Description

This disclosure relates to a system and method for preventing rushed boarding.

Rushing to board trains is not only dangerous for the people who rush, but it also causes train delays and is a major problem. However, to date, only limited measures have been taken to prevent people from rushing to board trains, such as announcements and posters in stations and on trains.
Alternatively, in Patent Document 1 and elsewhere, attempts have been made to prevent people from rushing to board trains by installing platform doors, but such a method requires high costs for installing the platform doors.

Japanese Patent No. 3029830

By the way, people who try to run onto trains seem to judge that they can get on the train by taking into account the speed at which the doors open and close, and the speed at which they are running. However, such judgment is often underestimated.
Therefore, an object of the present invention is to provide a system and method for preventing rushed boarding, which prevents rushed boarding by clearly indicating the time when boarding is not permitted.

In order to achieve the above object, a system for preventing rush boarding according to one aspect of the present invention comprises:
A restraint system for restraining rush boarding, the restraint system having an image forming device installed in a boardable moving body or a boarding/disembarking area,
The image forming device includes at least a drawing unit capable of displaying, in the boarding/disembarking area, a boarding signal indicating a boarding state for the moving body and a refusal signal indicating that the boarding state has ended;
A control unit that controls the drawing unit,
The control unit causes the drawing unit to complete changing the display from the boarding signal to the refusal signal before the boarding/alighting door of the moving body is completely closed.

In order to achieve the above object, a method for suppressing last-minute boarding according to one aspect of the present invention includes:
A method for preventing rush boarding using an image forming device, comprising:
The image forming device is capable of displaying at least a boarding signal indicating a boarding state of a boardable moving body and a refusal signal indicating that the boarding state has ended in a boarding/disembarking area,
Before the boarding/alighting door of the vehicle is completely closed, the change of the display by the image forming device from the boarding signal to the refusal signal is completed.

The above-mentioned system and method for preventing rushing to board a plane completes changing the display from the boarding signal to the refusal signal by the drawing unit before the boarding/alighting door of the moving body is completely closed. In other words, the signal is switched to the refusal signal before the boarding/alighting door is completely closed, and the signal is already switched to the refusal signal when the boarding/alighting door closes, so that it is possible to dissuade people who try to rush to board at the dangerous moment just before the boarding/alighting door closes.

The present invention provides a system and method for preventing rushed boarding that clearly indicates the time when boarding is not permitted.

First Embodiment
FIG. 1 is a diagram showing a station in which a rush-boarding prevention system 1 (hereinafter simply referred to as system 1) according to a first embodiment of the present invention is installed. In the example shown in FIG. 1, the system 1 displays a boarding signal B and a refusal signal C on the station platform using an image forming device 10 installed in the station, thereby preventing rush-boarding. In this embodiment, a train is taken as an example of a boardable mobile body. The doors of the train are an example of an entrance/exit for a mobile body. Note that in FIG. 1, for convenience of drawing, only the outline of the feet of a person F waiting for a train on the platform is drawn.

Figure 2 is a block diagram of the system 1 for preventing rushed boarding according to this embodiment. As shown in Figure 2, the system 1 includes an image forming device 10, a door sensor 13, a sound identification unit 14, a broadcast detection unit 15, and a camera 16.

The image forming device 10 is a device capable of drawing any image in the irradiation area A. The irradiation area A is indicated by a dashed line in FIG. 1. The image forming device 10 has a drawing unit 11 and a control unit 12 that controls the drawing unit 11. The image forming device 10 is installed on the ceiling or eaves 20 of the platform, and projects light onto the platform (boarding and disembarking area) to display a boarding signal B and a refusal signal C.

The door sensor 13 is provided on the train and outputs a refusal start signal to the control unit 12 when it receives a closing signal to close the train door D. The door sensor 13 may also be configured to output a boarding start signal to the control unit 12 when it receives an opening start signal to start opening the train door D, or when it receives an opening completion signal indicating that the opening of the train door D has been completed.

The sound identification unit 14 outputs a rejection start signal to the control unit 12 when it identifies a station staff whistle or a departure melody broadcast at the station, which indicates that passengers have boarded the train. The sound identification unit 14 is composed of, for example, a microphone and a microprocessor that analyzes the electrical signal acquired by the microphone. The sound identification unit 14 may be provided on the train or within the station premises.

