According to the configuration of the first invention, the search terminal can receive the search request information from the search target terminal. The search request information includes the search target position information. The search target position information is, for example, information indicating the current position of the search target terminal that the search target person has, for example, a distress. The search target position information is information generated by positioning the current position based on a position related signal from a position information satellite, and is information indicating a position specified by latitude and longitude, for example.
For this reason, the search terminal can provide the search target position information specified by, for example, latitude and longitude to the user, for example, the staff of the rescue center.
Thereby, the staff of the above-mentioned rescue center can search the search target person who is a user of the search terminal based on the latitude and longitude indicated in the search target position information.

Then, the search terminal compares the current position of the search target terminal indicated in the search target position information with the current position of the search terminal indicated in the search terminal position information for the staff of the rescue center described above. Information indicating a comparison result between the current position of the search target terminal and the current position of the search terminal can be provided by the position comparison unit.
For this reason, the staff of the rescue center described above can determine whether or not the current position of the rescue center is close to the current position of the search target terminal.

  However, latitude and longitude have a certain width. For this reason, it is difficult to specify the exact position of the search target terminal. For this reason, especially in a place with poor visibility such as a mountain, even if the staff of the above-mentioned rescue center approaches the search target terminal based on the latitude and longitude indicating the current position of the search target terminal, the search target It may take time to discover the search target person who is the user of the terminal.

In this regard, according to the configuration of the first invention, the search terminal transmits an excitation signal to the search target terminal and transmits a response signal from the search target terminal. Receiving means and response signal direction specifying means for specifying the direction of the response signal.
Therefore, the search terminal can provide the user with information indicating the direction in which the search target terminal is located by the response signal receiving means and the response signal direction specifying means.

For this reason, the staff of the above-mentioned rescue center that has already approached the search target terminal can find the search target person of the search target terminal by, for example, walking in the direction in which the search target terminal is located. .
Thereby, the rescue system which can grasp | ascertain the position of a search subject quickly and accurately can be provided.

  According to the second aspect, the object is a search target terminal of a search target person, the search target terminal positioning a current position based on a position related signal from a position information satellite, and the search target terminal.

Therefore, the search target terminal can transmit the search target position information to the search target terminal. Since the search target position information is information obtained by positioning the current position based on the position related signal from the position information satellite, for example, it is information indicating a rough position indicated by latitude and longitude.

  Therefore, when the search target terminal is located in a place with poor visibility, such as in a mountain, for example, a rescue center staff member, for example, a rescue center staff member, at the latitude and longitude indicated in the search target position information. Even if the user moves to the corresponding position, the search target person may not be found. That is, even if the staff of the above-mentioned rescue center has reached the vicinity of the search target terminal, the search target person may not be found.

In this case, if the search target terminal has means for notifying the search terminal of the direction in which the search target terminal is located, the search target person can receive rescue.
In this regard, the search target terminal includes an excitation signal receiving unit that receives an excitation signal from the search terminal, and a response signal transmission unit that transmits a response signal corresponding to the excitation signal to the search terminal.
For this reason, the said search object terminal can provide the information for pinpointing the direction where the said search object terminal is located with respect to the said search terminal.
That is, the search target terminal can provide the search terminal with information for quickly and accurately grasping the position of the search target person.

  According to a third aspect, in the configuration of the second aspect, the search request information includes time information indicating a time when the search target position information is generated.

According to the configuration of the third invention, the search target terminal can transmit the time information together with the search target position information to the search terminal.
For this reason, for example, the staff of the rescue center who is the user of the search terminal considers the exhaustion of the physical strength of the search target person when a long time has elapsed since the time indicated in the time information. In order to rescue in a short time, it is possible to take measures such as increasing the number of rescuers.
That is, the search target terminal can provide information for appropriate search activity to the search terminal.

  According to a fourth aspect of the present invention, there is provided a search terminal for searching for a search target terminal, wherein the search terminal receives search request information including search target position information indicating a current position of the search target terminal.

When the latitude and longitude indicated in the search target position information and the latitude and longitude indicated in the search terminal position information are within the same range, the positions of the search target terminal and the search terminal are close to each other. I can say that.
Then, at this point, if the search terminal can identify the direction in which the search target terminal is located, the staff of the rescue center described above will go to the direction in which the search target terminal is located, for example, on foot. Thus, the search target person can be found.

