基于单片机的智能拐杖软件设计

Intelligent crutches hardware design based on SCMAbstractWith the continuous development of science and technology andmanufacturing in China,people use in everyday life and industrialproduction automation control technology has been widely applied,notonly save the human resources,and greatly improve the people's life theefficiency of production,not only promoted the rapid development ofscience and technology,and constantly enrich people's life.The research and development of guide for the blind has always been afocus of scientific research in various countries,not only because ithas great social significance,but also because it has great researchsignificance in many research fields such as robot vision.The guideequipment that can provide road information to humans can also play thesame role in automated robots.There have been many successful studies.This design USES stc89c51 microcontroller as the main control board,hc-sr04 ultrasonic ranging sensor as the detection device,to achieve theeffect of guide for the blind.This instrument is simple in structure andreliable in function.It can detect obstacles in front of it.When reachingthe preset range,the buzzer will remind the user to be careful ofobstacles,thus achieving the effect of intelligent guide for the blind.Keywords:STC89C51 SCM HC-SR04 ultrasonic ranging sensor
