  FIG. 5 is a flowchart showing the flow of search processing of the search support system 1.

(Step SP10)
The first terminal 12A transmits a search request including search request information input by the search requester to the search support server 10 in response to the operation of the search requester. The search request information includes the name and gender of the search target person, the terminal ID of the second terminal 14, position information of the second terminal 14 when it is missing (position information of the search target person), and the like. And a process transfers to the process of step SP12.

(Step SP12)
The receiving unit 72 of the search support server 10 receives (receives) a search request from the first terminal 12A. Then, the reception unit 72 stores (registers) search request information included in the received search request in the search request reception table 70C. And a process transfers to the process of step SP14.

(Step SP14)
The support unit 74 of the search support server 10 refers to the personal information table 70A, acquires personal information that matches the name included in the search request information, and sends the search request to which the acquired personal information is added within a predetermined search area. Push notification is sent to each first terminal 12B. And a process transfers to the process of step SP16. Although not shown, the support unit 74 transmits a position request to each first terminal 12C. Each first terminal 12C receives the position request, and in response to this, transmits the position information of the first terminal 12C to the search support server 10. And a process transfers to the process of step SP16.

(Step SP16)
Each first terminal 12B receives a push notification from the search support server 10. In response to this reception, the display control unit 62 of each first terminal 12B controls display of search request information included in the push notification on the screen of the first terminal 12B. When the searcher touches the location where the search request information is displayed, the communication control unit 60 of each first terminal 12B controls the wireless LAN communication unit 40 to make the touch (search approval) and each The position information of the one terminal 12B is transmitted to the search support server 10. And a process transfers to the process of step SP18. Note that the position information of each first terminal 12B and each second terminal 14 is repeatedly transmitted to the search support server 10 until the search is completed.

(Step SP18)
The receiving unit 72 of the search support server 10 receives the touch effect and the position information from each first terminal 12B. The receiving unit 72 also receives position information from each second terminal 14. In response to this reception, the support unit 74 of the search support server 10 provides each first terminal 12B with a search start instruction including the received plurality of position information and the position information of the second terminal 14 when missing. Send. And a process transfers to the process of step SP20 and 22.

(Step SP20)
The search support server 10 executes processing related to passing communication (passing communication processing). Details of the passing communication process will be described later.

(Step SP22)
The first terminal 12B receives a search start instruction from the search support server 10. In response to this, the display control unit 62 of the search application 42A acquires a map around the position indicated by the position information of the second terminal 14 when it is missing. This map may be acquired from the search support server 10 or may be acquired from another server or the like. When acquiring from the search support server 10, you may receive with a search start instruction. Further, if the capacity of the storage unit 42 of the first terminal 12B is large, a map may be stored in the storage unit 42 and the map may be acquired from the storage unit 42. Then, the display control unit 62 controls the display 32A and displays the acquired map. The display control unit 62 controls the display 32A, and the position indicated by the position information of the first terminal 12B and the position information of the other first terminal 12B and each first terminal 12C are displayed on the displayed map. The position to be displayed is displayed. Further, the display control unit 62 controls the display 32A, and on the displayed map, the first communicable range based on the position indicated by the position information of the first terminal 12B, the other first terminals 12B, and the first terminals. The 2nd communication possible range based on the position which each of 12C position information shows is displayed.

  FIG. 7 is a diagram illustrating an example of the map 100 displayed on the display 32 </ b> A of the first terminal 12 </ b> B by the display control unit 62.

In the map 100 shown in FIG. 7, the position 104A indicated by the position information of the first terminal 12B, the position 104B indicated by the position information of the other first terminal 12B and each of the first terminals 12C, and the position 104A are the center. A circular first communicable range 106A and a circular second communicable range 106B centered on the position 104B are displayed. The first communicable range 106A and the second communicable range 106B are generally colored (for example, translucent red). Note that only the outlines of the first communicable range 106A and the second communicable range 106B may be colored, and the inside may be transparent.
The map 100 displays a set communication range 108 centered on the first terminal 12B. The set communication range 108 is a communication range of the first terminal 12B according to the set communication power value set in the first terminal 12B. Therefore, the size of the set communication range 108 can be changed by the searcher operating the first terminal 12B to change the set communication power value. When the first communicable range 106A is referred to as an outer circle, the set communication range 108 can be referred to as an inner circle.

  Returning to FIG. 5, the process proceeds to the process of step SP24.

(Step SP24)
The changing unit 64 of the first terminal 12B determines whether or not the success notification indicating that the predetermined first terminal 12 has succeeded in passing communication with the second terminal 14 has been received from the search support server 10. If the determination is affirmative, the process proceeds to the process of step SP26. If the determination is negative, the process returns to the process of step SP24. Details of the success notification will be described later. In addition, the display of the map 100, the positions 104A, 104B, and the like is appropriately updated by the display control unit 62 as time passes.