  As shown in FIG. 9, the rescue terminal 82 stores a rescue request information analysis program 422 in the rescue terminal first storage unit 420. In the rescue request information analysis program 422, the rescue terminal control unit 400 analyzes the rescue request information 158 (or 332), and acquires user information 142 (see FIG. 5) included in the rescue request information 158 (or 332). It is information to do. The rescue terminal 82 stores the acquired user information 142 and the like as the user information 462 and the like in the rescue terminal third storage unit 460 of FIG.

As shown in FIG. 9, the rescue terminal 82 has a search device activation program 424. The search device activation program 424 is information for the rescue terminal control unit 400 to control activation of the rescue terminal GPS device 96 and the tag reader 98 of FIG.
The rescue terminal 82 also has a search device stop program 426. The search device stop program 426 is information for the rescue terminal control unit 400 to control the stop of the rescue terminal GPS device 96 and the tag reader 98 of FIG.

  That is, the rescue terminal control unit 400 can control activation and deactivation of the rescue terminal GPS device 96 and the tag reader 98 based on the search device activation program 424 and the search device stop program 426. For example, the rescue terminal control unit 400 can activate and activate both the rescue terminal GPS device 96 and the tag reader 98 based on the search device activation program 424 and the search device stop program 426, or activate only one of them. Can also be activated.

As shown in FIG. 9, the rescue terminal 82 has a rescue terminal position positioning program 428. The rescue terminal position positioning program 428 is information for the rescue terminal control unit 400 to continuously generate rescue terminal position information 474 indicating the rescue terminal position based on the positioning result of the rescue terminal positioning unit 408.
The rescue terminal control unit 400 stores the generated rescue terminal position information 474 in the rescue terminal third storage unit 460. The rescue terminal position information 474 is updated as needed.
In addition, the rescue terminal control unit 400 generates rescue position error information 476 indicating a positioning error of the rescue terminal position based on the rescue terminal position positioning program 428 and stores the rescue position error information 476 in the rescue terminal third storage unit 460.

  The rescue terminal 82 also has a distress location navigation program 430. The distress location navigation program 430 includes map information 452 stored in the rescue terminal second storage unit 450 by the rescue terminal control unit 400, distress location information 468 stored in the rescue terminal third storage unit 460, and rescue. Based on the terminal position information 474, for example, the rescue terminal display unit 404 indicates the direction in which the helicopter 80 of FIG.

  The rescue terminal 82 also has a distress location rescue terminal location confirmation program 432. In the distress position rescue terminal position confirmation program 432, the rescue terminal control unit 400 compares the distress position Z indicated in the distress position information 468 with the position of the rescue terminal indicated in the rescue terminal position information 474, and the distress position Z and the rescue terminal. This is information for confirming whether the positions of 82 match. That is, the distress position rescue terminal position confirmation program 432 and the rescue terminal control unit 400 are examples of position comparison means.

For example, the rescue terminal control unit 400 determines whether the latitude and longitude of the distress position Z and the latitude and longitude of the position of the rescue terminal 82 are within the same range based on the distress position rescue terminal position confirmation program 432. Determine whether. Then, the rescue terminal control unit 400 determines that the latitude and longitude of the distress position Z and the latitude and longitude of the position of the rescue terminal 82 are at least equal to each other in degrees, minutes, and seconds indicating latitude and longitude. For example, it is determined that the latitude and longitude of the distress position Z and the latitude and longitude of the position of the rescue terminal 82 are within the same range. Then, for example, the rescue terminal control unit 400 displays the fact on the rescue terminal display device 92 of FIG. Thereby, the user B of the rescue terminal 82 can search the user A of the distress terminal 20 by turning over the distress position Z (see FIG. 1) with the helicopter 80.
In addition, the rescue terminal control unit 400 may include at least an integer part of degrees, minutes, and seconds among degrees, minutes, and seconds, where the latitude and longitude of the distress position Z and the latitude and longitude of the position of the rescue terminal 82 indicate latitude and longitude. If they match, the latitude and longitude of the distress position Z and the latitude and longitude of the position of the rescue terminal 82 may be determined to be within the same range. Thereby, when there is a high possibility that the distress terminal 20 is located closer to the rescue terminal 82, it can be displayed on the rescue terminal display device 92 of FIG.

