The present invention relates to a walking guide block for a visually impaired person and a method of manufacturing the same. More particularly, the present invention relates to a walking guide block for a visually impaired person, By manufacturing the guide block, electromagnetic signals such as magnets and radio wave antennas are added to the molded body of the block for the visually impaired to provide various information electronically, and the electromagnetic information can be detected by the guide staff for the visually impaired The present invention relates to a gait guide block for a visually impaired person and a method of manufacturing the gait guide block for a visually impaired person.

The present invention relates to a walking guide block for a visually impaired person and a method of manufacturing the same, and more particularly, to an electromagnetic signal generator such as a magnet or a radio wave antenna, And more particularly, to a walking guide block for a visually impaired person and a method of manufacturing the same, which enables a visually impaired person to easily walk by implementing a walking guide block so that the miracle information can be detected by a guide wand for a visually impaired person.

Crosswalks are traffic signs installed on the roads to protect pedestrians from motor vehicle accidents or traffic accidents. Pedestrians are obliged to use the pedestrian crossing after confirming the pedestrian signal of the traffic light for safety, and the driver of the vehicle is obliged to suspend the vehicle when the pedestrian crosses. Furthermore, pedestrian safety is secured by installing overpasses or underpasses instead of pedestrian crossings at intersections or boulevards where there is a high risk of vehicle.

However, in the case of visually impaired persons who can not see the front, they can only guess the feature by a different sensation other than the sight, and can not identify the feature or the crosswalk with the naked eye.

For these visually impaired people, the signs for the blind are placed on the crosswalk or the traffic safety of the visually impaired is given through the buttons of the traffic lights located at both ends of the crosswalk. However, these methods often cause blind or visually impaired persons to be in danger due to breakage or malfunction of the button or signal lamp button, and there are occasions when the button is not even equipped. In addition, in the case of the conventional technique for guiding the visually impaired person through the guidance voice of the traffic light, the visually impaired person may not be able to perceive the visually impaired person due to the surrounding noise because of the dependency on the hearing.

In addition, since visually impaired persons have little visual discrimination ability, it is necessary to pay attention to such things as the entrance of the embassy, the entrance to the subway, the stairs, etc., as a means of providing convenience to the visually impaired, Braille blocks are added and used.

However, such a conventional braille block is sensed by only the protruding shape on the block which the blind is struck by the wand, and the types of messages transmitted to the blind according to the shape are classified into three types There is a problem that the speed of detection is inconvenient and inconvenient for the actual visually impaired to be guided and safely guided to the desired place with only these three kinds of messages when walking.

Accordingly, the disclosed technique solves the problems of the prior art, and further discloses a method and apparatus for assisting the visually handicapped in a safe pedestrian walk.

Hereinafter, a method for manufacturing a walking guide block for a visually impaired person according to the present invention will be described.

The method for manufacturing a walking guide block for a visually impaired person according to the present invention may be embodied by incorporating an electromagnetic signal generator into a molded body of a block by mixing or inserting the electromagnetic signal generator or by attaching a magnetic body to the surface of the molded body of the block, Or by attaching a magnetic tape with a magnetic pole to the surface of the inner and outer flooring materials.

3 to 6, 8, and 9, a method of imparting magnetism to the induction block includes a method of incorporating magnets, attaching a magnetic tape, or mixing ferrite in the mixing step of a ceramic raw material or cement, A block can be magnetized in whole or in part to enable signal input.

Further, in the case of coating or adhering a material capable of inputting signals to the surface of the block molding agent, the process can be much simplified. In this case, the durability of the adherend should be taken into consideration. Particularly in the case of using a ceramic material, Even if installed, it is possible to manufacture a block having excellent durability, firmness and surface.

Referring to FIG. 7, as an example of a block for inputting a signal by inserting a magnet as described above, the protrusion 44 and the protrusion 42 may be formed in the mold to facilitate insertion of the magnet, ) Is preferably as far forward as possible to the extent that it does not impair durability on the front side of the block, since it is advantageous to read the input signal. Further, the shape of the magnet M may be free, and it is preferable to use an annular magnet because it can form an even and large magnetic field in the range of formation of the magnetic field.

After the magnet M is inserted, the surplus space of the remaining protrusions can be filled with the bottom material. In this case, the inserted magnet is prevented from being detached, and in the case of a particularly bendy or rough road, , The inserted magnet can be completely fixed using silicon or the like. When inserting the magnet M, the pin extra space may be filled with another material that sticks to the floor.

When the cement is used as the binder 22 as the material for forming the block, the external properties are lower than those obtained by sintering the ceramic raw material, but the cost is significantly reduced. When inserting the magnet M, it is possible to insert the magnet physically before the hydration reaction of the cement is progressed without forming a protruding portion of the head of the pin especially in the mold. In this case, to fix the inserted magnet M, No further processing is required. In addition, even when ferrite is magnetized by mixing with cement, there is no need for a process such as sintering, so that the characteristics of the ferrite do not change. In addition, various materials can be used as the material for forming the molded body of the block.

The present invention is not limited to the above materials, but includes general rubber materials, tile materials, ceramics materials, and the like. In particular, when a rubber material is used, it has an impact resistance and a good shock absorbability that can not be obtained when a ceramic material or a ceramic material is used.

10 is a block diagram of a block for inputting a signal by inserting a conductor ML after forming a block with the above-described material. In this case, the intensity of the signal can be freely adjusted as compared with the case of inputting the signal by using ferrite, magnet, etc., and the signal can be freely changed after the construction of the block, and the signal can be transmitted more than the ferrite or the magnet Clearly, it has the advantage of no noise at the signaling stage. (However, in this case, there is a disadvantage that maintenance and maintenance costs are required since it is difficult to construct and the installation must be dependent on the external power supply continuously after construction).

Also, the electromagnetic signal generator provides an electric signal or a magnetic signal, and the electromagnetic signal generator selectively uses ferrite, a magnet, a conductor, or a radio wave oscillator. When the electromagnetic signal generator is formed of a magnetic body for providing a magnetic signal, the magnetic pattern of the magnetic body is formed into various shapes such as a straight line or a non-straight line, so that a visually impaired person holding a wand capable of sensing the electromagnetic signal Can be provided.

As described above, in the present invention, a walking guide block for a visually impaired person is manufactured so as to generate an electromagnetic signal on a molded body of a block, and a wand capable of detecting the electromagnetic signal is used to recognize a variety of information, You will be able to receive guidance steadily.
