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 approxi-mate 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 sys-tem to provide reliable decision basis for the safety production of coal mine.
