Embodiment of the invention 1.
The forgotten object detection system according to the first embodiment of the present invention will be described with reference to the drawings. The forgotten object detection system detects an forgotten object in a vehicle that turns back at the end point and travels in the opposite direction on the same route. For example, it is a vehicle that makes a round trip on a predetermined route. Here, the target vehicle is typically a train (train), but is not limited to this, and may be a bus, a ship, or an airplane.

FIG. 1 is a block diagram showing the overall configuration of the forgotten object detection system. As shown in the figure, the forgotten object detection system 1 includes a boarding detection unit 101, a moving means specifying unit 102, and a forgotten object detection unit 103.

The vehicle detection unit 101 detects that the mobile device is inside the vehicle. The transportation means specifying unit 102 estimates a vehicle having a mobile device. Based on the position information of the mobile device, the forgotten object detection unit 103 moves on the estimated vehicle route from the first direction (for example, the traveling direction of the outward route) to the direction opposite to the first direction (for example, the traveling direction of the return route). ) Detects that the mobile device has moved. The forgotten item detection unit 103 determines that the mobile device is a forgotten item by recognizing that the moving direction of the mobile device is in the opposite direction.

According to the forgotten object detection system according to the present embodiment, it is possible to detect that the mobile device is forgotten by the vehicle and remains mounted. A user who gets on a vehicle that goes back and forth in a certain section usually moves only in one direction, except when he / she has overslept. On the other hand, the vehicle usually then travels in the opposite direction, even if it arrives at the end point. Therefore, the fact that the mobile device has moved from the first direction to the opposite direction on the route of the vehicle means that the mobile device has been forgotten somewhere in the vehicle, so to speak, away from the user's hand. Most likely in a state. In the present embodiment, from such a viewpoint, it is detected that the mobile device is in a forgotten state by detecting that the mobile device has moved from the first direction to the opposite direction on the route of the vehicle. be.

Embodiment of the invention 2.
The forgotten object detection system according to the second embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 2, the forgotten object detection system 1 includes a mobile device 10 and a server 20. The mobile device 10 and the server 20 are communicably connected by a communication network 30. The communication network 30 includes a wireless communication network and an internet communication network.

The mobile device 10 includes, for example, a smartphone terminal, a mobile phone, an IoT (Internet of Things) terminal, and a wearable terminal. As wearable terminals, there are various terminals such as wristband type smart watches, eyeglass type, and clip type.

The mobile device 10 includes a boarding detection unit 11. The vehicle detection unit 11 detects that the user gets on the vehicle and the mobile device 10 is inside the vehicle. In order to realize this function, the vehicle detection unit 11 includes a GPS 111, a position information database (DB) 112 regarding the route of the vehicle, and a motion sensor 113.
The mobile device 10 executes a forgotten object detection method for detecting a forgotten object of the mobile device 10 in a vehicle. Specifically, the mobile device 10 obtains the traveling direction of the vehicle on which the mobile device 10 is estimated to be placed, based on the position information of the mobile device 10. Next, when the mobile device 10 detects that the mobile device 10 has moved from the first direction on the route of the vehicle to the direction opposite to the first direction based on the obtained traveling direction. , It is determined that the portable device 10 is a forgotten item.
The mobile device 10 executes a forgotten object detection program for detecting a forgotten object of the mobile device 10 in a vehicle. Specifically, the mobile device 10 moves from the first direction to the direction opposite to the first direction on the route of the vehicle on which the mobile device 10 is presumed to be placed, based on the position information of the mobile device 10. By detecting that the mobile device 10 has moved, the computer is made to execute a process of determining that the mobile device 10 is a forgotten item.

The GPS 111 functions as a position information acquisition unit that acquires the current position of the mobile device 10. Further, the position information DB 112 functions as a route information storage unit that stores the route position information in which the position information regarding the route of the vehicle and the identification information of the vehicle are associated with each other in a storage means such as a memory. This route position information may be acquired by downloading from the outside such as a server when necessary.

