| 摘 要： | 介绍了一种采用脉冲回波方法，基于单片机的超声波测距系统。充分利用单片机的软、硬件资源，自动实现超声波的发射与接收控制。系统考虑了环境温度对超声波的传播速度的影响，通过单片机中计数器所计超声波往返所经历的时间，经过换算得到超声波传感器与反射物之间的距离。

| Abstract: | Introduced one ultrasound distance measurement system of using pulses echo method based on single-chip microcomputer. Made the most of software and hardware and implemented automatically control transmit and receive of ultrasound. Taking into account of influence of environment temperature to speed, countered the time and then converted and got the distance between ultrasound sensor and reflector. |
