INTELLIGENT GUIDE DEVICE BASED ON ULTRASONIC WAVE FOR RANGE ACQUISITION

摘要：

In this paper, an intelligent guide device which is based on ultrasonic wave has been designed for range acquisition.With MSP430F169 single chip as its core, this guide device combines with active ultrasonic detector so as to improve the method of time to confirm the distance and location between the sensor and reverberation. Furthermore, this device can provide promptly abundant voice for the blind through the MP3 connected with it.The design of the detector on this guide device is spin scanning,which can solve the problem of fade zone caused by direction angle.This device which has high accuracy of measurement and can be implemented easily has significant practical value.