The current position information of the mobile device 10 is acquired by the GPS 111, and is stored together with the acquired time information in a storage unit such as a memory of the mobile device 10. When the mobile device 10 is in the vehicle, the position information of the mobile device 10 indicates the position of the vehicle. The vehicle that is the subject of the embodiment of the present invention reciprocates in a certain section of a predetermined route. Therefore, once the vehicle position information is known, it is possible to know on which vehicle the mobile device 10 is located by referring to the route position information stored in the above-mentioned position information DB 112. Routes are also called routes in the case of trains and buses.

The motion sensor 113 functions as an acceleration sensor that acquires acceleration information by detecting the acceleration of the portable device 10. When the portable device 10 is in a vehicle, the acceleration of the portable device 10 indicates the acceleration of the vehicle. Here, the type of vehicle can be determined if acceleration information can be obtained. For example, when a train departing from a station runs, it accelerates slowly at a lower acceleration than a general private car in consideration of passenger safety and ride quality. Therefore, the acceleration information of the mobile device 10 can be used to identify the type of vehicle on which the mobile device 10 will be mounted, and thereby it is possible to reliably determine that the mobile device 10 is in the vehicle.

Therefore, the GPS 111 can infer which route of the vehicle the vehicle is located on, and the motion sensor 113 can more accurately determine that the portable device 10 is in the vehicle. In this way, the boarding detection unit 11 detects that the user carrying the mobile device 10 gets on the vehicle and the mobile device 10 is in the vehicle.

When the vehicle detection unit 11 detects that the mobile device 10 is in the vehicle, the vehicle detection unit 11 transmits a vehicle detection notification to that effect to the server 20. The boarding detection notification includes information indicating that the boarding has been detected, route identification information for identifying the route of the boarded vehicle, position information of the mobile device 10 and its acquisition time information, and a user who identifies the mobile device 10 and the user. Contains identification information.

The transportation means specifying unit 21 specifies the vehicle on which the user has boarded in more detail. Specifically, the transportation means specifying unit 21 includes a timetable information storage unit that stores timetable information in which the position of the vehicle is determined in relation to the time. The transportation means specifying unit 21 identifies which vehicle is on the route of the vehicle specified by the GPS 111 by referring to the timetable information using the position information and the time information acquired by the GPS 111. Can be done.

That is, the transportation means specifying unit 21 departs not only from the type of vehicle but also from a specific starting point (in the case of a train, the starting station) at what time, and at what time each intermediate point (in the case of a train, an intermediate station). It is possible to determine whether the vehicle has passed and arrived at a specific end point (in the case of a train, the end station). In this way, the moving means specifying unit 21 can predict to which position the vehicle on which the mobile device 10 is placed (inside) will move at each time. In particular, the transportation means specifying unit 21 according to the present embodiment can acquire scheduled information regarding the scheduled time when the vehicle arrives at the end point and the time when the vehicle departs in the opposite direction from the end point from the timetable information.

Here, when the timetable information is temporarily changed due to an accident, failure, or the like, the transportation means specifying unit 21 acquires the changed information from the timetable management server (not shown) of the vehicle and the timetable. It is preferable to have a function of correcting information.

The forgotten object detection unit 22 detects that the mobile device 10 has moved from the first direction to the opposite direction on the estimated route of the vehicle based on the position information of the mobile device 10. It is determined that the item is not carried by the user but is forgotten. When the vehicle is a train, for example, when the mobile device 10 moves in the upward direction and then moves in the downward direction, the mobile device 10 is determined to be a forgotten item.

For example, on a line as shown in FIG. 3, it is assumed that a train departing from A station stops at B station and then arrives at C station. It can be determined from the position information of a plurality of points acquired by GPS 111 that the mobile device 10 has moved from the B station toward the C station on this outbound route. Then, it is assumed that the train turns back at C station, heads for B station, stops at B station, and then arrives at A station. On this return route, it can be determined from the position information of the plurality of points acquired by the GPS 111 that the mobile device 10 has moved from the C station toward the B station.

The position information of the mobile device 10 is acquired by the boarding detection unit 11 by the GPS 111 of the mobile device 10 and transmitted to the server 20 together with the time information. Here, the boarding detection unit 11 may continuously transmit the position information to the server 20 at predetermined time intervals, triggered by the detection that the mobile device 10 is in the vehicle.

