Description

Data processing system and data processing method

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

[0002] Conventionally, cameras have been installed as a measure against criminal acts (such as violence, molestation, vandalism, intimidation, and assault) occurring within train premises or in passenger cars of trains. For example, Japanese Patent No. 7045532 (Patent Document 1) states that "a station platform monitoring system (50) includes an on-board station device (20) that transmits control information for determining the video layout of surveillance camera images 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 video 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 video layout, and transmits the surveillance camera images to the on-board station device (20)."

[0003] Patent No. 7045532

[0004] While the above-mentioned conventional technology allows for monitoring station platforms, it is not designed to address criminal acts occurring within train passenger cars. Installing cameras capable of capturing images inside passenger cars on trains can be expected to have a certain degree of deterrent effect against criminal acts, and capturing images of criminal acts can be used as evidence. However, if a criminal act occurs inside a crowded passenger car, it is difficult for the cameras installed on the train to clearly capture the criminal act. Passengers often carry devices such as smartphones, and it is conceivable that passengers may report the occurrence of a criminal act or provide footage of the criminal act using their devices. However, information from passenger devices is easily manipulated or falsified in terms of location and time, making it unreliable. Therefore, false or erroneous information may lead to false accusations or perjury, which may actually hinder the verification of facts. For these reasons, collecting reliable information about criminal acts occurring within passenger cars is a challenge. This challenge is not limited to train passenger compartments, but also applies to passenger compartments of vehicles that transport passengers, such as buses, ships, and airplanes.

[0005] In order to solve the above problem, one representative data processing system of the present invention comprises a signal transmitter installed in a mobile body that transmits 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 by 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, wherein 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, provided that the passenger communication terminal has received the device-specific signal from the signal transmitter. Furthermore, one representative data processing method of the present invention is characterized by including the steps of: a signal transmitter installed in a mobile body transmitting a device-specific signal to the surrounding area; an information provision 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 provision 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, provided that the passenger communication terminal has received the device-specific signal from the signal transmitter; and a recording device recording the information provided from the passenger communication terminal.

[0006] According to the present invention, highly reliable information can be collected about criminal acts that occur in passenger cars. Problems, configurations, and effects other than those described above will become clear from the following description of the 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 not all of the elements and combinations thereof described in the embodiments are necessarily essential to the solution of the invention.

[0009] 1 is a diagram illustrating a system configuration of a data processing system according to an embodiment of the present disclosure. The data processing system includes an on-board system, a station system, and a wayside system. The on-board system is a system installed on the train itself. The station system is a system including equipment installed in stations. The wayside system is a system including equipment related to train operation, such as a control center and signals, that is installed outside of trains and stations.

[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, wireless LAN access points 3 installed in each car, on-board cameras 6 installed as security cameras, recording devices 5 that record images captured by the passenger communication terminals 1, on-board cameras 6 installed as forward cameras, GPS devices 8, network termination devices 9 of the dedicated wireless network 11, and on-board control devices 7 are connected by Ethernet switches 4 installed between each car.

[0011] The network termination device of the ground system can be connected to the passenger communication terminal 1 via a public wireless network 10. Furthermore, 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 wireless network 11.

[0012] The ground system has a ground system network in which an alert / video processing device 13 connected to a recording device 12, an operation control information device 14, and an application downloader 22 that provides applications (hereinafter abbreviated as apps) to passenger communication terminals are connected by an Ethernet switch. The station system has a station system network in which a station camera control device 16, an alert / video 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 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, or 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 the 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 has 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 addition, 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. Note that not all of these devices are necessarily 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 its interface as a position acquisition unit that acquires position information.

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

[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 on the passenger communication terminal 1. When installing the application, the application downloader 22 in Fig. 1 may require the application user to register their name, phone 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, users will feel more comfortable using emergency button apps and in-car camera apps, and this will promote the use of this app.

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

[0022] Furthermore, the images captured by the on-board camera application 1-B are not stored 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 wayside system, in order to prevent the images from being subsequently edited or leaked to external sites.

[0023] FIG. 5 is a diagram showing the sequence until the ground system and on-board system recognize that an alert issued from the emergency button app on the 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 a passenger on a train continuously 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 continuously transmits a beacon signal specific to the device that has been set in advance using an SSID or other means.

