Hazard prediction activity support system

Abstract

We provide a hazard prediction activity support system that is configured to enable workers to fully recognize hazards. [Solution] A hazard prediction activity support system (10) has a server (11) that stores information on hazard prediction activities, and a terminal (20) that is equipped with information display means and operation means and is connected to the server via a communication line (12), and supports hazard prediction activities that prevent accidents by displaying hazards and countermeasures according to work classification on the display means for prior confirmation. Hazard prediction activities include each worker using the terminal to create and save a hazard prediction activity document for confirming hazards and countermeasures in their own work before starting work. The terminal displays multiple description masters for identifying work hazards and countermeasures as options on the display means, and sequentially displays the multiple description masters according to the description master selected by the worker, thereby concatenating the selected description masters to create a hazard prediction activity document, and saves this hazard prediction activity document as information on hazard prediction activities on the server.

Description

Technical Field

[0001] The present invention relates to a danger prediction activity support system that supports danger prediction activities for preventing accidents by confirming dangers and their countermeasures according to the content of work before starting work in order to work safely at civil engineering, construction, and maintenance inspection sites, for example.

Background Art

[0002] Conventionally, at civil engineering and construction sites and at the sites of maintenance inspections of structures, potential dangers in work are extracted and countermeasures are taken to prevent accidents. As a means, a danger prediction activity in which each worker confirms the dangers and their countermeasures in the work before starting work is widely carried out.

[0003] For danger prediction activities, for example, a method is adopted in which a danger prediction sheet (KY sheet) is used to specifically extract the content of work and potential dangers in the work, and countermeasures for preventing accidents are listed and described in the danger prediction sheet. However, for example, handwritten work is inefficient, and it takes time to aggregate the danger prediction sheets of each worker and accumulate and utilize them as records of danger prediction activities.

[0004] Therefore, for example, as in Patent Documents 1 and 2, there is known a danger prediction activity support system that uses a terminal connected to a database via a communication line to input information such as that described in a danger prediction sheet and store it in the database. Since the information on danger prediction activities is electronically accumulated, this information can be easily utilized.

Summary of the Invention

[0006] Patent Document 1 describes how workers select the content of the work, the nature of potential hazards, countermeasures, the severity of the hazards, and the frequency of occurrence from options displayed on a terminal. However, as workers become accustomed to the system, they may start selecting options without carefully reading the displayed content, rendering the hazard prediction activity meaningless. This could lead to accidents as workers perform tasks without fully recognizing potential hazards.

[0007] Furthermore, in Patent Document 2, the server automatically creates and presents a hazard prediction sheet to the worker according to the worker's work content, which is convenient, but there is a risk that the worker may not be able to fully recognize potential hazards.

[0008] Therefore, the present invention aims to provide a hazard prediction activity support system configured to enable workers to adequately recognize hazards. [Means for solving the problem]

[0009] The hazard prediction activity support system of the invention of claim 1 comprises a server for storing information on hazard prediction activities, and a terminal equipped with display means and operation means for displaying information and connected to the server via a communication line, and is configured to support hazard prediction activities that prevent accidents by displaying hazards and countermeasures according to work classification on the display means for prior confirmation, wherein the hazard prediction activity includes each worker creating and saving a hazard prediction activity document using the terminal to confirm hazards and countermeasures in their own work before starting work, and the terminal is configured to display a plurality of description masters as options for identifying hazards and countermeasures corresponding to the work classification on the display means, and sequentially display the plurality of description masters according to the description master selected by the worker, thereby concatenating the selected description masters to create the hazard prediction activity document, and save this hazard prediction activity document as information on hazard prediction activities on the server.

[0010] With the above configuration, when a worker uses a terminal to create a hazard prediction activity document describing hazards and countermeasures according to the work classification, multiple description masters that continue the document are displayed according to the selected description master. When a worker is selecting while conceptualizing the document they intend to create, other options can be displayed to give the worker an opportunity to become aware of other possibilities. In addition, by reading the description masters in order to make selections when creating a hazard prediction activity document, workers can be made to fully understand the hazards in the work and the countermeasures.

[0011] The hazard prediction activity support system of claim 2 is characterized in that, in the invention of claim 1, it is configured to select the work classification before creating the hazard prediction activity document. With the above configuration, since the hazard prediction activity document is created after selecting the work category, the description master for identifying hazards is limited by the work category, making the creation of the hazard prediction activity document smoother.

[0012] The hazard prediction activity support system of the invention of claim 3 is characterized in that, in the invention of claim 1, the hazard prediction activity document includes a hazard prediction document describing hazards corresponding to the work classification and a hazard countermeasure document describing countermeasures corresponding to the hazard prediction document. According to the above structure, workers who create hazard prediction activity documents can clearly recognize hazards in their work by creating the documents, and can clearly recognize countermeasures by creating hazard countermeasure documents while having recognized the hazards described in the hazard prediction documents.

