FIG. 2 is a block diagram illustrating a configuration example of the disaster victim side mobile communication terminal 1. This victim mobile communication terminal 1 communicates directly with the explorer mobile communication terminal 2 possessed by the explorer when the user who became the victim at the time of the disaster wishes to inform the explorer of his / her existence. It is a mobile communication terminal equipped with a function to go and inform the explorer of the presence of the user. Victims side mobile communication terminal 1 includes an operation accepting unit 31 which generates a transmission start signals S ₁ on the basis of the victims of the operation, based on the transmission start signals S _1, the mobile communication terminal in possession of advance exploration's And a transmission unit 35 for transmitting an emergency notification signal for notifying that the disaster victim set in between is in an emergency.

The transmission unit 35 includes a transmission control unit 32, an emergency notification signal transmission unit 33, and a victim information notification signal transmission unit 34. The transmission control unit 32 outputs a control signal to the emergency notification signal transmission unit 33 based on the transmission start signal S ₁ generated by the operation reception unit 31. Thereby, the emergency notification signal transmission part 33 transmits an emergency notification signal. Here, the emergency notification signal is a signal used for notifying the explorer of the presence of the disaster victim. The emergency notification signal is transmitted based on the operation of the operation receiving unit 41 of the disaster victim, and is automatically and repeatedly transmitted at a predetermined interval.

  The emergency notification signal is transmitted using the frequency band of the mobile phone and the lowest frequency band (for example, 800 MHz band in Japan). This is because lowering the frequency band to be used shortens the reach, but increases resistance to obstacles. It should be noted that the emergency notification signal is transmitted with relatively weak power (for example, about 0.2 mW).

The transmission control unit 32 also outputs a control signal to the victim information notification signal transmission unit 34. Thereby, the disaster victim information notification signal transmission unit 34 transmits the disaster victim information notification signal. Here, the disaster victim information notification signal is a signal for notifying the explorer of information related to the disaster victim registered in advance in the disaster victim side mobile communication terminal 1. The victim information notification signal includes, for example, information such as the name and age of the victim and a mobile phone number possessed by the victim. Emergency notification signal is transmitted based on the transmission start signal S _1, then it is automatically transmitted from the victim communication terminal 1 at predetermined intervals. For example, the victim information notification signal is transmitted once every time the emergency notification signal is transmitted a plurality of times. The victim information notification signal is transmitted with a relatively strong power (for example, 2 mW). Because the victim information notification signal has a higher transmission power than the emergency notification signal, reducing the number of transmissions compared to the number of emergency notification signal transmissions reduces power consumption and extends the possible transmission time as much as possible. Like that.

FIG. 3 is a block diagram showing a configuration example of the explorer side mobile communication terminal 2 according to the embodiment of the present invention. Exploration side mobile communication terminal 2, the operation reception unit 41 for generating a reception start signal S ₂ on the basis of the survey's operation, receiver 42 for receiving radio signals from the victim side mobile communication terminal 1, the receiving unit 42 A reception signal analysis unit 45 that analyzes the received radio signal and a display unit 46 that displays the analysis contents of the reception signal analysis unit 45 are provided. The receiving unit 42 includes an emergency notification signal receiving unit 43 that inputs an emergency notification signal from the disaster victim side mobile communication terminal 1 and a disaster victim information notification signal receiving unit 44 that inputs a disaster information notification signal. .

In addition, since the explorer side mobile communication terminal 2 only needs to add a function capable of receiving an emergency notification signal and a victim information notification signal to a normal mobile communication terminal, the software is downloaded to the conventional mobile communication terminal. Can be realized.

  The display unit 46 is configured to display a radio wave level indicating the radio wave intensity of the emergency notification signal analyzed by the received signal analysis unit 45 and information on the victim included in the victim information notification signal.

  Next, operations of the disaster-side mobile communication terminal 1 and the explorer-side mobile communication terminal 2 configured as described above will be described. FIG. 4 is a flowchart showing operations of the disaster victim side mobile communication terminal 1 and the explorer side mobile communication terminal 2.

As shown in FIG. 4, when a disaster victim wants to inform an explorer of his / her presence in a situation where he is trapped in rubble at the time of a disaster, an emergency provided in the disaster victim mobile communication terminal 1 The situation notification signal transmission button 12 is pressed. Thus, the operation reception unit 31 shown in FIG. 2 receives an operation of victims, generates a transmission start signal S _1, and outputs to the transmission unit 35. As a result, the mobile communication terminal 1 on the victim side is activated with a transmission function for transmitting an emergency notification signal (S1). In the disaster-side mobile communication terminal 1 in which the emergency notification signal transmission function is activated, the functions other than the emergency notification signal transmission are stopped (S2). For example, the power supply of hardware other than the wireless control unit and the memory is stopped to reduce battery consumption as much as possible.

When receiving the transmission start signal S ₁ , the transmission control unit 32 outputs a control signal to the emergency notification signal transmission unit 33. The emergency notification signal transmitter 33 transmits an emergency notification signal based on this control signal (S3). The transmission control unit 32 counts the number of times of transmission of the emergency notification signal, and repeats the transmission of the emergency notification signal (S3) at regular intervals until the number of transmissions reaches a predetermined number n (No in step S0). And the transmission control part 32 will reset a count value, and will output a control signal to the disaster victim information notification signal transmission part 34, if the frequency | count of transmission of an emergency notification signal reaches the predetermined number n (in step S0 Yes). . Upon receiving this control signal, the disaster victim information notification signal transmission unit 34 transmits a disaster victim information notification signal (S4). Then, the process returns to step S3. By repeating steps S3, S0, and S4, the disaster victim communication terminal 1 repeats the operation of transmitting the disaster victim information notification signal once every time the emergency notification signal is transmitted n times.

