  The control unit of each display device acquires information in SA1 of FIG. Specifically, although it is arbitrary, for example, the control unit 15 of the vehicle-side display device 1 acquires the display device ID from the recording unit 14 and captures an image of the inside of a train with the imaging unit 12 and the imaging unit 12 The captured image is acquired from the above, and the date and time when the image was captured is acquired from a clock means (for example, a clock circuit etc.) not shown, and the present position detection (not shown) of the train provided with itself. Means (for example, GPS, a gyro sensor, distance sensor (all not shown), means for detecting the current position (coordinates) and direction etc. of the train by a known method, etc.) Get latitude coordinates. Here, for example, the control unit 15 of the vehicle-side display device 111 acquires “ID 111” as the display device ID, and acquires an image in the train, and “August 30, 18:00 as the date and time. "45 seconds" is acquired, and "(x11, y11)" is acquired as coordinates of a train.

  In SA1, for example, the control unit 25 of the home-side display device 2 acquires the display device ID from the recording unit 24, and the imaging unit 22 captures an image of the home, and the captured image from the imaging unit 22 And the date and time at which the image was captured from a clock means (for example, a clock circuit etc.) (not shown). Here, for example, the control unit 25 of the home-side display device 211 acquires “ID 211” as the display device ID, and acquires an image of the home, and “August 30, 18: 00 45 as the date and time. Get Seconds.

  At SA2 in FIG. 6, the control unit of each display device transmits information. Specifically, although optional, for example, the control unit of each display device transmits the information acquired in SA1 to the center device 3 via the communication unit of each display device. Here, for example, the control unit 15 of the vehicle-side display device 111 includes “ID 111”, an image in a train, “August 30, 18:00:45”, and “(x11, y11)” (hereinafter, these Information is referred to as “transmission information of the vehicle-side display device 111”. Also, here, for example, the control unit 25 of the home-side display device 211 has “ID 211”, an image of the home, and “August 30, 18: 00: 45” (hereinafter, these information are “home-side display Transmission information of the apparatus 211).

  On the other hand, at SB1 in FIG. 6, the control unit 33 of the center apparatus 3 receives the information. Specifically, although it is arbitrary, the information transmitted from each display device at SA2 is received via the communication unit 31. Here, for example, “transmission information of the vehicle-side display device 111” and “transmission information of the home-side display device 211” are received.

  The control unit 33 of the center apparatus 3 stores information at SB2 in FIG. Specifically, although it is arbitrary, for example, the monitoring information of the monitoring information DB 322 of FIG. 2 and the image information of the image information DB 323 are stored based on the information received at SB1. In detail, for example, when the information from the vehicle-side display device 1 is received at SB1, the display device ID, the image captured by the imaging unit 12, the date and time when the image was captured, and the coordinates of the train are acquired from the received information. Then, the information corresponding to the acquired display device ID is stored in the display device ID in FIG. 5, and the information corresponding to the acquired date and time is stored in the imaging time information in FIG. The coordinates are stored in the imaging position information, and the image captured by the acquired imaging unit 12 is stored in a file format with a file name uniquely identifiable as image information in the image information DB 323 of FIG. The stored file name is stored in the captured image information of FIG. Here, for example, when “transmission information of the vehicle-side display device 111” is received at SB1, the image in the train is stored in the image information DB 323 of FIG. 2 and the top information about the ID 111 of FIG. Store

  For example, when the information from the home-side display device 2 is received at SB1, the display device ID, the image captured by the imaging unit 22, and the date and time of capturing the image are acquired from the received information. Similarly to the case where the information from the vehicle-side display device 1 is received, the display phase ID of FIG. 5, imaging time information, captured image information, and image information of the image information DB 323 of FIG. 2 are stored. Although the imaging position information in FIG. 5 can be stored by any method, for example, the home-side display device 2 is installed focusing on the fact that the home-side display device 2 is fixed to the station's home and does not move. Information that stores the coordinates of the station's home and the display device ID of the home-side display device 2 in association with each other is recorded in the recording unit 32, and the information described above is referred to. The coordinates corresponding to the acquired display device ID are specified, and the information corresponding to the specified coordinates is stored as the imaging position information of FIG. Here, for example, when “transmission information of the home-side display device 211” is received at SB1, the image of the home is stored in the image information DB 323 of FIG. 2, and the top information about the ID 211 of FIG. Store. This completes the information storage process.

