Description

[Technical field]

[0001] The present invention relates to a data processing system and a data processing method. [Background technology]

[0002] Traditionally, cameras have been installed as a measure against criminal acts (such as violence, molestation, damage to property, intimidation, and assault) that occur within stations and train carriages. For example, Patent No. 7045532 (Patent Document 1) states that "The station platform monitoring system (50) comprises an on-board station device (20) that transmits control information for determining the image layout of the surveillance camera images to be displayed on a monitor device (25) in the driver's cab mounted on a train (30), and a surveillance camera image transmission device (10) that determines the image layout based on the control information, generates surveillance camera images using images acquired from one or more surveillance cameras (16) installed on the station platform (17) based on the image layout, and transmits the surveillance camera images to the on-board station device (20)."

[0003] [Patent Document 1] Patent No. 7045532 Summary of the Invention [Problem to be solved by the invention]

[0004] According to the above conventional technology, it is possible to monitor station platforms, but it is not expected to respond to criminal acts occurring in passenger cars of trains. If a camera that captures the inside of a passenger car is installed on a train, it is expected to have a certain degree of deterrent effect against criminal acts, and if a criminal act can be captured, it can be used as evidence. However, if a criminal act occurs in a crowded passenger car, it is difficult for the camera installed on the train to clearly capture the criminal act. Passengers often carry terminals such as smartphones, and it is possible that the passenger's terminal may report the occurrence of a criminal act or provide a video of the criminal act. On the other hand, the information from the passenger's terminal is easily processed or the location or time may be falsified, so the reliability is insufficient. For this reason, there is a risk that false accusations or perjury may occur due to false or erroneous information provided, which may hinder the confirmation of facts. For these reasons, it has become an issue to collect reliable information on crimes and other crimes that occur in passenger cars. This issue is not limited to train passenger compartments, but also applies to passenger compartments of buses, ships, airplanes, and other moving vehicles that transport passengers. [Means for solving the problem]

[0005] In order to solve the above problems, one representative data processing system of the present invention comprises a signal transmitter installed in a mobile body and transmitting a device-specific signal to the surrounding area, an information providing processing device that communicates with a passenger communication terminal carried by a passenger of the mobile body and receives information provided from the passenger communication terminal regarding a problem that has occurred in the passenger compartment of the mobile body, and a recording device that records the information provided from the passenger communication terminal, and is characterized in that, on condition that the passenger communication terminal has received the device-specific signal from the signal transmitter, the information providing processing device certifies that the information provided from the passenger communication terminal is information regarding a problem that has occurred in the passenger compartment of the mobile body. In addition, one representative data processing method of the present invention is characterized by including a step of a signal transmitter installed in a mobile body transmitting a device-specific signal to the surrounding area, a step of an information providing processing device communicating with a passenger communication terminal carried by a passenger of the mobile body and receiving information from the passenger communication terminal regarding a problem that has occurred in the passenger compartment of the mobile body, a step of the information providing processing device authenticating that the information provided from the passenger communication terminal is information regarding a problem that has occurred in the passenger compartment of the mobile body, on condition that the passenger communication terminal has received the device-specific signal from the signal transmitter, and a step of a recording device recording the information provided from the passenger communication terminal. Effect of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Note that the embodiments described below do not limit the invention according to the claims, and all of the elements and combinations thereof described in the embodiments are not necessarily essential to the solution of the invention. EXAMPLES

[0009] FIG. 1 is a diagram showing a system configuration of a data processing system according to an embodiment of the present disclosure. The data processing system includes on-board systems, station systems, and wayside systems. On-board systems are systems installed on the train itself. Station systems are systems that include equipment installed in stations. Wayside systems are systems that include equipment related to train operation that is installed outside of trains and stations, such as control centers and signals.

