In the processing shown in FIG. 7, when the communication unit 51 receives notification data transmitted from the notification server 40 or the mail server (step S21), the position detection unit 52 is installed indoors with position information transmitted from a GPS satellite. The position information transmitted from the transmitted transmitter 60 is acquired, and the current position of the portable terminal 50 is detected based on the acquired position information (step S22). The position detection unit 52 outputs information on the detected current position to the determination unit 53A.

  When the communication unit 51 receives the notification data, the determination unit 53A outputs the notification data to the notification history management unit 54. Upon receiving the notification data output from the communication unit 51, the notification history management unit 54 stores the history in the storage unit together with the received notification data (step S23). Further, the determination unit 53A determines whether to notify (display, sound output) notification data to the worker by determining whether or not the current position detected by the position detection unit 52 is a specific region. (Step S24).

  Specifically, the determination unit 53A confirms the rank of the type of operation information included in the notification data. Further, the determination unit 53A confirms the current position of the worker (the portable terminal 50) based on the information on the current position. Then, the determination unit 53A determines whether or not the current position exists in a specific area that restricts the rank of the type of operation information. If the determination unit 53A determines that the current position is in a specific area that restricts the rank of the type of operation information, the determination unit 53A determines not to notify notification data including the type of operation information (NO in step S24). On the other hand, if the determination unit 53A determines that the current position does not exist in the specific area that restricts the rank of the type of operation information, the determination unit 53A determines to notify notification data including the type of operation information (YES in step S24). ).

  When it is determined by the determination unit 53A that notification data is to be notified, the notification processing unit 53B outputs the notification data to the display unit 55 for display. Further, when a peripheral device 56 (for example, a wearable device such as a smart watch) is connected to the portable terminal 50, the notification processing unit 53B outputs and displays notification data on the peripheral device 56 (step S25).

And a notification for restricting notification of the information acquired by the information acquisition units 21 and 30 to the notification unit when the determination unit 53A determines that the current position is the specific area 210, 300, or 400. And a processing unit 53B. According to such a configuration, it is possible to notify necessary information according to the position of the user (worker, administrator, etc.). As a result, the notification of necessary information is not buried in the notification of unnecessary information, and the user is prevented from overlooking the information.

  In the present embodiment, the specific area includes at least the area 210 around the industrial machines 20A and 20B, so that the user can check the status of the industrial machines 20A and 20B near the industrial machines 20A and 20B. In such a case, notification of information can be surely restricted.

  In this embodiment, a plurality of types of specific areas 210, 300, and 400 are set, and when the current position is one of a plurality of types of specific areas, the notification processing unit 53B restricts according to the type of specific area. As a result, it is possible to execute restrictions on notification of detailed information according to the area.

  In the present embodiment, the mobile terminal 50 includes a position acquisition unit 52, a notification processing unit 53B, and a notification unit 55, and the notification processing unit 53B restricts information notification to the notification unit 55. Execute / non-execution of information notification can be switched using a position detection function (such as a GPS function) provided in the portable terminal 50 as a standard.

  Moreover, in this embodiment, the information acquisition parts 21 and 30 are provided with the server 30 connected to the network 100, and the server 30 is based on the notification conditions registered previously, and the information acquired through the network 100 is the portable terminal 50. Information processing unit 34 that transmits information to portable terminal 50 when it is determined that the information needs to be notified. According to such a configuration, it is possible to determine whether the information is necessary for the user in two stages, that is, the information management server 30 (information processing unit 34) and the portable terminal 50. As a result, only information necessary for the user can be notified (notified).

  In the present embodiment, the server 30 includes a terminal registration unit 32 that registers a notification condition for each portable terminal 50, and the terminal registration unit 32 is portable as information that needs to be notified to the portable terminal 50 in the notification condition. Different information can be registered for each terminal 50. According to such a configuration, information necessary for the user can be distributed for each portable terminal 50, and only information necessary for the user can be notified (notified).

  The embodiment has been described above, but the present invention is not limited to the above description, and various modifications can be made without departing from the gist of the present invention.

  For example, in the above embodiment, the peripheral area 210 of the industrial machine 20 is a distance (closeness) area where an operator can confirm the operation of the industrial machine 20. It may be an area that can be seen (for example, an area in the site of the factory 200 in FIG. 3). When the industrial machine 20 cannot be confirmed from the work place 220, the peripheral area 210 may be an area excluding the work place 220 within the site of the factory 200. Further, the peripheral area 210 can be appropriately set according to the work environment of the worker. Moreover, although the case where the 1st-3rd specific area was set as a specific area was demonstrated, it is also possible to set one, two, four or more specific areas.

  Moreover, in the said embodiment, the portable terminal 50 determined the alerting | reporting of information based on the present position. However, the configuration is not limited to such a configuration, and the information processing unit 34 of the information management server 30 may determine the notification of information based on the current position of the mobile terminal 50. In this case, the portable terminal 50 transmits information on the current position detected by the position detection unit 52 to the information management server 30 in advance. For example, the mobile terminal 50 periodically transmits information on the current position detected by the position detection unit 52 to the information management server 30. Alternatively, when the information processing unit 34 receives operation information from the authentication unit 31, it requests the mobile terminal 50 for information on the current position, and acquires information on the current position transmitted from the mobile terminal 50 in response to the request. . A processing unit that acquires information on the current position in the information processing unit 34 is referred to as a “position acquisition unit”. Further, for example, a notification condition (location) as shown in FIG. Then, the information processing unit 34 determines whether to perform information notification (notification) based on the notification condition (location) and the information on the current position. A processing unit that determines whether or not to notify (notify) information in the information processing unit 34 is referred to as a “determination unit”. That is, the “determination unit” in the information processing unit 34 is a processing unit corresponding to the determination unit 53 </ b> A of the mobile terminal 50. Thereafter, the information processing unit 34 restricts the transmission (notification) of information to the portable terminal 50 when it is determined that the information notification (notification) is not performed. A processing unit that restricts transmission (notification) of information in the information processing unit 34 is referred to as a “notification processing unit”. That is, the “notification processing unit” in the information processing unit 34 is a processing unit corresponding to the notification processing unit 53B of the mobile terminal 50.

  In the above embodiment, the notification determination unit 34A determines whether or not to notify information based on the type of information, and the determination unit 53A determines based on the current position of the mobile terminal 50. However, the notification determination unit 34A or the determination unit 53A may determine whether to notify information according to time. For example, since the worker is absent after 10:00 pm, it may be determined that the notification determination unit 34A or the determination unit 53A does not notify the information.
