[0009] Hereinafter, an embodiment of a control device to which the present disclosure is applied will be described with reference to the drawings.

[0010] 1, a monitoring system 11 including a control device 10 according to an embodiment may include at least one moving object 12, at least one terminal device (terminal) 13, and the control device 10. In FIG. 1, two moving objects 12 and three terminal devices 13 are depicted, but this is by way of example and is not limiting.

[0011] The mobile object 12 may communicate with a terminal device 13 carried by a passenger aboard the mobile object 12. The mobile object 12 may communicate with the control device 10 via a network 14. The control device 10 transmits first identification information as information to the terminal device 13 via the mobile object 12. In response to an abnormality notification from the terminal device 13 that transmitted the first identification information, the control device 10 captures an image of an arbitrary position inside the mobile object 12. Detailed configurations of the mobile object 12, the terminal device 13, and the control device 10 are described below.

[0012] The moving body 12 may include, for example, vehicles, ships, and aircraft. The vehicles may include, for example, automobiles, railroad vehicles, residential vehicles, and fixed-wing aircraft that run on runways. The automobiles may include, for example, passenger cars, trucks, buses, motorcycles, and trolley buses. The classification of vehicles is not limited to the above examples. For example, automobiles may include industrial vehicles that can run on roads. The same vehicle may be included in multiple classifications. The ships may include, for example, marine jets, boats, and tankers. The aircraft may include, for example, fixed-wing aircraft and rotary-wing aircraft. The moving body 12 may have a boarding space for a relatively large number of passengers, for example, 10 or more people.

[0013] 2, the mobile object 12 may include a communication device 15, a boarding / alighting registration unit 16, at least three antennas 17, and an imaging unit 18. The communication device 15 is connected to the boarding / alighting registration unit 16, the antenna 17, and the imaging unit 18 so as to be able to communicate with each other via an in-vehicle network or a dedicated line.

[0014] The communication device 15 may be an in-vehicle communication device. The communication device 15 may include a communication module that connects to the network 14. The communication device 15 may include a communication module that supports a mobile communication standard. The communication device 15 is connected to the control device 10 via the network 14. When transmitting information to the control device 10, the communication device 15 may add second identification information that identifies the mobile object 12 to the information. The communication device 15 may include a communication module that communicates via an in-vehicle network or a dedicated line. The communication device 15 may transmit information or commands received from the control device 10 to the boarding and disembarking registration unit 16, the antenna 17, and the imaging unit 18.

[0015] The boarding / disembarking registration unit 16 may include a communication module capable of short-distance wireless communication such as NFC (Near Field Communication). The boarding / disembarking registration unit 16 may be provided near the boarding / disembarking door 19 of the mobile body 12. The boarding / disembarking registration unit 16 may have a communication surface. When a passenger boards the mobile body 12, the boarding condition may be determined to be that the terminal device 13 is brought close to the communication surface, for example, to a distance of 10 cm or less. When a passenger disembarks from the mobile body 12, the disembarking condition may be determined to be that the terminal device 13 is brought close to the communication surface, for example, to a distance of 10 cm or less. When the terminal device 13 capable of short-distance wireless communication approaches the communication surface, a command to transmit or delete the first identification information to the terminal device 13 may be transmitted, as will be described in detail later. The first identification information is identification information used locally to identify the terminal device 13 located in each mobile body 12.

[0016] Each of the multiple antennas 17 may be provided at a different position of the mobile body 12. The antenna 17 may include a communication module capable of wirelessly communicating with the terminal device 13. When transmitting information to the terminal device 13, the antenna 17 may add third identification information for identifying the antenna 17 to the information.

[0017] The imaging unit 18 may be provided so as to be able to image the boarding space in the moving body 12. The imaging unit 18 may include at least one imaging device. The imaging device may be installed in the moving body 12. The imaging unit 18 may include a plurality of imaging devices having different imaging ranges. The imaging device may be optically variable in magnification. The imaging unit 18 may include a motor capable of changing the optical axis direction of the imaging device. The imaging unit 18 may adjust a specific area to a state in which it can be imaged, for example, by changing the optical axis direction of the imaging device based on a command from the control device 10 via the communication device 15. The imaging unit 18 may acquire only an image of a specific area from among the imaging-capable areas of the imaging device based on a command from the control device 10 via the communication device 15.

