  Hereinafter, embodiments of an alert notification control program, an alert notification control method, an alert notification control device, and an alert notification control system according to the present invention will be described in detail with reference to the drawings.

(One Example of Alert Notification Control Method According to Embodiment)
FIG. 1 is an explanatory diagram of an example of the alert notification control method according to the embodiment. The alert notification control device 100 is a computer that can communicate with each terminal device 110 of the plurality of terminal devices 110 and can transmit an alert to any one of the terminal devices 110.

  Here, in facilities such as beaches, swimming pools, amusement parks, or parks, safety of people is ensured by controlling the occurrence of accidents and incidents and making it easier to rescue people who have encountered accidents or incidents. It is hoped to do. However, it may be difficult to ensure human safety in facilities such as beaches, pools, amusement parks, or parks.

  For example, it is conceivable that a guardian such as a relative or a caregiver watches over the protection target person so that the protection target person such as a child, an elderly person, a disabled person or a disabled person does not encounter an accident or an incident. However, the more crowded the facility, the easier it is for the guardian to be separated from the guardian, the guardian is approaching a danger area where the guardian is likely to encounter an accident or incident, and the guardian has encountered an accident or incident. It becomes difficult to notice, and it becomes difficult to ensure the safety of the person to be protected.

  In addition, for example, in order to suppress the occurrence of an accident or an incident in a facility or to rescue a person who has encountered an accident or an incident, it is conceivable that a facility staff such as a supervisor or a life saver is arranged. However, if the facility staff is congested, it will be difficult to distinguish between the guardian who is separated from the guardian and the guardian who is with the guardian, and it will be difficult to find the guardian who wants to protect. It is difficult to improve safety well.

  Further, for example, when a terminal device possessed by the person to be protected approaches a dangerous area, an alert may be transmitted to the terminal device possessed by the guardian. However, an alert is transmitted to the terminal device possessed by the guardian whenever the terminal device possessed by the guardian approaches the dangerous area without considering the possibility of the accident or incident of the guardian being encountered. End up.

  For this reason, an alert is sent to the terminal device of the guardian even when the guardian is with the guardian and the guardian is relatively unlikely to encounter an accident or incident, and the guardian This increases the frequency with which alerts are transmitted to the terminal devices. As a result, the guardian is exhausted, and it is difficult for the guardian to ensure the safety of the person to be protected, and it may be difficult to efficiently improve the safety.

  In addition, for example, when the terminal device possessed by the guardian and the terminal device possessed by the person to be protected are separated by a predetermined distance or more, an alert may be transmitted to the terminal device possessed by the guardian. However, without considering the possibility that the person to be protected will encounter an accident or incident, each time the terminal device possessed by the guardian and the terminal device possessed by the person to be protected are separated by a predetermined distance or more, the terminal device possessed by the guardian An alert will be sent.

  For this reason, even when the person to be protected is in a relatively safe place and the possibility that the person to be protected encounters an accident or incident is relatively small, an alert is transmitted to the terminal device possessed by the parent, This increases the frequency with which alerts are transmitted to the terminal devices of the. As a result, the guardian is exhausted, and it is difficult for the guardian to ensure the safety of the person to be protected, and it may be difficult to efficiently improve the safety.

  Therefore, in the present embodiment, by sending an alert to the terminal device 110 possessed by the guardian at a relatively preferable time considering the possibility of the subject of the guardian encountering an accident or incident, it is possible to efficiently secure the safety. An alert notification control method capable of improving the above will be described.

  In the example of FIG. 1, the terminal device 110 is a computer used by a user at a predetermined location 120. The plurality of terminal devices 110 corresponds to a group of users and is a set of terminal devices 110 used by each user belonging to the group. A user is a person at a predetermined place 120. The user is, for example, a guardian or a protection target person at a predetermined place 120.

  A guardian is a person who is required to protect a person to be protected. A person to be protected is a person who is preferably protected from others. For example, the person to be protected is protected from a guardian who belongs to the same group. For example, the person to be protected may be protected from guardians belonging to different groups. The person to be protected is, for example, a child. The person to be protected is, for example, an infant among children. The guardian is, for example, a relative for a child who becomes a protection target person. Specifically, the guardian is preferably an adult among the relatives of the child who becomes the guardian. The guardian may be, for example, a teacher or a childcare worker who leads a child who is a protection target.

