Description
Technical Field
The invention relates to an intelligent sensing prompting blind road brick in the barrier-free field, which comprises a central processor chip, an intelligent collecting sensing control wireless receiving and sending module, two-dimensional codes, four-grid layout bulges and right-left oblique bulges with the mouth facing north, helps the blind, the old with low eyesight, the visually impaired people with short height, amblyopia and the like to distinguish the direction, and can prompt the blind to go home and turn around and the like in a voice manner after receiving and sending signals by a route detector and an intelligent mobile phone.
Background
The blind sidewalk is an important barrier-free infrastructure of each city, and blind sidewalks laid at home and abroad are reasonable to guide the blind men to move forward by using bar-shaped bricks formulated in the United states in 1961, all turning intersections of upper and lower steps are only partially full of dotted bricks, so that the blind men cannot go up and down the steps or need to turn, the blind men cannot find intersections needing turning such as self-returning, the unreasonable design is that hundreds of buses in a city write 1-way vehicles, the blind men cannot use the vehicles at all, and the national financial resources are greatly wasted.
The independent trip is the wish of each serious blind person and the hyphenation of doing people, in order to have the hyphenation independent trip, the blind persons hope to have a navigation device for avoiding obstacles for trip, after the blind persons experience various voice prompt navigation devices for the blind persons in Beijing assistive instrument exhibition for many years, the blind persons find that various voice prompt trip navigation devices are pedestrian places such as roads, overpasses, tunnels, buses, subways, trains, airports, and the like, the blind persons hear the voice prompt that pedestrians turn left in front and the pedestrians and then hear the prompt that the pedestrians turn right in front, and under the condition that the pedestrians are normal, the serious blind persons who cannot see the obstacles do not dare to step in front, therefore, the problem to be actually solved in the barrier-free field is that the blind persons can step on the feet to identify the direction and give a detailed prompt that each intersection turns by using ears, and ensure that the blind road is smooth without the obstacles, the pedestrian can help the severely blind people to independently walk out of the house after actively giving way to the blind people without obstacles.
Disclosure of Invention
The invention aims to provide an intelligent sensing prompting blind road brick which is designed according to the principle that a blind person does not look at a road with eyes but walks with feet stepping on a way to explore and listening to sound with ears, is provided with a central processor chip, an intelligent collecting sensing control wireless receiving and transmitting module, a two-dimensional code, four-grid layout bulges and left and right oblique bulges with the mouth facing north, helps the blind person, the old with low vision, the visually impaired people with short height, amblyopia and the like to distinguish the direction by stepping on the feet, and can prompt the blind person to go home and turn around and other detailed information of each road junction in a voice mode after receiving and transmitting signals by a road explorer and a smart phone for the blind person.
The intelligent sensing prompting blind road brick is characterized in that: according to the principle that the blind people walk by hearing ears and stepping on the feet to explore the way, indoor and outdoor crossroads, T-shaped roads, midway zebra crossing intersections, overpasses, tunnels, all-road lipstick and green light information, east-west, south-north directions, street names, trains, roads, land and water, buses, subways, elevators going up and down stairs, the blind people go home, toilets, schools, hospitals, governments, civil administration, justice, disabled unions, banks, post offices, hotels, restaurants, supermarkets, rehabilitation, massage mechanisms and detailed information of the positions of the four-grid layout bulges under the bricks are stored in a circuit board central processor chip and a two-dimensional code, and are used for automatically sending vibration signals to a wireless intelligent sending and receiving sensor under a route detector or mounted on a mobile phone for the blind people through an intelligent collecting and sensing control wireless sending and receiving module and converting information characters stored by the circuit board central processor chip and the two-dimensional code into voice to inform the blind people, when the solar energy storage power supply module cannot supply power to the blind person detector to prompt each intersection information in a way that the blind person cannot receive voice, the blind person can step on the left inclined convex chamber, the left inclined convex chamber is paved towards the north, the four grids under the opening are arranged to be convex with 1 point on the left lower side, 2 points on the right upper side and the right lower side, the upper left 1 point, the upper right 1 point, the upper left 1 point, the upper right 2 point, the upper left 2 point, the upper right 1 point, the upper left 1 point, the lower right 1 point, the upper left 1 point, the lower right 2 point, the upper left 1 point, the upper right 1 point, the upper left 1 point, the upper right 2 points, the left point and the upper right 1 point, 1 point on the upper left, 1 point on the lower right, 1 point on the upper left, 2 points on the lower left, 1 point on the upper right, 2 points on the upper left, 2 points on the upper right and the lower right, 1 point on the lower left, 1 point on the upper right, 1 point on the upper left, 2 points on the upper right, 2 points on the upper left, 2 points on the upper right and the lower right, 2 points on the upper left and the upper lower left, 2 points on the upper right and the lower right, 2 points on the upper left, 2 points on the upper right, 2 points on the upper left and the lower right, 2 points on the upper left, 2 points on the upper right and the lower right, 2 points on the upper left and the upper right, the left lower 1 point, the right upper 1 point and the left lower 2 points, the gap faces forward, the gap faces backward, the brick shape is realized by stepping on the convex point with the foot, the user can know that the user walks to the position needing turning, and the left and right oblique protrusions can be spread towards the north through the foot to distinguish the directions of east, west, south and north.
The national standard for the length and width of the blind road stipulates 30 cm, so that the identification difficulty of the blind wearing thick-sole shoes can be reduced by 10% by reducing one bulge on one brick. The intelligent sensing prompting blind road brick has a brick shape with at most 8 bulges at 2 points of the left upper part and the lower part, 2 points of the right upper part and the lower part, and 2 points of the left upper part and the right upper part and the lower part, and obviously reduces 28 bulges compared with the existing brick shape with at most 36 points on one prompting brick of the existing blind road at home and abroad.
