Description

[Technical field]

[0001] The present invention relates to a risk prediction activity support system that supports risk prediction activities to prevent accidents by identifying risks and countermeasures according to the content of the work before starting the work, in order to perform work safely, for example, at civil engineering, construction, and maintenance and inspection sites. [Background technology]

[0002] Traditionally, at civil engineering and architectural construction sites and at the sites of structural maintenance and inspection, potential hazards in the work are identified and measures are taken to prevent accidents. As a means of doing so, hazard prediction activities are widely carried out in which each worker checks the hazards in the work and the measures to be taken before starting work.

[0003] For example, a hazard prediction activity uses a hazard prediction sheet (KY sheet) to extract specific details about the work and potential hazards in the work, and then lists measures to prevent accidents and records them on the hazard prediction sheet. However, writing by hand is inefficient, and it takes time to compile the hazard prediction sheets of each worker, accumulate them as a record of hazard prediction activities, and use them.

[0004] For this reason, as in Patent Documents 1 and 2, there is known a support system for risk prediction activities in which information such as that to be written on a risk prediction sheet is input and stored in a database using a terminal connected to a database via a communication line. Since the information on risk prediction activities is stored electronically, this information can be easily utilized. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 6917791 [Patent Document 2] Patent No. 7369885 Summary of the Invention [Problem to be solved by the invention]

[0006] In Patent Document 1, the details of the work, details of potential dangers, countermeasures, the severity and frequency of the danger, etc. are selected from options displayed on a terminal. However, as workers become accustomed to the system, they start to select without carefully reading the displayed contents, and risk prediction activities become meaningless. There is a risk that workers will carry out work without fully recognizing potential dangers, leading to accidents.

[0007] In addition, in Patent Document 2, the server automatically creates a hazard prediction sheet based on the worker's work content and presents it to the worker, which saves time and effort, but there is a risk that the worker will not be able to fully recognize potential hazards.

[0008] Therefore, an object of the present invention is to provide a danger prediction activity support system configured to enable a worker to fully recognize danger. [Means for solving the problem]

[0009] The hazard prediction activity support system of the invention of claim 1 has a server that stores information on hazard prediction activities, and a terminal that is equipped with a display means and an operation means for displaying information and is connected to the server via a communication line, and is configured to support hazard prediction activities to prevent accidents by displaying hazards and countermeasures according to work classification on the display means and confirming them in advance, wherein the hazard prediction activity includes each worker using the terminal to create and save a hazard prediction activity document to confirm hazards in his or her own work and countermeasures before starting the work, and the terminal is configured to display a plurality of description masters for identifying hazards and countermeasures corresponding to the work classification as options on the display means, sequentially display the plurality of description masters according to the description master selected by the worker, link the selected description masters to create the hazard prediction activity document, and save this hazard prediction activity document on the server as information on the hazard prediction activity.

[0010] According to the above configuration, when a worker uses a terminal to create a hazard prediction activity document that describes hazards and their countermeasures according to the task classification, multiple description masters that are continuations of the document are displayed according to the selected description master. When a worker selects a document while planning the document to be created, other options can be displayed to the worker to provide an opportunity to become aware of other possibilities. In addition, when creating a hazard prediction activity document, the worker can read the description master to select, thereby allowing the worker to fully recognize the hazards in the work and their countermeasures.

[0011] The danger prediction activity support system of the invention of claim 2 is characterized in that, in the invention of claim 1, it is configured to select the task classification before creating the danger prediction activity document. According to the above configuration, a task classification is selected before creating a hazard prediction activity document, so that the description master for identifying hazards is limited by the task classification, making it easier to create the hazard prediction activity document.

[0012] The danger prediction activity support system of the invention of claim 3 is characterized in that, in the invention of claim 1, the danger prediction activity text includes a danger prediction text describing a danger corresponding to the work classification, and a danger countermeasure text describing countermeasures corresponding to the danger prediction text. According to the above configuration, a worker who creates a hazard prediction activity document can clearly recognize hazards in the work by creating the hazard prediction document, and can clearly recognize countermeasures by creating a hazard countermeasure document while recognizing the hazards described in the hazard prediction document.

[0013] The danger prediction activity support system of the invention of claim 4 is characterized in that, in the invention of claim 3, the danger prediction text is created by linking, as the description master, a work situation master describing the work situation, a hazard object master describing objects that pose or are exposed to danger according to the work situation master, and a hazard state master describing states that pose danger or are exposed to danger according to the hazard object master. According to the above configuration, the danger prediction text is created by linking three elements: the work situation, the object corresponding to this work situation, and the possible danger of this object. Therefore, the danger in the work is clarified, and the worker can easily be aware of the danger.

