Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a traffic signal for pedestrians, and more particularly to a traffic signal for pedestrians in which a picture of a pedestrian or the like is displayed as a traversable state.
[0002]
[Prior art]
Conventionally, a traffic signal for pedestrians arranges a light bulb inside the traffic light, displays a picture shaped like a pedestrian on a separate light emitting surface colored red and blue, and lights the light bulb inside.・ Blinks to indicate the traversable state and traversing prohibited state.
[0003]
[Problems to be solved by the present invention]
However, with a conventional pedestrian traffic light, for an infant who does not know the meaning of a color, it is not clear what the displayed color means. In addition, a person with abnormal color vision can only visually recognize light and dark information consisting of black and white without color, and thus may not be able to determine the display state. In addition, even a person with relatively mild color vision deficiency may not be able to understand the color accurately, and there has been a concern that the person may be erroneously recognized.
[0004]
Also, in the conventional pedestrian traffic signal, the display state is changed by turning on or off the internal light bulb, but since the pattern on the light emitting surface does not change at all, there is no impact, and attention of the pedestrian is taken. It was difficult to collect. Furthermore, in order to make the display state of the signal easy to understand, it is necessary to make the display portion as large as possible. Are provided separately, and the entire size is restricted, so that it is difficult to enlarge each light emitting surface.
[0005]
Accordingly, the present invention provides a pedestrian traffic signal that allows more people to understand the display state.
[0006]
[Means for Solving the Problems]
The traffic signal for pedestrians according to the first aspect of the present invention corresponds to a casing having a light-emitting surface on the front surface, light-emitting means provided in the casing, and a mode of light emitted from the light-emitting surface corresponding to a picture. A pattern area to be displayed and a background area serving as the background of the pattern, and a pattern display means for displaying the pattern on the light emitting surface, and a moving image for dynamically changing the pattern displayed by the pattern display means. Display control means.
[0007]
Here, an example of the "light emitting means" is an LED (light emitting diode).
[0008]
Therefore, according to the pedestrian traffic signal of the first aspect of the present invention, the picture area is made different from the background area which is the background of the picture area by the light of the light emitting means provided in the casing. On the light emitting surface. Also, the moving image display control means dynamically changes the pattern area over time to display the pattern dynamically.

A pedestrian traffic signal according to a second aspect of the present invention is the pedestrian traffic signal according to the first aspect, wherein the light emitting means has at least a blue light emitting portion, and the picture display means is provided in the background area. Alternatively, blue light is emitted to any one of the picture regions.
[0010]
Therefore, according to the pedestrian traffic signal of the invention of claim 2, in addition to the operation of the pedestrian traffic signal of claim 1, the picture display means uses, for example, a light-emitting diode to display the background area or the picture area. Blue light is emitted in either one of the regions. Thereby, the meaning of the dynamically displayed picture coincides with the blue light emission display indicating the traversable state, which makes it difficult to recognize the pattern by mistake.
[0011]
A traffic light for pedestrians according to a third aspect of the present invention is the traffic light for pedestrians according to the first or second aspect of the present invention.

The light emitting surface is constituted by the same light emitting surface.
[0014]
Therefore, according to the pedestrian traffic signal of the invention of claim 4, in addition to the operation of the pedestrian traffic signal of claim 3, the crossing enabled state and the crossing prohibited state are alternately performed on one light emitting surface. Since the display is performed, the size of the light emitting surface can be increased without changing the size of the entire traffic light.
[0015]

Means, and a remaining time display means for displaying, on the light emitting surface, a numeral or a symbol relating to the remaining time calculated by the remaining time calculation means.
[0016]
Therefore, according to the pedestrian traffic signal of the invention of claim 5, in addition to the operation of the pedestrian traffic signal of claim 3 or 4, in the crossing prohibited state, the remaining time until the traversable state is reached. The time is calculated, and the remaining time is displayed on the light emitting surface using numbers or symbols. This allows the traverser to recognize the waiting time.
