为提高学生对超声波的实际应用能力，在超声波测距技术的基础上，引入广泛应用于海洋探测方法中的双频超声波探测技术设计了一个导盲实验。该导盲系统能够在十几米甚至二十米的范围精确地探测障碍物距离，同时具有大量程与高精度两大优势，且采用太阳能供电，报警装置还可以播报障碍物距离。

In order to improve students’ ability about putting ultrasonic sound into application,based on the traditional technology of ultrasonic distance measurement, the paper uses the technology of double-frequency ultrasonic distance measurement that has been widely applied into the ocean exploration to design a kind of guide experiment,which cannot only enlarge measurement range but also measure the barrier’ s distance pre-cisely. Besides,it uses solar energy to power the system, and the warning module has the function of audio broadcast.