More preferably, the boarding detection unit 11 acquires the position information of the mobile device 10 from a predetermined time (for example, 5 minutes before) the time when the vehicle specified by the transportation means specifying unit 21 is scheduled to arrive at the end point. Start and send to server 20. That is, the vehicle detection unit 11 may suppress the processing for a period from the detection that the mobile device 10 is in the vehicle to a predetermined time before the arrival time at the end point of the vehicle. Further, the boarding detection unit 11 continuously acquires the position information of the mobile device 10 and transmits it to the server 20 until a predetermined time after the estimated time of arrival at the end point (for example, 15 minutes later). Here, when the scheduled departure time for returning to the return route after returning to the end point is known from the timetable information, the boarding detection unit 11 has the position information of the portable device 10 until a predetermined time after the scheduled departure time. May be continuously acquired and transmitted to the server 20. As for the time zone in which the location information should be acquired, only the process of acquiring the location information and storing it in the storage unit may be executed, and the location information may be collectively transmitted to the server 20 after the time zone has elapsed.

In the above, the case where the boarding detection unit 11 voluntarily acquires the position information and transmits it to the server 20 is shown, but the acquisition method of the position information is not limited to this. For example, the forgotten object detection unit 22 of the server 20 transmits the request information requesting the acquisition of the location information to the mobile device 10, and the mobile device 10 acquires the location information in response to the request information to the server 20. You may send it.

The forgotten object detection unit 22 indicates that the mobile device 10 does not move for a predetermined time (for example, 30 minutes) or more at the end point of the route, and that the mobile device 10 stays in the facility (within a certain range) at the end point. When it is detected from, it may be detected as a forgotten item.

When the forgotten item detection unit 22 detects the forgotten item of the mobile device 10, the forgotten item notification unit 23 executes a process of notifying a predetermined notification destination (predetermined notification destination) to that effect. As a predetermined notification destination, for example, there is a management company that manages vehicles. More preferably, the corresponding job department is notified of the forgotten item by e-mail or the like.

The forgotten object notification unit 23 may acquire the travel schedule information of the vehicle on which the mobile device 10 is mounted from the timetable information and notify the destination at the time of processing. For example, in the case of the route shown in FIG. 3, if a lost item is found while the train is heading from C station to B station, a notification is given to B station or A station. More specifically, it is advisable to notify the mobile terminal carried by the person in charge of handling the forgotten item at B station or A station. Further, the notification may be given to the mobile terminal carried by the crew of the vehicle on which the mobile device 10 is mounted, or the terminal mounted on the vehicle itself. In this way, by notifying about the forgotten item, the crew member or the person in charge can collect the forgotten item portable device 10 more quickly.

Subsequently, with reference to FIG. 4, the flow of processing in the forgotten object detection system according to the present embodiment will be described.

As shown in FIG. 4, the forgotten object detection process is started by a predetermined trigger (S101). For example, the user may operate the mobile device 10 to execute the forgotten object detection process. Further, the boarding detection unit 11 of the mobile device 10 may automatically execute the forgotten item detection process in a time zone registered in advance by the user as a time zone in which there is a high possibility of going out. Further, based on the schedule information of the user registered in the mobile device 10, the boarding detection unit 11 of the mobile device 10 automatically executes the forgotten item detection process at the time when there is a high possibility of getting on the vehicle. May be good

The boarding detection unit 11 acquires the position information of the mobile device 10 by the GPS 111 in response to the start of the forgotten object detection process (S102). The GPS 111 stores the acquired position information in a storage means such as a memory together with the time information indicating the acquisition time. More specifically, the boarding detection unit 11 acquires the position information of the mobile device 10 at predetermined time intervals over a plurality of times.

The boarding detection unit 11 further acquires acceleration information of the portable device 10 by the motion sensor 113 (S103). The motion sensor 113 stores the acquired acceleration information in a storage means such as a memory together with the time information indicating the acquisition time. More specifically, the boarding detection unit 11 acquires the acceleration information of the portable device 10 at predetermined time intervals over a plurality of times.

Next, the boarding detection unit 11 determines whether or not the mobile device 10 is in the vehicle (S104). Specifically, the boarding detection unit 11 refers to the route position information stored in the position information DB 112 based on the current position information acquired by the GPS 111, and the mobile device 10 is on the route and is located in the vehicle. Determine if it is inferred to do.