However, in places where map information is not sufficient, such as in mountains, only a rough map is displayed, so you have to search for the victim by relying on latitude and longitude information and distinctive landmarks, and it is difficult to search for the former There is.
In particular, as shown in FIG. 1, in the case of being buried in the debris 15 that is a victim, it is difficult to find the former even if the position of the rescue terminal 82 is close to the distress position Z.
Further, there is an error in positioning of the position by the distress terminal GPS device 34 (see FIG. 2) and the rescue terminal GPS device 96 (see FIG. 8). For this reason, even when the latitude and longitude of the distress position Z and the latitude and longitude of the position of the rescue terminal 82 are within the same range, the actual position of the distress terminal 20 and the actual position of the rescue terminal 82 In some cases, the location is far away due to both positioning errors, making it difficult to find the victim.
In this regard, as will be described below, the rescue terminal 82 has a configuration for searching for the position of the distress terminal 20 located nearby.

  That is, when the rescue terminal control unit 400 of FIG. 9 determines that the latitude and longitude of the distress position Z and the latitude and longitude of the position of the rescue terminal 82 are within the same range based on the search device activation program 424. First, the tag reader 98 of FIG. 8 is activated and an excitation signal is transmitted. When the latitude and longitude of the distress position Z and the latitude and longitude of the position of the rescue terminal are within the same range, the positions of the distress terminal 20 and the rescue terminal 82 are close and are the reach distance of the excitation signal. It can be said that it may be within meters (m).

In this case, the excitation signal reaches the RF tag 36 (see FIG. 4) of the distress terminal 20, and the tag reader 98 of the rescue terminal 82 receives the response signal from the RF tag 36 of the distress terminal 20. Since the user information 206 is placed in this response signal, the rescue terminal 82 displays the user information 206 on the rescue terminal display device 92 (see FIG. 8), etc. The name, etc. can be reported to the user B of the rescue terminal. For this reason, the user who knows the name of A in advance has the distress terminal 20 of the distress A within the reach of the response signal of the RF tag 36, and the user of the distress terminal 20 is the search target. You can know that it is the former.
Even if there are a large number of victims other than A, the search target A can be identified from others.

Furthermore, as shown in FIG. 9, the rescue terminal 82 has a tag signal direction confirmation program 434. The tag signal direction confirmation program 434 is information for the rescue terminal control unit 400 to specify the direction of the response signal from the RF tag of the distress terminal 20 of FIG. 1 received by the tag reader 98 of FIG. That is, the tag signal direction confirmation program 434 and the rescue terminal control unit 400 are an example of response signal direction specifying means.
As described above, the tag reader 98 of FIG. 8 is configured to receive only response signals from one direction. The rescue terminal control unit 400 identifies the direction of the response signal received by the tag reader 98 based on the tag signal direction confirmation program 434.
The rescue terminal control unit 400 stores information indicating the direction of the identified response signal in the rescue terminal third storage unit 460 as tag signal direction information 478.

As shown in FIG. 9, the rescue terminal 82 has a tag signal direction display program 436. The tag signal direction display program 436 is information for the rescue terminal control unit 400 to display the tag signal direction information 478 on the rescue terminal display device 92 of FIG. As a result, the user B who is the user of the rescue terminal 82 can know the direction of the position of the distress terminal 20. For this reason, the second party who has already arrived within the reach of the response signal of the RF tag 36 of the distress terminal 20 searches for the direction of the position of the distress terminal 20 indicated by the rescue terminal 82 by walking, for example. Can be found.
Thereby, the position of the former which is a search subject can be grasped quickly and accurately.

  9 starts the tag reader 98 of FIG. 8 based on the search device activation program 424 and stops driving the rescue terminal GPS device 96 of FIG. 8 when an excitation signal is transmitted. . In order to drive the rescue terminal GPS device 96, power is consumed. In particular, when the rescue terminal 82 is a small portable device, the position of the distress terminal 20 can be searched for a long time by reducing the power consumption. In this regard, when the tag reader 98 transmits an excitation signal, the rescue terminal 82 stops driving the rescue terminal GPS device 96, and thus continues to drive the rescue terminal GPS device 96 after transmitting the excitation signal. The power consumption can be reduced as compared with the case of continuing.

  Unlike the present embodiment, the response signal direction specifying means includes, for example, a signal from a speaker (not shown) of the rescue terminal 82 as the rescue terminal 82 approaches the transmission direction of the response signal from the RF tag 36. A configuration in which the ringtone gradually increases may be used.