[0017]

The apparatus further includes a remaining time calculating means for calculating, and a remaining time displaying means for displaying, on the light emitting surface, a numeral or a symbol relating to the remaining time calculated by the remaining time calculating means.
[0018]
Therefore, according to the pedestrian traffic signal of the invention of claim 6, in addition to the operation of the pedestrian traffic signal of any one of claims 3 to 5, in the traversable state, the traversing prohibited state is set. Is calculated, and the remaining time is displayed on the light-emitting surface using numbers or symbols. This makes it possible for the traverser to recognize the traversable time.
[0019]
The traffic light for pedestrians according to the invention of claim 7 is the traffic light for pedestrians according to claim 5 or 6, wherein the light-emitting surface is a traversable area that displays a picture in a traversable state; A cross-prohibition area for displaying a pattern in a prohibited state, wherein the remaining time display means is configured to control the remaining time with respect to an area of the crossable area or the cross-prohibition area that is opposite to a side on which a pattern is displayed. Is to display a number or a symbol related to it.
[0020]
Therefore, according to the pedestrian traffic signal of the invention of claim 7, in addition to the operation of the pedestrian traffic signal of claim 5 or claim 6, in the traversable state, the picture is dynamic in the traversable area. And the remaining time is displayed in the crossing prohibited area (the area where the picture is displayed in the crossing prohibited state). On the other hand, in the crossing prohibited state, the picture is displayed stationary in the crossing prohibited area, and the remaining time is displayed in the crossable area. That is, the remaining time is displayed by using the area of the side which is not used originally (that is, the side where the light emission is not displayed).
[0021]
The traffic light for pedestrians according to the invention of claim 8 is the traffic light for pedestrians according to any one of claims 1 to 7, wherein the light emitting means is arranged in a grid pattern with respect to the light emitting surface.

[0024]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a traffic light 1 for pedestrians according to a first embodiment of the present invention will be described with reference to FIGS. FIG. 1A is a perspective view showing a configuration of a pedestrian traffic signal 1, and FIG. 1B is a plan view thereof. FIG. 2 is an exploded perspective view showing the configuration of the pedestrian traffic signal 1. FIG. 3 is a longitudinal sectional view showing an internal configuration of the pedestrian traffic signal 1. FIG. 4 is a flowchart showing the display operation of the pedestrian traffic light 1. FIG. 5 is a block diagram showing a functional configuration of the traffic signal 1 for pedestrians. FIG. 6 is an explanatory diagram showing display contents on the light emitting surface.
[0025]
The traffic signal 1 for pedestrians of this embodiment is used for traffic control of pedestrians on a road with a pedestrian crossing. As shown in FIGS. 1 to 3, a casing 2 constituting an outer shape of the pedestrian traffic light 1 is formed of, for example, a metal plate. The casing 2 is divided into a front part 3 and a rear part 4, and has a connection port 13 on the upper surface of the rear part 4. One side of the front part 3 and the rear part 4 of the casing 2 are rotatably connected via a hinge 9b, and the other side is fixed to each other via a lock 9a. The casing 2 includes a protection panel 6, a substrate 10 on which the light emitting means 8 is disposed, a control device 11, a bonding plate 12, and the like.
[0026]
The protection panel 6 is disposed in the front opening 7 of the casing 2 and protects the light emitting means 8 and the like from wind and rain or the like which may cause a failure of the pedestrian traffic signal 1. The protection panel 6 is made of a transparent or translucent member, and the light of the light emitting means 8 is radiated to the outside through the protection panel 6. That is, the front surface of the protection panel 6 corresponds to the light emitting surface of the present invention. When the protection panel 6 is formed of a translucent member, the light passing therethrough can be diffused, and the outline of the light emitting means 8 can be made ambiguous. That is, the outline of the picture displayed by the light emitting means 8 can be made to look smooth.