On the other hand, in the searcher-side mobile communication terminal 2, when the searcher starts the search, the search function installed in advance is selected by operating the operation button 20 provided on the terminal. Operation accepting unit 41, based on the exploration's operation, it generates a reception start signal S _2, and outputs to the receiver 42. The receiving unit 42 starts a receiving operation to accept the emergency notification signal. As a result, the search function is activated (S5). While the exploration function is being activated, the searcher-side mobile communication terminal 2 is set to a state specialized for receiving an emergency notification signal. Specifically, the reception frequency is switched so as to be optimal for reception in a frequency band (such as the 800 MHz band in the above example) where an emergency notification signal may be transmitted.

  When the emergency notification signal receiving unit 43 receives the emergency notification signal from the disaster victim side mobile communication terminal 1 in the receiving unit 42 whose reception frequency is adjusted, the received signal analyzing unit 45 displays the received emergency notification signal. To analyze. The received signal analysis unit 45 displays the radio wave level indicating the radio wave intensity of the emergency notification signal received from the disaster victim side mobile communication terminal 1 on the display unit 21 as shown in FIG. 5 (S6).

  In addition, when the exploration-side mobile communication terminal 2 receives the victim information notification signal from the victim-side mobile communication terminal 1, as shown in FIG. Information on the person is displayed on the display unit 21 (S7).

  Further, when the explorer-side mobile communication terminal 2 receives the emergency notification signal and the victim information notification signal from the plurality of disaster-side mobile communication terminals 1, as shown in FIG. Display information about victims along with the radio wave level. For example, on the display unit 21, the disaster victim side mobile communication terminal 1 transmits a non-situation notification signal for each victim by the telephone number of the mobile phone, the name of the victim who is the user, and the operation of the victim. The date and time set in the rescue mode are displayed.

  Next, a disaster victim search method using the disaster victim side mobile communication terminal 1 and the explorer side mobile communication terminal 2 will be described. FIG. 6 is a diagram illustrating a disaster victim search method using the disaster victim side mobile communication terminal 1 and the explorer side mobile communication terminal 2 according to the present embodiment. In this example, two explorers a and b use the mobile communication terminal to explore the victims A and B.

  The searchers a and b are lined up at a place where the search is performed at a predetermined interval, for example, 10 m. Each searcher a, b operates the searcher-side mobile communication terminal 2 to activate a search function installed in the searcher-side mobile communication terminal 2.

  Thereby, the radio wave level of the emergency notification signal received from the disaster victims A and B is displayed on the display unit 21 of the explorer side mobile communication terminal 2 of each of the explorers a and b. For example, if the disaster victim A is located near the searcher a and the disaster victim B is located at a position slightly away from the searcher a, the display unit 21 of the mobile communication terminal of the explorer a displays, for example, “Mr. A” , “Radio wave intensity 3” and “Mr. B, radio wave intensity 2” are displayed.

  On the other hand, since the victim B is located at a position slightly away from the explorer b and the victim A is located far away, the display unit 21 of the mobile communication terminal of the explorer b displays “Mr. A, Information such as “radio wave intensity 1” and “Mr. B, radio wave intensity 1” is displayed.

  Thus, based on the information displayed on the explorer-side mobile communication terminal 2, the explorers a and b can specify the positions of the victims A and B. As the explorers a and b get closer to the victims A and B to be searched, the radio wave level displayed on the display unit 21 becomes larger. You can reach the position of the victims A and B. The mobile communication terminals of the searchers a and b can communicate with each other, and the mobile communication terminal can be configured to estimate the position of the victim based on the victim information and the radio wave level received from each other.

  Further, as shown in FIG. 7, if the above-described exploration method is carried out in an area to be explored in a plane by a larger number of explorers a, b, c, d, the data is sampled at each explorer-side mobile communication terminal 2. Since the radio wave level of the disaster victim side mobile communication terminal 1 can be acquired, the positions of more disaster victims A, B, and C can be specified.

  Thus, according to the disaster victim side mobile communication terminal 1 according to the present embodiment, since the emergency notification signal is transmitted from the disaster victim mobile communication terminal 1 possessed by the disaster victim, Even if the telephone number or the like is not known in advance, the victim can be searched.

  The disaster-side mobile communication terminal 1 only needs to operate at least when an emergency notification signal is transmitted, and the power consumption of the battery is minimized while waiting for the rescue-side mobile communication terminal 1 to be rescued. be able to. Moreover, the operation time of the disaster victim side mobile communication terminal 1 can be further extended by stopping functions other than transmission of an emergency notification signal.

  In addition, by transmitting the disaster victim information as a disaster victim information notification signal from the disaster victim side mobile communication terminal 1, it is possible to identify the disaster victim before the rescue and to make a rescue plan based on the information. it can. For example, when the victim is a weak person such as a child or an elderly person, a rescue plan such as rescue with priority from such a victim can be made.

  Further, since a mobile communication terminal such as a mobile phone terminal is used as the communication device, a dedicated device for specifying the location of the victim is not required. In addition, since the explorer side mobile communication terminal 2 can function as a search side mobile communication terminal by downloading software even in an existing mobile communication terminal, even a mobile communication terminal that does not have a search function in advance. In the event of a disaster, the mobile communication terminal can be easily explored simply by downloading a patch from the center. As a result, since safe people at the disaster site can immediately become explorers after the disaster, the first action time of the rescue operation can be shortened, and the disaster victim can be rescued early.

  It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention.
