📦 基于STC89C516单片机的多功能导盲杖的设计 - 免费下载

导盲杖是盲人群体出行最基本的工具之一,为了解决盲人群体因传统导盲杖功能单一、设计缺陷而导致出行不便的问题,团队经过结构设计改良、硬件选型搭配和软件功能实现等步骤设计出一款多功能导盲杖。该设计参考了人机工程学理论设计改良导盲杖的结构,系统以嵌入式微控制器STC89C516为控制器,超声波模块为避障装置,GPS模块为定位导航装置,辅以LED灯条、震动马达和ISD1420语音模块为报警呼救装置,来实现盲人安全独立出行的功能。研究成果显示,该款导盲杖初代实体已基本实现盲人在普通人行道安全出行的功能。

The guide cane is one of the most basic tools for blind people to travel.In order to solve the problem of inconvenience caused by the single function and design defects of the traditional guide cane,a multifunctional guide stick is designed by our team through the steps of structural design improvement,hardware selection and software function realization.The design refers to the ergonomic theory design to improve the structure of the guide cane.In the system,the embedded microcontroller STC89C516 is used as the controller,the ultrasonic module is the obstacle avoidance device,and the GPS module is the positioning navigation device;supplemented by the LED light bar,the vibration motor,and the ISD1420 voice module as the alarm calling device,so as to realize the function of safe and independent travel for the blind.The research results show that the first entity of the guide cane has basically realized the function of the blind person to travel safely on the ordinary sidewalk.