[0010] The on-board system can communicate with passenger communication terminals (e.g., smartphones) 1. The data processing system has an on-board wired network in which the conductor's business terminal (e.g., tablet) 2, a wireless LAN access point 3 installed in each car, an on-board camera 6 installed as a security camera, a recording device 5 that records images captured by the passenger communication terminals 1, an on-board camera 6 installed as a forward camera, a GPS device 8, a network termination device 9 of a dedicated line wireless network 11, and an on-board control device 7 are connected by an Ethernet switch 4 installed between each car.

[0011] The network termination device of the ground system is connectable to the passenger communication terminal 1 via a public wireless network 10 . In addition, the network termination device 9 of the on-board system, the network termination device of the ground system, and the network termination device of the station system can be connected via a dedicated line wireless network 11.

[0012] The ground system includes a ground system network that connects an alert / video processing device 13 connected to a recording device 12, an operation management information device 14, and an application downloader 22 that provides applications (hereinafter referred to as apps) to passenger communication terminals via an Ethernet switch. The station system includes a station system network in which a station camera control device 16, an alert / image processing device 15, and a recording device 20 that records images from a station camera 21 are connected by an Ethernet switch 19.

[0013] The public wireless network 10 may take any form as long as it is a network that connects passenger communication terminals to a ground system. The dedicated line wireless network 11 may be, for example, a network used by a railway company for communication between the ground and on-board trains, and may be a general-purpose network.

[0014] The access point 3 of the on-board system is not limited to a wireless LAN access point or the like, as long as the passenger communication terminal 1 or the business terminal 2 can be connected to the on-board network.

[0015] Figure 2 is a block diagram showing common parts of the hardware configuration of each device (passenger communication terminal 1, business terminal 2, on-board control device 7, alert / video processing device 13, operation management information device 14, alert / video processing device 15, station camera control device 16, and application downloader 22).

[0016] Each device includes a CPU (Central Processing Unit) 1-01, a memory 1-02, a communication NIC (Network Interface Card) 1-03, a HDD (Hard Disk Drive) 1-04, an input / output controller 1-05, and a monitor controller 1-06.

[0017] In some of the devices, the input / output controller 1-05 is connected to a keyboard 1-11 and a mouse 1-12. In some of the devices, the monitor controller 1-06 is connected to a display 1-13. In some of the devices, a touch panel (not shown) is provided instead of the keyboard 1-11, the mouse 1-12, and the display 1-13 in the above configuration. It is not necessary that all of these devices are provided. Furthermore, in addition to the above configuration, the passenger communication terminal 1, the business terminal 2, and the on-board control device 7 are provided with a GPS module 1-08 or an interface therefor as a position acquisition unit that acquires position information.

[0018] The CPU1-01 is hardware (processor) that controls each device, and performs various processes by reading a program from the memory 1-02 and executing the read program. The memory 1-02 temporarily stores a program that defines the operation of the CPU1-01 and control data used in the processing of the CPU1-01. The communication NIC1-03 is a device that communicates with other devices via a network, and some have two or more NICs for wireless and wired communication. The HDD1-04 stores a program that defines the operation of the CPU1-01. Instead of the HDD1-04, an SSD (Solid State Drive) or the like may be provided.

[0019] It is assumed that the emergency button application 1-A or the on-board camera application 1-B shown in Fig. 3(a) is installed in advance in the passenger communication terminal 1. When installing the application, the application downloader 22 in Fig. 1 may require the application user to register the name, telephone number, and SNS account name when downloading the application. This is to enable the application user to authenticate that they have used the application.

[0020] Alternatively, if users want to keep their personal information private, they can set up their own account. By keeping personal information private, we hope to lower the resistance to using emergency button apps and in-car camera apps, and promote the use of this app.

[0021] Also, the emergency button application 1-A and the on-board camera application 1-B may be set to start only when the signal included in the beacon signal of the access point 3 in Fig. 1 matches the signal provided by the railway company that provides this system. This is to authenticate that the passenger communication terminal 1 is being used on the train.

[0022] Furthermore, the images captured by the on-board camera application 1-B are not retained inside the passenger communication terminal 1, but are directly stored in the recording device 5 of the on-board system or the recording device 12 of the ground system. This is to prevent the images from being subsequently processed or leaked to external sites.

