摘　　要：基于声学原理开发出一套泄漏信号检测算法,提出使用函数拟合方法寻找音波起始点,计算音波在管路介质中的船舶时间差判断泄漏点。经过单管道及"目"型管道的试验验证,最大误差为3个采样点间隔,平均为0. 8个采样点间隔。A function fitting method was proposed to find the starting point of the sound wave to calculate the time difference of the sound wave in pipeline medium to judge the leakage point.The results of pipeline testing showed that the maximum error is3sampling points interval,with an average of0.8sampling points interval.