Further, the vehicle detection unit 11 determines whether or not the mobile device 10 is in the vehicle targeted by the embodiment of the present invention, based on the acceleration information of the mobile device 10 acquired by the motion sensor 113.

When the boarding detection unit 11 detects that the current position of the mobile device 10 is on the route and the mobile device 10 is in a predetermined vehicle, it determines that the mobile device 10 is in the riding state. Proceed to the next process. On the other hand, if it is determined that the boarding detection unit 11 is not in the boarding state, the position information acquisition process or the like is executed again.

When the vehicle detection unit 11 detects that the mobile device 10 is in the vehicle, the vehicle detection unit 11 stops the position information acquisition process and the acceleration information acquisition process (S105). In this way, the processing load of the mobile device 10 can be reduced by stopping the acquisition process until the acquisition process of these pieces of information, which will be described later, is started.

Next, the boarding detection unit 11 transmits a boarding detection notification to that effect to the server 20. The boarding detection notification includes information indicating that the boarding has been detected, route identification information for identifying the route of the boarded vehicle, position information of the mobile device 10 and its acquisition time information, and a user who identifies the mobile device 10 and the user. Contains identification information.

The transportation means specifying unit 21 of the server 20 executes a process of specifying the vehicle on which the user has boarded in more detail (S106). The transportation means specifying unit 21 identifies which vehicle the vehicle is on by referring to the timetable information using the position information and the time information acquired by the GPS 111 with respect to the route of the vehicle specified by the GPS 111.

The forgotten object detection unit 22 acquires the time when the vehicle specified by the transportation means specifying unit 21 is scheduled to arrive at the end point (S107). Then, the forgotten object detection unit 22 determines whether or not the current time is in the boarding state before the predetermined time t1 of the arrival time at the end point (S108). For example, the forgotten object detection unit 22 requests the boarding detection unit 11 of the mobile device 10 to perform a boarding detection process. Then, the forgotten object detection unit 22 receives the result of the boarding detection from the boarding detection unit 11 and determines whether or not it is in the boarding state. If it is determined that the forgotten object detection unit 22 is not in the riding state, the forgotten object detection process is terminated (S113).

When the forgotten object detection unit 22 determines that the vehicle is in the riding state at that time, it further determines whether or not the vehicle is in the riding state until after a predetermined time t2 of the estimated time of arrival at the end point (S109). For example, the forgotten object detection unit 22 requests the boarding detection unit 11 of the mobile device 10 to perform a boarding detection process. Then, the forgotten object detection unit 22 receives the result of the boarding detection from the boarding detection unit 11 and determines whether or not it is in the boarding state. If it is determined that the forgotten object detection unit 22 is not in the riding state, the forgotten object detection process is terminated (S113).

When the forgotten object detection unit 22 determines that the vehicle is in the riding state at that time, it is determined whether the mobile device 10 stays at the end point position or moves in the direction opposite to the traveling direction to reach the end point position. Judgment (S110). The forgotten object detection unit 22 determines the traveling direction based on the movement history (position information) of the mobile device 10 in the time zone from before the estimated time of arrival at the end point t1 to after t2 of the estimated time of arrival at the end point. Perform such a determination. If it is determined that the forgotten object detection unit 22 has not moved in the opposite direction, the forgotten object detection process ends (S113).

If it is determined that the forgotten object detection unit 22 is in the riding state at that time, it is determined that the vehicle is staying at the end point position or is moving in the direction opposite to the traveling direction to reach the end point position. It is determined that the portable device 10 corresponds to a forgotten item (S111).

When the forgotten item detection unit 22 detects the forgotten item of the mobile device 10, the forgotten item notification unit 23 executes a process of notifying a predetermined notification destination to that effect.

As described above, in the forgotten object detection system according to the present embodiment, it is possible to detect that the mobile device is forgotten by the vehicle and remains mounted. In particular, in the present embodiment, since the processing for specifying the means of transportation and the processing for detecting the forgotten item are executed on the server, the processing load on the mobile device can be reduced.

Further, in the boarding detection, not only GPS but also a motion sensor is used, so that boarding detection can be performed more accurately. In particular, when the vehicle is a train and the road is running parallel to the railroad track, it is possible to effectively detect the boarding of the train.
