That is, in the history information 244, whether or not the first terminal has moved and the state related to the movement (train movement state, bicycle movement state, walking state, stop state, or stationary state) are time information and position information. Recorded in association. That is, the history information 244 records the time that the first terminal has moved in the past, the time that the first terminal has not moved, and the time that has been in each state related to movement.

  Next, the abnormality determination unit 253 compares the received movement information and time information with the condition information 241 stored in the server storage unit 24 in association with the identification numbers and addresses of the mobile terminals 1a and 1b. The abnormality determination unit 253 determines whether the time information indicates the time set in the schedule 242 and whether the movement information indicates a state other than the state set for the time in the schedule 242. Then, the time information is compared with the schedule 242 included in the condition information 241 (step S305). The schedule 242 stored in the server storage unit 24 is set in advance by the mobile terminal 1b.

  FIG. 7 shows an example of a schedule setting screen for setting a schedule 242 related to the mobile terminal 1a displayed on the mobile terminal 1b.

  A schedule setting screen 700 shown in FIG. 7 is a screen for setting a schedule for the user of the mobile terminal 1a (the child of the user of the mobile terminal 1b). In the example shown in FIG. 7, a schedule for each day of the week and time can be set at intervals of 10 minutes. The interval for setting the schedule is not limited to 10 minutes, but may be other intervals such as 30 minutes, 60 minutes, etc., and may be set to an arbitrary interval by the user. As the schedule, any one of states related to movement (train movement state, bicycle movement state, walking state, stop state, or stationary state) is set. As a schedule, it may be set whether or not the mobile terminal 1a is moving at each time.

  In the example shown in FIG. 7, from Monday to Friday, since the child is taking classes at school, the schedule until 14:50 is set to a stationary state. On Mondays, Wednesdays, and Fridays, after the class is over, the child walks home, so the schedule from 15:00 to 15:20 is set to walking, and the schedule after 15:30 is set to stationary. The On the other hand, on Tuesdays and Thursdays, the children go to the cram school on the train after the class is finished, so the schedule from 15 o'clock to 15:20 is in the train moving state, from 15:30 to 16:30 The schedule is set to the stationary state, and the schedule from 16:40 to 17:00 is set to the train moving state. Also on Saturdays, the children go to the cram school on the train, so the schedule from 14:00 to 14:20 is in the train moving state, the schedule from 14:30 to 16:30 is in the stationary state, 16:00 The schedule from 40 minutes to 17:00 is set to the train movement state. On Sundays, since the child is at home, the schedule from 14:00 to 17:00 is set to a stationary state.

  In addition, since an error occurs depending on the date when each schedule is switched, no schedule is set at the timing when the schedule is switched from 14:50 to 15:00 from Monday to Friday.

  In the example shown in FIG. 7, only one state is set as a schedule for each time, but a plurality of states (for example, a stationary state and a stopped state, or a walking state, a bicycle moving state, and a train moving state) Etc.) may be set simultaneously.

  When the setting button on the schedule setting screen is pressed, the display control unit 186 of the portable terminal 1b sends all combinations of the time when the schedule is set and the state set at that time via the terminal communication unit 11 2 to send. On the other hand, when the terminal processing unit 18 of the server 2 receives the combination of time and state from the mobile terminal 1b via the server communication unit 21, the received time and state combination is used as the identification number of the mobile terminal 1a and the mobile terminal 1b. And stored in the schedule 242 of the server storage unit 24 in association with the address.

  Next, when the time information does not indicate the time set in the schedule 242 or when the movement information indicates a state set for the time in the schedule 242 (step S305-No), It is determined that no abnormality has occurred in the user carrying the portable terminal 1a (step S306). In this case, the abnormality determination unit 253 does not perform any particular process and moves the process to step S309.

  On the other hand, when the time information indicates the time set in the schedule 242 and the movement information indicates a state other than the state set for the time in the schedule 242 (step S305-Yes), the abnormality determination unit 253 It is determined that an abnormality has occurred in the user who carries the terminal 1a (step S307). In this case, the abnormality notification unit 254 notifies abnormality information indicating an abnormality of the user carrying the portable terminal 1a to the portable terminal 1b via the server communication unit 21 (step S308), and the process proceeds to step S309.

  In the present embodiment, the time set in the schedule 242 is a time zone having a predetermined time width, and the abnormality determination unit 253 is included in the time zone set in the schedule 242. If it is determined that the time information indicates the time set in the schedule 242. In addition, when the movement information does not match any of the states set in the time period in the schedule 242, the abnormality determination unit 253 displays a state other than the state in which the movement information is set for the time in the schedule 242. It is determined to be shown.

  Next, the server processing unit 25 waits until a predetermined time (for example, 10 seconds) elapses (step S309-No). When the predetermined time elapses (step S309-Yes), the server processing unit 25 proceeds to step S301 and repeats the step. The processes of S301 to S309 are repeated. Thereby, the information acquisition part 251 acquires movement information, time information, and position information regularly, and determines whether abnormality generate | occur | produced in the user who carries the portable terminal 1a.