  The person to be protected may be an elderly person, for example. The guardian is, for example, a relative of an elderly person who becomes a protection target person. Specifically, the guardian is preferably an adult among the relatives of the elderly who are to be protected. The guardian may be, for example, a caregiver or a nurse who takes care of an elderly person who is to be protected.

  The person to be protected may be, for example, a disabled person or a disabled person. The guardian is, for example, a relative of the victim who becomes a protection target. Specifically, the guardian is preferably an adult among the relatives of the victim who becomes the subject of protection. The guardian may be, for example, a nurse who treats a victim who becomes a protection target.

  The group of users is a family in a predetermined place 120, for example. The group of users may be a group of friends, for example. The group of users may be, for example, a group of the lead person and the lead person in the predetermined place 120. Specifically, the group of users may be a group of caregivers and care recipients.

  The predetermined place 120 is a place where the dangerous area 130 is included. The predetermined place 120 may be indoors or outdoors, for example. The predetermined place 120 is, for example, a facility such as a beach or a swimming pool. The predetermined place 120 may be a facility such as an amusement park, a park, or a campsite, for example. The predetermined place 120 may be a facility such as a nursery school, a kindergarten, or a hospital, for example. The predetermined place 120 may be, for example, a road, a mountain, or a ship.

  The dangerous area 130 is an area in the predetermined place 120 where the possibility that the person to be protected will encounter an accident or an incident is relatively high. The dangerous area 130 is, for example, an area designated as a swimming ban by a beach manager and an area with a rocky area with poor scaffolding. The dangerous area 130 is, for example, a pool deeper than the height of a child to be protected in a pool area, a pool in which a water flow is artificially generated, or the like. The dangerous area 130 may be, for example, an area in a pool area where management facilities that are set off by an administrator of the pool area are installed.

  The dangerous area 130 includes, for example, an amusement park, a park, a campsite, and the like, an area around the water area, an area where management facilities set off by the facility manager are installed, bees, snakes, etc. Such as the area around the cliff. The dangerous area 130 is an area having a step such as a staircase in a facility such as a nursery school, a kindergarten, or a hospital. The predetermined location 120 may include a dangerous area 130 that varies depending on a time zone. The dangerous area 130 may be, for example, a road with a relatively large traffic volume. The predetermined place 120 may include, for example, an area that is treated as the danger area 130 in a time zone when the sun goes down or in a time zone when the lights are turned off.

  In FIG. 1, the alert notification control device 100 acquires position information from each terminal device 110 of the plurality of terminal devices 110. The plurality of terminal devices 110 include a first terminal device 110 and a second terminal device 110. The first terminal device 110 is, for example, the terminal device 110 used by a guardian. The 2nd terminal device 110 is the terminal device 110 used by the protection subject, for example.

  For example, the terminal device 110 periodically transmits, to the alert notification control device 100, the position information of the own device acquired based on a signal received from a GPS (Global Positioning System) artificial satellite. For example, the alert notification control apparatus 100 periodically receives position information from each terminal apparatus 110. According to this, the alert notification control apparatus 100 can acquire information used for evaluating the magnitude of the possibility that the person to be protected will encounter an accident or incident.

  Next, it is assumed that the alert notification control device 100 detects the distance between the first terminal device 110 and the second terminal device 110 based on the acquired position information. It is assumed that the alert notification control device 100 detects that the second terminal device 110 has approached the dangerous area 130 based on the acquired position information.

  Then, the alert notification control apparatus 100 detects the first terminal device 110 by detecting that the second terminal device 110 has approached the dangerous area 130 according to the distance between the first terminal device 110 and the second terminal device 110. Whether or not to send an alert to the terminal device 110 is controlled. The alert includes, for example, a notification indicating that the second terminal device 110 has approached the dangerous area 130. The alert may include, for example, information indicating characteristics of a person to be protected who uses the second terminal device 110. For example, the alert may include position information of the second terminal device 110.

