Design of Intelligent Navigation Cane for the Blind
Based on the STM32 F103 series of single-chip microcomputer,integrated GPS module,ultrasonic rang-ing 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 posi-tioning,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 ver-ification,the intelligent blind stick has low cost,strong replication,and has strong practicability,commercial value and practical significance.