[0014] The danger prediction activity support system of the invention of claim 5 is characterized in that, in the invention of claim 3, the danger countermeasure document is created by linking a work situation countermeasure master that describes the work situation and a danger countermeasure master that describes countermeasures corresponding to the work situation countermeasure master. According to the above configuration, the danger countermeasure text is created by linking two elements: the work situation and the countermeasure corresponding to this work situation. Therefore, the countermeasure for the danger in the work is clear, and the worker can easily be aware of the countermeasure.

[0015] The danger prediction activity support system of the invention of claim 6 is characterized in that, in the invention of claim 1, the multiple description masters displayed as the options are displayed in alphabetical order on the display means. According to the above configuration, when the worker is selecting the sentence to be created while thinking about it, the worker can quickly find the description master to select, and the danger prediction activity sentence can be created smoothly. On the other hand, even if the worker is not yet clear about the sentence to be created, reading the description master provides an opportunity to gain awareness in the danger prediction activity.

[0016] The danger prediction activity support system of the invention of claim 7 is characterized in that, in the invention of claim 1, it is configured so that characters can be input when selecting the description master. According to the above configuration, if the desired description is not available among the displayed options, the user can freely write and create a danger prediction activity document. Therefore, even if a danger or countermeasure is not registered in the description master, it can be reflected in the danger prediction activity. Effect of the Invention

[0017] According to the danger prediction activity support system of the present invention, workers can fully recognize danger. [Brief description of the drawings]

[0019] Hereinafter, the mode for carrying out the present invention will be described based on examples. EXAMPLES

[0020] First, the configuration of a danger prediction activity support system 10 will be described with reference to FIG. The danger prediction activity support system 10 is composed of 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 a display means for displaying information on work and an operation means. This danger prediction activity support system 10 supports danger prediction activities that prevent accidents by checking in advance the risks and countermeasures according to the content of the work.

[0021] Hazard prediction activities are activities in which each worker thoroughly recognizes potential hazards and their countermeasures before starting work in order to prevent accidents from occurring at work sites such as construction and civil engineering sites, and are very commonly performed. The hazard prediction activity support system 10 can effectively ensure that workers thoroughly recognize accident prevention, and also supports the accumulation of hazard prediction activity information and the easy tabulation and analysis of the information.

[0022] The server 11 is, for example, a computer equipped with an arithmetic unit, a storage unit, a communication unit, etc., and executes a program for providing the functions of the danger prediction activity support system 10. The terminal 20 is, for example, a portable electronic terminal such as a notebook PC, a tablet PC, or a smartphone, and supports danger prediction activities at the site while communicating with the server 11. The operation means of the terminal 20 is, for example, a touch panel, a touch pad, a software keyboard, a hardware keyboard, etc., provided over the display means (display).

[0023] As shown in Fig. 2, when a user logs in to the risk prediction activity support system 10 from a terminal 20, such as a tablet PC, via a site login screen 21 at the site, the screen transitions to an overall risk prediction activity record screen 22. From this overall risk prediction activity record screen 22, the user can switch between an individual risk prediction activity record screen 23 and a risk prediction activity record summary screen 24. On these overall risk prediction activity record screens 22 and others, multiple types of screens for displaying information are popped up as necessary. 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 meeting before work begins, to share information about hazard prediction activities with multiple surrounding workers and foremen, and to ensure a thorough understanding of accident prevention. The individual hazard prediction activity record screen 23 is used by each worker to extract and recognize potential hazards and countermeasures in his or her own work. At this time, the hazard prediction activity support system 10 supports the worker in creating a document (hazard prediction activity document) to identify potential hazards and countermeasures in his or her own work, and saves the created hazard prediction activity document. The saved hazard prediction activity document is shared as information about hazard prediction activities in the above-mentioned meeting.

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

[0026] The work classification field is configured so that the worker selects one of multiple pre-set work content masters that matches his / her work and determines the work classification. When the "Work Content" field of the work classification field is first touched, for example, at a building demolition site, multiple work content masters (scaffolding assembly and dismantling, work on scaffolding, building dismantling, etc.) are popped up as a list of options. The worker selects one work content master that matches the work at the site as the work content from the popped up list. The popped up list displays, for example, five options, and if there are more options than this, the rest of the list is displayed by operating the scroll bar located on the right side of the list. Note that the rest of the list can also be displayed by other operations such as swiping.

