Description

  The present invention relates to an information providing system in an escalator.

  In order to improve safety in the use of escalators such as in station premises, it is desirable to provide users with information that alerts them when getting on and off and encourages them to carry handrails that move in synchronization with escalator steps.

  For this reason, conventionally, a part of the floor of the entrance / exit of the escalator is provided with a display unit that is inclined upward with respect to the building floor, and the display unit displays information related to the operation of the passenger conveyor, thereby allowing the user to However, the driving | operation display apparatus which can visually recognize the information regarding the driving | running | working of a passenger conveyor is disclosed from the place comparatively distant from the entrance / exit (refer patent document 1).

  However, the operation display device in Patent Document 1 requires remodeling work on the escalator body and its surroundings. For example, it is difficult to perform remodeling work on an escalator that is already in operation in a station. It was.

  On the other hand, an escalator capable of displaying / moving and displaying an arbitrary image by projecting and displaying an image by a projection device such as a projector on a handrail of an escalator or a wall surface, and an advertisement display device regarding a moving walkway are disclosed. (See Patent Document 2). According to the present invention, an arbitrary image can be displayed / moved and displayed on the handrail and the wall surface of the escalator without modifying the escalator main body and its surroundings.

However, in the display device disclosed in Patent Document 2, an image is projected onto a handrail from a projection device installed above an escalator or the like. When it exists between the handrails, there is a problem that the projected image is blocked and information cannot be projected onto the handrail.
In particular, when using the display device in Patent Document 2 that does not require remodeling work on the escalator body and its surroundings, as in the operation display device in Patent Document 1, information is projected from the top onto the escalator boarding / exiting section. Because the whole body of the user becomes a shield and part of the image is blocked by the user's standing position, it is impossible to provide information to the user reliably and safety in using the escalator It cannot contribute to improvement.

[1. Description of configuration]
Hereinafter, an information providing system according to an embodiment of the present invention will be described in detail with reference to the drawings. However, the scope of the invention is not limited to the illustrated examples.

(Embodiment)
The configuration of the information providing system according to the embodiment of the present invention will be described with reference to FIG. FIG. 1 is a block diagram showing an example of the configuration of the information providing system.
As shown in FIG. 1, an information providing system 100 (hereinafter simply referred to as a system 100) in an escalator includes a control device 1, two projection devices 2 and 3, a driving direction detection device 4, and a moving speed detection device 5. .

  The control device 1 is a device that can be programmed arbitrarily such as a general-purpose computer or a PLC (programmable logic controller) and can control other devices, and a storage unit (not shown) in the control device 1. The information (provided information) of the image to be projected stored in advance is read out and output to the projection devices 2 and 3 that are the control targets to project the image.

The projection apparatuses 2 and 3 are ultra-short focus type projectors, and can project an image with a focal length much shorter than the focal length of a conventional projector. For example, while the focal length of a conventional projector is 200 to 300 cm, the focal length of an ultra short focal length projector is an extremely short focal length of about several tens of centimeters.
Then, the projection devices 2 and 3 project the projected image input from the control device 1 onto the projection target.

The driving direction detection device 4 is a device that detects the driving direction of the escalator step. For example, the driving direction detection device 4 is a device that detects the driving direction of the escalator step using a sensor such as an ultrasonic sensor or an optical sensor.
In addition, it is a device that does not physically detect the driving direction of the escalator step using a sensor, but acquires information on the driving direction of the escalator step from a control device (not shown) that controls the entire escalator. There may be.

The moving speed detection device 5 is a device that detects the moving speed of the escalator step. For example, the moving speed detection device 5 is a device that detects the moving speed of the escalator step using a sensor such as an ultrasonic sensor or an optical sensor.
In addition, it is a device that does not physically detect the moving speed of the escalator step using a sensor but acquires information on the moving speed of the escalator step from a control device (not shown) that controls the entire escalator. There may be.

