Next, the operation of the movement management system 1 will be described.
(Moveable area creation processing)
The movement management server 10 creates a geofence corresponding to a predetermined route connecting the departure place where the truck 30 travels to the destination. Here, the geofence defines an area (movable area) on the road where the truck 30 can travel from the departure point to the destination. The departure place is the place where the cargo is generated, the place where it is accumulated and the like, and the destination is the disposal place and the like.

FIG. 3 is a flowchart of movable area creation processing of the movement management system 1.
First, the route acquisition unit 111 of the movement management server 10 acquires latitude / longitude information of the departure place and the destination of the track 30 from the map information storage unit 116 based on the operation input by the administrator, the driver, etc. 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. Also, 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 can not travel. Alternatively, it may be created based on movement information when actually traveling from the departure place to the destination. In addition, the route is not created by the route acquisition unit 111, but information on the route created in advance is stored in the map information storage unit 116, and the route acquisition unit 111 acquires a route according to the departure place and the destination. You may do so. In addition, when creating a route connecting the departure point and the destination point, it is possible to set a route passing through a specific via point. The transit point may be designated when specifying the departure point and the destination, or may be automatically set in association with the departure point and the destination.

  Next, the movable area creation unit 112 creates a geofence along the route connecting the departure place and the destination (step S13). The movable area creation unit 112, as shown in FIG. 4, places 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 departure place S and the destination G. Set The road width of the movable area A is basically set in accordance with 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 (in this case, the truck 30). For example, in the case where the truck 30 is a vehicle having a width as wide as the road width, if the mobile terminal 31 is installed on the outer side of the vehicle, the truck 30 is actually in the movable area. Depending on the position information detected by the mobile terminal 31, it may be determined that the mobile terminal 31 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.

  Also, 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. Also, the width of the movable area A may be set according to the communication accuracy of the GPS 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 the track 30 is traveling in the movable area. For this reason, it may be determined that the track 30 is not present at a point where the GPS communication accuracy is low although the track 30 is actually in the movable area. For this reason, at a point where the communication accuracy of the GPS is poor, the width of the movable area may be set wider to mitigate the influence of the error of the position information by the GPS. The road width of the movable area does not have to be constant from the place of departure to the destination, and can be changed according to the actual width of the road and the surrounding environment.

  In addition, at an intersection, a branch point, a curve point, etc., a traveling vehicle can easily move to the left or right. Therefore, the width of the movable area A is set wider than a straight road at an intersection, a branch point, a curve point, etc. You may

Also, the width of the movable area A and the length (distance) of the section to be set to the width may be determined according to the legal speed of each road. Specifically, when the legal speed is fast, the speed of the traveling vehicle is high, and the amount of movement to the left and right and the traveling distance become large. . On the other hand, when the legal speed is slow, the speed of the vehicle traveling is slow, and the amount of movement to the left and right and the traveling distance are also small, so the width of movable area A is set narrow or standard Should be short.
Also, where a lane where 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 travelable lane.

  If there is a rest area 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, when the driver stops by while traveling, it can be avoided that it is determined that the driver has moved out of the movable area. In addition, a parking lot and a convenience store that you may stop while traveling are registered in advance in the external storage device 12, and if there is a restable facility on the created route, it is possible to move the point The width of the area A may be set wide.

  If it is determined that the vehicle has traveled outside the movable area, the traveling record of the track 30 is analyzed, and if the determination is incorrect, the width of the movable area A at the place where the erroneous determination was made is It may be set widely. The determination as to whether the determination is an erroneous determination may be made by a manager or the like identifying a point based on the travel record and making a determination.

  Note that 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 the information (polygon data on the map) of the movable area defined by the geofence in the movable area storage unit 117 (step S14). In the movable area storage unit 117, positional information on the departure place and the destination and information on the movable area are registered in association with the ID of the movable area.

  According to the above procedure, the movement management server 10 creates a movable area when traveling from a certain departure point to a certain destination. In the movable area storage unit 117, for example, information of movable areas along each route from a generation place or accumulation place of a load to a 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 using route information and the like in the facility included in data on the facility and the like. If such route information in the facility is not prepared, it may be generated in advance and stored in the external storage device 12 or the like.

(Moveable area setting process)
The movement management server 10 sets the movable area for the truck 30 based on the position information at the time when the truck 30 starts transporting the cargo.

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

  When an operation input indicating the start of transportation is performed, the mobile terminal 31 acquires position information via the GPS receiver 32, and transmits the acquired position information and a "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 the movable area including the point indicated by is registered (step S23).