[0013] The hazard prediction activity support system of the invention of claim 4 is characterized in that, in the invention of claim 3, the hazard prediction text is created by linking the following as the description master: a work situation master that describes the work situation; a hazard target master that describes the objects that cause or suffer hazards corresponding to the work situation master; and a hazard state master that describes the state in which a hazard has been caused or suffered hazards corresponding to the hazard target master. According to the above structure, a hazard prediction document is created by linking three elements: the work situation, the object corresponding to this work situation, and the potential hazards that may occur with respect to this object. Therefore, the hazards in the work become clearer, and workers become more aware of the hazards.

[0014] The hazard prediction activity support system of the invention of claim 5 is characterized in that, in the invention of claim 3, the hazard countermeasure document is created by linking a work situation countermeasure master that describes the work situation and a hazard countermeasure master that describes countermeasures corresponding to the work situation countermeasure master. According to the above structure, a hazard prevention document is created by linking two elements: the work situation and the countermeasures corresponding to that work situation. Therefore, countermeasures for hazards in the work become clear, and workers are more likely to be aware of the countermeasures.

[0015] The hazard prediction activity support system of claim 6 is characterized in that, in the invention of claim 1, the plurality of description masters displayed as options are displayed in alphabetical order on the display means. With the above configuration, when a worker is conceptualizing and selecting the text they intend to create, they can quickly find the description master they want to select, making the creation of hazard prediction activity documents smoother. On the other hand, even if the text the worker intends to create is not yet clear, reading the description master provides an opportunity to gain insights into hazard prediction activities.

[0016] The hazard prediction activity support system of claim 7 is characterized in that, in the invention of claim 1, it is configured to allow text input when selecting the description master. According to the above configuration, if the desired description is not among the displayed options, users can freely write their own description to create a hazard prediction activity document. Therefore, even hazards and countermeasures not registered in the description master can be reflected in hazard prediction activities. [Effects of the Invention]

[0017] According to the hazard prediction activity support system of the present invention, workers can adequately recognize hazards.

Modes for Carrying Out the Invention

[0019] Hereinafter, modes for carrying out the present invention will be described based on embodiments.

Embodiment

[0020] First, the configuration of the danger prediction activity support system 10 will be described based on FIG. 1. The danger prediction activity support system 10 includes a server 11 that stores information on danger prediction activities, and a terminal 20 that is connected to the server 11 via a communication line 12 and has display means and operation means for displaying information related to work. The danger prediction activity support system 10 supports a danger prediction activity for preventing accidents by pre-checking dangers and their countermeasures according to the content of work.

[0021] Hazard prediction activities are very common practices, such as those used in construction and civil engineering work sites, where workers are required to identify potential hazards and countermeasures before starting work to ensure a thorough understanding of accident prevention. The hazard prediction activity support system 10 effectively ensures that workers are thoroughly aware of accident prevention, and also supports the accumulation, aggregation, and analysis of information from hazard prediction activities.

[0022] Server 11 is a computer equipped with, for example, a computing unit, memory device, communication device, etc., and runs a program to provide the functions of the hazard prediction activity support system 10. Terminal 20 is a portable electronic terminal such as a notebook PC, tablet PC, or smartphone, and supports on-site hazard prediction activities while communicating with Server 11. The operating means of Terminal 20 is, for example, a touch panel, touchpad, software keyboard, hardware keyboard, etc., mounted on top of a display.

[0023] As shown in Figure 2, when logging into the hazard prediction activity support system 10 from a terminal 20, such as a tablet PC, via the field login screen 21, the system transitions to the overall hazard prediction activity record screen 22. From this overall hazard prediction activity record screen 22, it is possible to switch between the individual hazard prediction activity record screen 23 and the hazard prediction activity record summary screen 24. On these overall hazard prediction activity record screens 22, etc., multiple types of screens are displayed as pop-ups to show information as needed. Furthermore, the display is optimized by varying the display layout depending on the type of terminal 20.

[0024] The overall hazard prediction activity record screen 22 and the hazard prediction activity record summary screen 24 are used, for example, in a pre-work meeting to share information on hazard prediction activities with multiple workers and foremen and to ensure thorough awareness of accident prevention. The individual hazard prediction activity record screen 23 is used when each worker extracts and recognizes potential hazards and countermeasures in their own work. At this time, the hazard prediction activity support system 10 assists workers in creating a document (hazard prediction activity document) to confirm potential hazards and countermeasures for their own work, and saves the created hazard prediction activity document. The saved hazard prediction activity document is shared as information on hazard prediction activities in the meeting described above.