  For example, in the case of FIG. 1A, the alert notification control device 100 does not transmit an alert to the first terminal device 110. Specifically, the alert notification control apparatus 100 is based on the first terminal apparatus 110, the second terminal apparatus 110, and the second terminal apparatus 110 based on the position information of the first terminal apparatus 110 and the position information of the second terminal apparatus 110. Detect the distance between. Further, the alert notification control device 100 detects that the second terminal device 110 has approached the dangerous area 130 based on the position information of the second terminal device 110. Then, when the distance between the first terminal device 110 and the second terminal device 110 is less than the threshold, the alert notification control device 100 detects that the second terminal device 110 has approached the dangerous area 130. The transmission of the alert to the first terminal device 110 is not executed.

  Here, when the distance between the first terminal device 110 and the second terminal device 110 is less than the threshold and the second terminal device 110 approaches the danger area 130, the guardian is to be protected. It is possible that the person is watching over the person. In other words, in this case, it is considered that the possibility of encountering an accident or incident is relatively small even if the person to be protected approaches the dangerous area 130. For this reason, the alert notification control apparatus 100 can suppress the alert from being transmitted to the first terminal apparatus 110 when it is not preferable to transmit the alert to the first terminal apparatus 110.

  For example, in the case of FIG. 1B, the alert notification control apparatus 100 transmits an alert to the first terminal apparatus 110. Specifically, the alert notification control apparatus 100 is based on the first terminal apparatus 110, the second terminal apparatus 110, and the second terminal apparatus 110 based on the position information of the first terminal apparatus 110 and the position information of the second terminal apparatus 110. Detect the distance between. Further, the alert notification control device 100 detects that the second terminal device 110 has approached the dangerous area 130 based on the position information of the second terminal device 110. Then, when the distance between the first terminal device 110 and the second terminal device 110 is equal to or greater than the threshold, the alert notification control device 100 detects that the second terminal device 110 has approached the dangerous area 130. The transmission of the alert to the first terminal device 110 is executed.

  Here, if the distance between the first terminal device 110 and the second terminal device 110 is equal to or greater than the threshold and the second terminal device 110 approaches the danger area 130, the person to be protected is protected. It is conceivable that the person is away from the person and is approaching the dangerous area 130. In other words, in this case, it is considered that there is a relatively high possibility that the person to be protected will encounter an accident or incident. For this reason, the alert notification control apparatus 100 can make it easy to ensure the safety of the protection target person by transmitting an alert to the first terminal apparatus 110.

  Thereby, the alert notification control device 100 can transmit an alert to the terminal device 110 possessed by the guardian at a relatively preferable time considering the possibility of the accident or incident of the guardian being encountered. It is possible to improve safety well. For example, the alert notification control apparatus 100 can cause the guardian to know that the person to be protected is likely to be away from the guardian and approach the dangerous area 130, and can improve safety.

  Here, for example, as described above, every time the second terminal device 110 approaches the danger area 130 without considering the possibility of the protection target person encountering an accident or an incident, the first terminal device 110 is contacted. An alert may be sent. In this case, there is a possibility that an alert is transmitted to the terminal device 110 owned by the guardian even when the guardian is together with the guardian and the guardian is relatively unlikely to encounter an accident or incident. There is. As a result, the guardian may be exhausted. In addition, the guardian may neglect the alert. In addition, the guardian may set the first terminal device 110 not to receive the alert.

  On the other hand, the alert notification control apparatus 100 can suppress the transmission of the alert to the first terminal apparatus 110 when it is not preferable to transmit the alert to the first terminal apparatus 110, for example. As a result, the alert notification control device 100 can make it difficult for the guardian to be exhausted. Moreover, the alert notification control apparatus 100 can make it easy for the guardian to trust the alert. Further, the alert notification control device 100 can make it easier for a guardian to use the first terminal device 110. Moreover, the alert notification control apparatus 100 can reduce the communication amount between the own apparatus and the first terminal apparatus 110. Further, the alert notification control device 100 can reduce the power consumption of the first terminal device 110.

