Next, the operation of the dynamic management monitoring area setting system 1 will be described.
(Moveable area creation process)
The movement management server 10 creates a geofence corresponding to a predetermined route connecting the starting point where the truck 30 travels to the destination. The geofence here defines an area on the road (movable area) in which the truck 30 can travel from the origin to the destination. The place of departure is the site where the transported goods are generated or the place where they are collected, and the destination is the disposal site.

FIG. 3 is a flowchart of a movable area creating process of the activity management monitoring area setting system 1.
First, the route acquisition unit 111 of the movement management server 10 acquires the latitude/longitude information of the starting point and the destination of the truck 30 from the map information storage unit 116 based on the operation input of the administrator or the driver ( Step S11).

  Next, the route acquisition unit 111 creates a route connecting the departure place and the destination (step S12). The route is created using the road network data acquired from the map information storage unit 116. In addition, when creating a route, a route that does not pass through the roads or points is created based on the information of the roads or points where the vehicle carrying the goods cannot travel. Alternatively, it may be created based on movement information when actually traveling from the starting point to the destination. Note that the route is not created by the route acquisition unit 111, but the information of the route created in advance is stored in the map information storage unit 116, and the route acquisition unit 111 acquires the route according to the departure point and the destination. You may do it. It should be noted that when a route connecting the departure place and the destination is created, a route passing through a specific waypoint may be generated. The transit point may be designated when designating the starting point and the destination, or may be automatically set in association with the starting point and the destination.

  Next, the movable area creating unit 112 creates a geofence along the route connecting the starting point and the destination (step S13). As shown in FIG. 4, the movable area creating unit 112 defines the geofence F so as to define a movable area A having a certain road width on the road corresponding to the route R connecting the starting point S and the destination G. Set. The road width of the movable area A is basically set according to the width of the lane in the traveling direction of the road, but may be set wider or narrower than the width of the lane by a certain width. For example, the width of the movable area A may be determined based on the size of the traveling vehicle (here, the truck 30). For example, in the case where the truck 30 is a vehicle as wide as the road width, if the mobile terminal 31 is installed outside the vehicle, the truck 30 is actually in the movable area, The position information detected by the mobile terminal 31 may determine that the user is out of the movable area. Therefore, the width of the movable area A may be set wide according to the size of the track 30.

  Further, the width of the movable area A may be set according to the surrounding environment. For example, when the route passes through a residential area and a private house is built along the road, the width of the movable area A may be set narrow in consideration of noise and safety. Further, the width of the movable area A may be set according to the GPS communication accuracy at that point. As described later, the current position of the mobile terminal 31 is specified based on the position information received by the GPS receiver 32, and it is determined whether or not the truck 30 is traveling within the movable area. Therefore, at a point where the GPS communication accuracy is low, it may be determined that the truck 30 is not present although it is actually in the movable area. Therefore, at a point where GPS communication accuracy is poor, the width of the movable area may be set to be wider so as to mitigate the influence of the error in the position information by GPS. The road width of the movable area does not have to be constant from the starting point to the destination, and can be changed according to the actual road width and the surrounding environment.

  Further, at intersections, branch points, curve points, etc., it is easy for the running vehicle to move left and right. Therefore, at intersections, branch points, curve points, etc., the width of the movable area A should be set wider than that of a straight road. You can

Further, the width of the movable area A and the length (distance) of the section set to the width may be determined according to the legal speed of each road. Specifically, when the legal speed is high, the speed of the traveling vehicle is high, and the amount of left and right movement and the distance traveled are large, so the width of the movable area A is wide and the length of the section is also long. .. On the other hand, when the legal speed is low, the speed of the traveling vehicle is low, and the amount of left and right movement and the distance traveled are also small. Therefore, the width of the movable area A is set to be narrow or standard, Shorten.
Further, in a place where a lane in which a truck can travel is defined, such as an expressway, the width of the movable area A may be set according to the width of the lane in which the truck can travel.

