Description

[Technical field]

[0001] The present invention relates to an abandonment prevention device. [Background technology]

[0002] Patent Document 1 discloses an abandonment prevention device for preventing passengers from being abandoned on shuttle buses or route buses.

[0003] In this device to prevent passengers from being left behind, when the driver in the driver's seat performs the operation to disembark, a warning is issued to encourage the driver to check inside the vehicle. This warning continues until the driver presses the end button installed inside the vehicle. The end button is installed at the rear of the vehicle, away from the driver's seat at the front of the vehicle. If there are passengers remaining in the vehicle, the driver is made aware of their presence as he moves toward the end button. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3240654 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in order to install the anti-abandonment device in a vehicle, it is necessary to install an end button. Furthermore, since the warning can be ended by simply pressing the button, there is a possibility that the driver will forget the original purpose of checking the inside of the vehicle and focus on pressing the button. In such a case, there is a possibility that the presence of remaining passengers will be overlooked. Therefore, there is a demand for a system that can reduce the possibility of overlooking the presence of passengers with a simpler configuration. [Means for solving the problem]

[0006] One aspect of the present invention is A vehicle abandonment prevention device for preventing a passenger from being abandoned in a vehicle, comprising: A readable medium is installed at a plurality of confirmation points in the vehicle; A reading means for reading information from the read medium; The system is configured to have a control means which, when the driver performs an operation to disembark, outputs a warning requesting that the information be read by the reading means, and terminates the output of the warning when the information on the reading medium has been read at all of the multiple confirmation locations. Effect of the Invention

[0007] According to one aspect of the present invention, the possibility of overlooking the presence of a passenger can be reduced. [Brief description of the drawings]

[0009] Hereinafter, an embodiment of the present invention will be described by taking as an example a case where it is applied to a wagon-type children's bus (hereinafter, referred to as vehicle V). FIG. 1 is a diagram illustrating a schematic configuration of an abandonment prevention device 1. As shown in FIG. In the passenger compartment VC of the vehicle V, multiple seats S1 to S6 are lined up at intervals behind the driver's seat DS. The seat S6 in the last row is arranged at an interval between itself and the rear wall Wr of the vehicle V. The gap Sa between the seat S6 and the rear wall Wr is a space where luggage and the like can be placed. Behind the passenger seat PS is a boarding / alighting door G that opens to the side. Behind the boarding / alighting door G, a number of seats S7 to S10 are lined up at intervals. An aisle is provided between the number of seats S1 to S6 and the number of seats S7 to S10. In front of the boarding / alighting door G is an auxiliary seat S11.

[0010] The abandonment prevention device 1 is a device for preventing passengers from being abandoned in a vehicle V. The abandonment prevention device 1 includes a reading medium M (M1 to M11) installed at multiple confirmation points P (P1 to P11) in a vehicle V, a reading terminal 2 (reading means) having a function of reading information from the reading medium M (M1 to M11), and a control device 3 (control means).

[0011] The check points P1 to P10 are set in a one-to-one correspondence with the seats S1 to S10. The check points P1 to P10 are set on the walls Ws on the sides of the respective seats S1 to S10. It is preferable that the confirmation points P1 to P10 are places that satisfy the following conditions. (a) When an occupant of the vehicle V moves to the side of each of the seats S1 to S10 on the aisle side, the occupant can be seen. (b) When an occupant of vehicle V moves to the side of each of seats S1 to S10 on the aisle side and directs his or her gaze toward the inspection spot, the floor surface between adjacent seats is also visible.

[0012] The check point P11 is set on the wall (the side wall Ws or the wall Wr) facing the gap Sa between the rearmost seat S6 and the wall Wr. This is to enable the presence of passengers or items left behind to be recognized even if they are present in a gap Sa that is not related to a seat S. The check points P are not limited to the above-mentioned embodiment. The check points P may be any position that allows thorough checking of the vehicle cabin VC. The check points P may be increased or decreased, and their positions may be changed, as necessary. For example, by setting the check points P in gaps where passengers are not expected to be present, it is possible to suitably prevent unexpected abandonment.

[0013] The read medium M (M1 to M11) is a sticker on which an identification code such as a QR code (registered trademark), a barcode, etc. is printed. The read medium M (M1 to M11) is attached to a plurality of check points P1 to P11 in the vehicle interior VC. By making the read medium M (M1 to M11) a sticker on which an identification code is printed, the read medium M (M1 to M11) can be placed at a desired position in the vehicle interior VC. Therefore, it is easy to increase or decrease the number of check points P or change their positions. The places where the read medium M (M1 to M11) is attached are not limited to the walls Ws and Wr of the vehicle V. It may be attached to any visible place such as the seat S, the floor, or the ceiling. Here, the term "check point P" in this specification means a specific location in the vehicle cabin VC that needs to be checked to prevent passengers from being left behind. In the following description, among the check points P, a location where a reading medium M (M1 to M11) is attached will also be referred to as a reading point. Note that even if there is a check point P in the vehicle cabin VC, a location where a reading medium M (M1 to M11) is not installed will not be a reading point.

