When the mobile phone 110 is powered on by the mobile terminal holder (S101), the control unit 112 of the mobile phone 110 sets the wireless tag I so that the mobile terminal operation type 109 of the wireless tag 101 is set to “general mode”. The / F unit 111 instructs the wireless tag 101 (S102). When the mobile I / F unit 105 receives an instruction from the mobile phone 110, the control unit 104 of the wireless tag 101 sets the mobile terminal operation type 109 of the wireless tag 101 to “general mode” (S103).

FIG. 4 shows a process when the mobile terminal operation type 109 of the mobile terminal device 100 possessed by the rescuer (“searching side”) that is the rescuer side is set to “rescuer mode 1” when the rescue operation is started. An example of a flow is shown.
When the rescuer (“searching side”) starts the rescue operation, he / she operates the input / output unit 117 of the mobile phone 110 of the mobile terminal device 100 possessed by the rescuer to set the mobile terminal operation type 109 of the wireless tag 101 to “rescuer”. An instruction to set “mode 1” is input. When the input / output unit 117 accepts the instruction (S201), the control unit 112 of the mobile phone 110 receives the wireless tag from the wireless tag I / F unit 111 so as to set the mobile terminal operation type 109 to “rescuer mode 1”. 101 is instructed (S202). When the mobile I / F unit 105 receives an instruction from the mobile phone 110, the control unit 104 of the wireless tag 101 sets the mobile terminal operation type 109 of the wireless tag 101 to “rescuer mode 1” (S203).
Accordingly, the mobile terminal operation type 109 of the mobile terminal device 100 possessed by the rescuer (“searching side”) is set to “rescuer mode 1”, and the rescued side (“searched side”) carries the mobile terminal. Since the mobile terminal operation type of the terminal device 100 is set to “general mode”, it is possible to handle both of them separately.

The rewriting of the mobile terminal operation type 109 of the mobile terminal device 100 can also be performed by an instruction from the mobile terminal search device 200. FIG. 5 shows an example of a processing flow for rewriting the mobile terminal type 109 possessed by the rescuer (“searching side”) from the mobile terminal search device 200.
The rescuer ("searching side") sets the wireless tag identification number 108 of the portable terminal device 100 possessed by the rescuer and the portable terminal operation type 109 from the input / output unit 201 of the portable terminal search device 200 to "rescuer mode 1". Enter the instruction to set. The input / output unit 201 of the mobile terminal search device 200 receives the wireless tag identification number and the setting instruction for “rescuer mode 1” (S301). Using the wireless unit 203, the control unit 202 of the mobile terminal search device 200 transmits a mobile terminal operation rewriting instruction including a wireless tag identification number and a setting instruction to “rescuer mode 1” (S302). When the wireless unit 102 of the wireless tag 101 receives the mobile terminal operation rewrite instruction, the control unit 104 of the wireless tag 101 is stored in the wireless tag identification number included in the mobile terminal operation rewrite instruction and the memory 106 of the mobile terminal device 100. The wireless tag identification number 108 is compared (S303). When the wireless tag identification numbers match in step S303 (S303: Yes), the control unit 104 sets the mobile terminal operation type 109 of the wireless tag 101 to “rescuer mode 1”, and the mobile terminal search device indicates that the setting has been made. 200 is notified (S304). When the wireless unit 203 of the mobile terminal searching device 200 receives the notification, the control unit 202 of the mobile terminal searching device 200 stores the wireless tag identification number 108 and the rewriting time measured by the clock unit 208 in the terminal type rewriting information 212. (S305).
On the other hand, when the wireless tag identification numbers do not match in step S303 (S303: No), the control unit 104 of the wireless tag 101 ends the process.