  If the corresponding 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 the linked information in the monitoring information storage unit 118. (Step S24). Furthermore, the movable area setting unit 114 transmits a “notable for setting the movable area setting” to the mobile terminal 31 (step S25).

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

  If the corresponding movable area is not registered in step S23 (NO), the standby state is set, and then the track 30 moves and the point indicated by the received position information when the position information is received again If the movable area in which is included is registered, the process proceeds to step S24.

The setting process of the movable area will be described with reference to FIGS.
FIG. 6 is a diagram for explaining an example in the case where 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 Only one movable area (E1 in the example of FIG. 6) includes the position P at the time of first detection. In such a case, the movable area setting unit 114 associates the movable area E1 with the mobile terminal 31 and registers the same in the monitoring information storage unit 118.

  FIG. 7 is a diagram for explaining an example in the case where there are a plurality of corresponding movable areas. As shown in FIG. 7, among the three movable areas (E1, E2, E3) registered in the movable area storage unit 117, it is assumed that the departure places of the routes corresponding to E1 and E2 are common, Parts of E1 and E2 overlap. In such a case, when the mobile terminal 31 departs from the position P at the time of the transportation start operation, E1 and E2 are extracted as movable areas. In this case, the movable area setting unit 114 associates the movable areas E 1 and E 2 with the mobile terminal 31 and registers them in the monitoring information storage unit 118.

  The means for acquiring outdoor position information is not limited to the GPS receiver 32 as described above, and may be acquired via a base station with which the mobile terminal 31 communicates, WiFi, or the like. Moreover, when acquiring indoor positional information, it can acquire using methods, such as BLE (Bluetooth Low Energy) positioning, geomagnetic positioning, an autonomous navigation, etc. other than the positioning using WiFi.

(Movement management process)
The movement management server 10 monitors whether the truck 30 travels in the set movable area until it arrives from the departure place to the destination.

FIG. 8 is a sequence diagram of the movement management process of the movement management 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 behavior management server 10 (step S31).

  When the movement management server 10 receives the position information from the mobile terminal 31 in the mobile object 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 be linked. It is determined whether it exists in the possible area (step S33). When a plurality of linked movable areas are registered, the determination is performed for each movable area.

  If the mobile object position monitoring unit 115 determines that the mobile terminal 31 does not exist in the movable area (step S33: NO), the mobile terminal 31 and the administrator terminal 20 indicate that the mobile terminal 31 and the administrator terminal 20 are out of the movable area. It notifies (step S34). When a plurality of linked movable areas are registered, when the mobile terminal 31 does not exist in any movable area, it is notified that the mobile terminal 31 is out of the movable area. Moreover, you may notify to the terminal which another related party hold | maintains.

  If it is determined that the mobile terminal 31 exists in the movable area (step S33: YES), it is determined whether there are a plurality of set movable areas, and if there is more than one (step S35: YES), It is checked whether there is a movable area in which the mobile terminal 31 does not exist in the area (step S36). If there is a movable area in which the mobile terminal 31 does not exist in the area (step S36: YES), the association between the corresponding movable area and the mobile terminal 31 is released (step S37). The movement management server 10 repeats the above processing until the truck 30 arrives at the destination.

  The mobile terminal 31 and the manager terminal 20 notified that the mobile terminal 31 is out of 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 linked to the mobile terminal 31, the monitoring information storage unit 118 may hold the number of linked movable areas. If it is determined by the mobile object position monitoring unit 115 that the mobile terminal 31 has moved out of one movable area, the number of movable areas linked is reduced by one, and the number of movable areas linked is zero. If 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, in the case where there are a plurality of movable areas formed along a plurality of routes, a monitoring target area in which a monitoring target such as a track first enters is a monitoring target Since it was linked with the monitoring target as the movable area to be monitored that the data exists inside, and monitoring was performed until the destination was reached, the monitoring target is appropriate when there are multiple candidates for the movable area. It is possible to automatically associate with a movable area.

  In addition, when there are a plurality of movable areas in which the monitoring target is initially included, all the applicable movable areas are linked to the monitoring target, and within any movable areas to which the monitoring target is linked. Since it is determined that the monitoring target does not exist in the movable area when it does not exist either, it is possible to cope with a case where there are a plurality of movable areas in which some areas overlap.

  In addition, when the monitoring target goes out of any of the movable areas of the originally linked multiple movable areas, the linkage with the movable area is released. Therefore, even in the case where there are a plurality of initially linked movable areas, monitoring can be performed efficiently.
