Description

  The present invention is a portable terminal capable of acquiring its own current position, a portable terminal position determination method for determining whether there is an abnormality in the behavior of the owner of the portable terminal based on the current position of the portable terminal, The present invention relates to a computer-readable program for making such a determination.

  Currently, portable terminals equipped with GPS (Global Positioning System) and the like and capable of acquiring their current position are in widespread use. There has been proposed a technique for using such a function to cope with a case where a child or an elderly person who is a portable terminal owner gets lost.

For example, in Patent Document 1, an allowable area in which the owner of the mobile terminal is allowed is registered in advance, and if it is determined that the owner of the mobile terminal has left the allowable area using GPS, the mobile terminal Has disclosed a technique for transmitting a notification confirmation signal. According to this technique, when there is no response from the owner, it is determined as an abnormal situation, and predetermined measures such as notifying a third party are taken.
JP 2002-99971 A

  With a technique such as Patent Document 1, it is possible to register a plurality of action ranges in accordance with the schedule (day of the week / time zone) of the portable terminal holder. However, if the action ranges do not overlap, that is, geographically discontinuous, when moving between action ranges, it is determined that the action range is a deviation. As a result, an unnecessary notification operation is performed.

  In view of such a problem, the present invention determines whether or not there is an abnormality in the behavior of the owner of the mobile terminal in the mobile terminal in which a plurality of action ranges corresponding to the schedule of the owner of the mobile terminal are set. It is an object to provide a portable terminal, a portable terminal position determination method, and a program that can be appropriately determined on the assumption of a person's action.

In order to solve the above-described problem, a representative configuration of a mobile terminal according to the present invention stores a current acquisition position of a mobile terminal main body, a first action range , and a second destination serving as a destination. A storage unit that stores the action range in advance, a region interpolation unit that generates an additional action range including a range connecting the two action ranges of the first action range and the second action range , a current position, and 2 A departure determination unit that determines whether or not the owner of the mobile terminal is out of the extended action range based on the extended action range including one action range and an additional action range.

  According to said structure, if two action ranges are memorize | stored in a memory | storage part, the additional action range which will continue in both will be produced | generated automatically between these action ranges. And the area | region where the presence or absence of deviation is determined is an extended action range including an action range and an additional action range. Therefore, even when moving between geographically discontinuous action ranges, it is not determined as a deviation, and unnecessary notification is avoided.

  The storage unit further stores the order of each of the plurality of action ranges, and the region interpolation unit generates an additional action range between each two action ranges in order for three or more action ranges. Then, the departure determination unit may perform the determination by including the three or more action ranges and the additional action range generated between the two action ranges in the extended action range.

  For example, when three destinations in one day are moved in order, three action ranges A to C corresponding to these destinations are set. In order to prevent useless notifications that deviate from the action range when moving between these action ranges, for example, the order of moving in the order of action ranges A, B, and C is determined. It is necessary to keep. In accordance with the order of such movement, an appropriate extended action range in which an additional action range is generated between the action ranges A and B and between the action ranges B and C is completed. No unnecessary additional action range is generated between the action ranges A and C.

  The storage unit further stores a time zone corresponding to each of the plurality of behavior ranges, which determines the order of each of the plurality of behavior ranges, and the departure determination unit corresponds to a time zone to which the determination time point belongs. Generated between the first action range and the second action range having an order before or after the order of the first action range according to the time point when the determination is made, and the first and second action ranges. The added action range may be included in the extended action range for determination.

  According to the above configuration, for example, assuming that the action range A corresponds to the time range 10:00 to 11:00, the action range B 11:00 to 12:00, and the action range C 12:00 to 13:00, the position determination When the point of time is less than 10 o'clock to 10:30, only the action range A is a target for determining whether or not there is a deviation. When the time of position determination is from 10:30 to less than 11:30, the action ranges A and B and the extended action range including the additional action range between them are determined as the presence or absence of deviation. When the position determination time is between 11:30 and less than 12:30, the extended action range including the action ranges B and C and the additional action range between them is a target for determining whether or not there is a deviation. When the time of position determination is from 12:30 to less than 13:00, only the action range C is a determination target of whether or not there is a deviation.

  As described above, according to the time of position determination, the region for which the presence / absence of deviation is determined is sequentially shifted according to the schedule. Therefore, it is possible to perform position determination closer to the actual situation according to the schedule of the portable terminal holder.