Also, unlike the present embodiment, the rescue terminal control unit 400 of FIG. 9 has a position of the rescue terminal 82 within the reach range of the response signal from the distress terminal 20 based on the search device activation program 424. When it is determined that the distance is within 50 meters (m), the tag reader 98 in FIG. 8 may be activated to transmit an excitation signal.
Thereby, since the rescue terminal 82 transmits an excitation signal when it is located in the point which can receive a response signal reliably from the distress terminal 20, it can avoid consuming power wastefully.

Further, unlike the present embodiment, the rescue terminal control unit 400 of FIG. 9 is configured such that when the tag reader 98 of FIG. 8 receives a response signal from the distress terminal 20 based on the search device activation program 424, FIG. You may make it stop the drive of the rescue terminal GPS apparatus 96. FIG. Thereby, the drive of the tag reader 98 is continued until a response signal is received from the distress terminal 20. That is, since the position of the distress terminal 20 is continuously searched for by the rescue terminal GPS device 96 or the tag reader 98, it is possible to avoid losing the position of the distress terminal 20.
Thereby, even after receiving the response signal from the distress terminal 20, the power consumption can be reduced and the position of the distress terminal 20 is lost as compared with the case where the rescue terminal GPS device 96 is continuously driven. You can avoid that.

The above is the configuration of the rescue system 10 according to the present embodiment. Hereinafter, an example of the operation will be described mainly using FIGS. 10, 11, 12, and 13.
FIG.10 and FIG.11 is a schematic flowchart which shows the operation example of the rescue system 10 which concerns on this Embodiment.
12 and 13 are schematic diagrams showing the rescue terminal 82 and the like.

  When the distress terminal 20 in FIG. 2 determines that a notification button (not shown) of the distress terminal input device 28 is pressed by the user A (step ST1 in FIG. 10), a power supply device (not shown) of the distress terminal 20 supplies power. Start (step ST2), and based on the signal S1 and the like from the GPS satellite 12a of FIG.

When the distress terminal 20 determines that the position of the distress position has been completed (step ST4 in FIG. 10), the distress terminal 20 generates distress position information 152 (see FIG. 5) indicating the distress position Z in FIG. The data is stored in the storage unit 150 (see FIG. 5) (step ST5). That is, steps ST3 to ST5 are an example of a search target position information generation step.
In step ST5, in addition to the distress location information 152, distress time information 156 (see FIG. 5) indicating the current time as the distress time is generated and stored in the distress terminal third storage unit 150 (see FIG. 5). .

  Subsequently, the distress terminal 20 transmits rescue request information 158 (see FIG. 5) including distress position information 152 and distress time information 156 (step ST6 in FIG. 11). That is, step ST6 is an example of a search request information transmission step.

When the rescue center server 60 in FIG. 1 determines that the rescue request information 158 transmitted in step ST6 described above has been received via the base station 50, the Internet network 55, and the rescue center server 60 (step ST7), The distress location information 152 and distress time information 156 of the distress terminal 20 are displayed on a system screen map (not shown) of the center display device 74 of FIG. 6 (step ST8). As shown in FIG. 11, in step ST7, the rescue center server 60 is always on standby to receive information from the distress terminal 20 or the like.
On the other hand, the rescue center server 60 selects a rescue terminal that satisfies a condition such as close to the position of the distress terminal 20 (step ST9), and selects a rescue terminal 82 that is suitable for the rescue of the user of the distress terminal 20 On the other hand, rescue request information 332 (see FIG. 7) and dispatch request information (not shown) are transmitted (step ST10). The rescue request information 332 includes distress location information and distress time information of the distress terminal 20. The dispatch request information is information for causing the user B to notify the rescue terminal 82 of the dispatch request.

When it is determined that the rescue terminal 82 in FIG. 1 has received the rescue request signal transmitted in step ST10 described above from the rescue center server 60 (step ST11), the rescue terminal 82 is based on the signal S1 from the GPS satellite 12a in FIG. The current position is measured, and rescue terminal position information 474 (see FIG. 9) indicating the current position of the rescue terminal 82 is generated (step ST12). That is, step ST12 is an example of a search terminal location information generation step. As shown in FIG. 11, in step ST11, the rescue terminal 82 is always waiting to receive information from the rescue center server 60 or the like.
Then, the rescue terminal 82 held in FIG. 1B is based on the distress location information 468 (see FIG. 9) and the rescue terminal location information 474 of the distress terminal 20, for example, as shown in FIG. It is mounted on 80 and moves to the distress position Z of the distress terminal 20 (step ST13).