[0023] FIG. 5 is a diagram showing the sequence until the ground system and on-board system verify that an alert issued from an emergency button app on a passenger communication terminal was issued by a passenger on a moving vehicle.

[0024] The on-board beacon signal detection unit (1-v in Fig. 10) of the passenger communication terminal 1 (e.g., a smartphone) of the passenger on board the train constantly receives beacon signals from the surrounding access points 3, and recognizes the ID of the strongest signal as the nearest access point (1-1). Note that the wireless LAN access point 3 continues to transmit a beacon signal specific to the device that has been set in advance, using an SSID or other means.

[0025] When a passenger is a victim of or witnesses a sexual assault or other crime and presses the emergency button icon (Fig. 3 1-A) on the emergency button app (Fig. 10 1-i) (1-2), a message including the beacon signal ID (e.g., SSID) is sent from the ground system communications processing unit (Fig. 10 1-ii). When this message arrives at the token generation / matching unit (13-i in Fig. 14) of the ground system's alert / video processing device 13, a token is generated and sent back to the ground system communication processing unit (1-ii in Fig. 10) of the passenger communication terminal 1 (13-1).

[0026] When the passenger communication terminal 1 receives the token, it transfers it (1-4) to the token confirmation unit (Fig. 13 7-i) of the on-board control device 7. The token confirmation unit (Fig. 13 7-i) of the on-board control device 7 acquires the GPS information at the time of receiving the token from the GPS interface (Fig. 13 7-ii) and transfers it together with the token to the alert / image processing device 13 (7-1).

[0027] The traffic management information collation unit (13-ii in FIG. 14) of the alert / image processing device 13 inquires of the traffic management information device 14 whether the GPS information is consistent with the vehicle traffic management schedule (13-2). When the traffic management information device 14 confirms the consistency, it responds to that effect to the alert / image processing device 13 (14-1).

[0028] The token generating unit / verifying unit (13-i in Fig. 14) of the alert / video processing device 13 officially approves (13-3) the pressing of the alert button icon on the passenger communication terminal 1. A message indicating approval is received by the ground system communication processing unit (1-ii in Fig. 10) of the passenger communication terminal 1 and displayed on the screen (1-iii in Fig. 10) (1-5). The message is also received by the on-board control device 7, and in the alert authentication process (7-iii), it is broadcast (7-2) to all devices on the on-board network. The broadcasted message is received by the business terminal 2 (2-1), and the message (Fig. 4 2-A) and an image showing the location of the incident (Fig. 4 2-B, 2-C) are displayed on the business terminal screen in the video display section (Fig. 11 2-i).

[0029] FIG. 6 is a sequence diagram showing a process of handling a video captured by the on-board camera application of the passenger communication terminal 1. The process up to the point where the ground system and on-board system confirm that an image has been taken by the passenger communication terminal 1 of a passenger on a moving vehicle is the same as that shown in FIG. 5, and therefore will not be described. When a passenger is a victim of or witnesses molestation or violence and presses the on-board camera icon (Figure 3 1-B) on the on-board camera app (Figure 10 1-iv), the video is transferred to the video display unit of the business terminal 2 (Figure 11 2-i).

[0030] The transferred images and location information are displayed on the screen of the business terminal 2 by the camera of the passenger communication terminal 1 (Fig. 4 2-D, 2-B) (1-8). Moreover, this video and the shooting position are transferred to the alarm / video recording section (FIG. 12 5-i) of the recording device 5 and stored in the storage (FIG. 12 5-ii). Furthermore, vehicle position information is obtained from the GPS interface of the on-board control device 7 (Fig. 13 7-ii), and the passenger camera video quality change instruction unit (Fig. 13 7-iv) filters the video so as not to overload the bandwidth of the dedicated wireless network 11, and the video is then transferred to the alert / video processing device 13 of the ground system (7-5).

