一种智能产品盲人拐杖控制电路开发

Development of Control Circuit of a Smart Blind Walking Stick

由于盲人在行走时无法了解到前方是否有障碍物,给他们所带了许多不便。针对此问题,本论文开发了一种基于单片机控制及超声波探测的盲人避障装置,此装置带有语音及振动提示功能,以及LED提示灯。通过超声波来探测前方一段距离内是否有障碍物存在,如果存在,则语音提示模块发出提醒信息,同时振动模块也会工作,产生振动。且该装置可以放在拐杖上,便于行走携带,有实用意义。

Because blind people can＇t understand whether there are any obstructions in front of them when walking, which has brought a lot of inconvenience to them. To solve this problem, this thesis develops a blind obstacle avoidance device based on single-chip microcomputer control and ultrasonic detection. The device is equipped with voice and vibration prompting function and LED warning light.The presence of obstacles within a certain distance in front is detected by ultrasonic waves. If there is an obstacle, the voice prompt module issues a warning message, and the vibration module also works to generate vibration. And the device can be placed on a crutch for easy walking and carrying, which is of practical significance.
