The control unit 70a is, for example, an integrated circuit such as an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA), or an electronic circuit such as a central processing unit (CPU) or a micro processing unit (MPU). .

  In addition to the scheduled location of the monitored person and the date and time when the monitored person stays at the planned location, the schedule storage unit 61a allows the monitored person to stay on the route for movement when moving The relevant position of the destination to be moved is stored. FIG. 11 is a diagram for explaining the schedule storage unit 61a.

  As illustrated in FIG. 11, the schedule storage unit 61 a stores a schedule in which a schedule start date / time, a schedule end date / time, a position, and a movement allowable position are associated with each employee ID. Here, the “movement allowable position” is a related position of a movement destination that allows the monitored person to stay on the moving route. The “employee ID”, “schedule start date / time”, “schedule end date / time”, and “position” are the same as those shown in FIG.

  For example, as illustrated in FIG. 11, the schedule storage unit 61 a stores “schedule start date and time: 200091260900, schedule end date and time: 200911261700, position: Sendai branch” in association with “employee ID: 2”. Further, the schedule storage unit 61a stores “movement allowable position: AA Trading, BB Company” in association with “Employee ID: 2”. In other words, the above-described schedule indicates that the employee of “employee ID: 2” is “Sendai” from “9:00” on “November 26, 2009” to “17:00” on “November 26, 2009”. It means staying at a "branch".

  Further, the above-described schedule means that the employee of “employee ID: 2” is allowed to stay on a route moving between “Sendai branch” and “AA trading company”. Further, the above-described schedule means that an employee with “employee ID: 2” is allowed to stay on a route that travels between “Sendai branch” and “BB company”. In addition, the above-described schedule means that an employee with “employee ID: 2” is allowed to stay on a route moving between “AA Trading” and “BB Company”.

  Similarly, the schedule storage unit 61a stores “schedule start date / time: 200911260900, schedule end date / time: 200911261700, position: company” in association with “employee ID: 1”. Furthermore, the schedule storage unit 61a stores “movement allowable position: −” in association with “employee ID: 1”. Note that “-” shown in “movement allowable position” means that the monitored person is not allowed to stay on the moving route.

  Returning to FIG. 10, the intermediate area storage unit 64 stores the intermediate area calculated by the intermediate area calculation unit 77 described later. Specifically, the intermediate area storage unit 64 stores an intermediate area that is an area that is allowed to stay from the position before the movement to the position after the movement when the monitored person moves. .

  FIG. 12 is a diagram for explaining the intermediate area storage unit 64. As illustrated in FIG. 12, the intermediate area storage unit 64 stores a position, a center point, an allowable range, and a monitoring interval in association with each other. Here, “position” means a position before the movement of the monitored person and a position after the movement. “Center point, latitude” means the latitude of the center of the intermediate area. “Center point, longitude” means the longitude of the center of the intermediate area. The “allowable range” means a distance from the center point that allows the monitored person to stay. The “monitoring interval” means a time interval at which the mobile phone 10a acquires the current position of the monitored person.

  For example, as shown in FIG. 12, the intermediate area storage unit 64 associates “location: Sendai branch-AA trading company” with “center point, latitude: N38 ° 18′22 ″” and “center point, longitude. : E140 ° 52′32 ″ ”and“ allowable range: 2000 m ”are stored. Further, as shown in FIG. 12, the intermediate area storage unit 64 stores “monitoring interval: 30 minutes” in association with “position: Sendai branch—AA trading company”.

  In other words, the above-mentioned information shows that the intermediate area when moving between “Sendai Branch” and “AA Trading” is centered on “38 ° 15′18 ″ north latitude and 140 ° 52′32 ″ east longitude”. , The area is within “2000 m”. Further, the above-described information means that the current position of the monitored person is acquired at intervals of “30 minutes” when the monitored person is in the above-described intermediate area. Although not shown, the intermediate area storage unit 64 stores information on the intermediate area between “position: Sendai branch” and “movement allowable position: BB company” and “movement allowable position: AA Trading” shown in FIG. ”And“ moveable position: company BB ”is stored.

  The intermediate area calculation unit 77 calculates a minimum circular area that includes an allowable area at any two positions of the planned location and the related position as an intermediate area between the two positions. Specifically, the intermediate area calculation unit 77 refers to the “position” and “movement allowable position” of the monitored person's schedule stored by the schedule storage unit 61a, and includes an intermediate area including the allowable areas of the two positions. Is calculated.