[0014] The reading terminal 2 (reading means) is a portable terminal having a function of reading information (identification code information) of the reading medium M (M1 to M11). It is preferable that the reading terminal 2 is of a size and weight that allows an occupant to carry the reading terminal 2 in his / her hand and move around the vehicle interior VC.

[0015] FIG. 2 is a perspective view illustrating a state in which the reading terminal 2 is set in the power supply holder 4. As shown in FIG. FIG. 3 is a diagram illustrating an example of the configuration of the control device 3 and the power supply holder 4. As shown in FIG. As shown in Fig. 2 and Fig. 3, in this embodiment, a rod-shaped member with a reader 24 attached to its tip is used as the reading terminal 2. The reader 24 has a function of reading identification code information. Here, the identification code information is, for example, the identification number of the seat associated with the reading medium M (M1 to M11). For example, the identification code information is information that can identify the position of the seat in the vehicle cabin VC, such as the third seat from the front in the right row.

[0016] In the reading terminal 2, the large diameter portion 201 of the rod-shaped base portion 20 serves as a gripping portion that is gripped by a passenger. The reader 24 is housed at the tip side of the small diameter portion 202. Inside the reading terminal 2, a processing unit 21, a storage unit 22, a communication interface (communication IF 23), a reader 24, and an input / output port (I / O) 25 are connected via a bus 200.

[0017] The processing unit 21 is a processor such as a CPU or an MPU, and based on a program stored in the storage unit 22, executes processing defined by the program. The storage unit 22 is a recording medium, such as an SSD or memory, that is capable of retaining and rewriting information. The storage unit 22 stores programs for each process performed by the processing unit 21. Furthermore, the storage unit 22 stores information generated during the process, acquisition history of read data from the read medium M (M1 to M11), and logs (event logs, communication logs) such as communication records with the control device and external servers. When storing the logs, they may be timestamped and stored in the storage unit 22.

[0018] The communication IF 23 is a communication unit that exchanges information with external devices. The communication IF 23 can be connected to a communication IF 33 on the control device 3 side. Furthermore, the communication IF 23 can be connected to an external server via the network NT.

[0019] The reader 24 is, for example, a camera. The reading terminal 2 acquires information on the medium M (M1 to M11) placed at the check point P (P1 to P11) by image processing of the medium M (M1 to M11) photographed by the reader 24. The reader 24 may be a reader for short-distance wireless communication.

[0020] An audio output unit 28 and a monitor 29 are connected to the input / output port 25 . The audio output unit 28 is, for example, a speaker. The audio output unit 28 outputs a voice message, a notification sound, an alarm sound, and the like, which prompt the user to start a checking operation, which will be described later. The monitor 29 displays text information, and the like, which prompts the user to start a checking operation, which will be described later.

[0021] A terminal 26 is provided inside the small diameter portion 202 to connect to a power supply terminal 41 of the power supply holder 4. The power supply terminal 41 is connected to an input / output port 35 on the control device 3 side via a wire 42. The power supply terminal 41 supplies power supplied from the control device 3 side to the battery 27 via the terminal 26 to charge the battery 27. The battery 27 supplies power for driving the reading terminal 2.

[0022] The housing 40 of the power supply holder 4 is fixed inside the vehicle interior VC. The housing 40 has an insertion hole 401 for the reading terminal 2. The insertion hole 401 has an inner diameter that allows the small diameter portion 202 of the reading terminal 2 to be inserted therethrough. The reading terminal 2 is held in the housing 40 with the large diameter portion 201 placed on the periphery of the insertion hole 401.

[0023] The control device 3 includes a processing unit 31, a storage unit 32, a communication interface (communication IF 33), an audio output unit 34, and an input / output port (I / O) 35. The processing unit 31, the storage unit 32, the communication IF 33, the audio output unit 34, and the input / output port 35 are connected to each other via a bus 300.

[0024] The processing unit 31 is a processor such as a CPU or an MPU, and executes processing defined by a program based on a program stored in the storage unit 32. The storage unit 32 is a recording medium capable of retaining and rewriting information, such as an HDD, an SSD, or a memory. The storage unit 32 stores programs for each process performed by the processing unit 31. Furthermore, the storage unit 32 stores information generated during the process and logs such as the acquisition history of the read data of the read medium M (M1 to M11).

[0025] The communication IF 33 is a communication unit that exchanges information with an external device. The communication IF 33 can be connected to the communication IF 23 of the reading terminal 2. Furthermore, the communication IF 33 can be connected to an external server via the network NT.

[0026] To the input / output port 35, a wire 42 extending from a power supply terminal 41, an input / output device 36, and a power supply unit 37 are connected. When the wiring 42 is connected to the input / output port 35, power is supplied to the battery 27 on the side of the reading terminal 2. The input / output device 36 is an interface for inputting instructions to the control device 3. As the input / output device 36, a terminal carried by a passenger can be used.

