes construction specification information 42, installation site related person information 43, work schedule 44, customer information 45, work execution form 46, and hazard prediction information 47.

[0036] The construction specification information 42 is information indicating the construction specifications of the elevator at Site A, which is the installation site.

[0037] The installation site related person information 43 is information that manages the names and affiliations of construction managers, on-site workers, material transporters, product designers, sales representatives, construction specification decision makers, etc. (hereinafter, these are collectively referred to as "site related persons") at the installation site by associating them with work IDs. Each work carried out at the installation site is identified by the work ID.

[0038] The work schedule 44 is information indicating the planned work schedule of each work process at the installation site.

[0039] The customer information 45 is information that manages the customer's responsible person, contact information, address, etc.

[0040] The work execution form 46 is a form that includes information such as work procedure manuals and work check sheets to be utilized during work execution.

[0041] The danger prediction information 47 is information including a danger prediction activity record form in which items to be input as danger prediction activities and a danger prediction result which is the implementation result of the danger prediction activity input by on-site workers according to the on-site situation are recorded. The form according to this embodiment is various information displayed on the worker terminal 20 and the manager terminal 30. Here, although the danger prediction activity is not stated as an item in the planned process, workers are required by the company managing the workers to carry out the danger prediction activity before starting work. The danger prediction activity is an activity of preliminarily listing up possible danger events that may occur in the work to be carried out on the work day before starting work and checking whether obstacles leading to danger can be eliminated. A danger level is defined for each assumed danger event, and the higher the danger level, the more likely it is to lead to a serious accident. Therefore, in the danger prediction activity, on-site workers are urged to conduct safety inspections before starting work so as to be able to eliminate danger events with a high danger level. By on-site workers carrying out the danger prediction activity, even if an accident occurs during work, it is expected to be limited to a minor accident.

[0042] The attention-arousing information DB 50 is a database that manages and stores accident cases 51 to be viewed on-site, internal safety standards 52, and work precautions 53 as an example of attention-arousing information. The attention-arousing information is not limited to these, and only a part of these may be used, or other information may be included.

[0043] The accident case 51 is information showing similar accident cases used in the danger prediction activity and is associated with the work content and the on-site situation. Regarding the association with the on-site situation, for each accident case, information indicating whether it corresponds only to a specific on-site situation such as an apartment or a rainy day or corresponds to all on-site situations without being limited to specific on-site situations may be provided. Note that it may not be classified by work content, but may be classified by type of disaster (such as falling, tumbling, being pinched, etc.). In that case, if a database for associating the work content with the type of disaster is additionally provided, the work content can be associated with the accident case. Also, it may be classified by work content and have information on the type of disaster.

[0044] The internal safety standard 52 is information indicating the safety standards defined in the internal regulations and is associated with the work content and the site situation. When the internal safety standards vary depending on the type of elevator, the information on the type of elevator may be included as part of the work content information. Since the concept of association is the same as that in accident case 51, the explanation is omitted. For example, when the type of disaster corresponding to the work content is falling or toppling, the internal safety standards related to falling or toppling, such as the method of attaching the safety belt, may be extracted.

[0045] The work precautions 53 are information indicating the precautions and particularly dangerous points according to the type of elevator and the work content and are associated with the work content and the site situation. The information on the type of elevator may be included as part of the work content information. Since the concept of association is the same as that in accident case 51, the explanation is omitted. For example, when the type of disaster corresponding to the work content is falling or toppling, the work precautions related to falling or toppling, such as the precautions when attaching the safety belt, may be extracted.

[0046] The control unit 60 includes a warning information extraction unit 61 and a danger prediction result registration unit 62.

[0047] When the communication unit 65 receives a request (e.g., an information acquisition request) from the worker terminal 20 or the administrator terminal 30 via the network N, it passes the request to the control unit 60. Also, when the communication unit 65 receives response information (e.g., screen information) from the control unit 60, it returns the response information to the worker terminal 20 or the administrator terminal 30, which is the source of the request, via the network N. However, in the following explanation of the processing of each functional unit of the control unit 60, the processing of the communication unit 65 is omitted, and it is explained that each functional unit directly transmits and receives various information and data to and from the worker terminal 20 or the administrator terminal 30.

