Also, within each construction site, multiple subcontractors are responsible for the implementation of construction work according to the work content (in the figure, subcontractors A and B for construction site 1, subcontractors C to E for construction site 2, construction (shown as subcontractors F and G of 3).

Construction work carried out by each subcontractor is carried out by multiple workers under a safety manager or leader (in the figure, the leader is indicated as α and the worker as β). . The main portable terminal 11 for creating activity data is handled by the leader α who manages the workers β.

In the database 10, all the activity data of the KY activities sent from the main mobile terminals 11 of the leaders α of the multiple cooperating companies in the multiple construction sites are accumulated. In other words, all activity data from all primary mobile terminals 11 are stored and aggregated in database 10 . Other data may be written and stored in the database 10 .

On the other hand, the management terminal device 12 is provided in the KY activity management department or the like for the purpose of company-wide management of the KY activities of all construction sites, and manages all the data of the KY activities accumulated in the database 10 .

The analysis support system is combined with a communication and distribution support system for risk prediction activities for construction work at civil engineering and construction sites (hereinafter referred to as a "communication and distribution support system"). The communication distribution support system uses the analysis results obtained by the support of the analysis support system to support communication and dissemination of the content with improved accuracy of KY activities.

The contact distribution support system includes, in addition to the configuration of the analysis support system, a secondary mobile terminal 14 such as a tablet PC or smart phone connected to the database 10 via a communication line 13 such as the Internet.

The secondary portable terminal 14 is used for viewing activity data of KY activities (of the construction work group (cooperating company) to which the worker belongs) stored in the database 10 . The sub-portable terminal 14 for browsing is handled by each worker β. That is, each worker β of all cooperating companies of all construction sites carries the secondary mobile terminal 14 .

Next, the structure of the database 10 and access rights of the management terminal device 12, the main mobile terminal 11 and the sub mobile terminal 14 to the structure of the database 10 will be described.

The database 10 has an analysis data area X, a data accumulation area Y, and a management data area Z. FIG. In the analysis data area X, data used for analysis for improving KY activities are accumulated and stored.

In the data accumulation area Y, all activity data created by all the main mobile terminals 11 are accumulated and stored. The activity data is created every day by the main mobile terminal 11 and stored in the data accumulation area Y for the period set for the daily activity data. Activity data is stored sequentially by date. In creating the activity data, discussions and meetings are held between the leader α or the like who handles the main portable terminal 11 and the worker β. A specific example of creating activity data will be described in detail later.

In the management data area Z, various management data for managing KY activities are accumulated and stored. For example, the management data does not include the contents of the KY activities themselves, but construction site information such as the address of the construction site, information on partner companies, and, as described later, in particular, the QR code (registered trademark) used when accessing the system. : hereinafter the same), and account registration data related to issuance of login IDs and passwords for permitting access to the database 10 itself.

The activity data created by the main mobile terminal 11 consists of direct items related to the content of the KY activity and indirect items specifying the name of the cooperating company, the name of the worker, the content of the work, and the like. Direct matters include at least danger matters and countermeasure matters. Dangers refer to specific dangers such as "stumbling on a step while carrying reinforcing bars", for example. The countermeasures refer to concrete countermeasures such as, for example, "Securing work passages with mesh roads after slab bar arrangement."

All of the main mobile terminals 11 create activity data including hazards and countermeasures according to the details of the work performed individually by each cooperating company. Of the activity data created by the main mobile terminal 11, at least hazards and countermeasures are used to enhance company-wide KY activities covering all construction sites and subcontractors. All are accumulated in the analysis data area X for the purpose of use for analysis.

Read creation and viewing access (indicated by arrow b in the figure) is enabled. The main portable terminal 11 is for creating activity data, and the writing function to the database 10 by this terminal creates activity data (KY activity table).

When creating activity data, the main mobile terminal 11 can read out and use the specific contents accumulated in the analysis data area X with regard to the dangers and countermeasures in the activity data. . Other activity data are created by input operations to the main portable terminal 11 . In addition, the content read from the analysis data area X regarding the danger items and countermeasure items is automatically selected according to the work content to be individually performed by each cooperating company.