[0027] The power supply unit 37 is connected to an on-board power supply 71 provided in the vehicle-side system 7. One example of the on-board power supply 71 is a battery mounted on the vehicle. Driving power is supplied to the power supply unit 37 for a predetermined time even after the vehicle-side system 7 is stopped. Here, the predetermined time is determined based on the time required to read the reading medium M (M1 to M11) using the reading terminal 2. This predetermined time is set to a length that allows the reading of all the reading media M (M1 to M11) to be completed with plenty of time to spare. The monitoring unit 72 of the vehicle-side system 7 monitors whether the vehicle-side system 7 is on or off, and detects whether an operation for disembarking from the vehicle is performed. When the monitoring unit 72 detects an operation for disembarking, the monitoring unit 72 outputs a signal instructing the start of a confirmation operation (a confirmation operation start instruction) to the control device 3.

[0028] An example of how the abandonment prevention device 1 is used will be described below. FIG. 4 is a flowchart illustrating an example of processing in the control device 3. In the anti-abandonment device 1, when the reading terminal 2 is not in use and is in standby mode, the small diameter portion 202 of the reading terminal 2 is inserted into the insertion hole 401 of the power supply holder 4, and the reading terminal 2 is electrically connected to the control device 3.

[0029] In the vehicle-side system 7, the monitoring unit 72 constantly monitors whether or not an operation for disembarking is performed. When the monitoring unit 72 detects an operation for disembarking, the monitoring unit 72 outputs a signal instructing the start of a confirmation operation (a confirmation operation start instruction) to the control device 3.

[0030] Here, the following are examples of "operations for disembarking". (a) An operation to shut down a vehicle's system, such as when the power switch is turned off or the ignition switch is turned off, constitutes an "operation to disembark." In addition, it may be determined that an "operation to disembark" has occurred when, for example, (b) the door lock mechanism of the driver's door changes from a locked state to an unlocked state, (c) the driver's door is opened and then closed, or (d) the vehicle's smart key is taken out of the vehicle.

[0031] In the control device 3, when an instruction to start the confirmation work is input (step S101, Yes), the processing unit 31 starts a timer (step S102).

[0032] Following the start of the timer (step S102), the processing unit 31 issues a warning to prompt the occupant to perform the checking operation (step S103). For example, (a) a notification sound is output from the speaker of the input / output device 36 or the audio output unit 28 of the reading terminal 2 to prompt the user to start the confirmation work. (b) a voice message such as "Please perform the confirmation work" is output from the speaker of the input / output device 36 or the audio output unit 28 of the reading terminal 2. (c) A text message such as "Please perform the confirmation work" is output on the display of the input / output device 36 or the monitor 29 of the reading terminal 2 to call attention to the confirmation work. The attention continues continuously or intermittently until the confirmation work is completed.

[0033] As a result, the occupant who has been alerted to the confirmation operation picks up the reading terminal 2 held by the power supply holder 4 and goes to the operation of reading the read medium M (M1 to M11) in the vehicle interior VC.

[0034] Next, the processing unit 31 checks whether a predetermined time has elapsed since the timer started (step S104). This is because a time limit is set for the completion of the confirmation work to prevent the occupant from leaving the vehicle V without noticing the warning or from leaving the vehicle V without performing the confirmation work.

[0035] If the predetermined time has not elapsed (step S104, No), the processing unit 31 checks whether or not read data of the medium to be read M (M1 to M11) has been input (step S105). Here, input of read data means, for example, a case where information indicating a read result transmitted from the reading terminal 2 side is received.

[0036] If no read data has been input (No in step S105), the process returns to step S104, whereby the presence or absence of input of read data is confirmed until a predetermined time has elapsed. Here, if the predetermined time has elapsed without any input of read data (Yes in step S104), the process proceeds to step S108, where the processing unit 31 executes a warning process.

[0037] As an example, in the warning process, (a) an alarm sound indicating that no read data has been input is output from the speaker of the input / output device 36 or the audio output unit 28 of the reading terminal 2. (b) a voice message such as "No read data has been input" is output from the speaker of the input / output device 36 or the audio output unit 28 of the reading terminal 2. (c) a text message such as "No read data has been input" is output on the display of the input / output device 36 or the monitor 29 of the reading terminal 2. Then, (d) a connection is made to a predetermined external server via the communication IF 33 to notify that "no read data has been input". As a result, for example, the external server outputs a notification that "no read data has been input" to the person responsible for managing the vehicle V or a pre-specified contact person.

[0038] If the read data has been input (Yes at step S105), the processing unit 31 checks whether the read data of all the read media M (M1 to M11) has been input (step S106). Specifically, when the read data of all the reading media M (M1 to M11) has been input (Yes in step S106), it is determined that reading of all the reading media M (M1 to M11) has been completed.

[0039] If the input of the read data of all the read media M is not confirmed (step S106, No), the process returns to step S104. This allows the process to confirm whether or not the read data of all the read media M has been input until a predetermined time has elapsed. Here, if the predetermined time has elapsed without inputting the read data of all the read media M (Yes in step S104), the process proceeds to step S108, where the processing unit 31 executes a warning process.

