Description

  The present invention relates to a mobile object display system and a mountain rescue system, and more particularly to means for expanding a service area for the mobile terminal.

  In this specification / drawing, the infrastructure mode is a mode in which mobile terminals communicate with each other via an access point repeater of the infrastructure network, and the ad hoc mode is a repeater in which the mobile terminals are access points. In this mode, direct wireless communication is performed without going through the network.

  A mobile terminal capable of moving by switching a communication mode between an infrastructure (infrastructure) network and an ad hoc area and a control method thereof have been proposed (see, for example, Patent Document 1).

  In addition, the sender's position information is transmitted from the transmission means set to the person through a communication network such as the Internet to the data processing means storing a database of various information, and the person's position is identified and rescued. There has been proposed a deaf support system that transmits a relieving position and a remedial command to a service provider and provides a defensive service. In this case, the start signal from the deeder position information starter set for the deer is transmitted via GPS or the like. (For example, refer to Patent Document 2).

Embodiment 1
In the first embodiment, an eavesdropper is exemplified as a mobile object to be searched for, but the search target is not limited to this. For example, it may be a child or student going out for school, play, cram school, etc. It can also be applied to animals that are endangered.

  FIG. 1 is a block diagram showing a system configuration of an embodiment of a mobile display system according to the present invention.

  The portable terminal 103 is a portable terminal carried by a search target person, and is an apparatus including an antenna 201 that transmits and receives GPS radio waves and a display 206 that displays a face photograph of the person carrying the portable terminal.

  The information processing apparatus 101 communicates with the searcher's mobile terminal 103 via the repeater 102, acquires the location information of the searcher's mobile terminal 103 obtained using GPS, The data is distributed to the mobile terminals 104 and the display devices 105 of a plurality of searchers.

  The information processing apparatus 101, the repeater 102, and the display apparatus 105 are connected by a communication line 106 such as an existing intranet.

  The communication mode determination device 107 determines whether the communication mode of the searcher's mobile terminal 103, which will be described later, is an infrastructure mode or an ad hoc mode, and displays the position and movement locus of the searcher on the screen of the display device 105. Switching is determined (see FIG. 12).

  FIG. 2 is a block diagram illustrating an example of the internal configuration of the mobile terminal 103.

  The GPS antenna 201 transmits and receives radio communication radio waves. The transmission / reception means 202 receives the radio communication radio wave from the GPS antenna 201 and transmits the content commanded from the communication control means 203 to the repeater 102.

The communication control unit 203 controls transmission / reception of information with the information processing apparatus 101.
The memory 204 stores a moving body display system control program using GPS radio waves, a search person's movement trajectory, search person's image information, and the like.

  The image conversion unit 205 converts the image information of the searched person received via the communication control unit 203 into a state of displaying on the display unit 206. The display unit 206 displays a face photograph of the search subject converted by the image conversion unit 205.

  The switching means 207 is a switch for switching the communication mode, and sets one of the three modes of infrastructure mode, ad hoc mode, and automatic mode. The automatic mode is a mode for determining whether the mode is the infrastructure mode or the ad hoc mode based on whether radio waves are periodically emitted and communication with the information processing apparatus 101 can be performed via the repeater 102.

  In this embodiment, the position of the search target is specified using a GPS antenna. Instead of this method, it is possible to install a radio communication antenna and specify the position by the phase difference of radio communication, or install a regional promotion radio antenna and specify the position by electric field strength. In addition to position information, information such as sound, images, and moving images may be communicated.

  FIG. 3 is a block diagram illustrating an example of an internal configuration of the information processing apparatus (center computer) 101.

  The wireless device 301 transmits and receives radio communication radio waves. The processing device 302 uses the phase difference of the radio wave of the wireless communication for the information on the search person stored in the storage device 303 and the position information of the search person obtained via the wireless device 301. The mobile body display system control program 304 for searching is stored. These information and programs are processed or executed by the processing device 302.

  The display device 305 is connected to the processing device 302 and displays the position information of the searched person on the map. The input device 306 is a keyboard, a mouse, or the like for designating a search target person to be searched or starting the mobile object display system control program 304.

  FIG. 4 is a flowchart showing the search procedure for the search target person in the information processing apparatus (center computer) 101.

  When the searcher falls into a dangerous state and reports that the searcher's mobile terminal 103 is in a dangerous state toward the information processing apparatus 101, or the searcher's family In response to a request to search for the information, the person in charge of the system inputs information such as the name of the search target person from the input device 306 (step 401).

