摘　　要：设计了一种以超声波测距和PSD红外测距为核心的智能语音导盲器。利用STC12C5A60S2单片机循环采样,ISD1700语音芯片作语音提示,实现导盲提示的功能。整个导盲装置将放置于使用者头部,其中,超声波探测器探测方向可随使用者头部指向变化而变化,探测距离为5 m,精确到百分位,通过耳机向使用者报数,实现方向与距离的精确指示。A smart blind guider was designed, which mainly consists of ultrasonic ranging sensor and PSD infrared ranging sensor. The function of intelligent speech prompt of the blind guider is realized by cycling sampling of MCU STC12CSA60S2 and sound chip ISD1700. The device is placed on user＇s head. The direction, to which the device points, is in line with the movement of the user＇s head automatically. Then the result in the form of verbal signal will be sent to user＇s headphone to real- ize 100% accurate acquisition of direction and range within 5 meters.