[0040] As an example, in the warning process in this case, (a) an alarm sound is output from the speaker of the input / output device 36 or the audio output unit 28 of the reading terminal 2 to the effect that the checking of all the check points (reading of the read points) has not been completed. (b) an audio message such as "Checking of all the check points (reading of the read points) has not been completed" is output from the speaker of the input / output device 36 or the audio output unit 28 of the reading terminal 2. (c) a text message such as "Checking of all the check points (reading of the read points) has not been completed" is output on the display of the input / output device 36 or the monitor 29 of the reading terminal 2. Then, (d) a connection is made to a predetermined external server via the communication IF 35 to notify that "checking of all the check points (reading of the read points) has not been completed." As a result, for example, the external server will output a notification to the person responsible for managing the vehicle V or a pre-designated contact person stating that "not all check points have been checked (reading of read points)." It is preferable that the notification sound prompting the start of the confirmation work (reading of the reading location), the alarm sound indicating that the confirmation work (reading of the reading location) has not been performed, and the alarm sound indicating that the confirmation work has not been completed (reading of the reading location has not been completed) are different sounds.

[0041] When it is confirmed that the read data of all the read media M (M1 to M11) has been input (Yes in step S106), the processing unit 31 performs an end process (step S107).

[0042] Specifically, in the termination process, the warning started in the process of step S103 is terminated. In addition, for example, (a) a sound notifying the completion of the confirmation work is output from a speaker included in the input / output device 36 or the audio output unit 28 of the reading terminal 2; (b) a voice message such as "The confirmation work is completed" is output from a speaker included in the input / output device 36 or the audio output unit 28 of the reading terminal 2; (c) a text message such as "The confirmation work is completed" is output on a display included in the input / output device 36 or the monitor 29 of the reading terminal 2; and (d) a connection is made to a predetermined external server via the communication IF 33 to notify the completion of the confirmation work.

[0043] Next, the processing unit 31 stores the log in the storage unit 32 (step S109). For example, when the process of step S109 is performed after the end process (step S107), the acquisition history of the read data of all the read media M (M1 to M11) and logs (event logs, communication logs) such as communication records with external servers are stored in the storage unit 32. When storing the logs, a timestamp may be added and the logs may be stored in the storage unit 32. For example, when the process of step S109 is performed after the warning process (step S108), an error log is stored in the storage unit 32 indicating the reason why the warning process was performed.

[0044] As described above, the confirmation points P1 to P10 are set in a one-to-one correspondence with the seats S1 to S10 (see FIG. 1) and are provided at positions that are visible to the occupants of the vehicle V when they move to the aisle side of each seat S1 to S10. When the occupant of the vehicle V moves to the side of the aisle of each of the seats S1 to S10 and directs his or her gaze toward the checking spot, the floor surface between the adjacent seats is also visible. Furthermore, the confirmation point P11 is set on the wall (the side wall Ws or the wall Wr) surrounding the gap Sa between the rearmost seat S6 and the wall Wr. Even if a passenger or baggage is present in the gap Sa that is not related to the seat S, the presence of the passenger or baggage can be recognized.

[0045] This allows passengers remaining in the vehicle to be found reliably during the confirmation process. In particular, since a rod-shaped member with an identification code reader 24 attached to the tip is used as the reading terminal 2, the line of sight can be guided by pointing the reading terminal 2 at the reading medium M (M1 to M11) at each confirmation point P (P1 to P11). This allows for reliable visual confirmation, and more reliably reduces the possibility of missing passengers left behind.

[0046] As described above, the abandonment prevention device 1 according to the present embodiment has the following configuration. (1) The abandonment prevention device 1 is a device for preventing passengers from being abandoned in a vehicle V. The vehicle abandonment prevention device 1 includes a plurality of readable media M (M1 to M11) installed at a plurality of check points P (P1 to P11) in a vehicle V, A reading terminal 2 (reading means) that reads information from a reading medium M (M1 to M11); and a control device 3 (control means). The control device 3 has a processing unit 31 that outputs a warning requesting that the reading medium M (M1 to M11) be read by the reading terminal 2 when the driver performs an operation to disembark, and terminates the output of the warning when the reading medium M (M1 to M11) has been read at all of the multiple confirmation points P (P1 to P11).

[0047] With this configuration, reading media are installed at multiple check points in the vehicle V, and the output of the warning cannot be terminated until reading is completed at all check points P (P1 to P11). Compared to a specification in which the warning can be terminated by operating only one end button, the possibility of overlooking the presence of a passenger can be reduced, and passengers can be prevented from being left behind.

[0048] (2) The checking points P (P1 to P11) are provided in a one-to-one correspondence with the seats S (S1 to S10) in the vehicle V that are to be checked.

[0049] With this configuration, when the information on the reading medium M (M1 to M11) is read at all of the confirmation points P (P1 to P11), attention is directed to all of the seats S (S1 to S10), thereby reducing the possibility of overlooking the presence of remaining passengers.

[0050] (3) The check points P (P1 to P11) are also set in the gap Sa between the seat S6 and the wall Wr on the vehicle body side.

[0051] With this configuration, attention can be directed not only to the seats S (S1 to S10) but also to the gap Sa between the seat S6 and the car body wall Wr, reducing the possibility of overlooking passengers or baggage remaining outside of the normally expected locations.

