Blind person reminding waistband and control method thereof

Abstract

The invention relates to a blind person reminding waistband which comprises a waistband body, a waist button and a fastener. The waist button and the fastener are arranged at two ends of the waistbandbody, the fastener is connected with the waist button in a clapped manner, two ends of the waistband body are connected into a ring, ultrasonic transceivers, infrared transceivers and vibrators are arranged on the waistband body, a wiring groove of an electrical wire is formed in the waistband body, a control unit is arranged in the waist button, a button is arranged on the surface of the waist button, the ultrasonic transceivers and the infrared transceivers are alternately arranged on the outer surface of the waistband body, each vibrator is arranged between each ultrasonic transceiver andthe corresponding infrared transceiver and on the inner surface of the waistband body, and electrical wires of the ultrasonic transceivers, the infrared transceivers and the vibrators are electricallyconnected with the control unit through the wiring groove. The blind person reminding waistband solves the problem that a waistband is easily interfered by the outside in a noisy environment, barriers can be comprehensively sensed, fixed and movable objects are distinguished and fed back, and a blind person are effectively reminded of surrounding barriers and can sense orientations of the barriers.

Description

technical field [0001] The invention relates to an article for the blind, in particular to a reminding belt for the blind. Background technique [0002] The traditional blind-guiding product is the blind-guide stick. Blind people need to hold the blind-guide stick with a high degree of concentration while walking for a long time and touch the surrounding ground and obstacles. Guide the blind in this way, which is a waste of time and cannot be completed in time. Sensing the surrounding road conditions and obstacles, the guide stick can only sense stationary obstacles but cannot perceive the moving body moving toward the blind person, and once the guide stick leaves the palm for various reasons, the blind person will have no way to continue walking , and personal safety cannot be guaranteed, which is very dangerous. [0003] The guide products on the market today mainly include: ordinary guide sticks, electronic guide sticks, guide glasses and guide dogs. [0004] [0005...

AI Technical Summary

Problems solved by technology

However, the detection range is still only the front side of the blind person. If there is an object approaching rapidly from behind, it will not be prompted.

The guide glasses using ultrasonic technology on the market can only detect a distance of 60 cm, and cannot detect very close objects (such as within 30 cm)

[0009] Guide dogs are a relatively good choice, but the training process is rigorous and the price is too expensive