  Each of the above time zones is divided into the first half and the second half at an arbitrary time point, and the deviation determination unit determines whether the time point at which the determination is made belongs to the first half or the second half. The action range having the order before or after may be determined as the second action range.

  In the example already described, each 1 hour time zone is divided into the first and second half at 30 minute intervals, but the time of division may be arbitrarily determined. As a result, more detailed schedule management can be performed.

  The portable terminal may further include an action range changing unit that changes the plurality of action ranges and the time zones corresponding to the plurality of action ranges in association with the calendar.

  According to said structure, when the holder of a portable terminal has a schedule which changes in relation to calendars, such as a date and a day of the week, for example, an action range and a time slot | zone can be set according to the schedule.

  The region interpolation unit may generate a region surrounded by two tangent lines that are in contact with both of the two action ranges and the outline of the two action ranges as an additional action range.

  According to said structure, the path | route at the time of trying to move between two action ranges by the shortest possible movement distance will be substantially contained in an additional action range. Therefore, there is a low possibility of erroneous determination that the vehicle has deviated, except for a person who dares to move along an unnatural route.

  The storage unit may further store a movement route connecting two action ranges, and the region interpolation unit may generate a region including the movement route as an additional action range.

  According to said structure, the area | region along movement paths, such as a road and the route of a transportation system, can be made into an additional action range. Especially when moving between action ranges that are far apart, the mobile terminal holder is considered to move using transportation, so those who do not use the assumed transportation are determined to have abnormal behavior It will be.

  The storage unit may further store an action locus that is a history of the current position, and the region interpolation unit may generate a region including the action locus as an additional action range.

  According to said structure, the additional action range can be produced | generated using the locus | trajectory which the portable terminal holder acted in the past. Therefore, it is possible to set an additional action range by moving around by itself without performing an operation such as displaying a map on the display unit and setting an action range. In particular, if you act along a route that moves on a daily basis, the behavior trajectory of the day is recorded, and after that, it is possible to perform position determination using the additional behavior range generated based on the behavior trajectory It becomes. If such an action trajectory is stored in association with a calendar such as a date or day of the week, an additional action trajectory that differs depending on the date or day of the week can be easily set.

In order to solve the above-described problem, a typical configuration of the mobile terminal position determination method according to the present invention stores a first action range in a mobile terminal and stores a second action range as a destination in the mobile terminal in advance. Storing, generating an additional action range including a range connecting the two action ranges of the first action range and the second action range , obtaining the current position of the mobile terminal, the current position, and the two action ranges Based on the extended action range including the additional action range, it is determined whether or not the owner of the mobile terminal is out of the extended action range.

In order to solve the above-described problems, a typical configuration of a program according to the present invention is that a computer stores a position acquisition unit that acquires the current position of a mobile terminal, a first action range , and a first destination that is a destination. A storage unit that stores two action ranges in advance , a region interpolation unit that generates an additional action range including a range connecting the two action ranges of the first action range and the second action range , a current position, Based on the extended action range including the two action ranges and the additional action range, the mobile terminal is made to function as a departure determination unit that determines whether or not the owner of the mobile terminal is out of the extended action range. .

  The component corresponding to the technical idea in the portable terminal mentioned above and its description are applicable also to the said portable terminal position determination method and the said program.

  According to the present invention, in a mobile terminal in which a plurality of action ranges corresponding to the schedule of the owner of the mobile terminal are set, the behavior of the owner is assumed as to whether there is an abnormality in the behavior of the owner of the mobile terminal. Thus, it is possible to provide a mobile terminal, a mobile terminal position determination method, and a program that can be appropriately determined.

In the present embodiment, the GPS acquisition unit 224 is used, but the current position may be acquired based on a signal from the base station 120.

  When it is determined that the owner of the portable terminal 110 has deviated from the predetermined area, the reporting unit 226 calls the telephone number registered as the contact address 236 via the wireless communication unit 222.

(Action range)
FIG. 4 is a diagram schematically showing the action range 230 stored in the memory 212 of FIG. The action range 230 includes, for example, four action ranges 230A, 230B, 230C, and 230D. These action ranges 230 </ b> A to 230 </ b> D are typically areas around the destination of the owner of the mobile terminal 110, and are areas where the owner is supposed to act around the destination.