[0031] Thereafter, as in FIG. 5, an inquiry (13-7) of vehicle position information is made with the traffic management information device 14, and a comparison (14-4) of on-vehicle position information is made, and the live video is stored (13-8) in the recording device 12 of the ground system from the alert or video recording unit (13-iii) of the alert / video processing device 13. Furthermore, the train's next stop station is obtained from the operation control information collation unit (13-ii in Fig. 14) of the alert / video processing device 13 in the ground system, and live video information is transferred from the alert or video transfer unit (13-iv in Fig. 14) to the alert / video processing device 15 at the stop station (13-9). The process shown in FIG. 6 continues until the passengers using the passenger communication terminals 1 finish capturing live video.

[0032] FIG. 7 is a sequence diagram showing a process in which a plurality of on-board cameras 6 cooperate with each other to improve the quality of an image showing a suspect. The on-board camera image quality change instruction unit (Fig. 13 7-v) of the on-board control device 7, which has received the live video and Wifi signal strength from the passenger communication terminal 1 at 7-5 in Fig. 6, estimates the car in which the passenger using the passenger communication terminal 1 is located from the Wifi strength signal. Here, car number 1 is taken as an example of the estimated result. The on-board camera image quality change instruction unit issues an instruction to change (improve) the camera quality to the on-board camera of car number 1 (on-board camera @ car 1), which is the estimated result. The instruction is given by changing the transfer rate, frame size, or bit rate. The instruction varies depending on the type of camera installed (6-1).

[0033] This video is received by the video authentication / quality processing unit (7-vi in ​​Fig. 13) of the on-board control device 7, and then the video quality is reduced so as not to place a load on the dedicated line wireless network 11, after which it is received by the alert or video recording unit (13-iii in Fig. 14) of the alert / video processing device 13 in the ground system and stored in the recording device 12. For video quality control that does not place a load on the dedicated line wireless network 11, communication middleware implementing protocols such as RTSP and SRT may be used.

[0034] This video is also stored in the storage (FIG. 12, 5-ii) via the alarm / video recording section (FIG. 12, 5-i) of the on-board recording device 5. Furthermore, this image is also received by the emergency button / on-board camera image detection unit (Figure 11 2-i) of the business terminal 2, and a message indicating that the image is being transferred (Figure 4 2-A) and live image (Figure 4 2-D) are displayed.

[0035] The suspect tracking processing unit (7-vii in FIG. 13) of the on-board control device 7 detects the suspect's movement direction and estimates the vehicle to which the suspect is moving (7-8). Any existing technology may be used to detect the suspect's movement direction using multiple cameras. The suspect may be identified by, for example, the conductor using the image captured on the business terminal 2 to give instructions to the on-board control device 7.

[0036] When the on-board control device 7 detects that the suspect is leaving vehicle No. 1 and heading toward another vehicle (here, vehicle No. 2), it instructs the on-board camera in vehicle No. 2 to change (improve) the camera image quality (6-2). In this way, it is possible to improve the image quality of the suspect's destination in advance. If the suspect is identified in car No. 2, the on-board control device issues a command (6-3) to the on-board camera in car No. 1 to change (reset) the camera image quality.

[0037] FIG. 8 is a sequence diagram showing a process for improving the quality of images of a suspect by using a train-mounted camera and a station camera in cooperation with each other. The suspect tracking processing unit (Fig. 13 7-vii) of the on-board control device 7 uses the location information obtained from the GPS interface (Fig. 13 7-ii) to confirm that the vehicle has stopped at the station (7-11) and that the suspect has disembarked (7-12), and then passes the suspect information to the suspect tracking processing unit (Fig. 15 16-i) of the station camera control device 16 via the dedicated wireless network 11, and then issues an instruction to the on-board camera 6 in car No. 2 to change (reset) the camera image quality (6-5).

[0038] The suspect tracking processing unit (16-i in Fig. 15) of the station camera control device 16 starts tracking the suspect's image (16-1), and the camera image quality change instruction unit (16-ii) issues an instruction to change (improve) the camera image quality to the east station camera 21 that is recognized to be recording the suspect (21-1). The image information is stored in the storage (16-iii in Fig. 15).