  Here, for example, as described above, each time the first terminal device 110 and the second terminal device 110 are separated from each other by a predetermined distance without considering the magnitude of the possibility that the person to be protected encounters an accident or incident, A case where an alert is transmitted to the first terminal device 110 is considered. In this case, there is a possibility that the alert is transmitted to the first terminal device 110 even when the protection target person is in a relatively safe place and the protection target person has a relatively low possibility of encountering an accident or incident. is there. As a result, the guardian may be exhausted. In addition, the guardian may neglect the alert. In addition, the guardian may set the first terminal device 110 not to receive the alert.

  On the other hand, the alert notification control apparatus 100 can suppress the transmission of the alert to the first terminal apparatus 110 when it is not preferable to transmit the alert to the first terminal apparatus 110, for example. As a result, the alert notification control device 100 can make it difficult for the guardian to be exhausted. Moreover, the alert notification control apparatus 100 can make it easy for the guardian to trust the alert. Further, the alert notification control device 100 can make it easier for a guardian to use the first terminal device 110. Moreover, the alert notification control apparatus 100 can reduce the communication amount between the own apparatus and the first terminal apparatus 110. Further, the alert notification control device 100 can reduce the power consumption of the first terminal device 110.

  Here, a case has been described in which the alert notification control device 100 controls whether or not to transmit an alert to the first terminal device 110 by detecting that the second terminal device 110 has approached the dangerous area 130. Not limited to this. For example, the alert notification control apparatus 100 may control whether or not to transmit an alert to the second terminal apparatus 110 when it is detected that the second terminal apparatus 110 has approached the dangerous area 130.

  Further, for example, the alert notification control device 100 transmits an alert to the third terminal device 110 that is not included in the plurality of terminal devices 110 due to the detection that the second terminal device 110 has approached the dangerous area 130. It may be controlled whether or not. The 3rd terminal device 110 is a computer used by the monitoring person arrange | positioned at the predetermined place 120, for example. The third terminal device 110 may be, for example, a computer used by a user who belongs to a user group different from the user group corresponding to the plurality of terminal devices 110.

  Here, although the case where the threshold value compared with the distance between the first terminal device 110 and the second terminal device 110 is one fixed value has been described, the present invention is not limited to this. For example, the threshold value compared with the distance between the first terminal device 110 and the second terminal device 110 may vary. Specifically, a different value may be adopted as the threshold depending on the age of the person to be protected.

  Here, based on the acquired location information of the first terminal device 110 and the location information of the second terminal device 110, the alert notification control device 100 performs the first terminal device 110, the second terminal device 110, Although the case where the distance between these is detected was demonstrated, it is not restricted to this. For example, the first terminal device 110 may detect the distance between the own terminal device and the second terminal device 110. Then, even if the alert notification control device 100 acquires the distance between the first terminal device 110 and the second terminal device 110 detected by the first terminal device 110 from the first terminal device 110. Good. For example, the 2nd terminal device 110 may detect the distance between the 1st terminal device 110 and an own apparatus. And even if the alert notification control apparatus 100 acquires the distance between the 1st terminal device 110 and the 2nd terminal device 110 which the 2nd terminal device 110 detected from the 2nd terminal device 110. Good.

  Here, a case has been described in which the alert notification control device 100 detects that the second terminal device 110 has approached the dangerous area 130 based on the acquired position information of the second terminal device 110. Not exclusively. For example, the first terminal device 110 may detect that the second terminal device 110 has approached the dangerous area 130. Then, the alert notification control device 100 may acquire from the first terminal device 110 a result of detecting that the second terminal device 110 has approached the dangerous area 130. Further, for example, the second terminal device 110 may detect that its own device has approached the dangerous area 130. Then, the alert notification control device 100 may acquire a result of detecting that the second terminal device 110 has approached the dangerous area 130 from the second terminal device 110.

  Here, the case where there is one group of users has been described, but the present invention is not limited to this. For example, there may be a plurality of user groups. The alert notification control apparatus 100 is used by a guardian in a group in consideration of the possibility that a protection target person in the group will encounter an accident or an incident for each group when there are a plurality of user groups. It controls whether or not an alert is transmitted to the first terminal device 110.

Accordingly, the output control unit 904 requests the protector to protect the protector at an early stage in consideration of the possibility of the protector approaching the dangerous area 130 from encountering an accident or incident. It is possible to improve safety.