  Further, when there is a rest place such as a parking lot or a convenience store along the road, the width of the movable area A at that point may be set wide. As a result, it is possible to prevent the driver from being determined to have gone out of the movable area when he/she stops at a break while moving. In addition, parking lots and convenience stores that you may drop in while traveling are registered in advance in the external storage device 12, and if those restable facilities exist on the created route, you can move to that point. The width of the area A may be set wider.

  If it is determined that the vehicle has traveled outside the movable area, the traveling record of the truck 30 is analyzed. If the determination is incorrect, the width of the movable area A at the location where the erroneous determination is made is determined from the lane. May be set wide. The determination as to whether or not it is an erroneous determination may be performed by an administrator or the like specifying a point based on the traveling record.

  The width of the movable area A may be set by combining some of the above methods.

  After setting the geofence, the movable area creation unit 112 stores information on the movable area defined by the geofence (polygon data on the map) in the movable area storage unit 117 (step S14). In the movable area storage unit 117, the position information of the starting point and the destination and the information of the movable area are registered in association with the ID of the movable area.

  Through the above procedure, the movement management server 10 creates a movable area when traveling from a certain departure place to a certain destination. In the movable area storage unit 117, for example, information on the movable area along each route from the place where the transported material is generated or the collection place to the plurality of disposal sites is registered.

  The movable area can be generated not only outdoors but also indoors such as in a facility. The indoor movable area can be generated by using the route information inside the facility included in the data regarding the facility. When such route information in the facility is not maintained, it may be generated in advance and stored in the external storage device 12 or the like.

(Movable area setting process)
When the truck 30 starts to carry a transported object, the movement management server 10 sets a movable area for the truck 30 based on the position information at the start.

FIG. 5 is a sequence diagram of a movable area setting process of the movement management monitoring area setting system 1.
When the driver of the truck 30 gets on the truck 30 to transport a transported object, the driver of the truck 30 operates the mobile terminal 31 to perform an operation input indicating transportation start (step S21).

  When the operation input indicating the start of transportation is performed, the mobile terminal 31 acquires the position information via the GPS receiver 32, and transmits the acquired position information and the “movable area setting request” to the movement management server 10. (Step S22).

  When the movement management server 10 receives the position information and the movable area setting request from the mobile terminal 31 in the position information acquisition unit 113, the movable area setting unit 114 refers to the movable area storage unit 117 and receives the received position information. It is confirmed whether or not the movable area including the point indicated by is registered (step S23).

  When the applicable movable area is registered (YES), the movable area setting unit 114 associates the ID of the movable area with the identification information of the mobile terminal 31 and registers it in the monitoring information storage unit 118. (Step S24). Furthermore, the movable area setting unit 114 transmits a “movable area setting completion notification” to the mobile terminal 31 (step S25).

  The mobile terminal 31 receives the movable area setting completion notification from the activity management server 10, and thereafter periodically acquires its own position information via the GPS receiver 32 and transmits it to the activity management server 10.

  In addition, in step S23, when the corresponding movable area is not registered (NO), the standby state is set, and when the truck 30 moves and the position information is received again, the point indicated by the received position information is displayed. If the movable area including is registered, the process proceeds to step S24.

Regarding the setting process of the movable area, a case where there is one corresponding movable area and a case where there are a plurality of applicable movable areas will be described with reference to FIGS.
FIG. 6 is a diagram illustrating an example in which there is one applicable movable area. As shown in FIG. 6, when the three movable areas (E1, E2, E3) registered in the movable area storage unit 117 do not overlap with each other, the movable area including the position of the mobile terminal 31 is There is only one movable area (E1 in the example of FIG. 6) that includes the position P when it is first detected. In such a case, the movable area setting unit 114 associates the movable area E1 with the mobile terminal 31 and registers them in the monitoring information storage unit 118.

