  Hereinafter, the present embodiment will be described with reference to the drawings. The whereabouts confirmation system 1 in the present embodiment includes a monitoring device 10, a server 30, and first to fifth portable information terminals 51 to 55 (see FIG. 1). The number of portable information terminals is an example, and is not limited to five. The portable information terminal is not limited to a mobile phone, and may be any terminal that can communicate with the server 30 via a communication carrier network.

  The monitoring device 10 includes a communication unit 11, a control unit 13, an input unit 15, and an output unit 17, and can communicate with the server 30 via the communication unit 11 or the Internet network (a network network of a communication carrier). It is used by a user (hereinafter referred to as “monitorer”) who confirms the position of the portable information terminal to be monitored (first to fifth portable information terminals 51 to 55). The control unit 13 controls each unit of the monitoring device 10 such as a CPU. The input unit 15 is a device for inputting information, such as a keyboard and a mouse. The input unit 15 is a condition for confirming the whereabouts such as monitored portable information terminal information in the whereabouts confirmation program (user of the monitored portable information terminal (hereinafter “monitored” Used to input the action pattern). The output unit 17 is a device that displays character information and map information, such as a monitor, and is used to display position information of a mobile information terminal to be monitored in the whereabouts confirmation program in the present embodiment.

  The server 30 can communicate with the first to fifth portable information terminals 51 to 55 via the network of the communication carrier, and the location confirmation program in the present embodiment is installed in the built-in recording medium (hard disk or the like). ASP (Application Service Provider) server. The monitoring device 10 accesses the server 30 using browser software, and operates the location confirmation program installed in the server 30.

  When the whereabouts confirmation condition (behavior pattern) is set for each portable information terminal (monitored portable information terminal) that confirms whereabouts in the whereabouts confirmation program, a map is displayed on the output unit 17 of the monitoring device 10. . The map displayed on the output unit 17 may be recorded in the monitoring device 10 or may be obtained by downloading from the server 30 or the like.

  While watching the map displayed on the output unit 17, the monitor uses the input unit 15 to input a location confirmation condition (behavior pattern) for each mobile information terminal to be monitored (pattern setting step). The whereabouts confirmation condition (behavior pattern) includes information for identifying a portable information terminal (such as a portable information terminal number) and route setting (or area setting).

  The route setting (or region setting) may be a route calculated based on the starting point and the destination set using the input unit 15, or may be a line on the map using the input unit 15 (see the broken line in FIG. 2). Or by specifying a region (see the dotted line in FIG. 2). Since the route (or area) can be set while viewing the display on the map, there is an advantage that the setting can be made easily.

  In addition, the monitor uses the input unit 15 to set the route (or area) name, the time zone defined by the departure time (or start time) and the arrival time (or end time) for each set route, Set periodic route repeat settings and positioning cycle.

  As an input example in the case of monitoring the process of going from home to school (shown in broken lines in FIG. 2), “monitoring object: first portable information terminal 51”, “route name: attending school”, “departure time: 8 am “10 hours”, “arrival time: 8:30 am”, “repetitive setting of regular route: every Monday to Friday except April” and “positioning cycle: 1 minute” are conceivable.

  In addition, as an input example in the case of monitoring the process of staying in a cram school (displayed with a dotted line in FIG. 2), “monitoring target: second portable information terminal 52”, “area name: learning in a cram school”, “start time: “5:15 pm”, “end time: 6:15 pm”, “regular route repeat setting: every Saturday in April”, “positioning cycle: 10 minutes” are conceivable.

  The information regarding the date and time of the route or area may be further subdivided such as setting the arrival time of the waypoint as well as the departure time (or start time) and arrival time (or end time).

  The whereabouts confirmation condition (behavior pattern) is recorded in the server 30, and the whereabouts confirmation program is executed based on the condition.

  After setting the location confirmation condition (behavior pattern), the server 30 instructs the portable information terminal to be monitored to acquire the position information of the portable information terminal in the designated time zone and in the designated cycle. Is transmitted (position information acquisition instruction step).

  The portable information terminal that has received the signal acquires position information (latitude and longitude information) (position information acquisition step). Specifically, when the portable information terminal is capable of GPS (Global Positioning System) positioning, latitude / longitude information is acquired by GPS positioning, and when the mobile terminal does not have a GPS function or GPS positioning is not possible, If latitude and longitude information is obtained by multiple base station positioning that calculates the position based on radio wave information from the above base stations, and radio wave information from three or more base stations cannot be obtained, from a single base station Latitude / longitude information is acquired by cell-based positioning calculated based on the radio wave information.