[0018] The imaging device may capture an image of an arbitrarily designated position within the moving body 12 based on an imaging command from the control device 10. The imaging device may transmit the captured image to the control device 10 via the communication device 15.

[0019] 3, the terminal device 13 may include a biosensor unit 20, a direction sensor 21, a display unit 22, an input unit 23, a communication unit 24, a storage unit 25, and a control unit 26. The terminal device 13 is a device that can be carried by a passenger and is capable of wireless communication and short-range wireless communication. The terminal device 13 is, for example, a smartphone or a smart watch.

[0020] The biosensor unit 20 includes at least one biosensor that detects bioinformation of a passenger carrying the terminal device 13. The biosensor may be, for example, a sensor that detects the passenger's heart rate, activity level, blood oxygen saturation, pulse wave, activity level, body temperature, etc.

[0021] The orientation sensor 21 may detect in which direction on the ground the direction determined in the terminal device 13 is facing. The direction determined in the terminal device 13 may be, for example, the upward direction of the display unit 22 of the terminal device 13.

[0022] The display unit 22 may display an image. The display unit 22 is, for example, a panel display such as a liquid crystal display or an organic EL display.

[0023] The input unit 23 includes one or more input interfaces that detect user input. For example, the input interfaces included in the input unit 23 are physical keys, capacitive keys, and a touch screen that is integral with the display unit 22.

[0024] The communication unit 24 may include at least a communication module capable of short-range wireless communication. The communication unit 24 may perform short-range wireless communication with the boarding / disembarking registration unit 16. The communication unit 24 may include a communication module capable of wireless communication with the antenna 17. The communication unit 24 may detect the radio wave intensity of a signal wave radiated from each of the multiple antennas 17 in the mobile body 12. When transmitting information from the terminal device 13 to the control device 10, the communication unit 24 may add fourth identification information defined for the terminal device 13. The fourth identification information may be, for example, unique information capable of uniquely identifying the terminal device 13.

[0025] The storage unit 25 includes any storage device, such as, for example, a random access memory (RAM) or a read only memory (ROM). The storage unit 25 may store various programs that cause the control unit 26 to function, and various information used by the control unit 26. The storage unit 25 may store, for example, first identification information transmitted to the terminal device 13, the radio wave intensity of the radio wave received from each antenna 17, and third identification information of the antenna 17.

[0026] The control unit 26 includes one or more processors and memories. The processor may include a general-purpose processor that loads a specific program to execute a specific function, and a dedicated processor specialized for a specific process. The dedicated processor may include an application specific integrated circuit (ASIC). The processor may include a programmable logic device (PLD). The PLD may include a field-programmable gate array (FPGA). The control unit 26 may be either a system-on-a-chip (SoC) or a system in a package (SiP) in which one or more processors work together.

[0027] When the control unit 26 can wirelessly communicate with the boarding / alighting registration unit 16, the control unit 26 may determine whether or not the first identification information transmitted from the boarding / alighting registration unit 16 is stored in the storage unit 25. When the first identification information is not stored in the storage unit 25, the control unit 26 may notify the boarding / alighting registration unit 16 that the boarding status is a boarding status. The control unit 26 may store the first identification information transmitted from the boarding / alighting registration unit 16 after the notification in the storage unit 25. When the first identification information is stored in the storage unit 25, the control unit 26 may notify the boarding / alighting registration unit 16 that the first identification information is or that the boarding / alighting registration unit 16 is in a leaving status. The control unit 26 may delete the first identification information from the storage unit 25 based on a deletion command transmitted from the boarding / alighting registration unit 16 after the notification.

[0028] After receiving the first identification signal, the control unit 26 may associate the first identification information with the information and transmit it to the control device 10 via the boarding / alighting registration unit 16 or the antenna 17 and the communication device 15.