[0048] Upon receiving an extraction request from the worker terminal 20 or the administrator terminal 30, the attention - arousal information extraction unit 61 extracts attention - arousal information corresponding to the work content and the on - site situation, which are the extraction conditions specified in the extraction request, from the attention - arousal information DB 50, and returns the extracted attention - arousal information to the requester as response information. At this time, it may also access the danger prediction information 47 and return to the requester as response information the items that should be input as danger prediction activities.

[0049] Upon receiving a registration request from the worker terminal 20 or the administrator terminal 30, the danger prediction result registration unit 62 registers the danger prediction result transmitted together with the registration request in the danger prediction information 47.

[0050] In addition to the above - mentioned functional units, the control unit 60 can receive various requests from the worker terminal 20 or the administrator terminal 30, process them, and give responses. However, the illustration and detailed description are omitted. As an example, it has a functional unit that receives an acquisition request from the worker terminal 20 or the administrator terminal 30, searches for information stored in the on - site information DB 40 and the attention - arousal information DB 50, and returns the search result to the requester as response information. Thereby, the worker terminal 20 or the administrator terminal 30 can search for, acquire, and display necessary information via the management server 10.

[0051] The worker terminal 20 is an example of an information - processing terminal operated by on - site workers at the installation site where elevator installation work is being carried out. As the worker terminal 20, a mobile terminal such as a mobile phone, a smartphone, a tablet - type mobile terminal, or a laptop - type personal computer is used. The on - site worker can easily operate the worker terminal 20 at the site. Then, the on - site worker can implement and input the danger prediction activities of the day through the application installed on the worker terminal 20.

[0052] As shown in FIGS. 2 and 3, the operator terminal 20 includes a display unit 21 for displaying various types of information, an input unit 22 for receiving information input by on-site operators, a control unit 23, and a communication unit 27. And the operator terminal 20 has functions similar to those of a general mobile terminal or the like. For example, the operator terminal 20 has a call function and a function of displaying, on the display unit 21, information acquired from the management server 10 via the network N.

[0053] The control unit 23 has a work condition input unit 24, a caution information display unit 25, and a danger prediction result input unit 26.

[0054] The work condition input unit 24 causes on-site operators to input work content and on-site conditions via the input unit 22.

[0055] The control unit 23 transmits an extraction request to the management server 10 using the input work content and on-site conditions as extraction conditions, and receives caution information extracted from the management server 10. This transmission of the extraction request and reception of the caution information may be performed by the work condition input unit 24 or the caution information display unit 25, or the work condition input unit 24 may perform the transmission of the extraction request and the caution information display unit 25 may perform the reception of the caution information, or an extraction request unit (not shown) may be provided to perform the extraction request.

[0056] The caution information display unit 25 displays the extracted caution information on the display unit 21 of the operator terminal 20.

[0057] The danger prediction result input unit 26 causes on-site operators to input a danger prediction result based on the displayed caution information via the input unit 22 of the operator terminal 20. Also, the danger prediction result input unit 26 transmits a registration request for the input danger prediction result to the management server 10.

[0058] In addition, the worker terminal 20 can also receive data on the work and work instruction content of the day from the management server 10. For example, on-site workers can start an application on the worker terminal 20 to view the construction specification information 42 at the construction site, view the specified work instruction content, or view the work instruction content and process schedule of the day.

[0059] The administrator terminal 30 is a terminal operated by the construction manager at the installation site. As the administrator terminal 30, a mobile terminal such as a mobile phone, smartphone, tablet-type mobile terminal, or laptop-type personal computer is used. Note that it is not limited to mobile terminals, and a terminal such as a desktop-type personal computer may also be used. The construction manager can confirm the danger prediction activities carried out on the same day for each site and the progress of the work through the application installed on the administrator terminal 30.

