[Embodiment 1]
The lost property detection system according to the embodiment 1 will be described with reference to the drawings. Fig. 1 is a block diagram showing the configuration of the lost property detection system according to the embodiment 1. Fig. 2 is a block diagram showing the configuration of the lost property detection device and the mobile terminal in the lost property detection system according to the embodiment 1.

The lost property detection system 1 is a system that detects items left behind on a vehicle 2 (see FIG. 1). Examples of the vehicle 2 include public transportation such as a bus, train, ship, or airplane. The vehicle 2 is equipped with luggage racks 10A-10N in each designated section. The lost property detection system 1 includes luggage racks 10A-10N and a mobile terminal 30.

The luggage racks 10A to 10N are racks for placing luggage 3 (items that may be left behind) (see FIG. 1). The luggage racks 10A to 10N are equipped with corresponding identification information 11A to 11N and lost item detection devices 20A to 20N.

The identification information 11A-11N is unique information for identifying (specifying) the corresponding luggage rack 10A-10N (see FIG. 1). The identification information 11A-11N can be something visible, such as a string of numbers or letters, a barcode, or a QR (Quick Response: registered trademark) code. The identification information 11A-11N can be read by the holder (passenger) of the mobile terminal 30 and input to the mobile terminal 30 by operating the input unit 33, or the holder can operate the input unit 33 and input to the mobile terminal 30 from the camera unit 34.

The lost property detection devices 20A-20N are devices configured to detect the presence or absence of luggage 3 placed on the corresponding luggage shelves 10A-10N, and to notify the owner's mobile terminal 30 when luggage 3 has been left behind (see Figures 1 and 2). One lost property detection device 20A-20N is provided for each corresponding luggage shelf 10A-10N. The lost property detection devices 20A-20N include a luggage detection unit 21, a wireless communication unit 22, a memory unit 23, and a control unit 24.

The luggage detection unit 21 is a functional unit that automatically detects when luggage 3 is placed on the corresponding luggage shelf 10A-10N (see FIG. 2). The luggage detection unit 21 can be implemented using sensors such as pressure sensors and optical sensors. The luggage detection unit 21 is controlled by the control unit 24. Under the control of the control unit 24, the luggage detection unit 21 provides the control unit 24 with luggage information regarding whether luggage 3 has been detected on the luggage shelf (for example, 10A). The luggage information includes information indicating that luggage is present and information indicating that luggage is not present.

The wireless communication unit 22 is a functional unit that performs wireless communication with the mobile terminal 30 (see FIG. 2). For example, the wireless communication unit 22 may use BLE (Bluetooth Low Energy: registered trademark). The wireless communication unit 22 is controlled by the control unit 24.

The memory unit 23 is a functional unit that stores information such as data and programs (see FIG. 2). The memory unit 23 stores identification information (corresponding to identification information 11A to 11N) related to the lost property detection device (20A to 20N) itself. The memory unit 23 is controlled by the control unit 24. Under the control of the control unit 24, the memory unit 23 associates and stores identification information related to the mobile terminal 30 with identification information (corresponding to identification information 11A to 11N) related to the lost property detection device (20A to 20N) itself.

The control unit 24 is a functional unit that controls the baggage detection unit 21, the wireless communication unit 22, and the storage unit 23 (see FIG. 2). The control unit 24 executes a predetermined process by executing a predetermined program stored in the storage unit 23. The control unit 24 receives identification information related to the mobile terminal 30 through the wireless communication unit 22, associates the identification information related to the mobile terminal 30 with the identification information related to the lost property detection device (20A-20N) itself (corresponding to the identification information 11A-11N) stored in the storage unit 23, and stores the associated identification information in the storage unit 23, thereby wirelessly connecting the lost property detection device (20A-20N) itself and the mobile terminal 30. When the control unit 24 receives baggage inquiry information from the mobile terminal 30, it performs a process of acquiring baggage information from the baggage detection unit 21 and transmitting the baggage information to the mobile terminal 30.