[0027] After the work content is selected, when the "Content details" column is touched, multiple content detail masters (signal person, etc.) pop up as a list of options, as shown in Figure 4. The worker selects one content detail master that matches his / her own work from the pop-up list. In this way, the worker selects the work content master and content detail master, and decides (specifies) the work classification by touching "Confirm" at the bottom of the work classification column.

[0028] After the task classification is specified, a plurality of description masters preset according to the task classification are displayed as a pop-up list, and the worker creates a hazard prediction activity document by selecting a description master from the list. The hazard prediction activity support system 10 supports the creation of a hazard prediction activity document that links the selected description masters by sequentially displaying a pop-up list of the next description master according to the description master selected by the worker.

[0029] The danger prediction activity sentence has a danger prediction sentence in a danger prediction column that describes potential dangers according to the work classification, and a danger countermeasure sentence in a countermeasure column that describes countermeasures corresponding to the danger prediction sentence. In the danger prediction activity support system 10, a work situation master, a danger target master, and a danger state master are preset as description masters for the danger prediction sentence, for example, as shown in Figures 5 to 7.

[0030] The work situation master describes the work situation, for example, "carrying scaffolding materials on one's back." By touching the "Hazard Prediction 1" column in the hazard prediction column, a pop-up list of multiple selectable work situation masters is displayed.

[0031] The hazard object master describes the object corresponding to the work situation master, for example, "scaffolding materials," and includes both objects that cause danger and objects that are at risk. By touching the "Hazard Prediction 2" column, a list of multiple selectable hazard object masters is displayed in a pop-up.

[0032] The hazard state master describes a state in which a hazard has been caused or in which a hazard has been incurred according to the hazard object master, for example, "Hit (heavy machinery)." By touching the "Hazard Prediction 3" column, a list of multiple selectable hazard state masters is displayed in a pop-up.

[0033] The worker selects one work situation master from the list of work situation masters displayed as in Figure 5, then selects one hazard object master from the hazard object masters displayed as in Figure 6. Then, selects one hazard state master from the list of hazard state masters displayed as in Figure 7, and finally touches "Confirm" at the bottom of the hazard prediction column. This links the selected work situation master, hazard object master, and hazard state master, and creates a hazard prediction statement, for example, "The scaffolding material is being carried on one's back and hit by it (a person)." If "Back" is touched, the user returns to the state before the decision was made in the work classification column.

[0034] After creating the danger prediction text, a danger countermeasure text is created according to the danger prediction text. In the danger prediction activity support system 10, a work situation countermeasure master and a danger countermeasure master are preset as description masters for the danger countermeasure text, for example, as shown in Figures 8 and 9.

[0035] The work situation countermeasure master describes the work situation, for example, "When transporting long objects." By touching the "Countermeasure 1" column, multiple selectable work situation countermeasure masters are displayed as a pop-up list. The hazard countermeasure master describes countermeasures corresponding to the work situation countermeasure master, for example, "Do not enter the operator's blind spot," and "Ensure that only authorized personnel are allowed to enter." By touching the "Countermeasure 2" column, multiple selectable hazard countermeasure masters are displayed as a pop-up list.

[0036] The worker selects one work situation countermeasure master from the displayed list of work situation countermeasure masters, then selects one hazard countermeasure master from the displayed list of hazard countermeasure masters, and touches "Decide" at the bottom of the countermeasure column. This links the selected work situation countermeasure master and the hazard countermeasure master, and creates a hazard countermeasure statement, for example, "When transporting long objects, do not allow anyone other than authorized personnel to enter." If the worker touches "Back," the worker returns to the state before the decision was made in the hazard prediction column.

[0037] The information on hazard prediction activities created using the terminal 20 in this way includes hazard prediction statements and hazard countermeasure statements according to the work classification, and is transmitted to the server 11 via the communication line 12 and stored in the server 11. The worker creates the hazard prediction statements and hazard countermeasure statements according to the work classification by reading and selecting from a plurality of description masters displayed as a list, or by selecting a description master that matches the statement he or she has conceived from the displayed list of description masters. This makes it possible to make the worker fully aware of potential hazards and their countermeasures, and efficiently raise awareness of accident prevention.