  FIG. 7 is a diagram illustrating an example in which there are a plurality of applicable movable areas. As shown in FIG. 7, among the three movable areas (E1, E2, E3) registered in the movable area storage unit 117, if the departure points of the routes corresponding to E1 and E2 are common, Part of E1 and E2 overlap. In such a case, when the mobile terminal 31 departs from the position P during the transportation start operation, E1 and E2 are extracted as the movable areas. In this case, the movable area setting unit 114 registers the movable areas E1 and E2 and the mobile terminal 31 in the monitoring information storage unit 118 in association with each other.

  Note that the means for acquiring the outdoor position information is not limited to the GPS receiver 32 as described above, but may be acquired via a base station with which the mobile terminal 31 communicates, WiFi, or the like. In addition, in the case of acquiring indoor position information, in addition to positioning using WiFi, it can be acquired using means such as BLE (Bluetooth Low Energy) positioning, geomagnetic positioning, and autonomous navigation.

(Dynamic management processing)
The movement management server 10 monitors whether or not the truck 30 is traveling within the set movable area until the truck 30 arrives at the destination.

FIG. 8 is a sequence diagram of the dynamic management process of the dynamic management monitoring area setting system 1.
While the truck 30 is traveling, the mobile terminal 31 periodically acquires its own position information via the GPS receiver 32 and transmits it to the activity management server 10 (step S31).

  When the movement management server 10 receives the position information from the mobile terminal 31 in the mobile body position monitoring unit 115 (step S32: YES), the movement management server 10 refers to the monitoring information storage unit 118 and moves the mobile terminal 31 to the associated movement. It is determined whether or not it exists in the possible area (step S33). When a plurality of linked movable areas are registered, a determination is made for each movable area.

  When the mobile body position monitoring unit 115 determines that the mobile terminal 31 does not exist in the movable area (step S33: NO), the mobile body position monitoring unit 115 informs the mobile terminal 31 and the administrator terminal 20 that the mobile terminal 31 is outside the movable area. Notify (step S34). In addition, when a plurality of linked movable areas are registered, when the mobile terminal 31 does not exist in any of the movable areas, the fact that the user is outside the movable area is notified. Further, the notification may be sent to the terminals held by other parties.

  When it is determined that the mobile terminal 31 exists in the movable area (step S33: YES), it is determined whether or not there are a plurality of movable areas that have been set, and when there are a plurality of movable areas (step S35: YES), It is confirmed whether or not there is a movable area in which the mobile terminal 31 does not exist in the area (step S36). When there is a movable area in which the mobile terminal 31 does not exist (step S36: YES), the linking between the corresponding movable area and the mobile terminal 31 is released (step S37). The activity management server 10 repeats the above processing until the truck 30 arrives at the destination.

  The mobile terminal 31 and the administrator terminal 20 that have received the notification that the mobile terminal 31 is outside the movable area notify that the mobile terminal 31 has moved out of the movable area (step S38). Specifically, a warning message as shown in FIG. 9 may be displayed on the display of the terminal or a voice warning message may be output.

  If there are a plurality of movable areas associated with the mobile terminal 31, the number of associated movable areas may be held in the monitoring information storage unit 118. When the mobile body position monitoring unit 115 determines that the mobile terminal 31 has moved out of one movable area, the number of linked movable areas is reduced by one, and the number of linked movable areas is zero. When it becomes, it may be determined that the mobile terminal 31 does not exist in the movable area.

  As described above, according to the present embodiment, since the movable area is created along the route connecting the starting point and the destination, the monitoring target such as the truck is the route determined from the starting point to the destination. You can manage whether you are moving along.

Moreover, since the road width of the movable area is determined according to the size of the monitoring target, it is possible to cope with vehicles of any size.
Further, since the road width of the movable area is determined according to the surrounding environment, the setting can be made in consideration of the surrounding buildings and the like.
Further, since the road width of the movable area is determined according to the communication condition such as the reception accuracy of the surrounding GPS, it is possible to mitigate the influence of the error of the position information due to the poor communication accuracy.
