<Outline of the embodiment>
The outline of the embodiment will be described with reference to FIG.
FIG. 1 is a diagram for explaining an overview of a search support system S according to an embodiment. The search support system S according to the embodiment is a system for supporting search of the user U who performs activities that may cause distress, such as mountain climbing and voyage. In order to realize this, the search support system S includes a search support apparatus 1 installed in a place where the search party waiting place R or the search party standby place R can be contacted, and a search support apparatus 1 via the network N. And an action plan management device 2 connected in a communicable manner. Here, the network N is, for example, the Internet or a wireless communication network. Hereinafter, in this specification, the case where the user U is a mountain climber is demonstrated as an example.

  The user U submits the mountain plan digital data to the action plan management apparatus 2 in advance via the network N before climbing. Alternatively, the administrator of the action plan management apparatus 2 stores the contents of the mountain plan submitted by the user U at the climbing entrance in the action plan management apparatus 2. For example, the user U has a device T having at least a function for acquiring positional information such as a smartphone and a function for communicating with the outside, and performs mountain climbing. When the device T is a smartphone, the device T can be connected to the network N via the base station B of the wireless communication network.

  The device T acquires position information indicating the current position of the device T by analyzing the radio wave received from the navigation satellite G. The device T periodically transmits the acquired position information to the search support device 1 via the base station B and the network N. Further, the user U transmits the climbing progress to the search support device 1 using the device T when the user U arrives at a predetermined destination such as a mountain descent or a mountain hut or a campground.

  The search support device 1 acquires the mountain plan of the user U from the action plan management device 2. The search support device 1 determines the time indicated by the mountain plan at the destination indicated in the mountain plan submitted by the user U or the passage place on the way to the destination when communication with the device T has been interrupted for a predetermined period or longer. The flight route of the search flight device 3 is set on condition that the user U has not arrived even after the elapse of the time. The flying device 3 is a small unmanned flying device having a communication function, an imaging function, a voice output function, and the like. The flying device 3 is realized by, for example, a rotary wing aircraft equipped with a plurality of rotors.

  In the search unit waiting place R, one or more flying devices 3 are also waiting in addition to the search unit. In the search support device 1, an example is shown in which N aircraft (N is a natural number) flying devices 3 from the first flying device 3a to the Nth flying device 3n are arranged in the search unit waiting place R. Hereinafter, in the present specification, the first flying device 3a, the second flying device 3b, and the Nth flying device 3n are simply referred to as the flying device 3 unless otherwise distinguished.

  Here, the search support device 1 sets a flight route by giving priority to the distress occurrence points related to the route indicated in the mountain plan among the distress occurrence points in the mountain region indicated in the mountain plan submitted by the user U. To do. Thereby, the search assistance apparatus 1 can make the flight apparatus 3 face in preference to the point with the high probability that the user U is suffering.

<Functional configuration of search support device 1>
FIG. 2 is a diagram schematically illustrating a functional configuration of the search support device 1 according to the embodiment. The search support apparatus 1 according to the embodiment includes a communication unit 10, a storage unit 11, and a control unit 12.

  The communication unit 10 includes, for example, a LAN (Local Area Network) controller. The communication unit 10 transmits and receives data between the action plan management apparatus 2 and the device T via the network N. The storage unit 11 includes a ROM (Read Only Memory) that stores a BIOS (Basic Input Output System) of a computer that implements the search support device 1, a RAM (Random Access Memory) that is a work area of the search support device 1, an OS ( Large-capacity storage such as HDD (Hard Disk Drive) and SSD (Solid State Drive) that store various information including the Operating System), application programs, and the search database 110 and the flying device database 111 that are referred to when executing the application programs Device.

  The control unit 12 is a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit) of the search support device 1, and executes a program stored in the storage unit 11 to execute a plan acquisition unit 120 and a position information acquisition unit. 121, a route setting unit 122, a database management unit 123, and a flying device selection unit 124.