[0029] The control unit 26 may calculate the position of the terminal device 13 in the mobile body 12 based on the positions of the multiple antennas 17 provided in the mobile body 12 on which the terminal device 13 is riding, which is acquired as information from the control device 10, and the radio wave intensity of each of the multiple antennas 17, which is read from the storage unit 25. The control unit 26 may store the calculated position as information in the storage unit 25. In response to a notification request from the control device 10, the control unit 26 may transmit the position as information to the control device 10. Alternatively, the control unit 26 may periodically transmit the position as information to the control device 10.

[0030] Alternatively, the control unit 26 may store the radio wave intensity of radio waves received from the multiple antennas 17 in the mobile body 12 as information in the storage unit 25 in association with the third identification information of each antenna 17 in order to have the control device 10 calculate the position of the terminal device 13. In response to a notification request from the control device 10, the control unit 26 may transmit the latest radio wave intensity of the multiple antennas 17 as information and the respective third identification information stored in the storage unit 25 to the control device 10. Alternatively, the control unit 26 may periodically transmit the latest radio wave intensity of the multiple antennas 17 as information and the respective third identification information stored in the storage unit 25 to the control device 10.

[0031] The control unit 26 may transmit the abnormality notification to the control device 10 via the communication unit 24 and the communication device 15. The transmission of the abnormality notification will be described below.

[0032] When the input unit 23 detects an input of an assistance request, the control unit 26 may control the communication unit 24 to transmit an abnormality notification to the control device 10.

[0033] The control unit 26 may analyze the bioinformation acquired from the biosensor unit 20. The control unit 26 may determine whether or not a biologic abnormality has occurred in the person carrying the terminal device 13, in other words, the passenger, based on the analysis of the biologic information. When the control unit 26 determines that a biologic abnormality has occurred, the control unit 26 may control the communication unit 24 to transmit an abnormality notification to the control device 10. Alternatively, when the control unit 26 determines that a biologic abnormality has occurred, the control unit 26 may display an image requesting input of whether or not an assistance request is required on the display unit 22, as shown in FIG. 4, before transmitting the abnormality notification. When the input unit 23 detects an input of an assistance request during the display of the image, the control unit 26 may transmit the abnormality notification to the control device 10. Also, when the input unit 23 does not detect an input of whether or not an assistance request is required until a predetermined time has elapsed after the image is displayed, the control unit 26 may transmit the abnormality notification to the control device 10.

[0034] The control unit 26 may transmit the biological information to the control device 10 to have the control device 10 analyze the biological information. When the control unit 26 receives information indicating the occurrence of a biological abnormality from the control device 10 in response to the transmission of the biological information, the control unit 26 may cause the display unit 22 to display an image requesting input of whether or not a request for assistance is required. After displaying the image, the control unit 26 may execute the same process as the configuration in which the terminal device 13 executes the analysis of the biological information.

[0035] When the input unit 23 detects an input of the occurrence of a surrounding abnormality, the control unit 26 may cause the display unit 22 to display a notification image requesting a suggestion of the location where the abnormality has occurred. The notification image is an image that can specify any position inside the mobile object 12.

[0036] The notification image may be a first notification image indicating the position ps of the other passenger in the moving body 12, as shown in FIG. 5. The control unit 26 may display the first notification image by a browser or a dedicated application. In a configuration in which the image is displayed by a browser, the first notification image may be provided by the control device 10. In a configuration in which the image is displayed by an application, the first notification image may be created by the control unit 26 based on information such as the position ps of the other passenger in the moving body 12 and the dimensions of the boarding space of the moving body 12 received from the control device 10. In the first notification image, the position ps of the other passenger may be displayed as a request for suggestion of the abnormality occurrence position. When the input unit 23 detects an input specifying any of the positions ps of the other passengers in the first notification image, the control unit 26 may transmit the position ps to the control device 10 as information on an arbitrarily specified position. When the input unit 23 detects an input specifying a position other than the position ps of the other passenger, the control unit 26 may transmit the position to the control device 10 as information on an arbitrarily specified position.