  For example, when the distance between the first terminal device 110 and the second terminal device 110 is less than the first threshold, the output control unit 904 outputs the first type alert to the first terminal device 110. Do not send Specifically, the output control unit 904 acquires the safety distance “1 m” associated with the group key of the group to which the guardian who uses the first terminal device 110 belongs from the group information table 600.

The eleventh type of alert includes information for notifying an administrator who uses the alert notification control apparatus 100 that it is difficult to ensure the safety of the person to be protected.

  More specifically, the output control unit 904 executes processing for realizing the operation of the alert notification control apparatus 100 described later in FIG. As a result, the output control unit 904 alerts that it is difficult for the guardian to ensure the safety of the guardian based on the number of guardians and the number of guardians within the predetermined range. An administrator who uses the notification control apparatus 100 can be made aware.

  Although the case where the first terminal device 110 is present at the predetermined location 120 has been described here, the present invention is not limited to this. For example, the first terminal device 110 may not exist at the predetermined location 120. Specifically, this is a case where a group of only the protection target person stays at a predetermined place 120. In this case, the alert notification control apparatus 100 may treat the distance between the first terminal apparatus 110 and the second terminal apparatus 110 as ∞.

  Here, although the case where the calculation unit 902 calculates the distance between the first terminal device 110 and the second terminal device 110 has been described, the present invention is not limited thereto. For example, the first terminal device 110 may measure the distance between the first terminal device 110 and the second terminal device 110. In this case, the acquisition unit 901 acquires the distance between the first terminal device 110 and the second terminal device 110 from the first terminal device 110. In this case, the alert notification control apparatus 100 does not have to include the calculation unit 902.

  Further, for example, the second terminal device 110 may measure the distance between the first terminal device 110 and the second terminal device 110. In this case, the acquisition unit 901 acquires the distance between the first terminal device 110 and the second terminal device 110 from the second terminal device 110. In this case, the alert notification control apparatus 100 does not have to include the calculation unit 902.

  Here, a case has been described in which the output control unit 904 determines whether the distance between the first terminal device 110 and the second terminal device 110 is greater than or equal to the first threshold value, but this is not limitative.

For example, the first terminal device 110 detects that the distance between the first terminal device 110 and the second terminal device 110 is equal to or greater than a first threshold, and the detected result is an alert notification control device. 100 may be transmitted.

  Specifically, when the first terminal device 110 becomes unable to perform wireless communication with the second terminal device 110, the distance between the first terminal device 110 and the second terminal device 110 is the first distance. It detects that the threshold value is 1 or more, and transmits the detected result to the alert notification control apparatus 100. In this case, the acquisition unit 901 receives the detection result from the first terminal device 110. In this case, the alert notification control apparatus 100 does not have to include the calculation unit 902.

  Here, the case where the detection unit 903 detects that the second terminal device 110 has approached the dangerous area 130 has been described, but the present invention is not limited thereto. For example, the first terminal device 110 may receive position information of the second terminal device 110 and may detect that the second terminal device 110 has approached the dangerous area 130. In this case, the acquisition unit 901 acquires from the first terminal device 110 the result of detecting that the second terminal device 110 has approached the dangerous area 130. In this case, the alert notification control apparatus 100 may not have the detection unit 903.

  For example, the second terminal device 110 may detect that the second terminal device 110 has approached the dangerous area 130. In this case, the acquisition unit 901 acquires from the second terminal device 110 the result of detecting that the second terminal device 110 has approached the dangerous area 130. In this case, the alert notification control apparatus 100 may not have the detection unit 903.

  In addition, for example, when a Wi-Fi relay device provided in the dangerous area 130 becomes communicable with the second terminal apparatus 110, the second terminal apparatus 110 approaches the dangerous area 130. May be detected. In this case, the acquisition unit 901 acquires a result of detecting that the second terminal apparatus 110 has approached the dangerous area 130 from a Wi-Fi relay device or the like provided in the dangerous area 130. In this case, the alert notification control apparatus 100 may not have the detection unit 903.