Although explanation using the processing flow is not performed, the mobile terminal operation type of the mobile terminal device 100 possessed by the rescuer (“searching side”) by the same processing flow as in FIG. 4 or FIG. 109 is reset to “general mode”. This assumes a case where after the rescue operation, the rescuer himself encounters a disaster and becomes a rescued side (“searched side”).
In addition, when a secondary disaster is encountered during the rescue operation and the rescue operation is interrupted without being rescued, the mobile terminal device 100 carried by the rescuer (“searched side”) who has encountered the secondary disaster is held. The terminal operation type remains “rescuer mode 1”. For this reason, although not described in FIGS. 4 and 5, when the mobile terminal operation type 109 is set to “rescuer mode 1” or “rescuer mode 2”, a predetermined time (for example, 10 hours) It is desirable to cause the control unit 104 of the wireless tag 101 to automatically rewrite the initial value “general mode” at a predetermined time (for example, midnight at midnight). If the rescue operation continues even after a certain period of time, the rescuer's mobile terminal operation type 108 of the rescuer performing the rescue operation is again set to “rescuer mode 1” or “rescuer mode” according to FIG. 4 or FIG. By setting it to “2”, a continuous rescue operation is possible.

FIG. 6 shows an example of a processing flow for searching for the mobile terminal device 100 possessed by a person who needs rescue using the mobile terminal search device 200.
When a rescuer (“searching side”) starts a search, he / she inputs an instruction to transmit a rescue necessity inquiry signal using the input / output unit 201 of the mobile terminal search device 200. In response to the instruction, the control unit 104 of the mobile terminal search device 200 transmits a primary disaster rescue necessity inquiry signal using the wireless unit 203 (S401). When a secondary disaster occurs and a part of the rescuer ("searching side") who is in search (rescue) becomes involved and rescued ("searched side"), and the search is resumed In step S401, the control unit 104 transmits a secondary disaster rescue necessity inquiry signal.

When the wireless unit 102 of the mobile terminal device 100 possessed by the disaster victim (“searched side”) receives the primary disaster rescue necessity inquiry signal transmitted by the mobile terminal search device 200 in step S401, the wireless tag 101 The control unit 104 determines whether the rescue necessity inquiry signal is a primary disaster rescue necessity inquiry signal or a secondary disaster rescue necessity inquiry signal (S402).
In this case, since it is a “primary disaster rescue necessity inquiry signal” (S402: Yes), the control unit 104 reads the mobile terminal operation type 109 stored in the memory 109, and the mobile terminal operation type 109 is “ It is determined whether or not the “general mode” is set (S403). The control unit 104 ends the process when the mobile terminal operation type 109 is not “general mode”, that is, “rescuer mode 1” (S403: No). When the mobile terminal operation type 109 is “general mode” (S403: Yes), the control unit 104 determines that a rescue necessity inquiry signal (hereinafter, the term “rescue necessity inquiry signal” is a primary disaster relief necessity inquiry signal. And the secondary disaster relief necessity inquiry signal), the wireless tag identification number 108 is set as the response signal and the response signal is transmitted from the wireless unit 103 ( S404). Further, the control unit 104 instructs the mobile phone 110 to sound an alarm (S405).

When the wireless unit 203 of the mobile terminal search device 200 receives the response signal from the wireless tag 101 transmitted in step S405, the control unit 202 of the mobile terminal search device 200 sets the wireless tag identification number 108 from the received response signal. The extracted RFID tag identification number 108 and / or information related to the portable terminal device 100 specified by the RFID tag identification number 108 are displayed on the input / output unit 201 (S407).
Then, the control unit 202 stores in the memory 210 rescue signal detection information 211 including the wireless tag identification number 108 extracted in step S406, the position information measured by the GPS positioning unit 207, and the time measured by the clock unit 208. (S408).

