智能盲人导航手杖设计

Design of Intelligent Navigation Cane for the Blind

主要基于STM32 F103系列单片,集成GPS模块、超声波测距模块和语音播报模块等功能模块,采用单元模块化的设计方法,设计了一款集电子罗盘、超声波避障、 GPS定位、电子围栏和跌倒警报等功能于一体的智能盲人导航手杖设备和与其搭配的手机软件APP,用于辅助盲人独立安全出行。通过理论分析和实验验证,该智能盲杖的造价低,可复制性强,具有很强的实用性、商业价值和现实意义。

Based on the STM32 F103 series of single-chip microcomputer,integrated GPS module,ultrasonic ranging module,voice broadcast module and other functional modules,using unit modular design method,an intelligent navigation cane device for the blind which integrates electronic compass,ultrasonic obstacle avoidance,GPS positioning,electronic fence,fall alarm and other function and its matching mobile phone software APP are designed,which are used to assist the blind to travel independently and safely.Through theoretical analysis and experimental verification,the intelligent blind stick has low cost,strong replication,and has strong practicability,commercial value and practical significance.