(Example of alert notification control system 200)
Next, an embodiment of the alert notification control system 200 will be described with reference to FIGS. First, the description shifts to the description of FIG.

In the example of FIG. 10, the predetermined place is a pool place 1000. The pool 1000 includes “adult pool 1010” and “pool 1020 with waves” as dangerous areas. In addition to the dangerous area, the pool area 1000 includes an “infant pool 1030” and a “rest area 1040”. The pool 1000 has a plurality of users. In the pool 1000, for example, there are user groups G1 to G8. The pool place 1000 may further have a supervisor.

  The users belonging to the group G1 are two guardians and one protection target person. The users belonging to the group G2 are two guardians and three guardians. The users belonging to the group G3 are one guardian and one person to be protected. The users belonging to the group G4 are one guardian and one person to be protected. The users belonging to the group G5 are one guardian and four guardians. The users belonging to the group G6 are two guardians and one protection target person. The user who belongs to the group G7 is one person to be protected. Two users belong to the group G8.

  The current position of the guardian is indicated by, for example, a hatched face mark. Further, the current position of the person to be protected is indicated by, for example, a plain face mark. The current position of the monitor is indicated by a face mark with a hat on, for example. Also, the current positions of users belonging to the same group are displayed connected by line segments.

  Here, the alert notification control apparatus 100 may display the content of FIG. 10 on the display 307, for example. Thereby, the alert notification control apparatus 100 makes it easy for an administrator who uses the alert notification control apparatus 100 to grasp the distribution of users in the pool 1000, and visually grasps which users are in the same group. Can be easier. For this reason, the alert notification control apparatus 100 can make it easy for the administrator who uses the alert notification control apparatus 100 to ensure the safety of the user of the pool 1000.

  Moreover, the alert notification control apparatus 100 may display the same content as FIG. 10 on the touch panel 804 of the supervisor terminal 210, for example. As a result, the alert notification control device 100 makes it easy for the monitor using the monitor terminal 210 to grasp the distribution of users in the pool 1000, and visually grasps which users are in the same group. It can be made easier. For this reason, the alert notification control apparatus 100 can make it easy for the monitor who uses the monitor terminal 210 to ensure the safety of the user of the pool 1000. Next, the description proceeds to FIG.

  FIG. 11 is an explanatory diagram illustrating an example of a situation in which the alert notification control apparatus 100 controls whether or not to transmit an alert. In the example of FIG. 11, the first situation S1 to the fifth situation S5 are shown as an example, and whether or not the alert notification control device 100 transmits an alert to the user terminal 110 used by the guardian in each situation. Will be described.

  The first situation S1 is a situation in which, for example, the protection target person of the group G1 is not near the guardian of the same group G1, and the protection target person of the group G1 is not approaching the dangerous area. In other words, the first situation S1 is that even if the protection target of the group G1 is not close to the danger area, the protection target of the group G1 is not in the vicinity of the protection of the same group G1. There is a relatively high probability of encounter. In the first situation S1, the alert notification control apparatus 100 determines to send an alert to the user terminal 110 used by a guardian of the group G1, for example. The specific operation of the alert notification control device 100 in the first situation S1 will be described later with reference to FIG.

  The second situation S2 is a situation in which, for example, the protection subject of the group G3 is not near the guardian of the same group G3, and the protection subject of the group G3 is approaching the dangerous area. In other words, in the second situation S2, the protection target of the group G3 encounters an accident or incident because the protection target of the group G3 is not near the protection of the same group G3 and is approaching the danger area. It is a situation where the possibility of doing is relatively large. In addition, the second situation S2 is a situation where it is difficult for the guardian of the same group G3 to rescue at an early stage when the protection subject of the group G3 encounters an accident or incident. In the second situation S2, the alert notification control apparatus 100 determines to send an alert to the user terminal 110 used by a guardian of the group G3, for example. The specific operation of the alert notification control device 100 in the second situation S2 will be described later with reference to FIG.

