FIG. 1 shows a schematic configuration of a monitoring system 1 according to the present embodiment. The monitoring system 1 includes a premises device 2 arranged at each of a plurality of stations, and an in-vehicle device 70 of a train 7 that can communicate with the premises devices. The monitoring system 1 captures an image of a station platform with the monitoring camera 10 and transmits the image to the train 7 (on-vehicle device 70) by communication using radio waves in the millimeter wave band (30 GHz to 300 GHz) (hereinafter, referred to as “millimeter wave communication”). In addition, the monitoring system 1 uses the image recognition processing to determine the presence or absence of a person requiring assistance on the platform of the own station or the next station, and transmits an image including the person requiring assistance to the train 7 if it exists. As a result, the operation manager (conductor or driver) of the train 7 assists a person in need of assistance in getting on and off quickly.

  Here, as the premises equipment 2, the premises equipment (A) 2a at Station A and the premises equipment (B) 2b at Station B will be described. The train 7 runs from the A station to the B station, and the A station is the own station and the B station is the next station for convenience.

  The premises device (A) 2a at the station A is a device that monitors the platform (A) 9a of the station A, and includes a station premises server (A) 20a, a home monitoring camera (A) 10a, and a premises inside millimeter wave radio. (A) 30a.

  A plurality of home surveillance cameras (A) 10a, in this case, a first camera (A) 11a, a second camera (A) 12a, and a third camera (A) 13a are installed. Each of the first camera (A) 11a, the second camera (A) 12a, and the third camera (A) 13a has a monitoring area (that is, an angle of view) set, and three monitors the entire home (A) 9a. I do. It should be noted that a specific camera dedicated to detecting the person requiring assistance at the home (A) 9a may be provided.

  The home (A) 9a is provided with an in-premises millimeter-wave radio (A) 30a that performs millimeter-wave communication with the train-side millimeter-wave radio 72 mounted on the train 7. In the millimeter wave communication, two functions of a surveillance video transmission function and a radar function for detecting an incoming train are used. Specifically, when the train 7 enters and enters a communicable area between the train-side millimeter-wave radio device 72 and the premises-side millimeter-wave radio device (A) 30a, the monitoring video is transmitted to the station by millimeter-wave communication using them. It is transmitted from the premises server (A) 20a to the train 7.

  The station premises server (A) 20a controls each device of the premises device (A) 2a, acquires a monitoring video from the home surveillance camera (A) 10a, and controls the premises via the inter-station network 8. From the device (B) 2b, an image of a person requiring support at the next station (that is, station B) is acquired, and a monitor image or a processed image combining the monitor image and the image of a person requiring support is displayed (video for display). The signal is transmitted to the train 7 during or after the incoming line by the above-described millimeter wave communication.

  Also, when it can be recognized from the monitoring video that there is a person requiring assistance at the platform (A) 9a of the station A, the image is transmitted to the in-house device 2 of the preceding station (not shown) as the image of the person requiring assistance at the station A. . The specific configuration of the station premises server (A) 20a will be described later.

  The premises device (B) 2b at the station B has the same configuration as the above-described premises device (A) 2a, and is a device that monitors the home (B) 9b of the B station, and includes a station premises server (B) 20b. , A home surveillance camera (B) 10b, and a premise millimeter-wave radio (B) 30b.

In addition, the video acquisition unit 22 acquires a support-required video from a station ahead of the own station (here, the next station B) via the inter-station network 8.

  The indoor display monitor 23 displays the monitoring images of the home monitoring camera (A) 10a side by side. The in-premises millimeter-wave communication control unit 24 controls the in-premises millimeter-wave wireless device (A) 30 a and performs millimeter-wave communication with the train-side millimeter-wave wireless device 72 of the on-board device 70. The station-to-station communication control unit 25 communicates with the premises device 2 (station premises server 20) of another station connected via the inter-station network 8.

  The video analysis unit 26 analyzes the image of the monitoring video captured by the home monitoring camera (A) 10a and determines whether or not a person requiring support exists in the home (A) 9a. As the determination method itself, a known technique, for example, an image recognition technique using machine learning or AI can be used, and a wheelchair user or a cane user is specified using a reference image or the like.

  The transmission destination determination unit 27 determines the transmission destination of the supporter required video based on the operation status. For example, when all the operating trains stop at all stations, no special judgment is required, and the supporter required image is transmitted to the preceding station. If there is a train that passes through some stations, such as an express train, the next train that is scheduled to enter and stop is any of the stations in front of the own station (here, A station). It is determined whether or not to stop, and it is determined to transmit the supporter required image to the station.

  The display image transmitting unit 28 transmits the support required image to the preceding station and generates a monitoring video to be transmitted to the train 7 entering the own station (station A). The frame containing the person requiring support may be left as it is, or may be a video obtained by trimming a certain area so as to include the person requiring support. At this time, processing is performed so that the position information is included so that the position of the person requiring support can be known. The position information includes a planned train number, a camera number (the number of the whole number), the “head”, “middle”, and “tail” of the home (A) 9a.