[0052] (4) The reading terminal 2 (reading means) is a portable terminal having a function of reading information from the reading medium M (M1 to M11).

[0053] As described above, the reading terminal 2 is a rod-shaped member having a reader 24 that has the function of reading information from the reading medium M (M1 to M11). By using a rod-shaped reading terminal 2, the reading terminal 2 is directed toward the reading medium M (M1 to M11) at each checking point P (P1 to P11) during the checking work, and the line of sight of the person doing the checking work can be guided. This reduces the possibility of the checking work being performed absent-mindedly, and more reliably reduces the presence of passengers left behind. In addition, because the reading terminal 2 is a portable terminal, it reduces the possibility that the weight of the reading terminal 2 will be an obstacle to the checking work. Furthermore, the reading medium M (M1 to M11) is placed in a position that will be hidden by a person or baggage when a person is seated in a seat S (S1 to S10) or when baggage is placed on a seat S (S1 to S10). If a person or baggage is present, the reading of the reading medium M (M1 to M11) cannot be completed, so it is possible to reliably detect people or baggage remaining in the vehicle. This makes it possible to appropriately prevent people or baggage from being left behind on shuttle buses or route buses.

[0054] (5) The read medium M (M1 to M11) is a sticker on which information is printed.

[0055] With this configuration, the confirmation point can be set at a desired location inside the vehicle. Unlike the end button, no dedicated wiring is required, and the readable medium can be installed simply by attaching a sticker. Therefore, compared to a specification in which the warning can be ended by operating an end button, it is possible to increase the number of points to be checked at low cost and easily. Furthermore, the read medium M (M1 to M11) does not include a mechanical mechanism such as an end button, wiring, etc. Therefore, there is no need to worry about failures due to mechanical failures or broken wiring, as occurs with mechanical mechanisms and wiring.

[0056] [Variation 1] FIG. 5 is a diagram illustrating the surroundings of a portable terminal 5 (reading terminal) of an abandonment prevention device 1A according to the first modification. FIG. 6 is a diagram illustrating an abandonment prevention device 1A according to the first modification. Fig. 5 shows a state in which the portable terminal 5 (reading terminal) is set in the power supply holder 4A. Fig. 6 shows an example of the configuration of the control device 3, the power supply holder 4A, the portable terminal 5, and the vehicle-side system 7. In the above embodiment, a rod-shaped member having a reader 24 attached to the tip thereof is used as the reading terminal 2 as the reading means. In the modified example, a mobile terminal 5 equipped with a camera 54 is employed as the reading means.

[0057] In the following description, differences from the above-described embodiment will be mainly described, and common parts will be described as necessary.

[0058] As shown in FIGS. 5 and 6, the abandoned person prevention device 1A employs a portable terminal 5 equipped with a camera 54 as a reading means for reading information from a read medium M (M1 to M11). The mobile terminal 5 includes a processing unit 51, a storage unit 52, a communication interface (communication IF 53), a camera 54, an input / output port (I / O) 55, and an input / output unit 56, which are connected to one another via a bus 500.

[0059] The portable terminal 5 includes a battery 57. The battery 57 is charged with power supplied via the power supply terminal 41 of the power supply holder 4A.

[0060] The processing unit 51 is a processor such as a CPU or an MPU, and based on a program stored in the storage unit 52, executes processing defined by the program. The storage unit 52 is a recording medium, such as an SSD or memory, that is capable of retaining and rewriting information. The storage unit 52 stores programs for each process performed by the processing unit 51. Furthermore, the storage unit 52 stores information generated during the process, acquisition history of read data from the read medium M (M1 to M11), and logs (event logs, communication logs) such as communication records with external servers. When storing the logs, they may be timestamped and stored in the storage unit 52. In this modified example, data (reading location data) indicating which of the confirmation locations P (P1 to P11) in the vehicle interior VC the reading medium M (M1 to M11) is placed at is stored in advance in the memory unit 52. Here, the reading location data is prepared in advance by a user or the like and stored in the storage unit 32 of the control device 3. In the abandonment prevention device 1A, when communication is established between the control device 3 and the portable terminal 5, the reading location data stored in the storage unit 32 of the control device 3 and the reading location data stored in the storage unit 52 of the portable terminal 5 are synchronized.

[0061] The communication IF 53 is a communication unit that exchanges information with an external device. The communication IF 53 can be connected to the communication IF 33 on the control device 3 side. Furthermore, the communication IF 53 can be connected to an external server via the network NT.

[0062] The camera 54 is a conventionally known camera used in a portable terminal. The portable terminal 5 acquires information about the medium M (M1 to M11) placed at the check point P (P1 to P11) by processing the image of the medium M (M1 to M11) photographed by the camera 54. The input / output unit 56 is, for example, an interface for inputting instructions and displaying information, and is exemplified by a so-called touch display. The configurations of the control device 3 and the vehicle-side system 7 are the same as those in the above-described embodiment, and therefore a description thereof will be omitted.

