Description

  The present invention relates to a search support apparatus, system, method, and program for supporting search for a victim.

  When a distress accident occurs in a place where there is no communication means such as outside the service area of the mobile phone, the distress cannot notify the other person that he / she has suffered even if he / she has a mobile phone. As a result, the victim will either escape on their own or wait until they are discovered by a searcher who has noticed the disaster.

  When the searcher recognizes that a distress accident has occurred, the searcher searches the area assumed to have been lost from the sky, such as a helicopter, or searches on the ground. However, when a searcher boarding a helicopter searches visually from the sky, it is often difficult to find even if there are distressed persons in the search area. In addition, when people search by walking, the location of the distress is identified by many people's investigations, so it is easy to be affected by the weather, time of day, and dangerous places. For this reason, there is a risk of secondary damage, and it often takes time to find a victim.

  For example, FIG. 26 is an image diagram of a search when searching for a victim who has been lost in a mountain. When people search by walking, it is difficult to investigate the part off the road, and it often moves along the road, so it takes a lot of people and time to find the victim.

  As a method of solving such a problem, there is a method of identifying a position of a victim by receiving a signal from a transmitter possessed by the victim, as in a method described in Patent Document 1 to Patent Document 4.

  In the method described in Patent Document 1, a receiver mounted on an unmanned aerial vehicle receives a transmitter's radio wave held by a victim and specifies the position of the victim based on the electric field strength of the radio wave from the transmitter.

  In the method described in Patent Literature 2, the receiver of the search party receives the transmitter's radio wave that the victim has, and specifies the position of the victim based on the reception direction and reception level of the radio wave from the transmitter. .

  In the method described in Patent Document 3, a receiver mounted on a helicopter or the like receives a radio wave of a transmitter held by a victim, and the azimuth, elevation, depression, and GPS (Global Positioning System) of the radio wave from the transmitter is received. ) To determine the location of the victim based on the receiver location information.

  In these methods, since the position of the victim is specified by receiving the radio wave from the transmitter, it is possible to shorten the time until the victim is found.

  However, in the methods described in Patent Documents 1 to 3, the method for specifying the position of the victim is complicated.

  On the other hand, in the method described in Patent Document 4, the rescuer support device installed in a helicopter or the like receives position information from a mobile phone with a GPS function possessed by the victim. Thereby, it becomes possible to identify the position of the victim more easily.

  The configuration example of each device constituting the search support system and the search support system of the present embodiment has been described above. As described above, in this embodiment, the victim has the searched terminal 40 capable of wireless communication by wireless LAN, and the location information of the own apparatus is transmitted from the searched terminal 40 to the search support device 20 via the wireless LAN at the time of the disaster. Send. Then, the search support device 20 transmits the position information of the searched terminal 40 to the search management device 60 via the wireless LAN. As a result, the searcher can know the position of the searched terminal 40.

  In the present embodiment, it is assumed that the search support device 20 is an unmanned small airplane. In this case, the searcher can specify the position of the searched terminal 40 by searching by the search support device 20 and then go to rescue the victim. As a result, it is easy to grasp the situation of the place where the victim is located, and it is possible to cope with the minimum number of people, so that it is possible to suppress the risk of secondary damage such as a searcher's distress or injury.

  FIG. 9 is an image diagram in the case of searching for a victim who has suffered in the mountains with an unmanned small airplane (search support device 20). Compared to the example of FIG. 26, since the unmanned small airplane can move linearly, it is possible to conduct a wide range of surveys in a shorter time than a manual survey, and the possibility of finding a victim early is increased. . Further, before the searcher senses the occurrence of the distress, it is possible to make the search support device 20 circulate a mountain climbing route or the like at any regular predetermined timing. In that case, the possibility of detecting a distress early and finding a distress early is further increased.

  Next, an operation example of the search support system of this embodiment will be described with reference to FIG. Although the illustration of the wireless LAN router 102 is omitted in this figure, it is assumed that the search support device 20 and the search management device 60 communicate via the wireless LAN router 102.

  Assume that a mountain climber becomes a distress and wants to be rescued by the searched terminal 40 that he / she owns, but cannot contact outside the mobile phone service area. Then, the searcher detects the occurrence of the distress from the mountain climbing plan or the like, and starts searching by the search support device 20.

