摘要
泄漏是长输管道运行中的重要事故。管道的腐蚀、突发性的自然灾害以及人为的破坏都会造成管道的破裂乃至泄漏,威胁到长输管道的安全运行,甚至造成巨大的经济损失。并经过多年的研究,已形成一套利用现代控制理论和信号处理技术进行管道泄漏检测和定位的方法。其突出的优点是能够适应管道系统的各种不确定性,并且便于在线实时监测。
Leak is a serious accident during the operation of long-distance pipeline. Pipeline breaking and leaking are caused by corrosion, paroxysmal natural disasters and man-made sabotage, which threaten the security of the operation of long-distance pipeline, even cause a substantial economic losses. For years of study, we have formed a system of pipeline leak detection and positioning utilizing modem control theory and signal processing technology. It has the merits to meet the uncertainty of pipeline network and is convenient to on-line monitor.