[0060] The administrator terminal 30 has functions similar to those of general desktop-type personal computers and mobile terminals, that is, functions capable of performing various processes such as calls, display, input, transmission, and reception of information via a network. The data of the process schedule 44 registered in the management server 10 is transmitted from the management server 10 in response to an access from the administrator terminal 30.

[0061] The administrator terminal 30 includes a display unit 31 for displaying various information and an input unit 32 for receiving information input by the construction manager. The administrator terminal 30 also has a control unit, a communication unit, etc., but their illustration and description are omitted.

[0062] The construction manager operates the administrator terminal 30 to create items to be input as danger prediction activities in the danger prediction activity record form for the installation site in charge by the construction manager via the input unit 32, and registers them in the management server 10. Then, the construction manager can confirm the danger prediction activity results at any time via the display unit 31 on the administrator terminal 30, so that the implementation status of the danger prediction activities at the installation site can be managed.

[0063] In addition, the administrator terminal 30 can execute all the functional units of the control unit 60 and the control unit 23.

[0064] Next, an example of the operation of the on-site work support system 1 will be described.

[0065] Before starting work on the day, the on-site worker selects Site A, which is the name of the site at the site, through the worker terminal 20, and obtains necessary information such as items to be input as hazard prediction activities stored in the hazard prediction information 47 from the site information 41 of Site A via the management server 10.

[0066] FIG. 4 and FIG. 5 are diagrams showing display examples of the worker terminal of the on-site work support system according to the first embodiment.

[0067] As shown in FIG. 4, the on-site worker inputs the hazard prediction leader, the hazard prediction implementation date, the hazard prediction implementation time, the weather, the machine type, the type of building, and the work content from the hazard prediction activity execution screen W1. Here, "light rain" is input as the morning weather, "cloudy" is input as the afternoon weather, "machine room less" is input as the type of elevator, "apartment" is input as the type of building, and "product loading" and "rail loading" are input as the morning work content.

[0068] Among these, those corresponding to the on-site situation are the weather and the type of building. Examples of the type of building include apartments, condominiums, high-rise buildings, and railway stations. In addition, as the on-site situation, the presence or absence of third parties such as other occupations and residents other than the elevator installation contractor may be input. Which items are to be input as the on-site situation can be set among the items to be input as the hazard prediction activity.

[0069] As an input method for the work content, for example, the left column is a selection column, and it is possible to select product loading, stage assembly, rail installation, entrance / exit installation, and installation of in-tower equipment / control panel from a drop-down list, and specific work content can be entered in the right column. Since the work content varies depending on the model, it is also possible to change the candidates in the drop-down list according to the model. Note that the work content may be selected from the selection column or freely entered in the column on the right side. Also, the data of the hazard prediction implementation date may be sent to the management server 10, the work content may be extracted from the process table 44, and displayed on the hazard prediction activity implementation screen W1. The information on the work content may include information on the model of the elevator. Note that when there is no work in the afternoon, it is left blank, but it may be selected, input, and displayed as "No work".

[0070] After entering the necessary information and pressing the send button in the lower right, the information entered into the management server 10 is sent, and the warning information corresponding to the entered work content and the on-site situation is sent from the management server 10.

[0071] As shown in FIG. 5, the warning information received from the management server 10 is displayed in the warning information column. Here, an example is shown where "Temporary placement of loaded / unloaded items", "Trolley transportation (rails)", "Unloading work", and "Related standards" are displayed as warning information for the morning work. A link is set for each displayed item, and when the link is clicked, one or more accident cases, in-house safety standards, and work precautions corresponding to that item and their links are displayed. The on-site worker can confirm the details of the accident cases, in-house safety standards, and work precautions by clicking on the link.

[0072] FIG. 6 is a diagram showing an example of the display of accident cases displayed on the worker terminal of the on-site work support system of Example 1.