[0039] When the suspect tracking processing unit (16-i in FIG. 15) of the station camera control device 16 detects the direction in which the suspect is moving (16-2), it issues an instruction (21-2) to change (improve) the camera image quality of another station camera (the camera on the west side) located in the detected direction.

[0040] The camera image quality change instruction unit (16-ii in FIG. 15) of the station camera control device 16 issues an instruction (21-3) to change (reset) the camera image quality after confirming that the suspect is not captured by the east-side camera.

[0041] FIG. 9 is a sequence diagram showing a continuation of the sequence of FIG. When the suspect tracking processing unit (16-i in Fig. 15) of the station camera control device 16 detects the suspect's movement direction (16-3) and determines that the suspect has boarded a vehicle parked at the station, it sends the suspect information (16-3) to the suspect tracking processing unit (7-vii in Fig. 13) of the on-board control device 7 of the vehicle parked at the station via the dedicated wireless network 11. After receiving the information, the suspect tracking processing unit of the on-board control device 7 detects the suspect's movement direction (7-14) and issues an instruction (6-7) to the on-board camera of the vehicle in which the suspect is riding to change (improve) the camera image quality.

[0042] FIG. 3 shows the display of the passenger communication terminal, and FIG. 4 shows the display of the business terminal. The processing sequence has already been explained in FIG. 5 and FIG. 6, so it will not be repeated here. When the emergency button icon (Fig. 3 1-A) of the emergency button app (Fig. 10 1-i) is pressed on the display of the passenger communication terminal 1 (Fig. 5 1-2), a chat screen for chatting with the conductor's business terminal becomes active (Fig. 3(b), Fig. 4 2-F).

[0043] Passengers or conductors can chat using the message input field (Figure 3(b) 1-E, Figure 4 2-F3) and output field (Figure 3(b) 1-C, Figure 4 2-F1) on this chat screen, and if they are unable to input text, they can select and send a registered message (Figure 3 1-D, Figure 4 2-F2).

[0044] For example, messages registered on a passenger communication terminal might include "This is a molester," "This is violence," or "This is a fire," while on a business terminal, messages might include "We will come to the rescue" or "A message will be sent on board." These processes can also be notified by voice. These functions are performed by the chat / voice communication processing unit (1-vi) of the passenger communication terminal 1 and the chat / voice communication processing unit (2-iii) of the business terminal 2 in cooperation with each other. In addition, by operating the scroll bar (Fig. 4 2-E) of the business terminal 2 left and right, this information is transferred to the recording device playback processing unit (Fig. 11 2-iv) of the passenger communication terminal 1, and the recording and playback processing unit (Fig. 12 5-iii) of the recording device 5 rewinds, fast-forwards, and plays the video stored in the storage (Fig. 12 5-ii).

[0045] FIG. 16 is a diagram showing a sequence in which an alert signal of a passenger communication terminal is authenticated in the system of the present invention without using the on-board control device 7. The processing sequences of FIG. 16 and FIG. 5 differ in that location information acquired by the passenger communication terminal is used. The on-board beacon signal detection unit (1-v in Fig. 10) of the passenger communication terminal 1 (e.g., a smartphone) of the passenger on board the train constantly receives beacon signals from the surrounding access points 3, and recognizes the ID of the strongest signal as the nearest access point (1-31). Note that the wireless LAN access point 3 is assumed to continuously transmit a beacon signal specific to the device that has been set in advance, using an SSID or other means.

[0046] When a passenger is a victim of or witnesses a sexual assault or other crime and presses (1-32) the emergency button icon (Fig. 3 1-A) on the emergency button app (Fig. 10 1-i), a message including the beacon signal ID (e.g., SSID) is sent from the ground system communications processing unit (Fig. 10 1-ii).

[0047] When this message arrives at the token generation / matching unit (13-i in Fig. 14) of the ground system's alert / video processing device 13, a token is generated and sent back to the ground system communication processing unit (1-ii in Fig. 10) of the passenger communication terminal 1 (13-31).

