  When a disaster occurs, it is preferable for the victim to transmit information such as their own safety to the outside. However, in the conventional system, although disaster information is notified to the user, there is a problem that the safety of the user cannot be transmitted to the outside from the user side. That is, in the conventional system, no consideration is given to confirming the safety of the user at the time of a disaster.

  Therefore, it is conceivable to simply add a function for the user to send his / her own safety status to the mobile terminal by operating himself / herself. However, in an emergency such as a disaster, the user may forget to operate the mobile terminal. In addition, when a user loses consciousness or cannot move due to a disaster (for example, collapse of a house due to an earthquake), even the operation of the mobile terminal may not be performed. In such a case, there has been a problem that the safety of the user cannot be properly confirmed at the time of a disaster.

Specifically, when the mobile terminal 2 that transmitted the disaster reception signal is not moving, an emergency state in which the user holding the mobile terminal 2 cannot move (for example, collapsed due to an earthquake) It is determined that the house is confined in a house or the like or buried in rubble. In this way, it is possible to grasp the safety state of the user when a disaster occurs.

  In the present embodiment, when a disaster occurs, the user of the mobile terminal 2 inputs his / her safety state (safety state or emergency state) from the input unit 10. When a safety state is input from the input unit 10, a safety confirmation signal is transmitted from the mobile terminal 2 to the center device 3. The center device 3 determines whether or not the user of the mobile terminal 2 is in an emergency state based on whether or not the safety confirmation signal is received. Specifically, when the safety confirmation signal is not received from the mobile terminal 2 that transmitted the disaster reception signal and the movement cannot be confirmed, the user who owns the mobile terminal 2 cannot operate the mobile terminal 2. Such an emergency state (for example, a state of losing consciousness) is determined. In this way, it is possible to grasp the safety state of the user when a disaster occurs.

  Further, in the present embodiment, when a disaster occurs, the current position information of the mobile terminal 2 that has received the earthquake early warning is immediately transmitted to the center device 3. Thereby, the position of the portable terminal 2 when a disaster occurs can be quickly grasped. Therefore, it is possible to immediately grasp the safety state of the user when the disaster occurs.

  In this embodiment, when a disaster occurs, if a safety confirmation signal is not received from the mobile terminal 2 that has transmitted the disaster reception signal, the user who owns the mobile terminal 2 can There is a possibility that it is an emergency state (for example, a state where the user has lost consciousness). In such a case, a position request signal is transmitted from the center apparatus 3 to the mobile terminal 2. The mobile terminal 2 that has received the position request signal acquires current position information and transmits it to the center apparatus 3. Thereby, the position of the portable terminal 2 can be quickly grasped, and the safety state of the user at the time of disaster can be grasped immediately.

  In the present embodiment, when a disaster occurs, if a safety confirmation signal is not received from the mobile terminal 2 that transmitted the disaster reception signal (when safety is not input), the mobile terminal 2 is possessed. The user may be in an emergency state where the user cannot operate the mobile terminal 2 (for example, a state of losing consciousness). In such a case, the ringing unit 14 rings to notify the surroundings. As a result, it is possible to request relief from those around the user.

  The embodiments of the present invention have been described above by way of example, but the scope of the present invention is not limited to these embodiments, and can be changed or modified according to the purpose within the scope of the claims. is there.

  In the above description, the case where the mobile terminal 2 acquires the current position information when receiving the position request signal is exemplified, but the scope of the present invention is not limited to this. For example, the mobile terminal 2 may acquire the current position when receiving the earthquake early warning, and may transmit the current position information together with transmitting the disaster reception signal. In this case, the position acquisition unit 18 acquires the current position information intermittently at intervals of, for example, 1 minute, and transmits the acquired current position information to the center device 3. When the determination of the determination time is completed without receiving a safety confirmation signal from the mobile terminal 2, the state determination unit 31 determines whether the mobile terminal 2 has moved based on the current position information received so far. A safety state (safety state or emergency state) may be determined.

  In the above description, when a disaster reception signal is received from the mobile terminal 2, the case where the safety state of the user is determined based on whether or not the safety confirmation signal is received from the mobile terminal 2 is illustrated. However, the scope of the present invention is not limited to this. For example, when a disaster reception signal is received from the mobile terminal 2, the position request signal may be transmitted to the mobile terminal 2 regardless of whether a safety confirmation signal is received. In that case, based on the current position information sequentially received, whether or not the mobile terminal 2 is moving is monitored during the movement monitoring time, and if the movement cannot be confirmed, the user of the mobile terminal 2 is in an emergency state. You may judge.

  As described above, the safety confirmation system according to the present invention has an effect of being able to grasp the safety state of the user at the time of disaster based on the presence or absence of movement of the mobile terminal possessed by the user, It is useful as a safety confirmation system using a service for distributing earthquake early warnings to mobile terminals.
