盲人辅助行走拐杖的设计

Design of blind assisted walking stick

传统盲人的拐杖仅仅是一根普通长棍,盲人只能感觉接触到的障碍物,使得他们在行走中充满了安全隐患。针对这个问题,本文基于STC单片机设计了一种盲人辅助行走拐杖,该设计模仿蝙蝠避障原理,利用嵌入式技术和超声波测距技术,探测盲人正前方的障碍物,由单片机控制收集信息,并利用相关软件处理,对需要进行警告的信息进行人性化语音提示。实验结果表明设计的盲人辅助行走拐杖能够有效帮助盲人识别障碍物与自己之间的距离远近,供盲人提前作出应对方案,减少行走过程中的危险,从而达到辅助盲人独立行走的目的。同时拐杖采用特制的可伸缩折叠结构,使之更加便于不同的用户群使用。

Traditional blind crutch is just an ordinary stick, obstacles blind people only feel touch, make them in the walk with hidden safety trouble. Aiming at this problem, this paper based on the STC microcontroller design of a blind auxiliary walking stick, the designed to mimic the bat avoidance principle, using the embedded technology and ultrasonic ranging technology, obstacle detection in front of the blind, controlled by microcomputer to collect information, and the use of related software, human voice prompts the need for warning infm^ation. Experimental results show that the design of blind auxiliary walking stick can provide effective help the blind identification of obstacles and their distance, for the blind to that plan, reduce the risk in the process of walking, so as to help the blind to walk independently objective. At the same time, stick with special telescopic folding structure, make it more convenient for different user groups and use.
