摘　　要：介绍了输油管道泄漏的检测、定位方法及其应用现状。详细分析了负压波法泄漏检测的原理与定位算法,并对该定位算法中所需要的关键参数,即首、末两端压力传感器接收到压降信号的时间差,利用小波变换法进行了深入的研究与分析,并用Matlab上进行了模拟仿真,结果表明该方法简易可行、定位准确,达到了对精度的要求。Briefly introduces the methods of the leakage of oil pipeline detection and location. Meanwhile, this paper analyses the principle of the leakage detection of the negative pressure wave, localization algorithms and the key parameters required in the positioning formula in detail, which means the time difference of pressure drop of signal received by sensor in the initial and terminal position, the deep research and analysis by using the method of wavelet transform and the relevant simulation performed on the Matlab, the results show that the method is simple and feasible, accurate positioning, reached the requirement of accuracy.