  When generating a monitoring image (display image) to be transmitted to the train 7 entering the own station (station A), the display image transmitting unit 28 transmits the image of the home surveillance camera (A) 10a and the image from the next station. An image in which the supporter images are arranged is generated as a display image, and the indoor millimeter-wave communication control unit 24 transmits the image to the train 7 by millimeter-wave communication via the indoor millimeter-wave radio (A) 30a.

  FIG. 3 is a block diagram illustrating a schematic configuration of the vehicle-mounted device 70. The in-vehicle device 70 includes a main control unit 71, a display control unit 73, a train-side millimeter-wave radio device 72, and a train-side display monitor 80.

For example, it is also possible to perform processing such as displaying as shown in FIG. 4D during an incoming line, displaying as shown in FIG. 4E when stopping, and displaying as shown in FIG. 4C after departure. In addition, until the mutual communication is possible at the next station after being out of the mutual communication range, the display of the supporter required video area 84 is continuously displayed immediately before the video is cut off, and the first to third camera video areas are displayed. For 81 to 83, display control for black display may be performed.

  The operation of the monitoring system 1 having the above configuration will be described with reference to the flowchart of FIG. Here, a description will be given of a process of identifying a person requiring support at B station and notifying the train 7 entering the A station. In the premises apparatus (B) 2b at the station B, the video obtained by the home surveillance camera (B) 10b by the home (B) 9b is obtained by the video acquisition unit 22 of the station premises server (B) 20b, and the video analysis unit 26 The presence or absence of a person requiring support in the video is specified (S10).

  The video analysis unit 26 transmits the supporter required image including the specified supporter required to the station premises server (A) 20a of the premises device (A) 2a of the previous station (station A) via the inter-station network 8. It transmits (S11). The supporter required image includes the position information of the supporter required as described above.

  In the premises device (A) 2a of the station A, which is the station in front of the station B, the image acquisition unit 22 of the station premises server (A) 20a transmits the supporter required image transmitted from the station premises server (B) 20b of the station B. Is acquired (S12). Further, the video obtaining unit 22 obtains a monitoring video of the home (A) 9a captured by the home monitoring camera (A) 10a (S13).

  The display image transmission unit 28 generates a display image to be transmitted according to the incoming state of the train 7 (S14). That is, if the train 7 is in the middle of entering the station A and before stopping, the display image is generated only with the camera image of the station A as shown in FIG. When the train 7 enters the station A and stops, for example, as shown in FIG. 4C, a display image is generated by combining an image including a person who needs assistance at the station B and a monitoring image of the station A. If the person requiring support cannot be confirmed, a display (black display or the like) where nothing is shown in the person requiring support image area 84 as shown in FIG. After generating the display image, the display image transmission unit 28 transmits the image to the train 7 by the millimeter wave communication (that is, the in-premises millimeter-wave radio (A) 30a) (S15).

  In the train 7, when the display video is acquired from the station premises server 20 of the premises device (A) 2a by the millimeter wave communication (that is, the train side millimeter wave radio 72) (S16), the display video acquired by the display control unit 73 is obtained. Is displayed on the train-side display monitor 80 (S17).

  As described above, in the train 7, the supporter required image of the next stop station is acquired in advance, and the supporter required and its position information (station name and platform) are displayed in a display area (supporter required image area 84) which is not normally displayed. Location, camera position, etc.) can be displayed. That is, the information of the person who needs assistance (presence or absence and position information) can be notified to the driver or the like in advance. Therefore, after arriving at the train, the driver can watch over the ride of the person who needs assistance at a predetermined place and can quickly assist the ride. In addition, since the presence of a person requiring assistance can be checked at the front station, even if the person requiring assistance falls off the platform, it is possible to be careful in advance and prepare for emergency response (stop operation etc.) Can be. In particular, when the train 7 is a one-man operation with only a driver, prompt support is possible while securing regular operation by grasping in advance the presence or absence of a person requiring assistance and its position.

  Further, when there is a person requiring assistance again at the next station, a process of giving a flag for preferentially displaying the image of the person requiring assistance at the arrival station may be performed until the person requiring assistance is boarded at the arrival station. . For example, data in the station premises server 20 installed at the station is assigned a younger number in the order of each station, and the youngest number is transmitted to the stopped train 7 via millimeter-wave communication via the millimeter wave communication. By displaying the image on the display monitor 80, the image display of the next station can be prevented. After boarding, by recognizing the next station number, it is possible to switch the next station name transmitted to the train side display monitor 80 by the inter-station network 8 and the person requiring assistance at the next station.

  The present invention has been described based on the embodiments. This embodiment is an exemplification, and it will be understood by those skilled in the art that various modifications can be made to the combination of the components, and that such modifications are also within the scope of the present invention.