[0025] When a passenger is the victim of or witnesses a molestation or assault and presses the emergency button icon (Fig. 3 1-A) on the emergency button app (Fig. 10 1-i) (1-2), a message accompanied by the ID (e.g., SSID) of the beacon signal is issued from the ground system communication processing unit (Fig. 10 1-ii). When this message arrives at the token generation unit / verification unit (Fig. 14 13-i) of the alert / video processing device 13 in the ground system, a token is generated and sent back to the ground system communication processing unit (Fig. 10 1-ii) 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 (7-i in Fig. 13) of the on-board control device 7. The token confirmation unit (7-i in Fig. 13) of the on-board control device 7 acquires the GPS information at the time of receiving the token from the GPS interface (7-ii in Fig. 13) and transfers it together with the token to the alert / video processing device 13 (7-1).

[0027] The traffic management information collating unit (13-ii in FIG. 14) of the alert / video 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 / video processing device 13 (14-1).

[0028] The token generator / verifier (13-i, Fig. 14) of the alert / video processing device 13 officially certifies the pressing of the alert button icon on the passenger communication terminal 1 (13-3). A message indicating the authorization is received by the wayside system communication processor (1-ii, Fig. 10) of the passenger communication terminal 1 and displayed on the screen (1-iii, 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 to all devices on the on-board network (7-2). The broadcast message is received by the operations terminal 2 (2-1), and the video display unit (2-i, Fig. 11) displays the message (2-A, Fig. 4) and videos showing the location of the incident (2-B, 2-C, Fig. 4) on the operations terminal screen.

[0029] Fig. 6 is a sequence diagram showing the process of handling video captured by the on-board camera app of the passenger communication terminal 1. The process up to the point where the track system and on-board system confirm that the video was captured by the passenger communication terminal 1 of a passenger on a moving train is the same as the process in Fig. 5, and therefore will not be described here. When a passenger is the victim of or witnesses a sexual assault or other crime and presses the on-board camera icon (Fig. 3 1-B) on the on-board camera app (Fig. 10 1-iv), the video is transferred to the video display unit (Fig. 11 2-i) of the operations terminal 2.

[0030] The transferred video 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). The video and the shooting location are also transferred to the alarm / video recording unit (Fig. 12, 5-i) of the recording device 5 and stored in storage (Fig. 12, 5-ii). Furthermore, vehicle location information is obtained from the GPS interface (Fig. 13, 7-ii) of the on-board control device 7, and the video is filtered by the passenger camera video quality change instruction unit (Fig. 13, 7-iv) so as not to overload the bandwidth of the dedicated wireless network 11, and then transferred to the alert / video processing device 13 of the ground system (7-5).

[0031] 5, vehicle position information is queried (13-7) and on-board position information is verified (14-4) with the traffic management information device 14, and live video is stored in the recording device 12 of the track system from the alert or video recording unit (13-iii) of the alert / video processing device 13 (13-8). Furthermore, the next stop of the vehicle is obtained from the traffic management information verification unit (13-ii) of the alert / video processing device 13 of the track system, and live video information is transferred from the alert or video transfer unit (13-iv) of FIG. 14 to the alert / video processing device 15 of the stop station (13-9). The process shown in FIG. 6 continues until the passenger at the passenger communication terminal 1 finishes recording the live video.

[0032] FIG. 7 is a sequence diagram showing the process of improving the quality of video of a suspect by linking multiple on-board cameras 6. At 7-5 in FIG. 6, the on-board camera video quality change instruction unit (FIG. 13 7-v) of the on-board control device 7 receives live video and Wi-Fi signal strength from the passenger communication terminal 1 and estimates the vehicle in which the passenger using the passenger communication terminal 1 is located based on the Wi-Fi signal strength. Here, car No. 1 is used as an example of the estimated result. The on-board camera video quality change instruction unit issues a camera quality change (improvement) instruction to the on-board camera of car No. 1 (on-board camera @ car 1), which is the estimated result. The instruction is issued by changing the transfer rate, frame size, and bit rate. The content of this 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 wireless network 11. After that, it is received by the alert or video recording unit (13-iii in Fig. 14) of the alert / video processing device 13 of the track system and stored in the recording device 12. For video quality control that does not place a load on the dedicated wireless network 11, communication middleware that implements protocols such as RTSP and SRT may be used.

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

[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 can be used to detect the suspect's movement direction using multiple cameras. For example, the conductor may issue instructions to the on-board control device 7 using the video captured on the business terminal 2 to identify the suspect.

[0036] When the on-board control device 7 detects that the suspect is leaving car No. 1 and heading toward another car (car No. 2 in this example), it instructs the on-board camera in car 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. When the suspect is spotted in car No. 2, the on-board control device instructs the on-board camera in car No. 1 to change (reset) the camera image quality (6-3).