The broadcast detection unit 15 is installed within the station, and outputs a rejection start signal to the control unit 12 when it receives a signal to broadcast a departure melody. The broadcast detection unit 15 is composed of an electronic circuit that acquires a signal output to a broadcasting device within the station, for example.

The camera 16 is capable of capturing images of the station premises, capturing images of the train and person F on the platform. The camera 16 outputs the captured images to the control unit 12. In this embodiment, the control unit 12 is configured to be able to determine, based on the images captured by the camera 16, whether the train has stopped at a predetermined position within the station premises, and whether person F on the platform has completed boarding. The camera 16 may also be provided on the train or on the platform.

The drawing unit 11 can display at least a boarding signal B (FIG. 4(a)) indicating that it is possible to board the train, and a refusal signal C (FIG. 4(c)) indicating that the boarding status has ended, on the station platform. For example, the drawing unit 11 can be configured to display the boarding signal B and the refusal signal C in the illuminated area A (FIG. 1) on the platform between the door D of the stopped train and the person F in the front row waiting to board. The boarding signal B and the refusal signal C differ in at least one of the drawing area, drawing color, drawing shape, blinking period of the drawing area, and the characters to be drawn. For example, the boarding signal B can be an image as shown in FIG. 4(a), and the refusal signal C can be an image as shown in FIG. 4(c). Note that the boarding signal B and the refusal signal C shown in FIG. 4 are merely examples, and the present invention is not limited thereto.

3 is a time chart showing the changes in events and cues on platforms and trains. The left side of the figure shows events on platforms and trains, and the right side of the figure shows cues that are displayed.
As shown in Fig. 3, when a train enters a platform and stops, the control unit 12 causes the drawing unit 11 to display a boarding signal B. For example, when the control unit 12 determines that a train has entered a platform and stopped based on an image acquired by the camera 16, it causes the drawing unit 11 to display the boarding signal B shown in (a) of Fig. 4.

The timing to start the boarding signal B may be when the train door D is opened or when the opening of the train door D is completed, unlike the timing shown in Fig. 3. For example, the control unit 12 may be configured to cause the drawing unit 11 to display the boarding signal B when a boarding start signal is acquired from the door sensor 13. Alternatively, the control unit 12 may be configured to determine whether the door D has started to open or has been opened, based on an image acquired by the camera 16, and cause the drawing unit 11 to display the boarding signal B based on the results of this determination.
It is preferable that the control unit 12 causes the drawing unit 11 to display the boarding signal B at least when the train door D is fully open.

The control unit 12 completes the change of the display from the boarding signal B shown in FIG. 4(a) to the refusal signal C shown in FIG. 4(c) before the train door D is completely closed.
For example, the control unit 12 may be configured to start displaying the refusal signal C when the closing of the train door D starts. Specifically, when the control unit 12 acquires a refusal start signal from the door sensor 13, the control unit 12 starts changing the display from the boarding signal B to the refusal signal C.
Alternatively, the control unit 12 may be configured to start changing the display from the boarding signal B to the rejection signal C when it obtains a rejection start signal output from the sound recognition unit 14 upon recognizing a station attendant's whistle or a departure melody broadcast at the station, indicating that passengers have boarded.
Furthermore, the control unit 12 may be configured to start changing the display from the boarding signal B to the rejection signal C when it acquires a rejection start signal output from the broadcast detection unit 15 when the departure melody is broadcast.

In this embodiment, the control unit 12 gradually changes the display mode from the boarding signal B to the refusal signal C, as shown in (a) to (c) of Figure 4.
As shown in Fig. 4A, the boarding signal B is a display in which light is projected in two stripes separated by a distance equal to or greater than the width of the fully open door D. For example, the boarding signal B is depicted with a white light.
4C, the refusal signal C is a display in which light is projected in a stripe shape extending around the center of the door D when the door D is completely closed. For example, the refusal signal C is drawn with a red light.

Figure 4(b) shows the intermediate state when the display is changing from boarding signal B to refusal signal C. In this embodiment, the control unit 12 causes the drawing unit 11 to gradually narrow the gap width in boarding signal B to change it to refusal signal C. This intermediate state may be, for example, a gradual change in the color of the light from white to red, or the color may remain white in Figures 4(a) and (b) and change to red when the display in Figure 4(c) is displayed.