[0037] Alternatively, the notification image may be a second notification image depicting the boarding space of the moving object 12 as shown in FIG. 6. The control unit 26 may display the second notification image by a browser or a dedicated application. In a configuration in which the image is displayed by a browser, the second notification image may be provided by the control device 10. In a configuration in which the image is displayed by an application, the second notification image may be created by the control unit 26 based on information such as the dimensions of the boarding space of the moving object 12 received from the control device 10. When the input unit 23 detects an input specifying a position in the second notification image, the control unit 26 may transmit the position to the control device 10 as information on an arbitrarily specified position.

[0038] Alternatively, the notification image may be a third notification image requesting the user to specify the direction in which the abnormality occurs, as shown in FIG. 7. The user of the terminal device 13 may change the direction of the terminal device 13 to specify the direction in which the abnormality occurs. The user of the terminal device 13 may use a touch panel to change the direction of a designation image (e.g., an arrow) included in the third notification image to specify the direction in which the abnormality occurs. The control unit 26 may display the third notification image using a browser or a dedicated application. In a configuration in which the third notification image is displayed using a browser, the third notification image may be transmitted from the control device 10. In a configuration in which the third notification image is displayed using an application, the third notification image may be created in the control unit 26. After the third notification image is displayed, if a predetermined determination time or more has elapsed with a predetermined direction designated, the control unit 26 may transmit the direction in the moving body 12 indicated by the designated direction to the control device 10 as information on the direction in which the abnormality occurs, which may designate any position.

[0039] 1, the control device 10 includes a control unit 27. The control device 10 may further include a communication unit 28 and a storage unit 29. The control device 10 may be, for example, a server device.

[0040] The communication unit 28 may include a communication module that connects to the network 14. The communication unit 28 includes, for example, a communication module that complies with a wired LAN (Local Area Network) standard.

[0041] The storage unit 29 includes any storage device such as a RAM, a ROM, etc. The storage unit 29 may store various programs that cause the control unit 27 to function, and various information used by the control unit 27. The storage unit 29 stores, for example, first identification information assigned to the terminal device 13 for each mobile object 12. Assignment may mean allocating a first identification number to the terminal device 13.

[0042] The control unit 27 includes one or more processors and memories. The processor may include a general-purpose processor that loads a specific program to execute a specific function, and a dedicated processor specialized for a specific process. The dedicated processor may include an application-specific IC. The processor may include a PLD. The PLD may include an FPGA. The control unit 27 may be either an SoC or a SiP in which one or more processors work together.

[0043] When a passenger boards the moving body 12, the control unit 27 assigns first identification information to the terminal device 13 of the passenger. In the boarding condition as described above, it is assumed that the passenger brings the terminal device 13 carried by the passenger into close proximity to the boarding / disembarking registration unit 16 when boarding the moving body 12. For example, the control unit 27 may determine that the passenger boards the moving body 12 when it acquires information indicating that the passenger is in a boarding situation via the boarding / disembarking registration unit 16 and the communication device 15. In addition, for example, the control unit 27 may determine that the passenger boards the moving body 12 when the fourth identification information acquired via the boarding / disembarking registration unit 16 and the communication device 15 is not stored in the storage unit 29. The control unit 27 may assign first identification information that is different from the first identification information of other terminal devices 13 stored in the storage unit 29 for the same moving body 12 at the time of newly assigning the first identification information.

[0044] The control unit 27 may store the first identification information assigned to the terminal device 13 in the storage unit 29. The control unit 27 may acquire second identification information from the communication device 15 together with the first identification information. Furthermore, the control unit 27 may acquire fourth identification information from the terminal device 13 together with the first identification information. The control unit 27 may store the acquired second identification information and fourth identification information in the storage unit 29 in association with the first identification information.

[0045] The control unit 27 may transmit the first identification information assigned to the terminal device 13 to the terminal device 13 via the communication device 15 and the boarding / disembarking registration unit 16.