[0025] The display of terminal 20 shows information on hazard prediction activities displayed on the personal hazard prediction activity record screen 23, including, for example, a work classification column on the left, a hazard prediction column in the center showing potential hazards, and a hazard countermeasures column on the right, as shown in Figure 3. From the KY details in the upper right, it is possible to view, for example, past accident cases.

[0026] The work classification section is configured so that workers can select a work classification from several pre-configured work content masters that match their work. When the "Work Content" field in the work classification section is first touched, for example, at a building demolition site, multiple work content masters (scaffolding assembly / disassembly, scaffolding work, building demolition, etc.) will pop up as a list of options. The worker selects one work content master from the pop-up list that matches the work at the site. The pop-up list will display, for example, five options, and if there are more options to choose from, the rest of the list will be displayed by operating the scroll bar located on the right side of the list. In addition, the rest of the list can also be displayed by other operations, such as swiping.

[0027] After the task content is selected, touching the "Content Details" field will display a pop-up list of multiple content detail masters (such as signalers) as shown in Figure 4. The worker selects one content detail master that matches their task from the pop-up list. In this way, the worker selects the task content master and content detail master, and then touches "Confirm" at the bottom of the task classification field to determine (specify) the task classification.

[0028] After identifying the work category, a list of pre-configured description masters corresponding to this work category pops up, and the worker selects a description master from this list to create a hazard prediction activity document. The hazard prediction activity support system 10 assists in creating a hazard prediction activity document by sequentially displaying a list of the next description master in response to the description master selected by the worker.

[0029] A hazard prediction activity document consists of a hazard prediction document in the hazard prediction section, which describes potential hazards according to the work classification, and a hazard countermeasure document in the countermeasure section, which describes countermeasures corresponding to the hazard prediction document. The hazard prediction activity support system 10 has pre-configured description masters for the hazard prediction document, such as the work status master, the hazard target master, and the hazard status master, as shown in Figures 5 to 7.

[0030] The work status master describes the work situation, for example, "carrying scaffolding materials." Touching the "Hazard Prediction 1" field in the Hazard Prediction section will display a pop-up list of selectable work status masters.

[0031] The hazard target master describes targets corresponding to the work situation master, such as "scaffolding materials," and includes both targets that cause hazards and targets that are susceptible to hazards. Touching the "Hazard Prediction 2" field will display a pop-up list of selectable hazard target masters.

[0032] The hazard status master describes a state in which a hazard has been caused or suffered, corresponding to the hazard target master, for example, "Hit. (Heavy machinery)." Touching the "Hazard Prediction 3" field will display a pop-up list of selectable hazard status masters.

[0033] The worker selects one work status master from the list of work status masters displayed as shown in Figure 5, then selects one hazard object master from the list of hazard object masters displayed as shown in Figure 6, and then selects one hazard state master from the list of hazard state masters displayed as shown in Figure 7, and finally touches "Confirm" at the bottom of the hazard prediction section. This links the selected work status master, hazard object master, and hazard state master, and creates a hazard prediction sentence, for example, "While carrying scaffolding material, the scaffolding material hits (a person)." If "Back" is touched, the user returns to before the confirmation in the work classification section.

[0034] After creating a hazard prediction document, a hazard countermeasure document corresponding to this document is created. The hazard prediction activity support system 10 has pre-configured description masters for the hazard countermeasure document, such as the work situation countermeasure master and the hazard countermeasure master, as shown in Figures 8 and 9.

[0035] The work situation countermeasure master describes the work situation, for example, "When transporting long objects." Touching the "Countermeasure 1" field displays a pop-up list of selectable work situation countermeasure masters. The hazard countermeasure master describes countermeasures corresponding to the work situation countermeasure master, for example, "Do not enter the operator's blind spot," or "Prohibit entry to unauthorized personnel." Touching the "Countermeasure 2" field displays a pop-up list of selectable hazard countermeasure masters.

[0036] The worker selects one work situation countermeasure master from the displayed list, then selects one hazard countermeasure master from the displayed list, and touches "Confirm" at the bottom of the countermeasure column. This links the selected work situation countermeasure master and hazard countermeasure master, and creates a hazard countermeasure statement, such as "When transporting long objects, entry is prohibited to unauthorized personnel." Touching "Back" returns to the point before the hazard prediction column was confirmed.

[0037] The information on hazard prediction activities created using terminal 20 includes hazard prediction text and hazard countermeasure text corresponding to the work classification, and is transmitted to server 11 via communication line 12 and stored on server 11. Workers create hazard prediction text and hazard countermeasure text, which are countermeasures, according to the work classification by reading and selecting from multiple description masters displayed as a list, or by selecting a description master that matches the text they have conceived from the displayed list of description masters. Therefore, potential hazards and their countermeasures can be made sufficiently aware of to the workers, and awareness of accident prevention can be efficiently raised.

