Blind-guiding method

Abstract

The invention relates to a blind-guiding method which includes steps of: 1) acquiring a target address; 2) activating an RFID tag in a navigation device; 3) acquiring position information of the RFIDtag; 4) forming navigation information according to the position information and target address; and 5) generating prompt information according to the navigation information. The blind-guiding methodis based on a ground navigation apparatus, wherein in the method, a wireless blind way is paved on road surface by means of a navigation device with a built-in RFID tag, so that normal travelling safety demand of a blind person is satisfied. Meanwhile, the navigation device is in the form of bricks, so that the device can be paved along with other bricks on the road without addition of work load,and also can be established by simple modification of a common road surface in a single-block replacement manner, thereby achieving the blind guiding function.

Description

technical field [0001] The invention belongs to the technical field of RFID navigation, in particular to a blind guiding method. Background technique [0002] At present, there are about 45 million blind people in the world, and 180 million people are visually impaired, while the total number of blind people in China accounts for about one-fifth of the total number of blind people in the world, reaching 9 million; at the same time, there are about 7 million people in the world every year become blind. As we all know, people get most of the information through vision in the process of life, and blind people lose their vision, which brings a lot of inconvenience to their work, life and study. Safe travel is the most important issue in the life of the blind. [0003] With the continuous improvement of economic development and social civilization, people pay more and more attention to solve the problem of blind people's activities in public areas. Existing blind-guiding metho...

AI Technical Summary

Problems solved by technology

Among them, the blind path requires an independent paving space and is easy to be damaged and occupied. Due to the inconvenience of using the blind path and the potential safety hazards, the actual utilization rate has not been high; GPS positioning has problems such as low accuracy and high cost, and it cannot be realized in the field of blind guidance. wide application

[0004] At present, there are at least the following problems in the prior art: the blind path in the existing blind-guiding method can only remind the blind person to move forward or turn, and cannot provide more information about the surrounding environment and destination for the blind person; and the blind path and Ordinary sidewalks need to be laid separately, blind people cannot share ordinary sidewalks, and their range of activities and travel routes are greatly restricted; existing digital navigation methods such as GPS positioning have low navigation accuracy and difficult operation for blind people, and cannot effectively provide navigation for blind people