[0046] When a passenger leaves the moving body 12, the control unit 27 may delete the first identification information assigned to the terminal device 13 of the passenger from the storage unit 29. In the disembarking condition as described above, it is assumed that the passenger brings the terminal device 13 carried by the passenger into close proximity to the boarding / disembarking registration unit 16 when leaving the moving body 12. For example, when the control unit 27 acquires information indicating that the passenger is leaving via the boarding / disembarking registration unit 16 and the communication device 15, the control unit 27 may determine that the passenger will leave the moving body 12. Also, for example, when at least one of the first identification information and the fourth identification information acquired via the boarding / disembarking registration unit 16 and the communication device 15 is stored in the storage unit 29, the control unit 27 may determine that the passenger will leave the moving body 12.

[0047] Furthermore, when the passenger leaves the moving body 12, the control unit 27 may transmit to the terminal device 13 a command to delete from the terminal device 13 the first identification information transmitted to the terminal device 13. The control unit 27 may delete from the storage unit 29 the fourth identification information stored in association with the first identification information together with the first identification information.

[0048] When the control unit 27 receives any information from the terminal device 13 via the antenna 17 and the communication device 15, the control unit 27 compares the information with the first identification information stored in the storage unit 29 to determine whether or not the first identification information has been assigned to the terminal device 13. For example, the control unit 27 may make the determination by comparing the first identification information received together with the any information from the terminal device 13 with the first identification information stored in the storage unit 29. Also, for example, the control unit 27 may make the determination by comparing whether or not the first identification information associated with the fourth identification information received together with the any information from the terminal device 13 exists in the storage unit 29. The any information may be an abnormality notification.

[0049] The control unit 27 may transmit a notification request for the position of the terminal device 13 in the mobile body 12 to the terminal device 13 to which the first identification information has been assigned, via the communication device 15 and the antenna 17. The control unit 27 may store the position of the terminal device 13 received from the terminal device 13 in response to the notification request as information in the storage unit 29 in association with the first identification information. Alternatively, in a configuration in which the control unit 27 periodically acquires the position from the terminal device 13 without making a notification request, the control unit 27 may store the position as information in the storage unit 29 in association with the first identification information assigned to the terminal device 13.

[0050] The control unit 27 may calculate the position of the terminal device 13 instead of the terminal device 13. Specifically, the control unit 27 may calculate the position of the terminal device 13 based on the radio wave intensity associated with each antenna 17 acquired from the terminal device 13 periodically or in response to a request for notification of the radio wave intensity. The control unit 27 may store the calculated position of the terminal device 13 as information in the storage unit 29 in association with the first identification information.

[0051] In response to an abnormality notification from the terminal device 13 to which the first identification information is assigned, the control unit 27 causes the imaging device to acquire an image of an arbitrary position inside the moving body 12 designated by the terminal device 13. The abnormality notification and the arbitrary position inside the moving body 12 designated by the terminal device 13 will be described below.

[0052] When the control unit 27 receives an abnormality notification from the terminal device 13 to which the assistance request has been input, the control unit 27 may cause the imaging device to acquire an image in response to the abnormality notification.

[0053] When the control unit 27 receives an abnormality notification from the terminal device 13 that has detected a biological abnormality, or an abnormality notification transmitted because a predetermined time has elapsed since the terminal device 13 detected a biological abnormality, the control unit 27 may cause the imaging device to acquire video in response to the abnormality notification.

[0054] When the control unit 27 receives biometric information from the terminal device 13, the control unit 27 may analyze the biometric information. The control unit 27 may determine whether or not a biometric abnormality has occurred in the person carrying the terminal device 13, in other words, the passenger, based on the analysis of the biometric information. When the control unit 27 determines that a biometric abnormality has occurred, the control unit 27 may conveniently determine that an abnormality notification has been transmitted from the terminal device 13. Alternatively, when the control unit 27 determines that a biometric abnormality has occurred, the control unit 27 may transmit information indicating that a biometric abnormality has occurred to the terminal device 13 that transmitted the biometric information. When the control unit 27 receives an abnormality notification in response to a transmission indicating that a biometric abnormality has occurred, or when the control unit 27 determines that the aforementioned abnormality notification has been transmitted, the control unit 27 may cause the imaging device to acquire an image in response to the abnormality notification.