[0038] With the list of description masters displayed in a pop-up window, users can, for example, type characters using a software keyboard. This will extract the description masters that match the entered characters and update the list display. This allows users to quickly display and select the desired description master when they already have a hazard prediction activity document in mind, streamlining the creation of hazard prediction activity documents. Furthermore, users can freely enter text not found in the list into the accompanying "Other" field to create new hazard prediction activity documents. Additionally, it is possible to select a description master and then freely enter new text to create additional new hazard prediction activity documents. Text input is also possible in the work classification field.

[0039] Description masters such as the work content master, content detail master, and work status master are pre-configured by the administrator of the hazard prediction activity support system 10, including their interrelationships. This administrator also adjusts the wording and other aspects of entered text and adds them as new description masters. The description masters initially configured by the administrator are extracted, for example, from already accumulated past hazard prediction sheets, but can also be extracted from publicly available accident case information obtainable via the communication line 12. In this case, artificial intelligence (AI) technology may be used to extract data comprehensively without duplication.

[0040] The lists of description masters, such as the work content master, content detail master, and work status master, are displayed in alphabetical order. Compared to setting the display order based on frequency of use, this increases the opportunities to read the description masters, which is expected to increase opportunities for awareness in hazard prediction activities, leading to the prediction of new hazards and countermeasures, thereby greatly improving the results of hazard prediction activities. In addition, when drafting a hazard prediction activity document, the desired description master can be displayed quickly.

[0041] The information on hazard prediction activities stored on server 11 can be displayed, for example, from the overall hazard prediction activity record screen 22 in Figure 2, and can be used in situations such as pre-work meetings. In addition, the aggregated and analyzed data can be output from the hazard prediction activity record summary screen 24, which can be used to confirm and improve the effectiveness of hazard prediction activities.

[0042] The operation and effects of the above-mentioned hazard prediction activity support system 10 will be explained. When a worker creates a hazard prediction activity document outlining hazards and countermeasures according to the work classification, the display means of the terminal 20 used by the worker displays multiple description masters that continue the document according to the selected description master. When a worker is selecting while conceptualizing the document they intend to create, other options can be displayed to give the worker an opportunity to become aware of other possibilities. Furthermore, by reading the description masters in order to make a selection when creating a hazard prediction activity document, the worker can be made to fully understand the hazards in the work and the countermeasures.

[0043] In this process, since the work classification is selected before creating the hazard prediction activity document, the description master for identifying hazards is limited by the work classification, making the creation of the hazard prediction activity document smoother. On the other hand, the worker creating the hazard prediction activity document can clearly recognize the hazards in the work by creating the hazard description document, and can clearly recognize the countermeasures by creating the hazard countermeasure document while having recognized the hazards described in the hazard description document.

[0044] Hazard prediction documents are created by linking three master data sets: a work situation master that describes the work situation, a hazard target master that describes the objects that cause or are affected by the hazard corresponding to the work situation master, and a hazard state master that describes the state in which the hazard was caused or the state in which the hazard was affected, corresponding to the hazard target master. In other words, hazard prediction documents are created by linking three elements: the work situation (when), the object corresponding to this work situation (what), and the hazard that may occur with respect to this object (what happens). Consequently, the hazards become clearer, and workers are more likely to be aware of them.

[0045] Hazard prevention documents are created by linking a work situation countermeasure master, which describes the work situation, with a hazard prevention master, which describes the countermeasures corresponding to the work situation countermeasure master. In other words, hazard prevention documents are created by linking two elements: the work situation (when it occurs) and the countermeasures that correspond to this work situation (what to do), so the countermeasures become clear and workers are more likely to be aware of them.

[0046] The multiple description masters displayed as options are shown in alphabetical order on the display device. When workers are conceptualizing the text they intend to create, they can quickly find the description master they want to select, making the creation of hazard prediction activity documents smoother. On the other hand, even if the text the worker intends to create is not yet clear, reading the description masters can provide an opportunity to gain insights into hazard prediction activities.

[0047] The system is configured to allow text input when selecting a description master. This allows users to quickly display the desired description master that matches their input, and even if the desired description is not among the displayed options, they can freely enter their own description to create a hazard prediction activity document. Therefore, even hazards and countermeasures not set in the description master can be reflected in the hazard prediction activity.

[0048] Furthermore, those skilled in the art can implement the present invention in various forms with modifications to the above embodiments without departing from the spirit of the invention, and the present invention encompasses such modifications. [Explanation of symbols]