[0037] 8 is a sequence diagram showing the process of improving the quality of the video of a suspect by linking the on-board camera and the station camera. When the suspect tracking processor (FIG. 13 7-vii) of the on-board control device 7 confirms (7-11) that the train has stopped at the station and (7-12) that the suspect has disembarked, using the location information obtained from the GPS interface (FIG. 13 7-ii), it passes the suspect information to the suspect tracking processor (FIG. 15 16-i) of the station camera control device 16 via the dedicated wireless network 11, and then issues a command to the on-board camera 6 in car 2 to change (reset) the camera video 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 video (16-1), and the camera video quality change instruction unit (16-ii) issues an instruction to change (improve) the camera video quality to the east station camera 21 that is recognized as capturing the suspect (21-1). The video information is stored in the storage (16-iii in Fig. 15).

[0039] When the suspect tracking processing unit (16-i in Figure 15) of the station camera control device 16 detects the direction of movement of the suspect (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 a camera image quality change (reset) instruction (21-3) after confirming that the suspect is not visible on the east side camera.

[0041] Figure 9 is a sequence diagram showing a continuation of the sequence in Figure 8. When the suspect tracking processing unit (16-i) of the station camera control device 16 detects the suspect's movement direction (16-3) and determines that the suspect has boarded a vehicle stopped at a station, it sends the suspect information (16-3) to the suspect tracking processing unit (7-vii) of the on-board control device 7 of the vehicle stopped 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 change (improve) the camera image quality to the on-board camera of the vehicle in which the suspect is riding.

[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 explained 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 business terminal held by the conductor becomes active (Fig. 3(b), Fig. 4 2-F).

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

[0044] The registered messages may be, for example, "This is a molester," "This is violence," or "This is a fire" for a passenger communication terminal, or "We're coming to rescue you" or "We're sending a message on board" for a business terminal. These processes can also be notified by voice. These functions are performed in cooperation with 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 addition, by operating the scroll bar (2-E) of the business terminal 2 left or right, this information is transferred to the recording device playback processing unit (2-iv) of the passenger communication terminal 1, and the recording / playback processing unit (5-iii) of the recording device 5 rewinds, fast-forwards, and plays back the video stored in the storage (5-ii) of the recording device 5.

[0045] Figure 16 is a diagram showing a sequence in which an alert signal from 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 Figure 16 and Figure 5 differ in that location information acquired by the passenger communication terminal is used. The on-board beacon signal detection unit (Figure 10 1-v) of the passenger communication terminal 1 (e.g., a smartphone) of a passenger on a train continuously receives beacon signals from 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 unique to the device, set in advance, using an SSID or other means.

[0046] When a passenger is a victim of or witnesses molestation or violence and presses (1-32) the emergency button icon (Fig. 3 1-A) on the emergency button app (Fig. 10 1-i), a message containing the beacon signal ID (e.g., SSID) is sent from the ground system communication processor (Fig. 10 1-ii).

[0047] When this message arrives at the token generation / verification unit (13-i in Fig. 14) of the alert / video processing device 13 of the ground system, 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 current location information obtained by a GPS module or other means using a current location information acquisition unit (1-vii in FIG. 10) and transfers this information together with the token to the alert / video processing device 13 (1-33). The traffic management information matching unit (13-ii in FIG. 14) of the alert / video 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). If the traffic management information device 14 confirms the consistency, it responds to that effect to the alert / video processing device 13 (14-1).

[0049] The token generation unit / verification unit (13-i in Fig. 14) of the alert / video processing device 13 officially certifies (13-33) that the alert button icon on the passenger communication terminal 1 has been pressed. A message indicating the authorization 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 operations terminal 2 (2-1), and the video display unit (2-i in Fig. 11) displays the message (2-A in Fig. 4) and video showing the location of the incident (2-B and 2-C in Fig. 4) on the operations terminal screen.

