The system server 3 includes a wired communication unit 31, a wide area wireless communication unit 32, a position information storage unit 33, a subject terminal registration unit 34, a state determination unit 35, and an alarm issuing unit 36.

  FIG. 5 shows a configuration example of the local server 4. The local server 4 includes a wired communication unit 41, a wide area wireless communication unit 42, an intra area wireless communication unit 43, a target person terminal registration unit 44, and a state determination unit 45.

Below, the Example using embodiment of this invention is shown in detail.
The target person mobile communication terminal 1 is possessed by a protection target person who is likely to encounter a kidnapping case or get lost, such as an infant, a child, or an elderly person. The target person mobile communication terminal 1 receives the signal transmitted by the absolute position information transmitting means 5 by the absolute position information receiving means 13, and by itself cooperating with the absolute position detecting means 14 alone or the system server 3, Is transmitted to the system server 3 by the wide area wireless communication means 11.

  In general, it is difficult to receive absolute position information such as GPS in a place where the sky cannot be seen indoors. Therefore, when the absolute position cannot be detected, the relative position detecting means 14 equipped with an accelerometer or the like detects the moving direction and moving speed, and transmits the relative position information to the system server 3. Further, when the wide area wireless communication means 11 moves to a place where it cannot be used, the absolute position detected last and its relative position information are continuously stored in its own position information storage means 16, and the wide area wireless communication means 11 When it becomes usable, the stored information is transmitted to the system server 3.

  When communication between the subject mobile communication terminal 1 and the guardian mobile communication terminal 2 is established by the intra-area radio communication means 12 and the intra-area radio communication means 22, the target-guardian communication establishment information is targeted. Either the mobile user communication terminal 1 or the guardian mobile communication terminal 2, or both terminals transmit to the system server 3.

  When the state determination unit 35 of the system server 3 determines that the abnormal state is defined in advance, or the moving speed detected by the relative position detection unit 15 exceeds a preset speed, The target person mobile communication terminal 1 that has been determined to be in an abnormal state by the state determination means 17 because the communication between the target person and the guardian has not been established, uses the in-area wireless communication means 12 or the wide area wireless communication means 11 to issue an alarm issuing means. 18 continues to issue an abnormal condition.

  The guardian mobile communication terminal 2 always tries to establish communication with the subject mobile communication terminal 1 having a preset identifier by the intra-area wireless communication means 12. However, the monitoring of the subject mobile communication terminal 1 can also be set to the system server 3, and in this case, communication with the subject mobile communication terminal is stopped.

  The guardian mobile communication terminal 2 can measure the distance from the subject mobile communication terminal 1 based on the electric field strength, and the target mobile communication can be performed even in a state where communication by the in-area wireless communication means 11 is possible. When the distance to the terminal 1 approaches a preset threshold value or exceeds the threshold value, a warning signal is issued to the system server 3 by the wide area wireless communication means 11 or the intra area wireless communication means 12.

  The guardian mobile communication terminal 2 can receive the position of the subject mobile communication terminal 1 from the system server 3.

  The system server 3 constantly monitors the existence position and the moving speed of the subject mobile communication terminal 1 registered by the guardian mobile communication terminal 2. When the local server 4 is registered as a temporary movement permission area by the guardian mobile communication terminal 2, a cooperative relationship is concluded between the system server 3 and the local server 4 in the set temporary period, and the local server 4 helps. The subject mobile communication terminal 1 is monitored.

  The system server 3 does not receive the target person guardian communication establishment information, and when the target person mobile communication terminal 1 goes out of the normal permission area 6 or the temporary permission area 7, or the target person mobile communication When the moving speed of the terminal 1 exceeds a preset threshold value, it is determined that an incident such as kidnapping has occurred, and a communication is communicated to the guardian mobile communication terminal 2 to determine the treatment. Ask the police or a contracted security company to alert you and seek protection of the subject.