[0027]
The light emitting means 8 is composed of a plurality of light emitting diodes that emit visible light by applying a forward bias voltage to a PN junction of a semiconductor. In the present embodiment, in particular, in the present embodiment, three primary colors (R (red), G ( (Green) and B (blue)) are incorporated in one shell-type element. That is, the light emitting means 8 is composed of a plurality of full-color light emitting diodes capable of expressing various colors by emitting light by combining these. The features of the light emitting diode include power saving, space saving, and long service life. By using these for the pedestrian traffic signal 1, it is excellent in maintainability. In addition, since it has the features of high luminous intensity, high light output, and wide viewing angle, it is possible to make more traversers recognize the display state.
[0028]
Mounting holes (not shown) for fixing the electrode terminals of the light emitting means 8 are provided on the substrate 10 in a lattice shape, and the light emitting means 8 is fitted into these mounting holes. Therefore, uniform light can be emitted from the entire light emitting surface, and the pattern area and the background area can be visually distinguished by changing the light emission mode of each light emitting means 8.
[0029]
As shown in FIG. 3, the bonding plate 12 is for fixing the board 10 incorporated in the casing 2 and the control device 11 together to the mounting portion 14 of the rear portion 4 of the casing 2. As a result, a plurality of items contained in the casing 2 are unitized. For this reason, when performing maintenance of the traffic signal 1 for pedestrians, the work of installation and removal can be simplified.
[0030]
The connection port 13 is connected to an electric pole or an arm extending from a support pole, and is provided to take in a cord for a commercial power supply for supplying electric power into the casing 2.
[0031]
As shown in FIG. 5, the control device 11 includes a moving image display control unit 17 and a remaining time calculation unit 15 that are controlled based on an external control signal 23 as a functional configuration. The moving image display control unit 17 individually controls the plurality of light emitting units 8 via the picture display unit 21, and includes a switching control unit 18, a traversable state control unit 19, and a traverse having a remaining time display unit 16. And a prohibition state control unit 20.
[0032]
Here, the traversable state control unit 19 displays the traversable state, and causes the light emitting means 8 corresponding to the background area to emit blue light and the light emitting means 8 corresponding to the picture area to emit yellow light. Further, the picture is dynamically displayed by changing the picture area over time according to the picture. The crossing prohibited state control unit 20 displays the crossing prohibited state, and causes the light emitting unit 8 corresponding to the background area to emit red light and the light emitting unit 8 corresponding to the picture area to emit yellow light. It should be noted that the picture in the crossing prohibited state is kept constant without changing. However, the crossing prohibition state control unit 20 is provided with the remaining time display means 16, and the remaining time until the state changes from the crossing prohibition state to the crossable state is displayed by the light emitting means 8 by a number. I have. The switching control unit 18 switches between a traversable state and a traversing prohibited state, and selects one of the traversing possible state control unit 19 and the traversing prohibited state control unit 20 based on the external control signal 23. Note that the external control signal 23 is a signal output from a control unit housed in a control panel (not shown) for interlocking with the vehicle signal. Has been entered.
[0033]
On the other hand, the remaining time calculating means 15 includes a timer T for measuring the remaining time (that is, the waiting time) in the crossing prohibited state, receives the signal of the external control signal 23, and starts measuring time. The remaining time measured by the remaining time calculation means 15 is output to the remaining time display means 16 of the crossing prohibited state control unit 20.
[0034]
The picture changing means is previously stored in the picture displaying means 21 in advance, and the plurality of light emitting means 8 are divided into the light emitting means 8 for the area corresponding to the picture and the light emitting means 8 for the background area. This enables different display modes. That is, the plurality of light emitting units 8 are individually controlled based on the output of the moving image display control unit 17.
[0035]
Next, the operation of the pedestrian traffic light 1 of the embodiment will be described based on the flowchart of FIG. 4, the block diagram of FIG. 5, and the explanatory diagram of FIG. First, it is determined whether or not the external control signal 23 input to the switching control unit 18 instructs switching to the traversable state. If there is an instruction to switch to the traversable state (YES in step S1), the picture display means 21 causes the light emitting means 8 corresponding to the background area to emit blue light (step S2) and the light emitting means corresponding to the picture area. 8 is caused to emit yellow light (step S3). Then, the picture is dynamically displayed by changing the light emitting means 8 corresponding to the picture area corresponding to the picture, that is, the picture area with time (step S4). In other words, as shown in FIGS. 6A to 6C, a pattern 24 corresponding to the pattern area 24 (a pattern 24 indicating a crossing state) is dynamically displayed with respect to the background area 25 so that the current pattern is displayed. It is possible to notify the traverser that the state is a state in which walking is possible.
