【摘要】：随着管道工业的迅速发展,输气管道的泄漏不止造成能源浪费、污染环境,还会对人们生命财产安全造成威胁,对泄漏进行检测和定位具有非常重要的理论意义和应用价值,其中声波法是当前研究的热点.声波中的动态压力波幅值大,包含频率范围宽,因此基于动态压力波的泄漏定位技术是未来最有潜力的输气管道泄漏监测技术之一.声波的产生和衰减对该方法的检测准确度和定位精度有决定性影响.本文从声波法输气管道泄漏监测技术的原理、近5年研究状况、展望三个方面总结介绍基于声波的输气管道泄漏检测和定位研究现状及未来发展方向,重点分析国内外对声波法泄漏监测技术的的研究.
[Abstract]:With the rapid development of pipeline industry, the leakage of gas pipeline not only causes energy waste, pollutes the environment, but also threatens the safety of people's life and property. It has very important theoretical significance and application value to detect and locate the leakage. Among them, acoustic wave method is the focus of current research. Because the amplitude of dynamic pressure wave in acoustic wave is large and the frequency range is wide, the leak location technology based on dynamic pressure wave is one of the most potential leakage monitoring techniques for gas pipeline in the future. The generation and attenuation of sound waves have a decisive effect on the detection accuracy and positioning accuracy of this method. In this paper, the principle of acoustic gas pipeline leakage monitoring technology, the recent five years' research situation, and the present situation and future development of acoustic wave based gas pipeline leakage detection and location research are summarized and introduced in this paper. The research of acoustic leakage monitoring technology at home and abroad is analyzed emphatically.