[0073] On the accident case display screen W2, accident cases corresponding to the work content and the on-site situation are displayed, and it is possible to confirm the occurred event, the cause, and the countermeasures to prevent the same type of disaster.

[0074] Note that illustrations and explanations of the display examples of the in-company safety standards and work precautions are omitted.

[0075] After the on-site worker confirms the caution information displayed on the danger prediction activity execution screen W1, the worker conducts the danger prediction activity.

[0076] Specifically, the worker fills in each item in the "Assumed Danger" column and the "Measures against Causes of Danger" column shown in FIG. 5, and presses the send button in the lower right of the danger prediction activity execution screen W1. Thereby, the worker terminal 20 sends the danger prediction result to the management server 10. The management server 10 registers the sent danger prediction result in the danger prediction information 47.

[0077] The danger prediction activity is carried out as part of the safety measures at the work site. As described above, the danger prediction activity is an effort to prevent injuries during work by identifying the danger points that may lead to accidents or injuries from the work content and site conditions on the day and having all the people performing the work recognize them. As information used in the danger prediction activity, for example, various materials and forms such as procedures for elevator assembly work and introductions of cases of industrial accidents that occurred in the past in similar work are assumed. And the on-site worker can check these materials and forms at any time by the on-site work support system 1 of the first embodiment.

[0078] Next, a hardware configuration example of the computer 70 that constitutes each device of the on-site work support system 1 will be described.

[0079] FIG. 7 is a block diagram showing a hardware configuration example of a computer that realizes the on-site work support system of the first embodiment.

[0080] The computer 70 is an example of the hardware used as a computer that can operate as the management server 10, the worker terminal 20, or the administrator terminal 30 in Example 1. The on-site work support system 1 in Example 1 realizes an on-site work support method in which each function block shown in FIGS. 2 and 3 cooperates by each computer 70 (computer) constituting the server and the terminal executing a program.

[0081] The computer 70 includes a CPU (Central Processing Unit) 71, a ROM (Read Only Memory) 72, and a RAM (Random Access Memory) 73, which are respectively connected to a bus 74. Further, the computer 70 includes a display device 75, an input device 76, a non-volatile storage 77, and a network interface 78.

[0082] The CPU 71 reads the program code of the software that realizes each function in Example 1 from the ROM 72, loads it into the RAM 73, and executes it. Variables, parameters, etc. that occur during the arithmetic processing of the CPU 71 are temporarily written into the RAM 73, and these variables, parameters, etc. are appropriately read by the CPU 71. However, an MPU (Micro Processing Unit) may be used instead of the CPU 71. The functions of the control unit 60 of the management server 10, the control unit 23 of the worker terminal 20, the control unit of the administrator terminal 30, etc. are realized by the CPU 71. Although not shown in FIGS. 2 and 3, the worker terminal 20 and the administrator terminal 30 also have a CPU 71, a ROM 72, and a RAM 73, and the operations of each terminal are controlled by the CPU 71, etc.

[0083] The display device 75 is, for example, a liquid crystal display monitor, and displays the results of the processing performed by the computer 70 to the workers. For the input device 76, for example, a keyboard, a mouse, a touch panel, etc. are used, and it is possible for the workers to perform predetermined operation inputs and instructions. Note that the management server 10 may not be provided with the display device 75 and the input device 76.

[0084] As the non-volatile storage 77, for example, an HDD (Hard Disk Drive), an SSD (Solid State Drive), a flexible disk, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a magnetic tape, or a non-volatile memory or the like is used. In this non-volatile storage 77, in addition to an OS (Operating System) and various parameters, a program for operating the computer 70 is recorded. The ROM 72 and the non-volatile storage 77 record programs, data, etc. necessary for the CPU 71 to operate, and are used as an example of a computer-readable non-transitory storage medium storing a program executed by the computer 70. The on-site information DB 40 and the attention-calling information DB 50 shown in FIG. 2 are configured in the non-volatile storage 77 provided in the management server 10.