(Process-display control process)
Next, display control processing will be described. FIG. 7 is a flowchart of the display control process. The display control process is a process that is roughly executed by the center device 3, and more specifically, is a process of switching the image displayed on each display device. Although the timing to execute this display control process is arbitrary, for example, after turning on the power of each device of the railway information display system 100, the execution is started and it is assumed to be repeatedly executed, and the explanation is started from the start Do. FIG. 8 is a diagram illustrating a promotional image, and FIG. 9 is a diagram illustrating a warning passenger image.

  In SC1 of FIG. 7, the display control unit 333 displays an advertisement image. Specifically, although it is arbitrary, for example, it is assumed that a plurality of advertisement images including the advertisement image of FIG. 8 are stored in the recording unit 32, and the plurality of advertisement images stored in the communication unit By transmitting to each display device via 31, the display unit of each display device is displayed. In this case, each display device receives the above-mentioned plurality of advertisement images and stores them in its own recording unit, switches the plurality of stored advertisement images at predetermined time intervals, one by one. It will be displayed on the display unit. Here, for example, the advertisement image or the like of FIG. 8 is sequentially displayed on the display unit of each display device.

  The acquisition unit 331 acquires information in SC2 of FIG. Specifically, although it is arbitrary, for example, the information stored in the equipment information DB 321, the monitoring information DB 322, and the image information DB 323 is acquired. Here, for example, the equipment information in FIG. 4, the monitoring information in FIG. 5, and the image stored in the image information DB 323 are acquired.

  In SC3 of FIG. 7, the detection unit 332 determines whether or not there is a passenger fraud based on at least a part of the information acquired in SC2. Specifically, although it is arbitrary, for example, the type of fraudulentness of the passenger to be determined, the general behavior of the passenger in the case of fraudulent behavior, or the environment to determine the fraud (for example, the structure of a station, train The predetermined criteria are generated in consideration of arbitrary events such as the manner of driving in, and determination is made based on the generated criteria. Here, for example, as described above, the passenger's fraud is "corruption return", and after the train 91 of FIG. 1 arrives at the second terminal station, the second train 92 departs from the second terminal station. In the manner of getting in the train, it is generally considered that the passenger who does an illegal return ride has made a transfer, noting that the transfer from the train 91 to the train 92 is performed at this terminal 2 station. Determine based on.

  Although the method of determining whether or not this transfer has been made is arbitrary, for example, first, the imaging position of the image is specified from the imaging position information and the imaging image information of FIG. 5, and the imaging time information of FIG. And the imaging time of an image is specified from imaging image information. Next, based on the specified image pickup position, the image picked up at Terminal 2 station is specified, image recognition is carried out for the specified image by any method, and an image showing the same person is specified, as shown in FIG. With reference to the display device ID, the captured image information, and the facility information of FIG. 4, it is determined whether or not the image in the train 91 and the image in the train 92 exist in the image in which the above identified same person is shown If it is determined that there is no passenger, it is determined that the passenger has not changed trains, and if it is determined that there is one, the imaging time of the image in the train 91 is determined based on the imaging time specified above. And when it is judged whether the time difference of the imaging time of the image in the train 92 is within a predetermined time (for example, 5 minutes to 10 minutes) and it is judged that it is not within the predetermined time, the passenger does not change trains Judge as a thing, meanwhile If it is determined that it is within the time, the passenger decides to have conducted the transfer. Then, if it is determined in the determination of SC3 that there is no transfer, it is determined that there is no injustice of the passenger without detecting the injustice of the passenger (NO in SC3), and the process is ended. If it is determined that the transfer has been performed, the passenger's fraud is detected, and it is determined that the passenger is fraudulent (YES in SC3), and the process proceeds to SC4.

  Here, for example, the passenger P1 in FIG. 1 is shown in each image specified by “captured image information” = “File111_1”, “File113_5”, “File211_2”, “File211_3”, and “File211_4” in FIG. In addition, the position of the train 91 at which the imaging position information “(x11, y11)”, “(x33, y33)”, and “(x22, y22)” in FIG. It will be described below as corresponding to the position of the train 92 and the position of the line 1 home east side. First, the image pickup position of the image specified by "File111_1" is stopped at "Terminal 2 station" from "image pickup position information =" (x11, y11) "and" imaged image information "=" File 111_1 "in FIG. It specifies that "the position of the train 91" and the like. Next, from "imaging time information" = "0830180045" and "captured image information" = "File 111_1", the imaging date and time of the image specified by "File 111_1" is "August 30, 18: 00:45" Identify etc. Next, based on the specified image pickup position, the image picked up at the second terminal station is specified, image recognition is performed on the specified image by an arbitrary method, and the image showing the passenger P1 who is the same person is shown in FIG. "Imaged image information" = "File111_1", "File113_5", "File211_2", "File211_3", and "File211_4" specify each image specified, the display device ID of FIG. 5, the captured image information, and FIG. With reference to the equipment information of the image, there is an image in the train 91 (image of "File 111_1") and an image in the train 92 (image of "File 113_5") in the image showing the identified passenger P1 described above Because the shooting date and time of these images are “August 30, 18: 00: 45” and “August 30, 18: 03: 46”. These time differences are within a predetermined time, judges determines that performing the transfer, to detect illegal passengers, that there is illegal passengers.