The mobile terminal 30 is a portable information communication terminal owned by the owner of the luggage 3 (see Figures 1 and 2). For example, a smartphone or a tablet can be used as the mobile terminal 30. A program (dedicated application) for communicating with the lost property detection devices 20A to 20N is installed in the mobile terminal 30. The mobile terminal 30 includes a wireless communication unit 31, an output unit 32, an input unit 33, a camera unit 34, a memory unit 35, and a control unit 36.

The wireless communication unit 31 is a functional unit that performs wireless communication with the lost property detection devices 20A to 20N (see FIG. 2). The wireless communication unit 31 may perform wireless communication using BLE, for example. The wireless communication unit 31 is controlled by the control unit 36.

The output unit 32 is a functional unit that outputs information (display, audio output, vibration output, etc.) (see FIG. 2). A display, speaker, vibrator, etc. can be used as the output unit 32. The output unit 32 is controlled by the control unit 36. Under the control of the control unit 36, the output unit 32 outputs an alarm (for example, vibration output, warning sound output, sound ringing, display of a message on the screen) to notify the user that an item has been left behind.

The input unit 33 is a functional unit that inputs information (text input, voice input, etc.) (see FIG. 2). For example, a touch panel, a key operation unit, a microphone, etc. can be used as the input unit 33. The input unit 33 is controlled by the control unit 36.

The camera unit 34 is a functional unit that captures an image of a subject (obtains an image) (see FIG. 2). The camera unit 34 is controlled by the control unit 36. The camera unit 34 obtains images of the identification information 11A to 11N when the user operates the input unit 33.

The memory unit 35 is a functional unit that stores information such as data and programs (see FIG. 2). The memory unit 35 is controlled by the control unit 36.

The control unit 36 is a functional unit that controls the wireless communication unit 31, the output unit 32, the input unit 33, the camera unit 34, and the memory unit 35 (see FIG. 2). The control unit 36 executes a predetermined process by executing a predetermined program stored in the memory unit 35. The control unit 36 acquires identification information (e.g., 11A) relating to a luggage shelf (e.g., 10A) by a user operating the input unit 33. The control unit 36 transmits the identification information relating to the mobile terminal 30 to the lost property detection device 20A that corresponds to the acquired identification information relating to the luggage shelf 10A, and performs a process of wirelessly connecting the mobile terminal 30 and the lost property detection device 20A.

The control unit 36 performs a process of transmitting baggage inquiry information to a wirelessly connected lost property detection device (e.g., 20A) via the wireless communication unit 31 at regular intervals to inquire about the presence or absence of baggage 3 on the baggage shelf 10A. The control unit 36 receives baggage information from the lost property detection device (e.g., 20A) via the wireless communication unit 31, and determines whether the received baggage information indicates that there is baggage or that there is no baggage. When the baggage information indicates that there is baggage, the control unit 36 stores the baggage information in the memory unit 35.

When the received luggage information indicates that luggage is present, and the radio wave strength at the time of receiving the luggage information from the lost property detection device (e.g., 20A) falls below a preset threshold, the control unit 36 determines that the luggage 3 has been left behind, and processes the output unit 32 to output an alarm informing the owner that the luggage 3 has been left behind.

When the received luggage information indicates that luggage is missing, the control unit 36 processes the information so that an alarm is output from the output unit 32 to inform the owner that luggage 3 is missing if the radio wave strength at the time the luggage information is received from the lost property detection device (e.g., 20A) is equal to or greater than a preset threshold value.

Next, the operation of the mobile terminal in the lost property detection system according to the first embodiment will be described with reference to the drawings. FIG. 3 is a flow chart that shows the operation of the mobile terminal in the lost property detection system according to the first embodiment. Please refer to FIG. 1 and FIG. 2 for the configuration of the lost property detection system.

