一种基于单片机的智能盲杖系统

An MCU-Based Intelligent Blind Stick

传统盲杖功能单一,除了提供手臂延伸的触感功能之外,无法为存在视力障碍的人员提供更好的用户体验。针对传统盲杖的不足,提出了一种基于单片机的智能盲杖设计,在保留盲杖原有基本功能的基础上增加智能手机接口、GPS/北斗定位、语音播报、超声避障等功能。智能盲杖设计具备多种应用功能,为盲人提供智能化的出行服务。

In addition to its single function of arm extension,the traditional blind stick is unable to provide a better user experience for people with visual problems.In view of the shortcomings of the traditional blind stick,the design of an intelligent blind stick based on single chip microcomputer is proposed.With more functions like smart phone interface,GPS/BeiDou positioning,voice broadcasting,ultrasonic obstacle avoidance added,the intelligent blind stick is expected to better help the blind travel around.