[0063] An example of how to use the abandonment prevention device 1A will be described below. Fig. 7 is a flowchart explaining an example of processing in the control device 3 according to Modification 1. Fig. 8 is a flowchart explaining an example of processing in the mobile terminal 5 according to Modification 1. Fig. 9 is a diagram explaining an example of an interface screen displayed on the input / output unit 56 of the mobile terminal 5 according to Modification 1. Fig. 9 shows an example of a screen displayed when reading information from a reading medium M (M1 to M11).

[0064] In the abandonment prevention device 1A, when the portable terminal 5 is on standby and not in use, the portable terminal 5 is attached to the power supply holder 4A, and the portable terminal 5 is electrically connected to the control device 3. Note that when the communication IF 33 on the control device 3 side and the communication IF 53 of the portable terminal 5 are in a communicable state, the portable terminal 5 does not need to be electrically connected to the power supply holder 4A.

[0065] Here, the processing in step S201 and steps S203 to S210 in FIG. 7 is the same as the processing in step S101 and steps S102 to S109 in FIG. 4 described above, and therefore detailed description thereof will be omitted. In the vehicle-side system 7, the monitoring unit 72 constantly monitors whether or not an operation for disembarking has been performed. When the monitoring unit 72 detects an operation for disembarking, it outputs a signal instructing the start of a confirmation work (a confirmation work start instruction) to the control device 3. When a confirmation work start instruction is input while the communication IF 33 of the control device 3 and the communication IF 53 of the mobile terminal 5 are in a communicable state, the control device 3 transmits the input confirmation work start instruction to the mobile terminal 5.

[0066] 4 in that when an instruction to start the confirmation work is input from the vehicle-side system 7 (step S201, Yes), the control device 3 transmits an instruction to start the confirmation work to the mobile terminal 5 (step S202).

[0067] As shown in FIG. 8, when the mobile terminal 5 receives an instruction to start the confirmation work (step S301, Yes), the processing unit 51 reads out the confirmation location data stored in the memory unit 52 and displays a screen (see FIG. 9) for reading the reading medium M (M1 to M11) on the touch display of the input / output unit 56 (step S302). As shown in FIG. 9, the following is displayed, for example, on the touch display of the input / output unit 56 to prompt the user to perform the reading operation. (a) A marker MK indicating at what position on the touch display the reading medium M (M1 to M11) needs to be placed in order to read information on the reading medium M (M1 to M11). (b) Text TX1 explaining the procedure for reading (c) "Read button" icon IC1 that instructs to execute reading (d) Icon IC2 showing the reading locations in vehicle V superimposed on the seat layout in vehicle V (e) Text TX2 explaining the reading location in icon IC2

[0068] As a result, the passenger carrying the portable terminal 5 moves to the reading location displayed within the icon IC2 and executes reading of the read medium M placed at the reading location. When the information on the read medium M is read (step S303), the processing unit 51 transmits the information obtained by reading (read information) to the control device 3 (step S304). Then, the processing unit 51 changes the display mode of the portion that has been completely read out of the read portions displayed on the icon IC2 (step S305).

[0069] Next, the processing unit 51 checks whether or not reading of all the reading locations has been completed (step S306). If reading of all the reading locations has not been completed (No in step S306), the process returns to step S302. As a result, the processes in steps S302 to S306 are repeated until reading of all the reading locations has been completed. When reading of all the reading points is completed (step S306, Yes), the control device 3 is notified of the completion of reading (step S307). As a result, the control device 3 executes the end process (step S208, see FIG. 7) using the reception of the reading completion notification as a trigger. At this time, a message indicating that reading has been completed may be displayed on the touch display.

[0070] This configuration also makes it possible to reliably find passengers remaining in the vehicle V during the confirmation work. In particular, since the portable terminal 5 equipped with the camera 54 is used, the gaze can be guided by directing the portable terminal 5 toward the reading medium M (M1 to M11) at each confirmation point P (P1 to P11). This allows for reliable visual confirmation, and more reliably reduces the possibility of missing passengers who are left behind. Also, since the read location is displayed on the touch display of the mobile terminal 5, and the read-completed and incompleted locations are displayed in an easily identifiable manner, it is possible to prevent overlooking of a read location. Furthermore, since it is possible to eliminate the effort of searching for the read location, it is expected that the efficiency of the confirmation work will improve.

[0071] As described above, the abandonment prevention device 1A according to the first modification has the following configuration. (1) The abandonment prevention device 1A is a device for preventing passengers from being abandoned in a vehicle V. The vehicle abandonment prevention device 1A includes a plurality of readable media M (M1 to M11) installed at a plurality of check points P (P1 to P11) in a vehicle V, A portable terminal 5 (reading means) that reads information from a read medium M (M1 to M11); and a control device 3 (control means). The control device 3 has a processing unit 31 that outputs a warning requesting the portable terminal 5 to read the reading medium M (M1 to M11) when the driver performs an operation to disembark, and terminates the output of the warning when the information on the reading medium M (M1 to M11) has been read at all of the multiple confirmation locations P (P1 to P11).

