| 英文摘要 | 根据声的发射、反射及传输理论推出并用实验验证了测距回波包络曲线的近似方程，据此提出了一种高精度超声波测距信号处理方法.介绍了以单片机实现该方法的超声测距系统，该系统在2.5~12M范围内测距误差不大于0.25%.; Based on the theory of ultrasonic′s launching, reflecting and transmitting, an approximate equation descrbing the envelope of reflecting signal is derived and then verified experimentally.After that,a highaccuracy detection processing method is presented and a practical system realized with a 8051 single chip microcomputer is introduced.Distance measurement tests between 2.5 ～12 m show that its accuracy is satisfied.; 国家863计划 |
