在日常生活中,视障人士需要依赖于盲杖行走,但是传统的盲杖只能手动检测较近的障碍物,无法提供更为全面的周围环境信息。视障人士出行的难度不仅限于路况、障碍物的检测,还涉及行进方向需求、环境指示等方面的问题。因此,基于STM32设计了一款新型的智能导盲杖,集成各种外围检测电路,如光照检测电路、超声波电路、语音提示电路、GPS定位电路、角度检测电路等,能够实现光照检测、超声波测距、GPS定位、摔倒检测、短信发送、行进距离估算等功能,支持夜间使用,从而解决视障人士的出行困难问题。

In daily life,visually impaired individuals rely on white canes for mobility.However,traditional canes can only manually detect nearby obstacles and fail to provide comprehensive environmental information.The challenges of navigating for the visually impaired extend beyond detecting road conditions and obstacles to include determining directional needs and environmental cues.Therefore,a novel smart guide cane based on the STM32 microcontroller has been designed.It integrates various peripheral detection circuits,including light detection,ultrasonic sensing,voice prompting,GPS positioning,and angle detection circuits.This device enables functions such as light detection,ultrasonic ranging,GPS positioning,fall detection,SMS sending,and distance estimation.It supports nighttime use,thereby addressing the mobility challenges faced by the visually impaired.