When the mobile phone 110 receives the alarm ringing instruction instructed in step S405, the control unit 112 of the mobile phone 110 controls the alarm ringing unit 115 to make the speaker 116 ring an alarm sound (S409). This alarm sound may be heard by the disaster victim ("searching side"), and the rescuer ("searching side") is nearby. It can be an opportunity to take action and encourage the victims. The alarm sounding in step S409 may be a method of sounding only for a certain time in order to suppress battery consumption, and stopping sounding after a certain time has elapsed.
When the alarm sound ringed in step S409 reaches the mobile terminal search device 200, the sound collected by the sound collection microphone 206 is analyzed by the alarm sound source identification unit 205, and the mobile terminal device 100 possessed by the disaster victim is Then, it is determined whether or not the alarm sound is generated by receiving the rescue necessity inquiry signal (S410). When it is determined that it is not an alarm sound (S410: No). The control unit 202 ends the process. When it is determined that the sound is an alarm sound (S410: Yes), the control unit 202 generates an alarm sound from the mobile terminal device 100, that is, a person who needs rescue (the mobile terminal device 100 to be searched). Information indicating the presence is displayed on the input / output unit 201 (S411). Then, the control unit 202 stores the rescue signal detection information 211 including the position information measured by the GPS positioning unit 207 and the time measured by the clock unit 208 in the memory 210 (S412). However, since there is no information on the RFID tag identification number 108 that identifies the mobile terminal device 100 that is sounding the alarm sound, the RFID tag identification number 108 is not stored in step S412.

Although not described in the present embodiment, it is desirable to use the information stored in step S408 or S412 as information for notifying the disaster management center using some means and overseeing the entire rescue operation. . In addition, information for identifying an individual from the RFID tag identification number 108, for example, the name of the owner or a mobile phone number may be stored in another strictly managed dedicated server.
When the presence of the victim is found out in step S408 or S412, the rescue operation is started. For rescue, it is necessary to specify the location, but the content depends on the performance and specifications of the antenna of the wireless tag 101 and the portable terminal searching device 200 to be mounted, and does not affect the essence of the present invention. I will omit the explanation. A number of existing techniques for narrowing down the search range based on the reach of radio waves, the use of directional antennas, the strength of received radio waves, etc. have been reported.

Disaster rescue activities are always next to secondary disasters, and rescuers (“searchers”) themselves may be involved in disasters due to secondary disasters such as aftershocks and avalanches during rescue activities. The initial state of the mobile terminal operation type is “general mode” which is “searched side”. When involved in a secondary disaster, the mobile terminal operation type 109 of the mobile terminal device 100 possessed by the person who was rescued (searching side) is normally set to “rescuer mode 1”.
In response to the primary disaster rescue necessity inquiry signal, when the mobile terminal operation type stored in the wireless tag is “general mode”, the mobile terminal 100 operates as “searched side”. In response to the secondary disaster rescue necessity inquiry signal, when the mobile terminal operation type stored in the wireless tag is “general mode” and “rescuer mode 1”, the mobile terminal 100 is “searched side”. Works as.

When the search activity after the disaster occurs, the mobile terminal operation type of the mobile terminal device 100 possessed by the rescuer who is searching is changed to “rescuer mode 1” which is “search side”, and the search activity is started. The search operation is performed by transmitting a primary disaster rescue necessity inquiry signal from the terminal search device 200.
If a secondary disaster occurs during a search activity and a person who has been involved in the search is involved in the disaster, a detailed explanation is omitted, but a new rescuer ("searcher") or a rescue that continues to search The person sets the portable terminal operation type 109 of the portable terminal device 100 to “rescue person mode 2” which is the “searching side” after the occurrence of the secondary disaster by the same processing as in FIG. 4 or FIG. Then resume the search. After the restart, the search operation is performed by transmitting a secondary disaster rescue necessity inquiry signal from the mobile terminal search device 200.
The mobile terminal operation type of the mobile terminal device 100 possessed by the person who has encountered the secondary disaster and has been searching for is still “rescuer mode 1”, and the “secondary disaster rescue necessity inquiry signal” is displayed. On the other hand, it operates as a “searched side”.