  The processing device 302 of the information processing device 101 transmits the input information to the storage device 303 (step 402).

  The processing device 302 searches the storage device 303 for specific information such as a searchee's registration number, name, face photo, age, address, etc. by the moving body display system control program 304 (step 403).

  The processing device 302 causes the display device 305 to display the unique information, and transmits the obtained registration number of the search target person to the searcher's mobile terminal 104 (step 404).

  FIG. 5 is a diagram illustrating an example of display on the display device 305 of the information processing apparatus (center computer) 101.

  Three-point surveying is executed based on the phase difference of radio communication radio waves from the three repeaters, and the measured position information of the searched person is displayed on the map data 501 using the mobile object display system control program 304 or the like. .

  The position 502 of the searched person is position information of the searched person that is periodically acquired from the portable terminal 103 and accumulated in the information processing apparatus 101. When the position 502 of the search target person is displayed, the acquired time data 503 is also displayed.

  The time, time, and locus of the searcher's movement can be known from the line 504 drawn on the map in time series with the positions 502 of the searchees.

  The other screen displays a face photograph of the search subject and unique information 505 such as age.

  In the three-point surveying, the positions of the three repeaters are clear, and if the portable terminal cannot receive the radio waves from the three repeaters, the position of the portable terminal cannot be specified accurately.

  However, even when radio waves can be received only from two or one repeater, the approximate range of the position can be known by displaying a circle of received radio wave intensity on the map.

  This method is an effective position determination and display method when surveying by wireless communication is possible even if the position cannot be specified by GPS.

  FIG. 6 is a flowchart showing a processing procedure for displaying a face photograph of the searched person in the searcher's portable terminal 104.

  The transmission / reception means 202 of the searcher's mobile terminal 104 receives the registration number of the searchee transmitted from the information processing apparatus 101 in step 404 via the repeater 102 and the wireless communication antenna 201 (step 601).

  Using the registration number as a key, the communication control means 203 extracts the corresponding person's face photo data from the memory 204 in the portable terminal, and displays the face photo on the display 206 (step 602).

  FIG. 7 is a flowchart illustrating a position search processing procedure when the user exits from a wireless communication service area.

  That is, when the searcher goes out of the area that covers the wireless communication in the infrastructure mode that communicates via the repeater 102, the communication mode of the portable terminal when searching for the searchee's position and the search target are searched. It is a flowchart regarding the screen display to a search target terminal of a searcher's movement locus | trajectory.

  When radio waves periodically transmitted from the information processing apparatus 101 do not reach the searcher's mobile terminal 103, the searcher's mobile terminal 103 detects that the mobile terminal 103 has gone out of the infrastructure mode (step 701).

  The searcher's mobile terminal 103 transmits a radio wave to search for a searchable mobile terminal 104 that can communicate (step 702), and communicates directly with the searcher's mobile terminal 104 that has received the radio wave. Communication is performed (step 703).

  The position of the searcher's mobile terminal 103 is displayed on the screen of the searcher's mobile terminal 104 following the track in the infrastructure mode (step 704).

  Even after the mobile terminals 103 and 104 enter the ad hoc mode, the mobile terminal 103 and 104 are temporarily set in the infrastructure mode in order to continue to send information to the information processing apparatus 101 unless there is a new communication request from another mobile terminal. Returning, it is determined whether infrastructure mode communication is possible (step 705).

  Therefore, when the searchee's mobile terminal 103 returns to the infrastructure mode area, communication is started in the infrastructure mode (step 706).

  When the infrastructure mode communication is impossible, the mobile phone returns to the ad hoc mode and transmits a radio wave for searching for another mobile terminal capable of communication (step 702).

  FIG. 8 is a flowchart showing a position search processing procedure after leaving the wireless communication service area.

  The searchee's mobile terminal 103 measures its own position by GPS or the like, and stores the measured position information in its own memory 204 (steps 801 and 802).

  The searchee's portable terminal 103 determines whether the communication is in the infrastructure mode or the ad hoc mode (step 803).

  If the searchee's mobile terminal 103 is communicating in the infrastructure mode, the stored location information log is transmitted to the information processing apparatus 101 and deleted from the memory (step 804).

  The searcher's mobile terminal 103 holds a log in the memory when communicating in the ad hoc mode (step 805).

  The retained log is transmitted to the information processing apparatus 101 when the searchee's mobile terminal 103 returns to the infrastructure mode area and resumes communication in the infrastructure mode. If the memory capacity is exceeded, the oldest one is deleted.