[0038] When the list of description masters is displayed as a pop-up, characters can be entered, for example, using a software keyboard, and description masters that match the entered characters are extracted and the list display is updated. When a worker has a hazard prediction activity sentence in mind, the worker can quickly display and select the description master he or she wants to select, making it easier to create a hazard prediction activity sentence. In addition, a sentence that is not on the list can be freely entered in the accompanying "Other" field to create a new hazard prediction activity sentence. Furthermore, after selecting a description master, it is also possible to freely enter new sentences to create an additional new hazard prediction activity sentence. Note that text can also be entered in the work classification field in the same way.

[0039] The description masters such as the work content master, the content detail master, and the work situation master, including their mutual correlations, are set in advance by the administrator of the danger prediction activity support system 10. In addition, the administrator adjusts the expressions, etc. of the characters entered and adds them as new description masters, etc. The description masters set by the administrator at first are extracted, for example, from past danger prediction sheets that have already been accumulated, but they can also be extracted from publicly available information on accident cases that are accessible via the communication line 12. At this time, for example, artificial intelligence (AI) technology may be used to extract the information so that it is comprehensive and without duplication.

[0040] Lists of description masters such as the work content master, content detail master, and work status master are displayed in alphabetical order. Compared to when the display order is set according to frequency of use, the opportunities to read the description masters are increased, which is expected to increase the opportunities for awareness in risk prediction activities, leading to the prediction of new risks and countermeasures, thereby improving the results of risk prediction activities. In addition, when conceiving a risk prediction activity document, the description master you want to select can be quickly displayed.

[0041] The information on hazard prediction activities stored in the server 11 can be displayed, for example, from the hazard prediction activity overall record screen 22 in Fig. 2, and is used in pre-work meetings, etc. In addition, the information compiled and analyzed from the hazard prediction activity record compilation screen 24 can be output, which can be used to confirm the effectiveness of hazard prediction activities and to make improvements.

[0042] The operation and effects of the above-mentioned danger prediction activity support system 10 will be described. When a worker creates a hazard prediction activity document that describes hazards and their countermeasures according to the task classification, a plurality of description masters that are continuations of the document are displayed on the display means of the terminal 20 used by the worker according to the selected description master. When the worker selects while planning the document to be created, other options can be displayed to the worker to provide an opportunity to become aware of other possibilities. In addition, by reading the description masters to select when creating a hazard prediction activity document, the worker can be made fully aware of the hazards in the work and their countermeasures.

[0043] In this case, the danger prediction activity document is created after selecting the task classification, so the description master for identifying danger is limited by the task classification, and the danger prediction activity document can be created smoothly. On the other hand, the worker who creates the danger prediction activity document can clearly recognize the danger in the work by creating the danger content document, and can clearly recognize the countermeasure by creating the danger countermeasure document while recognizing the danger described in the danger content document.

[0044] Hazard prediction text is created by linking the work situation master, which describes the work situation, the hazard object master, which describes the objects that pose or are exposed to hazards according to the work situation master, and the hazard state master, which describes the state in which the hazard is posed or exposed according to the hazard object master. In other words, hazard prediction text is created by linking three elements: the work situation (when), the object (what) that corresponds to this work situation, and the possible hazard (what will happen) for this object. This makes the hazard clear, making it easier for workers to be aware of the hazard.

[0045] Hazard countermeasures text is created by linking the work situation countermeasures master, which describes the work situation, with the hazard countermeasures master, which describes the countermeasures corresponding to the work situation countermeasures master. In other words, hazard countermeasures text is created by linking two elements, the work situation (when) and the countermeasures corresponding to this work situation (how to do it), so the countermeasures become clear and workers can easily be aware of them.

[0046] The multiple description masters displayed as options are displayed in alphabetical order on the display means. When the worker is selecting while thinking about the text to be created, he / she can quickly find the desired description master, which makes the creation of the hazard prediction activity text smooth. On the other hand, even if the worker is not yet clear about the text to be created, reading the description master provides an opportunity to gain awareness in hazard prediction activities.

[0047] The system is configured so that characters can be entered when selecting a description master. This allows the description master you want to select that matches your input to be displayed quickly, and even if the description you want to select is not among the displayed options, you can freely write it to create a risk prediction activity document. Therefore, even risks and countermeasures that are not set in the description master can be reflected in risk prediction activities.

[0048] In addition, a person skilled in the art can implement the present invention in a form in which various modifications are added to the above-described embodiment without departing from the spirit of the present invention, and the present invention includes such modifications.