[0072] With this configuration, reading media M (M1 to M11) are installed at multiple check points in the vehicle V, and the output of the warning cannot be ended until reading is completed at all check points P (P1 to P11). Compared to a specification in which the warning can be ended by operating only one end button, the possibility of overlooking the presence of a passenger can be reduced and passengers can be prevented from being left behind.

[0073] Here, the matters shown in (2) to (5) in the above embodiment are also subordinate to the description in (1) regarding the abandonment prevention device 1A.

[0074] (I) In the portable terminal 5, the processing unit 51 displays an assistance screen for reading the medium to be read M (M1 to M11) on the touch display of the input / output unit 56 (see FIG. 9). On the touch display, confirmation points P (P1 to P11) in the vehicle compartment VC are displayed superimposed on the seat layout in the vehicle V. The display mode of a check point P where information reading has been completed is different from the display mode of a check point P where information reading has not been completed.

[0075] With this configuration, the read location is displayed on the touch display of the mobile terminal 5, and the read-completed and incompleted locations are displayed in a distinguishable manner. This makes it possible to prevent reading omissions at the read location. Furthermore, since the effort of searching for the read location can be eliminated, the efficiency of the confirmation work can be expected to improve.

[0076] [Variation 2] FIG. 10 is a flowchart illustrating an example of processing in the mobile terminal 5 in the second modification. In the above-described modified example 1, the read information acquired by the portable terminal 5 is processed on the control device 3 side. In the modified example 2, the read information acquired by the portable terminal 5 is processed on the portable terminal 5 side.

[0077] When the monitoring unit 72 of the vehicle-side system 7 detects an operation for disembarking, a signal instructing the start of a confirmation work (a confirmation work start instruction) is input to the control device 3. When the confirmation work start instruction is input while the communication IF 33 of the control device 3 and the communication IF 53 of the mobile terminal 5 are in a communicable state, the control device 3 outputs the input confirmation work start instruction to the mobile terminal 5.

[0078] When the mobile terminal 5 receives an instruction to start the confirmation work (step S401, Yes), After the processing unit 51 starts a timer (step S402), the processing unit 51 issues a warning to prompt the occupant to perform a checking operation (step S403). Next, the processing unit 51 reads out the check location data stored in the memory unit 52, and displays a screen (see FIG. 9) for reading the reading medium M (M1 to M11) on the touch display of the input / output unit 56 (step S404).

[0079] As a result, the passenger carrying the portable terminal 5 moves to the check location displayed within the icon IC2 (see FIG. 9) and executes reading of the read medium M placed at the check location. Here, if the predetermined time has elapsed without the reading being completed (Yes in step S405), the process proceeds to step S410, where the processing unit 31 executes a warning process. If reading of information on the reading medium M is performed (step S406, Yes) before a predetermined time has elapsed (step S405, No), the processing unit 51 changes the display mode of the reading portion displayed on the icon IC2 that has been completed for reading (step S407).

[0080] Next, the processing unit 51 checks whether or not reading of all the reading locations has been completed (step S408). If reading of all the reading positions has not been completed (step S408, No), the process returns to step S405, whereby the processes of steps S405 to S408 are repeated until reading of all the reading positions has been completed. When reading of all the reading locations is completed (step S408, Yes), the processing unit 51 performs a termination process (step S409), and the control device 3 and the external server are notified of the completion of reading. Next, the processing unit 51 stores the log in the storage unit 52 (step S411), and then ends the process. The specific contents of the processes in steps S409, S410, and S411 are substantially the same as those in steps S107, S108, and S109 (see FIG. 4), and therefore detailed description thereof will be omitted here.

[0081] [Variation 3] Fig. 11 is a diagram illustrating an abandoned prevention device according to Modification 3. Fig. 11 shows a case where an IC tag, typically an NFC tag, is used as the reading medium M (M1 to M11), and a wearable terminal 6 is used as the reading terminal. The control device 3 of the abandoned prevention device 1B has the same configuration as the control device 3 shown in Fig. 6. In the above embodiment, the read medium M (M1 to M11) is a sticker on which an identification code is printed. Instead of a printed identification code, an IC tag may be used. In this case, an identification code such as an identification number is registered in the IC tag T (T1 to T11) for use. Here, an IC tag is an item with an IC chip and antenna embedded in a protective material such as a sticker or card. By registering the identification number of the checkpoint on the IC tag, the information registered on the IC tag can be read by bringing an NFC reading terminal close to the IC tag.

[0082] In the third modification, a wearable terminal 6 carried by a passenger is used as the reading terminal. Reading of information by the wearable terminal 6 is performed by a reader 64 of the wearable terminal 6 communicating with an IC tag using near field communication (NFC) technology. The functions of the processing unit 61 and the storage unit 62 of the wearable terminal 6 are basically the same as those of the corresponding processing unit 51 and storage unit 52 of the mobile terminal 5 shown in Fig. 6. The input / output unit 69 is an interface for inputting instructions and displaying information, similar to the input / output unit 56 described above, and an example of the input / output unit 69 is a so-called touch display. The reader 64 is a wireless communication device for reading information from an IC tag. The communication IF 63 is a communication device for communicating with the control device 3 and an external server.