[0055] The control unit 27 may receive the location within the moving object 12 from the terminal device 13 when receiving a request for assistance or an abnormality notification based on a biological abnormality.

[0056] When receiving a request for assistance or an abnormality notification based on a biological abnormality, the control unit 27 may acquire an image of the latest position of the terminal device 13 based on the position within the mobile body 12 periodically transmitted from the terminal device 13. As described above, grasping the position of the terminal device 13 may mean receiving the position as information from the terminal device 13, or calculating the position based on the radio wave intensity of the antenna 17 received from the terminal device 13.

[0057] In a configuration in which the position of the terminal device 13 in the mobile body 12 is not periodically received, the control unit 27 may, in response to receiving an assistance request or an abnormality notification based on a biological abnormality, make a request for notification of the position to the terminal device 13 that transmitted the abnormality notification. In response to the notification request, the control unit 27 may acquire the position of the terminal device 13 in the mobile body 12 as information from the terminal device 13. Alternatively, the control unit 27 may make a request for notification of radio wave strength to the terminal device 13 that transmitted the abnormality notification. The control unit 27 may calculate the position of the terminal device 13 based on the radio wave strength acquired from the terminal device 13 in response to the notification request.

[0058] When the control unit 27 receives an abnormality notification based on an input of the occurrence of a surrounding abnormality from the terminal device 13, the control unit 27 may cause the imaging device to acquire an image in response to the abnormality notification. In order to notify the control device 10 of the occurrence of a surrounding abnormality, the control unit 27 may transmit information for displaying a notification image on the terminal device 13 in response to a request from the terminal device 13. For example, the control unit 27 may transmit any one of a first notification image, a second notification image, and a third notification image as information to the terminal device 13. For example, in order to generate a first notification image in the terminal device 13, the control unit 27 may transmit the positions of all the terminal devices 13 in the moving body 12 and the dimensions of the boarding space of the moving body 12 as information to the terminal device 13. For example, in order to generate a second notification image in the terminal device 13, the control unit 27 may transmit the dimensions of the boarding space of the moving body 12 as information to the terminal device 13.

[0059] The control unit 27 may acquire an arbitrary position based on an operation on the terminal device 13 on which the first notification image, the second notification image, or the third notification image is displayed. The control unit 27 may cause the imaging device to acquire an image based on the arbitrary position. As described above, the control unit 27 acquires the arbitrarily designated position by transmitting the arbitrarily designated position itself as information from the terminal device 13 on which the first notification image or the second notification image is displayed. Alternatively, as described above, the control unit 27 acquires the arbitrarily designated position based on the direction in the moving body 12 transmitted from the terminal device 13 on which the third notification image is displayed, the position of the terminal device 13 in the moving body 12, and the positions of other terminal devices 13 in the moving body 12. Specifically, the control unit 27 may acquire the arbitrarily designated position by searching the storage unit 29 for other terminal devices 13 located in the direction in the receiving moving body 12 from the position of the terminal device 13 in the moving body 12.

[0060] Next, the first identification information management process executed by the control unit 27 in this embodiment will be described with reference to the flowchart of Fig. 8. The first identification information management process starts when communication is received from the boarding / alighting registration unit 16 via the communication device 15.

[0061] In step S100, the control unit 27 determines whether the passenger is about to board or leave the moving object 12. If the passenger is about to board, the process proceeds to step S101. If the passenger is about to leave, the process proceeds to step S103.

[0062] In step S101, the control unit 27 generates new first identification information. Furthermore, the control unit 27 associates the fourth identification information transmitted from the terminal device 13 via the boarding / alighting registration unit 16 and the communication device 15 with the generated first identification information and stores it in the storage unit 29. After storage, the process proceeds to step S102.

[0063] In step S102, the control unit 27 transmits the first identification information generated in step S101 to the terminal device 13 via the communication device 15 and the boarding / disembarking registration unit 16. After the transmission, the first identification information management process ends.

