摘要
超声波因指向性强、能量消耗缓慢且在介质中传输距离较远,常用于距离和位移的测量。本文基于IAP15W4K58S4单片机,设计了一种简易、便携、低成本的超声波测距系统,重点介绍了超声波发射电路、超声波接收电路、温度补偿和系统软件的设计。经测试,该系统可以实现稳定、可靠、精确的距离测量。
Ultrasonic is commonly used in the measurement of distance and displacement due to its strong directivity,slow energy consumption and long transmission distance in the medium.Based on IAP15W4K58S4 microcontroller,a simple,portable and low cost ultrasonic ranging system is designed.The design of ultrasonic transmitting circuit,ultrasonic receiving circuit,temperature compensation and system software are mainly introduced.After testing,the system can achieve stable,reliable and accurate distance measurement.