In the search after the occurrence of the secondary disaster, a “secondary disaster rescue necessity inquiry signal” is set as the rescue necessity inquiry signal set in step S 401 and transmitted from the antenna 204. The wireless tag 101 of the portable terminal device 100 possessed by the person who has been rescued until now ("searching side") and has encountered a secondary disaster ("searched side") In step S402, the control unit 104 determines that it is not the “primary disaster rescue necessity inquiry signal”, that is, the “secondary disaster rescue necessity inquiry signal” (S402: No).
Then, the control unit 104 reads the mobile terminal operation type 109 stored in the memory 109, and determines whether or not the mobile terminal operation type 109 is “rescuer mode 2” (S403). When the mobile terminal operation type 109 is “rescuer mode 2” (S403: Yes), the control unit 104 ends the process. When the mobile terminal operation type 109 is “general mode” or “rescuer mode 1” (S413: No), the control unit 104 proceeds to step S404 and receives a rescue necessity inquiry signal from the mobile terminal search device 200. To inform.
As a result, the rescuer “searched side” who has encountered the secondary disaster is “existing” within the range where the new disaster rescuer (“searching side”) can receive the secondary disaster rescue necessity inquiry signal. Can be informed.
In the present embodiment, the occurrence up to the secondary disaster is taken into consideration, but by adding the mobile terminal operation type and the rescue necessity inquiry signal, it is possible to easily cope with the occurrence of the secondary disaster beyond the tertiary disaster.

7 shows that when three persons A, B, and X own the mobile terminal device 100, a primary disaster occurs and X is damaged, and a secondary disaster occurs while A and B are searching. An example of the relationship between the mobile terminal device 100 and the mobile terminal search device 200 for each search stage is shown in the search activity when B who was searching for is damaged.
Prior to the occurrence of a disaster (S501), the mobile terminal operation types 109 of the mobile terminal devices 100 possessed by A, B, and X are all in the “general mode”.
When a primary disaster occurs and X is involved in the primary disaster (S502), a disaster rescue team is formed and rescue operations are started. When A and B are selected as members of the rescue team, “rescuer mode 1” is set in the mobile terminal operation type 109 of the mobile terminal devices 100 of A and B as a rescue preparation after the occurrence of the primary disaster (S503). .
Next, the search operation after the occurrence of the primary disaster is started, and the rescuer A or the rescuer B operates the mobile terminal search device 200 to transmit a primary disaster rescue necessity inquiry signal (S504). The rescue request inquiry signal for primary disaster can be received by the portable terminal device 100 of the rescuer X whose portable terminal operation type 109 is “general mode”.

Assume that a secondary disaster occurs during the search activity, and rescuer B who was searching is involved in the secondary disaster (S505). At this time, the rescuer A who has not been affected by the secondary disaster operates the mobile terminal search device 200 to send a primary disaster rescue necessity inquiry signal to perform search activities after the secondary disaster (part 1). (S506) and the mobile terminal device 100 of the rescuer X whose mobile terminal operation type 109 is “general mode” can receive the primary disaster rescue necessity inquiry signal, but the rescuer suffered from the secondary disaster. There arises a problem that the mobile terminal device 100 of B (“searched side”) cannot receive.
Therefore, as a rescue preparation after the occurrence of the secondary disaster, the mobile terminal operation type 109 of the mobile terminal device 100 of the rescuer A is set to “rescuer mode 2” (S507), and the search activity after the secondary disaster occurs (No. 2) is resumed (S508). When the rescuer A operates the mobile terminal search device 200 and transmits a secondary disaster rescue necessity inquiry signal, the mobile terminal operation type 109 is not only the rescuer X whose mobile terminal operation type 109 is “general mode”. Rescue person B who suffered from a secondary disaster with “rescue person mode 1” (“searched side”) can also receive both, and suffer from a primary disaster within the scope of receiving a secondary disaster rescue request signal X and B, who suffered from the secondary disaster, can inform Rescuer A that both exist.
In the example of FIG. 7, the rescuer A who was not affected can know that a secondary disaster has occurred in step S505. However, when all the rescuers are involved in a secondary disaster, it is necessary to grasp the department that manages the entire search activity, but this is out of the scope of the present invention.