[0036]
Thereafter, when the blinking display is instructed by the external control signal 23 in the traversable state (YES in step S5), the light emitting means 8 corresponding to the background area is blinked (step S6), and the picture area is temporally changed. The change is stopped (step S7). The meaning of the blinking display state is to guide the traverser safely and reliably to the traversing prohibited state when shifting from the traversable state to the traversing prohibited state. Thus, it is possible to suppress dangerous crossing such as running into a pedestrian crossing after the blinking display state.
[0037]
If there is an instruction from the external control signal 23 to shift to the crossing prohibited state (YES in step S8), time measurement is started by the timer T of the remaining time calculation means 15 (step S9), and the state shifts to the crossing prohibited state. That is, in the crossing prohibited state, the light emitting means 8 corresponding to the background area emits red light (step S10), and the light emitting means 8 corresponding to the picture area continuously emits yellow light. In this case, as shown in FIG. 6D, the picture area 24 is kept in a constant state without being changed (step S11). While the timer T of the remaining time calculating means 15 is counting the time, the light emitting means 8 displays the remaining time with numeral 26 (step S12). As a result, the numeral 26 that counts down is displayed on a part of the light emitting surface. Since the remaining time is directly indicated by numeral 26, the remaining time can be accurately notified. That is, it is possible to eliminate the ambiguity of the waiting time in the crossing prohibited state, and to provide a standard for doing other things. Thereafter, when an instruction to move to the traversable state is given by the external control signal 23 (YES in step S13), the process proceeds to step S2, and the display operation is repeated.
[0038]
As described above, the pedestrian traffic signal 1 of the present example displays a picture by changing the mode of light between the picture area 24 and the background area 25, and changes the picture area 24 over time to change the picture. Is dynamically displayed, so that the amount of information given to the traverser can be increased, and it is possible to clearly recognize what action the picture means. In other words, even an infant or a person with abnormal color vision who does not understand the meaning of the color can reliably recognize the crossable state by the dynamic display of the picture. In addition, the dynamic display of the picture can give an impact to the traversal and draw attention. In particular, only the pattern displayed when the traversing is possible is dynamically displayed, and the pattern is stopped when the traversing is prohibited, so that the distinction between the traversing possible state and the traversing prohibited state is clearly recognized, and the wrong recognition is ensured. Can be prevented.
[0039]
Further, in the pedestrian traffic signal 1 of this example, the traversable state of the blue light emitting surface and the crossing prohibited state of the red light emitting surface are displayed on the same plane. The light emitting surface can be enlarged. Therefore, the visibility is improved, and the safety of the crosser can be further enhanced.
[0040]
In addition, the traffic light 1 for pedestrians of the present example can perform another operation for the person waiting for the change of the display state because the remaining time until the change to the traversable state is visible. Can give an indication of. In particular, since the remaining time is displayed on the light-emitting surface of the pedestrian traffic signal 1, it can be configured at a lower cost than when a remaining time display device is separately provided. In addition, it is possible to prevent a mistake with a similar object near the pedestrian traffic signal 1, for example, a luminous body such as a neon light of a pachinko parlor.
[0041]
Furthermore, since the pedestrian traffic signal 1 of this example has a plurality of light emitting means 8 arranged in a grid, light can be uniformly emitted from the light emitting surface, and the light emitting means 8 is to be expressed. The picture can be displayed more faithfully. In particular, in this example, since the light emitting diodes are employed as the respective light emitting means 8, the power consumption can be reduced, and the influence on the environment can be reduced. In addition, since it has a long life, maintenance costs can be reduced.