  The acquired position information (latitude / longitude information) is transmitted to the server 30 together with information on the positioning method (positioning accuracy).

  The server 30 determines whether or not the mobile information terminal to be monitored is in a location outside the route or area included in the location confirmation condition (behavior pattern) based on the received location information (determination step) ). Specifically, it is determined whether or not the distance between the position of the monitoring target portable information terminal and the set route (or region) exceeds a threshold value. The threshold varies depending on the positioning accuracy of the position information. When the positioning error is small, such as GPS positioning, the threshold is decreased. When the positioning error is large, such as cell-based positioning, the threshold is increased.

  If the distance between the position of the monitored portable information terminal and the set route (or region) does not exceed the threshold, the monitored portable information terminal is included in the whereabouts confirmation condition (behavior pattern). The server 30 is determined to be in a place close to the route or the area (within the predetermined area including the set route or the set area), and the server 30 informs the monitoring device 10 of the position information, positioning accuracy, and monitoring of the portable information terminal to be monitored. Information indicating that the target portable information terminal is within the predetermined area is transmitted.

  The output unit 17 of the monitoring device 10 displays information indicating the position of the mobile information terminal to be monitored as a trajectory (see FIG. 3). Specifically, the output unit 17 displays the position of the mobile information terminal to be monitored as a dot on the map (see black circles t1 to t8 in FIG. 3), and the threshold is centered on the position of the mobile information terminal to be monitored. A circle having a radius is displayed (see dotted lines R6 to R8 in FIG. 3). For example, a black circle t6 indicates a position measured sixth from the starting position, and a dotted line R6 indicates the outline of a circle whose center is the position measured sixth from the starting position and whose threshold is a radius. In FIG. 3, the dotted lines R1 to R5 are omitted, but these may be displayed or may not be displayed.

  When the distance between the position of the monitoring target portable information terminal and the set route (or area) exceeds the threshold, the monitoring target portable information terminal is included in the location confirmation condition (behavior pattern). Alternatively, the server 30 determines that the user is out of the area (is not in the predetermined area including the setting route or the setting area), and the server 30 sends the monitoring device 10 position information, positioning accuracy, The mobile information terminal to be monitored transmits information indicating that it is not within the predetermined area.

  The output unit 17 of the monitoring device 10 displays the route or area included in the setting item and the position information of the mobile information terminal to be monitored in a state where the positioning accuracy is visible on the map. That is, information indicating the position of the mobile information terminal to be monitored is displayed as a locus (see FIG. 4). Specifically, the output unit 17 displays the position of the monitoring target portable information terminal as a dot on the map (see black circles t1 to t10 in FIG. 4), and the threshold value is centered on the position of the monitoring target portable information terminal. A circle having a radius is displayed (see dotted lines R8 to R10 in FIG. 4). For example, a black circle t9 indicates the ninth position measured from the departure position, and a dotted line R9 indicates the outer shape of a circle whose center is the position measured ninth from the departure position and whose threshold is a radius. In FIG. 4, the dotted lines R <b> 1 to R <b> 7 are omitted, but these may be displayed or may not be displayed.

  Further, the output unit 17 outputs information indicating that the monitored portable information terminal is not within a predetermined area including the set route or the set area by voice, text, or video, and the user of the monitoring device 10 (monitoring) Alert the person). In FIG. 4, as an example of the warning display, the location of “Warning! First portable information terminal 51 is off the route of“ Route name: school attendance ”near the dotted line R10. "Is displayed in a balloon.

  At this time, the server 30 transmits information indicating that the monitored portable information terminal is not in the predetermined area including the set route or the set area to the monitored portable information terminal. The mobile information terminal to be monitored outputs information indicating that the mobile information terminal itself is not within the predetermined area by voice, text, or video, and reports to the user (monitored person) of the mobile information terminal to be monitored (warning) (Reporting process).

  In the present embodiment, the user (monitorer) of the monitoring apparatus 10 is in a designated cycle, and the position information and positioning accuracy of the monitoring target portable information terminal, and the monitoring target portable information terminal sets the set route or setting area. It becomes possible to know whether or not the user is within a predetermined area. For this reason, as long as the monitored person holds the monitoring target portable information terminal, the monitoring person can substantially know the movement locus of the monitored person.

  Further, when the position of the monitoring target portable information terminal deviates from the predetermined area including the setting route or the setting area, the name of the setting route or the setting area and the route of the name corresponding to the position of the monitoring target portable information terminal or A warning display indicating that it is out of the area is performed on the monitoring device 10 or the portable information terminal to be monitored. For this reason, even when a plurality of routes or areas are set as the location confirmation conditions (behavior patterns), there is an advantage that such a situation can be easily recognized.

