【摘要】 针对目前市场提供给盲人的盲杖结构简单,智能盲杖智能性能低、导盲效果差等问题,本文以STM32为主控芯片,设计了一种新型的智能盲杖,解决盲人出行不便的诸多难题。该智能盲杖能在盲人出行时实时获取自己定位信息,利用多超声波系统探测盲人周围的障碍信息,盲人行走时盲杖以声光报警的形式提醒路人进行避让。通过MPU6050传感器解算盲杖的姿态信息实现盲人行走过程中意外跌倒的实时预警。所有信息通过WIFI方式发送到智能手机APP。通过盲杖敲击姿态解算,手机APP通过GPS调用百度地图获取盲人位置信息,位置信息和障碍信息通过科大讯飞语音模块进行播报。经实践应用,该导盲杖能给盲人出行带来较好的便利,同时具有使用简单,成本低等优点。更多还原

【Abstract】 Due to the simple structure, low intelligent performance and poor guide effect of the blind stick, a new type of intelligentblind stick is needed to be designed based on STM32 which is used as the main control chip to decrease inconveniences occur whenthe blind is out of home. The intelligent blind stick can acquire real-time location information, detect obstacles around the blindthrough multi-ultrasonic system, and warn passers-by though sound and light alarm. The attitude information of the blind stick iscalculated by MPU6050 sensor to realize the real-time warning of accidental fall while walking. All information is sent to smartphone APP via WIFI. By calculating the strike posture of the blind stick, the mobile phone APP which calledBaidumapcan obtainthe position information of the blind.though GPS At the same time,the position information and obstacle information can be broad-cast through the ITU voice module. Through practical application, the guide rod can bring more conveniences for the blind becauseof advantages of easier operation and lower cost.更多还原