  The plan acquisition unit 120 acquires the mountain plan submitted by the user U who is the search target person from the action plan management device 2 via the network N. The plan acquisition unit 120 stores the mountain plan acquired once from the action plan management device 2 in the storage unit 11. Thereafter, unless the mountain plan is changed by the user U, the plan acquisition unit 120 reads and acquires the mountain plan from the storage unit 11.

  FIG. 3 is a diagram schematically illustrating the data structure of the mountain plan acquired by the plan acquisition unit 120 according to the embodiment. The search support device 1 and the action plan management device 2 allocate and manage a climber ID (IDentification) for uniquely identifying the user U who is a search target person. FIG. 3 illustrates a mountain climbing plan of the user U whose climber ID is UIXXXX.

  As shown in FIG. 3, in the mountain planning, personal information such as the name, age, blood type, mountain climbing experience, and contact information of the user U is associated with the mountain climber ID. Further, in the mountain plan, information related to mountain climbing such as a mountain area where the user U acts, a schedule, a journey, equipment, and the like are also associated with the climber ID. For example, in the mountain plan shown in FIG. 3, a 41-year-old man named O x Taro is scheduled to run from August 18th, 2017 to 21st of the same month, with a climber whose UID is UIDYYYY. It is stored to enter the Kooto Mountains.

  In addition, the search support device 1 and the action plan management device 2 allocate and manage a mountain area ID for uniquely specifying the mountain area to each mountain area. As shown in FIG. 3, the mountain range ID MIDAAAA is assigned to the Kooto Mountain Range.

  Returning to the description of FIG. The location information acquisition unit 121 periodically acquires location information indicating the location of the device T possessed by the user U via the network N. The route setting unit 122 indicates that the user U has not arrived even when a predetermined time has elapsed after the time indicated by the mountain plan in the destination indicated by the mountain plan submitted by the user U or a passing place on the way to the destination. And the flight route of the flight apparatus 3 for search is set on condition that communication with the apparatus T of the user U has been interrupted for a predetermined period or longer.

  Here, the “predetermined time” is a “route setting reference time” to which the route setting unit 122 refers to determine whether or not to set a flight route to be searched by the search flight device 3. is there. As described above, when the user U arrives at a predetermined destination in the mountain plan or a passing place on the way to the destination, the user U transmits the climbing progress to the search support device 1 using the device T. The position information acquisition unit 121 periodically acquires position information from the device T. The route setting unit 122 can determine whether or not the user U has arrived at the destination or passing place based on the position information that the position information acquisition unit 121 periodically acquires from the device T.

  For this reason, if there is no progress report from the user U, there is a high probability that some problem has occurred in the mountain planning. On the other hand, when the user U takes many breaks, a delay of about several hours may occur. Therefore, a specific value of the route setting reference time may be determined according to the difficulty level and season of the mountain area indicated in the mountain plan of the user U, the experience of the user U, and the like, for example, 12 hours. Note that the route setting unit 122 may determine that the location where the radio wave of the wireless communication network has arrived is the location where the user U has arrived, among the destinations and passing locations where the user U has arrived or currencyd.

  The “predetermined period” is a “route setting reference period” to which the route setting unit 122 refers to determine whether or not to set the flight route of the search flight apparatus 3. Even if the user U arrives at the destination or a passing place on the way to the destination according to the mountain plan, the user U may have forgotten to send the climbing progress to the search support device 1. Further, even if the user U cannot reach the destination or the passing place on the way to the destination as the mountain plan, if the position of the device T possessed by the user U is known, the information of the search support device 1 is accessed. The search team that can be confirmed can confirm the safety of the user U.

  On the other hand, if communication with the device T has been interrupted for a predetermined period or longer, the possibility that some problem has occurred in the user U should be considered. In particular, when there is no problem in communication quality on the mountain climbing route shown in the mountain plan of the user U, the probability that some problem has occurred in the user U is increased. Therefore, the specific value of the route setting reference period may be determined in consideration of the communication quality of the mountain area indicated in the mountain plan of the user U, and is, for example, 6 hours.