The activity data created each day by the main mobile terminal 11, including the dangers and countermeasures read out from the analysis data area X, is accumulated in the data accumulation area Y as activity data created on that day. .

The main mobile terminal 11 can also create new risk items and countermeasure items and write them to the database 10 without reading them from the data area X for analysis. In this case, the newly created risk items and countermeasure items are included in the activity data and accumulated in the data accumulation area Y, and are also accumulated in the analysis data area X. FIG.

In addition, the main mobile terminal 11 has a reading function from the data accumulation area Y, so that activity data completed as a KY work table can be browsed.

If there is a primary contractor who manages a plurality of cooperating companies, the main mobile terminal of this primary contractor can access the data accumulation area Y of its own company and cooperating companies that require management.

The management terminal device 12 can access the analysis data area X, the data accumulation area Y, and the management data area Z for reading and writing of all data of KY activities for editing (indicated by arrow c in the figure). It is said that That is, the management terminal device 12 is allowed full access to the database 10 .

Editing access c specifically refers to reading the hazards and countermeasures accumulated in the analysis data area X, viewing them in the KY activity management department, and deleting duplicate content for these hazards and countermeasures. It includes a function that can be rewritten with the analysis results after performing analysis such as rewriting similar contents in a comprehensive manner and rewriting non-conforming items appropriately.

As a result, the risk items and countermeasure items in the analysis data area X include the risk items and countermeasure items written by the main mobile terminal 11 and edited by the management terminal device 12 .

In addition to the hazards and countermeasures written from the main mobile terminal 11, the management terminal device 12 can independently create separate hazards and countermeasures and write them to the analysis data area X. It's becoming In the management terminal device 12, in particular, it is possible to write and edit accident cases that actually occurred in the past and countermeasures devised for those cases (hereinafter referred to as "past cases"). The past cases are included in the hazards and countermeasures in .

Regarding the contents of the dangerous matters in the past cases, data indicating the degree of danger such as "serious accident" and "accident without lost workdays" is included in a viewable manner in order to encourage attention. These risk items and countermeasure items edited by the management terminal device 12 and stored in the analysis data area X can also be read by the main portable terminal 11 for creating activity data.

In the analysis data area X, hazards and countermeasures in daily KY activities and hazards and countermeasures in past cases are accumulated so that they can be read by the main mobile terminal 11 and the management terminal device 12 . The analysis data area X functions to support analysis of comprehensive KY activities in the KY activity management department equipped with the management terminal device 12 when considering the direction of measures for safety management.

In addition, the analysis data area X, which reflects and accumulates the results of analyzing the hazards and countermeasures of KY activities, including past cases, is mainly used when discussing and examining work details at each partner company. It functions to support creation of activity data by the mobile terminal 11 .

Enter the relevant information in the fields of "Date", "Weather", "Company Name", "Leader Name", "Type of Work", "Work Place", "Qualification Name", and "Name".

In the illustrated example, "Date" is selected from the calendar display icon, "Weather" is selected from the radio box, "Work type" is selected from the pull-down menu, and "Work location" and "Qualification name" are selected from " It can be input by selecting from a list-up menu corresponding to "type of work". Of course, you can also enter text.

The contents of the pull-down menu and the list-up menu are written and registered in the database 10 from the management terminal device 12 so as to be editable. The above contents can be used by clicking the "copy" button.

When scrolling, the display changes to that shown in FIG. The screen displays "Confirmation items", multiple "Danger points (corresponding to the above-mentioned dangers)", "Countermeasures (corresponding to the above-mentioned countermeasures)", "Possibility", "Severity", and "Priority". column is displayed.

For the "confirmation item", a plurality of applicable items can be selected according to the work content. When an item is selected by checking, a warning dialog (see FIG. 8A) corresponding to the item is displayed. Also, when the "display alert" button is clicked, all alert dialogs are displayed for each of the selected confirmation items.