[2. Explanation of operation of information provision system]
The operation of the system 100 installed in the escalator will be described with reference to FIGS.
FIG. 2 is a schematic configuration diagram illustrating an example of an escalator in which the system is installed. FIG. 2A is a schematic configuration diagram in which the escalator is seen from above, and FIG. 2B is a schematic diagram in which the escalator is viewed from the side. FIG. 2C is a schematic configuration diagram of the user as seen from the step side of the escalator.
As shown in FIG. 2, the escalator is provided with a stepped step surface (step ST21) that automatically moves up and down, and handrails BT21 and BT22 that are installed on both sides of step ST21 and move in synchronization with the moving speed of step ST21. I have. Further, a step ST21 is provided with a horizontal getting-on / off portion LD21 at a portion where the step changes from a step shape to a horizontal state.
In FIG. 2, only one end of the escalator (the vicinity of the upper floor getting on and off portion) is shown, but of course, the other end of the escalator (the vicinity of the lower floor getting on and off portion) has the same configuration. There may be.
As shown in FIG. 2, the two ultra-short focus type projection devices 2 and 3 are installed opposite to both ends in the direction perpendicular to the moving direction of step ST21, which is the escalator boarding / exiting portion LD21. The same image IM21, which is the image to be projected (provided information) input by the control of No. 1, is projected onto the getting-on / off unit LD21 from both sides.
In addition, since the installation place in the escalator of the control apparatus 1, the driving | running | working direction detection apparatus 4, and the moving speed detection apparatus 5 which comprises the system 100 can be installed in arbitrary places, the specific illustration in FIG. 2 is abbreviate | omitted.

  Since the two projection devices 2 and 3 are ultra-short focus type projection devices, the user's human body HM21 which is a shield entering between the projection devices 2 and 3 and the getting-on / off unit LD21 is, for example, from the toes to the ankles. It is possible to greatly reduce the image that becomes a part up to and is obstructed.

Further, since the two projection devices 2 and 3 project the same image IM21 onto the boarding / exiting part LD21 from both sides to the boarding / exiting part LD21, the blocked images can be complemented with each other.
For example, FIG. 3 is an explanatory diagram for explaining the state of the projected image, and the image projected from the projection device 2 onto the boarding / exiting unit LD31 is blocked by the user's human body HM31 to generate the image shielding unit SD31. Similarly, the image projected from the projection device 3 onto the boarding / exiting section LD31 is blocked by the user's human body HM31 to generate the image shielding section SD32.
At this time, since the same image is projected from the projection device 3 onto the portion of the image shielding unit SD31, the image of the portion of the image shielding unit SD31 is complemented and is not lost. Similarly, since the same image is projected from the projection device 2 onto the portion of the image shielding unit SD32, the image of the portion of the image shielding unit SD32 is complemented and is not lost.
That is, the two projectors 2 and 3 complement each other in the image shielding units SD31 and SD32 that are blocked by the user's human body HM31, so that part of the image is blocked by the user's standing position. Thus, it is possible to prevent a situation where information cannot be reliably provided to the user.

  In addition, since the same image is projected from the two projection devices 2 and 3 in the portions other than the image shielding portions SD31 and SD32 blocked by the user's human body HM31, the amount of light increases and the image becomes clear. It becomes easier to visually recognize the provided information. Although the image shielding portions SD31 and SD32 have half the light amount as compared with portions other than the image shielding portions SD31 and SD32, the areas of the image shielding portions SD31 and SD32 are the same as those of the ultrashort focus type projection devices 2 and 3. Since it can be made small by using, the influence with respect to the visibility of the information provided becomes very small.

  In this way, the two ultra-short focus type projectors 2 and 3 are installed opposite to both ends in the direction perpendicular to the moving direction of step ST21, which is an escalator boarding / alighting unit, and input from the control device 1 By projecting the same video onto the boarding / exiting section LD21, it is possible to compensate for the lack of video due to the user's standing position, and therefore it is possible to provide information on the escalator regardless of the user's standing position.

Further, in the system 100, the control device 1 causes the projection devices 2 and 3 to project an image whose direction is set in accordance with the driving direction detected by the driving direction detection device 4 onto the escalator landing part LD21. For example, an image obtained by rotating the direction of the image to be projected according to the detected driving direction by 180 degrees is projected from the projection devices 2 and 3 onto the escalator LD21.
In this way, by projecting the image IM21 whose direction is set in accordance with the driving direction detected by the driving direction detection device 4 from the projection devices 2 and 3 onto the getting-on / off unit LD21 of the escalator, the getting-on / off unit LD21 sees the user. It is possible to prevent the projected image IM21 from being reversed.