[0048] When the passenger communication terminal 1 receives the token, it acquires the current location information obtained from the GPS module or other means in the current location information acquisition unit (FIG. 10 1-vii) and transfers it together with the token to the alert / video processing device 13 (1-33). The traffic management information collation unit (13-ii in FIG. 14) of the alert / image processing device 13 inquires of the traffic management information device 14 whether the GPS information is consistent with the vehicle traffic management schedule (13-2). When the traffic management information device 14 confirms the consistency, it responds to that effect to the alert / image processing device 13 (14-1).

[0049] The token generating unit / verifying unit (13-i in Fig. 14) of the alert / video processing device 13 officially approves (13-33) the pressing of the alert button icon on the passenger communication terminal 1. A message indicating approval is received by the ground system communication processing unit (1-ii in Fig. 10) of the passenger communication terminal 1 and displayed on the screen (1-iii in Fig. 10). The message is also received by the business terminal 2 (2-1), and the video display unit (Fig. 11 2-i) displays the message (Fig. 4 2-A) and video showing the location where the message occurred (Figs. 4 2-B, 2-C) on the business terminal screen.

[0050] FIG. 17 is a diagram showing a sequence in which an image captured by a passenger communication terminal without using the on-board control device 7 is authenticated in the system of the present invention. The processing sequence of FIG. 17 differs from that of FIG. 6 in that the captured video is sent from the passenger communication terminal. The process up to the point where the ground system and on-board system verify that an image has been taken by the passenger communication terminal 1 of a passenger on a moving vehicle is the same as that shown in FIG. 16, and therefore will not be described. When a passenger is a victim of or witnesses molestation or violence and presses the on-board camera icon (Figure 3 1-B) on the on-board camera app (Figure 10 1-iv), the video is transferred to the video display unit of the business terminal 2 (Figure 11 2-i). The transferred image and location information are displayed on the screen of the business terminal 2 by the camera of the passenger communication terminal 1 (Fig. 4 2-D, 2-B) (1-38). Moreover, this video and the shooting position are transferred to the alarm / video recording section (FIG. 12 5-i) of the recording device 5 and stored in the storage (FIG. 12 5-ii). Furthermore, vehicle location information is acquired from the current location information acquisition unit (Fig. 10 1-vii) of the passenger communication terminal 1, and the on-board control device communication processing unit (Fig. 10 1-iii) filters the video so as not to overload the bandwidth of the public wireless network 10, and transfers it to the alert / video processing device 13 of the ground system (1-38).

[0051] Thereafter, as in FIG. 16, an inquiry (13-37) of vehicle position information is made with the traffic management information device 14, and a comparison (14-34) of on-vehicle position information is made, and the live video is stored (13-38) in the recording device 12 of the ground system from the alert or video recording unit (13-iii) of the alert / video processing device 13.

[0052] Furthermore, the train's next stop station is obtained from the operation control information collation unit (13-ii in Fig. 14) of the alert / video processing device 13 in the ground system, and live video information is transferred from the alert or video transfer unit (13-iv in Fig. 14) to the alert / video processing device 15 at the stop station (13-39). The process shown in FIG. 17 continues until the passengers using the passenger communication terminals 1 finish capturing live video.

[0053] As described above, the disclosed data processing system comprises a signal transmitter (access point 3) installed in a mobile body and transmitting a device-specific signal to the surrounding area, an information providing processing device (alert / video processing device 13) that communicates with a passenger communication terminal 1 carried by a passenger of the mobile body and receives information provided from the passenger communication terminal 1 regarding a problem that has occurred in the passenger cabin of the mobile body, and a recording device (recording device 5, recording device 20) that records the information provided from the passenger communication terminal, and, provided that the passenger communication terminal receives the device-specific signal from the signal transmitter, the information providing processing device certifies that the information provided from the passenger communication terminal is information regarding a problem that has occurred in the passenger cabin of the mobile body. This makes it possible to collect highly reliable information about crimes that occur on board passenger cars.

