| 摘 要： | 在此为盲人设计了一种基于STM32的超声相控阵导盲避障系统,主要涉及到系统的硬件设计部分,以及超声相控阵识别几种障碍的方法。该系统以意法半导体的STM32微控制器为核心,主要包括超声发射电路,回波信号接收与放大电路,以及回波信号的处理与分析。该设计能够探测前对前方宽1.5 m纵深2 m的范围进行探测,能够分辨狭窄通道、台阶、沟壑以及柱状障碍物等,使盲人行动时更加方便。并且该系统功耗小,成本低,具有很好的使用价值。

| Abstract: | At present,there are more than thirty millions of the blind people in the world.A system of ultrasonic phased arrays guidance system for the blind.was designed.The architecture of this design is introduced.The system takes STM32 microcontroller as a core which includs ultrasonic emission circuit,echo signal reception and amplification circuit,and processing and analysis functions of echo signal.The system can detect a range of 1.5 m×2 m in front of the blind,and distinguish narrow channels,steps,ravines and cylindrical obstacles.The system has the advantages of low power and low cost. |