  In step S <b> 305, the abnormality determination unit 253 may compare the received movement information and time information with the restriction 243 included in the condition information 241 stored in the server storage unit 24. This restriction 243 is preset by the portable terminal 1b.

  FIG. 8 shows an example of a restriction setting screen for setting a restriction 243 related to the portable terminal 1a displayed on the portable terminal 1b.

  A restriction setting screen 800 shown in FIG. 8 is a screen for setting an upper limit of the length of time that each state related to the movement of the user of the mobile terminal 1a (the child of the user of the mobile terminal 1b) may continue. . In the example shown in FIG. 8, the length of time can be set for each state. A plurality of states may be collectively set as one state. For example, the length of time during which the mobile terminal 1a is moving (train movement state, bicycle movement state and walking state) or the time period during which the mobile terminal 1a is not moving (stop state and stationary state) can be set together. it can.

  As shown in FIG. 8, for example, when the parent wants to know that the portable terminal 1b has been lost, the child can lose the portable terminal 1b by setting the upper limit of the stationary time to 180 minutes. If 1b is stationary for 180 minutes or more, a notification is made to the parent mobile terminal 1a. For example, when the child wants to limit the time for which the mobile terminal 1b is used, the child is using the mobile terminal 1b continuously for 10 minutes or more by setting the upper limit of the stop time to 10 minutes. The parent mobile terminal 1a is notified. For example, if the child does not plan to take the train continuously for 30 minutes or longer, the upper limit of the train moving state time is set to 30 minutes so that the child can take the mobile terminal 1b to the train for 30 minutes or longer continuously. When it is on the vehicle, the parent mobile terminal 1a is notified.

  In the example shown in FIG. 8, the walking state and the bicycle moving state are not set because the upper limit of the continuous time length cannot be assumed.

  When the setting button on the restriction setting screen 800 is pressed, the display control unit 186 of the portable terminal 1b sends the combination of the state and the time length via the terminal communication unit 11 for each state in which the time length is set. To the server 2. On the other hand, when the terminal processing unit 18 of the server 2 receives the combination of the state and the length of time from the portable terminal 1b via the server communication unit 21, the received combination of the state and the length of time is converted to the portable terminal 1a and The information is stored in the restriction 243 of the server storage unit 24 in association with the identification number and address of the portable terminal 1b.

  In step S305, the abnormality determination unit 253 indicates the state indicated in the received movement information based on the received movement information and time information and the movement information and time information stored in the server storage unit 24 in step S303. Calculate the length of time that is continuous. The abnormality determination unit 253 determines whether or not the calculated time length is equal to or longer than the length of time that the state stored in the restriction 243 is longer than the movement information and time information. 243 is compared. If the calculated time length is less than the time length stored in the limit 243, the abnormality determination unit 253 determines that no abnormality has occurred in the user and stores the time stored in the limit 243. If it is equal to or longer than the length of the user, it is determined that an abnormality has occurred in the user.

  In addition, as described above, the abnormality determination unit 253 determines for each collected state when the mobile terminal 1a is moving or is not moving as one state. I do. In this case, when the movement information indicates that the movement information is moving, the abnormality determination unit 253 calculates the length of time continuously indicating that the movement information is moving. On the other hand, when the movement information indicates that the movement information has not moved, the abnormality determination unit 253 calculates the length of time continuously indicating that the movement information has not moved. The abnormality determination unit 253 determines whether or not an abnormality has occurred in the user based on whether or not the calculated length of time is equal to or longer than the length of time that each state stored in the limit 243 is continuous. To do.

  As a result, the parent can easily set the conditions for receiving the notification without setting the child's schedule in detail.

  In addition, the upper limit of the length of time that each state continues is not set by each user, but may be set in advance for all users. This eliminates the need for the user to set any conditions for receiving notifications, improving convenience.

  In step S <b> 305, the abnormality determination unit 253 may compare the received movement information and time information with the history information 244 included in the condition information 241 stored in the server storage unit 24. For example, the abnormality determination unit 253 uses the time during which the mobile terminal 1a has moved at a predetermined ratio (for example, 80%) or more of the information recorded as the history information 244, and the movement information and the time information. Make a comparison. In the history information 244, the abnormality determination unit 253 calculates a rate at which the mobile terminal 1a has moved for each time zone having a predetermined time width, and extracts a time zone in which the calculated rate is equal to or greater than the predetermined rate. . The abnormality determination unit 253 determines whether or not the time information indicates a time within any time zone extracted and the movement information does not move. The abnormality determination unit 253 determines that no abnormality has occurred in the user when no time within any time zone extracted by the time information is indicated, or when the movement information indicates that the movement is moving. On the other hand, the abnormality determination unit 253 determines that an abnormality has occurred in the user when the time information indicates a time in any time zone and the movement information does not move.