  The local server 4 is installed in a place where it is difficult for the target mobile communication terminal 1 to receive the absolute position information such as GPS, such as an indoor play facility. When designated as a temporary permission area, the identifier of the subject mobile communication terminal is registered in the subject terminal registration means 44.

  The local server 4 always communicates with the registered subject mobile communication terminal 1 by the intra-area wireless communication means 43. When the communication is interrupted, the local server 4 determines that an abnormal state has occurred, and the wired server Using the communication unit 41 or the wide area wireless communication unit 42, an alarm issue request is made to the system server 3.

  When the target person mobile communication terminal 1 that has issued an abnormal condition enters the management area of the local server 4, the local server 4 notifies the system server 3 by the wired communication means 41 or the wide area wireless communication means 42. . Upon receiving the report, the system server 3 contacts the guardian mobile communication terminal 2 and asks for a treatment, or automatically issues an alarm to the police or the contracted security company, Seek protection.

  A plurality of target person mobile communication terminals 1 can be owned by one user. The plurality of terminals communicate with each other by the intra-area wireless communication means 12, and when communication between these terminals is interrupted, both target mobile communication terminals 1 are determined to be in an abnormal state and are sent to the system server. The system server 3 determines that the state is abnormal and issues an alarm. As a result, even if one user terminal is discarded by the kidnapper, it is fully effective.

  When one user owns a plurality of target person mobile communication terminals 1, the second and subsequent target person mobile communication terminals 1 may only have the intra-area wireless communication means 12. In this case, when communication with the second and subsequent target mobile communication terminals 1 is interrupted, it is determined that the first target mobile communication terminal 1 is in an abnormal state and the system server 3 is contacted. To do.

  Similarly, when the terminal is discarded by the kidnapper by adding a temperature sensor to the subject mobile communication terminal 1, the state is when the user terminal is below the set temperature or above the set temperature. The determination unit 17 may determine that the state is abnormal and contact the system server 3.

  The present invention allows a service target person (child or elderly person) to carry a portable mobile communication terminal provided with a wireless communication means, a position detection means, a state determination means, and an alarm issuing means, to provide a guardian mobile communication terminal, a system server By coordinating the local server and the location information transmission means, a support system for early recognition and resolution of lost children and kidnapping cases is provided, and further, kidnapping cases and the like can be prevented in advance.

  According to the present invention, it is possible to constantly monitor the position of the person to be protected. In addition, since the range in which a child or an elderly person usually acts is usually limited, it can be automatically determined that the person has been involved in an incident when he / she has deviated from the preset normal movement permission area.

  In addition, since kidnapping cases are often carried out using cars, even if it is a normal movement permission area, it is automatically detected that it has fallen into an abnormal state in the same way because it is moving at an unexpected speed. Can be judged.

  Even within the normal movement permission area, when moving by means of transportation such as a pick-up bus, it usually moves at an unexpected speed, but the accompanying pick-up person owns the guardian mobile communication terminal The communication between the subject mobile communication terminal and the guardian mobile communication terminal is established by the intra-area wireless communication means, either the subject mobile communication terminal or the guardian mobile communication terminal, or By both notifying the system server, the system server can identify the difference from the abnormal state.

  Furthermore, it is normal for parents and guardians to recognize that children and elderly people move away from the normal permission area and move to another location. It is possible to automatically determine whether or not the subject has moved to an unexpected location. When moving from the normal movement permission area to the temporary permission area, the system server identifies the difference from the abnormal state by holding the guardian mobile communication terminal, as in the case of movement by the shuttle bus. I can do it.

  As described above, the system determines that an abnormal situation such as kidnapping or lost child has occurred using the position and movement speed of the person to be protected, thereby speeding up the time until the occurrence of the abnormal condition is recognized. I can do it. This allows early resolution before the incident becomes serious, and early resolution of the kidnapping case leads to deterring the occurrence of the kidnapping case.
