摘要
以ATmega 64单片机作为主控制器,设计了一种基于超声波、红外测距原理和GSM数据传输的多功能智能导盲系统.此系统包括超声波测距、红外测距、语音提示、电子罗盘、GSM模块等部分,采用超声波和红外传感器探测障碍物,采用电子罗盘检测行走方向,并将障碍物信息和方向信息以语音的方式提示给盲人,达到导盲作用.最后对测距误差和系统测障盲区进行了研究.
Abstract： With ATmega 64 single-chip microprocessor as the main controller, multifunetional intelligent guiding system was designed based on ultrasonic, infrared ranging principle and GSM data transfer. The system includes ultrasonic ranging,infrared ranging, sound reminder, electronic compass and GSM module, etc. This system uses ultrasonic and infrared sensor for detecting obstacles,electronic compass for detecting walking directions and guides the blind to judge through obstacle and direction messages by a sound reminder, then accomplishes the purpose of guiding the blind. Finally, the ranging error and measuring blind zone is studied.