FIG. 11 shows an example of the configuration of the acceleration information 404 managed by the mobile terminal device 400 and the mobile terminal device 500.
The acceleration information 404 includes a collection counter (n) 601 and acceleration (0) to acceleration (n) 606 that are information storage fields indexed by the collection counter (n) 601. The collection counter (n) 601 is initially set to 0 when the “rescuer mode 1” or “rescuer mode 2” is set in the mobile terminal operation type 109 of the mobile terminal device 400 or the mobile terminal device 500.
Although not described in the processing flow, as shown in FIG. 4, in the processing flow for setting the mobile terminal operation type 109 of the mobile terminal device 100 possessed by the rescuer to “rescuer mode 1”, the wireless tag in step S203 After “rescuer mode 1” is set in the mobile terminal operation type 109 of 101, the collection counter (n) 601 is initialized to 0.

After the “rescuer mode 1” is set in the mobile terminal operation type 109, the collection counter (n) 601 is initialized to 0.

FIG. 12 shows an example of a secondary disaster encounter monitoring process for monitoring whether or not a searcher possessing the mobile terminal device 400 or the mobile terminal device 500 has encountered a secondary disaster.
The secondary disaster encounter monitoring process illustrated in FIG. 12 is performed at regular time intervals in the control unit 402 of the mobile terminal device 400 or the control unit 502 of the mobile terminal device 500. In the processing flow of FIG. 12, when acceleration is not detected continuously (for example, “5 times” = “5 minutes” continuously), the person who has been rescued (searching side) has encountered a secondary disaster. To be judged.
When the secondary disaster encounter monitoring process is activated, the control unit 402 or the control unit 502 first determines whether or not the mobile terminal operation type 109 is “general mode” (S601), and the mobile terminal operation type 109 is “general”. In the case of "mode" (S601: Yes), the secondary disaster encounter monitoring process is terminated. If it is determined in step S601 that the mobile terminal operation type 109 is not “general mode”, that is, “rescuer mode 1” or “rescuer mode 2” (S601: No), the control unit 402 or the control unit 502 Then, the collection counter (n) 601 of the acceleration information 404 is extracted (S602), and the acceleration is collected from the acceleration sensor unit 403 (S603). The control unit 402 or the control unit 502 stores the acceleration collected in step S603 in the table indexed by the extracted collection counter (n) 601 (S604), and collects the acceleration information 404 collection counter (n) 601. Is incremented by 1 (S605).

Next, it is determined whether or not the value of the collection counter (n) 601 is “5” or more (S606), and if it is smaller than “5” (S606: No), the secondary disaster encounter monitoring process is terminated. In step S606, it is determined whether or not “5 times” = “5 minutes” has elapsed since the acceleration was started to be collected.
When the value of the collection counter (n) 601 is “5” or more in step S606 (S606: Yes), the control unit 402 or the control unit 502 stores the past five times including the present stored in the acceleration information 404. (N, n-1, n-2, n-3, n-4) are extracted (S607), and it is determined whether or not the five accelerations are all equal to or less than a predetermined threshold value (S608). ). If it is determined in step S608 that any of the five accelerations is greater than the predetermined threshold value, that is, there is some movement (S608: No), the secondary disaster encounter monitoring process is terminated. If it is determined in step S608 that all five accelerations are less than or equal to the predetermined threshold value, that is, there is no movement in all five times (S608: Yes), a person who has been rescued (searching side) encounters a secondary disaster. Therefore, “general mode” is set in the mobile terminal operation type 109 of the wireless tag 401 or the mobile terminal device 500 (S609), and the secondary disaster encounter monitoring process is terminated.
In step S609, the mobile terminal operation type is automatically switched from "rescuer mode 1" or "rescuer mode 2" to "general mode", so that the person who has been searching until now needs rescue (Searched side).

By “acceleration analysis” performed in step S608 of the secondary disaster encounter monitoring process, it takes time for the control unit 402 or the control unit 502 to determine that a person who has been on the search side has encountered a secondary disaster. is necessary.
In the sense of quickly performing a rescue operation after encountering a secondary disaster, the “rescue person mode” of the mobile terminal operation type 109 described in the first embodiment and the “rescue necessity inquiry” transmitted from the mobile terminal search device 200 A combination of the method using multiple signals and the method of automatically determining whether or not a secondary disaster has been encountered using the acceleration sensor shown in the third and fourth embodiments has caused a disaster. A system that can quickly search for people can be constructed.