  The searcher's mobile terminal 104 repeats the processes shown in FIGS. 7 and 8 to track the position of the searcher's mobile terminal 103.

  FIG. 9 is a diagram illustrating the exchange of information between devices in the ad hoc mode.

  The searcher's mobile terminal 103 and the searcher's mobile terminal 104 communicate in an ad hoc mode (step 901).

  As shown in the lower part of FIG. 8, when the searcher's mobile terminal 104 once returns to the infrastructure mode area, the log is transmitted to the information processing apparatus 101 (step 902).

  The information processing apparatus 101 displays the trajectory of the searcher on the display device 305 and transmits it to the searcher's mobile terminal 104 to update the searcher's trajectory in the searcher's mobile terminal 104 (steps 904 and 905). ).

  During the procedure, the searcher's mobile terminal 103 and the searcher's mobile terminal 104 can continue to communicate in the ad hoc mode (step 903).

  FIG. 10 is a diagram illustrating exchange of information between devices in the infrastructure mode.

  If the searcher's mobile terminal 103 is located in the infrastructure mode area, the information processing apparatus 101 switches the communication mode to the infrastructure mode and receives the searcher's location information (step 1001).

  The information processing apparatus 101 transmits the searcher's unique information obtained by the moving body display system control processing program to the display apparatus 305 and the searcher's mobile terminal 104 (steps 1002 and 1003).

  FIG. 11 is a flowchart showing a processing procedure for displaying the trajectory of the searched person on the searcher's mobile terminal 104.

  The searcher's mobile terminal 104 periodically acquires the position information of the search person, for example, from the phase difference of the radio communication radio wave (step 1101), and transmits the position information to the information processing apparatus 101 (step 1102). .

  On the other hand, the searcher's mobile terminal 104 receives the searcher's unique information from the information processing apparatus 101 and displays it on the screen (step 1103).

  Further, the position information of the search subject is periodically received, and the movement trajectory is displayed on the screen (step 1104).

  FIG. 12 is a flowchart showing a processing procedure for displaying the movement trajectory of the searched person in the information processing apparatus (center computer) 101.

  First, map data is displayed on the display device 305 (step 1201), and the position information of the searcher periodically transmitted from the searchee's mobile terminal 103 is received and stored in the storage device 303 (step 1202). ).

  The position data stored in the storage device 303 is superimposed on the map data, and the position and time data are displayed on the display device 305 (step 1203).

  The displayed plurality of pieces of position information are connected on the map as a trajectory and displayed on the display device 305 (step 1204).

  Knowing the trajectory of the searcher's movement, even if the searcher goes out of the coverage area of this mobile object display system, confirm the point from which the searchee went out of the coverage area and promptly search the searcher. Can be found.

  As shown in this embodiment, if the time is displayed in correspondence with the trajectory connected with the position information, the supervisor who monitors the trajectory can be attached to the searchee (deaf person) in the trajectory from the time interval and trajectory. Recognize important location information such as strong places.

  FIG. 13 is a diagram illustrating an example of a distinction display between infrastructure mode communication and ad hoc mode communication on the display device 305 of the information processing apparatus (center computer).

  By displaying on the screen which mode is used for communication, not only the position in the conventional infrastructure mode area but also the position in the ad hoc mode area can be grasped, and the area where the searcher is likely to go Can be identified.

  In addition, it can be used for planning an antenna maintenance plan for expanding the infrastructure mode area in the future, or can be displayed as a past history when searching for a search target with a defect, and the search can be completed at an early stage.

<< Embodiment 2 >>
If you adopt a method that digitizes the mountain climbing plan, stores it in a mobile terminal in advance, and transfers it to an information processing device installed at the management center at the mountain entrance prior to the start of mountain climbing, it becomes a mountain rescue system that tracks and displays climbers, Useful for disaster relief in case of emergency.

  In order to avoid congestion at the start of mountain climbing at the management center, it is desirable to submit a mountain climbing plan in advance through the Internet.

  For example, when a climber who has previously submitted a computerized climbing plan to the management center stops at the management center at the entrance and presses the departure time stamp himself . Further, the tracking of a climber is terminated when, for example, the user climbs down to a management center at any one of the mountain entrances and presses the arrival time stamp himself.

  The image conversion unit 205 converts the mountain climber image information received via the communication control unit 203 into a state of being displayed on the display unit 206. The display unit 206 displays a mountain climber's face photograph converted by the image conversion unit 205.