  When setting the action ranges 230 </ b> A to 230 </ b> D, the map information 238 may be used. According to the map information 238, a point on the map can be specified by longitude and latitude and an address, and can be set as the destination of the holder of the portable terminal 110. Alternatively, on the map information 238 displayed on the display unit 214, the cursor may be moved using the operation unit 216, and an arbitrary point may be specified to be the destination of the owner of the mobile terminal 110.

  When the destination of the holder of the portable terminal 110 is specified, action ranges 230A to 230D may be generated around the destination. The action ranges 230 </ b> A to 230 </ b> D each have a rectangular shape in the present embodiment, but may have a circular shape, an elliptical shape, or the like, and the area may be freely determined.

(Schedule)
FIG. 5 is a diagram illustrating a schedule stored in the memory 212 of FIG. 5A and 5B are schedules 234 and 235 having different dates, respectively, and include the respective orders of the plurality of action ranges 230A to 230D. This order is determined by the time zone corresponding to each of the action ranges 230A to 230D. Although FIG. 5 illustrates a schedule in which all the time zones are continuous, the schedule is not necessarily continuous.

(Behavior range change part)
As shown in FIG. 2, the control unit 210 further includes an action range changing unit 240 that changes a plurality of action ranges included in the schedule and a time zone corresponding to each of the plurality of action ranges in association with the calendar. Yes. For example, the action range changing unit 240 can change the schedules 234 and 235 shown in FIGS. 5A and 5B according to the date and the day of the week. In the example of FIG. 5, the action ranges 230 </ b> A to 230 </ b> D included in the schedules 234 and 235 of different dates are the same, but the order (time period) of moving them is opposite. However, it goes without saying that the present invention is not limited to such an example. You may change to the schedule containing the action range set besides action range 230A-230D shown in FIG. 4, and you may change the time slot | zone corresponding to each action range to a completely different schedule.

  According to the above configuration, when the owner of the mobile terminal 110 has a schedule that changes in relation to a calendar such as a date or a day of the week, the action range and time zone can be set according to the schedule. .

(Region interpolation unit and additional action range)
As illustrated in FIG. 2, the control unit 210 includes a region interpolation unit 242 that generates an additional action range 232 that is continuous between any two action ranges in the action range 230. The additional action range 232 is an area generated by the area interpolation unit 242 based on the action range 230 of FIG.

  As shown in FIG. 4, the region interpolation unit 242 includes two tangents 246 and 248 that are in contact with both of the two action ranges (for example, the action ranges 230A and 230B), and the contour lines of the two action ranges 230A and 230B. A region surrounded by is generated as an additional action range 232A. The additional action ranges 232B and 232C are also generated by this method. The generated additional action ranges 232 </ b> A to 232 </ b> C are stored in the memory 212 as the additional action range 232.

(Deviation determination unit: first operation)
As shown in FIG. 2, the control unit 210 includes a departure determination unit 250. The departure determination unit 250 acquires the current position of the mobile terminal 110 acquired by the GPS acquisition unit 224, an extended action range 252A (described later) including two action ranges (for example, action ranges 230A and 230B) and an additional action range (for example, 232A). 6), it is determined whether or not the holder of the portable terminal 110 has deviated from the extended action range 252A.

(Extended action range)
FIG. 6 is a diagram illustrating an extended action range based on the action range and the additional action range shown in FIG. FIG. 6A shows an extended action range 252A including action ranges 230A and 230B and an additional action range 232A generated therefrom.

  According to the above configuration, if two action ranges, for example, the action ranges 230A and 230B are stored in the memory 212, an additional action range 232A continuous between the two action ranges 230A and 230B is automatically generated. Is done. And the area | region where the presence or absence of the deviation of the holder of the portable terminal 110 is determined is extended action range 252A including action ranges 230A and 230B and additional action range 232A. Therefore, even when moving between geographically discontinuous action ranges 230A and 230B, it is not determined as a departure (lost child), and unnecessary notification is avoided.

  In addition, since the region interpolation unit 242 generates the additional action range 232A using the tangents 246 and 248 (FIG. 4), the path when the user wants to move between the two action ranges 230A and 230B with a movement distance as short as possible. Thus, it is included in the additional action range 232A. Accordingly, when the owner of the mobile terminal 110 tries to move by selecting an unnatural route, it is determined as a departure (lost child), but excluding such a case, the departure from the extended action range 252A is made. Is less likely to be erroneously determined.