  First, the distress starts the distress rescue application of the searched terminal 40 and sets the mode of the searched terminal 40 to the distress mode (step S201 in FIG. 10). When the searched terminal 40 is set to the distress mode, the search support device 20 searches for radio waves on the wireless LAN of the search support device 20 (step S202). In the distress mode, the searched terminal 40 operates only the distress rescue function in order to keep the battery for a long time until it is rescued.

  The searcher designates a search area to the search management device 60 using the operation terminal 101. Then, the search management device 60 designates a search route to the search support device 20 (step S203). At this time, the search management device 60 may specify a search area for the search support device 20, and the search support device 20 may determine a search route.

  The search support device 20 starts searching for the searched terminal 40 in accordance with the received search route or search area (step S204). The search support apparatus 20 moves autonomously according to a search route or a search area while confirming the position of the self-apparatus by GPS and confirming an obstacle by a camera or a sensor. When the search area is received from the search management device 60, the search support device 20 moves autonomously so as to cover the search area.

  In addition, the search support device 20 transmits connection information to the own device every predetermined time while moving, and confirms that the searched terminal 40 is not connected (step S205). If the search route or search area cannot be connected to the searched terminal 40 even after searching through the search route or search area, the search support device 20 moves the device to a range where radio waves of the wireless LAN router 102 reach, and the search management is performed. Transmit to device 60. Then, the search management device 60 designates a new search route or search area to the search support device 20.

  When the search terminal 40 receives the connection information from the search support device 20 (step S206), the search terminal 40 has found the search support device 20 (step S207), and thus connects to the search support device 20 as a wireless LAN slave unit (step S208). ). When the connection is established, the searched terminal 40 requests access to the search support device 20 (step S209), and the search support device 20 grants access (step S210). Authentication information necessary for connection destination and access permission is registered in advance in the searched terminal 40 and the search support device 20, and the search support device 20 and the searched terminal 40 authenticate using the authentication information. To do. Then, the searched terminal 40 transmits its own position information to the search support device 20 (step S211).

  The search support device 20 that has received the position information of the searched terminal 40 transmits the position information to the search management device 60. When the search support device 20 and the wireless LAN router 102 are separated, the search support device 20 searches for the search management device. The position information cannot be transmitted to the device 60. Therefore, the search support device 20 moves the own device to a place where the position information can be transmitted (step S212). And the search assistance apparatus 20 transmits the positional information on the to-be-searched terminal 40 to the search management apparatus 60 (step S213).

  The search management device 60 that has received the position information of the searched terminal 40 outputs the position information to the display device of the own device and the operation terminal 101 (step S214). In this way, the searcher can grasp the position information of the searched terminal 40 held by the victim.

  In FIG. 11, the image figure of a movement of the search assistance apparatus 20 when the to-be-searched terminal 40 is not found is shown. If the search support device 20 cannot find the searched terminal 40 even after completing the search of the search area or the search route, the search support device 20 moves to the range where the radio wave of the wireless LAN router 102 reaches and cannot find the searched terminal 40. To the search management device 60.

  FIG. 12 shows an image diagram of the movement of the search support device 20 when the searched terminal 40 is found. When the search support device 20 can receive the position information of the searched terminal 40 from the searched terminal 40, the search support device 20 moves to the range where the radio wave of the wireless LAN router 102 reaches and sends the position information of the searched terminal 40 to the search management device 60. Send.

  By operating in this way, the search support device 20 performs wireless communication with the searched terminal 40 and the search management device 60 using a wireless LAN. Further, the position information of the searched terminal 40 is received from the searched terminal 40 via wireless communication, and the position information of the searched terminal 40 is transmitted to the search management device 60 via wireless communication. Therefore, it becomes possible to support the search for the victim by a method with lower power consumption.

  As described above, in the second embodiment of the present invention, the search support device 20 performs wireless communication with the searched terminal 40 and the search management device 60 by the wireless LAN. Further, the position information of the searched terminal 40 is received from the searched terminal 40 via wireless communication, and the position information of the searched terminal 40 is transmitted to the search management device 60 via wireless communication. Thereby, it becomes possible to tell the searcher the position of the searched terminal 40 held by the victim. Further, power consumption can be reduced as compared with the case of using a mobile communication system or satellite communication. Therefore, it becomes possible to support the search for the victim by a method with lower power consumption.