  FIG. 13 is a diagram for explaining an example of the intermediate area calculation process. Here, an area E11 shown in FIG. 13 indicates an allowable area for “AA Trading”. An area E12 illustrated in FIG. 13 indicates an allowable area of “Sendai branch”. In addition, regions other than the region E11 and the region E12 in the region E10 illustrated in FIG. 13 indicate intermediate regions. A line L10 illustrated in FIG. 13 indicates a straight line that passes through the central point “a” of “AA Trading” and the central point “b” of “Sendai Branch”. Hereinafter, a case where an intermediate area between “position: Sendai branch” and “movement allowable position: AA Shoji” of the employee of “employee ID: 2” shown in FIG. 11 will be described with reference to FIG.

  First, the intermediate area calculation unit 77 calculates the intersection of the line L10 passing through the center point “a” of the area E11 and the center point “b” of the area E12, and the area E11 and the area E12. Then, the intermediate area calculation unit 77 extracts two points with the longest distance between the calculated intersections. That is, the intermediate area calculation unit 77 extracts the points “d” and “c” shown in FIG. Then, the intermediate area calculation unit 77 calculates a point “e” that is an intermediate point between the extracted point “d” and the point “c” as a central point, and stores the calculated central point in the intermediate area storage unit 64. .

  The intermediate area calculation unit 77 calculates the distance from the calculated center point “e” to the point “d” or the point “c” as an allowable range, and stores the calculated allowable range in the intermediate area storage unit 64. Similarly, the intermediate area calculation unit 77 includes an intermediate area between “position: Sendai branch” and “movement allowable position: BB trading”, and “movement allowable position: AA trading” and “movement allowable position: BB company”. The intermediate region is calculated.

  The time measuring unit 73a measures time based on the monitoring interval stored by the intermediate region storage unit 64 when it is determined by the matching unit 75a described later that the monitored person is staying in the intermediate region. The measurement result is notified to the transmission / reception unit 74. For example, if it is determined that the employee of “employee ID: 2” shown in FIG. 11 is staying in an intermediate area between “Sendai branch” and “AA trading company”, the time measuring unit 73a displays in FIG. Referring to the “monitoring interval” shown, the transmission / reception unit 74 is notified that the time has passed every “30 minutes”.

  When the current position acquired by the transmission / reception unit 74 does not match any of the planned position and the related position, the collation unit 75a determines that the current position is an intermediate position between any two of the planned position and the related position. Check whether it is included in the area. Furthermore, when the current position acquired by the transmission / reception unit 74 is included in the intermediate region of any two positions among the planned location and the related position, the collation unit 75a has a time included in the intermediate region equal to or longer than a predetermined time. It is further determined whether or not to continue.

  Specifically, the collation unit 75a includes the current position in the intermediate area when the current position of the monitored person is not included in either the allowable area of the schedule position or the allowable area of the position corresponding to the related ID. Check whether or not If the current position of the monitored person is included in the intermediate area, the collation unit 75a determines that the current position of the monitored person acquired based on the monitoring interval stored by the intermediate area storage unit 64 is intermediate. It is determined whether it is included in the area.

  For example, when monitoring the position of the employee with “employee ID: 2”, the collation unit 75a first sets the current position of the employee with “employee ID: 2” as “Sendai branch”, “AA trading” and “BB”. It is determined whether it is included in any of the allowable areas of “Company”. Then, when the current position of the employee of “employee ID: 2” is not included in any of the allowable areas, the collation unit 75a determines that the current position of the employee of “employee ID: 2” is in the middle area of each position. It is determined whether or not it is included.

  Here, when the current position of the employee of “employee ID: 2” is included in the intermediate area shown in FIG. 13, the collation unit 75a is based on the notification for every “30 minutes” of the time measurement unit 73a. Then, it is determined whether or not the current position acquired by the transmitting / receiving unit 74 is included in the intermediate area shown in FIG.

  Returning to FIG. 10, the output control unit 76 a controls the output unit 50 to output a warning when it is determined that the current position is not included in the intermediate region as a result of the collation by the collation unit 75 a. Further, the output control unit 76a controls the output unit 50 to output a warning when it is determined that the time included in the intermediate region continues for a predetermined time or more.