[0042]
Next, a pedestrian traffic signal 30 according to a second embodiment of the present invention will be described with reference to FIG. FIGS. 7A and 7B are explanatory diagrams showing the configuration and display state of the pedestrian traffic signal 30. FIG. 7A shows a crossing prohibited state, and FIG. 7B shows a crossable state.
[0043]
The pedestrian traffic signal 30 includes a casing 31 having the same appearance as a conventionally-known traffic signal, and has a cross-prohibited area 32 in which a picture is displayed in a cross-prohibited state and a cross-prohibited state on the front surface. Has a light-emitting surface 34 partitioned into a crossable area 33 in which a picture is displayed. The configuration inside the casing 31, that is, the configuration for emitting light from the light emitting surface 34 is the same as that of the first embodiment, and a detailed description is omitted here.
[0044]
Further, the pedestrian traffic signal 30 has a remaining time calculating means 15 and a remaining time displaying means 16 as in the first embodiment (see FIG. 5). Calculates the remaining time (that is, the traversable time) even in the traversable state, and the remaining time display means 16 displays the remaining time in the traversable state.
[0045]
The display mode on the pedestrian traffic signal 30 will be specifically described. As shown in FIG. 7A, in the crossing prohibited state, the pattern 35 is stopped and displayed in the upper crossing prohibited area 32. The light emitting means 8 corresponding to the picture area emits yellow light, and the light emitting means 8 corresponding to the background area 36 emits red light. At this time, the remaining time (waiting time) calculated by the remaining time calculating means 15 is displayed as a numeral 37 in the lower traversable area 33 without displaying a picture. That is, only the light emitting means 8 corresponding to the numeral 37 emits red light, so that the red numeral 37 is displayed.
[0046]
On the other hand, as shown in FIG. 7B, in the traversable state, the picture area is changed over time so that the picture 38 is dynamically displayed in the lower traversable area 33, and the picture area is changed. The corresponding light emitting means 8 emits yellow light, and the light emitting means 8 corresponding to the background area emits blue light. At this time, the remaining time (the traversable time) calculated by the remaining time calculating means 15 is displayed as a numeral 39 in the upper crossing prohibited area 31 without displaying the picture. That is, only the light emitting means 8 corresponding to the numeral 39 emits blue light, so that the blue numeral 39 is displayed.
[0047]
As described above, in addition to the effect of the pedestrian traffic signal 1 of the first embodiment, the pedestrian traffic signal 30 of the present example can visually recognize the remaining time until the state changes to the crossing prohibited state. The traversable time becomes clear. For this reason, it is possible to give a sense of security to the traversal and to suppress a dangerous traversal start (run in) when the remaining time is short. In addition, the driver of the vehicle traveling on the roadway can be used as an indication of the waiting time, so that the stress of the driver and the like due to the waiting time can be eliminated.
[0048]
The pedestrian traffic signal 30 of the present example displays the remaining time (waiting time) using the traversable area 33 in the traversing prohibited state, and uses the traversing prohibited area 32 in the traversing possible state. Since the remaining time (crossable time) is displayed, it is possible to display a large picture or number indicating the remaining time without changing the size of the conventional traffic light. Therefore, the visibility and the convenience and safety by recognizing the remaining time can be improved.
[0049]
As described above, the present invention has been described with reference to two preferred embodiments. However, the present invention is not limited to these embodiments, and various forms are provided without departing from the gist of the present invention as described below. Improvements and design changes are possible.
[0050]
For example, the following can be exemplified as a display method of the remaining time other than the above in the crossing prohibited state. That is, in the example shown in FIG. 8A, in a crossing prohibited state, a human-shaped pattern 40 is displayed, and the light emitting means 8 indicating the pattern 40 is gradually turned off with the passage of time. Things. In other words, the yellow light emitting portion is gradually reduced according to the remaining time while the border of the picture 40 is left by holding the picture area. According to this display method, the number of components of the picture 40 for displaying the remaining time is reduced, and the light emitting surface is not complicated and the light emitting surface is easy to recognize.