[0064] In step S103, the control unit 27 deletes the first identification information and the fourth identification information transmitted from the terminal device 13 via the boarding / alighting registration unit 16 and the communication device 15 from the storage unit 29. After the deletion, the process proceeds to step S104.

[0065] In step S104, the control unit 27 transmits a command to delete the first identification information to the terminal device 13 via the communication device 15 and the boarding / disembarking registration unit 16. After the transmission, the first identification information management process ends.

[0066] Next, the abnormality handling process executed by the control unit 27 in this embodiment will be described with reference to the flowchart of Fig. 9. The abnormality handling process starts when an abnormality notification is received.

[0067] In step S200, the control unit 27 determines whether the abnormality notification is based on a biological abnormality or an assistance request, or based on a surrounding abnormality. If the abnormality notification is based on a biological abnormality or an assistance request, the process proceeds to step S201. If the abnormality notification is based on a surrounding abnormality, the process proceeds to step S202.

[0068] In step S201, the control unit 27 acquires the location of the terminal device 13 that has transmitted the abnormality notification. The location may be acquired by receiving the location together with the abnormality notification. Alternatively, the location may be acquired by reading out the latest location of the first identification information from the storage unit 29 based on the first identification information acquired together with the abnormality notification. Alternatively, the location may be acquired by newly receiving the location of the terminal device 13 that has been given the first identification information acquired together with the abnormality notification in response to the transmission of a location notification request. After acquisition, the process proceeds to step S203.

[0069] In step S202, the control unit 27 acquires an arbitrarily designated position based on information received together with the abnormality notification. The arbitrarily designated position may be acquired by receiving an arbitrarily designated position from the terminal device 13 on which the first or second notification image is displayed. Alternatively, the arbitrarily designated position may be acquired by searching based on a direction in the moving body 12 transmitted from the terminal device 13 on which the third notification image is displayed, the position of the terminal device 13 in the moving body 12, and the positions of other terminal devices 13 in the moving body 12. After acquisition, the process proceeds to step S203.

[0070] In step S203, the control unit 27 transmits a command to capture an image of the position acquired in step S201 or step S202 to the imaging unit 18 via the communication device 15. After transmission, the abnormality handling process ends.

[0071] The control device 10 of this embodiment configured as described above assigns first identification information to the passenger's terminal device 13 when the passenger boards the moving body 12, and in response to an abnormality notification from the terminal device 13 to which the first identification information has been assigned, causes an imaging device installed in the moving body 12 to acquire an image of an arbitrary position inside the moving body 12 specified by the terminal device 13. With this configuration, the control device 10 grasps the abnormality notification and the arbitrary position from the terminal device 13 carried by the passenger who specifically determines that an abnormality has occurred, and can acquire an image focusing on an area with a high need for monitoring.

[0072] Moreover, the control device 10 further includes a storage unit 29 that stores the first identification information assigned to the terminal device 13, and the control unit 27 deletes the first identification information assigned to the passenger's terminal device 13 from the storage unit 29 when the passenger leaves the moving body 12. With this configuration, the control device 10 can recognize the passenger on board via the terminal device 13. Therefore, even if the control device 10 receives information from the passenger's terminal device 13 located near the outside of the moving body 12, the control device 10 can determine that the information is unnecessary information.

[0073] The above describes an embodiment of the control device 10. However, the embodiment of the present disclosure can also be implemented as a method or program for implementing the device, or as a storage medium on which a program is recorded (for example, an optical disk, a magneto-optical disk, a CD-ROM, a CD-R, a CD-RW, a magnetic tape, a hard disk, or a memory card, etc.).

[0074] The form of implementation of the program is not limited to application programs such as object code compiled by a compiler or program code executed by an interpreter, but may be a program module incorporated into an operating system, etc. Furthermore, the program may or may not be configured so that all processing is performed only by the CPU on the control board. The program may be configured so that a part or all of it is executed by another processing unit mounted on an expansion board or expansion unit added to the board as necessary.
