基于红外探测器的三角测距原理和光电传感技术,设计了一种新型的智能导盲系统。该导盲系统以Arduino单片机为控制核心,三个方向的红外探测器采集周围障碍物信息,通过一定的优化算法编写程序,读取周围障碍物信息,判断需要报警的方向,控制蜂鸣器和MP3模块的双语音报警系统,确定行走方向。该系统提高了报警的及时性和精确度,能够很好地引导盲人避开障碍物,安全快速地行走。

Based on triangle metering distance principle of infrared detectors and photoelectric sensor technology, a new type of intelligent blind-guiding stick is designed. The core of the device is the Arduino singlechip, with three infrared detectors detecting the obstacle distance data from different directions, which is read, operated and optimized by the singlechip. Then, the Arduino singlechip control buzzer prompts and MP3 voice prompts to tell the blind walker the correct direction. Due to the timeliness and accuracy of the alarm system, this blind-guiding stick can guide blind walkers to bypass the obstacles and walk safely and quickly.