  The detection unit 332 at SC4 in FIG. 7 identifies the passenger. Specifically, although it is arbitrary, for example, the passenger who is determined to have the passenger fraud in SC3 is identified. Here, for example, the passenger P1 of FIG. 1 is specified.

  In SC5 of FIG. 7, the display control unit 333 displays a warning passenger image. Specifically, for example, the warning passenger image may be displayed on the display units of all the display devices, or the warning image may be displayed on the display unit of each display device around the passenger specified in SC4. Although a passenger image may be displayed, here, for example, a case where it is displayed on the display unit of each display device around the passenger will be described. In this case, after identifying the current position of the passenger identified in SC4, and identifying each display device around the identified current position, a warning passenger image is generated, and the generated warning passenger image is specified. It is displayed on the display unit of each display device. Specifically, first, the latest image captured by each display device is specified from the imaging time information and the captured image information in FIG. 5 among the information acquired in SC2, and the identified latest image in the image information DB 323 With reference to FIG. 5, the image in which the passenger specified in SC4 is shown is specified, and the display device ID corresponding to the specified image is acquired with reference to the display device ID and the captured image information of FIG. Next, referring to FIG. 4, the position corresponding to the installation location information corresponding to the acquired display device ID is identified as the current position of the passenger specified in SC4, and each of the acquired display device IDs Identify each display device around the current position where the display device was identified. Next, after performing appropriate communication with each display device, the imaging unit of each identified display device captures an image of the passenger identified in SC4, and performs mosaic processing of the face in the image of the imaged passenger To generate a warning passenger image. After that, the generated warning passenger image is displayed and warned in place of the advertisement image displayed in SC1 on the display unit of each of the above identified display devices.

  Here, for example, based on the imaging time information and captured image information in FIG. 5 among the information acquired in SC2, for example, the image of “File111_5” in FIG. 5 as the latest image captured by each display device, “File 113_5” The image, the image of "File 211_5", etc. are specified, and the specified image is referred to, the image of "File 113_5" is specified as the image including the passenger P1 specified at SC4, and the "display device ID" in FIG. “ID 113” is acquired as a display device ID corresponding to the identified image of “File 113 — 5” with reference to “ID 113” and “captured image information” = “File 113 — 5”. Next, referring to FIG. 4, the position corresponding to the “TrB1 rear left door” corresponding to the acquired “ID 113” is identified as the current position of the passenger P 1, and the vehicle of the acquired “ID 113” The side display device 113 is specified as one around the current position of the passenger P1. Next, appropriate communication is performed with the vehicle-side display device 113, and the passenger P1 is imaged by the imaging unit 12 of the identified vehicle-side display device 113, and the face is mosaiced in the imaged passenger P1 image. By processing, the warning passenger image of FIG. 9 is generated. After that, the warning passenger image of FIG. 9 is displayed for a predetermined time instead of the advertisement image of FIG. In this case, for example, the passenger P1 visually recognizes the warning passenger image shown in FIG. 9, recognizes that he / she is being monitored, and is aware again that he / she is in the wrong state to increase guilt. It will be self-indulgent to take a wrong turn back.

  In SC6 of FIG. 7, the display control unit 333 determines whether or not the warning passenger image displayed in SC5 is to be returned to the advertisement image. Specifically, although it is optional, whether or not a predetermined time (for example, 20 seconds to 30 seconds, etc.) has elapsed since the warning passenger image is displayed at SC5 with reference to a timing unit (not shown), for example Based on Then, if the predetermined time has not passed, the SC6 is repeated until it is determined that the warning passenger image is to be returned to the advertisement image without determining that the warning passenger image is to be returned to the advertisement image (NO in SC6). Run. When a predetermined time has elapsed, it is determined that the warning passenger image is returned to the advertisement image (YES in SC6), and the process proceeds to SC7.

  In SC7 of FIG. 7, the display control unit 333 causes the advertisement image to be displayed. Specifically, for example, each display device displaying the passenger image for warning is specified in SC5, and in each specified display device, the same processing as SC1 is performed to display the advertisement image Let This completes the display control process. Note that, as described above, this display control process is repeatedly executed. However, when the advertisement image is already displayed on the display unit of each display device in SC1 at the time of repetitive execution, the display control process is performed. The execution of SC1 may be omitted.

