  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram showing a schematic configuration of a work safety management system 10 according to the present embodiment. The work safety management system 10 includes a management device 20 connected to the wired network 8 to the Internet 9, a mobile terminal 5 of a plurality of workers 99 connected to the Internet 9 by a wireless network 7, a beacon transmitter 4, a beacon receiver. 6. The management device 20 includes a data receiving server 1, a data storage database 2, and a data analysis server 3.

  Although details will be described later, the mobile terminal 5 is a mobile phone or a smart phone, has a Bluetooth (registered trademark) BLE communication function as a short-range wireless communication function, uses an iBeacon (registered trademark) technology, and uses a beacon transmitter. 4 and the beacon receiver 6. Hereinafter, transmission / reception (communication) of a beacon signal using iBeacon is referred to as beacon communication. In the work safety management system 10, work on the work object 90 of the worker 99 having the mobile terminal 5 is managed using beacon communication. Technologies such as an infrared beacon and an optical beacon may be used as the beacon.

  The data receiving server 1 receives data from the mobile terminal 5 and the beacon receiver 6. The data accumulation database 2 accumulates data received by the data receiving server 1. The data analysis server 3 analyzes the accumulated data in the data accumulation database 2.

  The beacon transmitter 4 is set with a beacon ID and is equipped with an acceleration sensor. The beacon transmitter 4 is attached to the work object 90 and transmits the beacon ID and the value of the acceleration sensor as beacon information by a beacon radio wave (beacon signal) of iBeacon specification.

  As described above, the mobile terminal 5 is equipped with a short-range wireless communication function and an acceleration sensor. The mobile terminal 5 is set with a mobile terminal ID. The portable terminal 5 receives the beacon signal from the beacon transmitter 4 and receives the beacon ID and the acceleration sensor value included in the beacon signal via the network (wireless network 7, Internet 9, wired network 8). Send to server 1. At this time, the portable terminal 5 can further transmit the received electric field strength of the beacon signal using the portable terminal ID and the value of the acceleration sensor of the portable terminal 5 as portable terminal information together with the above-described beacon information.

  The beacon receiver 6 is installed near the work object 90, receives a beacon signal radio wave, and transmits a beacon ID and a beacon acceleration sensor value included in the beacon signal to the data reception server 1.

  The data analysis server 3 of the management device 20 allows the worker to be safe based on the value of the acceleration sensor of the beacon transmitter 4, the value of the acceleration sensor of the mobile terminal 5, and the value of the received electric field strength of the beacon signal. It is determined whether or not a proper work is being performed.

  The data analysis server 3 holds a table in which types of work objects 90, beacon IDs, required work numbers, and information on whether or not to consider acceleration data are associated with each other. For example, when the heavy work object 90 is transported, two or more workers 99 are necessary, and the work object 90 (for example, a ladder or firearms) for performing work with a high degree of risk is used. Work requires two or more workers 99. Therefore, in the table, for each work object 90, information indicating the type (heavy object, ladder, firearm, etc.), beacon ID, information indicating whether or not to consider acceleration data (a flag may be used), Information (minimum number of workers) indicating the number of work required persons (for example, two persons) is associated. When the work object 90 is heavy, the beacon ID of the beacon transmitter 4 attached to the heavy object, information indicating that acceleration data is considered, and information indicating the number of workers are registered as data. Is done. Thereby, the data analysis server 3 can determine whether two or more persons are carrying heavy objects. When the work object 90 is a ladder or a firearm, beacon IDs attached thereto, information indicating that acceleration data is not considered, and information indicating the number of workers are registered as data. Thereby, the data analysis server 3 can determine whether the work of the work target 90 is performed by a plurality of persons.

  As described above, the data analysis server 3 appropriately performs the work of the work target 90 by the workers 99 of the necessary work number based on the signals received from the portable terminal 5 and the beacon receiver 6 based on the table. Judge whether or not.

The beacon transmitter 4 attached to the work object 90 acquires its beacon information, that is, “beacon ID” and “beacon acceleration sensor value” (S21), and transmits them to the beacon receiver 6 (S22).

  The beacon receiver 6 receives the beacon information from the beacon transmitter 4, that is, the “beacon ID” and “beacon acceleration sensor value” (S23), and transmits them to the data receiving server (S24).