As a premise, the owner of luggage 3 boards vehicle 2, places luggage 3 on a luggage rack (here, 10A), and visually confirms identification information 11A (here, QR code (registered trademark)) attached to luggage rack 10A where the owner has placed luggage 3.

At this time, first, the control unit 36 of the mobile terminal 30 acquires the identification information 11A related to the luggage shelf 10A by having the holder, who has confirmed the identification information 11A, operate the input unit 33 to photograph the identification information 11A (QR code) related to the luggage shelf 10A with the camera unit 34 (step A1).

Next, the control unit 36 transmits the identification information related to the mobile terminal 30 to the lost item detection device 20A in the luggage shelf 10A related to the acquired identification information 11A via the wireless communication unit 31 (step A2).

Next, the control unit 36 wirelessly connects (e.g., BLE connects) the mobile terminal 30 to the lost item detection device 20A via the wireless communication unit 31 (step A3).

After step A3, or if the radio wave strength is equal to or greater than the threshold (NO in step A8), the control unit 36 transmits baggage inquiry information to the wirelessly connected lost property detection device 20A through the wireless communication unit 31 to inquire about the presence or absence of baggage 3 on the baggage shelf 10A (step A4). The transmission of the baggage inquiry information is performed at regular intervals.

Next, the control unit 36 receives baggage information from the lost property detection device (e.g., 20A) via the wireless communication unit 31 (step A5). The baggage information is a response to the baggage inquiry information in step A4.

Next, the control unit 36 judges whether the received luggage information indicates that luggage is present or absent (step A6). If the luggage information indicates that luggage is absent (NO in step A6), the process proceeds to step A10.

If the baggage information indicates that baggage is present (YES in step A6), the control unit 36 stores the baggage information (information indicating that baggage is present) in the memory unit 35 (step A7).

Next, the control unit 36 determines whether the radio wave strength at the time when the package information is received from the lost property detection device 20A is below a preset threshold (step A8). If the radio wave strength is equal to or greater than the threshold (NO in step A8), the process returns to step A4.

If the radio wave strength is below the threshold (YES in step A8), the control unit 36 determines that the holder has left the luggage 3 on the luggage shelf 10A (the holder has left the luggage shelf 10A to disembark), and causes the output unit 32 to output an alarm informing the holder that the luggage 3 has been left behind (step A9), and then ends the process.

If the baggage information indicates that there is no baggage (NO in step A6), the control unit 36 judges whether the radio wave strength at the time when the baggage information was received from the lost property detection device 20A is below a preset threshold (step A10). If the radio wave strength is below the threshold (YES in step A10), it is determined that the owner has removed the baggage 3 from the baggage shelf 10A and disembarked, and the process ends.

If the radio wave strength is equal to or greater than the threshold (NO in step A10), the control unit 36 causes the output unit 32 to output an alarm notifying the holder that luggage 3 has disappeared from the luggage shelf 10A (step A11), and then ends the process. Note that if the radio wave strength is equal to or greater than the threshold and luggage 3 has disappeared from the luggage shelf 10A, the holder may be taking luggage 3 off the luggage shelf 10A, so the system may be switched so that the alarm notifying the holder that luggage 3 has disappeared is not output.

Next, the operation of the lost item detection device in the lost item detection system according to the first embodiment will be described with reference to the drawings. FIG. 4 is a flow chart that shows a schematic of the operation of the lost item detection device in the lost item detection system according to the first embodiment. Please refer to FIG. 1 and FIG. 2 for the configuration of the lost item detection system.

As a premise, it is assumed that the owner of the luggage 3 boards the vehicle 2, places the luggage 3 on a luggage rack (here, 10A), and acquires, via the mobile terminal 30, the identification information 11A relating to the luggage rack 10A on which the owner has placed the luggage 3.

First, the control unit 24 of the lost property detection device 20A receives identification information related to the mobile terminal 30 from the mobile terminal 30 via the wireless communication unit 22 (step B1).