[0050] FIG. 17 shows a sequence for authenticating video captured by a passenger communication terminal in the system of the present invention without using the on-board control device 7. 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 track system and on-board system verify that the video was captured by the passenger communication terminal 1 of a moving passenger is the same as that of FIG. 16 and is therefore omitted. When a passenger is the victim of or witnesses a sexual assault or other crime and presses the on-board camera icon (FIG. 3, 1-B) in the on-board camera app (FIG. 10, 1-iv), the video is transferred to the video display unit (FIG. 11, 2-i) of the operations terminal 2. The transferred video and location information are displayed on the screen of the operations terminal 2 by the camera of the passenger communication terminal 1 (FIG. 4, 2-D, 2-B) (1-38). The video and the capture location are also transferred to the alarm / video recording unit (FIG. 12, 5-i) of the recording device 5 and stored in storage (FIG. 12, 5-ii). Furthermore, the vehicle's location information is acquired from the current location information acquisition unit (1-vii in Fig. 10) of the passenger communication terminal 1, and the on-board control device communication processing unit (1-iii in Fig. 10) filters the video so as not to overwhelm the bandwidth of the public wireless network 10, and then 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 operation management information device 14, and on-board position information is verified (14-34), and live video is stored 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 (13-38).

[0052] Furthermore, the train's next stop is acquired from the operation control information collation unit (13-ii in Fig. 14) of the alert / video processing device 13 of 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 passenger at the passenger communication terminal 1 finishes taking live video.

[0053] As described above, the disclosed data processing system includes a signal transmitter (access point 3) installed in a mobile vehicle that transmits a device-specific signal to the surrounding area, an information provision processing device (alert / video processing device 13) that communicates with passenger communication terminals 1 carried by passengers of the mobile vehicle and receives information provided by the passenger communication terminals 1 about problems occurring in the passenger compartments of the mobile vehicle, and recording devices (recording devices 5 and 20) that record the information provided from the passenger communication terminals, and the information provision processing device certifies that the information provided from the passenger communication terminals is information about problems occurring in the passenger compartments of the mobile vehicle, provided that the passenger communication terminals receive the device-specific signal from the signal transmitter. This makes it possible to collect highly reliable information about criminal acts and the like occurring in passenger cars.

[0054] Furthermore, the signal transmitter is an access point for wireless communication, and is provided in each of the multiple passenger rooms of the mobile body, and 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 provided in each passenger room, 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 provided by the information providing processing device is a report of the occurrence of the problem and / or a video taken of the problem, so that alerts from victims or witnesses of crimes and the like and video taken by victims or witnesses of crimes and the like can be collected and recorded with high reliability.

[0056] The information providing processing device 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 matches operation information of the mobile body. In this way, by acquiring information about the movement of the mobile body and confirming its consistency, the reliability of the provided information can be more highly evaluated.

[0057] Furthermore, the recording device records the information provided in real time from the passenger communication terminal, which allows the recording device to manage the time information of the provided information, thereby ensuring its reliability.

[0058] The vehicle is further equipped with 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 provision processing device, the signal transmitter is identified from a signal unique to the device used for the authentication, and the image capture of the passenger compartment corresponding to the identified signal transmitter is recorded in the recording device as the image capture result related to the problem. Therefore, by correlating the information provided by the passengers with the image capture results of the on-board camera, it becomes possible to collect a wider variety of information on criminal acts, etc.

[0059] In other words, the disclosed system can prove that the time and location of alerts and captured video from passenger communication devices of traveling passengers match the time and location of the moving vehicle, making them admissible as evidence. As a result, incidents can be identified in real time, and victims can be protected and suspects can be taken into custody at the train's arrival station. Examples of what the disclosed system enables are as follows: (1) A victimized passenger can issue an alert using their smartphone, and the time and location of the alert can be identified and verified as having been sent from the train. A third party other than the victim (e.g., the railway company) can verify that the alert was definitely sent from the train. (2) A passenger who witnesses a criminal act or other crime can use their smartphone to take a video, identify the time and location of the video, and verify that the video was definitely taken on the train. A third party other than the witness (e.g., the railway company) can verify that the video was definitely taken on the train. (3) The passenger's location on the train (e.g., car number) and the shooting angle can be identified, and it can be verified that the video was taken from a specific location on the train. It can be verified that the video was definitely taken from a specific location on the train. (4) When the on-board system detects an alert, it estimates the location of the incident based on the above verification and records high-resolution video using an on-board camera installed near the location. It can verify the identification of the car in which the victim is located. (5) If the suspect is suspected to be moving within the train, it can change the shooting settings of the camera in the destination car in advance (high resolution, high rate) and wait there. It can obtain video with high evidentiary value. (6) It can proactively transmit all or part of the video of the incident to the ground system, the train's next arrival station, and the station attendant's terminal. This contributes to communication with the victim and the cameraman of the incident, protection of the victim, and arrest of the suspect. (7) It can link on-board cameras with station cameras in the ground system. It will also be possible to continue tracking suspects using cameras at stations.