  The third situation S3 is a situation in which, for example, the protection target person of the group G4 is near the guardian of the same group G4, and the protection target person of the group G4 is approaching the dangerous area. In other words, in the third situation S3, even if the protection target of the group G4 is approaching the dangerous area, the protection target of the group G4 encounters an accident or incident because there is a protection of the same group G4 nearby. It is a situation where the possibility of doing is relatively small. In addition, the third situation S3 is a situation in which the guardian of the same group G4 is likely to be rescued at an early stage even if the protection subject of the group G4 encounters an accident or incident. In the third situation S3, for example, the alert notification control apparatus 100 determines not to send an alert to the user terminal 110 used by the guardian of the group G4. The specific operation of the alert notification control device 100 in the third situation S3 will be described later with reference to FIG.

  In the fourth situation S4, for example, the protection target of the group G5 is close to the guardian of the same group G5, the protection target of the group G5 is approaching the dangerous area, and the protection of the group G5 within the predetermined range is performed. It is a situation where the number of persons is more than the number of persons to be protected. In other words, in the fourth situation S4, the guardian of the group G5 within the predetermined range notifies each protection target person of the group G5 within the same range, and ensures the safety of each protection target person. Is a difficult situation. In the fourth situation S4, when a guardian of the group G5 within a predetermined range encounters an accident or an incident at the same time, some of the guardians of the group G5 within the same range encounter each accident It is a difficult situation to rescue. In the fourth situation S4, the alert notification control apparatus 100 determines to send an alert to the user terminal 110 used by the guardian of the group G5, for example. The specific operation of the alert notification control device 100 in the fourth situation S4 will be described later with reference to FIG.

  The fifth situation S5 is a situation in which, for example, the protection target person of the group G7 is approaching the dangerous area, and the protection target person of the group G7 is near the guardians of the different groups G6 and G8. In other words, the fifth situation S5 is similar to the second situation S2, because the protection target person of the group G7 is not near the guardian of the same group G7 and is approaching the dangerous area. There is a relatively high possibility that the person to be protected will encounter an accident or incident. On the other hand, unlike the second situation S2, the fifth situation S5 is a situation in which the guardians of the different groups G6 and G8 can be rescued early if the protection subject of the group G7 encounters an accident or incident. It is. In the fifth situation S5, the alert notification control apparatus 100 determines to send an alert to the user terminal 110 used by the guardians of the groups G6 and G8, for example. The specific operation of the alert notification control apparatus 100 in the fifth situation S5 will be described later with reference to FIG. Next, the description proceeds to FIG.

  FIG. 12 is an explanatory diagram illustrating an operation example of the alert notification control apparatus 100 in the first situation S1. In the example of FIG. 12, (12-1) the alert notification control device 100 acquires position information of each user terminal 110 in the pool place 1000.

  The alert notification control apparatus 100 acquires, for example, the location information of the user terminal 110 used by each of the guardians 1200 and 1201 belonging to the group G1, and the user terminal used by the protection target person 1210 belonging to the group G1.

Further, according to the alert notification control device 100, the guardian and the person to be protected can easily grasp the magnitude of the possibility that the person to be protected encounters the danger, and it is easy to prevent the person to be protected from encountering the danger. Become.

  For this reason, it is a place where a large number of unspecified users gather, such as an amusement park and a pool place 1000, and if a protection target person such as an infant acts alone, there will be many opportunities to encounter dangers such as accidents and incidents. Even in a place, it is easy to ensure the safety of the person to be protected. For example, even if the person to be protected approaches a dangerous area such as an adult pool, the guardian, the manager, or the monitoring person can easily protect the person to be protected at an early stage. In addition, for example, even when the person to be protected encounters an accident or incident in the dangerous area, the guardian, the administrator, or the monitoring person can easily rescue at an early stage.

  In addition, the safety of persons to be protected, such as elderly people, can be easily ensured in nursing facilities. For example, even if the person to be protected approaches a dangerous area such as a staircase, the guardian, the manager, or the monitoring person can easily protect the person to be protected at an early stage. In addition, for example, even when the person to be protected goes out from the back door or the like, which is a dangerous area, the guardian, the manager, or the monitoring person can easily protect the person to be protected at an early stage. In addition, for example, even when the person to be protected encounters an accident or incident in the dangerous area, the guardian, the administrator, or the monitoring person can easily rescue at an early stage.