(Effect of the embodiment)
As described above, according to the present embodiment, by detecting the injustice of the passenger on the train based on the acquired internal image, for example, the injustice of the passenger is detected regardless of the radio wave condition in the train. As such, it is possible to reliably warn of the passenger's fraud. Furthermore, until the passenger's fraud is detected, the first image is displayed on the display unit 13 of the vehicle display 1, and when the passenger's fraud is detected, the second image warning of fraud is displayed on the vehicle display By displaying the first image instead of the first image in at least a part of the display unit 13, for example, the vehicle-side display device 1 can be effectively used even before detecting a passenger's fraud. Also, for example, since the first image is displayed before detecting the passenger's fraud, the passenger's attention can be drawn to the vehicle-side display device 1, so the first image was switched to the second image. In this case, the second image can be reliably viewed by the passenger who detected the fraud, and the effect of the warning can be improved.

  Further, by displaying the image corresponding to the image of the passenger of the train as the second image, for example, the image that the passenger is being monitored can be given, so that the effect of the warning can be further improved. It becomes.

  In addition, since the imaging unit 12 is configured integrally with the vehicle display device 1, for example, the face of the passenger can be captured in the front direction of the imaging unit 12 by guiding the line of sight of the passenger to the vehicle display device 1 It becomes possible to make it easy to identify a person.

  In addition, when the detection unit 332 detects an unauthorized return, it is possible to warn, for example, an unauthorized return of a passenger.

  In addition, for example, it is possible to detect a matched passenger in the internal image of the transfer source vehicle and the transfer destination vehicle, so that it is possible to surely warn of the passenger's unauthorized return.

[Modification to the embodiment]
Although the embodiments according to the present invention have been described above, the specific configuration and means of the present invention can be arbitrarily modified and improved within the scope of the technical idea of each invention described in the claims. Can. Hereinafter, such a modified example will be described.

That is, the specific form of the distribution and integration of each part is not limited to the illustrated one, and all or a part thereof can be configured to be functionally or physically dispersed or integrated in any unit. In addition, the “device” in the present application is not limited to one configured by a single device, but includes one configured by a plurality of devices. For example, the center device 3 is configured to be distributed to a plurality of devices configured to be mutually communicable, and a part of each part of the control unit 33 is provided in a part of the plurality of devices. Another part of each part of the control unit 33 may be provided in another part. Further, at least a part of the information recorded in the center device 3 or at least a part of each part of the control unit 33 may be provided in each display device of the railway information display system 100. Further, the imaging unit of each display device may be provided as a separate device separated from each display device.

(On fraud detection (1))
Further, in the above-described embodiment, in the case where fraud is detected based on the image in the train 91 and the image in the train 92 (that is, the image captured by the vehicle display 1) in SC3 of FIG. Although it demonstrated, not only this but in order to detect a fraudulent return boarding, for example, the picture picturized with home side display 2 may also be used. Specifically, the image on the home-side display device 2 may be used to detect an unauthorized turn on the vehicle after grasping how a passenger changes from the train 91 to the train 92. Here, for example, as described above, the image of “captured image information” = “File211_2”, “File211_3”, and “File211_4” in FIG. To detect fraud. When configured in this manner, the accuracy of fraud detection can be improved.

(On fraud detection (2))
Further, in the above embodiment, based on the fact that transfer was performed within a predetermined time by train 92 from train 91 at terminal 2 station, which is a station outside the boarding right holding section, at SC3 in FIG. 7. Although the case of detecting fraud has been described, it is not limited thereto. For example, when the train 91 is operating between the first and second terminal stations in a reciprocating manner, when unauthorized return information is detected at the second terminal station, a passenger gets on the train 91 heading to the second terminal station. If the passenger is on the train 91 traveling from the second terminal station, fraud may be detected.

(About fraud detection (3))
Further, the method of detecting the fraud in SC3 of FIG. 7 of the above embodiment can be applied to a station other than the terminal station (for example, a station next to the first terminal station in FIG. 3, etc.).

(About passenger image for warning (1))
Further, the display mode of the passenger image for warning at SC5 in FIG. 7 of the above embodiment may be arbitrarily changed. For example, as described in the embodiment, the passenger image for warning may be displayed instead of the entire advertisement image (that is, the passenger image for warning may be displayed by deleting the advertisement image). The warning passenger image may be displayed instead of a part of the advertisement image (that is, a part of the advertisement image (for example, a part of the lower right, etc.) is erased to warn the erased part) Passenger images may be displayed). In addition, for example, a warning message such as “A person who has made an unauthorized return will pay a premium fee” may be included in the warning passenger image. Also, for example, a fixed image (for example, an image of a passenger on a train) prepared in advance may be displayed for the warning passenger image.