  Specifically, the output control unit 76a outputs a warning when the collation unit 75a determines that the monitored person is not in any of the allowable area of the schedule position, the allowable area of the related position, and the intermediate area. Thus, the output unit 50 is controlled. For example, the output control unit 76a includes the latitude and longitude of the current position of the employee of “employee ID: 2” in any of the allowable or intermediate areas of “Sendai branch”, “AA trading company”, and “BB company”. The output unit 50 is controlled to output a warning when it is determined that it is not.

  Further, the output control unit 76a controls the output unit 50 to output a warning when the collation unit 75a determines that the monitored person is in the intermediate area for a predetermined time or more. For example, the output control unit 76a causes the output unit 50 to output a warning when an employee of “employee ID: 2” stays in an intermediate area of “Sendai branch-AA trading” for “30 minutes” or more. Control.

  Next, a processing procedure performed by the mobile communication device according to the third embodiment will be described. In the following, first, the procedure of the intermediate area calculation process performed by the mobile communication device according to the third embodiment will be described, and then the procedure of the position monitoring process performed by the mobile communication device according to the third embodiment will be described.

[Procedure for Intermediate Region Calculation Processing by Mobile Communication Device According to Embodiment 3]

As shown in FIG. 14, first, when a movement allowable position is set in the schedule storage unit 61a (Yes in Step S401), the intermediate area calculation unit 77 generates a straight line passing through the center point of the two positions (Step S401). S402).

  Then, the intermediate area calculation unit 77 calculates the intersection between the generated straight line and the allowable area at the two positions (step S403). Thereafter, the intermediate area calculation unit 77 extracts the intersection having the longest distance between the calculated intersections (step S404), calculates the center point and the allowable range (step S405), and calculates the calculated center point and the allowable range. The intermediate area is stored in the intermediate area storage unit 64 (step S406). If the movement allowable position is not set in the schedule storage unit 61a (No at Step S401), the intermediate area calculation unit 77 enters a standby state.

[Procedure for Position Monitoring Processing by Mobile Communication Device According to Embodiment 3]
FIG. 15 is a diagram for explaining the procedure of the position monitoring process performed by the mobile communication device according to the third embodiment. As shown in FIG. 15, when the latitude and longitude of the current position of the monitored person are included in the intermediate area (Yes at Step S501), the time measuring unit 73a starts time measurement (Step S502), It is determined whether or not the time elapses (step S503). Specifically, the time measuring unit 73a determines whether or not the monitoring interval time stored by the intermediate area storage unit 64 has elapsed.

  When a predetermined time has elapsed (Yes at Step S503), the transmission / reception unit 74 transmits a positioning request to the monitored person's mobile phone (Step S504). When the positioning result is received from the monitored person's mobile phone (Yes at step S505), the collation unit 75a collates the positioning result with the intermediate area (step S506), and whether or not the positioning result is included in the intermediate area. Is determined (step S507). Note that the mobile phone 10 is in a standby state until it receives a positioning result (No at step S505).

  Here, when the positioning result is included in the intermediate region (Yes at Step S507), the output control unit 76a controls the output unit 50 to start an abnormal alarm (Step S510), and ends the process. . On the other hand, when the positioning result is not included in the intermediate area (No at Step S507), the collation unit 75a determines whether the positioning result is included in the allowable area (Step S508).

  Here, when the positioning result is not included in the allowable region (No at Step S508), the output control unit 76a controls the output unit 50 to start an abnormal alarm (Step S510), and ends the process. . On the other hand, when the positioning result is included in the allowable region (Yes at Step S508), the mobile phone 10a continues monitoring (Step S509).

  Then, the time measuring unit 73a determines whether or not the end date / time of the schedule has been reached (step S511). If the end date / time has not been reached (No at step S511), the process returns to step S509 to continue monitoring. . On the other hand, when the end date / time is reached (Yes at step S511), the mobile phone 10 ends the process.

  In step S501, if the current position is not included in the intermediate region (No in step S501), the output control unit 76a controls the output unit 50 to activate an abnormal alarm (step S510), and the process Exit. That is, when it is determined that the current position of the monitored person is not in any of the allowable area of the schedule position, the allowable area of the related position, and the intermediate area, the output control unit 76a controls the output unit 50, Activate an abnormal alarm.