Next, the control unit 24 associates the identification information related to the mobile terminal 30 with the identification information related to the lost property detection device 20A itself (corresponding to the identification information 11A) stored in the memory unit 23 and registers them in the memory unit 23 (step B2).

Next, the control unit 24 wirelessly connects the lost item detection device 20A to the mobile terminal 30 (step B3).

After step B3, or if the parcel information indicates that parcel is present (YES in step B7), the control unit 24 receives parcel inquiry information from the mobile terminal 30 (step B4).

Next, the control unit 24 causes the baggage detection unit 21 to detect baggage information in response to the received baggage inquiry information (step B5). The baggage information is information indicating whether baggage is present or not.

Next, the control unit 24 acquires the baggage information from the baggage detection unit 21 and transmits it to the mobile terminal 30 (step B6).

Next, the control unit 24 checks whether the acquired luggage information indicates that luggage is present (step B7). If the luggage information indicates that luggage is present (YES in step B7), the process returns to step B4. If the luggage information indicates that luggage is not present (NO in step B7), the process ends.

According to the first embodiment, the lost property detection devices 20A to 20N are not equipped with equipment such as cameras or in-vehicle displays for identifying individuals, and can detect the leaving of luggage 3 without placing a device in the luggage 3, which contributes to preventing luggage from being left behind on vehicles while keeping costs down and reducing the management burden on the owner.

In addition, according to the first embodiment, the owner of the luggage 3 can be notified of the luggage being left behind by vibration or a message displayed on the screen of the mobile terminal 30 carried by the owner, so that the owner can avoid being notified of the luggage being left behind by an alarm sound, which prevents other passengers from feeling uncomfortable and prevents the owner from being affected by surrounding noise.

[Embodiment 2]
The lost-item detection system according to the second embodiment will be described with reference to the drawings. Fig. 5 is a block diagram showing a schematic configuration of a lost-item detection device, a mobile terminal, and their peripherals in the lost-item detection system according to the second embodiment.

The second embodiment is a modification of the first embodiment, in which an Internet communication unit 25 is added to the lost property detection devices 20A to 20N, and the lost property detection devices 20A to 20N are configured to be able to communicate with an external management server 40 via a network 50.

Personal information such as the name and contact details (telephone number, email address) of the owner of luggage 3 is sent from the mobile terminal 30 to a lost property detection device (e.g., 20A) of the luggage shelf (e.g., 10A) where luggage 3 is placed. The lost property detection device 20A sends the received personal information, luggage identification information (which may include the name of the transportation vehicle) including the date and time when luggage 3 was placed and identification information related to luggage shelf 10A, to the management server 40 via the Internet communication unit 25 and the network 50. The management server 40 registers the received luggage identification information as history in its internal memory area. The other configurations and operations are the same as those of the first embodiment.

According to the second embodiment, as in the first embodiment, it is possible to reduce costs while reducing the burden of management on the owner, thereby contributing to preventing luggage from being left behind on a vehicle, and even if the owner gets off the vehicle without realizing that luggage 3 has been left behind, the owner of the luggage can be tracked by referring to the history registered in the management server 40.

[Embodiment 3]
The following describes a lost item detection system according to the third embodiment with reference to the drawings. Fig. 6 is a block diagram showing a schematic configuration of a lost item detection device, a mobile terminal, and their peripherals in the lost item detection system according to the third embodiment.

Embodiment 3 is a modification of embodiment 1, in which, instead of the identification information (11A to 11N in FIG. 1), RFID (Radio Frequency Identification) tags 12A to 12N are used, from which identification information can be read by wireless communication. The mobile terminal 30 further includes an RFID reader unit 37 capable of reading the identification information related to the RFID tag 12A. The identification information related to the RFID tag 12A is read by the RFID reader unit 37 when the holder of the luggage 3 operates the input unit 33 of the mobile terminal 30, and is then input to the mobile terminal 30. The identification information (related to the luggage shelves 10A to 10N) input to the mobile terminal 30 is used in the same way as in embodiment 1. The other configurations and operations are the same as in embodiment 1. Furthermore, embodiment 3 may be applied to embodiment 2.

