Description

A luminous braille sidewalk block

The present invention relates to a braille sidewalk block installed along a crosswalk entry line or a subway waiting line in India to provide a projection pattern for a visually impaired person and is provided with an external signal such as a signal lamp or a subway guide plate, The present invention relates to a light emitting type Braille sidewalk block system through photovoltaic power generation, in which more accurate information is transmitted through a predetermined light emitting function and a discrimination power is greatly improved.

Generally, the 'sidewalk block' is a block-shaped building material installed along the Indian (human) road and providing the floor for pedestrians. A protrusion pattern is given to specify a case where a display function of the position and the direction is added.

In other words, a braille sidewalk block, also referred to as a sidewalk sidewalk block, is a special purpose sidewalk that is provided with a predetermined projection pattern on its surface so that the position and direction of the sidewalk of the visually impaired can be detected by the touch of the sole As a block, strictly speaking, it distinguishes between a braille projection for position indication and a linear projection for direction display, but is usually called a projection pattern. Such a braille block is mainly installed along the entrance line of a pedestrian crossing or a subway waiting line A walking point, a waiting point, a starting point, and an end point.

Therefore, the protruding pattern of the braille sidewalk block includes braille protrusions and linear protrusions, which will be used consistently in this specification.

On the other hand, the size and the material of the braille sidewalk block can be variously changed according to the purpose, but the hexahedron type of 30 cm (width) × 30 cm (length) × 6 cm (height) is most widely used, and the materials include concrete, (So-called "plascon") wrapped in high-strength plastic on the surface of concrete, and a kind of a plate with a protrusion pattern of synthetic resin or metal on the surface of the metal body.

However, the conventional braille sidewalk block has a disadvantage that the identification power is low and the information transfer power is low.

In other words, as the construction of the Braille Braille block is increased, it is recognized as a kind of safety line not only for the visually impaired but also for the general people including the low vision, the elderly and the child. However, since the general braille walk block displays the information with a simple protrusion pattern, This can be useless to users who do not know how to blink or display. Accordingly, even though the braille sidewalk block or the projection pattern is painted in a color having high visibility such as yellow, the user often does not recognize unless the user is walking on a particular circumference, and the discrimination power remarkably deteriorates at night.

In addition, the general braille sidewalk block indicates that the corresponding point is a walking junction, a waiting point, a starting point, and an ending point, but it is impossible to transmit additional information such as a lighting state of a traffic light or entry of a subway. Therefore, a braille sidewalk block capable of clearly displaying various additional information with high discrimination power is urgently required.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a braille sidewalk block capable of clearly displaying additional information that is high in discrimination power and helpful to a user.

For this purpose, the present invention relates to a braille sidewalk block installed along a crosswalk entrance line or a subway waiting line in India to provide a projection pattern for a visually impaired person, and more particularly, To provide a low-power, light-emitting Braille sidewalk block with solar light that shows much more information and greatly improved discrimination power.

According to an aspect of the present invention, there is provided a method of driving a display device including a coupling unit physically coupled to a cable of an external system to which a predetermined driving signal is applied to generate a tuning signal coupled to the driving signal; A braille sidewalk block installed on the floor such that a light source for emitting light is formed and a protrusion pattern of a permeable material through which light generated from the light source is transmitted is formed along one surface and the one surface is exposed to the outside; And a control unit having a photovoltaic generator and a battery and electrically connected to the coupling unit and the light source to selectively apply charging power of the battery to the light source in accordance with the coupling signal, Section provides a light emitting braille sidewalk block system in close contact along the outer surface of the cable and a clip of a metallic material with coils embedded therein.

The luminescent braille sidewalk block system according to the present invention has the advantage of increasing the discrimination power of the braille sidewalk block and displaying various additional information more clearly. That is, according to the present invention, a user can more clearly identify a braille sidewalk block through light as well as touch, and can know the operation status of a traffic light and the entry of a subway through on / off of lights.

In addition, according to the present invention, it is possible to perform a light emitting function in conjunction with an external system such as a traffic light or a subway display panel, and in particular, the coupling portion can be easily installed without any additional electric wiring work.

1 is a perspective view of a braille sidewalk block according to the present invention;

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of a light-emitting braille sagging block system according to the present invention, and can be divided into a coupling part 10, a control part 20, and at least one braille sidewalk block 30 for convenience.

Each of them will be described in detail as follows.

First, the coupling unit 10 is physically coupled to a cable of an external system to which a predetermined driving signal is applied, and generates a tuning signal coupled to a driving signal flowing along the cable.

In this case, the external system may be a traffic light, a subway information signboard, etc., and the pedestrian traffic light optionally switches the green and red lights with a predetermined size driving signal applied through a dedicated cable, A character is displayed with a drive signal of a predetermined size to notify the entry of the subway.

Therefore, driving signals flowing along the respective cables when driving the signal lamp or the subway guide panel necessarily change, so that the coupling unit 10 is physically coupled to the cable of the external system to which the driving signal is applied, And generates a tuning signal coupled to the magnitude variation of the driving signal

Next, the braille sidewalk block 30 is a block-shaped building material installed along the entrance line of a pedestrian crossing or a subway waiting line to provide a floor for a pedestrian, Or a linear protrusion pattern is formed.

At this time, the braille sidewalk block 30 may exhibit a similar appearance to the general one, but in the case of the present invention, a separate light source is embedded in particular so that the light generated from the light source is projected to the outside through the projection pattern, A plurality of wires are connected in series and / or in parallel using wires.

Finally, the control unit 20 controls the light emission of the braille sway block 30 based on the tuning signal of the coupling unit 10.

The control unit 20 includes a solar power generation unit and a battery. The control unit 20 performs a predetermined operation to turn on / off the charging power of the battery to the braille sway block 30 according to the tuning signal of the coupling unit 10 Means.

As a result, the illuminated braille sidewalk block system according to the present invention can improve the discrimination power of the braille sidewalk block 30 and display additional information helpful to the user.