(Step SP26)
The changing unit 64 changes the display mode of the communicable range corresponding to the first terminal 12 that has succeeded in passing communication among the first communicable range 106A and the second communicable range 106B. For example, when the first terminal 12B succeeds in passing communication, the display mode of the first communicable range 106A corresponding to the first terminal 12B is changed, and when the first terminal 12C succeeds in passing communication, the second terminal The display mode of the second communicable range 106B corresponding to the terminal 14 is changed. In the first embodiment, the changing unit 64 changes the entire display color of the corresponding communicable range from red to blue.
As a result, if the color of the displayed first communicable range 106A or the second communicable range 106B is red, it can be understood that the search target person does not exist within the range and is displayed. If the color of the first communicable range 106A or the second communicable range 106B is blue, it is possible to grasp that the search target person exists within the range.

  In the first embodiment, since not only the first communicable range 106A but also the set communication range 108 is displayed, the changing unit 64 may change the display color of the set communication range 108. Since the set communication range 108 is a part of the first communicable range 106A, even in this case, the display color of the first communicable range 106A is changed.

  Here, when the first communicable range 106A and the second communicable range 106B overlap, the changing unit 64 can communicate with the one corresponding to the first terminals 12B and 12C that have successfully communicated with the second terminal 14. The display mode of at least one of the first communicable range 106A or the second communicable range 106B is changed so that the outline of the region excluding a portion overlapping with the other communicable range is emphasized (displayed). To do.

  FIG. 8 is an enlarged view of the first communicable range 106A and the second communicable range 106B displayed when the first communicable range 106A and the second communicable range 106B overlap. In FIG. 8, it is assumed that the first terminal 12B has successfully communicated with the second terminal 14.

  As shown in FIG. 8, in the communication range 106 of the first terminal 12B that has succeeded in communication with the second terminal 14, an area excluding a portion that overlaps with the other communication range (second communication range 106B). The contour 110 is displayed (emphasized). If the second communicable range 106B is red and the corresponding other first terminals 12B and 12C have not succeeded in communication, the search target person exists at any position in the area within the contour 110. It will be.

  Returning to FIG. 5, the process proceeds to the process of step SP28.

(Step SP28)
The changing unit 64 determines whether or not a button (discovery button) (not shown) that reports that the search target person has been found has been pressed. If the determination is affirmative, the process proceeds to step SP30. If the determination is negative, the process proceeds to step SP24.

(Step SP30)
The first terminal 12B acquires the location information of the first terminal 12B, generates a discovery notification that includes the location information and indicates that the search target person has been discovered, and transmits the discovery notification to the search support server 10 . And a process transfers to the process of step SP32.

(Step SP32)
The receiving unit 72 of the search support server 10 receives a discovery notification from the first terminal 12B. In response to this, the support unit 74 of the search support server 10 stores the discovery notification in the search request reception table 70C. Then, the support unit 74 transfers the discovery notification to the first terminal 12A and the other first terminal 12B. And a process transfers to the process of step SP34.

(Step SP34)
The first terminal 12 </ b> A receives the discovery notification from the search support server 10. In response to this, the first terminal 12A displays the received discovery notification.

  FIG. 6 is a flowchart showing the flow of the passing communication process in step SP20 shown in FIG.

(Step SP40)
The search support server 10 transmits a passing communication start instruction to the first terminals 12B and 12C via the communication network NT. This start instruction includes, for example, the terminal ID of the second terminal 14 carried by the person to be searched for the search request. And a process transfers to the process of step SP42.

(Step SP42)
The first terminals 12B and 12C receive a start instruction from the search support server 10 via the communication network NT. And a process transfers to the process of step SP44.

(Step SP44)
The communication control unit 60 of the first terminals 12B and 12C starts passing communication. And a process transfers to the process of step SP46.

(Step SP46)
When the first terminals 12B and 12C and the second terminal 14 pass each other (when they are close to each other), they communicate with each other, that is, automatically detect each other and automatically transmit and receive each other's terminal ID. And a process transfers to the process of step SP48.

(Step SP48)
The communication control unit 60 of the first terminals 12B and 12C determines whether or not the terminal ID acquired by the passing communication matches the terminal ID included in the start instruction. If the determination is affirmative, the process proceeds to step SP50. If the determination is negative, the process proceeds to step SP56. The search support server 10 may execute the process of step SP48.

(Step SP50)
The first terminals 12B and 12C acquire the current position information of the first terminals 12B and 12C using GPS (Global Positioning System) or the like. Then, the communication control unit 60 of the first terminals 12B and 12C sends the search information including the fact that the terminal IDs match, or the passing communication with the search target person, and the acquired location information via the communication network NT. To the search support server 10 (notification). And a process transfers to the process of step SP52.

(Step SP52)
Search support server 10 receives search information from first terminals 12B and 12C via communication network NT. Then, the search information is stored in the storage unit 70 of the search support server 10, and a success notification is notified (transferred) to each of the first terminals 12B and 12C. And a process transfers to the process of step SP54.

(Step SP54)
The search support server 10 instructs the stop of the passing communication when the search request is stopped from the family of the search target or when the search target is received after the search information is notified. Is transmitted to the first terminals 12B and 12C via the communication network NT. And a process transfers to the process of step SP56.

(Step SP56)
The first terminals 12B and 12C receive a stop instruction from the search support server 10 via the communication network NT. In response to this, the first terminals 12B and 12C stop passing communication.

