摘要

针对T型水听器灵敏度高

低频特性好

抗干扰能力强等优点

设计开发了一种单片机控制的水下声波测距系统。以声波在水中的传播速度为确定条件

使发声换能器发射声波

水听器接收声波

通过AT89S52单片机对声波测距系统的发射、接收时间的控制

计算出障碍物与水听器之间的距离。测试结果表明:系统可以稳定接收反射声波信号

实现短距离测量

测量误差小于1%。

Abstract

Aiming at advantages of T type hydrophone

such as high sensitivity

low-frequency and strong anti-interference ability

an underwater acoustic ranging system controlled by MCU is designed and developed.Propagation velocity of sound in water is used as determined conditions

sound wave is sent by transducer and received by hydrophone.AT89S52 is used to control time of sending and receiving

distance between obstacles and hydrophone is calculated.Test results show that this system can receive the reflected sound wave signal stability

and achieve short-distance measurement and the measuring error is less than 1 %.