  In addition, the abnormality determination unit 253 compares the movement information and the time information by using the time when the mobile terminal 1a is moving at a predetermined ratio or more, not the time when the mobile terminal 1a is moving at a predetermined ratio or more. You may go. In that case, the abnormality determination unit 253 calculates the ratio of each recorded state (train movement state, bicycle movement state, walking state, stop state, or stationary state) for each time period in the history information 244, and calculates A combination of a time zone and a state in which the ratio is equal to or greater than a predetermined ratio is extracted. The abnormality determination unit 253 determines whether or not the time information indicates a time within a time zone related to any combination and the movement information indicates a state other than a state corresponding to the time zone. The abnormality determination unit 253 determines that no abnormality has occurred in the user when the time information does not indicate a time within the time zone corresponding to any combination, or when the movement information indicates a state corresponding to the time zone. . On the other hand, the abnormality determination unit 253 determines that an abnormality has occurred in the user when the time information indicates a time within a time zone related to any combination and the movement information indicates a state other than a state corresponding to the time zone. To do.

  Thereby, the parent can grasp that when the child is taking an action different from normal.

  Note that the abnormality determination unit 253 may individually calculate the ratio of each state in each time zone for each day of the week. Moreover, the abnormality determination part 253 may calculate the ratio of each state in each time zone based on a history within a recent predetermined period (for example, three months). Further, the abnormality determination unit 253 may change the predetermined ratio for each date and / or state. Thus, the abnormality determination unit 253 can detect with high accuracy that the child is taking an action different from normal.

  In step S305, when the time information indicates the time set in the schedule 242 and the movement information indicates a state other than the status set for the time in the schedule 242, the abnormality determination unit 253 further receives a reception. It may be determined whether the position indicated in the position information is a preset position (for example, a station). In that case, the abnormality determination unit 253 determines that an abnormality has occurred in the user carrying the mobile terminal 1a only when the position indicated by the received position information is a preset position, and the received position information When the position shown is not a preset position, it is determined that no abnormality has occurred in the user who carries the mobile terminal 1a.

  The abnormality determination unit 253 receives a geofencing technique when a virtual fence is installed on a map and the position indicated by the position information received from the mobile terminal 1a is within a specific fence. It is determined that the position indicated in the position information is a preset position. Thereby, the abnormality determination part 253 can determine more accurately whether the child is in a dangerous state.

  Furthermore, the abnormality determination unit 253 may determine whether or not the user carrying the mobile terminal 1a is near the user carrying the mobile terminal 1b. If the user is nearby, the abnormality determination may not be performed. In that case, the abnormality determination unit 253 periodically acquires position information from the mobile terminal 1 b via the server communication unit 21 and stores it in the server storage unit 24. In step S304, after the history recording unit 252 records the movement information, time information, and position information in the history information 244, the abnormality determination unit 253 determines that the position indicated by the position information acquired from the mobile terminal 1a is the mobile terminal 1b. It is determined whether or not it is in the vicinity of the position indicated by the position information acquired from the above. When the position of the mobile terminal 1a is in the vicinity of the position of the mobile terminal 1b, the abnormality determination unit 253 does not perform the abnormality determination shown in step S305, and returns the process to step S301. Thereby, the abnormality determination part 253 can suppress erroneously determining that an abnormality has occurred in the child when the child is in the same location as the parent.

  The server 2 also functions as a Web server and provides the mobile terminal 1b with a Web screen that displays the current state of the user of the mobile terminal 1a in accordance with a request from the mobile terminal 1b.

  The terminal storage unit 17 of the portable terminal 1b stores a URL (Uniform Resource Locator) for Web access to the server 2 that is determined for each user. When receiving a user instruction via the terminal operation unit 12, the display control unit 186 accesses the URL stored in the terminal storage unit 17 via the terminal communication unit 11.

  On the other hand, when the web control unit 255 of the server 2 accepts access from the mobile terminal 1b via the server communication unit 21, the latest movement information and position of the user of the mobile terminal 1a stored in the server storage unit 24 Web page information indicating the movement information and position information is generated from the information. Then, the Web control unit 255 transmits the generated Web page information to the mobile terminal 1b via the server communication unit 21.

  When receiving the Web page information from the server 2 via the terminal communication unit 11, the display control unit 186 of the portable terminal 1 b displays a Web screen based on the received Web page information on the terminal display unit 13.

  FIG. 9 shows an example of a screen that displays the movement information of the mobile terminal 1a displayed on the mobile terminal 1b.

  A movement state screen 900 shown in FIG. 9 is a screen for displaying movement information of the mobile terminal 1a. As shown in FIG. 9, a map is displayed on the movement state screen 900, and the position where the user of the portable terminal 1a exists on the map is displayed as “◯”. The web control unit 255 of the server 2 generates web page information so as to change the display mode of the position where the user carrying the mobile terminal 1a is present depending on the state of the mobile terminal 1a. The web control unit 255 sets the position to “◯” when the mobile terminal 1a is in a stationary state, sets the position to “△” when the mobile terminal 1a is in a stopped state, and sets the position to “ □ ”, the position is“ × ”when the bicycle is moving, and the position is“ ☆ ”when the train is moving. The web control unit 255 displays the position in blue when the mobile terminal 1a is in a stationary state, displays the position in green when the mobile terminal 1a is in a stopped state, and displays the position when in a walking state. May be displayed in yellow, the position may be displayed in orange when the bicycle is moving, and the position may be displayed in red when the train is moving.