As with embodiment 1, embodiment 3 can reduce costs while reducing the burden of management on the owner, helping to prevent luggage from being left behind on vehicles, and by using RFID tags 12A-12N and RFID reader unit 37, identification information related to luggage shelves 10A-10N can be easily input to mobile terminal 30.

[Embodiment 4]
The left-behind item detection system according to the fourth embodiment will be described with reference to the drawings. Fig. 7 shows an example of a luggage shelf selection screen displayed on a mobile terminal in the left-behind item detection system according to the fourth embodiment.

The fourth embodiment is a modification of the first and third embodiments, and instead of acquiring identification information related to a specific luggage shelf (10A-10N in Figs. 2 and 6) using the input unit (33 in Figs. 2 and 6), camera unit (34 in Figs. 2 and 6), and RFID reader unit (37 in Fig. 6) of the mobile terminal (30 in Figs. 2 and 6), the luggage shelf is selected from among the luggage shelves related to one or more lost property detection devices that have transmitted a response beacon signal in response to the transmission beacon emitted from the mobile terminal 30. The mobile terminal (30 in Fig. 2) displays a list screen of luggage shelves (luggage shelves related to the lost property detection devices that have transmitted the response beacon signal) as shown in Fig. 7 on the output unit (32 in Fig. 2), and has the holder operate the input unit (33 in Fig. 2) to select a luggage shelf. The identification information related to the selected luggage shelf is used in the same way as in the first embodiment. The other configurations are the same as in the first embodiment. The fourth embodiment may also be applied to the second embodiment.

Next, the operation of the mobile terminal in the lost property detection system according to the fourth embodiment will be described with reference to the drawings. FIG. 8 is a flow chart that shows the operation of the mobile terminal in the lost property detection system according to the fourth embodiment. Please refer to FIG. 1 and FIG. 2 for the configuration of the lost property detection system.

First, the control unit 36 of the mobile terminal 30 transmits a transmission beacon signal to the lost property detection devices 20A to 20N through the wireless communication unit 31 (step C1). At this time, the transmission beacon signal is transmitted without identifying the lost property detection devices 20A to 20N.

Next, the control unit 36 receives a response beacon signal (responding to the beacon signal transmitted in step C1) from one of the lost property detection devices 20A-20N through the wireless communication unit 31 (step C2). Here, the response beacon signal contains identification information for the luggage rack 10A-10N corresponding to the lost property detection device 20A-20N.

Next, the control unit 36 creates a list screen of luggage shelves (luggage shelves associated with the lost property detection device that transmitted the response beacon signal) based on the identification information associated with luggage shelves 10A-10N contained in the received response beacon signal, and displays it on the output unit (32 in FIG. 2) (step C3). Here, the list screen can be selected from the displayed luggage shelves by operating the input unit 33.

Next, the control unit 36 selects a luggage shelf (e.g., luggage shelf 10A) from the list screen by the owner of luggage 3 operating the input unit 33 (step C4).

Next, the control unit 36 transmits the identification information related to the mobile terminal 30 to the lost item detection device 20A related to the selected luggage shelf 10A via the wireless communication unit 31 (step C5).

Next, the control unit 36 wirelessly connects (e.g., BLE connects) the mobile terminal 30 and the lost-item detection device 20A via the wireless communication unit 31 (step C6). Note that even after wirelessly connecting the mobile terminal 30 and the lost-item detection device 20A, the control unit 36 continues to transmit an outgoing beacon signal to the lost-item detection device 20A via the wireless communication unit 31 at regular intervals.

After step C6, or if there is a response beacon signal (NO in step C11), the control unit 36 transmits baggage inquiry information to the wirelessly connected lost property detection device 20A through the wireless communication unit 31 to inquire about the presence or absence of baggage 3 on the baggage shelf 10A (step C7). The baggage inquiry information is transmitted at regular intervals.