  Further, in the system 100, the control device 1 transmits, from the projection devices 2 and 3, a moving image synchronized with the moving speed in step ST 21 detected by the moving speed detecting device 5 based on the driving direction detected by the driving direction detecting device 4. Project onto the escalator boarding part LD21. For example, the image IM21 obtained by moving the image to be projected in the driving direction in synchronism with the detected moving speed is projected from the projection devices 2 and 3 onto the escalator LD21.

  In this way, based on the driving direction detected by the driving direction detection device 4, an image that moves in synchronization with the moving speed detected by the moving speed detection device 5 is projected from the projection devices 2 and 3 onto the escalator LD 21. Thus, the image IM21 projected onto the boarding / exiting portion LD21 as viewed from the user moves in synchronization with the moving speed, so that the user can visually recognize the same image IM21 while moving.

  As described above, in the information providing system in the escalator, the two ultra-short focus type projectors 2 and 3 are installed opposite to both ends of the escalator LD 21 and in the direction orthogonal to the moving direction of step ST21. In addition, by projecting the same image IM21 input from the control device 1 onto the boarding / exiting section LD21, it is possible to compensate for the lack of images due to the user's standing position. Information can be provided.

  Further, by projecting an image whose direction is set in accordance with the driving direction detected by the driving direction detection device 4 from the projection devices 2 and 3 onto the getting on / off portion LD21 of the escalator, it is projected onto the getting on / off portion LD21 as seen from the user. It is possible to prevent the video IM21 from being reversed.

  Furthermore, based on the driving direction detected by the driving direction detection device 4, an image that moves in synchronization with the moving speed of step ST 21 detected by the moving speed detection device 5 is projected from the projection devices 2 and 3 onto the escalator landing part LD 21. As a result, the image IM21 projected onto the boarding / exiting portion LD21 as viewed from the user moves in synchronization with the moving speed, so that the user can view the same image IM21 while moving.

(Second Embodiment)
In the description of the embodiment of the present invention, the image of the information to be provided on the escalator boarding / exiting part is projected, but the image of the information to be provided is also projected on the outer deck arranged outside the handrail of the escalator. May be.
FIG. 4 is a configuration block diagram illustrating an example of the configuration of the information providing system according to the second embodiment. In addition, description of the same part as the information provision system which concerns on above-mentioned embodiment is abbreviate | omitted suitably.

A plurality of projecting means for projecting an image across the entire outer deck by projecting an image from the upper side, which is provided above the outer deck disposed on the outside of the handrail of the escalator; It has a projection device 6 configured.

FIG. 5 is a schematic configuration diagram illustrating an example of an escalator in which the system according to the second embodiment is installed. FIG. 5A is a schematic configuration diagram when the escalator is viewed from the side, and FIG. It is the schematic block diagram which looked down at the escalator from upper direction.
The escalator includes a stepped step surface (step ST51) that moves up and down automatically, and handrails BT51 and BT52 that are installed on both sides of step ST51 and move in synchronization with the moving speed of step ST51. In addition, the step ST51 is provided with horizontal getting-on / off portions LD51 and LD52 at the portion where the step changes from the step shape to the horizontal state. Further, outside decks DE51 and DE52 are provided outside the handrails BT51 and BT52.

As shown in FIG. 5, the plurality of projection means PJ61 to PJ66 constituting the projection device 6 are arranged above the escalator outer decks DE51 and DE52 at a predetermined interval, and the plurality of projection means PJ61 to PJ66 are respectively the outer decks DE51. And by projecting images onto DE 52, the images IM51 and IM52 are projected over the entire outer decks DE51 and DE52.
In addition, since the installation place in the escalator of the control apparatus 1, the driving | running | working direction detection apparatus 4, and the moving speed detection apparatus 5 which comprises the system 200 can be installed in arbitrary places, specific illustration in FIG. 5 is abbreviate | omitted.