Note that in the mobile terminal device 100 and the mobile terminal device 400, it is desirable that the alarm ringing unit 115 can operate even when the mobile phone 110 is powered off. This is because a current is directly supplied from the wireless tag battery 107 to the alarm sounding unit 115, and from the mobile phone battery 119 via the wireless tag I / F unit 111 from the mobile phone I / F unit 105. There is a method in which the cellular phone 110 is equipped with a function of turning on the supply of current to 115, both of which can be easily realized.
Similarly, in the mobile terminal device 100 and the mobile terminal device 400, it is desirable that the alarm ringing unit 115 can operate even when the mobile phone battery 119 is dead. This can be easily realized by a method of directly supplying a current from the wireless tag battery 107 to the alarm sounding unit 115.
In addition, the wireless tag battery 107 and the mobile phone battery 119 are not provided separately, but a common battery that supplies current to both the wireless tag 101 (or the wireless tag 401) and the mobile phone 110 is provided, and the mobile phone is provided. When the 110 is not used, the supply of current to the mobile phone 110 may be turned off.

Further, in the mobile terminal device 100 and the mobile terminal device 400, the mobile phone I / F unit 105 and the wireless tag I / F unit 111 can be exchanged by short-range wireless communication such as Bluetooth (registered trademark). It can also be realized as a device independent of the telephone 110. For example, the mobile phone 110 transmits mobile terminal operation type information indicating the mobile terminal operation type 109 to the wireless tag 101 or the wireless tag 401 by short-range wireless communication. The wireless tag 101 or the wireless tag 401 receives the mobile terminal operation type information transmitted by short-range wireless communication, and stores the mobile terminal operation type 108 indicated by the received mobile terminal operation type information in the memory 106. However, in this case, it goes without saying that power supply for the purpose of alarming from the wireless tag battery 107 to the mobile phone 110 cannot be performed.
Further, regarding the wireless tag 101, the wireless tag 401, the wireless tag 301, and the wireless tag 501, a device may be configured by mounting a plurality of wireless tags having different performance and different wireless frequency bands to be used.

  In the above-described embodiment, the mobile terminal search device 200 includes the sound collection microphone 206 and the alarm sound source identification unit 205. However, the mobile terminal search device 200 includes the sound collection microphone 206 and the alarm sound source identification unit 205. You don't have to. Even if the mobile terminal search device 200 does not have the sound collection microphone 206 and the alarm sound source identification unit 205, the rescuer (searching side) knows the presence of the rescue target person by listening to the alarm sound emitted from the mobile terminal device 100. be able to.

  As described above, according to the present invention, in the initial stage of the search activity such as when the rescue is started, the rescuer's portable terminal device is not targeted for the search, and the secondary operation during the rescue operation is performed. When the rescuer himself / herself becomes a rescue subject in a disaster, the mobile terminal device can be targeted for search. In other words, even if both the rescued side (“searched side”) and the rescued side (“searching side”) have portable terminal devices, the rescue side (“searching side”) at the start of the rescue operation By changing the mode setting to “rescuer mode 1” or “rescuer mode 2” for the mobile terminal operation type, the side that is rescued in response to an inquiry from the mobile terminal search device (“searched side”) Since the response can be made only from the portable terminal device set to the “general mode”, it is possible to search only for those who are truly seeking rescue.

Further, since not only responding wirelessly to inquiries from the mobile terminal searching device but also responding with alarm sounds, the possibility of being found by a rescuer increases. Furthermore, since an alarm sound is generated in response to a wireless inquiry signal, even if a third party attempts to identify the owner of the mobile terminal device with malicious intent, the owner and surrounding people can easily be notified of the action. Therefore, the use of the mobile terminal search device with malicious intent can be suppressed.
In addition, by incorporating a mobile phone for daily use and an RFID tag for use in an emergency into a mobile terminal device, it is possible to increase the possibility that the victim has the mobile terminal device when a disaster occurs.