  When receiving data from the beacon receiver 6 (S25), the data receiving server 1 writes it in the data storage database 2 together with the reception time (S26). The data accumulation database 2 sequentially accumulates the reception data written from the data reception server 1 (S27).

  FIG. 3 is a chart showing a process of storing received data from the mobile terminal 5 (S30). The beacon transmitter 4 attached to the work object 90 acquires its own beacon information, that is, “beacon ID” and “beacon acceleration sensor value” (S31), and transmits them to the portable terminal 5 (S32).

  The portable terminal 5 receives the beacon information from the beacon transmitter 4, that is, “beacon ID” and “beacon acceleration sensor value” (S33), acquires the “reception electric field strength” at that time (S34), and further the portable terminal 5 Own mobile terminal ID, that is, “mobile terminal ID” “mobile terminal acceleration sensor value” is acquired (S35).

  The mobile terminal 5 transmits beacon information (“beacon ID” “beacon acceleration sensor value”), “received electric field strength”, and mobile terminal information (“mobile terminal ID” “mobile terminal acceleration sensor value”) to the data receiving server 1. (S36).

  When receiving data received from the portable terminal 5 (S37), the data receiving server 1 writes it in the data storage database 2 together with the reception time (S38). The data storage database 2 sequentially stores the reception data written from the data reception server 1 (S39).

  FIG. 4 is a chart showing beacon movement determination processing (S40). As a premise, data related to the beacon transmitter 4 is accumulated in the data accumulation database 2 by the received data accumulation process (S20) from the beacon receiver 4 of FIG. The data analysis server 3 extracts the accumulated data, here, “beacon ID” and “beacon acceleration sensor value” which are beacon information from the data accumulation database 2 (S41). Furthermore, the data analysis server 3 determines whether or not the beacon transmitter 4 has moved from the “beacon acceleration sensor value” (S42).

  FIG. 5 is a chart showing the beacon periphery number determination process (S50). As a premise, data related to the portable terminal 5 is accumulated in the data accumulation database 2 by the received data accumulation process (S30) from the portable terminal 5 of FIG. The data analysis server 3 extracts the stored data, here “beacon ID”, “mobile terminal ID”, and “reception field strength value” from the data storage database 2 (S51).

  The data analysis server 3 estimates the distance between the beacon transmitter 4 and the portable terminal 5 from the “reception field strength value” (S52). The data analysis server 3 counts how many portable terminals 5 exist within a certain distance of the specific beacon ID (S53). That is, the data analysis server 3 estimates the number of workers 99 working on the work target 90 based on the received electric field strength.

  FIG. 6 is a chart showing the dangerous motion determination process (S60). As a premise, data related to the portable terminal 5 is accumulated in the data accumulation database 2 by the received data accumulation process (S30) from the portable terminal 5 of FIG. The data analysis server 3 extracts the stored data, here “mobile terminal ID” and “mobile terminal acceleration sensor value” from the data storage database 2 (S61). The data analysis server 3 estimates the movement of the worker 99 from the extracted “mobile terminal acceleration sensor value” (S62), and determines whether or not the work corresponding to the dangerous motion pattern determination model described below is being performed. (S63).

  FIG. 7 is a chart showing the dangerous motion pattern learning process (S70). As a premise, data related to the portable terminal 5 is accumulated in the data accumulation database 2 by the received data accumulation process (S30) from the portable terminal 5 of FIG. The data analysis server 3 extracts a plurality of stored data, in particular, a mobile terminal acceleration sensor value at the time of dangerous motion from the data storage database 2 (S71), performs machine learning using those values (S72), and performs a dangerous motion pattern determination model. Is stored in the data storage database 2 (S73). Here, the dangerous action is an action of lifting and carrying the work object 90, an action of moving up and down the ladder as the work object 90, or a work action using the work object. The mobile terminal acceleration sensor value at the time of dangerous operation is obtained by the process described later in FIG.

  FIG. 8 is a chart showing the dangerous work occurrence notification process (S80). The data analysis server 3 periodically repeats the following series of processes to monitor whether the worker 99 is working safely. Note that the example of FIG. 8 is a determination process for the work object 90 in consideration of the value of the acceleration sensor in the table. In the determination process for the work object 90 that does not consider the value of the acceleration sensor, the processes of steps S81 and S82 described later are not performed.