Next, the control unit 36 receives baggage information from the lost property detection device (e.g., 20A) via the wireless communication unit 31 (step C8). The baggage information is a response to the baggage inquiry information in step C7.

Next, the control unit 36 determines whether the received luggage information indicates that luggage is present or absent (step C9). If the luggage information indicates that luggage is absent (NO in step C9), the control unit 36 proceeds to step C13.

If the baggage information indicates that baggage is present (YES in step C9), the control unit 36 stores the baggage information (information indicating that baggage is present) in the memory unit 35 (step C10).

Next, the control unit 36 determines whether the response beacon signal from the lost property detection device 20A has disappeared due to exceeding the wireless communication distance (step C11). If the response beacon signal is present (NO in step C11), the process returns to step C7.

If there is no response beacon signal (YES in step C11), the control unit 36 determines that the holder has left the luggage 3 on the luggage shelf 10A (the holder has left the luggage shelf 10A to disembark), and causes the output unit 32 to output an alarm informing the holder that the luggage 3 has been left behind (step C12), and then ends the process.

If the baggage information indicates that there is no baggage (NO in step C9), the control unit 36 judges whether the response beacon signal from the lost property detection device 20A has disappeared due to exceeding the range of wireless communication (step C13). If there is no response beacon signal (YES in step C13), it is determined that the owner has removed the baggage 3 from the baggage shelf 10A and disembarked, and the process ends.

If there is a response beacon signal (NO in step C13), the control unit 36 causes the output unit 32 to output an alarm informing the holder that the luggage 3 has disappeared from the luggage shelf 10A (step C14), and then ends the process. Note that if there is a response beacon signal and the luggage 3 has disappeared from the luggage shelf 10A, the holder may be taking the luggage 3 off the luggage shelf 10A, so the system may be switched so that the alarm informing the holder that the luggage 3 has disappeared is not output.

Other operations are the same as in embodiment 1.

According to the fourth embodiment, as in the first embodiment, it is possible to reduce costs while reducing the burden of management on the owner, thereby contributing to preventing luggage from being left behind on vehicles, and by selecting a luggage shelf from a list screen of luggage shelves related to the lost property detection device that has transmitted a response beacon signal, it is possible to easily input identification information related to luggage shelves 10A to 10N into the mobile terminal 30.

[Embodiment 5]
A lost-item detection system according to the fifth embodiment will be described with reference to the drawings. Fig. 9 is a block diagram showing a schematic configuration of the lost-item detection system according to the fifth embodiment.

The lost property detection system 1 is a system that detects whether luggage 3 placed on luggage shelves 10A to 10N has been left behind. The lost property detection system 1 includes multiple luggage shelves 10A to 10N and a mobile terminal 30.

The luggage shelves 10A to 10N are shelves on which luggage 3 can be placed. The luggage shelves 10A to 10N are equipped with lost property detection devices 20A to 20N and identification information 11A to 11N relating to the luggage shelves 10A to 10N themselves.

The lost property detection devices 20A to 20N are devices that detect whether luggage 3 placed on the luggage shelves 10A to 10N has been left behind. The lost property detection devices 20A to 20N include a luggage detection unit 21, a wireless communication unit 22, and a control unit 24.

The luggage detection unit 21 is configured to detect luggage 3 placed on luggage shelves 10A to 10N. The wireless communication unit 22 is configured to be capable of wireless communication with the mobile terminal 30. The control unit 24 is configured to control the luggage detection unit 21 and the wireless communication unit 22, and to perform predetermined information processing.

When the control unit 24 receives identification information related to the mobile terminal 30 from the mobile terminal 30 via the wireless communication unit 22, it performs a process of wirelessly connecting the lost property detection devices 20A-20N themselves to the mobile terminal 30. In response to baggage inquiry information from the mobile terminal 30 inquiring about the presence or absence of baggage 3 on the baggage shelves 10A-10N, the control unit 24 performs a process of causing the baggage detection unit 21 to detect baggage information and transmitting the baggage information to the mobile terminal 30.