A "dangerous point" can be input by selecting from a list-up menu corresponding to the "work type". Of course, you can also enter text. Regarding the list-up menu of "dangerous points", display rules should be applied. Specifically, as will be described later, in principle {descending order of evaluation score > descending order of severity > descending order of input frequency}, a dialog listing danger points is displayed (see FIG. 8(B)). .

In past cases, serious accidents (for example, accidents resulting in lost work time of 4 days or more, including fatal accidents and disability accidents) and accidents with no lost workdays (for example, minor accidents with lost work time of 3 days or less, including accidents without lost workdays) It is displayed first in the list-up menu, and then displayed in the above order of priority. In addition to the past cases, "serious accident" and "accident without lost workday", which are the data indicating the degree of risk described above, are displayed. The "danger point" selected in the dialog is entered.

"Countermeasures" displays a list of countermeasures (already entered) corresponding to the hazards entered in the "dangerous points" in a selectable manner in the dialog of the list-up menu (see FIG. 8(C)). Of course, you may input "danger point" and "countermeasure" as text.

The contents of the list-up menu used in these "dangerous points" and "countermeasures" are accumulated in the analysis data area on a daily basis in KY activities, and are also edited by the management terminal device 12 after undergoing analysis work. Then, it is written and registered in the analysis data area X, and is displayed based on whether it is a past case or not and on the order of priority.

By displaying them in this order, it is possible to confirm the items (past cases) that are weak points in the company's safety management, or the data (accumulated in the analysis data area X) that are listed as items that may be weak points. can be done. By displaying past cases and high-priority data first, workers will come into contact with that information repeatedly, making it easier for them to be aware of it.

When "dangerous points" and "countermeasures" are entered as text, the "possibility" column is set to "1 rarely (1 point)", "2 sometimes (2 points)", and "3 frequently ( 3 points)”, and for the “Severity” column, “1 non-lost time accidents (1 point)”, “2 lost time accidents (2 points)”, “3 death/disability ( 3 points)” rank.

The multiplication value of each selected item is displayed in the "Evaluation point" column in the "Priority" column.

When "dangerous points" and "countermeasures" are selected from the list-up menu, they have already been written from the main mobile terminal 11 and are already associated with the selection contents already written and registered from the management terminal device 12. "Likelihood", "Severity" and "Score" are displayed.

If the KY activity has already been selected multiple times before entering the activity data, the score is treated as an average value. In the "priority order" column, the rank is displayed by automatically calculating the magnitude of the "evaluation points" of a plurality of "danger points".

In the illustrated example, three "dangerous points" and the like are listed, and the ranks are set in three stages. If the number of enumerations such as "dangerous point" is too large, it may cause distraction, so it is preferable to set it appropriately so as not to be excessive.

When scrolling, the display transitions to that shown in FIG. In addition to the above, the screen displays columns for "confirmation of countermeasures for new visitors, etc.", "pointing and singing", "participants (workers)", and "total number of participants". For "pointing and singing", the content is entered as text or selected from a list-up menu corresponding to the "type of work". It is preferable to target the one with the highest priority.

In the "participants" column, when the "signature" column is clicked, a dialog for "signature input" is displayed as shown in FIG. and click “Confirm” to close the dialog. The column of "total number of participants" is automatically calculated and displayed from the number of signatures.

A "return" button, a "save" button, and an "output" button are provided at the bottom. The "return" button cancels the registration of the activity data and returns to the screen shown in FIG. Return to the screen and press the "Output" button to output the entered activity data.

When the activity data is registered in the data accumulation area Y by pressing the "Save" button, the above-mentioned "possibility", "significance" and "evaluation points" are stored in the data accumulation area Y. When there are multiple "dangerous points" in the data, it is possible to write multiplication points for each of the "probability" and "severity" ranks of the frequency of occurrence of the "dangerous points" in each of these "dangerous points". At the same time, the "priority" of these "risk points" is written in descending order of the "evaluation points" obtained by multiplying these "probability" and "severity" multiplication points.

As a result, when creating activity data on a daily basis, it is possible to easily recognize danger points that require special attention from "evaluation points" or "priority" and reflect them in KY activities, improving safety management. can be done.
