摘要
本文介绍一种利用声波测量管长的单片机系统,测量精度可达2‰~3‰,且有较强的抗干扰能力。系统的微机部分用89C51单片机,并用Newton插值算法来补偿其非线性。
This article introduces a computer system which uses sound wave to measure the length of oil pipe. Its measure precision can up to 0. 2 percent, and it has a strong disturb resist capability. The system has 89C51 as its computer part, and uses Newdon insert algorithm to compensate its non linearity.