[0085] For the network interface 78, for example, a NIC (Network Interface Card) or the like is used, and various data can be transmitted and received between devices via a LAN (Local Area Network), a dedicated line, or the like connected to the terminals of the NIC. For example, the function of the communication unit 65 of the management server 10 is realized by the network interface 78. Also, the function of a communication unit that can be connected to the network N is realized by the network interfaces 78 of the worker terminal 20 and the manager terminal 30.

[0086] In the on-site work support system 1 of the first embodiment described above, a worker operates the worker terminal 20 and refers to attention-calling information (accident cases, in-house safety standards, work precautions, etc.) in daily danger prediction activities at a construction site, and inputs a danger prediction result. In the management server 10, the danger prediction result input to the worker terminal 20 is registered in the danger prediction information 47. The corresponding attention-calling information is displayed according to the work content and the on-site situation. Therefore, even when the experience of the worker or the construction manager in charge of the construction site is shallow, it is possible to appropriately identify the risk of industrial accidents and dangers.

[0087] In addition, the construction manager can check the implementation details of the on-site hazard prediction activities at any timing required by the construction manager, without directly checking the paper-based hazard prediction activity form at the construction site or making inquiries to the on-site workers. Therefore, it is possible to eliminate the labor of the construction manager's work and the impact of work delays caused by the construction manager due to the construction manager directly going to the site or making inquiries to the on-site workers.

[0088] In addition, the construction manager can grasp the implementation status of the hazard prediction activities at the installation site under his / her responsibility at the timing desired by the construction manager. Therefore, even if the construction manager is in charge of multiple installation sites, the construction manager can check the current implementation status of the hazard prediction activities at multiple installation sites without spending time.

[0089] In addition, the on-site workers can carry out hazard prediction activities through the worker terminal 20 before starting work on the day. Therefore, before starting work, the on-site workers can remove potential hazards that may cause accidents based on the hazard prediction activities, ensuring a safe working site.

[0090] In addition, the on-site workers can view and understand the details of the hazard prediction activities on the worker terminal 20. Also, the implementation status of the hazard prediction activities can be input by the on-site workers through a simple operation on the worker terminal 20. And when the hazard prediction activities have not been carried out, the on-site workers can input the reasons for non-implementation, etc. from the worker terminal 20, enabling the relevant workers to review the content of the hazard prediction activities.

Example

[0091] Example 2 is various modified examples of Example 1.

[0092] In the work condition input step S1, the work condition input unit 24 allows the input of the work content, the site situation, and the work date which is the date for implementing danger prediction. Therefore, the information on this work date is also transmitted to the management server 10, and the attention - calling information extraction unit 61 may extract the most recent accident cases 51 within a predetermined period from the work date in the attention - calling information extraction step S3 and add them as attention - calling information. The most recent accident cases to be extracted may not correspond to the work content or the site situation. This makes it possible to widely inform the most recent accident cases.

[0093] Also, when the worker terminal 20 is a high - performance terminal, the functions of the attention - calling information extraction unit 61 and the danger prediction result registration unit 62 of the control unit 60 of the management server 10 may be provided by the control unit 23 of the worker terminal 20. The same applies to the manager terminal 30. Also, in this case, instead of the management server 10, the site information DB40 and the attention - calling information DB50 may be stored in cloud storage so that they can be accessed via the network N.

[0094] When the danger prediction result input by the on - site worker is incorrect and different from the work content of the day, or when a work change occurs after registration, it may be possible to correct it within the day. Also, by enabling a safety inspector different from the on - site worker to conduct a safety inspection on - site using the manager terminal 30, it is also possible to recognize incorrect registration of the danger prediction result. Thereby, the construction manager can correctly manage the danger prediction result based on the danger prediction information 47.

[0095] As described above, the embodiments of the present invention have been explained, but the present invention is not limited to the configurations described in the embodiments, and various modifications are possible within the scope of the technical idea of the present invention. Also, some or all of the configurations described in each embodiment may be combined and applied.
