In addition to the effects of the described system, rescue operations for the victims can be performed more efficiently.

  FIG. 12 is a block diagram showing still another configuration of a modified example of the victim rescue support system according to the embodiment of the present invention in which the rescue rescue support device is carried by a search party that searches for the victim by walking. .

  The victim rescue support apparatus shown and described in FIG. 2 is incorporated into the system described and illustrated in FIG. 1 and is used by being mounted on a helicopter. The cover area 411 of the victim rescue support apparatus 210 mounted on this helicopter is not infinite because the gain of radio waves is limited. In addition, since the search team on board the helicopter does not know the position of the victim, the antenna directivity of the victim rescue support apparatus 210 cannot be reduced. Will be limited.

  For this reason, in the system illustrated in FIG. 1, unless the distress rescue support apparatus 210 is brought close to a point where the radio waves of the mobile phone 100-1 possessed by the distress 300-1 can be captured, the mobile phone 100-1 When location information cannot be acquired and the victim has slipped into a valley or the like, the helicopter 200 may not be able to approach the point where the radio waves of the mobile phone 100-1 possessed by the victim 300-1 can be captured. There is sex and cannot find a victim.

  The distress rescue support system shown in FIG. 12 is a search team that searches for a victim by walking by downsizing the distress rescue support device shown in FIGS. 1 and 2 into a rescue rescue support device 210-2. 300-2. When searching for a victim by walking, the rescuer support device 210-2 configured in a small size possessed by the search team 300-2 can enter a valley or the like that cannot be reached by the helicopter 200. Then, by bringing the cover area 412 of the small victim rescue support device 210-2 closer to the mobile phone 100-1 possessed by the victim 300-1, and including the mobile phone 100-1 in the cover area 412, The victim rescue support apparatus 210-2 can acquire position information from the mobile phone 100-1 possessed by the victim 300-1.

  The rescue support system for the victims shown in FIG. 12 reduces the size of the rescue support device for the victims, and even if the victims enter a zone that cannot be entered by a helicopter by carrying the search team, Can capture radio waves from mobile phones, and can provide more precise search support.

  In the embodiments of the present invention described above, one of the important points is to accurately specify the position of the victim. As a technology in the prior art that made it possible to specify the position of the victim, the rescue rescue support device that captured the radio wave from the mobile phone held by the victim was a straight line extending from the position of the device to the victim A method has been proposed in which the position of the intersection with the ground surface is specified as the exact position of the victim.

  However, the technique proposed in the prior art has a possibility of erroneously detecting the position of the victim. Therefore, in the embodiments of the present invention described above, the rescuer support apparatus receives the position of the mobile phone of the distress specified by the GPS signal received by the mobile phone of the distress from the mobile phone of the distress. This makes it possible to specify the position of the victim more accurately.

  FIG. 13 is a diagram illustrating a comparison between the method for specifying the position of the victim in the embodiment of the present invention and the method for specifying the position of the victim in the related art described above.

  As shown in FIG. 13, it is assumed that the distress 300-1 is suffering in the mountains. In this case, in the prior art, the rescuer support device 210 mounted on the movable device 200 such as a helicopter captures radio waves from the mobile phone 100-1 possessed by the distress 300-1 and The position of the intersection with the straight ground surface extending in the direction of arrival of the radio wave that seems to be the direction of the victim from the position is the position of the victim.

  However, if the distress 300-1 is distressed in the mountains, the distress rescue support apparatus 210 cannot directly detect the radio wave from the mobile phone 100-1 possessed by the distress 300-1, As indicated by a dotted line in FIG. 13, the radio wave from the mobile phone 100-1 reflected on the mountain is received. As a result, the victim rescue support apparatus 210 is located at the position where the radio wave from the mobile phone 100-1 possessed by the victim 300-1 is reflected, that is, at the position shown as the mobile phone 100-3 in FIG. If the person 300-1 is present, it will be mistakenly recognized.

  On the other hand, in the embodiment of the present invention described above, the cellular phone 100-1 possessed by the victim 300-1 receives a GPS signal from the GPS satellite 400 as shown by a solid line in FIG. , The position information of the terminal is calculated based on the received GPS signal, and the calculated position information of the terminal is transmitted to the victim rescue support apparatus 210. For this reason, the distress rescue support device 210 can receive the position information itself of the mobile phone 100-1 possessed by the distress 300-1 and can acquire accurate position information of the distress 300-1. it can.

  In the method for identifying the position of the victim in the embodiment of the present invention described with reference to FIG. 13, the victim is distressed at a place where his / her mobile phone cannot receive a GPS signal from a GPS satellite. If you do, you will not be able to locate the victim. Therefore, the embodiment of the present invention has a function of continuously receiving GPS signals from already proposed GPS satellites as mobile phones possessed by the victims and automatically storing the calculated position information inside the chip. I will use my mobile phone. By having such a mobile phone possessed by a climber or the like who may have a distress, the position of the distress 300-1 can be specified as a nearby position.

  FIG. 14 is a diagram for explaining a method of specifying a position when a mobile phone owned by a distress is lost in a place where a GPS signal from a GPS satellite cannot be received.

To do. And suppose that the climber was unfortunately lost after moving to the place shown as the distress 300-5 in the position which cannot receive a GPS signal with shields, such as a mountain. In this case, when the distress 300-1 is in a place where the distress 300-1 can receive a GPS signal, the mobile phone 100-1 possessed by the distress 300-1 receives the GPS signal every certain time and calculates position information. The position information is automatically stored in the chip. For this reason, the mobile phone 100-4 possessed by the distress 300-5 who has been lost after moving to a place where a GPS signal cannot be received by a shield such as a mountain stores the position information of the place where the GPS signal was last received. ing. When the mobile phone 100-4 is captured from the victim rescue support device 210, the mobile phone 100-4 transmits position information when the GPS signal was last received to the rescuer rescue support device 210. Thereby, the distress rescue support apparatus 210 receives the position of the mobile phone 100-4 in the vicinity of the distress 300-5 as the position information of the distress, and specifies the position of the distress 300-1. can do.

  According to the above-described embodiment of the present invention, the rescuer support apparatus for the victim is directly using the wireless communication system without transferring the position information of the victim obtained from the mobile phone possessed by the victim to the ground station.
