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 STC12C5A60S2 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.