Returning to FIG. 3, the rejection signal C is displayed after the rejection start signal is acquired and before the closing of the door D is completed. In this embodiment, when the control unit 12 acquires the rejection start signal output from the door sensor 13 when a closing signal to close the train door D is received, the control unit 12 causes the drawing unit 11 to display the rejection signal C. In this embodiment, the control unit 12 causes the drawing unit 11 to display the rejection signal C immediately after acquiring the rejection start signal.

In this manner, the present system 1 has an image forming device 10 installed in a boardable vehicle or in a boarding/disembarking area, and is intended to prevent rushed boarding.
The image forming device 10 includes at least a drawing unit 11 capable of displaying, in a boarding/disembarking area, a boarding signal indicating that a boarding state of the moving object is available and a refusal signal indicating that the boarding state has ended;
A control unit 12 that controls the drawing unit 11,
The control unit 12 causes the drawing unit 11 to complete changing the display from the boarding signal to the refusal signal before the boarding/alighting gate D of the moving body is completely closed.

In addition, the method for suppressing last-minute boarding according to the present embodiment includes the steps of:
A method for suppressing rush boarding using an image forming device 10, comprising:
The image forming device 10 is capable of displaying at least a boarding signal indicating a boarding state of a boardable moving body and a refusal signal indicating that the boarding state has ended in the boarding/disembarking area,
Before the boarding/alighting door D of the moving body is completely closed, the change of the display by the image forming device 10 from the boarding signal to the refusal signal is completed.

By the way, people who try to run onto a train seem to decide that they can board the train by taking into account the opening and closing speed of door D and the speed at which they run in. However, it is actually required not to board the train when door D starts to close.
The system 1 according to the present embodiment described above causes the drawing unit 11 to complete the change in display from the boarding signal B to the refusal signal C before the train door D is completely closed. In other words, the signal is switched to the refusal signal C before the door D is completely closed, and the signal is already switched to the refusal signal C when the door D is closing, so that a person who tries to rush in at the dangerous timing just before the door D closes can be dissuaded from rushing in to board the train.

In addition, in the conventional method of informing passengers of the timing when they cannot board the train by using a sound such as the voice of a station attendant or a melody, Person F who rushes onto the train may excuse himself by saying that he boarded the train before the sound was made.
According to the present system 1, the timing when boarding is not permitted is displayed not by sound but by visual means. Therefore, for example, by using the records of the camera 16, it is possible to verify whether the boarding signal B or the refusal signal C was displayed when the person F boarded. This makes it difficult for a person who rushes to board to make excuses, and rushing to board can be effectively prevented.

Alternatively, in the conventional method of using a sound to notify the passenger when it is not possible to board the train, there is anticipated a type of person F who, upon hearing a sound while walking down stairs, will accelerate and jump onto the train. In order to deal with this type of person F, attempts have been made to reduce the volume of the sound notifying the passenger when it is not possible to board the train or to eliminate the sound.
According to this system 1, the timing when boarding is not allowed is notified in a visible manner, not by sound, so that person F who is in the middle of going up the stairs is not notified of the timing when boarding is not allowed, and behavior such as accelerating from the middle of the stairs to jump onto the train can be suppressed.

In this embodiment, as shown in FIG. 3, it is preferable that the control unit 12 causes the drawing unit 11 to maintain the display of the refusal signal C at least until the train starts moving.
With this configuration, the refusal signal C is displayed not only at the moment when boarding is no longer possible, but continues to be displayed from the time boarding is no longer possible until the train starts moving. This makes it easy to grasp the timing when not only person F who is trying to rush onto the train, but also people around him/her will be unable to board. It is easy to grasp that there is person F who is trying to board at a time when people around him/her cannot board, which makes it easier to deter people who are trying to rush onto the train.
For example, the control unit 12 can be configured to stop displaying the refusal signal C when it is determined that the train has started moving based on an image captured by the camera 16.

In this embodiment, as shown in Figure 1, the drawing unit 11 is configured to be able to display a boarding signal B and a refusal signal C on the platform between the door D of the stopped train and the front row of passengers waiting to board.
Since the boarding signal B and the refusal signal C are displayed at the feet of passengers in the front row waiting to board and in front of door D through which they are about to board, a person F about to board can easily check the boarding signal B and the refusal signal C. Furthermore, in the case where the image forming device 10 is a device that projects light onto the platform, the light projected onto the platform is unlikely to be blocked by waiting passengers, trains, etc.
Furthermore, the boarding signal will be displayed in the line of sight of people who are using mobile devices such as smartphones while waiting for a train, encouraging people who are engrossed in using their devices to board the train.