  In addition, in consideration of fluctuations in the error range due to differences in positioning means, it is determined whether or not the position of the mobile information terminal to be monitored has deviated from a predetermined area including the set route or the set area. There is a merit that can be done.

  In addition, since a monitor or the like can manually set a period for acquiring position information or communicating with the server 30 or the monitoring device 10, monitoring is performed in consideration of the communication cost and power consumption of the mobile information terminal to be monitored. It becomes possible to do. For example, if there is a high possibility that the position of the mobile information terminal to be monitored is out of the predetermined area including the set route or the set area, the period is shortened to make monitoring strict, and if the possibility is low, the period is It is conceivable to lengthen and loosen monitoring.

  In addition, since the position information of the monitoring target portable information terminal is displayed on the map with the route or area included in the setting item and the positioning accuracy being visible, the portable information of the monitoring target is also considered in consideration of the positioning error. You can see the positional relationship of the terminal.

  Although the determination of whether or not the position of the mobile information terminal to be monitored is out of the predetermined area including the setting route or the setting area has been described by the position confirmation program installed in the server 30, the monitoring apparatus 10 You may carry out with the program installed in the program installed in the monitoring target portable information terminal.

  Further, the server 30 calculates a position (or an area including the position) where the portable information terminal is expected to move based on the past position information of the monitored portable information terminal, and the predicted position (or predicted) (Region) may be displayed on the map of the output unit 17 of the monitoring device 10 (see the one-dot chain line in FIG. 5).

  Specifically, the server 30 calculates the moving speed and direction (the position with the highest positioning accuracy when there is little movement) from the past position information of the monitoring target portable information terminal, and determines the positioning accuracy. Considering this, the predicted position (or predicted area) is calculated, and the predicted position (or predicted area) is displayed on the map of the output unit 17. The predicted position (or predicted area) is updated every time position information is updated. In this case, the user (monitoring person) of the monitoring device 10 is the action of the user (monitored person) of the monitoring target portable information terminal (whether or not he / she is about to deviate from the set route or area). There is a merit that makes it easier to predict.

  Note that the predicted position (or predicted region) may be shown in a certain size range as shown by the alternate long and short dash line in FIG. 5, or in the form shown by a point such as a star as shown in FIG. Also good. Moreover, the form which displays the positional information actually obtained by positioning simultaneously with these predicted positions (or predicted areas) may also be used. In particular, it is conceivable that the predicted position (or predicted area) is actually more accurate as the position of the mobile phone to be monitored than the position information because the positioning accuracy is low.

  In addition, the server 30 provides an area (destination area) including the destination of the set route, determines whether or not a mobile information terminal to be monitored has entered the destination area, and indicates that it has entered. Information and a destination area may be displayed on the map of the output unit 17 of the monitoring device 10 (see a two-dot chain line and a balloon display in FIG. 7).

  Specifically, the server 30 sets an area (destination area) within a certain range including the destination of the set route, and displays the destination area (two-dot chain line in FIG. 7) on the map. Further, the server 30 determines whether or not the position information of the monitoring target portable information terminal is included inside the destination area. When it is determined that the position information of the monitoring target portable information terminal is inside the destination area, the output unit 17 displays information indicating that the monitoring target mobile phone has entered the destination area on the map. It is displayed on the map (see the balloon display in FIG. 7). In this case, the user (monitoring person) of the monitoring device 10 can know that the user (monitored person) of the mobile phone information terminal to be monitored has reached the destination.

  Note that information such as the time of entering the destination area or the arrival time of the set route may be displayed so that it can be compared with the arrival time at the destination. In addition to the area including the destination (destination area), an area including the waypoint between the departure point and the destination (route point area) is provided, and the mobile information terminal to be monitored is located in the route point area. It may be a form for determining whether or not it has entered.

  In the example of FIG. 7, the output unit 17 displays the position of the monitoring target portable information terminal as a point on the map (see black circles t <b> 1 to t <b> 15), and sets the threshold value around the position of the monitoring target portable information terminal. A circle with a radius is displayed (see dotted lines R13 to R15).

  The destination area (or waypoint area) is not limited to a circle as shown in FIG. 7, but may be another shape. For example, as shown in FIG. 8, a configuration may be adopted in which the destination area is set above (north) above the boundary line of the two-dot chain line. In the present embodiment, since the contents of the setting items can be input on the map displayed on the output unit 17, the circular destination area as shown in FIG. 7 is also determined by the boundary line as shown in FIG. The area can also be easily input.
