摘　　要：针对井下环境复杂多变,普通的流速测量方法不能满足实际需求的现状,设计一种基于LMS最小均方算法,以AVR单片机ATmega128为主控制器的流体流速测量系统。首先概述了流体流速测量的基本原理,并分析了最小均方算法的计算过程以及在流速测量中的应用,最后介绍了系统中的硬件部分以及其在整个系统中的功能作用,并用实际的测试结果来验证了系统的可实施性,从而为实现煤矿的安全生产提供可靠的决策依据。Underground environment is complicated and changeable,however,the general methods can not satisfy the actual demand. To improve the present situation,flood flow velocity measurement system based on LMS mean square and adopted AVR ATmega128 as main controller was introduced. First,the fundamental principle of the measurement was introduced,and the approximate computational process as well as the application of the measurement of the LMS was analyzed. Finally,the hardware part of the system and its functions were introduced in the whole system. And,the experimental results verified the implementation of the system to provide reliable decision basis for the safety production of coal mine.