[0083] FIG. 12 is a flowchart illustrating an example of processing in the wearable terminal 6 according to the third modification. As shown in FIG. 12, when the wearable terminal 6 receives an instruction to confirm the confirmation location (step S501, Yes), the processing unit 61 displays text information requesting reading of the reading medium M (M1 to M11) on the touch display of the input / output unit 69, and outputs a voice message requesting reading of the reading medium M (M1 to M11).

[0084] As a result, the passenger carrying the wearable terminal 6 moves to the reading location and executes reading of the read medium M placed at the reading location. Specifically, the occupant brings the wearable device 6 close to the IC tags T (T1 to T11) placed at the check points P (P1 to P11) to acquire information about the IC tags T (T1 to T11).

[0085] When the information on the read medium M (M1 to M11) is read (Yes in step S502), the processing unit 61 transmits the information obtained by reading (read information) to the control device 3 (step S503). Then, the processing unit 61 checks whether or not reading of all the reading locations has been completed (step S504). If reading of all the reading positions has not been completed (step S504, No), the process returns to step 502. As a result, the processes of steps S502 to S504 are repeated until reading of all the reading positions has been completed. When reading of all the reading locations is completed (Yes in step S504), the control device 3 is notified of the completion of reading (step S505). At this time, a message indicating completion of reading may be displayed on the touch display. The processes in steps S402 to S405 performed by the control device 3 may be completed by the wearable terminal 6.

[0086] In addition, when the inspection work at the inspection points P (P1 to P11) is performed, the disinfection and cleaning work of the seats may be performed in parallel. When a passenger holds a cloth sprayed with disinfectant in his / her hand and wipes the seat, the IC tag T (T1 to T11) is installed near the seat, and the information of the IC tag T (T1 to T11) can be obtained during the wiping operation.

[0087] In this case, the checking work can be done unconsciously while performing the usual cleaning work, which is expected to reduce the psychological burden on the crew of having to perform the checking work.

[0088] As described above, the abandoned vehicle prevention device 1B according to this modified example has the following configuration: (1) The vehicle abandonment prevention device 1B includes IC tags T (T1 to T11) that are readable media and are installed at a plurality of confirmation points P (P1 to P11) in a vehicle V, A wearable terminal 6 (reading means) that reads information from IC tags T (T1 to T11); and a control device 3 (control means). The control device 3 has a processing unit 31 that outputs a warning requesting that the IC tag T (T1 to T11) be read by the wearable terminal 6 when the driver performs an operation to disembark, and terminates the output of the warning when the information on the IC tag T (T1 to T11) has been read at all of the multiple confirmation points P (P1 to P11).

[0089] With this configuration, IC tags T (T1 to T11) are installed at multiple check points on the vehicle V, and the output of the warning cannot be terminated until reading is completed at all check points P (P1 to P11). Compared to a specification in which the warning can be terminated by operating only one end button, the possibility of overlooking the presence of a passenger can be reduced, and passengers can be prevented from being left behind.

[0090] Here, the matters shown in (2) to (4) in the above embodiment are also subordinate to the description in (1) regarding the abandonment prevention device 1B.

[0091] (6) The reading medium is an IC tag T (T1 to T11). The IC tag T (T1 to T11) is a tag for contactless communication that has information unique to the reading medium.

[0092] For example, if an IC tag that performs wireless communication using induced current is used as the reading medium, there is no need to install wiring to supply power to the reading medium at each confirmation point.The reading medium can be installed without requiring dedicated wiring like an end button. Therefore, compared to a specification in which the warning can be ended by operating an end button, it is possible to increase the number of points to be checked at low cost and easily.

[0093] In the above embodiment, the read medium M (M1 to M11) is a sticker on which information is printed, and the sticker is attached to a desired location inside the vehicle. The read medium M (M1 to M11) may be installed at a desired location in the vehicle by the following method. (a) Information is printed on an information printing medium such as paper, cloth, or film, and the information printing medium on which the information is printed is fixed to a desired location inside the vehicle by any method. (b) printing the information on a seat cover and placing the seat cover with the printed information on it over the seat; (c) Printing the information directly on the seats. (d) Information is directly inscribed on walls Ws, handrails, floors, etc. at desired locations inside the vehicle without using a printing medium.

[0094] In the above embodiment, the reading means is the reading terminal 2 and the portable terminal 5 when the reading medium M (M1 to M11) is a sticker on which information is printed. The reading means is the wearable terminal 6 when the reading medium M (M1 to M11) is an IC tag T (T1 to T11). The reading terminal 2 and the portable terminal 5 may be used as the reading means when the reading medium M (M1 to M11) is an IC tag T (T1 to T11). In addition, the spray bottle used when cleaning the seats can be equipped with a camera or a reading terminal that uses near-field communication (NFC) technology, allowing checking work to be done in parallel with the cleaning work.

[0095] Although the embodiment of the present invention has been described above, the above embodiment merely shows one application example of the present invention, and the technical scope of the present invention is not limited to the specific configuration of the above embodiment. Appropriate modifications are possible within the scope of the technical concept of the invention. [Explanation of symbols]