  FIG. 6B is a diagram illustrating an extended action range created from three or more action ranges. In the case of the figure, first, the region interpolation unit 242 generates additional action ranges 232A, 232B, and 232C from the four action ranges 230A to 230D. That is, an additional action range is generated between each two action ranges in which the order is continuous. The order in which the region interpolation unit 242 generates the additional action ranges 232A to 232C is arbitrary, and may be generated from any additional action range.

  As described above, in the present embodiment, the method of generating the additional action range follows the time zone (the order of movement) described in the schedule of FIG. For example, if an additional movement range is generated between the action ranges 230A and 230D while ignoring the order of movement, an area that is assumed not to pass through the mobile terminal 110 is not considered a lost area if it enters (an area of deviation) This is because an erroneous determination is likely to occur.

  The departure determination unit includes a mobile terminal for the extended action range 252D illustrated in FIG. 6B (including the four action ranges 230A to 230D and the additional action ranges 232A to 232C generated between the two action ranges). The deviation of 110 owners can be determined. When going back and forth between a number of destinations on a predetermined route throughout the day, it is desirable to determine deviations for such a wide extended action range 252D.

(Additional action range along the movement route)
FIG. 7 is a diagram illustrating an example in which an additional action range is generated in consideration of a movement route between action ranges. The map information 238 stored in the memory 212 of FIG. 2 is GPS map information, and covers road information and routes of transportation. With reference to such map information 238, it is possible to detect a movement route connecting two action ranges. For example, as shown in FIG. 7A, the display screen 214 of the mobile terminal 110 displays an input screen for a railway route name, a boarding station, and a getting-off station. When the holder of the portable terminal 110 makes these inputs, the control unit 210 stores the B station and the C station in the memory 212 as the action range 230. The controller 210 further acquires a route map of the railway line A with reference to the map information 238. The area interpolation unit 242 automatically generates an additional action range 232E including the acquired railway line A and stores it in the memory 212 as the additional action range 232.

  As described above, the region interpolation unit 242 can generate a region along the movement route such as the railway line A or a road as the additional action range 232. The departure determination unit 250 determines the departure of the owner of the mobile terminal 110 for the extended action range 252E including the B station and the C station (action range 230) and the additional action range 232E shown in FIG.

  According to the above configuration, an area along a movement route such as a road or a transportation route can be set as the additional action range 232. Especially when moving between action ranges that are separated from each other, the owner of the mobile terminal 110 is considered to move using transportation, so those who deviate from the assumed transportation route have abnormal behavior, Will be determined appropriately.

(Additional action range along the action trajectory)
FIG. 8 is a diagram illustrating an example in which an additional action range is generated based on a trajectory in which the owner of the mobile terminal 110 has acted. The control unit 210 can acquire the action locus 280 of the owner 270 of the mobile terminal 110 by causing the GPS acquisition unit 224 to periodically acquire the current position of the mobile terminal 110 and tracing it. For example, as shown in FIG. 8A, when there are routes 260A and 260B between the points D and E, if the owner 270 of the mobile terminal 110 selects the route 260A, the action locus along the route 260A is selected. 280 is obtained.

  The memory 212 also stores an action locus 280 that is a history of the current position, and the region interpolation unit 242 generates a region including the action locus 280 as an additional action range 232F as illustrated in FIG. 8B.

  According to said structure, the additional action range 232F can be produced | generated using the action locus | trajectory 280 which the holder 270 of the portable terminal 110 acted in the past. Therefore, the additional action range can be set by moving around without displaying the map information 238 on the display unit 214 and setting the action range as the destination. In particular, if an action is taken along a daily moving route (for example, the route 260A in FIG. 8), the action locus 280 of the day is recorded, and thereafter, an additional action range 232E generated based on the action locus 280 is recorded. It is possible to perform position determination using this. If such an action trajectory 280 is stored for each different date and day of the week, a different additional action range 232 can be easily set according to the calendar.

(Deviation determination unit: second operation)
FIG. 9 is a diagram showing the second operation of the departure determination unit 250 in the present embodiment based on the schedule of FIG. 5A in comparison with time and the extended action range, and FIG. 10 corresponds to FIG. It is a figure which shows the extended action range. The departure determination unit 250 has a first action range corresponding to a time zone to which the determination time point belongs, and a second one having an order before or after the order of the first action range according to the determination time point. The action range and the additional action range generated between the first and second action ranges are included in the extended action range 252 to make a determination.