  17 and 18 are flowcharts showing an example of the control processing procedure. In FIG. 17, the alert notification control device 100 displays a facility map on the display of the terminal device 110 owned by the monitor (step S1701). Next, the alert notification control apparatus 100 displays the dangerous area so as to overlap the displayed facility map (step S1702).

  Moreover, the alert notification control apparatus 100 acquires the user's position information, and displays the current position of the user in an overlapping manner on the displayed facility map based on the user's position information (step S1703). Then, the alert notification control apparatus 100 superimposes and displays a polygon indicating the user group on the displayed facility map (step S1704).

  Next, the alert notification control apparatus 100 compares the position information of the protection target person among the users with the position information of the dangerous area (step S1705). Then, the alert notification control apparatus 100 determines whether or not the protection target person is in the dangerous area based on the comparison result (step S1706). If the user is in the dangerous area (step S1706: YES), the alert notification control apparatus 100 proceeds to the process of step S1801 in FIG.

  On the other hand, when not in the dangerous area (step S1706: No), the alert notification control apparatus 100 compares the position information of the protection target person with the position information of the guardian who belongs to the same group as the protection target person ( Step S1707). Then, the alert notification control apparatus 100 determines whether or not there is a guardian within the alert distance from the protection target person (step S1708). Here, when there is a guardian (step S1708: Yes), the alert notification control apparatus 100 proceeds to the process of step S1701.

  On the other hand, when there is no guardian (step S1708: No), the alert notification control apparatus 100 outputs an alert notification to the terminal device 110 possessed by the guardian who belongs to the same group as the protection target person (step S1709). Moreover, the alert notification control apparatus 100 outputs an alert notification from its own apparatus (step S1710). Moreover, the alert notification control apparatus 100 outputs an alert notification indicating that the person to be protected is alone to the terminal device 110 possessed by the monitor (step S1711). And the alert notification control apparatus 100 transfers to the process of step S1701.

  In step S1801 of FIG. 18, the alert notification control apparatus 100 compares the position information of the protection target person in the dangerous area with the position information of the guardian who belongs to the same group as the protection target person (step S1801). . Then, the alert notification control device 100 determines whether or not there is a guardian within a safe distance from the protection target person (step S1802). Here, when there is no guardian (step S1802: No), the alert notification control apparatus 100 transfers to the process of step S1808.

  On the other hand, when there is a guardian (step S1802: Yes), the alert notification control apparatus 100 determines the number of guardians belonging to the same group as the guardian in the dangerous area and the guardians belonging to the group. The number is compared (step S1803). Then, the alert notification control apparatus 100 determines whether or not the number of protection target persons is smaller than the number of guardians (step S1804). Here, when the number of protection target persons is smaller than the number of guardians (step S1804: Yes), the alert notification control apparatus 100 proceeds to the process of step S1701 in FIG.

  On the other hand, when the number of protection target persons is not smaller than the number of guardians (step S1804: No), the alert notification control device 100 is a terminal device possessed by a guardian who belongs to the same group as the protection target person in the dangerous area An alert notification is output to 110 (step S1805). Moreover, the alert notification control apparatus 100 outputs an alert notification from its own apparatus (step S1806). In addition, the alert notification control apparatus 100 outputs an alert notification indicating that the number of protection target persons is equal to or greater than the number of guardians to the terminal apparatus 110 possessed by the monitor (step S1807). The alert notification control apparatus 100 proceeds to the process of step S1701 in FIG.

  In step S1808, the alert notification control apparatus 100 outputs an alert notification to the terminal device 110 included in the guardian who belongs to the same group as the protection target person in the dangerous area (step S1808). Moreover, the alert notification control apparatus 100 outputs an alert notification from its own apparatus (step S1809). Further, the alert notification control apparatus 100 outputs an alert notification indicating that the protection target person is alone to the terminal device 110 possessed by the monitor (step S1810).

  Next, the alert notification control device 100 belongs to a group different from the protection target person in the dangerous area, and the guard device within the safe distance from the protection target person in the dangerous area has the terminal device 110 of the protection target person. An alert notification indicating a protection support request is output (step S1811). Then, the alert notification control apparatus 100 proceeds to the process of step S1701 in FIG.