  The route setting unit 122 gives priority to the distress occurrence point related to the route indicated in the mountain plan by giving the flying device 3 priority by referring to the distress occurrence point in the mountain area indicated in the mountain plan submitted by the user U. Set the flight route to fly. Here, the “distress occurrence point related to the route shown in the mountain plan” means not only the route shown in the mountain plan, but also the point where it is easy to get lost from that route, or when it slips down from that route. It is a point that includes the location of a waterfall such as a fall point or a swamp.

  Since the flying device 3 can move in the air, it can reach the search candidate location more quickly than the search team. The route setting unit 122 sets the flight route that causes the flying device 3 to fly by giving priority to the distress occurrence point related to the route shown in the mountain plan, thereby improving the search efficiency in a place where time is required for manual search. be able to.

  FIG. 4 is a diagram schematically showing the data structure of the search database 110 that stores distress occurrence points and the location of the search team waiting place R in each mountain area. The search database 110 is stored in the storage unit 11 and is managed by the database management unit 123.

  FIG. 4 exemplifies information on the Koto Mountains where the mountain area ID is MIDAAA. As shown in FIG. 4, the search corps waiting place R in the Koto Mountain Range exists at a point indicated by east longitude E1 and north latitude N1. The search database 110 also stores distress occurrence points indicating distress locations that have occurred in the past. FIG. 4 shows that in the Koto Mountain Range where the mountain range ID is MIDAAA, distress occurred at points where the east longitude and the north latitude are specified by E2, N2, E3 and N3, EN and NN, respectively.

  The search database 110 further stores information on the timing and number of past distress occurrences at each distress occurrence point. FIG. 4 is one of distress occurrence points in the Koto Mountain Range, and shows that N distresses occurred in August at the points specified by the east longitude E3 and the north latitude N3. This distress point is DD kilometers away from the search team waiting place R, and the altitude difference from the nearest mountain trail is FF meters. Thus, the search database 110 also stores the distance from the search unit waiting place R at each past distress point and the altitude difference from the mountain trail.

  Further, the search database 110 also stores a flight route for directing the flying device 3 to each distress occurrence point. As shown in FIG. 4, the search database 110 stores similar information for each month other than August.

  When there are a plurality of candidates for distress occurrence points to search for the user U, the route setting unit 122 refers to the search database 110 to fly the distress occurrence points with priority from the search unit standby station R. The flight route of the device 3 may be set. As a result, a place near the search party waiting place R is searched manually, and a place far from the search party waiting place R is searched toward the flying device 3 having a high moving speed. Therefore, the search support device 1 can improve the search efficiency of the user U.

  In general, it is considered that a place where many distresses have occurred in the past is likely to occur afterwards. Therefore, the route setting unit 122 may refer to the search database 110 and set a flight route by giving priority to a place where the number of past distress occurrences is high at a time corresponding to the mountain plan submitted by the user U. . For example, as shown in FIG. 3, when the schedule in the mountain planning is August, the route setting unit 122 refers to the search database 110 and gives priority to the distress occurrence points with a large number of past distress occurrences in August. The flight route of the flying device 3 is set. Thereby, the search assistance apparatus 1 can improve the search efficiency of the user U more.

  When the mountain area shown in the mountain plan of the user U is a mountain area with a good communication environment, the communication between the device T and the search support device 1 is interrupted, which means that there is a problem with the device T in the place where the communication is interrupted. Suggest that For example, when the user U walks down a rocky place or a snowfall, the device T breaks down, the user U is swept away while the device T is submerged, or the user U is caught in an avalanche and the device T falls under the snow. It is considered that a change has occurred in the environment surrounding the user U, such as being buried.

  Therefore, the route setting unit 122 sets the flight route of the flying device 3 with priority given to the distress occurrence point near the point where the communication with the device T was last interrupted among the distress occurrence points registered in the search database 110. May be. As a result, the flying device 3 searches for the user U by giving priority to an area having a high probability that the environment surrounding the user U has changed. As a result, the search support device 1 can further improve the search efficiency of the user U.