  Specifically, the data analysis server 3 performs a beacon movement determination process (S40) in FIG. 4 or a movement determination process based on the acceleration sensor information of the beacon transmitter 4 received from the mobile terminal 5 in FIG. It is determined whether the beacon transmitter 4 attached to the object 90) is moving (S81). When it is determined that there is a movement (Yes in S82), the data analysis server 3 performs the dangerous motion determination process (S60) in FIG. 6 and determines whether it matches the pattern of “dangerous work” (S83). When it is determined that there is no movement (No in S82), the data analysis server 3 returns to the top of the process and is repeated periodically.

  If it is determined that the work is dangerous (Yes in S84), the data analysis server 3 performs the beacon periphery number determination process (S50) of FIG. It is determined whether there are any persons (S85). When it is determined that there is no specified number of persons (No in S86), the data analysis server 3 determines that a dangerous work is being performed, and issues a report (e-mail, indicator lamp lighting, etc.) (S87). If it is determined that there is a specified number of people (Yes in S86), the data analysis server 3 determines that no dangerous work is being performed, returns to the top of the process, and repeats it periodically.

  FIG. 9 is a chart showing the dangerous work post-check process (S90). In this process, when the worker 99 performs some work on the work object 90 to which the beacon transmitter 4 is attached, it is checked afterwards whether or not the work at the work time is appropriate. .

  The data analysis server 3 acquires work time data from the data storage database 2 (S91), and whether or not the beacon transmitter 4 attached to the work object 90 is moving by the beacon movement determination process (S40) of FIG. Is determined (S92).

  When it is determined that there is a movement (Yes in S93), the data analysis server 3 performs the dangerous motion determination process (S60) in FIG. 6 and determines whether the pattern matches the “dangerous work” pattern (S94). When it is determined that there is no movement (No in S93), the process ends.

  When it is determined that the dangerous work is in the dangerous motion determination process (S60, S94), the data analysis server 3 performs the beacon periphery number determination process (S50) in FIG. ) Is determined (S96).

  When it is determined that there is no specified number of persons (No in S97), the data analysis server 3 determines that the work is “dangerous work” (S98). The determination result is stored in the data storage database 2 and can be used in the above-described dangerous motion pattern learning process (S70) of FIG. When it is determined that there is a specified number of people (Yes in S97), the data analysis server 3 uses the trail as “work as specified” (S99).

  As described above, according to the present embodiment, when the worker 99 performs the work on the work object 90, the dangerous work below the specified personnel is detected to alert the worker who is about to perform the dangerous work. Dangerous work can be prevented beforehand. In addition, since it can be checked later whether dangerous work is less than the specified number of people, it can be used as a trail of safe work that is performed by the specified number of people. In addition, there is a psychological deterrent effect on dangerous work with less than the prescribed number of people. If the work is moved while there are fewer than the specified number of people, it is determined that the work is dangerous, and alerts the worker and the supervisor by sending an e-mail notification or an indicator light. Dangerous work can be prevented beforehand. Data when the work is performed is accumulated in the data accumulation database 2 so that it can be checked for violation work and a trail can be used at a later date. The determination of dangerous work is performed by the above-described “beacon transmitter number determination (S50)”, “beacon transmitter movement determination (S40)”, and “dangerous operation determination (S60)”.

  The present invention has been described based on the embodiments. This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to combinations of these components, and such modifications are also within the scope of the present invention.

  In the embodiment described above, it is determined based on the model created by the dangerous action pattern learning process shown in FIG. 7 whether the worker 99 is performing an action corresponding to the dangerous action pattern. However, the data analysis server 3 does not have to make a determination based on the dangerous motion pattern model created by machine learning. For example, when determining whether or not the work object 90 is transported by a plurality of people, It is determined whether or not the acceleration data of the work object 90 and the acceleration data of the worker 99 are similar. If they are similar, it is estimated that the worker 99 is working on the work object 90 and is dangerous. You may determine with corresponding to a work pattern. Also by this, it is possible to obtain the same effect as the above-described embodiment.