  The switching means 207 is a switch for switching the communication mode, and sets one of the three modes of infrastructure mode, ad hoc mode, and automatic mode. The automatic mode is a mode for determining whether the mode is the infrastructure mode or the ad hoc mode based on whether radio waves are periodically emitted and communication with the information processing apparatus 101 can be performed via the repeater 102.

  In this embodiment, the position of the climber is specified using a GPS antenna. Instead of this method, it is possible to install a radio communication antenna and specify the position by the phase difference of radio communication, or install a regional promotion radio antenna and specify the position by electric field strength. In addition to position information, information such as sound, images, and moving images may be communicated.

  The wireless device 301 transmits and receives radio communication radio waves.

  The processing device 302 searches for the position of the climber using the phase difference of the radio communication radio wave from the climber information stored in the storage device 303 and the climber position information obtained via the wireless device 301. A mobile display system control program 304 is stored. These information and programs are processed or executed by the processing device 302.

  The display device 305 is connected to the processing device 302 and displays the position information of the climber on the map. The input device 306 is a keyboard, a mouse, or the like for designating a search target climber or starting the mobile object display system control program 304.

  However, even when radio waves can be received only from two or one repeater, the approximate range of the position can be known by displaying a circle of received radio wave intensity on the map.

  The above FIG. 6 is diverted as a flowchart showing a processing procedure for displaying a face photograph of a climber in the portable terminal 104 of the rescue team.

  The transmission / reception means 202 of the portable terminal 104 of the rescue team receives the climber's registration number transmitted from the information processing apparatus 101 in step 404 via the repeater 102 and the wireless communication antenna 201 (step 601).

  Using the registration number as a key, the communication control means 203 extracts the corresponding person's face photo data from the memory 204 in the portable terminal, and displays the face photo on the display 206 (step 602).

  The above FIG. 7 is diverted as a flow chart showing a position search processing procedure when leaving the wireless communication service area.

  That is, when a climber goes out of an area that covers infrastructure mode wireless communication that communicates via the repeater 102, for example, when he / she gets lost in a valley, when searching for a climber's position It is a flowchart regarding the screen display on the climber terminal of the communication mode switching of the portable terminal and the climber's movement trajectory.

  When the radio wave periodically transmitted from the information processing apparatus 101 does not reach the mountaineer's mobile terminal 103 in the valley, the mountaineer's mobile terminal 103 detects that he has gone out of the infrastructure mode (step 701). .

  The climber's mobile terminal 103 transmits a radio wave for searching for the rescue rescue mobile terminal 104 (step 702), and directly communicates with the rescue team mobile terminal 104 that has received the radio wave. (Step 703).

  The position of the mobile terminal 103 of the climber is displayed on the screen of the mobile terminal 104 of the rescue team following the locus in the infrastructure mode (step 704).

  Even after the mobile terminals 103 and 104 enter the ad hoc mode, the mobile terminal 103 and 104 are temporarily set in the infrastructure mode in order to continue to send information to the information processing apparatus 101 unless there is a new communication request from another mobile terminal. Returning, it is determined whether infrastructure mode communication is possible (step 705).

  Therefore, when the climber's mobile terminal 103 returns to the infrastructure mode area, communication is started in the infrastructure mode (step 706).

  When the infrastructure mode communication is impossible, the mobile phone returns to the ad hoc mode and transmits a radio wave for searching for another mobile terminal capable of communication (step 702).

  The above FIG. 8 is diverted as a flowchart showing a position search processing procedure after leaving the wireless communication service area.

  The climber's mobile terminal 103 measures its own position by GPS or the like, and stores the measured position information in its own memory 204 (steps 801 and 802).

  The climber's mobile terminal 103 determines whether the communication is in the infrastructure mode or the ad hoc mode (step 803).

  When communicating in the infrastructure mode, the climber's mobile terminal 103 transmits a log of the stored location information to the information processing apparatus 101 and deletes it from the memory (step 804).

  The climber's mobile terminal 103 holds the log in the memory when communicating in the ad hoc mode (step 805).

  The retained log is transmitted to the information processing apparatus 101 when the climber's mobile terminal 103 returns to the infrastructure mode area and resumes communication in the infrastructure mode. If the memory capacity is exceeded, the oldest one is deleted.

  The rescue terminal mobile terminal 104 repeats the processes shown in FIGS. 7 and 8 to track the position of the mobile terminal 103 of the climber.