As shown in FIG. 5, in the information providing system in the escalator, by installing the projection device 6 composed of a plurality of projection means PJ61 to PJ66 above the escalator outer decks DE51 and DE52, the escalator outer deck DE51. Since the images IM51 and IM52 can be projected over the entire outer decks DE51 and DE52 from above the DE52, the video IM51 is displayed on the entire outer decks DE51 and DE52 even when the user is on the escalator step ST51. And IM52 can be projected to provide information on the escalator.
Further, since there is a low possibility that a shielding object such as a human body enters between the outer decks DE51 and DE52 and the projection device 6 (projection means PJ61 to PJ66), there is little possibility that the image is shielded and lost.

Further, in the system 200, the control device 1 sends an image whose direction is set in accordance with the driving direction detected by the driving direction detection device 4 from the projection device 6 to the outer decks DE51 and DE52 arranged outside the handrail of the escalator. Project. For example, an image obtained by rotating the direction of the image to be projected by 180 degrees in accordance with the detected driving direction is projected from the projection device 6 onto the outer decks DE51 and DE52 of the escalator.
In this way, by projecting the images IM51 and IM52 whose directions are set in accordance with the driving direction detected by the driving direction detection device 4 from the projection device 6 onto the outer decks DE51 and DE52 of the escalator, the outer decks are viewed from the user. It is possible to prevent the images IM51 and IM52 projected on the DE51 and DE52 from being reversed.

  Further, in the system 200, the control device 1 projects the images IM51 and IM52 that move in synchronization with the moving speed of step ST51 detected by the moving speed detecting device 5 based on the driving direction detected by the driving direction detecting device 4. 6 is projected onto the outer decks DE51 and DE52 of the escalator.

  As described above, based on the driving direction detected by the driving direction detecting device 4, the video moving in synchronization with the moving speed of step ST 51 detected by the moving speed detecting device 5 is transferred from the projection device 6 to the outer decks DE 51 and DE 52 of the escalator. By projecting, the images IM51 and IM52 projected on the outer decks DE51 and DE52 move in synchronization with the moving speed, so that the user can visually recognize the same images IM51 and IM52 on the outer decks DE51 and DE52 while moving. Can do.

  As described above, in the information providing system in the escalator, by installing the projection device 6 composed of the plurality of projection means PJ61 to PJ66 above the outer decks DE51 and DE52 arranged outside the handrail of the escalator. Since the image can be projected from the upper side of the outer decks DE51 and DE52 of the escalator to the entire outer decks DE51 and DE52 without being shielded by a human body or the like, the user gets on the step ST51 of the escalator. Sometimes, it is possible to provide information on the escalator by projecting images on the entire outer decks DE51 and DE52.

  Further, by projecting the images IM51 and IM52 whose directions are set in accordance with the driving direction detected by the driving direction detection device 4 from the projection device 6 onto the outer decks DE51 and DE52 of the escalator, the outer decks DE51 and DE52 as viewed from the user are displayed. It is possible to prevent the images IM51 and IM52 projected on the DE 52 from being reversed.

  Further, based on the driving direction detected by the driving direction detection device 4, an image moving in synchronization with the moving speed of step ST 51 detected by the moving speed detection device 5 is projected from the projection device 6 to the outer decks DE 51 and DE 52 of the escalator. As a result, the images IM51 and IM52 projected on the outer decks DE51 and DE52 move in synchronization with the moving speed, so that the user can visually recognize the same images IM51 and IM52 on the outer decks DE51 and DE52 while moving. .

In the description of the embodiment of the present invention, the image of the information to be provided is projected on the escalator boarding / exiting part or the outer deck. Depending on the material of the boarding / exiting part or the outer deck, the reflectance of the surface is projected. May be expensive. If the projection surface of the image has a high reflectance, the image may become unclear and difficult to see, so the surface of the boarding / alighting part or the outer deck is painted to reduce the reflectance of the surface. Also good.
In this way, the projected image becomes clear by applying the coating for reducing the reflectance of the surface on the surface of the escalator or on the surface of the outer deck. Can be improved.
