Road guidance system for visually impaired

Abstract

The present invention relates to a road guidance system for the blind, and the invention comprises: a plurality of RFID tags (10) which are buried inside a pedestrian pavement (100) by allowing information of said pavement (100) to be contained therein, along the pavement on which Braille blocks are formed or the pavement on which forming Braille blocks is difficult; a guide robot (20) which has an RFID reader (21) for checking signals of said RFID tags (10) from said pavement (100) by passing therethrough, and an obstruction sensor (22) for sensing an obstruction ahead at a certain distance, wherein wheels (23) are positioned on both sides of the guide robot such that the guide robot advances or retreats by the driving of a motor (24); a controller (30) which checks signals from said RFID reader (21) and said obstruction sensor (22) inside said guide robot (20), converts the checked information into voice signals and outputs the voice signals, and then controls the driving of said guide robot (20); and a stick (40) which is connected such that a lower end thereof can be assembled in said guide robot (20), and is electrically connected to enable communication with said guide robot (20), thereby enabling safe loading and unloading. Particularly, the invention enables a blind person to conveniently adjust a moving speed of the guide robot by a blind person's will and to recognize, in advance, any obstructions or stairs or the like ahead, whereby the invention enables safer walking guidance and prevents collisions.

Description

technical field [0001] The present invention relates to a road guidance system for the visually impaired. More specifically, it relates to a method of embedding RFID tags along the road for people to walk on, so as to remember the nearby road information and continuously sense the front when walking. It is a road guidance system for visually impaired people that can confirm the information ahead through voice in advance and guide people to walk safely. Background technique [0002] In general, various devices for safe walking, such as crutches, have been developed and proposed for visually impaired persons to walk safely. [0003] Most of the visually impaired currently rely on sticks for the blind, and they also use guide dogs according to their economic capabilities. [0004] For the visually impaired, special blind spot bricks for the visually impaired are installed on the road, so that the visually impaired can walk safely. [0005] But described auxiliary device just ...

Problems solved by technology

[0008] However, even if the road information is obtained in advance, since the visually impaired person pushes the guidance device and turns the direction, when leaving the area with blind spot bricks or RFID markers, he will feel uneasy and become disoriented, which is dangerous, especially if there are steps or obstacles ahead. When things wait, conflicts cannot be prevented