In the first embodiment described above, the system 1 is configured to include the door sensor 13, the sound discrimination unit 14, the broadcast detection unit 15, and the camera 16, but the system 1 may be configured to include any one or more of these. Alternatively, the system 1 may be configured to include any one or more of the door sensor 13, the sound discrimination unit 14, and the broadcast detection unit 15, and the camera 16.

Second Embodiment
5 is a diagram showing a station in which the rush-boarding prevention system 101 according to the second embodiment of the present invention is installed. In the above-described first embodiment, an example in which the image forming device 10 is installed under the eaves 20 of the platform has been described, but the present invention is not limited to this example.

As shown in FIG. 5, the image forming device 110 may be provided on the side of the train and configured to project light onto the platform to display the boarding signal B and the refusal signal C. In this case, the image forming device 110 may be provided, for example, on the side of the train, near door D. The position of door D may differ when a different train formation stops, and if the image forming device 110 is provided on the platform, it will be necessary to change the drawing area each time, but if the image forming device 110 is provided on the train, it can always be drawn near door D.

When installing the image forming device 110 on the side of a train, it is preferable to install it as low as possible. For example, it is preferable to install the image forming device 110 at a height of 1 meter from the road surface, and more preferably within 50 centimeters. The closer the distance between the road surface and the image forming device 110, the more clearly the boarding signal B and the refusal signal C can be depicted, since the light projected by the image forming device 110 reaches the road surface before it is significantly attenuated. In addition, the light projected by the image forming device 110 is more likely to reach the road surface without being obstructed by a person F, etc.

Third Embodiment
6 as a system for preventing rushed boarding according to a third embodiment, the image forming device 210 may be a display embedded in the platform, which has a screen flush with the platform and displays the boarding signal B and the refusal signal C on the screen. With such a configuration, inconveniences such as light being blocked by a person F or an insufficient amount of light causing an unclear image do not occur.

<Fourth embodiment>
7 is a time chart showing events and changes in signals on platforms and trains in the fourth embodiment of the present invention. In the first embodiment described above, the control unit 12 is configured to cause the drawing unit 11 to display the refusal signal C when it receives a refusal start signal from the door sensor 13. However, the configuration shown in FIG. 7 may also be used.

In FIG. 7, the refusal start signal is configured to be acquired from the sound identification unit 14 or the broadcast detection unit 15. In this case, the closing of the door D starts one beat after the signal from the station staff or the station announcement, so it may take some time from the acquisition of the refusal start signal to the actual start of closing of the door D. Therefore, in this embodiment, when the refusal start signal is acquired, the control unit 12 causes the drawing unit 11 to cancel the boarding signal B and display a warning signal. Furthermore, when it is determined that the closing of the door D has started based on the image from the camera 16, the display of the refusal signal C is started. By configuring in this way, the actual movement of the door D and the start of the refusal signal C can be linked. For example, if the boarding signal is a blue triangle with one vertex facing the train and the refusal signal is a red x, the warning signal can be displayed as a yellow rectangle.

In the above description, the present invention is applied to a train as a boardable mobile body, but the present invention is not limited to this. For example, the present invention can be applied to a bus, airplane, ship, underwater vehicle, flyable vehicle, or other mobile body that has a set boarding time. The present invention is also suitable for application to public transportation mobile bodies that are required to operate according to a schedule.
For example, when boarding an airplane or ship, one end of a passageway such as a ramp is connected to the aircraft's boarding gate, and the other end of the passageway is connected to a waiting room. People who wish to board the airplane or ship wait in front of a gate that separates the waiting room from the passageway. In the present invention, as in the above-mentioned embodiment, a boarding signal and a refusal signal are displayed on the ground near the gate, thereby preventing people from rushing to board. That is, the boarding and disembarking area in the present invention where the boarding signal and the refusal signal are displayed is the ground where passengers who wish to board a moving object are waiting. The boarding and disembarking area means the ground near the location where the door of a stopped aircraft is located, or the ground near the gate that separates the passageway extending from the aircraft's boarding gate from the waiting room.

Although an embodiment of the present invention has been described above, it goes without saying that the technical scope of the present invention should not be interpreted as being limited by the description of this embodiment. This embodiment is merely an example, and it will be understood by those skilled in the art that various modifications of the embodiment are possible within the scope of the invention described in the claims. The technical scope of the present invention should be determined based on the scope of the invention described in the claims and its equivalents.