[0054] In addition, the signal transmitter is an access point for wireless communication, and the signal transmitter is provided in each of a plurality of passenger rooms of the mobile body, the signal transmitter transmits identification information used for the wireless communication to the surrounding area as a signal unique to the device, and the passenger communication terminal is capable of wireless communication with the information provision processing device via the signal transmitter. According to this configuration and operation, the passenger communication terminal 1 detects the identification information of the access point 3 installed in each passenger compartment, and based on communication with the information provision processing device via the access point 3, it can be confirmed that the passenger communication terminal 1 is actually present in the mobile body and has provided information.

[0055] The information received by the information providing processing device is a report of the occurrence of the problem and / or a video image taken about the problem. This makes it possible to collect and record alerts from victims and witnesses of crimes and the like, and footage taken by victims and witnesses of crimes and the like, with a high degree of reliability.

[0056] The system further includes a location information acquisition device installed on the mobile body and acquiring location information of the mobile body, wherein the information providing processing device receives a token sending request from the passenger communication terminal and sends a token to the passenger communication terminal, the passenger communication terminal transfers the token to the location information acquisition device, the location information acquisition device assigns location information to the token and returns it to the information providing processing device, and the information providing processing device authenticates the provided information on the condition that the location information assigned to the token is consistent with operation information of the mobile body. In this way, by obtaining information about the movement of mobile objects and checking its consistency, the reliability of the provided information can be more highly evaluated.

[0057] The recording device also records information provided in real time from the passenger communication terminal. Therefore, the time information of the provided information can also be managed on the recording device side, thereby ensuring its reliability.

[0058] The vehicle further includes an imaging device (on-board camera 6) that is installed on the vehicle and captures images of the passenger compartment, and when authentication is performed by the information processing device, the signal transmitter is identified from a signal unique to the device used for the authentication, and the image capture result of the passenger compartment corresponding to the identified signal transmitter is recorded in the recording device as an image capture result related to the problem. This will enable the information provided by passengers to be matched with the images captured by the on-board camera, making it possible to collect a wider range of information on criminal activity, etc.

[0059] In other words, the disclosed system proves that the time and location of the alerts from passenger communication devices and the captured images match the time and location of the moving vehicle, and can be secured as evidence. As a result, it becomes possible to grasp the occurrence of an incident in real time, and to protect victims and secure the custody of suspects at the train's arrival station. Examples of what the disclosed system can do include the following: (1) Allowing victim passengers to use their smartphones to issue alerts, which can then be verified as coming from the train, with the time and place of the alert identified, and the alert verified as coming from the train, with a third party other than the victim (e.g., the railroad company) verifying that the alert was indeed sent from the train. (2) A passenger who witnesses a crime can take a video of the crime using his or her smartphone, identify the time and place where the video was taken, and verify that the video was taken on board the train. A third party other than the witness (e.g., the railway company) can verify that the video was definitely taken on board the train. (3) It is possible to identify the passenger’s position on the train (e.g., the train number) and the shooting angle, and to verify that the video was shot from a specific position on the train. It is possible to verify that the video was definitely shot from a specific position on the train. (4) The on-board system that detects the alert estimates the location of the incident based on the above authentication, records high-resolution video using an on-board camera installed near the location of the incident, and authenticates the identity of the vehicle in which the victim is located. (5) If a suspect is suspected to be moving around in a vehicle, the settings of the camera in the vehicle to which the suspect is moving will be changed in advance (high resolution, high rate) and the camera will wait for the suspect to move around in order to obtain footage with high evidentiary value. (6) All or part of the footage of the incident will be transmitted in advance to the ground system, the next arrival station of the train, and the terminal of the station attendant, in order to contribute to communication with the victim of the incident and the person who filmed it, to the protection of the victim, and to the arrest of the suspect. (7) The on-board cameras will be linked to the station cameras in the ground system, making it possible to continue tracking suspects using the station cameras.