  Search corps tend to slow down when they move off a mountain trail that was created to move. In particular, the search for the location where the skidding is dangerous requires ensuring the safety of the search party itself, and also involves moving up and down, so the moving speed drops rapidly. On the other hand, since the flying device 3 can move in the air, the movement in the vertical direction is faster than the moving speed of the search party.

  Therefore, the route setting unit 122 refers to the search database 110 and gives priority to the distress occurrence points having a large difference in altitude from the mountain trail among the distress occurrence points registered in the search database 110. Set. Thereby, the search assistance apparatus 1 can improve the search efficiency of the user U more.

  Thus, the route setting unit 122 sets the flight route on which the flying device 3 flies in order to search for the user U. However, for example, when the distance between the distress occurrence point on the flight route and the search unit waiting place R is long, or when the altitude of the distress occurrence point is high, all the flying devices waiting at the search unit waiting place R are used. 3 is not necessarily guaranteed to be able to fly on the flight route set by the route setting unit 122.

Therefore, the storage unit 11 also stores a flight device database 111 that stores information on the flight performance of each of the plurality of flight devices 3.
FIG. 5 is a diagram schematically showing the data structure of the flying device database 111 according to the embodiment. Similar to the search database 110, the flying device database 111 is managed by the database management unit 123.

  The flying device database 111 stores information on the flight performance of the flying device 3 arranged in the search unit standby station R for each standby site ID for uniquely identifying each search unit standby station R. FIG. 5 exemplifies the flight performance information of each flying device 3 arranged in the search unit waiting place R whose waiting place ID is WID1234.

  As shown in FIG. 5, the search unit waiting place R whose waiting place ID is WID1234 is equipped with N flying devices 3 from the first flying device 3a to the Nth flying device 3n. For example, the cruising range of the first flying device 3a is L1 kilometers, and the cruising time is T1 hours. The highest altitude reached by the first flying device 3a is H1 meters. Similarly, the cruising range of the second flying device 3b is L2 kilometers, the cruising range is T2 hours, and the maximum altitude is H2 meters. The same applies to the Nth flying device 3n.

  The flying device selection unit 124 refers to the flying device database 111 and selects the flying device 3 capable of navigating the route set by the route setting unit 122. The flying device selection unit 124 transmits the route set by the flying device selection unit 124 to the selected flying device 3. Thereby, the search support device 1 can suppress a situation in which the flying device 3 cannot return to the flying device 3 without being able to fly on the route set by the route setting unit 122 or cannot fly on the way.

  Further, the route setting unit 122 may set the flight route in the range of the cruising performance of the flying device 3 that can fly by referring to the flying device database 111. Also in this case, the search support device 1 can suppress a situation in which the flying device 3 cannot return to the flying device 3 because it cannot fly the route set by the route setting unit 122 or cannot fly on the way.

  The flying device 3 includes an imaging device for imaging a subject around the flying device 3, and can transmit the captured image to the search support device 1. A user (for example, a member of a search team) of the search support device 1 can visually find the user U who is the search target by observing the image received from the flying device 3.

  Here, for example, when the flying device 3 is moving to move to the distress point, or when it is difficult to search the user U on the ground because it is flying over the forest zone, the flying device 3 searches for it. Sending an image to the support apparatus 1 is not efficient.

  Therefore, the route setting unit 122 may further set an imaging area indicating an area in which the imaging device included in the flying device 3 is operated in the flight route set to the flying device 3. More specifically, a search area in which the user U is to be searched is determined around the distress occurrence point, and an area in which the flying device 3 should fly in order to image the search area with the imaging device is an imaging area. For this reason, as shown in FIG. 4, the search database 110 also stores imaging instruction information for instructing the flying device 3 to perform imaging for each distress occurrence point, and the imaging instruction information includes a search area. ing. Thereby, since the search assistance apparatus 1 can suppress sending the captured image of the area | region which is not important for the search of the user U to the flight apparatus 3, the network N and a mobile telephone communication network also suppress congestion of a communication band. Can do.

