摘要:
相关检测技术是为了取得某些物理量而利用自相关函数和互相关函数运算检测某种物理量的技术，可用于管道泄漏检测，特别是负压波泄漏检测和流量泄漏检测。结合相关函数的性质和原理，
分析了其在管道泄漏检测中的应用原理，以及泄漏点定位的计算方法，提出了输油管道泄漏检测定位的方法：利用声波传感器检测由泄漏产生的声波振动信号，再利用相关技术确定不同传感器输出
信号的延时，根据传感器的几何分布和声波传输速度，对泄漏点进行定位。采样时间和阈值的选取直接影响泄漏检测的灵敏度和可靠性，在进行相关函数计算之前需消除杂音，防止泄漏信号被屏蔽
。现阶段该检测技术只适用于突发、快速泄漏的检测定位，不适用于工程中的缓慢泄漏。
Abstract:

In order to achieve detection to certain physical quantities，self-correlation and interrelation functions are used in correlation detection technology，which can be used in pipeline leak inspection，especially in negative pressure wave and flow leak inspection. Combined with the characteristic and principle of correlation functions，their application principle in pipeline leak inspection and the method of leak location calculation are analyzed，and location method of leak detection for oil pipeline is proposed. This method uses acoustic sensors to detect sound waves generated by the leakage of vibration signals and relevant technology to determine the delay of different output signals，and then locate the leak point according to the distribution of sensors and acoustic transmission speed. Sampling time and threshold directly affect the sensitivity and reliability of leak inspection. Noise elimination is necessary before correlation function calculating to avoid shielding of leakage signals. The current inspection technology is only applicable for location of sudden and rapid leak，but not for slow leaks in actual pipeline engineering.
