Intelligent guiding system special for blind person

Abstract

The invention relates to the field of auxiliary appliances for blind persons, in particular to an intelligent guiding system special for a blind person. The system comprises a walking stick, glasses, a cloud server and a mobile terminal, the walking stick is in wireless connection with the glasses through Bluetooth, and the glasses and the mobile terminal are connected with the cloud server through a wireless network. The walking stick and the glasses are held by the blind person, provide obstacle avoiding and guiding service for the blind person and meanwhile can position the blind person and upload the position information to the cloud server. A map is stored in the cloud server, a navigation route can be provided for a blind user according to the set starting point, and meanwhile the real-time position of the blind user can be stored according to certain coding. The mobile terminal is held by a guardian of the blind user, can load the position of the corresponding user from the cloud server according to the coding and timely positions the blind user. By means of the intelligent guiding system, the blind guiding stick and the blind glasses are combined, data transmission and sharing can be achieved through a cloud platform, it is convenient for the blind person to go out, and safety of the blind person is guaranteed.

Description

technical field [0001] The invention relates to the field of assistive devices for the blind, in particular to a special intelligent guidance system for the blind. Background technique [0002] Blind people have difficulty traveling due to physical defects. The traditional blind-guiding tool is the blind-guiding stick, but the blind-guiding stick only senses the obstacle by contact, and it can only be sensed when it is very close to the obstacle, which makes the blind person unable to respond in time, which causes the blind person to fall from time to time . With the advancement of science and technology, new blind guide crutches are increasingly incorporating electronic control technology, which detects obstacles and their distances through various sensors, and reminds blind users. Such crutches all have the problem of inaccurate measurement data when the angle of the sensor is fixed and the inclination angle of the crutch is unreasonable. In addition, the guide crutches...

AI Technical Summary

Problems solved by technology

This kind of crutches has the problem of inaccurate measurement data when the angle of the sensor is fixed and the inclination angle of the crutches is unreasonable.

In addition, the guide crutches can only detect obstacles on the ground in front of them and play the role of obstacle avoidance, but they cannot identify the user's location through the surrounding environment signs, and cannot provide users with accurate location information.

Of course, there are also guide crutches that provide users with location information by installing a positioning module, and can also be bound to the mobile phone of the user's family to transmit location information. However, this method is mostly a one-to-one mode, and the system integrity is not strong. Resource reuse rate is low