  When the flying device 3 arrives at a distress occurrence point that is a candidate site for the search of the user U, which region the flying device 3 should image depends on the distress occurrence point. For example, when the distress point where the flying device 3 arrives is a so-called open space where the field of view is open, the flying device 3 should capture images in all directions. On the other hand, when the distress occurrence point where the flying device 3 arrived is a rock shade for the user U to hide from the snowstorm, the area on the leeward side of the rock should be focused on.

  Therefore, the search database 110 stores a direction instruction command indicating the position and direction to be photographed by the flying device 3 for each distress point. The route setting unit 122 refers to the search database, and further sets a direction instruction command for designating the shooting direction of the imaging device in the area indicated by the imaging route set to the flying device 3 to the flying device 3. Since the shooting position and shooting direction are set together with the flight route, the flying device 3 can start the imaging device and point the imaging unit in the designated shooting direction when arriving at the set shooting position. . Thereby, the search assistance apparatus 1 can improve the search efficiency of the user U more.

  When the flying device 3 images the vicinity of the distress occurrence point and transmits it to the search support device 1, the user of the search support device 1 can search for a search target person. Here, when the search target person exists near the distress occurrence point, for example, if some action such as waving a hand to the search target person is performed, the probability that the user of the search support device 1 finds the search target person increases. In the case where the flying device 3 is equipped with a thermosensor, the flying device 3 may recognize the presence or absence of a biological reaction using the thermosensor, or may recognize whether a person is reflected from the image information. . Upon recognizing these, the flying device 3 may cause the imaging device to take an enlarged image, or cause the imaging device to take an image while tracking the recognition target.

  Therefore, the route setting unit 122 further sets a reproduction area for reproducing the voice calling the user U who is the search target from the voice reproduction device (not shown) included in the flying device 3 among the imaging routes set in the flying device 3. May be. For this reason, as shown in FIG. 4, the search database 110 also stores reproduction instruction information for instructing the audio reproduction device of the flying device 3 to reproduce audio, and the reproduction area includes the reproduction instruction information. include. Thereby, the search assistance apparatus 1 can improve the search efficiency of the user U more.

  Moreover, if the user U who is a search subject answers to the sound reproduced by the sound reproduction device of the flying device 3, if the voice can be recorded, the user of the search support device 1 can identify the search subject. It can be useful information. Therefore, the route setting unit 122 may further set a recording instruction command for operating the recording device (not shown) included in the flying device 3 in the flying route set in the flying device 3. Therefore, as shown in FIG. 4, the search database 110 also stores recording instruction information for instructing the recording device of the flying device 3 to record voice. Thereby, the search assistance apparatus 1 can improve the search efficiency of the user U more.

<Processing flow of search support processing executed by search support device 1>
FIG. 6 is a flowchart for explaining the flow of search support processing executed by the search support device 1 according to the embodiment. The processing in this flowchart starts when the search support device 1 is activated, for example.

  The plan acquisition unit 120 acquires the mountain plan created by the user U (S2). The position information acquisition unit 121 acquires position information indicating the position of the device T possessed by the user U (S4). If communication from the device T has not continued for a predetermined period or longer (Yes in S6), the route setting unit 122 inquires the action plan management apparatus 2 for an arrival report from the user U and confirms it.

  If there is no arrival report from the user U (Yes in S8), the place where the predetermined time has elapsed from the arrival time indicated at the destination indicated by the mountain plan submitted by the user U or the way to the destination. (No in S10), the route setting unit 122 continues the arrival report inquiry from the user U.

  When there is no arrival report from the user U (Yes in S8) and a predetermined time has elapsed from the arrival time indicated in the mountain plan submitted by the user U or the passage place on the way to the destination (Yes in S10) The route setting unit 122 refers to the search database 110 to set a flight route that the flying device 3 should fly in order to search for the user U who is the search target (S12).

  The flying device selection unit 124 selects the flying device 3 that can fly the flight route selected by the route setting unit 122 by referring to the flying device database 111 (S14). The flying device selection unit 124 transmits the flight route set by the route setting unit 122 to the selected flying device 3 (S16).