(About passenger image for warning (2))
In addition, regarding SC5 to SC7 in FIG. 7 of the above-described embodiment, face recognition of the passenger P1 is performed by the imaging unit 12 of the vehicle-side display device 1 and whether or not the passenger P1 faces the warning passenger image The warning passenger image may continue to be displayed until the passenger P1 turns to the direction of the warning passenger image. In addition, for example, when the passenger image for warning is displayed, the advertisement image can not be viewed (or when the technology of "(about the passenger image for warning (1)) is applied, it becomes difficult to see) The warning passenger image may be intermittently displayed by alternately displaying the warning passenger image and the advertisement image in consideration of the above.

(About omission of configuration)
Further, in the above-described embodiment, the home-side display device 2 may be omitted in any case such as when the vehicle-side display device 1 alone can reliably warn of fraud.

(About warning)
Further, in the above-described embodiment, the number of times that it is determined that there is an injustice is counted for the passenger (hereinafter referred to as the injustice determination passenger) that is the basis for determining that there is an injustice in the passenger in SC3 of FIG. After being configured, when the counted number of times exceeds the first predetermined number of times (for example, 4 times to 5 times, etc.), a speaker (not shown) of the vehicle-side display device 1 or the display unit 13 An alarm sound or an alarm message may be output, and when the counted number of times exceeds a second predetermined number of times (for example, a number of times greater than the first predetermined number of times, such as 9 times to 10 times) The warning broadcast may be output via an emergency broadcast system of a train on which the passenger is on board (for example, a system for broadcasting on a train basis or a vehicle basis).

(About analysis of behavior pattern)
In the above embodiment, although one vehicle is specifically illustrated and described in FIG. 1, it is conceivable that a passenger who takes an unauthorized return ride changes the riding vehicle according to the day, etc. The weekly or monthly behavior pattern may be analyzed, and then a vehicle on board may be inferred to detect fraud. When configured in this way, it is possible to detect fraud efficiently.

(About the fraudulent information writing part and the prohibition part)
Further, in the above embodiment, the passenger can use the terminal device carried by himself (for example, a smart phone in which regular commuting information is stored, or a known terminal such as a non-contact type IC card terminal) of the station. An unauthorized information writing unit and a prohibition unit may be provided to the control unit 33 of the center device 3 on the premise that the automatic ticket gate passes. The "corruption information writing unit" is fraudulent information to which fraudulent identification information for identifying that fraud has been made to a terminal device carried by a passenger of a transport vehicle whose fraudulent return has been detected by the detection means. It is a writing means. Further, the "prohibited unit" is a prohibiting means for prohibiting the passage of the passenger of the transport vehicle in the automatic ticket gate based on the fraud identification information of the terminal device written by the fraud information writing means. Although the configuration or processing of the fraudulent information writing unit and the prohibition unit is optional, for example, a surveillance camera may be installed on the station automatic ticket gate to pick up train passengers who enter and exit the automatic ticket gate with this surveillance camera. In addition, with the automatic ticket gate installed at the automatic ticket gate of the station, the fact that the unauthorized return has been detected as the fraudulent identification information and the number of times of detection are made noncontact with the terminal device of the passenger. It may be configured as follows after being configured to be readable and writable.

  For example, the fraud information writing unit acquires the image of the “cheating passenger” from the image information DB 323, and uses the obtained image and the image of the monitoring camera, the “cheating passenger” at the automatic ticket gate of the station. It may be configured to write and store the fraud identification information through the automatic ticket gate apparatus in the identified and identified terminal device of the "incorrect passenger". In this case, for example, the prohibition unit determines whether or not the fraud identification information is stored in the terminal device of the passenger who is going to pass the automatic ticket gate by reading the information of the terminal device via the automatic ticket gate device. If it is determined that the fraud identification information is stored, the gate is opened to permit passage, while if it is determined that the fraud identification information is stored, the gate is closed to inhibit passage. It may be configured to When configured in this way, for example, by prohibiting the passage of the passenger of the train at the ticket gate based on the fraud identification information of the terminal device, for example, at least a passenger who actually performed an incorrect action Because it is possible to guide the passenger who actually did the above to the station staff, it is possible to prevent the recurrence of the fraud, or to pay the compensation for the fraud (for example, the extra charge for the illegal return trip etc.) Is possible.

(About the feature)
In addition, the features of the above-described embodiment and the features of the modification may be combined arbitrarily.