  According to the above configuration, for example, if the determination time points are 10:00 and 11:00, according to FIG. 5A, these determination time points are the same time zone 9:00 to 12:00. The “first action range” corresponding to this is the action range 230B. However, as shown in FIG. 9, the time zone 9:00 to 12:00 is divided into the first half and the second half at the central time 10:30. The departure determination unit 250 has an action range (action range 230A or 230C) having an order before or after the first action range (action range 230B) depending on whether the time point at which the determination is made belongs to the first half or the latter half. Is determined as the second action range.

  In the example already described, each time zone is divided into the first and second half at the central time, but the time of division may be arbitrarily determined. As a result, more detailed schedule management can be performed. For example, when there is a situation where a certain action range needs to stay for a long time but other action ranges do not need to stay for a long time, it is possible to adjust the staying time in each action range.

  Hereinafter, description will be made by comparing FIG. 5A, FIG. 9 and FIG. According to FIG. 5A, the action range 230A at the time zone 8:00 to 9:00, the action range 230B at the time zone 9:00 to 12:00, and the action range 230C at the time zone 12: 0 to 14:00. Corresponds. As shown in FIG. 9, when the position determination time is between 8:00 and less than 8:30, only the action range 230 </ b> A is a determination target of whether or not there is a deviation. When the position determination time point is less than 8:30 to 10:30, the extended action range 252A including the action ranges 230A and 230B and the additional action range 232A between them is a determination target of whether or not there is a deviation (FIG. 10A When the position determination time is between 10:30 minutes and less than 13:00, the extended action range 252B including the action ranges 230B and 230C and the additional action range 232B between them is a target for determining whether or not there is a deviation (see FIG. 10 (b)) When the position determination time point is less than 13:00 to 14:00, the extended action range 252C including the action ranges 230C and 230D and the additional action range 232C between them is determined as whether or not there is a deviation. (FIG. 10 (c)) When the position determination time is from 14:00 to 15:00, only the action range 230D is a determination target of the presence or absence of deviation.

  As described above, according to the time of position determination, the region for which the presence / absence of deviation is determined is sequentially shifted according to the schedule. Therefore, it is possible to perform position determination closer to the actual situation according to the schedule of the owner of the mobile terminal 110.

  In this embodiment, as shown in FIG. 10, two action ranges are shifted, but three or more action ranges may be shifted.

  Although not shown, if a “notification unit” for notifying the owner 270 of the mobile terminal 110 of the departure is provided, this embodiment can be used not only for lost child determination but also for schedule management. Since the target area for determining whether or not there is a shift shifts over time, if it stays at the current position indefinitely, it will eventually be determined as a deviation because it stays at that location. The owner 270 of the portable terminal 110 knows that the next destination corresponding to the user must hurry.

  The above-mentioned schedule and destination are not limited to the schedule and destination (school, school, etc.) of the mobile terminal owner himself, such as a child who needs lost child determination. It goes without saying that the range of action and the schedule may be set so as to suit the schedule and destination of the guardian accompanying the child. Thereby, a guardian who moves with a child and moves to a plurality of destinations can reduce the labor of constantly monitoring the child so that the child does not get lost at each destination.

(Mobile terminal position determination method)
FIG. 11 is a flowchart showing a mobile terminal position determination method according to the embodiment of the present invention. First, a plurality of action ranges 230 are stored in advance in the mobile terminal 110 (step S300). At this time, a time zone corresponding to the action range 230 is also set, and a schedule as shown in FIG.

  Next, the order according to a time slot | zone is given with respect to several action range 230, and the additional action range 232 continuous to both is produced | generated between each two action ranges (step S310). The generated additional action range 232 is stored in the memory 212, while the schedule is updated for the set action range 230, time zone, and order (step S320).

  Subsequently, the current position of the mobile terminal 110 is acquired (step S330). Then, the process proceeds to position determination. When performing position determination, a schedule is referred to in order to confirm which action range the determination time point belongs to, and which extended action range is a target for deviation determination (step S340). Based on the current position and the extended action range, it is determined whether the holder of the mobile terminal 110 has deviated from the extended action range (step S350). When it deviates, it reports by the report part 226, and when it has not deviated, it returns to the first step S300.