  Whether communication from the device T is within a predetermined period (No in S6), if there is an arrival report from the user U to a destination or a transit place on the way to the destination (No in S8), or a flying device selection When the unit 124 transmits the flight route to the flying device 3, the processing in this flowchart ends. The search support device 1 realizes search support processing by repeating the above processing.

  FIG. 7 is a flowchart for explaining the flow of the flight route setting process executed by the route setting unit 122 according to the embodiment, and is a diagram for explaining step S12 in FIG. 6 in more detail.

  The route setting unit 122 refers to the search database 110 and acquires the distance between each distress occurrence point that is a candidate for the search of the user U and the search unit waiting place R (S120). The route setting unit 122 refers to the search database 110 and acquires the past number of distress occurrences at each distress occurrence point as a search candidate of the user U (S121).

  Further, the route setting unit 122 refers to the search database 110 and acquires the communication location where the device T possessed by the user U who is the search target last communicated with the search support device 1 (S122).

<Effects of search support device 1 according to the embodiment>
As described above, according to the search support device 1 according to the embodiment, it is possible to improve the search efficiency in a place where time is required for manual search. In particular, the search support device 1 according to the embodiment refers to the distress occurrence point in the mountain area indicated in the mountain travel plan submitted by the user U, so that the distress occurrence point related to the route indicated in the mountain travel plan. Set the flight route with priority. Thereby, the search assistance apparatus 1 can make the flight apparatus 3 face the point where the user U has a high probability of suffering.

  As mentioned above, although this invention was demonstrated using embodiment, the technical scope of this invention is not limited to the range as described in the said embodiment, A various deformation | transformation and change are possible within the range of the summary. is there. For example, the specific embodiments of device distribution / integration are not limited to the above-described embodiments, and all or a part of them may be configured to be functionally or physically distributed / integrated in arbitrary units. Can do. In addition, new embodiments generated by any combination of a plurality of embodiments are also included in the embodiments of the present invention. The effect of the new embodiment produced by the combination has the effect of the original embodiment.

<Modification>
In the above, the route setting unit 122 indicates that the user U has not yet received the time indicated by the mountain plan at the destination indicated in the mountain plan submitted by the user U or the passage place on the way to the destination for a predetermined time. The case where the flight route of the search flight apparatus 3 is set on the condition that the arrival and the communication with the device T of the user U has been interrupted for a predetermined period or more has been described. However, the trigger that the route setting unit 122 sets the flight route is not limited to the above.

  For example, the route setting unit compares the estimated distress time of the user U who is the search target and the search start time, and if the survivable time is exceeded, the range in which the user U can act within the survivable time ( Specifically, the range of a certain distance centered around the point at which communication between the search support device 1 and the device T was last interrupted is estimated, and the flight route is set with priority on the distress occurrence point within the range. May be.

  Here, the estimated time of distress is a predetermined time when the communication between the search support device 1 and the device T has been interrupted for a predetermined period or more, and the passing place and the time on the way to the destination indicated by the mountain plan are a predetermined time. When the time has not yet arrived, it is defined as the time at the last sighting point of the user U by another climber. If there is no sighting information due to reasons such as the absence of other climbers, the estimated time of distress is the most recent specified time after the climbing start time (for example, sudden change in weather around the mountain planning route, etc. Time of change).

  The survivable time is, for example, 72 hours when the survival rate suddenly decreases. Furthermore, the range in which the user U can act within the survivable time is defined as a region within a circle having the survivable time as a radius in the walking speed of the user U. The time at the last sighting point of the person to be searched by another climber is determined by the search team, who is the user of the search support device 1, from the contact information described in the mountain climbing plan of the other climber. And the latest time in the information obtained from the inquiry may be set in the flying object.

  In general, it is considered that the search subject has not moved for more than 72 hours. By limiting the range in which the user U can act within the survivable time, the search support device 1 can narrow down the distress occurrence points that the flying device 3 should search.