  FIG. 9 is used as a diagram showing information exchange between devices in the ad hoc mode.

  The climber's mobile terminal 103 and the rescue team's mobile terminal 104 communicate in an ad hoc mode (step 901).

  As shown in the lower part of FIG. 8, when the portable terminal 104 of the rescue team once returns to the infrastructure mode area, the log is transmitted to the information processing apparatus 101 (step 902).

  For example, if a climber who cannot move due to distress is in the bottom of the valley and cannot communicate in infrastructure mode, the rescue team that communicated in ad hoc mode will move to a place with high visibility with a portable terminal 104 as high as possible. The log stored in the climber's portable terminal 103 is transferred to the information processing apparatus 101.

  The information processing apparatus 101 displays the trail of the climber on the display device 305 and transmits it to the portable terminal 104 of the rescue team, and updates the trail of the climber on the portable terminal 104 of the rescue team (steps 904 and 905).

  Even during the procedure, the mobile terminal 103 of the climber and the mobile terminal 104 of the rescue team can continue communication in the ad hoc mode (step 903).

  The above FIG. 10 is diverted as a diagram showing the exchange of information between each device in the infrastructure mode.

  When the climber's mobile terminal 103 is located in the infrastructure mode area, the information processing apparatus 101 switches the communication mode to the infrastructure mode and receives the climber's position information (step 1001).

  The information processing apparatus 101 transmits the climber's unique information obtained by the mobile body display system control processing program to the display apparatus 305 and the portable terminal 104 of the rescue team (steps 1002 and 1003).

  The above FIG. 11 is diverted as a flowchart showing the processing procedure of the trail display of the climber in the portable terminal 104 of the rescue team.

  The mobile terminal 104 of the rescue team periodically acquires the position information of the climber from, for example, the phase difference of radio communication radio waves (step 1101), and transmits the position information to the information processing apparatus 101 (step 1102).

  On the other hand, the portable terminal 104 of the rescue team receives the climber's unique information from the information processing apparatus 101 and displays it on the screen (step 1103).

  Further, the position information of the climber is periodically received and the movement trajectory is displayed on the screen (step 1104).

  The above FIG. 12 is diverted as a flowchart showing a processing procedure for displaying a climber's movement trajectory in the information processing apparatus (center computer) 101.

  First, map data is displayed on the display device 305 (step 1201), and the climber's location information periodically transmitted from the climber's mobile terminal 103 is received and stored in the storage device 303 (step 1202).

  The position data stored in the storage device 303 is superimposed on the map data, and the position and time data are displayed on the display device 305 (step 1203).

  The displayed plurality of pieces of position information are connected on the map as a trajectory and displayed on the display device 305 (step 1204).

  Once the climber's movement trajectory is known, even if the climber goes out of the cover area of the mobile object display system, it is possible to confirm from which point the climber has gone out of the cover area and quickly find the climber.

  If the time is displayed in correspondence with the trajectory connected with the position information as in the present embodiment, there is a possibility that the climber is evacuating from the time interval and the trajectory of the supervisor who monitors the trajectory. Recognize or estimate important location information such as high places.

  The above FIG. 13 is used as a diagram showing an example of the distinction display between the infrastructure mode communication and the ad hoc mode communication on the display device 305 of the information processing apparatus (center computer).

  By displaying on the screen which mode is used for communication, not only the location in the conventional infrastructure mode area but also the location in the ad hoc mode area can be grasped, and the region where the climber is likely to go is identified. it can.

  In addition, it can be used for planning an antenna maintenance plan for expanding the infrastructure mode area in the future, and when searching for a climber when a distress accident occurs next time, it is displayed as a past distress case and the search procedure is displayed. You can make a quick decision, and decide where to place rescue workers who will relay between infrastructure mode communication and ad hoc mode communication.

  Although not shown here, the information processing apparatus is a record that accumulates a movement trajectory that combines the movement trajectory of the distress in the infrastructure mode and the movement trajectory of the distress in the ad hoc mode as data of the distress accident record. It may be provided as a reference material for preventing accidents of climbers via the Internet, for example.

  Further, the display device 105 in FIG. 1 displays management information for the entire management center at the entrance, and displays a map of the entire mountain area to be managed, like a large screen display device for an air traffic control system. You can check whether all climbing parties have arrived at the mountain hut or camp in the evening, and you can narrow down the alert target from the parties that have arrived late.
