It becomes possible to do.

=== Regarding the Effectiveness of the Risk Occurrence Information Management System 1 According to this Embodiment ===
As described above, a prevention system that detects that the worker and the heavy machinery have approached each other and prevents the heavy machinery from coming into contact with the worker is considered. In such a system, when it is detected that the worker and the heavy machinery are approaching, attention is drawn by notifying the worker of information that a danger has occurred by using a buzzer or a lamp. In such a case, the worker can take appropriate measures such as avoiding heavy machinery.

  However, if the information other than the worker can be notified, more appropriate countermeasures can be implemented and the usefulness is further increased.

It was decided. Therefore, when a situation (danger) occurs in which the worker P and the heavy equipment 30 approach or contact each other, the position information of the worker P is sent to the management server 70 together with information that the situation (danger) has occurred. Therefore, when such a situation (danger) occurs, it is possible to take a more appropriate countermeasure.

  For example, since the construction manager does not need to check the place where the situation (danger) has occurred, the construction manager can rush to the site even more quickly. Further, as described above, the management server 70 accumulates and manages the position information, so that it is possible to identify an area where danger is likely to occur and to grasp the tendency of the area.

  Moreover, in this Embodiment, the smart phone 50 transmits the terminal ID information of the smart phone 50 with danger occurrence information, the management server 70 receives the danger occurrence information and terminal ID information which the smart phone 50 transmitted, and manages. It was decided to. Therefore, when the situation (danger) where the worker P and the heavy equipment 30 approach or contact each other occurs, the terminal ID information of the smartphone 50 is sent to the management server 70 together with information that the situation (danger) has occurred. Therefore, when such a situation (danger) occurs, it is possible to take a more appropriate countermeasure.

  For example, since the construction manager can immediately identify the worker who has caused the situation (danger), he / she can immediately contact the party, and in what manner of work (work type) It is possible to immediately grasp whether a situation (danger) has occurred. In addition, the management server 70 accumulates and manages the terminal ID information, so that it is possible to identify workers and work modes (work types) that are likely to be in danger, and to grasp these tendencies.

  In the present embodiment, the attachment unit 15 receives the machine ID information of the heavy machine 30 transmitted from the heavy machine 30 and transmits it together with the danger occurrence information when transmitting the risk occurrence information. The danger occurrence information and machine ID information transmitted by the mounting unit 15 are received, the danger occurrence information and machine ID information are transmitted, and the management server 70 receives the danger occurrence information and machine ID information transmitted by the smartphone 50; And we decided to manage it. Therefore, when a situation (danger) in which the worker P and the heavy equipment 30 approach or come into contact with each other, the machine ID information of the heavy equipment 30 is sent to the management server 70 together with information that the situation (danger) has occurred. Therefore, when such a situation (danger) occurs, it is possible to take a more appropriate countermeasure.

  For example, since the construction manager can immediately identify the heavy equipment 30 that has caused the situation (danger), the construction manager can immediately contact the manager and operator of the heavy equipment 30, and what kind of work ( It is possible to immediately grasp whether such a situation (danger) has occurred in (work type). In addition, the management server 70 accumulates and manages the machine ID information, so that it is possible to identify the heavy equipment 30 and the business mode (work type) that are likely to cause danger, and to grasp these tendencies.

=== Other Embodiments ===
The above embodiments are for facilitating the understanding of the present invention, and are not intended to limit the present invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof. In particular, the embodiments described below are also included in the present invention.

  In the said embodiment, although the helmet 10 was mentioned as an example as a wearable thing which attaches the attachment unit 15, it is not limited to this, What kind of thing may be used if it is worn by a human body. Absent. For example, clothes (clothes), gloves, watches, necklaces and the like can be exemplified.

  Moreover, in the said embodiment, although the heavy machinery 30 was mentioned as an example and demonstrated as a construction machine, it is not limited to this. A “construction machine” is a construction machine in a broad sense, and all work machines that perform some kind of work are included in the category of construction machines. Needless to say, a so-called robot is also included regardless of whether it is unmanned or manned.

  Moreover, in the said embodiment, although the smart phone 50 was mentioned as an example and demonstrated as a multifunctional portable terminal, it is not limited to this. For example, the multi-function mobile terminal may be a tablet terminal.

  Moreover, in the said embodiment, although the computer installed in the construction office C was mentioned as an example and demonstrated as the management server 70, it is not limited to this. For example, it may be a computer installed in a central management center of a construction / civil engineering company.

  Moreover, in the said embodiment, as a detection method of danger occurrence, heavy equipment 30 irradiates electromagnetic waves, such as infrared rays, to the predetermined range (irradiation spot) near heavy equipment 30, and it is on wearables, such as helmet 10 of worker P, etc. The method of detecting the occurrence of danger by receiving electromagnetic waves when the attached mounting unit 15 enters the irradiation spot has been described. However, as described above, there are several other methods. May be used (some examples will be described below).

  In the above embodiment, the heavy machine 30 side of the heavy machine 30 and the worker P radiates electromagnetic waves, and the worker P side has a receiving unit, that is, a sensor, but the worker side radiates electromagnetic waves, The heavy equipment side may have a sensor. In this case, when a heavy machine detects the occurrence of a danger, it sends a message to that effect to the worker side mounting unit.

  In the above embodiment, the heavy machinery 30 side and the worker P collaborate to detect the occurrence of danger, but the heavy machinery side alone or only the worker side performs the detection. It is good. For example, the heavy machine (worker) may be provided with a light source and a light receiving element, and the light received from the light source may be reflected by the reflected light reflected by the worker (heavy machine). . In this case, the detection is performed based on the time from when the irradiation light is irradiated until the reflected light is received and the phase difference between the irradiation light and the reflection light. Also in this case, when the heavy equipment detects the occurrence of danger, it transmits that fact to the attachment unit on the operator side. Further, as an example in which detection is performed only on the heavy equipment side (worker side), an example in which detection is performed using a camera is also conceivable.

  Moreover, in the said embodiment, although electromagnetic waves were used for the detection, it is good also as using acoustic waves, such as an ultrasonic wave.

  Moreover, in the said embodiment (henceforth 1st embodiment), the said positional information was decided to be the information which the smart phone 50 acquired by the GPS function. However, it is not limited to this, The example (2nd embodiment) demonstrated below may be sufficient.

  In the second embodiment, unlike the first embodiment, the position information is information acquired by the mounting unit 15 by the GPS function. That is, as shown in FIG. 3, the attachment unit 15 according to the second embodiment has a position information acquisition unit 24 having a GPS function, and the attachment unit control unit 18 controls the position information acquisition unit 24. Then, the position information is acquired, and the attachment unit transmission unit 22 is controlled to transmit the position information to the smartphone 50.

  The smartphone 50 receives the position information in addition to the danger occurrence information and the machine ID information transmitted by the attachment unit 15. That is, the smartphone receiving unit 52 controlled by the smartphone control unit 54 receives the danger occurrence information, the machine ID information, and the position information.

  Then, similarly to the first embodiment, the smartphone 50 (smartphone transmission unit 58) transmits the risk occurrence information, machine ID information, position information, and terminal ID information to the management server 70.

  In the first embodiment, by using the GPS function of the multi-function mobile terminal (smartphone 50), it is possible to omit the installation of the GPS function in the attachment unit 15. Therefore, it is desirable in that the mounting unit 15 is simplified and a cost merit is generated. On the other hand, the second embodiment is useful when the multifunction mobile terminal does not have a GPS function.