The mobile terminal 30 is a portable information processing terminal used by the owner of the baggage 3. The mobile terminal 30 includes a wireless communication unit 31 and an output unit 32.

The wireless communication unit 31 is configured to be capable of wireless communication with the lost property detection devices 20A-20N provided on the luggage shelves 10A-10N. The acquisition unit 38 is configured to acquire the identification information 11A-11N assigned to the luggage shelves 10A-10N. The acquisition unit 38 corresponds to any of the input unit 33, camera unit 34 in FIG. 2, and RFID reader unit 37 in FIG. 6. The output unit 32 is configured to output information. The control unit 36 is configured to control the wireless communication unit 31, acquisition unit 38, and output unit 32, and to perform predetermined information processing.

When the control unit 36 acquires the identification information 11A-11N relating to the luggage shelves 10A-10N through the acquisition unit 38, the control unit 36 transmits the identification information relating to the mobile terminal 30 itself to the lost property detection device 20A-20N corresponding to the acquired identification information relating to the luggage shelves 10A-10N through the wireless communication unit 31, and performs a process of wirelessly connecting the mobile terminal 30 itself to the lost property detection device 20A-20N. The control unit 36 performs a process of transmitting baggage inquiry information inquiring about the presence or absence of luggage 3 on the luggage shelves 10A-10N to the lost property detection device 20A-20N through the wireless communication unit 31. When the control unit 36 receives luggage information from the lost property detection device 20A-20N through the wireless communication unit 31, it performs a process of determining whether the luggage information is information about the presence of luggage or information about the absence of luggage. When the luggage information is information about the presence of luggage, the control unit 36 performs a process of determining whether the radio wave intensity at the time of receiving the luggage information is below a preset threshold value. When the radio wave strength is below the threshold, the control unit 36 performs processing to cause the output unit 32 to output an alarm notifying the user that luggage 3 has been left behind on luggage shelves 10A to 10N.

According to the fifth embodiment, the lost property detection devices 20A to 20N are not equipped with equipment such as cameras or in-vehicle displays for identifying individuals, and can detect the leaving of luggage 3 without placing a device in the luggage 3, thereby reducing the management burden on the owner and contributing to preventing luggage from being left behind on vehicles while keeping costs down.

The lost property detection device and mobile terminal according to the first to fifth embodiments can be configured with so-called hardware resources (information processing device, computer), and a device having the configuration shown in FIG. 10 can be used. For example, the hardware resource 100 includes a processor 101, a memory 102, a network interface 103, etc., which are connected to each other by an internal bus 104.

Note that the configuration shown in FIG. 10 is not intended to limit the hardware configuration of the hardware resource 100. The hardware resource 100 may include hardware (e.g., an input/output interface) that is not shown. Furthermore, the number of units such as the processor 101 included in the device is not intended to be limited to the example shown in FIG. 10, and for example, multiple processors 101 may be included in the hardware resource 100. The processor 101 may be, for example, a CPU (Central Processing Unit), an MPU (Micro Processor Unit), a GPU (Graphics Processing Unit), etc.

Memory 102 may be, for example, a RAM (Random Access Memory), a ROM (Read Only Memory), a HDD (Hard Disk Drive), or a SSD (Solid State Drive).

The network interface 103 may be, for example, a LAN (Local Area Network) card, a network adapter, a network interface card, etc.

The functions of the hardware resource 100 are realized by the above-mentioned processing module. The processing module is realized, for example, by the processor 101 executing a program stored in the memory 102. The program can be downloaded via a network or updated using a storage medium on which the program is stored. Furthermore, the processing module may be realized by a semiconductor chip. In other words, it is sufficient that the functions performed by the processing module are realized by the execution of software in some kind of hardware.