The rescue terminal 82 continuously measures the current position and updates the rescue terminal position information 474. On the other hand, the rescue terminal 82 receives the rescue request information 332 (see FIG. 7) from the distress terminal 20 via the base station 50, the Internet network 55, and the rescue center server 60, and receives the distress location information 468 (see FIG. 9). It has been updated. The rescue terminal 82 can also receive the rescue request information 158 (see FIG. 5) from the rescue terminal 82 without going through the rescue center server 60.
In this way, the rescue terminal 82 goes to the distress position Z while continuously updating the rescue terminal position information 474 and the distress position information 468. For this reason, even if the position of the distress terminal 20 in FIG. 1 is moved by the user A, the distress terminal Z of the distress terminal 20 can be surely reached.

The rescue terminal 82 heading for the distress position Z continuously performs a process of comparing the distress position of the distress terminal 20 indicated by the distress position information 468 and the current position of the rescue terminal 82 indicated by the rescue terminal position information 474 ( Step ST14). That is, step ST14 is an example of a position comparison step. Specifically, in step ST14, the rescue terminal 82 sets the latitude and longitude corresponding to the distress location of the distress terminal 20 indicated in the distress location information 468 and the current location of the rescue terminal 82 indicated in the rescue terminal location information 474. It is determined whether the corresponding latitude and longitude are within the same range.
The range of identity is a range in which the unit of at least degrees and minutes is common, such as latitude and longitude of both positions being, for example, 38 degrees 20 minutes north and 140 degrees 15 minutes east longitude.

The rescue terminal 82 is located above the distress position Z as shown in FIG. 12B, the distress terminal 82 is the distress position of the distress terminal 20 indicated by the distress position information 468, and the rescue indicated by the rescue terminal position information 474. When it is determined that the current position of the terminal 82 is within the range of identity (hereinafter simply referred to as the range of identity), by displaying that both locations are within the range of identity, Notify the user. Here, if the second party finds the user of the distress terminal 20 (step ST15), the rescue terminal 82 goes to rescue as it is, and the rescue terminal 82 is stopped by the second party.
However, as shown in FIG. 12B, even if the rescue terminal 82 is located above the distress position Z, the debris 15 may become an obstacle and the user may not be able to find the user A of the distress terminal 20. .
In this case, since B knows that he has reached the distress terminal 20, in order to search a narrow range in detail, for example, as shown in FIG. 13, the rescue terminal 82 is held and the helicopter Get off the 80 and search for the user A of the distress terminal 20 on foot.

Here, the rescue terminal 82 determines that the distress position of the distress terminal 20 and the current position of the rescue terminal 82 indicated in the rescue terminal position information 474 are within the same range, and is a certain time, for example, 3 If the drive cannot be stopped within a minute, an excitation signal is transmitted from the tag reader 98 of FIG. 8 (step ST16).
The rescue terminal 82 determines that it is within the range of identity, and the current position of the rescue terminal 82 is within the reach range of the response signal from the distress terminal 20, for example, within 50 meters (m). 8 may be activated to transmit an excitation signal. Thereby, since the rescue terminal 82 transmits an excitation signal when it is located in the point which can receive a response signal from the distress terminal 20 reliably, it can avoid consuming power wastefully. It is an example of an excitation signal transmission step. In step ST <b> 16, the rescue terminal 82 switches the search for the distress terminal 20 by the rescue terminal GPS device 96 to the search by the tag reader 98.

If the rescue terminal 82 is located at a distance where the excitation signal can be transmitted to the RF tag 36 of the distress terminal 20 by the search by the rescue terminal GPS device 96 of FIG. 8, the distress terminal 20 receives the excitation signal from the rescue terminal 82. Receive (step ST17). That is, step ST17 is an example of an excitation signal receiving step.
The distress terminal 20 that has received the excitation signal transmits a response signal (step ST18). That is, step ST18 is an example of a response signal transmission step.

Subsequently, the tag reader 98 of the rescue terminal 82 receives a response signal (an example of a response signal reception step). Then, the rescue terminal 82 determines that the response signal has been received (step ST19), and specifies the direction of the response signal (step ST20). This step ST20 is an example of a response signal direction specifying step.
The rescue terminal 82 displays the direction of the identified response signal on the rescue terminal display device 92 of FIG. By searching for the direction of the response signal (step ST21), the second party can find the user A of the distress terminal 20 buried in the debris 15.