As described above, in the first embodiment, the searcher confirms the display modes of the displayed first communicable range 106 </ b> A and the second communicable range 106 </ b> B, and these display modes are the modes before the change by the changing unit 64. If it exists, it can be estimated that the search target person does not exist within the range and the search target person exists outside the range. In this way, the searcher can narrow down the position (estimated position) where the search target person is estimated to exist by confirming the display mode of the first communicable range 106A and the second communicable range 106B. In other words, the search application 42A according to the first embodiment can assist in narrowing down the estimated position of the search target person. Therefore, according to the first embodiment, the searcher can efficiently search for the search target person.
In the first embodiment, the searcher confirms the display mode of the displayed first communicable range 106A and the second communicable range 106B, and if any of these display modes is a changed mode. For example, it can be estimated that the search target person exists within the communicable range corresponding to the display mode after the change, and the position (estimated position) estimated to be the search target person can be narrowed down.

  In the first embodiment, when the first communicable range 106A and the second communicable range 106B overlap, the other communicable range of the communicable ranges corresponding to the successful first terminals 12B and 12C is possible. Since the outline of the area excluding the portion overlapping the range is displayed, it can be estimated that the search target person exists in the area within the outline. In this manner, the searcher can further narrow down the position (estimated position) where the search target person is estimated to exist by confirming the region within the outline.

  In the first embodiment, the set communication range corresponding to the set communication power set in the first terminal 12B is displayed, and when the first terminal 12B succeeds in communication with the second terminal 14, the set communication is performed. Since the display mode of the range is changed, the searcher can change the communication range and the display thereof by changing the set communication power. Using this change, the searcher adjusts the set communication power to narrow the set communication range, and when the display color of the set communication range returns from blue to red, the search target person is within the set communication range. Does not exist, the search target person exists in the area excluding the set communication range after the change from the set communication range before the change, and further narrow down the position (estimated position) where the search target person is presumed to exist be able to.

Second Embodiment
Next, a search support system according to the second embodiment will be described. In the search support system according to the second embodiment, the structure of the search support system 1 of the first embodiment is analyzed on the map by analyzing the direction of movement of the search target person when the search target person is missing. A configuration to display has been added.

  FIG. 9 is a diagram illustrating an example of a search support system according to the second embodiment. As shown in FIG. 9, the search support system 120 according to the second embodiment is provided in a specific area 122 such as an internal area in a building such as a hospital or a house, or an external area such as an amusement park or a park. ing. The search support system 120 includes a plurality of monitoring devices 124 and a device management device 126. In the second embodiment, five monitoring devices 124 are provided, which are referred to as monitoring device 124A, monitoring device 124B, monitoring device 124C, monitoring device 124D, and monitoring device 124E, respectively.

  Each of the plurality of monitoring devices 124 communicates with the second terminals 14 in and around the specific area 122 and monitors (acquires) the signal strength returned from the second terminal 14. In addition, the monitoring device 124 transmits the monitored signal strength to the device management apparatus 126.

  The device management device 126 manages a plurality of monitoring devices 124, receives the signal strength from each monitoring device 124, and based on each signal strength, whether or not the search target person P leaves the specific area 122 and is missing If it is determined that the search target person P is missing, the movement direction of the search target person is analyzed based on the history of each signal intensity. Then, the device management apparatus 126 transmits the analysis result to the search support server 10. The search support server 10 transfers the analysis result to the first terminal 12, and the first terminal 12 displays the analysis result (movement direction) on the map.

  Further, the device management apparatus 126 may transmit a search request for the search target person P to the search support server 10. The device management apparatus 126 may also have the function of the monitoring device 124.

  For example, the device management device 126 determines whether or not at least one of the signal intensities has become zero, and if it has become zero, the search target person P has left the specific area 122 and has gone missing. judge. Further, as shown in FIG. 9, the device management device 126 has the signal strength (from the second terminal 14) of the device management device 126 becomes zero due to the movement of the search target person based on the history of each signal strength. In the monitoring device 124A and the monitoring device 124E, when the signal strength from the second terminal 14 changes from weak to strong and eventually the communication strength becomes zero, the search target person P leaves the specific area 122 and goes away. You may determine that it became unknown.

  As shown in FIG. 9, in the device management apparatus 126, the signal strength of the monitoring device 124A and the monitoring device 124E (from the second terminal 14) is reduced, and the signal strength of the monitoring device 124A is zero. If the signal intensity of the monitoring device 124E is maintained, the movement of the search target person P when the search target person P is missing when the movement is in the direction of the monitoring apparatus 124E from the monitoring device 124A. Analyze direction. Similarly, in the device management apparatus 126, the signal strength of the monitoring device 124A and the monitoring device 124E (from the second terminal 14) decreases, the signal strength of the monitoring device 124E becomes zero, and the signal strength of the monitoring device 124A. Is maintained, the direction of movement of the search target person P when the search target person P is missing is analyzed when the movement of the search target person P is missing.

  As described above, according to the second embodiment, since the movement direction of the search target person P when the search target person P is missing is displayed on the map, for example, the search range is the range on the movement direction side on the map. The search target person P can be searched efficiently.