[0051]
In the example shown in FIG. 8B, in the crossing prohibited state, the bar-shaped pattern 41 for displaying the remaining time is given priority over the pattern 40 and is displayed in a different luminescent color. Specifically, a plurality of strip-shaped pictures having different lengths are displayed, and the number of the displayed pictures 41 is reduced over time. According to this display method, it is possible to display and show the band-shaped pattern 41 in front of the light-emitting surface when viewed from the crosser, so that the pattern 40 and the pattern 41 can be easily distinguished.
[0052]
In the above two embodiments, the case where a light emitting diode is used as the light emitting means 8 has been described, but for example, a liquid crystal display may be used. The structure of the liquid crystal display includes two glass substrates, a liquid crystal layer interposed between the glass substrates, and a backlight disposed on the back side of the glass substrates. As a method of emitting light, when a voltage is applied to the liquid crystal layer, the light emitted from the backlight emits light when the longitudinal direction of the rod-like molecules in the liquid crystal is oriented perpendicular to the glass substrate. To emit light to the light emitting surface. That is, by controlling the transmission of light by the liquid crystal, the display modes in the picture region and the background region are made different from each other.
[0053]
In the two embodiments, as a method of dynamically displaying a human-shaped picture, a method realized by mainly moving a hand and a foot at substantially the center of the light emitting surface has been described. You may make it display dynamically using the whole light emitting surface so that it may scroll from one end of a light emitting surface to the other end.
[0054]
In the first embodiment, in the blinking display state during the transition from the traversable state to the traversing prohibited state, the pattern is stopped, but the pattern is dynamically moved with a slower movement than the traversable state. It can also be displayed. Further, in the second embodiment, since the remaining time is displayed in the traversable state, the state may be shifted from the traversable state to the traversing prohibited state without passing through the blinking display state.
[0055]
Further, in the above-described two embodiments, the display state is switched by the external control signal 23, but the push button 22 is provided as shown by a two-dot chain line in FIG. When an operation is performed, the state may be shifted to a crossable state after a lapse of a predetermined time from the operation.
[0056]
【The invention's effect】

That is, the safety of the crosser can be greatly improved. In addition, since the design is moving, the pedestrian can be impacted and attracted attention.
[0057]
The traffic signal for pedestrians according to the second aspect of the present invention is, in addition to the effect of the first aspect, capable of emitting blue light to one of the background area and the picture area so that a person who does not understand the meaning of the color can be used. , It can be understood that blue indicates a crossable state. In addition, a person who knows the meaning of the color does not feel unnatural in the display state because the meaning of the recognized color matches the meaning of the movement of the picture.
[0058]
In the traffic light for pedestrians according to the third aspect of the present invention, in addition to the effects of the first or second aspect of the present invention, the pattern does not move when the red light is emitted, so that the distinction between the crossable state and the cross prohibited state is clearly made.

[0060]
According to the pedestrian traffic signal of the invention of claim 5, in addition to the effect of the invention of claim 3 or 4, the waiting time becomes clear because the remaining time until the state changes to a crossable state becomes visible. Thus, the stress of the traverser due to the waiting time can be suppressed, and the standard for performing other operations can be given. In particular, since the remaining time is displayed on the light-emitting surface, it can be configured at a lower cost than when a time display device is separately provided, and can be mistaken for other similar objects, for example, a light-emitting body such as a neon light of a pachinko parlor. Can be prevented.

That is, the safety of the crosser can be further improved.
[0062]
According to the pedestrian traffic signal of the invention of claim 7, in addition to the effect of the invention of claim 5 or 6, the remaining time is displayed by using the area on the opposite side which is not originally used. The pattern and the number indicating the remaining time can be displayed large without changing the size of. For this reason, the visibility and the convenience and safety by recognizing the remaining time can be improved.
[0063]
The traffic light for pedestrians according to the invention of claim 8 has, in addition to the effects of any one of the inventions of claims 1 to 7, an arrangement in which a plurality of light-emitting portions are arranged in a grid so that light is uniformly emitted from the light-emitting surface. And the picture to be expressed by the light emitting means can be displayed more faithfully.
[0064]
